Description

Technical Field

[0001] The utility model relates to the technical field of gibberellin processing, in particular to a crystallization device for plant growth regulators. Background Art

[0002] Gibberellic acid, as a highly efficient and broad-spectrum plant growth hormone, is widely used in agricultural and forestry production and beer fermentation. With the promotion of hybrid rice seed production technology and the continuous expansion of fruit and vegetable planting, the commercial demand for gibberellins is also increasing, but the high price of gibberellins limits its further use. In the process of producing and extracting gibberellins, since gibberellins are easily hydrolyzed and inactivated when the concentration temperature is higher than 50°C, the usual crystallization process is divided into two steps. First, the extract is concentrated and crystallized at 30°C to 40°C, and then the crystals are formed by subsequent placement. In the process of concentration and crystallization, due to the low water content of the concentrated crystallization liquid, poor fluidity will be caused; at the same time, when the gibberellins are concentrated and crystallized, the area of ​​heat provided by the evaporation heating device is fixed, which leads to the phenomenon that the stirring device is prone to uneven heating of the gibberellins when stirring the gibberellins, and then the gibberellins are locally overheated when concentrated, which leads to the phenomenon that the gibberellins are easily hydrolyzed and inactivated.

[0003] To this end, the utility model with publication number CN110115855B proposes a special crystallization tank for gibberellin plant growth regulator; it includes a tank body; a stirring device is arranged on the tank body, the stirring device is used to stir and crystallize the gibberellin extract, and an evaporation device is arranged inside the bottom end of the tank body, the evaporation device is used to evaporate the liquid in the gibberellin, so as to accelerate the crystallization of the gibberellin; a thermometer is arranged inside the tank body, and a material guide plate is arranged at the bottom end of the tank body; an elastic toggle rod arranged on the rotating disk can both slide and rotate at the bottom end of the tank body, thereby increasing the stirring area and stirring rate of the elastic toggle rod at the bottom end of the tank body, and then the gibberellin precipitated at the bottom end of the tank body can be quickly stirred and crystallized, preventing the concentrated gibberellin from having poor fluidity and causing the crystallized gibberellin to precipitate; at the same time, it is prevented that the local temperature of the gibberellin extract is too high due to the precipitation of the crystallized gibberellin, thereby causing inactivation.

[0004] However, the above-mentioned prior art sets a large number of mechanisms in the crystallization tank to solve the problem of uneven heating of gibberellins. The mechanisms are not only complicated but also affect the conduction of heat and the discharge of crystals after crystallization, which means that the practicality is poor.

[0005] To this end, the utility model provides a crystallization device for plant growth regulators. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a crystallization device for plant growth regulators to solve the problems raised in the above-mentioned background technology. The utility model not only has a simple structure, but also has the advantages of improving the fluidity of gibberellins, improving the uniformity of heating of gibberellins, and having the advantage of smoother material discharge.

[0007] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a crystallization device for plant growth regulators, comprising a crystallization tank, the bottom of the crystallization tank is in the shape of a hemispherical shell, an evaporation spherical shell near the bottom is rotatably connected in the crystallization tank, the rotation axis of the evaporation spherical shell is perpendicular to the axis of the crystallization tank and an arc scraper is fixedly connected to its outer peripheral wall, the number of the arc scrapers is at least three and they are evenly distributed circumferentially relative to the rotation axis of the evaporation spherical shell, and the outer spherical wall of the evaporation spherical shell is provided with an inlet located on one side of the arc scraper and outlets near both ends of the arc scraper.

[0008] Furthermore, a positioning tube is passed through and fixedly connected to the outer spherical wall of the evaporating spherical shell. The positioning tube is rotatably connected to the inner circumferential wall of the crystallizing tank and a bypass tube is fixedly connected thereto. The bypass tube is fixedly connected to the inner spherical wall of the evaporating spherical shell.

[0009] Furthermore, the bypass pipe is in a wave-breaking shape and is evenly distributed circumferentially relative to the positioning pipe.

[0010] Furthermore, the outer peripheral wall of the crystallization tank is fixedly connected to a motor seat, a driving motor is fixedly arranged on the motor seat, an output shaft of the driving motor is fixedly connected to a driving gear, and one end of the positioning tube is fixedly sleeved with a transmission gear meshing with the driving gear.

[0011] Furthermore, both ends of the positioning tube are rotatably connected with a transfer tube.

[0012] Furthermore, the arc scraper is tilted relative to the axis of the evaporating spherical shell, and the outer edge of the arc scraper is provided with resistance reducing notches evenly arranged along the length direction.

[0013] Furthermore, a feed pipe is fixedly connected to the bottom of the crystallization tank, a conveying auger is arranged in the feed pipe, and a discharge pipe is fixedly connected to the outer peripheral wall of the feed pipe, and a valve is serially connected to the discharge pipe.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model arranges an evaporating ball at the bottom of a crystallizing tank, and an arc-shaped scraper, an inlet and an outlet on the evaporating ball. When the evaporating ball rotates, it can drive the gibberellin stock solution to flow. Moreover, since the rotation axis of the evaporating ball is perpendicular to the axis of the crystallizing tank, the flowing gibberellin stock solution is in a turbulent state, which can effectively avoid the problem of precipitation.

[0016] The utility model provides an evaporating ball with a positioning tube, an inlet, an outlet and an arc-shaped scraper. The evaporating ball is rotatably arranged, which can improve the fluidity of the gibberellin stock solution and has the advantages of simple structure and greater practicality.

