Description

Technical Field

[0001] This utility model belongs to the field of boiler slag removal technology, and in particular relates to an air purification device for boiler slag removal. Background Technology

[0002] Boiler ash removal refers to the process of removing ash, slag, and unburned coal residues produced during boiler operation. Excessive accumulation of these residues can affect boiler thermal efficiency, increase energy consumption, and even threaten the safe operation of the boiler. Air purification devices for boiler ash removal are environmentally friendly equipment specifically designed to treat exhaust gases and residues generated after boiler combustion. Through a series of filtration and purification processes, such as electrostatic precipitators, bag filters, and activated carbon adsorption, they effectively remove harmful substances such as particulate matter, sulfides, and nitrogen oxides from the exhaust gases, reducing environmental pollution.

[0003] The problems with existing technologies are that existing equipment usually lacks an effective mechanism for quick disassembly of the pre-filter box, which makes maintenance inconvenient and time-consuming. At the same time, the lack of automatic cleaning function can easily cause particulate matter to accumulate, affecting equipment performance and service life. Utility Model Content

[0024] By adopting the above solution, the pre-filter box 6 can be stably installed in the connecting groove 5 by setting the fixing block 10 and the spring 9, and it is easy to disassemble and maintain quickly, thereby effectively improving the maintainability and ease of operation of the equipment.

[0025] refer to Figure 4 The front side of the receiving block 7 is provided with a through groove 11. The front side of the fixing block 10 is fixedly connected with a slider 12. The slider 12 is slidably connected to the inside of the through groove 11. The left and right sides of the front surface of the receiving block 7 are provided with sliding grooves 13. The front side of the receiving block 7 is provided with a guide plate 14. The left and right sides of the rear surface of the guide plate 14 are slidably connected to the inside of the sliding groove 13. The rear side of the guide plate 14 is provided with a guide groove 15. The guide groove 15 is at a certain angle. The slider 12 is slidably connected to the inside of the guide groove 15.

[0026] By adopting the above solution, the pre-filter box 6 can be stably installed in the connecting groove 5 by setting the fixing block 10 and the spring 9, and it is easy to disassemble and maintain quickly, thereby effectively improving the maintainability and ease of operation of the equipment.

[0027] refer to Figure 4The top of the guide plate 14 is fixedly connected to the connecting block 16, and the front side of the exhaust pipe 3 is provided with a pressing rod 17. The left and right sides of the bottom of the pressing rod 17 are fixedly connected to the top of the connecting block 16.

[0028] By adopting the above solution, the pressing rod 17 can be set to enable the synchronous downward movement of the guide plates 14 on both sides, which simplifies the disassembly process of the pre-filter box 6 and significantly improves the convenience of equipment maintenance.

[0029] refer to Figure 3 A connecting frame 18 is fixedly connected to the top of the exhaust pipe 3. A compression spring 19 is fixedly connected to the bottom of the connecting frame 18. An impact rod 20 is fixedly connected to the bottom of the compression spring 19. The top of the impact rod 20 passes through and extends out of the top of the connecting frame 18. A rack 21 is fixedly connected to the top of the impact rod 20. A motor 22 is fixedly connected to the top of the connecting frame 18. A half gear 23 is fixedly connected to the output end of the motor 22. The left side of the half gear 23 is rotatably connected to the top of the connecting frame 18. The half gear 23 and the rack 21 cooperate with each other.

[0030] By adopting the above solution, by setting half gear 23 and rack 21, particulate matter on the surface of pre-filter box 6 can be effectively shaken off, maintaining the efficient operation of the equipment and reducing the frequency of maintenance.

[0031] refer to Figure 3 A stabilizing plate 24 is fixedly connected to the top of the connecting frame 18. A stabilizing groove 25 is provided on the side of the stabilizing plate 24 near the rack 21. The front side of the rack 21 is slidably connected to the inside of the stabilizing groove 25.

[0033] refer to Figure 2 The bottom of the exhaust pipe 3 is provided with a slag discharge port 26, the position of which corresponds to the position of the pre-filter box 6. The left and right sides of the bottom of the slag discharge port 26 are provided with mounting grooves 27, and the bottom of the slag discharge port 26 is provided with a dust collection hopper 28. The left and right sides of the top of the dust collection hopper 28 are slidably connected to the inside of the mounting groove 27.

[0034] By adopting the above solution, the ash collection hopper 28 and slag discharge port 26 can effectively collect and discharge particulate matter, keep the pre-filter box 6 clean, and prevent particulate matter from re-entering the system.

[0035] The working principle of this utility model:

[0036] In use, first connect the inlet pipe 2 to the exhaust outlet. The exhaust gas will first pass through the pre-filter box 6 for preliminary filtration, then enter the purifier body 1 for purification, and finally be discharged from the exhaust pipe 3. During use, larger particles in the exhaust gas will be blocked by the pre-filter box 6 to prevent them from entering the purifier body 1. However, some larger particles may stick to the surface of the pre-filter box 6. At this time, the motor 22 can be started. The motor 22 drives the half gear 23 to rotate. The half gear 23 drives the rack 21 to move upward along the stabilizing groove 25. When the rack 21 moves to a certain position, it will disengage from the half gear 23. Then, the compression spring 19 will quickly reset the rack 21 and the impact rod 20. After the half gear 23 rotates one revolution, it will re-engage with the rack 21. This cycle continues, causing the impact rod 20 to repeatedly impact the exhaust gas. The top of pipe 3 effectively generates vibration, which shakes down the particles adhering to the surface of the pre-filter box 6. Then the particles will fall from the slag discharge port 26 into the ash collection hopper 28. After the equipment has been used for a certain period of time, the pre-filter box 6 needs to be cleaned. When disassembling the filter box, first press down the pressing rod 17. The pressing rod 17 drives the guide plates 14 on both sides to move downward. When the guide plates 14 move downward, since the slider 12 is slidably connected to the inside of the through groove 11, the slider 12 can only move left and right along the through groove 11. When the guide plates 14 move downward, the slider 12 will move towards the side closer to the spring 9 along the through groove 11 due to the tilt angle of the guide plates 14. Then the slider 12 drives the fixed block 10 to move. After the fixed blocks 10 on both sides are removed from the front side of the connecting groove 5, the pre-filter box 6 can be disassembled.

[0037] In summary, this boiler slag removal air purification device, through the coordinated use of the following components—purifier body 1, air inlet pipe 2, exhaust pipe 3, support frame 4, connecting groove 5, pre-filter box 6, receiving block 7, receiving groove 8, spring 9, fixing block 10, through groove 11, slider 12, sliding groove 13, guide plate 14, guide groove 15, connecting block 16, pressing rod 17, connecting frame 18, compression spring 19, impact rod 20, rack 21, motor 22, half gear 23, stabilizing plate 24, stabilizing groove 25, slag discharge port 26, installation groove 27, and ash collection hopper 28—solves the problems of existing equipment typically lacking an effective quick disassembly mechanism for the pre-filter box, resulting in inconvenient and time-consuming maintenance, and lacking an automatic cleaning function, which easily leads to particulate matter accumulation, affecting equipment performance and service life.
