Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to a dust removal device for activated carbon production workshops. Background Technology

[0002] During the production and processing of activated carbon, a large amount of carbon powder and dust impurities are generated. Dust removal equipment has become a core supporting facility for the production of activated carbon. High-efficiency activated carbon blocks are the core components of the dust removal equipment to achieve dust adsorption and purification. After long-term adsorption of dust, they need to be disassembled and replaced regularly to ensure the purification effect of the dust removal equipment.

[0003] However, when existing dust removal equipment disassembles and replaces activated carbon blocks, the slight vibrations generated during the manual operation cause the floating dust accumulated on the surface of the activated carbon blocks and the dust adhering to the pores to detach from the activated carbon blocks. Under the action of airflow, this dust escapes directly into the workshop air through the equipment's channels and cavity openings, causing secondary pollution to the workshop environment. This not only increases the workload of dust cleaning in the workshop but also causes workers to inhale the escaped dust, endangering their health. At the same time, the escaped dust also adheres to the surface of the workshop's production equipment, affecting the normal operation and service life of the production equipment. Summary of the Invention

[0004] In order to solve the problems in the background art, the present invention proposes a dust removal device for activated carbon production workshops.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for an activated carbon production workshop includes a housing and further includes: The outer casing is fixedly attached to the inside of the housing; The inner shell is located inside the outer shell. One end of the inner shell has an air inlet and the other end has an air outlet. The inner side of both the air inlet and the air outlet has a slot 1. A sealing plate is slidably installed in the slot 1. The inner shell has a slot 2 near the air inlet. A filter screen plate is slidably installed in the slot 2. Multiple return springs are provided between the filter screen plate and the outer shell. An electric actuator is mounted on the outer wall of the inner shell via a mounting base. The movable end of the electric actuator is provided with a driving mechanism that first acts on the sealing plate and then on the filter screen plate. A high-efficiency activated carbon block is provided, wherein the high-efficiency activated carbon block is disposed in an inner shell, and a support mechanism for supporting the high-efficiency activated carbon block is provided at one end of the inner shell near the air inlet, and a compression mechanism for compressing the high-efficiency activated carbon block is provided at one end of the inner shell near the air outlet.

[0006] Preferably, the drive mechanism includes a connecting plate fixed to the top of the electric push rod, a rectangular box fixed to the connecting plate, and a connecting rod fixed to the rectangular box, wherein the filter screen plate has a notch that mates with the connecting rod; A movable block is slidably disposed inside the rectangular box. A U-shaped rod is fixedly connected to the movable block. The end of the U-shaped rod away from the movable block is fixedly connected to a sealing plate. A compression spring is disposed between the movable block and the inner wall of the rectangular box.

[0007] Preferably, the filter screen is provided with multiple scrapers evenly arranged on the side facing the high-efficiency activated carbon block.

[0008] Preferably, the sealing plate has a rectangular opening that matches the air inlet and air outlet. The rectangular opening can be connected to or misaligned with the air inlet and air outlet as the sealing plate slides.

[0009] Preferably, a fixing groove that mates with a sealing plate is provided on the inner bottom surface of the housing, and the bottom of the sealing plate moves through the bottom of the outer shell and extends into the fixing groove.

[0010] Preferably, the support mechanism includes mounting plates symmetrically fixed to the inner wall of the inner shell and near the air inlet. Each mounting plate is symmetrically fixed with a sleeve. A movable rod is slidably provided inside the sleeve. A contact plate is fixed to the outer end of the movable rod. The contact plate contacts the end face of the high-efficiency activated carbon block. A compression spring is provided between the inner wall of the sleeve and the outer wall of the movable rod.

