Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a stirring tank. Background Art

[0002] Stirring refers to an operation in which two or more materials are dispersed between each other by means of flow. Its function is to achieve uniform mixing of substances, promote dissolution and gas absorption, and enhance physical and chemical changes such as heat exchange. For non-Newtonian fluids, the viscosity of the fluid decreases with the increase of stirring. The viscosity is the highest when it is still, and stratification will occur. If the stirring is not sufficient during the processing, the height of the stratification will be different after the finished product is left to stand, affecting the cost perception. For this reason, it is necessary to stabilize the viscosity of the fluid at a lower value during the processing and avoid stratification. After the processing is completed, the viscosity increases to form a uniform and consistent stratification. However, the common stirring tanks currently have a large stirring dead zone, which makes it difficult to meet the above stirring requirements. Utility Model Content

[0029] Combine the following Figure 1-Figure 3 The invention discloses a stirring tank.

[0030] The utility model embodiment provides a stirring tank, such as Figure 1 As shown, it includes a tank body 10, a stirring shaft 20 and a stirring paddle 30. The stirring shaft 20 is installed in the tank body 10. The stirring paddle 30 is installed at the end of the stirring shaft 20. Figure 1 As shown, the stirring shaft 20 is arranged to be inclined relative to the horizontal plane. Figure 2 As shown, the vertical plane where the stirring shaft 20 is located is eccentrically arranged relative to the central axis of the tank body 10 .

[0031] The stirring shaft 20 is installed in the tank body 10 in an inclined state, and the stirring paddle 30 is installed at the end of the stirring shaft 20 and can rotate, driving the fluid in the tank body 10 to achieve uniform mixing. Among them, the stirring paddle 30 can be rotatably installed at the bottom end of the stirring shaft 20, and the top of the stirring shaft 20 is fixedly connected to the tank body 10. The stirring shaft 20 is provided to provide an installation position for the stirring paddle 30. Optionally, the rotation axis of the stirring paddle 30 coincides with the central axis of the stirring shaft 20 to ensure that the stirring shaft 20 is subjected to balanced force and improve the installation stability of the stirring paddle 30.

[0032] It should be noted that the vertical plane where the stirring shaft 20 is located refers to the vertical plane where the central axis of the stirring shaft 20 is located, and the plane is parallel to the central axis of the tank body 10 .

[0033] Specifically, Figure 1 In the perspective shown, the central axis of the stirring shaft 20 forms an acute angle with the horizontal plane, so that the stirring shaft 20 is tilted in the tank body 10. Figure 2 In the perspective shown, the stirring shaft 20 extends vertically, and there is a gap between the vertical plane where the stirring shaft 20 is located and the central axis of the tank body 10, so that the stirring shaft 20 is eccentrically arranged. Therefore, when the stirring paddle 30 rotates to stir the fluid in the tank body 10, the flow dead zone in the tank body 10 can be effectively reduced, and the flow dead zone is controlled to be less than 0.5%, which effectively improves the uniformity of fluid stirring.

[0034] Taking chocolate milk processing as an example, chocolate milk is a pseudo-plastic fluid in a non-Newtonian fluid. If the stirring is uneven during the stirring process, the stratification line formed by the precipitation after filling will be at different heights, which will bring a bad experience to the user. After using the stirring tank provided by the utility model, the stirring of the stirring paddle 30 will decrease as the stirring degree is strengthened, and the viscosity is the largest when it is stationary. Therefore, it is necessary to ensure that the product has a stable and low viscosity during the processing process to avoid stratification, and the viscosity increases after the processing is completed to form a uniform and consistent stratification.

[0035] like Figure 3As shown, a drive motor 60 is fixedly installed on the outside of the tank body 10, and the drive motor 60 is transmission-connected to the stirring shaft 20. It is understandable that the length of the stirring shaft 20 varies according to the specifications of the tank body 10 and the filling amount of the fluid in the tank body 10. For example, if the injection amount of the fluid in the tank body 10 is less than half of the capacity of the tank body 10, the stirring shaft 20 can be designed to be relatively long. For another example, if the injection amount of the fluid in the tank body 10 exceeds half of the capacity of the tank body 10, the stirring shaft 20 can be appropriately shortened. It should be noted that the amount of fluid injected into the tank body 10 needs to submerge the stirring paddle 30 to ensure that the stirring paddle 30 can run smoothly.

[0036] The stirring tank provided by the embodiment of the utility model has a stirring paddle 30 installed at the end of the stirring shaft 20, wherein the stirring shaft 20 is inclined relative to the horizontal plane and is eccentrically arranged relative to the central axis of the tank body 10, so that the stirring shaft 20 is arranged in an inclined state in the tank body 10. The stirring paddle 30 can fully stir the fluid in the tank body 10 during stirring, effectively reducing the stirring dead zone and improving the stirring effect.

[0037] Optionally, the normal angle between the central axis of the stirring shaft 20 and the horizontal plane is 15° to 45°.

