Explosion-proof screw supercharger under coal mine

Abstract

The invention discloses an explosion-proof screw supercharger under a coal mine. A bottom plate is included, and a first supporting plate is arranged on one side of the top of the bottom plate; the side, away from the first supporting plate, of the top of the bottom plate is provided with a second supporting plate; the side, close to the first supporting plate, of the second supporting plate is provided with a control plate; the side, close to the second supporting plate, of the first supporting plate is provided with an installing base; and a driving mechanism is arranged on the top of the installing base. According to the explosion-proof screw supercharger under the coal mine, by arranging the driving mechanism, a supercharging mechanism, a separating mechanism, a cooling mechanism and the control plate, the screw supercharger is simpler in structure, parts are more compact, and therefore cost is lowered; by arranging a filter, gas flow firstly passes through a filter to filter out water and rust; then gas recoil is prevented through an arranged non-return valve; and a gas inlet is additionally provided with a pneumatic ball valve for controlling gas inflow, and therefore the compression effect of the screw supercharger is better, and energy saving and environment protecting are facilitated.

Description

technical field [0001] The invention relates to the technical field of screw supercharging, in particular to an explosion-proof screw supercharging machine underground in a coal mine. Background technique [0002] The screw supercharger is actually an air compressor, which increases the air intake by rotating the screw to compress the air. However, the existing screw supercharger cannot meet the customer's demand for 16kg high-pressure air consumption, and the existing screw supercharger The structure of the machine is relatively complicated, and the parts are relatively loose, thereby increasing the cost, and the floor area is large, so that the use effect of the screw supercharger is not good, and the existing screw supercharger is easy to cause part of the gas to flow back when compressing the gas. Therefore, the compression effect of the screw supercharger is not good, and it is not conducive to energy saving and environmental protection. Contents of the invention [...
