Description

Technical Field

[0001] This invention relates to a high-efficiency dust removal device, and more particularly to a high-efficiency dust removal device for polystyrene applied in the field of dust cleaning. Background Technology

[0002] Polystyrene and its modified products, such as high-impact polystyrene (HIPS), do generate dust during production, processing, and transportation. In particular, inhalable particulate matter is easily formed in the following stages, requiring strict control measures.

[0003] Chinese invention patent CN107791291B discloses a plastic cutting machine equipped with a water spray device. On the one hand, it uses cold water to cool the cutting blade a second time. On the other hand, it uses the water entering the water pipe and the negative pressure to flush the dust in the water pipe into the recycling bin to prevent dust from clogging the water pipe. At the same time, the water spraying process can also settle any small amount of dust that may remain in the air, further effectively preventing dust from spreading and causing harm to the environment and people.

[0004] Chinese invention patent CN109747080A discloses a plastic crushing device with anti-detachment function. When the plastic is being crushed, water is sprayed out from the spray hole. Under the action of the water flow, the dust in the box is washed to the bottom of the box, reducing the impact of plastic crushing on the environment and preventing dust from affecting the health of operators.

[0005] Existing dust cleaning equipment typically sprays water during cutting to reduce dust dispersion. However, in actual operation, the surface of the finished granules after cutting and granulation carries a mixture of dust and liquid, requiring secondary cleaning to reduce dust contamination on the surface of the finished granules. During secondary rinsing, batches of finished products are usually rinsed in batches, making it impossible to perform uninterrupted feeding, rinsing, and discharging operations while ensuring cleaning quality. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to carry out efficient and continuous cleaning treatment on the surface of polystyrene granules after granulation, while ensuring that the amount of dust is reduced during the processing of polystyrene granules, so as to prevent the dust remaining on the surface of the granules from drying and spreading again during subsequent transportation.

[0007] To address the aforementioned problems, this invention provides a high-efficiency dust removal device for polystyrene, comprising a granulator containing a granulation chamber, a water spray pipe installed through the top of the granulation chamber, a treatment box installed on one side of the granulator via a bracket, a negative pressure conveying pump arranged below the granulation chamber, the negative pressure conveying pump being connected to the interior of the treatment box via a transfer pipe, a secondary filter plate and a primary filter plate arranged vertically on the inner wall of the treatment box, a top cover plate with a hollow interior being installed on the top of the treatment box, and multiple spray nozzles installed through the bottom of the top cover plate;

[0008] Two electric extension rods are installed on the top of the top cover plate. Inside the treatment box, there is a variable filter unit located above the secondary filter plate. The variable filter unit includes a middle filter plate that is movably connected to the movable end of the electric extension rod. Variable shafts are rotatably connected to both sides of the middle filter plate. Side filter plates are fixedly connected to the surface of the variable shafts, and the surface of the side filter plates facing away from the variable shafts is tapered.

[0009] A discharge pipe is installed through one side of the processing box, and a movable component is arranged on the side of the filter plate near the discharge pipe. An adjustment groove for accommodating the up-and-down movement of the variable shaft is provided through the other side of the processing box, and a drive component is installed on the outside of the adjustment groove.

[0010] In the aforementioned high-efficiency dust removal device for polystyrene, the central filter plate and the rotatable side filter plate are driven by an electric extension rod to form a triangular enclosure structure, thereby realizing the mechanical transfer of particles on the surface of the secondary filter plate and solving the secondary pollution problem caused by traditional fixed filter plates.

[0011] As a further improvement of this application, the active component includes an active strip, and the side filter plate has a groove on the side near the discharge pipe. The cross-section of the active strip matches the groove. The interior of the groove is connected to the surface of the active strip by an elastic element. In the initial state, the side surface of the active strip away from the elastic element is in contact with the inner wall of the processing box.

[0012] As a further improvement of this application, the drive assembly includes a drive motor, and the surfaces of the portions of the two variable shafts extending out of the adjustment grooves are fitted with mutually meshing drive gears. A vertical plate is arranged outside the drive gears, and the output end of the drive motor is connected to the surface of one of the drive gears.

