Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of modified dibasic lead phosphite, in particular to a lead melting furnace with a tumbling mechanism. Background Art
[0002] Dibasic lead phosphite has the ability to resist oxidation and shield ultraviolet rays, and has strong weather resistance, and is particularly suitable for PVC outdoor non-transparent products. Dibasic lead phosphite is referred to as di-salt, and tri-salt and di-salt have a synergistic effect. It is also used as a filler stabilizer for polymer materials, and is generally used more in the production of white products.
[0003] Dibasic lead phosphite is modified by yellow lead ochre with sulfuric acid and phosphorous acid, and fully catalyzed by glacial acetic acid, and then dried and crushed to obtain dibasic lead phosphite. However, in the production process of modified dibasic lead phosphite, the existing internal devices using lead melting furnaces for reaction are mostly only provided with stirring mechanisms, and in the stirring process, powder products such as yellow lead ochre will have a small amount of floating phenomenon, resulting in insufficient reaction stirring. In addition, in the process of modifying dibasic lead phosphite, the lead melting furnace is not required to be continuously heated. For example, in the first step of the modification, yellow lead ochre and acetic acid need to be mixed and stirred for more than 30 minutes, and then heated to 60°C for reaction. In the overall modification operation, the manual switch of the lead melting furnace is required, which is too cumbersome and the time cannot be accurately controlled, thereby reducing the working efficiency of the lead melting furnace.

[0014] 2. The utility model cooperates with the stirring mechanism and the turning mechanism inside the main body of the lead melting furnace, so that the operator can start the first motor and the second motor at the same time. The output shaft of the first motor drives the sealing plate and the rotating roller to perform a circle of rotation inside the main body of the lead melting furnace. The rotating roller drives the stirring main roller to stir and react media such as yellow lead, sulfuric acid, and phosphorous acid. The output shaft of the second motor drives the rolling arc plate to continuously roll the reaction medium on the upper part to the lower part. The reaction medium rolled to the lower part can effectively achieve the effect of sufficient reaction stirring under the stirring of the stirring main roller, thereby further improving the working efficiency of the modified dibasic lead phosphite.
[0015] In addition, during the stirring and rotating process, the main stirring roller will also drive the scraper plate and the lower scraper rod to rotate at the same time. The scraper plate and the lower scraper rod will respectively scrape the inner wall and the inner bottom wall of the lead melting furnace body, thereby avoiding the phenomenon of the reaction medium adhering to the inner wall of the lead melting furnace body and ensuring the completeness of the modification reaction.
