Abstract
The invention discloses a filter unit which has a large flow area, hardly winds or blocks and is easy to carry out blowback treatment. The filter comprises a tubular joint and a fence arranged at one end of the tubular joint and composed of grid bars; the tops of the grid bars gather inwardly. During utilization of the filter unit, the tubular joint is used to be connected with equipment or a pipeline matching with the tubular joint, and grid bars of the fence are used for intercepting solid waste in sewage. According to the invention, since the area of gaps formed by adjacent grid bars is far greater than the area of a mesh or a filtration pore, the flow area of the filter unit is effectively enlarged; furthermore, three dimensional gaps formed by the grid bars can effectively prevent dirt from blocking the filter unit and enable blowback treatment to be convenient.
Description
Technical field
The present invention relates to a kind of filter, especially a kind of filter that is used for dirty discharge of wastewater processing.
Background technology
There is large amount of sewage to handle in modern production, the life.Sewage like toilet, kitchen discharging need be handled through apparatus for treating sewage usually.Isolate or filter and dirt is housed in the apparatus for treating sewage usually, can the solid dirt in the sewage (like hair, sanitary napkin etc.) be isolated filtration thus.Just be provided with filter like the disclosed wastewater forced-draining apparatus of CN101476346.This filter is connected the output of sewage input pipe, and sewage solid dirt when discharging is filtered device and tackles.When being cut dirt more for a long time, the delivery pump in the apparatus for treating sewage promptly begins reverse recoil, thus solid dirt is recoiled to the dirt memory.Existing this type filter is generally the mesh-type filter.Because its mesh of mesh-type filter is relatively intensive,, therefore make recoil also be difficult to it is removed totally so the hair in the dirt, fiber very easily twine through mesh each other.For addressing this problem, the someone adopts the filter cartridge type filter, promptly on a staving, establishes and has several filter openings.Though this design mesh-type filter relatively can effectively alleviate the winding in filter of hair, fiber, its area of passage is little, resistance is big.Therefore it has had a strong impact on the operating efficiency of apparatus for treating sewage.Moreover as long as the existence of filter opening is arranged in the filter, problems such as hair, fiber winding, obstruction just can not fundamentally be resolved.
Summary of the invention
The technical problem that the present invention will solve provides big, the difficult winding of a kind of area of passage, stops up, and is easy to carry out the filter for installation of backflush process.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of grating formula filter, it comprises tubular configured joint and encloses grid in said tubular configured joint one end setting by what grizzly bar constituted; The top ends of said grizzly bar is inwardly gathered.
The present invention in use, tubular configured joint is used for being connected with its supporting equipment or pipeline, encloses the solid waste that the grizzly bar in the grid is used for tackling sewage.Because grizzly bar and the formed void area of grizzly bar will be much larger than mesh or filter openings, so it has effectively increased the area of passage of filter.Moreover the formed three-dimensional space of grizzly bar and grizzly bar can prevent effectively that dirt from stopping up filter, also is convenient to carry out simultaneously backflush process.

Wherein, 1, tubular configured joint, 2, grizzly bar, 3, regulate grizzly bar, 4, symmetrical grating.
The specific embodiment
The present invention includes tubular configured joint 1 and enclosed grid.Enclose the end that grid are arranged on tubular configured joint 1, it is made up of spaced grizzly bar 2, and the top ends of said grizzly bar 2 is inwardly gathered, and constitutes the filter that a three-dimensional space constitutes thus.Tubular configured joint 1 of the present invention is not only the immobilization carrier that encloses grid, and is that the present invention is fixed to its supporting equipment or the connector on the pipeline.
Enclose grid and play interception, filter dirt, it can be grating 4 formations of a pair of symmetry, also can be that grating surrounds more than two pairs, can also be the grid that enclose of a unsymmetric structure or a similar rotation body structure.As long as grizzly bar 2 is gathered formed maximum flow channels inscribed circle diameter less than the diameter of being filtered thing with the maximum spacing and grizzly bar 2 tops of grizzly bar 2.
In order to improve the effect of holding back to dirt, like Fig. 1, Fig. 2, shown in Figure 3, the grid that enclose according to the invention preferably are made up of a pair of symmetrical grating 4; Be provided with adjusting grizzly bar 3 in the joint portion of two gratings 4.So, enclosing grizzly bar 2 in the grid can be arranged in regular with grizzly bar 2 and grid are enclosed in the space comparatively uniformly.
After guaranteeing a pair of grating 4, regulating grizzly bar 3 combinations; Distance between all corresponding each other grizzly bar tops and the distance of regulating between its adjacent grill of grizzly bar are comparatively even; Regulate grizzly bar 3 and when being provided with, can cast aside outward, regulate a pair of grating 4 thus and form pore size when closed.
Hold back, filter the dirt of specifying size for the ease of making and being convenient to control, said symmetrical grating 4 its grizzly bars 2 are all equidistantly arranged with grizzly bar 2.
Or said symmetrical grating 4 is made up of the grizzly bar 2 of interval 0.3-3cm, and the spacing L on its relative grizzly bar 2 tops is less than or equal to the interval S of grizzly bar 2 and grizzly bar 2;
Said symmetrical grating 4 is made up of the grizzly bar 2 of interval 0.3-3cm, and the spacing L on its relative grizzly bar 2 tops also can be more than or equal to the interval S of grizzly bar 2 with grizzly bar 2;
The spacing L on said symmetrical grating 4 its relative grizzly bar 2 tops is identical with the interval S of grizzly bar 2 with grizzly bar 2;
The interval S of said grizzly bar 2 and grizzly bar 2 and the spacing L on relative grizzly bar 2 tops are all less than the diameter of being filtered thing.
Fig. 4, Fig. 5 are the 2nd kind of embodiments of the present invention; Its by tubular configured joint 1 with enclose grid and constitute; The said grid that enclose are surrounded by the grizzly bar 2 that equates at interval, and said grizzly bar 2 top ends are inwardly gathered the flow channels that forms a circle, and the diameter of said flow channels is less than the diameter of being filtered thing; The interval of adjacent grill 2 is less than the diameter of being filtered thing.In this embodiment, grizzly bar 2 equates with the interval of grizzly bar 2, is convenient to isolate the dirt of prescribed level.
Interval as the 3rd kind of embodiment grizzly bar 2 also can be unequal; Perhaps a flow channels is gathered on grizzly bar 2 tops.This flow channels can be that ellipse also can be an irregular figure.
Fig. 6 is the plan structure sketch map of the 3rd kind of embodiment of the present invention; Its by tubular configured joint 1 with enclose grid and constitute; The said grid that enclose are surrounded by the grizzly bar 2 that equates at interval, and the flow channels that forms a rectangle is inwardly gathered on said grizzly bar 2 tops, and the inscribed circle diameter of flow channels is less than the diameter of being filtered thing.
The present invention is installed on and can be used for the pumping line place that sewage pumping station band dirt filters recoil, but is not limited to this.It can also be used for other sewage disposal device or other filtration art.
