Description
Technical field
The utility model relates to a kind of filter.
Background technology
In commercial production, contain a large amount of suspended impurities in industrial lean solution or the industrial wastes.After industrial lean solution like this or industrial wastes need be removed suspended impurity wherein through liquid filter, could be utilized once more or recycled.
For example, in the absorption liquid circulation absorption process of sinter fume, at first, in the sulfur dioxide absorption system, contain a large amount of SO
2The flue gas of compositions such as gas and a large amount of dust contacts with desulfuration solution (absorption liquid), thus the SO in the flue gas
2Compositions such as gas and a large amount of dust get into desulfuration solution formation and contain a large amount of SO
2" rich solution "; Then, in the sulfur dioxide desorption system, the rich solution that contains mentioned component is separated sucking-off SO
2Gas, SO
2Gas obtains recycling.Like this, SO
2The sintering flue gas desulfurization solution that gas is separated sucking-off contains a large amount of suspensions, makes desulfuration solution become and does not contain SO
2And by " lean solution " of deteriorations such as suspension.Absorb sinter fume for the desulfurization lean solution that makes deterioration continues on for circulation in whole system, need a large amount of suspension in the desulfurization lean solution be removed, so that in the sulfur dioxide absorption system, be used to absorb flue gas.
Usually, utilize liquid filter that the suspension in the desulfurization lean solution is removed, so that the utilization once more of desulfurization lean solution.In the process of utilizing filter that the desulfurization lean solution is filtered; Suspension in the desulfurization lean solution can be deposited on the cartridge surface of filter; And filter is long more running time, and it is many more that suspension deposits on the surface of filter core, causes the filter efficiency of filter to reduce greatly.Therefore, need filter core be disassembled from filter aborning, the suspension that deposits on the cartridge surface is removed.This has not only wasted manpower, and production efficiency is reduced greatly.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and the liquid filter that provides a kind of suspension that will be deposited on the cartridge surface automatically to remove.
Liquid filter according to the utility model comprises: upper shell is provided with liquid outlet; Lower shell is provided with inlet and compressed air mouth; Dividing plate is arranged between upper shell and the lower shell, in dividing plate, is provided with a plurality of through holes; A plurality of filter cores are arranged in the lower shell and are attached to the through hole in the dividing plate.
According to the liquid filter of the utility model, be provided with sewage draining exit in the bottom of lower shell.Sewage draining exit is provided with valve.The compressed air mouth is provided with valve.Filter core is provided with a plurality of inlets, and filter screen is coated on the outside of filter core.Filter screen is coated on the outside of filter core through the stainless steel steel wire.
According to the liquid filter of the utility model, can feed compressed air through compressed air mouth and stir the liquid in the lower shell in the lower shell setting, the suspension that is deposited on the cartridge surface is rinsed out, thus the cleaning of completion cartridge surface.
Description of drawings
The following description of the exemplary embodiment of carrying out in conjunction with the drawings, these of the utility model and/or other aspects and advantage will become clear and be easier to and understand, wherein:
Fig. 1 is the cutaway view according to the liquid filter of the utility model;
Fig. 2 is the cutaway view along the A-A line intercepting of Fig. 1;
Fig. 3 is the sketch map according to the filter core of the liquid filter of the utility model.
The specific embodiment
Describe liquid filter in detail with exemplary embodiment below with reference to accompanying drawings according to the utility model.
Fig. 1 is the cutaway view according to the liquid filter of the utility model, and Fig. 2 is the cutaway view along the A-A line intercepting of Fig. 1.
See figures.1.and.2, comprise upper shell 1, dividing plate 2, lower shell 3 and a plurality of filter core 4 according to the liquid filter of the utility model.
The top of upper shell 1 can be provided with cover plate 5, but the utility model is not limited thereto, and for example, upper shell 1 can form as one with cover plate 5.According to the exemplary embodiment of the utility model, upper shell 1 can be bonded to each other through bolt 10 with cover plate 5.The sidewall of upper shell 1 can be provided with liquid outlet 6, but the utility model is not limited thereto, and liquid outlet 6 can be arranged on the cover plate 5.
Dividing plate 2 is arranged between upper shell 1 and the lower shell 3, and upper shell 1 and lower shell 3 are combined.Upper shell 1, dividing plate 2 and lower shell 3 can be bonded to each other through bolt 11.Being provided with a plurality of through holes 12 in the dividing plate 2 combines with filter core 4 being used for.
A plurality of filter cores 4 are arranged on the inside of lower shell 3 and are provided with accordingly with a plurality of through holes 12 in the dividing plate 2.That is, filter core 4 is attached to through hole 12, so that liquid gets into the upper shell 1 through a plurality of filter cores 4 from lower shell 3.
Fig. 3 is the sketch map according to the filter core of the liquid filter of the utility model.
With reference to Fig. 3, be provided with by a plurality of inlet H on the filter core 4.The filter screen (not shown) is coated on through stainless steel steel wire 18 on the surface of filter core 4, can't continue to use to be corroded at filter screen and is convenient to the dismounting and the installation of filter screen when changing filter screen.Label 17 among Fig. 3 is a pressing plate, and it act as the end of pushing down the filter screen perk.
According to the exemplary embodiment of the utility model, filter core 4 is attached to through hole 12 places of dividing plate 2 through convexity 16 and the bolt that passes bolt hole 15.But the utility model is not limited thereto, and filter core 4 can be fixed to through hole 12 places of dividing plate 2 through other mode.
Operation according to the liquid filter of the utility model will be described in detail belows.
In use, liquid gets into lower shell through inlet 7, and the inlet H through filter core 4 gets into upper shell 1 under the effect of pressure, thereby from liquid outlet 6 outflow filters.Owing to be coated with filter screen on the inlet H of filter core 4, so the sedimentation of suspension in the liquid is on the surface of filter core 4.Like this, behind the liquid filter long-play, the suspension that deposits on the surface of filter core 4 is too much, and the filter efficiency of liquid filter is reduced greatly.At this moment, stop feed liquor in liquid filter, and, in lower shell 3, blast compressed air through compressed air mouth 9 with the valve open of compressed air mouth 9.Liquid in the compressed air stirring lower shell 3 will be deposited on filter core 4 lip-deep deposits and wash.Then, with the valve closing of compressed air mouth 9 and with the valve open of sewage draining exit 8, discharge will contain the sedimental liquid that washes.Wait to contain after the sedimental liquid that washes arranged, close the valve of sewage draining exit 8, thereby can continue to use filter that liquid is filtered.
Through can finding out to above description according to the liquid filter of the utility model exemplary embodiment, can clean automatically through the compressed air mouth according to the liquid filter of the utility model, carry out manual work and clean and need not filter core dismantled.
