Description

Technical Field

[0001] The invention relates to the technical field of reaction kettles, and more specifically to a thiourea purification and treatment device. Background Art

[0002] Thiourea is an organic sulfur-containing compound, white and shiny crystals, mainly used as raw materials for manufacturing drugs, dyes, resins, compression molding powders, etc. It is also used as a vulcanization accelerator for rubber, a flotation agent for metal minerals, etc. It is formed by the reaction of hydrogen sulfide with lime slurry to form calcium hydrosulfide, which is then reacted with calcium cyanamide.

[0003] After the preparation of industrial thiourea, there may be a large amount of calcium ions and other impurity ions remaining in it, and the crystal particles are unevenly distributed, easy to break, and have a low bulk density, which affects storage and transportation. Therefore, it is necessary to add a solvent to the reactor again to dissolve the industrial thiourea in the solvent, and then add a precipitant to precipitate, and then collect the filtrate and filter and crystallize it again to complete the purification.

[0004] When using a reactor for heating and dissolving, the outer wall of the reactor is generally heated, and the inside of the reactor is heated by heat conduction. Since industrial thiourea is an irregular white crystal, it is precipitated at the bottom when heated in the solvent added to the reactor. Stirring is performed during the heating process to melt the industrial thiourea crystals. When stirring inside the reactor, the faster the better, and the melting speed and reaction speed need to be controlled. When the solvent in the reactor gradually approaches the maximum amount of dissolved industrial thiourea and the stirring speed is slow, thiourea crystals will precipitate at the bottom.

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] like Figure 1 to Figure 2 As shown, a thiourea purification treatment device according to an embodiment of the present invention comprises a kettle body 1, a support block 11 is fixedly installed on the lower outer wall of the kettle body 1, a first opening 12 is provided on the side wall of the kettle body 1, a top support frame 13 is fixedly installed on the upper outer wall of the kettle body 1, and a stirring device 2 is rotatably installed in the center of the top support frame 13;

[0032] like Figure 3 to Figure 4 As shown, the stirring device 2 includes a stirring rod 21 rotatably installed inside the kettle body 1, a stirring member 22 is slidably installed on the outer wall of the stirring rod 21, a telescopic power member 23 is rotatably installed inside the stirring rod 21, a scraping member 26 is fixedly installed at the bottom end of the telescopic power member 23, and a conveying reel 27 is fixedly installed at the lower part of the telescopic power member 23. The rotation of the stirring rod 21 drives the stirring member 22 to rotate to stir the thiourea liquid, the lifting of the stirring member 22 drives the scraping member 26 to contact the bottom center of the kettle body 1, the rotation of the stirring member 22 drives the scraping member 26 to peel off the thiourea crystals gathered in the bottom center of the kettle body 1, and the stirring member 22 drives the conveying reel 27 to rotate to transport the thiourea crystals.

[0033] It should be noted that, considering that when thiourea crystals are purified after preparation, the generally used method is to place industrial thiourea in a reactor for heating, stirring and melting. After complete melting, precipitation is carried out by adding a precipitant, and the precipitate and the solution are separated by filtering to complete the purification process. Since thiourea is a white crystal, it falls to the bottom of the reactor when entering the reactor. When the reactor is heated, it is heated by covering the outer wall of the reactor body 1. After the reactor is heated, the heat is conducted from the outer wall of the reactor body 1 to the solution inside the reactor body 1. Although the solution in the reactor is stirred during the melting process to accelerate the dissolution effect of thiourea and prevent thiourea from settling to the bottom, when the solution in the reactor tends to dissolve the maximum solubility of thiourea, the melting speed will slow down, thereby precipitating at the bottom. The thiourea precipitated at the bottom is melted due to heating, but due to the reduction of solubility in the reactor, the thiourea crystals that are not completely dissolved adhere to the inner wall of the bottom center of the reactor, resulting in a decrease in the dissolution effect of thiourea. In order to solve this problem, the following improvements have been made:

