Description

Technical Field

[0001] The utility model relates to the technical field of material separation, in particular to a slag-liquid separation device at a discharge port. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles, and is widely used in various fields. For example, when preparing chlorogenic acid, it is necessary to grind green coffee beans, honeysuckle, eucommia and other raw materials, perform enzymatic hydrolysis, extraction, preliminary separation, membrane ultrafiltration and other steps. The preliminary separation is to separate the preliminary chlorogenic acid extract obtained from the green coffee beans and other raw material waste residues. Therefore, the centrifuge is also one of the equipment needed in the production process of chlorogenic acid. There are many types of centrifuges, among which the bottom discharge centrifuge is a commonly used one. The bottom discharge centrifuge is usually provided with a lower slag discharge port at the bottom of the drum, and a discharge port connected to the lower slag discharge port is provided on the machine base. The raw material waste residue produced after the chlorogenic acid extraction can be scraped to the lower slag discharge port and the discharge port by the scraper device in the centrifuge, and then discharged out of the centrifuge. However, since the lower slag discharge port is open, when the mixture of chlorogenic acid extract and raw material waste slag is added into the drum, the mixture will enter the discharge port from the lower slag discharge port, and the chlorogenic acid extract in this part of the mixture cannot be separated.

[0003] A Chinese patent with announcement number CN217699609U discloses a vertical centrifuge with a cleaning structure, which relates to the field of material separation technology, and includes a base, an outer barrel assembly arranged on the base, a drum rotatably mounted inside the outer barrel assembly, a driving assembly mounted on the base and connected to the drum for driving the drum to rotate, a cover assembly connected to the driving assembly, and a telescopic assembly connected to the cover assembly; a discharge port is arranged at the bottom of the drum, and the telescopic assembly can control the cover assembly to move up and down so that the cover assembly can open and close the discharge port.

[0004] The vertical centrifuge with a cleaning structure described in the above patent, when in use, the cylinder extends, so that the sealing cover closes the discharge port, and the mixture of chlorogenic acid extract and raw material waste residue is added to the drum from the feeding pipe, and the mixture of chlorogenic acid extract and raw material waste residue stays in the drum. Then the driving motor drives the drum to rotate, and the chlorogenic acid extract in the mixture is thrown out of the drum by centrifugal force, and the chlorogenic acid extract is collected through the discharge port for subsequent membrane ultrafiltration process. After the centrifugal treatment is completed, the driving motor stops working, and the scraper device starts working to scrape the raw material waste residue on the inner wall of the drum onto the cover and the sealing cover. Thereafter, the cylinder contracts, driving the sealing cover to move up, and the discharge port is opened. Since the cover and the sealing cover are both inclined side walls, the raw material waste residue slides off the cover and the sealing cover, and is discharged from the discharge port and the discharge hopper. However, it is difficult for the extract to be discharged and separated cleanly at the bottom of the outer cylinder only by the discharge port, which reduces the slag-liquid separation effect.
