Description of the Invention: [Technical Field] The present invention relates to a blasting chamber or a working chamber for use in a sandblasting process (in the present specification, abbreviated as "sandblasting chamber"), and specifically, Regarding a blasting chamber in which a working space is formed, the working space is large enough that one or more X authors can work with the workpiece when a relatively large-sized workpiece to be processed is to be subjected to a sandblasting process. And the work space is adapted to be suitable for sandblasting and painting by not only allowing the sandblasting process but also allowing the workpiece to be painted in the same space after the sandblasting process. 3 In the present invention, the term "blasting process" is applied in the broadest sense; 彡 includes various types of processes, such as dry jetting or projection (hereinafter referred to as "jetting"), and also includes projection. And the processes in which the abrasive is sprayed in the form of a mixed fluid with compressed air or the like, such as those known as sand blasting and bead blasting; and in addition, the term includes wherein the projection material is sprayed, abrasive or projected by centrifugal force. The material is ejected by hitting a rotating impeller and the like. Further, according to the above-described mouth sand process, in addition to the abrasive grains and other abrasives used for polishing or cutting purposes, the abrasive of the present invention also broadly includes so-called "shear" which is sprayed for the purpose of imparting residual stress to the workpiece. Such as steel balls, glass beads/plastic knee beads/ceramic beads, and the like, and powder or particulate matter, such as seed shells or seed cores that are ejected for various other purposes. [Prior Art] Various fields A use the sandblasting method of spraying powder or particulate matter on a workpiece. For example, the process of cutting or cleaning a workpiece by jetting abrasive and colliding the abrasive with the workpiece, bite the mountain. Particles such as steel balls collide with the workpiece to impart residual stress to the workpiece. In the case of such a sneezing process, the % dust generated by the diffusion of the sprayed abrasive or the crushed powder generated by the collision of the abrasive with the workpiece, the powder produced by the cutting of the king piece, etc. Pollution. Because it is necessary to collect after the abrasive is used in order to recirculate the abrasive, it is common to form a working chamber that is isolated from the rest of the space and to work in this space. In addition, during painting, sprayed by a sprayer or the like; the diffusion of the paint particles or the evaporation of the solvent contained in the paint may cause pollution to the surrounding environment, and at the same time, if it is, such as dust Particles and other impurities from the surrounding% into the human workspace and adhere to the paint, the quality of the paint will be greatly reduced. Therefore, in order to prevent the above, a working chamber isolated from the rest of the space is formed, and a painting step is performed in this working space. In the above-mentioned sandblasting process as a step before painting, it has also been proposed to construct a device which can be subjected to a painting step after the sandblasting process. As an embodiment of an apparatus capable of painting a gas container such as an LP gas, it is also proposed to carry out a spray after re-inspecting the container and further removing the stain. a sand processing chamber and a chamber for painting, and constructed such that the workpiece of the conveyor or the like is subjected to a sandblasting process, the workpiece is passed through a sandblasting process chamber, and after being conveyed to the painting chamber Painting (Japanese Unexamined Patent Publication No. H08-28793). ^ As in the above '28793, if the workpiece to be processed is relatively small, has the same shape of 201105462, and requires I^ π & to be treated the same, such as LP cylinder, respectively, to provide a chamber for the process and for coating It is relatively easy to carry out such processes by lacquering the chambers and by transporting the guards to different small steps. ^ If, for example, the workpiece is large and the article is manufactured on a small scale, the material or shape of the workpiece to be processed and the details of the process are often different in each process: workers often do not fit on the assembly line such as the conveyor described above by ' Each workpiece of the normalized flow process is manually processed. : This is required when working on the workpiece to be processed. 2 Workpieces - Starting and working with a relatively large work space: Unique:: Studio. Therefore, if it is necessary to separately provide a large installation space for the sandblasting process and painting, and prepare for each system, the sandblasting process is suitable for the sandblasting process suitable for the large workpiece: the sandblasting process is carried out, and Painted by a painter with the right to apply or cooperate with the collaborators, the two teas are carried out in a collaborative manner. =Guang Zuo is supplied in different ways in different ways in this way. From: Each work step must carry/transfer the workpiece, resulting in a related time loss or financial burden. Thousands of doors:: If the handling or transfer time between the sandblasting process and the painting is long, it may cause contamination on the surface of the workpiece, and 2: the pollutants of the oil wax or its analogue may also Will be in contact between the two workpieces and workers, conveyors, etc.: turn; When contaminating or adhering to contaminants in this way, it is necessary to remove contamination or contaminants before = 6 201105462. According to the above, when the pretreatment of the large work is carried out, it is advantageous if the spray has been carried out after the process has been carried out in the same working chamber as the pre-painting process. Paint without the need to move or transfer the workpiece, = two abrasives for the sandblasting process or a sandblasting process in the sandblasting process, and therefore, if no work is taken in this work Or the dust may be painted as an impurity 7, which will greatly reduce the quality of the paint: 1::. The viscosity of the impurities is repeatedly painted. ^• In some cases, it may be necessary to 'when collecting and re-grinding the abrasives sprayed in the studio, if the m paint is contaminated, then the adhesion between the particles due to the paint may occur. It may not be possible to collect the circulating abrasive after using the abrasive. In addition, because during the sandblasting process and painting, the interior of the studio is diffused by the atomized paint, or the 纟* _ wide doubles are fine H, so it is necessary to make the studio ventilate and keep clean. The dust or fine particles (which are contaminated by the bow) are removed from the paint before the polluted air is discharged. The fact is common to the studio where the sandblasting process and painting are carried out. ...and 'the contamination in the working space during the sandblasting process is caused by the dust consisting of the powder produced by the crushing mill or the knife "workpiece, and in addition, the pollution in the working space during painting is caused by spraying It is caused by the granules of the sprayed spray paint, because the substances causing the pollution are different as described above, 201105462
