Embodiment 1

[0039] see Figure 1-2As shown, a particle size multi-level processing mechanism for coal samples includes a primary treatment box 10 and a secondary treatment box 20, the primary treatment box 10 and the secondary treatment box 20 are arranged side by side, and the primary treatment box 10 and the secondary treatment box 10 are arranged side by side. The left side of box 20 is all provided with material-lifting pipeline 30, and one side of two material-lifting pipelines 30 is all provided with material guide pipe 40, and one end of two material guide pipes 40 extends to primary treatment box 10 and secondary treatment box 10 respectively. Inside the processing box 20, the material-lifting pipeline 30 adopts a pneumatic pipeline, and the coal sample to be processed is sent from the storage box into the interior of the multi-stage processing mechanism by using the material-lifting pipeline 30. Compared with the traditional screw feeding method, adopting The pneumatic pipeline c...

Embodiment 2

[0042] see Figure 2-3 As shown, in the present invention, the inside of the first-level treatment box 10 and the second-level treatment box 20 is provided with a sieve assembly, and the sieve assembly includes a sieve rack 201, and the bottom of the sieve rack 201 and the inner wall of the first-level treatment box 10 The bottom is fixedly connected, and an installation frame 202 is provided above the inside of the sieve frame 201, and a blanking trough 203 is provided inside the installation frame 202, and a screen 204 is provided inside the blanking chute 203. The coal sample processed by the roller 103 passes through the discharge hole and enters the inside of the discharge trough 203. The coal sample inside the discharge trough 203 has a particle size that meets the mesh diameter of the sieve 204 and directly passes through the sieve 204, and the particle size is larger than the sieve. The mesh diameter of the net 204 is left on the top of the screen 204, and the mesh dia...

Embodiment 3

[0044] see Figure 4-5 As shown, the inside of the primary treatment box 10 and the secondary treatment box 20 in the present invention are all provided with a pressing assembly, and the pressing assembly is located above the sieve assembly, the pressing assembly includes a pressing frame 301, and the pressing frame Both sides of the 301 bottom are provided with connecting frames 302, and the insides of the two connecting frames 302 are all rotated to be provided with nip rollers 303, and the two nip rollers 303 arranged below the nip frame 301 can be used to clean the inside of the blanking trough 203. The coal sample is subjected to secondary crushing treatment, so that the coal sample left on the top of the screen 204 can quickly pass through the screen 204 and fall into the bottom of the screen 204, so as to realize the unified control of the particle size of the coal sample. The primary treatment box 10 and The inside of secondary treatment box 20 is all slidably provided...

Abstract

The invention discloses a granularity multi-stage treatment mechanism for coal samples. The mechanism comprises a first-stage treatment box and a second-stage treatment box, the first-stage treatment box and the second-stage treatment box are arranged side by side, and the left side of the first-stage treatment box and the left side of the second-stage treatment box are both provided with a material lifting pipeline. The invention relates to the technical field of coal treatment. The coal sample granularity is subjected to multi-stage treatment through the first-stage treatment box and the second-stage treatment box, pressing assemblies are arranged in the first-stage treatment box and the second-stage treatment box, the coal samples are subjected to secondary crushing through pressing rollers, and the coal samples left above a screen fall into the lower portion of the screen. Moreover, when meshes of the screen are blocked by the coal samples, the surfaces of the pressing rollers can be attached to the upper surface of the screen by adjusting the position of a pressing frame, then the coal samples in the screen are extruded out through the rotating pressing rollers, and the situation that the screen is blocked is treated. The coal sample granularity multistage treatment efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to a particle size multi-stage processing mechanism for coal samples. Background technique [0002] At present, the coal grading technology is getting more and more mature. The existing Chinese invention patent publication number CN107899707A proposes a coal crushing and grading equipment. In this scheme, the coal is cut into pieces by crossing the dynamic crushing knife and the fixed crushing knife, and then passes through the first screening frame. and the second screening frame to classify the crushed coal, but after cross-crushing the coal with the dynamic crushing knife and the fixed crushing knife, the particle size of the coal is difficult to control, and after passing through the first screening frame and the second 2. When the coal particle size is classified by the screening frame, the coal with larger particle size will easily block the discharge port of the scree...
