Novel environment-friendly pulverized coal processing and grinding equipment

Abstract

The invention relates to the technical field of environment-friendly pulverized coal processing, and particularly discloses novel environment-friendly pulverized coal processing and grinding equipment. The novel environment-friendly pulverized coal processing and grinding equipment comprises a base, a feeding hopper, a driving part and a rotating shaft, wherein a barrel body is fixedly installed on the base, the feeding hopper fixedly communicates with the center of the top of the barrel body, the driving part is installed in the center position of the upper part of the feeding hopper througha connecting rod, the rotating shaft is rotatably arranged inside the feeding hopper and the barrel body in a penetrating mode, an inner grinding layer is arranged at the inner bottom of the feeding hopper, a grinding roller is coaxially and fixedly connected to the position, on the rotating shaft, of the inner bottom of the feeding hopper, a lifting sleeve is arranged on the rotating shaft in a liftable and nested mode, a sieve plate is coaxially and fixedly connected to the outer side wall of the lifting sleeve, balls are rotatably arranged at the bottom of the lifting sleeve, a protruding block is fixedly arranged at the corresponding position of the upper surface of a supporting frame, a grinding ring is fixedly arranged on the outer side wall of the sieve plate, and a grinding sleeveis fixedly arranged on the outer side of the grinding ring and the inner wall of the barrel body. The novel environment-friendly pulverized coal processing and grinding equipment has the advantages ofbeing simple in structure, convenient to operate, sufficient in grinding, low in production cost and convenient to popularize and implement.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly pulverized coal processing, in particular to a novel environmentally friendly pulverized coal processing and grinding equipment. Background technique [0002] Coal powder is a kind of coal product made of washed coal, coking coal, etc. after screening, drying and grinding. It is mainly used for the molding of green sand in blast furnace smelting and casting. Coal powder is added to green sand for cast iron to prevent Sand sticking defects on the surface can improve the surface finish of castings, reduce sand inclusion defects, improve the collapse function of molding sand, and effectively prevent subcutaneous pores for wet ductile iron parts. The following problems exist in the prior art: in the processing and production of environmentally friendly coal powder, grinding is an important process. [0003] The existing patent discloses a pulverized coal grinding device, which includ...
