Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine processing technology, and in particular, it is a device for filtering, concentrating and drying traditional Chinese medicine extracts. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to substances used for the prevention, treatment, and diagnosis of diseases, and possessing rehabilitation and health-preserving effects, under the guidance of TCM theory. TCM mainly originates from natural medicines and their processed products, including plant-based, animal-based, and mineral-based medicines, as well as some chemical and biological products. Medicinal herbs can be processed into TCM extracts, which include both liquid and solid forms. Liquid extracts mostly refer to TCM liquid extracts. Initially, the solvent content in TCM extracts is high, resulting in a low content of effective components. To prepare the desired pharmaceutical formulation, it is necessary to concentrate the extract to increase the concentration of effective components. Chinese patent CN221206782U discloses a TCM extract filtration, concentration, and drying device, including a drying tank. The top of the drying tank is equipped with a top cover and a feed inlet. A bottom block is installed between the inner walls of the bottom of the drying tank. Multiple crossbars are evenly fixed to the sides of the bottom block and the drying tank. The top of the bottom block rotates via a bearing. The device is equipped with a vertical rod, with a receiving dish fixedly mounted on the top of the rod. A motor is fixedly mounted on the outer side of the drying tank, and a gear is fixedly mounted on the output shaft of the motor. In this solution, starting the motor drives the gear to rotate, which engages with the receiving dish. The vertical rod is rotatably connected to the bottom block. A scraper is fixedly mounted on the bottom of the inner frame to stir the extract solution in the receiving dish. A fan blows hot air through a heating wire, and a guide tube guides the hot air, increasing the contact area with the solution and improving the efficiency of solution evaporation. This allows for concentration and drying. Existing technologies use a stirring device and a fan to heat and concentrate the extract solution. However, because the fan is positioned above the extract solution, there is a certain height difference between it and both the extract and the stirring device, making it difficult for the dissipated heat to mix fully and quickly with the solution, and the coordination with the stirring device is also relatively low.

The second sliding member 432 includes a second slider mounted on the connecting rod 43, which slides horizontally in a second groove on the wall of the empty slot. Both the support base 41 and the connecting rod 43 are perpendicular to the mounting frame 21. When the drive gear 44 rotates under the action of the drive motor, the rack drives the connecting rod 43 to move horizontally within the empty slot, thereby adjusting the position of the connecting block 431 until the connecting block... 431 is inserted into the mounting frame 21. The horizontal movement of the connecting rod 43 causes the connecting block 431 to connect to or detach from the mounting frame 21, thereby completing the docking or disassembly with the mounting frame 21. After the vibration motor 42 is turned on, the vibration is transmitted to the mounting frame 21 through the support base 41 and the connecting rod 43 and other components, so that the filtration effect of the mounting frame 21 is better during the up and down vibration. The up and down vibration of the vibration motor 42 causes the support base 41 to slide up and down in the drying tank 1 through the first sliding member 411. The up and down vibration of the mounting frame 21 enables the first sliding sleeve 31 to slide up and down on the first vertical rod 321.

[0035] The vibration support includes a second sliding sleeve 45, a second mounting bracket 46, and a second spring 462.

[0038] The implementation principle of this utility model is as follows: the filter frame is connected to the inlet 12 of the drying tank 1 through the mounting part 3, and then the driving part is turned on so that the connecting rod 43 moves horizontally until the connecting block 431 is inserted into the connecting groove 211, thus completing the docking of the vibration component 4 and the filter frame. The liquid is poured into the filter frame, and the vibration motor 42, the first fan, the second fan and the rotating motor 61 are turned on. The filtered liquid falls into the lower part of the drying tank 1. The stirring mechanism 5 stirs the liquid while transmitting the heat transmitted by the first drying component 7, so that the liquid can achieve the purpose of drying and concentration.
