Semi automatic stainless steel filter cake layer automatic slag discharge candle filter machine "Price, quotation, manufacturer"

The semi-automatic stainless steel filter cake layer automatic slag discharge candle filter is achieved by manually opening and closing valves to realize the workflow of the candle filter, and to complete the solid-liquid separation of materials; Characterized by affordability and easy maintenance; The candle filter is equipped with multiple filter elements in a closed container, and the filter elements are covered with specialized filter cloth selected according to the characteristics of the liquid. When the liquid passes through the filter cloth, solid substances in the liquid will gradually accumulate on the surface of the filter cloth. When these solid substances reach a certain thickness, a so-called "filter cake layer" is formed. Due to the small gaps between the particles in the "filter cake layer", the escape of impurities in the liquid particles is blocked, which makes the filtrate clear and achieves the ideal filtration effect. When the "filter cake layer" exceeds a certain thickness, the rate at which the filtrate passes through the filter cake layer decreases, and the filtration efficiency deteriorates. At this time, it is necessary to remove the "filter cake layer" and then construct a new "filter cake layer" to start a new filtration cycle. The thickness control of the filter cake layer, cleaning of the filter residue, reconstruction of the new filter cake layer, and monitoring of the filtrate quality are the four technical points and difficulties of the filter cake layer filter.

1. When used for clarifying liquids, additives such as diatomaceous earth and activated carbon can be directly added to the slurry to increase the filtration rate and clarify the filtrate.
2. Fully enclosed operation is suitable for filtering general materials, as well as for filtering hazardous products that are flammable, explosive, toxic, or highly toxic, as well as fresh foods, biological products, and drugs that are not allowed to be contaminated.
3. In the later stage of filtration, if the residual slurry at the bottom cannot be discharged back into the slurry tank, a pump can be used to extract the residual slurry at the bottom, which can then be returned to the top cover of the filter and evenly sprayed onto the filter tube through a nozzle. Compressed gas is then input into the machine to filter out all the residual liquid.
4. Due to the ability of this machine to form a uniform candle filter during filtration, it is convenient to introduce detergent into the machine to wash the filter cake. If the filter cake is washed by top spraying, it can greatly save washing solution.
5. To obtain a dry filter cake, normal temperature air, hot air, or steam should be introduced into the machine after filtration or washing filtration, and passed through the candle filter until the filter cake reaches the desired dryness. Then, the pressure inside the machine should be released and the filter cake should be blown back to discharge from the bottom.
