Description

Technical Field

[0001] The utility model relates to the technical field of alkylation kettles, in particular to an adjustable alkylation kettle. Background Art

[0002] An alkylation kettle is one of the most common alkylation reactor devices. It usually consists of a kettle body, a stirrer, a heater, a cooler, a feed inlet, a discharge outlet, etc. Reactants react inside the kettle body and are evenly mixed and the reaction is completed with the help of the stirrer.

[0003] The kettle body of the alkylation kettle is usually made of an alloy material with high temperature resistance and corrosion resistance. Its design should ensure good heat conductivity and sufficient reaction space to meet the reactions of different scales and production requirements.

[0004] An alkylation kettle pressure alarm disclosed in the prior art with the publication number CN220924652U includes a short pipe fixedly arranged on and communicated with the alkylation kettle. One end of the short pipe away from the alkylation kettle is connected and communicated with a pipe body. One end of the pipe body away from the short pipe is hermetically provided with a cover. A piston block is hermetically and slidably arranged inside the pipe body. A pressure sensor is fixedly arranged on the inner wall of the cover. An annular plate is sleeved outside the pressure sensor and the annular plate is fixedly connected with the inner wall of the pipe body.

[0005] This alkylation kettle pressure alarm determines whether the pressure of the alkylation kettle reaches the threshold value through the cooperation of components such as a spring and a pressure sensor. However, its pressure threshold value cannot be adjusted according to actual needs, which reduces its use effect. At the same time, when the threshold value is reached, it does not have an emergency function, and there are risks such as overheating and overpressure of the alkylation kettle, which also reduces the functionality of the pressure alarm.

The top of the small piston 9 is fixedly connected with a piston rod 8, and the piston rod 8 penetrates through the piston cylinder 10 and is fixedly connected with the fixing plate 21. When the internal pressure of the kettle body 1 reaches the set value, it will overcome the elastic force of the spring 18, thereby pushing the small piston 9 and the piston rod 8 to rise.

[0027] A lifting assembly is installed on the top of the piston assembly, and the guide rod 16 penetrates through the movable end of the lifting assembly. The lifting assembly includes a vertical rod 6, and the vertical rod 6 is fixedly connected with the piston cylinder 10. A knob 15 is provided at the top of the vertical rod 6. The bottom of the knob 15 is fixedly connected with a screw rod 19, and the screw rod 19 penetrates through the vertical rod 6 and is rotatably connected with it. A sliding seat 17 is threadedly sleeved on the outer surface of the screw rod 19, and the sliding seat 17 is slidably sleeved on the outer surface of the guide rod 16. The sliding seat 17 is slidably attached to the vertical rod 6, and the spring 18 abuts against the sliding seat 17.

The exhaust pipe 12 can be communicated with an existing filtration device in the prior art to avoid polluting the environment with the discharged gas; during the reaction process of the kettle body 1, if the internal pressure of the kettle body 1 is abnormal and exceeds a certain value, it will push the small piston 9 and the piston rod 8 to rise. The piston rod 8 will push the fixed plate 21 and the pressing plate 22 to rise until the pressing plate 22 contacts the travel switch 20. Then the air pump 5 operates to send the gas inside the kettle body 1 into the cylinder 2.

After a period of time, the exhaust pipe 12 opens, and the gas is discharged through the exhaust pipe 12.
