Description

A scraper driving device

[technical field]

The utility model relates to the technical field of high-speed dispersing machines, in particular to a scraper driving device.

[Background technique]

The high-speed disperser is suitable for stirring, dissolving and dispersing liquid and liquid-solid phase materials in the chemical industry such as paint, dye, pigment, ink, adhesive, etc. It has continuous operation, high dispersion efficiency, large output, convenient operation, safety and reliability. Etc. At present, the high-speed dispersing machines on the market generally do not have a scraper, that is, only the dispersing disc in the middle of the material cylinder performs high-speed rotation. When waiting, the mixing and dispersion are uneven and there are dead angles, and the slurry is easy to stick to the wall of the material cylinder, which is not conducive to cleaning and maintenance.

[utility model content]

The purpose of this utility model is to solve the above-mentioned deficiencies and provide a scraper driving device, which not only accelerates the stirring and dispersing of materials, makes the stirring and dispersing uniform without dead ends, but also makes the cleaning and maintenance of the material cylinder very convenient and simple. It solves the technical problem of uneven dispersion and dead angle when stirring and dispersing slurry with high viscosity and consistency.

In order to achieve the above purpose, a scraper driving device is designed, which includes a belt motor reducer 3, a small sprocket 4, a cylinder cover 5, a chain 7, a large sprocket 8 and a scraper 11, and the belt motor reducer 3 is installed in a dispersed On the cylinder cover 5 of the material cylinder 12 of the machine, the output end of the motor reducer 3 is equipped with a small sprocket 4, the small sprocket 4 is connected with the large sprocket 8 through a chain 7, and the scraper 11 is fixed Connected to the lower part of the large sprocket 8, the other end of the scraper 11 is close to the wall of the material cylinder 12, and the motor reducer 3 drives the scraper 11 through the small sprocket 4, the chain 7, and the large sprocket 8 Make a circular rotation.

Outer tube 2 is installed on the transmission shaft 1 of described disperser, and described outer tube 2 is coaxially arranged with transmission shaft 1, and described outer tube 2 is installed in the cylinder cover 5 center of material cylinder 12, and described outer tube 2 and Bearings 9 are installed between the large sprockets 8 , and the lower part of the bearings 9 is fixedly connected to the bottom of the outer tube 2 through a gland 10 .

A bottom cover 6 is installed below the small sprocket 4 , and the bottom cover 6 is fixedly connected to the cylinder cover 5 of the material cylinder 12 .

Compared with the prior art, the utility model has a novel and simple structure and a reasonable design. The scraper is driven to rotate in a circle through a reducer with a motor, so that the scraper close to the wall of the material barrel drives the material to move toward the middle of the material barrel, thereby accelerating Stirring and dispersion of the material is ensured, so that the stirring and dispersion are uniform and there is no dead angle; at the same time, because the rotating scraper is close to the cylinder wall and rotates in a circle, it can easily scrape off the high viscosity and consistency sticking on the cylinder wall of the material cylinder. The slurry makes the cleaning and maintenance of the material cylinder very convenient and simple, and it is worthy of popularization and application.
