Filtering tank capable of being easily cleaned and replacing filtering materials

Abstract

The invention discloses a filtering tank capable of being easily cleaned and replacing filtering materials. The filtering tank comprises a tank body, as well as a water inlet pipe and a water outlet pipe which are communicated with the inner part of the tank body, wherein the tank body is composed of an upper tank body and a lower tank body which are detachably connected; a sealing part is arranged on the connection part of the upper tank body and the lower tank body; the water inlet pipe is located on the lower part of the lower tank body and the water outlet pipe is located on the upper part of the upper tank body; the lower tank body is internally provided with a filler layer and a filtering net in sequence from top to bottom; the filtering net is located above the water inlet pipe; a dreg discharging opening is formed in the bottom of the tank body; valves are arranged on the water inlet pipe, the water outlet pipe and the dreg discharging opening. According to the filtering tank capable of being easily cleaned and replacing the filtering materials, liquid enters the tank body from the water inlet pipe and sequentially passes through the filtering net and the filler layer to be discharged from the water outlet pipe; the liquid is doubly filtered through the filtering net and the filler layer and the filtering effect is good; the tank body is composed of the upper tank body and the lower tank body which are detachably connected and the inner part of the tank body is convenient to detach and clean; the filler layer is also convenient to replace.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter tank which is easy to clean and replace filter materials. Background technique [0002] At present, for the purification of liquids containing sediments such as sediment, the filter tank is generally used for filtering. The filter tank is equipped with a filter screen. When the liquid to be filtered enters through its water inlet, the sediment and other sundries are removed It is trapped under the filter screen, while the clean liquid flows out from the upper outlet. Generally, there is a slag discharge port at the bottom of the filter tank, which can clean up part of the sediment, but it does not rule out the small volume of sediment passing through the filter screen and adhering to it. On the upper surface of the filter screen or in the mesh, in addition, relying on the filter screen alone for one layer of filtration, the effect is not obvious, so people use the filter material toge...

[0002] At present, for the purification of liquids containing sediments such as sediment, the filter tank is generally used for filtering. The filter tank is equipped with a filter screen. When the liquid to be filtered enters through its water inlet, the sediment and other sundries are removed It is trapped under the filter screen, while the clean liquid flows out from the upper outlet. Generally, there is a slag discharge port at the bottom of the filter tank, which can clean up part of the sediment, but it does not rule out the small volume of sediment passing through the filter screen and adhering to it. On the upper surface of the filter screen or in the mesh, in addition, relying on the filter screen alone for one layer of filtration, the effect is not obvious, so people use the filter material together, but because the current filter tank is a whole, it cannot be disassembled, and the addition of filter material It is very troublesome to clean and remove, and the inside of the filter tank and the filter screen cannot be cleaned thoroughly, which affects the filtering effect
