Description

Technical Field

[0001] The invention relates to the technical field of ethephon separation, and in particular to an experimental separation device and method for a plant growth regulator containing ethephon. Background Art

[0002] Ethephon is a plant growth regulator that can release ethylene and has many effects on plant growth, such as promoting maturity, shedding, dwarfing plants, inducing flowering, and affecting sexual differentiation. Currently, by obtaining mixed systems such as plant extracts, fermentation broths or synthetic reactants containing ethephon, and using corresponding separation devices to separate other impurities or components therefrom, higher purity ethephon components can be obtained.

[0003] Authorized patent CN110115855A discloses a special crystallization tank for gibberellin plant growth regulator; it comprises 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, so as to prevent 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 preventing the inactivation phenomenon.

[0004] The special crystallization tank for gibberellins plant growth regulators in the above-mentioned patent can also be applied to the crystallization separation of ethephon, which is a plant growth regulator of the same category, when in use. However, due to the lack of an effective impurity removal mechanism for the extract, the impurities and other solvent components such as water in the extract are too high, which will not only lead to reduced crystallization separation efficiency and purity, but also increase heating energy consumption; after the crystallization separation is completed, the elastic toggle rods distributed circumferentially on the rotating disk rotate to clean the crystals adhered to the guide plate, and it is difficult for the elastic toggle rods to fully contact the surface of the guide plate, resulting in the existence of cleaning dead corners; when the elastic toggle rods intermittently squeeze the guide plate, although an air bag is provided at the bottom of the guide plate to make it vibrate, the vibration effect is relatively weak, and the cleaning effect on the crystals adhered to the dead corner area on the guide plate is limited, which is not convenient for the rapid discharge of the crystals.

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Embodiment 1 like Figure 1-Figure 10 As shown, a plant growth regulator experimental separation device containing ethephon component comprises a separation tank 1, a support leg 11 is arranged at the bottom of the separation tank 1, a liquid inlet pipe 12 and a liquid discharge valve pipe 13 are fixedly plugged on the upper and lower sides of the separation tank 1, a temperature sensor 14 is fixedly connected to the left wall of the inner cavity of the separation tank 1, a negative pressure pipe 15 is fixedly plugged on the top of the separation tank 1, a sealing filter screen 21 is rotatably connected to the upper side of the inner cavity of the separation tank 1, a separation filter screen 24 is fixedly connected to the upper side of the inner cavity of the separation tank 1, the sealing filter screen 21 can seal the bottom of the separation filter screen 24 and the two have the same specifications, an arc scraper 22 is arranged on the upper wall of the separation filter screen 24, and the arc scraper 22 can rotate synchronously with the sealing filter screen 21; A plurality of T-shaped limit strips 17 in a circumferential array are fixedly connected to the inner wall of the separation tank 1, a clamping ring 3 slidably connected to the inner wall of the separation tank 1 is slidably connected to the T-shaped limit strip 17, a rubber convex 32 is fixedly connected to the inner wall at the bottom of the clamping ring 3, a T-shaped blocking block 33 is fixedly connected to the inner wall at the top of the clamping ring 3, a support rod 34 is fixedly connected to the bottom of the clamping ring 3, a discharge pipe 35 slidably plugged with the bottom of the separation tank 1 is fixedly connected between the support rods 34, an elastic core tube 36 is slidably connected to the top of the discharge pipe 35, the T-shaped blocking block 33 can seal the top of the elastic core tube 36, and a filter membrane 37 is fixedly connected between the top of the elastic core tube 36 and the rubber convex 32; The inner wall of the clamping ring 3 is rotatably connected to the gear ring 4, a driving motor is arranged in the left wall cavity of the separation tank 1, and the output end of the driving motor is fixedly connected to a driving gear 5 meshing with the gear ring 4, an electric heating ring 41 is slidably clamped on the inner wall of the gear ring 4, and three groups of stirring components are arranged between the electric heating ring 41 and the elastic core tube 36.

