Description

Technical Field

[0001] This utility model relates to the field of cyclone dust collectors, and in particular to a high-temperature resistant, wear-resistant rigid refractory layer and its cyclone dust collector. Background Technology

[0002] A cyclone dust collector is a device that uses centrifugal force to separate dust particles from dust-laden airflow. Its working principle involves the high-speed rotating airflow generating a strong centrifugal force, causing denser dust particles to be thrown against the collector wall and then fall into the ash hopper under gravity, thus achieving gas-solid separation. A cyclone dust collector mainly consists of an inlet pipe, an outlet pipe, a cylindrical body, a conical body, and an ash hopper. It has advantages such as simple structure, convenient maintenance, low cost, and large air volume handling capacity, and is widely used in dust recovery and waste gas treatment in industrial production, such as metallurgy, chemical industry, and building materials industry.

[0003] A search revealed a Chinese patent announcement number: CN220879242U, which discloses a cyclone dust collector. By setting the outer dust collection box and the inner dust collection box to be open on one side, and then moving a movable box is installed inside the inner dust collection box. The opening of the movable box is connected to the lower end of the dust collector body, so that the user can directly remove the movable box to empty all the dust from the inner dust collection box, avoiding the problem of dust not being completely emptied.

[0004] The aforementioned equipment uses an outer dust collection box and an inner dust collection box to collect dust and prevent it from being unable to be emptied. However, the equipment lacks a structure to increase rigidity and stiffness, causing the equipment to be subjected to impacts under high-speed airflow for a long time. At the same time, the weight of the equipment itself causes local deformation, resulting in reduced durability. To address these issues, a high-temperature resistant, wear-resistant, rigid refractory layer and its cyclone dust collector are proposed. Utility Model Content

The system includes an anti-static layer 9, which is applied last to effectively reduce the generation and accumulation of static electricity, lowering the risk of fire or explosion caused by static electricity. It is especially suitable for handling flammable and explosive dust. The system also includes a cyclone dust collector body 1.

This structure can effectively resist the impact and vibration of the high-speed airflow inside the cyclone dust collector body 1, enhance the stability and rigidity of the equipment, reduce deformation and displacement during operation, and extend the service life of the equipment.

[0035] Reference Figures 4-7The bottom of the cyclone dust collector body 1 is provided with a support plate 10, and four sets of casters 11 are arranged in a rectangular array at the bottom of the support plate 10 for easy movement. A collection box 12 is provided at the top of the support plate 10, and a self-priming drawer is provided inside the collection box 12 to collect dust discharged from the ash hopper of the cyclone dust collector body 1. A telescopic pipe 14 is fixedly connected to the top of the collection box 12, and a fixing ring 13 is fixedly connected to the top of the telescopic pipe 14. The fixing ring 13 can be fitted onto the outer wall of the ash hopper of the cyclone dust collector body 1. After the dust is discharged by the automatic ash discharge device on the ash hopper, it is collected by the collection box 12. An annular air... The inner wall of the annular airbag 17 is fixedly connected to an air supply pipe 16. A portion of the air supply pipe 16 is retractable.

The bottom of the air pump 15 is fixedly connected to the top of the support plate 10. A fixing rod 18 is slidably connected to the inner wall of the fixing ring 13. A fixing spring 19 is fixedly connected to the outer wall of the fixing ring 13. A groove 21 is opened on the outer wall of the cyclone dust collector body 1. The outer wall of the fixing rod 18 is adapted to the inner wall of the groove 21. A magnetic sheet 20 is fixedly connected to the inner wall of the groove 21. The end of the fixing rod 18 away from the fixing spring 19 is magnetically connected to the side wall of the magnetic sheet 20.

[0036] Reference Figure 7 A mounting bracket 22 is fixedly connected to the top of the support plate 10. The mounting bracket 22 is located on the outer wall of the support plate 10 near the air pump 15. A motor 23 is fixedly connected to the top of the mounting bracket 22. A cam 24 is fixedly connected to the output end of the motor 23 through a rotating shaft. The cam 24 rotates at a speed controlled by the motor 23. When the cam 24 rotates once, it exerts a squeezing force on the collection box 12. A sliding groove 25 is opened on the top of the support plate 10. A sliding rod 26 is fixedly connected to the inner wall of the sliding groove 25. A telescopic spring 27 is fixedly connected to the inner wall of the sliding groove 25. The telescopic spring 27 is sleeved on the outer wall of the sliding rod 26. The bottom of the collection box 12 is slidably connected to the outer wall of the sliding rod 26 through support legs. There are four sets of support legs. The two sets of support legs are located inside the two sets of sliding grooves 25 and are slidably connected to the two sets of sliding rods 26. Each set of sliding grooves 25 is equipped with four sets of telescopic springs 27. The four sets of telescopic springs 27 are in pairs, and the opposite ends are fixedly connected to the two sets of support legs.

[0037] Working Principle: Multiple sets of spiral wire mesh 3 and a set of coiled wire mesh 4 inside the cyclone dust collector body 1 form an integrated structure, distributing the stress across the multiple sets of spiral wire mesh 3, avoiding localized stress concentration, reducing the burden on individual spiral wire mesh 3, and improving the overall structural load-bearing capacity. This allows the equipment to better adapt to harsh working environments. Combined with the insulation layer 5, high-temperature resistant layer 6, wear-resistant rigid fire-resistant layer 7, corrosion-resistant layer 8, and anti-static layer 9, the equipment's durability is improved. Using casters 11, the support plate 10 is moved below the ash discharge hopper. The fixing ring 13 is placed outside the ash discharge hopper. The fixing rod 18 is compressed by the outside of the ash discharge hopper, causing the fixing spring 19 to stretch. When the fixing ring 13 moves the fixing rod 18 closer to the groove 21, the elasticity of the fixing spring 19 causes the fixing rod 18 to embed into the groove 21 and engage with the magnetic field. The plate 20 is magnetically attracted, thereby connecting the telescopic tube 14 to the ash discharge hopper through the fixing ring 13. At this time, the air pump 15 is started, and the air pump 15 inputs air into the annular air bag 17 through the air supply pipe 16. After the annular air bag 17 gradually expands, it seals and covers the tiny gap between the fixing ring 13 and the ash discharge hopper. The automatic ash discharge device of the ash discharge hopper is started, and the dust enters the telescopic tube 14 through the ash discharge hopper and is collected in the collection box 12. At this time, the motor 23 slowly drives the cam 24 to rotate, so that it squeezes the collection box 12. The collection box 12 slides on the slide rod 26. After the elastic force of the telescopic spring 27 pushes the collection box 12 back to its original position, it receives the squeezing force again, so that it moves back and forth on the surface of the support plate 10 to shake off the dust collected inside, so as to prevent the dust from accumulating at the ash discharge port inside the collection box 12.
