Intermittent rotating separation type drum screen for mining area of coal mine

Abstract

The invention discloses an intermittent rotating separation type drum screen for a mining area of a coal mine. The intermittent rotating separation type drum screen comprises a bottom plate, mounting plates, a supporting column, a roller, inner cylinders, separation plates, a driving gear, a driven gear and an intermittent driving device. The upper portion of the bottom plate is fixedly connected with a pair of the mounting plates which are arranged in a manner of being parallel to each other. After the roller rotates intermittently every time, a discharge outlet of a feed pipe exactly corresponds to the left ends of the inner cylinders, and raw materials are uniformly scattered in the different inner cylinders. For a traditional overall large drum screen, there still exist the problems that the screening efficiency is affected by too little raw materials and the screening quality is affected by too many raw materials. According to the intermittent rotating separation type drum screen, the raw materials are located in the different inner cylinders, so that the probability of the situation that due to too many raw materials, the raw materials are mutually buried and consequently the screening quality is difficult to improve is reduced. Therefore, the intermittent rotating separation type drum screen improves the screening quality and has good practical effects as well as guaranteeing the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to an intermittently rotating partitioned trommel screen for coal mining areas. Background technique [0002] In mineral processing equipment, trommel screen is a relatively commonly used one. In the screening process of mineral materials, traditional screening equipment such as fixed screen, roller screen and plane motion screen, etc., the working part of the fixed screen is fixed. The mineral materials are screened by sliding along the working surface, but the production efficiency of the fixed screen is low. Or the gaps between the plates pass through, but the large pieces of mineral materials are driven by the roller to move to one end but cannot be screened out from the end. The plane motion screen swings or vibrates in a plane. Due to the swing motion of the machine body, the screen surface The mineral material moves to the discharge end at a certain speed, and the m...

[0002] In mineral processing equipment, trommel screen is a relatively commonly used one. In the screening process of mineral materials, traditional screening equipment such as fixed screen, roller screen and plane motion screen, etc., the working part of the fixed screen is fixed. The mineral materials are screened by sliding along the working surface, but the production efficiency of the fixed screen is low. Or the gaps between the plates pass through, but the large pieces of mineral materials are driven by the roller to move to one end but cannot be screened out from the end. The plane motion screen swings or vibrates in a plane. Due to the swing motion of the machine body, the screen surface The mineral material moves to the discharge end at a certain speed, and the mineral material is screened at the same time, but the screening procedure is complicated

[0003] The traditional screening equipment has to go through screening and grading hidden in the process. There are many processes and the equipment occupies a large area, which is inconvenient and flexible to use. For the traditional overall large-scale drum screen, there are often too few raw materials that affect the screening efficiency and too much raw material. Multiple issues affecting screening quality
