Description

Technical Field

[0001] The utility model belongs to the technical field of plant extraction, in particular to a negative pressure extraction device for natural plants. Background Art

[0002] Plant extracts refer to substances extracted or processed from plants using appropriate solvents or methods, which can be used to improve health or for other purposes. They are products formed by using plants as raw materials, and according to the needs of the use of the final extracted product, through a physical and chemical extraction and separation process, directional acquisition and concentration of one or more active ingredients in the plant without changing the structure of the active ingredients. Plant extracts are widely used as raw materials or excipients for medicines, health foods, tobacco, and cosmetics. In the process of plant extraction, plants are processed by a negative pressure extraction device, which can dissolve the active ingredients in the plant in the solvent under the action of negative pressure, thereby improving the extraction efficiency. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN217067752U discloses a vacuum negative pressure structure for extracting and separating plant components, wherein a rotating rod is fixedly connected in the container, a rotating plate is rotatably sleeved on the rotating rod, a plurality of blades are fixedly connected on both sides of the rotating plate, a discharge pipe is fixedly connected on the upper left side of the container, the discharge pipe runs through the container setting, an exhaust pipe is fixedly connected on the upper side of the container, the exhaust pipe runs through the container setting, a vacuum tube is fixedly connected on the upper side of the container, the vacuum tube runs through the container setting, and the vacuum tube is located on the right side of the exhaust pipe, an opening is provided on the upper side of the container, a threaded plate is threadedly sleeved in the opening, the threaded plate runs through the opening setting, a detector is fixedly connected on the upper right side of the container, and the negative pressure extraction structure dissolves the effective components of the plant in the solvent under the action of negative pressure by evacuating the container to vacuum, but in the actual production and processing process, it is often necessary to perform negative pressure extraction operations on a large number of plants, and a large amount of external air will enter the inner side of the container during multiple feeding and discharging, and it is necessary to repeatedly evacuate to vacuum before the negative pressure extraction operation can be performed again, which increases the production cost;

[0004] 2. After the negative pressure extraction device completes the plant extraction, it is often necessary to use a filter to filter the plant residue to facilitate the collection and further processing of the solution. However, the moist plant residue often retains a certain amount of effective ingredients, resulting in a certain amount of waste. Utility Model Content

[0005] The utility model aims to provide a negative pressure extraction device for natural plants. Through a top cover, a negative pressure extraction box and an extraction bottle, the utility model solves the problem that when the negative pressure extraction device is used to extract a large number of plants, each time feeding and discharging of materials will cause air to enter the container, and it is necessary to evacuate the container again, which increases the production cost. When the plant residue is filtered after the extraction is completed, the solution remaining on the surface of the plant contains certain effective ingredients, which leads to certain waste.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a negative pressure extraction device for natural plants, comprising a top cover, a negative pressure extraction box and an extraction bottle, wherein an exhaust pipe is welded through one end of the outer peripheral surface of the negative pressure extraction box, a top cover is fixedly connected to the top of the negative pressure extraction box, a feed pipe is welded through the top of the top cover, a quantitative feeding roller is connected through the top of the feed pipe, an extraction bottle is plugged into the inner side of the negative pressure extraction box, a filter frame is plugged into the top of the extraction bottle, a pressure plate is slidably connected to one end of the filter frame, and a waste residue box is fixedly connected to one side of the extraction bottle;

[0008] By connecting the exhaust pipe and the exhaust fan, the exhaust fan can extract the air in the negative pressure extraction box, so that the plants can be extracted under negative pressure, thereby improving production efficiency. The quantitative feeding roller can transport a certain amount of plants to the inside of the extraction bottle each time, and the plants are not in contact with the external environment during feeding, so that the negative pressure extraction box is in a relative vacuum state, reducing production expenses. After the plant extraction is completed, the plant residue can be squeezed through the pressure plate, and the moisture in the plant residue can be squeezed out and transported to the waste residue box, so that the extraction device can process a large number of plants and avoid the waste of effective ingredients.

