Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a corrosion-resistant and wear-resistant stirrer. Background Art

[0002] A stirrer is a common reaction device in the chemical industry, and its main function is to mix the materials in the kettle evenly. There are hundreds of types of stirrer reactors used in industry.

[0003] For traditional stirrers, the stirring rods are arranged horizontally or vertically. During stirring, the generated turbulence is small, resulting in low stirring efficiency. And when stirring materials, the internal materials will continuously squeeze and rub the inner surface bottom end of the stirring barrel and the stirring device, thus causing the stirring barrel and the stirring device to be more easily worn during long-term use. For stirring some corrosive materials, the inner wall of the stirring barrel and the stirring device are also extremely easy to be corroded during long-term use, thus affecting their service life. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a corrosion-resistant and wear-resistant stirrer. The stirring device can move up and down, which can make the materials in the stirring area mix more fully, and cooperate with the stirring blades and augers to form a better stirring effect, reduce the pressure of the materials on the bottom of the tank body, make the internal wear resistance of the device stronger, and is convenient for cleaning, thereby improving the anti-corrosion effect.

[0005] The technical solution of the utility model is as follows:

[0006] A corrosion-resistant and wear-resistant stirrer includes a tank body and a stirring device arranged in the tank body. The stirring device includes a driving motor I arranged at the top of the tank body. The output end of the driving motor I is in transmission connection with a rotating shaft. A stirring shaft is slidably clamped on the rotating shaft. A sliding rod is arranged inside the stirring shaft along the vertical direction. A sliding rail matching the sliding rod is arranged on the rotating shaft. Multiple groups of augers and stirring blades are arranged on the stirring shaft. A connecting ring is arranged at the top end of the stirring shaft. The connecting ring is sleeved on the rotating shaft. A spring is installed on the connecting ring. The spring is sleeved on the rotating shaft. The other end of the spring is connected to the top of the tank body. A lifting device is arranged at the bottom of the stirring shaft;

[0007] The lifting device includes a connecting rod clamped inside the bottom of the stirring shaft. The connecting rod penetrates through to a placement chamber at the bottom of the tank body. A runner is arranged at the bottom end of the connecting rod. A driving motor II is arranged on the inner bottom wall of the placement chamber. The output shaft of the driving motor II is in transmission connection with a cam for driving the runner to move up and down;

[0008] Anti-corrosion layers and wear-resistant layers are coated on the surfaces of the inner wall of the tank body, the connecting rod, the rotating shaft, the spring, the stirring shaft, the augers and the stirring blades.

[0009] The working principle of the above technical solution is as follows:

[0010] When a corrosion-resistant and wear-resistant stirrer of the present utility model is specifically used, a driving motor 1 drives a rotating shaft to rotate, thereby driving a stirring shaft to rotate, and further driving a stirring blade and an auger to stir materials. The auger and the stirring blade are used in combination to form a better stirring effect, reducing the pressure of the internal materials on the bottom of the tank body. While the stirring shaft is rotating, a driving motor 2 in the placement chamber drives a cam to rotate, thereby driving a runner to move up and down, and further pushing the stirring shaft to move up and down. A spring buffers the up and down movement of the stirring shaft, reducing the impact force on the stirring shaft, the stirring blade, and the auger, thereby increasing the service life. After stirring is completed, and all components of the stirrer are coated with an anti-corrosion layer and a wear-resistant layer, improving the corrosion resistance and wear resistance of the device. When cleaning the device, the up and down movement of the stirring shaft can make it easier to clean every corner inside the tank body, reducing the cleaning difficulty and time, thereby improving the anti-corrosion effect.

[0011] By moving the stirring shaft up and down, the present utility model can make the materials in the stirring area more fully mixed, reducing dead corners and unmixed areas, and can drive the materials to generate a more complex flow pattern in the stirring container, and cooperate with the stirring blade and the auger to form a better stirring effect.

[0012] In a further technical solution, the anti-corrosion layer is made of polytetrafluoroethylene coating, and the wear-resistant layer is made of polyetheretherketone-based wear-resistant coating. The polytetrafluoroethylene coating has high corrosion resistance, and the polyetheretherketone-based wear-resistant coating has excellent high temperature resistance, impact resistance, chemical stability, and wear resistance.

[0013] In a further technical solution, the connecting rod is slidably and sealingly connected to the top of the placement chamber. A slider is provided on the outer side of the connecting rod, and a chute matching the slider is provided on the top plate of the placement chamber to prevent the runner from being driven to rotate, thereby affecting the cooperation stability between the cam and the runner.

[0014] In a further technical solution, a groove matching the side of the runner is provided on the cam to further improve the cooperation stability between the cam and the runner.

[0015] In a further technical solution, sealing rings are provided at the joints of the connecting ring with the rotating shaft and the stirring shaft, and between the stirring shaft and the connecting rod to prevent materials from entering the inside of the stirring shaft, reducing the cleaning difficulty, and thereby preventing the inside of the stirring shaft from being corroded due to long-term non-cleaning.

[0016] The beneficial effects of the present utility model are:

[0017] 1. By moving the stirring shaft up and down, the materials in the stirring area can be more fully mixed, reducing dead corners and unmixed areas. It can drive the materials to generate more complex flow patterns in the stirring container, and cooperate with the stirring blades and augers to form a better stirring effect. Moreover, it is convenient to clean and improves the anti-corrosion effect.

[0018] 2. Anti-corrosion layers and wear-resistant layers are coated on all parts of the stirrer to improve the corrosion resistance and wear resistance of the device.

[0019] 3. Sliders are provided on the outer side of the connecting rod, chutes matching the sliders are provided on the top plate of the placement chamber, and grooves matching the side edges of the rotating wheel are provided on the cam, preventing the rotating wheel from being driven to rotate and ensuring the cooperation stability between the cam and the rotating wheel.

[0020] 4. Sealing rings are provided at the connections between the connecting ring and the rotating shaft, the connecting ring and the stirring shaft, and the stirring shaft and the connecting rod, preventing materials from entering the inside of the stirring shaft, reducing the cleaning difficulty, and thus avoiding the corrosion of the inside of the stirring shaft due to long-term non-cleaning.
