Technical Field

[0001] The utility model relates to the technical field of mine filling, in particular to a device for automatic tailings pit pulp making and filling. Background Technique

[0002] The backfilling of mine goaf needs to make filling slurry through a pit pulp making device. The pit pulp making device consists of a hopper and a conveyor belt. The material is poured into the hopper by a loader. After leaking onto the belt, the belt directly transports the material to the pit to make slurry.

[0003] The main raw materials for mine filling are different tailings sands, which are all fine materials, easy to agglomerate, and have a certain viscosity after moisture adjustment. They are easy to agglomerate and block the pump port after being made into slurry in the pit, affecting the filling rhythm. In the prior art, it is necessary to manually remove the agglomerated materials in the pit, but this method wastes manpower and the cleaning is not comprehensive enough. In addition, the concentration and liquid level of the pit slurry need to be monitored manually. When the liquid level exceeds the limit, it is necessary to manually turn off the belt conveyor, and the concentration control of the pit slurry depends on manual experience, which will cause unstable concentration and affect the filling quality.

[0004] Therefore, we propose a device for automatic tailings pit pulp making and filling to solve the above problems. Content of the Utility Model

A roller is arranged between the movable support and the filter mesh plate. The roller is rotatably connected to the inner side of the movable support. A driving mechanism is arranged on one side of the filtering frame. The driving mechanism is used to drive the roller to move along the length direction of the top surface of the filter mesh plate.

[0007] As an improvement of the above technical solution: a hopper is arranged at the bottom of the filtering frame, and a conveyor is arranged at the bottom of the hopper. The material in the filtering frame is introduced into the conveyor through the hopper, and the conveyor is used to introduce the material into the pit.

Four corners of the top of the hopper are fixedly connected with telescopic sleeve rods. The top ends of the telescopic sleeve rods are fixedly connected to the bottom end of the filtering frame. Springs are sleeved on the surfaces of the telescopic sleeve rods.

[0009] As an improvement to the above technical solution: both sides of the top of the filter box are provided with sliding grooves, both sides of the bottom of the movable bracket are each provided with a slider matching the sliding groove, and the bottom end of the slider is slidably connected to the sliding groove.

[0016] The beneficial effects of the present utility model:

[0017] 1. Before the material is fed, first place the material on the top of the filter mesh plate in the filter box. At the same time, control the driving mechanism through the controller to drive the crushing blocks to move back and forth repeatedly on the top of the filter mesh plate, and at the same time start the vibration mechanism to vibrate the material on the filter mesh plate, so that the material can be screened and the agglomerated material can be broken at the same time, ensuring that no agglomerated material enters the tailing sump, avoiding blockage of the pump port due to agglomeration after feeding, and avoiding affecting the production rhythm.
