Technical Field

[0001] This utility model relates to the field of plant growth regulator crystallization technology, specifically a crystallization device for plant growth regulators. Background Technology

[0002] Plant growth regulator pesticides include naphthaleneacetic acid, gibberellin, and 6-BA. Among them, 6-BA is a white or off-white crystal in physical form. 6-BA pesticides are generally in powder form and are widely used in agriculture, horticulture, and forestry. In the production process of 6-BA pesticides, crystallization equipment is required to carry out crystallization process in order to purify the active ingredient.

[0003] Chinese patent application CN 110115855 A discloses a special crystallization tank for gibberellin plant growth regulator; it includes a tank body; a stirring device is provided on the tank body for stirring and crystallizing gibberellin extract, and an evaporation device is provided inside the bottom of the tank body for evaporating the liquid in the gibberellin to accelerate the crystallization of gibberellin; a thermometer is provided inside the tank body, and a guide plate is provided at the bottom of the tank body; an elastic actuating rod provided on the rotating disk can both slide and rotate at the bottom of the tank body, increasing the stirring area and stirring rate at the bottom of the tank body, thereby enabling rapid stirring and crystallization of gibberellin precipitated at the bottom of the tank body, preventing the poor fluidity of concentrated gibberellin from causing precipitation of the crystallized gibberellin; at the same time, it prevents the local temperature of the gibberellin extract from becoming too high due to precipitation of crystallized gibberellin, thus preventing inactivation.

[0004] Existing plant growth regulators are prone to clogging during the crystallization process after crystallization, resulting in low feeding efficiency due to the inability to easily feed the crystals. Therefore, a crystallization device for plant growth regulators is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a crystallization device for plant growth regulators.

[0006] The technical solution adopted by this utility model to solve its technical problem is a crystallization device for plant growth regulators, including a base, an outer tank mounted on the base via a bracket, a PLC controller mounted on the side wall of the outer tank, multiple lifting slots opened on the inner wall of the outer tank, lifting blocks assembled in the lifting slots, an inner tank mounted on the lifting blocks, and a vibration assembly mounted on the inner tank; the vibration assembly includes springs, multiple springs are installed between the inner wall of the outer tank and the top plate of the inner tank, a piston-type pneumatic vibrator is mounted on the inner wall of the outer tank, the piston of the piston-type pneumatic vibrator is fixedly connected to the bottom wall of the inner tank via a connecting block, a first air guide pipe is mounted on the piston-type pneumatic vibrator, and an air compressor is mounted on the base via a machine base. A second air guide pipe is connected to the air compressor, and a pressure reducing valve is connected to the other end of the second air guide pipe. The pressure reducing valve is fixedly installed on the base and is connected to the other end of the first air guide pipe. The air compressor provides air power to the piston-type pneumatic vibrator through the second air guide pipe and the first air guide pipe, driving the piston to move back and forth continuously, causing the piston-type pneumatic vibrator to generate vibration force. The piston moves back and forth in the vertical direction, thereby driving the inner tank to move back and forth in the vertical direction. Therefore, the inner tank vibrates slightly. This structure causes the inner tank to vibrate slightly during the feeding process of prismatic white crystals, breaking the blockage that easily forms at the discharge port of prismatic crystals, improving the fluidity of the crystals, accelerating the feeding speed of the crystals, and improving the feeding efficiency of the device.

[0007] Preferably, a feed pipe and a water inlet pipe are installed on the top plate of the inner tank, and a sealing cap is installed on the feed pipe. A discharge pipe is installed at the bottom of the inner tank, and a valve is installed on the discharge pipe. A drive motor is installed on the top plate of the outer tank via a base. A telescopic coupling is installed on the output shaft of the drive motor, and a stirring rod is installed at the other end of the telescopic coupling. A stirring blade is installed on the stirring rod, which is assembled into the inner tank. A heating plate is installed inside the side wall of the inner tank. A laser probe is installed on the inner wall of the top plate of the inner tank. A water storage tank is installed on the base via a bracket. A first water guide pipe is installed on the bottom side of the water storage tank, and an electric... A solenoid valve is used. The other end of the first water guide pipe is connected to a peristaltic pump. The peristaltic pump is connected to a second water guide pipe, the other end of which is connected to an inlet pipe. The second water guide pipe is used to guide water from the storage tank into the inner tank through the first water guide pipe, the second water guide pipe, and the inlet pipe. A laser probe monitors the inner tank in real time, monitoring the number and size distribution of crystal particles. When the solution becomes slightly turbid, crystals begin to grow, eventually resulting in prismatic white crystals. During this process, the stirring blades continuously stir the material and scrape off the material from the inner wall, preventing material from clumping together and improving the efficiency of plant growth regulator crystallization.