所以適於通風4L方法及捕寺足造成肖染的⑼質的$法在喷砂 製程與塗漆之間是不同的。 V 因為以上幾點，所以喷砂製程及塗漆不在同一工作室 中進行，且另外，尚未提出經建構以使得能夠進行喷砂製 程與塗漆兩者的工作室。 已設想出本發明來克服上述習知技術中的問題，且使 用本發明，有可此在同一工作室中依序進行喷砂製程及塗 漆因此，本發明的一目標在於提供一種能夠藉由適合通

間l〇a中所喷射的磨料或粉塵（諸如磨塵及喷砂製程所產生 的磨料的碎粉末）以便將其向下推至底板16側的向下氣 流；因此’由於磨料或粉塵懸浮導致的污染可在早期得到 解決。磨料或粉塵不易黏著於頂板1 5或側壁11至14等， 且因此’亦防止已黏著於所述位置的磨料或粉塵落在油漆 塗料上並在後續塗漆期間與其黏著所導致的有害影響。 另外’藉由設置集塵單元20的進入風速以使得通風管 道10b中的風速小於磨料的懸浮速度，可在藉由集塵單元 20進行通風期間防止磨料吸入集塵單元20中，且可單獨收 集並再循環磨料。 另外’藉由在塗漆期間打開入口 11 a時使用通風單元 11 201105462 3〇進行通風’且如圖3中所示，在塗漆期間，藉由產生自 圆t的左側向右側在工作空間1〇a中流動的氣流，可使油漆 粒子在工作工間1 〇a中移動相對較長的距離；油漆粒子將在 此期間變乾，且易於捕捉通風單元3〇中的油漆粒子。 另外，藉由在打開入口 lla時進行通風，大量空氣引入 工作空間10a中且使工作空間1〇a之内部保持潔淨且衛生的 環境。 因此，即使當喷砂製程與塗漆皆藉由使用單個工作室 進行時，亦可在喷砂製程及塗漆期間進行最佳通風。 藉由用集塵單元20或通風單元3〇中的任一者（在具 體實例為集塵單元20)形成以突出方式配置於主單元中 的上述分隔壁25，與集塵單元2〇與通風單元3〇皆配置於 主單元10外部的情況相比，工作室丨整體上可建構成更緊 凑。 、 此處，當在所說明的具體實例中在塗漆期間藉由通風 30經由提供於另一側壁丨2中的開口 12a進行通風時， 元 單 如圖3中的白色箭頭所示，因為來自卫作空間1〇a的氣流在 引入集塵單元20的進入口 22側之前經由開口 12a引入至通 風單元30側，所以使得油漆粒子難以引入集塵單元2〇側 中，即使當在打開集塵單元2G的進人σ 22的同時藉由通 風單元3 0進行通風時亦為如此。 另一方面，當在噴砂製程期間藉由集塵單元2〇進行通 風時，如ffi 1中的白色箭頭所示，因為工作空間心中的空 氣引入通風管道10b中且隨後在氣流與另一側壁12碰撞並 12 201105462 受該另一側壁12偏轉後引入進入口 22中，所以若在打開

内部的空氣且將其排出至主單元1〇外部；由此，如圖1中 的箭頭所示’經由提供於主單元10的頂板15上的吸氣孔 17將外部空氣向下引入已由於此集塵單元2〇施加的抽吸而 產生負壓的工作空間l〇a中。 將工作空間1 〇a内部的空氣自主單元丨〇的底板丨6與分 隔壁25的下端25a之間的間距經由通風管道1〇b吸入集塵 單元20的進入口 22中，且在集塵單元2〇中移除空氣中所 含的粉塵後排出潔淨空氣。 在此具體實例中，作為提供於集塵單元2〇中的排氣通 風機21，使用具有能夠產生使得能夠每分鐘排出主單元⑺ 中空間容積h5倍的空氣體積的空氣流量率的能力的排氣 通風機作為一實例，且因此，可立即移除喷砂製程所產生 的柘塵等，且使工作空間i 〇a保持潔淨及舒適。 因為經由形成於頂板15中的吸氣孔17達成將外部空 氣引入工作空間1〇a，且以此方式經由在接近底板16的位 置處所形成的通風管道l0b達成抽吸工作空間1〇a内部的空 虱，所以如圖1中的箭頭所示，在工作空間i〇a中產生自頂 板丨5導向底板16的向下氣流。 因此’所喷射的磨料及在喷砂製程期間所產生的粉塵 23 201105462 移動，以便由此齑泠妞& + , ' 向底板16且落下並在相對較短的時 間内沈積於底板16上. _ ’因此’一旦落下的磨料、粉塵等沈 積於底板16上，則並τ p姑，

間l〇a中通風單元30所產生的氣流吹動，且因此，即使當 入口 11 a保持打開時’油漆粒子亦不會藉由產生導向開口 12a側的氣流而自入口 1 ia洩漏至主單元1〇外部。另外， 油漆粒子與此氣流一起藉由在到達底板16之前通過工作空 間10a及通風管道1 〇b而經由開口 12a吸入通風單元3〇中 且由上述擋板32a及二次過濾器32b捕捉，並將潔淨空氣排 出至外部。 此外’油漆粒子傾向於在移動時變乾，因為油漆粒子 25 201105462 在工作空間1 〇a中自入口 11 a側至開口 12a側移動相對長的 距離’且因此，通風單元3 0的捕捉效率得到提高。 另外，如上文所述，因為在工作空間1 〇a中產生自入口 11 a侧流動至開口 i 2a側的氣流，所以即使尚未收集的磨料 及粉塵等殘留於底板16上，磨料及粉塵亦會沿底板丨6移 動且不易被向上吹動。因此，可防止油漆塗料受磨料及粉 塵污染。 特疋5之，因為通風單元30中所提供的排氣通風機31 的進入空氣流量率設置為大於例如集塵單元2〇中所提供的 排氣通風機21的進入空氣流量率的2至7倍，所以可藉由 引入大量外部空氣而使工作空間1〇a保持潔淨並防止油漆 粒子經由入口 lla洩漏。另外，更可靠地將油漆粒子引入通 風單元3 0中而不使其到達底板16變得可能。 第一具體實例

painting. V Because of the above points, the sandblasting process and painting are not carried out in the same working chamber, and in addition, a working chamber constructed to enable both sandblasting and painting has not been proposed. The present invention has been conceived to overcome the problems of the prior art described above, and with the present invention, it is possible to sequentially perform sandblasting processes and painting in the same working chamber. Therefore, it is an object of the present invention to provide a Suitable for ventilation methods and methods suitable for capturing contaminated materials at each step of the sandblasting process and painting to achieve a ventilated blasting chamber, thus allowing painting in the same space after the blasting process. SUMMARY OF THE INVENTION The outline of the present invention and the reference numerals used in the [Embodiment] will be described below. The reference numerals are used to clarify the correspondence between the description in the [Application Patent Scope] and the description in the [Embodiment], and of course, it is not intended to explain the technique of the invention in a limited manner. Fan mouth. In order to achieve the above object, the blasting chamber 1 of the present invention comprises: a main unit 10; a dust collecting unit 20; and a ventilating unit 30, wherein the main unit 10 defines a space having a rectangular shape or the like using the side walls π to 14, the top plate 15, and the bottom plate 16. , 8 201105462 出出介 / 1G任—The side wall 11 is provided with an opening/closing part nb that allows the guard to enter and exit the entrance, the author M enters and leaves the chamber, and opens/closes θ a a door or a door, etc., providing a partition wall 25 configured to be on the main unit side (four) from the top side of the other side wall 12 to the bottom plate 16 from the top plate 15 so that the lower wall 25 of the wall 25 can be at a predetermined height The position is separated from the bottom plate μ, and the working space 1〇a is formed between the one side wall 11 and the partition wall 2〇 by separating the space in the main unit 1〇 by the partition wall 25, and the partition wall 20 and the other A ventilation duct 10b is formed between the side walls 12, and a lower end side thereof communicates with the working space 1a, and a plurality of suction holes 17 are formed in the top (four) above the working space 1A, which introduces outside air into the working space. a, the dust collection unit 20 and the ventilation unit 3 and the ventilation duct i〇b The dust collecting unit 20 is operated during the blasting operation, and is arranged such that the entering wind speed in the venting duct H)b is smaller than the levitation speed of the abrasive used in the maximum amount and the dust suspended in the main unit 10 and the main The air in the unit 1〇, and the clean air is discharged after capturing the dust in the air, and the j wind unit 30 sucks the paint particles suspended in the main unit 10 and the main unit 1 during the painting step (4). The air in the air, and the clean air from which the paint particles have been removed after capturing the paint particles in the air" is configured by the dust collecting unit 20 or the ventilation unit 30 in the blasting chamber of the above configuration (in In the specific example, the dust collecting unit 20) so that 201105462 protrudes in the main unit i to form the partition wall 25, and on the surface of the partition wall 25 opposite to the other side wall 12, a dust collecting unit or ventilation constituting the partition wall 25 is formed. The inlet port of unit 3 (in the specific example, the inlet port 22 for dust collection). . An other side wall 12 can have an opening 12a formed therein that is between the dust collection: the other of the ventilation units 30 (in the specific example, the venting soap το 30) and the ventilation duct 1 〇 b Connected. Preferably, the intake air passing through the dust collecting unit 2 per minute flows to or is 15 times larger than the volume of the main unit 10. Further, preferably, the air flow rate by the ventilation unit 3 is equal to or greater than 0. 