Description
Technical field
The present invention relates to a kind of municipal drainage technical field, more specifically, it relates to a kind of municipal wastewater collection system.
Background technology
Community wastewater collect be municipal drainage and sewage disposal important step, the purpose is to by the multiple drainings in cell
The sewage that unit is discharged is collected and is delivered to main conduit discharge or is discharged after being processed by sewage treatment facility.
A kind of publication No. vacuum drainage system collected for municipal wastewater for the patent of invention of CN104652573A is provided
System technology and device, the evacuated tube of connection air is set in vacuum pipe tip, and keying to evacuated tube is controlled, and passes through
Filling into a certain amount of air increases the pressure difference of water column front end face and rear end face so that tip water column can smoothly move ahead.
During work, the sewage of drainage point is first passed through in the header tank that flow by gravity enters nearby, is provided with true in header tank
Blank pipe, vacuum tube extracts the sewage in header tank out, in order to avoid some debris block vacuum tube, in the water inlet of vacuum tube
Set net is provided with, to intercept debris, after the debris in header tank are stacked into certain amount, it is necessary to manually dragged for clearly, with
As a example by one common scenic spot, take up an area 12.5 hectares, it is necessary to set 11 header tanks, once drag for clearly, it is necessary to clear up 11 and catchment
Case, the manpower and materials of consumption are just very big, and cleaning is inconvenient, and disposal costs are high.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of municipal wastewater collection system, can be automatically real
The cleaning reduction disposal costs of the debris in existing header tank
Above-mentioned technical purpose of the invention technical scheme is that：A kind of municipal wastewater collection system, bag
Include the intermediate box for collecting sewage and be arranged on the collecting box of intermediate box side, intermediate box is set higher than collecting box, it is middle
The side of case is communicated with the intercommunicating pore of collecting box and intermediate box, and the intermediate box is provided with the filtering that can cover intercommunicating pore
Net；Vertically sliding is provided with and some pulls centre out for will be deposited in the impurity before screen pack on the inwall of the intermediate box
The clear of case drags for plate, and driving is additionally provided with the inwall of the intermediate box, and dragging for plate does the drive device for pumping clearly.
By using above-mentioned technical proposal：After sewage is flowed into intermediate box, the intercommunicating pore that sewage can be from intermediate box
Interior outflow, into collecting box, the screen pack being arranged in intermediate box can be filtered to impurity, so be entered in collecting box
Sewage is, by preliminary filtering, do not have larger impurity, will not be blocked vacuum tube, in draining, in screen pack front end
Some impurity can be gathered, plate is dragged for clearly can be picked up these impurity and be expelled to outside intermediate box, realize the automatic cleaning of impurity,
So there is no need to manually be cleared up, the labour intensity of operating personnel is reduced, additionally, drive device can drive drags for plate clearly
Slide up and down, realization is dragged for clearly automatically, is further reduced labour intensity and is dragged for cost clearly.
