Based on the above structure, the cleaning method of the gas-dissolved water cleaning type plate-and-frame filter press of the embodiment includes: the embodiment firstly provides a method for cleaning filter cloth of a plate and frame filter press by dissolved gas water, which comprises the following steps:
1. sealing, namely sealing the filter plate assembly 200 of the plate and frame filter press so as to form a sealed space in the filter plate assembly 200;
2. a gas-dissolved water generation step, namely sequentially injecting water and compressed air into the sealed space and enabling the water and the compressed air to form gas-dissolved water;
3. a dissolved air water releasing and cleaning step, wherein the sealing of a sealed space is released, so that bubbles in the dissolved air water release and clean a filter assembly to enable the dissolved air water to fill the sealed space, and the filter plate assembly is cleaned for a preset time;
4. and a water drainage step, namely draining the cleaned water body.
The principle of the method is that compressed air is pressed into clean water in a closed state, and a large amount of compressed air is gradually dissolved in the water along with the increase of the pressure of the gas-water mixture to form gas-dissolved water with uniform components. The filter cloth of the filter press is soaked in the dissolved air water, the dissolved air water can soften and dissolve the dirt on the filter cloth (when acid water is used), and when the pressure on the water outlet side of the filter cloth suddenly drops (namely the sealing of a sealed space is removed), the dissolved air in the dissolved air water can quickly generate a large amount of bubbles with strong kinetic energy, so that the dirt and the filter cloth can be stripped and taken away through the water body, and the aim of cleaning the filter cloth is fulfilled.
The sealing step of this embodiment comprises: the plurality of filter plates 210 of the filter plate assembly 200 are moved to be attached to each other, and a water containing space is formed between the two attached filter plates, and the plurality of water containing spaces are communicated to form a sealed space.

As a preferred embodiment of this embodiment, the step of generating the dissolved gas water of this embodiment includes: opening a water inlet 300 of the plate-and-frame filter press, and injecting water into the sealed space; after water is injected to a preset water amount, the water inlet 300 is closed; opening the compressed air inlet 600 and injecting compressed air into the sealed space; after the sealed space reaches the preset pressure value, the compressed air inlet 600 is closed.
In the embodiment, the gas-dissolving water is not directly introduced into the sealed space, but is generated in the sealed space, so that the reduction of bubbles of the gas-dissolving water caused by pressure change in the gas-dissolving water conveying process is avoided.
As a preferred embodiment of this embodiment, before opening the water inlet 300, the method further includes opening the evacuation port 400, where the evacuation port 400 is communicated with the sealed space, so as to prevent the sealed space from affecting the water inlet, and part of air can be discharged while the water is entering, so that the whole sealed space can be filled with the water.
In combination with the above structural description and method description, compared with the existing cleaning method described in the background art, the cleaning method of the dissolved air water cleaning type plate-and-frame filter press provided by the embodiment has the following advantages:
1. the filter cloth can be cleaned by dissolved air water, so that the filter cloth is more thorough in cleaning and better in effect.
2. Each filter plate uses only 15-30 liters of water, and only about 10 percent of other cleaning methods.
3. The cleaning time is 1-1.5 hours, which is more efficient than other cleaning methods.
4. No splash generated by other cleaning methods during cleaning, and no environmental pollution.
5. The air compression device, the sludge inlet, the sludge outlet and other structures of the existing plate-and-frame filter press can be utilized, and the overall cost is reduced.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