[0008] The advantages of this utility model are:

[0009] 1. This utility model uses an air compressor to provide air power to a piston-type pneumatic vibrator through a second air pipe and a first air pipe. This drives the piston to reciprocate continuously, causing the piston-type pneumatic vibrator to generate vibration force. The piston reciprocates vertically, thereby causing the inner tank to move vertically. As a result, the inner tank vibrates slightly. This structure causes the inner tank to vibrate slightly during the feeding process of prismatic white crystals, breaking up the blockage that easily forms at the discharge port of prismatic crystals, improving the fluidity of the crystals, accelerating the feeding speed of the crystals, and improving the feeding efficiency of the device.

[0010] 2. This invention uses a peristaltic pump to guide water from the storage tank into the inner tank through the first water guide pipe, the second water guide pipe, and the inlet pipe. A laser probe monitors the inner tank in real time, tracking the number and size distribution of crystal particles. When the solution becomes slightly turbid, crystals begin to grow, eventually resulting in prismatic white crystals. During this process, the stirring blades continuously stir the material and scrape off material from the inner wall, preventing material from clumping together and improving the efficiency of plant growth regulator crystallization.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3 As shown, a crystallization device for plant growth regulators includes a base 1, an outer tank 2 mounted on the base 1 via a bracket, a PLC controller 3 mounted on the side wall of the outer tank 2, multiple lifting slots 201 formed on the inner wall of the outer tank 2, lifting blocks 202 assembled within the lifting slots 201, an inner tank 4 mounted on the lifting blocks 202, and a vibration assembly mounted on the inner tank 4; the vibration assembly includes springs 5, multiple springs 5 ​​are installed between the inner wall of the outer tank 2 and the top plate of the inner tank 4, a piston-type pneumatic vibrator 501 is mounted on the inner wall of the outer tank 2, the piston of the piston-type pneumatic vibrator 501 is fixedly connected to the bottom wall of the inner tank 4 via a connecting block, a first air guide pipe 502 is mounted on the piston-type pneumatic vibrator 501, and an air compressor 503 is mounted on the base 1 via a base, a second air guide pipe 504 is connected to the air compressor 503, and the second air guide pipe... The other end of pipe 504 is connected to a pressure reducing valve 505, which is fixedly installed on the base 1. The pressure reducing valve 505 is connected to the other end of the first air guide pipe 502. During operation, after the existing plant growth regulators have crystallized, blockage is likely to occur during the feeding process. Due to the inability to easily feed the crystals, the feeding efficiency of the device is low. Plant growth regulator pesticides include naphthaleneacetic acid, gibberellin, 6-BA, etc. Among them, 6-BA is in the physical form of white or off-white crystals. 6-BA pesticides are generally in powder form. As a plant growth regulator, 6-BA is widely used in agriculture, horticulture and forestry. It has the effects of inhibiting chlorophyll decomposition, delaying aging and promoting cell division. In the production process of 6-BA pesticides, a crystallization device is required to carry out the crystallization process to purify the active ingredients.

[0020] After 6-BA crystallization, prismatic white crystals are obtained. Then, the valve is turned to open the discharge pipe 403, and the crystals are discharged from the inner tank 4. During this process, the air compressor 503 (Ingersoll Rand SSR-EP30 model) is controlled by the PLC controller 3. The air compressor 503 provides air power to the piston-type pneumatic vibrator 501 through the second air pipe 504 and the first air pipe 502. The piston-type pneumatic vibrator 501 (QZD140 model) operates by using the high-pressure gas discharged from the air compressor 503 as the air source, driving the piston to continuously reciprocate, thus generating vibration force in the piston-type pneumatic vibrator 501. The piston reciprocates vertically, thereby causing the inner tank 4 to reciprocate vertically, causing it to vibrate vertically. The pressure reducing valve 505 (YK43X model) is adjusted to throttle the exhaust gas. The amplitude of the piston is controlled to be within 1-3mm. At the same time, the spring 5 absorbs the high-frequency impact energy through elastic deformation, converting the violent pulse vibration into low-frequency micro-amplitude vibration. Therefore, the inner tank 4 vibrates slightly. The telescopic coupling 601 is model GCLD1. The telescopic coupling 601 is a device that can compensate for the relative displacement of two shafts and transmit torque. Therefore, the stirring rod 602 on the telescopic coupling 601 can vibrate slightly. This structure causes the inner tank 4 to vibrate slightly during the feeding process of prismatic white crystals, which breaks the blockage that prismatic crystals are prone to form at the discharge port, improves the fluidity of the crystals, speeds up the feeding speed of the crystals, and helps to improve the feeding efficiency of the device.