[0034] First, the first opening 12 at the lower part of the outer wall of the kettle body 1 is closed, and then the first opening 12 at the upper part of the kettle body 1 is opened, and the solvent is added into the kettle body 1 from the upper first opening 12, and then the thiourea crystals are added into the kettle body 1 from the upper first opening 12, and the outer wall of the kettle body 1 is heated, so that the solvent inside the kettle body 1 is heated. During the heating process, the stirring rod 21 is driven to rotate by a motor, and the rotation of the stirring rod 21 drives the stirring member 22 on the outer wall to rotate, and the stirring member 22 includes a stirring ring slidably mounted on the outer wall of the stirring rod 21. 221, a stirring blade 222 is fixedly installed on the outer wall of the stirring ring 221. When the stirring rod 21 drives the stirring ring 221 to rotate, the stirring blade 222 is also driven to rotate. The rotation of the stirring blade 222 can stir the solvent inside the kettle body 1. As the thiourea crystals inside the kettle body 1 dissolve, the solubility of thiourea in the solvent decreases. The stirring speed cannot be too fast. Therefore, the thiourea crystals precipitated at the bottom will be heated and stirred at the bottom of the kettle body 1, and will gather toward the bottom center of the kettle body 1 and adhere to the center bottom of the kettle body 1, causing In order to prevent the mixing from being insufficient, the telescopic power member 23 is opened to fully extend the telescopic power member 23, and then the telescopic power member 23 is driven to rotate by the motor, so that the scraper 26 at the bottom of the telescopic power member 23 can be driven to unfold and rotate with the telescopic power member 23. The scraper 26 contacts the bottom center of the kettle body 1, and the scraper 26 can scrape the thiourea crystals adhered to the bottom center of the kettle body 1 during the rotation process to prevent adhesion, and the conveying reel 27 on the lower outer wall of the telescopic power member 23 rotates synchronously, so that the scraper 26 scrapes the thiourea crystals adhered to the bottom center of the kettle body 1. The thiourea crystals are transported to the upper end of the stirring rod 21 through the stirring rod 21, and an upper transport port 211 is provided on the upper part of the stirring rod 21, so that the thiourea crystals can flow out from the upper transport port 211 and enter the interior of the kettle body 1 for stirring again, thereby accelerating the dissolution rate of the thiourea until the thiourea is completely dissolved, and then the precipitant is added to the interior of the kettle body 1 from the first opening 12 on the upper part of the outer wall of the kettle body 1 until the precipitation is completed, and the liquid is discharged from the first opening 12 at the lower part of the kettle body 1, and then filtered and crystallized, thereby completing the purification of the thiourea.

[0035] like Figures 4 to 7As shown, the stirring member 22 includes a stirring ring 221 slidably mounted on the outer wall of the stirring rod 21, and a stirring blade 222 is fixedly mounted on the outer wall of the stirring ring 221. The stirring blade 222 is arranged in a circular array with the stirring ring 221 as the center, and a stirring connecting block 224 is fixedly mounted at the center of the inner wall of the stirring ring 221. The outer wall of the stirring rod 21 is provided with a first slide groove 212, and the stirring connecting block 224 slides on the inner wall of the first slide groove 212. A power connecting ring 225 is fixedly mounted on the end of the stirring connecting block 224, and the power connecting ring 225 is rotatably mounted on the outer wall of the scraper 26. The rotation of the stirring rod 21 is used to drive the stirring ring 221 to rotate for stirring, and the lifting of the scraper 26 is used to drive the stirring ring 221 to lift and lower to adjust the position of the stirring ring 221 on the outer wall of the stirring rod 21.

[0036] It should be noted that, considering that the stirring position of the stirring member 22 is different, the stirring effect is different. When the stirring member 22 is located at the lower center of the kettle body 1, the thiourea will be in the middle and lower part of the liquid in the kettle body 1 during the stirring process, and the upper liquid will be less exposed to the thiourea component, but there will be no precipitation and aggregation at the bottom. If the stirring member 22 is located at the center of the kettle body 1, the thiourea crystals are mixed more evenly in the solution inside the kettle body 1, but when the solution inside the kettle body 1 tends to be saturated, precipitation is likely to occur. Therefore, a stirring connecting block 224 is slidably provided inside the stirring rod 21, and one end of the stirring connecting block 224 is connected to the stirring rod 21. Ring 221, the other end of the stirring connecting block 224 is connected with a power connecting ring 225. When the stirring rod 21 drives the stirring connecting block 224 to rotate, the stirring ring 221 and the stirring blade 222 can be driven to rotate, thereby realizing the stirring effect. A first slide groove 212 is provided on the stirring rod 21, and the stirring connecting block 224 slides on the inner wall of the first slide groove 212. The interior of the power connecting ring 225 is rotatably connected to the lower part of the scraper 26. When the telescopic power member 23 descends, the stirring member 22 can follow the telescopic power member 23 to descend, thereby preventing thiourea precipitation from continuing to be generated when the scraper 26 cleans the bottom end of the inner wall of the kettle body 1, thereby improving the dissolution effect.

