Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment accessories, specifically to an acoustic resonance batch mixing tank. Background Technology

[0002] Acoustic resonance mixers, as a novel impeller-free mixing method, generate high-intensity vibrations through the principle of mechanical resonance, thereby producing low-frequency, high-intensity sound waves in the mixture to ensure uniform mixing. They offer unique advantages such as environmental friendliness, high efficiency, and safety. Acoustic resonance mixers are suitable for dispersing and mixing ultrafine and high-viscosity materials and are increasingly being applied in the pharmaceutical, food, biological, cosmetic, and energetic materials chemical industries.

[0003] Currently, acoustic resonance mixing equipment is categorized into desktop and industrial grades based on processing capacity, allowing users to purchase the appropriate equipment according to their specific needs. Acoustic resonance mixing equipment is equipped with containers that can only mix a single formula at a time. This results in wasted container space when mixing small quantities of ingredients and also limits the efficiency of simultaneous mixing of multiple formulas, thus hindering the improvement of acoustic resonance mixing experimental efficiency.

[0017] Example 1:

[0018] See Figure 1 A batch mixing tank with acoustic resonance includes a water bath tank body 1 and a top cover 3. The water bath tank body 1 is provided with a mixing cup holder 9. The middle part of the mixing cup holder 9 is provided with a support tube seat 91. Multiple cup holders 92 are provided around the support tube seat 91. A sealed water bath cavity 2 is formed between the mixing cup holder 9 and the water bath tank body 1. The side wall of the water bath tank body 1 is provided with a water inlet 6 and a water outlet 5. A temperature sensor (not shown in the figure) is provided in the support tube seat 91. The temperature sensor is used to monitor the temperature inside the water bath tank body 1 in real time. The top cover 3 is fixedly connected to the water bath tank body 1 by a clamp 8.

[0019] See Figure 2 In this embodiment, the upper part of the mixing cup holder 9 is a disc, and a support tube seat 91 extends downward from the center of the disc. The support tube seat 91 is in the shape of a test tube, open at the top and closed at the bottom. Multiple cup holders 92 of different volumes are arranged circumferentially around the support tube seat 91 on the disc, and the bottom of the cup holders 92 can extend downward beyond the bottom surface of the disc. The mixing cup holder 9 is fixedly placed inside the water bath tank 1 by the support tube seat 91. The size of the cup holders 92 is adapted to different specifications of disposable mixing cups, and the appropriate cup holder is selected according to the amount of medicine to be mixed. The number and volume of the cup holders 92 can be freely selected.

[0020] See Figure 1In this embodiment, the diameter of the opening of the water bath tank 1 is smaller than the diameter of the inside of the tank. The diameter of the opening of the water bath tank 1 is the same as the diameter of the disc on the upper part of the mixing cup holder 9, and the upper surface of the disc is flush with the opening of the tank. The water bath tank 1 and the mixing cup holder 9 are processed separately, and then assembled and welded into one piece.

[0021] See Figure 3 In this embodiment, the side wall of the water bath tank 1 is provided with an inlet 6 and an outlet 5. The inlet 6 and the outlet 5 are connected to the water bath cavity 2 inside the water bath tank 1. The height of the inlet 6 is lower than the height of the outlet 5.

[0022] See Figure 4 In this embodiment, the inner side of the top cover 3 is provided with multiple mixing cup stabilizing grooves 31, and the multiple mixing cup stabilizing grooves 31 correspond one-to-one with multiple cup holders 92. After the top cover 3 is sealed and connected to the water bath tank 1, the space between the mixing cup stabilizing groove 31 and the cup holder 92 accommodates a disposable mixing cup. The disposable mixing cup consists of a cup body and a cup lid. The cup body is inserted into the cup holder 92, and the cup lid is embedded in the mixing cup stabilizing groove 31 to prevent the disposable mixing cup from shaking during the acoustic resonance mixing process, thus affecting the mixing effect and preventing material splashing.

[0023] See Figure 1 In this embodiment, a sealing ring 7 is provided between the lower edge of the top cover 3 and the upper edge of the water bath tank 1. The lower edge of the top cover 3 is provided with an annular groove, and the sealing ring 7 is installed in the annular groove. When the top cover 3 and the water bath tank 1 are sealed together, the sealing ring 7 prevents friction and collision between the top cover 3 and the water bath tank 1 during the acoustic resonance mixing process, reduces abnormal noise, avoids sparks, and improves safety in use.

[0024] See Figure 1 In this embodiment, the top cover 3 is provided with a sensor interface 4, which is connected to the inner cavity of the support tube seat 91, and the temperature sensor is fixed on the sensor interface 4.

[0025] The mixing container is made of stainless steel, making it resistant to rust and damage. The disposable mixing cups are made of plastic, including PTFE and PMMA.

[0026] This invention transforms the single-formulation kilogram-level mixing method into a multi-formulation hundred-gram-level mixing method, improving the efficiency of small-volume propellant slurry preparation. Furthermore, the mixing tank is used with disposable mixing cups, eliminating the need for tank cleaning after use and facilitating material loading and unloading, further enhancing the production efficiency of multi-formulation propellant mixing.

[0027] This embodiment is based on a certain butylated hydroxyl propellant formulation, and different formulations of propellant slurries are prepared to verify the mixing uniformity.

[0028] First, fix the water bath tank to the acoustic resonance platform and install the temperature sensor (probe) on the top cover.

[0029] Weigh out 30 grams and 60 grams of each propellant component separately and pour them into disposable mixing cups. Select the appropriate size disposable mixing cup based on the required dosage.

[0030] Place all disposable mixing cups in the cup holder, and seal the top cover to the water bath tank. Turn on the water bath heating device and set the temperature to 50 degrees Celsius. Connect the water bath heating device to the inlet and outlet to circulate hot water into the water bath chamber.

[0031] Once the temperature reaches the preset temperature, turn on the acoustic resonance mixing device and mix for 5 minutes at an acceleration of 50g.

[0032] Open the top lid, stir the material briefly, mix the remaining material on the cup wall into the syrup, close the top lid and continue mixing at 50g acceleration for 5 minutes.

[0033] After mixing, the surface of the slurry is smooth, all materials are evenly dispersed, and the mixing effect is good.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of this utility model, and should all be covered within the scope of the claims of this utility model.
