A dust treatment device for a plate-making workshop Technical Field

[0001] This application relates to the field of dust control, and more particularly to a dust control device for a plate-making workshop. Background Technology

[0002] The plate-making workshop refers to the workshop where printing rollers are manufactured. Currently, the manufacturing process of printing rollers is as follows: steel roller blank (seamless steel pipe or rolled plate) - machining (plugging, rough machining, fine machining) - copper plating (cleaning, electrolytic degreasing, nickel plating, copper plating, grinding, polishing) - electro-engraving (assembling large plates, engraving) - chrome plating (cleaning, degreasing, chrome plating, polishing).

[0003] When printing rollers are in production, multiple machines operate simultaneously, generating a large amount of dust. This dust floats in the air and is difficult to remove, thus affecting the health of operators. Summary of the Invention

[0004] In order to remove dust from the printing roller workshop and minimize the impact on the health of operators, this application provides a dust treatment device for the printing roller workshop.

The blower duct extends along the length of the workshop and is fixedly connected to the end of the corresponding side wall of the workshop away from the ground. The blower duct has multiple blower holes and is connected to the air outlet of the blower.

[0009] By adopting the above technical solution, the operation of the blower allows outside air to enter the workshop through the blower duct and blower hole; the operation of the suction fan discharges the dust in the workshop through the suction duct, thereby achieving the purpose of removing dust from the printing roller workshop and minimizing the impact on the health of operators; the relative arrangement of the blower duct and suction duct creates an air curtain above the workshop, allowing the air in the workshop to carry dust and other impurities into the air curtain, thus accelerating the removal of dust from the workshop.

Detailed Implementation

[0056] The present application will be further described in detail below with reference to Figures 1-7, and the present application is described with reference to a rectangular workshop for plate making.

[0057] This application discloses a dust treatment device for a plate-making workshop. Referring to FIG1, the dust treatment device includes a suction assembly 200, a blower assembly 300, and a filter assembly.

[0058] The suction assembly 200 includes a suction fan 210 and a suction duct 220. The suction fan 210 is fixedly connected to the outer wall of the workshop 100. One end of the suction duct 220 is connected to the suction end of the suction fan 210, and the other end extends into the workshop 100 and extends along the length of the workshop 100. The suction duct 220 has multiple suction holes 221, which are arranged sequentially along the length of the suction duct 220.

[0059] The air blowing assembly includes a blower 310 and a blower duct 320. The blower 310 is fixedly connected to the outer wall of the workshop 100. One end of the blower duct 320 is connected to the air outlet of the blower 310, and the other end passes into the workshop 100 and extends along the length of the workshop 100. The blower duct 320 has multiple air holes 321, and the multiple air holes 321 are arranged sequentially along the length of the blower duct 320.

[0060] To accelerate the dust removal speed in workshop 100, the suction duct 220 and the blower duct 320 are respectively located on both sides of workshop 100, and both the suction duct 220 and the blower duct 320 are fixedly connected to the inner wall of workshop 100 on the corresponding side. The relative arrangement of the suction duct 220 and the blower duct 320 causes an air curtain to be formed between the blower duct 310 and the suction duct 220 after the blower 310 and the suction fan 210 are running. This causes the air in workshop 100 to carry dust and flow away from the ground, and finally be discharged to the outside through the suction duct 220.

[0061] In order to quickly remove the dust generated by the machine, each part of the equipment that generates dust can be equipped with a dust removal pipe. One end of the dust removal pipe is fixedly connected to the equipment, and the other end extends between the blower pipe 320 and the suction pipe 220, so that the end of the dust removal pipe close to the equipment forms a negative pressure and quickly sucks up the dust generated by the equipment.

[0062] Referring to Figures 1, 2, and 3, to reduce heat loss in workshop 100 during winter and cool air loss in workshop 100 during summer, the air inlet of blower 310 and the air outlet of suction fan 210 are connected by a connecting pipe 400. To conserve energy, the middle section of the connecting pipe 400 is located inside workshop 100 and is fixedly connected to the inner wall of workshop 100. A filter assembly is located inside the connecting pipe 400 to filter the air inside workshop 100.

[0063] The filter assembly includes multiple activated carbon blocks 410, which are arranged sequentially along the length of the connecting pipe 400, and the activated carbon blocks 410 are located on the portion of the connecting pipe 400 located within the workshop 100.

