Description

Technical Field

[0001] The utility model relates to the technical field of powder and granule screening, and particularly relates to a powder and granule screening mechanism. Background Art

[0002] As is well known, a large particle screening mechanism for a powdery chemical raw material is an auxiliary device for screening a chemical particle mixture according to volume size, and it has been widely used in the field of particle screening; at present, due to actual needs, it is necessary to screen the chemical particles by size for different applicable areas. The processing method is usually manual screening, and tools such as manual sieve baskets are used. However, because a large amount of processing is required in the factory, the time efficiency of manual screening cannot meet the daily production needs. Moreover, the manual labor intensity is relatively large, the physical strength of employees is severely consumed, and it is not easy to work for a long time, resulting in poor reliability.

[0003] When screening powdery chemical particles, because they are powdery and light, they will adhere to the inner side of the screening box. Therefore, after screening, a large number of particles will remain on the inner wall of the screening box, which will cause waste of chemical raw materials. At the same time, because the powdery particles are easy to block the screening mesh, the screening efficiency will be reduced.

[0004] Therefore, a powder and granule screening mechanism is proposed. Content of the Utility Model

The main shaft end of the second motor 801 is connected with a connecting rotating rod 802. One end of the connecting rotating rod 802 is provided with a second cleaning plate 803 that fits against the inner wall of the screening net 7 and the screening box 6. A blowing member 9 is arranged on the screening box 6. The blowing member 9 includes an air pump 901 arranged at the top end of the screening box 6 and a blowing plate 904 arranged at the top end inside the screening box 6. The output end of the air pump 901 extends into the blowing plate 904. A plurality of air blowing pipes 905 are arranged on the blowing plate 904; specifically, the arranged screening net 7 can realize the screening of powder particles. The arranged vibration motor 701 can improve the screening efficiency. During screening, the arranged second cleaning member 8 works, which can drive the second cleaning plate 803 to rotate. The second cleaning plate 803 can brush the surface of the screening net 7, thus further improving the screening efficiency. During brushing, it can also clean the inner wall of the screening box 6 to prevent powder particles from adhering to its inner wall. At the same time, the arranged blowing member 9 works to blow gas into the screening box 6, thus preventing dust from rising upward. The screened powder particles can fall into the movable box 3. The blown gas can be discharged outward under the filtering action of the first filter screen 401. Under the action of the first cleaning member 5, the first cleaning plate 503 can continuously brush the surface of the first filter screen 401, thus preventing its filter holes from being blocked and affecting the discharge of gas.

[0025] As Figure 2 shown, a sealing door 101 is hinged on the collection box 1. A movable box 3 is movably arranged inside the collection box 1. The movable box 3 is arranged directly below the screening net 7.

The main shaft end of the first motor 502 is connected with a first cleaning plate 503; specifically, when the first motor 502 works, it can drive the first cleaning plate 503 to rotate. The rotation of the first cleaning plate 503 can continuously brush the surface of the first filter screen 401, thus scraping the powder thereon and facilitating the subsequent outward discharge of air.

[0027] As Figures 2-4As shown, the screening box 6 is designed in a funnel shape, and the inner wall of the screening box 6 is smooth; specifically, the screening box 6 is funnel-shaped and has a smooth surface, so that powder particles can be reduced from adhering to its surface.

[0028] As Figure 2 shown, the input end of the air pump 901 is threadedly connected with a connecting pipe 902, and a second filter screen 903 is arranged inside the connecting pipe 902; specifically, the arranged second filter screen 903 can filter the dust in the outside air to prevent the outside dust from entering the inside of the screening box 6. The connecting pipe 902 is threadedly arranged at the input end of the air pump 901, so that it can be conveniently replaced.

[0029] As Figure 2 shown, a feed pipe 601 is arranged on the screening box 6, and a sealing cover 602 is threadedly arranged on the feed pipe 601; specifically, the sealing cover 602 can conveniently seal the feed pipe 601, so that powder particles can be prevented from being discharged outward under the blowing action of the wind.

[0030] In summary: The arranged screening mesh 7 can realize the screening of powdery particles. The arranged vibration motor 701 can improve the screening efficiency. During screening, the arranged second cleaning member 8 works, which can drive the second cleaning plate 803 to rotate. The second cleaning plate 803 can brush the surface of the screening mesh 7, so that the screening efficiency can be further improved. During brushing, the inner wall of the screening box 6 can also be cleaned to prevent powdery particles from adhering to its inner wall. At the same time, the arranged blowing member 9 works to blow gas into the inside of the screening box 6, so that dust can be prevented from rising upward. The screened powdery particles can fall into the inside of the movable box 3. The blown gas can be discharged outward under the filtering action of the first filter screen 401. Under the action of the first cleaning member 5, the first cleaning plate 503 can continuously brush the surface of the first filter screen 401, so that its filter holes can be prevented from being blocked and affecting the discharge of gas.
