[0029] The present application will be further elaborated in detail below with reference to the drawings and embodiments.

[0030] Refer to Figures 1 to 4 , the embodiments of the present application provide a coal gangue raw material processing and screening device, including a box body 1. A feeding assembly 2 and a dust removal assembly 3 are arranged on the top of the box body 1. A screen 4 is fixedly installed inside the box body 1. The feeding assembly 2 includes a vertical hopper 21. The vertical hopper 21 is fixedly installed on the top of the box body 1. A buffer plate 24 is rotatably connected inside the vertical hopper 21. A shock absorber 25 is hinged between the bottom of the buffer plate 24 and the left inner wall of the box body 1. The connection between the vertical hopper 21 and the box body 1 is located above the highest point of the screen 4. A first discharge hopper 6 is fixedly installed on the right side of the box body 1. The first discharge hopper 6 is communicated with the inside of the box body 1. The connection between the first discharge hopper 6 and the box body 1 is located at the lowest point on the right side of the screen 4.

[0031] A triangular hopper 22 is fixedly installed above the vertical hopper 21. A feeding groove 23 is formed on the left side of the triangular hopper 22. The triangular hopper 22 is communicated inside and outside through the feeding groove 23. The triangular hopper 22 is communicated with the inside of the vertical hopper 21. A guiding plate 5 is fixedly installed inside the box body 1. The highest point on the right side of the guiding plate 5 is located below the lowest point on the right side of the screen 4.

[0032] In this embodiment, before screening, feeding is carried out through the feeding groove 23 on the side of the triangular hopper 22. After the material enters the triangular hopper 22, it will enter the internal part of the lower vertical hopper 21 and fall onto the lower buffer plate 24. The shock absorber 25 at the bottom of the buffer plate 24 can absorb and buffer the acting force generated between the material and the buffer plate 24, thereby greatly reducing the acting force on the material when the material falls, reducing the probability of material fragmentation, and ensuring the quality of the material after screening.

[0033] Refer to Figures 1 to 4, in one aspect of this embodiment, a second discharge hopper 7 is fixedly installed on the left side of the box body 1. The second discharge hopper 7 is communicated with the inside of the box body 1, and the connection part between the second discharge hopper 7 and the box body 1 is located at the lowest point on the left side of the guide plate 5.

[0034] The dust removal component 3 includes a converging shell 31. The converging shell 31 is fixedly installed on the top of the box body 1. A dust suction hopper 34 is fixedly installed on the inner top of the box body 1, and the dust suction hopper 34 is communicated with the corresponding converging shell 31.

[0035] The dust removal component 3 further includes an industrial vacuum cleaner 35. A connecting pipe 32 is fixedly installed on the top of the converging shell 31. A main pipe 33 is fixedly installed between the tops of the connecting pipes 32, and the main pipe 33 is communicated with the inlet of the industrial vacuum cleaner 35.

[0036] In this embodiment, after the material is loaded, it falls onto the screen 4. The material rolls on the screen 4 to screen the material on the screen 4. The screened material falls onto the upper part of the lower guide plate 5 through the screen 4. The large-particle material remaining above the screen 4 is discharged through the first discharge hopper 6. The material passing through the screen 4 is discharged through the second discharge hopper 7 under the guidance of the guide plate 5, thus realizing the effect of material screening and separation. And when screening, by starting the industrial vacuum cleaner 35, the industrial vacuum cleaner 35 generates suction. The suction absorbs the air in the converging shell 31 and the dust suction hopper 34 through the main pipe 33 and the connecting pipe 32, and generates negative pressure inside the converging shell 31 and the dust suction hopper 34. Through the generation of negative pressure, the dust generated during screening below can be absorbed, and the dust is absorbed into the industrial vacuum cleaner 35 through the connecting pipe 32 and the main pipe 33, thus realizing the absorption of the dust generated during screening.

[0037] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Working principle: Before screening, the material is fed through the feeding chute 23 on the side of the triangular hopper 22. After the material enters the triangular hopper 22, it will enter the interior of the vertical hopper 21 below and fall onto the buffer plate 24 below. The shock absorber 25 at the bottom of the buffer plate 24 can absorb and buffer the force generated between the material and the buffer plate 24, thus greatly reducing the force exerted on the material when it falls, reducing the probability of material fragmentation, and ensuring the quality of the material after screening. After the material is fed, it falls onto the screen 4. The material rolls on the screen 4 for screening. The screened material falls onto the upper part of the guiding plate 5 below. The large-particle material remaining above the screen 4 is discharged through the first discharge hopper 6. The material passing through the screen 4 is discharged through the second discharge hopper 7 under the guidance of the guiding plate 5, thus achieving the effect of material screening and separation. And during screening, by starting the industrial vacuum cleaner 35, the industrial vacuum cleaner 35 generates suction. The suction absorbs the air in the converging shell 31 and the dust suction hopper 34 through the main pipe 33 and the connecting pipe 32, and generates negative pressure inside the converging shell 31 and the dust suction hopper 34. The negative pressure can absorb the dust generated during screening below, and the dust is absorbed into the industrial vacuum cleaner 35 through the connecting pipe 32 and the main pipe 33, thus achieving the absorption of the dust generated during screening.
