It has the function of filtering raw water and automatically cleaning and draining the filter element.
The fully automatic filter consists of a housing, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve and a differential pressure controller. The diaphragm in the housing divides the inner cavity into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which fully utilizes the filter space and significantly reduces the filter volume. A backwash suction cup is installed in the lower chamber. .
When the fully automatic filter is working, the turbid liquid enters the lower chamber of the filter through the inlet, and then enters the inner chamber of the filter element through the partition hole. Impurities larger than the gap in the filter element are intercepted, and the clean liquid passes through the gap to reach the filter element. upper chamber, and finally sent out from the exit.
Advantages of fully automatic filters:
The default precision of fully automatic filtration is 100 microns, and can be selected from 100 to 3000 microns. The filter area is large and the dirt holding capacity is high. Users can Customized for actual working conditions. The cleaning method is simple, and the cleaning cycle is electronically monitored, which can realize automatic cleaning and sewage discharge. All parameters in the fully automatic self-cleaning filter control system can be adjusted.
3. Stainless steel brush filter
The types of stainless steel brush filters include: fully automatic stainless steel brush filter, hand-operated stainless steel brush filter. Its main function is to remove suspended solids in the water, reduce the concentration of suspended solids and particulate matter in the water, reduce turbidity, purify water quality, reduce system dirt, bacteria and algae, rust, purify water quality, etc.
The stainless steel brush filter adopts a patented internal mechanical structure to achieve a true high-pressure backwash function, which can easily and thoroughly remove impurities trapped by the filter screen, without dead ends in cleaning, and with no attenuation of flux. , ensuring filtration efficiency and long service life.
The stainless steel brush filter realizes automatic backwashing through its own retrieval and strain functions, which can cope with unstable water quality fluctuations without manual intervention.
During the backwashing process of the stainless steel brush filter, each filter (group) performs the backwash operation in sequence; ensuring safe and efficient cleaning of the filter, while other filters are not affected and continue to filter.
The stainless steel brush filter adopts an automatic drain valve, which has short backwashing time, low backwash water consumption, and is environmentally friendly and economical. There are few wearing parts, no consumables, low operation and maintenance costs, and simple operation and management. According to the filter medium, it is divided into: air filter, liquid filter, network filter and light filter.
Example: Air filter, its prototype is a respiratory protective device used by people to protect their breathing. According to records, as early as the first century in Rome, people used masks made of burlap for protection when purifying mercury. In the long time since then, air filters have also made progress, but they are mainly used as respiratory protection equipment in some dangerous industries, such as the production of harmful chemicals. In 1827, Brown discovered the movement laws of tiny particles, and people had a better understanding of the mechanism of air filtration.
The rapid development of air filters is closely related to the development of the military industry and electronics industry. During World War I, due to the use of various chemical poisons, military gas masks using asbestos fiber filter paper as the smoke filter layer came into being. Glass fiber filter media for air filtration was patented in the United States in October 1940. In the 1950s, the United States conducted in-depth research on the production process of glass fiber filter paper, which led to the improvement and development of air filters. In the 1960s, HEPA filters came out; in the 1970s, HEPA filters using fine glass fiber filter paper as the filter medium had a filtration efficiency of 99.9998% for particles with a diameter of 0.13 microns. Since the 1980s, with the emergence of new testing methods, the improvement of use evaluation and the improvement of filtration performance requirements, it has been discovered that HEPA filters have serious problems, so HEPA filters with higher performance have been produced. ULPA filter. At present, various countries are still working hard on research, and it is estimated that more advanced methods will soon appear
The polluted air can be cleaned to the state required for production and life, that is, the air can reach a certain degree of cleanliness. How the air filter filters the air:
General air purification equipment filters the air and can be roughly divided into the following methods and steps.
1. Multiple filters - prevent dust and germs in the air from entering the room
Multiple activated carbon filters effectively intercept dust and germs, filter the air, and ensure that The air is clean.
2. Titanium oxide anti-virus——degrade formaldehyde, benzene and other organic gas pollution in indoor air
Nano-scale titanium dioxide is activated by ultraviolet light to filter the air and effectively degrade the air Radioactive pollution from organic poisonous gases such as formaldehyde and benzene.
3. Negative ion oxygenation - increasing the oxygen in the indoor air to an appropriate amount and keeping the content stable
