Description

Technical Field

[0001] The utility model relates to the technical field of pretreatment of perforated bricks, and more specifically to a pretreatment device for perforated bricks before sintering. Background Art

[0002] The pretreatment of porous bricks is generally coal gangue pretreatment. Coal gangue is solid waste discharged during the coal mining and coal washing processes. Coal gangue bricks are building materials produced by the sintered brick process using coal gangue as a binder. In the process of producing coal gangue bricks, the coal gangue needs to be pretreated in advance to facilitate auxiliary processing into coal gangue bricks for use in construction. In order to make better use of coal gangue, some pretreatment of the coal gangue is required. For example, when using coal gangue to sinter porous bricks, the coal gangue needs to be crushed first. The degree of crushing directly affects the sintering quality of the porous bricks.

[0003] Patent application publication number: CN216964870U A pre-sintering pretreatment device for sintered porous bricks of coal gangue is used to start the motor through the control button on the controller. The motor rotates, and the crushing cylinder is driven to rotate through the rotating shaft. The coal gangue is poured into the feed port, and the coal gangue enters between the screen cylinder and the crushing cylinder. The coal gangue is gradually ground into powder through the extrusion effect between the screen cylinder and the crushing cylinder. The powder that meets the requirements falls from the sieve hole into the crushing chamber, so that the coal gangue placed therein is crushed by the extrusion effect between the crushing cylinder and the screen cylinder, which greatly improves the crushing efficiency and makes the coal gangue crushing effect better.

[0004] However, in actual use, the structure crushes the gangue into powder by means of the extrusion between the crushing cylinder and the screen cylinder, and then falls through the screen holes into the crushing chamber, but the larger powder will be stuck inside the screen holes, thereby blocking the screen holes and affecting the use effect.