4 m/s, and /3 deg. 2 Preferably, the incoming air flow rate through the venting unit 30 is 2 to 7 pieces through the inlet air flow rate of the early enthalpy 20. And an abrasive collecting unit 40, which is composed of 1: the abrasive collecting pipe, the end is on any side wall of the main single raft 10 (in the specific example, the lower end position of the side wall (1) leads to the working space... The cyclone has its inlet port communicating with the other end of the collecting pipe 41; and the exhaust pipe 43, the rising end is in communication with the air outlet 42b of the cyclone 42, H)b, 2b is connected and the other end is allowed with the air duct a second opening/closing member 44 that blocks the communication between the exhaust duct 43 and the inlet port of the dust collecting unit 2, and 4 opens/closes the ventilation duct 1 at a communication position between the dust collecting unit 2G and the ventilation unit 3Q Third opening/closing member of stream # in 〇b Μ According to the configuration of the present invention described above, during the blasting process, the 10 201105462 blasting chamber of the present invention can be used in the spraying (four) (four) „(iv) m dust collecting unit 20, by the mouth The condition of the sanding u causes the dust collecting unit 20 to open the inlet during the painting and closes the mountain and operates to ventilate and capture the dust. The ventilation unit 30 is used to cook and capture the paint particles, and thus the method & 丨 also 1 U for sandblasting process and painting Further, the same working chamber 1 β is used. Further, according to the configuration of the above-described work 胄 1, during the blasting process performed when the inlet 11a is closed, the outside air is introduced through the suction holes 17 formed in the top plate 主 of the main unit 1〇. In the chamber i, and at a relatively low position between the lower end 25a of the partition wall 25 and the bottom plate 16, suction is applied to the working space 1A via the ventilation duct 10b communicating with the working space 10a, such as = As shown in Fig. 1 of the example, abrasives or dust (such as dust and abrasives generated by the sandblasting process) sprayed in the working space l〇a are generated in the work ti to push it down to Downward airflow on the side of the bottom plate 16; therefore 'contamination due to abrasive or dust suspension can be solved at an early stage. Abrasives or dust are not easily adhered to the top plate 15 or the side walls 11 to 14, etc., and therefore 'also prevent adhesion to the said The position of the abrasive or dust falls on the paint and the harmful effects caused by the adhesion during the subsequent painting. In addition, by setting the inlet wind speed of the dust collection unit 20, the wind speed in the ventilation duct 10b is made smaller than The suspending speed of the material can prevent the abrasive from being sucked into the dust collecting unit 20 during the ventilation by the dust collecting unit 20, and the abrasive can be collected and recycled separately. In addition, the ventilation unit is used by opening the inlet 11a during painting. 11 201105462 3〇 Ventilation' and as shown in Figure 3, paint particles can be placed in the work space during the painting by creating a flow of air flowing from the left side of the circle t to the right side in the workspace 1〇a The 〇a moves a relatively long distance; the paint particles will dry out during this time, and it is easy to catch the paint particles in the ventilating unit 3. In addition, a large amount of air is introduced into the work space 10a by ventilating when opening the inlet 11a. And keep the interior of the workspace 1〇a clean and hygienic. Therefore, even when the blasting process and painting are performed by using a single working chamber, optimum ventilation can be performed during the blasting process and painting. Forming the partition wall 25 disposed in the main unit in a protruding manner by using any one of the dust collecting unit 20 or the ventilation unit 3 (in the specific example, the dust collecting unit 20), and ventilating the dust collecting unit 2 Compared with the case where the units 3 are all disposed outside the main unit 10, the working chamber can be constructed to be more compact as a whole. Here, when ventilating by the ventilation 30 through the opening 12a provided in the other side wall 丨2 during painting in the illustrated embodiment, the order is as indicated by the white arrow in FIG. 3 because The airflow of the guard space 1〇a is introduced to the side of the ventilation unit 30 via the opening 12a before being introduced into the inlet port 22 side of the dust collecting unit 20, so that it is difficult to introduce the paint particles into the side of the dust collecting unit 2 even when the dust collection is turned on. This is also the case when the unit 2G is ventilated by the ventilation unit 30 while being in the σ 22 . On the other hand, when ventilating by the dust collecting unit 2 在 during the blasting process, as indicated by the white arrow in the ffi 1, since the air in the working space is introduced into the venting duct 10b and then in the airflow and the other side wall 12 The collision and 12 201105462 are introduced into the inlet port 22 after being deflected by the other side wall 12, so if the ventilation is provided while opening the opening 12a provided in the other side wall 12, the dust contained in the airflow passes through the opening i 2a and The catching member Μ of the ventilating unit 3 (such as the baffle 32a, the secondary filter 32b, etc.) collides, and thus the filter life of the catching member 32 may be shortened. However, by providing the first opening/closing member 12b (in the specific example, the cover for opening and closing the opening 12a) for opening and closing the opening 12& as described above, when by the dust collecting unit 2 When the venting is performed, the opening 12a is closed by using the opening/closing structure #(3) without introducing dust into the ventilating sheet 7G 30' and thus, the catching member 32 provided in the ventilating unit 3A as described above is prevented. The filtering function (such as a support plate, a secondary passer (10), etc.) is lowered. It is not possible to provide a slamming during the ventilation at the inlet 22 of the inlet 20 of the dust collection unit 20 by the venting unit 30. However, in the illustrated configuration, the paint particles 22 are completely prevented during venting, Therefore, it is preferable to open/close the member in the dust collecting unit, and to pass through the inlet port 22 of the ventilation unit. In the position where the dust collecting unit 2〇 and the saponin 3〇 are reversed from the specific example described, if it is right Η. . 19h aI . ^ Providing the first opening/closing member 1 2b ' at 12a, the air is introduced into the dust collecting soap το 20 during the ventilation by the ventilation unit, and the life of the lit "dust" 20 is shortened. And the opening/closing member for opening and closing the inlet port thereof is provided on the side of the ==2 unit. The inlet air flow rate is set by the 隼" dust year 7L 20 per minute. 13 201105462 is equal to or greater than the main The K5 of the volume of the unit 10 can be ventilated and kept clean even if the dust or the like produces a 'work space 1 〇a' in a relatively short period of time. Μ, in the configuration in which the paint particle capturing member 32 provided in the ventilation unit 30 is equipped with the baffle 32a, since the paint particles are captured by colliding with the baffle 32&, as in the case of filtering out particles, There is a problem that the entering wind speed is lowered due to the clogging, and therefore, the ventilation can be maintained for a long time. "In addition, since the paint particles are captured by the dry method using the baffle 32a, it is not necessary to perform a method such as a wet capture method (that is, a method of capturing paint particles by passing the discharged gas through water collected in the water tank). I Handling complex work such as wastewater, and maintenance can be performed using the relative | work of the replacement baffle. 