subject: Water Filter Equipment Of Self Cleaning Filter For Water Treatment [print this page] Self cleaning filter is composed of shell body, stainless steel filter net, preclusive sewage mechanism, transmission device and electric control part.
When water filter works, waste water will flow from the mouth of the filter, through the filter net and reaches the pipeline needed by the users. This is a recycling process. The Impurity particles in the water will be retained in the interior of the filter net by recycling. Therefore, more and more particles will be retained through the unceasing circulation. Although the filtration speed will be made more and more slowly, the waste water sill flows into the water filter continuously. As the filter hole will become smaller and smaller, it forms pressure difference between the inlet and outlet. When the pressure difference reaches the standard value, differential pressure transmitter will transmit the signal to the controller which will start the driving motor to drive the axis to move around by the transmission component. At the same time, the mouth of the preclusive sewage will be opened and the waste water will be flowed out through the preclusive sewage outlet. When the filter net cleaning is finished, pressure difference will be reduced to the minimum value. At this time, the system will return to the initial condition. Everything will be operated normally.
The water filter possessed many advantages, as follows:
Firstly, High precision
The feature can assure the stability of the water output quality.
It realized automatic reverse circulation washing by itself searching and strain function without manual intervention.
Thirdly, at the same time of reverse circulation washing, the equipment can output water without interrupting.
Fourthly, high efficient cleaning function. The filter net doesn't need to be replaced because it can be restored to the initial condition completely after cleaning.
Fifthly, the time of reverse circulation washing is short. It saves both water and electricity.
Sixthly, the structure design is reasonable, occupies a small area and convenient for moving and installation.
Self cleaning filter are widely used in metallurgical, chemical, oil, paper, pharmaceutical, food, mining, electric power, city water supplying field. Such as the filter of industrial waste water, emulsion regeneration, waste oil filter treatment, metallurgical industry, continuous casting water system of blast furnace water system, high pressure water descaling system for hot rolling. It is a kind of the advanced automatic filter device indeed which is not only high efficient but also easy to operate.
