Product Overview:
This water treatment filter is mainly composed of high-quality carbon steel or stainless steel cylinder, special structure stainless steel wedge-shaped filter, water flow guide valve, differential pressure controller, electric control box and sewage discharge Devices, etc. The entire flushing process system can work normally without downtime.
.
Working principle:
The internal structure of the fully automatic backwash filter is composed of a pig hair brush or a stainless steel wire brush, a stainless steel filter screen and transmission parts. It has a transmission motor and an electric The valve automatically completes cleaning and sewage discharge, and the operation mode is automatic operation (can also be operated manually). The equipment has dual functions of pressure difference and scheduled automatic sewage discharge. Its automation part adopts the most advanced and reliable programmable controller in the world today. When the water flow passes through the filter, the mechanical impurities in the water are intercepted by the filter. When the impurities accumulated on the surface of the filter increase and the pressure difference reaches
.
, the pressure difference develops and sends a signal, and at the same time
That is, a command is issued, the transmission motor starts, the drain valve opens, and the impurities deposited in the filter are brushed off by the rotating brush and discharged from the drain outlet. The entire brushing and draining process does not require human operation or shutdown. At the same time, the equipment is also equipped with scheduled cleaning and sewage discharge and manual cleaning and sewage discharge functions to ensure the safety and reliability of water discharge under any circumstances.
.
Application scope:
Steel: used for water treatment filtration in raw material yards and sinter pellet plants, cooling water filtration in blast furnaces, rolling mills, continuous casters and other systems, and impurities in high-pressure water phosphorus removal systems. Filtration
Automobile: Painting production line, widely used in water treatment systems for automobiles, tractors, motorcycles, and engine manufacturing
Power plant: used for precision in the preparation of high-purity water for power plant boilers Pretreatment part, filtration of generator cooling water and sealing water, can be used as bypass filtration treatment when the system water consumption is extremely large
Chemical industry: bypass filtration treatment is performed in the circulating water field, which can be single machine or multiple machines Type parallel main treatment, instead of filter material filtration, reduces the filter material filtration load, avoids a large amount of flushing water consumption, and saves costs
Agricultural gardens and paper mills: In systems with nozzles and nozzles, the damage caused by impurities should be reduced The equipment is clogged and worn, so it is necessary to choose high-precision, highly automated filtration product machinery.
Mining: filter underground spray water to ensure that the system works normally.
Others: Automatic and precise filtration of the system to prevent clogging of the cooling water system
.
Control method:
The fully automatic backwash filter has the function of filtering the raw water and automatically It has the function of cleaning and draining the filter element, and the system provides uninterrupted water supply during cleaning and draining. At present, there are two fully automatic backwash filter control methods: Fully automatic backwash filter control method
()
Manual control:
Rotate the manual and automatic selection switch to the manual position. The motor and hydraulic control valve are powered on, and the hydraulic control valve is opened to start sewage discharge. Rotate the selector switch to the automatic position to enter the automatic state. The manual control state is a means of checking whether the motor and hydraulic control valve can work normally. If the sewage discharge does not work normally in the manual control state, the fully automatic control state will not work properly either.
()
Automatic control:
Rotate the manual and automatic selection switch to the automatic position, and first set the filter time and sewage discharge timer. The lower digital tube of the fully automatic backwash filter timer displays the set value, and the upper digital tube displays the timing value. Timer setting method: Press the digit selection key once, the first digital tube in the lower row flashes, use the increase key to adjust the value, after adjustment, press the digit selection key again, the second digital tube flashes, use the increase key to adjust the value, in sequence analogy. After setting the time, the digital tube will continue to flash for
seconds. After
seconds, the value will be stored in the memory and will not be lost when the power is turned off. After adjusting the value, press the start button to start timing. If the machine is powered off, the timer will automatically start the next time it is powered on, and the timer will be timed according to the set time.
