In the prior art, fan paddles or spear paddles are generally used for polymerization reactions. After several batches of production, a large amount of residue will appear on the inner wall of the kettle, which affects the production heating system and has a great impact on product quality.

Utility model content

The technical problem to be solved by the utility model is to provide an adhesive reaction kettle for automatically cleaning the residue on the inner wall of the kettle body.

The technical scheme that the utility model solves its technical problem adopts is:

An adhesive reaction kettle, including a kettle body, the center of the kettle body is provided with a stirring shaft, the upper end of the stirring shaft is connected with a motor installed on the outside of the kettle body, the lower end of the stirring shaft is equipped with paddles, and at least two Scraper, the scraper is spiral along the axis of the kettle body or parallel to the kettle body. There are several horizontal through holes along the length of the scraper on the scraper, and the through holes between different scrapers are staggered vertically. , the outside of the scraper squeezes the inner wall of the kettle body, and scrapes and cleans the inner wall of the kettle body when the stirring shaft rotates.

Further, there are two scrapers and they are arranged oppositely.

Further, the scraper is mounted on the stirring shaft through a bracket fixed at the lower end of the stirring shaft.

Further, the scraper is fixedly installed on the outer side of the paddle.

Further, the upper end of the scraper is higher than the upper end of the paddle, and the lower end of the scraper is flush with the lower edge of the inner wall of the kettle body.

Further, the scraper is made of elastic silicone.

The beneficial effects of the utility model are: adding a silicone scraper along the inner wall of the kettle, so that the materials sticking to the inner wall of the kettle are scraped off in time to participate in the reaction during the reaction, improving the accurate ratio of the reaction, and reducing the residue on the inner wall , to facilitate the cleaning of the reaction kettle, and the silicone scraper is flexible, high temperature resistant, and will not have adverse effects on the reaction.

Detailed ways

In order to make those skilled in the art better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, an adhesive reaction kettle includes a kettle body 1, a stirring shaft 2 is arranged at the center of the kettle body 1, a motor 4 is installed on the outside of the kettle body 1, and the output end of the motor 4 is connected to the deceleration The device 5 is connected, the upper end of the stirring shaft 2 is connected with the deceleration device 5, the lower end of the stirring shaft 2 is fixedly connected with the paddle 3 through the connecting plate, and the paddle 3 rotates under the drive of the motor 4, thereby the acrylic acid in the kettle body 1 The ester adhesive is stirred. In order to reduce the residue of the acrylate adhesive on the inner wall of the kettle body 1, a scraper is fixed on the outside of the paddle 3, and the outer side of the scraper is close to the inner wall of the kettle body 1. When the motor 4 drives the stirring shaft 2. When rotating, the scraper scrapes and cleans the inner wall of the kettle body 1 under the drive of the paddle 3. In order to facilitate the cleaning of the reactor, the scraper is made of elastic silicone material. Of course, the scraper can also be installed on a bracket fixedly connected to the lower end of the stirring shaft 2 .

As shown in Figure 1, when the paddle 3 stirs the acrylate adhesive, the acrylate adhesive rushes to the inner wall of the kettle body 1 under the action of centrifugal force, so that the liquid level at the inner wall of the kettle body 1 rises. In order to solve this problem , the upper end of the scraper is higher than the upper end of the paddle 3, and simultaneously in order to clean the entire inner side wall of the kettle body 1, the lower end of the scraper is flush with the lower edge of the inner side wall of the kettle body 1.

As shown in Figure 1, the scraper is in the shape of a strip; the scraper can also be spiral along the axis of the kettle body 1, not shown in the figure. When the scraper is strip-shaped, it is vertically arranged.

There are two scrapers and they are arranged opposite to each other along the axis of the stirring shaft 2. The scrapers are provided with horizontal through holes 7 uniformly distributed along the length direction of the scrapers. The through holes 7 on the two scrapers are staggered from each other, that is, at the same height , there is a through hole 7 on only one scraper. When the scraper squeezes and cleans the inner wall of the kettle body 1, the pressure on the inner wall of the kettle body 1 on the part with the through hole 7 on the scraper is smaller than that of the part without the through hole 7, and the two scrapers perform complementary operations. The same height of the inner wall of the body 1 is subjected to different extrusion forces of the two scrapers, so that the inner wall of the kettle body 1 is cleaned more cleanly, and the residue at the front end of the scraper can be discharged backward along the through hole 7 with the rotation of the scraper , to facilitate the scraping operation of the scraper.

The above implementation methods do not constitute a limitation of the protection scope of the technical solution. Any modifications, equivalent replacements and improvements made within the spirit and principles of the above implementation methods shall be included in the protection scope of the technical solution. .
