[0025] See also Figure 2 , Figure 3 and Figure 4 The outer ring at the bottom of the auxiliary ring 205 is penetrated by a fixing bolt 206, the surface of the fixing bolt 206 is threadedly connected to the connection of the fixing block 201, and the inner ring of the auxiliary ring 205 is fixedly installed with a hollow sleeve 204;

[0027] The top of the inner sleeve 7 and the bottom of the hollow sleeve 204 are both fixedly connected with support blocks. The outer ring of the inner sleeve 7 is fixedly connected to the inner wall of the nozzle housing 1 through the support blocks, and the outer ring of the hollow sleeve 204 is fixedly connected to the inner ring of the auxiliary ring 205 through the support blocks. The existence of the support blocks can stably connect the inner sleeve 7 with the nozzle housing 1, and the hollow sleeve 204 with the auxiliary ring 205 while satisfying the normal circulation of gas or liquid.
[0028] The air inlet flange 3 is arranged obliquely and connected to an external air pump for introducing gas, and the liquid inlet flange 4 is connected to an external infusion pump for introducing sulfuric acid liquid;
[0029] The outer ring of the hollow sleeve 204 is in sliding contact with the inner wall of the liquid passage groove 12 and is sealed;
[0030] By providing the fixing block 201, the auxiliary ring 205 and the fixing bolts 206, the bolt installation function can be achieved. With the cooperation of the fixing bolts 206, the auxiliary ring 205 can be stably installed on the bottom of the fixing block 201.
[0031] By providing the connecting hole 202 and the intersection hole 11, the liquid-passing groove 12 and the venting groove 8 can be in a connected state when the two are aligned, and the liquid-passing groove 12 and the venting groove 8 can be in a disconnected state when the two are misaligned.
[0032] By setting the elastic rubber ring 203, it can play the role of elastic support, and can provide elastic support force for the auxiliary ring 205 in the installed state to prevent the fixing bolt 206 from rotating at will. By setting the air guide flange 3 and the liquid guide flange 4, the gas and liquid introduction requirements can be met respectively;
[0033] By providing the sealing cover 5, the top of the nozzle housing 1 can be sealed and covered in the installed state, and the impurities intercepted in the bearing sleeve 605 can be conveniently cleaned in a centralized manner in the detached state. By providing the windmill blades 601 and the inclined injection holes 10, the inclined injection holes 10 can guide the liquid to flow in an inclined manner, so that the liquid injected in an inclined manner generates an impact force on the windmill blades 601, so that the windmill blades 601 rotate naturally.
[0034] By providing the elastic cleaning brush 602, it can rotate along with the positioning shaft 603, and in the rotating state, the purpose of cleaning the screening net 604 can be achieved. By providing the positioning shaft 603, it can be movably installed on the screening net 604 to ensure its own rotation stability. By providing the screening net 604, the liquid flowing through can be filtered.
[0035] By providing the bearing sleeve 605, the filtered impurities can be temporarily collected and stored, which is convenient for subsequent staff to clean up. By providing the ventilation groove 8 and the liquid groove 12, the gas and liquid can be transmitted and guided respectively. By providing the spiral groove 9, the injected gas can be spirally guided so that the gas can rotate.
[0036] In actual application, when only in vitro mixing is required, the distance between the fixed block 201 and the auxiliary ring 205 is adjusted under the elastic support of the elastic rubber ring 203, so that the connecting hole 202 and the intersection hole 11 are in a misaligned state. At this time, the liquid and gas cannot be gathered in the nozzle shell 1; when only in vivo mixing is required, a sealing plug is fixedly installed at the bottom center of the hollow sleeve 204, and the liquid cannot be discharged through the hollow sleeve 204.
[0037] When in use, all components are in the initial installation state. With the assistance of an external air pump, the gas is introduced into the ventilation groove 8 from the air guide flange 3. With the assistance of the spiral groove 9, the gas has rotation. With the assistance of an external infusion pump, the sulfuric acid liquid is introduced into the liquid guide flange 4 from the liquid guide flange 4. Under the inclined guidance of the injection inclined hole 10, the inclined liquid flow is ejected to the windmill blade 601, so that the windmill blade 601 rotates, driving the positioning shaft 603 and the elastic cleaning brush 602 to rotate. At the same time, the sulfuric acid liquid naturally enters the liquid passage groove 12 through the screening net 604, and the rotating elastic cleaning brush 602 ensures the permeability of the surface of the screening net 604. The liquid transmitted through the liquid passage groove 12 enters the hollow sleeve 204. At this time, the liquid is differentiated, and a small amount of liquid flows into the ventilation groove 8 from the connecting hole 202 and the intersection hole 11, and is mixed in the body by the flowing rotating gas, while most of the gas is directly discharged from the hollow sleeve 204 and mixed in vitro with the synchronously discharged gas, so that the overall mixing effect is better.
[0038] In summary: the new two-stage anti-clogging vortex nozzle in the production process of enhanced superphosphate solves the problem that the nozzle cannot have the function of anti-clogging protection while filtering and cannot have the function of in vivo and in vitro mixing. In actual use, different types of nozzles need to be replaced according to different needs, which is cumbersome to operate.
