Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, specifically to a dust collection device for a paper product processing workshop. Background Technology

[0002] With the development of modern society, paper products, due to their lightweight, ease of processing, and low cost, have achieved comprehensive penetration in human life and production. From everyday items like toilet paper and notepads to newspapers and books that carry information, and to folders that are indispensable in office settings, paper products have become deeply integrated into every aspect of life.

[0003] In existing paper product manufacturing processes, the conventional procedure typically involves first classifying and storing fibrous raw materials such as wood and grass, followed by cutting and screening to ensure that the raw material specifications meet the technical requirements of the cooking or pulping processes, thus laying the foundation for subsequent papermaking and forming steps. However, in actual production, the raw material handling and processing inevitably generate a large amount of dust, which not only pollutes the workshop environment but also affects the health of operators.

[0004] A search revealed that patent CN220901355U discloses a dust collection device for paper product processing. While this device uses a suction fan to draw dust into a collection box, thus collecting it, it has several technical drawbacks. First, the dust suction position is relatively fixed, making it difficult to adapt to the varied processing positions on the production line, resulting in low dust collection efficiency. Second, after prolonged use, the filter screen is prone to clogging due to dust accumulation, significantly reducing its filtration effect. This not only increases equipment maintenance costs but also affects production continuity. Therefore, further improvements to the dust collection system are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust collection device for paper product processing workshops, solving the problems mentioned in the background art.

[0006] The solution of this utility model to the above-mentioned technical problems is as follows:

[0007] A dust collection device for a paper product processing workshop includes a trolley, on which a mounting frame and a dust filter box are fixedly installed, and a dust suction hood is installed on the dust filter box through an air inlet pipe.

[0008] A hydraulic rod is installed inside the mounting bracket, and a guide block is installed on the air intake pipe;

[0009] The inner wall of the dust filter box is equipped with a filter screen and a filter bag, and the bottom surface of the filter screen is equipped with a silicone protrusion by a fixing bracket.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the guide block is slidably sleeved on the mounting bracket, and the bottom end face of the guide block is mounted on the output shaft of the hydraulic rod.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] The height of the dust hood can be flexibly adjusted by sliding the guide block on the mounting frame via a hydraulic rod. In paper processing workshops, different processing equipment has different heights. For example, the dust generation positions of large cutting machines and small printing machines are different. This structure allows the dust hood to adapt to various equipment, ensuring that it is in the optimal dust collection position, effectively improving dust collection efficiency and avoiding dust leakage caused by improper dust hood positioning.

[0014] Furthermore, a push rod is fixedly installed on the trolley, and casters are installed on the bottom surface of the trolley.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The push rod design allows operators to easily push the cart, enabling the device to move freely within the workshop; and the casters allow it to reach dust-generating points, achieving flexible mobile dust collection, significantly improving the device's applicability and ease of use.

[0017] Furthermore, an air pump is installed at the end of the dust filter box away from the air inlet pipe, and the air pump is equipped with a first discharge pipe and a second discharge pipe.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] The air pump, as a power source, can generate suction to draw gas from the dust filter box, allowing the dust filter box to quickly suck dust from the workshop into the dust filter box through the combination of the air inlet pipe and the dust suction hood.

[0020] Furthermore, the end of the first discharge pipe facing away from the air pump is installed inside the dust filter box, and the dust filter box is connected to the air pump gas through the first discharge pipe.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] This structure ensures a stable gas flow channel between the air pump and the dust filter box, allowing the suction force generated by the air pump to be evenly distributed inside the dust filter box. Under the influence of suction, dust-laden air passes orderly through the filter screen and filter bag for filtration, ensuring the stability of the filtration process.

[0023] Furthermore, a rack is mounted on the guide block via an L-shaped connecting bracket. The rack is used to drive the silicone bumps to vibrate and clean the filter screen.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] When the hydraulic rod drives the guide block to move up and down, the rack reciprocates accordingly, causing the silicone bumps to vibrate through mechanical transmission. During paper product processing, fine paper scraps and dust easily adhere to the filter mesh, clogging it and reducing filtration efficiency. The vibration of the silicone bumps effectively shakes off the dust adhering to the filter, cleaning it without the need for manual disassembly and maintenance, reducing equipment downtime and improving production efficiency.

[0026] This utility model provides a dust collection device for a paper product processing workshop. It has the following beneficial effects:

[0027] The height of the dust hood can be flexibly adjusted by sliding the guide block on the mounting frame via a hydraulic rod. This design allows the device to adapt to processing equipment of different heights, such as large cutting machines and small printing machines, ensuring that the dust hood is always in the optimal dust collection position, effectively improving dust collection efficiency and preventing dust leakage.

[0028] The omnidirectional wheels and push rod design mounted on the bottom of the trolley allow the device to move freely within the workshop and precisely locate the dust generation point. This mobile dust collection method significantly improves the applicability and ease of use of the device, making it particularly suitable for paper product processing workshops with multiple equipment and workstations.

[0029] The dust collection box contains a two-stage filtration system consisting of a screen and filter bags, effectively intercepting dust particles of varying sizes. The screen filters out larger particles like paper scraps and dust, while the filter bags further capture finer dust particles, ensuring that emissions meet environmental standards and protecting the air quality within the workshop.

