Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle with a circulation pump and a constant temperature heating system. Background Art

[0002] The reactor with a constant temperature heating system can deliver heating medium through an external heater to keep the temperature inside the reactor constant. The heat transfer medium of the heater can be water, oil or other heat transfer fluids, and the heat energy is transferred to the material in the reactor through a delivery pump;

[0003] The existing reactor cannot automatically adjust the gas pressure inside the reactor during the reaction stage, which will lead to incomplete reaction, excessive reaction, etc., resulting in a large amount of impurities. Therefore, the Chinese utility model patent disclosed by the existing publication number CN209138600U: a constant temperature reactor, by adding a pressure regulating valve to the equipment, can adjust the gas pressure generated by the reaction process to meet the reaction conditions, avoid impurities and incomplete reactions, and achieve the purpose of self-regulating the gas pressure, avoiding impurities and incomplete reactions and damage to the equipment. However, this operation makes it possible for the incompletely reacted gas or light components to be discharged only through the vent pipe, which brings great production cost losses to the production, that is, the incompletely reacted gas in the reactor cannot be reused, and direct removal will cause surrounding air pollution on the one hand, and on the other hand it will increase production costs and cause a certain amount of waste of available resources.

The buffer 6 comprises an upper tank body 7 and a lower tank body 8. A pressure discharge pipe 9 is fixedly installed on the outside of the upper tank body 7, and a pressure relief valve 10 is fixedly installed on the upper end of the pressure discharge pipe 9. A connecting pipe A11 is fixedly installed on one end of the pressure relief valve 10, and a connecting pipe B12 is fixedly installed on the outside of the connecting pipe A11. A buffer seat 13 is arranged at the upper position in the upper tank body 7, and the buffer seat 13 is fixedly installed in the upper tank body 7 through a mounting shaft 14.

[0021] like Figure 2-Figure 3 As shown, an upper end pipe 16 is fixedly installed at the center of the upper end of the upper tank body 7, a mounting groove 21 is opened at the lower end of the upper tank body 7, and a mounting groove 21 is also opened at the upper end of the lower tank body 8. The upper tank body 7 and the lower tank body 8 are fixedly connected by a flange, and a lower end pipe A15 is fixedly installed at the center of the lower end of the lower tank body 8, and a lower end pipe B17 is fixedly installed at the lower end of the lower end pipe A15. An exhaust pipe A18 is fixedly installed on the outer side of the lower end pipe B17. The upper end pipe 16 is installed at the upper end of the upper tank body 7 and the lower end pipe A15 is installed at the lower end of the lower tank body 8. The entire buffer 6 is now connected to the reactor 1 and the circulating pump 5 through a pipeline. An exhaust pipe B19 is fixedly installed at one end of the connecting pipe B12.
