LSF Type a backwash water filter

??? Automatic water filter, PLC control automatic water filter  Full automatic water filter installation effect drawing

The automatic backwash water filter is used in power station, chemical industry, printing and dyeing, papermaking and other industries. Due to the different sources of water from rivers, lakes and seas, there are various impurities in the water, such as industrial waste, floating grass, fish and shrimp, snail, etc. Sometimes, before entering the pipe side of the water supply and consumption system, simple fence filtration is used, and the conditions are better or the primary filter screen is used for treatment, but there are still some small impurities in the treated water. When they accumulate to a certain extent in the water supply system and do not remove them, it will lead to the reduction of the flow area, and eventually lead to blockage, and even cause shutdown in serious cases, which poses a great threat to the safe operation. In view of the economy, convenience, maintenance and many other factors, our company designed a new type Full automatic backwash water filter Series products, can meet the requirements of users, thoroughly solve the above problems
1. Main technical parameters of water filter
Working pressure ≤ 1.0 MPa
(2) the diameter of filter screen is 3 ~ 8mm
(3) resistance under rated flow ≤ 0.05Mpa
2. Water filter structure and operation instructions:
(1) this series of water filter is composed of ① rotating shaft, ② positioning rod, ③ support shell, ④ mesh core, ⑤ water inlet, ⑥ water outlet and ⑦ sewage outlet (see Fig. Generally, the water quality is fresh water type. The filter screen and internal main parts are made of ordinary stainless steel. If it is sea water or has strong acid-base type, special stainless steel material is used.
??? (2) At this time, the water will flow from the water inlet to the outlet of the filter core automatically because of the water volume difference between the water inlet and the water outlet of the filter core According to the number of sewage outlets, the water can be recycled and discharged automatically.



???
3. Application range of water filter:
(3) the water filter is installed on the side of the water supply pipe below DN500 in power plant, chemical industry, printing and dyeing, papermaking and other industries. It is a small water filter which can replace the secondary filter screen. It has the advantages of small volume, low cost and large filtration flow. It is especially suitable for the branch pipe of water supply of the main pipe, so it has the advantages that the secondary filter can not. In general, there is no need to increase the power source, just use manual, the handle is rotated according to the position of the product, several filter chambers inside the water filter can be cleaned one by one, so as to achieve automatic backwash

DSL automatic self cleaning water filter
The DSL automatic self-cleaning water filter is optimized and refined according to the actual situation of industrial circulating water pipeline in China. Its unique differential pressure drainage can completely solve the problem of jam and net pasting caused by floating objects such as plastic foam, branches, weeds and so on. Moreover, it is easy to flush sediment into the inner cavity of the filter screen, so as to reduce the filtering effect and paste the screen frequently and continuously The problem of shortening normal working hours. In the electrical control mode, PLC automatic logic control is adopted, which does not affect the normal water supply. It can realize remote signal and remote control, and realize the functions of online filtration, automatic cleaning and graded sewage discharge of water filter, which is reliable. According to the cleaning requirements of users, the water filter is automatically completed by the electrical control device according to the preset mode.
1. Features

  1. The filtration area is large and the pressure loss is small.
  2. Filter cleanliness can be made according to user requirements, from 2mm to 6mm.
  3. The automatic water filter is composed of control structure and actuator, the actuator includes reducer, water filter body and electric sewage device; the control mechanism is composed of control cabinet, reducer motor, sewage valve motor and differential pressure controller. According to the requirements of the users, the automatic control of the sewage tank can be realized through the automatic control of the sewage filter.
  4. When discharging sewage, the discharge is small and does not affect the normal operation of the water filter.
  5. The filter screen is made of stainless steel plate, and the filter hole is made of stamping, so that the particles whose diameter is close to the filter screen aperture are easy to pass through, the flow capacity is strong, it is not easy to jam, the pressure loss is small, and the screen will not be pasted for a long time.
  6. The filter screen is made of 2-6mm stainless steel plate, and the mesh core shall be able to withstand the differential pressure of 150 kPa without deformation and damage. It has the characteristics of long working life, corrosion resistance, no rust, smooth surface and no scaling
  7. No need to open the equipment, it can be backwashed to wash off the impurities attached to the filter screen. And automatically open the blowdown valve to drain.
  8. Cycloidal pinwheel reducer is used to realize recoil, which is installed vertically, with compact structure, large output torque, high motor protection level and long service life.
  9.  Before the delivery of the automatic water filter, the automatic backwash water filter shall be packed Full automatic water filter factory debugging, automatic backwash water filter factory inspection

2. Water filter structure
The electric water filter is composed of: Electric cycloid gear reducer mechanism, power distribution control system, differential pressure switch, filter cartridge, electric sewage rotating mechanism, sewage pipe, body, inlet and outlet pipe.
3. How it works
1. Differential pressure drainage: after the DSL automatic self-cleaning water filter is connected to the pipeline system, the water enters the water filter from the lower water inlet, and the water after filtering debris flows out from the water outlet. When the impurities in the water pass through the mesh core, the volume is larger than the mesh core hole, and the vent is intercepted on the mesh core. When a certain amount is accumulated, there is a certain pressure difference between the water inlet and the water outlet. When the water pressure difference between the inlet pressure gauge and the outlet pressure gauge of the filter screen increases to the specified value (the precision diameter of the filter screen is different, and the pressure difference is generally 0.05Mpa), the signal of the differential pressure transmitter is connected with the control signal, and the control mechanism opens the electric drain valve. The electric reducer will run at the speed of 1-3 revolutions per minute. The water flow will reverse wash the impurities and dirt attached to the inner wall of the mesh core The blowdown pipeline and drain valve are discharged into the cooling water outlet, and the attachments are discharged from the filter screen. When the pressure difference in the inner part returns to normal, the blowdown valve is closed to complete the filtration and blowdown process.
2. Regular sewage discharge: the user can set the sewage time within 0-99 hours, which is generally set as once every 6 hours. The time setting can be adjusted according to the water quality. That is to set the time to start the electric reducer for reverse rotation, so that the blowdown valve is opened, and the reverse backwash blowdown is carried out in turn. Until the recoil of all chambers is completed, the electric deceleration mechanism stops working, the electric drain valve is closed, and the blowdown work is completed. Taige power station is the largest power plant in China and abroad, which is widely used in power plant and power plant Product visibility, and has been recognized by all users.
According to the need and possibility, customers can manually turn on the blowdown button for regulation and inspection, and use the system operation mode.
