Description

Technical Field

[0001] The utility model relates to the field of hydrolysis equipment, and more specifically, to hydrolysis equipment for producing fluorobenzoyl chloride. Background Art

[0002] Fluorobenzoyl chloride, with the chemical formula C7H4ClFO, is an organic compound. It is usually a colorless to pale yellow liquid. Fluorobenzoyl chloride is mainly used as an important intermediate in organic synthesis and is often used in the synthesis process of drugs, dyes and other fields. It has high reactivity and can undergo condensation reactions with aromatic amines, alcohols, phenols, etc. to generate corresponding amides, esters and other compounds. Fluorobenzoyl chloride is made by chlorination, hydrolysis and distillation of chlorine gas.

[0003] The hydrolysis process is to hydrolyze the product formed by the chlorination of chlorine. The traditional hydrolysis device generally uses a stirring device to stir during hydrolysis, thereby promoting the mixing of the catalyst (generally a solid catalyst), the above products and water. However, the stirring device will have dead corners, and some solid catalyst particles will fall to the bottom corners of the equipment, which are difficult to stir, resulting in poor mixing efficiency (resulting in poor catalytic effect), ultimately affecting the efficiency of hydrolysis and even affecting the subsequent processing.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a hydrolysis device for producing fluorobenzoyl chloride. Utility Model Content

DETAILED DESCRIPTION

[0027] like Figure 1-5 As shown, the utility model provides a hydrolysis device for producing fluorobenzoyl chloride, comprising a hydrolysis tank body 1, a top cover 2 located on the top of the hydrolysis tank body 1, and a load-bearing bracket 3 arranged at the bottom of the hydrolysis tank body 1 to support it, and the load-bearing bracket 3 is equipped with a cast iron counterweight base 17, so as to counterweight the bottom of the equipment and improve the stability of the equipment.

[0028] The hydrolysis equipment for producing fluorobenzoyl chloride also includes: a circulation component 4, which includes a shell 401 connected to the bottom of the top cover 2 through a vertical rod, a water inlet pipe 402 driven by a water pump is interconnected on one side of the shell 401, and a water outlet pipe 405 is interconnected at the bottom of the shell 401. The water inside the hydrolysis tank body 1 is sucked into the shell 401 by the water pump acting on the water inlet pipe 402, and then discharged from the water outlet pipe 405 and re-enters the hydrolysis tank body 1, thereby forming a cycle. A contact chamber 403 for placing a solid catalyst is formed inside the shell 401. When the contact chamber 403 and the water outlet pipe 405 are in use, the top cover 2 is driven to move upward by the lifting component 5, and the top cover 2 drives the circulation component 4 to move upward, thereby opening the top of the hydrolysis tank body 1, adding water and a product formed by chlorination of chlorine gas into the inside thereof, and then putting the solid catalyst into the contact chamber 403, and adding After the entry is completed, the top cover 2 is driven to move downward by the lifting assembly 5, and the top cover 2 enters the hydrolysis tank body 1 downward and closes its top, and then the water is heated by the heating device in the hydrolysis tank body 1, and the operation of the water pump is controlled by the controller, and the water pump acts on the water inlet pipe 402 to suck the water inside the hydrolysis tank body 1 into the shell 401, and then discharged from the water outlet pipe 405 and enters the hydrolysis tank body 1, so that the water and the above-mentioned products are constantly in contact with the solid catalyst, thereby improving the efficiency of hydrolysis, and it is also best to set a blocking net inside the water inlet pipe 402 to prevent the catalyst from flowing back, and a sieve plate 404 is provided between the catalyst and the drain pipe for blocking, and water can pass through the gap on the sieve plate 404, so that the catalyst can circulate and fully contact with the product formed by chlorination of chlorine and water, and the mixing efficiency is better, thereby greatly improving the efficiency of hydrolysis.

[0029] The lifting assembly 5 includes a connecting shell A501 fixed to the side end of the hydrolysis tank body 1, and the end thereof relative to the hydrolysis tank body 1 is open. A screw rod 502 driven by a motor 507 is installed inside the connecting shell A501, and the surface of the screw rod 502 is fixed to the head of the top cover 2 through a connecting rod 506. A rod sleeve 503 is threadedly connected to the outer wall of the screw rod 502, and the rod sleeve 503 and the connecting shell A501 are fixedly connected with guide rails 504 on both sides. The two sides of the rod sleeve 503 are slidably connected in the guide rails 504 through sliders 505, that is, the forward or reverse rotation of the motor 507 is controlled by a controller, and the motor 507 drives the screw rod 502 to rotate clockwise or counterclockwise, the screw rod 502 drives the rod sleeve 503 to move up and down, the rod sleeve 503 drives the slider 505 to move up and down, the slider 505 slides along the guide rail 504 to maintain the up and down linear movement of the rod sleeve 503, and the rod sleeve 503 can drive the top cover 2 to move up and down through the connecting rod 506.

