It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Embodiment 1, according to Figure 1-Figure 8 Provide further explanation.

[0024] The utility model provides a transmission device for sewage treatment, comprising a reactor 1, wherein a support assembly is placed inside the reactor 1, wherein the support assembly is used to support the device and can be adjusted according to the depth of the reactor 1, wherein a transmission assembly is installed on the support assembly, wherein a stirring assembly connected to the support assembly is installed on the transmission assembly, wherein the transmission assembly provides power for the stirring assembly, and the stirring assembly is used to stir the sewage inside the reactor 1 so that the sewage and the reagent are fully mixed.

[0025] Before sewage treatment is required, the operator can first test the acidity and alkalinity of the sewage with pH test paper. If the sewage is acidic, sodium carbonate or sodium hydroxide or limestone or lime can be added to the reagent to neutralize the acidity of the sewage. If the sewage is alkaline, acidic substances such as sulfuric acid, hydrochloric acid or acetic acid can be added to the reagent to neutralize the alkaline sewage so that the sewage reaches an acid-base balance. This method is an embodiment but is not limited to this implementation.

[0026] When it is necessary to stir the sewage, the operator will first adjust the support assembly according to the depth of the reactor 1 so that the support assembly matches the depth of the reactor 1, and then place the support assembly inside the reactor 1, and then start the transmission assembly installed on the support assembly. The transmission assembly can drive the stirring assembly to stir the sewage and chemicals inside the reactor 1. At the same time, the stirring assembly can also stir up and down to fully mix the sewage and chemicals to improve the stirring effect. When the stirring work is completed, the operator can take out the support assembly, and then take out the transmission assembly and the stirring assembly together to avoid the stirring assembly and the transmission assembly from being soaked for a long time and corroded, thereby improving the service life of the device. In addition, during transportation, the height of the support assembly can be reduced to reduce the use of space and improve transportation efficiency.

[0027] As a specific embodiment of the utility model, the support assembly includes a first frame body 2, the first frame body 2 is placed at the bottom of the reactor 1, a groove 4 is opened inside the first frame body 2, a first through hole 5 connected to the groove 4 is opened on the top side wall of the first frame body 2, a first arc groove 7 with a wavy shape is opened on the inner wall of the first frame body 2, a second frame body 3 is slidably connected inside the groove 4, first threaded grooves 9 are spaced apart in the vertical direction on the inner side wall of the second frame body 3, a second arc groove 8 with a wavy shape is opened on the inner wall of the second frame body 3, and a support frame 11 is fixedly connected to the top of the second frame body 3.

[0028] When it is necessary to start treating the sewage, the operator first pulls up the second frame 3 slidably connected to the inside of the groove 4 according to the depth of the reactor 1, and stops pulling the second frame 3 until the overall height of the first frame 2 and the second frame 3 matches the depth of the reactor 1. At this time, the first through hole 5 opened on the top side wall of the first frame 2 and connected to the groove 4 corresponds to one of the first threaded grooves 9 opened on the inner side wall of the second frame 3. The operator fixes the position of the second frame 3 by screwing the screws into the first through hole 5 and the first threaded groove 9 in turn. Through this structure, the transmission assembly and the stirring assembly can be placed in appropriate positions inside the reactor 1 to improve the stirring effect. In addition, the operator can fold up the second frame 3 to reduce the overall space of the device and improve the transportation efficiency of the device.

[0029] As a specific embodiment of the utility model, the transmission assembly includes a motor 12 mounted on a support frame 11, the output end of the motor 12 is fixedly connected to a second transmission shaft 14, a second thread groove 10 is provided on the bottom side wall of the second transmission shaft 14, a first transmission shaft 13 is sleeved on the outside of the second transmission shaft 14, and a second through hole 6 is spaced apart on the first transmission shaft 13.

[0030] When the sewage needs to be stirred, the operator can pull up and down the first transmission shaft 13 that is slidably connected to the outside of the second transmission shaft 14 according to the depth of the reactor 1, so that the overall length of the first transmission shaft 13 and the second transmission shaft 14 is adapted to the depth of the reactor 1, and then when the motor 12 drives the second transmission shaft 14 and the first transmission shaft 13 to rotate, the stirring effect of the sewage can be improved. When the length adjustment of the first transmission shaft 13 and the second transmission shaft 14 is completed, the second thread opened on the side wall of the bottom of the transmission shaft corresponds to one of the second through holes 6 opened on the first transmission shaft 13, and then the screw is screwed into the second through hole 6 and the second thread groove 10 in turn until it is screwed in, thereby fixing the position of the first transmission shaft 13 to prevent the first transmission shaft 13 from being displaced. Here, the motor 12 adopts an AC speed regulating motor, and then the output power of the motor 12 can be adjusted according to the amount of sewage inside the reactor 1, thereby achieving energy-saving effects, reducing power consumption, and reducing costs.

