Drum type gullet tooth screening and impurity removing equipment

Abstract

The invention discloses drum type gullet tooth screening and impurity removing equipment. The drum type gullet tooth screening and impurity removing equipment comprises a feeding hopper and a drum sieve, wherein the drum sieve comprises gullet tooth shafts; two ends of the gullet tooth shafts are arranged with a first sieve frame and a second sieve frame through sliding bearings in a matching way; pinions are additionally arranged at the left ends of the corresponding gullet tooth shafts; the pinions and an internal tooth gear are arranged in a meshing way; the internal tooth gear and the left part of an inner cavity of a first bearing frame are arranged in the matching way; the first bearing frame and a second bearing frame are fixedly connected with a support; the first sieve frame and the second sieve frame at two ends of the drum sieve are separately connected with the first bearing frame and the second bearing frame through rolling bearings; the right end of the drum sieve is connected with a bull gear; a motor is arranged at the upper end of the second bearing frame through a motor bracket; a motor gear is additionally arranged at the shaft end of the motor; and the motor gear and the bull gear are arranged in the meshing way. Compared with a traditional screening mechanism, the device disclosed by the invention adopts a drum type gullet tooth screening mechanism, so that the problem about blockage of screen cloth is effectively avoided; and meanwhile, the overhaul is facilitated.

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...

[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 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
