water filtration equipment

Abstract

The present invention provides a water filtration device, which includes: a filter tank 100 with an upper opening and a partition wall 110 inside, more than one filter plate 200, a filter layer 400, a plurality of air injection pipes p, a maintenance hole 500 and a water storage The filter plate 200 is located above the filter tank 100 and the partition wall 110 to close the filter tank 100; the air injection pipe p is located below the filter plate 200; the maintenance hole 500 is located in the The middle part of the filter plate 200 ; the filter layer 400 is located above the filter plate 200 ; the water storage part is located above the filter layer 400 and the filter plate 200 . The water filtering equipment provided by the present invention avoids stagnant water areas during backwashing, improves the quality of purified water and enhances the trust of consumers. The filter plate is easy to install, can not only improve work efficiency but also shorten construction period and save installation cost.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a filter device for rainwater or river water. Background technique [0002] As we all know, water treatment equipment is often used to purify raw water such as rainwater or river water to produce drinking water or clean water that can be discharged. In the past, there have been various forms of water purification treatment methods, such as figure 1 As shown, the filter tank is used as water filtration equipment for purifying and filtering raw water such as rainwater or river water. It includes room-shaped buildings 1 arranged on both sides. From bottom to top, there are water collection channel 2, lower water collection device, gravel layer 30 and filter material layer 40, etc. The water collection channels 2 on both sides converge in the central water purification channel 3 and lead to the water purification tank. [0003] The filter material layer 40 plays a purifying role in filter...

Problems solved by technology

[0009] But above-mentioned filter plate 60 is because its area is too small, will cover filter tank 100 and need more filter plate 60, thereby has reduced the efficiency and productivity of installation operation, and this is the fundamental problem of existence; 62 and gasket 64 to fix the filter plate 60 are easy to loosen due to high pressure during backwashing, and the loosening of the filter plate 60 also occurs frequently, which not only fails to achieve the safety of water purification, but also increases reinstallation and repair. Plate 60; From a structural point of view, there is a gap between the filter plate 60 and the filter plate 60, causing the distance L' between the filter tubes 68 to not meet the standard value, unable to form smooth washing and resulting in stagnant water area, not only can not improve the efficiency of water purification, but also greatly reduce the trust of consumers
