The structure of existing filtering ponds can spring back over the water in the water inlet pipe problem in the blowdown district in the recoil process.
The utility model content
The technical problems to be solved in the utility model is: carrying when the backwash at existing filter tank, water enters the disadvantage of water down.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of antifreeze filtering ponds, have two cylindrical shells, connect by communicating pipe between two cylindrical shells, be arranged on the middle part of cylinder body outer wall communicating pipe, be used for the hydraulic pressure between two cylindrical shells of balance communicating pipe.Be provided with soil chamber in the cylindrical shell, water-purifying cavity and adapter cavity, soil chamber, water-purifying cavity is separated by filter course and adapter cavity, soil chamber is in water-purifying cavity, the delivery port of soil chamber is in filter course, the water inlet of water-purifying cavity adapter cavity in filter course is arranged on the bottom of cylindrical shell, be outside equipped with water feed apparatus at cylindrical shell, water feed apparatus has a house steward, both sides house steward are connected with outlet pipe, on outlet pipe, be connected with water inlet pipe, pipeline between house steward and the water inlet pipe is provided with control valve, and water inlet pipe is provided with control valve, and the soil chamber in the outlet pipe of water feed apparatus and the cylindrical shell is connected.
Be provided with blow-off pipe at adapter cavity in the utility model, blow-off pipe is provided with control valve.
In the bottom of filter course resistance is installed in the utility model and filters cap.
The beneficial effects of the utility model are, of the present utility modelly self realize antifreeze: be interconnected between two filter tanks, the water between the filter tank circulates mutually, therefore utilizes the heat that filters circulating water can realize that self is antifreeze; Designs simplification, reliable: back with water inlet line and backwash water pipeline unite two into one, and only need 2 valves to automatically switch and just can realize filtering and backwash; Water saving: its water inlet in backwash process of traditional filter tank does not stop, but along with backwash water is drained, this filter tank is to cut off water inlet when backwash.
