Description

Technical Field

[0001] The invention relates to the technical field of distillation equipment, in particular to a device for generating waste water during the distillation of ethylene glycol antimony production. Background Art

[0002] The main use of ethylene glycol antimony is as a new type of catalyst used in the production process of polyester (PET). In the process of polyester polycondensation reaction, it can activate the relevant functional groups of the reactants and promote the reaction. It is used for bottle-grade slices, textile slices and film-grade slices in polyester production. Ethylene glycol antimony has a low impurity content, is easily soluble in ethylene glycol, and is non-toxic. Its performance is better than antimony trioxide and antimony acetate.

[0003] In the production process of ethylene glycol antimony, the raw materials ethylene glycol and antimony trioxide react to generate a mixture of ethylene glycol antimony and water, and then the water in the mixture is evaporated through distillation to leave ethylene glycol antimony. During the distillation process, as the water evaporates, the concentration of the mixture increases, from dilute to viscous. When heated continuously, it may cause gelatinization of ethylene glycol antimony and generate other substances, affecting the purity of ethylene glycol antimony. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a device for distilling wastewater generated during the production of ethylene glycol antimony, comprising an anti-gelatinization mechanism, the anti-gelatinization mechanism also includes a distillation flask, a rotating rod is rotatably connected to the inner wall of the distillation flask, and a heating plate is fixedly connected to the bottom of the distillation flask; The anti-adhesion mechanism comprises a sliding ring slidably connected to the outer wall of the rotating rod, a connecting rod is rotatably connected to the inner wall of the sliding ring, and a shock-absorbing tooth is fixedly connected to the outer wall of the rotating rod; The material inlet and outlet mechanism comprises a material inlet fixedly connected to the top of the distillation flask, a fixed partition is fixedly connected to the inner wall of the distillation flask, and a spring 2 is fixedly connected to the top of the fixed partition.

[0005] Preferably, the anti-gelatinization mechanism also includes a floating block slidably connected to the outer wall of the rotating rod, a scraper 1 is fixedly connected to the outer wall of the floating block, a stirring rod is fixedly connected to the outer wall of the rotating rod, the bottom of the stirring rod is slidably connected to the inner wall of the distillation flask, and a fixed bracket 1 is fixedly connected to the top of the distillation flask. When the mixture of ethylene glycol antimony and water is continuously heated, the liquid level fluctuates up and down, driving the floating block to move up and down, and at the same time, the scraper 1 scrapes and cleans the inner wall of the distillation flask when it moves up and down. The stirring rod is used to stir the mixture of ethylene glycol antimony and water to keep it in a uniformly mixed state, which can also improve the efficiency of evaporation.

[0006] Preferably, the anti-gelatinization mechanism also includes a motor fixedly connected to the inner wall of the fixed bracket, a half tooth is fixedly connected to the bottom of the motor, a gear is meshedly connected to the outer wall of the half tooth, the bottom of the gear is fixedly connected to the top of the rotating rod, a hydrocondensate tube is fixedly connected to the outer wall of the distillation flask, and a floating block is provided by utilizing the characteristic that when the mixed liquid of ethylene glycol antimony and water is heated, the liquid surface will fluctuate, and when the mixed liquid of ethylene glycol antimony and water is continuously heated, the floating block floats on the liquid surface and moves up and down with the fluctuation of the liquid surface. When the floating block moves up and down, the inner wall of the distillation flask is continuously scraped by a scraper to prevent the liquid level from dropping after the water in the mixed liquid is evaporated, and some water droplets of the mixed liquid remain on the inner wall of the distillation flask. When the heating is continued, the water in the water droplets of the mixed liquid is evaporated, and the remaining ethylene glycol antimony remains on the inner wall of the distillation flask. Since the distillation flask is Metal material has high thermal conductivity, which may cause ethylene glycol antimony to gelatinize when heated continuously. At the same time, the motor runs and drives the half-tooth to rotate. Since the half-tooth has only some convex teeth, when it rotates, it drives the gear to rotate when it is meshed with the gear. When it is slidably connected with the gear, the gear stops rotating, forming an indirect rotation. When the gear rotates intermittently, the rotating rod drives the stirring rod to rotate together to stir the mixed liquid on the bottom of the distillation flask to make it evenly mixed and reduce long-term contact with the bottom to prevent the evaporation of water during the distillation process. The concentration of the mixed liquid becomes higher and becomes viscous and adheres to the bottom of the distillation flask. When heated continuously, the thick mixed liquid will gelatinize, and then generate other substances, affecting the purity of ethylene glycol antimony. It will also make it difficult to clean the inner wall of the distillation flask, increasing the subsequent cost of cleaning and maintenance of the distillation flask.