[0013] As a further improvement of this application, a suction pump is installed on the side of the processing box where the discharge pipe is installed, and the input end of the suction pump is connected to a flexible hose located below the primary filter plate, and the output end of the suction pump is connected to the top cover plate through a water pipe.

[0014] As a further improvement of this application, the cross-sectional width of the discharge pipe is not greater than the cross-sectional width of the middle filter plate, and the bottom end of the adjustment trough is located above the interface between the transfer pipe and the treatment box. The end of the variable shaft is fitted with an elastic sealing sheet through a bearing, and the ends of the elastic sealing sheet are respectively connected to the top wall and the bottom wall of the adjustment trough.

[0015] As a further improvement of this application, a cleaning auxiliary system is also included. The cleaning auxiliary system includes a displacement sensor installed on the middle filter plate and a pressure sensor installed in the side filter plate. Both the displacement sensor and the pressure sensor are connected to the drive motor and the electric extension rod for signal monitoring of the position status of the middle filter plate and the side filter plate in the processing box, and indirectly adjusting the placement status of the side filter plate. The cleaning auxiliary system also includes a change processing module for adjusting the lifting amplitude of the electric extension rod during the process of the side filter plate moving from bottom to top to be horizontal with the middle filter plate.

[0016] As a further improvement of this application, the filtration diameters of the middle filter plate, the side filter plate, and the secondary filter plate are the same and all smaller than the filtration diameter of the primary filter plate.

[0017] As another improvement of this application, the secondary filter plate is composed of a horizontal part and an arc-shaped part, wherein the length of the horizontal part is the same as the length of the middle filter plate, the radius of curvature of the arc-shaped part is the same as the length of the side filter plate when it is placed vertically, and the arc-shaped part is a quarter circle.

[0018] As a further improvement to this application, the inner wall of the treatment box is provided with a matching groove, and the tail end of the arc-shaped portion is embedded in the matching groove, and the top of the arc-shaped portion of the secondary filter plate is flush with the inner wall of the treatment box.

[0019] As a further improvement to this application, the primary filter plate has an arc-shaped design, and an ultrasonic transducer is installed inside the primary filter plate. A dust collection pipe is rotatably installed on the surface of the primary filter plate at its center, and the tail end of the dust collection pipe extends through to the outside of the treatment box. A closed cover located on the outer periphery of the dust collection pipe is connected to the surface of the primary filter plate by a fixing rod, and the closed cover and the dust collection pipe are designed as concentric circles. Two arc-shaped feed pipes are installed on the surface of the dust collection pipe, and the curvature of the feed pipes is the same as that of the middle part of the primary filter plate. The feed pipes are in close contact with the inner wall of the closed cover by rotation.

[0020] In summary, by using an electric extension rod to drive the central filter plate and the rotatable side filter plate to form a triangular enclosure structure, mechanical transfer of particles on the surface of the secondary filter plate is achieved, solving the secondary pollution problem caused by traditional fixed filter plates. Furthermore, the secondary filter plate is designed as a combination of a horizontal axis and a 1 / 4 arc, allowing the side filter plates to continue circulating material even in a vertical position. This specific curvature radius and filter plate length matching solves the technical problem of material leakage during transfer. Finally, a rotating dust collection pipe combined with a segmented ultrasonic transducer design, using the alternating opening and closing of the feed pipe and the enclosed hood, achieves directional cleaning. This technical solution is innovative in the field of dust treatment, especially solving the dust problem caused by traditional vibration cleaning. Attached Figure Description

[0036] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] First implementation method:

[0038] Figures 1-3 A high-efficiency dust removal device for polystyrene is shown, including a granulator 1 containing a granulation chamber 101, a water spray pipe 102 installed through the top of the granulation chamber 101, a treatment box 2 installed on one side of the granulator 1 via a bracket, a negative pressure conveying pump arranged below the granulation chamber 101, and the negative pressure conveying pump connected to the inside of the treatment box 2 via a transfer pipe, a secondary filter plate 6 and a primary filter plate 5 arranged vertically are fixedly installed on the inner wall of the treatment box 2, and a top cover plate with a hollow interior is installed on the top of the treatment box 2, and multiple nozzles are installed through the bottom of the top cover plate;

[0039] Figure 4 The top of the top cover plate is shown to be equipped with two electric extension rods 10. Inside the processing box 2, there is a variable filtration unit 7 located above the secondary filter plate 6. The variable filtration unit 7 includes a central filter plate 71 that is movably connected to the movable end of the electric extension rods 10. Variable shafts 74 are rotatably connected to both sides of the central filter plate 71. Side filter plates 72 are fixedly connected to the surface of the variable shafts 74. The surface of the side filter plates 72 facing away from the variable shafts 74 is tapered (not fixed, the shape of this part can be changed according to actual needs).

