Description

Technical Field

[0001] This utility model relates to the field of potassium sulfate reactor technology, and more specifically, to a modular potassium sulfate reactor that is easy to maintain. Background Technology

[0002] A potassium sulfate reactor is a chemical equipment used to produce potassium sulfate. It converts potassium chloride and sulfuric acid into potassium sulfate through a specific chemical reaction. Potassium sulfate has a wide range of applications in agriculture, industry, and medicine. In practical use, it has advantages such as high temperature and corrosion resistance, stable structure, good sealing performance, and safe use.

[0003] The prior art discloses a Mannheim reactor for potassium sulfate preparation, application number CN202122207851.1. In this utility model, the furnace body is a single unit design, which makes it impossible to separate the combustion structure, stirring reaction structure, and collection structure during maintenance. This results in a narrow operating space, difficulty in troubleshooting, and easy damage to other components, causing inconvenience for the maintenance of this utility model. At the same time, the sulfuric acid feed port and potassium chloride feed port are fixed installations, making it difficult to disassemble, clean, or replace them when needed, thus reducing the practicality of this utility model.

[0038] Working principle:

[0039] When the modular potassium sulfate reactor, which is designed for easy maintenance, needs to be inspected, use tools to remove the bolts, then pull out the two sets of burners 10. After that, open the furnace cover 12, and then use the first control panel to shorten the electric telescopic rod 14. At this time, the lifting plate 16 will move the two sets of collection tanks 18 downwards. When the two sets of collection tanks 18 are moved out of the collection chamber 4, the four sets of mounting screws 17 and four sets of mounting nuts 19 are threaded together. The operator can then manually unscrew the four sets of mounting nuts 19 counterclockwise. After that, the two sets of collection tanks 18 can be disassembled, and the speed regulating electric motor can be removed through the through holes of the two sets of collection tanks 18. Machine 8 is then removed through inspection port 11, and the stirring rake 9 can be disassembled for inspection. After inspection, it is reset.

The two burners 10 are then activated using the second control panel, and the open flame heats the sulfuric acid and potassium chloride inside the reaction chamber 3. The speed-regulating motor 8 is then activated via the speed controller using the second control panel. The output of the speed-regulating motor 8 can rotate the stirring rake 9 through the mounting shaft. The rotating stirring rake 9 agitates the sulfuric acid and potassium chloride. Potassium, and the resulting hydrogen chloride, can be discharged through the hydrogen chloride exhaust pipe. The produced potassium sulfide can enter the interior of two sets of collection tanks 18 through two sets of insertion pipes 20. The collection tanks 18 and the movable frame 13 allow for the disassembly of the stirring reaction structure and collection structure of the furnace body 1, thereby achieving the purpose of classified separation and maintenance. This facilitates the maintenance of the modular potassium sulfate reactor. Simultaneously, when it is necessary to disassemble the two sets of feeding pipes 7, the positioning screws 26 and two sets of fastening nuts 28 are threaded together. The operator can then manually rotate the two sets of fastening nuts 28 counterclockwise to remove them. After pressing the plate 27, two sets of feeding pipes 7 can be removed. At this time, the two sets of feeding pipes 7 can be cleaned, and then two new sets of feeding pipes 7 can be installed. When the four sets of sealing rings 22 are inserted into the four sets of built-in grooves 6 respectively, the plate 27 and the two sets of fastening nuts 28 are clockwise fitted onto the side wall of the positioning screw 26. When the plate 27 contacts the two sets of sealing rings 22 above, the installation of the two sets of feeding pipes 7 is completed. Through the set feeding box 5, the sulfuric acid feeding structure and potassium chloride feeding structure can be disassembled and replaced, which improves the usability of the modular potassium sulfate reactor that is easy to maintain.
