Description

Technical Field

[0001] This utility model belongs to the field of concentration and extraction equipment technology, specifically relating to a concentration tank for extracting berberine. Background Technology

[0002] In the extraction process of berberine, the concentration tank is one of the key pieces of equipment. Currently, in the existing technology, the concentration tank usually relies directly on the vacuum pump to regulate the pressure inside the tank when performing vacuum concentration operations.

[0003] Frequent starts and stops of the vacuum pump not only increase the energy consumption of the equipment, but also have a serious impact on the service life of the vacuum pump. As a precision device, the key components such as the seals and rotor inside the vacuum pump are subject to large pressure impacts and mechanical stress during frequent starts and stops, which can easily lead to wear and fatigue, resulting in a decrease in sealing performance and a reduction in pumping efficiency. Ultimately, this can cause the vacuum pump to fail prematurely, increasing equipment maintenance costs and the risk of production interruption.

[0004] Therefore, it is necessary to propose a utility model patent for a concentration tank for extracting berberine. Utility Model Content

[0005] The purpose of this invention is to provide a concentration tank for extracting berberine, which can reduce the frequency of vacuum pump start-up and shutdown, effectively reduce equipment energy consumption, and at the same time avoid wear and tear on key components due to frequent start-up and shutdown, thus extending the service life of the vacuum pump.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A concentration tank for extracting berberine includes a base plate, a concentration tank mounted on top of the base plate, a first pressure sensor installed inside the concentration tank, a vacuum pump mounted on top of the base plate, an air suction pipe fixed to the input end of the vacuum pump, and a buffer structure installed at the end of the air suction pipe away from the vacuum pump, the buffer structure being connected to the concentration tank.

[0008] The buffer structure includes a buffer tank installed on the top of the base plate, a second pressure sensor is installed inside the buffer tank, a delivery pipe is connected inside the buffer tank, one end of the delivery pipe away from the buffer tank extends into the concentration tank, and a solenoid valve is installed on the outside of the delivery pipe.

[0009] The end of the delivery pipe away from the buffer tank and located inside the concentration tank is equipped with a filter chamber. Filter holes are evenly arranged on the outside of the filter chamber, and multiple filter screens are arranged inside the filter chamber.

[0010] The inner wall of the filter chamber is equipped with heating wires.

[0011] An installation plate is provided inside the suction pipe. An abutment plate is provided inside the suction pipe on the side of the installation plate away from the vacuum pump. An air passage groove is provided at the center of the abutment plate. A spring is installed on the side of the installation plate near the abutment plate. An abutment ball is fixed to the end of the spring near the abutment plate, and the abutment ball extends into the air passage groove and abuts against the abutment plate.

[0012] The mounting plate has at least one through slot.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, by incorporating a buffer tank, changes the traditional method of directly regulating the pressure of the concentration tank by a vacuum pump. When reducing the air pressure inside the concentration tank, the buffer tank achieves a smooth transition and regulation of pressure, reducing the frequency of vacuum pump start-stop, effectively reducing equipment energy consumption, while avoiding wear and tear on key components due to frequent start-stop, extending the service life of the vacuum pump, reducing maintenance costs and the risk of production interruption, and ensuring the stability and continuity of the berberine extraction and concentration process.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a concentration tank for extracting berberine includes a base plate 1, a concentration tank 2 mounted on top of the base plate 1, a vacuum pump 3 mounted on top of the base plate 1, and a suction pipe 4 fixed to the input end of the vacuum pump 3. Through the suction of the suction pipe 4, the pressure inside the concentration tank 2 is reduced to -0.08 to -0.09 MPa, lowering the boiling point of the berberine extract to 40 to 60°C, thus preventing high-temperature degradation. A first pressure sensor 5 is installed inside the concentration tank 2 to monitor the pressure inside. The concentration tank 2 is equipped with an outlet... For the feed inlet and feed port, refer to the patent entitled "A Concentrating Tank for Extracting Berberine" in authorization announcement number CN209348165U. It is designed to put berberine raw material into the concentration tank 2 through the feed port, and at the same time add the liquid required for concentration and extraction. The liquid and berberine raw material enter the lower end of the concentration tank 2. Through stirring and concentration, the discharge port is opened and the berberine liquid that has been completely concentrated and extracted flows out, thus completing the extraction of berberine. The end of the suction pipe 4 away from the vacuum pump 3 is equipped with a buffer structure, which is connected to the concentration tank 2.

