Description

Technical Field

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

[0002] In the process of concentrating and crystallizing gibberellins (plant growth regulators), the concentrated crystallization liquid has poor fluidity due to its low water content. At the same time, when the gibberellins are concentrated and crystallized, the heat area provided by the evaporation heating device is fixed, which leads to uneven heating of the gibberellins when the stirring device stirs the gibberellins. In other words, it is difficult for the stirring device to fully stir the concentrated liquid with poor fluidity.

[0003] The invention 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, and the stirring device is used to stir and crystallize the gibberellin extract. The stirring device in the prior art has two stirring structures, upper and lower. However, this stirring device still has shortcomings when in use: 1. A circle of stirring rods is arranged on the stirring shaft, and the stirring rods push the concentrated liquid to move when the stirring shaft rotates, but due to the poor fluidity of the concentrated liquid, the local concentrated liquid cannot be stirred; 2. A rotating screw, a transmission disk and a rubber soft rod are arranged at the bottom of the stirring shaft. When the stirring shaft rotates, the transmission disk rotates up and down, and then the elastic lever on the transmission disk moves the concentrated liquid at the bottom of the crystallization tank, but because the crystallization tank is cylindrical, this kind of up and down stirring structure cannot stir the sediment at a local position.

[0004] To this end, the utility model provides a stirring device for producing a plant growth regulator. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a stirring device for the production of plant growth regulators to solve the problems raised in the above-mentioned background technology. The utility model has the advantages of improving the flow uniformity of the concentrated liquid and avoiding the formation of precipitates.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a stirring device for the production of plant growth regulators, comprising a stirring shaft located at the top of a crystallization tank, the outer peripheral wall of the stirring shaft is fixedly connected to two circumferentially evenly distributed suspension rods, the free end of the suspension rod is rotatably connected to the stirring rod, the rotation axis of the stirring rod is parallel to the axis of the stirring shaft, the stirring shaft is sleeved with a rotating sleeve, the outer peripheral wall of the rotating sleeve is fixedly connected to two circumferentially evenly distributed elastic telescopic rods, one end of the stirring rod is rotatably connected to the action end of the elastic telescopic rod.

[0007] Furthermore, the elastic telescopic rod includes a positioning sleeve, a supporting spring and a connecting rod, one end of the connecting rod is sleeved in the positioning sleeve and the other end is hingedly connected to the other end of the stirring rod, and the supporting spring is sleeved in the positioning sleeve and one end is connected to the other end of the connecting rod.

[0008] Furthermore, the outer wall of the stirring rod is fixedly connected with a positioning shaft near the middle, the free end of the suspension rod is fixedly connected with a support sleeve sleeved outside the positioning shaft, and the support sleeve is rotatably connected to the positioning shaft.

[0009] Furthermore, the outer peripheral wall of the connecting rod is fixedly connected with a push plate parallel to the connecting rod, and the push plate is inclined relative to the horizontal plane.

[0010] Furthermore, the push plate is provided with evenly distributed water holes.

[0011] Furthermore, the bottom of the positioning shaft is rotatably connected with a wave plate.

[0012] Furthermore, a row of evenly distributed spoilers is fixedly connected to the bottom of the stirring rod.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model arranges a rotating sleeve, an elastic telescopic rod and a stirring rod on the stirring shaft. When the stirring shaft rotates, connecting rods are arranged on the stirring rod and the elastic telescopic rod to form a V shape. The V shape can push the concentrated liquid to move to both sides, thereby pushing the concentrated liquid in the crystallization tank to move comprehensively, thereby facilitating improving the uniformity of heating of the concentrated liquid.

[0015] The utility model fixes a first row of spoilers at the bottom of the stirring rod. The spoilers change the position of their bottoms at the bottom of the crystallization tube as the stirring rod and the elastic telescopic rod change relative to each other, thereby avoiding the formation of precipitates and the problem of gibberellin inactivation due to local high temperature.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a stirring device for producing plant growth regulators, comprising a stirring shaft 1 located at the top of a crystallizer, a driving motor installed at the top outside the crystallizer, the top of the stirring shaft 1 extending out of the crystallizer and fixedly connected to the output shaft of the driving motor, wherein an electric heater can be installed in the crystallizer, and a heating coil can also be installed outside the crystallizer to provide a heating temperature for the crystallization of gibberellin liquid in the crystallizer.

