Leakage-proof bolt assembly for fixing wear-resisting lining plate of ball mill

Abstract

The invention discloses a leakage-proof bolt assembly for fixing a wear-resisting lining plate of a ball mill. The leakage-proof bolt assembly comprises a ball mill shell and the lining plate, a screwrod is arranged on the ball mill shell and the lining plate in a penetrating mode, and the surface of the screw rod is sleeved with a nut in a threaded mode. According to the leakage-proof bolt assembly for fixing the wear-resisting lining plate of the ball mill, the leakage-proof bolt assembly for fixing the wear-resisting lining plate of the ball mill is fastened at a time, a certain pressure is always applied to an O-shaped ring through a gasket by utilizing the tension of the spring, and the O-shaped ring is always kept consistent in compression deformation rate under the condition that anut is coaxial with the wall of a ball mill cylinder, sealing is ensured, ore pulp leakage accidents are prevented from happening, and efficient and safe running of ball mill equipment is facilitated; and the leakage-proof bolt assembly is small and exquisite in design, light in weight, easy to carry, few in installation and disassembly accessories and capable of effectively reducing and completely eradicating ore pulp leakage, relieving the labor intensity of workers and increasing the field environment-friendly effect.

Description

technical field [0001] The invention relates to the technical field of mechanized production, in particular to an anti-leakage bolt assembly for fixing a wear-resistant liner of a ball mill. Background technique [0002] At present, the ball mill is an important equipment widely used in the mineral processing industry. It is one of the necessary large-scale and important mining machinery for the wet processing plant in the mining industry. The fine grinding process in the mineral processing industry and other grinding industries uses the rotation of the ball mill. After the steel balls and ore in the ball mill are brought to a certain height, free fall occurs, and the ore, the steel ball and the liner inside the ball mill cylinder collide with each other, and the ore is broken into fine particles. During the process, some of the liner plate fixing bolts may leak ore slurry. Since all ball mills are not fully considered in the design of the ball mill, the following types of f...

Problems solved by technology

[0005] 3. If the liner bolts of the ball mill are found to be loose during operation, it is necessary to stop the machine for fastening operations. If the fastening is not adopted, the liner bolts will loosen more seriously, and the pulp inside the ball mill will flow along the barrel. The gap between the bolt holes and the fixed bolts leaks and splashes out, which pollutes the environment around the grinding equipment and increases the labor intensity of the operators, which brings hidden dangers to safety production. Fasten the loose parts of the bolts during parking The process requires 2-3 workers to cooperate at the same time, and it takes about 30 minutes, which brings major safety hazards and economic losses to production and safety.

[0006] 4. After the bolt fastening process of the liner plate of the ball mill cylinder is completed, while the production is resumed, due to the sharp change of the ore feed rate, other auxiliary facilities in the whole process will have chain adverse reactions, seriously affecting the safety of production
