Cooling device of diesel engine for coal mine

Abstract

The invention discloses a cooling device of a diesel engine for a coal mine, and relates to the technical field of diesel engine cooling. The cooling device comprises a box body and a partition plate fixed in the box body, one side of the box body is provided with a cover plate, and one side of the box body is fixedly provided with an air inlet mechanism; a wind power rotating mechanism is fixed to the side, close to the air outlet end of the air inlet mechanism, of the inner wall of the bottom of the box body, a filtering mechanism is installed in the box body, a reset cleaning mechanism is arranged on one side of the filtering mechanism, and an eccentric transmission mechanism is in transmission connection between the reset cleaning mechanism and the wind power rotating mechanism; a gas conveying mechanism communicating with an inner cavity in the left side of the box body is fixed to the top of the box body, and a heat exchange mechanism is fixedly connected to the gas outlet end of the gas conveying mechanism. The high-temperature gas near the diesel engine can drive the bristles to clean the surface of the filter screen cloth, the spiral blades can be driven to guide out impurities, and the impurities are prevented from being accumulated in the heat exchange bent pipe.

Description

technical field [0001] The invention relates to the technical field of diesel engine cooling, in particular to a cooling device for a coal mine diesel engine. Background technique [0002] Explosion-proof diesel engines for coal mines are Class I internal combustion engines suitable for tunnels in underground mining areas where methane and combustible dust exist. The cooling methods of diesel engines are divided into two categories: water cooling and air cooling. The heat is transferred out. The diesel engine of this cooling method is usually composed of a water pump, a cooling water tank, a thermostat, etc. Under the action of the water pump, the cooling water is sucked into the interior of the diesel engine and flows along a certain route to absorb and take away the heat generated by the parts. Keep the operating temperature of the diesel engine within a certain range. In some explosive environments, the exhaust gas of the diesel engine is also equipped with an exhaust co...

Problems solved by technology

[0005] The purpose of the present invention is to provide a cooling device for diesel engines used in coal mines to solve the problem that the prior art cannot filter the solid impurities contained in the exhaust gas. Some solid impurities will remain in the input pipe, which will affect the temperature transfer effect and cause cooling. Less effective technical issues
