[0016] 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.
[0017] Please see Figure 1-3This utility model provides a technical solution: a multi-stage dust removal and purification device for the production of high-strength wear-resistant castables, including a dust collector body 1, a top cover 2 detachably installed on the top of the dust collector body 1, a dust inlet on one side of the bottom of the dust collector body 1, and a dust inlet in the middle of the top of the top cover 2. A multi-stage filter cylinder 3 is embedded inside the dust collector body 1. Several independently adjustable support rings 4 are provided inside the multi-stage filter cylinder 3. The top of each support ring 4 is fitted with a filter medium 5 located inside the multi-stage filter cylinder 3. The three filter media 5, from top to bottom, are respectively a fine particle purification layer, a medium particle capture layer, and a coarse particle interception layer. A vertically distributed air outlet pipe 6 is provided in the middle of the interior of the dust collector body 1. The filter medium 5 has a circular plate structure and... The dust collector body 1 is fitted onto the outside of the outlet duct 6. The bottom end of the outlet duct 6 has an exhaust duct 7 that extends through to the outside of the dust collector body 1. The exhaust duct 7 can be connected to an external fan. The outlet duct 6 is equipped with several sets of multi-position blowers 8, each with a forked outlet. When the dust collector body 1 is in use, dust is introduced into it from the dust inlet and rises into the multi-stage filter cartridge 3. During this process, the three filter media 5—the fine particle purification layer, the medium particle capture layer, and the coarse particle interception layer—effectively intercept particulate impurities and dust. Simultaneously, the outlet duct 6, in conjunction with the exhaust duct 7, causes the multiple multi-position blowers 8 to periodically spray compressed air into the filter media 5. The multi-position blowers 8 ensure… Compressed air can evenly disperse and penetrate the circular plate structure of the filter media 5, causing the dust adhering to it to be forcefully blown away. This avoids excessive accumulation of dust on the surface of the filter media 5, reduces airflow resistance, and the independently adjustable height of the support ring 4 allows the spacing between each layer of filter media 5 to be adjusted according to actual operating conditions, optimizing the effective separation of dust of different particle sizes. This not only significantly improves the separation efficiency of dust of different particle sizes and reduces airflow resistance and energy consumption caused by dust accumulation, but also reduces maintenance frequency and cost, providing more stable and efficient dust treatment performance. The outer walls on both sides of the top of the multi-stage filter cartridge 3 are welded and fixed with snap-fit blocks 9, and the inner walls on both sides of the top of the dust collector body 1 are welded and fixed with a structure consistent with the snap-fit blocks 9. The receiving block 10 is fitted with a locking block 9, and handles are welded and fixed to both outer walls of the top two sides of the multi-stage filter cartridge 3. This structure ensures that the multi-stage filter cartridge 3 can be firmly embedded inside the dust collector body 1, while the handles facilitate the installation and disassembly of the multi-stage filter cartridge 3, thereby achieving the purpose of quickly replacing or cleaning the filter media 5, greatly simplifying the maintenance process, reducing downtime, and improving work efficiency. A gap is reserved between the outer wall of the multi-stage filter cartridge 3 and the inner wall of the dust collector body 1, and both sides of the outer wall of the dust collector body 1 are provided with opening and sealing doors 11. This structure ensures that the multi-stage filter cartridge 3 has sufficient space inside the dust collector body 1 for installation, disassembly, and maintenance operations, and also facilitates the adjustment of the height of the support ring 4.A sealing ring 12 is welded to the bottom of the dust collector body 1, and the bottom of the multi-stage filter cartridge 3 is in abutting contact with the top of the sealing ring 12. This structure of the sealing ring 12 not only provides a stable mechanical support, ensuring that the multi-stage filter cartridge 3 maintains a vertical and stable position within the dust collector body 1 and preventing it from shifting due to airflow impact or equipment vibration, but also forms an effective sealing interface through tight abutting contact with the bottom of the multi-stage filter cartridge 3. Both sides of the multi-stage filter cartridge 3 are provided with strip-shaped adjustment ports 13, and both sides of the outer edge of the strip-shaped adjustment ports 13 are welded and fixed with limiting edges 14. The support ring 4 is located on both sides of the strip-shaped adjustment port. Each joint 13 is welded with a retaining ring 15, and a positioning pin 16 is inserted between the retaining ring 15 and the limiting edge 14. The limiting edge 14 has several through holes that mate with the positioning pins 16. This structure allows the operator to adjust the height of the support ring 4 by adjusting the positions of the positioning pins 16 in different through holes on the limiting edge 14. The strip-shaped adjustment port 13 provides the necessary space and path for this height adjustment, ensuring that the support ring 4 can move up and down unimpeded inside the multi-stage filter cartridge 3. This allows each support ring 4 to be firmly fixed at the required height, ensuring that the filter media 5 is in the optimal working position.
[0018] Working Principle: When using this multi-stage dust removal and purification device for high-strength wear-resistant castable production, firstly, install the multi-stage filter cartridge 3 inside the dust collector body 1, ensuring that the bottom end of the multi-stage filter cartridge 3 is in abutting contact with the top of the sealing ring 12, and simultaneously ensuring that the snap-fit block 9 and the receiving block 10 are firmly embedded. Then, the top cover 2 can be closed. Next, the dust-laden airflow is introduced through the dust inlet on one side of the bottom end of the dust collector body 1. The airflow rises and enters the multi-stage filter cartridge 3. During this process, the airflow passes through three filter media 5 in sequence: a coarse particle interception layer, a medium particle capture layer, and a fine particle purification layer. Each filter media 5 effectively intercepts particulate impurities and dust of different particle sizes. At the same time, the exhaust pipe 6 passes through the bottom. The exhaust duct 7 leading to the outside of the dust collector body 1 is connected to an external fan, generating a negative pressure effect. This causes the airflow to continuously flow upward and periodically spray compressed air onto the filter medium 5 through several multi-position nozzles 8. These multi-position nozzles 8 allow the compressed air to be evenly dispersed and penetrate the part of the filter medium 5 with its circular plate structure that is sleeved on the outside of the exhaust duct 6, so that the dust attached to it is powerfully blown away. At the same time, in order to adapt to different working conditions, the operator can open the sealing door 11 and make independent adjustments through the cooperation between the strip adjustment port 13, the limiting edge 14, the fixing ring 15 and the positioning pin 16 to ensure that each filter medium 5 is in the optimal working position, thereby completing a series of tasks.
[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
