The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of hydro powered type filter, including shell
1, the top in 1 left side of shell is provided with blowdown valve 2, and the bottom of shell 1 is provided with branch pipe 7, and the bottom end of branch pipe 7 is communicated with straight pipe
14, it is connected to by side pipe 15 with the top of straight pipe 14 on the right side of shell 1, first butterfly valve 11 is provided on side pipe 15, is set on branch pipe 7
It is equipped with second butterfly valve 12, third butterfly valve 13 is provided on straight pipe 14, the left side of shell 1 is disposed with pressure difference from top to bottom
Table 3 and electric controller 4 are provided with hydraulic motors 9 at the top of 1 inner cavity of shell, and the output end of hydraulic motors 9 is provided with and hydraulic motors
9 hydraulic pistons 8 being equipped with, the inner cavity of shell 1 are provided with the dirt trap 16 being equipped with hydraulic piston 8, dirt trap 16
Bottom end be provided with flow control device 6, be communicated with suction nozzle 10 on dirt trap 16, the quantity of suction nozzle 10 is two, and suction nozzle 10 and collection
The inner cavity connection of dirty device 16, the inner cavity of shell 1 and the two sides for being located at dirt trap 16 are provided with strainer 5, and strainer 5 is stainless steel filter
Flow control device 6 includes flow control shell 65, and the bottom end of dirt trap 16 runs through the top of flow control shell 65 and extends to control
The inner cavity of shell 65 is flowed, the bottom of flow control shell 65 is fixedly connected with leakproof rubber 64, offers on leakproof rubber 64 and flow control
The through-hole 61 that shell 65 is equipped with, the inner cavity of flow control shell 65 are provided with the plug 63 that blocks water, and the two sides at 63 top of plug that blocks water are solid
Surely it is connected with the bar 62 that blocks water, the top for the bar 62 that blocks water runs through the inner wall of flow control shell 65 and extends to the outside of flow control shell 65,
The top of flow control shell 65 is fixedly connected by reset spring 66 with the top for the plug 63 that blocks water, and reset spring 66 surround and is set to
Block water the surface of bar 62.
When work, drive hydraulic motors 9 to operate by the strength of water flow, hydraulic piston 8 constantly carry out piston motion incited somebody to action
Filtrate is delivered to filter interior and is filtered operation, and sewage is left in dirt trap 16 filtered fluid after filtering, and clear water is through straight
The right end of siphunculus 14 is discharged, and strainer 5 stays impurity because prolonged filtration may be stained with, by various regions water quality situation, every 4-6
It is cleaned, and (user can control cleaning by way of control first butterfly valve 11, second butterfly valve 12 and third butterfly valve 13
The flow direction of liquid, to carry out cleaning operation to filter).
When the 63 lower section hydraulic pressure of plug that block water are greater than top, block water and fill in 63 under the action of blocking water bar 62 relative to flow control shell
65 move up, so that water flow is entered in dirt trap 16 by flow control shell 65, when blocking water, 63 lower section hydraulic pressure of plug are less than
When top, makes flow control shell 65 relatively closed under the action of blocking water plug 63, to avoid liquid reflux, further reduced
The difficulty of cleaning operation.
In conclusion the hydro powered type filter, by the improvement of flow control device 6 and blowdown valve 2, differential pressure indicator 3,
