Abstract
The invention discloses high-turbidity sewage filtration equipment, which comprises a cylinder. The lower end of the cylinder is provided with a supporting board; a water generation chamber is formed between a cylinder base and the supporting board and provided with a water outlet; a water inlet is formed on the cylinder; a plurality of hollow filter elements are arranged on the supporting board; the supporting board is provided with water discharge holes through which hollow parts of the filter elements are communicated with the water generation chamber; a hollow filter element supporting tube is arranged in each filter element; the side of the filter element supporting tube is provided with a plurality of permeable holes of the filter element; and a filter element cap is arranged on each filter element. The high-turbidity sewage filtration equipment has the advantage that: when a large number of suspended substances are attached to the surface of each filter element and the filter capacity of the filter elements is weakened or lost, the filter element supporting tubes can prevent the filter elements can be prevented from being deformed or burst caused by high inside and outside pressure difference.
Description
Technical field
The present invention relates to a kind of sewage filtration equipment, especially relate to a kind of high-turbidity sewage filtration equipment.
Background technology
A kind of high-turbidity sewage filtration equipment is arranged, and as shown in Figure 1, it comprises cylindrical shell, is provided with tens filter cores to hundreds of root hollow in the cylindrical shell, and the sewage that gets into cylindrical shell can be held back a large amount of suspended particulate substances in the sewage through behind the filter element filtering, reduces the sewage turbidity.The cylindrical shell lower end is provided with the gripper shoe that fixing filter core is used, and gripper shoe is provided with apopore, supplies the water behind the filter element filtering to discharge.For the filter core upper end of One's name is legion is fixed, the top of filter core is provided with upper cover plate, with the filter core pressing plate upper cover plate is fixed on the filter core then.There is following shortcoming in this kind treatment facility: the filter core of hollow is processed by the plastics of porous, and its material is softer, because long period of soaking is in the sewage of high turbidity; Its surface can be attached with a large amount of suspensions; Cause sewage in the cylindrical shell can't enter into the hollow of filter core, and the water pump of import department can form a pressure differential always at pump water between filter core outside and the inside; The continuous increase of pressure differential finally can cause the filter core torsional deformation; Cause the slit occurring between upper cover plate and the filter core upper end, thereby the suspension in the sewage is entered into from the slit in the filter core, the sewage water filtration effect weakens greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-turbidity sewage filtration equipment of good purification.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of high-turbidity sewage filtration equipment, comprise cylindrical shell, and described cylindrical shell lower end is provided with gripper shoe; Form a product hydroecium between described cylindrical shell base and the described gripper shoe; Described product hydroecium is provided with delivery port, on the described cylindrical shell water inlet is set, and described gripper shoe is provided with the filter core of many hollows; Be provided with on the gripper shoe with the hollow of filter core with produce the drainage hole that hydroecium is communicated with; It is characterized in that being provided with in the described filter core filter core stay pipe of hollow, the sidepiece of described filter core stay pipe is provided with a plurality of filter core permeable holes, is set with the filter core block on the described filter core.
Be set with the pipe lid on the described filter core stay pipe, described pipe covers and is set with screw rod, and described filter core block is enclosed within on the described screw rod, and described filter core is blocked a shot with fixed by nut on described filter core.The setting of pipe lid can prevent that raw water from getting into from filter core stay pipe upper end.
Described filter core comprises skeleton and polypropylene layer, and described polypropylene layer is positioned at outside the described skeleton, a plurality of treatment holes that distributing on the described skeleton, and the outer surface of filter core stay pipe abuts against with the inner surface of described skeleton.The setting of skeleton can be strengthened the entire compression property of filter core, and the outer surface of filter core stay pipe abuts against with the inner surface of skeleton, can strengthen the crushing resistance of filter core better.
Be set with sealing ring on the drainage hole of described gripper shoe, described sealing ring inserts the polypropylene layer lower end of described filter core.Sealing ring inserts polypropylene layer lower end, prevents that raw water from getting into from the lower end and the slit between the gripper shoe of filter core.
The height of described filter core stay pipe is lower than the height of described filter core, and the lower end of filter core block has an annular protrusion, and described annular protrusion is positioned at described filter core stay pipe upper end.Annular protrusion is further strengthened the sealing of filter core block.
Described cylindrical shell open upper end, described cylindrical shell upper end is provided with upper cover, and described upper cover is provided with air bleeding valve.Upper cover can be opened when renew cartridge more, and the gas that air bleeding valve is detained in can expelling tube improves the contact area of filter core and sewage.
Described sealing ring is welded on the described gripper shoe, and described filter core stay pipe reaches in the drainage hole, and described filter core stay pipe is welded on the described gripper shoe.
Compared with prior art; The surface of filter core the invention has the advantages that after can be attached with a large amount of suspensions; The filter element filtering ability weakens or when losing; The setting of filter core stay pipe can prevent the distortion that filter core causes because of inside and outside high pressure differential or break, and has improved the service life of filter core, has saved more required material and the cost of labor of renew cartridge.
All filter core upper ends are fixed with a upper cover plate simultaneously in the traditional device; Because filter core One's name is legion; In installation process, be difficult to make all filter cores to become plumbness fully; The height that therefore can occur inevitably between the filter core is inconsistent, will cause phenomenon poorly sealed between part filter core and the upper cover plate like this.Each filter core upper end among the present invention all is provided with the filter core block, has solved the problem of individual filter core upper end water inlet well.
