Description

The invention relates to filtering and can be used in the chemical, food and other sectors of the industry.

The purpose of the invention is to increase the efficiency of operation.

FIG. 1 shows a device for separating suspensions, general view, section; in fig. 2 shows section A-A in FIG. one .

The device consists of a hydrocyclone having a cylindrical housing 1, mounted on frame 2. In case 1, a tangential inlet 3 is installed, a drain patrubo

4 and a sand pipe 5. Sand pipe 5 is located opposite the endless filter belt 6 of elastic material interacting

with tensioning rollers 7, one of which is leading and connected to a rotation drive (not shown). Under the upper branch 8 of the tape 6 is installed with the possibility of vertical movement of the collector 9 of the filtrate, provided in its lower part with a nozzle 10 mounted above the nozzle 11 for draining the filtrate. On the frame 2 is also attached a pipe 12 for removal of the dried sludge. Sand pipe

5 and the nozzle 10 of the filtrate collector 9 are provided with reflectors 1J, the side walls of which are located in the cross section of the filter septum 6. The nozzle 10 is removable and attached to a pipe 1 telescopically connected to the nozzle 15 of the filtrate collector 9. The pipe 14 is attached to the rack 16, fixed

but attached to the collector 9. Seal-to the pipe 11 for removal of the filtrate

The connection of the pipe 14 and the pipe 15 is performed by a rubber ring 17. The lower branch 18 of the belt 6 is located between the nozzle 10 and the pipe 11 to drain the filtrate, and the upper branch 8 of the belt 6 is located under the Sand pipe 5.

A device for separating suspension is as follows.

The initial suspension, under pressure, QFop, is delivered through a tangential inlet pipe 3 into the cavity of the hydrocyclone body 1, where it is divided into clarified and condensed streams under the action of centrifugal force. The clarified stream is diverted through the drain pipe 4, and the condensed stream through the sand pipe 5 is directed to the upper branch 8 of the filter 55 by a discrete stream.

and can be recycled. Then the cycle repeats. Filtration 9 of the filtrate by vertical transfer is established so that the energy of the liquid jet falling from the nozzle 10 ensures complete regeneration of the tape 6.

the belt 6. The belt 6 is driven by a drive with which one of the tension rollers 7 is connected and which is leading. Upon impact of the jet stream of the condensed fraction on the upper branch 8 of the filter belt 6, the liquid phase penetrates its cells due to inertia forces, and the solid fraction remains on the surface of the belt 6. back on tape

The solid fraction, moving together with the filter belt 6, is additionally crimped with a tension roller.

7, which is installed behind the reflector 13 in the direction of movement of the tape 6. Above the nozzle 12 for draining the dehydrated sludge, the tape 6 rotates, as a result of which the dehydrated solid fraction drops it into the nozzle 12 and is discharged to its intended purpose.

The liquid phase penetrating the filter belt 6 on its upper branch 8 is collected in the filtrate collector 9 and directed through the nozzle 10 to the lower branch 18 of the belt 6 located above the nozzle 11 to drain the filtrate. Due to the impact of the filtrate flow, the filter belt 6 is regenerated. After regeneration, the liquid phase with part of the mechanical impurities enters

and can be recycled. Then the cycle repeats. The filtrate collector 9 is installed by vertical movement in such a way that the energy of the liquid jet falling from the nozzle 10 ensures complete regeneration of the belt 6.
