Product Details
The filter is an indispensable treatment equipment in the process of water purification, used to intercept impurities in the water to purify the water or protect the normal work of other equipment in the system. Usually, mesh filters are used in the fields of water filtration and industrial circulating water system due to good filtration effect and low resistance, but their disadvantages are small dirt-holding capacity, easy to be clogged by dirt, complicated cleaning work, and the equipment must be disassembled to realize the cleaning of the filtering part, and the state of the filter cannot be monitored, which is greatly influenced by human factors and makes the automation of the whole system very low. The automatic backwashing filter has the function of filtering the raw water and cleaning and discharging the filter element automatically, and the system has uninterrupted water supply when cleaning and discharging. Compared with the previous filters, this equipment has the advantages of high automation, large processing capacity, self-cleaning and discharging, and uninterrupted water supply, and wide application.
Working Principle
When the backwash filter is working, the water flow guide valve is in the open state, and the water flow enters the filter from the inlet, and flows into the outlet after being filtered by the filter screen. The backwash filter adopts pressure difference control and positioning control to automatically clean the filter screen.
When the pressure difference between the water inlet and outlet of the filter reaches the set value or the timer reaches the preset time, the electric control box sends out a signal, the sewage valve opens, the water flow guide valve is closed, and the water flow washes away the impurities stuck on the inner wall of the filter screen. cleaned out.
When the water flow guide valve is in the fully closed state, the water flow is forced to enter the outside of the filter screen from the mesh of the inlet section of the filter, most of the clean water flows out from the outlet, and part of the clean water enters the inside of the filter screen from the outside of the filter screen (the system is under pressure relief. State, the internal pressure of the filter is less than the external pressure), so as to backwash the filter.
The stainless steel wedge-shaped filter screen with a special structure produces a spray effect inside the filter screen, and impurities are washed away from the smooth inner wall.
When the pressure difference between the inlet and outlet of the filter returns to normal or the timer setting time is over, the electric drain valve is closed and the water flow guide valve is opened. The whole flushing process system can work normally without downtime.
Technical parameters
Self-cleaning time: 10-60 seconds
Single water treatment: 45-2350 /h
Self-cleaning control: differential pressure, time and manual
Maximum working pressure: 0.1-2.5Mpa
Maximum working water temperature: 95℃
Control interface: digital display, knob, switch
Filtration precision range: 100-3000um
Filter type: 304/316Lbubu stainless steel wedge-shaped mesh
Water required for self-cleaning: <1%
Performance characteristics
1, Backwashing filter q device using y has a patented internal mechanical structure, to achieve a true high-pressure backwashing function, can thoroughly remove the impurities trapped in the screen, cleaning without dead ends, loss of very small flow, to ensure the efficiency and long service life of the filter.
2, Backwashing filtration equipment using 304 or 316L stainless steel wedge-shaped screen, with greater strength, will not be corroded to ensure the accuracy of filtration, the highest filtration precision up to 50 microns.
3, Backwashing filter equipment through its own control capabilities to achieve automatic backwashing, can cope with unstable water quality fluctuations, without manual intervention.
4, Backwashing filter equipment has few wearing parts, no consumables, low operation and maintenance costs, and simple operation and management.
5,The backwashing filter control system is responsive and accurate, and the backwashing pressure difference time and time setting value can be flexibly adjusted according to different water sources and filtration precision.
6,During the backwashing process of the filtering equipment, each screen is backwashed in turn to ensure safe and efficient cleaning of the screen, while the other screens are not affected and continue to filter.
7,The filtering equipment adopts electric drain valve, which makes the backwashing time short and the water consumption of backwashing less, which is environmentally friendly and economic.
8,The structure of filtration equipment is compact and reasonable, covering an area of small, flexible and convenient to install and move.
9,The electrical system of filtration equipment adopts integrated control mode, which can realize remote control.
