[0007] A cam is fixedly mounted on the surface of the stirring rod, and an indirect communication mechanism is arranged on the outer side of the cam, and the indirect communication mechanism indirectly feeds high-purity cobalt sulfate through the rotation of the cam;

[0008] A circulation pipeline is installed through the right side of the bottom of the tower body, and a circulation filtering mechanism is arranged at the upper end of the circulation pipeline, and the circulation filtering mechanism extracts high-purity cobalt sulfate at the bottom of the tower body through the circulation pipeline.

[0009] Furthermore, a communication pipe is provided between the tower body and the mixing bin, a spray plate is fixedly installed at the lower end of the communication pipe, and the outer side of the spray plate is fixedly installed on the inner wall of the tower body.

[0010] Furthermore, a valve platform is fixedly installed at the bottom of the tower body, a filling layer is placed on the upper end of the valve platform, and a feed pipeline is installed through the left side of the tower body.

[0011] Furthermore, the indirect connecting mechanism is provided with an extrusion rod, and the middle end of the extrusion rod passes through the bottom of the mixing bin, and the right side of the extrusion rod is inclined, and the right side position of the extrusion rod corresponds to the cam, and a return spring is passed through the middle end of the extrusion rod, and the return spring is fixedly installed between the mixing bin and the extrusion rod.

[0012] Furthermore, a sealing plate is fixedly installed on the left side of the extrusion rod, and a leakage hole is opened inside the right side of the sealing plate, and the leakage hole corresponds to the position of the connecting pipe.

[0013] Furthermore, the circulation filtering mechanism is provided with a pressure pump, and the pressure pump is fixedly installed at the middle end of the circulation pipe, and the upper end of the circulation pipe passes through the upper end of the mixing bin, and a limiting groove is opened inside the mixing bin, and a rotating door is rotatably installed at the upper right end of the mixing bin.

[0014] Furthermore, a filter screen is provided inside the mixing bin, and the filter screen is connected to the limiting groove by sliding connection, and the filter screen is located below the upper end outlet of the circulation pipeline.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. A stirring rod capable of stirring and mixing is provided. When high-purity cobalt sulfate is added to the mixing bin through the injection port, the powdered high-purity cobalt sulfate and water are stirred and mixed by the stirring rod fixedly connected to the upper output end of the dual-axis motor, thereby eliminating the need for manual mixing by the staff, reducing the number of operating steps for the staff, and being more practical;

[0017] Furthermore, the mixed high-purity cobalt sulfate is fed into the spray plate through the connecting pipe, and the spray plate can spray the liquid or gas fed from the feed pipe at the lower end, so that the high-purity cobalt sulfate solution can be mixed with the device to be treated.

At this time, when the cam rotates, the cam squeezes the inclined part of the right end of the extrusion rod. The extruded extrusion rod squeezes the return spring to the left and pushes the sealing plate. The sealing plate moves to the left so that the internal leakage hole can connect the mixing bin and the connecting pipe. When the extrusion rod stops being squeezed by the cam, the extrusion rod can move to the right under the action of the return spring. At the same time, the sealing plate seals the mixing bin and the connecting pipe, which can achieve the effect of indirect connection, which can be conducive to full mixing, avoiding the poor purification effect of excessive high-purity cobalt sulfate added at one time, giving time for reaction, and improving the efficiency of high-purity cobalt sulfate washing;

[0020] Furthermore, a circulation pipeline is provided to save resource consumption. After the gas is washed, the used high-purity cobalt sulfate solution enters the bottom of the tower body. At this time, the high-purity cobalt sulfate solution is extracted by a pressure pump arranged on the surface of the circulation pipeline and sent to the upper right end of the mixing bin. The outlet of the circulation pipeline is located at the upper end of the filter screen. The filter screen filters the high-purity cobalt sulfate solution and is put back into use. Putting it back into use can save resource consumption. At the same time, the filter screen can slide upward along the limit groove. When the rotating door is opened, the filter screen can be conveniently removed for cleaning, thereby improving the convenience of use for the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this example, a stirring rod 6 capable of stirring and mixing is provided. When high-purity cobalt sulfate is added to the mixing bin 2 through the injection port 3, the powdered high-purity cobalt sulfate and water are stirred and mixed through the stirring rod 6 fixedly connected to the output end of the upper end of the dual-axis motor 4, thereby eliminating the need for manual mixing by the staff, reducing the number of operation steps for the staff, and being more practical. The mixed high-purity cobalt sulfate is fed into the spray plate 8 through the connecting pipe 7, and the spray plate 8 can spray the liquid or gas fed from the feed pipe 10 at the lower end, so that the high-purity cobalt sulfate solution can be mixed with the device to be treated, and ... The rotating plate 5 is arranged so that the high-purity cobalt sulfate liquid sprayed by the spray plate 8 can be fully sprinkled inside the tower body 1, and the high-purity cobalt sulfate solution can be fully put into the tower body 1, thereby improving the washing effect of the device. A valve platform 11 is arranged at the bottom of the tower body 1, and a filling layer 9 is placed above the valve platform 11. The inside of the filling layer 9 is an irregular shape, which can divert the gas or liquid to be processed, so that the material to be processed has a larger contact area with the high-purity cobalt sulfate solution, further improving the purification effect. The liquid or gas after purification is discharged through the valve port at the bottom of the valve platform 11;

[0032] Embodiment 2:

[0034] In this example, when the stirring rod 6 rotates, the cam 12 arranged at the bottom of the stirring rod 6 rotates following the rotation of the stirring rod 6. At this time, when the cam 12 rotates, the cam 12 squeezes the inclined portion of the right end of the squeezing rod 13. The squeezed squeezing rod 13 squeezes the return spring 16 to the left while pushing the sealing plate 14. The sealing plate 14 moves to the left so that the internal leak hole 15 can connect the mixing bin 2 and the connecting pipe 7. When the squeezing rod 13 stops being squeezed by the cam 12, the squeezing rod 13 is able to move to the right under the action of the return spring 16. At the same time, the sealing plate 14 seals the mixing bin 2 and the connecting pipe 7, which can achieve the effect of indirect connection, which can be conducive to full mixing, avoiding the poor purification effect of excessive high-purity cobalt sulfate added at one time, giving time for reaction, and improving the efficiency of high-purity cobalt sulfate washing;

[0037] In this example, a circulation pipe 17 is provided to save resource consumption. After the gas is washed, the used high-purity cobalt sulfate solution enters the bottom of the tower body 1. At this time, the high-purity cobalt sulfate solution is extracted by the pressure pump 18 arranged on the surface of the circulation pipe 17 and sent to the upper right end of the mixing bin 2. The outlet of the circulation pipe 17 is located at the upper end of the filter screen 19. The filter screen 19 filters the high-purity cobalt sulfate solution and puts it back into use.
