Technical Field

[0001] The utility model relates to the technical field of plug-flow stirring in sewage regulating tanks, in particular to a novel plug-flow stirring device for sewage regulating tanks. Background Art

[0002] Since there is a lot of sewage sludge in the regulating pond, if it is not cleaned for a long time, it will pollute the regulating pond and affect its normal operation. Now it is regularly sucked out by sewage suction trucks, but due to the long sedimentation time of sludge, especially in the corners and dead corners of the regulating pond, the sludge density is high, and it is difficult to clean it using sewage suction trucks.

[0003] In summary, the prior art has the following disadvantages:

[0004] 1. There is a lot of sludge at the bottom of the sewage regulating tank, and it accumulates in dead corners.

[0005] 2. Sludge in dead corners accumulates and hardens over the years, making it difficult to extract using a sewage suction truck. Utility Model Content

[0006] The utility model aims to solve the problem that there is a lot of sludge at the bottom of the sewage regulating tank, which accumulates in dead corners and the sludge in the dead corners accumulates and hardens all the year round, making it difficult to extract with a sewage suction truck. A new type of plug flow stirring device for the sewage regulating tank is proposed.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A novel plug-flow stirring device for a sewage regulating tank is designed, comprising a motor and a fixed frame, a reducer is installed on the upper right part of the fixed frame, the output shaft of the motor is connected to the coupling through the reducer, a transmission shaft is fixedly connected to the output end of the coupling, the end of the transmission shaft is rotationally connected to the main shaft of a blade through the internal steering structure of a steering box, a fixing rod is fixedly connected to one side of the outer wall of the steering box, the upper part of the outer wall of the fixing rod is fixedly connected to the fixed frame through a frame, and a guide cover is distributed on the outside of the blade.

[0009] Preferably, the motor is located on the upper right side of the fixing frame, and a distribution box is installed above the fixing frame.

[0010] Preferably, the distribution box provides control circuits and power for the motor.

[0011] Preferably, the stirring blade diameter of the paddle is 1000 mm.

[0012] Preferably, the stirring blade of the paddle is installed at a depth of 500 mm from the bottom of the regulating tank.

[0013] The utility model proposes a novel plug flow stirring device for a sewage regulating tank, which has the following beneficial effects:

[0014] Through the coordination among the motor, transmission shaft, steering box, paddles, reducer and coupling, the output shaft of the control motor drives the transmission shaft to rotate through the reducer and coupling in turn. Finally, the transmission shaft drives the paddles to rotate through the internal steering structure of the steering box. When the paddles rotate, the sewage in the regulating tank is discharged along the guide holes of the guide cover, so that the discharged sewage is more uniform, and the sludge accumulated in the corners of the regulating tank is also stirred up, which effectively realizes the regular stirring of the bottom of the sewage regulating tank, making it difficult for sludge to accumulate. At the same time, due to the uniform distribution of sewage pushed by the paddles, there is no dead corner at the bottom of the regulating tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] Refer to the attached Figure 1-3 : In the present embodiment, a new type of plug-flow stirring device for a sewage regulating tank comprises a motor 1 and a fixed frame 10, a reducer 2 is installed on the upper right part of the fixed frame 10, the output shaft of the motor 1 is connected to the coupling 3 through the reducer 2, the output end of the coupling 3 is fixedly connected to a transmission shaft 5, the end of the transmission shaft 5 is rotationally connected to the main shaft of the blade 7 through the internal steering structure of the steering box 6, a fixing rod 9 is fixedly connected to one side of the outer wall of the steering box 6, the upper part of the outer wall of the fixing rod 9 is fixedly connected to the fixed frame 10 through the frame 4, the motor 1 is located on the upper right side of the fixed frame 10, a guide cover 8 is distributed on the outer side of the blade 7, and a distribution box 11 is installed above the fixed frame 10, and the distribution box 11 provides a control circuit and power for the motor 1;

[0022] According to the size of the sewage regulating tank, select the following types of plug flow stirring device:

[0023] 1. Motor 1 has a power of 3kw. The model of the motor can be determined according to the specific usage.

[0024] 2. The diameter of the stirring blade of the paddle 7 is 1000 mm.

[0025] 3. The installation depth of the stirring blade of the paddle 7 is 500mm from the bottom and can be adjusted according to actual conditions.

[0026] 4. The deflector 8 can be replaced.

[0027] Through the coordination among the motor 1, the transmission shaft 5, the steering box 6, the paddle 7, the reducer 2 and the coupling 3, the output shaft of the control motor 1 drives the transmission shaft 5 to rotate through the reducer 2 and the coupling 3 in turn. Finally, the transmission shaft 5 drives the paddle 7 to rotate through the internal steering structure of the steering box 6. When the paddle 7 rotates, the sewage in the regulating tank is discharged along the guide hole of the guide cover 8, so that the discharged sewage is more uniform, and the sludge accumulated in the corners of the regulating tank is also stirred up, which effectively realizes the regular stirring of the bottom of the sewage regulating tank, making it difficult for the sludge to accumulate. At the same time, due to the uniform distribution of the sewage pushed by the paddle 7, there is no dead corner at the bottom of the regulating tank.

[0029] When this new type of plug-flow stirring device for sewage regulating tank is needed, first, install the equipment according to the figure, then control the motor 1 to start through the distribution box 11, so that the output shaft of the motor 1 drives the transmission shaft 5 to rotate through the reducer 2 and the coupling 3 in turn, and finally, the transmission shaft 5 drives the paddle 7 to rotate through the internal steering structure of the steering box 6. When the paddle 7 rotates, the sewage in the regulating tank is discharged along the guide hole of the guide cover 8, so that the discharged sewage is more uniform, and the sludge accumulated in the corners of the regulating tank is also stirred up, which effectively realizes the regular stirring of the bottom of the sewage regulating tank, making it difficult for sludge to accumulate. At the same time, due to the uniform distribution of sewage pushed by the paddle, there is no dead corner at the bottom of the regulating tank.
