Abstract

The invention discloses a screening mechanism for coal. The screening mechanism comprises a bottom plate and a shell, and the shell is fixedly connected to the upper end of the bottom plate. An obliquely arranged screening plate is movably arranged in the shell, and the two ends of the screening plate are both rotatably connected to the shell. A feeding hopper is arranged at the higher end of thescreen plate and on the inner wall of the shell, buffer springs are welded on the two sides of the bottom end of the screening plate, and the bottom ends of the buffer springs are welded with supporting blocks. The supporting blocks are fixedly connected to the inner wall of the shell, a reciprocating push mechanism is connected to the screening plate, and a coarse particle collecting box is mounted at the lower end of the screening plate and on the outer side of the shell. According to the screening mechanism for coal, the screening plate is obliquely arranged, material blockage can be effectively prevented, and materials can slide to a low position for a high position; the springs are arranged at the bottom end of the screening plate and are matched with the reciprocating push mechanismfor use, the screening plate is made to shake through the elastic deformation of the springs, and therefore shock excitation for coal screening is improved.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to a screening mechanism for coal. Background technique [0002] Due to the development of coal slotting mechanization, the content of fine-grained coal in most mining areas has increased, and the smaller the particle size, the more gray it is. It is suitable to adopt the combined process of screening and gravity separation, that is, fine-grained coal is directly supplied to customers, and coarse-grained coal is selected and washed. Processing requires screening at this time. In the existing technology, especially the need for large-scale coal preparation plants and high-yield and high-efficiency needs, the processing capacity of the screening machine also needs to increase accordingly, resulting in the accumulation of materials during the screening process. Hole blocking phenomenon. Contents of the invention [0003] The purpose of the present invention is to solve the p...
