[0029] With reference to Figure 2 and Figure 5The dust collection assembly 8 includes a collection pipe 81. The upper end of the filter box 1 is threadedly connected to the collection pipe 81. A fan 82 is fixedly connected to the upper end of the collection pipe 81. The lower end of the collection pipe 81 is threadedly connected to a mounting plate 83. The upper end of the mounting plate 83 contacts a lifting plate 84. Multiple sets of circularly distributed cloth strips 86 are fixedly connected to the upper end of the lifting plate 84. A filter plate 87 is fixedly connected inside the collection pipe 81. The collection pipe 81 is made of corrosion-resistant materials such as metal or plastic. The threaded connection facilitates the installation and disassembly of the collection pipe 81, making it convenient for later maintenance and cleaning of the dust collection assembly 8. As the power source of the dust collection assembly 8, 82 can generate strong suction to draw the dust generated in the filter box 1 into the collection pipe 81. The mounting plate 83 serves to support and fix other components. The lifting plate 84 can move up and down under the action of the airflow generated by the fan 82. The cloth strip 86 is made of soft material and moves under the action of airflow to clean the lower end of the filter plate 87 and prevent the filter plate 87 from clogging. The filter plate 87 is made of high-precision filter material, which can intercept dust and only allow air to pass through, thereby collecting the dust in the collection pipe 81 and realizing air-dust separation.

[0030] Reference Figure 2 and Figure 5 The lower end of the lifting plate 84 is fixedly connected to two sets of symmetrically distributed limiting rods 85, and the two sets of limiting rods 85 are slidably connected to the mounting plate 83 respectively. The limiting rods 85 are made of metal material and have high strength and rigidity. The mounting plate 83 is provided with a sliding groove that matches the limiting rods 85. The limiting rods 85 can slide up and down in the sliding groove. This design enables the lifting plate 84 to maintain a stable movement trajectory during up and down movement without deviation or tilting. At the same time, the limiting rods 85 can also limit the movement range of the lifting plate 84 to prevent it from moving excessively and damaging other components.

[0031] Reference Figure 1 and Figure 2 The filter box 1 has multiple sets of symmetrically distributed sealing doors 9 inside its side wall. All sets of sealing doors 9 are made of transparent material. A discharge plate 10 for discharging material is fixedly connected to the side wall of the filter box 1. The sealing doors 9 are made of high-strength, transparent materials such as plexiglass or polycarbonate. The choice of transparent material allows operators to directly observe the working conditions inside the filter box 1, promptly detect problems such as screen blockage and material accumulation, and take appropriate measures. At the same time, the sealing door 9 and the filter box 1 adopt a sealed structure design, which can effectively prevent material leakage and dust overflow, and ensure the sealing and stability of the filtration process. The discharge plate 10 for discharging material is fixedly connected to the side wall of the filter box 1. The discharge plate 10 adopts an inclined design, and its inclination angle is determined according to the flow characteristics of the material, which can smoothly and quickly discharge the qualified high-alumina bauxite material from the filter box 1, facilitating subsequent processing and treatment.

[0032] Working principle: The high-alumina bauxite material to be processed is poured into the feed hopper 2, allowing the material to enter the filter box 1 smoothly and quickly, reducing clogging and spillage. After the material enters the filter box 1, the hollow shaft motor 3 is started. The hollow shaft motor 3 drives the hollow rod 51 to rotate synchronously. The multiple sets of scraper rods 52 on the outside of the hollow rod 51 rotate accordingly. These scraper rods 52 closely adhere to the surface of the first screen plate 6 and the second screen plate 7 during rotation, comprehensively and thoroughly scraping off the attached material, preventing accumulation and clogging, and ensuring the permeability of the first screen plate 6 and the second screen plate 7.

[0033] When the filtration process has been running for a certain period of time or when a tendency for the sieve plate to become clogged is observed, the high-pressure gas pipe 4 delivers high-pressure gas to the hollow rod 51 through the rotary joint. After the gas enters the hollow rod 51, it is distributed to multiple sets of ventilation rods 53 that are connected to it. The elastic plate 54 inside the ventilation rod 53 undergoes slight deformation when the high-pressure gas passes through, changing the direction and speed of the gas flow, and backflushing the first sieve plate 6 and the second sieve plate 7 to prevent the first sieve plate 6 and the second sieve plate 7 from becoming clogged.

[0034] Under the action of the fan 82, the airflow drives the lifting plate 84 to rise. The dust generated during the filtration process is sucked into the collection pipe 81. The annular cloth strip 86 at the upper end of the lifting plate 84 swings accordingly, cleaning the lower end of the filter plate 87 to prevent the filter plate 87 from clogging. The filter plate 87 intercepts the dust and only allows air to pass through, realizing air-dust separation and collecting the dust in the collection pipe 81.

[0035] After screening, the qualified high-alumina bauxite material is discharged smoothly and quickly from the filter box 1 through the inclined discharge plate 10, which facilitates subsequent processing. Operators can directly observe the working condition inside the filter box 1 through the sealed door 9 made of transparent material, and promptly detect and deal with problems such as screen plate blockage and material accumulation, so as to ensure the long-term stable operation of the device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
