Description

The present invention, electrical equipment including OA equipment, in particular to Brighter cycle processing apparatus by the dry resin molding which is used in household electric appliances.

  FIG. 6 is a flowchart showing a process of a wet recycling method, which is a conventional method for reusing a waste resin molded product.

  In step 1 (hereinafter, step is referred to as STP), after the waste resin molded product is carried in, the assembled parts are checked and removed, and further sorted by material. In STP2, the waste resin molded product is crushed into a crushed resin having a predetermined size and shape. The crushing uses a known crushing device such as crushing between two rotating blades rotating so as to mesh with each other.

  Next, in STP3, the crushed resin is put into a cleaning device and cleaned using a cleaning liquid. Cleaning is performed using a known cleaning device such as a stirring type cleaning device or an ultrasonic cleaning device. The cleaning liquid and the crushed resin are mixed and stirred in the cleaning tank, and the contaminants including the dirt, the altered layer, and the deposits on the surface of the crushed resin are removed by the cleaning power of the cleaning liquid.

  In STP4, the crushing resin to be reused is separated from the finely crushed pieces and dirt components that are generated during crushing and are difficult to reuse. The separation is performed through a sieving apparatus having a predetermined sieve, including the cleaning liquid, crushed resin, finely crushed pieces, and dirt components in the cleaning tank.

  By the sieving, the crushed resin having a predetermined size to be recovered remains on the sieve, and the cleaning liquid, the crushed resin having a predetermined size or less, the finely crushed pieces, and the soil components are separated by passing through the sieve. In general, the size of the sieve of the sieving apparatus is generally set so that the size of the crushed resin recovered in STP5 is about 10 mm square.

  Furthermore, the solid substance consisting of a pulverized resin and finely pulverized pieces having a predetermined size or less and the cleaning waste liquid containing the soil components are separated, and are subjected to a treatment for environmental protection and then discarded. In particular, the disposal of cleaning liquids that are often strongly acidic or strongly alkaline has a large environmental load, so it is important to consider reducing the load such as neutralization and dilution.

  In ST6, the crushed resin thus separated is rinsed.

  When the rinse cleaning is completed in ST6, the crushed resin is dried in ST7. Drying is generally heat drying or hot air drying. After completion of drying, the metal is removed and stored in a STP 8 through a device for removing metal such as a magnet.

By going through such a process, the dirt on the surface is removed, and a crushed resin with a certain size is obtained. This can be reused as it is or processed into pellets of a predetermined shape and reused. ing. (For example, see Patent Document 1)
JP 2001-337423 A (4th page, FIG. 4 etc.)

  According to the recycling method of the above-described waste resin molded product, the resin to be recycled has been cleaned by using a cleaning liquid to remove the dirt component on the resin surface. Therefore, in order to reuse the recycled crushing resin, it is necessary to remove the adhered dirt component without deteriorating the characteristics of the crushing resin with the cleaning liquid.

  In addition, in order to reliably remove the cleaning liquid from the surface of the crushed resin, a work process for performing sufficient rinsing and drying is necessary. Furthermore, it is necessary to maintain and manage the used cleaning liquid and the rinse cleaning liquid for detoxification such as neutralization.

The present invention has been made to solve the above problems, and an object thereof is to provide a dry-type recycling system can Ru can be removed contaminants resin surface in a manner that does not require a cleaning liquid.

In order to solve the problems as described above, the waste resin molded product recycling apparatus of the present invention crushes the resin molded product, and the surface of the resin crushed by impact caused by crushing and sliding contact between the crushed materials. A crusher for removing deposits in a dry manner, a crushing resin piece crushed into a predetermined shape and a contaminant containing the adhering matter to a wind power sorter while applying wind force, and the crushing resin piece, The air conditioner that separates the contaminants and separately stores the separated pieces of the crushed resin and the contaminants, and the crusher includes a plurality of fixed blades and a plurality of rotary blades. And a sieve plate provided so as to surround the rotary blade and having a plurality of holes of a predetermined size, the sieve plate being arranged concentrically with the rotary blade and having a predetermined shape of crushed resin pieces only the distance between the rotary blade so as to pass It has a configuration that can be an integer.

