Cleansing agent for ceramic filter plate

Abstract

The invention discloses a cleansing agent for ceramic filter plate. The cleansing agent for the ceramic filter plate comprises the following raw materials in parts by weight: 0.1-1 part of a principal agent, 0.11-0.6 part of an adjuvant, 0.01-0.1 part of an oxidant and 1.7-6.5 parts of an acidity adjuster. According to the invention, the principal agent is one or two of hydroxy ethyl fork bisphosphonic acid and hydroxy ethyl fork bisphosphonat, the adjuvant is one or more of soluble nitrate, chloride, fluoride and fluoride silicate. The cleansing agent prepared according to the formula can effectively clean and remove blockages on the surface or the inside of micro-pores in the ceramic filter plate, especially a ceramic filter plate in a ceramic filter used for filtrating high-sulphur ore pulp. The cleansing agent can dissolve substances enriched in micropores with a good cleansing effect. Specifically, tests prove that solid-liquid separation rate of a ceramic filter plate washed by the cleansing agent can restore to 70%-82% that of the initial state.

Description

technical field [0001] The invention relates to the technical field of concentrate processing, in particular to a cleaning agent for a ceramic filter plate. Background technique [0002] Ceramic filter is a kind of solid-liquid separation equipment, which is composed of ceramic filter plate, vacuum system, ore supply and discharge system, filtrate discharge system and frame. The vacuum effect of the vacuum makes the slurry in the trough adsorb on the micropores on the surface of the ceramic filter plate under negative pressure, so that the water in the slurry is sucked away through the micropores of the ceramic filter plate and reaches the filtrate discharge system, while the slurry The solid material in the filter is trapped on the surface of the ceramic filter plate because it cannot pass through the micropores, so as to achieve the purpose of solid-liquid separation. Compared with traditional solid-liquid separation equipment, the use of ceramic filters for solid-liquid ...

Problems solved by technology

[0004] Although the cleaning agent disclosed in the above-mentioned prior art can dissolve and remove some micropore blockages, there are more sulfur elements in high-sulfur ore and pyrite, which will sinter in a natural state, so ceramic filtration is used When the plate is used for solid-liquid separation of the pulp of high-sulfur ore, the fine particles in the pulp enter the micropores of the ceramic filter plate, and the phenomenon of rich agglomeration easily occurs, causing the micropores to be blocked. It has been verified by experiments that the cleaning methods currently on the market None of the medicaments can effectively clean it. This problem not only troubles the processing and production of the enterprise, but also severely limits the application range of the ceramic filter.
