Abstract

The utility model relates to a filter, in particular to a box-type multilayer filters which belongs to the technical field of environmental protection facilities. The box-type multilayer filter includes an inflow pipe, an outflow pipe, a filtering box body, a sealed cover plate, a filtering grid, a back flush pipe and a back flush discharge pipe. The inflow pipe and the outflow pipe is connected with the box body through a valve. The filtering grid is arranged in the box body by a plurality of layers. The back flush pipe is arranged under the lowest filtering grid through the valve. The back flush discharge pipes are respectively arranged under each of the filtering grids in the filtering box body. The sealed cover plate is arranged on the upper part of the filtering box body. The box-type multilayer filter has the advantages of greatly improving work efficiency of the filter, cleaning interception impurity conveniently and prolonging service life.

Description

The box type multilayer filter

Technical field

The utility model relates to a kind of filter, and particularly a kind of box type multilayer filter belongs to the environmental protection installation technical field.

Background technology

In industries such as chemical industry, medical medicine, oil, metallurgy, weaving, food, water treatments, in order to improve product purity, the safety of the auxiliary equipment such as protection compressor, pump, instrument need to be used filter usually.At present, existing y-type filter, such as Chinese patent (Granted publication number: CN202052408U, number of patent application: 201120129317.7) disclose " a kind of y-type filter ", it comprises Y type body and filter, Y type body is provided with three mouths of pipe, be respectively water inlet pipe mouth, effluent pipe mouth and end-of-the-pipe, filter is inserted in the end-of-the-pipe, and the water inlet of filter is positioned at after the water inlet pipe mouth, the delivery port of filter is positioned at before the effluent pipe mouth, and the end-of-the-pipe place is provided with the adapter with hollow cavity, is connected with blowoff valve on the adapter.But in modern factories, metering dosing pump range of application is more and more wider, as pump is last y-type filter is installed, but the concentration of part liquid is excessive or impurity too much just easily causes filter dirty stifled, cause the y-type filter cleaning frequent, cause filter screen shorter service life, and inconvenient operation, impact is produced.

Summary of the invention

For deficiency of the prior art, the utility model provides a kind of box type multilayer filter, has improved widely the operating efficiency of filter, is convenient to clear up impurity trapped, long service life.

According to design provided by the utility model, the box type multilayer filter comprises inlet channel, outlet conduit, filter box, seal cover board, screen pack, backwash pipeline and sewage backwash pipeline, it is characterized in that described inlet pipeline, outlet conduit are connected with filter box by valve, a screen pack minute multilayer places in the filter box, the backwash pipeline is arranged at the bottom screen pack bottom of filter box by valve, the sewage backwash device for cleaning pipeline is crossed the bottom that valve is arranged at respectively every layer of screen pack of filter box, and the filter box top is provided with seal cover board.

Described sewage backwash pipeline is interconnected, and each sewage backwash device for cleaning pipeline is crossed valve and fixed.

Described screen pack can be 2 ~ 5 layers.

The filter box of described box type multilayer filter is the PVC material.

The beneficial effects of the utility model:

1. the utility model box type multilayer filter screen pack divides two to be placed in the filter box, realizes multiple filtration, and retaining power is large, longevity of service.

2. the utility model box type multilayer filter is provided with backwash pipeline and sewage backwash pipeline, utilizes hydraulic pressure to realize on-line rinsing, is easy to cleaning, and is easy to maintenance.

3. the utility model box type multilayer filtration device structure is simple, and cost is low, is easy to promotion and implementation.

Description of drawings:

Fig. 1 is one of the utility model box type multilayer filter structure schematic representation;

Fig. 2 is two of the utility model box type multilayer filter structure schematic representation.

The specific embodiment:

Number in the figure 1 represents inlet pipeline, and label 2 represents the backwash blow-off line, label 3 seal cover boards, and label 4 filter boxs, label 5 represents screen pack, and label 6 represents outlet conduit, and label 7 represents the backwash pipeline, and label 8 represents valve.

Embodiment one, participate in Fig. 1, a kind of box type multilayer filter, comprise inlet channel 1, outlet conduit 6, filter box 4, seal cover board 3, screen pack 5, backwash pipeline 7 and sewage backwash pipeline 2, described inlet pipeline 1, outlet conduit 6 is connected with filter box 4 by valve 8, backwash pipeline 7 is arranged at bottom screen pack 5 bottoms of filter box 4 by valve 8, sewage backwash pipeline 2 is arranged at respectively the lower end of the screen pack 5 of filter box 4 by valve 8, be convenient to backwash, screen pack was placed in the filter box 4 in 5 minutes two, can realize multiple filtration, filter box 4 tops are provided with seal cover board 3, in case of necessity removable cleaning, the filter box of box type multilayer filter are the PVC material.

According to field condition, the box type multilayer filter is installed on the pump inlet pipeline, draw a fresh water pipeline and be installed on the import of backwash pipeline, sewage draining exit advances trench and gets final product.

Embodiment two, participate in Fig. 2, and the representative meaning that numbering and embodiment one are identical among the figure is identical, and something in common does not repeat, and difference is that described screen pack was placed in the filter box 4 in 5 minutes three.
