Lifting discharge filtering device for water tank

Abstract

The invention relates to a lifting discharge filtering device for a water tank, comprising a tubular housing, a top seat plate, and a lifting filter; the tubular housing is fixedly connected to the lower surface of the top seat plate, and the center of the top seat plate is provided with a water inlet; the lifting filter includes an inner barrel, an outer barrel and a primary filter plate, the primary filter plate is mounted in the inner barrel, the bottom of the outer barrel is connected to the lower portion of the inner barrel, a filter cavity is formed in the inner barrel, a cavity formed between the outer barrel and the inner barrel is an anti-overflow cavity, the lower portion of the inner barrel is provided with a through hole whereby the anti-overflow cavity is communicated with the filter cavity, a guide rail is mounted on the inner wall of the tubular housing and is fitted with a slider, the outer barrel is connected with the slider trough a mounting plate, and the slider is connected with a screw. The depth of the filter cavity can be vertically adjusted so as to adjust the volume of filtered impurities, impurity cleaning is facilitated, filtering effect is good, and water discharging is more environmentally friendly.

Description

technical field [0001] The invention relates to a lifting type water tank drainage filtering device, which belongs to the technical field of water treatment. Background technique [0002] In order to prevent solid debris from flowing into the water pipe, a filter cover is generally installed at the drain of the sink. For ordinary household water tanks, a simple filter cover can meet the requirements of use, but for industrial plants with large water consumption and many impurities Take the drainage tank as an example, the ordinary filter cover is not only easy to block, but also the filtering effect is not good, and the impurities often accumulate in the filter cover, which is difficult to clean. Contents of the invention [0003] The purpose of the present invention is to provide a lifting type water tank drainage filtering device, which has adjustable height, can change the amount of impurities that can be accommodated by height adjustment according to the amount of drai...
