Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a petrochemical reaction kettle. Background Art

[0002] The petrochemical industry, referred to as petrochemicals, generally refers to the chemical industry that uses oil and natural gas as raw materials. It has a wide range and many products. Crude oil is cracked, reformed and separated to provide basic raw materials such as ethylene, propylene, butylene, butadiene, benzene, toluene, xylene, naphthalene, etc. The broad understanding of the reactor is a container for physical or chemical reactions. 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 petroleum, chemical, rubber, pesticide, dye, medicine and food and other fields.

[0003] The "reactor for petrochemical industry" disclosed in patent publication number "CN215277294U" includes a petrochemical reaction mechanism, and the petrochemical reaction mechanism includes a petrochemical reactor body, a first partition is fixedly installed at the top of the inside of the petrochemical reactor body, a motor is fixedly installed at the top of the first partition, a first rotating rod is fixedly installed at one end of the motor, and the first rotating rod passes through the first partition through a rotating shaft. The utility model is provided with a first rotating rod, a second rotating rod, a first bevel gear, a second bevel gear, a connecting rod, a first stirring paddle and a second stirring paddle. When the staff turns on the switch of the device, one end of the motor starts to rotate, and the second rotating rod is driven to rotate through the first rotating rod, the first bevel gear and the fixed rod. At this time, the rotation directions of the first stirring paddle and the second stirring paddle are opposite, so that the petroleum raw materials inside the petrochemical reactor body are fully stirred, thereby improving the production efficiency of the device.

[0004] In view of the above problems, although the device can achieve a relatively good stirring effect, its first stirring paddle and the second stirring paddle are located at the bottom of the main body of the petrochemical reactor. When some catalysts are added, they are often added to the upper or lower layer of the liquid of the crude oil, and then the stirring paddles are rotated to rotate the crude oil liquid, so that the raw material liquids of the upper and lower layers are mixed and exchanged. However, this process takes a long time, and the crude oil has a certain viscosity, which will increase the mixing time of each layer of liquid.

[0005] To this end, the utility model provides a petrochemical reactor to solve the above-mentioned problem. The servo motor drives the second pulley to rotate, and then the first transmission belt drives the first pulley to rotate, and then the first rotating shaft rotates, and then the concave frame rotates to drive the reactor shell to rotate so that the internal petroleum raw liquid rolls without moving, so that the layers of liquid can be quickly mixed and exchanged to achieve the stirring effect.
