Description

Technical Field

[0001] The utility model relates to the field of epoxy resin reaction equipment, in particular to an epoxy resin reaction kettle. Background Art

[0002] Epoxy resin is a kind of high molecular polymer. Epoxy resin refers to a general term for a class of polymers containing two or more epoxy groups in the molecule. It is the condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. Epoxy resin is an amorphous viscous liquid with no fixed melting point, insoluble in water, and will not harden itself. Therefore, it is basically impossible to use alone. The reaction of epoxy resin usually requires a certain temperature to activate or accelerate.

[0003] For example, the patent with authorization announcement number CN221334156U discloses a liquid epoxy resin synthesis reactor, in which a water bath tube is arranged in the heating chamber of the side wall of the reactor body, and the water bath tube is arranged in sequence along the circumference of the reactor body. The water inlet end and the water outlet end of the water bath tube are respectively connected to the water bath heater through a circulating water pipe. The stirring mechanism includes a driving component and a first stirring component and a second stirring component connected to the driving component. The first stirring component and the second stirring component are both arranged inside the reactor body, the first stirring component is located at the center of the reactor body, and the second stirring component is arranged around the first stirring component. The first stirring component and the second stirring component can be driven by the driving component to rotate in the opposite direction.

[0004] In the liquid epoxy resin synthesis reactor of the above patent, the counter-rotation of the first stirring component and the second stirring component can fully stir and mix the raw materials in the reactor body, so that the drugs are fully in contact with each other; however, the disadvantage of the above patent is that: the above patent adopts the method of introducing all the materials for the reaction from the top of the reactor, and at this time, the stirring component is required to fully mix all the materials, and different materials have different specific gravities, so it takes a long time for the materials to be thoroughly mixed.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0011] The auxiliary material introduction structure is provided with two groups, and the two groups of auxiliary material introduction structures are symmetrically arranged up and down.

[0012] Furthermore, the horizontal stirring group includes a mounting disc and three first stirring blades arranged in a circular array on the mounting disc.

[0013] Furthermore, the bottom stirring group includes a mounting tube and three second stirring blades arranged in a circular array on the side wall of the mounting tube, wherein the bottom of the second stirring blades is inclined.

[0014] Furthermore, the driving device includes a driving motor, which is fixedly mounted on the top of the reactor body through a motor bracket, and the top of the stirring shaft passes through the reactor body and is drivingly connected to the output shaft of the driving motor through a coupling.