[0040] A discharge pipe 4 is installed through one side of the processing box 2. A movable component is arranged on the side of the side filter plate 72 near the discharge pipe 4. An adjustment groove 9 for accommodating the up and down movement of the variable shaft 74 is provided through the other side of the processing box 2, and a drive component is installed on the outside of the adjustment groove 9.

[0041] A suction pump 3 is installed on the side of the processing box 2 where the discharge pipe 4 is installed. The input end of the suction pump 3 is connected to a flexible hose located below the primary filter plate 5, and the output end of the suction pump 3 is connected to the top cover plate through a water pipe.

[0042] Specifically, to reduce dust during polystyrene processing, the formulation of polystyrene processing raw materials can be improved. Adding auxiliary materials can increase the wear resistance of the product surface and improve the integrity of the fracture surface of finished particles, thereby reducing the total amount of fine powder generated from the source. Internal lubricants and other related auxiliary materials can be added.

[0043] During the granulation process, the granulation chamber 101 is dusted by spraying water pipe 102. The polystyrene particles in the granulation chamber 101 carry the dust mixture into the surface of the secondary filter plate 6 through the transfer pipe for preliminary filtration. After the dust mixture is filtered by the primary filter plate 5, the filtered clear liquid is transferred to the top cover plate through water pipe, suction pump 3 and hose. The particles on the surface of the secondary filter plate 6 are then cleaned a second time by the nozzles in the top cover plate, which can wash away the dust remaining on the surface of the particles after preliminary filtration.

[0044] However, since the negative pressure conveying pump continuously feeds, the particles on the surface of the secondary filter plate 6 after the second cleaning will be contaminated by the new feed, resulting in poor secondary cleaning effect. To improve this phenomenon, the secondary cleaning operation is separated from the primary filtration operation, which can not only ensure the stability of the secondary cleaning quality, but also ensure that the discharge operation and the feeding operation do not interfere with each other.

[0045] Figure 6 As shown, when the variable filter unit 7 is used for corresponding operation, the middle filter plate 71 and the side filter plate 72 are both in a horizontal state. At this time, the drive motor 8 is used first. Through the meshing of the drive gear, the two variable shafts 74 can be rotated, so that the ends of the two side filter plates 72 move away from the ends of the variable shafts 74 (the movement path is arc-shaped). This makes the two side filter plates 72 and the middle filter plate 71 form a triangle. Since the two side filter plates 72 have the same length, the tips of the two side filter plates 72 after closing are located in the middle position of the secondary filter plate 6. When the ends of the side filter plates 72 close to form tips, the tapered design helps to reduce the tip area.

[0046] Then, the electric extension rod 10 is activated, causing the variable filter unit 7, which is in a variable enclosed state, to descend until its tip contacts the surface of the secondary filter plate 6. At this point, the tip inserts into the pre-filtered particle pile accumulated on the surface of the secondary filter plate 6. Then, the drive motor 8 rotates in the opposite direction, causing the two enclosed side filter plates 72 to gradually move upwards until the side filter plates 72 are horizontal with the middle filter plate 71 (or it could be a path like this: tip --- outward expansion and lifting --- horizontal --- closing at the top --- horizontal again, etc.). Figure 7 As shown, the path design is not fixed. The main purpose of closing at the top is to better transfer the particles on the surface of the side filter plate 72 to the surface of the middle filter plate 71. During this process, the particles accumulated on the surface of the secondary filter plate 6 can be gradually transferred to the surfaces of the middle filter plate 71 and the side filter plate 72 to achieve the transfer operation. After that, the horizontally oriented variable filter unit 7 is raised and the nozzle performs a secondary cleaning.

