Description

Technical Field

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

[0002] Slag powder screening refers to the screening of slag powder by mechanical equipment to control and adjust the particle size and distribution of slag powder. The main purpose of slag powder screening is to remove impurities and unnecessary particles so that the slag powder meets specific standards and requirements. Through slag powder screening, the quality and particle size uniformity of the product can be improved.

[0003] For example, a slag powder screening device is disclosed in the utility model patent with announcement number CN220048891U, which relates to the technical field of slag powder screening devices, including a collecting bucket, a discharging port is fixedly connected to the bottom surface of the collecting bucket, a motor is fixedly connected to the inner wall of the collecting bucket, a mounting plate is fixedly connected to the output shaft end of the motor, a screening bucket is fixedly connected to the upper surface of the mounting plate, and a slide groove is provided on the inner wall of the screening bucket. The utility model has a reasonable design structure, and can solve the existing slag powder screening device through the cooperation between the motor, the screening bucket, the screening plate, the spring and the hydraulic rod. Generally, the slag powder is screened by the vibration of the motor screening net. The slag powder can only be screened out from the holes on the screening net by vibrating or vibrating the slag powder on the screening net left and right. However, since the slag powder to be screened is large, when the slag powder is screened only by the vibration of the screening net, the slag powder is likely to be unevenly screened due to accumulation.

[0004] However, in actual use, it was found that: multiple hydraulic rods of the device would rotate under the belt of the screening barrel, so that the external liquid supply pipeline could not be well connected with the hydraulic rod, thus affecting the normal use of the hydraulic rod;

[0005] Secondly, when the screening barrel rotates and uses centrifugal force to screen out smaller slag powder from the sieve holes, larger slag powder will also come into contact with the inner wall of the screening barrel under the action of the centrifugal force generated by the rotation of the screening barrel, which will block the sieve holes on the screening barrel and affect the screening of the slag powder.
