Abstract

PROBLEM TO BE SOLVED: To provide an apparatus having a pouring port structure enabled to dust-collect granular substances by feeding the granular substances in a well-balanced manner onto an opposite rinsing deck, thereby to remove the dust particle and the foreign substances from the granular substances.SOLUTION: A dust collector 10 is provided with movable type pouring port deflection plates 40 for changing the flow rate of a granular substance to flow over a rinsing deck 20 by controlling the position by a biasing device 50. These pouring port deflection plates are formed with fixed type members extending between the front wall 17 and the rear wall of the dust collector and downward from an upper wall until these extensions are ended by spaced relations to the surface of the rinsing deck. A movable component interlocked to the biasing device so that it may lie on the fixed type member moves vertically as a whole with respect to the rinsing deck, and the flow of the granular substance to pass through the deflection plate stops if the movable member is arranged adjacent to the surface of the cleaning deck. The granular substance is reserved between the deflecting plates over the cleaning deck so that the granular substance is completely charged all over the width entirety of the cleaning deck when the deflection plate is deflected to a high position by a biasing device.

Description

  The present invention relates generally to an apparatus for cleaning and processing plastic pellets, particles, glass, and other particulate matter, and more specifically, an energizing force that blocks the flow of particulate material on the opposing wash deck. The present invention relates to a dedusting apparatus of a type in which an input deflection plate is controlled by an apparatus.

  In particular, it is important to remove impurities from the product particles as much as possible and maintain this state, as is known in the field of transporting and using particulates such as powders, granules and pellets. Normally, the granules can be mixed, packed or used in a pressurized tubular system that actually generates a flow of material that behaves somewhat like a fluid. It is to be transported by. As these materials move through the pipe, considerable friction occurs not only between the particles, but also between the tube wall and the flowing particles. When this friction occurs, there is then particle dust, broken particles, hair, streamers (ribbons that tend to “grow” and entangle for quite a long time), glass fibers of glass-filled products, etc. Occurs and obstructs material flow. The characteristics and characteristics of such a transport system are well known, and the importance and value of removing as much impurities as possible from the product particles and maintaining this state are also well known.

  As used herein, the term “contaminant (s)” encompasses a broad range of foreign materials, not only foreign materials but also broken particles or streamers of the product being transported. including. The generation of impurities, also called dust (dust containing microdust), is from many sources. For example, dust particles and shells generated during processing of plastic pellets that are reground because larger particles segregate. and hulls) and the like, and dust generated during the production of iron ore pellets, and as mentioned above, some pellets are transported by pipes and other transport / treatment systems. For example, when plastic is used, such extraneous impurities are harmful to the finished product. In particular, foreign materials having different compositions from primary materials such as dust and non-homogeneous materials of primary products such as streamers do not necessarily have the same melting point as that of the primary product, so that defects occur when a plastic material is melt-molded. Furthermore, streamers tend to impact the weighing scale and plug the metering screw during bag packaging.

  Considering product quality, and focusing on plastics that can be molded as a primary example, foreign substances that differ in composition from primary substances such as dust, and non-homogeneous substances in primary products such as hair and streamers. Since this primary product does not necessarily have the same melting point, defects occur when a plastic material is melt-molded. These defects are reflected in the finished product, causing discoloration, encapsulating foam, and sometimes being damaged or contaminated, making it impossible to bring to market. Because these non-homogeneous materials do not melt at the same temperature as the primary product, unmelted impurities can cause friction and premature wear of the molding machine, resulting in system shutdown, production discontinuation, and production. It is important to know that this leads to a reduction in performance and increases maintenance work, thus increasing the overall manufacturing cost.

  In most cases, dust and impurities are generated by the transport system, so not only do you have a device to completely clean the particles, but in order to avoid the generation of impurities by additional transport, you can use as much of the point of use of the particles It is basically important to have this nearby. Therefore, in order to purify substances in the field, compact dust removal devices have been used for many years that not only can deal with smaller volume products but also can completely purify the products. In the case of this compact dust removing device, it can be provided immediately before the final use point of the product. For example, just before packaging and bag packaging, just above the molding machine or extrusion machine, or at the top of the silo, or under the silo, after the initial stage where re-impurity may occur before product use. Can be provided. Of course, it is needless to say that the dust removing device can be equipped in the form of a self-supporting unit.

  The dust remover used to remove impurities from the particulates was issued on July 30, 1991 by Jerome I. U.S. Pat. No. 5,035,331 to Paulson. In this apparatus, air is blown upward onto the cleaning decks, and a flow of particulates containing impurities is passed through these decks, and impurities are removed from the particulates flow by the air flow flowing upward through the cleaning decks. Since the magnetic field is generated by the dust removing device, the flow of the particulate matter flows in the magnetic field, neutralizes the positive charge of the particulate matter, and promotes the removal of impurities from the particulate matter. The air flow including the impurities is discharged from the dust removing device, and the dust-removed particulate matter is put on the manufacturing process.

  On July 22, 2003, Jerome I. US Pat. No. 6,595,369 to Paulson also discloses a compact dust removal device. Similar to the large dust remover described in US Pat. No. 5,035,331, impurities having an electrostatic charge that attracts impurities to the neutralized particulates are removed from the particulate flow. This dust removal process is a process that uses an air flow that flows into a flow of particulates that flows over the cleaning deck. The air entrained with impurities is discharged from the top of the dust remover, while the particulate matter removed is discharged from the bottom of the dust remover.