[0021] Please see Figure 4-5As shown, the inner tank 4 has a feed pipe 401 and a water inlet pipe 402 installed on its top plate. A sealing cap is installed on the feed pipe 401. A discharge pipe 403 is installed at the bottom of the inner tank 4, and a valve is installed on the discharge pipe 403. A drive motor 6 is mounted on the top plate of the outer tank 2 via a base. A telescopic coupling 601 is mounted on the output shaft of the drive motor 6. A stirring rod 602 is mounted on the other end of the telescopic coupling 601. A stirring blade 603 is mounted on the stirring rod 602. The stirring rod 602 is assembled into the inner tank 4. A heating plate 604 is installed inside the side wall of the inner tank 4. A laser probe 609 is installed on the inner wall of the top plate of the inner tank 4. A water storage tank 605 is mounted on the base 1 via a bracket. A first water guide pipe 606 is installed on the bottom side of the water storage tank 605. A solenoid valve is installed on the first water guide pipe 606. A peristaltic pump 607 is connected to the other end of a water guide pipe 606. A second water guide pipe 608 is connected to the peristaltic pump 607. The other end of the second water guide pipe 608 is connected to the inlet pipe 402. The second water guide pipe 608 is a flexible hose. During operation, the existing crystallization device is difficult to crystallize the material efficiently during the crystallization of plant growth regulators. It is easy for the wall to form, resulting in poor crystallization efficiency. The 6-BA acetone solution is prepared in the previous step of the crystallization process by pouring 6-BA acetone solution into the inner tank 4 through the feed pipe 401. The 6-BA acetone solution is prepared by adding crude 6-BA to acetone and stirring at 40-45℃ until completely dissolved, about 30 minutes. Then, it is filtered with a 0.22μm filter membrane to remove insoluble impurities to obtain the 6-BA acetone solution.

[0022] During the crystallization and purification of 6-BA, the heating plate 604 of the inner tank 4 is controlled by the PLC controller 3. The heating plate 604 heats the inner wall of the inner tank 4, which in turn heats the 6-BA acetone solution, maintaining the solution temperature at approximately 25°C. Simultaneously, the PLC controller 3 controls the operation of the peristaltic pump 607 (model L / S Easy-Load II). The peristaltic pump 607 guides water from the water storage tank 605 into the inner tank 4 through the first water guide pipe 606, the second water guide pipe 608, and the inlet pipe 402. The peristaltic pump 607 can control the water flow rate, allowing water to be slowly added at a rate of 2 mL / min. A laser probe 609 (model Mettler Toledo) monitors the inner tank 4 in real time, tracking the number and size distribution of crystal particles and sending monitoring signals to the PLC controller 3. When the FBRM solution becomes slightly turbid, crystals begin to grow. Once the 6-BA acetone solution reaches supersaturation, water addition is stopped, and the solution is allowed to mature for 30 minutes. Crystals continue to grow gradually. Then, water is added dropwise at a lower rate of 0.5 mL / min until the total volume ratio is water:acetone = 1.5:1. Stirring is maintained for 4-6 hours to allow the crystals to grow completely, ultimately yielding prismatic white crystals. During this process, the drive motor 6 operates, rotating the telescopic coupling 601. The telescopic coupling 601 rotates the stirring rod 602, which in turn rotates the stirring blade 603. The stirring blade 603 continuously stirs the material and scrapes away material from the inner wall, preventing material from clumping and improving the efficiency of plant growth regulator crystallization.

