Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a high-efficiency low-speed stirrer. Background Technology

[0002] A stirrer is a device that forces convection and uniformly mixes liquid and gaseous media. The type, size, and rotational speed of the stirrer affect the distribution of stirring power between the overall flow and turbulent pulsations. Generally speaking, the power distribution of turbine stirrers is favorable to turbulent pulsations, while propeller stirrers are favorable to the overall flow. For the same type of stirrer, under the same power consumption conditions, a large-diameter, low-speed stirrer consumes power mainly in the overall flow, which is beneficial to macroscopic mixing, while a small-diameter, high-speed stirrer consumes power mainly in turbulent pulsations, which is beneficial to microscopic mixing.

[0003] Existing agitators are generally hand-held by operators. Prolonged use can easily lead to operator fatigue, affecting their ability to use the agitator and increasing their workload. In addition, existing agitators have low efficiency and cannot effectively mix liquids, thus reducing their practicality. Utility Model Content

[0006] The above technical solution allows operators to easily adjust the height of the device without having to hold it by hand, and provides stable support for the device's efficient stirring mechanism.

[0007] Furthermore, the high-efficiency stirring mechanism includes a geared motor, the bottom surface of which is fixedly connected to the top surface of the support shell plate. A first stirring rod is fixedly connected to the output end of the geared motor. A drive gear is fixedly connected to the upper side of the first stirring rod wall located on the inner wall of the support shell plate. Driven gears are meshed around the surface of the drive gear. Second stirring rods are fixedly connected to the inner walls of the four driven gears. A first stirring blade is fixedly connected to the lower side of the first stirring rod wall. Second stirring blades are fixedly connected to the lower sides of the four second stirring rod walls.

[0008] Through the above technical solution, this device does not require manual operation, reducing the workload of operators and making it more convenient for them to use the device. At the same time, it can improve the working efficiency of the device, enabling it to efficiently stir liquids and improve its practicality.

[0009] Furthermore, the upper end of the threaded rod is rotatably connected to the upper side of the inner wall of the adjusting cavity, the opposite sides of the two connecting blocks are fixedly connected to the left and right sides of the adjusting block, and the opposite sides of the two connecting blocks are fixedly connected to the left and right sides of the inner wall of the connecting hole plate, the lower end of the first stirring rod penetrates the top surface of the supporting shell plate and the lower side of its inner wall to one side of the bottom surface of the supporting shell plate, the upper and lower sides of the four driven gears are rotatably connected to the upper and lower sides of the inner wall of the supporting shell plate, the upper ends of the four second stirring rods are rotatably connected to the upper side of the inner wall of the supporting shell plate, and the lower ends of the four second stirring rods penetrate the lower side of the inner wall of the supporting shell plate to one side of its bottom surface.

[0010] The above technical solutions can increase the stability between some internal components of the device, ensure the normal use of the device, and make the device more stable during operation.

[0011] Furthermore, foot brake casters are fixedly connected to the four corners of the bottom surface of the base plate.

[0012] The above technical solution allows operators to easily move the device, making it more convenient to use and move it due to its flexibility.

[0013] Furthermore, a movable handle is fixedly connected to the upper right side of the support column, and the surface of the movable handle is frosted.

[0014] The above technical solution can increase the friction between the operator's hand and the moving handle, making it easier for the operator to grip the moving handle and thus providing a good gripping point for the operator when moving the device, making the device easier to move.

[0015] Furthermore, both the first stirring blade and the four second stirring blades are made of stainless steel.

[0016] Through the above technical solutions, the first stirring blade and the second stirring blade have advantages such as easy cleaning, good corrosion resistance, high strength, and low temperature resistance, making the first stirring blade and the second stirring blade more practical.

[0017] Furthermore, a protective cover is fixedly connected to the top surface of the supporting shell plate, and four cooling holes are provided on both the left and right sides of the protective cover.

[0018] The above technical solution can protect the geared motor and increase the breathability of the protective cover, preventing the geared motor from overheating and being damaged after long-term use, thereby improving the service life of the geared motor.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] This invention uses a servo motor to drive a threaded rod to rotate. The rotating threaded rod drives an adjusting block to move up and down. The moving adjusting block, through a connecting block, drives a connecting plate to move up and down, thereby adjusting the height of the high-efficiency stirring mechanism. This eliminates the need for manual operation. A reduction motor drives a first stirring rod to rotate. The first stirring rod, through a driving gear, drives a driven gear and a second stirring rod to rotate. The rotating first and second stirring rods respectively drive the first and second stirring blades to stir in opposite directions. This structure eliminates the need for manual operation, reducing the operator's workload and making the device more convenient to use. It also improves the device's efficiency, enabling efficient stirring of liquids and enhancing its practicality.

[0021] This invention, through the design of foot brake omnidirectional wheels, facilitates the movement of the device by the operator. The device's flexibility makes it more convenient to move during use. The addition of a handle increases the friction between the operator's hand and the handle, making it easier for the operator to grip and apply force, thus providing a better point of leverage for movement.

[0022] This invention protects the geared motor by incorporating a protective cover and cooling holes, while also increasing the breathability of the protective cover to prevent the geared motor from overheating and being damaged after prolonged use, thereby extending the service life of the geared motor.

The rotating driving gear 13 drives the driven gear 14, which is meshed with it, to rotate in the reverse direction. The rotating driven gear 14 drives the second stirring rod 15 to rotate in the reverse direction. The forward-rotating first stirring rod 12 and the reverse-rotating second stirring rod 15 respectively drive the corresponding first stirring blade 16 and second stirring blade 17 to rotate, thereby simultaneously stirring the external liquid that needs to be stirred in both directions, which improves the stirring efficiency of this device.
