The bottom end of the connecting shaft tube 4 is inserted into the tank body 1. The bottom of the tank body 1 protrudes downward to form a spherical surface. The nozzle 11 is installed on the bottom end of the connecting shaft tube 4 and is fluid-conducted with the connecting shaft tube 4. The nozzle 11 is coaxially arranged with the tank body 1, as shown in FIG. Figure 4 As shown, the liquid outlet of the nozzle 11 is arranged toward the bottom of the tank body 1, and the liquid outlet of the nozzle 11 is arranged to be inclined toward the tangent direction of the connecting shaft tube 4. A medicine storage tank 15 is arranged on one side of the tank body 1. The bottom of the medicine storage tank 15 is fluid-connected with the connecting shaft tube 4 through the medicine supply pipe 17, and the top of the medicine storage tank 15 is fluid-connected with the air pressure pipe 1. By setting the nozzle 11, the nozzle 11 is not only inclined toward the bottom of the tank, but also inclined toward the tangent direction of the connecting shaft tube 4. By introducing compressed air into the medicine storage tank 15, the medicine can be sprayed quickly, so that the medicine can be quickly added to the black liquor, and the medicine and the black liquor can be fully mixed. When the liquid medicine is sprayed, the residual compressed air in the medicine storage tank 15 can continue to be sprayed into the black liquor, and the compressed air is used to enhance the mixing effect.

[0025] like Figure 1-2 As shown, a support frame 2 is fixedly connected to the top of the tank body 1, a fixing plate 3 is fixedly connected to the top of the support frame 2, a connecting shaft tube 4 passes through the fixing plate 3 and slidably cooperates with the fixing plate 3, and a limiting block 9 is fixedly connected to the top of the connecting shaft tube 4.

[0026] like Figure 2 , Figure 3 and Figure 5As shown, a filtering mechanism is installed on the side wall of the connecting shaft tube 4, and the filtering mechanism includes a hinged rod 7 and a filter screen 12. The hinged rod 7 is hinged on the side wall of the connecting shaft tube 4, and more than three hinged rods 7 are arranged in the circumferential direction of the connecting shaft tube 4, and the filter screen 12 is fixedly connected between two adjacent hinged rods 7; a telescopic driving mechanism is fixedly connected to the top of the tank body 1, and the telescopic driving mechanism is drivingly connected to the hinged rod 7, a hinged rod 7 is hinged on the side wall of the connecting shaft tube 4, and more than three hinged rods 7 are arranged in the circumferential direction of the connecting shaft tube 4, and the filter screen 12 is fixedly connected between two adjacent hinged rods 7, and the connecting shaft An annular groove is provided at the position where the hinged rod 7 is installed on the tube 4, and the hinged rod 7 is arranged in the annular groove. A sliding sleeve 5 is slidably fitted on the connecting shaft tube 4, and a pull rod 6 is hinged on the side wall of the sliding sleeve 5. The other end of the pull rod 6 is hinged to the side wall of the hinged rod 7. A limit ring 8 is coaxially fixedly connected to the connecting shaft tube 4, and the limit ring 8 is located between the fixed plate 3 and the sliding sleeve 5. By setting a hinged rod 7 that can be unfolded or folded, the filter screen 12 is driven to unfold from the depth upward. The black liquor rotates under the impetus of the agent and the airflow, and the suspended matter gradually moves toward the rotation center. The suspended matter in the black liquor can be filtered during the unfolding process of the filter screen 12.

[0027] like Figure 2 As shown, a telescopic driving mechanism is fixedly connected to the top of the tank body 1, and the telescopic driving mechanism drives the hinge rod 7 to fold or unfold. The driving end of the telescopic driving mechanism is fixedly connected to the sliding sleeve 5. In this embodiment, the telescopic driving mechanism is a hydraulic cylinder 10, and the cylinder body of the hydraulic cylinder 10 is fixed on the fixed plate 3. The piston rod of the hydraulic cylinder 10 passes through the fixed plate 3 and is fixedly connected to the sliding sleeve 5.

[0028] Working principle: In actual use, black liquor is added into tank 1, and the initial state is as follows Figure 1 As shown, the agent is added into the medicine storage tank 15, and compressed air is supplied into the medicine storage tank 15 through the air pressure pipe 16. Under the push of the compressed air, the agent quickly enters the connecting shaft tube 4 through the medicine supply pipe 17, and is sprayed into the black liquor through the nozzle 11. Under the push of the agent, the black liquor rotates. After the agent is sprayed, the compressed air in the medicine storage tank 15 is sprayed into the black liquor through the nozzle 11 to enhance the mixing effect and at the same time promote the black liquor to rotate faster. Under the action of the bubbles, the suspended matter is driven to rise.

[0029] When filtering is required, the hydraulic cylinder 10 is controlled to contract, first driving the sliding sleeve 5 to rise along the connecting shaft tube 4, and the sliding sleeve 5 pulls the hinged rod 7 to unfold through the pull rod 6, and at the same time drives the filter screen 12 to unfold. The connecting shaft tube 4 will not move upward under the action of its own weight. During the unfolding process, suspended matter and impurities are filtered. The mesh size of the filter screen 12 can be adjusted according to actual needs. Then the sliding sleeve 5 contacts the limiting ring 8, and the hydraulic cylinder 10 continues to contract. The sliding sleeve 5 drives the connecting shaft tube 4 to move upward by pushing the limiting ring 8, so that the hinged rod 7 drives the filter screen 12 to move upward as well, and filtration is achieved until the filter screen 12 is separated from the black liquid surface, and then the impurities on the surface of the filter screen 12 are cleaned.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
