Description

Technical Field

[0001] The utility model relates to the technical field of reactors, and more specifically, to a stirring, lifting and limiting device for a reactor. Background Art

[0002] A reactor is a container used to carry out physical or chemical reactions. Available in a variety of materials, including stainless steel, carbon steel, and glass-lined, reactors are widely used in industries such as petrochemicals, rubber, pesticides, dyes, and pharmaceuticals, completing processes such as sulfonation, nitration, hydrogenation, and polymerization. Traditional reactor stirring devices utilize fixed-point stirring, making it difficult to fully stir the mixture at different heights within the reactor by raising and lowering it. This results in poor stirring performance and incomplete stirring of the mixture within the reactor.

[0003] After searching, the Chinese patent with announcement number CN216172267U discloses a stirring device for a reactor that can be lifted and stirred. Through a motor, a connecting shaft, a disc, a connecting rod one, a connecting rod two and a sleeve, the lifting rod and the stirring rod as well as the stirring rod one and the stirring rod two are driven to perform spiral vertical lifting and stirring of the mixture in the reactor body. This solves the problem that the traditional stirring device for a reactor has difficulty in fully stirring the mixture at different heights in the reactor by lifting and lowering, resulting in poor stirring effect of the stirring device. It can automatically perform spiral lifting and stirring of the mixture at different heights in the reactor, thereby improving the stirring effect of the stirring device on the mixture in the reactor.

[0004] When the stirring device for the above-mentioned reactor is in use, the rotating disk drives the connecting rod to perform eccentric movement, thereby causing the stirring mechanism to move up and down. However, during the up and down movement, since the stirring mechanism is located inside the reactor body, it is inconvenient to observe the position of the stirring mechanism, and the use effect is poor. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a stirring lifting and limiting device for a reactor, which aims to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stirring, lifting and limiting device for a reactor, comprising a reactor body and a reactor cover, the bottom end of the reactor cover extends into the interior of the reactor body, the outer side of the reactor cover is fixedly connected to a side plate, the bottom end of the side plate is fixedly installed with a hydraulic cylinder, the bottom end of the hydraulic cylinder is fixedly connected to a support frame, and the support frame is fixedly installed on the outer side of the reactor body, the top end of the support frame is fixedly connected to two scales, and the two facing sides of the scales are each provided with a limiting assembly, and the two limiting assemblies each include a limiting plate, a sliding rod and an indicator plate, and a stirring assembly is provided on the reactor cover, and the stirring assembly includes a motor, a rotating shaft and a plurality of stirring rollers.

[0007] Furthermore, the two facing sides of the limit plates are fixedly connected to the kettle cover, the bottom ends of the two slide rods respectively pass through the two limit plates and are fixedly connected to the support frame, and the two facing sides of the indicator plates are respectively fixedly connected to the two limit plates.

[0009] Furthermore, a top frame is fixedly connected to the top of the reactor body, a gasket is movably provided inside the top frame, and the inner side of the gasket is in contact with the reactor cover.

[0010] It can be seen that in the above technical solution, the sealing between the reactor cover and the reactor body can be improved by the gasket.

[0011] Furthermore, a material guide pipe is fixedly installed on the reactor cover, and two transparent plates are movably provided on the bottom of the material guide pipe, and the two transparent plates are fixedly installed on the reactor body.

[0012] Furthermore, the bottom end of the reactor body is fixedly connected to a discharge pipe, and a solenoid valve is fixedly installed on the discharge pipe.

[0013] It can be seen that in the above technical solution, by opening the solenoid valve, the reactants in the reactor body can be discharged through the discharge pipe.

[0018] 2. In the utility model, when the piston rod on the hydraulic cylinder extends and drives the side plate and the kettle cover to move upward, the kettle cover can drive the material guide pipe to move upward and make the material guide pipe located at the top of the reactor body. Then, new raw materials are added into the material guide pipe, and the material guide pipe guides the raw materials and makes them fall into the reactor body. The reaction of the raw materials can be observed through the two transparent plates. At the same time, the kettle cover can also shield the two transparent plates.