91 In addition, the airflow speed set by the ventilation unit 3〇 in the work space 1〇a is equal to or greater than 〇·4 _ or the inlet air flow rate through the ventilating unit 30 is set to enter through the dust collecting unit 2〇: 2 to 7 times the air flow rate, even when the inlet 11a is opened, the paint particles are prevented From the entrance Ua to the outside of the work "1 10a: In addition, by introducing a large amount of outside air into the heart of the workspace: 2 The interior of the heart is kept clean. By transferring the paint with this gas stream: 'The paint particles can be more reliably introduced into the venting unit 30 and captured on the landing panel 16 and adhered thereto. The sore is additionally 'in the configuration providing the collecting unit and providing the second opening " the third opening/closing member 45, f member = 14 201105462 The communication between the xenon b channel 43 and the inlet port 22 of the dust collecting unit 2〇, and opening The closing member 45 is sealed under the inlet port 22 of the dust collecting unit 20: a flow path of two:. At the same time, by operating the dust collecting unit 2, the suction pipe is applied to the working space by "receiving the four pipes (10), the exhaust pipe 43, the cyclone 42 and the collecting lane 4i. And, therefore, the broom or the like cleans the abrasive and dust on the bottom plate 16 to collect the abrasive and dust in the space 10a and into the opening portion of the collecting duct. The abrasive to be recycled is collected by the cyclone 42. Further, by extending the collecting duct 41 by connecting the hose 47 for collecting the abrasive to the opening portion of the collecting duct 41, the abrasive collecting hose Ο can be moved to the appropriate position in the working space 1〇a. Suction of the bottom plate (7) ... or dust / · Therefore, the worker M does not have to perform the work of cleaning the abrasive or dust located on the bottom plate 16 like the above-mentioned work = with a broom or the like. In a configuration in which an abrasive collecting space 62 is formed between the bottom plate 16 and the perforated plate 61, a collecting unit 40 including a dust collector 5A equipped with an exhaust fan 51 is provided, and a closed perforated plate is provided during the painting step. The opening member 63 of the opening can simultaneously perform abrasive collection by the exhaust fan 51 using the dust collector 5G in the collecting (four) 62 and the space for the cleaning by the dust collecting unit 2G 1Qa is ventilated and allows workspace 10a to remain even cleaner. In addition, by using the closing member 63 to close the opening in the perforated plate 6 2 during painting, paint particles can be prevented from entering the collection space 62 and the abrasive is prevented from being contaminated by the paint: even when the abrasive or dust remains in the collection space 62 15 201105462 Properly prevent this abrasive or dust from being blown up and contaminate the paint. [Embodiment] The objects and advantages of the present invention will become apparent from the following description of the invention. The blasting chamber 1 of the present invention will be described below with reference to the drawings. First Specific Example Overall Configuration Reference numeral 1 in Figs. 1 to 3 is a blasting chamber of the present invention. As shown in FIGS. 1 and 2, although the overall shape thereof is not particularly limited, the working chamber 1 is manufactured so that the worker can enter and work with the workpiece w, and the working chamber 1 is provided with the side walls 11 to i4. a substantially box-shaped main unit 10 surrounded by the top plate 15 and the bottom plate 16; a dust collecting unit 20 for ventilating the main unit ι during the blasting process; and a venting unit 30 for ventilating the main unit ι during painting . Main unit The main unit 1 constituting the working chamber 1 of the present invention is a box-shaped chamber made of, for example, metal and is formed by two pairs of opposing side walls (11 and 12 and 13 and 14), a top plate 15, and a bottom plate 16. The main unit 1 is formed on a top plate 15 of the main unit 10 with a working space that the worker μ can enter with the workpiece w for sandblasting and painting, preferably evenly and at equal intervals. A plurality of suction holes 17 for introducing outside air into the working space 10a of the main unit 10 are provided on the top plate 15 above the space 10a. When the ventilation is performed by the dust collecting unit 20 and the paint exhaust unit 30 described below and suction is applied to the space inside the main unit 10, the outside air is lowered downward through the above-mentioned suction 16 201105462 hole 17 provided on the top plate 15. Introducing the main unit ίο in addition, the two pairs of opposing side walls u and 12 and ΐ3 and a pair of (n and 12) side walls u are provided to allow the workpiece to be moved in and allow the worker to enter and the door to stay - " To harden and hit the door and doorman + leave the main saponin 1 〇 entrance lla. Provide J q for opening and closing this inlet 1 1. etc. la open 'closed part lib, which is the door or the door is different' The other side wall 丨 2 opposite to the side wall by the ventilating unit absorbing unit 11 is provided with an opening 1 2a, and 3 〇 is applied to the main unit 1 through the opening 12a. The opening 12a is provided with a first opening/closing member m. As a cover for opening and closing the opening 12a, and using this first opening/closing member (3), the opening can be closed during the blasting process... and the opening 12a can be opened during painting. In the illustrated embodiment, Although the ventilation unit 30 is connected via this opening 12a, Instead of this configuration, the opening i 2a may be provided to communicate with the dust collecting unit 20 described below, and the configuration of the dust collecting unit 20 and the ventilation unit 30 may be reversed from the illustrated configuration. In the above-described main unit 10, provided closer to the above The other side wall 12 is disposed at a position so as to protrude from the top plate 15 toward the bottom plate 16 such that the lower end 25a is located at the partition wall 25 at a predetermined high position with a spacing from the bottom plate 6. As shown in Fig. 2, this partition wall 25 The width corresponds to the distance between the side walls η and 14 arranged perpendicular to the side wall 11 on which the inlet 1 la is provided, and the space in the main unit 10 is separated by the partition wall 25. In the main unit 1 17 17 201105462 The side wall side of the knife partition wall 25 forms a working space i〇a that the worker Μ enters with the workpiece w and the worker Μ works inside, and forms a lower end and the working space 10a on the other side wall 12 side of the partition wall 25. Connected ventilation duct 10b. As shown in Figs. 1 and 3, the lower end portion