[0029] The lifting assembly includes a reciprocating screw rod 406, a connecting rod 407 and a stirring rod 409;

[0031] Please refer to Figure 3A feed port 2 is fixedly connected to the top of the medicine tank 1 , and a discharge port 3 is fixedly connected to the bottom of the outer wall of the medicine tank 1 .

[0032] In this embodiment, various liquid medicines such as flocculants, scale inhibitors, corrosion inhibitors, demulsifiers, etc. are poured into the medicine tank 1 through the feed port 2, and when the liquid medicines are stirred, they can be discharged to the outside through the discharge port 3.

[0033] Please refer to Figure 3 The outer sides of the first synchronous wheel 403 and the second synchronous wheel 404 are meshed with the tooth grooves on the inner side of the synchronous belt 405, and the rotating first synchronous wheel 403 is used to drive the second synchronous wheel 404 to rotate synchronously through the synchronous belt 405.

[0034] In this embodiment, because the outer sides of the first synchronous wheel 403 and the second synchronous wheel 404 are meshed with the tooth grooves on the inner side of the synchronous belt 405 , the rotating first synchronous wheel 403 drives the second synchronous wheel 404 to rotate synchronously through the synchronous belt 405 .

[0036] In this embodiment, the stirring rod 409 moves back and forth toward the outside and inside of the rotating rod 408, and the stirring rod 409 in the lifting state stretches and resets the spring 4010, so that the spring 4010 in the telescopic state assists the stirring rod 409 to move up and down.

[0038] In this embodiment, the stirring blades 5 that rotate synchronously and move up and down are used to evenly stir the liquid medicine in the medicine tank 1, thereby effectively improving the quality of the finished liquid medicine after stirring.

[0039] Please refer to Figure 2 A plurality of through holes 6 are provided inside the stirring blade 5 , and the through holes 6 are used to reduce the resistance generated by the stirring blade 5 when stirring the liquid medicine.

[0040] In this embodiment: because the stirring blade 5 that rotates synchronously and moves up and down will generate greater resistance when stirring the medicine liquid, at this time, through the multiple through holes 6 opened on the stirring blade 5, the medicine liquid can flow through the through holes 6, so that the through holes 6 reduce the resistance generated by the stirring blade 5 when stirring the medicine liquid.

[0041] Working principle: when it is necessary to add medicine to the gas wellhead, firstly, various liquid medicines must be uniformly stirred, and various liquid medicines such as flocculants, scale inhibitors, corrosion inhibitors, demulsifiers, etc. must be poured into the medicine tank 1 through the feed port 2. At this time, the motor 401 is powered on and operated, so that the output shaft of the running motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the first synchronous wheel 403 and the reciprocating screw 406 to rotate at the same time. Because the outer sides of the first synchronous wheel 403 and the second synchronous wheel 404 are meshed with the tooth grooves on the inner side of the synchronous belt 405, the rotating first synchronous wheel 403 drives the second synchronous wheel 404 to rotate synchronously through the synchronous belt 405, and the rotating second synchronous wheel 404 drives the rotating rod 408 to rotate, and the rotating rod 408 drives the stirring rod 409 to rotate, so that the rotating stirring rod 409 drives the multiple stirring blades 5 to rotate;

[0042] At the same time, the reciprocating screw rod 406 in the rotating state drives the connecting rod 407 to move up and down along its external thread track, and the connecting rod 407 drives the stirring rod 409 to move up and down, and moves the stirring rod 409 to the outside and inside of the rotating rod 408 back and forth, and the stirring rod 409 in the lifting and moving state stretches and resets the spring 4010, so that the spring 4010 in the telescopic state assists the stirring rod 409 to move up and down, and the stirring rod 409 drives multiple stirring blades 5 to move up and down, so that the stirring blades 5 that rotate synchronously and move up and down will concentrate and evenly stir the medicine liquid located above and below the inside of the medicine tank 1, effectively improving the quality of the finished product of the stirred medicine liquid, and when the stirring of the medicine liquid is completed, it can be discharged to the outside through the discharge port 3;

[0043] It should be noted that: when the stirring blade 5 that rotates synchronously and moves up and down drives the drug liquid to stir, a large resistance will be generated. At this time, through the multiple through holes 6 opened on the stirring blade 5, the drug liquid can flow through the through holes 6, so that the through holes 6 reduce the resistance generated by the stirring blade 5 when stirring the drug liquid.

[0044] 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.
