AI Technical Summary
Traditional spiral drum screens lack diversion processing during feed screening, resulting in a large amount of raw material being added at once without smooth flow, which affects screening efficiency.
The system uses a drive motor to control the rotation of the bulk material impeller, guides the raw material to the screen with the guide plate, and controls the rotation of the shaft with a variable frequency motor and reducer to make the screen rotate. The crushing plate then breaks up the agglomerated raw material by impact.
It improves feed screening efficiency, ensures smooth flow of raw materials and effectively breaks up clumps, thus enhancing screening results.

[0024] This utility model provides a spiral drum screen for feed production. The drive motor controls the rotation of the bulk material impeller, and the guide plate guides the raw materials to the screens on both sides. The bulk material impeller also breaks up clumps of raw materials. The variable frequency motor and reducer control the rotation of the shaft, which in turn makes the screen rotate to screen the feed raw materials. The feed raw materials rotate inside the screen and collide with the breaking plate to further break up the clumps of feed raw materials and improve the screening efficiency.
[0025] Figures 1-2 The diagram shown is a structural schematic of one embodiment of the spiral drum screen for feed production according to this utility model. Please refer to [link / reference]. Figures 1-2 The spiral drum screen for feed production according to this embodiment includes a screening bin 100, a bulk material mechanism 200 and a screening mechanism 300 in its main body.
[0026] The screening bin 100 feeds raw materials to the inlet 101 through the feeding auger in the feeding channel 102. The raw materials fall from the inlet 101 onto the bulk material impeller 230. The screened coarse material is discharged from the coarse material outlet 120, and the fine material is fed through the mesh to the collection bin 110 and discharged through the discharge channel 111. Specifically, the screening bin 100 has an inlet 101 at the top and a collection bin 110 at the bottom. In this embodiment, the feeding channel 102 is provided at the top of the inlet 101, the discharge channel 111 is provided at the bottom of the collection bin 110, and the coarse material outlet 120 is provided at the bottom of the screening bin 100. The coarse material outlet 120 is located below the coarse material outlet 120 of the screen 350. The feeding auger is provided inside the feeding channel 102.
[0027] The bulk material mechanism 200 controls the rotation of the bulk material impeller 230 through the drive motor 220, and the guide plate 210 guides the raw material and sends it to the screens 350 on both sides. The bulk material impeller 230 also plays the role of breaking up agglomerated raw materials. Specifically, the bulk material mechanism 200 includes a guide plate 210 disposed below the feed inlet 101, a drive motor 220 disposed on the side wall of the guide plate 210, and a bulk material impeller 230 disposed at the output end of the drive motor 220.
[0028] The screening mechanism 300 uses a variable frequency motor 310 and a reducer 320 to control the rotation of the shaft 330, which in turn causes the screen 350 to rotate, thus screening the feed raw materials. The feed raw materials rotate inside the screen 350 and collide with the breaking plate 351, further breaking up the clumps of feed raw materials and improving screening efficiency. Specifically, the screening mechanism 300 includes a variable frequency motor 310 disposed on the side wall of the screening chamber 100, a reducer 320 disposed on the output end of the variable frequency motor 310, a shaft 330 disposed on the output end of the reducer 320, a connecting rod 340 disposed on the side wall of the shaft 330, and a screen 350 disposed on the side wall of the connecting rod 340. In this embodiment, the inner wall of the screen 350 is provided with a reinforcing ring, and the inner wall of the screen 350 is provided with a breaking plate 351. The bulk material impeller 230 is located below the feed inlet 101.
[0029] Combination Figures 1-2The specific usage process of a spiral drum screen for feed production in this embodiment is as follows: the feed raw materials are fed to the feed inlet 101 through the feeding auger in the feeding channel 102, and fall from the feed inlet 101 onto the bulk material impeller 230. The coarse material screened is discharged from the coarse material outlet 120, and the fine material is fed through the mesh to the collection bin 110 and discharged through the discharge channel 111. The bulk material impeller 230 is controlled to rotate by the drive motor 220, and the guide plate 210 guides the raw materials to the screens 350 on both sides. The bulk material impeller 230 also plays a role in breaking up agglomerated raw materials. The shaft 330 is controlled to rotate by the variable frequency motor 310 and the reducer 320, which in turn causes the screen 350 to rotate, thus screening the feed raw materials. The feed raw materials rotate inside the screen 350 and collide with the breaking plate 351, further breaking up the agglomerated feed raw materials and improving the screening efficiency.
