Description

Technical Field

[0001] This utility model specifically relates to the field of screening and impurity removal technology, and more specifically to a chemical raw material screening and impurity removal feeding device. Background Technology

[0002] Screening and impurity removal devices are important processing equipment for separating chemical raw materials. Chemical raw materials are diverse and widely used, and different chemical production processes have strict requirements on indicators such as particle size and purity of raw materials. Screening and impurity removal can effectively separate powder from internal impurities in raw materials, ensuring the smooth operation of subsequent production processes and preventing impurities from clogging the equipment. Currently, traditional chemical raw materials are typically screened using screening devices for impurity removal. After simple screening, a small amount of powder may still remain inside the impurities, requiring the conveying device to perform repeated screening processes. This results in low equipment efficiency. Furthermore, traditional screening and impurity removal devices cannot simultaneously convey the raw materials during the impurity removal process; they can only achieve centralized conveying after the raw materials have been thoroughly screened, which affects the equipment's feeding efficiency. With the increasing requirements for raw material screening and impurity removal, devices have emerged that can remove impurities during the raw material transportation process. However, traditional automatic impurity removal devices directly remove the powder mixed in with the impurities after the impurity removal is completed during the transportation process, which will cause raw material waste and cannot guarantee the overall quality of the raw materials. Traditional devices cannot achieve the effect of completely separating the powder remaining in the impurities. A search revealed that Chinese patent application CN202021738728.1 discloses a feed processing screening and impurity removal device; it includes an impurity removal box, an impurity removal trough inside the impurity removal box, a feed inlet on the top wall of the impurity removal trough, a feed pipe fixedly installed inside the feed inlet, a filter box with a hollow bottom wall inside the impurity removal trough, a filter groove inside the filter box, a first filter screen and a second filter screen fixedly installed between the inner side walls of the filter groove, the first filter screen being larger than the second filter screen, a drive mechanism and a telescopic mechanism being respectively provided on the left and right sides of the filter box, and a feed box slidably placed below the filter box inside the impurity removal trough; When screening raw materials, the device in the aforementioned patent separates powder from impurities through a filter box inside the impurity removal box. However, after screening the impurities, a small amount of powder may still remain inside the impurities. The device in the aforementioned patent cannot transfer the impurities back to the feed pipe. Therefore, the impurities can only be removed and screened again after the raw materials are screened, which results in low screening efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a chemical raw material screening and impurity removal feeding device. In this device, the raw material is added to one end of the screening plate inside the shell. The auger roller drives the brush to rotate, achieving the effect of forward conveying of the raw material. During the conveying process, the brush contacts the powder and impurities in the raw material, achieving the effect of sweeping the impurities forward. The powder falls into the collection box through the screening holes at the bottom of the screening plate, while the impurities are concentrated and conveyed to the three-way connector. Through the cooperation of the blower and the conveying pipe, the impurities are conveyed back to the feeding end, achieving the effect of circulating screening of the residual powder in the impurities; thus solving the problems of the above-mentioned background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A chemical raw material screening and impurity removal feeding device includes a shell; a screening plate is fixedly installed on the inner wall of the shell; the screening plate is U-shaped; multiple sets of screening holes are opened on the screening plate; a collection box is located between the screening plate and the side wall at the bottom of the shell; and a discharge port is opened at the bottom of the collection box. The screening plate is fitted with a auger roller; the two ends of the auger roller are movably mounted to the two ends of the housing via bearings; and brushes are fixedly mounted on the spiral blades of the auger roller.

[0005] As a further technical solution of this utility model, a material outlet is provided on the side wall of one end of the shell to facilitate the discharge of impurities, and the material outlet is fixedly installed with a three-way connector; the two ends of the three-way connector are respectively fixedly installed with a blower and a transmission pipe.

[0006] As a further technical solution of this utility model, one end of the rotating shaft of the auger roller extends to the outside of the shell and is fixedly installed with a driven sprocket; the driven sprocket is connected to the driving sprocket through a chain; the driving sprocket is fixedly installed on the output shaft of the drive motor; the drive motor is fixedly installed on the top plate at one end of the shell.

[0007] As a further technical solution of this utility model, the end of the transmission tube away from the tee connector extends to the top of the feeding end of the housing.

[0008] As a further technical solution of this utility model, multiple sets of screening holes are opened on the U-shaped surface at the bottom of the screening plate; the interior of the screening plate is connected to the collection box.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In this invention, chemical raw materials are added to the inside of the screening plate. The drive motor, through the active sprocket and chain, enables the driven sprocket at the end of the auger roller to rotate. As the auger roller rotates, the raw materials are transported forward, and impurities are screened simultaneously during the transport process. In this invention, when the auger roller rotates, the brush on the edge of the auger roller achieves the effect of cleaning the raw material, thereby separating the powder from the impurities. The separated powder falls into the collection box at the bottom of the shell through the screening holes at the bottom of the screening plate, realizing centralized feeding and transmission of the separated material. In this invention, the separated impurities are transported to the material inlet at the end of the shell through the rotation of the auger roller and brush, and then enter the interior of the three-way connector. Through the cooperation between the blower and the transmission pipe, the impurities are transported to the material end of the screening plate through the transmission pipe, so as to further screen the impurities and avoid the residual powder in the impurities from affecting the overall processing quality of the raw materials.