  On June 3, 2008, Jerome I. US Pat. No. 7,380,670 granted to Paulson et al. And US Pat. No. 8,016,116 granted to Heinz Schneider on September 13, 2011 are equipped with a pair of opposing cleaning decks. Particulates containing impurities are received from a common supply port. A supply mechanism divides the particulate flow between two opposing wash decks, pours the fines into the air stream flowing through the first wash deck, and then into the laterally spaced venturi zones, with the second facing inward. Pour into the washing deck and feed the dust-free particulate matter to the central discharge opening. The air flow to the first and second wash decks is directed to a rear manifold with a central first opening and a laterally spaced lower opening below the second wash deck.

  These compact dust removers are provided with two consecutive wash decks, and in use they are fitted with a vertical conduit through which the particulates are transported to a production device that utilizes the particulates. That is, the product input opening at the top of the dust removing device is aligned in the vertical direction with the discharge opening of the dust-removed product. After the granular material is supplied to the charging opening and weighed, it is sent to the first cleaning deck in the diagonal direction, and air is blown into the deck from the air supply port to remove dust and foreign matters from the granular material flowing into the cleaning deck. In these dust removing apparatuses, the particulate matter is discharged from the lower end of the cleaning deck and falls through the venturi zone. In this venturi zone, the air rises and gives a harsh purification action to the particulate matter. Particulate matter falling through the venturi zone is received by a second wash deck in a direction opposite to the first wash deck and returns the particulate matter to a centered, dedusted product outlet.

  Further, when there is one input port and one discharge port, the operation of the conventional dust removing device is limited to supplying the dust-removed granular material flowing to the dust removing device to one receiving device. As already explained, the discharge from the dust removal device is loaded on, for example, a railway vehicle or truck or received in a collection bag. When the dust removing device is provided with one discharge port, the receiving device is only one that can be selected from these conventional devices.

  In the case of a dust remover with two discharge ports, this is used to load granular materials such as plastic pellets on a railroad car and transport them in bulk to a processing plant. It is necessary to equally distribute the particulate matter to be removed from the dust in the washing deck, and in this way, the discharge from the opposite discharge ports becomes substantially equal and can be loaded into the railway vehicle in a well-balanced manner. In the case of a circular slot, it is difficult to maintain an equal distribution of particulate matter to be dusted. This is because the granular material is not necessarily supplied to the inlet in a well-balanced manner. Furthermore, considering the configuration of the air supply port to the dust removing device, there are few structures where the dust removing device can be installed.

  As the capacity of the dust removal device increases, it is considered advantageous to supply the particulate matter to be removed on the counter cleaning deck of the dust removal device in a perfectly balanced state. Alternatively, in the case of staggered dust removal devices, it may be advantageous to generate a uniform flow over the entire width of the cleaning deck. In the conventional dust removing device, the flow of the particulate matter on the cleaning deck passes, for example, through a rotary valve and then flows into the rectangular cleaning deck via a circular inlet. As a result of this, it is usual that a uniform flow cannot be achieved across the width of the wash deck.

  It would be advantageous to be able to implement a dust removal device configuration that can evenly distribute particulate matter to be dust removed over the entire width of the cleaning deck. It would also be advantageous if the flow of particulates on the washing deck could be selectively terminated. Furthermore, it is considered to be advantageous to realize a dust removing device configuration that can omit the rotary valve from the entire combination of components and can supply the granular material to the circular supply opening.

  Dust removal devices are known. For a general description of the structure and operation of a conventional dust remover and a conventional small dust remover, see Jerome I. Reference should be made to USP 5,035,331 and USP 6,595,369 given to Paulson, the contents of each of these patent publications being incorporated herein. A typical granular material to be dedusted by the dust removing device 10 is a plastic pellet supplied to an injection molding machine to form a plastic molded product. Examples of plastic materials that remove impurities by the dust removing device 10 are polyester, acrylic, high density polyethylene, polypropylene, nylon, polycarbonates, styrene, low density polyethylene, and the like. Any type of granular anhydrous bulk material such as minerals, foodstuffs, drugs, etc. can be removed by the dust removing device 10.

  1 to 4, a dust removing device 10 to which the principle of the present invention is applied includes a material inlet 13 at the center. For example, when this inlet is connected to a vertical portion of a fluid material processing system (not shown), the granular material is fed into the granular inlet 13 provided at the center in the transverse direction at the top of the main housing 11 which is entirely airtight. Can do. As will be described in detail below, the main housing 11 supports a pair of opposed cleaning decks 20 that receive particulate matter to be removed from the inlet 13. The main housing 11 has an air supply path 15, and the supply path has an air supply port 16 provided in the rear wall 12 of the main housing 11. As will be described in detail below, when an air flow is introduced from the air supply port 16, the air flows to the cleaning deck 20, and dust is removed from the particulate matter.

  Material particles flow from the granular material inlet 13 to the cleaning deck 20 where dust removal can be performed. Since the magnetic coil 13a that generates the magnetic flux field is attached to the inlet 13, the particulate matter to be removed flowing into the main housing 11 is affected by the magnetic field, neutralizing the electrostatic charge of the granular pellet, In particular, microdust is easily separated from the pellets. As will be described in detail below, air is supplied to the main housing 11 from a clean air inlet port 16 (clean air inlet port) provided in the rear wall 12, and the clean air flows into the main housing 11. A portion of the clean air that flows from the inlet opening 16 flows up through the wash deck 20 and the remaining portion of the clean air that flows into the main housing 11 is distributed to the venturi zone 30. This will be described in detail below.

