It should be noted that the aperture on the filter basket is set to 4 to 5 microns, and the aperture on the mesh bag is 0.5 to 1.0 microns. From large to small, the aperture on the filter basket is larger than the arc filter, larger than the filter sheet, larger than the filter interface, larger than the filter interface, and larger than the mesh bag.

[0024] In addition, it should be noted that the spiral heating tube 3 is an existing high-pressure heater structure. The spiral tube is usually in a spiral shape, so that the heating medium (liquid or gas) can flow continuously in the tube, and heat is conducted through the surface of the spiral tube, thereby heating the medicinal liquid in the extraction tank. The specific details will not be elaborated in this embodiment.

[0025] Further, in an embodiment, Figure 1 As shown, a sealing ring 4 that cooperates with each other is provided between the filtering device 1 and the extraction tank 2 to facilitate a sealed connection between the filtering device and the extraction tank.

At this time, the spiral heating tube is connected to the external air supply device through the connecting air pipe; then, hot air is transported into the spiral heating tube through the external air supply device to heat the medicine liquid in the device, and at the same time, the motor is started to drive the spiral stirring rod to rotate, so that the medicine liquid is fully and quickly heated; when the heating is completed, the valve on the slag outlet and the liquid outlet valve on the liquid outlet are opened, and the motor continues to work. At this time, the medicine liquid is separated from the slag and liquid by the centrifugal force generated by the high-speed rotation of the spiral stirring rod, and most of the medicine slag is discharged from the slag outlet. The remaining medicine liquid is then filtered and separated by five layers of filtering basket, arc filter, filter sheet and filter interface, and mesh bag in turn, so that a small amount of fragmented medicine slag is intercepted and falls into the filter bag, and the high-purity extract is collected into the external collector through the liquid outlet pipe to complete the extraction; after the extraction is completed, the high-pressure water spray head is opened to clean the inner wall of the extraction tank.
