Description

Technical Field

[0001] This invention relates to the field of talc dust recovery technology, and in particular to a dust recovery system in a talc production workshop. Background Technology

[0002] Talc is an industrial product commonly used as a filler in plastic and paper products. During the production of talc, dust is easily generated, which pollutes the production workshop and seriously affects the health of production workers. Therefore, a dust recovery system needs to be installed in the talc production workshop to reduce the dust content in the air.

[0003] Patent CN218980834U discloses a dust recovery system for a talc powder production workshop. This system includes a base, with a first telescopic rod fixed inside. A first spring is installed on the outer side of the first telescopic rod, and a dust recovery box is fixed to the end of the first telescopic rod. A fan is installed inside the dust recovery box, and a second telescopic rod is fixed to the bottom inner side of the dust recovery box. A second spring is installed on the outer side of the second telescopic rod, and a fixing plate is installed at the end of the second telescopic rod. A filter screen is fixed in the middle of the fixing plate. This dust recovery system, through the cooperation of a cam and a second spring, causes the fixing plate and the filter screen to continuously reciprocate vertically. The dust on the filter screen is shaken off and falls into the collection box, preventing the filter screen from becoming clogged. However, cleaning the dust on the filter screen by shaking only removes some of the floating dust; this method is ineffective for dust adhering to the filter screen.

[0004] Therefore, we propose a dust recovery system for talcum powder production workshops that can scrape off and remove dust from filter screens, thereby improving the cleaning effect. Summary of the Invention

[0005] In order to overcome the shortcomings of the method of shaking off dust by moving the filter screen up and down, which can only remove floating dust and has poor cleaning effect, the present invention provides a dust recovery system in the talcum powder production workshop that can scrape off and remove dust from the filter screen and improve the cleaning effect.

[0006] This invention is implemented through the following technical means: a dust recovery system in a talc powder production workshop, comprising a box, the box being connected to symmetrically arranged air inlet pipes, a collection box fixedly connected to the box, a suction device fixedly connected to the box and connected to the box, and a filter plate fixedly connected to the box. The system is characterized by further including a motor, the motor being fixedly connected to the box, a first lead screw rotatably connected to the box, the first lead screw being connected to the output shaft of the motor, a first guide rod fixedly connected to the side of the box away from the first lead screw, a sliding plate slidably connected to the first guide rod, the sliding plate being threadedly connected to the first lead screw, a rotating shaft rotatably connected to the sliding plate, a scraper plate fixedly connected to the rotating shaft, a motor embeddedly fixedly connected to the sliding plate, the output shaft of the motor being connected to the rotating shaft, and a cleaning mechanism for unblocking the filter plate provided in the box.

[0007] As a further preferred embodiment, the unblocking mechanism includes a second lead screw, which is rotatably connected to the housing. A second guide rod is fixedly connected to the side of the housing away from the second lead screw. A moving block is slidably connected to the second guide rod. The second lead screw is threadedly connected to the same moving block. Unblocking wheels are rotatably connected between the moving blocks. The housing is provided with a transmission assembly for driving the second lead screw to rotate.

[0008] As a further preferred option, the surface of the dredging wheel is provided with protrusions that mate with the filter holes of the filter plate.

[0009] As a further preferred embodiment, the transmission assembly includes a connecting rod that is rotatably connected to the housing. Both the connecting rod and the output shaft of the motor are fixedly connected to bevel gears that mesh with each other. The second lead screw and the connecting rod are connected to a flat belt via a pulley.

[0010] As a further preferred embodiment, it also includes a cleaning mechanism for cleaning the corners of the filter plate. The cleaning mechanism is located on the sliding plate and includes a pull rope connected to one side of the sliding plate. Several guide wheels are fixedly connected to the housing. The pull rope first passes out of the housing, then passes around the guide wheels in sequence, and finally passes into the housing and connects to the other side of the sliding plate. An electrostatic adsorption block is fixedly connected to the pull rope.

[0011] As a further preferred embodiment, it also includes a dust collection mechanism for absorbing dust from the cleaning wheel. The dust collection mechanism is mounted on the moving block and includes symmetrically arranged connecting blocks. The symmetrically arranged connecting blocks are fixedly connected to the moving block, and an adsorption frame is connected between the symmetrically arranged connecting blocks. The adsorption frame is connected to an air guide pipe with a one-way valve. The air guide pipe passes through the housing and its tail end is connected to the housing.

[0012] As a further preferred embodiment, it also includes a vibration mechanism for controlling the vibration of the filter plate. The vibration mechanism is disposed on the filter plate and includes equidistantly distributed pressure blocks. The equidistantly distributed pressure blocks are fixedly connected to the filter plate. A guide frame is fixedly connected to the housing. A slide is slidably connected to the guide frame. The slide is connected to a pull rope. A protrusion is slidably connected to the slide. The protrusion and the pressure blocks are in a pressing fit. A first spring is connected between the protrusion and the slide.

