Description

Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to an ultrasonic extraction device for albumin peptides. Background Art

[0002] After proteins are enzymatically hydrolyzed in the digestive tract, they are mainly absorbed in the form of oligopeptides. Albumin peptides are products of incomplete degradation of proteins, which are easily absorbed by the human body. They have the advantages of supplementing essential amino acids, maintaining plasma osmotic pressure, regulating the reproduction of beneficial intestinal flora, etc., and can better play the role of improving immune function and enhancing the body's immunity. During the extraction process of albumin peptides, ultrasonic waves can be used. Under the action of ultrasonic waves, microbubbles in the liquid will vibrate and expand, and then generate high pressure when closing, producing microjets and microshock waves. These forces can break cell walls and promote the dissolution of biological components such as albumin peptides. In the existing extraction process of albumin peptides, since albumin peptides may be extracted together with other impurities or components, the purity of the extract is not high enough, affecting the subsequent work process. Therefore, we propose an ultrasonic extraction device for albumin peptides to solve the problems mentioned above. Content of the Utility Model

[0003] In order to overcome the problem that in the existing extraction process of albumin peptides, since albumin peptides may be extracted together with other impurities or components, the purity of the extract is not high enough, affecting the subsequent work process.

[0004] The technical solution of the utility model is as follows: An ultrasonic extraction device for albumin peptides includes a filtration box body, an extraction outer box body, a water supply box and a liquid separation box body; a filtration box body for filtering impurities in the albumin peptide solution is installed at the upper end of the extraction outer box body, a water supply box for supplying cold water to cool the extraction outer box body is installed on one side of the extraction outer box body, and a liquid separation box body for separating excess water in the extracted albumin peptide solution is installed at the lower end of the extraction outer box body.

[0005] Preferably, after the albumin peptide solution is filtered, by opening the valve, the filtered solution enters the extraction inner box body through the first connecting pipe. Then, under the action of the ultrasonic vibrator, the microbubbles in the solution will vibrate and expand, and then generate high pressure when closing, producing microjets and microshock waves. These forces can break cell walls and promote the dissolution of biological components such as albumin peptides. During this process, water is poured into the water supply box through the water inlet pipe. After the action of the cooler, the temperature of the water source decreases. Then, driven by the water pump, the cold water enters the outlet pipe from the water supply box and reaches the cooling water pipe, forming a cold water circulation to cool the extraction inner box body, so as to keep the temperature inside the extraction inner box body stable.

[0006] Preferably, a rectangular cover plate is installed at the upper end of the filtering box body. An inlet pipe is installed at the upper end of the rectangular cover plate. Two groups of first sliding grooves are symmetrically opened horizontally on both sides of the inner wall of the filtering box body. A second sliding groove is opened below the position where the first sliding grooves are opened on the filtering box body. A large-hole filter plate is arranged inside the filtering box body. Two groups of first sliding blocks are symmetrically installed horizontally on both sides of the large-hole filter plate. The first sliding blocks drive the large-hole filter plate to be slidably connected with the filtering box body along the first sliding grooves. A small-hole filter plate is arranged below the large-hole filter plate. Two groups of second sliding blocks are symmetrically installed horizontally on both sides of the small-hole filter plate. The second sliding blocks drive the small-hole filter plate to be slidably connected with the filtering box body along the second sliding grooves. Drivers are installed inside the first sliding blocks and the second sliding blocks. Pour the solution of albumin peptide into the filtering box body from the inlet pipe, and then conduct preliminary impurity filtration through the large-hole filter plate and further impurity filtration through the small-hole filter plate. During this process, driven by the drivers, the first sliding blocks drive the large-hole filter plate to be slidably connected with the filtering box body along the first sliding grooves, and then driven by the drivers, the second sliding blocks drive the small-hole filter plate to be slidably connected with the filtering box body along the second sliding grooves. Thus, the large-hole filter plate and the small-hole filter plate vibrate to accelerate the filtering speed.