[0007] Preferably, the anti-gelatinization mechanism also includes a second fixed bracket fixedly connected to the outer wall of the hydrocondensate tube, a connecting pipe is fixedly connected to the outer wall of the hydrocondensate tube, and a collecting box 1 is fixedly connected to the outer wall of the connecting pipe. The high-temperature water vapor inside the hydrocondensate tube liquefies when it contacts the water-cooled inner wall of the hydrocondensate tube, and becomes small water droplets, which then gather and flow downward, pass through the connecting pipe, and finally flow into the collecting box 1, thereby preventing the leakage of waste gas and waste water from affecting the air and the environment. The second fixed bracket is used to fix the hydrocondensate tube to prevent it from tilting or shaking, thereby affecting the liquefaction of water vapor.

[0008] Preferably, the anti-adhesion mechanism also includes a scraper 2 slidably connected to the outer wall of the stirring rod, the inner wall of the scraper 2 is rotatably connected to the outer wall of the connecting rod, the outer wall of the scraper 2 is fixedly connected with a sliding block, the outer wall of the stirring rod is provided with a sliding groove, the outer wall of the sliding block is meshingly connected with the inner wall of the stirring rod, and utilizing the characteristic of the scraper 2 moving outward to provide a sliding ring, and the three scrapers 2 are connected to the sliding ring through three connecting rods, and when the scraper 2 moves back and forth, the sliding ring is synchronously driven to move up and down, so that when the sliding ring moves up and down, the synchronous movement distance of the scraper 2 can be controlled, so as to avoid a stirring rod being stuck by a large piece of ethylene glycol antimony crystal, because The rotation speed of the motor used for stirring will not be too fast, so that the centrifugal force generated by the rotating rod will not be particularly large, so that a single scraper 2 cannot scrape and clean the larger antimony glycol crystals on the stirring rod. The scraper 2 can be moved synchronously through the sliding ring. When a scraper 2 is blocked by large antimony glycol crystals and cannot move, but other scrapers 2 are not blocked and restricted by the large crystals, the movement of other scrapers 2 can drive the sliding ring to move up or down. When the sliding ring moves, it will push the blocked scraper 2 to move, thereby increasing its scraping force, so as to achieve the scraping and cleaning of the larger antimony glycol crystals and prevent it from affecting the normal rotation of the rotating rod and the stirring rod.

[0009] Preferably, the anti-adhesion mechanism also includes a spring 1 fixedly connected to the inner wall of the rotating rod, an end of the outer wall of the spring 1 away from the rotating rod is fixedly connected to the outer wall of the sliding block, a sliding partition is fixedly connected to the inner wall of the rotating rod, an end of the outer wall of the sliding partition away from the rotating rod is fixedly connected to the outer wall of the sliding block, and the outer wall of the sliding partition is slidably connected to the inner wall of the stirring rod. Utilizing the characteristic of the above-mentioned continuous indirect rotation of the rotating rod, a scraper 2 is provided. When the rotating rod rotates, the centrifugal force generated will push the scraper 2 to scrape along the outer surface of the stirring rod. When the rotating rod stops rotating, the scraper 2 is scraped and reset by the pulling force of the spring 1, so as to achieve indirect rotation of the rotating rod. During the rotation of the scraper, the stirring rod is scraped back and forth to clean it to prevent the ethylene glycol antimony crystals produced after the water in the mixed liquid evaporates from adhering to the stirring rod, affecting the rotation of the rotating rod and the stirring rod, increasing the burden on the motor, and affecting the normal stirring operation. At the same time, during the back and forth scraping of the scraper 2, the sliding block moves back and forth along the sliding groove to ensure that the scraper 2 will not be accidentally misplaced when moving, which will affect the cleaning of the stirring rod. When the scraper 2 moves back and forth, it drives the sliding partition to move together to prevent the ethylene glycol antimony crystals from entering the sliding groove when the stirring rod rotates, causing the spring 1 to be stuck and affecting the retraction of the scraper 2, thereby affecting the normal rotation of the rotating rod and the stirring rod.

[0010] Preferably, the feeding and discharging mechanism also includes a conical partition fixedly connected to the outer wall of the second spring away from one end of the fixed partition, the bottom of the heating plate is fixedly connected to the collecting box 2, the top of the collecting box 2 is fixedly connected to an electric telescopic rod, and the top of the electric telescopic rod is fixedly connected to a conical plate. The conical partition is used to isolate the water vapor inside the distillation flask from the outside world to avoid leakage of exhaust gas affecting the air and the environment. The collecting box 2 is used to collect ethylene glycol antimony produced after the evaporation of water in the mixed liquid. When the ethylene glycol antimony needs to be collected, the electric telescopic rod is used to control the passage between the distillation flask and the collecting box 2 to open and communicate with each other.