[0023] See attached document Figure 2 The buffer structure includes a buffer tank 6 installed on the top of the base plate 1. A second pressure sensor 12 is installed inside the buffer tank 6. The second pressure sensor 12 is set to monitor the negative pressure state inside the buffer tank 6 in real time. A delivery pipe 7 is connected inside the buffer tank 6. One end of the delivery pipe 7 away from the buffer tank 6 extends into the concentration tank 2. A solenoid valve 8 is installed on the outside of the delivery pipe 7.

[0024] When it is necessary to frequently adjust and reduce the pressure inside the concentration tank 2, the vacuum pump 3 is started, which absorbs the gas inside the buffer tank 6 through the suction pipe 4, thereby reducing the gas pressure inside the buffer tank 6 until it is lower than that inside the concentration tank 2. If it is necessary to reduce the pressure inside the concentration tank 2, the solenoid valve 8 can be opened to keep the delivery pipe 7 unobstructed. Since the pressure inside the buffer tank 6 is lower than that inside the concentration tank 2, the gas inside the concentration tank 2 will be delivered to the buffer tank 6 through the delivery pipe 7. When the first pressure sensor 5 detects that the pressure inside the concentration tank 2 is in a suitable state, the solenoid valve 8 can be closed to disconnect the buffer tank 6 from the concentration tank 2. If it is necessary to reduce the pressure inside the concentration tank 2 again, the solenoid valve 8 can be opened again. This avoids frequently opening and closing the vacuum pump 3, thus ensuring the service life of the vacuum pump 3.

[0025] See attached document Figure 3 The end of the conveying pipe 7 away from the buffer tank 6 and inside the concentration tank 2 is equipped with a filter chamber 9. Filter holes 10 are evenly arranged on the outside of the filter chamber 9, and multiple filter screens 11 are arranged inside the filter chamber 9.

[0026] When berberine is concentrated, some of the berberine raw material that is not completely crushed tends to float to the surface of the liquid, forming a layer of scum or foam. At this time, it is filtered through the filter holes 10 on the filter chamber 9 and then filtered again through the filter screen 11. According to the above structure, the inner wall of the filter chamber 9 is equipped with heating wires. By setting the heating wires, the foam can be heated and broken up.

[0027] See attached document Figure 4 An installation plate 13 is provided inside the suction pipe 4. An abutment plate 14 is provided inside the suction pipe 4 and on the side of the installation plate 13 away from the vacuum pump 3. An air passage groove 18 is provided at the center of the abutment plate 14. A spring 15 is installed on the side of the installation plate 13 near the abutment plate 14. An abutment ball 16 is fixed to one end of the spring 15 near the abutment plate 14, and the abutment ball 16 extends into the air passage groove 18 and abuts against the abutment plate 14.

[0028] When the vacuum pump 3 adsorbs gas through the suction pipe 4, at least one through groove 17 is provided in the mounting plate 13. First, the adsorption follows the through groove 17 to adsorb the abutment ball 16, causing the abutment ball 16 to compress the spring 15 and remove the obstruction to the gas passage groove 18. At this time, the gas enters the vacuum pump 3 through the gas passage groove 18 and the through groove 17 and is discharged by the vacuum pump 3. If the vacuum pump 3 is de-energized after the adsorption is completed, the gas in the suction pipe 4 will no longer flow rapidly. At this time, the spring 15 will bounce the abutment ball 16 back to the position close to the abutment plate 14 to block the gas passage groove 18, thereby avoiding the back suction effect of the buffer tank 6 under negative pressure on the vacuum pump 3, thus further ensuring the service life of the vacuum pump 3.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
