Positive pressure air pipeline drainage and rust scale discharging device

Abstract

The invention provides a positive pressure air pipeline drainage and rust scale discharging device which comprises a tank body, a positive pressure air inlet, a positive pressure air outlet, a drain outlet formed in the lower portion of the tank body, a drain valve arranged on the drain outlet, and a control device used for controlling the drain valve to be opened and closed according to water height in the tank body. The positive pressure air inlet and the positive pressure air outlet are formed in the upper portion of the side wall of the tank body. A baffle is arranged in the tank body, located between the positive pressure air inlet and the positive pressure air outlet, and close to the positive pressure air inlet. The baffle is used for blocking water and rust scale brought by positive air which enters the tank body from the positive pressure air inlet and enabling the water and rust scale to fall down onto the bottom of the tank body. Under the blocking action of the baffle on positive pressure air, the water and rust scale brought by positive air fall down onto the bottom of the tank body under the action of gravity of the water and rust scale, so that clean water and rust scale can be better separated, with the continuous elevation of the water surface, the control device can control actions of the drain valve to open the drain outlet, automatic drainage and rust scale discharging is achieved, and safe operation of a positive pressure air system can be guaranteed.

Description

technical field [0001] The invention relates to mechanical equipment technology, in particular to a water discharge and scale discharge device for a positive pressure air pipeline. Background technique [0002] At present, as the depth of mine mining continues to increase, a large number of positive pressure air pipelines need to be invested. The positive pressure air enters the underground through the positive pressure air pipeline, and the temperature of the positive pressure air gradually decreases with the continuous extension of the positive pressure air pipeline, causing the water vapor in the positive pressure air gas to condense on the inner wall of the positive pressure air pipeline Form water droplets, and form water accumulation areas at the corners or low-lying places of the positive pressure air pipeline, and the positive pressure air pipeline is easy to enter water, and there will be rust in the positive pressure air pipeline, the positive pressure air pipeline...
