Description

Technical Field

[0001] This utility model relates to the field of cyanuric chloride production technology, specifically to a cyanuric chloride clean sublimation device. Background Technology

[0002] Cyanide is an important organic chemical intermediate, appearing as a white crystalline powder with a pungent odor. Its molecular structure is a triazine ring skeleton, with three highly reactive chlorine atoms that readily undergo substitution reactions with amino, hydroxyl, and other groups. Currently, cyanide sublimation crystallization uses low-temperature cold air to directly cool and sublimate the synthesized cyanide. However, due to the low specific heat capacity of air and the large air consumption, it is difficult to recover the excess chlorine gas used for polymerization protection. It can only be absorbed and treated with liquid alkali, which consumes a large amount of liquid alkali and is costly. Furthermore, the crystallization method of direct contact between cold air and the material results in products with small particle size, large specific surface area, and low bulk density, which cannot meet the requirements of some customers. Utility Model Content

[0003] The purpose of this invention is to provide a clean cyanuric chloride sublimation device to solve the problems mentioned in the background art. The current cyanuric chloride sublimation crystallization method uses low-temperature cold air to directly cool and sublimate the synthesized cyanuric chloride. Due to the low specific heat capacity of air and the large amount of air used, it is difficult to recover the excess chlorine gas used for polymerization protection. It can only be absorbed and treated by liquid alkali, which consumes a lot of liquid alkali and has a high cost. Secondly, the crystallization method of direct contact between cold air and material for cooling and sublimation results in products with small particle size, large specific surface area, and low bulk density, which cannot meet the requirements of some customers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cyanogen trichloride clean sublimation device, comprising a machine body, wherein a first sublimation roller and a second sublimation roller are respectively provided on both sides of the upper end of the machine body, a main shaft tube is provided through the middle of the inner part of the first and second sublimation rollers, the two ends of the main shaft tube are respectively through the side walls of the machine body, a sealed bearing is provided between the main shaft tube and the machine body, a rotary joint is provided at the middle of the two ends of the main shaft tube, a power motor is provided at one end of the main shaft tube outside the machine body, the power motor is connected to the first and second sublimation rollers respectively through a belt drive system, an air distribution pipe is provided inside the machine body below the first and second sublimation rollers, an output pipe is provided at the middle of the lower end of the machine body, and a scraper is provided inside the machine body outside the lower end of the first and second sublimation rollers.

[0005] Preferably, the two main shaft tubes are rotatably connected to the machine body through the sealed bearings. A closed section is provided in the middle of the interior of the main shaft tube. A through hole is provided on the side wall of the main shaft tube outside the closed section. The inner cavity of the main shaft tube outside the closed section is connected to the inner cavities of the first deposition roller and the second deposition roller through the through hole.

[0006] Preferably, the upper ends of the two feeding scrapers are rotatably connected to the machine body via a rotating shaft, and the lower ends of the two feeding scrapers respectively abut against the outer surfaces of the first and second deposition rollers. An adjusting push rod is provided between the middle position of the outer surfaces of the two feeding scrapers and the machine body.

[0007] Preferably, a discharge hood is connected between the lower end of the machine body and the output pipe, an output spiral is provided inside the output pipe, a discharge motor is provided on one side of the output pipe, and the power end of the discharge motor is connected to the output spiral.

[0008] Preferably, the air distribution pipe is S-shaped and arranged inside the machine body, and the lower wall of the air distribution pipe has air distribution holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the use of a dynamic sublimator to indirectly cool and sublimate the polymerized product completely eliminates the use of cold air, avoiding the problem of high consumption and high cost of liquid alkali due to the low specific heat capacity of air. The crystallization method of indirect contact cooling and sublimation of materials results in products with larger particle size, smaller surface area, and higher bulk density, meeting customer requirements.

The two ends of the main shaft tube 4 penetrate the two side walls of the body 1. A sealed bearing 5 is provided between the main shaft tube 4 and the body 1. A rotary joint 6 is provided at the middle of both ends of the main shaft tube 4. A power motor 7 is provided at one end of the main shaft tube 4 and outside the body 1. The power motor 7 is connected to the first deposition roller 2 and the second deposition roller 3 respectively via a belt drive system. An air distribution pipe 8 is provided inside the body 1 and below the first deposition roller 2 and the second deposition roller 3. An output pipe 9 is provided at the middle of the lower end of the body 1. A scraper 10 is provided inside the body 1 and outside the lower end of the first deposition roller 2 and the second deposition roller 3.

[0018] In operation, the external cooling source is connected to one end of the main shaft tube 4 via rotary joint 6, and the cooling source recovery pipe is connected to the other end of the main shaft tube 4 via rotary joint 6. Coolant flows through the main shaft tube 4 to the interior of the first and second deposition rollers 2 and 3, reducing the temperature of their outer surfaces. Melamine chloride gas is introduced into the machine body 1 through the gas distribution pipe 8, distributing the melamine chloride throughout the machine body 1. Melamine chloride is distributed to the first deposition roller 2... The first and second deposition rollers 2 and 3 are pre-cooled and crystallized on their outer surfaces. The power motor 7 drives the first and second deposition rollers 2 and 3 to rotate under the support of the sealed bearing 5 through the belt drive system. A scraper 10 is set at the lower end of the first and second deposition rollers 2 and 3. Through the rotation of the first and second deposition rollers 2 and 3, the scraper 10 scrapes and discharges the cyanuric chloride crystals crystallized on the outer surfaces of the first and second deposition rollers 2 and 3. The discharged material is output to the outside through the output pipe 9.

The inner cavity of the main shaft tube 4 outside the closed section 11 is connected to the inner cavity of the first deposition roller 2 and the second deposition roller 3 through the through hole 12. The closed section 11 in the middle of the main shaft tube 4 prevents the cooling source from flowing directly through the main shaft tube 4. Instead, it flows into the interior of the first deposition roller 2 and the second deposition roller 3 through the through hole 12 at one end of the main shaft tube 4 to cool the first deposition roller 2 and the second deposition roller 3. The coolant that has completed the heat exchange flows back into the interior of the main shaft tube 4 through the through hole 12 at the other end of the main shaft tube 4 and is then output to the outside.

[0020] The upper ends of the two feeding scrapers 10 are rotatably connected to the machine body 1 via a rotating shaft. The lower ends of the two feeding scrapers 10 respectively abut against the outer surfaces of the first deposition roller 2 and the second deposition roller 3. An adjusting push rod 13 is provided between the middle position of the outer surface of the two feeding scrapers 10 and the machine body 1. By adjusting the push rod 13, the feeding scrapers 10 are driven to rotate inside the machine body 1, thereby adjusting the fit between the feeding scrapers 10 and the outer surfaces of the first deposition roller 2 and the second deposition roller 3.

A discharge motor 16 is provided on one side of the output pipe 9. The power end of the discharge motor 16 is connected to the output spiral 15. The discharge hood 14 collects the discharged material and drops it into the output pipe 9. The discharge motor 16 drives the output spiral 15 to rotate inside the output pipe 9. Through the relative rotation of the output spiral 15 and the output pipe 9, the material inside the output pipe 9 is output to the outside.

[0022] The gas distribution pipe 8 is S-shaped and installed inside the body 1. The lower wall of the gas distribution pipe 8 is provided with a gas distribution hole 17. The cyanuric chloride gas inside the gas distribution pipe 8 is distributed into the interior of the body 1 through the gas distribution hole 17.
