Description

Technical Field

[0001] The utility model relates to the technical field of rubber accelerators, and more specifically to a distillation kettle for producing rubber accelerators. Background Art

[0002] Rubber accelerator M (used for tires, rubber shoes, and industrial rubber products) generally refers to 2-mercaptobenzothiazole. 2-Mercaptobenzothiazole, also known as accelerator M, is an organic compound with a chemical formula of C7H5NS2. It is a light yellow crystalline powder. It is mainly used as a sensitive reagent for the determination of gold, bismuth, cadmium, cobalt, mercury, nickel, lead, thallium, and zinc, and a rubber accelerator. Rubber accelerator refers to a rubber vulcanization accelerator. Rubber vulcanization is mainly carried out using sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators came into being. The addition of accelerators to the rubber can activate the vulcanizer, thereby accelerating the cross-linking reaction between the vulcanizer and the rubber molecules, achieving the effect of shortening the vulcanization time and reducing the vulcanization temperature. The main vulcanization accelerators used are mainly sulfonamides, thiazoles, thiurams, and some guanidines, thioureas, and dithiocarbamates according to their chemical structures. Among them, sulfonamides have the best comprehensive performance and are the most widely used. Rubber accelerators can be produced using distillation kettles.

[0003] For example, the utility model with announcement number CN215026085U discloses a high-efficiency distillation kettle for rubber vulcanization accelerator NS. First, the material is loaded into the interior of the distillation kettle body. During distillation, the distilled gas is guided to the interior of the condenser through the distillation tube. After the gas is cooled by the condenser, the distilled substance is cooled into a liquid state and then discharged from the water outlet pipe. By starting the motor, the motor drives the rotating shaft to rotate through the coupling, prompting multiple stirring rods and connecting rods to rotate, and the material in the distillation kettle body is stirred. The connecting rod drives the stirring plate to rotate, and the material in the distillation kettle body can be stirred. At this time, by starting the air pump, the air pump can draw external air into the ventilation pipe, and then the ventilation pipe will flow air into the jet pipe. By opening the electric valves in the multiple jet heads, the jet pipe will flow air into the multiple jet heads. The multiple jet heads cooperate with the stirring plates to stir, and then the material precipitated at the bottom of the distillation kettle body is turned over, so that the material in the distillation kettle can be fully distilled, and the recovery efficiency of the material is effectively improved.

[0004] Regarding the above scheme: The inventor believes that the above reference document uses a stirring plate to stir the rubber accelerator material inside the distillation kettle, and then uses an air pump to spray air from the jet head to the bottom of the distillation kettle to turn over the precipitated material at the bottom of the distillation kettle, thereby improving the distillation effect. However, since the material at the bottom of the distillation kettle is turned over by jetting, when there is too much material and it is too heavy, the sprayed air will have difficulty blowing up the material at the bottom to turn it over, resulting in poor use effect. Utility Model Content

[0034] The working principle and use process of the utility model are as follows: when using the device, firstly, the rubber accelerator is poured into the interior of the distillation kettle body 1 through the feed port 23 for distillation, and is located on the upper side of the first push plate 36 and the second push plate 37, and then the first motor 21 is started to drive the stirring rod 22 to stir the rubber accelerator, and at the same time, the second motor 39 can be started to drive the rotating rod 32 and the gear 33 to rotate, and the gear 33 will drive the first rack 34 and the second rack 35 to move in the opposite direction, and at the same time, the first rack 34 and the second rack 35 will respectively drive the first push plate 36 and the second push plate 37 to move in the opposite direction, when the first push plate 36 and the second push plate 37 move in the opposite direction, all the rubber accelerators can be pushed to flip, so that the rubber accelerator at the bottom can flip, and the first push plate 36 The first push plate 36 and the second push plate 37 are driven by the second motor 39. Even if the rubber accelerator is large and heavy, it can be pushed and tumbled smoothly, and the tumbling effect is better than that of the jet. When the second motor 39 drives the gear 33 to rotate back and forth repeatedly, the first push plate 36 and the second push plate 37 will continue to push and tumble the rubber accelerator. Because the rubber accelerator is located on the first push plate 36 and the second push plate 37, the first push plate 36 and the second push plate 37 can push all the rubber accelerators to tumble, and it is not easy for some rubber accelerators to not be pushed and tumbled. At this point, the problem of using jet to tumble the material at the bottom of the distillation kettle body 1 can be solved. When the material is too much and too heavy, the ejected gas will find it difficult to blow up the material at the bottom for tumbling, which leads to poor use effect.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
