SU629949A1 - Filtering element of disc-type vacuum filter - Google Patents

Description

The invention relates to the field of separation of suspensions on disk vacuum filters and can be used, in particular, in the filtration of hydrate and sludge zero alumina. Much production.

Known filter element disk vacuum fnltra, comprising a hollow metal housing, vypolpenny in the form of a sector with perforated side walls (1). An under-tube is welded to the throat sector to remove the filtrate, by which the filter element is installed in the channel opening of the hollow filter shaft. Outside, the PA sector is worn by a Balsam cloth. However, this design is not efficient, since it does not ensure the continuous removal of filtrate from the body of the filter element.

Also known is a filter element of a disk vacuum filter, comprising a housing made in the form of a hollow sector with a bottom and perforated walls, a branch pipe connected to the channels of the filter shaft, and a device for draining the filtrate from sector 2.

The disadvantages of the filter are the complexity of the construction of the sector and the low efficiency of the filtrate through the complete removal of the filtrate from various levels of the sector.

The purpose of the invention is to increase the efficiency of the filtrate by completely removing the filtrate from various levels of the sector and simplifying its design.

This is achieved by the fact that the device for removing the filtrate is made in the form of a flexible slag placed inside the sector, one end of which is connected to the branch pipe, and the other end is equipped with a tip.

The drawing shows the filter element, a general view.

The filtering element consists of a cornus 1, made in the form of a hollow sector with perforated walls 2 and a diner 3, a branch pipe 4 and a device for draining the filtrate from the sector. The device includes flexible schlang 5, placed in the sector. One end of the hose is connected to the branch pipe 4, and the other end is provided with tips 6. The branch pipe 4 is connected to the channels 7 of the filter shaft 8.

The filter element works as follows.

With the passage of the filter element in the trough with the pulp, the filtrate, non-inwardly inward of the housing 1, through the perforated casing 2 of the filter drops off at the lowest point. However near

At this point, the end of the flexible hose 5 is always located, since the tip 6, under the force of gravity, provides an uncompressed angle change1, enio il1lapn within the limits of body 1.

Through the hose 5 and the pipe 4, the filtrate is continuously withdrawn from the housing 1 into the shaft drip 7. & regardless of its position and filter trough {vertically, horizontally, obliquely). In this case, since the housing 1 remains hollow all the time, the filter element always works with a full surface.

When leaving the trough, due to the fact that in case 1 there is practically no filtrate, the precipitate immediately begins to subside.

The filter element, equipped with a device for draining the filtrate in the form of a flexible hose with a tip, improves the efficiency of the filter and simplifies its construction.
