Description

Technical Field

[0001] This utility model relates to the field of continuous dynamic extraction. More specifically, this utility model relates to a device for quantitative collection of extract for continuous dynamic extraction. Background Technology

[0002] Continuous dynamic extraction is a process technology that improves extraction efficiency through continuous flow and dynamic renewal of the solid-liquid interface. It is widely used in traditional Chinese medicine, chemical industry, and other fields. Compared with traditional tank extraction, the biggest advantage of continuous dynamic extraction is its continuous and high efficiency.

[0003] In continuous dynamic extraction production, materials and water are continuously added to the extraction tank at a fixed ratio. To maintain a dynamic balance of the water level in the tank, the extract liquid needs to be collected quantitatively. Traditional collection devices directly control the flow control valve opening based on data feedback from an electromagnetic flowmeter to achieve quantitative collection. However, in practical applications, the control effect has been found to be unsatisfactory. The main reason is that the high temperature of the collected extract liquid creates an air chamber within the pump body, thus affecting the overall flow rate control.

[0004] Therefore, there is a need for a device that can stably and quantitatively collect the extract during continuous dynamic extraction. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative collection device for extract in continuous dynamic extraction, so as to achieve stable quantitative collection of extract in continuous dynamic extraction.

[0006] To achieve these objectives and other advantages according to the present invention, a device for quantitative collection of extract for continuous dynamic extraction is provided, comprising:

[0016] Furthermore, in the aforementioned quantitative collection device for continuous dynamic extraction, the coolant outlet pipe and coolant inlet pipe are arranged sequentially along the flow direction of the extract in the first pipe.

[0017] Furthermore, in the aforementioned extract quantitative collection device for continuous dynamic extraction, the cooling liquid circulation assembly includes:

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0034] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] like Figure 1 As shown, an embodiment of this utility model provides a quantitative collection device for extract of continuously dynamic extraction, comprising:

[0036] An extract delivery mechanism, wherein the extract delivery mechanism is a transfer pump;

[0037] The first pipe has its outlet connected to the inlet of the extract conveying mechanism;

[0038] A cooling mechanism for cooling the first pipe;

[0039] Extract collection container;

[0040] The second pipeline has its inlet connected to the outlet of the extract conveying mechanism and its outlet connected to the extract collection tank. The second pipeline is equipped with a flow regulating mechanism and a flow detection mechanism. The flow regulating mechanism is a flow control valve and the flow detection mechanism is an electromagnetic flow meter.

[0041] In this embodiment, the inlet of the first pipe is connected to the outlet of the extractant from the continuous dynamic extraction device. After the extractant obtained from the continuous dynamic extraction device enters the first pipe, a transfer pump provides stable flow power, driving the extractant to move. As the extractant moves within the first pipe, it passes through a cooling mechanism to cool the pipe and lower its temperature to a suitable range. After passing through the transfer pump, the extractant enters the second pipe and sequentially passes through a flow control valve and an electromagnetic flow meter. The flow rate of the extractant entering the extractant collection tank in the second pipe is preset. Based on the real-time flow rate of the extractant in the second pipe obtained from the electromagnetic flow meter, the opening of the flow control valve is adjusted to ensure that the real-time flow rate of the extractant in the second pipe reaches the preset flow rate.

[0042] Preferably, in another embodiment of the present invention, the cooling mechanism includes:

[0043] A cooler has a cooling chamber inside, the first pipe passes through the cooling chamber, and the cooler is provided with a coolant inlet pipe and a coolant outlet pipe;

[0044] A coolant circulation assembly has its inlet and outlet connected to the coolant outlet pipe and coolant inlet pipe, respectively. The coolant circulation assembly includes: a cooling tower, whose outlet is connected to the coolant inlet pipe via a pipe; and a circulation pump, whose inlet is connected to the coolant outlet pipe and whose outlet is connected to the cooling tower inlet.

[0045] In this embodiment, a circulation pipeline is formed between the cooler, cooling tower, and circulation pump, and the coolant circulates in the circulation pipeline. The circulation pump, as a power source, delivers the coolant from the cooling chamber to the cooling tower for cooling. The cooled coolant then enters the cooling chamber, thereby achieving circulation of the coolant in the cooling chamber, maintaining the temperature of the coolant in the cooling chamber, and continuously cooling the extract in the first pipeline.

[0046] Furthermore, in the aforementioned extract quantitative collection device for continuous dynamic extraction, the cooler is a cooling sleeve fitted onto the first pipe.

[0047] In this embodiment, a cooling sleeve is used for cooling heat, which is easy to process and can save space; it can be installed along the first pipe.

[0048] Furthermore, in the aforementioned quantitative collection device for continuous dynamic extraction, the coolant outlet pipe and coolant inlet pipe are arranged sequentially along the flow direction of the extract in the first pipe.

[0049] In this embodiment, since the temperature of the extract in the first pipe gradually decreases as it passes through the cooler, the coolant outlet pipe and coolant inlet pipe are arranged sequentially along the flow direction of the extract in the first pipe. The flow direction of the coolant in the cooler is opposite to the flow direction of the extract in the first pipe, which can ensure the heat exchange effect between the coolant and the extract.

[0050] Preferably, as another embodiment of this utility model, in Figure 1 Based on the illustrated embodiments, as Figure 2 As shown, it also includes:

[0051] A temperature detection mechanism, installed on the first pipe, is used to measure the temperature of the extract in the first pipe after passing through the cooling mechanism. The temperature detection mechanism is a pipe thermometer.

[0052] In this embodiment, a pipe thermometer is installed on the first pipe to measure the temperature of the extract in the first pipe after passing through the cooling mechanism, thereby obtaining the cooling effect of the extract. A target temperature for the cooled extract can be preset. By obtaining the real-time temperature of the cooled extract using the pipe thermometer, the power of the circulating pump can be adjusted, thereby adjusting the flow rate of the coolant in the cooler and the cooling effect of the cooling mechanism on the extract, so that the cooled extract reaches the preset target temperature after cooling.

[0053] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
