[0020] Reference Figure 1-4The utility model provides a screening device for lactose powder production: it includes a base 1, a screening device 2 is arranged on the upper end of the base 1; a screening net 3 is embedded in the inner upper end of the screening device 2; two discharge plates 4 are arranged on the inner and outer sides of the screening device 2; a discharge pipe 5 is arranged on the lower end of the discharge plate 4 away from the screening device 2; the lactose powder after production is poured into the screening plate in the screening device 2, and after the screening device 2 is started, the screening device 2 vibrates, and the screening plate screens the lactose powder at the upper end and divides it into two types, and the qualified ones are discharged through the discharge pipe 5 on one side, and the unqualified ones are discharged through the discharge pipe 5 at the rear end.
[0021] Among them, a mounting ring 6 is provided on the outer side of the discharge pipe 5; a dustproof cloth 7 is provided at the lower end of the mounting ring 6; a fixing component 10 is provided inside the mounting ring 6. When the device is used, the mounting ring 6 with the dustproof cloth 7 is fixed to the discharge pipe 5. When the screening device 2 is started, the screened lactose is discharged through the discharge plate 4 at the front end, and the powdery product passes through the discharge plate 4, the discharge pipe 5, the mounting ring 6 and the dustproof cloth 7, and finally falls into the collection box through the dustproof cloth 7. The dustproof cloth 7 can prevent the lactose powder from floating in the air when it falls during discharge.
[0022] It should be noted that the device needs to connect its own power supply to an external power supply when in use. After the connection is completed, the lactose powder produced will be manually poured into the screening device 2 through the storage box, and the screening device 2 will screen the lactose powder of different particle sizes.
[0023] As a further implementation scheme of the above technical solution: Figure 3-4 As shown, sliding rings 8 are provided at both upper and lower ends of the mounting ring 6; a pushing block 9 is provided at one end of the sliding ring 8 close to the center of the mounting ring 6; the pushing block 9 is located inside the mounting ring 6, and when installing the dustproof cloth 7, the sliding ring 8 is inserted into the discharge pipe 5 from bottom to top until the sliding ring 8 is inserted to the desired position.
[0024] As a further implementation scheme of the above technical solution: Figure 3-4 As shown, the fixed component 10 includes a sliding block 1001, and the end of the sliding block 1001 away from the discharge pipe 5 is set at a 45-degree inclined surface, the end of the pushing block 9 that contacts the sliding block 1001 is set at the same inclined surface as the sliding block 1001, and the pushing block 9 is slidably connected to the sliding block 1001. When the dustproof cloth 7 needs to be installed, the sliding ring 8 is manually rotated, and the sliding ring 8 drives the internal pushing block 9 to rotate clockwise, and the end of the pushing block 9 close to the sliding block 1001 is inclined to each other, so when the pushing block 9 rotates clockwise with the sliding ring 8, the sliding block 1001 moves to the position in the discharge pipe 5.
[0025] As a further implementation scheme of the above technical solution: Figure 3-4 The end of the sliding block 1001 away from the pushing block 9 is fixedly connected with a snap-fit block 1002, and the snap-fit block 1002 penetrates the mounting ring 6, and the snap-fit block 1002 is slidably connected with the mounting ring 6 and the discharge pipe 5. When the sliding block 1001 moves inside, the snap-fit block 1002 will be stuck in the reserved groove provided in the discharge pipe 5, so that the snap-fit rod can be stuck in the discharge pipe 5 to fix it.
[0026] As a further implementation scheme of the above technical solution: Figure 3-4 As shown, both upper and lower ends of the sliding block 1001 are fixedly connected with a fixed shaft 1003, and the outer side of the fixed shaft 1003 is fixedly connected with a spring hook 1004, and the end of the spring hook 1004 away from the pushing block 9 is fixedly connected with a connecting block 1005, and the connecting block 1005 is fixedly connected to the mounting ring 6. When the sliding block 1001 moves toward the center position under the action of the pushing block 9, the spring hook 1004 on the outer side of the fixed shaft 1003 is stretched, and the sliding ring 8 is threadedly connected to the mounting ring 6. Therefore, when the sliding ring 8 drives the pushing block 9 to rotate clockwise, the sliding ring 8 and the mounting ring 6 are threadedly fixed and tightened. When the sliding ring 8 rotates clockwise when loosened, the spring hook 1004 is reset to pull the sliding block 1001 to the position of the pushing block 9, which is convenient for moving the engaging rod away from the discharge pipe 5, thereby allowing the dustproof cloth 7 to be removed from the discharge pipe 5.
[0027] As a further implementation scheme of the above technical solution: Figure 1-4 As shown, the dustproof cloth 7 is made of non-woven fabric, and the dustproof cloth 7 is fixedly connected to the mounting ring 6. When receiving the material, the dustproof cloth 7 is installed in the discharge pipe 5, and the lower end of the dustproof cloth 7 is placed in the collecting box. The screening device 2 is started to screen the lactose powder, and the lactose powder falls into the collecting box through the dustproof cloth 7. After the screening is completed, it can be removed, and the mounting ring 6 can be shaken back and forth to shake off the lactose powder inside the dustproof cloth 7.
