[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] An enamel reactor for producing chloropropionyl chloride according to a preferred embodiment of the present invention will be described in detail below.

[0034] Embodiment 1, as Figure 1-Figure 8 As shown, it includes a reactor body 1, and a cleaning mechanism 2 is arranged inside the reactor body 1;

[0035] The cleaning mechanism 2 includes a stirring rod 201 arranged inside the reactor body 1, the stirring rod 201 can rotate inside the reactor body 1, the two sides of the stirring rod 201 are fixedly connected with connecting rods 202, cleaning plates 203 are arranged on both sides of the stirring rod 201, the cleaning plates 203 are fixedly connected with the connecting rods 202, both sides of the cleaning plates 203 are fixedly connected with connecting frames 204, a plurality of cleaning holes 205 are provided on the side of the cleaning plates 203 close to the reactor body 1, a sliding groove is provided on the side of the cleaning plates 203 close to the connecting frame 204, a sliding plate 206 is slidably connected inside the sliding groove, and the sliding plate 206 is slidably connected inside the sliding groove. 6 is provided with a through hole slightly smaller than the aperture of the cleaning hole 205. When the sliding plates 206 are closed together, the through hole can be moved to the inside of the cleaning hole 205. The sliding plates 206 are provided with several groups. A scraper 207 is provided inside the connection frame 204. A matching plate 208 is fixedly installed on the side of the scraper 207 close to the connection frame 204. A matching inclined surface is provided on the side of the matching plate 208 opposite to the sliding plate 206. Slide blocks 209 are slidably installed on both upper and lower sides of the inner wall of the connection frame 204. The slide block 209 is rotatably connected to the scraper 207. A connecting spring 210 is fixedly installed between the sliding plate 206 and the cleaning plate 203.

[0036] A linkage rod 3 is fixedly installed on the top of the scraper 207, a driving ring 4 is arranged on the surface of the stirring rod 201, the driving ring 4 can rotate on the surface of the stirring rod 201, an elastic rope 5 is fixedly installed on the surface of the driving ring 4, the elastic rope 5 is fixedly connected to the linkage rod 3, the interior of the stirring rod 201 is arranged as a hollow structure, and a water pipe 6 is fixedly connected to the top of the stirring rod 201;

[0037] After the reactor manufactures chloropropionyl chloride, when it is necessary to clean the residue inside the reactor, the acidic cleaning agent and the alkaline cleaning agent are mixed with water, and then the mixed cleaning agent is connected to the water pipe 6 through a water pipe, and the cleaning agent enters the cleaning plate 203 through the stirring rod 201 and the connecting rod 202, and flows out through the cleaning hole 205, so as to rinse and dissolve the residue on the inner wall of the reactor body 1. At this time, due to the large aperture of the cleaning hole 205, the flow rate of the water flow will be reduced, so as to more gently rinse the inner wall of the reactor body 1. When the cleaning agent flows out, when the stirring rod 201 rotates counterclockwise, the stirring rod 201 drives the cleaning plate 203 to rotate through the connecting rod 202, and at the same time, the scraper 207 is fitted with the inner wall of the reactor body 1. Under the rotation of the stirring rod 201, the scraper 207 scrapes off the residue on the inner wall of the reactor body 1. At the same time, since the end of the scraper 207 is set to be round, when it contacts a relatively hard When there is residue, the scraper 207 will be pushed to move inside the connecting frame 204. At the same time, when the scraper 207 moves, it will drive the matching plate 208 to move synchronously, so that the matching plate 208 fits with the inclined surface opened on one side of the sliding plate 206 when moving, thereby driving the sliding plate 206 to move inward and close together, and at the same time squeeze the connecting spring 210, so that the connecting spring 210 shrinks due to elastic potential energy, so that the through hole blocks the cleaning hole 205, so that the cleaning agent flows out from the through hole. At this time, due to the reduction of the aperture, the flow rate of the water flow will increase, thereby enhancing the impact force, so as to wash and dissolve the stubborn residue. When the thickness of the residue is small, the connecting spring 210 can push the sliding plate 206 to reset. At the same time, according to the thickness of the residue, the number of through holes can be adjusted, which can prevent the flow rate of the water flow from being too large when washing some thin residues, generating a large impact force, thereby causing the enamel coating to peel off or cause cracks to appear;