[0007] Preferably, first columns are installed at the upper end corners of the extraction outer box body. A first connecting pipe is installed in the middle of the upper end of the extraction outer box body. The first connecting pipe is fixedly connected with the filtering box body. A valve is arranged at the connection position between the filtering box body and the first connecting pipe. A connection hole is opened on one side of the extraction outer box body. A sealing cover plate is arranged below the extraction outer box body. A plurality of plugging columns are installed around the upper end edge of the sealing cover plate. First, drive the sealing cover plate through the plugging columns to be fixedly connected with the extraction outer box body through the plugging holes. When the filtration of the albumin peptide solution is completed, open the valve, and the filtered solution enters the extraction inner box body through the first connecting pipe. During this process, the first columns stably support the filtering box body.

[0008] Preferably, plugging holes for the plugging columns to pass through are opened below the extraction outer box body corresponding to the plugging columns. The plugging columns drive the sealing cover plate to be fixedly connected with the extraction outer box body through the plugging holes. A first round hole is opened in the middle of the sealing cover plate. An extraction inner box body is arranged in the middle of the inside of the extraction outer box body. A cooling water pipe is arranged between the extraction inner box body and the extraction outer box body. Ultrasonic vibrators are installed at the lower end corners of the extraction inner box body. A second round hole is opened in the middle of the lower part of the extraction inner box body. Then, under the action of the ultrasonic vibrators, the microbubbles in the solution will vibrate and expand, and then generate high pressure when closing, generating microjets and microshock waves. These forces can break the cell walls and promote the dissolution of biological components such as albumin peptide.

[0009] Preferably, a water inlet pipe is installed at a corner on one side of the water supply tank, a water pump is installed at a corner on one side of the water supply tank, a water outlet pipe fixedly connected to the cooling water pipe is installed in the middle of the upper end of the water supply tank, the connection hole of the water outlet pipe is fixedly connected to the extraction outer box body, and a cooler is installed inside the water supply tank. Pour the water source into the water supply tank through the water inlet pipe. Through the action of the cooler, the temperature of the water source is reduced. Then, driven by the water pump, the cold water enters the water outlet pipe from the water supply tank and reaches the cooling water pipe, forming a cold water cycle to cool the extraction inner box body, so as to keep the temperature inside the extraction inner box body stable.

[0010] Preferably, second columns are installed at the upper corners of the liquid separation box body, a second connecting pipe is installed in the middle of the upper end of the liquid separation box body, the second connecting pipe passes through the first round hole and is fixedly connected to the extraction inner box body through the second round hole. A valve is provided at the connection between the extraction inner box body and the second connecting pipe. A telescopic valve is installed on one side of the liquid separation box body, and an electromagnetic control valve is installed at the upper end of the telescopic valve. Bar-shaped grooves are symmetrically formed on both sides of the inner wall of the liquid separation box body. After the extraction is completed, by opening the valve, the solution passes through the second round hole and enters the liquid separation box body through the second connecting pipe. During this process, the second columns firmly support the extraction outer box body. Then, the solution passes through the hole separation box and the filter membrane to separate the excess water in the albumin peptide solution.

[0011] Preferably, a hole separation box is provided inside the liquid separation box body. Slide rods are installed on both sides of the hole separation box. The slide rods drive the hole separation box to be slidably connected to the liquid separation box body along the bar-shaped grooves. A filter membrane fixedly connected to the slide rods is provided below the hole separation box. A lead-out pipe is installed at a corner on one side of the liquid separation box body. A sealing round cover is sleeved outside one end of the lead-out pipe away from the liquid separation box body. After the separation is completed, through the control of the electromagnetic control valve, the telescopic valve contracts. Then, manually lift the hole separation box, and the slide rods drive the hole separation box to move out of the liquid separation box body along the bar-shaped grooves. Take out the purified albumin peptide. Then, loosen the sealing round cover, and the excess water flows out through the lead-out pipe.

