Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a petrochemical reaction vessel that is easy to clean. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. Petrochemicals refer to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. In petrochemical operations, reaction vessels are often used to provide the reaction site for petrochemical reactions.

[0003] The existing reactors can basically meet the needs of use, but there are still some shortcomings: when it is necessary to clean the inside of the reactor, the most common cleaning method is to manually inject a large amount of cleaning water into the reactor body 1. However, this method wastes a lot of water resources, and the cleaning time is not short, and the cleaning effect needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a petrochemical reaction vessel that is easy to clean, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A petrochemical reaction vessel that is easy to clean includes a vessel body and a stirring rod installed inside the vessel body. Several stirring blades are arranged radially and equidistantly on the stirring rod. A feed inlet and a discharge outlet are respectively provided at the top and bottom of the vessel body. A liquid inlet pipe is inserted through the top of the vessel body. A liquid inlet pipe is provided at the top end of the liquid inlet pipe. The bottom end of the liquid inlet pipe is fixedly connected to the top end of the stirring rod. A liquid spraying assembly is provided at the insertion end of the liquid inlet pipe. The liquid spraying assembly includes an annular spray pipe. Several liquid distribution pipes are provided between the annular spray pipe and the liquid inlet pipe. Several nozzles are provided on the bottom surface of the annular spray pipe.

[0007] To further realize this utility model, the bottom end of the stirring rod is provided with an inner wall scraping assembly, which includes an "L"-shaped support rod and an arc-shaped scraper. The "L"-shaped support rod is symmetrically arranged on both sides of the stirring rod. The "L"-shaped support rod includes a horizontal section and a vertical section connected vertically. The end of the horizontal section away from the vertical section is fixedly connected to the outer wall of the stirring rod. The end of the horizontal section connected to the vertical section extends toward the inner wall of the vessel. The vertical section extends toward the top of the vessel. The inner side of the arc-shaped scraper is fixedly connected to the vertical section, and the outer side of the arc-shaped scraper is in contact with the inner wall of the vessel.

[0008] To further realize this utility model, a drive assembly is provided on the top of the vessel body. The drive assembly includes a drive box and a motor, a drive gear and a driven gear disposed in the drive box. The infusion tube passes through the drive box. A rotary joint is provided between the top end of the infusion tube and the infusion tube. A bearing is provided for rotatable connection between the infusion tube and the top surface of the vessel body. The driven gear is sleeved on the outer circumference of the infusion tube. The driven gear meshes with the drive gear. The output shaft of the motor passes through the gear hole of the drive gear.

[0009] To further realize this utility model, the shape of the arc-shaped scraper is matched with the shape of the inner wall of the kettle, and the central axis of the arc-shaped scraper is parallel to the stirring rod.

[0010] To further realize this utility model, the liquid separators are arranged in a cross shape.

[0011] To further realize this utility model, the bottom end of the arc-shaped scraper is close to but does not contact the bottom end of the side wall of the vessel, and the top end of the arc-shaped scraper is lower than the bottom end of the nozzle.

[0012] To further realize this utility model, the axis of the nozzle is parallel to the stirring rod.

[0013] To further realize this utility model, the vertical section is parallel to the inner wall of the vessel and parallel to the stirring rod.

[0014] To further realize this utility model, the horizontal section is perpendicular to the stirring rod.

[0015] To further realize this utility model, a number of connecting rods of equal length are evenly arranged between the inner side of the arc-shaped scraper and the vertical section.

[0016] The advantages of this utility model compared to the prior art are as follows:

[0017] This invention delivers cleaning water to the nozzle through the inlet pipe and then into the vessel body via the delivery pipe. The drive assembly rotates the stirring rod and the spraying assembly, allowing the cleaning water sprayed from the nozzle to be evenly sprayed onto the inner wall of the vessel and the stirring blades from all directions. The arc-shaped scraper removes the cleaning water mixed with petroleum materials remaining on the inner wall of the vessel, and the rotating stirring blades also remove the cleaning water mixed with petroleum materials that remains on the surface of the stirring blades. This effectively improves the cleanliness of the vessel body, saves water resources, shortens the cleaning time, and greatly enhances the cleaning effect. Attached Figure Description