[0013] As a further preferred embodiment, it also includes a scraping mechanism for scraping off residual dust inside the air inlet duct. The scraping mechanism is located in the housing and includes symmetrically arranged scraping rings. The symmetrically arranged scraping rings are slidably connected to the air inlet duct of the housing. The scraping rings are fixedly connected to a connecting frame. The connecting frame is slidably connected to an adjacent air inlet duct. A second spring is connected between the connecting frame and the adjacent air inlet duct. The housing is provided with a pressing component for pressing the connecting frame to slide.

[0014] As a further preferred embodiment, the extrusion assembly includes a third guide rod, a sliding frame, a third spring, and an extrusion plate. The extrusion assembly includes symmetrically arranged third guide rods, which are fixedly connected to the housing. The third guide rods are slidably connected to the sliding frame. The sliding plate is extruded and engaged with the sliding frame. A third spring connects the sliding frame to the adjacent third guide rod. The sliding frame is fixedly connected to the extrusion plate.

[0015] As a further preferred embodiment, the side of the extrusion plate closest to the connecting frame is inclined outward, and the side of the connecting frame closest to the extrusion plate is protruding, with the extrusion plate and the adjacent connecting frame engaging in an extrusion fit.

[0016] The present invention has the following advantages: 1. The filter plate filters the dust in the air, and the scraper moves to the right to scrape off the dust adhering to the lower side of the filter plate. At the same time as the scraper moves to the right, the unblocking wheel also moves backward. The unblocking wheel rotates while moving backward, and the protrusions on the unblocking wheel unblock the filter plate, thus preventing dust from clogging the filter holes of the filter plate.

[0017] 2. The sliding plate slides left and right, and the pull rope drives the electrostatic adsorption block to move back and forth, thus adsorbing the dust on the left corner of the filter plate.

[0018] 3. When the airflow enters the adsorption frame, the dust adhering to the cleaning wheel will also be carried into the adsorption frame, thereby cleaning the dust adhering to the cleaning wheel. The air entering the adsorption frame is then transported downwards through the air guide pipe to the bottom of the filter plate.

[0019] 4. The slide moves left and right, causing the protrusions to move left and right. The left and right movement of the protrusions will squeeze and cooperate with the pressure block, thereby knocking the pressure block and causing the filter plate to vibrate. The vibration of the filter plate can shake off the dust, further improving the cleaning effect of the filter plate.

[0020] 5. The extrusion plate can press the connecting frame to make the scraper ring slide inward. The inward movement of the scraper ring can remove the dust remaining in the air inlet pipe. Attached Figure Description

Detailed Implementation

[0036] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0037] Example 1: A dust recovery system in a talc powder production workshop, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a housing 1, a suction device 2, a filter plate 201, a motor 3, a first lead screw 4, a first guide rod 5, a sliding plate 6, a rotating shaft 7, a scraper 8, a motor 9, and a cleaning mechanism. The lower part of the housing 1 is connected to symmetrical front and rear air inlets. A collection box is fixedly connected to the middle of the right side of the housing 1. The suction device 2 is fixedly connected to the lower left of the housing 1, and the suction device 2 communicates with the upper left side of the housing 1. A filter plate 201 is fixedly connected to the middle of the housing 1. A motor 3 is fixedly connected to the rear left of the housing 1. A rotating mechanism is located at the rear of the housing 1. A first lead screw 4 is connected, and the left end of the first lead screw 4 is connected to the output shaft of the motor 3. A first guide rod 5 is fixedly connected to the front of the housing 1. A sliding plate 6 is slidably connected to the first guide rod 5. The rear of the sliding plate 6 is connected to the first lead screw 4 by a thread. A rotating shaft 7 is rotatably connected to the middle of the sliding plate 6. A scraper 8 is fixedly connected to the rotating shaft 7. A motor 9 is embedded and fixedly connected to the front of the sliding plate 6. The output shaft of the motor 9 is connected to the rotating shaft 7. A cleaning mechanism is provided on the housing 1, which can clean the filter plate 201.

