Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a drainage device and a traditional Chinese medicine concentration system. Background Technology

[0002] In the process of manufacturing traditional Chinese medicine, the raw liquid needs to be fed into a traditional Chinese medicine concentration system to produce concentrated liquid and evaporated water. Then, the concentrated liquid is extracted and the evaporated water is discharged. According to the law that the mass of objects in a closed container is equal, the volume of evaporated water can be calculated based on the volume and density of the raw liquid, the volume and density of the required concentrated liquid, and the density of the evaporated water. Since the concentrated liquid is extracted multiple times and the volume extracted each time is different, the volume of evaporated water discharged each time is also different.

[0003] In existing technologies, a level gauge is typically installed on the drain tank. Once the level gauge detects that the evaporated water has reached the predetermined drain level, the evaporated water is discharged. Therefore, when extracting the concentrate multiple times, the height of the level gauge needs to be manually set based on the calculated volume of evaporated water to be discharged, resulting in a low degree of automation.

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a drainage device, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A drainage device includes a drainage tank for storing evaporated water, a metering mechanism connected to the drainage tank, a monitoring mechanism for monitoring the level of evaporated water in the metering mechanism, and a controller.

[0022] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0023] To facilitate understanding of this utility model, a more complete description of it will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1 to 3 The image shows a drainage device according to a first embodiment of the present invention, including a drainage tank 10 for storing evaporated water, a metering mechanism 20 connected to the drainage tank 10, a monitoring mechanism 30 for monitoring the level of evaporated water in the metering mechanism 20, and a controller. The metering mechanism 20 includes a receiving component for containing evaporated water. The monitoring mechanism 30 includes a lifting component and a level monitor disposed on the lifting component. The level monitor is electrically connected to the controller, and the controller is electrically connected to the lifting component and is used to drive the level monitor to the monitoring point of the next drainage threshold.

[0027] Understandably, this utility model, by setting up a metering mechanism 20 connected to the discharge tank 10 and a monitoring mechanism 30 for monitoring the level of evaporated water in the metering mechanism 20, and the controller having an evaporated water calculation module, automatically calculates the volume of evaporated water to be discharged each time the traditional Chinese medicine is concentrated. Then, based on the volume of the storage tank and the volume of the receiving component, the controller can calculate the liquid level height of the evaporated water to be discharged next time in the receiving component. Then, the controller controls the lifting component to drive the liquid level monitor to the corresponding height, thereby realizing the automatic adjustment of the height of the liquid level monitor, improving the automation level of traditional Chinese medicine concentration and saving labor costs.

[0028] It should be noted that the controller is a PLC, which can automatically calculate the volume of evaporated water discharged each time based on the input raw liquid.

[0029] Specifically, in this embodiment, the monitoring mechanism 30 further includes a mounting plate 31 fixedly connected to the surface of the drain tank 10, and the lifting assembly is fixed to the mounting plate 31; the lifting assembly includes an upper support plate 33 and a lower support plate 34 fixedly connected to the mounting plate 31, a lead screw 37 rotatably connected between the upper support plate 33 and the lower support plate 34, a motor 32 fixedly connected to the upper support plate 33 and connected to the lead screw 37, and a guide rod 36 fixedly connected between the upper support plate 33 and the lower support plate 34, and the controller is electrically connected to the motor 32; the liquid level monitor includes a lifting plate 35 threadedly connected to the lead screw 37 and slidably connected to the guide rod 36, and a reed switch sensor 38 fixedly connected to the lifting plate 35, and the reed switch sensor 38 is electrically connected to the controller.

[0030] Understandably, when it is necessary to adjust the height of the liquid level monitor, the controller controls the motor 32 to rotate a calculated number of revolutions, which drives the lead screw 37 to rotate. The rotation of the lead screw 37 drives the lifting plate 35 together with the reed switch sensor 38 to rise and fall. The guide rod 36 can make the lifting plate 35 rise and fall vertically along the predetermined trajectory. Since the motor 32 has high precision, rotating the appropriate number of revolutions can accurately control the lifting height of the reed switch sensor 38.

[0031] Preferably, the motor 32 is a stepper motor 32.

[0032] Furthermore, the drainage device also includes a drainage pump, and the controller is electrically connected to the drainage pump for controlling the drainage pump to drain water.

[0033] Understandably, when the reed switch sensor 38 detects that the level of evaporated water in the containment component has reached the threshold, it sends a signal back to the controller, which can then send a signal to control the drain pump to drain the water.

[0034] Furthermore, the containment assembly includes a containment tube 21 fixedly connected to the storage tank, a magnetic float level indicator 22 fixedly connected to the containment tube 21, and a connecting tube 23 connecting the storage tank, the containment tube 21 and the magnetic float level indicator 22. The reed switch sensor 38 is used to monitor the magnetic float level indicator 22.

[0035] Understandably, by connecting the storage tank, the receiving pipe 21, and the magnetic float level indicator 22 through the connecting pipe 23, the evaporated water can be at the same level inside the three. The float in the magnetic float level indicator 22 can rise with the evaporated water. When it reaches the same height as the reed switch sensor 38, it will be detected by the reed switch sensor 38, and then the reed switch sensor 38 will send a signal to the controller, so that the controller controls the drainage pump (not shown in the figure, which belongs to the prior art) to drain water.

[0036] Specifically, the magnetic float level indicator 22 is connected to the receiving tube 21 by a fixing piece 24.

[0037] In summary, the drainage device in the above embodiments of this utility model can drive the liquid level monitor to the corresponding height by controlling the lifting component through the controller, thereby realizing the automatic adjustment of the liquid level monitor height, improving the automation level during the concentration of traditional Chinese medicine, and saving labor costs.

[0038] The second embodiment of the present invention provides a traditional Chinese medicine concentration system, which has the existing structure mentioned in the first embodiment, such as a drainage device and a concentrated liquid storage tank, which will not be described in detail here.