[0022] In the present technical solution, the outer wall of the stirring shaft 1 is fixedly connected to two circumferentially evenly distributed suspension rods 11, and the free end of the suspension rod 11 is rotatably connected to the stirring rod 2, and the rotation axis of the stirring rod 2 is parallel to the axis of the stirring shaft 1. Specifically, the outer wall of the stirring rod 2 is fixedly connected to a positioning shaft 21 near the middle, and the free end of the suspension rod 11 is fixedly connected to a support sleeve 111 mounted on the outside of the positioning shaft 21, and the support sleeve 111 and the positioning shaft 21 are rotatably connected. When the two stirring rods 2 are collinear, the free ends of the stirring rods 2 and the inner wall of the crystallization tank are in a state of approximate contact, a rotating sleeve 3 is sleeved on the stirring shaft 1, and the outer peripheral wall of the rotating sleeve 3 is fixedly connected to two circumferentially evenly distributed elastic telescopic rods 4, one end of the stirring rod 2 and the action end of the elastic telescopic rod 4 are rotatably connected, one elastic telescopic rod 4 corresponds to one stirring rod 2, wherein the elastic telescopic rod 4 is in a contracted state under normal conditions, that is, when the stirring shaft 1 stops rotating, under the action of the elastic telescopic rod 4, the two stirring rods 2 are collinear, and when the stirring shaft 1 rotates, the stirring rod 2 will swing due to obstruction, and the elastic telescopic rod 4 will extend, at this time the elastic telescopic rod 4 and the stirring rod 2 will form a V shape.

[0023] Specifically, the elastic telescopic rod 4 includes a positioning sleeve 41, a support spring 42 and a connecting rod 43. One end of the connecting rod 43 is sleeved in the positioning sleeve 41 and the other end is hingedly connected to the other end of the stirring rod 2. The support spring 42 is sleeved in the positioning sleeve 41 and one end is connected to the other end of the connecting rod 43. The support spring 42 acts as a tension spring.

[0024] In this embodiment, the outer peripheral wall of the connecting rod 43 is fixedly connected with a push plate 431 parallel to the connecting rod 43. The push plate 431 can further improve the effect of the elastic telescopic rod 4 in pushing the concentrated liquid to move, that is, the push plate 431 can further increase the contact area between the elastic telescopic rod 4 and the concentrated liquid. The push plate 431 is inclined relative to the horizontal plane, and the push plate 431 has the function of pushing the concentrated liquid to flow obliquely upward or obliquely downward. Preferably, the push plate 431 is provided with evenly distributed water holes 4311. When the push plate 431 pushes the concentrated liquid, the concentrated liquid will accelerate through the water holes 4311, thereby increasing the flow speed of the concentrated liquid.

[0025] In this embodiment, the bottom of the positioning shaft 21 is rotatably connected with a wave plate 211, which is wavy and swings back and forth under the push of the fluid when following the movement of the positioning shaft 21. The swing can further push the concentrated liquid to move along the radial direction of the crystallization tank.

[0026] In this embodiment, a row of evenly distributed spoilers 22 are fixedly connected to the bottom of the stirring rod 2, and the bottom of the spoiler 22 extends to the bottom of the crystallization tank. When the stirring rod 2 swings, the bottom of the spoiler 22 moves radially while moving circumferentially relative to the crystallization tank, thereby effectively stirring the concentrated liquid and avoiding the formation of sediment.

[0027] Working principle: This stirring device replaces the stirring device in the patent document mentioned in the background technology. When in use, the stirring shaft 1 is controlled to rotate, and the gibberellin liquid is in a diluted state. At this time, the stirring resistance of the two stirring rods 2 is small and is in a state of being approximately collinear. As the crystallizer continues to be heated, the gibberellin liquid is gradually evaporated and forms a concentrated liquid. At this time, the resistance of the stirring rod 2 becomes larger, and the stirring rod 2 swings back with the positioning shaft 21 as the rotating axis. At the same time, the connecting rod 43 on the elastic telescopic rod 4 is pulled out, and the supporting spring 42 is stretched. At this time, the stirring rod 2 and the adjacent elastic telescopic rod 4 form a V-shape, and the tip of the V-shape faces the direction of movement. The concentrated liquid will be stirred, and at the same time, the concentrated liquid will be squeezed to both sides of the stirring direction to achieve comprehensive stirring of the concentrated liquid. In this process, the spoiler 22 is pressed against the bottom of the crystallizer to avoid the formation of sediment.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
