Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a multifunctional stirrer for liquid-liquid self-priming spray mixing. Background Art

[0002] Traditional agitators generally have structures such as blade type, turbine type, frame type and anchor type. The stirring parts only have the function of pure stirring and have a single function. When a traditional agitator is stirring, the position of the material does not change much. At the same time, when the vortex formed by the material reaches a certain level, some of the material will settle at the bottom, forming a stirring blind spot. For example, in reactor distillation, when the material occupies half of the reactor cavity, the material is only stirred in this half of the reactor during the stirring process. However, because the material cannot contact the upper part of the reactor, the heat of the upper part of the reactor cannot be used for distillation, which wastes heating energy. As the distillation progresses, the material becomes less and less, and the heat energy waste increases. In addition, when the traditional agitator stirs to a certain extent, due to the regular movement of the material, the internal state gradually reaches a dynamic equilibrium state, and the distillation effect gradually decreases.

[0003] Therefore, it is necessary to provide a multifunctional agitator for liquid-liquid self-priming spray mixing. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional agitator for liquid-liquid self-priming spray mixing to solve the problems of heat energy waste in the upper half of the reactor and a stirring blind area at the bottom of the reactor in the existing stirring process.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multifunctional agitator for liquid-liquid self-priming spray mixing, comprising:

[0007] A stirring shaft, one end of which is rotatably connected to the top of the reaction container and the other end of which extends into the interior of the reaction container;

[0008] A plurality of stirring rods with hollow structures are spaced a predetermined distance from the stirring shaft and arranged in a circular array with the stirring shaft as the center, and the stirring shaft is fixedly connected to the stirring rods through a bracket;

[0009] Among them, the top end of the stirring rod is a closed structure, the bottom end of the stirring rod is provided with a suction port, the upper halves of the multiple stirring rods are vertically arranged, and the lower halves of the multiple stirring rods are bent toward the center until they intersect and connect at the bottom ends; the upper half of the stirring rod is provided with multiple discharge holes at intervals on one side close to the reaction container.

[0010] Furthermore, there are multiple brackets, and the middle part of the stirring shaft is fixedly connected to the top of the stirring rod and the upper half of the stirring rod through the brackets, and the bottom end of the stirring shaft is fixedly connected to the lower half of the stirring rod through the brackets.

[0011] Furthermore, the reaction container is a reactor, and the top of the reactor is detachably connected to a top cover, the middle of the top cover is provided with an opening, the top of the top cover is connected to a drive motor, the end of the stirring shaft away from the stirring rod passes through the opening and is drivingly connected to the driving end of the drive motor, and the stirring shaft is rotatably connected to the opening via a bearing.

[0012] Furthermore, the top of the reactor is provided with a feed port, the bottom of the reactor is provided with a discharge port, and the suction port is arranged corresponding to the discharge port.

[0013] Furthermore, the discharge hole is spaced a predetermined distance from the side wall of the reactor, so that the liquid discharged from the discharge hole splashes onto the side wall of the reactor.

[0014] Furthermore, the spacings between the plurality of discharge holes are equal.

[0015] The present invention has the following beneficial effects:

[0016] 1. The agitator in the present invention has the function of self-priming spraying while rotating and stirring. In addition to the rotating mixing outside, the material also enters the spiral rising mixing inside the stirring rod, and then falls back into the material below after being discharged through the discharge hole for aggregation. In short, in addition to the traditional horizontal vortex mixing (first curve), the material also has vertical circulation mixing (second curve) and spiral rising mixing inside the agitator (third curve). The three mixing methods go hand in hand to make the materials mixed evenly and thoroughly, avoiding the existence of a stirring blind spot at the bottom of the reactor.

[0017] 2. In the present invention, the material is thrown out from the discharge hole of the stirring rod by centrifugal force and splashed onto the heating wall of the reactor. The material contacts the upper part of the reactor and can fully utilize the heat of the upper part of the reactor for distillation, saving heating energy consumption.

[0018] 3. The agitator in the present invention can suck the material from the bottom and splash it onto the upper edge of the heating surface of the reactor from the top, breaking the internal balance of the material, making full use of the heating surface, and maximizing the use of heat energy. The efficiency is shortened from the original 2 hours to 1 hour, which is significantly improved, and the distillation temperature is also greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Reference Figure 1-Figure 6 The embodiment of the present invention proposes a multifunctional agitator for liquid-liquid self-priming spray mixing, including: one end of the agitator shaft 3 is rotatably connected to the top of the reaction container, and the other end extends to the interior of the reaction container.