  With this configuration, the crusher passes through the sieve in a state where it is separated into crushed resin pieces and contaminants, and is directly transferred from the crusher to the wind power sorter by the transfer machine to which wind force is applied. Can be stored separately. For this reason, the reattachment of contaminants does not easily occur and reliable separation can be performed.

Further, the rotary blade is surrounded by a sieve plate that receives the cut crushed resin piece and contaminants, and allows only the crushed resin piece of a predetermined shape to pass through, and a space formed between the rotary blade and the rotary blade. Since it can be adjusted, the crushing resin piece having a shape that cannot pass through the sieve mesh is repeatedly crushed to a shape that can be passed by the rotary blade in the space surrounded by the sieve plate.

  By the impact at the time of crushing during this time and the sliding contact between the crushed materials, the contaminants consisting of dirt on the surface of the crushed resin, the altered layer, and the deposits can be reliably removed.

  Furthermore, the wind power sorter of the dry recycling processing apparatus for waste resin molded products of the present invention can adjust the strength and wind volume of the wind force, and is further provided with a plurality of separation adjusting plates for adjusting the wind force and the wind volume. The adjustment plates may alternately face each other and overlap each other with a predetermined interval so that the mounting angle, the gap between the inner wall of the apparatus and the interval between the separation adjustment plates can be adjusted.

In addition, the separation adjustment plate may have an attachment portion for attaching the separation adjustment plate to the inner wall of the wind power sorter, and may be provided with a plurality of holes in the vicinity of the attachment portion . Moreover, it is good also as a structure which further has an auxiliary | assistant board which can be moved and fixed and can adjust length.

  By setting it as such a structure, the optimal wind force, air volume, and the flow of a wind can be set according to the material of a waste resin molding product.

  Furthermore, the dry recycling apparatus for waste resin molded products of the present invention may be configured to use air set to a predetermined temperature and humidity as wind power. With this configuration, the inside of the device can be brought to a predetermined temperature and humidity atmosphere during the work process, and the generation of static electricity and moisture on the crushed resin pieces can be prevented, so that once removed contaminants are regenerated by static electricity and moisture. Adhesion can be prevented.

According to the dry recycling apparatus for waste resin molded products of the present invention, since no cleaning liquid is used, cleaning, rinsing and drying steps are not required. For this reason, a treatment apparatus such as cleaning waste liquid is unnecessary, and it can be made safer for the environment.

  In addition, the waste resin pieces produced by recycling do not cause deterioration due to the cleaning liquid, etc., and can substantially retain the resin characteristics originally possessed, and can stabilize the quality of molded products molded from this resin. There is a great effect that you can.

FIG. 1 is a flowchart for explaining a processing method using a dry recycling apparatus for waste resin molded products according to the present invention.

  In the STP 10, a resin molded product to be recycled among the electrical devices to be discarded including OA devices used at home is carried in.

  In STP11, various parts attached to the waste resin molded product are removed and sorted. In particular, metal parts are removed as much as possible because they tend to cause damage to the cutting blade in the crushing process. Along with the removal of these metal parts, the material of the resin molded product is selected and managed.

  Since materials that can be mixed and materials that should not be mixed are known in advance, only the materials that may be mixed are recycled at the same time. Thereby, the quality of the recycled product can be stabilized.

  Next, in STP12, the waste resin molded product is crushed by a crusher, and contaminants adhering to or adhering to the surface are removed. As the crusher, various methods such as a method of crushing between two rotating blades rotating so as to mesh with each other and a method of crushing between a drum-shaped rotating blade and a fixed blade can be used.

  However, since the crushing resin does not become a predetermined size by one crushing, it is necessary to have a structure in which crushing treatment is performed a plurality of times by a rotary blade. By performing such a crushing process a plurality of times, dirt on the surface of the crushing resin, deposits, and altered layers on the surface are removed from the surface by impact force during crushing, sliding between the crushing pieces, or scratching force, etc. .

  Next, in STP13, the crushing resin piece of a predetermined shape is sieved with a sieve plate. At this time, finely pulverized resin and contaminants also pass through the sieve plate. Hereinafter, these are collectively referred to as contaminants. Note that the crushing resin having a shape that does not pass through the sieve mesh is crushed by a crusher until the size of the resin passes through the sieve mesh.