[0064] Referring to Figures 2 and 3, activated carbon blocks 410 are prone to failure after prolonged use. Therefore, in order to facilitate timely detection of the operation of the filter components by staff, an air detection sensor is installed in the blower duct 320 to detect the air purification status in the blower duct 320, and a replacement component 500 for replacing activated carbon blocks 410 is installed on the connecting pipe 400.

[0065] The replacement component 500 includes a container 510, a feeding rack 520, a discharging rack 530, a first pusher rack 540, and a second pusher rack 550. The container 510 is fixedly connected to the ground side of the connecting pipe 400 and is also fixedly installed on the inner wall of the workshop 100. An opening is provided on one side of the container 510 to facilitate the replacement of activated carbon blocks 410 by workers. A door for opening and closing the opening is rotatably connected to the container 510. The ground side wall of the connecting pipe 400 has a feeding port 420 and a discharging port 430 communicating with the container 510. The feeding port 420 and the discharging port 430 are located on both sides of the filter component, and are arranged sequentially along the airflow direction inside the connecting pipe 400.

[0066] Both the feeding rack 520 and the unloading rack 530 are rectangular frames. The activated carbon block 410 can be inserted into the rectangular frame so that the feeding rack 520 and the unloading rack 530 can move the activated carbon block 410.

[0067] The loading rack 520 is located on the side of the loading port 420 closest to the ground, and the loading rack 520 can abut against the side wall of the loading port 420, thereby making it difficult for air inside the connecting pipe 400 to enter the containing box 510. The loading rack 520 can move in a direction close to or away from the connecting pipe 400, thereby allowing the loading rack 520 to enter and exit the connecting pipe 400 through the loading port 420.

[0068] The unloading rack 530 is located on the side of the unloading port 430 closest to the ground, and the unloading rack 530 can abut against the side wall of the unloading port 430, thereby making it difficult for air inside the connecting pipe 400 to enter the containing box 510. The unloading rack 530 can move in a direction close to or away from the connecting pipe 400, thereby allowing the unloading rack 530 to enter and exit the connecting pipe 400 through the unloading port 430.

[0069] The receiving box 510 is equipped with a sliding assembly 600 for driving the loading rack 520 and the unloading rack 530 to slide. Two sets of sliding assemblies 600 are provided, one set connected to the loading rack 520 to drive the loading rack 520 to move, and the other set connected to the unloading rack 530 to drive the unloading rack 530 to move. This embodiment uses the sliding assembly 600 connected to the loading rack 520 as an example for explanation.

[0070] The sliding assembly 600 includes at least one sliding gear 620 and one sliding rack 610. In this embodiment, three sliding gears 620 and three sliding racks 610 are provided, arranged sequentially along a direction perpendicular to the length of the connecting pipe 400. The three sliding gears 620 are coaxially arranged and rotatably connected to the inner wall of the workshop 100, and the three sliding racks 610 are fixedly connected to the side of the loading rack 520 near the ground, and the sliding gears 620 and sliding racks 610 in the same group mesh with each other.

[0071] The housing 510 is equipped with a drive assembly 630 for synchronously rotating the sliding gears 620 corresponding to the loading rack 520 and the unloading rack 530. The drive assembly 630 includes a drive motor 631, a drive roller 632, a drive belt 633, and a transmission roller 634. The drive motor 631 is fixedly connected to the inner wall of the workshop 100 and is electrically connected to an air detection sensor. The drive roller 632 is coaxially fixedly connected to the output shaft of the drive motor 631 and coaxially fixedly connected to the sliding gear 620 corresponding to the loading rack 520. The transmission roller 634 is rotatably connected to the inner wall of the workshop 100 and coaxially fixedly connected to the sliding gear 620 corresponding to the unloading rack 530. The drive roller 632 and the transmission roller 634 are connected by the drive belt 633.

[0072] Start the drive motor 631, which in turn drives the drive roller 632 to rotate, causing the sliding gear 620 corresponding to the loading rack 520 to rotate. Simultaneously, the drive belt 633 drives the transmission roller 634 to rotate, causing the sliding gear 620 corresponding to the unloading rack 530 to rotate. When the sliding gear 620 corresponding to the loading rack 520 rotates, its corresponding sliding rack 610, under the action of the sliding gear 620, moves the loading rack 520 away from the ground, i.e., the loading rack 520 passes through the loading port 420 and enters the connecting pipe 400. When the sliding gear 620 corresponding to the unloading rack 530 rotates, its corresponding sliding rack 610, under the action of the sliding gear 620, moves the unloading rack 530 away from the ground, i.e., the unloading rack 530 passes through the unloading port 430 and enters the connecting pipe 400.