[0038] When using the device, the operator starts the suction device 2. The suction device 2 draws air from the production workshop into the housing 1 through the air inlet pipe. The air is then conveyed upwards and filtered through the filter plate 201. When the filter plate 201 needs cleaning, the operator starts the motor 3. The output shaft of the motor 3 rotates, driving the first lead screw 4 to rotate. The rotation of the first lead screw 4 causes the sliding plate 6 to slide to the right. The sliding plate 6, by moving to the right, drives the scraper plate 8 to move to the right via the rotating shaft 7. The scraper plate 8, moving to the right, can scrape off the dust adhering to the lower side of the filter plate 201. When the scraper plate 8 moves to the right, it reaches the right side of the filter plate 201. After the filter plate 201 is positioned above the collection box, the motor 9 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 causes the scraper 8 to rotate downwards, pushing the scraped dust into the collection box. Then, the operator controls the output shaft of the motor 3 to reverse, thereby driving the sliding plate 6 and the scraper 8 to move to the left. When the scraper 8 moves to the left, it remains in the downward rotating state. When the scraper 8 moves to the left position of the filter plate 201, the motor 9 drives the rotating shaft 7 to reverse, causing the scraper 8 to rotate upwards and reset. After the device is used, the operator turns off the suction fan 2 and the motor 3.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, the unblocking mechanism includes a second lead screw 13, a moving block 1301, a second guide rod 14, an unblocking wheel 15, and a transmission assembly. The second lead screw 13 is rotatably connected to the left side of the housing 1, and the second guide rod 14 is fixedly connected to the right side of the housing 1. The moving block 1301 is slidably connected to the second guide rod 14. The same moving block 1301 is threadedly connected to the second lead screw 13. The unblocking wheel 15 is rotatably connected between the two moving blocks 1301. The unblocking wheel 15 is provided with a protrusion that cooperates with the filter holes on the filter plate 201. The housing 1 is provided with a transmission assembly for driving the second lead screw 13 to rotate.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, the transmission assembly includes a bevel gear 10, a connecting rod 11, and a flat belt 12. The connecting rod 11 is rotatably connected to the left middle position of the housing 1. The rear of the connecting rod 11 and the output shaft of the motor 3 are both fixedly connected to the bevel gear 10. The two bevel gears 10 mesh with each other. The front of the second lead screw 13 is connected to the front of the connecting rod 11 through a pulley and a flat belt 12.

[0041] When using this device, the rotation of the output shaft of the motor 3 also drives the connecting rod 11 to rotate via the bevel gear 10. The rotation of the connecting rod 11 controls the rotation of the second lead screw 13 via the flat belt 12. The rotation of the second lead screw 13 drives the moving block 1301 to move backward. The movement of the moving block 1301 drives the unclogging wheel 15 to move backward. The unclogging wheel 15 rotates as it moves backward, and the protrusions on the unclogging wheel 15 unblock the filter plate 201, preventing dust from clogging the filter holes of the filter plate 201. When the output shaft of the motor 3 reverses, the bevel gear 10 also drives the connecting rod 11 to reverse, which in turn controls the second lead screw 13 to reverse via the flat belt 12. The reversal of the second lead screw 13 drives the unclogging wheel 15 to move forward and reset via the moving block 1301. In this way, the filter plate 201 can be unblocked, preventing dust from clogging the filter holes of the filter plate 201.

[0042] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a cleaning mechanism that can clean the left corner of the filter plate 201. The cleaning mechanism includes a pull rope 16, a guide wheel 17, and an electrostatic adsorption block 18. The pull rope 16 is connected to the front right side of the sliding plate 6. The guide wheel 17 is fixedly connected to the front left, front right, and rear left sides of the middle of the box 1. The pull rope 16 passes through the right side of the box 1, then passes around the guide wheel 17 in sequence, and finally passes through the left side of the box 1 and connects to the rear left side of the sliding plate 6. An electrostatic adsorption block 18 is fixedly connected to the pull rope 16.

[0043] By setting up a cleaning mechanism, the left corner of the filter plate 201 can be cleaned, reducing dust residue on the filter plate 201. The specific operation is as follows: When the sliding plate 6 moves to the right, it pulls the rear end of the pull rope 16 to move to the right. The front end of the pull rope 16 is also fixed on the sliding plate 6. Therefore, when the sliding plate 6 moves to the right, the entire pull rope 16 will move on the guide wheel 17. The electrostatic adsorption block 18 set on the pull rope 16 will also move backward with the pull rope 16, adsorbing the dust on the left corner of the filter plate 201 through electrostatic adsorption. When the sliding plate 6 moves to the left, the sliding plate 6 will pull the front end of the pull rope 16 to move to the left, thereby causing the entire pull rope 16 to move in the opposite direction on the guide wheel 17. The electrostatic adsorption block 18 will also move forward and reset with the pull rope 16.

[0044] like Figure 1 , Figure 2 and Figure 10As shown, it also includes a dust collection mechanism, which can suck up dust from the cleaning wheel 15. The dust collection mechanism also includes a connecting block 19, an adsorption frame 20 and an air guide pipe 21. The connecting block 19 is fixedly connected to both the left and right moving blocks 1301. The adsorption frame 20 is connected between the left and right connecting blocks 19. The air guide pipe 21 with a one-way valve is connected to the middle of the adsorption frame 20. The air guide pipe 21 passes through the front side of the box 1, and the tail end of the air guide pipe 21 is connected to the lower front side of the box 1.

