A filter screen dismounting tool for a filter desander

ActiveCN224391031UImplement unilateralAchieve multi-side force applicationMetal-working hand toolsStructural engineeringMechanical engineering
This utility model relates to the field of filter-type sand separators and discloses a filter screen disassembly tool for filter-type sand separators. The tool includes a top plate, connecting parts, and at least two jacks. The connecting parts include connecting rods and several connectors. The connecting rods and connectors are detachably connected, and the connecting rods are fixedly connected to the top plate. The connectors are adapted to the filter screen. The jacks are centrally symmetrically arranged on the circumference of the top plate. This utility model provides a modular filter screen disassembly tool, addressing the problems of easily damaged filter screens and numerous disassembly tools in filter-type sand separators. It designs a disassembly device composed of a top plate, connecting parts, and multiple jacks. The connecting parts use replaceable connectors to adapt to different filter screen specifications. By applying force from one or more sides with the centrally symmetrically installed jacks, the filter screen is deformed evenly under force, achieving eccentric pull-out and avoiding damage caused by violent disassembly. This reduces the types of tools, lowers the filter screen damage rate, improves work efficiency and safety, and effectively saves costs.

A coal and gangue separating and conveying device in a mine

This invention relates to the technical field of material conveying and discloses an underground coal and gangue separation and conveying device, including a first conveying component, a screening component, and a separation component. The first conveying component includes a first rotary drive and a first belt, with the first rotary drive connected to the first belt. The screening component includes a screening drive and a screening plate. The screening drive is used to drive the screening plate to move along a preset trajectory, and the first rotary drive can drive the first belt to move, so as to convey the load on the first belt to the screening plate. The separation component includes a first inclined track, a first monitoring component, and a force-applying drive. The first inclined track is located below the outlet of the screening plate. The first monitoring component is used to acquire an image of the load falling from the outlet of the first inclined track. The force-applying drive applies an external force to the gangue in the load according to the image to change the falling trajectory of the gangue, thereby realizing the separation of coal and gangue.