of the other side wall 12 of the main unit is inclined so as to approach the working space l〇a in the downward direction, and when ventilated by the dust collecting unit 20 described below Unit 3 is now When suction is applied in the air duct 1〇1), the airflow flowing into the ventilation duct 10b from the working space l〇a side can be smoothly introduced into the ventilation duct 10b. In the illustrated specific example, by forming the following The dust collecting unit 2 is formed to form the partition wall 25 so as to protrude into the main unit 1〇, and the partition wall 25 also serves as an outer casing of the dust collecting unit 2〇. Therefore, the assembly of the dust collecting unit 2〇 (such as a filter (Fig. It is accommodated in the wall thickness of the partition wall 25. In the illustrated specific example, although the partition wall 25' is formed by the outer casing of the dust collecting unit 20, the partition wall 25 and the dust collecting unit 20 can be completely formed independently. And, for example, the ventilation duct 10b may communicate with an opening formed on a side wall of the main unit 10. Further, instead of the illustrated configuration, the dust collecting unit 20 and the ventilation unit 30 may be arranged upside down as described above, and the partition wall 25 may be formed by the ventilation unit 30 so as to protrude into the main unit 10. A perforated plate (not shown), preferably a relatively thick perforated plate (such as a grid or the like), may be placed on the bottom plate 16 of the main unit 10 so that the sandblasting that has fallen and reaches the bottom plate 16 The abrasive sprayed during the process or by the dust generated by the jet abrasive is trapped in the opening formed in the porous plate, thereby easily preventing its resuspension and the like. In this case 3, the porous plate can be simply placed on the bottom plate 16 so that it can be easily removed; and during the abrasive collection, the porous plate can be removed from the bottom plate 16, and the abrasive deposited on the bottom plate ί6 can be It is collected by, for example, sweeping with a broom or the like. Dust cover 亓. The main unit 1 如上 constructed as above has a dust collecting unit 2 that performs ventilation of the main unit 10 during the blasting process. ...the dust collection is sucked by the exhaust ventilator 21 provided in the dust collecting unit 20 via the above-described ventilation duct 10b# and has been sucked from the work space 1〇a The air is exhausted from the dust by the internally provided dust catching member (not shown) such as a filter or the like. As described above, in the illustrated specific example, by arranging the dust collecting unit 20 in the main unit in such a manner as to protrude from the side of the top plate 15, the outer casing of the dust collecting unit 2 is also used as shown in FIG. As the partition wall of the outer wall of the dust collecting unit 2〇, the inlet side 22 is provided on the side of the side, and by the air ventilator 2!, through the ventilation duct, which will be the internal air* The introduction of the port 22 into the dust collection unit 2 is not provided in the illustrated construction, but it is preferred to provide the following opening during the ventilation by the dust collection 7C 20 -_Λ ^ and by ventilation 30 An opening/closing member that closes the inlet port 22 during ventilation, such as 19 201105462 cover or the like. - again, the exhaust fan 2 provided in the dust collection unit 70 20 is such that the inlet wind speed in the ventilation duct H)b does not exceed the suspension speed of the abrasive used (in other words, 'not equal to or greater than the suspension speed), so as not to pass through Ventilation pipe (10) When the working space 1Ga is ventilated, the abrasive deposited on the bottom plate 16 of the working space 1Ga is sucked into the dust collecting unit 2G; (10) preferably uses a working amount of 1. An exhaust fan with a 5x or higher inlet air flow rate to ventilate the workspace 1〇a in a relatively short period of time. Ventilation unit FIG. 3 and FIG. 4 are reference numerals for a ventilation unit that vents the main unit 10 during painting; the ventilation unit is connected to the main unit 1 via an opening σ 12a provided on the other side wall 12 of the main unit The ventilation duct in the crucible is connected and the air in the working space 1〇a is sucked through the ventilation duct 10b. The ventilation unit 30 sucks the air in the working space 1〇a of the main unit 10 by operating the exhaust fan 3丨, and introduces the air into the catching member 32 for capturing the paint particles contained in the air to capture the air. The paint particles are present in an atomized state, and the clean air is discharged. In this specific example, a baffle (primary filter) mountain and a secondary filter 32b disposed downstream of the so-called deck 32 & are provided as the above-described catching member 32 for capturing paint particles. In these assemblies, the baffle 32a is a plate that is erected in the middle of the airflow path as shown in FIG. In this specific example, the baffles 32a having a substantially U-shaped cross section disposed in the width direction are alternately engaged with each other in opposite directions so as to be illustrated by arrows in the air flow as in the figure. The meandering manner of 201105462 passes through the gap formed between the baffles 32a, causing the paint particles to collide with the surface of the baffle 32a to capture most of the paint particles in the air. By the one-way filter arranged downstream of the baffle 32a in the suction direction of the exhaust fan 31, in addition to the amount of paint particles remaining in the air that are not captured by the baffle 32a, the secondary filter is Known types of filters, such as formed by non-woven fabrics and the like. As the above-described exhaust fan 31 provided in the ventilation unit 30, the use can be equal to or greater than 0. An exhaust fan having a flow velocity of 4 m/s, and in addition, preferably, the generated intake air flow rate is 2 to 7 times the inlet air flow rate of the exhaust fan provided in the dust collecting unit 20 described above. The exhaust fan, whereby the fine particles of the sprayed paint are sucked out before reaching the bottom surface or the like in the work space and captured by the paint exhaust unit. In this specific example, since the surface of the above-mentioned baffle 32a is specially treated to improve the capturing efficiency of the paint particles, the above-described baffle 32a is highly efficient in capturing paint particles, and by using the above-described baffles 32a and two The dual filtration system of the secondary filter 32b achieves a high capture efficiency equal to or greater than 90% for melamine paint and equal to or greater than 85% for the primer. In the configuration of this specific example of capturing the paint particles by combining the baffle 32a (which is the primary transition) with the secondary filter 32b in this manner, since most of the paint particles are captured by the baffle 32a, only a small amount of paint particles are captured. It is captured by the two under-filter 32b, and therefore, clogging of the secondary filter 32b is less likely to occur; therefore, even if the secondary filter 32b continues to be used for a relatively long period of time, the entering wind speed of the ventilating unit 30 is not lowered and is successful. Ventilation of the studio. 