Description

Technical Field

[0001] The utility model relates to the technical field of temperature and pressure control devices, and more specifically, to a temperature and pressure control device for a reactor used in the production of an anti-caking agent for high-tower fertilizers. Background Art

[0002] Anti-caking agents are important materials for moisture-proofing and anti-caking of powdered and granular materials during storage and transportation. The main container used in the production of anti-caking agents is the reactor. During the reactor processing, the temperature and pressure of the reactor need to be precisely controlled. Too high or too low temperature and pressure will affect the reaction effect and even cause irreversible serious consequences.

[0003] The pipelines of the existing mechanism are mainly connected by flanges during application. In actual application, the flanges are prone to leakage problems, and when the existing pipelines are connected, impurities will remain in the temperature and pressure pipelines, causing pipeline blockage.

[0004] After searching, the Chinese patent with authorization announcement number CN219308690U discloses a temperature and pressure control device for a reactor for producing anti-caking agents for high-tower fertilizers. The structure connects the temperature control tube and the pressure control tube of the reactor, and adopts a connection control mechanism with high sealing performance to realize the connection of the temperature and pressure control device, and then cooperates with a detachable filter assembly to realize filtering of the passing material. The threaded block is connected to the internal thread to realize sealing of the end of the filter hole. The outer diameter of the filter tube is matched with the filter hole to achieve sealing. At the same time, the material passes through the open side of the filter tube to achieve filtration. During maintenance, the threaded block is directly turned to remove the filter tube to realize cleaning of the filter assembly. The structure is simple and easy to maintain.

[0005] However, in actual use, this structure seals the end of the filter hole by connecting the threaded block with the internal thread, which easily causes leakage in the threaded block and the thread groove under high pressure, affecting the reliability and durability of the seal.

[0029] Working principle of this utility model:

[0030] The present invention is a temperature and pressure control device for a reactor for producing an anti-caking agent for high-tower fertilizer. When the device is in use, the temperature and pressure of the reactor are controlled by a temperature and pressure controller. Automatic adjustment is achieved by utilizing the principle of thermal expansion and contraction of a temperature-sensitive fluid and the incompressibility of a liquid. This device belongs to the prior art and is not described in detail in this technical solution. First, the sealing ring 5 on one side of the first flange plate 4 is inserted into the sealing groove 7 provided on the surface of the second flange plate 6, and then fixed with bolts, thereby realizing the connection between the filter box 8 and the temperature control tube 2 and the pressure control tube 3 respectively, thereby facilitating installation and maintaining a close fit of the sealing surfaces, thereby ensuring a sealing effect. Subsequently, during use, filtration is performed through the first filter element 22 and the second filter element 23 inside the filter box 8. Both the first filter element 22 and the second filter element 23 are made of ceramic filter elements. The first filter element 22 is a coarse filter layer for removing large particles of impurities, while the second filter element 23 is a fine filter layer, thereby further improving the filtration accuracy, thereby effectively filtering, thereby preventing impurities from entering the reactor body of the temperature and pressure controller, thereby enhancing safety.

[0031] When it is necessary to disassemble and replace the first filter element 22 and the second filter element 23 inside, first pull the U-shaped block 21 to both sides of the filter box 8 to drive the U-shaped block 21 to separate from the filter box 8 and the limit groove 20. At this time, the spring 14 releases pressure, thereby resetting and driving the cover plate 15 to move upward. The cover plate 15 drives the connecting blocks 19 on both sides to move upward inside the connecting frame 18. At the same time, the sealing strip 17 moves inside the fixed groove 16. Then, the staff drives the cover plate 15 to continue to move upward, thereby driving the connecting block 19 to separate from the connecting frame 18, thereby removing the cover plate 15, and then pulling the inner mesh cover 12 upward to drive the inner sealing ring 11 to separate from the inner sealing groove 10. The mesh box 9 is separated from the inner mesh cover 12, the inner mesh cover 12 is removed, and then the first filter element 22 and the second filter element 23 are pulled upward to take them out, so that they can be cleaned or replaced. The above steps can be reversed to install, and quick disassembly and assembly are achieved, which is convenient for subsequent maintenance. Filtration is performed through the first filter element 22 and the second filter element 23 inside the filter box 8. The first filter element 22 and the second filter element 23 are both made of ceramic filter elements. The first filter element 22 is a coarse filter layer for removing large particles of impurities, and the second filter element 23 is a fine filter layer, which further improves the filtration accuracy and is convenient for disassembly and replacement to prevent blockage of the temperature control tube 2 and the pressure control tube 3 in the temperature and pressure control.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