[0031] As a specific embodiment of the present utility model, the stirring assembly includes a first sleeve 15 rotatably connected to the first transmission shaft 13 at one end, a first stirring rod 17 is slidably connected inside the first sleeve 15, a first stirring rod 17 is fixedly connected to the end of the first stirring rod 17 away from the first sleeve 15, the first rubber ball 19 is slidably connected inside the first arc groove 7, a second sleeve 16 arranged above the first sleeve 15 is rotatably connected to the second transmission shaft 14, a second stirring rod 18 is slidably connected inside the second sleeve 16, the second stirring rod 18 is fixedly connected to the end of the second stirring rod 18 away from the second sleeve 16, and the second rubber ball 20 is slidably connected inside the second arc groove 8.

[0032] The diameter of the first rubber ball 19 is larger than the opening diameter of the first arc-shaped groove 7 , and the diameter of the second rubber ball 20 is larger than the opening diameter of the second arc-shaped groove 8 .

[0033] The first arc-shaped groove 7 and the second arc-shaped groove 8 have opposite trajectories.

[0034] After the support assembly and the transmission assembly are adjusted, since one end of the first stirring rod 17 is slidably connected to the inside of the first sleeve 15 and the other end is fixedly connected to the first rubber ball 19, and the first rubber ball 19 is elastic, the operator can insert the first rubber ball 19 into the first arc groove 7 opened on the inner wall of the first frame 2, and the opening diameter of the first arc groove 7 is smaller than the diameter of the first rubber ball 19, so that the first rubber ball 19 cannot slide out from the inside of the first arc groove 7. Similarly, the second rubber ball 20 cannot slide out from the inside of the second arc groove 8. Since the first arc groove 7 is wavy, during the rotation of the first transmission shaft 13, the first sleeve 15 connected to the first transmission shaft 13 is driven to swing up and down. The up and down swinging of the first sleeve 15 can drive the first stirring rod 17 slidably connected to the inside of the first sleeve 15 to move up and down, thereby improving the stirring effect of the first sleeve 15 and the first stirring rod 17 on the sewage. The sewage and the reagent in the lower half of the reactor 1 are fully mixed. Similarly, the second sleeve 16 and the second stirring rod 18 can also swing up and down to improve the stirring effect on the sewage, so that the sewage and the reagent in the upper half of the reactor 1 are fully mixed; in addition, by setting the trajectories of the first arc groove 7 and the second arc groove 8 oppositely, when the first rubber ball 19 moves from the lowest point to the highest point in the same vertical direction, the second rubber ball 20 moves from the highest point to the lowest point, and then the first stirring rod 17 can drive the sewage in the lower half upward, and the second stirring rod 18 can drive the sewage in the upper half downward, so that the sewage in the upper and lower parts is fully mixed, and the stirring effect is further improved; in addition, by setting the corners of the first frame 2 and the second frame 3 to be arc-shaped, the difficulty of moving the first rubber ball 19 and the second rubber ball 20 through the corner can be reduced, and the situation where the first rubber ball 19 and the second rubber ball 20 cannot move can be avoided.

[0035] Working principle: When sewage needs to be treated, the operator first pulls the second frame body 3 upward according to the depth of the reactor 1, and stops pulling the second frame body 3 until the overall height of the first frame body 2 and the second frame body 3 matches the depth of the reactor 1. At this time, the first through hole 5 corresponds to one of the first thread grooves 9 on the inner wall of the second frame body 3. The operator fixes the position of the second frame body 3 by screwing the screws into the first through hole 5 and the first thread groove 9 in turn. Then, the operator can pull the first transmission shaft 13 up and down according to the depth of the reactor 1, so that the overall length of the first transmission shaft 13 and the second transmission shaft 14 match the depth of the reactor 1. At this time, the second thread corresponds to one of the second through holes 6 on the first transmission shaft 13. Then, the screws are screwed into the second through hole 6 and the second thread groove 10 in turn until they are screwed in, thereby fixing the position of the first transmission shaft 13, and then the motor 1 fixedly mounted on the support frame 11 is turned on. 2. The motor 12 rotates to drive the second transmission shaft 14 and the first transmission shaft 13 to rotate, the first transmission shaft 13 drives the first sleeve 15 to rotate, the first sleeve 15 drives the first stirring rod 17 to rotate, the first stirring rod 17 and the first sleeve 15 rotate and swing up and down along the first arc groove 7, and continuously stir the sewage and the reagent in the lower half of the reactor 1 up and down, the second transmission shaft 14 drives the second sleeve 16 to rotate, the second sleeve 16 drives the second stirring rod 18 to rotate, the second sleeve 16 and the second stirring rod 18 rotate and swing up and down along the second arc groove 8, and stir the sewage and the reagent in the upper half of the reactor 1 up and down, when the first stirring rod 17 and the first sleeve 15 move upward, the second stirring rod 18 and the second sleeve 16 move downward, and then the sewage in the upper half of the reactor 1 moves downward, and the sewage in the lower half of the reactor 1 moves downward, so that the sewage impacts each other and improves the mixing effect of the sewage and the reagent.
