Description

Technical Field

[0001] The invention relates to the technical field of centrifugal dehydration, and in particular to a dehydration drying device and method for producing bromochlorohydantoin. Background Art

[0002] Bromochlorohydantoin is an important organic chemical raw material, widely used in pesticides, medicine, and the chemical industry, especially in the pharmaceutical industry. The production of bromochlorohydantoin often involves multiple steps, including solvent extraction, reaction synthesis, and subsequent dehydration and drying.

[0003] Currently, common methods for dehydrating bromochlorohydantoin include heating, vacuum drying, and centrifugal drying. During the centrifugal drying process, the high-speed centrifugal force can subject bromochlorohydantoin particles to mechanical stress, leading to particle breakage or material loss. This not only affects final product quality but can also result in yield losses, especially when maintaining particle integrity is crucial. A utility model patent (publication number: CN211552242U) discloses a centrifugal dehydration device comprising a barrel, wherein a servo motor is mounted on the lower end surface of the barrel, and a storage rack is mounted on the output shaft of the servo motor. The rack comprises an I-shaped plate fixedly connected to the servo motor output shaft in the middle portion of the lower surface. A first telescopic rod is mounted on the upper surface of the I-shaped plate, and a fastening knob is mounted on the upper end of the side of the fixed end of the first telescopic rod. A circular plate is mounted on the top of the first telescopic rod, and the circular plate has evenly distributed through-holes on its upper surface. The I-shaped plate has slots corresponding to the through-holes on its upper surface. An annular sponge pad is positioned within the barrel, its outer surface contacting the inner side surface of the barrel. Although this patent proposes the concept of using an annular sponge pad as a centrifugal filtration buffer, when applied to the filtration of bromochlorohydantoin particles of the present invention, due to the small size of the bromochlorohydantoin particles, the particles will be pressed and embedded in the sponge during the centrifugal filtration process. The water absorbed by the sponge can easily cause secondary contamination of the bromochlorohydantoin particles. The water in the sponge needs to be completely drained, which affects the filtration efficiency. Moreover, after the filtration is completed, the bromochlorohydantoin particles are easily adhered to the sponge, making discharge difficult. Therefore, it is urgently needed to provide a centrifugal dehydration and drying device specifically for small particles to meet the production requirements of bromochlorohydantoin.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Example 1, as Figures 1-6 As shown, a dehydration and drying device for the production of bromochlorohydantoin includes a dehydration tank 1, a centrifugal drum 2 is rotatably installed inside the dehydration tank 1, two groups of pressure rings 22 are provided inside the centrifugal drum 2, a multifunctional inner disk 4 is sandwiched between the two groups of pressure rings 22, and the multifunctional inner disk 4 is composed of two groups of conical disks and an intermediate tube. The two groups of conical disks are symmetrically distributed about the intermediate tube. The radius of the upper conical disk is smaller than the radius of the lower conical disk. A sponge liner 5 is provided between the multifunctional inner disk 4 and the centrifugal drum 2. The outer surface of the sponge liner 5 is provided with an external shaping member 51. The sponge liner 5 between the lower conical disk and the centrifugal drum 2 is tightly squeezed. The outer side of the lower conical disk is annularly provided with multiple groups of triangular transmission openings 41. The outer side of the centrifugal drum 2 is annularly provided with multiple groups of transmission boxes 23. The transmission block 24 is slidably connected to the transmission box 23. A top spring 25 is provided between the transmission block 24 and the transmission box 23. The transmission block 24 is plugged into the triangular transmission opening 41. The plug-in end of the transmission block 24 is arranged in a right triangle. A ball 26 is rotatably installed on the outer side of the straight side. Both ends of the intermediate tube are provided with a guide tube 6 that can be raised and lowered. A feeding tee tube 43 is provided in the middle of the intermediate tube. The feeding tee tube 43 can be inserted into the guide tube 6. The two ends of the outer shaping part 51 respectively pass through the corresponding multifunctional inner disk 4 and the pressure ring 22, and are respectively fixedly installed on the two groups of guide tubes 6.

[0021] The inner wall of the dehydration tank 1 is provided with two groups of inner partitions 11, and the centrifugal cylinder 2 is rotatably installed between the two groups of inner partitions 11. The top and bottom of the centrifugal cylinder 2 are provided with smoke exhaust pipes 13. The outside of the dehydration tank 1 is provided with a drain pipe 12, and the drain pipe 12 is located directly above the lower inner partition 11. A discharge valve 14 is provided at the bottom of the dehydration tank 1.

[0022] A drive motor 9 is fixedly installed at the bottom of the dehydration tank 1, and a drive wheel 10 is fixedly installed at the output end of the drive motor 9. The drive wheel 10 is located in the dehydration tank 1. A driven wheel 21 is fixedly installed at the bottom of the centrifugal cylinder 2. The drive wheel 10 is engaged with the driven wheel 21, and a lock is provided at the output end of the drive motor 9.

