Description

Technical Field

[0001] This utility model belongs to the technical field of sulfuryl fluoride preparation equipment, specifically a reactor for preparing sulfuryl fluoride. Background Technology

[0002] Thionyl fluoride is an inorganic compound that is a colorless, odorless, non-flammable, and toxic gas at room temperature. It possesses broad-spectrum fumigation and bactericidal properties. A reactor is typically used in the preparation of thioyl fluoride.

[0003] Existing reactors for preparing sulfuryl fluoride suffer from uneven catalyst distribution, which prevents sulfur dioxide and fluorine from fully contacting the catalyst, resulting in incomplete reaction between sulfur dioxide and fluorine and reduced preparation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a reactor capable of fully reacting to prepare thioacryl fluoride, thereby addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a reactor for preparing thioyl fluoride is provided, comprising a base frame, an outer barrel fixedly connected to the top of the base frame, a reaction cylinder fixedly connected inside the outer barrel, a bearing fixedly connected to the inner side of the reaction cylinder, a rotating frame fixedly connected to the inner side of the bearing, the rotating frame comprising an outer ring fixedly connected to the inner side of the bearing, connecting rods fixedly connected to the upper and lower sides of the inner side of the outer ring, an inner ring fixedly connected to the end of the connecting rod away from the outer ring, a connecting block fixedly connected to the outer side of the inner ring, and a spiral column fixedly connected between the outer ring and the connecting block.

[0006] Optionally, the base frame includes support columns, the lower part of which is fixedly connected to anti-slip blocks, and the support columns are fixedly connected to each other.

[0007] Optionally, the outer barrel includes a barrel body fixedly connected to the top of the support column, an outlet pipe fixedly connected to the right side of the lower outer side of the barrel body, an inlet pipe fixedly connected to the left side of the upper outer side of the barrel body, and a fixed cylinder fixedly connected to the upper side of the inner side of the barrel body.

[0008] Optionally, the reaction cylinder includes a cylinder body fixedly connected to the lower part of the fixed cylinder, heat dissipation fins fixedly connected to the outer side of the cylinder body, a fixed groove provided on the inner side of the cylinder body, an air inlet pipe fixedly connected to the lower part of the cylinder body, an air outlet pipe fixedly connected to the top of the cylinder body, a motor fixedly connected to the middle of the top of the cylinder body, a rotating shaft fixedly connected to the output end of the motor, and the rotating shaft fixedly connected to the inner ring.

[0009] Optionally, the bearing includes an outer ring fixedly connected to the inner side of the cylinder, a ball movably connected to the inner side of the outer ring, and an inner ring movably connected to the outer side of the ball.

[0010] Optionally, the positions of adjacent connecting blocks are staggered.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting a rotating frame, allows the potassium fluoride particles on the outside of the spiral column to fully contact sulfur dioxide and fluorine gas. During use, cold water is introduced into the tank through the inlet pipe. After the tank is full of cold water, the outlet pipe is opened to allow the cold water inside the tank to circulate, absorbing the heat generated by the reaction and lowering the temperature of the sulfur dioxide and fluorine gas. This also reduces the temperature of the sulfuryl fluoride produced by the reaction, preventing its decomposition due to high temperatures. Then, sulfur dioxide and fluorine gas are introduced into the cylinder through two inlet pipes to carry out the reaction. Simultaneously, the reaction is initiated by... The motor causes the rotating shaft to rotate the inner ring, which in turn drives the connecting rod to rotate the outer ring and the spiral column. Because the spiral column has a spiral structure, the potassium fluoride particles on the outside of the spiral column can fully contact sulfur dioxide and fluorine gas. The rotation of the spiral column further ensures that the potassium fluoride particles on the outside of the spiral column can fully contact sulfur dioxide and fluorine gas. In addition, the positions of the upper and lower adjacent connecting blocks are staggered, so that the upper and lower adjacent spiral columns are staggered, which again ensures that the spiral column can fully contact sulfur dioxide and fluorine gas, making the reaction more thorough and thus improving the preparation efficiency.

