Description

Technical Field

[0001] The utility model belongs to the field of plant extraction equipment and relates to an extraction tank equipment. Background Art

[0002] As a commonly used industrial equipment, the extraction tank plays an important role in many fields such as pharmaceutical manufacturing, food processing, and spice manufacturing. Especially in the production process of traditional Chinese medicine preparations, the extraction tank is used to extract effective components from traditional Chinese medicinal materials, such as alkaloids, glycosides, etc., and is one of the key equipment for realizing the modernization of traditional Chinese medicine production. In addition, the extraction tank is also widely used in the extraction of plant essential oils, and the aroma components in plants are extracted by physical or chemical methods for use in industries such as cosmetics and spices.

[0003] Traditional extraction processes usually include various methods such as water extraction method and alcohol extraction method. These methods often require sufficient heating and stirring of raw materials to increase the contact area between the solvent and the raw materials, thereby improving the extraction efficiency and the quality of the extract. For example, in the process of extracting plant essential oils, in order to ensure that the essential oils can be effectively extracted, generally, the method of heating while stirring is adopted to break the cell walls in plant tissues and release the essential oil components.

[0004] At present, most extraction tanks on the market are equipped with a stirring device and a heating system. Stirring is usually achieved by driving a stirring shaft with a motor. Although this method can achieve a good mixing effect to a certain extent, it increases the complexity of the equipment and the maintenance difficulty to a certain extent; heating mostly adopts the method of direct steam heating or indirect heating through an external heater. However, no matter which heating method is used, it will increase the complexity of the extraction tank and improve the maintenance difficulty. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an extraction tank equipment with a new stirring and heating design, making its structure simpler and maintenance more simple and convenient.

[0006] To solve the above technical problems, the utility model provides an extraction tank equipment, including a bracket. The upper end of the bracket is provided with an extraction tank with an open lower end. The lower end of the extraction tank is hinged with a sealing cover. An electric hydraulic rod is connected between the bracket and the sealing cover. The lower end of the sealing cover is communicated with a switching valve. The free end of the switching valve is communicated with a drainage hose. A filter residue net is arranged inside the sealing cover. The upper end of the extraction tank is provided with a feeding port, and the feeding port is hinged with a sealing cover. The upper end of the extraction tank is communicated with an output pipe and a water inlet pipe, and valves are arranged on both the output pipe and the water inlet pipe;

[0007] A circulation heating chamber is provided at the lower part outside the extraction tank. Water inlets and outlets that are respectively communicated with both ends of the circulation heating chamber are opened on the inner wall of the extraction tank. Filter meshes are arranged in both the water inlet and the water outlet. A driving motor is installed outside the circulation heating chamber. A power output shaft of the driving motor is connected with a water circulation impeller near the water inlet in the circulation heating chamber. An electric heating tube is arranged near the water outlet in the circulation heating chamber.

[0008] By adopting the above technical solution, during extraction, first add raw materials into the extraction tank from the feeding port, add water or other solvents into the extraction tank through the water inlet pipe. Subsequently, the driving motor and the electric heating tube work simultaneously, so that the water in the extraction tank enters the circulation heating chamber from the water inlet, is heated by the electric heating tube and then discharged from the water outlet, forming a rotating eddy current in the extraction tank to stir the raw materials, making the raw materials fully mixed with the materials, accelerating the extraction speed. The water vapor and essential oil are discharged and collected through the output pipe. Finally, the extract dissolved in water is discharged through the drainage hose, leaving the residue on the filter mesh. Finally, open the sealing cover to clean the residue.

[0009] The present utility model is further configured such that a plurality of spiral guide vanes distributed circumferentially are provided at the lower part of the inner wall of the extraction tank, and the spiral direction of each spiral guide vane is the same as the direction of the water outlet.

[0010] By adopting the above technical solution, the rotating water flow in the extraction tank forms an upward rotating eddy current after encountering the spiral guide vanes, which is more convenient for stirring the raw materials at the bottom.

[0011] The present utility model is further configured such that a filter cloth is provided at the upper end of the filter mesh.

