A drum-type hook-tooth screening and impurity removal equipment

Abstract

The invention discloses a drum-type hook-tooth screening and impurity removal equipment, which includes a feed hopper and a drum screen. The drum screen includes a hook-tooth shaft. The two screen frames are installed together, and a pinion gear is installed on the left end of the hook tooth shaft. The pinion gear is installed in mesh with the internal gear, and the internal gear is installed in cooperation with the left part of the inner cavity of the first support frame. The first support frame The first screen frame and the second screen frame at both ends of the trommel are respectively connected to the first support frame and the second support frame through rolling bearings, and the right end of the trommel is connected to the large gear. The motor is installed on the upper end of the second supporting frame through the motor bracket, and the motor shaft end is equipped with a motor gear, and the motor gear is installed in mesh with the large gear. Network blockage problem, and easy maintenance.

Description

technical field [0001] The invention relates to the technical field of screening and impurity removal, in particular to a drum type hook teeth screening and impurity removal equipment. Background technique [0002] Most of the coal required for the existing coal furnace work is pulverized coal, but the mined raw coal is mostly in the form of lumps, and most of them are mixed with large particles and powder, which need to be pulverized by a pulverizer. The traditional operation mostly uses the mixture to be pulverized Machine crushing, because the coal powder inside the raw material seriously affects the crushing effect and crushing speed, so the screen is often used to separate the coal powder from the coal block before crushing, but the existing screening structure is relatively simple, and the screen mesh is relatively fixed. , It is easy to cause the blockage of the screen during screening, which seriously affects the screening effect, and the existing screening device ha...

The traditional operation mostly uses the mixture to be pulverized Machine crushing, because the coal powder inside the raw material seriously affects the crushing effect and crushing speed, so the screen is often used to separate the coal powder from the coal block before crushing, but the existing screening structure is relatively simple, and the screen mesh is relatively fixed. , it is easy to cause screen blockage during screening, which seriously affects the screening effect, and the existing screening devices are relatively complicated in structure, which is not easy to overhaul and seriously affects the work efficiency
