Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, and particularly relates to a reaction kettle for petrochemical industry. Background Art

[0002] Reaction kettles are widely used in petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. For example, reactors, reaction pots, decomposition pots, polymerization kettles, etc. The materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. The structural design and parameter configuration of the container are carried out according to different process condition requirements. The design conditions, processes, inspections, manufacturing, and acceptance need to be based on relevant technical standards to achieve the heating, evaporation, cooling, and low- and high-speed mixing reaction functions required by the process.

[0003] During the use of a petrochemical reaction kettle, the stirring mechanism installed on the stirring motor will be attached with liquid. When it is necessary to repair the stirring mechanism installed on the stirring motor, the sealing cover needs to be disassembled first. After disassembly, the sealing cover also needs to be placed obliquely on the ground to repair the stirring mechanism, which is rather troublesome. Summary of the Utility Model

A stirring motor is fixedly installed on the upper surface of the sealing cover. A support frame is fixedly installed on the rear surface of the reaction kettle main body. A lifting motor is fixedly installed on the lower surface of the support frame. A threaded rod is fixedly installed at the output end of the lifting motor. A bracket is sleeved on the surface of the threaded rod.

[0007] Preferably, a connecting plate is fixedly installed on the rear surface of the sealing cover. A turning block is fixedly installed on the rear surface of the connecting plate. Rotating shafts are fixedly installed on both side surfaces of the turning block. Gears are fixedly sleeved on the surface of the rotating shafts and located at both ends.

Reinforcing blocks are fixedly installed on the upper surface of the support plate near both sides. A bushing is fixedly installed on the front surface of the reinforcing block. A limiting slider is fixedly installed on the rear surface of one side of the bushing.

[0010] Preferably, a threaded hole is formed in the upper surface of the support plate near the rear. The upper end of the threaded rod extends into the lifting groove and penetrates the threaded hole. The limiting slider is embedded in the limiting chute.

[0011] Preferably, the rotation shaft passes through the bushing. An oil injection pipe is fixedly installed on the sealing cover. A stirring mechanism is fixedly installed at the output end of the stirring motor.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by setting the sealing cover, the support frame, the lifting motor, the bracket, and the threaded rod to cooperate with each other, when it is necessary to repair the stirring mechanism installed on the stirring motor, the lifting motor is started by an external device. The lifting motor drives the threaded rod to rotate. The rotating threaded rod causes the bracket to rise. When the bracket rises, it lifts the sealing cover. When the sealing cover rises to a certain height, the gear of the sealing cover will engage with the rack of the support frame. As the sealing cover continues to rise, the gear will rotate under the action of the rack, so that the sealing cover turns and tilts, which is convenient for repairing the stirring mechanism.