[0073] Both the first pusher 540 and the second pusher 550 are pusher plates, and multiple weight-reducing holes are provided on the pusher plates. The first pusher 540 is connected to the inner wall of the connecting pipe 400, and the first pusher 540 can move along the length of the connecting pipe 400 to push the activated carbon block 410 on the feeding rack 520 down, that is, to push the activated carbon block 410 on the feeding rack 520 towards the lower feed port 430. A first moving component 700 for driving the first pusher 540 to move is provided on the connecting pipe 400.

[0074] The first moving component 700 includes a first moving hydraulic tank 710 and a first moving hydraulic piston 720. The first moving hydraulic tank 710 is fixedly connected to the inner wall of the connecting pipe 400, the first moving hydraulic piston 720 is sealed and slidably connected to the first moving hydraulic tank 710, and the first pusher frame 540 is fixedly connected to the side of the first moving hydraulic piston 720 away from the first moving hydraulic tank 710.

[0075] A first regulating component 730 for driving the first movable hydraulic piston 720 to slide is provided on the connecting pipe 400. The first regulating component 730 includes a first regulating cylinder 732 and a first regulating piston 731. The first regulating cylinder 732 is fixedly connected to the side of the connecting pipe 400 away from the receiving box 510 and communicates with the first movable hydraulic tank 710. The first regulating piston 731 passes through the side wall of the connecting pipe 400 and is connected to the feeding rack 520. The first regulating piston 731 and the first regulating cylinder 732 are in a sealed sliding connection. Both the first regulating cylinder 732 and the first movable hydraulic tank 710 contain hydraulic oil. When the feeding rack 520 moves away from the ground, the oil pressure in the first regulating cylinder 732 rises, causing the hydraulic oil in the first regulating cylinder 732 to flow into the first movable hydraulic tank 710, and the first movable hydraulic piston 720 slides towards the discharge port 430.

[0076] Referring to Figures 3 and 4, in order to prevent the feeding rack 520 from interfering with the first pushing rack 540, a first liquid storage cylinder 740 is fixedly connected to the side of the connecting channel away from the ground. A first liquid storage piston 741 is provided inside the first liquid storage cylinder 740. The first liquid storage piston 741 is sealed and slidably connected to the first liquid storage cylinder 740. A first return spring 742 is provided inside the first liquid storage cylinder 740. One end of the first return spring 742 is fixedly connected to the bottom of the first liquid storage cylinder 740, and the other end is fixedly connected to the first liquid storage piston 741. Under the elastic force of the first return spring 742, the first liquid storage piston 741 retracts into the first liquid storage cylinder 740. The first liquid storage cylinder 740 is connected to the first movable hydraulic tank 710 through the first connecting pipe 711, and the first connecting pipe 711 is provided with a first on / off valve 744. The first on / off valve 744 is a push-button type, and the first on / off valve 744 is fixedly connected to the inner wall of the connecting pipe 400 away from the accommodating box 510, and is located on the moving trajectory of the feeding rack 520, so that the first on / off valve 744 can be pushed to open when the feeding rack 520 moves upward.

[0077] The first liquid storage tank 740 and the first regulating tank 732 are connected by a first connecting pipe 743. A one-way valve is provided on the first connecting pipe 743 to allow the hydraulic oil in the first regulating tank 732 to flow unidirectionally into the first liquid storage tank 740. The first movable hydraulic tank 710 and the first regulating tank 732 are connected by a first connecting pipe 712. A one-way valve is provided on the first connecting pipe 712 to allow the liquid in the first movable hydraulic tank 710 to flow unidirectionally into the first regulating tank 732.