[0045] By setting up a dust collection mechanism, the dust adhering to the drain cleaner wheel 15 can be cleaned. The specific operation is as follows: Since the air duct 21 has a one-way valve, when the air blower 2 draws in air to make the air circulate, the airflow will only enter the suction frame 20 and be transported downward through the air duct 21 to the bottom of the filter plate 201. When the airflow enters the suction frame 20, the dust adhering to the drain cleaner wheel 15 will also be carried into the suction frame 20, thereby cleaning the dust adhering to the drain cleaner wheel 15. Under the action of the connecting block 19, the suction frame 20 will also move left and right with the drain cleaner wheel 15, thereby ensuring the cleaning effect.

[0046] like Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, it also includes a vibration mechanism that can control the vibration of the filter plate 201. The vibration mechanism includes a pressure block 22, a guide frame 23, a slide 24, a protrusion 25, and a first spring 26. Three pressure blocks 22 are fixedly connected to the front side of the filter plate 201 at equal intervals. A guide frame 23 is fixedly connected to the front side of the housing 1. A slide 24 is slidably connected to the guide frame 23. The lower part of the slide 24 is connected to the pull rope 16. A protrusion 25 is slidably connected to the upper part of the slide 24. The protrusion 25 moves left and right to contact the pressure block 22. A first spring 26 is connected between the protrusion 25 and the slide 24.

[0047] By setting a vibration mechanism, the filter plate 201 can be vibrated, thereby shaking off the dust and further cleaning the dust on the filter plate 201. The specific operation is as follows: When the pull rope 16 moves, it will drive the slide 24 to move left and right on the guide frame 23. The left and right movement of the slide 24 will drive the protrusion 25 to move left and right. Under the action of the first spring 26, the left and right movement of the protrusion 25 will squeeze and cooperate with the pressure block 22, thereby knocking the pressure block 22, causing the filter plate 201 to vibrate. The vibration of the filter plate 201 can shake off the dust and further improve the cleaning effect of the filter plate 201.

[0048] like Figure 2 , Figure 13 and Figure 14As shown, it also includes a scraping mechanism, which can scrape off the dust remaining in the air inlet pipe. The scraping mechanism includes a scraper ring 27, a connecting frame 28, a second spring 29, and a pressing assembly. The scraper ring 27 is slidably connected to the air inlet pipe of the housing 1. The connecting frame 28 is fixedly connected to the upper part of the scraper ring 27. The connecting frame 28 is slidably connected to the adjacent air inlet pipe. The second spring 29 is connected between the connecting frame 28 and the adjacent air inlet pipe. The pressing assembly is provided in the lower part of the housing 1. The pressing assembly can press the connecting frame 28 to slide inward.

[0049] Figure 13 and Figure 14 As shown, the extrusion assembly includes a third guide rod 30, a sliding frame 31, a third spring 32, and an extrusion plate 33. The lower right side of the housing 1 is fixedly connected to a symmetrical third guide rod 30. The sliding frame 31 is slidably connected to the third guide rod 30. The sliding plate 6 slides to the right, pushing the sliding frame 31 to move to the right. The sliding frame 31 is connected to the adjacent third guide rod 30 by a third spring 32. The lower part of the sliding frame 31 is fixedly connected to the extrusion plate 33. The right side of the extrusion plate 33 is inclined outward, and the inner end of the connecting frame 28 is protruding upward. The extrusion plate 33 moves to the right, pressing the adjacent connecting frame 28 to slide inward.

[0050] By setting up a scraping mechanism, residual dust inside the air inlet duct can be scraped off. The specific operation is as follows: When the sliding plate 6 slides to the right and contacts the sliding frame 31, the sliding plate 6 continues to move to the right, which will squeeze the sliding frame 31 to slide to the right. The third spring 32 deforms, and the sliding frame 31 slides to the right, causing the squeezing plate 33 to move to the right. The squeezing plate 33 moves to the right, which will squeeze the connecting frame 28 to slide inward. The second spring 29 deforms, and the connecting frame 28 slides inward, causing the scraper ring 27 to move inward. The scraper ring 27 can scrape off the residual dust inside the air inlet duct. When the sliding plate 6 slides to the left and no longer squeezes the sliding frame 31, under the action of the third spring 32 resetting, the sliding frame 31 will drive the squeezing plate 33 to move to the left. Under the action of the second spring 29 resetting, the connecting frame 28 will drive the scraper ring 27 to slide outward and reset. In this way, the residual dust inside the air inlet duct can be scraped off.
