How high-efficiency self-cleaning filters work

The working principle of the high-efficiency self-cleaning filter must be adopted in the selection of machine equipment models. High-efficiency self-cleaning filter is a kind of filter that immediately prevents sediment, suspended solids, inhalable particles, etc. in the liquid. In addition, it reduces the conductivity of the water and reduces dirt. In addition, it ensures that all the mechanical equipment behind it works normally and has a high service life. Precision equipment, it has the characteristics of automatic drainage.

The working principle of the high-efficiency self-cleaning filter must be adopted in the selection of machine equipment models. High-efficiency self-cleaning filter is a kind of filter that immediately prevents sediment, suspended solids, inhalable particles, etc. in the liquid. In addition, it reduces the conductivity of the water and reduces dirt. In addition, it ensures that all the mechanical equipment behind it works normally and has a high service life. Precision equipment, it has the characteristics of automatic drainage.

The water enters the filter system from the water inlet, first passes through the coarse filter element to filter out large and fine particles of sediment, and then reaches the fine filter, after filtering out fine particles of sediment through the fine filter, the cold water is discharged from the outlet.

During the filtration process, the sediment in the inner layer of the fine filter gradually accumulates, and a pressure difference is formed between its inner and outer sides. When this pressure difference reaches the preset value, it will start the automatic cleaning process: the filter valve is opened, the hydraulic motor room and hydraulic cylinder of the responsible component release the pressure and discharge the water; the hydraulic motor room and suction The pressure of the sewage outside the water pipe is greatly reduced. Due to the air pressure, the waste on the inner wall of the fine filter is sucked by the vacuum suction cup, introduced into the hydroelectric motor room by the hydraulic motor, and discharged by the filter valve, forming a sewage suction process. When the water flows through the hydroelectric motor, the sewage suction pipe is promoted to rotate, and the hydraulic cylinder of the hydroelectric cylinder promotes the axial movement of the sewage suction pipe. Internal surfaces are completely cleaned and clean. All clearing process will last tens of seconds. The filter valve closes at the end of the purge, the increased operating pressure returns the hydraulic cylinder to its initial position, and the filter system is initially fully ready for the next purge cycle. During the cleaning process, the normal filtration work of the chamber filter press continues.

The basic concept that anti-cleaning can be carried out automatically: As mentioned earlier, anti-cleaning is controlled by the opening of the hydraulic solenoid valve and the position of the hydraulic cylinder, and these are controlled by the anti-cleaning controller. The anti-cleaning controller can accurately control the hydraulic solenoid valve and hydraulic cylinder according to the pressure deviation transmitted from the inlet and outlet of the filter system, and the driving force of the controller comes from the pressure of the pipeline itself.

High-efficiency self-cleaning filter features: continuous power supply during back-cleaning, and all back-cleaning should be maintained in the form of a vacuum suction cup net filter. During anti-cleaning, only the small local pressure between the suction cup and the fine filter changes, and the position of the dust collector and hydraulic cylinder does not affect the normal power supply. In addition, the amount of water to be consumed during anti-cleaning is very small. Take a filter system with a flow rate of 300m3/h. The water output is 80-160L.

It can design and process various pressure levels of filtration systems according to customer requirements; the filtration system with a processing temperature of around 95C can be produced through a unique process, and the filtration system that must work under cold conditions will be A unique filtration process control system is adopted; in view of the characteristics of strong corrosion at sea level, raw materials such as nickel and titanium are selected, and the filtration system is manufactured in a unique way; according to the specific load and requirements of customers, we can provide utilitarian solution.

When selecting a filter system, the following factors should be fully considered:

1. Treatment of water output;

2. Pipeline pressure of the system;

3. Filtration accuracy required by customers;

4. Filter the solid mass concentration in the sediment;

5. Filter the relevant physical and chemical properties of chemical substances.
