Description

Technical Field

[0001] The utility model relates to the technical field of mixed fatty acid glyceride processing equipment, in particular to a multiple filtering device. Background Art

[0002] Mixed fatty acid glycerides are a carrier for suppositories, that is, excipients. Since suppositories are a development trend in the medical field, they are in line with the basic development principle of "low toxicity and high efficiency" in medicine and the public's desire for medical care, and have developed rapidly. The matrix of hard fat suppositories is mainly composed of triglycerides of supersaturated fatty acids with longer carbon chains and different proportions of monoglycerides and diglycerides.

[0003] In the process of present mixed fatty acid glyceride production and processing, it is necessary to use corresponding multiple filter device, for filtering the impurity inside mixed fatty acid glyceride, existing multiple filter device is in the process of actual use, although good filtering effect can be achieved, but general mixed fatty acid glyceride is viscous liquid, so that it is necessary to rely on gravity to slowly filter during filtering, so that the filtration efficiency of the device is slower, therefore it is necessary to improve it.For this reason, such as application number CN202222438553.8 patent documentation disclosed a kind of multiple filter device, including base, the top of the base is fixedly connected with the first barrel, and the both sides of the base top are fixedly installed with the support frame positioned at the outside of the first barrel. The utility model provides a threaded rod and a disc. An operator passes the mixed fatty acid glyceride to be filtered into the interior of the second barrel through a connecting pipe, and then closes the valve. Due to the operation of the drive motor, the threaded rod rotates and the disc moves downward. At this time, the pressure in the space below the disc increases, so that the greater pressure pushes the mixed fatty acid glyceride inside the second barrel to move downward, so that the mixed fatty acid glyceride is quickly filtered out of internal impurities by the first filter plate, the second filter plate and the third filter plate, thereby improving the filtration efficiency of the device.

[0004] However, the above technical solution still has some technical problems that need to be improved. For example, after filtration, there will be sticky mixed fatty acid glycerides on the cylinder wall that need to be cleaned. At this time, the above technical solution uses a split cylinder plus a movable scraper between the cylinders, which will make the overall sealing insufficient. At the same time, the overall structure needs to support the split cylinder and requires an additional motor to drive the scraper, which makes the cost of the entire device too high. In actual use, some mixed fatty acid glycerides will stick to the scraper, resulting in the operator still needing to clean the scraper in the end. Utility Model Content

[0040] Specific working process and working principle:

[0041] First, the operator passes the mixed fatty acid glyceride to be filtered into the first barrel 110, and then starts the drive motor 310, which will cause the threaded rod 320 to rotate, so that the disc 330 will move downward along the thread on the surface of the threaded rod 320. At this time, the pressure in the space below the bump 340 will increase, thereby pushing the mixed fatty acid glyceride inside the first barrel 110 to move downward by pressure, and then the mixed fatty acid glyceride is quickly filtered out of internal impurities by the multi-layer filter plate 210. The filtered mixed fatty acid glyceride has the following flow process: during the filtering process, the mixed fatty acid glyceride filtered by the multi-layer filter plate 210 is more and has a larger mass. It falls directly due to gravity. When the filtering process is nearing the end, the mixed fatty acid glyceride filtered by the multi-layer filter plate 210 gradually decreases, and the mass also gradually decreases. Due to the existence of surface tension, the mixed fatty acid glyceride filtered by the multi-layer filter plate 210 Fatty acid glycerides will diffuse at the bottom of the multi-layer filter plate 210. At this time, the presence of the partition ring 230 will cause the mixed fatty acid glycerides near the second cylinder 120 to slowly gather to the bottom of the partition ring 230 instead of sticking to the second cylinder 120. At the same time, since the surface of the bottom of the partition ring 230 gradually converges into a point, more mixed fatty acid glycerides gather, and thus fall under the action of gravity; finally, the remaining mixed fatty acid glycerides will adhere to the inner side of the partition ring 230 and the bottom of the multi-layer filter plate 210 under the action of surface tension and solidify after the temperature drops, and the overall residue is less; at this time, by turning on the heating device 410 and controlling the temperature of the heating device 410 through the temperature sensor 420, the temperature in the second cylinder 120 and even the entire filter cylinder is suitable, so that the remaining mixed fatty acid glycerides will not solidify but remain in a fluid state, and continue to fall under the action of gravity, effectively reducing the residue.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
