Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to a high-efficiency clarification extraction tank. Background Technology

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that separates mixtures by utilizing the differences in solubility of components in a solvent. It features high selectivity, low energy consumption, good separation effect, and strong adaptability, and is widely used in chemical, metallurgical, food, and petroleum refining industries.

[0003] Conventional extraction equipment can be classified into three types according to its structural characteristics: mixing-clarification extraction tanks, tower extraction, and centrifugal extraction. Among them, mixing-clarification extraction tanks have the advantages of stable separation effect, flexible process combination, and low energy consumption, and occupy a major position in chemical applications.

[0004] However, existing mixing and clarifying extraction tanks are prone to creating mixing dead zones during the mixing of light and heavy phase feed solutions. This not only causes localized phase separation but also reduces extraction efficiency, a common problem that urgently needs improvement in current mixing and clarifying extraction tanks. Patent CN119186018A, entitled "A Mixing and Clarifying Extraction Tank," incorporates both a stirring device and an ultrasonic mechanism within the mixing chamber. However, the stirring device is located inside the feed pipe, and the ultrasonic mechanism is positioned on the mixing pipe. This limitation restricts the mixing of the feed solutions within the chamber and makes it unsuitable for large-scale mixing and clarification of feed solutions. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a highly efficient clarification extraction tank.

[0006] According to the technical solution provided in the embodiments of this application, a high-efficiency clarification and extraction tank includes a primary mixing chamber, a stirring device connected to a motor, a mixing inlet A and a mixing inlet B, and a static pipe A and a static pipe B respectively provided on the inner wall of the primary mixing chamber at the outlet of mixing inlet A and mixing inlet B. Both static pipe A and static pipe B are pipes with closed upper ends and open lower ends. The primary mixing chamber is connected to an ultrasonic mixing chamber through an overflow pipe, and the ultrasonic mixing chamber is connected to a clarification chamber through an overflow plate. The lower ends of static pipe A and static pipe B are located below the overflow pipe, so that the mixture stays in the primary mixing chamber for a sufficient time and is stirred evenly by the stirring device.

[0007] Furthermore, mixing inlet A and mixing inlet B are located on the primary mixing chamber above the overflow pipe, and the lower end face of the overflow pipe is located above the overflow plate, so that the mixing material enters from the bottom of the primary mixing chamber.

[0008] Furthermore, the lower part of the ultrasonic mixing chamber is provided with a placement chamber, which contains an ultrasonic generator and an ultrasonic transducer connected by wires, and uses ultrasonic waves to mix the liquid again.

[0009] Furthermore, the clarification chamber is equipped with staggered baffles, a light phase outlet, and a heavy phase outlet to achieve the settling and separation of the mixed liquid.

[0010] Furthermore, weir plates are installed at both the light phase outlet and the heavy phase outlet.

[0011] In summary, the beneficial effects of this application are as follows: The device utilizes multiple mixing methods—stirring and ultrasonic mixing—to improve the mixing efficiency of the extraction tank. Simultaneously, a static liquid pipe is installed when the feed liquid enters the mixing chamber, allowing the feed liquid to reach the bottom of the mixing chamber, thereby extending the time the feed liquid spends within the mixing chamber, i.e., extending the stirring time, reducing the presence of mixing dead zones, and improving mixing efficiency. The device of this application can achieve large-scale continuous feed extraction. Even if mixing dead zones exist in the stirring mixing chamber, secondary mixing in the ultrasonic mixing chamber will not affect the clarification and extraction of the feed liquid in the clarification chamber, achieving efficient, rapid, and large-scale feed liquid extraction.

Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A high-efficiency clarification extraction tank, such as Figure 1 As shown, the primary mixing chamber 1 is connected to the ultrasonic mixing chamber 6 through the overflow pipe 5, and the overflow plate 7 set at the right end of the ultrasonic mixing chamber 6 is connected to the clarification chamber 8.

[0020] like Figure 2 As shown, a motor is installed on the upper surface of the primary mixing chamber 1. The motor is connected to the stirring device 2 installed inside the primary mixing chamber 1. The left end face and the front end face of the primary mixing chamber 1 are respectively provided with mixing inlet A11 and mixing inlet B12, and the right end face is provided with overflow pipe 5. The mixing inlet A11 and mixing inlet B12 are at the same height and are both higher than the overflow pipe 5. The primary mixing chamber 1 at the outlet of mixing inlet A11 and mixing inlet B12 is provided with vertically placed static liquid pipes A3 and B4. The static liquid pipes A3 and B4 are the same, both being tubular with the upper end face closed and the lower end face open. The liquid from mixing inlet A11 enters the bottom of the primary mixing chamber 1 through static liquid pipe A3, and the liquid from mixing inlet B12 enters the bottom of the primary mixing chamber 1 through static liquid pipe B4.

[0021] like Figure 1 and Figure 3 As shown, a placement chamber 61 is provided at the bottom of the ultrasonic mixing chamber 6 for placing an ultrasonic generator and an ultrasonic transducer. The transducer can emit ultrasonic waves that act on the liquid inside the ultrasonic mixing chamber 6, so that the liquid inside the ultrasonic mixing chamber 6 is mixed evenly due to the high-frequency vibration and cavitation effect of the ultrasonic waves.

[0022] The upper surface of the overflow plate 7 located at the right end of the ultrasonic mixing chamber 6 is below the upper surface of the ultrasonic mixing chamber 6, and the height of the overflow plate 7 is lower than the height of the overflow pipe 5. In the clarification chamber 8 located to the right of the overflow plate 7, staggered baffles 81 are provided, as well as light phase outlet 82 and heavy phase outlet 83 located on the right side of the clarification chamber 8. The light phase outlet 82 is located at the upper end of the clarification chamber 8, and the heavy phase outlet is located at the lower end of the clarification chamber 8. Weir plates 84 are respectively provided at the light phase outlet 82 and the heavy phase outlet 83 on the inner wall of the clarification chamber 8. The upper surface of the weir plate 84 at the light phase outlet 82 is lower than the weir plate 84 at the heavy phase outlet 83. The lower surface of the weir plate 84 at the heavy phase outlet 83 is provided with the heavy phase liquid inlet.

[0023] In use, the required mixture is introduced into the primary mixing chamber 1 through either the mixing inlet A11 or the mixing inlet B12. Since the primary mixing chamber 1 is equipped with static pipes A3 and B4, the liquid will first enter through either static pipe A3 or B4, and then flow into the primary mixing chamber 1 from below. Because the lower ends of the inlet pipes A3 and B4 are located below the overflow pipe 5, the liquid, after entering the primary mixing chamber 1, is stirred by the stirring device 2 until the liquid level in the primary mixing chamber 1 reaches the overflow pipe 5, and then overflows from the overflow pipe 5 into the ultrasonic mixing chamber. Inside the ultrasonic mixing chamber 6, because a placement chamber 61 is set at its bottom, and an ultrasonic generator and an ultrasonic transducer are installed in the placement chamber 61, the liquid entering the ultrasonic mixing chamber 6 will be subjected to ultrasonic waves and mixed again. When the liquid level in the ultrasonic mixing chamber 6 reaches above the overflow plate 7, it will overflow directly into the clarification chamber 8. The liquid in the clarification chamber 8 is a uniformly mixed liquid. After being blocked by the baffle, it slowly settles in the clarification chamber 8, realizing the separation of the original solvent phase and the extraction phase. Then it flows out through the light phase outlet 82 and the heavy phase outlet 83, thus realizing the extraction separation.

[0024] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