[0009] Furthermore, a hopper is welded and fixed on the top of the feed pipe, a rotating motor is inserted through one end of the feed pipe, the rotating motor is clamped on one side of the quantitative feeding roller, and both ends of the outer circumference of the quantitative feeding roller are provided with feeding grooves, and the feeding grooves are suspended on the top of the extraction bottle;

[0010] A large amount of plant raw materials can be placed in the hopper at the same time, which is convenient for continuous processing of a large amount of raw materials. When plant raw materials need to be added, the quantitative feeding roller is driven by the rotating motor to make the raw materials in the feed trough fall to the inside of the extraction bottle under the action of gravity, thereby preventing the raw materials in the hopper from falling directly into the negative pressure extraction box, which would cause the connection between the negative pressure extraction box and the external environment, and ensuring that the negative pressure extraction box is in a relative vacuum state during feeding, thereby reducing production expenses and improving production efficiency.

[0011] Furthermore, a discharge pipe is welded through the bottom of the negative pressure extraction box, a support base is clamped and fixed around the bottom of the negative pressure extraction box, and a heating plate is fixed inside the negative pressure extraction box;

[0012] The solvent can be heated by the heating plate to evaporate the solvent in the solution, thereby increasing the concentration of the effective ingredients in the solution and facilitating the extraction of plants at the most suitable extraction temperature, thereby improving processing efficiency.

[0013] Furthermore, a feeding pipe is welded through the bottom of one side of the extraction bottle, the extraction bottle is attached to the top of the heating plate, and the feeding pipe is inserted into the top of the discharge pipe;

[0014] A certain amount of solution can be discharged through the discharge pipe when it is needed, thereby improving the convenience of use.

[0015] Furthermore, a screen is inserted through the bottom of the filter frame, a first movable cylinder is inserted through one side of the pressing plate, the first movable cylinder is inserted through the extraction bottle and one side of the filter frame, a discharge plate is slidably inserted through one side of the pressing plate, a telescopic tube is inserted through the top of the discharge plate, a second movable cylinder is slidably inserted through the top of the pressing plate, the second movable cylinder is inserted through the top of the pressing plate, the discharge plate is attached to the top of the screen, and the discharge plate is located between the waste residue box and the pressing plate;

[0016] The plant residues can be filtered through the screen. After a portion of plant extraction is completed, the pressing plate is driven to move by the first movable cylinder to squeeze the plant residues, so that the moisture in the plant residues flows out through the screen. After squeezing, the discharge plate is driven to move upward by the second movable cylinder, so that the plant residues fall to the inside of the waste residue box under the action of gravity, so that the extraction bottle can process a large number of plants and is convenient for the staff to clean and process a large amount of residues.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that the negative pressure extraction structure evacuates the container to make the effective ingredients of the plant dissolve in the solvent under the action of negative pressure by arranging a top cover. However, in the actual production and processing process, it is often necessary to perform negative pressure extraction operations on a large number of plants. During multiple feeding and discharging, a large amount of outside air will enter the inside of the container, and it is necessary to repeatedly evacuate the container before the negative pressure extraction operation can be performed again, which increases the production cost. When feeding, the quantitative feeding roller can be rotated to make a quantitative amount of raw materials fall to the inside of the quantitative feeding roller, and then the raw materials are rotated to enter the inside of the negative pressure extraction box and fall into the extraction bottle under the action of gravity, thereby avoiding the air from entering the inside of the negative pressure extraction box during the feeding process, reducing production expenses and improving production efficiency.

[0019] 2. The utility model solves the problem that after the negative pressure extraction device completes the plant extraction, it is often necessary to use a filter screen to filter the plant residue to facilitate the collection and further processing of the solution, but the moist plant residue often retains a certain amount of effective ingredients, resulting in a certain amount of waste. After a plant extraction is completed, the plant residue can be squeezed by moving the pressing plate to squeeze out the liquid in the plant residue, thereby avoiding the waste of effective ingredients and moving the residue to the inside of the waste residue box, so that the inside of the filter frame can extract the plant multiple times, thereby improving the extraction efficiency.
