Abstract
The utility model relates to a filter of water body, in particular to a pressure less type filter, comprising a shell, a water inlet, a water outlet, a drain outlet, the filter net of the shell and the filter net of the water outlet. The water inlet is arranged below one side wall of the shell, the water outlet is arranged above the other side wall of the shell, the drain outlet is arranged at the bottom of the shell, the filter net is fixed on the inner wall of the middle part of the shell, and the filter net of the water outlet is fixed on the end surface of the inner port of the water outlet. The utility model solves the problems existed in the prior art of that the operation in the using process is inconvenient, the service life is short, the filtering performance is bad, the water body purified and treated by the filters also has foreign matters, the people's using is influenced, etc. The utility model has the advantages that the filter performance is good, the purifying effect of the water body is good, the scope of application is wide, the operation is convenient and the service life is long. The pressure less type filter is specially adapted to the filtering requirements of the rain water recycle engineering and the system whose system pressure is low.
Description
Technical field
The utility model relates to a kind of filter of water body, does not especially have the pressure type filter.
Background technology
In the water body processing procedure, the general filter of following several forms that adopts is handled water body at present, y-type filter, dirt separator, automatic backpulsing filter, full-automatic filter etc., after using a period of time, y-type filter need be cut off the water after using a period of time, just can unpick and wash screen pack; Dirt separator, automatic backpulsing filter, full-automatic filter, do not need to cut off the water, do not need to unpick and wash filter screen, handle but need under certain hydraulic pressure, just can carry out blowdown, more than several filters all exist operation inconvenience in the use, service life is short, strainability is poor, through above-mentioned several filter cleaning treated water bodies, also can there be impurity etc., influence people and use.
The utility model content
In order to overcome the above-mentioned technological deficiency that prior art exists, the novel purpose of this use is to provide a kind of no pressure type filter, this product can carry out the filtration treatment of water body under passive state, its long service life, strainability is good, and water body purification is effective, and is applied widely, be specially adapted to the low system filtration requirement of rainwater recycling engineering and system pressure, easy to operate.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of no pressure type filter, comprise housing, water inlet, delivery port, sewage draining exit, housing screen pack and delivery port screen pack, described water inlet is arranged at the below of described housing one sidewall, described delivery port is arranged at the top of described another sidewall of housing, described sewage draining exit is arranged at described housing bottom, described housing screen pack is fixed on the inwall of described housing middle part, and described delivery port screen pack is fixed on the end face of inner port of described delivery port.
Described housing screen pack can be the screen pack of awl cartridge type or other any suitable patterns.
The tapering of described awl cartridge type screen pack can be the angle of 45 degree, 60 degree, 75 degree or other any suitable.
Operation principle: during work, water and liquid flow into from water inlet, side blow tapered barrel screen pack, filter for the first time, the impurity in the water is blocked in outside the filter screen, is deposited in the sewage draining exit top, water and liquid enter filter screen inside, behind the secondary filter through the delivery port screen pack, water flows out from delivery port, finishes the water body filtration, purification.
Adopt the beneficial effects of the utility model: owing to be fixed with awl cartridge type screen pack on the inwall of the described housing of this product middle part, be fixed with the delivery port screen pack on the end face of described delivery port inner port, therefore, its strainability is good, water body purification is effective, and is applied widely, is specially adapted to the low system filtration requirement of rainwater recycling engineering and system pressure, easy to operate, long service life.
