[0027] The present application provides an integrated processing and screening device, comprising: a processing unit 1, a dust removal unit 2 and a material receiving unit 3.

[0028] Please also refer to Figure 1 and Figure 2 , the processing unit 1 can be Figure 1 The one shown in FIG includes a crusher 10 and a hopper 11. It can also be Figure 2The dry granulator 12 and vacuum loader 13 are shown. The dry granulator 12 extrudes the material via rollers 14. The dust removal unit 2 includes a dust removal box 20, which includes a dust removal chamber 21 and a side filter 22 located on the side of the dust removal chamber 21. The dust removal chamber 21 is connected to the outlet of the processing unit 1 to receive the material processed by the processing unit 1. The dust removal chamber 21 is provided with a middle filter 23, which includes a middle filter chamber 24. The side wall of the middle filter 23 includes a first sieve plate 25 connecting the dust removal chamber 21 and the middle filter chamber 24. The side filter 22 includes a side filter chamber. The side wall of the side filter 22 includes a second sieve plate 26 connecting the dust removal chamber 21 and the side filter chamber. The inlet of the material receiving unit 3 is connected to the outlet of the dust removal chamber 21. The material receiving unit 3 may include a material receiving drum 30. After the material is received in the material receiving drum 30, it enters the next processing flow. The first sieve plate 25 and the second sieve plate 26 are both provided with a plurality of sieve holes for screening materials, dust and debris.

[0029] In the embodiment of the present application, the processing unit 1 and the dust removal unit 2 can be tightly connected using a quick-connect chuck structure.

[0030] By integrating the processing unit 1, the dust removal unit 2, and the material collection unit 3, the present application can realize the effect of material processing (crushing or forming) to dust removal and final collection in a continuous and closed environment, thereby improving production efficiency, avoiding secondary pollution caused by manual transfer of materials between the processing unit 1 and the dust removal unit 2, and reducing manual labor intensity. In addition, the middle filter 23 and the side filter 22 provided in the dust removal unit 2 effectively utilize the internal space of the dust removal box 20, realize secondary dust removal of the material, and improve the compactness and efficiency of the material dust removal and slag removal structure.

[0031] As an optional embodiment, the middle filter 23 is in the shape of a quadrangular prism, the middle filter chamber 24 is located in the middle of the dust removal chamber 21, and one of the two opposite edges of the middle filter 23 faces the outlet of the processing unit 1 and the other faces the inlet of the receiving unit 3. The first sieve plates 25 are provided on the four side walls of the middle filter 23, that is, four first sieve plates 25 are provided on the middle filter 23. Figures 1 to 2As shown, the middle filter chamber 24 is located in the middle of the dust removal chamber 21, which means that each outer surface of the middle filter chamber 24 is spaced from the wall of the dust removal chamber 21 to increase the contact area between the material and the first screen plate 25. The processed material falls from the processing unit 1 into the dust removal unit 2 below under the action of gravity. When the material passes through the surface of the middle filter 23, it is split into two left and right paths by the edge of the middle filter 23 facing the processing unit 1, and slides on the surface of the first screen plate 25 along an inverted "V" route. During the sliding process, the fine powder and debris entrained in the material fall into the middle filter chamber 24 through the sieve holes of the first screen plate 25, thereby achieving preliminary dust removal and slag removal of the material, and realizing continuous online dust removal of the material.

[0032] As an optional embodiment, the dust removal unit 2 also includes a rotating shaft, one end of which is connected to the end face of the middle filter 23, and the other end is mounted on a driving mechanism; among the four first sieve plates 25, the sieve hole diameters on two adjacent first sieve plates 25 are the same and smaller than the sieve hole diameters on the other two adjacent first sieve plates 25. The driving mechanism in the embodiment of the present application can be a driving motor, or it can be a magnet mounted on the other end of the rotating shaft and an iron stone mounted on the outer wall of the dust removal box 20, which drives the magnet to rotate by rotating the iron stone and thereby drives the rotating shaft to rotate. By driving the rotating shaft by 180°, the two adjacent first sieve plates 25 with the same and larger apertures can be rotated from facing the processing unit 1 to two adjacent first sieve plates 25 with the same and smaller apertures facing the processing unit 1, so as to achieve the effect of adjusting the first sieve plates 25 with different sieve hole diameters according to the diameter of different materials and the situation of carrying dust and debris, thereby improving the targetedness and dust removal effect of screening dust removal and slag removal. And the entire process does not require the replacement of the middle filter 23, saving time and effort.

[0033] As an optional embodiment, the wall of the dust removal box 20 can be made transparent to facilitate external observation and adjustment of the position of the filter 23 to achieve a better dust removal effect.

In this embodiment of the present application, the four chamber walls of the dust removal chamber 21 and the four side walls of the middle filter 23 with the first sieve plates 25 are arranged in a one-to-one correspondence, and can cooperate with the middle filter 23 to achieve the effect of diverting and directing the material to both sides of the middle filter 23.

[0035] As an optional embodiment, the side filters 22 are provided on two adjacent side walls at the bottom of the dust removal chamber 21, and the two second sieve plates 26 are both arranged toward the middle filter 23. When the material falls or slides down from the middle filter chamber 24 to the location of the side filters 22 under the action of gravity, the fine powder and debris remaining in the material are further filtered out by the sieve holes in the second sieve plates 26. The secondary dust removal effect of the second sieve plates 26 can significantly improve the dust and slag removal effects.

[0036] As an optional embodiment, a slide rail is provided on the side of the dust removal box 20, and a slider is provided on the side filter 22. The slider slides on the slide rail to enable the side filter 22 to be removable. In this embodiment of the present application, the side filter 22 is plugged into the dust removal box 20 through the cooperation of the slide rail and the slider, and the side filter 22 can be removed and replaced to meet the dust removal requirements of different materials.

By passing a purge gas into the side filter chamber through the second backflush pipe, dust or residue attached to the second sieve plate 26 or the wall of the side filter chamber can be blown away in the reverse direction, thus avoiding clogging of the second sieve plate 26, preventing scaling of the side filter chamber, and improving the cleanliness of the side filter 22. In the embodiment of the present application, the first backflush pipe, the second backflush pipe 29, the first dust suction pipe 27, and the second dust suction pipe 28 work in an alternating manner. That is, the first dust suction pipe 27 and the second dust suction pipe 28 are vacuumed for a period of time (for example, 20S) and then stop working, and then the first back-blowing pipe and the second back-blowing pipe 29 are opened for a period of time (for example, 2S) to quickly purge, and then the first dust suction pipe 27 and the second dust suction pipe 28 are opened again to vacuum according to the above-set time; repeat the above steps to achieve vacuum dust removal and slag removal of the middle filter 23 and the side filter 22, and prevent dust and residue deposition, thereby improving the dust removal effect and dust removal efficiency. As an optional embodiment, a purge part or a cleaning part is provided in the dust removal box 20.

The mounting end 51 is installed at the outlet of the dust removal box 20, and the anti-overflow end 52 extends into the material receiving unit 3 and abuts against the inner wall of the material receiving unit 3. Please refer to Figure 1 The overflow prevention plate 50 can be conical, and the overflow prevention end 52 extends to the inner wall of the material receiving unit 3, which can guide the material into the material receiving unit 3, preventing the material from stacking at the joint between the dust suppression cover 5 and the material receiving unit 3 and overflowing from the material receiving unit 3 after the dust suppression cover 5 is removed from the material receiving unit 3, thereby increasing the material recovery rate.

[0041] As an optional embodiment, a one-way guide plate is provided inside the dust suppression cover 5.