[0025] Reference Figures 1 to 6The present invention will now be described. The reactor for preparing thioyl fluoride includes a base frame 1, an outer barrel 2 fixedly connected to the top of the base frame 1, a reaction cylinder 3 fixedly connected inside the outer barrel 2, a bearing 4 fixedly connected to the inner side of the reaction cylinder 3, and a rotating frame 5 fixedly connected to the inner side of the bearing 4. The rotating frame 5 includes an outer ring 503 fixedly connected to the inner side of the bearing 4. Connecting rods 502 are fixedly connected to the upper and lower sides of the inner side of the outer ring 503. The connecting rods 502 are used to connect the inner ring 501 and the outer ring 503. The end of the connecting rod 502 away from the outer ring 503 is fixedly connected to the inner ring 501. A connecting block 505 is fixedly connected to the outer side of the inner ring 501. A spiral column 504 is fixedly connected between the outer ring 503 and the connecting block 505. The spiral column 504 has a spiral structure, and potassium fluoride particles are attached to the outer side of the spiral column 504. Potassium fluoride is used as a catalyst for the reaction. During use, cold water is introduced into the barrel 201 through the water inlet pipe 203. After filling the container 201 with cold water, the outlet pipe 202 is opened to allow the cold water inside the container 201 to circulate, absorbing the heat generated by the reaction and lowering the temperature of sulfur dioxide and fluorine gas. This also reduces the temperature of the sulfuryl fluoride produced by the reaction, preventing its decomposition due to high temperatures. Then, sulfur dioxide and fluorine gas are introduced into the container 301 through two inlet pipes 304 for the reaction. Simultaneously, the motor 307 is started, causing the rotating shaft 305 to rotate the inner ring 501, which in turn drives the connecting rod 502, causing the outer ring 503 to rotate the spiral column 504. Because the spiral column 504 has a spiral structure, the potassium fluoride particles on its outer side can fully contact the sulfur dioxide and fluorine gas. Furthermore, the rotation of the spiral column 504 further ensures sufficient contact between the potassium fluoride particles and the sulfur dioxide and fluorine gas, resulting in a more thorough reaction and improved preparation efficiency.

[0026] In another embodiment of this utility model, the base frame 1 includes a support column 101, and an anti-slip block 103 is fixedly connected to the lower part of the support column 101. The anti-slip block 103 is made of rubber material and has a certain anti-slip function, which facilitates the stable placement of the outer bucket 2. A connecting column 102 is fixedly connected between the support columns 101. The connecting column 102 is used to connect adjacent support columns 101, making the base frame 1 more stable.

[0027] In another embodiment of this utility model, the outer bucket 2 includes a bucket body 201 fixedly connected to the top of the support column 101. A water outlet pipe 202 is fixedly connected to the lower right side of the outer side of the bucket body 201 for discharging cold water after use. A water inlet pipe 203 is fixedly connected to the upper left side of the outer side of the bucket body 201 for the entry of cold water. A fixed cylinder 204 is fixedly connected to the upper inner side of the bucket body 201. Cold water is introduced into the bucket body 201 through the water inlet pipe 203. After the bucket body 201 is filled with cold water, the water outlet pipe 202 is opened to allow the cold water inside the bucket body 201 to circulate, so as to absorb the heat generated by the reaction and reduce the temperature of sulfur dioxide and fluorine gas. At the same time, it can also reduce the sulfuryl fluoride generated by the reaction and prevent the sulfuryl fluoride from decomposing due to high temperature.

[0028] In another embodiment of this utility model, the reaction cylinder 3 includes a cylinder 301 fixedly connected to the lower part of the fixed cylinder 204. Heat dissipation fins 302 are fixedly connected to the outer side of the cylinder 301. The heat dissipation fins 302 are used to increase the contact area with cold water, facilitating rapid cooling of the reaction cylinder 3. A fixing groove 303 is provided on the inner side of the cylinder 301 for fixing the outer ring 401. An air inlet pipe 304 is fixedly connected to the lower part of the cylinder 301 for using carbon dioxide... Sulfur and fluorine gas enter, and an outlet pipe 306 is fixedly connected to the top of the cylinder 301. The outlet pipe 306 is used to discharge the sulfuryl fluoride generated by the reaction. A motor 307 is fixedly connected to the middle of the top of the cylinder 301. A rotating shaft 305 is fixedly connected to the output end of the motor 307. The rotating shaft 305 is fixedly connected to the inner ring 501. Starting the motor 307 causes the rotating shaft 305 to drive the inner ring 501 to rotate, thereby driving the connecting rod 502 to drive the outer ring 503 to drive the spiral column 504 to rotate.

[0029] In another embodiment of this utility model, the bearing 4 includes an outer ring 401 fixedly connected to the inner side of the cylinder 301, a ball 402 movably connected to the inner side of the outer ring 401, and an inner ring 403 movably connected to the outer side of the ball 402. The ball 402 can roll between the outer ring 401 and the inner ring 403, so that the outer ring 401 and the inner ring 403 can rotate relative to each other, making it easier for the rotating frame 5 to rotate.

[0030] In another embodiment of this utility model, the positions of the upper and lower adjacent connecting blocks 505 are staggered, so that the upper and lower adjacent spiral columns 504 are staggered, which is used to ensure that the spiral column 504 is in full contact with sulfur dioxide and fluorine gas.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