  Since the washing deck 20 is supported by the main housing 11 between the front wall 17 and the rear wall 12, a descending slope extends from the granular material inlet 13 in the opposite direction to the discharge end of the washing decks 20. . On this descending slope, particles in the form of particles to be removed move by gravity. Particulates fall through the venturi zone 30 to the second wash deck 22 where they are subjected to the additional wash air flow and then sent to the product outlet 14.

  A pair of inlet deflectors 40 are attached to the main housing 11 in a manner described in detail below. The flow of the particulate matter on the surface of the upper cleaning deck 20 is controlled by the deflection plate 40. The larger the gap between the inlet deflection plate 40 and the cleaning deck, the larger the flow rate. The inlet deflection plate 40 has a trailing leg 46 (trailing leg) whose orientation is parallel to the inclination of the washing deck 20 as a whole. The laminar flow flows down along the surface of the cleaning deck 20, passes through the deflecting plate 40, and then goes to the venturi zone 30.

  The cleaning deck 20 is formed as an inclined tray having a generally horizontal slot 25 and an upper surface 24 with a circular opening. These formed horizontal slots 25 correspond to upwardly extending deflecting plates that become ramps with respect to the particulates flowing down along the upper surface 24 of the cleaning deck 20. The slot 25 is formed as a horizontal opening across the upper surface 24 between the deflecting plate and the upper surface 24, so that the air flowing in the slot 25 is directed toward the granular material in the horizontal direction as a whole by the deflecting plate. Change. The deflection plate is slightly upward with respect to the inclination of the upper surface 24 of the cleaning deck 20. The air flowing through the circular opening is generally orthogonal to the inclined upper surface 24 of the cleaning deck 20.

  As a result of the flow of particulates in this manner, the particulates are subject to downward acceleration along the surface of the cleaning deck, as well as the movement of the particulates on the deflector plate and the substantial exiting from the circular openings and horizontal slots 25. Under the influence of turbulent flow that generates a vertical air flow. For this reason, impurities such as dust and foreign matters are taken out from the particulate matter and carried to the polluted air outlet 19 at the top of the housing 11 by the air flow.

  The particulate matter falling from the lower discharge end portion 21 of each cleaning deck 20 falls vertically as a whole toward the corresponding second cleaning deck 22 through the venturi zone 30. In this venturi zone 30, air is blown upward onto the falling particulate matter, and intense final cleaning is performed. This air is blown into the venturi zone 30 from below the washing deck 20 through a louver 29 and through the air flowing to the second washing deck 22. Clean air can also be supplied to the venturi zone 30 via the bypass duct 35. The main housing 11 is provided with a clean air plenum or clean air manifold 18 behind the rear wall 12, which is in fluid communication with the clean air supply port 16 to direct the air flow to the wash decks 20, 22 and Supply to the bypass duct 35.

  The bypass duct 35 that supplies air flow forward around the main housing 11 and returns to the main housing 11 in front of the rear wall 12 is located behind the pivoting member 36 corresponding to the venturi zone 30. Provide below. The amount of air flowing through the bypass duct 35 is controlled by a pivoting damper 36 that is pivotably mounted within the bypass duct 35. The size of the venturi zone 30 and the amount of air toward the venturi zone 30 are controlled by a pivot type member 36 that is interlocked with a position adjusting lever 37 that protrudes outside the main housing 11.

  The flow of air from below the pivoting member 36 and through the louver 29 toward the venturi zone 30 provides a substantial cleaning action for the particulates falling through the venturi zone 30 but contaminates the particulates. Not so violent as to soar to the air outlet 19. If too much air flows into the venturi zone 30, the pivot damper 36 moves backward to increase the effective size of the venturi zone 30 and suppress the amount of air flowing into the venturi zone 30. As can be seen from the accompanying drawings, when the front wall 17 of the main housing 11 is made of transparent or translucent polycarbonate, the operation state of the cleaning deck 20 is physically observed by seeing through the front wall 17. It is possible to confirm whether the particulate matter is carried to the polluted air outlet 19.

  The air flow including dust and foreign matters is discharged from the main housing 11 through the polluted air discharge ports 19 located at the upper part higher than the venturi zone 30 and on both sides of the granular material input port 13. The transparent front wall 17 of the main housing 11 can be configured as a hinged door, and the handle 17a is attached thereto, so that the front door 17 can be easily operated when it is removed from the frame 11a. Alternatively, in the case of the front wall 17, instead of a hinge configuration, the front wall 17 may be configured to be removable by releasing an appropriate fixture that connects the front wall 17 to the housing frame 11 a. Alternatively, the frame 42 of the front wall 17 can be configured to be detached from the main housing 11 by removing the fixture 17b from the frame support 43 that connects the main housing 11. When the front wall 17 is removed, internal components such as the cleaning deck 20, the deflecting plate 40 and the pivot member 36 can be removed from the main housing 11, and the inside of the main housing 11 and the removed components can be easily cleaned. become.