[0011] Preferably, the extrusion mechanism includes an I-beam tube fixed to the inner wall of the inner shell and near the air outlet. A plurality of circular tubes are evenly arranged on the side of the I-beam tube facing the high-efficiency activated carbon block, and the circular tubes are connected to the interior of the I-beam tube. A sealing column is slidably arranged inside the circular tube. A circular plate is fixed to the end of the sealing column away from the I-beam tube, and the circular plate is in contact with the end face of the high-efficiency activated carbon block. The top of the I-beam tube is provided with an air guide tube, and the end of the air guide tube away from the I-beam tube is movably inserted into the inner shell near the filter screen.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention utilizes a drive mechanism to achieve a sequential action of the sealing plate and the filter plate, replacing manual operation of opening and closing the air inlet and outlet, and vibrating the filter plate, thus significantly improving the automation level of the equipment. The filter plate facilitates the filtration of large-diameter impurities in the air. Under the action of the filter plate and the return spring, the filter plate moves up and down reciprocatingly, vibrating to prevent impurities from clogging the mesh, thereby facilitating the filtration of dusty air and improving filtration efficiency. This invention utilizes the coordinated use of a support mechanism, an extrusion mechanism, and a scraper. When dust accumulates on the surface of the high-efficiency activated carbon block, causing blockage, the pressure at the air inlet of the inner shell increases. Air flows through the air duct, driving the extrusion mechanism to push the activated carbon block into contact with the scraper. Combined with the up-and-down movement of the filter screen, the scraper can thoroughly remove the accumulated dust and floating dust from the surface of the activated carbon block, eliminating the need for manual disassembly and cleaning. After the dust removal is completed, the pressure returns to normal, and the support mechanism causes the activated carbon block to separate from the scraper, ensuring normal adsorption operation and continuously maintaining the dust removal and purification capacity of the equipment. This invention achieves a complete seal of the inner shell cavity during the disassembly and replacement of high-efficiency activated carbon blocks by using a rectangular opening on the sealing plate that is matched with the air inlet and outlet in a staggered manner. This keeps the activated carbon blocks in a sealed environment and prevents dust from escaping. At the same time, the outer shell and the inner shell form a double-layered nested protective structure, and the gap between the two layers constitutes a secondary dust barrier. Even if there is slight dust leakage in the inner shell, the outer shell can effectively block it, solving the problem of large-scale dust pollution of the surrounding environment during the replacement and disassembly of activated carbon blocks, and helping to protect the environment around the disassembly site.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1 - Figure 10 The present invention provides a technical solution: A dust removal device for an activated carbon production workshop includes a housing 1, wherein the air inlet of the housing 1 is connected to the air outlet of an exhaust fan (existing technology, not shown in the figure), facilitating the extraction of air from the activated carbon production workshop into the housing 1, and further includes: The outer shell 2 is fixed inside the housing 1; a double-layered nested protective structure is formed between the outer shell 2 and the inner shell 6. One end of the outer shell 2 is fixed to the inner wall of the housing 1, and at the same time provides a fixed fulcrum for the return spring 8. The double-layered gap structure can form a secondary dust barrier. Even if the inner shell 6 has a slight dust leakage, the outer shell 2 can effectively block the dust and further reduce the possibility of dust overflow.

[0017] The inner shell 6 is located inside the outer shell 2. The inner shell 6 is the core dust removal cavity of the equipment. It has an air inlet 32 ​​at one end and an air outlet 33 at the other, providing a directional flow channel for dust-laden airflow in the workshop. Slots 1-29 are provided on the inner sides of both the air inlet 32 ​​and the air outlet 33, providing precise sliding guidance for the sealing plate 9 and ensuring smooth, unobstructed sliding. The sealing plate 9 slides within slot 1-29. The sealing plate 9 can be used to seal the air inlet 32 ​​and the air outlet 33 when the high-efficiency activated carbon block 7 is disassembled, preventing dust from escaping into the surrounding air during disassembly and replacement, thus protecting the surrounding environment. A slot 2-30 is provided on the inner shell 6 near the air inlet 32, providing a space for the filter screen 4. The filter screen 4 is slidably mounted in slot 2 30. During the extension and retraction process, the movable end of the electric push rod 14 in the drive mechanism moves rapidly, causing the connecting rod 11 and the notch 18 to separate quickly. Then, under the action of the return spring 8, the filter screen 4 vibrates, preventing impurities from clogging the mesh of the filter screen 4, thus facilitating the filtration of dusty air and improving filtration efficiency. Multiple return springs 8 are provided between the filter screen 4 and the outer casing 2. After the dust scraping action is completed, the return springs 8 automatically return the filter screen 4 to its initial position, preparing it for the next dust removal operation without manual reset, improving the ease of operation. Simultaneously, they also vibrate the filter screen 4, preventing impurities from clogging the mesh of the filter screen 4 and facilitating air filtration.

