Visualized cutting fluid mixing device

Abstract

This utility model relates to the field of cutting fluid mixing technology, and more particularly to a visual cutting fluid mixing device, including a mixing tank. The mixing tank has an inner cylinder inside, which is aligned with the tank's axis and open at both ends. The upper and lower ends of the inner cylinder do not contact the inner wall of the mixing tank. A motor is mounted on the mixing tank, and a spiral agitator blade located inside the inner cylinder is mounted on the motor's output shaft. Multiple rotating shafts are rotatably connected inside the mixing tank, equidistant from the inner cylinder's axis. Each rotating shaft has a stirring blade. This utility model uses the spiral agitator blades to cause the cutting fluid to rise, flowing from the inner cylinder to between the inner cylinder and the mixing tank. Simultaneously, the motor drives the spiral agitator blades to rotate, causing the stirring blades to turbulently agitate the downward-moving cutting fluid. The spiral upward and turbulent downward movements superimpose and interfere with each other, thereby improving the mixing uniformity.

Description

Technical Field

[0001] This utility model relates to the field of cutting fluid mixing technology, and in particular to a visual cutting fluid mixing device. Background Technology

[0002] The concentration of cutting fluid has a crucial impact on its performance. Excessive concentration not only increases costs but can also lead to excessive foaming and corrosion of machine tools and workpieces. Conversely, insufficient concentration fails to provide adequate lubrication, cooling, and rust prevention. In practical use, the concentration of cutting fluid can change due to water evaporation, fluid loss, and contamination during machining. Furthermore, while some cutting fluid additives may have limited effectiveness when used alone, they can produce synergistic effects when mixed with other additives, significantly improving the overall performance of the cutting fluid. Therefore, it is necessary to adjust the concentration by mixing new cutting fluid or adding water to maintain it within a suitable range.

[0003] Currently, cutting fluid mixing is achieved using traditional paddle mixers. When the paddles are working, their motion mainly revolves around the mixing shaft in a circular motion, which causes the cutting fluid to generate laminar flow in the horizontal direction. In this flow mode, vertical fluid exchange is insufficient, and the cutting fluid is difficult to fully participate in mixing in the bottom and top areas of the container. This is especially true for cutting fluids with high viscosity, which have poor fluidity, making it even more difficult to achieve uniform mixing using traditional mixing methods. Based on the above situation, it is necessary to design a visual cutting fluid mixing device to solve the above problems. Utility Model Content

[0004] This invention provides a visual cutting fluid mixing device to solve the problems in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A visual cutting fluid mixing device includes a mixing tank. Inside the mixing tank, there is an inner cylinder that coincides with the axis of the mixing tank and is open at both ends. The upper and lower ends of the inner cylinder do not contact the inner wall of the mixing tank. A motor is installed on the mixing tank. The output shaft of the motor is equipped with a spiral stirring blade located inside the inner cylinder. Multiple rotating shafts are rotatably connected inside the mixing tank and are equidistant from the circumference of the inner cylinder. Each rotating shaft is equipped with a stirring blade and a first gear. The output shaft of the motor is equipped with a second gear that meshes with the first gear.

[0007] Preferably, the spiral agitator blades adopt a variable pitch structure, and the pitch of the spiral agitator blades gradually increases from the bottom to the top of the inner cylinder.

[0008] Preferably, the output shaft of the motor is provided with a flow guide, which is located at the upper end of the inner cylinder.

[0009] Preferably, the inner cylinder is connected to the inner wall of the mixing tank by a connecting plate, the connecting plate is offset from the stirring blade, and the connecting plate has a hole for the rotating shaft to pass through.

[0010] Preferably, the rotating shaft is provided with a defoaming brush plate, and the bottom of the defoaming brush plate is serrated.

[0011] Preferably, the mixing tank is provided with a transparent observation port, and the defoaming cleaning plate is provided with a cleaning plate that fits against the inner wall of the observation port.

