[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-6The device shown is a dry cleaning apparatus for coarse boron carbide particles. It includes multiple support frames 2, which support the entire apparatus to ensure stability during operation and prevent shaking from affecting the cleaning and screening effects. Multiple feeding cylinders 1 are arranged between the support frames 2. The feeding cylinders 1 serve as the initial storage and preliminary processing space for the coarse boron carbide particles, accommodating a certain amount of material. The multiple feeding cylinders 1 are fixedly connected to form a unified material processing area. The feeding cylinders 1 are fixedly connected to the support frames 2 to ensure their position remains fixed during operation and does not shift. The same screening component is installed inside each feeding cylinder 1, which can screen and classify the coarse boron carbide particles to meet the needs of different particle sizes. A connecting guide cylinder 3 is fixedly connected to the outside of each feeding cylinder 1. The guide cylinder 3 transports the screened material from the feeding cylinder 1 to a mixing drum 4. Its interconnected design ensures efficient material transfer. To ensure smooth operation and reduce material blockage, the end of the feed cylinder 3 furthest from the feed cylinder 1 is fixedly connected to a connected mixing cylinder 4. The mixing cylinder 4 can stir and clean the screened boron carbide coarse particles. Stirring allows the particles to fully contact the cleaning medium, removing impurities attached to the particle surface and improving the cleaning effect. The screening assembly includes a first filter plate 9, a second filter plate 10, and a third filter plate 11 set inside the feed cylinder 1. The first filter plate 9, the second filter plate 10, and the third filter plate 11 are spliced ​​together and inclined. The inclined setting facilitates the automatic sliding of materials under gravity, realizing continuous screening and improving screening efficiency. The filter hole diameter of the first filter plate 9, the second filter plate 10, and the third filter plate 11 increases sequentially. This design can classify and screen the boron carbide coarse particles according to their particle size to obtain particle products of different specifications. The filling cylinder 1 has slots inside that fit the first filter plate 9, the second filter plate 10, and the third filter plate 11. These slots provide installation space for the filter plates, ensuring accurate and stable installation. A single rubber ring 16 is installed on the outer side of each of the first, second, and third filter plates 9 and 11. The rubber ring 16 is fixedly connected to the inner wall of the filling cylinder 1, acting as a seal to prevent material leakage from the gaps between the filter plates and the inner wall of the filling cylinder 1. It also buffers and dampens vibrations, reducing damage to the filter plates. Vibration motors 17 are installed on the outer side of each of the multiple filling cylinders 1. These motors provide power for the screening process, causing the material to continuously bounce on the filter plates through vibration, improving screening accuracy and efficiency. The output ends of the vibration motors 17 are fitted with rubber rings 16, and the output ends of the multiple vibration motors 17 are connected to the first, second, and third filter plates 9 and 11 respectively, ensuring that the vibrations generated by the vibration motors 17 are accurately transmitted to the filter plates, driving them to vibrate.

[0025] Example 2: Reference Figure 1-6Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a motor 5 is fixedly connected to the top of the mixing drum 4, and the output end of the motor 5 passes through the mixing drum 4. The motor 5 serves as a power source, converting electrical energy into mechanical energy to drive the output end to rotate, providing power for the entire mixing process and ensuring that the material in the mixing drum 4 can be fully mixed, thereby improving mixing efficiency and quality. A rotating rod 12 is fixedly connected to the output end of the motor 5, and multiple stirring rods 13 are fixedly connected to the outside of the rotating rod 12. The rotating rod 12 rotates under the drive of the motor 5, causing the stirring rods 13 to move synchronously. The stirring rods 13, through their own agitation, cause the material in the mixing drum 4 to move relative to each other in different directions and positions, thereby achieving uniform mixing of the material and effectively avoiding local accumulation or insufficient mixing of the material. Multiple interconnected dust guide pipes 6 are fixedly connected to the outside of the mixing drum 4. Each end of the multiple dust guide pipes 6 away from the mixing drum 4 is provided with a dust collection bag. A dust filter screen 15 is fixedly connected to the inner side of the dust guide pipe 6, and a centrifugal fan 14 is provided on the inner side of the dust guide pipe 6. During the mixing process, dust is generated. When the centrifugal fan 14 is working, it generates suction to draw the dust-laden air in the mixing drum 4 into the dust guide pipe 6. The dust filter 15 can intercept dust particles, allowing clean air to be discharged. The intercepted dust enters the dust collection bag through the dust guide pipe 6 for collection, effectively reducing dust overflow, lowering the dust concentration in the working environment, and ensuring the health of operators and environmental cleanliness. The end of the mixing drum 4 away from the feed cylinder 3 is fixedly connected to a connected output pipe 8. A solenoid valve 7 is installed at the connection between the mixing drum 4 and the output pipe 8. The solenoid valve 7 can precisely control the output of materials in the mixing drum 4. When it is necessary to discharge the mixed materials, the solenoid valve 7 is opened, and the materials flow out through the output pipe 8 under the action of gravity or other pressure. When it is not necessary to discharge, the solenoid valve 7 is opened. When feeding materials, close the solenoid valve 7 to prevent material leakage, achieve flexible control of material output, and ensure the orderly progress of the production process. The feeding cylinder 1 is fixedly connected to the support frame 2, and the outer side of the stirring rod 13 is covered with a polytetrafluoroethylene layer. The feeding cylinder 1 and the support frame 2 are fixedly connected to provide a stable support structure for the entire stirring device, ensuring the stability of the device during the stirring process and avoiding the impact of shaking on the stirring effect and equipment safety. The polytetrafluoroethylene layer on the outer side of the stirring rod 13 has good non-stick and wear resistance. On the one hand, it can prevent materials from adhering to the surface of the stirring rod 13, reduce material residue, and facilitate cleaning. On the other hand, it can effectively reduce the friction between the stirring rod 13 and the material, extend the service life of the stirring rod 13, and also reduce the energy consumption during the stirring process.

[0026] The working principle of this utility model is as follows: The material is introduced into the feeding cylinder 1 equipped with the first filter plate 9. The material is filtered multiple times by the inclined first filter plate 9, second filter plate 10, and third filter plate 11. Multiple vibration motors 17 are controlled to drive the corresponding filter plates to vibrate, thereby improving the filtration effect. Materials with different particle sizes are guided into different mixing cylinders 4. Multiple motors 5 are controlled to drive the corresponding rotating rods 12 and stirring rods 13 to rotate, thereby stirring the material and removing dust from the material surface. Multiple centrifugal fans 14 are controlled to generate suction to extract the dust. The dust filter 15 filters the material, and the dust is collected by the dust collection bag fitted on the outside of the dust guide pipe 6, thereby achieving dry cleaning of the material.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