[0018] The electric actuator 14 is mounted on the outer wall of the inner shell 6 via the mounting base 10, providing a stable linear power output for the drive mechanism, and its stroke can be precisely controlled. The movable end of the electric actuator 14 is equipped with a drive mechanism that acts first on the sealing plate 9 and then on the filter screen plate 4. Through the use of the drive mechanism, the sequential action sequence of the sealing plate 9 and the filter screen plate 4 is realized, providing a power basis for the step-by-step operation of sealing the air inlet 32 ​​and the air outlet 33 and vibrating the filter screen plate 4, replacing manual operation and improving the automation level of the equipment.

[0019] The high-efficiency activated carbon block 7 is set in the core cavity of the inner shell 6. Its surface and pores can fully adsorb impurities such as dust, tar, flocculent matter, and carbon powder in the dust-laden airflow, thereby achieving deep purification of the dust-laden gas in the activated carbon production workshop and reducing the dust concentration in the workshop from the source. The inner shell 6 is provided with a support mechanism for supporting the high-efficiency activated carbon block 7 at one end near the air inlet 32. The use of the support mechanism facilitates the compression of the high-efficiency activated carbon block 7, preventing the high-efficiency activated carbon block 7 from contacting the scraper 19. When the high-efficiency activated carbon block 7 is working normally, the scraper 19 will not contact the high-efficiency activated carbon block 7, thus facilitating the protection of the high-efficiency activated carbon block 7. An extrusion mechanism for extruding the high-efficiency activated carbon block 7 is provided at one end of the inner shell 6 near the air outlet 33. When the surface of the high-efficiency activated carbon block 7 is blocked by dust, air cannot pass through the high-efficiency activated carbon block 7, thereby increasing the pressure at the end of the inner shell 6 near the air inlet 32. Then, the air enters the extrusion mechanism through the air guide pipe 3, causing the extrusion mechanism to work. As the pressure increases, the pushing force of the extrusion mechanism on the high-efficiency activated carbon block 7 overcomes the resistance of the support mechanism, thereby causing the high-efficiency activated carbon block 7 to move and further contact the high-efficiency activated carbon block 7 with the scraper 19. Then, the dust on the high-efficiency activated carbon block 7 is cleaned by the up and down movement of the scraper 19.

[0020] In this invention, the driving mechanism includes a connecting plate 31 fixed to the top of the electric push rod 14, a rectangular box 12 fixed to the connecting plate 31, and a connecting rod 11 fixed to the rectangular box 12. The filter screen plate 4 has a notch 18 that cooperates with the connecting rod 11. When the connecting rod 11 moves downward, it will be engaged in the notch 18. Then, as the movable end of the electric push rod 14 continues to retract, it will drive the filter screen plate 4 to move downward, thereby realizing the movement of the filter screen plate 4. A movable block 16 is slidably disposed inside the rectangular box 12. A U-shaped rod 13 is fixedly connected to the movable block 16. The end of the U-shaped rod 13 away from the movable block 16 is fixedly connected to the sealing plate 9. A compression spring 17 is provided between the movable block 16 and the inner wall of the rectangular box 12. By using the compression spring 17, the movable block 16 can be compressed, so that the sealing plate 9 and the rectangular box 12 move synchronously. This mechanism can convert the single power of the electric push rod 14 into a step-by-step drive for the sealing plate 9 and the filter screen plate 4. By utilizing the elastic buffering characteristics of the compression spring 17, the electric push rod 14 first drives the sealing plate 9 to complete the sealing action, and then drives the filter screen plate 4 to move the filter screen plate 4, ensuring that the two actions do not conflict and the timing is precise. The cooperation between the connecting rod 11 and the notch 18 can provide additional guidance for the sliding of the filter screen plate 4 and improve the stability of the sliding of the filter screen plate 4.