  As can be understood from the best mode shown in FIG. 5 to FIG. 7, a fixed member 42 fixed to the upper portion of the main housing 11 is formed on the charging port deflection plate 40. Since this fixed member 42 extends between the front wall 17 and the central wall 17, the particulate matter is between the fixed member 42 and the wall of the main housing 11. There is no flow. A movable member 45 is attached to the fixed member 42. The movable member 45 also extends at the same height between the front wall 17 and the central wall 17 but is connected to an actuator 50 that affects the flow of the surface of the fixed member 42. As shown in the figure, the movable member 45 can be positioned between the highest movement position and a low height position, and since the low height position is close to the upper surface of the cleaning deck 20, the granular material is charged into the inlet. It does not pass through the deflection plate 40. At this low position, the charging port deflecting plate 40 effectively seals the cleaning deck 20, so that the granular material is stored, and the upper part of the cleaning deck 20, the deflecting plate and the granular material charging port 13 facing in the lateral direction. The volume of the main housing 11 that is in contact with is filled.

  When the particulate matter is stored in this way, the particulate matter is completely loaded on the cleaning deck between the front wall 17 and the rear wall 12, so that the inlet deflection plate 40 is raised to allow the particulate matter to flow. Furthermore, the flow of the entire width of the cleaning deck 20 is made uniform. When the granular material continuously flows through the granular material input port 13, the washing deck 20 is completely loaded, so that the effect of the dust removing device 10 is enhanced. Each charging port deflection plate 40 has a rear leg 46 formed as a part of the movable member 45, and its direction is parallel to the upper surface of the cleaning deck 20. Forced laminar flow (into a laminar flow). The linear tab 48 is fixed to the movable member 45, protrudes downward from the rear leg 46, and acts as a member that restricts the flow. When the inlet deflection plate 40 is in a low position, the linear tab 48 is in close contact with the surface of the cleaning deck 20, and the rear leg 46 is positioned higher than the cleaning deck 20.

  In the urging device 50, the power source may be hydraulic, pneumatic, or electric, and the rod 51 extending therefrom is extended and connected to the movable member 45. The biasing device rod 51 and the movable member 45 are linearly along the fixed member so as to approach the cleaning deck 20 linearly along the fixed member 42 and away from the cleaning deck 20 (linearly along the fixed member). 42 toward and away from the wash decks 20) Configure. The urging device rod 51 can be removed from the movable member 45, and the urging device 50 can also be detached from the main housing 11 and the dust removing device 10, so that maintenance and repair are easy.

  When the dust remover 10 is operated, the product discharge port 14 is installed at an appropriate position where it can be used according to the purpose, and connected to a granular material supply source via the granular material input port 13. The granular material is charged from the granular material inlet 13 and is held in front of the inlet deflection plate 40 by the linear tab 48 at a low height, so that the granular material is stored on the washing deck 20 and The main housing volume is filled between the inlet deflection plates 40. When the charging port deflection plate 40 is set to a required height after filling, the granular material having the target flow rate passes through the charging port deflection plate 40 and falls to the cleaning deck 20. After passing through the linear tab 48, the particulates are forced to laminarize by the rear legs 46 and flow onto the inclined wash deck 20 in the opposite direction.

  Clean air is received from the clean air supply port 16, travels to the main housing 11 below the wash deck 20, flows to the louver 29 and the second wash deck 22, and enters the venturi zone 30. Air flowing into the main housing 11 below the cleaning deck 20 flows into slots 25 and openings formed in the cleaning deck 20. The air passing through the slots 25 and openings of the cleaning deck 20 generates turbulence in the granular material moving along the upper surface of each cleaning deck 20. This turbulent flow is strengthened by the orientation of the deflection plate projecting upward from the upper surface 24 and the direction of the horizontal slot 25 that accelerates the particulate matter flowing to the cleaning deck 20 and further strengthens the turbulent flow. Due to this movement of the air flowing through the washing deck 20 and passing through the flowing particulate matter, dust and foreign matter are removed from the particulate matter, and a static suction force is induced to the particulate matter inlet 13 by the magnetic flux generator 13a. Neutralized by the magnetic field generated.

  8 to 14 will be described. These drawings are diagrams showing the best mode of another configuration of the dust removing apparatus 110 to which the principle of the present invention is applied. The dust removing device 110 has a granular material inlet 113 at the center, and the inlet 113 is connected to, for example, a vertical portion of a fluid processing system (not shown). It can be charged into a granular material inlet 113 provided at the center. As will be described in detail below, the main housing 111 supports a pair of cleaning decks 120 facing in opposite directions, and these decks 120 receive particulate matter to be removed from the inlet 113. The main housing 111 constitutes an air supply path 115 having an air supply port 116 on the rear wall 112 of the main housing 111. As will be described in detail below, when an air flow is introduced from the air supply port 116, the air is directed to the cleaning deck and dust is removed from the particulate matter.

  Material particles flow from the granular material inlet 113 to the cleaning deck 120 where dust removal can be performed. Since the magnetic coil 113a that generates the magnetic flux field is attached to the inlet 113, the particulate matter to be removed flowing into the main housing 111 is affected by the magnetic flux field, and the electrostatic charge of the granular pellet is neutralized. In particular, microdust is easily separated from the pellets. As will be described in detail below, air flows into the main housing 111 from the clean air supply port 116 provided on the rear wall 112, and the clean air flows into the main housing 111. A portion of the clean air flowing from the supply port 116 flows upward through the cleaning deck 120, and the remaining portion of the clean air flowing into the main housing 111 is directed to the venturi zone 130. This will be described in detail below. A person skilled in the art should understand that a baffle (not shown) needs to be provided in order to divide the clean air flow between the cleaning deck 20 and the venturi zone 130 according to the purpose. .

