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

Abstract

The invention discloses an intermittently rotating partitioned trommel screen for coal mining areas, which includes a bottom plate, a mounting plate, a support column, a drum, an inner cylinder, a partition plate, a driving gear, a driven gear and an intermittent driving device. The upper part is fixedly connected with a pair of mounting plates arranged parallel to each other; after each intermittent rotation of the drum, the discharge port of the feeding pipe corresponds to the left end of the inner cylinder, and the raw materials are evenly dispersed into different inner cylinders. The overall large-scale drum screen often has the problem that too little raw material affects the screening efficiency and too much raw material affects the screening quality. The invention makes the raw materials be located in different inner cylinders, reducing the difficulty in improving the screening quality caused by the mutual burial of too many raw materials. Therefore, the present invention improves the screening quality while ensuring the screening efficiency, and has a good practical effect.

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