[0030] Furthermore, the shell 401 is L-shaped, which is composed of a transverse portion 4011, a vertical portion 4012 perpendicular to the transverse portion 4011, and an intermediate portion 4013 where the transverse portion 4011 and the vertical portion 4012 intersect. The water inlet pipe 402 is installed on the side end of the transverse portion 4011 away from the vertical portion 4012, and the water outlet pipe 405 is installed at the bottom of the vertical portion 4012. The contact chamber 403 and the sieve plate 404 are both located inside the transverse portion 4011. The setting of the L-shaped shell 401 allows a certain height difference and distance between the water inlet pipe 402 and the water outlet pipe 405 to more comprehensively circulate the water and the above-mentioned products inside the hydrolysis tank body 1. The top of the transverse portion 4011 is provided with an opening for placing a solid catalyst into the contact chamber 403, and a cover body is threadedly connected above the opening, so that the threaded cover can be removed from the shell 401 by rotating it, and the solid catalyst can be placed in the contact chamber 403.

[0031] At the same time, the utility model also designs the sieve plate 404 to be detachable, so as to facilitate replacement when the sieve plate 404 is damaged. The following is the specific detachable structure; a rectangular block 6 is installed at the top of the transverse portion 4011 near the middle portion 4013, and a through groove 7 for the sieve plate 404 to pass through is provided at the top of the transverse portion 4011 away from the vertical portion 4012. The top of the sieve plate 404 is fixedly connected to a rectangular groove seat 9 through a connecting plate 8, and its opening direction faces downward. After the sieve plate 404 is inserted into the transverse portion 4011 through the through groove 7, the rectangular groove seat 9 thereon is also inserted into the rectangular block 6 for limiting the position, and screws 10 are welded on both sides of the top of the rectangular block 6, and through holes 11 for the screws 10 to pass through are provided on both sides of the top of the rectangular groove seat 9, and a nut 12 is threadedly connected to the outer wall of the screw 10.

[0032] When installing the sieve plate 404, first pass the sieve plate 404 through the through slot 7 into the interior of the shell 401 (the top of the sieve plate 404 just seals the through slot 7). At this time, the rectangular slot seat 9 thereon is also inserted into the rectangular block 6, and the screw 10 on the rectangular block 6 also passes through the through hole 11 on the rectangular slot seat 9. Then, turn the nut 12 clockwise to install the nut 12 on the screw 10. The nut 12 moves downward along the screw 10 and slowly rests on the top of the rectangular slot seat 9. The rectangular slot seat 9 can be fixed on the rectangular block 6, and the installation of the sieve plate 404 is completed. Similarly, when disassembling, you only need to turn the nut 12 counterclockwise to remove the nut 12 from the screw 10, and then pull the sieve plate 404 out of the through slot 7 to achieve the disassembly of the sieve plate 404.

[0033] The sieve plate 404 in the present invention is screened by a plurality of circular holes 4041 thereon (the circular holes 4041 are particularly small in size, and are shown larger in the present invention to clearly indicate the structure). The circular holes 4041 thereon may be blocked during use. For this reason, an embedded fixed connection shell B13 is provided on the side end opposite to the middle portion 4013 and the transverse portion 4011. One end of the connection shell B13 located inside the housing 401 is open. The interior of the connection shell B13 is fixedly connected to an electric cylinder 14. The head of the electric cylinder 14 (waterproof) is fixedly connected to the electric cylinder 14. A movable plate 15 is connected, and a plurality of cylinders 16 having the same number as the circular holes 4041 and being on the same straight line are fixedly connected on the surface of the movable plate 15. When blockage occurs, the movable plate 15 is driven by the electric cylinder 14 to move so that the cylinders 16 thereon are inserted into the circular holes 4041 to push out the blockage inside, thereby clearing the blockage and continuing to use the device. It should be noted that the shell 401 is mounted on the vertical rod at the bottom of the top cover 2 by screws, and the shell 401 needs to be removed from the device regularly to clean the inside.
