specific Embodiment approach 1

[0034] Combine below Figure 1-12 Describe this embodiment, the screening mechanism with adjustable sieve hole size includes a support frame 1, a differential assembly 2 and an auxiliary frame 6, the differential assembly 2 is fixedly connected to the support frame 1, and the auxiliary frame 6 is fixedly connected to the support frame 1 The lower end of the sieving mechanism with adjustable sieve hole size also includes a drive centrifugal assembly 3, an inner sieve bucket 4, an outer sieve bucket 5, an adjustment assembly 7, a push assembly 8, a solid-liquid separation assembly 9 and a sprinkler assembly 10. The centrifugal assembly 3 is fixedly connected to the differential assembly 2, the inner sieve bucket 4 is fixedly connected to the adjustment assembly 7, the adjustment assembly 7 is rotatably connected to the auxiliary frame 6, the outer sieve bucket 5 is rotatably connected to the adjustment assembly 7, and the push assembly 8 Fixedly connected to the adjustment assem...

specific Embodiment approach 2

[0037] Combine below Figure 1-12 To illustrate this embodiment, the differential assembly 2 includes an upper cover 2-1, a feed pipe 2-2, a differential shaft 2-3 and a differential wheel 2-4, and the upper cover 2-1 is fixedly connected to the support frame 1 The upper end of the feed pipe 2-2 is fixedly connected to the upper cover 2-1, and the lower part of the upper cover 2-1 is evenly distributed with a plurality of differential shafts 2-3, and the plurality of differential shafts 2-3 are rotationally connected There are differential wheels 2-4.

[0038] Feeding is carried out through the feed pipe 2-2, and the diameter of the feed pipe 2-2 controls the feeding speed of the sieved material, which can make the present invention in the best sieving state and prevent the material from being screened too quickly or In the case of material accumulation, multiple differential wheels 2-4 can reduce the high-speed rotation driven by the centrifugal assembly 3 to the low-speed rot...

specific Embodiment approach 3

[0040] Combine below Figure 1-12 To illustrate this embodiment, the drive centrifugal assembly 3 includes a drive frame 3-1, a drive motor 3-2, a drive gear 3-3, a rotating shaft 3-4 and a spiral plate 3-5, and the drive frame 3-1 is fixedly connected to On the upper cover 2-1, the drive motor 3-2 is fixedly connected to the drive frame 3-1, the drive gear 3-3 is fixedly connected to the output shaft of the drive motor 3-2, and the rotating shaft 3-4 is fixedly connected to the drive motor On the output shaft of 3-2, the spiral plate 3-5 is fixedly connected on the rotating shaft 3-4, and the spiral plate 3-5 is rotatably connected in the inner sieve bucket 4.

[0041] The driving motor 3-2 drives the driving gear 3-3 to rotate, and the driving gear 3-3 meshes to drive a plurality of differential wheels 2-4 to rotate, and the plurality of differential wheels 2-4 play a high rotational speed output by the driving motor 3-2 Reduce the speed to the lower rotation speed of the o...

Abstract

The invention relates to the technical field of screening equipment, in particular to a screening mechanism with adjustable screening hole size. The screening mechanism comprises a support frame, a differential speed assembly, a driving centrifugal assembly, an inner screen barrel, an outer screen barrel, an auxiliary frame, an adjusting assembly, a pushing assembly, a solid-liquid separation assembly and a water spraying assembly, the pushing assembly rotates to drive the adjusting assembly to rotate, the adjusting assembly rotates to drive the outer screen barrel to rotate, the coincidence degree of a plurality of large outer screen holes and a plurality of inner screen holes is adjusted, the coincidence degree of a plurality of small outer screen holes and a plurality of inner screen holes can be adjusted, substances can be separated and screened in different sizes, the substances to be screened can be screened at a certain speed by driving the centrifugal assembly, the centrifugalassembly is cooperatively driven to drive the outer screen barrel to rotate through the differential assembly, the outer screen barrel drives the inner screen barrel to rotate through the adjusting assembly, substances to be screened penetrate through overlapped screen holes in the inner screen barrel and the outer screen barrel to be separated and screened in size under movement, and the purposeof rapidly screening the screened substances is achieved.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a screening mechanism with adjustable screen hole size. Background technique [0002] The invention with the publication number of CN109225825A discloses a screening mechanism with adjustable mesh size. The mechanism uses a conveyor belt to replace the corresponding first conveyor belt with mesh holes of different sizes between the first driving wheel and the first driven wheel, thereby The size of the sieve hole can be adjusted, and the sieve holes on the first conveyor belt can meet the screening requirements of particles of different sizes. Since the whole replacement process is carried out automatically, the operation of replacing the screening frame can be simplified. The disadvantage of this invention is that the separation of materials with different sizes depends on the immovable sieve holes, and the sieving efficiency is too low. Contents of the invention ...
