[0002] A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization pots, etc.

[0003] With the development of medical, chemical, biological and other technical fields, a large number of new composite materials have been developed and used. In the process of research and development and production, it is inevitable to carry out mixed reactions of various materials in the reactor. At the same time, corresponding materials need to be added according to the reaction requirements during the reaction. At present, the existing reactors on the market usually use a feeding pipe to directly add materials to the reactor. Although this feeding structure is simple, the materials are gathered together after being added to the reactor, and it is difficult to disperse them in a short time to participate in the reaction. The result is easily affected by insufficient reaction. In view of this, the present application proposes an automatic feeding device. Utility Model Content

The plurality of distribution channels 11 are all connected with the feeding pipe 3, wherein the ring seat 5 at the bottom end of the sleeve 2 and the spray arm 7 are both located inside the reaction tank 1, and the top end of the feeding pipe 3 extends out of the sleeve 2. A fixing rod 9 is fixed on the outer wall of the feeding pipe 3, and the other end of the fixing rod 9 is fixed to the top end of the reaction tank 1, thereby the feeding pipe 3 is fixed on the reaction tank 1, and the sleeve 2 can rotate relative to the feeding pipe 3.

[0025] Through the above-mentioned structural mode, the feeding pipe 3 is connected to the material adding equipment, and electronic control equipment such as solenoid valves are installed at the connection to control the automatic addition of materials. Secondly, the driving mechanism 4 is used to drive the sleeve 2 to rotate relative to the feeding pipe 3, and the material is transported to the distribution head 10 via the feeding pipe 3. The sleeve 2 drives the rotating sleeve 6 and the spray arm 7 to rotate. During the rotation of the spray arm 7, the multiple distribution channels 11 on the distribution head 10 are aligned and connected in turn. During this dynamic rotation process, the material can rotate with the spray arm 7 and be dispersed and sprayed into the reaction tank 1, thereby realizing automatic and uniform addition of materials, and effectively solving the problem that materials are easily agglomerated and affect the mixing effect when they are piled up and delivered.

[0026] In this embodiment, at least two spray arms 7 are symmetrically arranged, and multiple feeding nozzles 8 are arranged at the bottom of the two spray arms 7 to further disperse the added materials. A ring seat 5 is rotatably mounted on the sleeve 2, and the ring seat 5 is fixed on the top of the reaction tank 1 for positioning and rotating the sleeve 2.