[0037] like Figure 7 As shown, the stirring member 22 includes an isolating ring 223 fixedly mounted on the top of the stirring connecting block 224 , the outer diameter of the isolating ring 223 is the same as the inner diameter of the stirring rod 21 , and the height of the isolating ring 223 is the same as the height of the first slide groove 212 .

[0038] It should be noted that, considering that no thiourea crystals will be stuck inside the first slide groove 212 when the stirring member 22 is in normal use, an isolation ring 223 is provided at the top of the stirring connection block 224. When the scraper 26 engages with the inner wall of the stirring rod 21, no liquid will enter the inside of the stirring rod 21. When the telescopic power member 23 drives the scraper 26 to descend, the isolation ring 223 and the stirring ring 221 can isolate the thiourea crystals outside the first slide groove 212, thereby ensuring that the stirring connection block 224 slides inside the first slide groove 212.

[0039] like Figures 4 to 6 As shown, the telescopic power member 23 includes an upper transmission column 231 rotatably mounted inside the stirring rod 21, a lower connecting column 232 is slidably mounted on the bottom end of the upper transmission column 231, and the power connecting ring 225 is rotatably mounted on the outer wall of the lower connecting column 232.

[0040] It should be noted that, considering that the telescopic power member 23 can be adjusted to be telescopic when rotating, an upper transmission column 231 is rotatably installed inside the stirring rod 21, and a lower connecting column 232 is slidably installed at the bottom end of the upper transmission column 231. The rotation of the upper transmission column 231 can drive the lower connecting column 232 to rotate synchronously, so that the telescopic power member 23 has the functions of rotation and extension, driving the scraper 26 to seal the inside of the stirring rod 21 and scrape off the thiourea crystals adhered to the bottom of the kettle body 1.

[0041] like Figures 4 to 6 As shown, a first gear 24 is fixedly installed on the top of the stirring rod 21, and a second gear 25 is fixedly installed on the top of the telescopic power member 23. The outer walls of the first gear 24 and the second gear 25 are meshed with a transmission device 3, and the transmission device 3 is used to drive the stirring rod 21 to rotate and drive the lower connecting column 232 to rise and fall.

[0042] It should be noted that when it is necessary to drive the stirring rod 21 to rotate, the transmission device 3 is meshed with the first gear 24, which can drive the stirring rod 21 to rotate, thereby driving the stirring member 22 to rotate to stir the thiourea solution inside the kettle body 1, and the telescopic power member 23 is started to extend to drive the scraper 26 to descend, and then the transmission device 3 is raised and lowered to engage with the second gear 25, thereby driving the telescopic power member 23 and the scraper 26 to rotate, and the thiourea crystals adhered to the bottom center of the kettle body 1 are scraped off.

[0043] like Figures 5 to 7As shown, an extrusion cone block 28 and a transport reel 27 are fixedly mounted on the lower outer wall of the upper transmission column 231. The extrusion cone block 28 is at the same height as the isolation ring 223. The transport reel 27 is located directly below the extrusion cone block 28. The transport reel 27 is used to transport thiourea crystals. The extrusion cone block 28 is used to crush thiourea crystals. An upper transport port 211 is provided on the upper outer wall of the stirring rod 21. The thiourea crystals transported by the transport reel 27 flow out from the upper transport port 211.

[0044] It should be noted that when the thiourea crystals are scraped off from the bottom center of the kettle body 1, the thiourea crystals may be more aggregated than before, thus appearing in lumps. In order to facilitate the crushing of the thiourea crystals and their complete mixing in the solution inside the kettle body 1, a transport reel 27 is provided at the lower part of the lower connecting column 232. The transport reel 27 can rotate to transport the scraped thiourea crystals, and an extrusion cone block 28 is provided at the position of the isolation ring 223. When the transported thiourea crystals pass through the inside of the stirring rod 21, they can be crushed by the rotation of the extrusion cone block 28 and the extrusion of the inner wall of the isolation ring 223, thereby facilitating their dissolution inside the kettle body 1.

[0045] like Figure 6 to Figure 7 As shown, a plurality of bottom limit blocks 213 are fixedly mounted on the inner wall of the bottom end of the stirring rod 21, and the scraper 26 includes a square mounting block 261 fixedly mounted on the bottom center of the upper transmission column 231, and a fan-shaped scraper block 262 is rotatably mounted on the outer wall of the square mounting block 261. When the plurality of fan-shaped scraper blocks 262 are in the same plane, they form a sealed circular plate, and a torsion spring is provided at the connection position between the fan-shaped scraper block 262 and the square mounting block 261.