  Then, in STP14, the crushed resin pieces and contaminants that have been sieved out are transported to the wind power sorter while applying wind power by the transporter. At this point, the crushed resin pieces and the contaminants that have passed through the sieve plate are in a separated state. It is preferable to carry out separation with a wind power sorter while maintaining the separated state in that the separation accuracy can be improved.

  If the state in which the crushed resin pieces and the contaminants are in contact with each other after the separation is maintained for a long time, the contaminants reattach and the sorting by simple wind sorting becomes difficult. For this reason, in order to hold | maintain the state with which the crushing resin piece and the contaminant are isolate | separated, it conveys, adding a wind force. When wind power is added in this way, the reattachment of contaminants is greatly suppressed, so that the separation accuracy in wind sorting can be greatly improved.

  Next, in STP15, a crushing resin piece and a contaminant are separated by wind sorting. At this time, since the crushed resin pieces and the contaminants are conveyed while applying wind force and are conveyed to the wind power sorter, the contaminants and the crushed resin pieces are kept separated from each other. As a result, it is possible to reliably select the wind force between the lightweight contaminants and the relatively heavy crushed resin pieces.

  Next, in the STP 16, among the crushed resin pieces and contaminants that have been separated, the contaminants flow in the same direction as the air flow and are stored in the contaminant storage container disposed at the air outlet. In addition, the crushed resin piece is collected in the crushed resin piece collection container after the metal piece is removed by a magnet installed in a nearby housing where the crushed resin piece collection container is arranged.

  In STP17, the collect | recovered crushing resin piece is sent to a recycling process, and is utilized again as a new resin molded product. At this time, the crushed resin piece can be used as it is in the next resin molding step, but may be used in the resin molding step after further pelletization. In addition, the collected contaminants and metal pieces are each disposed of after appropriate processing.

Since more than it is a processing method using a dry recycling apparatus of waste resin molding of the present invention, in the processing method using the dry recycling apparatus of the present invention, all the processing steps is a dry process, the washing liquid Since no chemicals or chemicals are used, there is no need for waste liquid treatment or the like, which not only simplifies the process but also reduces the environmental load.

  FIG. 2 is a schematic view showing an example of a specific processing apparatus for the above-described method for dry recycling processing of a waste resin molded product. 3 is a cross-sectional view of the crusher portion in this apparatus, and FIG. 4 is a cross-sectional view of the wind power sorter portion. In addition, the same code | symbol is attached | subjected to the same element.

  The dry recycling apparatus of the present invention includes a crusher 100, a conveyor 200 for conveying the crushing contaminants and crushing resin pieces from the crusher 100 to the wind power sorter 300 in a mixed state, and these contaminants. The air blower 650 for providing wind force for at least assisting the conveyance of the crushed resin piece, the wind sorter 300, the air suction device 400 for generating a predetermined air flow in the wind sorter 300, the crusher 100 and the wind force A temperature / humidity adjusting device 600 that adjusts the temperature and humidity of the introduced air in order to maintain the inside of the sorter 300 at a predetermined temperature and humidity, a contaminant storage container 500 that collects contaminants after separation, and a recyclable crushing resin piece It is comprised by the crushing resin piece collection | recovery container 550 which collect | recovers.

In order to blow the air from the temperature and humidity regulator 6 00 a wind sorter 300 and crusher 100, a crusher for air duct 800 crusher valve 850, and a sorter for air duct 700 sorter Valve 750 is provided. A sorter valve 750 and crusher valve 850, at the same time air from the temperature and humidity regulator 6 00 relative to the crusher 100 and wind sorter 300, or separately each to be blown selected arbitrarily Provided.

  FIG. 3 is a cross-sectional view for explaining the structure of the crusher 100 in more detail. The crusher 100 is provided with an openable / closable lid 104 on the upper side of a rectangular parallelepiped casing 102, and a waste resin molded product to be recycled is opened by opening and closing the lid 104. The crusher duct 800 is attached to the upper side of the casing 102, and the end of the transporter 200 is attached to the lower side.

