Description

Technical Field

[0001] This utility model relates to stirring tools, specifically to a stirring device for a constant temperature water bath. Background Technology

[0002] When preparing mixed coatings that require heating and have high viscosity, it is necessary to mix resin, fillers, and additives into a constant temperature water bath, and then stir the mixture using the stirring rod of the water bath.

[0003] The existing constant temperature water bath stirring rod is composed of a stirring shaft connected to an impeller. When stirring coatings with high viscosity, laminar flow will occur due to the influence of viscosity. This laminar flow can only occur near the impeller. High viscosity coatings further away from the impeller remain stationary. The amount stirred at one time is small, and the stirring effect is poor, making it difficult to mix resins, fillers, and additives evenly.

[0004] However, given the shortcomings of existing stirring rod technology, it is necessary for researchers to develop a stirring device that is reasonably designed, simple in structure, has a strong stirring force, and can ensure that the coating is fully and evenly mixed.

[0005] In view of this, the inventors provide a stirring device for a constant temperature water bath to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stirring device for a constant temperature water bath. By setting multiple first impellers and multiple second impellers, each first impeller and second impeller has a different blade diameter, and each impeller is set at a different height on the stirring shaft, it is ensured that the impeller can stir a larger material area at one time and achieve a better stirring effect.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] This utility model provides a stirring device for a constant temperature water bath, including a constant temperature water bath, a motor mounted on a fixed shaft on one side of the constant temperature water bath, and a container for holding materials. The container is placed in the constant temperature water bath, and the output shaft of the motor is connected to a stirring mechanism that extends into the container.

[0009] The stirring mechanism includes a stirring shaft, one end of which is provided with a plurality of first impellers and a plurality of second impellers, and the other end of the stirring shaft is connected to the output shaft of a motor, and the plurality of first impellers and the plurality of second impellers are all located inside the container;

[0010] Multiple first impellers and multiple second impellers are respectively arranged at different heights on the stirring shaft.

[0011] Furthermore, the blade diameter of each of the first impellers is greater than the blade diameter of any of the second impellers.

[0012] Furthermore, the ratio of the blade diameter of each of the first impellers to the radius of the container is 0.85 to 0.95.

[0013] Furthermore, each of the first and second impellers forms a triangular structure with the stirring shaft, and each of the first and second impellers is connected to a crossbeam.

[0014] Furthermore, the crossbeam is located between the two sides of the corresponding first impeller or second impeller, and divides the first impeller or second impeller into a first part and a second part, with the area ratio of the first part and the second part being 2:1.

[0015] Furthermore, the stirring shaft, the plurality of first impellers, and the plurality of second impellers are all made of stainless steel.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0017] 1) The present invention proposes a stirring device for a constant temperature water bath, which improves the stirring part of the stirring device. By setting multiple first impellers and multiple second impellers, each first impeller and second impeller has a different blade diameter, and each impeller is set at a different height on the stirring shaft, the present invention uses blades of different heights and blade diameters to ensure that the coating at each position is fully stirred, increases the stirring force, and solves the problems of insufficient stirring volume, poor stirring effect, and difficulty in uniformly mixing resin, filler and additives.

[0018] 2) The present invention proposes a stirring device for a constant temperature water bath, wherein each first impeller and second impeller forms a triangular structure with the stirring shaft. This structure ensures that coatings with high viscosity can be stirred evenly, while also increasing the amount of coating that can be stirred. Furthermore, this impeller structure can also avoid coating waste. It has the characteristics of reasonable design, simple structure, strong stirring force, and the ability to fully and evenly mix coatings. Attached Figure Description

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] See Figure 1 This utility model embodiment provides a stirring device for a constant temperature water bath, including a constant temperature water bath 1, a motor 2 mounted on a fixed shaft (not shown in the figure) on one side of the constant temperature water bath 1, and a container 3 for holding materials. The container 3 is placed in the constant temperature water bath 1, and the output shaft of the motor 2 is connected to a stirring mechanism 4 that extends into the container 3.

[0026] The stirring mechanism 4 includes a stirring shaft 41, one end of which is provided with two first impellers 42 and two second impellers 43, and the other end of the stirring shaft 41 is connected to the output shaft of the motor 2, and the two first impellers 42 and the two second impellers 43 are all located inside the container 3;

[0027] The two first impellers 42 and the two second impellers 43 are welded to different heights on the stirring shaft 41, that is, the four impellers are at different heights.

[0028] Furthermore, the blade diameter of each first impeller 42 is greater than the blade diameter of any second impeller 43. Specifically, the blade diameter refers to the longest distance between two points on the first impeller 42 or the second impeller 43.

[0029] For high-viscosity porridge-like coatings, in order to reduce coating residue on the container wall 3, in this embodiment, the ratio of the blade diameter of each first impeller 42 to the radius of the container 3 is 0.9.

[0030] Furthermore, each first impeller 42 and each second impeller 43 forms a triangular structure with the stirring shaft 41, and each first impeller 42 and each second impeller 43 is connected to a crossbeam 44.

[0031] In this embodiment, the crossbeam 44 is located between the two sides of the corresponding first impeller 42 or second impeller 43, dividing the first impeller 42 or second impeller 43 into a first part and a second part, with an area ratio of 2:1 between the first part and the second part. This crossbeam 44 can increase the stirring range, improve the rigidity of the impeller, and make the impeller structure more robust. The triangular structure ensures that the coating inside the impeller can also be fully stirred.

[0032] In this embodiment, the stirring shaft 41, the two first impellers 42, and the two second impellers 43 are all made of stainless steel. The stainless steel material allows the constant temperature water bath 1 to be used for stirring various corrosive substances, reducing equipment maintenance costs.

[0033] During the experiment, container 3 was placed in a constant temperature water bath 1, and stirring mechanism 4 was located in container 3. Motor 1 was turned on, and motor 1 drove stirring shaft 41 to move. Stirring shaft 41 then drove first impeller 42 and second impeller 43 to move, thereby stirring the material in container 3.

[0034] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
