Description

Technical Field

[0001] The utility model relates to the technical field of reaction tanks, in particular to an explosion-proof reaction tank. Background Art

[0002] A reaction tank is a container for chemical or physical reactions, which is divided into pressurized and normal pressure. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the petroleum, chemical, rubber and food industries to complete pressure vessels for vulcanization, hydrocarbonization, polymerization and other process, such as reactors, reaction pots, decomposition pots and polymerization pots.

[0003] At present, the reaction tank may explode when in use, which is generally caused by excessive internal gas pressure. Therefore, in the prior art, multiple pressure gauges and pressure relief pipes are generally installed above the reaction tank to deal with the explosion problem. However, in some reaction processes, a large amount of gas will be generated in an instant, causing high pressure. If only pressure relief pipes and pressure gauges are used to release the pressure, the speed is obviously not fast enough, making the explosion problem difficult to avoid. Therefore, it is urgent to design an explosion-proof reaction tank to solve the above problem. Utility Model Content

[0008] Furthermore, a vacuum pipe is fixed at the bottom of the gap between the outer wall of the high-pressure resistant inner container and the inner wall of the high-pressure resistant outer shell, and a first valve is installed on the vacuum pipe.

[0009] Furthermore, the circumferential outer wall of the high-pressure resistant shell near the top is fixed with equidistantly distributed ear seats, and the bottom of the ear seats is fixedly installed with support columns, the same connecting frame is fixedly installed at the bottom of one side of the support column, and the bottom of the support column is fixedly installed with universal wheels, one side of the support column is provided with equidistantly distributed slots, and the inner wall of the slot is fitted with a reinforcement ring, which is sleeved on the outer wall of the high-pressure resistant shell.

[0010] Furthermore, a pressure relief pipe is fixed to the top of one side of the high-pressure resistant shell, and a pressure gauge is fixedly installed at one end of the pressure relief pipe. An air relief pipe is fixed to one side of the top of the pressure relief pipe, and a second valve is installed on the air relief pipe.

[0011] Furthermore, a discharge pipe extending from the high-pressure resistant shell is fixed at the middle position of the bottom of the high-pressure resistant inner tank, and a third valve is installed on the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, by using the cooperation of the high-pressure resistant shell, the high-pressure resistant liner, the reinforcement plate, the ear seat, the support column and the reinforcement ring, the gap between the high-pressure resistant shell and the high-pressure resistant liner can be reinforced under the action of the reinforcement plate, and the outside of the high-pressure resistant shell can be reinforced by the reinforcement ring, so as to achieve a good reinforcement and support effect on the whole reaction tank, improve the impact resistance of the whole reaction tank, and form the explosion-proof effect of the tank body itself;

[0015] In the utility model, the vacuum pump is connected to the vacuum pipe to draw out the vacuum at the gap between the high-pressure resistant outer shell and the high-pressure resistant inner shell by utilizing the cooperation of the arranged vacuum suction pipe, the movable chamber, the spring, the guide rod, the movable plate and the piston sleeve. When a strong pressure is instantly generated in the reaction tank, the movable plate and the piston sleeve can be squeezed to move in the movable chamber. At this time, a large amount of gas enters the gap between the high-pressure resistant outer shell and the high-pressure resistant inner shell along the connecting port, so that the gas is absorbed through the gap between the high-pressure resistant outer shell and the high-pressure resistant inner shell, thereby achieving the effect of quickly releasing the air pressure, preventing the pressure in the reaction tank from being too high, and avoiding the explosion problem.
