Description

Technical Field

[0001] The utility model relates to the field of stirring equipment, in particular to a stirrer with an adjustable inclination angle of a stirring rod. Background Art

[0002] Agitators are devices that force convection and uniform mixing of liquid and gaseous media. The type, size and speed of the agitator affect the distribution of stirring power between the overall flow and turbulent pulsation. There are many types of agitators, and the most commonly used ones are turbine agitators and propeller agitators. The stirring rod of a traditional agitator is set horizontally or vertically, and the turbulence generated during stirring is small, resulting in low stirring efficiency. For this reason, many agitators with inclined stirring rods have appeared on the market. However, the inclination angle of the stirring rods of these agitators is mostly fixed and cannot be adjusted. The stirring efficiency needs to be further improved. Utility Model Content

[0003] In view of the above problems, the utility model provides an agitator with an adjustable inclination angle of a stirring rod. During the stirring process, the inclination angle of the stirring rod can be adjusted as needed. By changing the stirring area, greater turbulence can be generated, further improving the stirring efficiency.

[0004] The technical solution of the utility model is as follows:

[0005] A stirrer with an adjustable inclination angle of a stirring rod, comprising a stirring barrel and a stirring assembly arranged in the stirring barrel, wherein the stirring assembly comprises:

[0006] A stirring shaft is longitudinally arranged in the stirring barrel, and its bottom end passes through the bottom of the stirring barrel;

[0007] A driving motor is arranged at the bottom of the stirring barrel and is drivingly connected to the stirring shaft;

[0008] A sliding sleeve is arranged on the stirring shaft, and a connecting shaft is arranged on the side of the sliding sleeve;

[0009] A first stirring rod, one end of which is provided with a strip-shaped hole matching the connecting shaft;

[0010] A second stirring rod, two ends of which are respectively hinged to the first stirring rod and the stirring shaft;

[0011] A hollow cylinder is arranged at the top of the mixing barrel, and its piston end extends into the mixing barrel and is sleeved on the top of the mixing shaft and fits with the sliding sleeve;

[0012] The two ends of the return spring are respectively connected to the first stirring rod and the second stirring rod.

[0013] The working principle of the above technical solution is as follows:

[0014] The utility model provides a transmission force for the stirring shaft through a driving motor, thereby driving the first stirring rod and the second stirring rod to rotate and stir. In addition, the first stirring rod and the second stirring rod are both inclined stirring rods and are hingedly connected to each other. When the hollow cylinder is started to push the sliding sleeve to slide along the stirring shaft, the inclination angle of the first stirring rod and the second stirring rod will be changed, thereby changing the stirring area, generating greater turbulence, and further improving the stirring efficiency. The reset spring is provided to facilitate the reset of the first stirring rod and the second stirring rod when the hollow cylinder retracts.

[0015] In a further technical solution, a third horizontal stirring rod is provided on the stirring shaft below the second stirring rod. Various combinations of stirring rod structures can better improve the stirring efficiency.

[0016] In a further technical solution, the stirring shaft is rotatably connected to the bottom of the stirring barrel via a bearing, thereby ensuring the stability of the stirring shaft in the stirring barrel.

[0017] In a further technical solution, the piston end of the hollow cylinder is sealingly and slidingly connected to the top of the mixing barrel via a sealing ring.

[0018] In a further technical solution, an O-ring is provided between the piston end of the hollow cylinder and the stirring shaft.

[0019] In a further technical solution, a wear-resistant coating is respectively provided on the bottom surface of the piston end of the hollow cylinder and the top surface of the sleeve. There is dynamic friction between the piston end of the hollow cylinder and the sleeve. Providing a wear-resistant coating can extend the service life of the component.

[0020] In a further technical solution, both ends of the return spring are detachably connected to the middle parts of the first stirring rod and the second stirring rod, respectively, to facilitate maintenance and replacement.

[0021] The beneficial effects of the utility model are:

[0022] The utility model utilizes a hollow cylinder to push the sliding sleeve to slide along the stirring shaft, so as to adjust the inclination angles of the first stirring rod and the second stirring rod according to needs, thereby changing the stirring area, generating greater turbulence, and further improving the stirring efficiency.
