Second pond inwall is symmetrically arranged on two with swash plate, and the swash plate bottom is provided with center mud-collecting slot, and the center mud-collecting slot bottom is side by side
It is provided with go back to mud pipe and discharge pipeline, the aerobic zone in the described go back to mud pipe other end connection reaction tank, positioned at the center collection mud
Sludge reflux pump is installed on described time mud pipe pipeline section between aerobic zone in groove and reaction tank, institute is located on described go back to mud pipe
State sludge reflux pump rear side and be provided with sludge stream gauge, between the sludge stream gauge and sludge reflux pump sludge concentration meter is provided with,
The sludge concentration meter side is connected with controller.
As preferred technical scheme, the sludge stream gauge and sludge reflux pump with the controller Electricity Federation.
Used as preferred technical scheme, described time mud pipe mud inlet is less than the discharge pipeline mud inlet.
Used as preferred technical scheme, the discharge pipeline is provided with residual sludge pump.
Used as preferred technical scheme, the inclination angle of the swash plate is 60 °.
(3) beneficial effect
Compared with prior art, it has the advantages that the utility model：Sludge reflux dress of the present utility model
Put, the setting of swash plate causes that sludge settling is fast, concentration is high, and the backflow and discharge of sludge are independent of each other, the setting of controller can be with
The size of effective control sludge back flow quantity, the course of reaction preferably served in reaction tank.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is front view of the present utility model.

8- sludge stream gauge；9- sludge concentration meters；10- controllers；11- residual sludge pumps.
Specific embodiment
A kind of sludge refluxing apparatus, including reaction tank 1 as shown in drawings and the second pond being connected with the delivery port of reaction tank 1
2；The inwall of the second pond 2 is symmetrically arranged on two with swash plate 3, and the bottom of the swash plate 3 is provided with center mud-collecting slot 4, the center collection mud
The bottom of groove 4 is provided with go back to side by side mud pipe 5 and discharge pipeline 6, the aerobic zone in the described go back to other end of the mud pipe 5 connection reaction tank 1, position
Return described between aerobic zone in the center mud-collecting slot 4 and reaction tank 1 on the pipeline section of mud pipe 5 and sludge reflux pump 7 be installed,
The rear side of the sludge reflux pump 7 is located on described time mud pipe 5 and is provided with sludge stream gauge 8, the sludge stream gauge 8 and sludge reflux
Sludge concentration meter 9 is provided between pump 7, the side of sludge concentration meter 9 is connected with controller 10.
Further, the sludge stream gauge 8 and sludge reflux pump 7 with the Electricity Federation of the controller 10.
Further, the described time mud inlet of mud pipe 5 is less than the mud inlet of the discharge pipeline 6.
Further, the discharge pipeline 6 is provided with residual sludge pump 11.
Further, the inclination angle of the swash plate 3 is 60 °.
The utility model is embodied as follows：Sewage is drained in second pond after reacting in reaction tank and carries out muddy water
Separate, being provided with for swash plate is preferably separated beneficial to muddy water, and the high sludge of concentration, sludge just can be collected in the mud-collecting slot of center
Reflux pump starts to extract a small amount of returned sludge, when device to be controlled detects sludge concentration, further according to need backflow sludge quantity by
Controller control sludge stream gauge operation, when required sludge back flow quantity is reached, can data show, now sludge on controller
Reflux pump is out of service, is finally drained excess sludge by residual sludge pump, if in order to improve water treatment efficiency, excess sludge
Pump also can run simultaneously with sludge reflux pump, discharge pipeline mud inlet is less than due to returning mud pipe mud inlet, so the high sludge of concentration
To take the lead in being taken away by sludge reflux pump, not interfere with the carrying out of sludge reflux.
Sludge refluxing apparatus of the present utility model, the setting of swash plate causes that sludge settling is fast, concentration is high, the backflow of sludge and
Discharge is independent of each other, and the setting of controller can be preferably served in reaction tank with the size of effective control sludge back flow quantity
Course of reaction.
