Description

Reactor for paint production

technical field

The utility model relates to a chemical stirring reaction device, in particular to a reaction device for coating production. the

Background technique

In coating production, because the viscosity of the reaction material is generally high, when using general stirring reactor equipment, there may be poor stirring, which will not only damage the reactor, but may also cause damage to the stirring motor and short circuit and other security risks. With the existing reactor stirring device, the liquid level fluctuates during the stirring process, and a large amount of materials will be stained on the wall of the reactor. If it is not removed in time, it will cause waste of materials, and if it is accompanied by heating at the same time, the materials that leave the liquid surface will be heated by the pipe wall Afterwards, a change in properties may occur, and then contact with the materials in the kettle may cause the destruction of all materials in the kettle. Therefore, in the prior art, there is a scraper in the reaction kettle, but due to the gap between the scraper and the wall of the kettle If the clearance is not proper, the scraping will be ineffective or the wall of the kettle will be rubbed. In addition, stirring capacity is one of the key technical indicators of coating production equipment. Good stirring not only provides a good mass transfer condition, but also promotes the dispersion of materials, makes them evenly mixed, and creates a good flow condition in the container space. Eliminate dead corners in the flow field and reduce sticking to the wall. Especially for high-build coatings, poor stirring cannot fully disperse and mix the materials, and the distribution of various raw materials is uneven and the quality is poor. the

Existing paint mixing devices generally have a rotating shaft on which blades are set, and the rotating shaft is rotated by a motor or a handle to drive the blades to rotate to complete the stirring of the paint. During the stirring process, the vortex is single, the stirring takes a long time and the stirring is not uniform enough. the

Utility model content

The purpose of the utility model is to provide a coating reaction device with good stirring effect and no sticking to the wall. the

The technical solution for realizing the purpose of this utility model is: a reaction device for coating production, which has a reactor body, a stirring shaft, and a scraper is fixedly arranged on the stirring shaft, and the position where the scraper is close to the reactor body is a scraper. The scraper forms an included angle of 15°~25° with the wall of the reactor body. the

In the above-mentioned reaction device for coating production, a stirring rod seat is fixedly arranged on the stirring shaft, a stirring rod is fixedly arranged on the stirring rod seat, the end of the stirring rod is a straight blade, and the number of stirring rods is at least 3. The length of the rod is set on the stirring rod seat. the

In the above-mentioned reaction device for coating production, the number of the stirring rods is four. the

In the above reaction device for coating production, the stirring rod is made of stainless steel. the

In the above-mentioned reaction device for coating production, the scraper is made of hard elastic material. the

The utility model has positive effects: (1) the scraper and the angled scraper edge are arranged, which effectively solves the problem of the material sticking to the wall of the reaction kettle in the coating production; It is more uniform and shortens the mixing time; (3) The mixing rods with different lengths are arranged crosswise, forming multiple eddies during the mixing process, and the mixing effect is better. the
