SU127404A1 - Continuously operating vacuum stationary horizontal filter with mixing of the processed material on the filtering surface - Google Patents

Description

The invention relates to the construction of a continuously operating vacuum filter, on whose filtering surface an unmixed material is being processed. Leaching of the cinder by the replication does not give the desired results, since it does not allow to transfer into solution those of the components of the cinder, which are contained in small quantities and can be adsorbed by the developed cinder, or can be precipitated as a result of secondary reactions following dissolution reactions.

The proposed filter allows the ozonation of the material to be transferred and the re-leaching of the leached material on the filter sump of the vacuum filter in a solvent stream.

At the same time, the process of dissolving the components takes place much faster than on conventional suction filters or on the basis of leaching with repulping.

On fng. 1 shows a vacuum stationary filter in a removable form; in fig. 2-feeder-divider in the section.

The central shaft /, mounted vertically and reinforced with noMonui metal structures 2, works from the drive -. The upper end of the shaft / is pressed into the support 4, and the lower end is installed in the socket, 5. In the upper part of the structure, a receiving bin 6 for a chlorinated candle was mounted, which goes from the bunker to the upper plate feeder 7. The plate 8 of the feeder is strengthened to the shaft cone / and is designed to automatically distribute the material in equal doses through two leakage tubes 9. Under the upper with support 4, two ring-shaped tanks are placed: external 1G, pre1; alternate for the distribution of the acid solution, and optional // for hot water.

Through chutes 9, the material is fed to the periphery of the filter) of the resting vacuum tank 12, moistened with water from the sprayed 13, and leached with a stream of the weakly acidic solution coming from the spray 14.

gal 14. The mixing and over-processing of the material is carried out with the help of transverse TpaiBepc 15 with float 16 and paddle 17, made of acid-resistant ceramic tiles.

The filtering surface of a vacuum tank, made in the form of a cylindrical thicket, is at an angle of 2 ° to the filter plane and has an olteepcTue in the middle part for unloading the processed material and transferring it to the disc feeder 18 and further to the conveyor 19. The internal volume of the vacuum tank is divided into cylindrical partitions three parts, iK each of which is connected to a vacuum resnver.

Present Invention

Continuously operating vacuum stationary horizontal filter; p with mixing of the processed material on the filtering surface, made in the form of a cylindrical thicket, characterized by the fact that, in order to combine the processes in leaching and filtration, it is equipped with a central shaft with strokes mounted on the cross-pieces of traverses and spaced centers angle to the filtering surface installed at an angle of 2-to the plane of the filter, and with the aim of unloading the treated schichty, a plate is mounted on the bottom of the central shaft ya thread.