[0011] Preferably, the feeding and discharging mechanism also includes a piston column fixedly connected to the top of the conical plate, a connecting groove is provided at the bottom of the distillation flask, the outer wall of the piston column is slidably connected to the bottom of the distillation flask, a push plate is fixedly connected to the outer wall of the scraper 2, and the bottom of the push plate is slidably connected to the inner wall of the distillation flask. By utilizing the rotation characteristics of the above-mentioned stirring rod, after the water in the mixed liquid of ethylene glycol antimony and water is evaporated and ethylene glycol antimony crystals are generated, the heating plate stops heating, and the electric telescopic rod moves downward, driving the conical plate and the piston column to move downward together, so that the connecting groove is opened. At this time, the interior of the distillation flask is interconnected with the second collecting box. Through the rotation of the stirring rod, the ethylene glycol antimony crystals will be on one side of the stirring rod. When the stirring rod stops rotating, the scraper 2 drives the push plate to retract. , so that the ethylene glycol antimony crystals on one side of the stirring rod are pushed to the connecting groove position, fall downward, slide downward through the upper surface of the conical plate, and finally slide into the second collecting box, thereby realizing the automatic recovery of ethylene glycol antimony, improving the recovery efficiency, and reducing labor costs. At the same time, the feed pipe is connected to the feed port, and the mixed liquid of ethylene glycol antimony and water in the feed pipe pushes the conical partition when moving, so that the mixed liquid passes through the surface of the conical partition through the fixed partition to reach the inside of the distillation flask, which is convenient for feeding. When the mixed liquid inside the distillation flask is filled and the mixed liquid in the feed pipe no longer moves, the conical partition is pushed by the second spring to block the feed port again, so as to prevent the exhaust gas from being discharged from the feed port when the mixed liquid evaporates, thereby causing pollution to the air and the environment.

[0012] A method for using a device for distilling wastewater generated during the production of ethylene glycol antimony comprises the following steps: S1: Before using the device, install the device at the required position, connect the feed port to the feed pipe, turn on the power of the motor and the electric telescopic rod, and set a floating block. When the mixture of ethylene glycol antimony and water is continuously heated, the floating block floats on the liquid surface and moves up and down with the fluctuation of the liquid surface; S2: When the floating block moves up and down, the scraper 1 continuously scrapes the inner wall of the distillation flask to prevent the water in the mixed liquid from evaporating and the liquid level from dropping. Some water droplets of the mixed liquid remain on the inner wall of the distillation flask. When the heating is continued, the water in the water droplets of the mixed liquid is evaporated and the remaining antimony glycol remains on the inner wall of the distillation flask. S3: Since the distillation flask is made of metal with high thermal conductivity, continuous heating may cause the antimony glycol to gelatinize and generate other substances, which will affect the purity of the antimony glycol. It will also make it difficult to clean the inner wall of the distillation flask, increasing the subsequent cleaning and maintenance costs of the distillation flask.

[0013] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that when the mixed liquid of ethylene glycol antimony and water is heated, the liquid surface will fluctuate. A floating block is provided. When the mixed liquid of ethylene glycol antimony and water is continuously heated, the floating block floats on the liquid surface and moves up and down with the fluctuation of the liquid surface. When the floating block moves up and down, a scraper is used to continuously scrape the inner wall of the distillation flask to prevent the liquid surface from dropping after the water in the mixed liquid is evaporated. Some water droplets of the mixed liquid remain on the inner wall of the distillation flask. When the heating is continued, the water in the water droplets of the mixed liquid is evaporated, and the remaining ethylene glycol antimony remains on the inner wall of the distillation flask. Since the distillation flask is made of metal with high thermal conductivity, the ethylene glycol may be evaporated when the heating is continued. Antimony is gelatinized. At the same time, the motor runs and drives the half-tooth to rotate. Since the half-tooth has only some convex teeth, when it rotates, it drives the gear to rotate when it is meshed with the gear. When it is slidingly connected with the gear, the gear stops rotating, forming an intermittent rotation. When the gear rotates intermittently, the stirring rod is driven to rotate together through the rotating rod to stir the mixed liquid on the bottom of the distillation flask to make it evenly mixed and reduce long-term contact with the bottom to prevent the evaporation of water during the distillation process. The concentration of the mixed liquid becomes higher and becomes viscous and adheres to the bottom of the distillation flask. When heated continuously, the thick mixed liquid gelatinizes, and then generates other substances, affecting the purity of ethylene glycol antimony.