[0047] After the second cleaning is completed, the drive motor 8 is started again, causing the two side filter plates 72 to form a U-shape. Then, the electric extension rod 10 on the side opposite to the discharge pipe 4 is started to continue lifting (e.g. Figure 5 As shown, due to the design of the adjustment groove 9, the inclined variable shaft 74 has corresponding operating space, and the discharge port of the inclined U-shaped variable filter unit 7 can contact the inlet of the discharge pipe 4. Then, with the cooperation of the movable components, the particles after secondary cleaning can be discharged (in this state, there is still a gap between the variable shaft 74 and the top of the adjustment groove 9 to allow for the tilt adjustment of the variable shaft 74).

[0048] During the process of the variable filtration unit 7 removing the pre-filtered particles from the surface of the secondary filter plate 6 and lifting it to receive secondary cleaning and subsequent discharge operations, the secondary filter plate 6 can continue to receive the particle and dust mixture conveyed by the transfer pipe and be cleaned with the solution after secondary cleaning.

[0049] The drive assembly includes a drive motor 8, and two variable shafts 74 with meshing drive gears fitted onto the surfaces of the portions extending out of the adjustment groove 9. A vertical plate is arranged outside the drive gears, and the output end of the drive motor 8 is connected to the surface of one of the drive gears.

[0050] Specifically, the drive motor 8 drives two drive gears to move, which in turn indirectly drives two variable shafts 74 to rotate, thereby achieving the adjustment of the corresponding side filter plates 72.

[0051] The movable component includes a movable strip 73. The side filter plate 72 has a groove on the side near the discharge pipe 4, and the cross section of the movable strip 73 matches the groove. The inside of the groove is connected to the surface of the movable strip 73 through an elastic element. In the initial state, the side surface of the movable strip 73 facing away from the elastic element is in contact with the inner wall of the processing box 2.

[0052] Specifically, when the variable filter unit 7 is discharging material, since the variable filter unit 7 in the horizontal state and the processing box 2 have the same inner cross section, and since the side filter plate 72 is folded upward to form a U-shaped structure, if a tilting operation is required, the movable strip 73 will be deformed and squeezed into the groove due to the obstruction and restriction of the inner wall of the processing box 2, so that the tilting operation can be carried out smoothly.

[0053] The cross-sectional width of the discharge pipe 4 is not greater than the cross-sectional width of the middle filter plate 71, and the bottom end of the adjusting groove 9 is located above the interface between the transfer pipe and the treatment box 2. The end of the variable shaft 74 is fitted with an elastic sealing sheet (not shown in the figure) through a bearing sleeve, and the ends of the elastic sealing sheet are connected to the top wall and bottom wall of the adjusting groove 9 respectively.

[0054] Specifically, the design of the adjusting groove 9 not only provides the corresponding space for the lifting and lowering movement of the variable shaft 74, but also prevents material from leaking out through the adjusting groove 9 when the transfer pipe is feeding. It also prevents the vertical plate from being blocked by the transfer pipe when it descends to the bottom of the adjusting groove 9. To enhance the sealing effect of the adjusting groove 9, the elastic sealing sheet is not affected when the variable shaft 74 rotates, and can supplement the sealing treatment of the adjusting groove 9 with the movement of the variable shaft 74.

[0055] It also includes a cleaning auxiliary system, which includes a displacement sensor installed on the middle filter plate 71 and a pressure sensor installed in the side filter plate 72. Both the displacement sensor and the pressure sensor are connected to the drive motor 8 and the electric extension rod 10 for monitoring the position of the middle filter plate 71 and the side filter plate 72 in the processing box 2 and indirectly adjusting the placement of the side filter plate 72. The cleaning auxiliary system also includes a change processing module for adjusting the lifting amplitude of the electric extension rod 10 during the process of the side filter plate 72 moving from bottom to top to be horizontal with the middle filter plate 71.