21 201105462 By using the dry method, please use the baffle 32a and the second pass/willing 3 2 b to capture the paint particles, / by passing the exhausted air through the wet capture method (by... In the case where the water in the water tank is caught in the water to capture the paint puller, it is used for complicated work such as capturing water, and there is an advantage that it can be maintained by replacing the baffle 32a or the secondary filter line. Work early to enter m η ^ will be provided for the blasting process by using the working chamber 1 of the present invention constructed as above, and in the case where the material of the material (4) is painted before the workpiece w is processed, The opening/closing member 11b of the main unit ^(4) of the chamber i is opened, and is to be processed =: the closing member is carried into the working space... and the working worker M, (4) the (four)/closing member enters the working space 10a. In the following description, try to make an ancient Μ Α , τ . . . The work performed on the piece w will be carried out: for example, the work can be carried out in the unmanned work space machine or its analog and the guard W-into the work space l〇a instead of the worker. The wall 7 7F ' is formed on the side of the Wit blasting process, and is formed on the side bite from the rlla by the opening/closing part Ub to prevent the abrasive or the uncle dust from leaking from the working chamber 1. Item 2:: The other side wall...Open...The first-open/closed structure "takes, the exhaust fan 2 of the dust collecting unit 2 is turned on, and the exhaust fan 3 of the insect worm is closed], the working space... Worker 22 201105462 进行 spraying by spraying an abrasive supplied by an abrasive pressurizing feeding device (not shown) from a hand held blast gun to a desired position on the surface of the workpiece w By opening the exhaust fan 21 provided in the dust collecting unit 20, the dust collecting unit 20 sucks the air inside the working space 1 〇a from the inlet port 22 via the ventilation duct 1 〇b and discharges it to the main The unit 1 is external; thus, the outside air is introduced downward through the suction holes 17 provided on the top plate 15 of the main unit 10 as shown by the arrows in the main unit 10, and the suction has been applied due to the dust collecting unit 2 In the working space l〇a where the negative pressure is generated, the distance between the bottom plate 丨6 of the air autonomous unit 内部 inside the working space 1 〇a and the lower end 25a of the partition wall 25 is sucked into the dust collecting unit via the ventilation duct 1〇b. In the inlet 22 of the 20, and removed from the air in the dust collecting unit 2 After the dust is contained, the clean air is discharged. In this specific example, as the exhaust fan 21 provided in the dust collecting unit 2, the air volume capable of generating an air volume capable of discharging the space volume h5 times in the main unit (7) per minute is used. The exhaust fan of the ability of the air flow rate is taken as an example, and therefore, the dust generated by the blasting process, etc., can be immediately removed, and the workspace i 〇a is kept clean and comfortable. Because it is formed on the top plate 15 The suction hole 17 in the middle reaches the introduction of the outside air into the working space 1〇a, and in this way, the air inside the suction working space 1〇a is reached via the ventilation duct 10b formed at the position close to the bottom plate 16, so as shown in the figure As indicated by the arrow in 1, a downward flow of air from the top plate 丨 5 to the bottom plate 16 is generated in the working space i〇a. Therefore, the injected abrasive and the dust 23 201105462 generated during the blasting process are moved, thereby齑泠妞 & + , ' to the bottom plate 16 and dropped and deposited on the bottom plate 16 in a relatively short period of time. _ ' Therefore, once the fallen abrasive, dust, or the like is deposited on the bottom plate 16, it is not easy to resuspend in the air by the upward flow of the airflow generated by the ventilation. After the blasting process has been completed, the abrasive and powder deposited on the bottom plate 16 are removed as needed, for example, by using "or its analogs" as described above. The grid is placed on the bottom plate 16, and the abrasive and dust deposited on the surface of the bottom plate 16 can be collected after temporarily removing the porous plate. «In this way, the abrasive is removed by, for example, cleaning with a broom or the like. In the case of dust, it is preferable to close the population (1) because the dust deposited on the bottom plate 16 will be resuspended during the process, and the opening/closing member 12b is kept closed, and the dust collecting unit is kept closed. The exhaust fan 21 of 20 is (maintaining the ventilation unit & % of the exhaust fan 3 1 closed) 'and continues to ventilate the working space 1 〇 a. ^ instead of performing the collection of the abrasive, for example by using a protective plate The bottom plate 16 on which the abrasive and dust are deposited (or a perforated plate such as a grill or the like) is used to prevent the dust deposited on the bottom plate from being contaminated by resuspension. Paint, I prevent oil Absorbing the abrasive deposited on the bottom plate, which will be collected and recycled later during the next step of painting. After the blasting process has been completed, the abrasive and dust deposited on the bottom plate [6] have been completed as described above. The workpiece w is painted in a state where the removal and/or the bottom plate 16 has been covered with a protective plate or the like. 24 201105462 During painting, as shown in Figure 3 (3), the opening is provided by = operation An open/closed structure # ^ M . The opening 12a of the other side wall 12 of the saponite is connected to the ventilation duct_, and the ventilation unit 3 is opened. The ventilator provided in the air ventilator 2 and the dust collection unit 2 关闭: 21, to ventilate the workspace by the ventilation unit 3〇. On the second day, 'when the opening/closing portion b provided on the (4) u of the main unit 1G is opened, the 'inlet m' is opened, and as shown by the white arrow in Fig. 3, when the air flow from the σ Iia_a 12a is generated, 'by spraying Paint is used to paint the workpiece W. As described above, when the exhaust fan 31 provided by the wind unit 3G towel is opened 'while the person π lla is opened, not only the air intake hole 17 provided on the top plate 15 is bowed into the outer space 1, but also via the iu ^ A large amount (four) of air is introduced into the work space 10a, and an air flow flowing from the left side to the right side in the drawing is generated in the work space 10a as indicated by a white arrow in FIG. Here, since the paint sprayed in the work space 10a is in a fine grain state and has a lower weight than the abrasive or the like, the paint is easily blown by the air flow generated by the ventilation unit 30 in the work space 10a, And therefore, even when the inlet 11a is kept open, the 