[0014] (2) The present invention utilizes the characteristic of the above-mentioned rotating rod that it rotates indirectly and continuously, and sets a scraper 2. When the rotating rod rotates, the centrifugal force generated will push the scraper 2 to scrape along the outer surface of the stirring rod. When the rotating rod stops rotating, the scraper 2 is pulled by the spring 1 to scrape and reset, so as to achieve the back and forth scraping and cleaning of the stirring rod when the rotating rod rotates indirectly, so as to prevent the ethylene glycol antimony crystals generated after the water in the mixed liquid evaporates from adhering to the stirring rod, affecting the rotation of the rotating rod and the stirring rod, increasing the burden of the motor, and affecting the normal stirring operation. At the same time, during the back and forth scraping of the scraper 2, the sliding block moves back and forth along the sliding groove, so as to ensure that the scraper 2 will not be misaligned when moving, thereby affecting the cleaning of the stirring rod. When the scraper 2 moves back and forth, it drives the sliding partition to move together, so as to prevent the ethylene glycol antimony crystals from entering the sliding groove when the stirring rod rotates, causing the spring 1 to be stuck and affecting the retraction of the scraper 2, thereby affecting the normal rotation of the rotating rod and the stirring rod.

[0015] (3) The present invention utilizes the characteristic that the scraper 2 moves outward and sets a sliding ring. The three scrapers 2 are connected to the sliding ring through three connecting rods. When the scraper 2 moves back and forth, it synchronously drives the sliding ring to move up and down. When the sliding ring moves up and down, the distance of the synchronous movement of the scraper 2 can be controlled, so as to avoid that when a certain stirring rod is stuck by a large piece of ethylene glycol antimony crystal, because the rotation speed of the motor used for stirring will not be too fast, the centrifugal force generated by the rotating rod will not be particularly large, so that a single scraper 2 cannot scrape and clean the large ethylene glycol antimony crystal on the stirring rod. The scraper 2 can be moved synchronously through the sliding ring. When a certain scraper 2 is blocked by a large piece of ethylene glycol antimony crystal and cannot move, but other scrapers 2 are not blocked and restricted by the large crystal, the movement of other scrapers 2 can drive the sliding ring to move up or down. When the sliding ring moves, it will push the blocked scraper 2 to move, thereby increasing its scraping force, so as to achieve the scraping and cleaning of the large ethylene glycol antimony crystal, and prevent the normal rotation of the rotating rod and the stirring rod from being affected.

[0016] (4) The present invention utilizes the characteristic of the above-mentioned stirring rod rotating. After the water in the mixture of ethylene glycol antimony and water is evaporated and ethylene glycol antimony crystals are generated, the heating plate stops heating, the electric telescopic rod moves downward, driving the conical plate and the piston rod to move downward together, so that the connecting groove is opened. At this time, the interior of the distillation flask and the second collecting box are interconnected. Through the rotation of the stirring rod, the ethylene glycol antimony crystals are placed on one side of the stirring rod. When the stirring rod stops rotating, the second scraper drives the push plate to retract, so that the ethylene glycol antimony crystals on one side of the stirring rod are pushed to the connecting groove position, fall downward, and slide downward through the upper surface of the conical plate. , and finally slides into the second collecting box, realizing the automatic recovery of ethylene glycol antimony, improving the recovery efficiency, reducing labor costs, and connecting the feed pipe with the feed port. When the mixed liquid of ethylene glycol antimony and water in the feed pipe moves, it pushes the conical partition plate, so that the mixed liquid passes through the surface of the conical partition plate through the fixed partition plate to reach the inside of the distillation flask, which is convenient for feeding. When the mixed liquid inside the distillation flask is filled and the mixed liquid in the feed pipe no longer moves, the conical partition plate is pushed by the second spring to block the feed port again, so as to prevent the exhaust gas from being discharged from the feed port when the mixed liquid evaporates, causing pollution to the air and the environment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1 - Figure 4The present invention is a device for distilling wastewater generated during the production of ethylene glycol antimony, comprising an anti-gelatinization mechanism 1, wherein the anti-gelatinization mechanism 1 further comprises a distillation flask 101, a rotating rod 102 is rotatably connected to the inner wall of the distillation flask 101, and a heating plate 103 is fixedly connected to the bottom of the distillation flask 101; The anti-adhesion mechanism 2 includes a sliding ring 201 slidably connected to the outer wall of the rotating rod 102, a connecting rod 202 is rotatably connected to the inner wall of the sliding ring 201, and a shock-absorbing tooth 203 is fixedly connected to the outer wall of the rotating rod 102; The material inlet and outlet mechanism 3 includes a material inlet 301 fixedly connected to the top of the distillation flask 101, a fixed partition 302 is fixedly connected to the inner wall of the distillation flask 101, and a spring 2 303 is fixedly connected to the top of the fixed partition 302.