  In addition, a drum-shaped rotary blade 110 is disposed at a substantially central portion of the housing 102. A plurality of rotary blades 110 are attached to the outer periphery of the drum 106 in such a manner that the cutting blades 108 can be replaced.

  The rotary blade 110 is rotationally driven by a motor having a load control function (not shown). A fixed blade 112 is disposed at a position facing the rotary blade 110. The size of the resin piece to be crushed is controlled by adjusting the gap dimension between the fixed blade 112 and the cutting blade 110. The fixed blade 112 also has a replaceable mounting structure.

  The sieve plate 114 is provided with a sieve having a predetermined size, and is concentric with the rotary blade 110 and arranged on the lower side of the rotary blade 110 with a predetermined interval. Contaminants removed from the surface of the waste resin molded product and crushed resin pieces having a shape passing through the sieve mesh pass through the sieve plate 114 and fall to the lower part, and these are caused by the conveying force including wind power. It is transferred from the transfer machine 200 to the wind power sorter 300.

  The transporter 200 is preferably configured to transport an object using wind power generated by the blower 650, but may be configured to transport not only wind power but also a combination of wind power and a belt conveyor, for example.

  Further, the transporter 200 may not have a structure in which the crusher 100 and the wind power sorter 300 are directly connected. For example, a configuration in which a mixture of crushed resin pieces and contaminants is once taken out from the crusher 100 and placed on a conveyor and conveyed to the wind power sorter 300 may be used. Alternatively, a configuration in which a cyclone is installed immediately before the wind power sorter 300 and the crushed resin pieces and contaminants are once stored and then thrown into the wind power sorter 300 may be used.

  FIG. 4 is a cross-sectional view for explaining the structure of the wind power sorter 300 in more detail. The wind power sorter 300 is provided with a plurality of separation adjustment plates 304 a, 304 b, 304 c, 304 d, and 403 e inside a cylindrical or rectangular parallelepiped casing 302, and the other end of the transporter 200 and the casing 302 The upper side part is connected.

  Further, a sorter blower duct 700 for feeding air adjusted in temperature and humidity is connected to the lower side surface of the casing. Furthermore, in order to generate a predetermined air flow, an air suction machine 400 is attached to the upper surface side, and a contaminant storage container 500 that collects the contaminants after separation is disposed in this extension.

  Further, a crushed resin piece collection container 550 for collecting crushed resin pieces is disposed on the lower surface side of the housing 302. A metal separation magnet 306 is disposed at a position immediately before the crushed resin piece falls into the crushed resin piece collection container 550, thereby preventing the metal piece from being mixed into the crushed resin collection container 550.

  The plurality of arranged separation adjusting plates 304a, 304b, 304c, 304d, and 304e are structured such that the angle change and the length can be adjusted independently within a certain angle range. In the dry recycling apparatus of the present embodiment, there are no particular restrictions on the number of separation adjustment plates 304a, 304b, 304c, 304d, and 403e, with four having a large shape and one having a small shape.

  The separation resin plates adjacent to each other, for example, the distance between the tip of the uppermost separation adjustment plate 304a and the flat portion of the next separation adjustment plate 304b are arranged such that the waste resin pieces fall but the contaminants are upward. It is adjusted to provide the optimal air flow rate and spacing that can be blown up.

  Similarly, the waste resin piece falls in the interval between the second sorting adjustment plate 304b and the housing 302 and the third sorting adjustment plate 304c, but the contaminants are blown upward. Is adjusted to provide the optimum air flow rate and spacing possible.

  Adjustments are similarly made on the other separation adjusting plates 304c and 304d. As described above, these adjustments are independently structured in such a way that the angle can be changed and the length can be adjusted within a certain angle range, so that the shape of the waste resin molded product and the shape of the waste resin piece can be adjusted independently. It can be done easily.

As a method for adjusting the angle and the length, for example, a separation adjusting plate 3040 as shown in FIG. The sorting adjustment plate 3040 shown in FIG. 5 has a configuration in which a first adjustment plate 3042 and a second adjustment plate 3046 which is an auxiliary plate slidable with respect to the first adjustment plate 3042 are attached.

Further, the first adjustment plate 3042 is provided with openings 3044 that are a plurality of holes in the vicinity of the attachment portion 3048 to the housing 302. This opening 3044 is for preventing air from staying in a region near the housing 302, and the pressure is reduced because air escapes through the opening, and the contaminant 30 can be prevented from staying in this region. .