  Since the cleaning deck 120 is supported by the main housing 111, a descending slope is formed extending in the opposite direction from the granular material inlet 113 to the product outlet 114 spaced in the transverse direction. On this descending slope, for example, particulates such as particles move by gravity. The charging port deflector 122 is attached to the main housing 111 so as to slide along the upper surface of the main housing 111 and direct the particulate matter toward the cleaning deck 120. The inlet deflection plate 122 has a rear leg 123, and this rear leg is generally parallel to the inclination of the cleaning deck 120, so that the particulate matter is forcibly laminarized. The flow flows down along the surface of the cleaning deck 120 toward the product outlet 114. The sliding of the inlet deflection plate 22 can be realized by biasing a linear biasing device 155 (The sliding movement of the inlet deflector 22 can be effected by operation of a linear actuator 155). The direction of the biasing device 155 is set so as to move in parallel with the upper portion of the main housing 111, so that the laminar flow depth is obtained by moving the position of the inlet deflection plate 122 to the target position. Can be adjusted.

  The cleaning deck 120 is formed as an inclined tray having a generally horizontal slot 125 and an upper surface 124 having a circular opening. These formed horizontal slots 125 correspond to deflecting plates that extend upward and become inclined portions with respect to the granular material descending the upper surface 124 of the cleaning deck 120. Since the slot 125 is formed as a horizontal opening across the upper surface 124 between the deflecting plate and the upper surface 124, the air flowing in the slot 125 is directed toward the granular material in the horizontal direction as a whole by the deflecting plate. Change. The deflecting plate is slightly upward with respect to the inclination of the upper surface 124 of the cleaning deck 120. The air flowing through the circular opening is generally orthogonal to the inclined upper surface 124 of the cleaning deck 120. As a result of the flow of particulates in this manner, the particulates are subject to a downward acceleration along the surface of the cleaning deck, as well as the movement of the particulates on the deflection plate and the substantial exit from the circular openings and horizontal slots 125. Under the influence of turbulent flow that generates a vertical air flow. For this reason, impurities such as dust and foreign matters are taken out from the particulate matter and carried to the polluted air discharge port 119 at the top of the housing 111 by the air flow.

  The granular material falling from the lower discharge end portion 121 of each cleaning deck 120 falls vertically as a whole with respect to the corresponding dust-removed product discharge port 114 and enters the venturi zone 130. In this venturi zone 130, air is blown upward onto the falling particulate matter, and intense final cleaning is performed. As can be understood from the best mode of FIG. 13, this air is blown into the venturi zone 130 from below the cleaning deck 120 via the louver 129 of the support leg 128. Clean air can also be supplied to the venturi zone 130 via the bypass duct 145. As can be seen from the best mode of FIG. 14, the main housing 111 is formed with a transverse vertical central wall 117 to which the washing deck 120 is attached. A clean air plenum between the rear wall 112 and the central wall 17, i.e., a clean air manifold 118, is in fluid communication with the clean air supply 116 a of the central wall 117 and directs the air flow to the wash deck 120.

  Clean air plenum 118 is also in fluid communication with bypass duct 145. A bypass duct 145 that supplies air flow forward around the main housing 111 and back to the main housing 111 in front of the central wall 117 is located behind the pivoting member 135 corresponding to the venturi zone 130. Provide below. The amount of air flowing through the bypass duct 145 is controlled by a damper 146 that is pivotably mounted within the bypass duct 145. The size of the venturi zone 130 and the amount of air flowing toward the venturi zone 130 are controlled by a pivoting member 135 that is linked to a position adjusting lever 136 that protrudes outside the main housing 111.

  The flow of air entering the venturi zone 130 from below the pivot member 135 and through the louver 129 provides a substantial cleaning action for the particulates falling through the venturi zone 130, but the particulates Not so violent as to soar to the polluted air outlet 19. If too much air flows into the venturi zone 130, the pivot member 135 is retracted, increasing the effective size of the venturi zone 130 and reducing the amount of air flowing into the venturi zone 130. As can be seen from the accompanying drawings, when the front wall 140 of the main housing 111 is made of transparent or translucent polycarbonate, the operation state of the cleaning deck 20 is physically observed by seeing through the front wall 140. It is possible to confirm whether the particulate matter is carried to the polluted air outlet 119.

  The support member 128 extending downward from the discharge edge 121 of the cleaning deck 120 is engaged with the main housing 111 at an angle inward from the discharge edge 121 of the cleaning deck, as shown in FIG. Configure to be able to match. With this angular configuration of the support member 128, air flows outward from the louver 129 and enters the venturi zone 130 from which particulate matter falls from the discharge edge 121 of the cleaning deck 120. That is, since the direction of the air flow from the louver 129 has an angle with respect to the vertical movement of the granular material falling from the cleaning deck 120, the dust removal in the venturi zone 130 where the horizontal dimension is considered to be the narrowest at the discharge edge 121. The action becomes stronger.

