Description
Technical field
The utility model relates to the device to sewage disposal, what be specifically related to is a kind of Sewage treatment systems.
Background technology
Sewage treatment process troublesome poeration and production efficiency are lower, sand filtration unit wherein is after operation for some time, and soil content increases gradually in the filtration medium, and filtration flux reduces gradually, cause water treatment throughput significantly to reduce, filtration medium is recoil (cleaning) regularly.Filtering with recoil is two technological processs of filter plant, filtration is undertaken by filtration channel, filtration channel is made of filter tap, water pump, filtration inlet valve, strainer, filtering outlet valve, and the back flushing passage is made of flush valve, water pump, flushing inlet valve, strainer, flushing outlet valve.Above-mentioned each valve is manual valve, so the mode of recoil is manually recoil at present, can not recoil to filtration medium as required in good time, and inefficiency, labour intensity is large.
Summary of the invention
The purpose of this utility model provides a kind of Sewage treatment systems, and it is used for solving the existing ineffective problem of waste disposal plant.
The technical scheme that its technical problem that solves the utility model adopts is: this Sewage treatment systems comprises slurry tank, strainer, water purification pot, connect and compose filtration channel by pipeline successively by slurry tank, filtration magnetic valve, water pump, filtration entrance magnetic valve, strainer, filtering outlet magnetic valve, water purification pot, on the water outlet pipeline between strainer and the water purification pot flow sensor is installed, flow sensor is connected with controller; Water purification pot, scouring electromagnetic valve, water pump, flushing entrance magnetic valve, strainer, flushing outlet magnetic valve, slurry tank connect and compose the back flushing passage by pipeline successively; Controller is connected with each magnetic valve, each magnetic valve in the back flushing passage in the filtration channel respectively; The sewage inflow hydrograph is connected to slurry tank, on the sewage inflow hydrograph sewage electromagnetic valve is set, and sewage electromagnetic valve connects controller, and water purification pot connects the water purification vent line.
The utlity model has following beneficial effect:
1, the utility model high efficiency can alleviate post personnel's labour intensity.
2, the utility model utilizes the water after purifying in the water purification pot that strainer is carried out back flushing, can save clear water, takes full advantage of and purifies waste water.
3, the utility model can automatically be controlled recoil and filter, when filtration ability, flux descend, the flow that filters water outlet also descends thereupon, when flow was lower than original flow 66%, flow sensor sent pulse signal, controlled the open and close of magnetic valve via programmable logic controller (PLC), to form the technological process of recoil, behind the recoil 15s, programmable logic controller (PLC) resets, and returns to the technological process of filtration.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 slurry tank, 2 strainers, 3 water purification pots, 4 water pumps 5 filter magnetic valve 6 and filter entrance magnetic valve 7 filtering outlet magnetic valves 8 scouring electromagnetic valves 9 flushing entrance magnetic valves 10 flushing outlet magnetic valves 11 flow sensors 12 controllers 13 sewage electromagnetic valves.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this Sewage treatment systems comprises slurry tank 1, strainer 2, water purification pot 3, connect and compose filtration channel by pipeline successively by slurry tank 1, filtration magnetic valve 5, water pump 4, filtration entrance magnetic valve 6, strainer 2, filtering outlet magnetic valve 7, water purification pot 3, flow sensor 11 is installed on the water outlet pipeline between strainer 2 and the water purification pot 3, flow sensor 11 is connected with controller 12, flow sensor 11 is Hall element, and controller 12 is programmable logic controller; Water purification pot 3, scouring electromagnetic valve 8, water pump 4, flushing entrance magnetic valve 9, strainer 2, flushing outlet magnetic valve 10, slurry tank 1 connect and compose the back flushing passage by pipeline successively; Controller 12 is connected with each magnetic valve, each magnetic valve in the back flushing passage in the filtration channel respectively; The sewage inflow hydrograph is connected to slurry tank 1, and sewage electromagnetic valve 13 is set on the sewage inflow hydrograph, and sewage electromagnetic valve 13 connects controller 12, and water purification pot 3 connects the water purification vent line.Programmable logic controller is used for controlling the unlatching of above-mentioned each magnetic valve with closed.
Filter control: sewage is after sewage electromagnetic valve 13 enters slurry tank 1, filtration channel is started working, sewage is after sedimentation, programmable logic controller (PLC) comes controlled filter magnetic valve 5, filtration entrance magnetic valve 6, filtering outlet magnetic valve 7 to open, scouring electromagnetic valve 8, flushing entrance magnetic valve 9, flushing outlet magnetic valve 10 are closed simultaneously, the sewage sedimentation enters water purification pot 3, and effluxes after filtering.
Recoil control: when the flow that has served as filtrate is lower than original flow 66%, flow sensor 11 sends pulse signal, (PLC) controls scouring electromagnetic valve 8 via programmable logic controller, flushing entrance magnetic valve 9, flushing outlet magnetic valve 10 is opened, the back flushing passage is started working, filter simultaneously magnetic valve 5, filter entrance magnetic valve 6, filtering outlet magnetic valve 7 cuts out, filtration channel quits work, at this moment, with the water in the water purification pot 3 strainer 2 is carried out counterflush, time length is 15s, sewage after the flushing enters slurry tank 1 again, again processes.
