Abstract

The invention relates to a large central drain pipe structure in cloth filter equipment in a sewage treatment plant. The large central drain pipe structure in the cloth filter equipment comprises drain holes of central drain pipes, and drain holes of a filter frame; the cross sections of the drain holes of the central drain pipes are shaped like a convex polygon; water hole drain holes are formed in each panel of the drain holes of the central drain pipe; drain holes of a connecting plate are fixedly formed in the inner surface of each panel of the drain holes of the central drain pipes at two sides of the water hole drain holes; the length direction of the drain holes of the connecting plate is consistent with the drain holes of the central drain pipes; and the drain holes of the filter frame are fixedly formed in the outer surface of each panel of the drain holes of the central drain pipes. The central drain pipe provided by the invention has high bending-resistant strength, and has the advantages of large cross section area under the condition that the same filtration areas of the central drain pipes are ensured; and the large central drain pipe structure has the advantages of convenience in manufacturing and the like.

Description

Filtering cloth filtering pool equipment center drain structure

Technical field

The present invention relates to a kind ofly for the medium-and-large-sized central drainage pipe structure of sewage treatment plant's filtering cloth filtering pool equipment, belong to technical field of sewage treatment equipment.

Background technology

At present, the structure of the general filtering cloth filtering pool equipment center drainpipe that uses as shown in Figure 1 and Figure 2: the six decile filter discs that are equipped with filter cloth are connected to each face of six side's connectors by double threaded screw.Each face of six side's connectors is communicated with central drainage pipe by mozzle.Discharged outside the filter tank by central tube by the sewage of every filter-cloth filtering like this.The defective of this structure mainly contain following some: 1, in the fixed situation of filter disc external diameter, for increasing to greatest extent the filter area of filter disc, make the sectional dimension of central drainage pipe less, cause filtering rear water impeded drainage, affect the rate of filtration of equipment, treating capacity reduces; Because the central drainage pipe sectional dimension diminishes, the Whole Equipment bending strength reduces simultaneously; 2, increase by six side's connector and mozzles, the processing technology of equipment is complicated, and manufacturing cost increases.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of bending strength high, in the situation that guarantee that identical filter area has the filtering cloth filtering pool equipment center drain structure of larger cross-sectional area.

according to technical scheme provided by the invention, described filtering cloth filtering pool equipment center drain structure, comprise central drainage pipe osculum and filter frame osculum, the shape of cross section of central drainage pipe osculum is convex polygon, offer the water hole osculum on each panel of central drainage pipe osculum, be fixed with the connecting plate osculum on each panel inner surface of the central drainage pipe osculum of osculum both sides, water hole, the length direction of connecting plate osculum is consistent with the central drainage pipe osculum, be fixed with described filter frame osculum on each panel outer surface of central drainage pipe osculum.

The shape of cross section of described central drainage pipe osculum is regular hexagon.Also be provided with the studs osculum, the studs osculum passes the connecting plate osculum and with the corresponding panel of central drainage pipe osculum, the filter frame osculum is fixed on the corresponding panel outer surface of central drainage pipe osculum.

Central drainage pipe in the present invention has higher bending strength, in the situation that guarantee the identical filter area of central drainage pipe, have larger cross-sectional area, and the present invention has the advantages such as easy to make.

The specific embodiment

The invention will be further described below in conjunction with specific embodiment.

This filtering cloth filtering pool equipment center drain structure, comprise central drainage pipe 1 and filter frame 2, the shape of cross section of central drainage pipe 1 is convex polygon, offer osculum 3 on each panel of central drainage pipe 1, be fixed with connecting plate 4 on each panel inner surface of the central drainage pipe 1 of osculum 3 both sides, the length direction of connecting plate 4 is consistent with central drainage pipe 1, is fixed with described filter frame 2 on each panel outer surface of central drainage pipe 1.

The shape of cross section of described central drainage pipe 1 is regular hexagon.

Also be provided with studs 5, studs 5 passes connecting plate 4 and with the corresponding panel of central drainage pipe 1, filter frame 2 is fixed on the corresponding panel outer surface of central drainage pipe 1.

In the present invention, central drainage pipe 1 is selected easily six square steel of buying of market, the kidney-shaped osculum 3 that each face of six square steel is reserved and filter frame 2 communicates.Elongated connecting plate 4 by bolted in each face of six square steel bottom.Studs 5 passes six each panel of square steel and connecting plate 4 is fixed on filter frame 2 in each face of six square steel by nut and packing ring, in the situation that constant central drainage pipe 1 area of section of filter area is maximum, water outlet is unimpeded like this.Elongated connecting plate 4 namely fixedly filter frame 2 increased again the bending strength of central drainage pipe 1.