[0023] Loading: The upper conduit 6 descends to the bottom, and the conduit 6 gathers the excess part of the sponge liner 5 above the multifunctional inner plate 4, and the loading tee 43 is plugged into the bottom of the upper conduit 6. Then, bromochlorohydantoin particles are injected into the space between the sponge liner 5 and the multifunctional inner plate 4 through the conduit 6 and the loading tee 43 to complete the loading.

[0024] Centrifugal dehydration and drying: Start the equipment, drive motor 9 drives driving wheel 10 to rotate, driving wheel 10 drives centrifugal drum 2 to rotate through driven wheel 21. At this time, the vertical surface of transmission block 24 is in close contact with the vertical surface of triangular transmission port 41. Centrifugal drum 2 drives multifunctional inner disk 4 to rotate synchronously through transmission block 24. Centrifugal drum 2, multifunctional inner disk 4 and sponge liner 5 rotate synchronously. Bromochlorohydrazine particles are pressed on sponge liner 5 under the action of centrifugal force. Sponge liner 5 provides buffering force to bromochlorohydrazine particles and can absorb moisture to prevent bromochlorohydrazine particles from breaking.

[0025] After the slurry is dried, the upper and lower guide tubes 6 are rotated, and the lower guide tubes 6 are rotated, so that the lower end of the sponge liner 5 is rotated. Scraping, preliminarily removes the absorbed moisture, and can prevent bromochlorohydantoin particles from being taken out, and then hot air is introduced through the upper conduit 6, the hot air enters the multifunctional inner disk 4, blows downward to the gathered sponge liner 5, and performs secondary drying and water removal. After running for a period of time, the above method is used to control the upper and lower sets of conduits 6 to descend synchronously again, and the sponge liner 5 is better again. It should be noted that the radius of the upper cone disk is smaller than the radius of the lower cone disk. Therefore, the distance between the upper cone disk and the centrifugal cylinder 2 is larger, and the sponge liner 5 will not be scraped when passing through the distance. It will be scraped when entering between the upper pressure ring 22 and the upper cone disk. The scraped water will not flow back downward, and will be discharged to the bottom of the dehydration tank 1 under the guiding action of the multifunctional inner disk 4, and finally discharged through the discharge valve 14. The overall dehydration and drying efficiency is high, and secondary pollution is prevented. The dried sponge liner 5 has a certain stability, can indirectly perform thermal drying on the particles, and the drying is more stable. During the dehydration and drying process, the hot air after participating in the drying is discharged through the exhaust pipe 13 for centralized treatment.

[0026] Automatic and fast discharge: Since the discharge valve 14 performs a drainage operation during the dehydration and drying process, the residual water in the sponge liner 5 is a trace amount during the centrifugal dehydration process. Therefore, a small amount of water may hang on the wall at the bottom of the centrifugal cylinder 2 and the bottom of the dehydration tank 1. Therefore, it is necessary to first introduce hot air into the dehydration tank 1 through the upper conduit 6 for a period of time to evaporate the water. The trace water evaporates quickly, and generally 1 minute is enough. At this time, the output end of the drive motor 9 is locked with a lock, and the centrifugal cylinder 2 cannot rotate. At this time, the multifunctional inner disk 4 is controlled to rotate relative to the centrifugal cylinder 2, and the rotation direction is the same as the working direction of the centrifugal cylinder 2. Therefore, the multifunctional inner disk 4 is pushed through the triangular transmission port 41 and the inclined surface of the transmission block 24. The dynamic transmission block 24 slides to the inside of the transmission box 23. When the transmission block 24 is misaligned with the triangular transmission port 41, the triangular transmission port 41 is fully opened. At this time, the particles are discharged from the triangular transmission port 41. Since a cone disk is provided under the multifunctional inner disk 4, the particles will slide obliquely to the position of the triangular transmission port 41, and the particles can be completely discharged. When the transmission block 24 is aligned with the triangular transmission port 41 again, under the action of the top spring 25, the transmission block 24 knocks in the triangular transmission port 41, causing the centrifugal cylinder 2, the multifunctional inner disk 4 and the sponge liner 5 to vibrate, which can shake off the particles remaining in the sponge liner 5, ensuring complete discharge. The particles fall into the bottom of the dehydration tank 1 through the centrifugal cylinder 2 and are then discharged through the discharge valve 14.

[0027] Embodiment 2, based on the above embodiment, further includes: a spiral guide groove 42 is opened inside the intermediate tube, an outer spiral protrusion 61 is provided on the outer side of the conduit 6, the outer spiral protrusion 61 is threadedly connected in the spiral guide groove 42, and the thickness of the outer spiral protrusion 61 is less than the depth of the spiral guide groove 42.

[0028] Through the present embodiment, when the catheter 6 is inserted into the middle tube at the bottom, the catheter 6 rotates under the guidance of the outer spiral protrusion 61 and the spiral guide groove 42. It should be noted that the pitch of the spiral guide groove 42 is set to 5-10 cm. The pitch is large and can generate rotational drive. The catheter 6 will drive the sponge liner 5 to twist, which can just discharge the water absorbed inside it, and the sponge liner 5 can be switched alternately in a smaller space.

