Ceramic filter has been widely used in solid-liquid separation of mining, metallurgy, chemical industry, papermaking, pharmaceutical, coal, food, environmental protection and other industries because of its high vacuum degree, less vacuum loss, significant energy saving, high production capacity, low moisture content of filter cake, high recovery rate, clear filtrate, no environmental pollution and full utilization of water resources. But the use of ceramic filter mining enterprises on its lack of understanding, do not know the application of vacuum system in ceramic filter, the selection of inappropriate vacuum pump will cause serious impact, according to this actual situation, for everyone to elaborate under the selection of inappropriate vacuum pump will cause what impact, and how we should choose.
Ceramic filter is a kind of dewatering equipment, which is mainly composed of ceramic filter plate, roller system, mixing system, ore feeding and discharging system, vacuum system, filtrate discharge system, scraping system, backwashing system, combined cleaning (ultrasonic cleaning, automatic acid distribution cleaning) system, automatic control system, tank body and frame.
If the inappropriate vacuum equipment is selected and put into use, the working efficiency of the vacuum pump system is often reduced due to the heavy operation load of the vacuum pump, serious wear of the impeller and shell, resulting in the low vacuum degree in the operation of the ceramic filter, which can not work and stop normally, affect the operation of the whole production line and often cause shutdown.
Therefore, we must reform the special vacuum system of ceramic filter.
We know that ceramic filter is composed of various systems. Each system has its own function. Among them, what is the function of vacuum system?
The vacuum pump system is composed of a vacuum pump, a filtrate tank and relevant pipelines. The vacuum pump operates to form a vacuum in the filtrate tank. One end of the relevant pipeline is connected to the filtrate tank, and the other end is connected with the ceramic filter plate through the distribution head, so as to adsorb the solids on the surface of the filter plate, and the filtrate is sucked into the filter tank.
The characteristics of vacuum system: ceramic filter plate has micropores with capillary effect, which makes the capillary force in the micropores greater than the force exerted by vacuum, and the micropores are always filled with liquid, so as to ensure that in any case, the ceramic filter plate has no air to pass through, and water can pass through, so as to achieve solid-liquid separation, and achieve greater vacuum force with its small vacuum power. Therefore, the vacuum system is simple, and the selected vacuum pump has a small displacement, but the system has a high limit vacuum, and the normal vacuum pressure can reach -0.095mpa.
The application of vacuum system in ceramic filter can achieve the following purposes: reduce the failure rate of the original vacuum pump system of the filter, improve the operation reliability of the equipment, at the same time, it can realize the operation mode of multiple ceramic filters sharing one vacuum pump, saving equipment investment and operation and maintenance costs, plus its stable operation, wear resistance and long service life, it is a ceramic filter Filter is the best choice for mining enterprises.
