What is the structure of the automatic filter housing?

The full-automatic filter housing overcomes many shortcomings of the existing filter products, such as small pollution, easy to be blocked by dirt, the need to decompose the filtering part, and the inability to monitor the filtering state. It has the functions of filtering water source and automatically cleaning the filter. When cleaning dirt, the system can continuously supply water and monitor the working state of the filter, with a very high degree of automation.

Self cleaning filtration technology is a new filtration technology developed in the late 1970s. Its great advantages are water pressure self operation, self-cleaning and non-stop filtration during cleaning. Compared with the traditional filter, it has high degree of automation and small pressure loss, so manual slag removal is not required. The self-cleaning filter is applicable to the separation and filtration of industrial, agricultural and municipal seawater desalination processes.

What is the structure of the automatic filter housing?

The automatic self-cleaning filter housing is composed of shell, multi-element filter, backwashing mechanism, electric control box, reducer, electric valve, differential pressure controller, etc. The inner diaphragm of the shell divides the inner cavity into upper cavity and lower cavity. The upper cavity is equipped with multiple filters to make full use of the filtering space and greatly reduce the filtering volume. The lower cavity is equipped with backwashing air suction plate. During the working process, the turbid liquid enters the filter through the inlet and drops, and enters the inner cavity of the filter through the diaphragm hole. The impurities larger than the filter gap are blocked, and the net value reaches the upstream through the gap and is sent out from the outlet.

What is the working principle of automatic filter housing?

Water containing impurities enters the filter from the inlet, first through the coarse filter for coarse filtration, and then into the inner cavity of the fine filter for fine filtration, and the filtered integer flows out from the outlet. The filtered impurities are adsorbed on the micro filter, forming the differential pressure between the inner and outer surfaces of the filter. When the pressure difference reaches the set value (e.g. 0.5 bar), the pressure sensor transmits a signal to the controller, and the controller opens the exhaust valve 4 and discharges it from the exhaust port. Results the pressure of hydraulic motor steel and impurity collector and chamber decreased, resulting in negative pressure suction similar to the principle of vacuum cleaning. The impurities on the filter surface are discharged into the sewer through backwash water and hydraulic motor and discharged through the discharge port. The drainage makes the hydraulic motor and debris collector rotate, which can clean the whole filter. The large filter also includes a drive cylinder to control the longitudinal movement of the impurity collector and prevent the whole filter from moving too fast for cleaning by the nozzle. The whole backwashing process is automatically controlled within a few seconds, and the main water will not be interrupted during the self-cleaning process.

What is the service scope of automatic filter housing?

The full-automatic filter is mainly used for purifying water. It can be used for water filtration, water treatment and water transformation in industries, agriculture, electric power, electronics, medicine, food, printing and dyeing, construction, steel, metallurgy, papermaking, coal mine, swimming pool, landscape, greening and other industries, especially water quality