[0056] Specifically, while the side filter plate 72 moves in an arc shape, the electric extension rod 10 should also be raised slightly at the same time. This is because if the electric extension rod 10 does not change its height accordingly during the arc movement of the end of the side filter plate 72 away from the variable shaft 74 to the horizontal rotation, the end of the side filter plate 72 away from the variable shaft 74 will be blocked by the secondary filter plate 6. Therefore, the lifting height of the electric extension rod 10 during the above process can be adjusted in conjunction with the variable processing module to ensure the smooth operation of the corresponding operation.

[0057] Second implementation method:

[0058] Figures 9-10The secondary filter plate 6 is shown to consist of a horizontal part and an arc-shaped part. The length of the horizontal part is the same as the length of the middle filter plate 71, and the radius of curvature of the arc-shaped part is the same as the length of the side filter plate 72 when it is placed vertically. The arc-shaped part is a quarter circle.

[0059] The inner wall of the treatment box 2 is provided with a matching groove, and the tail end of the arc-shaped part is embedded in the matching groove. The top of the arc-shaped part of the secondary filter plate 6 is flush with the inner wall of the treatment box 2.

[0060] The primary filter plate 5 has an arc-shaped design, and an ultrasonic transducer is installed inside the primary filter plate 5. A dust collection pipe 12 is rotatably installed on the surface of the primary filter plate 5 at its center position, and the tail end of the dust collection pipe 12 extends through to the outside of the treatment box 2. The surface of the primary filter plate 5 is connected to a closed cover 11 located on the outer periphery of the dust collection pipe 12 by a fixing rod, and the closed cover 11 and the dust collection pipe 12 are designed as concentric circles. Two arc-shaped feed pipes 13 are installed on the surface of the dust collection pipe 12, and the curvature of the feed pipes 13 is the same as the curvature of the middle part of the primary filter plate 5. The feed pipes 13 are in close contact with the inner wall of the closed cover 11 by rotation.

[0061] Unlike the first embodiment, this embodiment adjusts the shape of the secondary filter plate 6 to make the edge filter plate 72 more efficient at circling particles on the surface of the secondary filter plate 6. In this embodiment, the end of the dust collection pipe 12 is connected to a pump body for sucking up blockages and a servo motor for driving the dust collection pipe 12 to rotate (both are prior art and not shown in the figure), and the middle of the sealing cover 11 and the primary filter plate 5 are provided with a small cross-section.

[0062] Specifically, in the first embodiment, when the edge filter plate 72 rotates in an arc to a vertical position, its contact with the secondary filter plate 6 reaches a boundary transition state. If the arc movement continues, a gap will exist between the end of the edge filter plate 72 and the secondary filter plate 6, causing omissions in the transfer of material on the surface of the secondary filter plate 6 (e.g., Figure 8 (As shown), to improve this phenomenon, the secondary filter plate 6 is modified so that when the edge filter plate 72 continues its arc-shaped movement after moving to a vertical position, it can continue to circulate the material on the surface of the secondary filter plate 6, thereby achieving a perfect material transfer operation and avoiding omissions (such as...). Figure 11 (As shown).

[0063] Furthermore, when cleaning the surface of the primary filter plate 5, the servo motor is first used to rotate the dust collection pipe 12 by a certain amplitude, so that the bottom of one of the feed pipes 13 is in contact with the surface of the primary filter plate 5. Then, the ultrasonic transducer on one side is activated (because of the break, the other part of the primary filter plate 5 will not shake, and the break on the surface of the primary filter plate 5 is located in the middle, so the surface of the primary filter plate 5 and the lowest point of the dust collection pipe 12 are in a non-contact state, so even if one side of the primary filter plate 5 is vibrated, it will not be transmitted to the other side). This can remove the blockage through vibration. The blockages on the surface of the primary filter plate 5 are shaken and rolled off. The blockages on this side are collected. Then, the plate is rotated in the opposite direction by a corresponding amount, so that the feed pipe 13 is in contact with the inner wall of the sealing cover 11, and the other feed pipe 13 is in contact with the surface of another part of the primary filter plate 5. This process is repeated until the blockages on both parts of the primary filter plate 5 are collected. Then, the dust collection pipe 12 is rotated until both feed pipes 13 are sealed with the sealing cover 11. Finally, the pump is started to suck out the blockages from the dust collection pipe 12, completing the cleaning of the primary filter plate 5. Figures 12-13 (As shown).

[0064] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
