[0001] The present invention relates to the technical field of extraction and separation, and in particular to an ultrasonic tank-type extractor and a method. Background Art

[0002] Currently, ultrasonic tank extractors are a commonly used extraction equipment, often used for the extraction of functional active ingredients. However, the extraction process of existing tank extractors is time-consuming and energy-intensive, leading to increased production costs. Summary of the Invention

[0003] In view of the above problems, the object of the present invention is to provide an ultrasonic tank extractor and method, which can effectively improve the extraction efficiency, shorten the extraction process time, and thus reduce production costs.

[0004] The technical solution adopted in the present invention is as follows:

[0005] The ultrasonic tank extractor proposed in the present invention includes an extraction tank body and a spiral compression system; the spiral compression system is arranged in the middle area inside the extraction tank body; a feeding port and a solvent feeding port are respectively provided on both sides of the top of the extraction tank body; and an extraction liquid discharge port connected to the spiral compression system is provided at the lower part of one side of the extraction tank body.

[0006] Furthermore, an ultrasonic external vibration box is provided on the outer wall of the extraction tank.

[0007] Furthermore, the spiral compression system includes a variable pitch spiral, a cylindrical screen, an ultrasonic internal vibration box, an extraction liquid collection pipe, a spiral compression system bracket, a motor drive system and a cylindrical screen bracket; the spiral compression system brackets are respectively arranged on the upper and lower sides of the extraction tank body; the cylindrical screen is bolted between the middle parts of the spiral compression system brackets on both sides; the variable pitch spiral is coaxially arranged inside the cylindrical screen; the cylindrical screen brackets are respectively fixedly connected to the upper and lower ends of the cylindrical screen; the motor drive system is arranged above the extraction tank body, and its output shaft is coaxially fixedly connected to the cylindrical screen bracket; the variable pitch spirals are solvent extrusion section I, solvent entry section I, solvent extrusion section II, solvent entry section II and solvent extrusion section III from bottom to top; wherein the pitch of the solvent extrusion section decreases and the pitch of the solvent entry section increases; the ultrasonic internal vibration box is respectively arranged outside the solvent entry section I and the solvent entry section II; the extraction liquid collection pipe is arranged on one side of the solvent extrusion section I and connected to the extraction liquid discharge outlet; the outer wall circumference of the cylindrical screen in the solvent extrusion section I area is evenly distributed with extraction mixture inlets.

[0008] Furthermore, a pneumatic slag discharge port is provided at the bottom end of the extraction tank.

[0009] Furthermore, the circumference of the ultrasonic external vibration box is evenly distributed on the outer wall of the extraction tank; the circumference of the ultrasonic internal vibration box is evenly distributed on the outer wall of the cylindrical screen.

[0010] An ultrasonic tank extraction method comprises the following steps:

[0011] The raw materials and extraction solvent enter the extraction tank through the feed port and solvent feed port respectively, and the ultrasonic external vibration box is started to perform ultrasonic extraction on the mixture of raw materials and solvent, so that the solvent is integrated into the raw material cells and the functional components in the raw material cells are dissolved;

[0012] At the same time, the motor drive system and the ultrasonic internal vibration box are started; the motor drive system drives the variable pitch screw to rotate, transporting the extraction mixture from the extraction mixture inlet to the bottom of the spiral compression system, and vertically rising along the spiral compression system; in the extraction solvent extrusion section I, the pitch of the variable pitch screw is reduced, and the extraction mixture is extruded, and the extraction liquid is discharged from the spiral compression system through the cylindrical screen, while the extraction raw material is trapped in the cylindrical screen, realizing the separation of residue and liquid;

[0013] As the variable pitch screw is conveyed, the raw materials for extraction enter the extraction solvent entry section I. The pitch of the variable pitch screw increases, the space becomes larger, and the solvent outside the spiral compression system enters the inner part through the cylindrical screen. Under the oscillation of the ultrasonic inner vibration box, the solvent and the raw materials for extraction are re-fused to dissolve the functional components in the raw material cells.

[0014] Then, as the pitch of the variable pitch helix decreases and increases again, the slag-liquid separation and fusion extraction are repeated in the solvent extrusion section II, solvent extrusion section III and solvent entry section II, thereby achieving sufficient separation and extraction of functional components in the raw material cells;

[0015] After the extraction residue is discharged from the top of the spiral compression system, it descends along the annular gap between the ultrasonic extraction tank and the spiral compression system. During this process, it is subjected to ultrasonic oscillation treatment by the ultrasonic external vibration box. Finally, it falls to the bottom of the ultrasonic extraction tank and enters the spiral compression system again. This realizes the cyclic processing operation.

[0016] When the extraction is completed, the extraction liquid outlet is connected. In the solvent extrusion section I, the extraction liquid in the extraction residue is squeezed out and discharged out of the tank along the extraction liquid collecting pipe and the extraction liquid outlet, while the extraction residue is intercepted, thereby achieving smooth discharge of the extraction liquid and minimizing the residual extraction liquid in the extraction residue. After the extraction liquid is completely discharged, the residue is discharged through the pneumatic residue discharge port.