[0022] The anti-gelatinization mechanism 1 also includes a floating block 104 slidably connected to the outer wall of the rotating rod 102, a scraper 105 is fixedly connected to the outer wall of the floating block 104, a stirring rod 106 is fixedly connected to the outer wall of the rotating rod 102, the bottom of the stirring rod 106 is slidably connected to the inner wall of the distillation flask 101, and a fixed bracket 107 is fixedly connected to the top of the distillation flask 101. When the mixture of ethylene glycol antimony and water is continuously heated, the liquid level fluctuates up and down, driving the floating block 104 to move up and down, and at the same time, the scraper 105 scrapes and cleans the inner wall of the distillation flask 101 when it moves up and down. The stirring rod 106 is used to stir the mixture of ethylene glycol antimony and water to keep it in a uniformly mixed state, and can also improve the efficiency of evaporation.

[0023] The anti-gelling mechanism 1 also includes a motor 108 fixedly connected to the inner wall of the fixed bracket 107, a half tooth 109 fixedly connected to the bottom of the motor 108, a gear 110 meshingly connected to the outer wall of the half tooth 109, the bottom of the gear 110 is fixedly connected to the top of the rotating rod 102, and a hydrocondensate tube 111 is fixedly connected to the outer wall of the distillation flask 101. When the mixed liquid of ethylene glycol antimony and water is heated, the liquid surface will fluctuate, and a floating block 104 is set to prevent the ethylene glycol from being swayed. When the mixed liquid of antimony and water is continuously heated, the liquid surface on which the floating block 104 floats moves up and down with the fluctuation of the liquid surface. When the floating block 104 moves up and down, the scraper 105 continuously scrapes the inner wall of the distillation flask 101 to prevent the water in the mixed liquid from evaporating and the liquid surface from dropping. Some water droplets of the mixed liquid remain on the inner wall of the distillation flask 101. When the heating is continuously continued, the water in the water droplets of the mixed liquid is evaporated, and the remaining ethylene glycol antimony remains on the inner wall of the distillation flask 101. The distillation flask 101 is made of metal with high thermal conductivity. When heated continuously, the antimony glycol may be gelatinized. At the same time, the motor 108 runs and drives the half-tooth 109 to rotate. Since the half-tooth has only some convex teeth, when it rotates, it meshes with the gear 110 and drives the gear 110 to rotate. When it is slidably connected with the gear 110, the gear 110 stops rotating, forming an indirect rotation. When the gear 110 rotates intermittently, the stirring rod 106 is driven to rotate together through the rotating rod 102 to stir the mixed liquid on the bottom surface of the distillation flask 101 to mix it evenly and reduce long-term contact with the bottom to prevent the evaporation of water during the distillation process from increasing the concentration of the mixed liquid, making it viscous and adhering to the bottom surface of the distillation flask 101. When heated continuously, the thick mixed liquid will gelatinize and generate other substances, affecting the purity of the antimony glycol. It will also cause the problem of difficulty in cleaning the inner wall of the distillation flask 101, increasing the cost of subsequent cleaning and maintenance of the distillation flask 101.

[0024] The anti-gelatinization mechanism 1 also includes a second fixed bracket 112 fixedly connected to the outer wall of the hydrocondenser tube 111, a connecting pipe 113 is fixedly connected to the outer wall of the hydrocondenser tube 111, and a collecting box 114 is fixedly connected to the outer wall of the connecting pipe 113. The high-temperature water vapor inside the hydrocondenser tube 111 liquefies when it contacts the water-cooled inner wall of the hydrocondenser tube 111, and becomes small water droplets, which then gather and flow downward, pass through the connecting pipe 113, and finally flow into the collecting box 114 to prevent the leakage of waste gas and waste water from affecting the air and environment. The second fixed bracket 112 is used to fix the hydrocondenser tube 111 to prevent it from tilting or shaking, thereby affecting the liquefaction of water vapor.

