Description

Technical Field

[0001] This utility model belongs to the field of biomass treatment technology, and in particular relates to a sealed biomass drum screen. Background Technology

[0002] According to the published patent CN221360996U, a rotary drum screen for biomass fuel production includes a frame, screen box, bearing seats, rotating shaft, motor, screen cylinder, and feeding hopper. The frame is lower at the front and higher at the rear. The screen box is installed at an angle on the frame. The bearing seats are installed on the frame at the front and rear ends of the screen box. The rotating shaft is rotatably mounted to bearings on the bearing seats at both ends. The motor is installed on the frame and connected to the front end of the rotating shaft via a power output end. The screen cylinder is located inside the screen box. This design solves the problem of material clumping during the rotation screening process of traditional rotary drum screens, resulting in poor screening efficiency. The clumped material is removed from the end of the screen cylinder along with large particles of impurities. However, it still has the following shortcomings:

[0003] The aforementioned equipment achieves the effect of breaking up the raw materials and allowing them to leak through the screen holes. However, biomass raw materials are usually non-uniform and may contain large lumps. If these large lumps directly enter the screening process, it may cause screen blockage or incomplete screening, resulting in poor screening effect due to differences in particle size. This leads to a waste of more time and energy for remedial measures. Therefore, we propose a sealed biomass drum screen. Utility Model Content

[0004] The purpose of this invention is to provide a sealed biomass drum screen. Through an anti-clogging mechanism and a squeezing mechanism, it solves the problem that while the aforementioned equipment achieves the effect of breaking up the raw material and allowing it to leak through the screen holes, biomass raw materials are usually non-uniform and may contain large lumps. If these large lumps directly enter the screening process, it may cause screen blockage or incomplete screening, resulting in poor screening performance due to particle size differences, thus wasting more time and energy on remedial measures.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sealed biomass drum screen, including a base plate, a fixing frame fixedly connected to the top outer wall of the base plate, a sealing box fixedly connected to the outer wall of the fixing frame, and an anti-blocking mechanism provided on the outer wall of the fixing frame;

[0007] The anti-blocking mechanism includes a fixed plate, the outer wall of which is fixedly connected to the outer wall of a fixed frame. A first motor is fixedly connected to the inner wall of the fixed plate. A rotating shaft is fixedly connected to the bottom output end of the first motor via a coupling. Several connecting frames are fixedly connected to the outer wall of the rotating shaft. A drum screen is fixedly connected to the outer wall of each of the connecting frames. The outer wall of the drum screen is rotatably connected to the inner wall of the sealed box.

A second pulley is driven to the outer wall of the belt. A crushing roller is fixedly connected to the inner wall of the second pulley.

[0008] Furthermore, a feed box is rotatably connected to the outer wall of the crushing roller, the outer wall of the feed box is fixedly connected to the outer wall of the sealing box, and a plurality of crushing rollers are rotatably connected to the inner wall of the feed box. A gear is fixedly connected to the outer wall of the crushing roller located on the left side.

[0009] Furthermore, a second gear is fixedly connected to the outer wall of the crushing roller on the right side, and the outer wall of the second gear meshes with the outer wall of the gear. A pressing mechanism is provided on the top outer wall of the bottom plate.

[0010] Furthermore, the extrusion mechanism includes a collection box, the bottom outer wall of which is fixedly connected to the top outer wall of the base plate, a motor fixing plate is fixedly connected to the outer wall of the collection box, a second motor is fixedly connected to the inner wall of the motor fixing plate, and a rotating shaft is fixedly connected to the bottom output end of the second motor via a coupling.

[0011] Furthermore, a turntable is fixedly connected to the outer wall of the end of the rotating shaft away from the second motor, and a connecting shaft is fixedly connected to the outer wall of the turntable away from the rotating shaft.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a second pulley. When the second pulley rotates, it drives the crushing roller to rotate, which in turn drives the gear to rotate. When the gear rotates, it drives the second gear to rotate, which in turn drives the other crushing roller to rotate. The two crushing rollers then crush the biomass, achieving the effect of pre-treating the biomass into particles suitable for screening, thereby improving the screening effect and effectively avoiding problems such as uneven screening or screen clogging caused by excessively large particles.

[0017] 2. This utility model incorporates a turntable. When the turntable starts to rotate, it drives the connecting shaft to rotate. When the connecting shaft starts to rotate, it drives the connecting rod to move back and forth. At this time, the connecting rod drives the extrusion plate to move along the same trajectory through the positioning shaft. When it comes into contact with the biomass, it pushes it to one side, achieving the effect of compressing and compacting the biomass so that it can be tightly bound together, thus facilitating subsequent transportation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

When the connecting shaft 306 starts rotating, it drives the connecting rod 307 to move back and forth. At this time, the connecting rod 307 drives the extrusion plate 310 to move along the same trajectory through the positioning shaft 309. When it comes into contact with the biomass, it pushes it to one side so that it can fit tightly together, thus facilitating subsequent transportation.