[0078] Referring to Figures 3 and 5, to further prevent interference between the feeding rack 520 and the first pusher rack 540, the moving distance of the first regulating piston 731 is no greater than 1 / 2 of the moving distance of the feeding rack 520. The feeding rack 520 is detachably connected to the first regulating piston 731. A first groove 521 is provided on the feeding rack 520, and a first sliding groove 522 is provided on the side wall of the first groove 521. A first sliding block 523 and a first sliding spring 524 are provided in the first sliding groove 522. One end of the first sliding spring 524 is fixedly connected to the bottom of the first sliding groove 522, and the other end is fixedly connected to the first sliding block 523. Under the elastic force of the first sliding spring 524, the first sliding block 523 extends out of the first sliding groove 522, and the part of the first sliding block 523 extending out of the first sliding groove 522 is hemispherical. The first regulating piston 731 has a first positioning groove 733, and the part of the first sliding block 523 extending out of the first sliding groove 522 can be engaged with the first positioning groove 733.

[0079] The loading rack 520 moves towards the connecting pipe 400. When the loading rack 520 moves to a certain position, it comes into contact with the first regulating piston 731, thereby driving the first regulating piston 731 to move towards the bottom of the first regulating cylinder 732. The hydraulic oil in the first regulating cylinder 732 flows into the first liquid storage cylinder 740, increasing the liquid volume in the first liquid storage cylinder 740, and stretching the first return spring 742. When the loading rack 520 continues to move until it comes into contact with the first opening and closing valve 744, the first opening and closing valve 744... When the valve is opened, the first regulating piston 731 is engaged in the first groove 521, and the first sliding block 523 and the first positioning groove 733 are engaged under the action of the first sliding spring 524. After the first opening and closing valve 744 is opened, the hydraulic oil in the first liquid storage cylinder 740 gradually flows into the first moving hydraulic tank 710 under the action of the first reset spring 742 restoring deformation force. This causes the first moving hydraulic piston 720 to move towards the discharge port 430, which pushes the activated carbon block 410 on the feeding rack 520 down.

[0080] The loading rack 520 moves away from the connecting pipe 400, the first on / off valve 744 closes, and the loading rack 520 drives the first regulating piston 731 to move away from the bottom of the first regulating cylinder 732, so that the liquid in the first moving hydraulic tank 710 flows into the first regulating cylinder 732. When the loading rack 520 continues to move to a certain position, the first regulating piston 731 can no longer move, so that the first regulating piston 731 is disengaged from the loading rack 520. The loading rack 520 can be reset by continuing to move.

[0081] Referring to Figure 3, the second pusher 550 is connected to the inner wall of the receiving box 510, and the second pusher 550 can move along the length of the connecting pipe 400 to push the activated carbon block 410 on the unloading rack 530 down, that is, to push the activated carbon block 410 on the unloading rack 530 towards the upward feeding port 420. The receiving box 510 is provided with a second moving component 800 for driving the second pusher 550 to move.

[0082] The second moving assembly 800 includes a second moving hydraulic tank 810 and a second moving hydraulic piston 820. The second moving hydraulic tank 810 is fixedly connected to the side wall of the receiving box 510, the second moving hydraulic piston 820 is sealed and slidably connected to the second moving hydraulic tank 810 and passes through the receiving box 510, and the second pusher 550 is fixedly connected to the side of the second moving hydraulic piston 820 away from the second moving hydraulic tank 810.

[0083] A second control assembly 830 is provided on the housing 510 for driving the second movable hydraulic piston 820 to slide. The second control assembly 830 includes a second control cylinder 832 and a second control piston 831. The second control cylinder 832 is fixedly connected to the side of the housing 510 near the ground and communicates with the second movable hydraulic tank 810. Both the second movable hydraulic tank 810 and the second control cylinder 832 contain hydraulic oil. The second control piston 831 passes through the side wall of the housing 510 and is connected to the unloading rack 530. The second control piston 831 and the second control cylinder 832 are in a sealed sliding connection. When the unloading rack 530 moves towards the ground, the pressure in the second control cylinder 832 increases, causing the hydraulic oil in the second control cylinder 832 to flow into the second movable hydraulic tank 810, and the second movable hydraulic piston 820 slides towards the loading port 420.

[0084] Referring to Figures 3 and 6, in order to prevent the unloading rack 530 from interfering with the second pusher rack 550, a second liquid storage cylinder 840 is fixedly connected to the side of the accommodating box 510 away from the ground. A second liquid storage piston 841 is provided inside the second liquid storage cylinder 840. The second liquid storage piston 841 is slidably connected to the second liquid storage cylinder 840 in a sealed manner. A second return spring 842 is provided inside the second liquid storage cylinder 840. One end of the second return spring 842 is fixedly connected to the bottom of the second liquid storage cylinder 840, and the other end is fixedly connected to the second liquid storage piston 841. Under the elastic force of the second return spring 842, the second liquid storage piston 841 retracts into the second liquid storage cylinder 840.