[0021] When in use, the plant growth regulator extract containing ethephon is added into the separation tank 1 through the liquid inlet pipe 12. The extract automatically flows through the separation filter 24 and the sealing filter 21 with aligned filter holes under the action of gravity. The separation filter 24 automatically intercepts the larger volume of solid impurities in the extract flowing through. The filtered extract flows to the filter membrane 37. Some substances with molecular volume smaller than ethephon automatically pass through the filter membrane 37 and enter the bottom of the inner cavity of the separation tank 1. After the extract completely flows to the filter membrane 37, the sealing filter 21 and the arc scraper 22 are controlled to rotate synchronously, and the rotation direction is The curved side of the arc scraper 22 rotates a certain number of times and then stops. The arc scraper 22 automatically scrapes the impurities on the upper surface of the separation filter 24 and gathers toward the middle. The filter holes on the sealing filter 21 are just misaligned with the filter holes on the separation filter 24. The sealing filter 21 seals the bottom of the separation filter 24. The elastic core tube 36 controls the T-shaped block 33 to move the clamp ring 3 upward, and the filter membrane 37 moves upward. The extraction liquid is pressurized by the sealed separation filter 24, and the remaining part of the substances with a molecular volume smaller than ethephon and solvents such as water are pressed out through the filter membrane 37 and enter the bottom of the inner cavity of the separation tank 1; After the pressurized impurity removal, the control device is reset, and the negative pressure pipe 15 is controlled to operate to extract the collected solid impurities and form a negative pressure inside the separation tank 1, and the electric heating ring 41 is controlled to heat the remaining extract, and the ethephon component in the extract is gradually concentrated and crystallized. In this process, the separation filter 24 and the filter membrane 37 are used to passively remove impurities from the extract containing ethephon. After the passive impurity removal, the remaining extract on the filter membrane 37 is controlled to be pressurized for active impurity removal, thereby maximizing the reduction of impurities and solvents such as water in the extract, improving the subsequent crystallization separation efficiency and purity, and reducing heating energy consumption. Later, when heating for concentration and crystallization, the temperature sensor 14 automatically monitors the heating temperature and feedback-adjusts the heating power of the electric heating ring 41 to ensure that the heating temperature is appropriate. During this period, the driving gear 5 is controlled to drive the gear ring 4 to make the stirring component rotate continuously, which can ensure that the extract is heated evenly. The filter membrane 37 is stretched downwards due to the limit of the T-shaped limit strip 17 on the clamping ring 3, and the elastic part of the elastic core tube 36 is stretched, and the elastic core tube 36 drives the filter membrane 37 to stretch downwards in a cone shape. The stirring assembly also follows the filter membrane 37 to tilt and rotate automatically to move the crystals on the filter membrane 37, and the top of the filter membrane 37 automatically shakes in coordination, so that the crystals on the filter membrane 37 are cleaned without dead angles. The cleaned crystals automatically slide down and enter through the port opened at the top of the elastic core tube 36 and are quickly discharged outwards from the discharge pipe 35. The corresponding impurities, water and other solvents can be discharged in coordination with the opening of the discharge valve pipe 13.

[0022] Embodiment 2, based on the above embodiment, provides an adjustment mechanism for the sealing filter screen 21, the arc scraper 22 and the elastic core tube 36: like Figure 3-Figure 4 and Figure 6 As shown, a rotating tube 2 is rotatably connected to the top of the inner cavity of the separation tank 1, the bottom of the rotating tube 2 is fixedly connected to the sealing filter 21, the separation filter 24 is movably sleeved on the outer periphery of the rotating tube 2, and a twist groove 23 is opened on the inner wall of the rotating tube 2. The twist groove 23 is composed of a spiral groove in the middle and straight grooves on the upper and lower sides. A screw rod 6 is slidably inserted in the rotating tube 2, a T-shaped blocking block 33 is movably provided at the bottom of the screw rod 6, and is fixedly connected to the inner wall of the elastic core tube 36 through a connecting rod, a pin protrusion 61 movably engaged with the torsion groove 23 is provided on the right wall of the screw rod 6, and a driving screw rod 62 is threadedly inserted at the top of the screw rod 6, and the driving screw rod 62 is driven by a forward and reverse motor arranged at the top of the separation tank 1.

