[0001] The utility model relates to the technical field of petroleum additive production, in particular to a reaction kettle for producing petroleum additives. Background Art

[0002] Petroleum additives refer to various chemical substances used in the process of oil extraction, processing and use, such as demulsifiers, water reducers, corrosion inhibitors, scale inhibitors, etc. They can improve oil extraction efficiency, improve the quality of oil products and protect equipment; petroleum additive reactor refers to equipment used in the process of oil processing to manufacture petroleum additives through chemical reactions.

[0003] Due to their physical and chemical properties, petroleum additives are generally sticky. During the production process in the reactor, petroleum additives will inevitably adhere to the inner wall of the reactor, which is not easy to clean. The petroleum additives adhered to the inner wall of the reactor are not easy to discharge, resulting in waste and affecting the subsequent production of petroleum additives. Summary of the invention

[0004] The utility model aims to solve the problem that petroleum additives adhere to a reaction kettle during production and are difficult to clean. The utility model provides a reaction kettle for producing petroleum additives, which can reduce waste of petroleum additives and facilitate cleaning.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figure 1 to Figure 4 As shown, a reactor for producing petroleum additives comprises a shell 1, which is a cylinder with an opening at the lower end, a rotating shaft 2 is rotatably arranged in the shell 1, and a stirring paddle 3 is arranged on the rotating shaft 2; a cleaning piece is also included; a bottom plate 4 is connected to the lower part of the shell 1, and the bottom plate 4 blocks the lower opening of the shell 1, and the cleaning piece comprises a sleeve 5, a driving ring 6 and a cleaning ring 7, the sleeve 5 is a cylinder with openings at both ends and an inner diameter greater than the outer diameter of the shell 1, the sleeve 5 is sleeved outside the shell 1, and the upper and lower ends of the inner wall are connected to the shell 1 through a connecting ring 8, and the connecting ring 8 is a circular plate body; a driving ring 6 movably sleeved outside the shell 1 is arranged in the sleeve 5, and the driving ring 6 is a circular ring body, and the outer ring surface of the driving ring 6 slides in contact with the inner wall of the sleeve 5, and the inner ring surface slides in contact with the inner wall of the sleeve 5. The outer wall of the shell body 1 is touched, and hydraulic cylinders 9 are fixed on the left and right parts of the top surface of the lower connecting ring 8. The piston end of the hydraulic cylinder 9 is connected to the drive ring 6 upward. The cleaning ring 7 is arranged in the shell body 1 and is sleeved on the outside of the rotating shaft 2. The cleaning ring 7 slides up and down in contact with the inner wall of the shell body 1. The left and right parts of the cleaning ring 7 are connected to the drive ring 6 through a steel strand group. The two steel strand groups are in a left-right symmetrical state. The steel strand group on the left side includes steel strand 10 and steel strand 2 11. One end of steel strand 10 is connected to the upper left part of the cleaning ring 7, and the other end passes through the left part of the peripheral wall of the shell 1 and is bent downward to connect the drive ring 6. One end of steel strand 2 11 is connected to the lower left part of the cleaning ring 7, and the other end of steel strand 2 11 passes through the left part of the bottom plate 4 and the left part of the peripheral wall of the shell in sequence, and is bent upward to connect the drive ring 6.

[0023] The top plate of the shell 1 is connected to a feed pipe 12, the upper end of the rotating shaft 2 passes through the top plate of the shell 1 and is driven to rotate by a motor 13, a discharge valve 14 is provided on the bottom plate 4, the bottom plate 4 is a hollow spherical body with an open upper end and a protrusion facing downward, and legs 15 are arranged in an array on the bottom surface of the lower connecting ring 8.

[0024] The cleaning ring 7 is a circular ring body whose outer ring surface slides in contact with the shell 1. The diameter of the inner ring surface of the cleaning ring 7 gradually increases from top to bottom. The lower end of the inner ring surface of the cleaning ring 7 coincides with the lower end of the outer ring surface of the cleaning ring 7. The diameter of the upper end of the inner ring surface of the cleaning ring 7 is greater than the diameter of the circle where the outer end of the stirring paddle 3 is located.

[0025] The bottom plate 4 is higher than the lower end of the shell 1. The left steel strand 11 passes downward through the left part of the bottom plate 4. A through hole 16 is provided on the left part of the bottom plate 4 for the steel strand 11 to pass through. A graphite packing seal 17 is fixed in the through hole 16. The steel strand 11 passes through and slides in contact with the graphite packing seal 17. The graphite packing seal 17 has excellent sealing and wear resistance, and can prevent petroleum additives from flowing out through the through hole 16.

[0026] A through hole 2 18 is provided at the left end of the peripheral wall of the shell 1 on the lower side of the bottom plate 4 for the left-side steel strand 2 11 to pass through, and the through hole 2 18 is an arc-shaped hole protruding downward. A through hole 3 19 is provided at the left end of the peripheral wall of the shell 1 for the left-side steel strand 10 to pass through, and the through hole 3 19 is an arc-shaped hole protruding upward.

[0027] When the driving ring 6 moves downward to an extreme state, the cleaning ring 7 is close to the top surface of the housing 1 , and when the driving ring 6 moves upward to an extreme state, the lower end of the cleaning ring 7 contacts the bottom plate 4 .

[0028] When in use, in the initial state, the cleaning ring is close to the top surface of the shell, the discharge valve 14 is closed, and the motor 13 drives the stirring paddle 3 to stir the petroleum additive in the shell 1. After the production is completed, the discharge valve 14 opens to discharge the material, and the piston end of the hydraulic cylinder 9 on the lower connecting ring 8 extends to drive the driving ring 6 to move upward. When the driving ring 6 moves upward, the steel strand 11 on each steel strand group and one end connected to the driving ring 6 are driven to move upward, and the steel strand 11 and the cleaning ring 7 are connected at one end to move downward, thereby pulling the cleaning ring 7 to move downward. When the cleaning ring 7 moves downward, the steel strand 10 on each steel strand group and the cleaning ring 7 are connected at one end to move downward. One end connected to the driving ring 6 moves upward, and when the cleaning ring 7 moves downward, the lower end of the inner ring surface of the cleaning ring 7 scrapes off the petroleum additives adhered to the inner wall of the shell 1. Since the diameter of the inner ring surface of the cleaning ring 7 gradually increases from top to bottom, and the lower end of the inner ring surface coincides with the lower end of the outer ring surface, it is beneficial to scrape off the petroleum additives on the inner wall of the shell 1. The scraped petroleum additives fall onto the bottom plate 4 and are discharged by the discharge valve 14. Therefore, the utility model can conveniently clean the inner wall of the shell 1. When the driving ring 6 moves downward, the cleaning ring 7 can be pulled upward by the steel strand group. The driving ring 6 is repeatedly driven up and down to repeatedly clean the inner wall of the shell 1.