[0025] For example 2, please refer to Figure 5 - Fig.10The present invention is a device for producing wastewater during the distillation of ethylene glycol antimony. On the basis of the first embodiment, the anti-adhesion mechanism 2 also includes a scraper 204 slidably connected to the outer wall of the stirring rod 106. The inner wall of the scraper 204 is rotatably connected to the outer wall of the connecting rod 202. A sliding block 205 is fixedly connected to the outer wall of the scraper 204. A sliding groove 206 is provided on the outer wall of the stirring rod 106. The outer wall of the sliding block 205 is meshed and connected with the inner wall of the stirring rod 106. By utilizing the characteristic that the scraper 204 moves outward, a sliding ring 201 is set. The three scrapers 204 are connected to the sliding ring 201 through three connecting rods 202. When the scraper 204 moves back and forth, the sliding ring 201 is synchronously driven to move up and down. When the sliding ring 201 moves up and down, the synchronous moving distance of the scraper 204 can be controlled to avoid a certain stirring rod. When 106 is stuck by large pieces of antimony glycol crystals, because the rotation speed of the motor 108 used for stirring will not be too fast, the centrifugal force generated by the rotating rod 102 will not be particularly large, so that a single scraper 204 cannot scrape and clean the larger antimony glycol crystals on the stirring rod 106, and the scraper 204 can be moved synchronously through the sliding ring 201. When a certain scraper 204 is blocked by the large pieces of antimony glycol crystals and cannot move, but other scrapers 204 are not blocked and restricted by the large crystals, the movement of other scrapers 204 can drive the sliding ring 201 to move up or down. When the sliding ring 201 moves, it will push the blocked scraper 204 to move, thereby increasing its scraping force, so as to scrape and clean the larger antimony glycol crystals and prevent affecting the normal rotation of the rotating rod 102 and the stirring rod 106.

[0026] The anti-adhesion mechanism 2 also includes a spring 207 fixedly connected to the inner wall of the rotating rod 102, an end of the outer wall of the spring 207 away from the rotating rod 102 is fixedly connected to the outer wall of the sliding block 205, a sliding partition 208 is fixedly connected to the inner wall of the rotating rod 102, an end of the outer wall of the sliding partition 208 away from the rotating rod 102 is fixedly connected to the outer wall of the sliding block 205, and the outer wall of the sliding partition 208 is slidably connected to the inner wall of the stirring rod 106. Utilizing the characteristic of the above-mentioned continuous indirect rotation of the rotating rod 102, a scraper 204 is provided. When the rotating rod 102 rotates, the centrifugal force generated will push the scraper 204 to scrape along the outer surface of the stirring rod 106. When the rotating rod 102 stops rotating, the scraper 204 is scraped and reset by the pulling force of the spring 207, so as to achieve the rotation of the rotating rod 10 2 During indirect rotation, the stirring rod 106 is scraped back and forth to clean it to prevent the ethylene glycol antimony crystals produced after the water in the mixed liquid evaporates from adhering to the stirring rod 106, affecting the rotation of the rotating rod 102 and the stirring rod 106, increasing the burden of the motor 108, and affecting the normal stirring operation. At the same time, during the back and forth scraping of the scraper 204, the sliding block 205 moves back and forth along the sliding groove 206 to ensure that the scraper 204 will not be accidentally misplaced when moving, and the cleaning of the stirring rod 106 is affected. When the scraper 204 moves back and forth, it drives the sliding partition 208 to move together to prevent the ethylene glycol antimony crystals from entering the sliding groove 206 when the stirring rod 106 rotates, causing the spring 1 207 to be stuck and affecting the retraction of the scraper 204, thereby affecting the normal rotation of the rotating rod 102 and the stirring rod 106.

[0027] The feeding and discharging mechanism 3 also includes a conical partition 304 fixedly connected to the outer wall of the second spring 303 away from one end of the fixed partition 302. The bottom of the heating plate 103 is fixedly connected to the second collecting box 305, the top of the second collecting box 305 is fixedly connected to the electric telescopic rod 306, and the top of the electric telescopic rod 306 is fixedly connected to the conical plate 307. The conical partition 304 is used to isolate the water vapor inside the distillation flask 101 from the outside world to avoid leakage of exhaust gas and affect the air and environment. The second collecting box 305 is used to collect ethylene glycol antimony produced after the evaporation of water in the mixed liquid. When the ethylene glycol antimony needs to be collected, the electric telescopic rod 306 is used to control the opening of the channel between the distillation flask 101 and the second collecting box 305 to make them communicate with each other.