[0029] Since the thickness of the outer spiral protrusion 61 is smaller than the depth of the spiral guide groove 42, when the outer spiral protrusion 61 is threadedly connected to the spiral guide groove 42, there is an air cavity between the outer spiral protrusion 61 and the spiral guide groove 42, and the hot air is spirally discharged through the cavity so that the sponge liner 5 can be dried with hot air more evenly.

[0030] Through the arrangement of this embodiment, there is no need to give additional rotational drive to the multifunctional inner disk 4. During the discharge process, the conduit 6 is locked to restrict the rotation of the conduit 6. Then, when the conduit 6 is controlled to descend, the conduit 6 drives the multifunctional inner disk 4 to rotate, and the rotation direction is the same as the working direction of the centrifuge barrel 2. When rising, the conduit 6 is unlocked, and the conduit 6 rotates relative to the multifunctional inner disk 4. Therefore, as the conduit 6 moves up and down, the multifunctional inner disk 4 rotates unidirectionally to discharge.

[0031] Embodiment three, on the basis of the above embodiment, further includes: two groups of lifting cylinders 3 are fixedly installed on the outside of the dehydration tank 1, and the telescopic ends of the lifting cylinders 3 are fixedly installed with lifting rods 31, and the lifting tubes 7 are rotatably installed inside the lifting rods 31. The lifting tubes 7 are fixedly connected to the corresponding conduits 6, and the ends of the lifting tubes 7 away from the conduits 6 are fixedly installed with hot air pipes 8. A feeding branch pipe is provided on the outside of the upper hot air pipe 8, and a clamping cylinder 32 is fixedly installed on the top of the upper lifting rod 31. The telescopic end of the clamping cylinder 32 can clamp and fix the lifting tube 7 in the lifting rod 31.

[0032] The lifting rod 31 is controlled by the lifting cylinder 3, and the lifting rod 31 drives the guide tube 6 to move up and down through the lifting tube 7, which is simple to control; During the discharging process, when the control conduit 6 is lowered, the clamping cylinder 32 fixes the lifting tube 7 on the lifting rod 31, and the lifting tube 7 limits the rotation of the conduit 6. The conduit 6 drives the multifunctional inner disk 4 to rotate, and the rotation direction is the same as the working direction of the centrifuge cylinder 2. When rising, the clamping cylinder 32 releases the lifting tube 7, the conduit 6 is unlocked, and the conduit 6 rotates relative to the multifunctional inner disk 4. Therefore, as the conduit 6 moves up and down, the multifunctional inner disk 4 rotates unidirectionally to perform discharging.

[0033] Embodiment 4, based on the above embodiment, further includes that the top of the lower inner partition 11 is tilted outward. This design facilitates the discharge of centrifugally shed water during centrifugal dehydration and drying.

[0034] Furthermore, the bottom of the centrifugal cylinder 2 is conical. This design can guide the particles during discharge, resulting in a good discharge effect.

[0035] Embodiment 5, based on the above embodiment, further includes that the outer shaping member 51 is composed of multiple groups of pull ropes arranged in a ring shape on the outside of the sponge liner 5. Through the setting of the pull ropes, the transmission stability is ensured while the overall buffering effect on the sponge liner 5 is small, and the sponge liner 5 can be prevented from being pulled apart.

[0036] Embodiment 6, based on the above embodiment, further includes that the outer shaping member 51 adopts an outer wrapping net. The arrangement of this embodiment has a certain impact on the dehydration efficiency, but the impact is relatively small, but the anti-breaking effect is better.

[0037] Example 7, a dehydration and drying method for producing bromochlorohydantoin, comprising the following steps: S1, loading: through the feeding branch pipe, bromochlorohydantoin chemical synthesis particles are injected into the equipment by compressed air, and enter the centrifuge cylinder 2 through the conduit 6 and the feeding tee pipe 43; S2, dehydration and drying: Start the equipment, centrifuge drum 2 centrifuges and dehydrates the bromochlorohydantoin chemical synthesis particles, and the sponge liner 5 plays a protective and water-absorbing function, thereby improving the efficiency of centrifugal dehydration and drying. During the centrifugal dehydration process, the upper and lower guide tubes 6 are alternately raised and lowered to achieve the position replacement of the sponge liner 5 and the removal of water from the sponge, thereby completing high-speed and high-quality dehydration and drying; S3, unloading: turn off the equipment, stop the centrifuge cylinder 2, and then control the multifunctional inner disk 4 to rotate relative to the centrifuge cylinder 2. When the transmission block 24 disengages from the triangular transmission port 41, the dehydrated and dried bromochlorohydantoin chemical synthesis particles are discharged through the triangular transmission port 41, and then open the discharge valve 14 to discharge the material.

[0038] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