  In addition to the separation adjustment plate 3040 having the configuration shown in FIG. 5, as a method for adjusting the angle and the length, a separation adjustment plate having various configurations may be used. For example, a wind separation plate is fixed to a mounting portion provided in the vicinity of the opening formed on the wall surface of the wind sorter, and is inserted into the wind sorting machine through the opening, and the length and angle can be set by this mounting portion. It is good also as a structure.

  Or, changing the angle or adjusting the length is only necessary when changing the material of the waste resin molded product or the shape of the crushed resin piece, so there is no need to adjust it when working under certain conditions. The optimum shape of the separation adjusting plate for various materials may be determined in advance, and when the material or the shape of the crushed resin piece is changed, it may be replaced with a corresponding separation adjusting plate.

  By using such separation adjusting plates 304a, 304b, 304c, 304d, and 304e, the crushed resin pieces 25 can be moved downward and the contaminants 30 can be moved upward to be efficiently separated.

  Next, the operation of this dry recycling apparatus will be described.

  The lid 104 provided on the upper part of the casing 102 of the crusher 100 is opened, and the waste resin molded product 20 to be recycled is put in. When the rotary blade 110 is rotated after closing the lid 104, the waste resin molded product 20 is cut by the rotary blade 110 and the fixed blade 112. Since the shape is not enough to pass through the sieve mesh in a single cut, the crushed pieces are rotated by the rotary blade 110, or are also cut in the space between the rotary blade 110 and the sieve plate 114, and The fractured pieces collide with each other and are repelled, and the surfaces of each other are rubbed.

  In this process, the contaminants consisting of the dirt, the altered layer and the deposits attached to the surface are removed and separated. When the crushing resin piece 25 having a size that passes through the sieve of the sieve plate 114 is repeated a plurality of times, the crushing resin piece 25 and the separated contaminants 30 are separated from each other. It passes through the mesh and falls to the lower part of the crusher 100.

  Since the size of the crushed resin piece 25 to be collected is often up to about 10 mm square, the mesh size of the sieve plate 114 is often set according to this size. In the case of the size of the sieve mesh, the contaminants 30 which are fine pieces or fine particles easily pass through the sieve plate 114.

  If the crushed resin pieces 25 and the contaminants 30 in the separated state are left as they are, the contaminants 30 adhere to the crushed resin pieces 25 again. When this adhesion occurs, it cannot be separated by a wind power sorter.

  For this reason, in the recycling processing apparatus of this Embodiment, it conveys to the wind power sorter 300 with the conveying machine 200, adding a wind force so that adhesion may not arise. Thereby, it is possible to reliably sort the crushed resin piece 25 and the contaminant 30 by the wind power sorter 300.

  By the way, a large crushed piece that cannot pass through the sieve mesh is repeatedly crushed in the space between the rotary blade 110 and the sieve plate 114 until it passes through the sieve mesh. If pieces or contaminants 30 accumulate too much, the motor that drives the rotary blade 110 will be overloaded.

  For this reason, the motor is allowed to perform load control, and when a load larger than a predetermined load is applied to the motor, the load control sensor detects and controls the introduction of the waste resin molded product 20 or outputs a signal for stopping the introduction. It is desirable that the motor be discharged without causing damage to the motor and enabling stable long-term operation.

  In addition, even if the crushing resin piece 25 and the contaminant 30 are separated by crushing and sieving by the crusher 100, if the inside of the housing 102 is dry, it tends to reattach to each other due to static electricity generated by sliding contact. . On the other hand, when the humidity in the housing 102 is high, the efficiency of separating the contaminants 30 from the surface of the shredded fragments due to impact is reduced, and the separated and removed contaminants 30 are also separated from the shredded resin pieces 25 by moisture. It becomes easy to adhere.

  On the other hand, in order to keep the temperature and humidity in the crusher 100, the conveyor 200, and the wind power sorter 300 constant, the temperature and humidity adjuster 600 adjusts the temperature to 40 ° C to 80 ° C and the humidity to 40% to 80%. The blown air is blown by the blower 650 through the crusher blower duct 800 and the sorter blower duct 700.