[0028] The feeding and discharging mechanism 3 also includes a piston column 308 fixedly connected to the top of the conical plate 307, a connecting groove 309 is provided at the bottom of the distillation flask 101, the outer wall of the piston column 308 is slidably connected to the bottom of the distillation flask 101, and a push plate 310 is fixedly connected to the outer wall of the scraper 204, and the bottom of the push plate 310 is slidably connected to the inner wall of the distillation flask 101. By utilizing the rotation characteristics of the above-mentioned stirring rod 106, after the water in the mixed liquid of ethylene glycol antimony and water is evaporated and ethylene glycol antimony crystals are generated, the heating plate 103 stops heating, and the electric telescopic rod 306 moves downward, driving the conical plate 307 and the piston column 308 to move downward together, so that the connecting groove 309 is opened. At this time, the interior of the distillation flask 101 is interconnected with the collecting box 2 305. Through the rotation of the stirring rod 106, the ethylene glycol antimony crystals are on one side of the stirring rod 106. When the stirring rod 106 stops rotating, the scraper 20 4 drives the push plate 310 to retract, so that the ethylene glycol antimony crystals on one side of the stirring rod 106 are pushed to the position of the connecting groove 309, fall downward, slide downward through the upper surface of the conical plate 307, and finally slide into the second collecting box 305, so as to realize the automatic recovery of ethylene glycol antimony, improve the recovery work efficiency, and reduce labor costs. At the same time, the feed pipe is connected with the feed port 301. When the mixed liquid of ethylene glycol antimony and water in the feed pipe moves, it pushes the conical partition 304, so that the mixed liquid passes through the surface of the conical partition 304 through the fixed partition 302 to reach the inside of the distillation flask 101, which is convenient for feeding. When the mixed liquid inside the distillation flask 101 is filled and the mixed liquid in the feed pipe no longer moves, the conical partition 304 is pushed by the second spring 303 to block the feed port 301 again, so as to prevent the waste gas from being discharged from the feed port 301 when the mixed liquid evaporates, causing pollution to the air and the environment.

[0029] The method for using the device for distilling ethylene glycol antimony comprises the following steps: S1: Before using the device, first install the device at the required position, then connect the feed port 301 to the feed pipe, and turn on the power of the motor 108 and the electric telescopic rod 306, and set a floating block 104. When the mixed liquid of ethylene glycol antimony and water is continuously heated, the floating block 104 floats on the liquid surface and moves up and down with the fluctuation of the liquid surface; S2: When the floating block 104 moves up and down, the scraper 105 continuously scrapes the inner wall of the distillation flask 101 to prevent the water in the mixed liquid from evaporating and the liquid level from dropping. Some water droplets of the mixed liquid remain on the inner wall of the distillation flask 101. When the heating is continued, the water in the water droplets of the mixed liquid is evaporated and the remaining antimony glycol remains on the inner wall of the distillation flask 101. S3: Since the distillation flask 101 is made of metal and has high thermal conductivity, continuous heating may cause the antimony glycol to gelatinize and generate other substances, which will affect the purity of the antimony glycol. It will also make it difficult to clean the inner wall of the distillation flask 101, increasing the cost of subsequent cleaning and maintenance of the distillation flask 101.

[0030] A specific application of this embodiment is: before using the device, first install the device at a desired position, then connect the feed port 301 to the feed pipe, turn on the power of the motor 108 and the electric telescopic rod 306, and set a floating block 104. When the mixed liquid of ethylene glycol antimony and water is continuously heated, the floating block 104 floats on the liquid surface and moves up and down with the fluctuation of the liquid surface. When the floating block 104 moves up and down, the inner wall of the distillation flask 101 is continuously scraped by the scraper 105 to prevent the liquid surface from dropping after the water in the mixed liquid is evaporated, and some water droplets of the mixed liquid remain on the inner wall of the distillation flask 101. When heating is continued, the water in the mixed liquid water droplets is evaporated, and the remaining ethylene glycol antimony remains on the inner wall of the distillation flask 101. Since the distillation flask 101 is made of metal with high thermal conductivity, the ethylene glycol antimony may be gelatinized when heated continuously. At the same time, the motor 108 runs and drives the half-tooth 109 to rotate. Since the half-tooth has only some convex teeth, when it rotates, it meshes with the gear 110 to drive the gear 110 to rotate. When it is slidingly connected with the gear 110, the gear 110 stops rotating, forming an indirect rotation. When the gear 110 rotates intermittently, the rotating rod 102 drives the stirring rod 106 to rotate together to stir the mixed liquid on the bottom surface of the distillation flask 101 to make it evenly mixed and reduce long-term contact with the bottom to prevent the mixed liquid from becoming more concentrated and viscous and adhering to the bottom surface of the distillation flask 101 due to the evaporation of water during the distillation process. When heated continuously, the thick mixed liquid will gelatinize and generate other substances, affecting the purity of ethylene glycol antimony. It will also cause the problem of difficulty in cleaning the inner wall of the distillation flask 101, increasing the subsequent cleaning and maintenance costs of the distillation flask 101.