[0023] Furthermore, the arc scraper 22 is fixedly connected to the periphery of the rotating tube 2 , the number of the arc scraper 22 is three and they are distributed around the circumference, and the arc scraper 22 is movably in contact with the upper surface of the separation filter 24 .

[0024] Initially, the pin convex 61 on the right wall of the screw 6 is movably engaged with the bottom of the spiral groove in the twisted groove 23. After the separation filter 24 is used to completely filter the extract onto the filter membrane 37, the forward and reverse motors are controlled to drive the driving screw 62 to rotate forward to move the screw 6 upward. The screw 6 drives the pin convex 61 upward to move the spiral groove in the twisted groove 23, so that the rotating tube 2 drives the arc scraper 22 to rotate toward its curved side. The arc scraper 22 automatically scrapes the impurities on the upper surface of the separation filter 24 and gathers toward the middle. The three arc scrapers 22 can avoid scraping omissions. The synchronous rotating tube 2 drives the sealing filter 21 to rotate. When the pin convex 61 moves up to the top of the spiral groove in the twisted groove 23, the filter holes on the sealing filter 21 are just misaligned with the filter holes on the separation filter 24, and the sealing filter 21 seals the bottom of the separation filter 24. As the forward and reverse motors drive the driving screw 62 to continue to rotate forward, the pin convex 61 moves upward along the upper straight groove in the twisted groove 23, and the separation filter 24 is stably sealed. The screw 6 initially drives the elastic core tube 36 to squeeze the T-shaped block 33, so that the clamping ring 3 moves up a distance and then continues to move up. The extract on the filter membrane 37 is thus sealed and filtered to remove most impurities, water and other solvents, so as to improve the subsequent crystallization rate. Subsequently, the forward and reverse motors are controlled to drive the driving screw 62 to reverse and reset and then continue to reverse. The pin protrusion 61 moves downward along the lower straight groove in the torsion groove 23. The sealing filter 21 and the arc scraper 22 do not work. The screw 6 drives the elastic core tube 36 to move downward to open the top port of the elastic core tube 36 to release the crystals, which is easy to control.

[0025] Embodiment 3, based on the above embodiment, provides a structure of an elastic core tube 36 and a T-shaped block 33: like Figure 6 As shown, the top end surface of the elastic core tube 36 is inclined inwardly, and the bottom end surface of the T-shaped blocking block 33 is adapted to the elastic core tube 36 .

[0026] When the filter membrane 37 filters and concentrates the crystals, the slope that matches the top of the elastic core tube 36 and the bottom of the T-shaped block 33 can prevent the extract from leaking. When the elastic core tube 36 moves downward relative to the T-shaped block 33 to release the crystals, a slope can be provided for the crystals that slide off the filter membrane 37 to slide out, thereby ensuring smooth release of the crystals.

[0027] Embodiment 4, based on the above embodiment: like Figure 2-Figure 3 As shown, the negative pressure pipe 15 is externally connected to a negative pressure suction device, and a negative suction cover 16 is fixedly connected to the bottom of the negative pressure pipe 15 , and the negative suction cover 16 is movably sleeved on the outer periphery of the rotating pipe 2 and is located on the upper side of the arc scraper 22 .

[0028] When the extract is heated, concentrated and crystallized, the negative pressure pipe 15 is used to generate low pressure by suction, which is convenient for low-pressure volatilization of the solvent and discharge of steam, and the crystallization separation efficiency is fast; the negative suction hood 16 is used to increase the suction range, so as to stably suck and separate the solid impurities gathered in the center on the filter screen 24, so as to facilitate the secondary use of the separation filter screen 24.

