Detailed Implementation
[0030] 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 protection scope of the present utility model.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a polycarboxylate superplasticizer reaction apparatus, comprising a reaction vessel 1, which is the core component and the site for the reaction of the polycarboxylate superplasticizer, providing space for the mixing and reaction of various raw materials. An insulation shell 2 is provided on the outside of the reaction vessel 1 to reduce heat loss during the reaction process and maintain a suitable temperature environment required for the reaction. A drive motor 3 is provided at the bottom of the reaction vessel 1 to provide power to a stirring element 4. The stirring element 4 is provided on the inner wall of the reaction vessel 1 and rotates with the operation of the drive motor 3, enhancing the fluidity of the raw materials and allowing different components to react. The raw materials are in full contact, which improves the uniformity and rate of the reaction. The lower part of the stirring component 4 is fixedly connected to the upper part of the output shaft of the drive motor 3. The upper part of the reaction vessel 1 is equipped with a mixing mechanism, which includes a transmission component and a dispersion component. The transmission component includes a hopper 51, which is fixedly connected to the upper part of the reaction vessel 1 and is used to transport the reagents required for the reaction. The left side of the hopper 51 is equipped with a movable door for adding reagents. The upper part of the hopper 51 is fixedly connected to a fixed shell 52, which provides an installation and support structure for the transmission components such as the drive motor 53, the rotating shaft 54, the worm gear 55, and the worm wheel 56.
[0032] Reference Figure 3 and Figure 5 A second drive motor 53 is installed on the upper part of the fixed shell 52 as the power source of the transmission component. A rotating shaft 54 is fixedly connected to the lower part of the output shaft of the second drive motor 53. The rotating shaft 54 rotates under the drive of the second drive motor 53, which drives the worm 55 and the rotating rod 6 to rotate. The rotating rod 6 is slidably connected to the outside of the rotating shaft 54. A stirring rod 7 is fixedly connected to the outside of the rotating rod 6. Multiple sets of stirring rods 7 are provided to drive multiple sets of stirring rods 7 to rotate, preventing the agent from clogging in the hopper 51. At the same time, the up and down movement of the rotating rod 6 drives the distribution plate 83 to vibrate, so that the agent can be evenly dispersed in the reaction vessel 1. A worm 55 is installed on the outside of the rotating shaft 54 and meshes with a worm wheel 56 to transmit the rotation of the rotating shaft 54 to the worm wheel 56. The worm wheel 56 meshes on the outside of the worm 55 and rotates under the drive of the worm 55, which drives the fixed plate 57 to rotate. The worm wheel 56 is rotatably connected to the inner wall of the fixed shell 52.
[0033] Furthermore, the transmission assembly also includes a fixed disk 57, which is fixedly connected to the outside of the worm gear 56. The connection between the fixed disk 57 and the worm gear 56 is offset from the center point of the fixed disk 57. When the fixed disk 57 rotates, due to the eccentric setting, the connecting piece 58 will move up and down, thereby driving the rotating rod 59 to swing, causing the rotating rod 6 to move up and down reciprocally, enhancing the mixing effect. The connecting piece 58 is rotatably connected to the outside of the fixed disk 57 for connecting the fixed disk 57 and the rotating rod 59. The rotating rod 59 is rotatably connected to the lower part of the connecting piece 58 for connecting the connecting piece 58 and the rotating rod 6. The rotating rod 59 is slidably connected to the inner wall of the fixed shell 52. A bearing is fixedly connected to the left side of the rotating rod 59 to reduce the friction when the rotating rod 6 is rotating. The inner side of the bearing is fixedly connected to the outside of the rotating rod 6.
[0034] Reference Figure 3 and Figure 4 The dispersion component includes a fixing member 81, which is slidably connected to the lower part of the hopper 51. The fixing member 81 connects and supports the distributing strip 82 and the distributing plate 83. With the cooperation of the sliding rod 84 and the sleeve 85, the dispersion component can move up and down stably to ensure uniform dispersion of the agent. The lower part of the fixing member 81 is fixedly connected to the distributing strip 82. Multiple sets of distributing strips 82 are arranged in a circumferential array around the center point of the distributing plate 83. The distributing strips 82 uniformly disperse the agent entering from the hopper 51 into the reactor 1, increasing the dispersion area of the agent, preventing agent accumulation, and making the agent more evenly distributed in the reactor 1, thereby improving the reaction efficiency. The lower part of the distributing strip 82 is fixedly connected to the distributing plate 83. The upper side of the distributing plate 83 is set as a conical surface. The conical surface helps to guide the agent to disperse in all directions. Together with the distributing strip 82, it further improves the dispersion effect of the agent. The distributing plate 83 moves under the drive of the rotating rod 6, making the dispersion of the agent in the reactor 1 more uniform.
[0035] Furthermore, a sliding rod 84 is fixedly connected to the upper part of the fixing component 81, and a sleeve 85 is slidably connected to the outer side of the sliding rod 84. The sleeve 85 is fixedly connected to the inner wall of the reactor 1. The lower part of the rotating rod 6 is rotatably connected to the inner wall of the distribution plate 83. Four sets of sliding rods 84 and sleeves 85 are provided, and the four sets of sliding rods 84 and sleeves 85 are distributed in a circumferential array around the center point of the fixing component 81. The sliding rods 84 and sleeves 85 cooperate to provide a stable up and down sliding track for the fixing component 81 and the dispersion component, ensuring the stability of the dispersion component during the movement process, so that the agent can be evenly dispersed in the reactor 1.
[0036] Working principle: When in use, open the movable door on the left side of hopper 51, add the reagent required for the reaction into hopper 51, start drive motor 2 53, its output shaft drives the rotating shaft 54 to rotate, the worm 55 on the rotating shaft 54 rotates accordingly, the worm 55 meshes with the worm wheel 56, driving the worm wheel 56 to rotate, the fixed disk 57 fixedly connected to the outside of the worm wheel 56 also rotates. Since the connection between the fixed disk 57 and the worm wheel 56 is off from the center point of the fixed disk 57, when the fixed disk 57 rotates, the connecting piece 58 will move up and down, thereby driving the rotating rod 59 to swing on the inner wall of the fixed shell 52. The left side of the rotating rod 59 is connected to the rotating rod 6 through a bearing. The swing of the rotating rod 59 causes the rotating rod 6 to rotate and move up and down reciprocally at the same time.
[0037] The reciprocating motion of the rotating rod 6 drives the distribution plate 83 to vibrate. The upper side of the distribution plate 83 is a conical surface. The agent entering from the hopper 51 falls onto the distribution plate 83. Under the guidance of the conical surface, the agent is dispersed in all directions and then further evenly dispersed into the reaction vessel 1 by the distribution bar 82. Four sets of sliding rods 84 slide on the inner wall of the sleeve 85, providing a stable up and down sliding track for the fixing part 81, ensuring the stable movement of the distribution plate 83 and the distribution bar 82, and achieving uniform dispersion of the agent.
[0038] Multiple sets of stirring rods 7, which are fixedly connected to the outside of the rotating rod 6, rotate with the rotating rod 6 to stir the medicine in the hopper 51, preventing the medicine from clogging and improving the uniformity of mixing different medicines.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
