Different reagents can be added to the mixing chamber 101 of the tank body 1 through the multiple feeding ports 41 to improve the efficiency of reagent addition. A discharge valve 104 is installed at the bottom of the tank body 1. The treated sewage can be discharged to a designated location by opening the discharge valve 104. A plurality of supporting legs 105 are connected to the bottom of the tank body 1 and around the discharge valve 104. The plurality of supporting legs 105 are distributed in a circular array and are used to lift the tank body 1 to facilitate the installation of the discharge valve 104 and perform other related operations.

[0028] like Figure 1-Figure 3As shown, a plurality of feeding augers 5 are installed on the top of the cover plate 4, and the feeding augers 5 correspond to the feeding ports 41 one by one. Specifically, the outlet end of the feeding augers 5 is connected to the feeding ports 41 correspondingly, and the two are connected by a soft connection. The feeding augers 5 are controlled by a variable frequency motor, which can realize the adjustment and control of the dosage of different types of drugs and avoid waste of drugs.

[0029] like Figure 2-Figure 7 As shown, a receiving tray 3 is installed above the blanking tray 2, and there is a small gap or no gap between the receiving tray 3 and the blanking tray 2. The receiving tray 3 can rotate relative to the tank body 1, and the rotation of the receiving tray 3 is driven by a power mechanism. Specifically, the power mechanism includes a vertical motor 6 and a power shaft 7. The vertical motor 6 is installed at the top center of the cover plate 4, and the power shaft 7 is located in the tank body 1. The upper end of the power shaft 7 penetrates the cover plate 4 upward and is connected to the output end of the vertical motor 6. The power shaft 7 is driven by the vertical motor 6 to rotate, and the lower end of the power shaft 7 penetrates the receiving tray 3 and the blanking tray 2 downward in turn and extends into the processing chamber 102, and a second driving gear 11 is fixedly installed at this end. The power shaft 7 is connected to the blanking tray 2 through a bearing seat at the position where the power shaft 7 passes through the blanking tray 2, and is located on the blanking tray 2. A transmission shaft 8 is installed on one side of the power shaft 7, and the transmission shaft 8 is connected to the blanking tray 2 through a bearing. A first driving gear 10 is fixedly installed on one end of the transmission shaft 8, and the first driving gear 10 is meshed with the second driving gear 11. A driving gear 9 is fixedly installed on the other end of the transmission shaft 8. The driving gear 9 adopts an incomplete gear, and an inner gear ring 32 is processed on the receiving tray 3. The driving gear 9 is meshed with the inner gear ring 32. The vertical motor 6 drives the power shaft 7 and the second driving gear 11 installed on the power shaft 7 to rotate, and the second driving gear 11 is meshed with the first driving gear 10 to drive the transmission shaft 8 and the driving gear 9 to rotate. Since the driving gear 9 adopts an incomplete gear, the driving gear 9 is meshed with the inner gear ring 32 to drive the receiving tray 3 to achieve intermittent rotation;

[0030] A plurality of first drop holes 31 are processed in a uniform circular array on the receiving tray 3, and a plurality of second drop holes 21 are processed in a uniform circular array on the drop tray 2. The number and interval of the second drop holes 21 are multiples of the number and interval of the first drop holes 31, and the first drop holes 31 and the second drop holes 21 can be switched between corresponding connection and misalignment by cooperating with the incomplete gear when the receiving tray 3 rotates intermittently. When the first drop hole 31 and the second drop hole 21 are correspondingly connected, the medicine drops from the mixing chamber 101 to the processing chamber 102 through the first drop hole 31 and the second drop hole 21. When the first drop hole 31 and the second drop hole 21 are misaligned, the mixing chamber 101 and the processing chamber 102 are isolated, so that the medicine is added in a dispersed manner and is prevented from being piled up in the same position.

[0031] A circle of annular track 103 is processed on the inner wall of the tank body 1, and a plurality of rollers 33 are installed on the circumferential surface of the receiving tray 3. The plurality of rollers 33 are distributed in a circular array. The rollers 33 are in rolling contact with the annular track 103 to support the receiving tray 3 and reduce the friction of the receiving tray 3 during rotation, so that the receiving tray 3 can rotate flexibly.

[0032] like Figure 2 and Figure 3 As shown, a first blade 12 is installed at the portion of the power shaft 7 located above the receiving plate 3, which is used to stir and mix the multiple medicines fed into the mixing chamber 101 by the feeding auger 5 to improve the uniformity of the medicine mixing. A second blade 13 is installed at the lower end of the power shaft 7. The power shaft 7 drives the second blade 13 to rotate, so as to further break up the medicines dropped from the first drop hole 31 and the second drop hole 21, so that the medicines are scattered and sprinkled into the sewage, thereby improving the uniformity of the dispersion of the medicines.

[0033] like Figure 2 and Figure 3 As shown, the stirring assembly includes a driving motor 14 and a stirring shaft 15, the driving motor 14 is installed on the outside of the tank body 1, and the stirring shaft 15 is rotatably installed inside the tank body 1, one end of the stirring shaft 15 passes through the tank body 1 and is drivingly connected to the output shaft of the driving motor 14, and the other end of the stirring shaft 15 passes through the tank body 1 and is connected to the tank body 1 through a bearing seat, and a third blade 16 is installed on the stirring shaft 15 located inside the tank body 1, which is used to stir the sewage, improve the fusion effect of the agent and the sewage, and speed up the treatment of the sewage;

[0034] A liquid level meter 17 and a liquid inlet pipe 18 are installed on the tank body 1. The liquid level meter 17 and the liquid inlet pipe 18 are both connected to the interior of the treatment chamber 102. The sewage to be treated is added into the treatment chamber 102 through the liquid inlet pipe 18, and the amount of sewage in the tank body 1 can be observed through the liquid level meter 17 to prevent excessive water from being injected into the tank body 1.

[0035] The working principle of the utility model is:

[0036] When in use, different agents are added to different feeding screws 5 respectively, and the sewage to be treated is injected into the treatment chamber 102 of the tank body 1 through the liquid inlet pipe 18, and multiple feeding screws 5 are started respectively. The amount of different agents added to the mixing chamber 101 is controlled by frequency conversion control, and the vertical motor 6 is started. The vertical motor 6 drives the first blade 12 through the power shaft 7 to fully stir and mix the agents in the mixing chamber 101 to improve the mixing degree, and the first driving gear 10 and the second driving gear 11 that are meshed with each other are driven by the power shaft 7, and then the driving gear 9 is driven to rotate through the transmission shaft 8, and the driving gear 9 is meshed with the inner gear ring 32. Since the driving gear 9 is an incomplete gear, the receiving plate 3 is realized. Intermittent rotation, the intermittent rotation of the receiving plate 3 realizes the switching between mutual connection and mutual misalignment of the first drop hole 31 and the second drop hole 21. When the first drop hole 31 and the second drop hole 21 are connected to each other, the mixed medicine falls downward through the first drop hole 31 and the second drop hole 21. In the process of falling, the rotating second blade 13 further breaks up the medicine, so that the medicine is evenly dispersed and falls into the sewage to be treated for mixing. The driving motor 14 is started, and the driving motor 14 drives the stirring shaft 15 to rotate. The third blade 16 stirs the medicine-water mixture in the treatment chamber 102, so that the medicine and the sewage are quickly and fully integrated, thereby improving the efficiency of sewage treatment. The treated sewage is discharged through the discharge valve 104.

[0037] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
