Description

Technical Field

[0001] The utility model relates to the technical field of slag powder screening, in particular to a slag powder screening device. Background Art

[0002] Slag powder is usually the crushed slag generated in mineral mining. Such crushed slag usually has certain uses. However, due to different sizes, it needs to be screened before transportation. By placing the slag powder inside the screening device, the slag with different apertures can be screened correspondingly by using the sieves in different spaces.

[0003] Chinese Patent Publication No.: CN217569675U published "A Slag Powder Screening Device", including a base. Above the base, there is a screening box. Four corners of the lower side wall of the screening box are fixedly connected with shock-absorbing columns. Four shock-absorbing cylinders are fixedly connected to the upper side wall of the base. The side walls on the opposite sides of the shock-absorbing cylinder and the shock-absorbing column are fixedly connected with the same first spring. Two first filter meshes are fixedly connected to the inner wall of the screening box. Two mutually connected thick powder discharge pipes are fixedly communicated with the left side wall of the screening box. The right side wall of the screening box is fixedly communicated with a discharge cylinder. When screening the slag powder, the slag powder is made to fall into the screening box little by little under the vibration of the screening box to avoid the problem that the slag powder accumulates above the first sieve and is likely to slide down from the thick powder discharge pipe, affecting the screening efficiency.

[0004] In the prior art during use, by using the cooperation of a ratchet and a ratchet tooth, the conveyor belt is driven to rotate by the up and down vibration, so as to uniformly introduce the internal stones into the screening box body. However, due to the fact that the feeding structure is located at a relatively high position outside, it is easy to spill during feeding, resulting in the problem that it cannot completely enter the screening box. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a slag powder screening device to solve the problem in the above background art that due to the fact that the feeding structure is located at a relatively high position outside, it is easy to spill during feeding, resulting in the problem that it cannot completely enter the screening box.
