Abstract

The utility model belongs to field of environmental engineering, and in particular to a kind of webbing filter screen, including the multiple twine units formed by lateral twine and longitudinal twine square crossing；The inside of each twine unit has been formed uniformly a plurality of hook twine, and the hook twine is parallel to the plane setting of the twine unit.The filter screen of the utility model is mounted on treatment tank water inlet, when sewage enters treatment tank, filter screen can by sewage webbing and polybag tangle, and filter this out.The utility model structure is simple, it is easy to use, can be widely applied to webbing in filter sewage.

Description

Webbing filter screen

Technical field

The utility model belongs to field of environmental engineering, and in particular to a kind of webbing filter screen.

Background technique

As people are to the pay attention to day by day of environmental issue, sewage treatment works are of increasing concern.Using sewage pumping When dirty water-sucking, the band-like cloth being frequently encountered in sewage, the rubbish such as polybag block water pump filter, or even in sewage pump leaf On piece winding, causes sewage pump can not work normally.

Currently, generally use latticed filter screen in the filter device for the treatment of tank and be filtered, this kind of filtering Net can effectively filter out the blocky foreign matter in sewage, and still, for such as cloth, this kind of foreign matter of polybag is extremely difficult to preferably Filter effect.

Utility model content

The purpose of the utility model is to overcome defects in the prior art, provide a kind of peritoneal dialysis sterilizing Cap.

The utility model to achieve the above object, using following technical scheme：

A kind of webbing filter screen, including the multiple twine lists formed by lateral twine and longitudinal twine square crossing Member；The inside of each twine unit is evenly distributed with a plurality of hook twine, and the hook twine is parallel to described The plane of twine unit is arranged.

For the twine unit at square, four sides of the square are uniformly arranged in the hook twine It goes up and extends internally.

The length of the hook twine is square the 1/3-1/2 of the length of side length.

The center of the side length of the square is arranged in the hook twine.

The hook twine is by being arranged at intervals on the lateral twine of the twine unit and the gap of longitudinal twine It is formed.

The lateral twine of each twine unit and the center of longitudinal twine is arranged in the gap.

Compared with prior art, the utility model has the beneficial effects that：

Webbing filter screen is due to using the completely new technical solution of the utility model, compared with prior art, this reality It is incomplete extension steel wire or cutting steel wire with novel hook twine, hook twine is vertically intersected in four side of grid Point can effectively tangle the band-like silk fabrics and polybag that pass through from grid, so that it be filtered out from sewage. The utility model structure is simple, it is easy to use, can be widely applied to webbing in filter sewage.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing The utility model is described in further detail with most preferred embodiment.

Fig. 1 shows a kind of webbing filter screen, more including being formed by lateral twine 1 and longitudinal 2 square crossing of twine A twine unit；The inside of each twine unit is evenly distributed with a plurality of hook twine 3, and the hook twine is parallel It is arranged in the plane of the twine unit.The twine unit is uniformly arranged at square, the hook twine On four sides of the square and extend internally.The length of the hook twine is square the 1/3- of the length of side length 1/2.The center of the side length of the square is arranged in the hook twine.

The utility model may be another situation, i.e., the hook twine is by being arranged at intervals on the twine The gap of the lateral twine of unit and longitudinal twine is formed.The transverse direction of each twine unit is arranged in the gap The center of twine and longitudinal twine.Dirt is tangled using the hook twine that the gap of lateral twine and longitudinal twine is formed Webbing in water.

The specific implementation process of the present embodiment：The mesh-density for selecting lateral twine and longitudinal twine to be formed is suitably multiple Steel wire grid unit is parallel to grid plan at four side midpoints of steel wire grid unit, welds and hangs perpendicular to grid sideline direction Hook twine, hook twine length are about the half of side length of element, can be in 1/3-1/2；The hook net of two opposite side of grid cell The neighbouring endpoint interval of silk is about the half of side length of element；Also it is original 2 times of steel wire that mesh-density, which can be selected, by steel wire In steel wire interruption be cut into it is imperfect cutting twine filter screen, two cutting steel wires adjacent to the distance between endpoint The about half of side length of element.The filter screen is mounted on treatment tank water inlet, when sewage enters treatment tank, Filter screen can by sewage webbing and polybag tangle, and filter this out.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