[0021] In this invention, multiple scrapers 19 are evenly arranged on the side of the filter screen plate 4 facing the high-efficiency activated carbon block 7. The scrapers 19 can make close contact with the surface of the high-efficiency activated carbon block 7 during the sliding process of the filter screen plate 4, and thoroughly scrape off the accumulated dust and floating dust adsorbed on its surface, so as to avoid the accumulation of dust affecting the adsorption effect of the high-efficiency activated carbon block 7. At the same time, scraping off the accumulated dust in advance can prevent dust from being raised when replacing it.

[0022] In this invention, the sealing plate 9 has a rectangular opening 15 that cooperates with the air inlet 32 ​​and the air outlet 33. The rectangular opening 15 can be connected to or misaligned with the air inlet 32 ​​and the air outlet 33 as the sealing plate 9 slides. The rectangular opening 15 can be connected to or misaligned with the air inlet 32 ​​and the air outlet 33 as the sealing plate 9 slides, so as to realize the airflow during dust removal operation and the full sealing of the cavity when the activated carbon block is replaced, preventing dust from overflowing.

[0023] In this invention, a fixing groove 5 is provided on the inner bottom surface of the box 1 to cooperate with the sealing plate 9. The bottom of the sealing plate 9 moves through the bottom of the outer shell 2 and extends into the fixing groove 5. When the sealing plate 9 is unfolded, it is inserted into the fixing groove 5 to fix the outer shell 2 and the inner shell 6, which makes it easier for the outer shell 2 and the inner shell 6 to be stably fixed in the box 1, which is beneficial for dust treatment.

[0024] In this invention, the support mechanism includes mounting plates 20 symmetrically fixed to the inner wall of the inner shell 6 and near the air inlet 32. Each mounting plate 20 is symmetrically fixed with a sleeve 21. A movable rod 22 is slidably provided inside the sleeve 21. A contact plate 23 is fixed to the outer end of the movable rod 22. The contact plate 23 contacts the end face of the high-efficiency activated carbon block 7. A compression spring 28 is provided between the inner wall of the sleeve 21 and the outer wall of the movable rod 22. The elastic characteristics of the compression spring 28 can achieve flexible support for the high-efficiency activated carbon block 7, which can adapt to high-efficiency activated carbon blocks 7 of different specifications and thicknesses, thereby improving the adaptability of the equipment.

[0025] In this invention, the extrusion mechanism includes an I-beam tube 25 fixed to the inner wall of the inner shell 6 and near the air outlet 33. A plurality of circular tubes 27 are uniformly arranged on the side of the I-beam tube 25 facing the high-efficiency activated carbon block 7, and the circular tubes 27 are connected to the interior of the I-beam tube 25. A sealing column 26 is slidably arranged inside the circular tube 27. A circular plate 24 is fixed to the end of the sealing column 26 away from the I-beam tube 25, and the circular plate 24 is in contact with the end face of the high-efficiency activated carbon block 7. The top of the I-beam tube 25 is provided with an air guide pipe 3. The end of the air guide pipe 3 away from the I-beam tube 25 moves through the inner shell 6 near the filter screen plate 4. When the high-efficiency activated carbon block 7 is blocked by dust, the pressure in the inner shell 6 near the air inlet 32 ​​will increase. Then, air enters the I-beam tube 25 and the circular tube 27 through the air guide pipe 3. As the pressure increases, it will push the sealing column 26 to move, thereby driving the high-efficiency activated carbon block 7 to move. When the dust on the high-efficiency activated carbon block 7 is scraped off, air can pass through the high-efficiency activated carbon block 7. At this time, the pressure decreases, and then the high-efficiency activated carbon block 7 is reset by the action of the extrusion support mechanism.

