Abstract
The utility model provides a filter element of a disc type filter comprising a spring gland, a sealing end cover, a sealing base and four back-flushing hollow columns connected between the sealing end cover and the sealing base, wherein the back-flushing hollow column is provided with a plurality of nozzles and is composed of multiple sections; each section of the back-flushing hollow column is connected via bayonet type; the four back-flushing hollow columns on the same section are connected by column connecting reinforced ribs; and the filter element of disc type filter further comprises at least two connecting rods penetrating through the sealing end cover, the column connecting reinforced ribs and the sealing base in turn; two ends of the connecting rod are provided with screws and are tightly fit with the sealing end cover and the sealing base via nuts. The disc type filter element has long service life, simple manufacture and high utilization rate of production moulds, thereby reducing production cost, and meanwhile the back-flushing efficiency of the filter element of a filter is high, and water volume for flushing is saved.
Description
Technical field
The utility model discloses a kind of filter, particularly a kind of disc filter filter core that comprises housing and filter core.
Background technology
Full-automatic disc filter is quite general in the application of developed country, because of it can be worked accurately and stably under quite harsh service condition and seldom needs to safeguard the fields such as irrigation, wastewater treatment, regeneration effluent, municipal water supply, waterworks, big power station, chemical enterprise and case of emergency that are widely used in.Full-automatic disc filter adopts modularized design, can carry out multiple being used in combination according to filter element quantity, and a backwash controller can be controlled the backwash process of one or more filter elements, to satisfy the actual needs of different application occasion.Disc filter is made up of filter housing and filter core; Filter housing is generally carbon steel plastic-coated, plastics, and shape is not limit.Filter core is shaped as hollow cylinder, and the annular plastics sheet that hollow cylinder is marked with micron order equilateral triangle groove by a lot of two sides is assembled on the center framework to be formed.The lamination that filter disc is compressed by spring and hydraulic pressure in each filter element forms does not have the filter screen that several impurity can't pass through.Traditional disc filter filter core is by spring capping, end cover, sealed base and be connected four hollow columns of backwash between end cover, the sealed base.The hollow column of backwash is four single monoblock types, and backwash column two ends are silk mouths, are connected moulding with end cover, sealed base silk mouth.The long-term processing of process is used and is found, traditional filter core working of plastics silk mouth ways of connecting, and service life is low; Because the disc filter filter core all is to work under the water under high pressure environment, therefore integrally-built service life and fastness are also lower simultaneously.
The utility model content
Goal of the invention: technical problem to be solved in the utility model is poor at disc type filter element fastness in the prior art, and the defective that service life is low provides a kind of well-set disc filter filter core.
Technical scheme: the utility model provides a kind of disc filter filter core, comprise spring capping, end cover, sealed base and be connected four hollow columns of backwash between end cover, the sealed base, the hollow column of described backwash is provided with plurality of nozzles, the hollow column of described backwash is by constituting more than two joints, and each saves the hollow column of backwash by bayonet coupling; Be provided with column between four hollow columns of backwash of each joint and connect reinforcement.This disc filter filter core also comprises the connecting rod more than two, and described connecting rod passes end cover successively, column connects reinforcement and sealed base; And the connecting rod two ends are provided with screw thread, and fit by nut and end cover and sealed base respectively, can strengthen whole fastness thus.
In the utility model, hollow column one end of described backwash is provided with recess, and the other end is provided with projection; Each saves between the hollow column of backwash and is bayonet coupling by described recess and protruding the cooperation.Can improve the precision of packaging efficiency, assembling thus, working strength is easy to remove and repair simultaneously.
In the utility model, in the utility model, the hollow column of described backwash engages with end cover and sealed base.
In the utility model, preferably, described connecting rod is four, can keep the whole steadily fixing of end cover, the hollow column of backwash and sealed base thus.
In the utility model, preferably, the nozzle of the hollow column of described backwash is the big divergence expression structure in the inboard little outside.Thus, the water under high pressure that ejects from the hollow column of backwash is dispersion shape, and the backwash area is bigger, better effects if.
In the utility model, preferably, the hollow column of described backwash is two joint or three joints.
In the utility model, preferably, be provided with the dowel stiffening ring between the described backwash column connection reinforcement, backwash column, connection reinforcement and dowel stiffening ring are the integrated through injection molding moulding.
In the utility model, preferably, described connecting rod is the stainless steel connecting rod.
Beneficial effect: disc filter filter core described in the utility model, long service life, production and processing is simple, the packaging efficiency height, thus reduced production cost, the backwash efficient height of while filter element, the water yield of the flushing of saving.
