[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0031] Reference Figs. 1-5The utility model discloses a sewage stirring mixing device, and the device comprises a sewage pool 1, and the sewage pool 1 can be a circular pool or a rectangular pool. A plurality of anti-deposition components 2 are arranged on the side wall of the sewage pool 1, and a stirring piece 3 is arranged in the sewage pool 1; the stirring piece 3 can stir the sewage in the sewage pool 1.

[0032] The anti-deposition component 2 comprises a floating block 21 and a moving block 28 connected with the floating block 21; the floating block 21 is arranged on the water surface of the sewage, and the density of the floating block 21 is less than or equal to the density of the sewage; the floating block 21 floats up and down with the fluctuation of the sewage; the moving block 28 is arranged at the connection between the bottom of the sewage pool 1 and the side wall of the sewage pool 1; the density of the moving block 28 is greater than the density of the sewage; when the floating block 21 floats up and down, the moving block 28 can be driven to move close to or away from the side wall of the sewage pool 1.

[0033] In the specific application, the density of the floating block 21 is slightly less than the density of the sewage; at this time, the floating block 21 is greatly affected by the sewage, and the fluctuation of the sewage can make the floating block 21 float violently. The moving block 28 is arranged at the connection between the bottom of the sewage pool 1 and the side wall, i.e. the corner; the violent floating of the floating block 21 can drive the moving block 28 to move, so as to prevent the accumulation of sludge. The utility model converts the fluctuation of the sewage water surface into disturbance at the corner of the sewage pool 1, makes up for the deficiency that the stirring paddle cannot stir the corner, and enhances the overall stirring effect of the sewage pool 1.

[0034] In one embodiment, the floating block 21 is sequentially connected with the moving block 28 through a hydraulic piece 24 and a transmission rod 25; the hydraulic piece 24 can amplify the force of the floating block 21 to drive the moving block 28 to move. By arranging the hydraulic piece 24, the force of the floating block 21 can be amplified to drive the moving block 28 to move in a larger range, so as to enhance the disturbance effect of the moving block 28.

[0035] In one embodiment, the floating block 21 is cuboid, and a first fixed frame 22 is sleeved on the outer side of the floating block 21, so that the floating block 21 can only move in the vertical direction, and the end of the first fixed frame 22 away from the floating block 21 is fixed on the side wall of the sewage pool 1. By arranging the first fixed frame 22, a square hole is arranged on the first fixed frame 22, and the square hole can accommodate the floating block 21, so that the floating block 21 can be effectively limited in the square hole and can only move in the vertical direction, thereby facilitating the accurate transmission of the force at a specific angle to the hydraulic component 24, improving the transmission efficiency of the force, and preventing damage to the hydraulic component 24 by force in other directions. In actual application, a limiting structure can be arranged in the square hole, or the two ends of the floating block 21 can be extended radially outward, so as to prevent the floating block 21 from falling off the first fixed frame 22; a cavity capable of containing liquid can be arranged on the floating block 21, so as to adapt to sewage with different densities; and a plurality of rolling balls can be arranged on the hole wall of the square hole, so as to reduce the friction and enable the floating block 21 to float up and down more smoothly.

[0036] In one embodiment, the same side wall of the transmission rod 25 is hingedly connected with the hydraulic component 24 and a third fixed frame 26, respectively, and the end of the third fixed frame 26 away from the transmission rod 25 is fixed on the side wall of the sewage pool 1. The hydraulic component 24 is close to the top end of the transmission rod 25. The third fixed frame 26 is close to the bottom end of the transmission rod 25. In this embodiment, the top of the transmission rod 25 is pushed, and since the transmission rod 25 is hingedly connected to the third fixed frame 26, the movement track of the bottom end of the transmission rod 25 is arc-shaped, so as to effectively drive the movement of the moving block 28. Referring to the drawings, the hinged point of the hydraulic component 24 relative to the hinged point of the third fixed frame 26 is closer to the center of the sewage pool 1, and the transmission rod 25 has an angle with the side wall of the sewage pool 1 in the vertical direction.

[0037] In one embodiment, the hydraulic component 24 is fixed on the second fixed frame 23, and the end of the second fixed frame 23 away from the hydraulic component 24 is fixed on the side wall of the sewage pool 1. The hydraulic component 24 comprises a first hydraulic cylinder 242 and a second hydraulic cylinder 243 arranged in sequence in the vertical direction, the first hydraulic cylinder 242 is arranged vertically, and the second hydraulic cylinder 243 is arranged obliquely downward. The first hydraulic cylinder 242 is provided with a first hydraulic rod 241, the first hydraulic rod 241 extends upward, and the top end is fixedly connected with the bottom end of the floating block 21.

Preferably, the volume of the first hydraulic cylinder 242 is smaller than the volume of the second hydraulic cylinder 243. Specifically, the area of the piston on the first hydraulic rod 241 is smaller than the area of the piston on the second hydraulic rod 244.

[0038] In the embodiment, the first hydraulic cylinder 242 and the second hydraulic cylinder 243 are arranged to have different directions, and the purpose is to accurately transmit the floating force of the floating block 21 in the vertical direction to the transmission rod 25, so that the transmission rod 25 swings and drives the moving block 28 to move. By arranging the first hydraulic cylinder 242 and the second hydraulic cylinder 243 to have different volumes, according to Pascal's law, the first hydraulic cylinder 242 and the second hydraulic cylinder 243 are connected, and the force input to the first hydraulic cylinder 242 can be amplified through the second hydraulic cylinder 243 and then output, so as to more effectively drive the moving block 28.

[0039] In one specific embodiment, the bottom end of the transmission rod 25 is fixedly provided with an arc-shaped rack 27, the upper surface of the moving block 28 is provided with a rack, and the arc-shaped rack 27 is engaged with the rack. Among them, the arc-shaped rack 27 is to bend the existing rack into an arc shape, and a conventional gear can also be used instead of the arc-shaped rack 27. According to actual needs, a flexible sealing cover can be arranged at the rack position and outside the arc-shaped rack 27 to prevent silt from blocking.
