Description
Technical field
The utility model relates to technical field of sewage, specially a kind of high rate filter.
Background technique
High rate filter is one of the main device of modern industry water process.Often purified treatment is rolled suitable for iron and steel enterprise
Steel, the muddy water of continuous casting contain filter processing other in iron scale and oil and the circulatory system.In the actual use process, more
Orifice plate is directly welded on cylinder inboard wall mostly.Since high rate filter filter material layer is higher, internal filtrate self weight is heavier, and
Water velocity is very fast when operation, and after running a period of time, after there is certain corrosion in welding position, structure is insecure, it may appear that porous
Plate collapses phenomenon.
For this purpose, we release a kind of high rate filter that structure is more firm to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of high rate filters, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of high rate filter, including cylinder, institute
Cylinder upper end is stated equipped with upper capping, and cylinder lower end is equipped with lower capping, is equipped with wastewater inlet, the cylinder at the top of the upper capping
It is equipped with porous plate with lower capping junction, the diameter of the porous plate is greater than cylinder, lower capping, and porous plate and cylinder, lower envelope
It is fixed together by welding between lid, the porous plate upper end is equipped with filtrate, and the lower closure base portion is equipped with discharge outlet.
This be arranged by being improved to original porous plate, to increase the means of porous plate bulk so that its with
When barrel soldering, has residual volume and be exposed on the outside of cylinder, accordingly even when weld part is corroded, porous plate will not occur and collapse
The phenomenon that.
Preferably, the lower capping side is equipped with inspection socket.
Preferably, the porous plate two sides are equipped with card slot.
This setting is welded convenient for porous plate and cylinder and lower capping.
Preferably, cylinder lower end side is equipped with discharge port.
This setting can replace the intracorporal filtrate of cylinder by discharge port.
Preferably, the inner barrel is equipped with backwash drainpipe, and backwashes the vertical setting of drainpipe in cylinder,
The bottom of the backwash drainpipe is connected to lower capping lower end backwash discharge outlet.
This setting can recycle the sewage in cylinder in backwash by backwash drainpipe.
Preferably, the lower capping lower end is equipped with backwash water inlet.
Compared with prior art, the utility model has the beneficial effects that the utility model is by increasing porous plate,
In welding, porous plate, which can be had a margin, stays in outside cylinder, the risk to collapse so as to avoid porous plate.Its not only simple process,
It is easy to process, and structure is more firm.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the main view of the utility model；
Fig. 3 is the perforated plate construction schematic diagram of the utility model.
In figure: 1 cylinder, capping, 3 lower cappings, 4 wastewater inlets, 5 porous plates, 51 card slots, 6 filtrates, 7 inspection sockets, 8 are unloaded on 2
Material mouth, 9 backwash drainpipes, 10 backwash discharge outlet, 11 discharge outlet, 12 backwash water inlets.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of high rate filter, including cylinder 1, and 1 upper end of cylinder is set
There is upper capping 2, and 1 lower end of cylinder is equipped with lower capping 3, upper 2 top of capping is equipped with wastewater inlet 4, the cylinder 1 and lower envelope
3 junction of lid is equipped with porous plate 5, and the diameter of the porous plate 5 is greater than cylinder 1, lower capping 3, and porous plate 5 and cylinder 1, lower envelope
It is fixed together by welding between lid 3,5 upper end of porous plate is equipped with filtrate 6, and the lower closure base portion is equipped with discharge outlet
11。
Specifically, 2 sides of the lower capping are equipped with inspection socket 7.
Specifically, 5 two sides of porous plate are equipped with card slot 51.