[0038] The normal direction of the horizontal plane refers to the vertical direction, that is, the central axis of the tank body 10. Figure 1 As shown, the angle formed between the central axis of the stirring shaft 20 and the normal of the horizontal plane is α, which is 15°, 20°, 45° or any angle between 15° and 45°. Compared with the traditional stirring shaft 20 vertically arranged in the tank body 10, the flow field generated by the rotation of the inclined stirring shaft 20 can effectively improve the mixing effect of the fluid inside the tank body 10.

[0039] Optional, such as Figure 2 As shown, there is a first distance H between the vertical plane where the stirring shaft 20 is located and the central axis of the tank body 10. The first distance H is 15% to 25% of the diameter R of the tank body 10.

[0040] The stirring shaft 20 is not arranged on the central symmetric plane of the tank body 10, but is arranged to one side of the tank body 10. Through the fluid stirring simulation test, it can be known that the eccentrically arranged stirring shaft 20 is arranged in an inclined manner, which can effectively reduce the flow dead zone area in the tank body 10, reduce the amount of unstirred fluid, and improve the stirring effect. For example, the first spacing is 15% of the diameter of the tank body 10, and for another example, the first spacing H is 20% or 25% of the diameter R of the tank body 10. Of course, the first spacing H can also be the product of the diameter R of the tank body 10 and any value between 15% and 25%.

[0041] The tank body 10 includes a columnar section and frustum sections disposed at both ends of the columnar section. The diameter of the tank body 10 refers to the diameter of the columnar section in the tank body 10 .

[0042] like Figure 3 As shown, the tank body 10 includes an inner tank 11 and an outer tank 12, and the outer tank 12 is located outside the inner tank 11, and a heat-insulating interlayer is formed between the inner tank 11 and the outer tank 12. The inner tank 11 is provided with a first through hole 13, and the outer tank 12 is provided with a second through hole 14. In order to facilitate the installation of the stirring shaft 20, the stirring tank also includes a connecting cone 40. The connecting cone 40 is fixed at the second through hole 14, and the end of the stirring shaft 20 away from the stirring paddle 30 passes through the first through hole 13 and is connected to the connecting cone 40. The driving motor 60 is connected to the stirring shaft 20 through the connecting cone 40.

[0043] The connecting cone 40 partially extends through the second through hole 14 into the outer tank 12 to provide a position for installing the stirring shaft 20. It can be understood that the connecting cone 40 is sealed and connected to the outer tank 12 of the tank body 10. For example, one end of the connecting cone 40 is welded and fixed in the second through hole 14.

[0044] like Figure 3 As shown, the outer tank 12 is provided with a protruding connection platform 15 , and the connection cone 40 is fixed to the connection platform 15 .

[0045] The installation position of the connecting cone 40 is determined according to the size of the tank body 10. In one embodiment, the size of the tank body 10 is relatively large, such as Figure 1 As shown, the connecting cone 40 is installed in the cylindrical section of the tank body 10. In another embodiment, the size of the tank body 10 is smaller, such as Figure 3 As shown, the connecting cone 40 can be installed on the frustum section of the tank body 10 .

[0046] Based on the above embodiment, a reinforcing ring 50 is installed at the second through hole 14 .

[0047] The reinforcing ring 50 is used to partially reinforce the second through hole 14 of the tank body 10, enhance the strength of the tank body 10, and prevent the tank body 10 from being weakened due to the opening. Specifically, the reinforcing ring 50 is welded and fixed to the outer tank 12. The material of the reinforcing ring 50 is the same as that of the tank body 10.

[0048] The stirring paddle 30 includes a plurality of blades, and the plurality of blades are evenly distributed around the circumference of the stirring shaft 20. Optionally, the number of the blades is three or four.

[0049] Optionally, the tank body 10 is provided with a liquid inlet and a liquid outlet, and the liquid level of the liquid inlet is lower than the liquid level of the liquid outlet. For example, the liquid inlet is set at a low liquid level at the bottom of the tank body 10, and the liquid outlet is set at a high liquid level at the bottom of the tank body 10, as long as the liquid inlet is located at a lower position than the liquid outlet. The fluid flowing in from the liquid inlet can be stirred by the stirring paddle 30 before flowing out, avoiding the fluid flowing out directly after entering, and ensuring the consistency of the performance of the fluid flowing out of the tank body 10.

[0050] Since chocolate milk is a pseudo-plastic fluid among non-Newtonian fluids, its viscosity will decrease as the degree of stirring increases during the stirring process, and its viscosity is the highest when it is still. Therefore, it is necessary to ensure that the product is stable and has a low viscosity during the processing to avoid stratification. To this end, the stirring tank provided by the utility model also includes a controller, which is electrically connected to the drive motor 60, and the controller controls the stirring paddle 30 to stir intermittently.

[0051] The controller controls the stirring shaft 20 to stir for a preset time interval, which is arranged outside the tank body 10, so that the user can set the preset time interval and the preset time. For example, the controller controls the stirring paddle 30 to stir for 2 minutes at intervals of 10 minutes, and controls the viscosity of the chocolate milk to be stable within the preset range by intermittent stirring. For another example, the controller controls the stirring paddle 30 to stir for 4 minutes at intervals of 20 minutes. Of course, the preset time interval can be set to any value between 2 minutes and 4 minutes, and the preset time is any value between 10 minutes and 20 minutes.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
