Abstract

The invention relates to a vacuum drum filtering system. The vacuum drum filtering system comprises a waste diatomite storage tank, a mixing tank, a vacuum drum filter, a raw material temporary storage vat and a vacuum pump which are sequentially connected, wherein the vacuum drum filter comprises a bracket, a revolving drum and a filter net, and the bracket is arranged in filter tank; the revolving drum is in transmission connection with the power mechanism and is rotatably arranged on the bracket, a sewage discharging pipe connected with the filter tank is arranged on the revolving drum, anda discharging pipe connected with the raw material temporary storage vat is arranged on the revolving drum; and the filter net is arranged in the revolving drum and comprises a plurality of metal wires with wedge-shaped cross sections and a plurality of fixed ribs, the fixed ribs are annularly arrayed to form a columnar fixed frame, and the metal wires are arranged on the columnar fixed frame atcertain intervals. According to the vacuum drum filtering system, the problems that the valid filtering gaps in the surface of a filter pipe on a filtering surface of an existing drum are few, the filter flow of a unit area is low, the high-density accumulation of precipitates is easily caused due to the strong obstruction property, and therefore, vacuum drum filtering equipment is low in workingefficiency and short in service life are solved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a vacuum drum filter system. Background technique [0002] Vacuum drum filter belongs to light equipment for dehydration and recovery of diatomite, and is mainly used for drying treatment of waste diatomite after filtration of beer and syrup. The equipment is driven by the reducer to rotate the filter drum continuously and at a constant speed. Using the vacuum pressure difference formed by the vacuum pump, the material flowing through the filter tank is sucked and filtered through the distributor in the filter drum, and the water in the material liquid is continuously filtered. The solid material (such as diatomaceous earth) is evenly adsorbed on the outer surface of the drum to form a filter cake layer. When the filter cake layer reaches a certain thickness, it can be discharged by adjusting the scraper plate in the discharge area. When it reaches the position of cutting the ca...
