Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a heating and cooling device for a medium-density fiberboard glue-making reaction kettle. Background Art

[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 achieved. The reactor is usually heated by passing steam into the reactor jacket, and hot water can also be passed into the reactor to heat the materials in the reactor.

[0003] According to the description of a reactor cooling and heating device disclosed in the patent website (authorization announcement number: CN 215693925U), "The utility model discloses a reactor cooling and heating device, aiming to provide a reactor cooling and heating device with a smaller occupied area. The key points of its technical solution are that it includes a reactor, and a temperature control device is arranged on the outer wall of the reactor. The temperature control device includes a coil wrapped on the outer wall of the reactor, and a jacket inlet main pipe and a jacket outlet main pipe connected to the coil are arranged on both sides of the reactor. A venturi steam heater is also connected to the bottom of the jacket inlet main pipe, and a steam pipe is arranged at the bottom of the venturi steam heater, and a steam control valve is arranged on the steam pipe."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model is provided with evenly distributed stirring blades on the stirring rod to stir the materials inside the reactor. The steam control valve is opened through the second valve controller, and the Venturi steam heater is turned on, and the second control valve is opened, so that the water in the coil is evenly heated, thereby heating the inside of the reactor. When the internal temperature is too high, the first control valve will be opened, so that the cooling water in the cooling water pipe will enter the coil to cool the inside of the reactor. At the same time, due to continuous heat absorption, the cooling water will be discharged from the circulating water pipe. However, in actual use, the unidirectional stirring blade has a slow stirring efficiency. Secondly, the material will adhere to the inner wall of the reactor, which will cause material waste and leave residues inside the reactor, which is not conducive to the next use. Therefore, it is necessary to improve a heating and cooling device for a medium-density fiberboard glue-making reactor to solve the above problems. Utility Model Content