[0031] Taking advantage of the above-mentioned feature that the rotating rod 102 rotates indirectly, a second scraper 204 is provided. When the rotating rod 102 rotates, the centrifugal force generated will push the second scraper 204 to scrape along the outer surface of the stirring rod 106. When the rotating rod 102 stops rotating, the second scraper 204 is pulled by the spring 1 207 to scrape and reset, so as to achieve back and forth scraping and cleaning of the stirring rod 106 when the rotating rod 102 rotates indirectly, so as to prevent the ethylene glycol antimony crystals generated after the water in the mixed liquid evaporates from adhering to the stirring rod 106, affecting the rotation of the rotating rod 102 and the stirring rod 106, and increasing The burden of the motor 108 affects the normal stirring operation. At the same time, during the scraper 204 scraping back and forth, the sliding block 205 moves back and forth along the sliding groove 206 to ensure that the scraper 204 will not be misplaced when moving, and the cleaning of the stirring rod 106 is affected. When the scraper 204 moves back and forth, it drives the sliding partition 208 to move together to prevent the ethylene glycol antimony crystals from entering the sliding groove 206 when the stirring rod 106 rotates, so that the spring 1 207 is stuck and affects the retraction of the scraper 204, thereby affecting the normal rotation of the rotating rod 102 and the stirring rod 106. A sliding ring 201 is used to connect three scrapers 204 to the sliding ring 201 through three connecting rods 202. When the scrapers 204 move back and forth, the sliding ring 201 is synchronously driven to move up and down. When the sliding ring 201 moves up and down, the distance of synchronous movement of the scrapers 204 can be controlled to avoid a certain stirring rod 106 being stuck by a large piece of ethylene glycol antimony crystal. Because the rotation speed of the motor 108 used for stirring is not too fast, the centrifugal force generated by the rotating rod 102 is not particularly large, so that a single scraper 204 cannot be used to move the large ethylene glycol antimony crystal on the stirring rod 106. The crystals are scraped and cleaned, and the scraper 204 can be moved synchronously by the sliding ring 201. When a certain scraper 204 is blocked by the large crystals of ethylene glycol antimony and cannot move, but other scrapers 204 are not blocked and restricted by the large crystals, the movement of other scrapers 204 can drive the sliding ring 201 to move up or down. When the sliding ring 201 moves, it will push the blocked scraper 204 to move, thereby increasing its scraping force, so as to achieve scraping and cleaning of the larger ethylene glycol antimony crystals and prevent affecting the normal rotation of the rotating rod 102 and the stirring rod 106.

[0032] By utilizing the rotating characteristics of the stirring rod 106, after the water in the mixture of ethylene glycol antimony and water is evaporated and ethylene glycol antimony crystals are generated, the heating plate 103 stops heating, and the electric telescopic rod 306 moves downward, driving the conical plate 307 and the piston rod 308 to move downward together, so that the connecting groove 309 is opened. At this time, the interior of the distillation flask 101 and the collecting box 2 305 are interconnected. Through the rotation of the stirring rod 106, the ethylene glycol antimony crystals are on one side of the stirring rod 106. When the stirring rod 106 stops rotating, the scraper 204 drives the push plate 310 to retract, so that the ethylene glycol antimony crystals on one side of the stirring rod 106 are pushed to the connecting groove 309 position, fall downward, and pass through the upper surface of the conical plate 307. It slides downward and finally slides into the collecting box 2 305, realizing the automatic recovery of ethylene glycol antimony, improving the recovery efficiency and reducing the labor cost. At the same time, the feeding pipe is connected with the feeding port 301. The mixed liquid of ethylene glycol antimony and water in the feeding pipe pushes the conical partition 304 when moving, so that the mixed liquid passes through the surface of the conical partition 304 through the fixed partition 302 to reach the inside of the distillation flask 101, which is convenient for feeding. When the mixed liquid inside the distillation flask 101 is filled and the mixed liquid in the feeding pipe no longer moves, the conical partition 304 is pushed by the spring 2 303 to block the feeding port 301 again, so as to prevent the exhaust gas from being discharged from the feeding port 301 when the mixed liquid evaporates, causing pollution to the air and the environment.