[0023] Working principle: Existing crystallization devices struggle to efficiently crystallize plant growth regulators, often resulting in wall sludge formation and poor crystallization efficiency. This is addressed by pouring a 6-BA acetone solution into the inner tank 4 through the feed pipe 401. The 6-BA acetone solution is prepared in the preceding step of the crystallization process by adding crude 6-BA to acetone and stirring at 40-45°C until completely dissolved (approximately 30 minutes). Afterward, it is filtered through a 0.22μm filter membrane to remove insoluble impurities, yielding the 6-BA acetone solution. During the crystallization and purification of 6-BA, the heating plate 604 in the inner tank 4 is controlled by a PLC controller 3. The heating plate 604 heats the inner wall of the inner tank 4, which in turn heats the 6-BA acetone solution, maintaining the solution temperature at approximately 25°C. Simultaneously, the PLC controller 3 controls the operation of a peristaltic pump 607 (model L / S Easy-Load). II. The peristaltic pump 607 guides water from the storage tank 605 into the inner tank 4 through the first water guide pipe 606, the second water guide pipe 608, and the inlet pipe 402. The peristaltic pump 607 can control the flow rate of the water, allowing the water to be slowly added at a rate of 2 mL / min. The laser probe 609 monitors the inner tank 4 in real time, monitoring the number and size distribution of crystal particles, and sends monitoring signals to the PLC controller 3. The laser probe 609 is a Mettler Toledo FBRM. When the solution becomes slightly turbid, crystals begin to grow. When the 6-BA acetone solution reaches the supersaturation point, water addition is stopped, and the solution is allowed to mature for 30 minutes. The crystals gradually grow, and then water is added again at a lower rate of 0.5 mL / min until the water-to-acetone ratio is water:acetone = 1.A 5:1 ratio of stirring is maintained for 4-6 hours to allow for complete crystal growth, ultimately yielding prismatic white crystals. During this process, the drive motor 6 operates, rotating the telescopic coupling 601. The telescopic coupling 601 then rotates the stirring rod 602, which in turn rotates the stirring blades 603. The stirring blades 603 continuously stir the material and scrape away material from the inner wall, preventing material from clumping and improving the efficiency of plant growth regulator crystallization. Existing plant growth regulators often experience blockages during the feeding process after crystallization, resulting in low feeding efficiency due to the inability to easily feed the crystals. This issue is addressed by using plant growth regulators, including naphthaleneacetic acid. The pesticides used include acids, gibberellins, and 6-BA. 6-BA is a white or off-white crystalline powder, typically used as a plant growth regulator in agriculture, horticulture, and forestry. It inhibits chlorophyll decomposition, delays senescence, and promotes cell division. The production of 6-BA involves a crystallization process to purify the active ingredient. After crystallization, prismatic white crystals are obtained. The valve is then turned to open the discharge pipe 403, allowing the crystals to drain from the inner tank 4. During this process, the PLC controller 3 controls the operation of the air compressor 503 (model Ingersoll Rand). The SSR-EP30 air compressor 503 provides air power to the piston-type pneumatic vibrator 501 through the second air guide pipe 504 and the first air guide pipe 502. The piston-type pneumatic vibrator 501 is model QZD140. The operating principle of the piston-type pneumatic vibrator 501 is that the high-pressure gas discharged from the air compressor 503 serves as the air source power, driving the piston to continuously reciprocate in a cyclical motion, thus generating vibration force in the piston-type pneumatic vibrator 501. The piston reciprocates vertically, thereby causing the inner tank 4 to reciprocate vertically, causing the inner tank 4 to vibrate vertically. The pressure reducing valve 505 is model YK43X; adjusting the pressure reducing valve 505 throttles the exhaust gas. The piston amplitude is controlled to be within 1-3 mm. Simultaneously, spring 5 absorbs high-frequency impact energy through elastic deformation, converting the intense pulse vibration into low-frequency micro-amplitude vibration. Therefore, the inner tank 4 vibrates slightly. The telescopic coupling 601, model GCLD1, is a device capable of compensating for relative displacement between two shafts and transmitting torque. Therefore, the stirring rod 602 on the telescopic coupling 601 can vibrate slightly. This structure, by causing the inner tank 4 to vibrate slightly during the feeding of prismatic white crystals, breaks up the blockage that easily forms at the outlet of the prismatic crystals, improves the crystal's fluidity, accelerates the crystal feeding speed, and improves the efficiency of the feeding process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