  The air flow including dust and foreign matter is discharged from the main housing 111 through the dirty air discharge ports 119 located at the upper position higher than the venturi zone 130 and on both sides of the granular material input port 113. A sliding plate 133 is provided in the polluted air discharge path 119a, and the position can be adjusted by slidingly inserting each plate 133 into or out of the polluted air discharge path 119a. This forms a throat opening in the polluted air discharge path 119a.

  In the case of the transparent front wall 140 of the main housing 111, it can be removed from the main housing 111 by releasing the fixture 141 from the frame support 143 that connects the frame 142 of the front wall 140 to the main housing 111. Alternatively, the front wall 140 can be formed as a hinged door with a handle 144, which facilitates its operation when it is removed from the frame 142. When the front wall 140 is removed, internal components such as the cleaning deck 120, the inlet deflection plate 122, and the pivoting member 135 can be removed from the main housing 111, and the inside of the main housing 111 and the removed component 120, 122 and 135 can be easily cleaned.

  The inclination of the cleaning deck 120 is calculated and set so as to optimize the flow of particulates passing through the upper surface 124 of the cleaning deck 120 and the air cleaning. Since the two product outlets 114 spaced apart in the transverse direction are aligned with the corresponding cleaning deck 120, the dedusted particulate matter can be packaged in two different ways. For example, different packaging bags (not shown) may correspond to each of the product outlets 114, or these packaging bags may be used to supply two different production lines. In use, the product outlet 114 provided in the opposite direction is substantially flexible.

  When the dust remover 110 is operated, the product discharge port 114 is installed at an appropriate position that can be used according to the purpose, and is connected to a granular material supply source via the granular material input port 113. The granular material is input from the granular material input port 113, becomes a laminar flow by the input port deflecting plate 122, and flows to the inclined cleaning deck 120 in the opposite direction. The positions of these input port deflection plates can be adjusted with respect to the cleaning deck 120, and the thickness of the granular material flowing through the cleaning deck 120 can be set according to the purpose.

  The clean air is sent from the clean air supply port 16a, flows into the main housing 111 below the cleaning deck 120, and flows into the venturi zone 130 through the louvers 129 of the support legs 128 of the cleaning deck 120. Air flowing into the main housing 111 below the cleaning deck 120 flows into slots 125 and openings formed in the cleaning deck. The air passing through the slots 125 and openings of the cleaning deck 120 generates turbulence in the granular material moving along the upper surface of each cleaning deck 120. This turbulent flow is strengthened by the direction of the horizontal slot 125 that accelerates the deflecting plate protruding upward and the granular material flowing to the cleaning deck 120 and further strengthens the turbulent flow. This movement of the air flowing through the washing deck 120 and passing through the flowing particulate matter removes dust and foreign matters from the particulate matter, and a static suction force is guided to the particulate matter inlet 113 by the magnetic flux generator 113a. Neutralized by the magnetic field generated.

  The dust-removed product granular material is discharged from the lower end 121 of the cleaning deck 120 and falls into the corresponding venturi zone 130. In the venturi zone 130, an upwardly moving air flow from the louver 129 and the bypass duct 145 of the cleaning deck support leg 128 flows. This air flow flows behind the venturi deflector plate member 135, then flows under it, and flows into the venturi zone 130. This upwardly moving air flow gives severe dust removal to the particulates falling from the venturi zone 130, and the air flow from this flows through the cleaning deck 120 to the dirty air discharge port 119 at the top of the main housing 111. To join. Dust-removed product granules fall from each product outlet 114 and are packaged or transported to a manufacturing plant. Since the front wall 140 of the main housing 111 is transparent, the operating state of the dust removing device 110 can be visually checked, and the input port deflection plate 122 or the venturi deflection plate member 135 is operated by operating the control lever 136 that moves the pivot type venturi deflection plate member 135. You can check if it is necessary to adjust. Further, the removable front wall 140 facilitates access to the interior of the main housing 111 and facilitates cleaning of the main housing 111 and all removable components therein.

  15 to 20 show the best mode of still another embodiment of the dust removing apparatus with improved operating efficiency. In the case of the dust removing device 110 having a pair of opposed cleaning decks 120, the operation is more effectively performed when the granular material flow input from the granular material input port 113 is substantially equally divided between the two cleaning decks 120. The flow of the particulate matter in a balanced manner to the two washing decks 120 has no relation to whether the two product discharge ports 114 are formed alternately in the main housing 111 or one product discharge port 114 is formed. By providing adjustable inlet deflectors 122 and centering the apex between the two opposing cleaning decks 120 in the inlet 113, the particulate flow distribution can be balanced, When the input opening 113 is used, the fluctuations in the particulate flow through this opening are due to the wash deck 120 unless a biasing device controlled input deflector is used to form a fully filled rectangular configuration. This means that it becomes more difficult to continuously balance the flow flowing over the entire top surface of the plate.

  In order to improve the balance of the granular material flowing to the cleaning deck 120, a rectangular inlet structure 150 constitutes an inlet box 151, which extends to the upper part of the cleaning deck 120, and deflects the inlet. Limited by plate 122 and rectangular inlet structure 150. The depth of the inlet box 151 is substantially equal to the width of the cleaning deck 120, and therefore, an inlet box is formed between the front wall 140 and the rear wall 112 of the main housing 111 and the inlet deflection plate 122. The inlet box 151 is connected to the rectangular inlet 152 vertically from the upper portion of the cleaning deck 120 and to the rectangular inlet 152 via a rectangular flange 154, and from a supply source such as a silo (not shown). It extends into an intermediate member 153 that terminates in a circular flange 113 that can be connected to a normal conduit that transports particulate matter to the dust remover 110. The inlet 152 in this embodiment is rectangular, but the particulates flow in a well-balanced manner over the entire width of the cleaning deck 120. This is because the apex set at the center of the cleaning deck 120 ensures a uniform distribution between the opposing cleaning decks 120, and because the biasing device control type inlet deflection plate 122 is used, cleaning is performed. This is because a completely loaded distribution can be secured over the entire width of the deck 120.

