Abstract
The utility model discloses a backwashing system of a filter. The backwashing system comprises a tank, and is characterized in that an exhaust valve is arranged at the top part of the tank; the top of the tank is connected with a main water inlet orifice by a pipe; a main water outlet orifice is arranged at the lower part of one side of the tank; a pneumatic clamp butterfly valve is arranged on the pipe along the main water inlet orifice; and another pneumatic clamp butterfly valve is arranged on a pipe along the main water outlet orifice. A backwashing water pump and compressed air are omitted from the backwashing system. The backwashing system of the filter has three backwashing modes which can be selected as needed, and has the advantages of high backwashing efficiency, short backwashing time, capability of saving water resource, and the like.
Description
Technical field
The utility model relates to a kind of backwashing system, specifically a kind of filter backwash system.
Background technology
In water treatment system, filter is as the equipment of the impurity such as removal suspension.Existing pressure type filter plant is in water treatment procedure, filtrate needs regular backwash, the pressure that the backwash flow is large and need are certain, therefore, system need arrange special-purpose backwash water pump, need compressed air, the backwash water source of this type of filter adopts fresh water source or filter water outlet, has increased the use rate of fresh water.
The utility model content
The purpose of this utility model is to provide a kind of filter backwash system.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of filter backwash system, comprise tank body, it is characterized in that described tank body top is provided with air bleeding valve, described tank body top is connected with the water inlet manifold mouth by pipeline, one side lower part of described tank body is provided with total effluent pipe mouth, described pipeline along the water inlet manifold mouth is provided with pneumatic wafer type butterfly valve, and the pipeline of the total effluent pipe mouth in described edge is provided with pneumatic wafer type butterfly valve.
Be equipped with Pressure gauge on described water inlet manifold mouth and the total effluent pipe mouth, described Pressure gauge one end is provided with the instrument air entrance.
Described tank base is connected with blow-down pipe by pipeline, and described blow-down pipe connecting pipe is provided with the wafer type butterfly valve.
Also be connected with the backwash effluent pipe mouth on the described water inlet manifold mouth connecting pipe.
The beneficial effects of the utility model:
The utility model backwash efficient is high, and backwashing time is short, saving water resource during backwash.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Among the figure: 1, tank body, 2, air bleeding valve, 3, Pressure gauge, 4, pneumatic wafer type butterfly valve, 5, the wafer type butterfly valve, 6, water inlet manifold mouth, 7, total effluent pipe mouth, 8, the backwash effluent pipe mouth, 9, the instrument air entrance, 10, blow-down pipe, 11, pneumatic wafer type butterfly valve, 12, pipeline, 13, pipeline.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Such as Fig. 1 and Fig. 2.
A kind of filter backwash system, comprise tank body 1, it is characterized in that described tank body 1 top is provided with air bleeding valve 2, described tank body 1 top is connected with water inlet manifold mouth 6 by pipeline 12, one side lower part of described tank body 1 is provided with total effluent pipe mouth 7, described pipeline 12 along water inlet manifold mouth 6 is provided with pneumatic wafer type butterfly valve 4, and the pipeline of the total effluent pipe mouth 7 in described edge is provided with pneumatic wafer type butterfly valve 11.Be equipped with Pressure gauge 3 on described water inlet manifold mouth 6 and the total effluent pipe mouth 7, described Pressure gauge 3 one ends are provided with instrument air entrance 9.Described tank body 1 bottom is connected with blow-down pipe 10 by pipeline 13, and described blow-down pipe 10 connecting pipes 13 are provided with wafer type butterfly valve 5.Also be connected with backwash effluent pipe mouth 8 on described water inlet manifold mouth 6 connecting pipes 12.Be provided with wafer type butterfly valve 5 between water inlet manifold mouth 6 of the present utility model and the pneumatic wafer type butterfly valve 4, be provided with wafer type butterfly valve 5 between total effluent pipe mouth 7 and the pneumatic wafer type butterfly valve 11, can carry out manual backwashing by hand push button.
Filtration condition, former water is entered by water inlet manifold mouth 6, enter tank body through pneumatic wafer type butterfly valve 4, pneumatic wafer type butterfly valve 4 on the backwash this moment effluent pipe mouth 8 cuts out, pneumatic wafer type butterfly valve 11 on total effluent pipe mouth 7 is opened and is filtered, and the water after the filtration gathers by total effluent pipe mouth 7 outflows.
The backwash state, when system operation time or operation pressure reduction reach when setting value, system enters the backwash state.At first filter element begins backwash, closes wafer type Pneumatic butterfly valve 4 and wafer type Pneumatic butterfly valve 11, opens the pneumatic wafer type butterfly valve of backwash water outlet, high speed backwash filter unit, and the backwash water outlet is discharged by backwash effluent pipe mouth 8.About 90～180 seconds of filter element backwash (adjustable).Backwash has three kinds of modes: (1) is according to water-in and water-out pressure reduction automatic backwash (pressure reduction is adjustable); (2) according to filtration time automatic backwash (time is adjustable); (3) carry out manual backwashing by hand push button.The backwash cycle was controlled by the time of ever-increasing pressure differential and setting, and along with constantly gathering of impurity, the pressure loss constantly increases, and when pressure reduction is increased to a certain setting value or when reaching the time value of a certain setting, system will be converted to the backwash state automatically.Pressure (hydraulic) water oppositely enters tank body by outlet valve, and it is washed away, and the pollutant that dams is come off and discharges filtration system.After about 3 minutes of backwash duration, valve goes to filtration condition with system automatically.