[0030] When the hydraulic rod drives the guide block to move up and down, the rack moves accordingly, causing the silicone protrusions to vibrate, thus automatically cleaning the filter screen. This design avoids manual disassembly and maintenance, reduces equipment downtime, ensures the continuous and efficient operation of the filtration system, and extends the service life of the filter screen.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0042] Example 1

[0043] A dust collection device for a paper product processing workshop includes a trolley 1, on which a mounting frame 2 and a dust filter box 4 are fixedly installed. A dust suction hood 3 is installed on the dust filter box 4 through an air inlet pipe 301.

[0044] A hydraulic rod 201 is installed inside the mounting bracket 2, and a guide block 202 is installed on the air inlet pipe 301;

[0045] The inner wall of the dust filter box 4 is equipped with a filter screen 402 and a filter bag 403. The bottom surface of the filter screen 402 is equipped with a silicone protrusion 401 through a fixing bracket 404.

[0046] The guide block 202 is slidably sleeved on the mounting frame 2. The bottom end of the guide block 202 is mounted on the output shaft of the hydraulic rod 201. The guide block 202 is driven to slide on the mounting frame 2 by the hydraulic rod 201, which allows for flexible adjustment of the height of the dust collection hood 3. In paper product processing workshops, the heights of different processing equipment vary. For example, the dust generation positions of large cutting machines and small printing machines are different. This structure allows the dust collection hood 3 to adapt to various types of equipment, ensuring that it is in the optimal dust collection position, effectively improving dust collection efficiency, and avoiding dust leakage due to improper positioning of the dust collection hood 3.

[0047] A push rod is fixedly installed on the trolley 1, and casters are installed on the bottom surface of the trolley 1. The push rod makes it easy for the operator to push the trolley 1, so that the device can move freely in the workshop; and the casters can reach the dust generation point, realizing flexible mobile dust collection, which significantly improves the applicability and ease of use of the device.

[0048] An air pump 5 is installed at the end of the dust filter box 4 away from the air inlet pipe 301. The air pump 5 is equipped with a first discharge pipe 501 and a second discharge pipe 502. The air pump 5 serves as a power source and can generate suction to extract the gas in the dust filter box 4, so that the dust filter box 4 can quickly suck the dust in the workshop into the dust filter box 4 through the combination of the air inlet pipe 301 and the dust suction hood 3.

[0049] The first discharge pipe 501, located away from the air pump 5, is installed inside the dust filter box 4. The dust filter box 4 is connected to the air pump 5 via the first discharge pipe 501. This structure ensures a stable gas flow channel between the air pump 5 and the dust filter box 4, allowing the suction force generated by the air pump 5 to act evenly inside the dust filter box 4. Under the action of suction, the dust-laden air passes orderly through the filter screen 402 and filter bag 403 for filtration, ensuring the stability of the filtration process.

[0050] Example 2

[0051] To vibrate and clean the mesh during dust collection, for example, such as Figures 1 to 5 As shown, this utility model also includes:

[0052] A rack 204 is mounted on the guide block 202 via an L-shaped connecting bracket 203. The rack 204 drives the silicone bump 401 to vibrate and clean the filter screen 402. When the hydraulic rod 201 drives the guide block 202 to move up and down, the rack 204 reciprocates accordingly, causing the silicone bump 401 to vibrate through mechanical transmission. During paper product processing, fine paper scraps and dust easily adhere to the mesh of the filter screen 402, clogging it and reducing the filtration effect. The vibration of the silicone bump 401 effectively shakes off the dust adhering to the filter screen 402, achieving cleaning of the filter screen 402 without manual disassembly and maintenance, reducing equipment downtime and improving production efficiency.

[0053] Working principle:

[0054] The operator pushes the device with a push rod on the trolley 1, and uses the casters on the bottom end to make the device move freely in the workshop and accurately reach the dust generation point (such as next to large cutting machines, small printing machines, etc.).

[0055] The hydraulic rod 201 inside the mounting frame 2 drives the guide block 202 to slide on the mounting frame 2 (the guide block 202 is slidably sleeved on the mounting frame 2, and its bottom end is connected to the output shaft of the hydraulic rod 201), thereby driving the air inlet pipe 301 and the dust hood 3 to move up and down to adapt to the dust generation position of equipment of different heights and ensure that the dust hood 3 is at the optimal dust collection height.

[0056] Power drive: After the air pump 5 is started, it forms a negative pressure suction in the dust filter box 4 through the first discharge pipe 501.

[0057] Dust collection: Dust-laden air is drawn into the dust filter box 4 through the dust suction hood 3 and the air inlet pipe 301.

[0058] Primary filtration: Larger particles of paper scraps and dust are intercepted by filter 402.

[0059] Secondary filtration: After fine dust passes through filter screen 402, it is further captured by filter bag 403. The purified gas is discharged through the second discharge pipe 502 of air pump 5 to ensure that the emission meets environmental protection standards.

[0060] When the hydraulic rod 201 drives the guide block 202 to move up and down, the guide block 202 drives the rack 204 to reciprocate through the L-shaped connecting frame 203.

[0061] The rack 204 vibrates the silicone protrusions 401 on the fixed frame 404 through mechanical transmission, shaking off the dust adhering to the mesh of the filter screen 402, preventing the filter screen 402 from clogging, eliminating the need for manual disassembly and maintenance, and ensuring the continuous and efficient operation of the filtration system.
