[0018] In order to more clearly illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.
[0019] According to Figures 1-4 As shown, an automatic screening and impurity removing device for raw materials for PVC sheet production includes a base frame 1. A hopper 2 is fixedly installed on the base frame 1 through a bracket. A screw conveyor 3 is provided at the bottom of the hopper 2. A screening mechanism is provided on the side of the hopper 2. The screening mechanism includes a box body 4. A storage cavity 5 is provided inside the box body 4. The storage cavity 5 is communicated with the hopper 2 through the screw conveyor 3. A feeding roller 6 is movably installed in the storage cavity 5. A number of groups of turning hoppers 7 are arranged in an array on the feeding roller 6. A throwing port 8 is provided on the side of the storage cavity 5. A screening component is provided outside the throwing port 8.
[0020] In this embodiment, a feeding port 9 is opened at the bottom end of the storage cavity 5. The screw conveyor 3 is fixedly installed at the feeding port 9. The storage cavity 5 is of a circular structure. The end of the turning hopper 7 is closely attached to the inside of the discharge cavity. A motor 10 is fixedly installed on the outer wall of the box body 4. The power output shaft of the motor 10 is connected to the rotating shaft of the feeding roller 6. The raw materials in the hopper 2 are conveyed into the box body 4 through the screw conveyor 3. The raw materials enter the storage cavity 5 through the feeding port 9. Driven by the motor 10, the feeding roller 6 rotates clockwise. When the feeding roller 6 rotates, the raw materials are thrown from the throwing port 8 towards the screening component through the turning hopper 7.
[0021] In this embodiment, the screening assembly includes a fixing frame 11, on which a screen 12 is fixedly installed. The fixing frame 11 is inclined inside the box body 4, with the end away from the storage cavity 5 inclined downward. A blanking hopper 13 is fixedly installed at the bottom of the fixing frame 11, and the bottom surface of the blanking hopper 13 is parallel to the fixing frame 11. A support frame 14 is fixedly installed at the bottom of the blanking hopper 13, and a vibration motor 15 is fixedly installed on the support frame 14. An elastic telescopic rod 16 is fixedly installed at the bottom of the support frame 14, and the elastic telescopic rod 16 is fixedly installed on the bottom wall of the box body 4. Under the cooperation of the vibration motor 15 and the elastic telescopic rod 16, the support frame 14 drives the entire fixing frame 11 to vibrate up and down inside the box body 4, so as to vibrate and screen the raw materials through the screen 12. The impurities in the raw materials remain on the screen 12 and slide down, while the raw materials pass through the screen 12 and fall into the blanking hopper 13 for collection.
[0022] In this embodiment, a sealing gasket 17 is fixedly installed on the outer side wall of the fixing frame 11. A baffle plate 18 is provided between the fixing frame 11 and the storage cavity 5. The top end of the baffle plate 18 is welded at the throwing port 8. The baffle plate 18 abuts against the side wall of the fixing frame 11, and the other sides of the fixing frame 11 abut against the inner wall of the box body 4. The raw materials thrown out from the throwing port 8 fall onto the screen 12 for screening, and the sealing gasket 17 seals the gap between the fixing frame 11 and the box body 4.
[0023] In this embodiment, a discharge port 19 is opened on the outer wall of the box body 4 away from the storage cavity 5. A receiving hopper 20 is fixedly installed at the discharge port 19. The receiving hopper 20 is located below the blanking hopper 13, and the screened raw materials are guided outside the box body 4 through the receiving hopper 20 for collection.
[0024] In this embodiment, a collection box 21 is provided above the discharge port 19. The collection box 21 is fixedly installed on the outer wall of the box body 4. A suction pipe 22 is fixedly installed on the side wall of the collection box 21. A suction port 23 is opened on the side of the collection box 21 close to the box body 4. The suction port 23 is communicated with the inside of the box body 4. The suction port 23 is flush with the highest point where the fixing frame 11 rises. The impurities screened out by the screen 12 enter the collection box 21 through the suction port 23. The suction pipe 22 is connected to the air extraction assembly, and the impurities are sucked out of the collection box 21 through the air extraction assembly.
[0025] When the utility model is in use, the raw materials in the silo 2 are conveyed into the storage cavity 5 through the screw conveyor 3. The feeding roller 6 is driven to rotate by the motor 10. When the feeding roller 6 rotates, the raw materials are scattered from the throwing port to the screen 12 through the turning hopper 7. During the scattering process, the raw materials are fully dispersed and fall on the upper end of the screen 12. The fixing frame 11 is vibrated up and down by the vibration motor 15, so that the raw materials gradually slide to the bottom end of the screen 12 on the screen 12. The impurities in the raw materials are retained on the screen 12 and finally fall into the collection box 21. The raw materials pass through the screen 12 and fall onto the blanking hopper 13, and finally are discharged from the box body 1 through the receiving hopper 20.
