Description

Technical Field

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

[0002] Patent application number 202320858048.0 discloses a slag screening device, including a shell, a receiving frame and a support assembly. Through the coordinated use of the feed pipe, short auger, feed pipe and drive assembly on the feed assembly, the slag can be discharged through the feed pipe on the feed pipe during screening, so that the slag can be better spread on the filter plate for filtering and screening, thereby ensuring the efficiency of slag screening.

[0003] Although the above disclosed technical solution can spread the slag on the filter plate, the slag cannot be completely spread on the filter plate. This is mainly reflected in that when the slag falls, a circular area will be formed on the filter plate directly below the feed pipe and the discharge pipe, and the slag cannot fall directly into this area. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a slag screening device, which drives the distribution pipe to swing back and forth by an electric telescopic rod, so that the slag can be completely spread on the entire filter plate, avoiding the phenomenon that the slag cannot fall into a certain area of ​​the filter plate.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A slag screening device comprises a screening box body, two filter plates are arranged on the inner side of the screening box body, a discharge pipe corresponding to the filter plate is connected to the right side of the screening box body, a hopper is fixedly connected to the top of the screening box body, a rubber telescopic hose is fixedly connected to the top of the screening box body, the top end of the rubber telescopic hose is connected to the opening at the bottom of the hopper, a mounting plate is fixedly connected to the upper part of the inner wall of the screening box body, a cloth pipe is rotatably connected to the side of the mounting plate, the top end of the cloth pipe is connected to the bottom of the rubber telescopic hose, an electric telescopic rod is hinged on the mounting plate, and the telescopic end of the electric telescopic rod is hinged to the cloth pipe.

[0007] Furthermore, the bottom of the inner cavity of the screening box body is set as an inclined slope, and a discharge port is opened at the bottom of the screening box body at the lowest point of the slope.

[0008] Furthermore, the flat rectangular tube body of the distribution tube has a length that is the same as the distance between the front and rear sides of the filter plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The electric telescopic rod pushes the cloth pipe to swing back and forth, so that the slag can be completely spread on the entire filter plate, avoiding the phenomenon that the slag cannot fall into a certain area of ​​the filter plate.

[0011] 2. By tilting the bottom of the screening box body, the filtered slag can be discharged directly, avoiding the need for auger discharge. The distribution pipe is adapted to the filter plate to facilitate the discharge of slag, avoiding areas on the filter plate where material cannot fall. BRIEF DESCRIPTION OF THE DRAWINGS
