Less than or equal to the aperture of fie screen 9, filter residue can be made to tumble in network access case 23 using the inclined-plane of filter screen 22, and filter screen 22 filters
Medium afterwards can meet the requirement of medium transport, guarantee the quality of medium.
Preferably, further, liquidometer 26 is located at the inner cavity bottom dead center position of the second tank body 18, is convenient for
Liquidometer 26 measures the medium in the second tank body 18.
Its detailed connection means is techniques well known, following mainly to introduce working principle and process, specific works
It is as follows.
In use, medium enters from inlet valve 3, primary filter is carried out to medium by coarse strainer 8, then passes through the first circle
Hole 7 enters 9 secondary filter of fie screen, and outlet valve 4 is passed through after filtering and is conveyed, the filtered filter residue of fie screen 9 is in medium pressure
It is adsorbed under power on fie screen 9, will form filter cake when accumulating excessive, fie screen 9 is inside and outside to carry out pressure difference, when outlet valve 4 and slightly
When pressure difference at strainer 8 is more than 16 setting value of pressure difference switch, pressure difference switch 16 sends an electric signal, control to controller 21
Device 21 controls servo motor 15 and the starting of the first solenoid valve 17, and servo motor 15 drives round tube 10 and suction nozzle 11 to rotate clockwise,
Suction nozzle 11 can be made to communicate with the first water pipe 19 by the second circular hole 12, therefore fine filtering can be made under the internal pressure of the first tank body 2
The suction nozzle 11 that filter residue and neighbouring medium on 9 inner wall of net are moved sucks, and sequentially passes through round tube 10, the second circular hole 12 and
One water pipe 19 is discharged into the second tank body 18, and filter screen 22 makes medium pass through filter screen 22 and stay in the second tank body 18 to media filtration
Bottom, while the filter residue on filter screen 22 is washed away in constantly flowing down for medium, make filter residue along the oblique of filter screen 22
Face is fallen into net cage 23, and liquidometer 26 is monitored the volume of medium, when medium volume is greater than 26 inner setting value of liquidometer
When, liquidometer 26 issues electric signal to controller 21, and controller 21 controls second solenoid valve 27 and water pump 28 starts, and makes the second tank
Body 18 is connected to the second water pipe 29, and medium is transported in outlet valve 4 by water pump 28 under itself suction, when pressure difference is less than
When the inner setting value of pressure difference switch 16, controller 21 controls servo motor 15 and the first solenoid valve 17 stops working, and works as medium
When volume is less than 26 inner setting value of liquidometer, controller 21 controls second solenoid valve 27 and water pump 29 stops working, and makes second
There are a certain amount of media in tank body 18, prevent gas from entering in the second water pipe 29, and backwash work terminates, and open cover board 24,
The filter residue in net cage 23 can be made to flow out along hopper 25, be able to achieve the cleaning of filter residue, thus make the more device in backwash,
Medium can be filtered, be transmitted back to the medium of outflow in outlet valve 4, prevent medium from wasting, save cost, pipeline of being more convenient for
Filtering uses.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
