Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically to a screening machine with dust removal function. Background Technology

[0002] A screening machine is a device used to separate materials according to different particle sizes. It is usually composed of components such as a vibrator, a screen, and a hopper. Vibration causes the material to be screened in layers on the screen, thereby achieving the separation of materials of different particle sizes.

[0003] Chinese Patent CN216631486U discloses a dustproof tea sieving machine, including a screen, a dust cover, and a motor. The dust cover is fixed to the frame and covers the outside of the screen. A ventilation duct is provided at the upper end of the dust cover, and an exhaust fan is installed inside the ventilation duct. An electrostatic dust removal plate is installed on the inner side wall at the lower end of the dust cover. The beneficial effects of this invention are: in the dustproof tea sieving machine of this invention, the semi-enclosed structure of the dust cover suppresses dust emission; when the exhaust fan is activated, dust is drawn into the ventilation duct due to a local pressure difference; dust emitted below the screen is adsorbed by the electrostatic dust removal plate. The dust is both drawn into the ventilation duct and collected, and also adsorbed by the electrostatic dust removal plate, thus improving the dustproof effect of the tea sieving machine.

[0004] However, in the above technical solution, dust is collected only by setting a dust cover, an exhaust fan and an electrostatic dust removal plate above the screen. But when the electrostatic dust removal plate collects a certain amount of dust and forms a certain thickness, the adsorption effect of the electrostatic dust removal plate decreases, causing some dust to fall directly.

At the same time, the dust removal component can contact the collecting cylinder when it moves to both ends of the frame, so that the dust accumulated in the collecting cylinder can be poured into the bottom of the frame for centralized collection and discharge.

One end of the connecting frame 9 is connected to the moving seat, the scraper 10 is connected to the connecting frame 9, and the symmetrically arranged collecting cylinders 11 are connected to both sides of the connecting frame 9. In use, the connecting frame 9, the scraper 10, and the collecting cylinder 11 reciprocate along the reciprocating screw 8, and the scraper 10 contacts the electrostatic dust removal plate 7. The dust removal component includes a squeezing block 12 and a trigger rod 13. The symmetrically arranged squeezing block 12 is connected to the sealing plate 2, and the symmetrically arranged trigger rod 13 is connected to the collecting cylinder 11. In use, the squeezing block 12 pushes the trigger rod 13 to slide and remove dust from the collecting cylinder 11.

[0028] In an optional embodiment, the frame 1 consists of a housing 14, a support base 15, and an elastic element 16. The support base 15 is provided with multiple support legs, and each support leg is connected to an elastic element 16. The elastic element 16 is connected to the housing 14. The vibration motor 4 is connected to the housing 14. The housing 14 has multiple discharge ports corresponding to the filter screen 6.

[0029] Example 2

[0030] like Figures 2-4 As shown, the present invention proposes a screening machine with dust removal function. Compared with Embodiment 1, this embodiment describes the detailed structure of the moving component and the dust removal component. The moving component also includes a driving device 17, a cooperating rod 18 and a sliding seat 19. The driving device 17 is connected to the sealing plate 2 and is rotatably connected to one end of the reciprocating screw 8. The driving device 17 is a motor. The cooperating rod 18 is arranged parallel to the reciprocating screw 8. Both ends of the cooperating rod 18 are connected to the sealing plate 2. The sliding seat 19 is slidably connected to the cooperating rod 18 and is connected to the other end of the connecting frame 9.

[0031] In an optional embodiment, the collecting cylinder 11 consists of a fixed cylinder 20 and a movable cylinder 21. The fixed cylinder 20 is connected to the connecting frame 9, and the two symmetrically arranged movable cylinders 21 are hinged or pivotally connected to the fixed cylinder 20.

[0033] In summary, when using this utility model, the operator feeds the material into the frame 1 from the feed hopper 3, and simultaneously starts the vibration motor 4. The vibration motor 4 drives the housing 14 to vibrate, thereby causing the multi-layer filter screen 6 to filter the material. The material is classified through the filter screen 6 with different diameter mesh sizes. The screened material is discharged from each outlet. The dust generated during screening is adsorbed by the activated electrostatic dust removal plate 7. After starting the drive device 17, the output end of the drive device 17 drives the reciprocating screw 8 to rotate. The moving seat moves along the reciprocating screw 8 and drives the sliding seat 19 to slide on the mating rod 18 through the connecting frame 9. The scraper 10 on the connecting frame 9 comes into contact with the dust and removes it. The dust is scraped off and falls into the moving cylinder 21. When the collecting cylinder 11 moves to one end of the frame 1, the trigger rod 13 on the moving cylinder 21 will contact the squeezing block 12 with a triangular cross section. The squeezing block 12 will cause the trigger rod 13 to drive the sliding block 24 to slide inside the fixed cylinder 20. When the sliding block 24 moves, it lifts one end of the moving cylinder 21 with its triangular shape, causing it to rotate around the hinge. The collected dust is poured into the bottom of the frame 1 by tilting the moving cylinder 21. At the same time, when the sliding block 24 moves, it will drive the guide block 23 to slide on the guide rod 22 and compress the spring. When the trigger rod 13 moves away from the squeezing block 12, the spring rebounds and returns it to its original position.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
