[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0035] The present application provides a sedimentation tank, including a sedimentation tank body, at least one sludge hopper, a suction mechanism, a detection device and a control mechanism. The sedimentation tank body is used to perform sedimentation treatment on sewage. At least one sludge hopper is arranged at the bottom of the sedimentation tank body, and is used to store sediment in the sedimentation tank body. The suction mechanism is connected to the sludge hopper, and is used to suck the sediment and discharge the sediment. The detection device is used to detect the chemical oxygen demand of the liquid after the sedimentation treatment. The control mechanism is arranged on the sedimentation tank body, and the control mechanism is electrically connected to the suction mechanism and the detection device. The chemical oxygen demand of the liquid after the sedimentation treatment is detected by the detection device to obtain the sedimentation treatment information of the sewage by the sedimentation tank body. The control mechanism controls the start or shut down of the suction mechanism according to the information detected by the detection device, so as to realize the automatic suction of the sediment in the sludge hopper, thereby ensuring the use effect of the sedimentation tank body, reducing labor intensity, saving labor costs, and improving the cleanliness of the production site.

[0036] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0037] like Figure 1-Figure 2 As shown, an exemplary embodiment of the present application provides a sedimentation tank, including a sedimentation tank body 1, at least one sludge hopper 2, a suction mechanism 3, a detection device 4 and a control mechanism 5; the sedimentation tank body 1 is used to perform sedimentation treatment on sewage, and at least one sludge hopper 2 is arranged at the bottom of the sedimentation tank body 1, for storing the sediment in the sedimentation tank body 1; the suction mechanism 3 is connected to the sludge hopper 2, for sucking the sediment and discharging the sediment; the detection device 4 is used to detect the chemical oxygen demand of the liquid after the sedimentation treatment; the control mechanism 5 is arranged on the sedimentation tank body 1, and the control mechanism 5 is electrically connected to the suction mechanism 3 and the detection device 4.

[0038] In this embodiment, after the sewage enters the sedimentation tank body 1, after multi-stage sedimentation treatment, the upper layer of liquid after the sedimentation treatment is discharged, and the lower layer of sediment is left in the sludge hopper 2; at the same time, the chemical oxygen demand (COD) of the liquid after the sedimentation treatment can be detected by the detection device 4. When the detection device 4 detects that the COD value of the liquid exceeds the COD setting value, it indicates that the sedimentation effect of the sedimentation tank has decreased, and more sediment has been stored in the sludge hopper 2; the detection device 4 transmits the detection information to the control mechanism 5, and the control mechanism 5 controls the suction mechanism 3 to start, so as to suck the sediment in the sludge hopper 2 and discharge the sediment. When the detection device 4 detects that the COD value of the liquid after the sedimentation treatment does not exceed the COD setting value, it indicates that the sedimentation effect of the sedimentation tank is good, and less sediment is stored in the sludge hopper 2; the detection device 4 transmits the detection information to the control mechanism 5, and the control mechanism 5 controls the suction mechanism 3 to close to stop the suction of the sediment in the sludge hopper 2. The present application can realize automatic suction of the sediment in the sludge hopper 2 through the cooperation of the detection device 4, the control mechanism 5 and the suction mechanism 3 to ensure the use effect of the sedimentation tank body, reduce labor intensity, save labor costs, and improve the cleanliness of the production site, and has strong practicality and economy.

[0041] In this embodiment, the suction force generated by the operation of the axial flow pump 31 transfers the sediment in the sludge hopper 2 to the sewage pipe 33 through the connecting pipe 32 for discharge.

The other end of the third sub-segment 3323 is connected to the third sewage sub-pipe 333.

Among them, the operation time of the motor of the axial flow pump 31 can be set in advance through the time switch 51 according to the capacity of the sludge hopper 2 and the suction efficiency of the axial flow pump 31; when the axial flow pump 31 is started, the time switch 51 automatically starts the countdown, and after the set time is reached, the time switch 51 cuts off the power supply of the motor of the axial flow pump 31, so that the axial flow pump 31 stops running, and the cleaning work of the sludge hopper 2 is completed.

[0050] In one embodiment, the control mechanism 5 further includes a signal indicator light 52 , and the signal indicator light 52 is electrically connected to the controller.