[0017] The utility model arranges a bypass pipe fixedly connected to the inner wall of the evaporating ball on the outer periphery of the positioning pipe, so that the entire evaporating ball and its internal components are in a heating state, thereby heating the gibberellin liquid, and the gibberellin is heated more evenly.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a crystallization device for plant growth regulators, comprising a crystallization tank 1, and a feeding port is arranged on the top of the crystallization tank 1. The bottom of the crystallization tank 1 is in the shape of a hemispherical shell, and an evaporation spherical shell 2 near the bottom is rotatably connected in the crystallization tank 1. The evaporation spherical shell 2 is arranged near the bottom of the crystallization tank 1, and the evaporation spherical shell 2 has a heating function, and the purpose is to provide a crystallization temperature for the gibberellin stock solution.

[0024] The rotation axis of the evaporation spherical shell 2 is perpendicular to the axis of the crystallization tank 1 and an arc scraper 3 is fixedly connected to its outer peripheral wall. The outer edge of the arc scraper 3 below the evaporation spherical shell 2 contacts the spherical shell inner wall in the crystallization tank 1. When the evaporation spherical shell 2 rotates, the arc scraper 3 will scrape the spherical wall in the crystallization tank 1 to avoid precipitation.

[0025] The number of the arc scrapers 3 is at least three and they are evenly distributed circumferentially relative to the rotation axis of the evaporation spherical shell 2. The outer spherical wall of the evaporation spherical shell 2 is provided with an inlet 21 located on one side of the arc scraper 3 and an outlet 22 near both ends of the arc scraper 3. When the evaporation spherical shell 2 rotates, the arc scraper 3 will push the gibberellin stock solution, and the gibberellin stock solution will enter the evaporation spherical shell 2 through the inlet 21, and then be discharged from the outlet 22, thereby realizing turbulence control of the gibberellin stock solution.

[0026] Among them, the outer spherical wall of the evaporation spherical shell 2 is penetrated and fixedly connected with a positioning tube 23, the positioning tube 23 is rotatably connected to the inner circumferential wall of the crystallization tank 1 and a bypass tube 231 is fixedly connected thereto. Specifically, both ends of the positioning tube 23 are rotatably connected with a transfer tube 5, the transfer tube 5 is fixedly connected to the crystallization tank 1 and one end thereof is rotatably connected to the positioning tube 23, and the transfer tube 5 is connected to an external liquid pipe. The bypass tube 231 is fixedly connected to the inner spherical wall of the evaporation spherical shell 2, and a heated liquid flows through the positioning tube 23. The function of the bypass tube 231 is to transfer heat to the evaporation spherical shell 2, the purpose is to improve the uniformity of heating of the evaporation spherical shell 2, and then to evenly heat the gibberellin stock solution flowing through. Preferably, the bypass tube 231 is in a wave-breaking shape and is circumferentially evenly distributed relative to the positioning tube 23.

[0027] In this embodiment, the outer peripheral wall of the crystallization tank 1 is fixedly connected to a motor base 11, and a driving motor 4 is fixedly arranged on the motor base 11. The output shaft of the driving motor 4 is fixedly connected to a driving gear 41, and one end of the positioning tube 23 is fixedly sleeved with a transmission gear 232 meshing with the driving gear 41, and the driving motor 4 provides driving force for the rotation of the positioning tube 23.

[0028] In this embodiment, the arc scraper 3 is tilted relative to the axis of the evaporation spherical shell 2, that is, the axes of the arc scraper 3 and the evaporation spherical shell 2 are not in the same plane, and the outer edge of the arc scraper 3 is provided with resistance reduction notches 31 evenly arranged along the length direction. The arc scraper 3 can also transmit gibberellin crystal particles when moving with the evaporation spherical shell 2, and the crystal particles can be driven to move to the bottom of the crystallization tank 1 by controlling the forward and reverse rotation of the evaporation spherical shell 2.

[0029] Furthermore, a feed pipe 12 is fixedly connected to the bottom of the crystallization tank 1. The feed pipe 12 is a transmission pipe for discharging crystal particles. A conveying auger 8 is arranged inside the feed pipe 12. When the conveying auger 8 rotates, the crystal particles can be transmitted outward. A discharge pipe 121 is fixedly connected to the outer peripheral wall of the feed pipe 12. A valve 9 is connected in series to the discharge pipe 121. When the control valve 9 is opened, the crystal particles in the discharge pipe 121 are discharged.

[0030] Working principle: Put the gibberellin stock solution through the feed port of the crystallizer 1, and then inject the heating liquid into the positioning tube 23. The positioning tube 23 and the bypass tube 231 through which the heating liquid flows are both in a heating state. At the same time, the evaporation spherical shell 2 is heated by the bypass tube 231 and is also in a heating state. Start the driving motor 4, and the positioning tube 23 is driven to rotate. At this time, the arc scraper 3 will push the liquid, and the liquid is introduced into the evaporation spherical shell 2 through the inlet 21, and then discharged outward through the outlet 22. In this process, the liquid is fully and evenly heated by the evaporation spherical shell 2, and no sediment is formed. When the crystal particles are generated, the evaporation spherical shell 2 is controlled to rotate, and then the valve 9 is controlled to open, and then the conveying auger 8 is started, and the crystal particles will be discharged outward by the conveying auger 8 to achieve material discharge control.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
