Description

The Multifunction water filter

Technical field

The utility model relates to a kind of equipment for filtering water, particularly a kind of Multifunction water filter that is applied in waterpower, thermal power plant and other industry water intakings, water system.

Background technology

The filter plant of water for industrial use mainly contains two big kinds: a kind of is filtrate formula filtering tank, and its work principle of filter is to fill cobble, anthracite and quartz sand as filtrate in jar, and recirculated water is carried out physical filtering and chemisorbed filtration.Its shortcoming is that volume is big, and flow is little, and filtrate must regularly be changed, and the cost of use height can't be realized backwash truly, and filtrate is leaked in race easily, makes pipeline blockage; Another is as filter with metal establishment net or whole punching type metal otter board, be characterized in water quality is carried out physical filtering, the foreign material of restriction certain diameter pass through equipment for filtering water, it is little that more preceding a kind of filter has a volume, the characteristics that flow is big, but this type of water filter of domestic present production, because the irrationality of its structure, some equipment can not effectively be removed water float thing or silt and other sediment, some equipment then can not be removed dirt and the impurity on the filter screen effectively, and its serviceability always can not satisfy customer requirements well.

Summary of the invention

The utility model provides a kind of Multifunction water filter that can effectively discharge floating thing and deposit and remove dirt on the screen pack automatically for overcoming above-mentioned defective

A kind of Multifunction water filter, comprise the water filter tank body, be located at the drive unit of the outer crown center of water filter tank body, filter screen, water inlet pipe and outlet pipe, it is characterized in that described water filter tank body is by last, following chamber dividing plate is divided into upper cavity, drainage cavity and lower chamber three parts, in the drainage cavity, annular filter screen is installed, on the rotating shaft of the drive unit in the drainage cavity hollow blade is installed, its openend contacts with filter screen, the hollow shaft of bottom for communicating with the blade cavity of the rotating shaft of described hollow blade is installed, its lower end communicates with the decontamination orifice that is installed on the lower chamber sidewall, at above-mentioned lower chamber, be separately installed with water inlet pipe and outlet pipe on the drainage cavity wall, also be separately installed with at above-mentioned upper cavity sidewall and lower chamber bottom, the down blow pipe.

The contacted openend of above-mentioned hollow blade and filter screen is equipped with the brush of removing contamination.

Above-mentioned hollow blade top all is equipped with the rocking arm of setting upright that is connected with rotating shaft.

Described drive unit is a motor.

Described drive unit is a rocking handle.

Can regularly open during the utility model execute-in-place that scum valve, down blow valve or rotation hollow blade carry out clearly, blowdown according to the water quality condition of locality and water intaking condition pointedly, can effectively remove floating thing and deposit in the water, again can the dirt removal on the filter screen is clean, has safe, efficient, energy-conservation, scrubbing technical characterstic completely, have the function that clean water is provided continuously, reliably to watering equipment, be particularly suitable for the applications of open type water intakings such as river, river, lake, sea.