[0026] Working principle: When using this invention, the electric actuator 14 is first opened, and the retraction of the movable end of the electric actuator 14 is divided into two stages: First stage: As the electric actuator 14 retracts, it moves the rectangular box 12 downward. Under the action of the compression spring 17, the movable block 16 moves synchronously with the rectangular box 12, thereby moving the connecting rod 11 and the U-shaped rod 13 downward, which in turn drives the sealing plate 9 downward. As the sealing plate 9 moves downward and inserts into the fixing groove 5 on the bottom surface of the box 1, the outer shell 2 and the inner shell 6 are fixed. At the same time, the rectangular opening 15 on the sealing plate 9 coincides with the air inlet 32 ​​and the air outlet 33 respectively, so that the inner shell 6 is opened, which facilitates the passage of air through the inner shell 6. When the sealing plate 9 is inserted into the fixing groove 5, the connecting rod 11 is engaged in the notch 18 on the filter screen plate 4. At this time, the movable end of the electric push rod 14 retracts into the second stage; and the sealing plate 9 will no longer move downward. Second stage: As the movable end of the electric push rod 14 continues to retract, the filter screen plate 4 will move downward. When the movable end of the electric push rod 14 has fully retracted, the movable end of the electric push rod 14 will extend to reach the initial end of the second stage. Then, under the action of the return spring 8, the filter screen plate 4 will be reset. The movable end of the electric push rod 14 will move repeatedly in the second stage, thereby realizing the up-and-down reciprocating movement of the filter screen plate 4 and realizing the vibration of the filter screen plate 4. This will prevent impurities from clogging the mesh of the filter screen plate 4 and will help filter the air. As the air is purified, dust will adhere to the surface of the high-efficiency activated carbon block 7. When too much dust adheres to the high-efficiency activated carbon block 7, air will not be able to pass through the high-efficiency activated carbon block 7. As the air accumulates in the air inlet 32 ​​of the outer shell 2, the pressure at the air inlet 32 ​​inside the outer shell 2 will increase. Then, air enters the I-beam tube 25 through the air guide tube 3, and pushes the sealing column 26 to move, which in turn pushes the high-efficiency activated carbon block 7. When the thrust of the sealing column 26 on the high-efficiency activated carbon block 7 is greater than the thrust of the support mechanism on the high-efficiency activated carbon block 7, the high-efficiency activated carbon block 7 will move. Finally, the high-efficiency activated carbon block 7 will come into contact with the scraper 19 on the filter screen plate 4. As the filter plate 4 moves up and down, the scraper 19 moves up and down on the surface of the high-efficiency activated carbon block 7, thereby cleaning the dust attached to the high-efficiency activated carbon block 7. After the dust on the high-efficiency activated carbon block 7 is cleaned, air passes through the high-efficiency activated carbon block 7, and the pressure at the air inlet 32 ​​decreases. Under the action of the support mechanism, the high-efficiency activated carbon block 7 is separated from the scraper 19. When it is necessary to disassemble the high-efficiency activated carbon block 7, the movable end of the electric push rod 14 is extended to first reset the filter screen plate 4, and then reset the sealing plate 9, thereby sealing the air inlet 32 ​​and the air outlet 33. This ensures that the high-efficiency activated carbon block 7 is always in a sealed environment during disassembly, preventing dust from escaping into the surrounding air, which is beneficial to the protection of the surrounding environment. Finally, remove the outer shell 2 and inner shell 6 from the box 1, replace the high-efficiency activated carbon block 7 inside the inner shell 6, and finally reinstall the outer shell 2 and inner shell 6 inside the box 1.
