[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a sludge sedimentation device for improving sedimentation effect in wastewater treatment, comprising:

[0022] A mounting frame 1 capable of being mounted on a sedimentation tank;

[0023] The flocculant spraying and mixing component includes a through slot 3 that penetrates the mounting frame 1, and a reciprocating movable block 6 is slidably connected in the through slot 3. The through slot 3 can limit the movable block 6 so that it is not easy to rotate;

[0024] Further explanation of the reciprocating moving block 6: a motor 2 is installed on the mounting frame 1, a reciprocating screw rod 5 is installed at the output end of the motor 2, the other end of the reciprocating screw rod 5 is rotatably connected to the inner wall of the mounting frame 1, the reciprocating screw rod 5 penetrates the moving block 6 and is connected thereto, the motor 2 drives the reciprocating screw rod 5 to rotate, and the moving block 6 can be reciprocated;

[0025] The moving block 6 is penetrated by a vertical tube 7 with a rotatable setting from top to bottom, a rack plate 4 is fixed on the mounting frame 1, a gear 12 is installed on the vertical tube 7, the gear 12 is meshed with the rack plate 4, the moving block 6 moves to drive the vertical tube 7 and the gear 12 to move, the gear 12 moves and rotates on the rack plate 4, so as to realize the rotation of the vertical tube 7, a stirring transverse tube 8 is installed at the bottom of the vertical tube 7, both ends of the stirring transverse tube 8 are blocked, and a plurality of spray holes 14 are distributed in a linear array at the bottom of the stirring transverse tube 8; the rotation of the vertical tube 7 drives the stirring transverse tube 8 to rotate, and a plurality of spray holes 14 are fixed at the bottom of the stirring transverse tube 8; wherein, a plurality of stirring rods can be fixed on the vertical tube 7 to improve the mixing and stirring effect;

[0026] A fan 9 is installed on the mounting frame 1, and a delivery pipe 10 is installed at the air outlet end of the fan 9. The delivery pipe 10 includes a hose and two stainless steel pipes, and the two stainless steel pipes are fixed at both ends of the hose; the delivery pipe 10 is rotatably connected to the vertical pipe 7, and a rotary joint 13 is installed on the vertical pipe 7, and the stainless steel pipe is connected to the rotary joint 13;

[0027] A suction capillary 11 is installed on the delivery pipe 10, and the suction capillary 11 is fixed at the bottom of the stainless steel pipe. The diameter of the suction capillary 11 is smaller than the inner diameter of the stainless steel pipe. A container can be placed on the mounting frame 1, and the container contains flocculant. The suction capillary 11 is located in the container. The fan 9 can work to deliver high-speed air through the delivery pipe 10 to the vertical pipe 7. When the high-speed air passes through the delivery pipe 10, the air flow rate at the upper end of the suction capillary 11 is fast and the pressure is small. The bottom of the suction capillary 11 is The pressure is strong, and a pressure difference is generated, so that the flocculant can be "pressed" into the conveying pipe 10, conveyed to the vertical pipe 7 along with the air, and finally conveyed to the stirring horizontal pipe 8 and sprayed out through the spray hole 14. The air and flocculant are sprayed out through the rotating and moving stirring horizontal pipe 8 and sprayed into the water. The flocculant is sprayed into the water in a spiral shape, so that the flocculant and the wastewater can be mixed. The flocculant and the wastewater can be stirred by the stirring horizontal pipe 8, and the sprayed air also has the effect of mixing the flocculant and the wastewater.
