Description

Technical Field

[0001] The utility model relates to the technical field of ore powder screening, and particularly relates to a dust-free ore powder screening and separating device. Background Technique

[0002] Dust-free ore powder usually refers to an ore powder product that can effectively control the generation and diffusion of dust during the processes of processing, screening, transportation, etc. A dust-free ore powder screening and separating device is disclosed in Chinese Patent Publication No. CN 213468607 U, which includes a stable base. The middle end of the bottom of the inner cavity of the stable base is fixedly connected with a hinge block, the outside of the hinge block is hinged with a hinge seat, the top of the hinge seat is fixedly connected with a separation box, motors are fixedly installed on both the left and right sides of the stable base, the output end of the motor is fixedly connected with a rotating shaft, a cam is fixedly connected to the outer surface of the rotating shaft, and a bidirectional threaded rod, a first sieve plate and a second sieve plate are sequentially arranged in the inner cavity of the separation box from top to bottom.

[0003] In the above technical solution, the movable sleeve and the brush plate are driven by the bidirectional threaded rod to move, and the brush plate cleans the sieve plate to prevent blockage. However, the bidirectional threaded rod is arranged in the separation box. When the dust-free ore powder is vibrated and screened, a part of it may adhere to the bidirectional threaded rod, which will affect the driving of the brush plate, cause jamming between the bidirectional threaded rod and the movable sleeve, and it is inconvenient to evenly feed the dust-free ore powder. If too much ore powder is fed at one time, the screening efficiency will be affected. If less ore powder is fed, the worker needs to continuously feed the ore powder, and the feeding port cannot be sealed. When the dust-free ore powder is vibrated and screened, the dust-free ore powder may be emitted outward, resulting in waste and environmental pollution.

[0004] Therefore, a dust-free ore powder screening and separating device is proposed. Content of the Utility Model

[0032] In summary, during use, place the dust-free ore powder in the aggregate hopper 3, close the aggregate hopper 3 with the sealing cover 9, and at the same time start the first motor 5, the screening mechanism 6 and the cleaning mechanism 7. The first motor 5 drives the transmission column 4 to rotate, evenly conveying the dust-free ore powder in the aggregate hopper 3 into the screening barrel 2 and dropping it onto the screening mechanism 6. The screening mechanism 6 vibrates and screens the dust-free ore powder, and the cleaning mechanism 7 evenly brushes the screening mechanism 6 to prevent blockage.

The setting of the four elastic cloths 605 can prevent the dust-free ore powder from overflowing outward during screening, thereby sealing and screening the dust-free ore powder and avoiding waste. By starting the second motor 612, the connected shaft column 608 is driven to rotate, and the connected gear 610 rotates accordingly. The toothed belt 611 is the transmission center of the two gears 610, making the two gears 610 rotate synchronously, and the two shaft columns 608 rotate accordingly. By starting the third motor 701, the connecting cylinder 702, the limiting rod 704 and the cleaning brush 705 are driven to rotate, and the cleaning brush 705 evenly brushes the screening plate 601 to prevent blockage.

The dust-free ore powder passing through the screening falls into the collection box 806 for collection. When the collection box 806 is full, under the action of the weight, the connecting plate 802 slides on the fixed housing 1 and compresses the third spring 801, and one end of the connecting plate 802 presses on the control switch 804, and the control switch 804 starts the alarm 805 to issue an alarm, reminding the staff to transfer the dust-free ore powder in the collection box 806. By setting the quantity and orientation of the third springs 801, the stability can be improved.
