Fully automatic backwash filter

Product Overview
This water treatment filter is mainly composed of a high-quality carbon steel or stainless steel cylinder with a special structure, a stainless steel wedge-shaped filter, a water flow guide valve, a differential pressure controller, an electric control box, and a sewage discharge device. 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 valve to automatically complete cleaning and drainage. The operation mode is automatic operation (it 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 flows through the filter, the water in the water Mechanical impurities are intercepted by the filter. When the impurities accumulated on the surface of the filter increase and the pressure difference reaches
, a signal is sent out when the pressure difference develops. At the same time, a command is issued to start the transmission motor and open the drain valve. The impurities deposited in the filter are brushed off by the rotating brush and discharged from the sewage outlet. The entire scrubbing and sewage process does not require human operation or shutdown. At the same time, the equipment is also equipped with scheduled cleaning and manual cleaning and sewage functions to ensure that it can be cleaned and discharged in any situation. The water discharged from the bottom is safe and reliable.
Scope of application
Steel is used for water treatment and filtration in sintering pellet plants in raw material yards, cooling water filtration in systems such as blast furnace rolling mills and continuous casting machines, and impurity filtration in high-pressure water phosphorus removal systems
Automotive painting production lines, water treatment systems are widely used in automobiles, tractors and motorcycle engine manufacturing
Power plants are used in precision pretreatment parts for the preparation of high-purity water for power plant boilers, filtration of generator cooling water sealing water,
When the water consumption of the system is extremely large, it can be used as a side filtration treatment.
The chemical industry performs side filtration treatment in the circulating water plant. It can be a single machine or multiple models in parallel for main treatment, replacing the filter material filtration and reducing the filtration load of the filter material. , can avoid a large amount of water consumption for flushing and save costs
In agricultural gardens and paper mills with nozzle systems, they should reduce equipment clogging and wear caused by impurities, so they need to choose high-precision and highly automated filtration product machinery
/> The mine filters underground spray water to ensure normal operation of the system.
Other automatic precision filtration of the system is used to prevent clogging of the cooling water system
Control method
The fully automatic backwash filter has It has the function of filtering raw water and automatically cleaning and draining the filter element, and the system provides uninterrupted water supply during cleaning and draining. Currently, there are two fully automatic backwash filter control methods: Manual control
Rotate the manual-automatic selector switch to the manual position, turn on the power to the motor and hydraulic control valve, open the hydraulic control valve, and start sewage discharge. Rotate the selector switch to the automatic position and enter the automatic state. The manual control state is to check the motor and hydraulic The means to control whether the valve can work normally, if it cannot work normally in the manual control state, it will not work properly in the fully automatic control state.
Automatic control
Rotate the manual and automatic selection switch to the automatic position, and first set Filter time and sewage discharge time timer. The lower row of digital tubes of the fully automatic backwash filter timer displays the set value, and the upper row of digital tubes display the timing value. The timer setting method is to press the digit selection button. The first one in the lower row When the digital tube flashes, use the increase key to adjust the value. After adjustment, press the bit selection key again. When the second digital tube flashes, use the increase key to adjust the value, and so on. After setting the time, the digital tube will continue to flash
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.