[0012] The present utility model is further configured such that a pressure gauge for detecting the internal pressure is provided at the upper end of the extraction tank.

[0013] The present utility model is further configured such that the electric heating tube is in a snake shape.

[0014] Compared with the prior art, the present utility model arranges the stirring device and the heating device on the side of the extraction tank, and uses the way of circulating and disturbing the water flow to form an eddy current in the extraction tank to drive the stirring of the raw materials, which is different from the existing way of using a stirrer for stirring. And through the cooperation of the water circulation impeller and the electric heating tube, the circulating water flow is gradually heated, which can make the water in the extraction tank uniformly and rapidly heat up. And the stirring device and the heating device make the structure of the extraction tank simpler and more convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in very simplified forms and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0022] Embodiment, referring to Figures 1-5 A kind of extraction tank 2 equipment includes a support 1. The upper end of the support 1 is provided with an extraction tank 2 with an open lower end. The lower end of the extraction tank 2 is hinged with a sealing cover 3. A electro-hydraulic rod 4 is connected between the support 1 and the sealing cover 3. The opening and closing of the sealing cover 3 are driven by the expansion and contraction of the electro-hydraulic rod 4. The lower end of the sealing cover 3 is communicated with a switch valve 5. The free end of the switch valve 5 is communicated with a drainage hose 6. A filter residue net 7 is arranged inside the sealing cover 3. A filter cloth 8 is arranged above the filter residue net 7, which is used to filter out residues to prevent them from flowing into the drainage hose 6. A feeding port 9 is opened at the upper end of the extraction tank 2. The feeding port 9 is hinged with a sealing cover 10. The upper end of the extraction tank 2 is communicated with an output pipe 11 and a water inlet pipe 12. Valves 13 are arranged on both the output pipe 11 and the water inlet pipe 12. A pressure gauge 14 for detecting the internal pressure is arranged at the upper end of the extraction tank 2.

[0023] A circulating heating chamber 15 is provided at the lower part outside the extraction tank 2. The circulating heating chamber 15 is installed outside the extraction tank 2 in a detachable manner. An inlet 16 and an outlet 17 that are respectively communicated with both ends of the circulating heating chamber 15 are provided on the inner wall of the extraction tank 2. A filter screen 18 is arranged in each of the inlet 16 and the outlet 17 to prevent residues from entering the circulating heating chamber 15. A driving motor 19 is installed outside the circulating heating chamber 15. A water circulation impeller 20 is connected to the power output shaft of the driving motor 19 near the inlet 16 inside the circulating heating chamber 15. The rotation of the circulation impeller can make the liquid flow in from the inlet 16 and flow out from the outlet 17. A serpentine electric heating pipe 21 is provided near the outlet 17 inside the circulating heating chamber 15. Five spiral guide vanes 22 distributed in a circumferential manner are provided at the lower part of the inner wall of the extraction tank 2. The spiral direction of each spiral guide vane 22 is the same as the direction of the outlet 17, so that the rotating water flow in the extraction tank 2 forms an upward rotating eddy current after encountering the spiral guide vanes 22, which is more convenient for agitating the raw materials at the bottom.

[0024] Working principle: When extraction is carried out, first add the raw materials into the extraction tank 2 from the feeding port 9, add water or other solvents into the extraction tank 2 through the water inlet pipe 12, and then the driving motor 19 and the electric heating pipe 21 work simultaneously, so that the water in the extraction tank 2 enters the circulating heating chamber 15 from the inlet 16, is heated by the electric heating pipe 21 and then discharged from the outlet 17, forming a rotating eddy current in the extraction tank 2 to agitate the raw materials. And the spiral guide vanes 22 make the eddy current form an upward rotating eddy current, so that the raw materials at the bottom are quickly turned upwards, which is more helpful for agitating the raw materials, making the raw materials fully mixed with the materials, accelerating the extraction speed. The water vapor and essential oil are discharged and collected through the output pipe 11. Finally, the extract dissolved in water is discharged through the drainage hose 6, and the residues are left on the filter residue net 7. Finally, open the sealing cover 3 to clean the residues.
