Description
Technical field
The utility model relates to a kind of filter, specifically is a kind of filter with backwashing function.
Background technology
Filtration belongs to indispensable processing means in the water purification process, is used for tackling the impurity of water, with purify water or protection system in the operate as normal of other equipment.Common well strainer is because of its good filtration effect, the little fields such as water source filtration, industrial cycle water system that are widely used in of resistance, but that its shortcoming is a pollutant holding capability is little, be subject to that dirt stops up, the cleaning complexity, must dismantle the cleaning that could realize to equipment to filtration fraction, and it is bigger influenced by human factor, makes the automaticity of whole system very low.Therefore, need a kind of filter that filtration fraction is cleaned of being easy to.
The utility model content
Primary and foremost purpose of the present utility model is to provide a kind of filter with backwashing function, and concrete scheme of the present utility model is as follows:
A kind of filter with backwashing function comprises tank body, filter courage, filter membrane; Described tank body is inner enclosed construction with cavity, and described tank body is provided with water inlet, and described water inlet is provided with inlet valve; Be provided with the filter courage in the cavity of described tank body, the sidewall and/or the bottom of described filter courage are provided with filtering holes, and described filter courage also is provided with delivery port, and described delivery port communicates with the outside of described tank body, and described delivery port is provided with flowing water Valve; The outer surface of described filter courage is coated with filter membrane.
Preferably, described inlet valve is connected with water pump.
Preferably, described delivery port is positioned at the top of described filter courage.
Preferably, be provided with dividing plate in the described tank body, described dividing plate is and is horizontally disposed with, and described filter courage is positioned at the below of described dividing plate; Described dividing plate is provided with connecting hole, and described filter courage communicates with the top of described dividing plate by connecting the aperture; Described delivery port is positioned at the top of described dividing plate.
Preferably, described connecting hole is more than 1 or 1, and described filter courage quantity is identical with described connecting hole quantity, and described filter courage communicates with the top of described dividing plate by connecting hole respectively.
In the above-mentioned utility model scheme, water to be filtered enters tank body through water inlet, filters by delivery port by filter membrane and discharges, and the solid particle in the water to be filtered (filter residue) is trapped within the outer surface of filter membrane, forms filter cake gradually.After filtering a period of time, when filter cake reached certain thickness, system entered recoil and washes down membrane stage, and filter cake is from the filter membrane sur-face peeling and be deposited to the bottom of tank body, and device reenters the filtration state.
The filter apparatus configuration with backwashing function that the utility model provides is simple, diverse in function; Can realize that low press filtration and filter area are wide, the adaptive temperature scope is big; And with low cost, volume is little, take up an area of to economize, long service life.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model embodiment 1 structural representation;
