Description

Technical Field

[0001] The present invention relates to the technical field of propiconazole purification, and specifically relates to a propiconazole purification device. Background Art

[0002] Propiconazole is a highly effective systemic fungicide widely used in the agricultural field. It can inhibit the biosynthesis of fungal cell membranes, thereby effectively controlling various crop diseases, such as wheat rust, rice sheath blight, etc., which is of great significance for ensuring the yield and quality of crops. In order to ensure an increase in the content of the active ingredient of propiconazole, more effectively inhibit the growth and reproduction of fungi, and better control crop diseases such as wheat rust and rice sheath blight, purification treatment is usually required. The main purification methods of propiconazole include distillation, recrystallization, extraction, etc.

[0003] Existing crystallization purification devices usually need to stir and cool the solution. The reason is that stirring can promote the uniform distribution of solutes, accelerate mass transfer, and prevent local overheating. Cooling can reduce the solubility of solutes, control the crystal growth rate, and improve the crystallization yield. The combined action of the two ensures the effect and efficiency of crystallization purification. However, the existing stirring mechanisms usually adopt a fixed stirring speed and cannot be adjusted according to changes in the solution concentration and crystallization degree. When the solution concentration is high, if the stirring speed is insufficient, it will lead to uneven solute distribution and affect crystal growth. When the solution concentration is low, continuous high-speed stirring will increase energy consumption and may even damage the formed crystal structure. In terms of cooling, the cooling temperature and stirring speed of traditional cooling mechanisms are fixed and cannot meet the temperature requirements for propiconazole crystallization at different stages. Too high or too low cooling temperatures will affect crystal formation and purity, reducing product quality. Summary of the Invention

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: 1. By the light emitted by the semi-circular lamp panel in the detection mechanism, the solution concentration affects the absorption and scattering of light, changes the light intensity irradiated on the photoresistive plate, and further changes the resistance value of the photoresistive plate. When the solution concentration is high, the light intensity is weak, the resistance value is large, the current passing through the electromagnet is large, the magnetism of the electromagnet is strong, the permanent magnet on the sliding plate is repelled to slide upward, the L-shaped conductive sheet slides upward on the resistance strip, the resistance of the sliding rheostat decreases, the current passing through the adaptive adjustment circuit increases, the motor speed increases, and the stirring speed increases; when the solution concentration is low, the opposite is true. The stirring speed can be adjusted in real time according to the solution concentration. When the concentration is high, the stirring is accelerated to promote the uniform distribution of the solute. When the concentration is low, the rotation speed is reduced to reduce energy consumption and avoid damage to the crystal structure, effectively improving the crystallization purification efficiency and product quality.

[0014] 2. As crystallization progresses, crystals continuously precipitate from the solution. The scattering and absorption of light by the crystals increase, the light intensity irradiating the photoresistor plate weakens, the resistance value increases, and the PLC controller monitors the current change through the current monitoring module to feedback the crystallization speed. When the crystallization speed is too slow, the PLC controller controls some electromagnetic blocks to cut off the power, and some permanent magnetic blocks and gear blocks retract, disengaging from the second gear to achieve intermittent stirring. Moreover, the slower the crystal formation speed, the more gear blocks the PLC controller controls to retract to increase the intermittent duration, avoiding excessive disturbance to the solution system during continuous stirring, preventing damage to the crystal growth environment and affecting the normal growth of crystals. On the other hand, it promotes solute diffusion and crystal nucleation during stirring and allows the crystals to grow fully when stationary, which helps to improve the crystal purity and crystallinity.

[0015] 3. Similarly, based on the principle that the resistance value of the photoresistor plate in the detection mechanism changes with the solution concentration and crystallization degree, when the solution concentration is high, the resistance value is large, the electromagnet has strong magnetism, the sliding plate moves upward, and the L-shaped conductive sheet slides upward on the resistance bar. The resistance of the sliding rheostat decreases, the current passing through the adaptive adjustment circuit increases, the refrigeration power of the refrigeration plate increases, the cooling water temperature decreases, and at the same time, the motor speed increases, and the stirring speed of the cooling water also increases. When the solution concentration is low, the opposite occurs, achieving the adaptive adjustment of the cooling temperature and stirring speed according to the temperature requirements of propiconazole crystallization in different stages, avoiding the problems of traditional cooling mechanisms that affect crystal formation and purity and reduce product quality due to fixed cooling temperatures and fixed stirring speeds.

[0026] The adaptive cooling mechanism 5 further includes a cooling water tank 52. A refrigeration plate is embedded in the inner wall of the cooling water tank 52. A water pump 54 and a drainage pump 55 are fixedly connected to the top end of the cooling water tank 52. The water pumping end of the water pump 54 is fixedly communicated with the inner bottom wall of the cooling water tank 52.

The water pumping end of the drainage pump 55 is fixedly communicated with a water suction pipe 57. The other end of the water suction pipe 57 is connected to the bottom of the cooling cavity 51. The water drainage end of the drainage pump 55 is communicated with the cooling water tank 52. The sliding rheostat is electrically connected to the motor 41 and the refrigeration plate to form an adaptive adjustment circuit. During the process of the L-shaped conductive sheet 38 sliding upward on the resistance strip 36, the current passing through the adaptive adjustment circuit gradually increases; The water pump 54 and the drainage pump 55 work together to realize the circulation of the cooling water between the cooling water tank 52 and the cooling cavity 51.

