Embodiment 1

[0014] Configure the cleaning agent for each component in the following table and make the cleaning agent into a cleaning solution:

[0015] Absolute ethanol

[0016] Shandong Jiaojia Gold Mine filters gold concentrate and adds xanthate, black medicine, 2# oil and other beneficiation agents during the beneficiation process. The particle size of the pulp is relatively fine, with a median diameter of 10.72 μm. Add polyacrylamide in the beneficiation and concentration process, the addition amount is 52g / ton. After one month of normal use of the filter, the filter plate attenuated and the problem of not absorbing material appeared. Soak the clogged ceramic filter plate with the surface cleaned and soaked in the cleaning agent to ensure that the water surface is submerged in the water nozzle of the ceramic filter plate. The soaking time is 7 hours. After cleaning, take the filter plate out of the agent and clean it. After cleaning, the ceramic board recovered well, reach...

Embodiment 2

[0018] Configure the cleaning agent for each component in the following table and make the cleaning agent into a cleaning solution:

[0019] Absolute ethanol

[0020] Jilin Huadian Jiapigou Gold Mine filters gold concentrate and adds 2# oil, xanthate and other beneficiation agents during the beneficiation process. Due to the fine particle size of the pulp material, the median diameter is 16.22 μm, and the fine particles below 10 μm account for the total 40%, so a large amount of polyacrylamide flocculant is added in the beneficiation to agglomerate the fine particles and speed up the precipitation. The amount added is 38g polyacrylamide per ton of ore. The flocculant is enriched in the micropores of the ceramic plate and blocks the micropores of the ceramic plate. In normal use, the ceramic plate will be clogged after 2 months, and the suction capacity will decrease. Soak the clogged ceramic filter plate with the surface cleaned and soaked in the cleaning agent to e...

Embodiment 3

[0022] Configure the cleaning agent for each component in the following table and make the cleaning agent into a cleaning solution:

[0023] Absolute ethanol

[0024] Xinjiang Arhada Sanjin Mining Industry filters gold concentrate. Due to the finer particles of the material, a certain amount of polyacrylamide is added during the beneficiation process to assist in accelerating the precipitation of the material to increase the concentration. The median diameter of the material is 12.63 μm, and the addition amount is 36 g / ton. After the filter works normally for 3 months, the material suction effect becomes worse, and gradually develops into no material suction. Clean the ceramic filter tank and the surface of the microporous ceramic filter plate, add water to the tank to the overflow port, add the proportioned medicine into the water, turn on the filter stirring system to fully stir and dissolve the medicine. Turn on the main shaft of the filter to rotate, reduce the ...

Abstract

The invention discloses a cleaning agent for a ceramic filtering plate. The cleaning agent comprises following components in parts by weight: 0.001-0.01 part of hexamethylenetetramine, 0.005-0.05 part of an oxidant, 0.55-2.6 parts of an acidity regulating agent, 0.5-5 parts of an auxiliary agent, 0.1-3.8 parts of a main agent A and 0.5-2 parts of a main agent B, wherein the auxiliary agent is composed of one or more of soluble nitrate and chloride; the main agent A is composed of one or more of soluble fluoride, fluosilicic acid and fluosilicate; the main agent B is soluble acetate. The cleaning agent disclosed by the invention comprises the main agent A and the main agent B; the polyacrylamides flocculating agent in micro-pores of a filtering plate is scattered by the main agent A and the solubility equilibrium is changed; the polyacrylamides flocculating agent is accelerated to be dissolved so as to realize the washing aim.

Description

technical field [0001] The invention relates to the cleaning field of ceramic filter plates, in particular to a cleaning agent for ceramic filter plates. Background technique [0002] The ceramic filter uses the capillary effect of the microporous ceramic filter plate to pump the water in the suspended material through the microporous ceramic filter plate through the vacuum pump, while the solid material cannot pass through the micropores on the surface of the microporous ceramic plate and is trapped in the ceramic plate surface, so as to achieve the purpose of solid-liquid separation. Compared with traditional solid-liquid separation equipment, ceramic filters have the characteristics of high efficiency, energy saving, and environmental protection. In actual production, due to the fine particle size of the mineral material, it is necessary to add a polymer flocculant—polyacrylamide to treat the mineral material in the production, so that the fine particles in the mineral m...