  Due to the wind force of the air whose temperature and humidity have been adjusted and the wind force of the carrier 200, the sieve effect of the sieve plate 114 is improved in the crusher 100 and the reattachment of the contaminant 30 and the crushing resin piece 25 is prevented. It becomes easy to do. However, depending on the installation location of the crusher 100 and the work environment, it may not be particularly necessary to adjust the temperature and humidity, and the temperature and humidity adjuster 600 may not be used.

The crushed resin pieces 25 and the contaminants 30 that have passed through the sieve plate 114 are transported to the wind power sorter 300 by the transporter 200. At this time, it can convey to the wind power sorter 300 in the isolate | separated state, without the contaminant 30 adhering to the crushing resin piece 25 by conveying while adding a wind force.
When the crushing resin piece 25 and the contaminant 30 conveyed to the wind power sorter 300 hit the uppermost separation adjusting plates 304a and 304e, the contaminant 30 is lightweight, and a part thereof is sucked by the air suction device 400. And stored in the contaminant storage container 500.

  The crushed resin piece 25 and the remaining contaminants 30 fall on the separation adjusting plates 304b, 304c, and 304d. In the process, the lightweight contaminants 30 gradually move upward due to the wind force from below. Then, separation from the crushed resin piece 25 is performed. As a result, the contaminant 30 is sucked by the air suction device 400 and stored in the contaminant storage container 500, and the crushed resin piece 25 falls and is stored in the crushed resin piece storage container 600.

  By the above operation, the waste resin molded product can be made into a waste resin piece 25 having a fixed shape and from which contaminants such as dirt on the surface, adhering matter and altered layer have been removed. The waste resin piece 25 may be used as it is to produce a new resin molded product, or a predetermined pellet may be produced from the waste resin piece 25 and a new resin molded product may be produced.

  The resin molded product produced in this manner did not show a difference in quality even when compared with a resin molded product produced by recycling by a conventional wet method. On the other hand, in the case of the dry recycle processing method and processing apparatus of the present invention, since no cleaning liquid, waste liquid, or waste water treatment is required, the burden on the environment is small, and the apparatus and operating costs are low.

  In the dry recycling apparatus of this embodiment, the crusher 100 is crushed by the drum-shaped rotary blade 110 and the fixed blade 112. However, the crusher 100 is crushed a plurality of times. However, the configuration of the crusher is not particularly limited as long as it can be rubbed against each other or scratched.

  Further, the sieve plate 114 is not necessarily limited to the configuration provided in a semicircular shape below the rotary blade, and the shape is not particularly limited as long as the crushed resin piece 25 having a predetermined shape can be sieved. Further, if the sieve plate 114 is configured by laminating plates having a plurality of sieve meshes, clogging of the sieve meshes is reduced, and it can be operated for a longer time.

  Further, in the dry recycling apparatus of the present invention, the wind power sorter 300 is configured to generate a predetermined wind force by the air suction device 400, but is not limited thereto. For example, it is good also as a structure which adds the air blower to the temperature / humidity adjustment machine 600 in addition to the air suction machine 400, and uses the wind force of this air blower.

  Further, in the dry recycling apparatus of the present invention, in order to maintain the temperature and humidity in the crusher 100 and the wind power sorter 300 at a predetermined value, air whose temperature and humidity have been adjusted in advance is introduced. In addition, a sensor for detecting temperature and humidity may be provided in the wind power sorter 300 to control the temperature and humidity of the air to be introduced.

  In the present embodiment, the shape of the waste resin piece 25 is about 10 mm square, but the shape of the waste resin piece 25 is a shape suitable for reuse, and the crushing process does not take too long. What is necessary is just to set and it is not specifically limited to about 10 mm square.

Unlike the wet recycling method using a cleaning liquid or water, the dry recycling apparatus for a resin molded product according to the present invention can remove contaminants adhering to the resin molded product by a dry process. In addition, there is no rinsing for cleaning liquid removal, and there is no drying process, so man-hours can be reduced and the increase in environmental burden due to waste liquid treatment can be prevented. As a recycling processing equipment for resin molded products such as home appliances and OA equipment Useful.
