Overview

Candle filter is a closed container that combines multiple porous filter elements. A filter cloth (or other filtering medium) is placed on the outer jacket of the filter element. During filtration, a pump is used to send the slurry into the filter. The liquid phase in the slurry passes through the filter medium and enters the center of the porous filter element, where it is collected and discharged at the clear liquid outlet. Before the formation of the filter cake layer, the discharged "clear liquid" returns to the inlet of the raw slurry and is sent to the filter for circulating filtration until the filter cake layer is formed (meeting the filtration requirements), providing a signal to control the clear liquid to no longer circulate. The clear liquid is sent to the next process for normal filtration through a three-way valve.

Product Details

After a period of normal filtration, when the filter cake layer on the porous wick reaches a certain thickness, a signal is provided to control the feeding (stop), and then the residual liquid in the filter is drained. After draining, a signal is provided to control the blowback port (compressed air, nitrogen or saturated steam) to blow back, causing the filter cake to fall off. After a certain period of blowback, the blowback is stopped and a signal is provided to open the filter slag discharge port for slag discharge. After the slag discharge is completed, the slag discharge port is closed, returning to the initial state before filtration and preparing for the next round of filtration.

Main advantages:

■ 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, with an accuracy range of1Mm~300MmOptional.

■ 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.

■ 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 and return it to the topThe top cover of the filter is placed inside and evenly sprayed onto the filter tube through a nozzle. Compressed gas is input into the machine to filter out all residual liquid.

■ Due to the ability of this machine to form a uniform layer of filter cake during filtration, it is convenient to wash the filter cake by introducing detergent into the machine. If the filter cake is washed by top spraying, it can greatly save washing solution.