'paint particles are not leaked from the inlet 1 ia to the outside of the main unit 1 by generating the air flow on the side of the guide opening 12a. In addition, the paint particles are taken into the ventilating unit 3 through the opening 12a and passed by the baffle 32a and the secondary filter 32b, respectively, through the working space 10a and the ventilation duct 1 〇b before reaching the bottom plate 16 and by the baffle 32a and the secondary filter 32b. Exhaust clean air to the outside. Furthermore, the 'paint particles tend to dry out when moving because the paint particles 25 201105462 move a relatively long distance from the inlet 11 a side to the opening 12 a side in the workspace 1 〇 a' and thus the capture efficiency of the ventilation unit 30 is obtained improve. Further, as described above, since the airflow flowing from the inlet 11a side to the opening i2a side is generated in the working space 1 〇a, even if the abrasive and dust which have not been collected remain on the bottom plate 16, the abrasive and the dust are also It moves along the bottom plate 6 and is not easily blown upward. Therefore, the paint coating can be prevented from being contaminated by abrasives and dust. In particular, the intake air flow rate of the exhaust fan 31 provided in the ventilation unit 30 is set to be larger than 2 to 7 of the intake air flow rate of the exhaust fan 21 provided in the dust collecting unit 2, for example. Multiple times, the workspace 1〇a can be kept clean by introducing a large amount of outside air and preventing paint particles from leaking through the inlet 11a. In addition, it is possible to more reliably introduce the paint particles into the ventilation unit 30 without causing them to reach the bottom plate 16.

The studio i of this specific example shown in Figs. 5 to 7 is provided with a receiving duct 41, The cyclone 42 and the exhaust duct 43 are constructed by a collecting unit 4: The working chamber 1 is different from the working chamber 1 of the first specific example described above with reference to Figs. i to 4 in the ventilating tube The second opening/closing member 44 and the third opening/closing member 45 are provided. The rest of the configuration is the same as that of the first to specific examples described with reference to the drawings/to, and the description of the common part is made by the internal gas. The above-mentioned collection unit 40 of the cyclone 26 201105462 re-collects the high-receiving and lowers the lower phase and the separation, and the swirling vortex is generated from the falling-off flow. The abrasive material is thus ground and the abrasive to be recycled is separated and collected by discharging the lighter dust than the abrasive gas. The lower end of the cyclone 42 may be provided with an abrasive storage tank 42c for collecting the collected abrasive. And additionally 'the cyclone 42 can be provided for The abrasive collected in this storage tank 42c is pressurized and fed to an abrasive pressurizing feeding member (not shown) or the like of the blasting gun disposed in the working space i〇a. As shown in Figs. 5 to 7 'this whirlwind The inlet 42a of the heater 42 communicates with the working space 10a via the collecting duct 41. The air outlet 42b of the cyclone 42 communicates with the above-described ventilation duct 丨〇b formed in the main unit 1 through the exhaust duct 43. The lower end of the opening portion of the collecting duct 41 leads to the working space 10a' so as to be at the same height as the bottom plate 16 of the main unit 1 , and as shown in FIG. 6, the abrasive and dust deposited on the bottom plate 16 can be used by the worker. Μ The abrasive and dust are swept into the opening portion of the collecting duct 4' using a broom or the like to be sucked into the collecting duct 41. Further, the exhaust duct 43 communicating with the air outlet 42b of the cyclone 42 is passed through the main unit 1 The top plate 15 communicates with the above-described ventilation duct 10b. In the ventilation duct 10b, the above-described second opening/closing member 44 and the third opening/closing member 45 are provided. The second opening/closing member 44 is used for opening and closing. Exhaust duct 43 and The flow path between the inlet ports 22 of the dust collection unit 20, and in this specific example, the second opening/closing member 44 of the plate member opens/closes at a position above the inlet port 22 of the dust collection unit 2A. 27 201105462 The wind duct i〇b, thereby allowing/preventing the communication between the inlet port 22 of the dust collecting unit 2〇 and the exhaust duct 43. In addition, the above-mentioned third opening/closing member is used for entry into the dust collecting unit. The flow path 'in the ventilation duct lb is opened and closed at a position where both the port 22 and the opening 12a are lower, and this third opening/closing member controls the air: flows from the working space 10a to the dust collecting unit 2'. As shown in Fig. 6, as a modified embodiment, the opening portion of the above-described collecting duct 经 is constructed such that the flexible collecting hose 47 can be connected via the joint 46 or the like. Thus, the opening portion of the collecting duct 41 can be lengthened. Extending the opening portion of the collecting duct in such a manner that the following configuration can be realized: the abrasive can be collected by moving the open end of the collecting hose 47 to a position where abrasive and dust are deposited without being deposited and deposited on the main unit. Abrasives and dust on the bottom plate 16 of the 〇. - In the case of the studio of this specific example constructed as above, the second opening/closing member 44 is disposed so as to block the communication between the exhaust duct 43 and the inlet port 22 of the dust collecting unit 2A. And a third opening/closing member is disposed to open the ventilation duct i 〇b during the blasting process. In this state, the D lla is closed, the opening (2) is closed by the first opening/closing member (3), the exhaust ventilator 21 of the dust collecting unit 2G is turned on, and the exhaust ventilator 31 of the ventilating unit 3 is closed. And the studio of the body example - the ventilation of the space of the space by the dust collection unit After the blasting process is finished, the deposited abrasive and dust are collected on the bottom plate 16 of the working space l〇a. The second opening/closing 28 201105462 is operated in Fig. 6 to connect the exhaust duct ya from the inlet port 22 of the silver, dust collecting unit 20, and to make a third open/close configuration bite kneading. To close the flow in the ventilation duct 1 Ob, at this time, the exhaust fan 21 is opened and the ventilation unit is opened by the exhaust fan 31 opening/closing member 12b of the first and holding dust collecting unit 20 30 keeping the opening 12a closed. shut down. When the first closing member 45 closes the communication between the dust collecting unit and the inlet port 22 and the working space, the field cannot directly apply suction to the work 〇a via the vent 10b. 