Abstract

It is an object of that present invention to provide a kind of good antiscale property electro-osmosis electrode plate devices, are used for sewage treatment industry.Including control cabinet 1, plate and frame filter press 2, walked frame 3, guide rail 4, frictional vibration system 5, power supply 6, anode plate 7, cathode plate 8.Wherein frictional vibration system 5 is formed by motor 501, transmission shaft 502, from rotary head 503, frictional disk 504 and foldable structure 505.The problem of present invention is applied to electro-osmosis biological sewage treatment industry, can effectively solve resistance after cathode plate generates scale and increase, and moisture content of the cake rises, and working efficiency reduces.

Description

A kind of good antiscale property electro-osmosis electrode plate device
Technical field
The present invention relates to sewage treatment industry, especially a kind of good antiscale property electro-osmosis electrode plate device.
Background technique
Currently, the technique of each urban wastewater treatment firm in China is still based on activated sludge, bioanalysis, at dirty places at different levels During reason, need to handle containing the harmful substances such as bacterium and various parasitic ovums.In sewage treatment, sewage it is main Water is broadly divided into capillary water, Interstitial Water, surface attached water and internal water.
What simple mechanical dehydration mode can mainly remove is capillary water and Interstitial Water, remaining moisture is needed by disappearing Heat consumption is removed by the methods of further physics, chemistry, biology.Thus, after mechanical dehydration, due to Still contain large quantity of moisture, so the volume of sludge is still very big.It is, thus, sought for some rationally effective dewatering types come The residual moisture in sludge is removed, to reduce the volume of sludge as far as possible, to be the subsequent processing and transport, discharge of sludge Etc. reducing cost
Electroosmotic dewatering technology is exactly using additional DC electric field, to enhance the method for material dewatering.It is most It is early applied in the in-situ immobilization of soil, is mainly used for removing the organic pollutant and heavy metal substance in soil.By There is good dewatering in electro-osmosis technology, thus the more and more researchers of recent years are applied to sludge dewatering In the middle, achieve the purpose that carry out deep dehydration to sludge.
But during electroosmotic dewatering, adds there are sludge and be heated and cathode is at alkalinity, and then can be the one of cathode screen There is the case where fouling in side, directly results in resistance in this way and increases the case where working efficiency is substantially reduced with strainability variation.It is real It just may need within 1~3 day to carry out a cleaning and descaling process in the use process of border.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the present invention provides a kind of good antiscale property electro-osmosis electrode plate device, from basic Solve electro-osmosis industry cathode plate scale problems.
The concrete composition and principle of the program are:
A kind of good antiscale property electro-osmosis electrode plate device, including control cabinet, plate and frame filter press, walked frame, guide rail, friction vibration Dynamic system, power supply, anode plate, cathode plate.Wherein frictional vibration system is tied by motor, transmission shaft, from rotary head, frictional disk and folding Structure composition.
The present invention is using the scale on the friction removal cathode plate between frictional vibration system and cathode plate frictional vibration, i.e., In the electro-osmosis plate and frame filter press course of work as shown in Figure 1, open every time the fouling condition that cathode screen can be observed after plate desliming or The case where determining cathode plate fouling according to the mud cake water content after desliming in the case of plate and frame filter press real work.Determine that fouling needs When clearing up, control cabinet control friction system is moved to suitable position on walked frame, and frictional disk is overturn 90 ° by foldable structure With cathode screen front face, starting, which carries out friction 10s or so from rotary head and cathode screen, can remove the solids foul of cathode screen.Clearly After reason completes first piece, frictional disk is turned over and is moved to next piece of sheet frame by foldable structure, and frictional disk is overturn 90 ° and yin again Polar net front face starts rotation headband dynamic friction disk and descaling function is realized in cathode plate friction.Scale removal need of work circulation Multiple above-mentioned steps complete the scale removal work of electro-osmosis plate and frame filter press cathode plate.
The beneficial effects of the present invention are: the present invention can solve in the electro-osmosis plate and frame filter press course of work, cathode plate yin The problem of polar net fouling, effectively reduces operating resistance and improves the solid content of mud cake.

Specific embodiment
The present invention is further detailed with reference to the accompanying drawing:
A kind of good antiscale property electro-osmosis electrode plate device schematic diagram shown in FIG. 1, as shown in the figure, the device include: control Cabinet 1, plate and frame filter press 2, walked frame 3, guide rail 4, frictional vibration system 5, power supply 6, anode plate 7, cathode plate 8.Wherein rub Vibrational system 5 is formed by motor 501, transmission shaft 502, from rotary head 503, frictional disk 504 and foldable structure 505.
Specific implementation step is as follows:
The present invention is using the scale on the friction removal cathode plate between frictional vibration system and cathode plate frictional vibration, i.e., In the electro-osmosis plate and frame filter press course of work as shown in Figure 1, open every time the fouling condition that cathode screen can be observed after plate desliming or The case where determining cathode plate fouling according to the water content of desliming in the case of plate and frame filter press real work.Determine that fouling needs to clear up When, control cabinet control friction system is moved to suitable position on walked frame, and frictional disk is overturn 90 ° and cathode by foldable structure Net front face, start from rotary head and cathode screen carry out friction 10s or so can be completed removal cathode screen solids foul it is dynamic Make.After cleaning completes first piece, frictional disk is turned over and is moved to next piece of sheet frame by foldable structure, again overturns frictional disk 90 ° are realized descaling function with cathode screen front face starting rotation headband dynamic friction disk and cathode plate friction.Scale removal work Need to recycle the scale removal work that multiple above-mentioned steps complete electro-osmosis plate and frame filter press cathode plate.
In conjunction with the working principle of plate and frame filter press, optimal step process is as follows:
Plate and frame filter press charging, unloads mud cake, scale removal circulation action at pressure maintaining (logical direct current), completes removing for each cathode plate Dirt work.
Above-mentioned specific embodiment is used to illustrate method and its core concept of the invention, rather than to the present invention into Row limitation.For those skilled in the art, under the premise of not departing from principle of the invention, the present invention is made Any modifications and changes, both fall in protection scope of the present invention.