The extractor comprises an extraction tank body 1 and a screw compression system 2; the screw compression system 2 is disposed in the middle region of the extraction tank body 1; a feeding port 101 and a solvent feed port 102 are disposed on either side of the top of the extraction tank body 1; an extract liquid discharge port 104 connected to the screw compression system 2 is disposed at the lower right side of the extraction tank body 1; an ultrasonic external vibration box 103 is disposed on the outer wall of the extraction tank body 1; and a pneumatic slag discharge port 105 is disposed at the bottom end of the extraction tank body 1.

[0027] like Figure 2 As shown, the spiral compression system includes a variable pitch spiral 201, a cylindrical screen 202, an ultrasonic internal vibration box 203, an extraction liquid collection pipe 204, a spiral compression system bracket 205, a motor drive system 206 and a cylindrical screen bracket 208; the spiral compression system bracket 205 is fixedly installed on the upper and lower sides of the interior of the extraction tank body 1; the cylindrical screen 202 is longitudinally arranged between the middle parts of the upper and lower cylindrical screen brackets 208, and its upper and lower ends are respectively bolted to the cylindrical screen brackets 208, and the mesh size of the cylindrical screen 202 can be adjusted according to the size of the extracted raw material; the variable pitch spiral 201 is coaxially arranged inside the cylindrical screen 202; the cylindrical screen bracket 208 is respectively fixedly connected to the upper and lower ends of the cylindrical screen 202; the motor drive system 206 is arranged at the extraction tank body 1 Above, its output shaft is coaxially fixedly connected with the upper and lower ends of the cylindrical screen bracket 208 in sequence, and the speed of the motor drive system 206 is adjustable to adapt to the extraction raw materials with different characteristics; the variable pitch screw 201 is solvent extrusion section I, solvent entry section I, solvent extrusion section II, solvent entry section II and solvent extrusion section III from bottom to top; wherein, the pitch of the solvent extrusion section decreases, and the pitch of the solvent entry section increases, that is, the pitch of the variable pitch screw 201 repeatedly increases and decreases; the ultrasonic internal vibration box 203 is respectively arranged on the outside of the solvent entry section I and the solvent entry section II; the extraction liquid collection pipe 204 is arranged on one side of the solvent extrusion section I and is connected to the extraction liquid discharge outlet 104; the cylindrical screen 202 is located in the solvent extrusion section I area and has four extraction mixture inlets 207 evenly distributed on the outer wall circumference.

[0028] The cylindrical screen support 208 and the screw compression system support 205 are respectively located at the same horizontal position.

[0029] The ultrasonic external vibration boxes 103 are evenly distributed on the outer wall of the extraction tank 1 in a cross-circle pattern; the ultrasonic internal vibration boxes 203 are evenly distributed on the outer wall of the cylindrical screen 202 in a cross-circle pattern.

[0030] An ultrasonic tank extraction method specifically comprises the following steps:

[0031] The raw material and the extraction solvent enter the extraction tank 1 through the feed port 101 and the solvent feed port 102 respectively. The ultrasonic external vibration box 104 is started to perform ultrasonic extraction on the raw material and solvent mixture, so that the solvent is integrated into the raw material cells and the functional components in the raw material cells are dissolved;

[0032] At the same time, the motor drive system 206 and the ultrasonic inner vibration box 203 are started; the motor drive system 206 drives the variable pitch screw 201 to rotate, and the extraction mixture is transported from the extraction mixture inlet 207 to the bottom of the spiral compression system 2, and rises vertically along the spiral compression system 2;

[0033] In the extraction solvent extrusion section I, the pitch of the variable pitch screw 201 is in a decreasing stage, and the extraction mixture is extruded. Since the mesh size of the cylindrical screen 202 is smaller than the mesh size of the raw material particles, the extract is discharged from the screw compression system 2 through the cylindrical screen 202, while the extraction raw material is trapped inside the cylindrical screen 202, achieving slag-liquid separation;

[0034] As the variable pitch screw 201 conveys the raw materials for extraction, it enters the extraction solvent entry section 1. The pitch of the variable pitch screw 201 increases, and the space becomes larger. The solvent outside the spiral compression system 2 enters the inner part through the cylindrical screen 202. Under the oscillation of the ultrasonic inner vibration box 203, the solvent and the raw materials for extraction are re-fused, and the functional components in the raw material cells are dissolved.

[0035] Then, as the pitch of the variable pitch screw 201 decreases and increases again, the residue-liquid separation and fusion extraction are repeated in the extraction solvent extrusion section II, the solvent extrusion section III, and the extraction solvent entry section II, thereby achieving sufficient separation and extraction of the functional components in the raw material cells;

[0036] After being discharged from the top of the spiral compression system 2, the extraction residue descends along the annular gap between the ultrasonic extraction tank 1 and the spiral compression system 2. During this process, it is subjected to ultrasonic vibration treatment by the ultrasonic external vibration box 103. Finally, it falls to the bottom of the ultrasonic extraction tank 1 and re-enters the spiral compression system 2. This realizes the cyclic processing operation.

[0037] After extraction is complete, the extraction liquid outlet 104 is connected. In the extraction solvent extrusion section I, the extraction liquid is squeezed out of the extraction residue and discharged out of the tank along the extraction liquid collection pipe 204 and the extraction liquid outlet 104, while the extraction residue is trapped. This ensures smooth extraction of the extraction liquid and minimizes the amount of residual extraction liquid in the extraction residue. After the extraction liquid is completely discharged, the residue can be discharged through the pneumatic residue discharge port 105.

[0038] Matters not covered in the present invention are all known technologies.