[0012] The beneficial effects of this utility model are as follows: the cutting fluid is raised by the spiral stirring blades and flows out from the inner cylinder to the space between the inner cylinder and the mixing tank. The motor drives the spiral stirring blades to move and the rotating shaft to rotate at the same time, so that the stirring blades turbulent the downward-moving cutting fluid. The spiral upward movement and the turbulent downward movement are superimposed and interfere with each other, thereby improving the mixing uniformity. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-5 As shown, a visualized cutting fluid mixing device includes a mixing tank 1. Inside the mixing tank 1 is an inner cylinder 2, which is axially aligned with the mixing tank 1 and open at both ends. The upper and lower ends of the inner cylinder 2 do not contact the inner wall of the mixing tank 1. A motor 3 is mounted on the mixing tank 1. A spiral agitator 31, located inside the inner cylinder 2, is mounted on the output shaft of the motor 3. When the motor 3 drives the spiral agitator 31 to rotate, the cutting fluid at the bottom of the mixing tank 1 is conveyed upwards and then flows out from the upper opening of the inner cylinder 2. The cutting fluid at the bottom continuously enters the inner cylinder 2 from the bottom opening, achieving a circulating flow. Furthermore, the cutting fluid also rotates inside the mixing tank 1. Multiple rotating shafts 4 are equidistantly arranged around the circumference of the inner cylinder 2. Agitator blades 41 are mounted on the rotating shafts 4, and a first gear 42 is mounted on the rotating shafts 4. A second gear 32 meshes with the first gear 42 on the output shaft of the motor 3. While the motor 3 drives the spiral agitator blades 31 to rotate, the second gear 32 drives the first gear 42 to rotate, thereby causing the rotating shafts 4 to drive the agitator blades 41 to rotate. This mixes and agitates the falling cutting fluid, forming a uniform mixing state of spiral ascent and turbulent descent. This allows the cutting fluid to generate a more complex three-dimensional flow in the mixing tank 1, improving the mixing uniformity.

[0022] Reference Figure 2 As shown, the spiral agitator blade 31 further adopts a variable pitch structure. The pitch of the spiral agitator blade 31 gradually increases from the bottom to the top of the inner cylinder 2. At the bottom, the smaller pitch can provide a larger thrust, effectively lifting the high-concentration, potentially high-viscosity cutting fluid at the bottom. As the cutting fluid moves upward, the pitch gradually increases, causing the thrust on the cutting fluid during its ascent to gradually decrease. This allows the cutting fluid to flow out in a more stable state when it reaches the top outlet of the inner cylinder 2, reducing the formation of foam or uneven mixing caused by excessively fast flow rate and large impact.

[0023] Reference Figure 2 As shown, the output shaft of the motor 3 is further provided with a flow guide 5, which is located at the upper end of the inner cylinder 2. The flow guide 5 limits the upward spraying of the cutting fluid from the inner cylinder 2 at the upper end of the inner cylinder 2, reducing the height distance of the cutting fluid moving upward inside the inner cylinder 2, thereby helping to accelerate the circulation efficiency of the cutting fluid in the mixing tank 1.

[0024] Reference Figure 2 as well as Figure 4As shown, the inner cylinder 2 is further connected to the inner wall of the mixing tank 1 by a connecting plate 6 for fixing the inner cylinder 2. The connecting plate 6 is offset from the stirring blade 41, and the connecting plate 6 has a hole 61 for the rotating shaft 4 to pass through, so that the stirring blade 41 will not interfere with the connecting plate 6 when it rotates with the rotating shaft 4. On the other hand, since the position of the connecting plate 6 is fixed, when the stirring blade 41 drives the cutting fluid to flow, the blocking effect of the connecting plate 6 can turbulentize the cutting fluid to a certain extent, further enhancing the mixing effect.

[0025] Reference Figure 2 As shown, further, when the cutting fluid is mixed, the generated foam is located at the top. By providing a defoaming brush 7 on the rotating shaft 4, and the bottom of the defoaming brush 7 is serrated, when the defoaming brush 7 follows the rotation of the rotating shaft 4 and passes through the foam layer, it can scrape off the foam and break it, thereby reducing the generation of foam.

[0026] Reference Figures 1-5 As shown, the mixing tank 1 is further provided with a transparent observation port 8. The mixing condition of the cutting fluid in the mixing tank 1 can be easily observed through the observation port 8, such as the amount of foam, so as to adjust the stirring rate in time. In addition, for easy observation, a cleaning plate 81 is provided on the defoaming sweeping plate 7, which is attached to the inner wall of the observation port 8. The cleaning plate 81 scrapes and cleans the inside of the observation port 8 as the rotating shaft 4 rotates, removing the cutting fluid adhering to the inner wall of the observation port 8, reducing the contamination of the inner wall of the observation port 8 caused by the adhesion of cutting fluid, and reducing the impact on the clarity of observation.
