Liquid filtering device for inlet of water pump of washing tower

Abstract

The invention discloses a liquid filtering device for an inlet of a water pump of a washing tower. The liquid filtering device comprises an FRP (fiber reinforced plastic) water tank provided with a cover plate, wherein the two ends of the FRP water tank are respectively connected with an inlet flange and an outlet flange, a filter plate which is vertical to a base plate of the FRP water tank is arranged inside the FRP water tank, and an FRP side plate is coated on outer surface of the filter plate. Liquid in a water tank of the washing tower enters into the FRP water tank by virtue of the inlet flange to be filtered, and the liquid enters into the water pump by virtue of the outlet flange after filtering is completed. According to the invention, before the water pump is arranged, the liquid which can not be filtered by a filter screen in the water tank of the washing tower is filtered, and double filtration effect on internal circulating liquid is realized; a placing position of the liquid filtering device is lower than the water tank of the washing tower, thus impurities can be conveniently precipitated; and an independent filter plate is arranged inside the liquid filtering device, thus precipitate can be disposed at any time by closing a switching valve as required.

Description

technical field [0001] The invention relates to a liquid filter device for a water pump inlet of a washing tower, and belongs to the technical field of filter devices. Background technique [0002] In the liquid circulation system of the scrubber, the liquid in the water tank is pumped into the reaction kettle for subsequent treatment. The original liquid in the water tank has impurities, and generally cannot pass through the water pump directly, so as not to cause blockage of the water pump. Filtration equipment is a common device , the main function is to filter impurities in the liquid that block the normal operation of the system, and prevent impurities from affecting the concentration of the liquid. At present, the more common form is to set a movable double-layer filter plate inside the water tank to intercept impurities in the flowing liquid, so as to maintain the cleanliness of the liquid transferred to the system. However, when there are impurities in the liquid th...

AI Technical Summary

Problems solved by technology

However, when there are impurities in the liquid that the filter plate provided in the water tank cannot pass through, it cannot be filtered and enters the water pump. After entering the water pump, the first aid method usually adopted is to set a Y-type filter commonly used at present, but this filter Not only the cost is high, but also the filtering effect is not good