[0028] In this embodiment, the reaction container is preferably a reactor 1, and the top of the reactor 1 is detachably connected to a top cover 5, an opening is provided in the middle of the top cover 5, and a drive motor 6 is connected to the top of the top cover 5. The end of the stirring shaft 3 away from the stirring rod 2 passes through the opening and is driven and connected to the driving end of the drive motor 6. The stirring shaft 3 is rotatably connected to the opening through a bearing.

[0029] The plurality of hollow stirring rods 2 are spaced apart from the stirring shaft 3 by a predetermined distance and are arranged in a circular array with the stirring shaft 3 as the center. The stirring shaft 3 is fixedly connected to the stirring rod 2 via a bracket 4 .

[0030] The top of the stirring rod 2 is a closed structure, the bottom of the stirring rod 2 is provided with a suction port 201, the upper halves of the plurality of stirring rods 2 are vertically arranged, and the lower halves of the plurality of stirring rods 2 are bent toward the center until the bottom ends intersect and connect; a plurality of discharge holes 202 are provided at intervals on one side of the upper half of the stirring rod 2 close to the reaction container. The spacing between the plurality of discharge holes 202 is equal. The discharge holes 202 are spaced a predetermined distance from the side wall of the reactor 1 so that the liquid discharged from the discharge holes 202 splashes onto the side wall of the reactor 1.

[0031] In this embodiment, the number of stirring rods 2 is three. It can be understood that the stirrer is composed of three stirring rods 2. The upper parts of the three rods are vertically upright with equal spacing, and the lower parts are bent toward the center so that the bottoms of the three rods intersect, serving as the suction port 201 (such as Figure 3 ); The interior of each stirring rod 2 is a hollow structure with a closed top, and the outer side of the upper portion of the stirring rod 2 has equidistant openings as discharge holes 202 (such as Figure 2 ); a stirring shaft 3 is provided in the middle of the three stirring rods 2, and is connected to each stirring rod 2 through a bracket 4 to ensure that the stirrer structure is stable, strong and durable. The stirring shaft 3 can be connected to the driving end of the driving motor 6 to drive the stirrer to rotate.

[0032] At the same time, the top of the reactor 1 has a feed port, the bottom of the reactor 1 has a discharge port 101, and the suction port 201 is arranged corresponding to the discharge port 101, so that the materials accumulated at the discharge port 101 are mixed evenly and thoroughly, avoiding the existence of a stirring blind spot at the bottom of the reactor.

[0033] Specifically, there are multiple brackets 4, the middle part of the stirring shaft 3 is fixedly connected to the top of the stirring rod 2 and the upper half of the stirring rod 2 through the brackets 4, and the bottom end of the stirring shaft 3 is fixedly connected to the lower half of the stirring rod 2 through the brackets 4.

[0034] Working principle:

[0035] Take the distillation reactor as an example. Figure 4 As shown in the direction of the arrow, when the agitator is running, the material forms a vortex and enters from the suction port 201 of the agitator. As the agitator rotates, the material gradually rises in each stirring rod 2. When it rises to the upper part of the agitator, part of the material is thrown out from the discharge hole 202 of the stirring rod 2 by centrifugal force and splashes onto the heating wall of the reactor 1. The material contacts the upper part of the reactor and can fully utilize the heat of the upper part of the reactor for distillation, saving heating energy. The remaining material repeats the process and continues to rise and be thrown out.

[0036] The agitator of the present invention has the functions of self-absorption, spraying and mixing of materials, and has various functions. Figure 5 and Figure 6As shown, the agitator in the present invention has three-dimensional and diverse mixing modes, and has the function of self-priming and spraying while rotating and stirring. In addition to participating in the rotating mixing outside, the material also enters the stirring rod 2 for spiral ascending mixing, and then is discharged through the discharge hole 202 and falls back into the material below for aggregation. In short, in addition to the traditional horizontal vortex mixing (first curve 7), the material also has vertical circulation mixing (second curve 8) and spiral ascending mixing (third curve 9) inside the agitator. The three mixing modes go hand in hand to mix the materials evenly and thoroughly, avoiding the existence of a stirring blind spot at the bottom of the reactor.

[0037] The agitator in the present invention can suck the material from the bottom and splash it onto the upper edge of the heating surface of the reactor from the top, thereby breaking the internal balance of the material, making full use of the heating surface, and maximizing the use of heat energy. The efficiency is shortened from the original 2 hours to 1 hour, which is significantly improved, and the distillation temperature is also greatly reduced.

[0038] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
