Embodiment 1

[0033] Please see figure 1 , figure 1 It is a schematic diagram of specific steps of the ceramic filter plate cleaning method of the ceramic filter of the present invention. 10 in the figure is the surface treatment step of the present invention: place the ceramic filter plate to be treated on the operating platform, take a small King Kong S1M-SH06-100A angle grinder with a power of 580W, turn on the power supply, and the operator holds the angle grinder Machine, grind the surface of the ceramic filter plate for 10-30 minutes (depending on the clogging situation), after the surface of the ceramic filter plate is uniform, finish the surface grinding process. 20 among the figure is the chemical cleaning step of the present invention: put 5% nitric acid into the hard plastic case with cover, place the ceramic filter plate after the surface treatment in the above-mentioned hard plastic case with cover after 5 days, take out the ceramic Filter plate, end the chemical cleaning pro...

Embodiment 2

[0037] Place the ceramic filter plate to be processed on the operating platform, take a small King Kong S1M-SH06-100A angle grinder with a power of 580W, turn on the power, and the operator holds the angle grinder to grind the surface of the ceramic filter plate for 20 minutes First, after the surface of the ceramic filter plate is uniform, the surface grinding process is completed.

[0038] After the above surface treatment of the ceramic filter plate, the water permeability test was carried out, and the water permeability of the ceramic filter plate was 1.30T / m 2 H. (Note: the previous water permeability of the ceramic filter plate in this embodiment is 2.00T / m 2 H, after 3 months of work, the ceramic filter plate has a water permeability of 0.7T / m 2 H, after the above treatment, the water permeability of the ceramic filter plate is 1.30T / m 2 H. ).

Embodiment 3

[0040]Place the ceramic filter plate to be processed on the operating platform, take a small King Kong S1M-SH06-100A angle grinder with a power of 580W, turn on the power, and the operator holds the angle grinder to grind the surface of the ceramic filter plate for 20 minutes First, after the surface of the ceramic filter plate is uniform, the surface grinding process is completed. 5% nitric acid is put into the hard plastic box with cover, and the ceramic filter plate after the surface treatment is placed in the above-mentioned hard plastic box with cover for 5 days, then the ceramic filter plate is taken out, and the chemical cleaning process is finished.

[0041] After the ceramic filter plate has undergone the above surface treatment and chemical cleaning process, the water permeability test is carried out, and the water permeability of the ceramic filter plate is 1.40T / m 2 H. (Note: the previous water permeability of the ceramic filter plate in this embodiment is 2.00T / m...

Abstract

The invention relates to a method for cleaning a ceramic filter plate of a ceramic filter. The cleaning method comprises a surface treatment step of the ceramic filter plate, wherein the surface treatment is surface polishing treatment of the ceramic filter plate. The cleaning method also comprises a chemical cleaning step, an ultrasonic cleaning step and a high-pressure water flushing step. The method has the advantages of simpleness in operation of the four steps and low cost, and greatly prolongs the service life of the ceramic filter plate; and the cleaning method can be reused, greatly reduces the operation cost of the ceramic filter, and can be popularized and applied to the filter plate of the ceramic filter.

Description

【Technical field】 [0001] The invention relates to the technical field of cleaning methods for ceramic filter plates, in particular to a cleaning method for ceramic filter plates of ceramic filters. 【Background technique】 [0002] The ceramic filter uses a "water-permeable and air-impermeable" porous ceramic plate as the filter medium, replacing the filter cloth, thus making a qualitative leap in its performance. As a filter medium, the ceramic filter plate plays a key role in the high efficiency and energy saving of the ceramic filter. Due to its capillary force, only water can pass through the filter plate during the filtration process, while air cannot pass through, and the vacuum degree is relatively high. It can be seen that the ceramic filter plate is a key component of the ceramic filter, and its cleaning effect is related to the production capacity, service life and equipment operation rate of the ceramic filter. [0003] After a certain working time of the ceramic ...
