DETAILED DESCRIPTION

[0012] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] like Figure 1-3 The utility model is a sewage sedimentation device, comprising a treatment container 1, which comprises a shell 101, a water inlet pipe 102 and a drain pipe 103 installed on the side wall of the shell 101 and distributed up and down, a sewage pipe 104 installed at the lower part of the shell 101, and a support 105 also installed at the lower part of the shell 101 and in contact with the placement surface. The water inlet pipe 102, the drain pipe 103 and the sewage pipe 104 are all equipped with on-off valves. When in use, the on-off valve on the water inlet pipe 102 is opened, and the on-off valves on the drain pipe 103 and the sewage pipe 104 are closed. The sewage enters the shell 101 through the water inlet pipe 102 and can be subsequently precipitated.

[0016] In order to shorten the time of sewage treatment sedimentation and improve the efficiency of sewage treatment sedimentation, the device also includes a bracket 2 installed on the upper part of the shell 101, and a driving device 3 is installed on the bracket 2. The driving device 3 can be a push rod device, and the piston rod of the push rod device is facing downward. The piston rod is connected to a sedimentation treatment device 6 through a connecting shaft 601, and the sedimentation treatment device 6 includes a circular mounting ring 604 connected to the other end of the connecting shaft 601, and a filter screen 602 is installed on the mounting ring 604. The filter screen 602 can be composed of a plurality of circular partition screens stacked. When in use, the filter screen 602 is set to be composed of a plurality of circular partition screens to enhance the isolation effect of impurities, so as to improve the sewage treatment quality of the device. When in use, the control drive device 3 is started to extend and retract its piston rod, driving the sedimentation treatment device 6 to rise until the filter screen 602 is located above the water inlet pipe 102, and then the sewage enters the housing 101 through the water inlet pipe 102, and the control drive device 3 is controlled to make its piston rod drive the sedimentation treatment device 6 to descend, and the filter screen 602 descends in the sewage, and the impurities in the sewage are pushed downward by the filter screen 602 for isolation, and the filter screen 602 continues to descend. When the filter screen 602 descends to the bottom of the drain pipe 103, the water and impurities are separated, and the on-off valves of the drain pipe and the sewage pipe are opened, and the water is discharged from the drain pipe 103, and the impurities are discharged from the sewage pipe 104. In actual use, flocculants can be added to the sewage, and the suspended particles in the sewage are condensed with each other to increase the size of the particles to form flocs. When the flocs grow to a certain volume, they can be more effectively isolated by the filter screen 602, thereby effectively shortening the sedimentation time of sewage treatment and enhancing the treatment efficiency.

[0017] In order to further enhance the efficiency of sewage treatment, the device also includes a driving device 2 5 and a mounting platform 4 thereof, wherein the mounting platform 4 is mounted on the piston rod end of the driving device 1 3, and the driving device 2 5 is mounted on the mounting platform 4. The driving device 2 5 can be a motor, and its rotating shaft is connected to the connecting shaft 601. The sedimentation treatment device 6 also includes a stirring blade 605 installed on the mounting ring 604. When in use, the driving device 2 5 can be started to rotate the mounting ring 604, so that the sewage and the flocculant can be fully stirred and mixed, so as to improve the coagulation efficiency, and then the sedimentation treatment can be carried out according to the above-mentioned operating steps.

[0018] In order to enhance the isolation effect of sewage impurities, the sedimentation treatment device 6 also includes a sealing ring 603 that matches the outer ring of the mounting ring 604 with the housing 101. A filter cover is installed on the drain pipe 103, and the setting of the filter cover can prevent impurities from being discharged through the drain pipe 103, thereby ensuring the safety of sewage treatment.