[0012] The beneficial effects of the present utility model:

[0013] 1. Different from the previous situation where albumin peptides might be extracted together with other impurities or components during the extraction process, resulting in insufficient purity of the extract and affecting the subsequent work process, after the albumin peptide solution is filtered, by opening the valve, the filtered solution enters the inner extraction box through the first connecting pipe. Then, under the action of the ultrasonic vibrator, the microbubbles in the solution will vibrate and expand, and then generate high pressure when closing, producing microjets and microshock waves. These forces can break the cell walls and promote the dissolution of biological components such as albumin peptides. During this process, water is poured into the water supply tank through the water inlet pipe. After the action of the cooler, the temperature of the water source decreases. Then, driven by the water pump, the cold water enters the outlet pipe from the water supply tank and reaches the cooling water pipe, forming a cold water cycle to cool the inner extraction box and thus maintain the temperature stability inside the inner extraction box.

[0014] 2. After the extraction is completed, by opening the valve, the solution passes through the second round hole and enters the liquid separation box through the second connecting pipe. During this process, the second column firmly supports the outer extraction box. Then, the solution passes through the hole separation box and the filter membrane to separate the excess water in the albumin peptide solution. After the separation is completed, under the control of the electromagnetic control valve, the telescopic valve contracts. Then, manually lift the hole separation box, and the sliding rod drives the hole separation box to move out of the liquid separation box along the strip groove, and the purified albumin peptide is taken out. Then, loosen the sealing round cover, and the excess water flows out through the outlet pipe. Description of the Drawings

The outlet pipe 302 is fixedly connected to the connection hole 203 and the outer extraction box 2. A cooler (the model of the cooler is AH0608T) is installed inside the water supply tank 3. Second columns 401 are installed at the upper end corners of the liquid separation box 4. A second connecting pipe 402 is installed in the middle of the upper end of the liquid separation box 4. The second connecting pipe 402 passes through the first round hole 207 and is fixedly connected to the inner extraction box 209 through the second round hole 211.

A sealing round cover 410 is sleeved outside one end of the lead-out pipe 409 away from the liquid separation box 4.

[0024] When working, first drive the sealing cover plate 204 through the plug post 205 to be fixedly connected with the extraction outer box body 2 through the plug hole 206. Then pour the albumin peptide solution into the filtration box body 1 from the feed pipe 101. Next, conduct preliminary impurity filtration through the large-hole filter plate 103 and further impurity filtration through the small-hole filter plate 105. During this process, driven by the driver, the first slider 104 drives the large-hole filter plate 103 to be slidably connected with the filtration box body 1 along the first chute 107. Finally, driven by the driver, the second slider 106 drives the small-hole filter plate 105 to be slidably connected with the filtration box body 1 along the second chute 108.

[0025] When the filtration of the albumin peptide solution is completed, by opening the valve, the filtered solution enters the extraction inner box body 209 through the first connecting pipe 202.

Then manually lift the hole separation box 407, and the slide bar 406 drives the hole separation box 407 to move out of the liquid separation box body 4 along the strip groove 405 to take out the purified albumin peptide. Then loosen the sealing round cover 410, and the excess water flows out through the outlet pipe 409.

[0027] Through the above steps, after the albumin peptide solution is filtered, by opening the valve, the filtered solution enters the extraction inner box 209 through the first connecting pipe 202. Then, under the action of the ultrasonic vibrator 210, the microbubbles in the solution will vibrate and expand, and then cause high pressure when closed, generating microjets and microshock waves. These forces can break the cell walls and promote the dissolution of biological components such as albumin peptides. During this process, water is poured into the water supply tank 3 through the water inlet pipe 301. After the action of the cooler, the temperature of the water source decreases. Then, driven by the water pump 303, the cold water enters the outlet pipe 302 from the water supply tank 3 and reaches the cooling water pipe 208 to form a cold water cycle, cooling the extraction inner box 209 to keep the temperature inside the extraction inner box 209 stable.
