Equidistributed Angle Hydraulic Cylinder Motor with Mine Backwash Filter

Abstract

The invention belongs to the field of mining hydraulic motors, and in particular discloses a hydraulic cylinder motor with an equal distribution angle and a backwash filter for mining; the technical problem to be solved is to provide a motor with simple structure, convenient operation, high safety factor, and Equidistributed angle hydraulic cylinder motor with mining backwash filter that has a long service life and can effectively reduce the accident rate in coal mines; the technical solution adopted: includes an oil tank, a filter device, an oil pump and a hydraulic cylinder motor, the supply of the oil tank The oil port is connected to the oil inlet port of the oil pump through a filter device, and the oil outlet port of the oil pump is connected to the oil return port of the oil tank through a hydraulic cylinder motor, which converts the horizontal reciprocating motion of the hydraulic cylinder into the crankshaft Rotary movement, the underground emulsion filter can provide different filtration accuracy, to ensure the clean emulsion provided to the hydraulic cylinder of the hydraulic cylinder motor, and to improve the service life of the hydraulic cylinder motor.

Description

technical field [0001] The invention belongs to the field of mining hydraulic motors, and in particular relates to a hydraulic cylinder motor with equal distribution angles and a backwashing filter for mining, which is mainly used in coal mining machines, scraper conveyors, traction locomotives and cranes in coal mining working faces. Wait for the power input. Background technique [0002] The coal industry is the pillar industry of our country, and the safety in coal mining is the top priority. Because gas often exists underground in coal mines, the main components of gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, and trace amounts inert gases such as helium and argon. Under standard conditions, methane to butane exists as a gas, and above pentane as a liquid. In case of an open flame, it can burn, and a "gas"...

AI Technical Summary

Problems solved by technology

Diesel engines need to consume a lot of diesel oil during the working process, and they emit a lot of high-temperature hot gas, which poses a safety hazard

[0007] The above coal mine machinery mainly uses traditional motors or diesel engines for power input. This power input method is not suitable for coal mine machinery and equipment, and there will be great safety hazards in the process of using coal mine equipment. The safety factor is high, so the existing power input equipment has seriously restricted the development of coal mine underground equipment

[0008] In addition, at present, the high-pressure emulsion in underground coal mines needs to be filtered and then recycled. Generally, it is filtered by a filter. Due to the harsh environment in the mine, a lot of impurities will accumulate on the filter after a period of use, and these impurities will affect the performance of the filter element. Filtration speed and filtration efficiency, therefore, the filter element needs to be cleaned in time

At present, the filter element needs to be removed and cleaned, which requires the machine to be shut down to replace the filter screen, which affects normal production, and at the same time, the cost is high and the replacement time is long
