Description
Technical Field
[0001] The utility model relates to the technical field of polyurethane production equipment, in particular to a cooling device for a polyurethane reaction kettle. Background Art
[0002] As a new type of waterproof sealing material, polyurethane foaming material is commonly used in the waterproof sealing construction of bridge expansion joints. The polyurethane foaming material is mainly composed of material A and material B, and is a polymer formed by mixing through a special foaming machine and foaming on-site by high-pressure spraying. The current processing method of material A is: in the reaction kettle, each raw material is stirred and premixed into a prepolymer. During the synthesis process, the reaction kettle needs to be gradually heated for vacuum dehydration, and after dehydration, it is cooled and then the isocyanate component is added. A large amount of heat is generated during the premixing process due to chemical reactions, so the cooling process is quite slow, making it very difficult to cool quickly. Sometimes, heat dissipation fins are installed outside the reaction kettle to improve its heat dissipation efficiency. Although this method is feasible, it results in poor heat preservation performance of the reaction kettle during the initial use.
[0003] Therefore, it is necessary to provide a cooling device for a polyurethane reaction kettle to solve the above technical problems. Summary of the Utility Model

A support rod is vertically installed on the top surface of the base. The top end of the support rod is provided with a reaction kettle main body. An electric push rod is vertically installed on the top surface of the base. The output end of the electric push rod is provided with a support plate. A circular ring is arranged between the two support plates. The bottom surface of the circular ring is provided with heat dissipation fins.
[0006] Preferably, threaded holes are formed on the surfaces of both the circular ring and the heat dissipation fins, and the heat dissipation fins are fixedly connected to the circular ring through fasteners.
[0007] Preferably, a plurality of heat dissipation fins are provided, and the plurality of heat dissipation fins are equidistantly arranged and circumferentially installed on the bottom surface of the circular ring.

Compared with the prior art, in this cooling device for a polyurethane reactor, by separately arranging the heat sink from the reactor main body, it is convenient to quickly dissipate heat from the reactor main body while not affecting the heating and heat preservation functions during the later use of the reactor main body. When operating, the staff puts polyurethane raw materials into the reactor main body through the feed port for processing. When it is necessary to quickly dissipate heat from the processed materials, the staff starts the electric push rod through the controller. Then, the electric push rod drives the heat sink to move upward through the ring, and then makes the heat sink contact the outer wall of the reactor main body. Thus, under the action of the heat sink, the reactor main body can be quickly cooled. After the heat dissipation is completed, the heat sink is separated from the reactor main body in the above-mentioned manner to facilitate ensuring the heat preservation performance of the subsequent reactor main body.
