Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically a high-efficiency screening device for biomass briquette fuel production. Background Technology
[0002] Biomass briquettes mainly refer to materials other than grains and fruits, such as straw, wood cellulose, agricultural by-products, agricultural and forestry waste, and poultry and livestock manure and waste from animal husbandry production. Screening devices are used to screen these materials during the production of biomass briquettes.
[0003] According to a public notice (No. CN222587276U) of a high-efficiency screening device for biomass briquette fuel production, the above application uses hot gas to blow 360 degrees through a nozzle onto the areas of the first and second filter plates, making it difficult for fuel materials to adhere to the outer surfaces of the first and second filter plates, thereby improving the screening efficiency.
[0004] However, in actual use, the screen plate vibrates under the action of the vibrating motor without a corresponding limiting mechanism, causing the screen plate to adhere to the inner wall of the machine body and thus causing wear. This leads to unstable vibration effect of the screen plate and affects the screening effect. In view of this, we propose a high-efficiency screening device for biomass briquette fuel production.

The stabilizing mechanism 3 includes a movable groove 301, an elastic telescopic rod 302, a mounting block 303, a roller 304, a movable hole 305, a telescopic spring 306, a sleeve 307, and a ball 308.
[0024] In one embodiment of this utility model, the movable groove 301 is formed on the inner wall of the support 1, the side wall of the sieve plate 2 is fixedly connected to an elastic telescopic rod 302, the end of the elastic telescopic rod 302 is fixedly installed with an mounting block 303, the inner wall of the mounting block 303 is rotatably connected to a roller 304, the side wall of the mounting block 303 is provided with a movable hole 305, one end of the telescopic spring 306 is fixedly connected to the inner wall of the movable hole 305, the other end of the telescopic spring 306 is fixedly connected to a sleeve 307, and the inner wall of the sleeve 307 is provided with a ball 308.
[0025] Additionally, the promoting mechanism 4 includes a groove 401, which is formed on the side wall of the screen plate 2. A straight rod 402 is fixedly installed on the inner wall of the groove 401, and a sliding block 403 is provided on the arc surface of the straight rod 402. A connecting rod is hinged to the side wall of the sliding block 403, and the end of the connecting rod away from the sliding block 403 is hinged to the upper surface of the mounting block 303, thereby ensuring the stability of the mounting block 303 and making the mounting block 303 stably contact the inner wall of the support 1. A circular hole is formed on the surface of the sliding block 403, and the sliding block 403 is fitted onto the arc surface of the straight rod 402, allowing the sliding block 403 to move on the arc surface of the straight rod 402.
[0026] In this embodiment of the invention, the diameter of the sleeve 307 is matched with the diameter of the movable hole 305, allowing the sleeve 307 to move within the movable hole 305.