[0027] The outer wall of the rotating rod 42 is fixedly connected with a telescopic shell 58. The inner wall of the telescopic shell 58 is slidably connected with a telescopic rod 59. The bottom end of the telescopic rod 59 is fixedly connected with a mixing plate 510. The outer wall of the mixing plate 510 is fixedly connected with stirring blades 511. A limiting groove 512 is formed in the inner top wall of the fixed cover 2, and the center of the limiting groove 512 coincides with the center of the fixed cover 2. A rotating column 53 is rotatably connected to the inner wall of the limiting groove 512. The rotating column 53 is fixedly connected with the top end of the telescopic rod 59.

[0028] The working principle of the present invention is as follows: Open the sealing plug 12, pour the propiconazole solution that needs to go through the crystallization purification step after treatment into the purification tank 1 through the feed port at the top of the fixed cover 2, and then re-seal the sealing plug 12.

[0029] Then start the semi-circular lamp board and the photoresistor board 31. The light emitted by the semi-circular lamp board passes through the transparent board 33 and irradiates into the solution. The concentration of the solution will affect the absorption and scattering of the light, thereby changing the light intensity irradiated on the photoresistor board 31. The resistance value of the photoresistor board 31 will change with the change of the light intensity. The lower the solution concentration, the stronger the light intensity and the smaller the resistance value; the higher the solution concentration, the weaker the light intensity and the larger the resistance value. Among them, the blockage of light by the stirring rod 49 has been pre-calculated in the influence on the photoresistor. Since in the start-up circuit formed by the photoresistor board 31 and the electromagnet 39, the magnetic strength of the electromagnet 39 is affected by the resistance value of the photoresistor board 31. When the solution concentration is high, the light intensity irradiated on the photoresistor board 31 is weak, the resistance value is large, the current passing through the electromagnet 39 is large, the electromagnet 39 has strong magnetism, repels the permanent magnet on the sliding plate 37, makes the sliding plate 37 slide upward against the elastic force of the non-magnetic spring 310. The L-shaped conductive sheet 38 at the top end of the sliding plate 37 slides upward on the resistance strip 36. The resistance of the sliding rheostat formed by the L-shaped conductive sheet 38 and the resistance strip 36 decreases, and the current passing through the adaptive adjustment circuit increases. Therefore, the rotation speed of the motor 41 increases and the refrigeration power of the refrigeration plate increases. Since the rotation speed of the motor 41 increases, the stirring speed of the solution increases, and the stirring speed of the cooling water increases. Since the refrigeration power of the refrigeration plate increases, the temperature of the cooling water decreases; on the contrary, when the solution concentration is low, the rotation speed of the motor 41 slows down, the stirring speed decreases, the refrigeration power of the refrigeration plate decreases, the temperature of the cooling water rises, and the stirring speed of the cooling water slows down. As the crystallization progresses, the solution concentration gradually decreases. Therefore, according to the above principle, the stirring speed of the solution, the cooling speed of the cooling water, and the stirring speed of the cooling water can be adaptively adjusted.

[0030] As crystallization progresses, crystals continuously precipitate from the solution, the solution concentration decreases, and at the same time, the scattering and absorption of light by the crystals increase, weakening the light intensity incident on the photoresistor plate 31. The photoresistor plate 31 has the property of changing its resistance value with the change of light intensity. When the light intensity weakens, its resistance value increases. At this time, the current monitoring module in the PLC controller monitors the current passing through the photoresistor, and then the crystallization rate is reflected through the current change.

[0031] When the crystallization rate is too slow, intermittent stirring will be started. In this case, the crystal growth in the solution is relatively slow. Continuous stirring for a long time will not only increase energy consumption but also may cause unnecessary interference to the solution system, affecting the normal growth of crystals. At this time, the PLC controller no longer energizes some of the electromagnetic blocks 47. Therefore, some of the permanent magnet blocks 46 and tooth blocks 48 retract under the action of the plastic spring 45, and some of the tooth blocks 48 disengage from the second gear 410, and the stirring rod 49 no longer continuously obtains power, thus realizing intermittent stirring.

[0032] During the intermittent stirring process, the motor 41 drives the rotating rod 42 and the circular plate 43 to rotate periodically. When the non-retracted tooth block 48 meshes with the second gear 410, the stirring rod 49 is driven to rotate, and the stirring plate 411 stirs the solution, enabling the solute in the solution to be evenly distributed, providing a relatively stable environment for crystal growth; when the tooth block 48 disengages from the second gear 410, the stirring rod 49 stops rotating, and the solution is in a relatively static state, giving the crystals enough time to grow slowly.

[0033] This intermittent stirring mode effectively avoids excessive disturbance to the solution system caused by continuous stirring. In the case of slow solution crystallization, excessive stirring may destroy the stable environment required for crystal growth, resulting in disordered crystal growth and even possible fragmentation of the formed tiny crystal nuclei, affecting the normal growth of crystals. Intermittent stirring can not only promote solute diffusion and crystal nucleation during stirring but also allow the crystals to grow fully during the static stage, helping to improve the purity and crystallinity of the crystals; Moreover, the slower the crystal formation rate, the longer the intermittent duration usually is. The reason is as follows: A slow crystal formation rate means that the crystal growth process in the solution is relatively slow, and it is necessary to minimize external interference and give the crystals enough time to grow naturally. A longer intermittent duration can reduce the number of stirring times, reduce the interference of stirring on the solution system, and prevent the destruction of the crystal growth environment due to excessive stirring, affecting the normal growth and crystallization effect of crystals. Therefore, the PLC controller needs to control more tooth blocks 48 to retract to increase the stirring intermittent duration. On the contrary, fewer tooth blocks 48 need to be controlled to retract to reduce the stirring intermittent duration.