  When the main housing 111 is streamlined by transferring the clean air supply port 116 from the rear wall 112 of the main housing 111 to the center of the floor 48 of the main housing 111, the clean air plenum 118 can be omitted. Generally, since the clean air source can be connected to the dust removing device 110 by a horizontal conduit (not shown), it is considered that the dust removing device 110 needs a 90 ° intermediate member 157 connected to the clean air supply port 116. Accordingly, clean air is sent to the main housing 111 through the floor 148 under the wash deck 120. As already described in detail, the clean air is forced to be blown into the slot 125, so that dust and foreign matter can be removed from the flow of particulate matter flowing on the upper surface 124 of the cleaning deck 120. As already described, since the clean air is also directed to the louver 129 in the support 128 of the cleaning deck 120, the venturi zone 130 is formed between the discharge end of the cleaning deck 120 and the corresponding side wall of the main housing 111. To do.

  A capture air conduit 158 is formed in the main housing 111 to supplement the flow of clean air to the venturi zone 130. These supplemental air conduits 158 are in fluid communication with the interior of the main housing 111 through supplemental air supply openings 159 in the rear wall 112. The supplemental air conduit 158 wraps around the main housing 111 and terminates in the venturi zone 130 so that trapped air can be sent from the air coming through the louver 129 to the opposite venturi zone 130. As previously described, the venturi zone 130 is provided with a pivoting member 135 and a position adjustment lever 136 to selectively control the flow of supplemental air from the conduit 158 to the venturi zone 130.

  A person skilled in the art should understand that the flow of the granular material flowing in the washing decks 20 and 120 can be adjusted depending on where the input deflecting plates 40 and 122 are provided. The operation of the inlet deflection plates 40 and 122 is preferably controlled by operating the biasing devices 55 and 155 connected to the inlet deflection plates 40 and 122. The power source of these biasing devices 55, 155 may be electric, compressed air, or pressurized hydraulic fluid, and can be remotely controlled by operating an integrated electronic circuit system 156 that can be located at a remote location. In this manner, the deflection plate mechanisms 40 and 122 can be remotely controlled through the operation of the integrated batch electronic control system 156. Further, the input port deflecting plates 40 and 122 can be operated independently. Therefore, when this is used, the dust removing device 10 is blocked by blocking the flow of the granular material to the selected cleaning deck among the cleaning decks 20 and 120. , 110 can be selectively stopped, or the flow of particulates on the two wash decks 20, 120 can be stopped simultaneously. Since the inlet deflection plates 40 and 122 can be controlled, other control valves such as a rotary valve or a stop valve are not necessary on the dust removing devices 10 and 110.

  In operation, the inlet deflection plates 40 and 122 are deflected and engaged with the upper portions of the respective cleaning decks 20 and 120 through the operation of the adjustment biasing devices 55 and 155, so that the cleaning decks 20 and 120 are connected to each other. The flow of particulate matter is blocked from the input port box 151. Since the granular material is continuously supplied from the inlets 13 and 113, the granular material is stored until the granular material is filled in the inlet box 151 and the accumulated granular material vertically enters the rectangular inlet 52. . Next, the urging devices 55 and 155 are urged again to deflect the charging port deflecting plates 40 and 122 so that the end of the charging port deflecting plate and the adjacent cleaning decks 20 and 120 are separated. The flow of the material passes through the inlet deflection plates 40 and 122 and falls onto the upper surfaces 24 and 124 of the cleaning decks 20 and 120, and the dust removal process is performed as already described in detail.

  The deflection operation of the inlet deflection plate 40 is generally perpendicular to the upper surface 24 of the cleaning decks 20, 120, while the deflection operation of the inlet deflection plate 122 is parallel to the upper surface of the main housing 111. The deflection operation of the charging port deflection plate 40 perpendicular to the cleaning decks 20 and 120 is preferable to the deflection operation of the charging port deflection plate 122. This is because the charging box 151 becomes a significant obstacle when deflecting the charging port deflecting plate 122 toward the cleaning deck 120 along a path parallel to the upper surface of the main housing 111 when filling the granular material. Before filling the inlet box 151, the inlet deflector 122 is positioned against the wash decks 120 so that the inlet deflector 122 is separated from the washing deck 120. The movement of the inlet deflectors 122 away from the wash decks 120 causes the particulates to begin to flow easily over the top surface 124 of the wash deck 120. When the flow of the particulate matter is sufficient, the biasing device 155 deflects the inlet deflection plate 122 inward with respect to the cleaning deck 120, but the deflection is not as effective as the deflection of the inlet deflection plate 40. In the case of the deflection operation of the inlet deflection plate 40 perpendicular to the cleaning deck 20, it acts as a knife for opening and closing the flow of the granular material flowing to the cleaning deck 20, and the uniform flow of the granular material flowing on the upper surfaces of the cleaning decks 20 and 120. It is not necessary to forcibly change the size of the inlet box 151 held as

  One skilled in the art will appreciate that for a rectangular slot 151, it is not necessary to utilize the rectangular slot 152 and corresponding intermediate member 153 and corresponding flange 154. This is especially true when the input port deflection plate 40 that deflects vertically with respect to the cleaning deck 20 is used. When the input port box 151 is formed upward with respect to the circular input port 13 at a position higher than the cleaning deck 20 between the input deflecting plates 40, the input port box 151 becomes rectangular, so that it is loaded into the cleaning deck 20. And the distribution of the particulate flow is uniform over the entire width of the washing deck 20.

