These raw materials are mixed with a lot of impurities when they are harvested. These impurities affect the reception, storage and processing of raw materials to varying degrees. For example, light impurities (organic impurities) fly, causing pollution to the working environment and even causing dust explosions; after entering the granary, the grains become hot, moldy and deteriorate; inorganic impurities enter the equipment, causing equipment damage and affecting normal production; affecting product purity and quality. Therefore, when receiving, storing and processing raw materials, enterprises have different cleaning requirements for impurities contained in grains according to different products produced, and require that light impurities be minimized when receiving and processing raw materials. Pollution to the environment caused by the environment.

[0003] The existing cleaning screen only screens the material once when in use, and is unable to screen materials of different sizes in layers. By screening the materials in layers, materials of different sizes can be layered, and the surface of the screen accumulates too much rubber left over from screening, which can easily clog the screen holes and cause inconvenience in cleaning, which has a certain adverse effect on people's use process. For this reason, we propose a multi-layer cleaning screen. Utility Model Content

[0024] Furthermore, the inner cavity of the screening device body 1 is fixedly installed with a first screening net 9, a second screening net 10 and a third screening net 11, and the first screening net 9 is located at the upper end of the second screening net 10, and the second screening net 10 is located at the upper end of the third screening net 11. A slag discharge trough 12 is provided on one side of the first screening net 9, the second screening net 10 and the third screening net 11. The screening efficiency is improved by the arrangement of the first screening net 9, the second screening net 10 and the third screening net 11.

[0025] Furthermore, the dust collection mechanism 3 includes a dust collector 301, a conveying pipe 302, a branch pipe 303 and an air nozzle 304. The lower end of the dust collector 301 is fixedly connected to the conveying pipe 302, the lower end of the conveying pipe 302 is fixedly connected to the branch pipe 303, and the lower ends of both sides of the branch pipe 303 are fixedly installed with air nozzles 304. Through the operation of the dust collector 301, dust and odor enter the conveying pipe 302 through the air nozzle 304, and then enter the dust collector 301 for purification and discharge.

[0026] Furthermore, the cleaning mechanism 8 includes a driving motor 801, a rotating rod 802, a connecting rod 803 and a cleaning brush 804. The upper end of the driving motor 801 is movably connected to the rotating rod 802, and the upper end of the rotating rod 802 is fixedly connected to the connecting rod 803. A cleaning brush 804 is fixedly installed on one side of the connecting rod 803. The driving motor 801 drives the rotating rod 802 to operate, so that the three groups of cleaning brushes 804 on one side of the connecting rod 803 clean the three groups of screening nets respectively, and then the slag is discharged into the slag discharge port through the slag discharge trough 12 and discharged from the slag discharge port.

[0027] Furthermore, the first slag discharge port 4, the second slag discharge port 5, and the third slag discharge port 6 are respectively fixed at the lower end of the slag discharge trough 12, which solves the problem that too much material left over from screening accumulates on the surface of the screen, which easily blocks the screen holes and is inconvenient to clean.

The dust and odor enter the conveying pipe 302 through the air nozzle 304 through the operation of the dust collector 301, and then enter the dust collector 301 for purification and discharge. The driving motor 801, the rotating rod 802, the connecting rod 803, and the cleaning brush 804 in the cleaning mechanism 8 cooperate with each other. The surfaces of the three groups of screening nets can be cleaned of materials left over from screening that are excessively accumulated. The rotating rod 802 is driven by the driving motor 801 to operate, so that the three groups of cleaning brushes 804 on one side of the connecting rod 803 clean the three groups of screening nets respectively, and the materials are discharged into the slag discharge port through the slag discharge groove 12 and discharged from the slag discharge port, thereby solving the problem that the surface of the screen is excessively accumulated with materials left over from screening, which easily clogs the screen holes and is inconvenient to clean. The screening efficiency is improved by setting the first screening net 9, the second screening net 10 and the third screening net 11.
