Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine powder production, in particular to an ultrafine powder production screening device which is convenient for material feeding. Background Art

[0002] After searching, the Chinese patent publication number is CN215088854U, and the publication date is 2021-12-10. It discloses a screening device for processing silicon carbide ultrafine powder, including: a screening box, a feed hopper and a top cover. The interior of the screening box is located at the top and fixedly connected to a No. 1 screening net, and a No. 2 screening net is fixedly connected below the No. 1 screening net, and a No. 3 screening net is fixedly connected below the No. 2 screening net. By setting a dust suction structure, when the screening is finished, the residual impurities in the screening net can be cleaned through the dust suction structure, and the cleaned impurities can be temporarily stored, and can be easily taken out after the screening is finished, which is very convenient. However, when the device is in use, the raw materials are directly poured into the screening box. Since too much raw material is poured in at one time, a large amount of raw material will instantly accumulate on the top screening net, which will cause the screening net to be blocked, thereby affecting the screening efficiency. In addition, the poured raw materials will clump, and the existing method cannot sieve the lumped raw materials, resulting in a large amount of raw material being wasted. It is not only time-consuming and labor-intensive, but also cannot guarantee the screening effect. Utility Model Content

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] The working principle of the utility model is as follows: by turning on the first motor 81 and the second motor 11, the fixed plate 92 is driven to rotate through the disc 82, thereby driving the protrusion 96 to rotate. The protrusion 96 will be stuck in the groove 94 during the rotation.

At the same time, under the action of the transmission assembly 18, the first motor 81 drives the rotating rod 16 to rotate, thereby driving the cam 17 to rotate, and pouring the raw materials into the feed hopper 2. Under the action of the blocking plate 95, the raw materials in the feed hopper 2 are intermittently sent to the box body 1. After unloading, the raw materials fall on the upper guide trough 5, and the pressure roller 12 is used to roll the raw materials to break the agglomerated raw materials. After that, the raw materials will fall on the screening slot plate 7, and under the action of the cam 17 and the spring 19, the screening slot plate 7 is driven to reciprocate, and the shaking of the screening slot plate 7 is used to further screen the rolled raw materials. Some large particles of raw materials will slide down along the screening slot plate 7 and then be discharged through the first discharge trough 3, while small particles of raw materials will fall on the lower guide trough 6 and slide down along the lower guide trough 6, and then be discharged through the second discharge trough 4, thereby avoiding incomplete screening and reducing the screening effect, making it convenient for the screened raw materials to slide out of the screening device, and at the same time, unqualified raw materials can be effectively collected.