  As long as the inlet box 151 is filled with particulate matter, and as long as the distance between the end of the inlet deflection plates 40, 122 and the corresponding upper portions 24, 124 of the wash decks 20, 120 is equal, the inlet deflection The flow of the particulate matter passing through the plates 40 and 122 and falling on the upper surfaces 24 and 124 of the cleaning decks 20 and 120 is maintained in a well-balanced state, and as a result, discharged from the lower discharge ends of the cleaning decks 20 and 120. The flow of the dust-removed particulate matter will remain substantially equal. In the case of the configuration of the dust removing device 110 in which the two discharge ports 114 are alternately provided, the flows discharged from the discharge ports 114 are substantially equal.

  The dust removing apparatuses 10 and 110 shown in FIGS. 1 to 20 can be used particularly when the dust-removed granular material is loaded on the railcar 160 or other bulk carrier. As shown in FIG. 20 for the dust remover 110, the main housing 111 is supported by the I-beam 5. Two of these I-beams can be fastened to the mounting bracket 149 with bolts, and are close to the silo 161 having a predetermined amount of granular material to be removed by the railway vehicle loading station or the dust removing device 110. Then, the dust removing device 110 can be fixed to the I-beam support 5 and then loaded onto the railway vehicle 160. In such an environment, it is extremely important to set the cleaning deck 120 in a well-balanced manner and evenly distribute the dust-removed particulate matter to the railcar 160 or truck (not shown). When loading on one side of the railway vehicle 160 is faster than on the other side, the loading of each part of the railway vehicle 160 becomes incomplete, and the efficiency of bulk loading becomes poor.

  FIG. 20 shows a bulk loading method to the railway vehicle 160. Particulate matter is continuously charged from the silo 161 into the inlet 113 of the dust removing device 110. As already described, since the balance of the flow of the particulate matter is uniform between the cleaning decks 120, the particulate matter removed from the outlet 114 can be evenly discharged. For example, the dedusted particulate matter is first sent to the outer supply line 162 and partially loaded into the outer compartment to balance the loading of the rail vehicle 160. The exhaust sleeve 166 exhausts from this compartment while the particulates are filling the railway vehicle compartment. Next, the shut-off valve 165 of the inner line 164 is opened to supply to four compartments.

  When one compartment is filled, the corresponding shut-off valve 165 closes and directs all remaining flow to the adjacent compartment, until both compartments are filled. If one end of the railway vehicle 160 is not completely filled, the railway vehicle 160 is completely filled by closing the biasing device 155 corresponding to the inlet deflection plate 122 on the above side of the railway vehicle 160 with respect to the washing deck 120. Until then, the granular material is allowed to flow on the unfilled side of the railway vehicle 160. That is, it is preferable for those skilled in the art to allow a uniform flow of particulates to flow through the opposing outlets 114 so that one end of the railway vehicle is not filled before its opposite end is filled. You should be able to understand that.

  If the loading of one end of the railway vehicle 160 (or other bulk carrier) is not complete, the inlet deflection plate 122 of the opposing cleaning deck 120 is deflected and engaged with the opposing cleaning deck 120. Since the flow of the granular material flowing to the opposite washing deck 120 stops, the granular material flows on the upper surface only in the washing deck 120 corresponding to the end portion where the railcar 160 is not loaded, and the end where the railcar 160 is not loaded. Loaded into the department. When loading on both railcars 160 is completed, both the inlet deflection plates 122 are closed with respect to the corresponding washing decks 120, so that the inlet box 151 is filled with granular materials and the next railcar 160 is loaded. I come to.

  In the case of a preferred embodiment shown in the accompanying drawings, a pair of biasing device control type inlet deflection plates interlocking with a corresponding opposite cleaning deck are used, but corresponding to one cleaning deck 20, 120. In the case of the configuration of the single inlet deflection plates 40 and 122 formed as described above, the flow of the granular material flowing on the upper surfaces of the single cleaning decks 20 and 120 can be controlled. The one washing deck 20, 120 discharges the particulate matter to one second washing deck 22, and the particulate matter that has been dust-removed next is perpendicular to the inlet 13, as shown in FIG. Direct to the aligned outlet 14. Further, the particulate matter from which the single washing decks 20 and 120 are dedusted is discharged to the venturi zone 30, and then the single discharges that are staggered in both the horizontal direction and the vertical direction with respect to the inlets 13 and 113 are provided. Exhaled at the exit. Such a staggered dust removal apparatus is illustrated and disclosed in USP 8,931,641, which was granted a patent on January 13, 2015. The contents of this publication are incorporated herein.

These changes can be implemented. The above description is to explain preferred embodiments of the present invention.
