Description
Technical field
The present invention relates to a kind of filter, especially a kind of powdered resin precoat filter.
Background technology
Powdered resin precoat filter is that Powdered anion and cation exchange resin filtrate is covered on a kind of special porous pipe fitting, makes it form a thin layer, and as filter membrane, water enters in the pipe by filter membrane and hole by pipe fitting is outer, filters.Powdered resin precoat filter is after operation a period of time, and filter membrane needs to change, and carries out quick-fried film, backwash process.In quick-fried film, backwash process, generally adopt compressed air to enter the filter element center by the filter element lower end, the spent resin powder that lost efficacy is split away off together with adsorb impurity purge like the filter element blast with him.After the quick-fried film of air inlet, be right after water and carry out backwash.The backwash of entrance pressure contracting air is to utilize compressed air in short-term, the energy of outburst drives and carries out backwash at a high speed.Therefore, compressed air can enter the key that the filter element center becomes quick-fried film fast and stable.The general employing is filled with compressed-air actuated method in the middle of the prior art in the chamber of filter element lower end, and compressed air enters filter element by adapter.When being filled with liquid in the chamber of filter element lower end, enter rapidly filter element in order to make compressed air, the more logical compressed air of liquid of need at first draining has increased operation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of powdered resin precoat filter is provided, in quick-fried film backwash process, compressed air can fast and stable enters filter element.
According to technical scheme provided by the invention, described powdered resin precoat filter, comprise cylindrical shell, the top of cylindrical shell is fixedly connected with roof manhole, water feed apparatus and outlet pipe are installed in bottom at cylindrical shell, described water feed apparatus comprises the water inlet pipe that is connected to cylinder body bottom, water inlet pipe is fixed in the cylindrical shell by porous arc plate, be tightly connected between the madial wall of porous arc plate and cylindrical shell, cylindrical shell is separated into filter element chamber and inflating cells, water inlet one end of water inlet pipe stretches out the cylindrical shell outside, and water outlet one end is arranged in the filter element chamber; Be provided with several through holes at described porous arc plate, the filter element junction block is set in through hole; Filter element is installed in inside at described cylindrical shell, the upper end of filter element is fixed in the cylindrical shell by fixed head, the lower end of filter element is connected with corresponding filter element junction block respectively, and the lower end of filter element junction block is arranged in the inflating cells, is provided with equally distributed a plurality of air inlet pipe at the sidewall of inflating cells; Feature is: described filter element junction block evenly distributes around the circumferencial direction of water inlet pipe, is provided with pore on one or more filter element junction blocks of outmost turns, and pore is arranged on the below of porous arc plate.
Above the port of water outlet one end of described water inlet pipe, be provided with water retaining disk.
Be provided with a plurality of visors at described cylindrical shell.
Powdered resin precoat filter of the present invention can guarantee the filter element that enters of compressed air fast and stable in quick-fried film backwash process.
