[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: Embodiment 1: The solution disclosed in this embodiment solves the problems existing in the prior art through the following contents, such as Figure 1-Figure 2As shown, it includes a shell 1 and a delivery port 2 arranged at the top thereof, the delivery port 2 is connected to the top of a guide pipe 3 for guiding medicine and sewage, the upper half of the guide pipe 3 is rotatably installed at the center of the top of the shell 1, and the section is connected to a motor installed on the shell 1, wherein the medicine and sewage enter the shell 1 through the bottom end of the guide pipe 3 to participate in the reaction and purify the sewage, and the multiple lower halves of the guide pipe 3 are arranged on a non-coaxial axis with the shell 1, and the guide pipe 3 is driven to rotate by the motor so that the bottom end of the guide pipe 3 revolves around the axis of the shell 1 to improve the self-mixing effect; in the main scheme The reagent and sewage are put into the injection port 2 one after the other, and flow naturally to the upper half of the guide pipe 3. In this process, the fluid generates a diversion effect through the multiple branches of the lower half of the guide pipe 3, and is more or less evenly distributed inside the shell 1 under the diversion effect. At the same time, the motor can be in operation to drive the guide pipe 3 to rotate as a whole in the shell 1. At this time, the diverted fluid is rotated and dispersed again. Then, in the case of a small amount of fluid, such as the reagent, it will be more evenly distributed in the shell 1, so that the subsequent contact and reaction between the sewage and the reagent will be more sufficient.

[0025] The purpose of the scheme disclosed in this embodiment is to further improve the self-mixing effect and the sewage purification effect. Figure 2-Figure 4 As shown, a multi-directional reaction mechanism is also arranged inside the shell 1, wherein the multi-directional reaction mechanism guides the sewage or the medicine to have a multi-directional mixing reaction by the revolution of the lower half of the guide pipe 3, and the multi-directional reaction mechanism comprises a vertical pipe 4 connected to the bottom end of the guide pipe 3, and the bottom end of the vertical pipe 4 is located near the bottom wall of the shell 1, and the interior of the vertical pipe 4 also comprises an auger 5 which rotates following the revolution of the guide pipe 3, and the auger 5 is mounted on a vertical shaft 6, and the vertical shaft 6 is connected to a driving mechanism, wherein the driving mechanism drives the vertical shaft 6 and the rotation of the auger 5 by the revolution of the guide pipe 3, and the driving mechanism comprises a gear 7 and a gear ring 8 fixed in the shell 1 for meshing with the gear 7, and the top end of the vertical shaft 6 rotates through the guide pipe 3 and is connected to the gear 7, and the top of the vertical pipe 4 The half section is also provided with an opening which is initially located above the liquid level in the outer shell 1. When the motor drives the guide tube 3 to rotate, the vertical shaft 6 inside the guide tube 3 located in the eccentric section of the lower half section will synchronously revolve around the axis of the outer shell 1. Therefore, when the gear 7 at the top of the vertical shaft 6 is in a revolving state and is always meshed with the ring gear 8, the gear 7 will also drive the vertical shaft 6 to rotate during this process, so that the auger 5 can synchronously rotate inside the vertical pipe 4, and the rotation direction is related to the direction of the guide tube 3. When the auger 5 is in the normal rotation reverse direction, assuming that the sewage submerges the bottom of the vertical pipe 4 at this time, the rotation of the auger 5 will have an effect of pressing down the water body, and the reversal will have a function of lifting the water body and falling from the opening, cooperating with the revolution of the vertical pipe 4 to achieve a better revolution effect.

[0026] Embodiment 2: The solution disclosed in this embodiment is further expanded on the basis of having a vertical pipe 4. The main problem to be solved is that a large amount of scum and foam generated during the sewage purification reaction will greatly affect the subsequent reaction and purification effect of the sewage. Figure 5-Figure 7 As shown, a defoaming ring 10 is also provided inside the shell 1, and the defoaming ring 10 is slidably nested on the vertical pipe 4, and the inner ring of the ring body is installed with a suction head 11, and the suction head 11 is connected with the pipe 12 through the hollow structure inside the defoaming ring 10, and the lower end face of the defoaming ring 10 is inlaid with a floating ring 13, and the outer end of the soft pipe 12 is connected to the negative pressure or air supply equipment. No matter what state, the defoaming ring 10 is always located above the bottom opening of the vertical pipe 4. Under the rotation drive of multiple vertical pipes 4, the defoaming ring 10 itself will also rotate synchronously, and in the initial stage of fluid delivery, the rotation speed of the vertical pipe 4 is relatively fast, causing the defoaming ring 10 to slowly rise or not rise under the influence of the relative force between the inner wall of the penetration point and the outer wall of the vertical pipe 4, and the liquid level height tends to be stable. When the vertical pipe 4 gradually stops rotating, the defoaming ring 10 will move up relatively quickly along the vertical pipe 4 under the influence of the floating ring 13. In this process, a high-pressure airflow or water flow can be provided toward the suction head 11 through the pipe 12, so as to further promote the reaction rate of the sewage tending to be static. After a certain period of reaction, the foam or scum near the defoaming ring 10, that is, near the liquid surface, can be extracted through the negative pressure device connected to the pipe 12. Although the name of the suction head 11 in this scheme reflects the negative pressure suction effect, it is similar to a conventional nozzle. The two-way conduction feature enables it to achieve both negative pressure adsorption and high-pressure injection. As for how the pipe 12 switches the connection state with the negative pressure or high-pressure device, it will not be elaborated.

[0027] Embodiment 3: The scheme disclosed in this embodiment is mainly used to further improve the mixing effect and increase the sewage reaction purification rate. Figure 8-Figure 9 As shown, a counterweight 9 is eccentrically installed at the bottom end of the vertical shaft 6, wherein the counterweight 9 can be made of magnetic material and is used to absorb metal impurities in sewage. Dispersion plates 14 are installed on the upper and lower surfaces of the counterweight 9. The counterweight 9 is eccentrically installed at the bottom end of the vertical shaft 6 because when the motor is a non-self-locking drive motor, after the motor stops running, the centrifugal force and inertial force generated by the eccentric rotation of the counterweight 9 will continue to drive the vertical shaft 6 to operate for a certain period of time. At the same time, since the surface of the counterweight 9 is installed with a dispersion plate 14, when the agent falls through the vertical pipe 4, it will be effectively hit, broken and dispersed by the dispersion plate 14, thereby increasing the initial contact area and reaction rate between the subsequent sewage and the agent, and improving the purification effect.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
