Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a domestic sewage dephosphorization device. Background Art

[0002] Biological phosphorus removal from sewage mainly utilizes the role of phosphorus-accumulating bacteria in releasing phosphorus under anaerobic conditions and accumulating phosphorus under aerobic conditions. Phosphorus removal from sewage includes two necessary processes: first, converting soluble phosphorus-containing substances in sewage into insoluble granular form, and then removing granular solids to achieve the purpose of phosphorus removal from sewage.

[0003] The existing treatment device usually discharges domestic sewage into a sewage treatment tank, pours in the phosphorus removal powder, and then drives the sewage and the phosphorus removal powder to be fully mixed through a group of mixing structures to perform phosphorus removal work. However, the mixing work is performed by only one group of mixing structures, so the mixing work of the phosphorus removal powder and sewage takes a lot of time. At the same time, the position of the mixing structure cannot be moved, and the mobile mixing work cannot be performed, resulting in a decrease in the working efficiency of the phosphorus removal device.

[0004] According to the announcement number: CN216403870U, a phosphorus removal device for domestic sewage is provided, which belongs to the technical field of sewage treatment equipment. The phosphorus removal device for domestic sewage comprises a shell, a motor is fixedly installed on the upper end of the shell, a rotating rod arranged through the shell is fixedly connected to the output end of the motor, the lower end of the rotating rod extends to the inside of the shell, the rotating rod is rotatably connected to the shell, a scraper is fixedly connected to the lower end of the rotating rod, a fixed plate located on the lower side of the scraper is fixedly connected in the shell, a plurality of first through holes equidistantly arranged are provided on the upper end of the fixed plate, a positioning groove located between the scraper and the fixed plate is provided on the inner wall of the shell, two positioning blocks distributed on the left and right are slidably connected in the positioning groove, a rotating plate adapted to the scraper is fixedly connected between the two positioning blocks, a plurality of second through holes equidistantly arranged are provided on the upper end of the rotating plate, which can realize a more complete mixing of the phosphorus removal powder and the sewage, thereby effectively improving the phosphorus removal effect of the domestic sewage and effectively improving the work efficiency.

[0005] According to the phosphorus removal device introduced above, the mixing work is performed only through a group of mixing structures, so the mixing of the phosphorus removal powder and the sewage takes a lot of time. At the same time, the position of the mixing structure cannot be moved, and the mobile mixing work cannot be performed, resulting in a decrease in the working efficiency of the phosphorus removal device. Therefore, we need to propose a domestic sewage phosphorus removal device. Utility Model Content

[0026] During mixing, start the servo motor 10 to drive the conduction component 11 to rotate. The conduction component 11 simultaneously drives the two groups of rotating rods 12 at the bottom end to rotate, so that the rotating rods 12 drive the stirring rod 13 to mix the sewage and phosphorus removal powder in the phosphorus removal tank 1. At the same time, start the lifting and moving mechanism 9, which can push the rotating rod 12 to move in the phosphorus removal tank 1, change the position of the rotating rod 12 in the phosphorus removal tank 1, thereby improving the mixing speed between the sewage and the phosphorus removal powder, enabling the phosphorus removal device to perform mobile mixing work, and improving the working efficiency of the phosphorus removal device.

[0027] The lifting and moving mechanism 9 includes a first cylinder 91. The first cylinder 91 is fixedly installed at the top of the support frame 8. The piston end of the first cylinder 91 penetrates through the support frame 8 and is fixedly connected to a lifting seat 92. Both ends of the lifting seat 92 are slidably connected to the inner side wall of the support frame 8. A moving component is arranged on the surface of the lifting seat 92. The moving component is fixedly connected to the servo motor 10 through a mounting plate. Starting the first cylinder 91 drives the lifting seat 92 to move, so that the lifting seat 92 can drive the rotation and movement through the moving component, changing the height of the rotating rod 12.

At the positions corresponding to the inner side wall of the phosphorus removal tank 1 on the surface of the limit blocks 18, limit grooves 19 are opened. The surface of the limit blocks 18 is slidably connected with the inner cavity of the limit grooves 19. Through the setting of the filter plate 17, when draining water, the objects generated after phosphorus removal from the sewage are filtered, increasing the phosphorus removal quality of the phosphorus removal device for the sewage. Through the cooperation of the limit grooves 19 and the limit blocks 18, the position of the filter plate 17 is limited, and at the same time, it is convenient to disassemble and assemble during maintenance, facilitating the subsequent maintenance work.

[0033] During specific use: Connect the connection port 2 on the phosphorus removal tank 1 to the sewage pipe, inject the sewage into the phosphorus removal tank 1, then pour in the phosphorus removal powder. Start the electric slide table 5 to drive the support frame 8 to move above the phosphorus removal tank 1 through the slide seat 6. Start the first air cylinder 91 to push the lifting seat 92 to move downward, so that the lifting seat 92 drives the rotating rod 12 on the moving seat 95 to insert into the inner cavity of the phosphorus removal tank 1 through the moving frame 93. Start the servo motor 10 to drive the first pulley 111 to rotate. The first pulley 111 drives the second pulley 112 to rotate through belt transmission, so that the two groups of second pulleys 112 drive the rotating rod 12 to rotate synchronously. The two groups of rotating rods 12 drive the stirring rods 13 to mix the sewage at the same time. Then start the second air cylinder 94 to push the moving seat 95 to move, so that the moving seat 95 drives the rotating rod 12 during rotation to move, changing the position of the rotating rod 12 in the phosphorus removal tank 1 to achieve moving mixing. After mixing, move the rotating rod 12 out of the inner cavity of the phosphorus removal tank 1, and the electric slide table 5 drives the support frame 8 to reset, thereby increasing the mixing speed between the sewage and the phosphorus removal powder, enabling the phosphorus removal device to perform moving mixing work and improving the working efficiency of the phosphorus removal device.