[0046] It should be noted that the bottom limit block 213 can make the multiple square mounting blocks 261 tend to be horizontal during the rotation process, and a torsion spring is provided at the connection position between the square mounting block 261 and the fan-shaped scraper block 262, so that when the fan-shaped scraper block 262 contacts the center of the bottom end of the inner wall of the kettle body 1, the center of the bottom end of the inner wall of the kettle body 1 can be scraped, and when the multiple fan-shaped scraper blocks 262 are in the same horizontal plane, the fan-shaped scraper block 262 is a whole, which can seal the inside of the stirring rod 21.

[0047] like Figures 4 to 5As shown, the transmission device 3 includes a first transmission rod 31 rotatably mounted on the top of the top support frame 13, a third gear 32 is fixedly mounted on the lower part of the first transmission rod 31, a fourth gear 33 is slidably mounted on the upper outer wall of the first transmission rod 31, a top slider 34 is rotatably mounted on the top outer wall of the first transmission rod 31, the first transmission rod 31 is meshed with the first gear 24, the top of the fourth gear 33 is rotatably connected to the bottom of the top slider 34, the top slider 34 is lifted and lowered to drive the fourth gear 33 to mesh with the second gear 25, and an adjusting member 35 is threadedly mounted on the top slider 34, and the adjusting member 35 is used to adjust the height of the fourth gear 33 and the top slider 34.

[0048] It should be noted that when it is necessary to drive the stirring rod 21 to rotate, the output shaft of the motor is connected to the first transmission rod 31, and the first transmission rod 31 drives the third gear 32 and the fourth gear 33 to rotate, and the third gear 32 is in a meshing state with the first gear 24. Therefore, when the third gear 32 rotates, the first gear 24 and the stirring rod 21 can be driven to rotate. The rotation of the stirring rod 21 can drive the stirring member 22 to rotate, thereby achieving a stirring effect, and the starting adjustment member 35 drives the top slider 34 to descend, and the top slider 34 is rotatably connected to the fourth gear 33, thereby driving the fourth gear 33 to descend, and the fourth gear 33 descends and meshes with the second gear 25, and the gear radius of the fourth gear 33 is greater than the gear radius of the second gear 25, and the gear radius of the fourth gear 33 is greater than the gear radius of the third gear 32. Therefore, when the fourth gear 33 drives the second gear 25 to rotate, the rotation speed of the second gear 25 is faster than the rotation speed of the first gear 24, so that when the scraping member 26 drives the conveying reel 27 to rotate, the liquid after the thiourea fusion can be conveyed.

[0049] like Figure 4 As shown, the adjusting member 35 includes a first supporting column 351 fixedly mounted on the top of the top supporting frame 13, a threaded rod 352 is rotatably mounted on the top of the first supporting column 351, the outer wall of the threaded rod 352 is engaged with the inside of the top slider 34, a handle 354 is fixedly mounted on the top of the threaded rod 352, and a first spring 353 is provided on the outer wall of the threaded rod 352.

[0050] It should be noted that when it is necessary to adjust the meshing state of the fourth gear 33 and the second gear 25, the handle 354 can be rotated, and the handle 354 drives the threaded rod 352 to rotate, and the threaded rod 352 engages with the top slider 34, thereby driving the top slider 34 to rise and fall, thereby adjusting the meshing state of the fourth gear 33 and the second gear 25.

[0051] like Figures 4 to 5As shown, a lifting member 29 is rotatably installed on the top of the stirring ring 221, and the lifting member 29 includes a first lifting ring 291 rotatably installed on the top of the stirring ring 221, and a lifting column 292 is fixedly installed on the top of the first lifting ring 291. The lifting column 292 passes through the interior of the kettle body 1 and is fixedly installed on the side wall of the first gear 24.

[0052] It should be noted that since it is difficult to set a telescopic rod at the connection position between the upper transmission column 231 and the lower connecting column 232, a first lifting ring 291 is provided at the top of the stirring ring 221, and a lifting column 292 is provided at the top of the first lifting ring 291. The lifting column 292 is connected to the top slider 34. When the top slider 34 is lifted or lowered, the lifting member 29 and the stirring member 22 are driven to lift or lower, thereby achieving the purpose of driving the lower connecting column 232 to lift or lower.

[0053] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