'However, however, an inlet port of the exhaust duct 43 and the dust collecting unit 2 is formed. The communication 'and thus' dust collection unit 70 20 begins to apply suction to the workspace i〇a via the exhaust duct 43, the cyclone 42 and the collection duct 41. Therefore, when the abrasive and the private dust deposited on the bottom plate 16 are loaded into the opening portion of the collecting duct 41, the loaded abrasive and dust are separated from the air inside the working space 1〇a. Introduced into the cyclone 42 together. The contained abrasive is removed and collected by the vortex flow generated in the cyclone 42 and collected in a sump provided below the cyclone 42. In one aspect, the air containing the dust from which the abrasive has been removed and collected is introduced into the exhaust duct 43 through the air outlet 42b of the cyclone 42, and introduced into the dust collecting unit 20 via the vent duct 10b. Further, dust is removed in this dust collecting unit 20 and clean air is discharged to the outside. After finishing the collection of the abrasive in this manner, when the workpiece w 29 201105462 is painted after the blasting process, as shown in FIG. 7, the second opening/closing member 44 is disposed to close the exhaust duct 43 and the dust collecting unit 2 The communication between the inlet ports 22 of the crucible and the third opening/closing member 45 are disposed to open the ventilation ducts 1B. Further, the opening i2a which has been closed by the first opening/closing member 12b is opened and the inlet 11a is opened, and the exhaust fan 2i of the dust collecting unit 2〇 is also closed, and the exhaust fan 3 of the ventilation unit 3G is turned on. Thereby, the ventilation of the work space 10a is successfully performed during painting, as in the first specific example described with reference to FIG. Then, the sprayed paint particles are captured by the baffle 32a and the secondary filter 32b provided in the ventilation unit 3G, and the clean air is discharged. As described above, it is easy to provide the above-described collecting single force 40 and the first opening/closing member 44 and the third opening/closing member & by the use of the negative pressure generated by the dust collecting unit 20 in this specific example. Remove the work: l(a) material and dust deposited on the bottom plate 6 of the l〇a, relatively easily collect another:: the recyclable abrasive contained, and the other discharge is removed by the dust collecting unit 2〇 Abrasive dust in the air. ', the third specific example, as described above, in the specific examples of the fourth and seventh (4), in the specific examples, the dust collecting unit 2 〇, s, s forced 1 〇 b to make the work space 1 〇a Fu = and '_ Μ unit 4 〇 collection of abrasives can be alternately collected by the abrasive can be used with the above-mentioned dust collection unit 2. The two winds are simultaneously carried out. The wind two 〇a〇a made! = specific examples, reference circle 8 and FIG. 9 depict an embodiment configuration constructed in this manner to 1. 30 201105462 In the specific example illustrated in FIGS. 8 and 9, in addition to the collection duct 41, = Fengyi 42' and the exhaust duct In addition, the collecting unit 4〇 also has a dust collector 50 equipped with an exhaust fan 51, and the exhaust duct 43 communicates with the inlet port of the dust collector 5〇. By the porous plate at a predetermined interval 61 (such as a grid or the like) is placed on the bottom plate 16 of the main sheet 70 10 to form a collecting space 62 for capturing abrasive and dust falling between the bottom plate 16 and the perforated plate 61. β is in the circle 8 and in FIG. In the configuration of the specific example studio shown, no corresponding to the second specific example studio ι described with reference to FIGS. 5 to 7 is provided. The pipe l〇b_ provides the second opening/closing member 44 and the third opening/closing member 45. In this configuration, the concrete (4) turf chamber 丨+, in the blasting process • s as a circle 8 No, the opening is closed by the first opening/closing member (10) to simultaneously open the exhaust of the exhaust fan 21 and the dust collector 5Q of the dust collecting sheet 2G, and the exhaust fan of the venting grass 3〇 is closed; Therefore, the air which is suspended inside the space 1Ga is ventilated by the air passages (10) by floating the air passages (10). The abrasive collected in the collecting space 62 is the negative pressure generated by the dust collector. The bucks-lambda opening falls on the bottom plate 16 from the perforated plate 61 to the collecting unit 40, and the abrasive is collected in the cyclone 42 collecting the early 7L 40. The air containing the ancient P + in & φ Α dust having collected abrasive is introduced into the dust through the exhaust duct 43. The dust is extracted by the dust collector 5Q and the clean air from which the dust has been removed is discharged to the outside. On the other hand, in the painting period B, the porous plate 61 is covered by, for example, a protective sheet or the like 31 201105462 in order to prevent the paint particles from entering the collecting space 62 to separate the working space 10a from the collecting space 62. Next, the opening 12a is closed by the first opening/closing member 12b, while the exhaust fan 21 of the dust collecting unit 2〇 and the exhaust fan 51 of the dust collector 5〇 are closed, and the exhaust ventilation of the ventilation unit 3〇 is turned on. The machine 3 is thus ventilated by the ventilation unit as appropriate, as described in the first and second specific examples. In the above description, although the workspace 1A and the collection space 62 are described as being separated by covering the perforated plate 61 with a protective plate, < The two spaces can be constructed to be separated, for example, by providing a door-like member that slides under the perforated plate 61, and in addition, the separation of the two spaces can be automatically performed. In the case of the working chamber 1 of this specific example constructed as above, it is not necessary to provide a step for removing and collecting the abrasive of the working space 1Qa t after changing from the blasting process to painting, which is advantageous because Painting is carried out immediately after the blasting process, which further shortens the processing time. Further, since the abrasive and dust deposited on the bottom plate i 6 are appropriately collected during the sand blasting process, it is easier to prevent contamination in the working space 10a due to the resuspension of the abrasive and dust deposited on the bottom plate 16. Although the details are omitted, the efficiency of the abrasive and dust collection can be improved by providing the abrasive collecting mechanism in the collecting space 62 t without hindering the reduction in the height of the bottom plate. This has been disclosed in Japanese Unexamined Patent Publication No. Hei. The slinger pulls out, wherein the bottom plate is divided into mesh parts through which the abrasive can pass, and a plurality of substantially inverted quadrangular pyramid funnels are arranged linearly below the cut and chamber H mesh members having the I mesh member as the bottom surface, so that The top portion 32 201105462 is opened to face the screen member, and the lower end of each funnel is connected via a collecting suction member (not shown) such as a dust collector or the like.