[0085] The second liquid storage cylinder 840 is connected to the second movable hydraulic tank 810 via a second connecting pipe 811. A second on / off valve 844 is provided on the second connecting pipe 811. The second on / off valve 844 is fixedly connected to the inner wall of the accommodating box 510 near the ground and is located on the moving trajectory of the unloading rack 530, so that the second on / off valve 844 is opened when the unloading rack 530 moves down.

[0086] The second reservoir 840 and the second regulating reservoir 832 are connected by a second connecting pipe 843. A one-way valve is installed on the second connecting pipe 843 to allow the hydraulic oil in the second regulating reservoir 832 to flow unidirectionally into the second reservoir 840. The second movable hydraulic tank 810 and the second regulating reservoir 832 are connected by a second connecting pipe 812. A one-way valve is installed on the second connecting pipe 812 to allow the liquid in the second movable hydraulic tank 810 to flow unidirectionally into the second regulating reservoir 832.

[0087] Referring to Figures 3 and 7, to further prevent interference between the unloading rack 530 and the second pusher rack 550, the moving distance of the second regulating piston 831 is no greater than 1 / 2 of the moving distance of the unloading rack 530. Furthermore, the unloading rack 530 and the second regulating piston 831 are detachably connected. A connecting plate 535 is fixedly connected to the unloading rack 530. A second groove 531 is formed on the connecting plate 535. A second sliding groove 532 is formed on the side wall of the second groove 531. A second sliding block 533 and a second sliding spring 534 are arranged in the second sliding groove 532. One end of the second sliding spring 534 is fixedly connected to the bottom of the second sliding groove 532, and the other end is fixedly connected to the second sliding block 533. Under the elastic force of the second sliding spring 534, a portion of the second sliding block 533 extends out of the second sliding groove 532, and the portion of the second sliding block 533 extending out of the second sliding groove 532 is hemispherical. The second regulating piston 831 has a second positioning groove 833, and the part of the second sliding block 533 extending out of the second sliding groove 532 can be engaged with the second positioning groove 833.

[0088] The unloading rack 530 moves away from the connecting pipe 400. When the unloading rack 530 moves to a certain position, it comes into contact with the second regulating piston 831, thereby driving the second regulating piston 831 to move towards the bottom of the second regulating cylinder 832. The hydraulic oil in the second regulating cylinder 832 flows into the second reservoir 840, increasing the liquid volume in the second reservoir 840 and stretching the second return spring 842. When the unloading rack 530 continues to move until it comes into contact with the second opening and closing valve, the second opening and closing valve is opened. During this process, the second regulating piston 831 is engaged in the second groove 531, and the second sliding block 533 and the second positioning groove 833 are engaged under the action of the second sliding spring 534. After the second opening and closing valve is opened, the hydraulic oil in the second reservoir 840 gradually flows into the second moving hydraulic tank 810 under the action of the second reset spring 842 restoring deformation force, thereby causing the second moving hydraulic piston 820 to move towards the feed port 420, that is, pushing the activated carbon block 410 on the feed rack 530 down.

[0089] The unloading rack 530 moves towards the connecting pipe 400, the second on / off valve closes, and the unloading rack 530 drives the second regulating piston 831 to move away from the bottom of the second regulating cylinder 832, so that the liquid in the second moving hydraulic tank 810 flows into the second regulating cylinder 832. When the unloading rack 530 continues to move to a certain position, the second regulating piston 831 can no longer move, so that the second regulating piston 831 is disengaged from the unloading rack 530. The unloading rack 530 can be reset by continuing to move.

[0090] The implementation principle of this application embodiment is as follows: the suction fan 210 operates and draws the dust in the workshop 100 into the connecting pipe 400 through the suction pipe 220. After being filtered by the filter component, the dust enters the workshop 100 through the blower pipe 321 under the action of the blower 310. When the air detection sensor detects that the air quality in the blower pipe 320 has decreased, it controls the drive motor 631 to run through the electrical signal, so that the replacement component 500 can run to replace the expired activated carbon block 410.

[0091] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
