Description

Technical Field

[0001] The utility model relates to the technical field of filter unloading devices, in particular to a vacuum drum filter unloading device. Background Art

[0002] The vacuum drum filter is a light-duty equipment for diatomite dehydration and recovery, and is mainly used for drying waste diatomite after filtration of beer, syrup, etc. The equipment is driven by a reducer to rotate the filter drum continuously at a uniform speed. The vacuum pressure difference formed by the vacuum pump is used to filter the material flowing through the filter tank through the distributor in the filter drum. The water in the liquid is continuously sucked into the tank for discharge or recovery; while the solid material (such as diatomite) is uniformly adsorbed on the outer surface of the drum to form a filter cake layer. When the filter cake layer reaches a certain thickness, the scraper plate in the unloading area is adjusted to feed it to the position of cutting the cake layer, and the solid material is continuously cut into the receiving trough for bagging. This cycle realizes continuous suction filtration operation, separates the discharged water from the discarded filter residue, and meets environmental protection and hygiene requirements.

[0003] After searching, a Chinese patent with a patent announcement number of CN213885246U discloses a vacuum drum filter, comprising a housing (9), a filtering part and a feeding part, wherein the filtering part comprises a filter cloth (7), and the feeding part comprises a feeding mechanism and a cooling mechanism, wherein the feeding mechanism is used to convey the material to be filtered, wherein the cooling mechanism comprises a cooling plate (6), which is located below the feeding mechanism and above the filter cloth (7) and is used to solidify the high-boiling substances in the material to be filtered. The vacuum drum filter of the utility model can prevent the high-boiling substances in the material to be filtered from passing through the filter cloth into the vacuum chamber of the drum.

[0004] However, the above design still has some shortcomings. In the above design, the distance between the filter cloth and the scraper is relatively fixed, which is difficult to adjust reasonably according to needs, which may reduce the scraping effect and result in poor use effect.
