Abstract
Description
Technical Field
[0001] This utility model relates to the field of extraction and filtration equipment technology, and in particular to a supercritical carbon dioxide extraction and filtration device. Background Technology
[0002] The unique solubility of supercritical carbon dioxide has enabled its widespread application as an extraction and purification agent to process tens of millions of tons of products in food factories. For example, supercritical carbon dioxide has been used to remove caffeine from black tea, achieving significant results in the food processing industry. However, traditional supercritical carbon dioxide extraction equipment is costly and complex in structure, making it unsuitable for use in the primary processing of food products.
[0003] However, existing technologies still have shortcomings. Existing supercritical carbon dioxide extraction equipment has a relatively complex structure, high cost, and is not convenient for rapid feeding and unloading of materials, resulting in low efficiency.
[0004] Therefore, we propose a supercritical carbon dioxide extraction and filtration device to solve this problem. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a supercritical carbon dioxide extraction and filtration device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A supercritical carbon dioxide extraction and filtration device includes a support frame; a filter tank is fixedly connected to the upper surface of the support frame; a motor is fixedly connected to the lower surface of the filter tank; an exhaust pipe is fixedly connected to one side of the lower surface of the filter tank; a mounting base is fixedly connected to the outer surface of the filter tank; a sliding groove is provided on the upper surface of the mounting base; a support ring is fixedly connected to the inner surface of the filter tank; a storage rack is slidably mounted on the upper surface of the support ring; a filter screen is fixedly connected to the inner surface of the storage rack; a connecting column is rotatably mounted on the inner bottom surface of the filter tank; an internal hexagonal groove is provided on the upper surface of the connecting column; an external hexagonal block is fixedly connected to the lower surface of the storage rack; a connecting block is slidably mounted on the inner surface of the sliding groove; a fixing screw is slidably mounted on the inner surface of the connecting block; a sealing plate is fixedly connected to the outer surface of the connecting block; an air inlet pipe is fixedly connected to one side of the upper surface of the sealing plate; a feeding pipe is fixedly connected to the other side of the upper surface of the sealing plate; a sealing cap is rotatably mounted on the outer surface of the feeding pipe; and a stirring rod is fixedly connected to the lower surface of the sealing plate.
[0007] Preferably, the external hexagonal block is slidably mounted on the inner surface of the internal hexagonal slot; the output end of the motor is fixedly connected to the lower surface of the connecting column.
[0008] Preferably, the storage rack is rotatably mounted on the inner surface of the filter tank; the storage rack is rotatably mounted on the lower surface of the sealing plate.
[0009] Preferably, the sealing plate is slidably installed on the inner surface of the filter tank; the fixing screw is rotatably installed on the inner surface of the mounting base.
[0010] Preferably, the sealing plate is fixed to the upper surface of the filter tank by fixing screws; the stirring rod is located inside the storage rack.
[0011] In this invention, a supercritical carbon dioxide extraction and filtration device is provided, comprising a support frame, a filter tank, a motor, an exhaust pipe, a connecting column, an internal hexagonal groove, a support ring, a storage rack, a filter screen, an external hexagonal block, an air inlet pipe, a feeding pipe, a sealing cap, and a stirring rod. During filtration, the storage rack is placed inside the filter tank, then the external hexagonal block is placed into the internal hexagonal groove, and then a sealing plate is installed on the upper surface of the filter tank. The sealing cap is then opened, and material is added from the feeding pipe into the storage rack. Finally, the sealing cap is closed and the material is fed into the feeding pipe. The pipe is sealed, and then the motor is started. The motor drives the connecting column to rotate, which in turn drives the storage rack to rotate via the external hexagonal block. The rotation of the storage rack causes the material to rotate, and the stirring rod stirs the material. Then, supercritical carbon dioxide is added into the filter tank through the inlet pipe, and the exhaust gas is discharged through the exhaust pipe. When the material is to be removed, the sealing plate is removed from the filter tank, and the storage rack can then be removed from the filter tank to retrieve the material. This enables rapid loading and unloading of materials, improving efficiency. In this utility model, the supercritical carbon dioxide extraction and filtration device, through the setting of the support ring, will keep the storage rack away from the inner bottom surface of the filter tank, thereby increasing the contact area between supercritical carbon dioxide and the material and improving the filtration efficiency. This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description