[0038] Through the cooperation of the scraper 207, the residue on the inner wall of the reactor body 1 can be scraped off, thereby greatly shortening the efficiency of cleaning the reactor. Since the residue washed off may adhere to the surface of the scraper 207, when the stirring rod 201 rotates clockwise, it can drive the driving ring 4 to rotate, thereby pulling the elastic rope 5 to wrap around the surface of the driving ring 4, and at the same time, the elastic rope 5 pulls the linkage rod 3. At the same time, since the scraper 207 is rotatably connected to the slider 209, the scraper 207 rotates relatively, so that the cleaning agent can rinse the scraper 207 during rinsing, thereby preventing the residue from adhering to the surface of the scraper 207 and affecting the scraping and rinsing, thereby improving the efficiency and effect of cleaning the reactor. Furthermore, the rotation connection between the scraper 207 and the slider 209 has a certain friction force. When the scraper 207 scrapes the inner wall of the reactor, it will not easily rotate due to the action of the friction force.

[0039] Embodiment 2, as Figure 1-Figure 3As shown, a driving mechanism 7 is provided at the bottom of the reactor body 1, and the driving mechanism 7 includes a driving box 71 fixedly installed at the bottom of the reactor body 1, a driving gear 72 is rotatably installed on the inner top of the driving box 71, a half gear 73 is rotatably installed on the inner top of the driving box 71 and located on one side of the driving gear 72, a driving disc 74 is rotatably installed on the inner top of the driving box 71, a plurality of driving teeth 75 are fixedly installed on the inner wall of the driving disc 74, and the driving teeth 75 are meshed with the driving gear 72, a driving motor 76 is fixedly installed at the bottom of the driving box 71, an output end of the driving motor 76 is fixedly connected to the half gear 73, the driving disc 74 is fixedly connected to the output end of the driving motor 76, and the driving gear 72 is fixedly connected to the bottom of the stirring rod 201;

[0040] The drive motor 76 is arranged to drive the drive disk 74 and the half gear 73 to rotate synchronously. Due to the arrangement of the drive teeth 75 and the half gear 73, when the half gear 73 rotates, it can mesh with the drive gear 72, driving the drive gear 72 to rotate one circle clockwise. When the half gear 73 rotates to the toothless side, the drive gear 72 is no longer meshed with the half gear 73. At this time, the drive teeth 75 on the inner wall of the drive disk 74 mesh with the drive gear 72. At this time, the drive gear 72 will be driven by the drive disk 74 to rotate one circle counterclockwise, so that the drive gear 72 can drive the stirring rod 201 to rotate clockwise and counterclockwise, so that when the stirring rod 201 drives the scraper 207 to rotate, some more stubborn residues can be scraped off alternately, and the stubborn residues can be effectively scraped off.

[0041] Embodiment three, as Figure 8 As shown, the driving ring 4 includes a slotted interior, a limit block 8 is rotatably mounted inside the driving ring 4, an elastic block 9 is fixedly mounted on one side of the limit block 8, a ratchet 10 is fixedly mounted on the surface of the stirring rod 201, the ratchet 10 cooperates with the limit block 8, and the driving ring 4 is rotatably connected to the top of the reactor body 1;

[0042] When the stirring rod 201 rotates counterclockwise through the set ratchet 10, the ratchet 10 cooperates with the limit block 8, and the ratchet 10 pushes the limit block 8 to drive the drive ring 4 to rotate. At this time, the elastic rope 5 will not be entangled. When the stirring rod 201 rotates clockwise, the ratchet 10 will push the limit block 8 to rotate to one side due to the inclined surface. At this time, when the stirring rod 201 rotates, it will drive the elastic rope 5 to wrap around the surface of the drive ring 4, so that the elastic rope 5 can pull the scraper 207 to rotate.

[0043] Embodiment 4, as Figure 1-Figure 4 As shown, the connecting frame 204 has an extension slot 11 on one side away from the cleaning plate 203, and the extension slots 11 are provided with the same number of matching plates 208;

[0044] The extended groove 11 can be provided to enable the scraper 207 to drive the matching plate 208 to move out when rotating, so as to facilitate the rotation of the scraper 207.

[0045] Embodiment 5, as Figure 1-Figure 2 As shown, the bottom of the reactor body 1 is fixedly installed with support legs 12, and the support legs 12 are arranged in a ring in a plurality of groups. One side of the reactor body 1 is fixedly connected with a discharge pipe 13;

[0046] The reactor body 1 can be supported by the support legs 12 , and the residues after flushing and dissolution can be discharged by the discharge pipe 13 .

[0047] Embodiment six, as Figure 1 and Figure 5 As shown, vertical grooves are provided on both upper and lower sides of the inner wall of the connection frame 204, the slider 209 is slidably connected to the vertical grooves, and the scraper 207 is made of rubber material with certain toughness;
