Description

Technical Field

[0001] The utility model belongs to the field of reaction kettles, and in particular relates to a novel EPS particle preparation reaction kettle. Background Art

[0002] A reactor is a container that provides a reaction place for various substances to undergo chemical reactions. It includes a reactor body, a stirrer, a transmission device, etc. The stirrer is connected to the transmission device through a coupling and extends into the reactor body. The reactants enter the reactor body through the feed port. When in use, the stirrer is driven by the transmission device to rotate, thereby stirring the reactants in the reactor body to achieve a full reaction.

[0003] As the temperature of the inner cavity of the existing reactor increases, the pressure in the inner cavity of the reactor will also increase. If the pressure is not reduced in time, there will be a risk of explosion; if the stirring in the reactor is not uniform, the reaction will not be complete, affecting the efficiency; in addition, during the stirring process in the reactor, materials will adhere to the inner wall and cannot fall off, affecting the full reaction of the materials.

[0004] Based on this, the utility model designs a heating device for a foam molding machine to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In order to better understand the purpose, structure and function of the utility model, a new type of EPS particle preparation reactor of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, a novel EPS particle preparation reactor comprises a reactor body 1 and a stirring device, wherein the stirring device comprises a driving device, a stirring shaft 8 and a stirring blade 11, wherein the driving device is located above the reactor body 1, and the stirring shaft 8 is fixedly connected to the bottom of the driving device, wherein the stirring shaft 8 is hollow, and two groups of stirring blades 11 are arranged on the stirring shaft 8, wherein each group of stirring blades 11 are arranged relatively on the same horizontal line, and the two groups of stirring blades 11 are arranged vertically, wherein the stirring blade 11 is L-shaped, and the outer edge shape of the stirring blade 11 is consistent with the inner wall of the tank of the reactor body 1, and the reaction products attached to the tank wall of the reactor body 1 or the solids accumulated on the bottom of the tank of the reactor body 1 can be removed by rotation, and the stirring blade 11 can realize stirring in the vertical and horizontal directions, so that the reaction is more sufficient and the reaction efficiency is improved.

[0018] In the technical scheme of the utility model, a self-priming impeller 9 and a gas suction port 7 are also provided in the stirring shaft 8, so that the material in the kettle body can be stirred more fully. The bottom of the kettle body 1 is conical in design, and a discharge port 14 is provided at the bottom. A feed port 6 is provided at the upper right corner of the kettle body 1 for material feeding; a pressure sensor 16 and a pressure relief valve 15 are provided at the upper left end of the inner cavity of the kettle body 1, and the pressure sensor 16 and the pressure relief valve 15 are electrically connected together. The pressure sensor 16 controls the opening or closing of the pressure relief valve 15 by monitoring the inner cavity pressure of the kettle body 1; a jacketed heat exchanger 13 is provided on the outer wall of the kettle body 1, and a steam inlet 12 is provided at the upper left end of the jacketed heat exchanger 13 and a condensation outlet 10 is provided at the lower right end. Heat is transferred or heat is taken away from the reaction materials through circulating flow to realize the heat exchange function.

[0019] In the technical solution of the utility model, the power device includes a driving motor 2, a reducer 3 connected to the lower end of the driving motor 2, a frame 17 connected to the lower end of the reducer 3, a coupling 4 connected to the upper end of the frame 17 and a shaft seal 5 connected to the lower end of the frame 17.

[0020] Working principle: When the reactor is working, first open the feed port 6 to put the material into the cavity of the reactor body 1, then close the feed port 6, and the jacket heat exchanger 13 arranged on the surface of the reactor body 1 heats the reactor body 1 to the temperature required by the material.