[0029] Embodiment 5, based on the above embodiment, provides a vibration adjustment mechanism for the filter membrane 37: like Figure 7-Figure 9 As shown, an annular wave groove 31 is provided on the inner wall at the top of the clamping ring 3, and a pin convex 42 movably engaged with the wave groove 31 is fixedly connected to the inner wall of the electric heating ring 41. There are four pin convex 42 and they are distributed in a circle. A plurality of balls in a circular array are movably engaged with the bottom of the electric heating ring 41, and the balls movably abut against the rubber along the convex 32.

[0030] When the gear ring 4 drives the electric heating ring 41 to rotate, the four circumferentially distributed pin protrusions 42 are driven by the annular wave groove 31 to drive the electric heating ring 41 to move back and forth up and down, and the stirring component is then driven to oscillate, and the electric heating ring 41 intermittently squeezes the elastic rubber protrusion 32, and the rubber protrusion 32 drives the edge of the filter membrane 37 to vibrate, so that when the extract is heated, concentrated and crystallized, the extract is oscillated to facilitate uniform heating, or when the filter membrane 37 is stretched and tilted to release the crystals, the discharge of the crystals is accelerated; and the rubber protrusion 32 is squeezed by the ball, so that excessive wear of the rubber protrusion 32 when the electric heating ring 41 rotates is avoided.

[0031] Embodiment 6, based on the above embodiment, provides a stirring component structure: like Figure 6-Figure 7 and Fig.10 As shown, the stirring assembly includes a telescopic sleeve 43 movably hinged on the inner wall of the electric heating ring 41, a plurality of linearly distributed stirring blades 44 are fixedly connected to the upper wall of the telescopic sleeve 43, a soft rubber strip 1 45 is fixedly connected to the bottom of the telescopic sleeve 43, a telescopic core rod 46 is slidably clamped on the side of the telescopic sleeve 43 close to the elastic core tube 36, a soft rubber strip 2 47 is fixedly connected to the side of the bottom of the telescopic core rod 46 away from the soft rubber strip 1 45, and a bearing ring 38 is rotatably connected to the top of the elastic core tube 36, and the bearing ring 38 is movably hinged to the telescopic core rod 46.

[0032] Furthermore, the bottom of the first soft rubber strip 45 and the bottom of the second soft rubber strip 47 are both configured to be wavy, and the bottom of the first soft rubber strip 45 and the bottom of the second soft rubber strip 47 are both movably abutted against the upper surface of the filter membrane 37 .

[0033] When the gear ring 4 drives the electric heating ring 41 to rotate, under the rotation of the bearing ring 38, the telescopic sleeve 43 movably hinged to the electric heating ring 41 and the telescopic core rod 46 movably hinged to the bearing ring 38 are driven to rotate synchronously, and the stirring blade 44, the soft rubber strip 1 45 and the soft rubber strip 2 47 on the telescopic core rod 46 can simultaneously oscillate and stir when the extract is concentrated and crystallized to ensure uniform heating, and the filter membrane 37 is stretched and tilted to release the crystals when discharging, and the electric heating ring 41 reciprocates up and down, which can drive the telescopic sleeve 43 to rotate synchronously. The tube 43 is inserted and pulled relative to the telescopic core rod 46. When the soft rubber strip 1 45 is rotated to clean the crystals adhered to the filter membrane 37, it can also move back and forth radially along the filter membrane 37 to clean. After the crystals cleaned at the edge slide to the middle of the filter membrane 37, the telescopic core rod 46 that only rotates to clean drives the soft rubber strip 2 47 to use the sliding crystals to achieve a better squeezing and cleaning effect on the crystals adhered to the center area. In addition, the wavy design at the bottom of the soft rubber strip 1 45 and the soft rubber strip 2 47 can enhance the cleaning effect on the adhered crystals.
