(54) INSTALLATION FOR CLEANING INDUSTRIAL

The invention relates to the field of filtration, namely to devices for the purification of industrial liquids using auxiliary filtering agents, and can be used to purify oils used as process lubricants for rolling non-ferrous metals.

A known installation for cleaning process lubricants, comprising a stand-alone mixer, feed tank, filter tank, including a sealed tank and placed in. filter elements in the form of cartridges or discs covered with metal mesh, a pump and a pollution tank 1.

The disadvantage of the installation is the design complexity.

A unit for cleaning liquids is also known, comprising a supply tank, a contamination tank, a separate mixer, a pump, and a filtering unit consisting of a sealed container and mesh filter elements disposed therein with an Inlet Cavity.

The disadvantage of the installation is that it is made completely sealed, which makes it difficult to diagnose

The damage of the filtering unit and its maintenance.

The aim of the invention is to facilitate the prevention, diagnosis, and maintenance of the filter unit.

This goal is achieved by the fact that in a known installation comprising a supply tank, a tank of contaminated liquid, a mixer, a pump and a filtering unit comprising a container and mesh filter elements with an inlet cavity, a mixer, and a tank are dirty; A liquid is placed in the same housing, the capacity of the filter unit is open, and the inlet cavity of the filter elements is connected to the discharge side of the pump.

It is advisable to combine the filter elements in separate sections with independent shutdown.

The drawing shows the installation, general view.

The installation includes a supply tank 1, a contamination tank 2, a filtering unit consisting of a tank 3, mesh filter elements 4 (one section is shown in the diagrams) and a pump 5.

The supply tank 1 is connected to the pollution tank 2 by a constant pipe 6 and with the possibility of connecting pipe 7 through the valve 8, and with the tank 3 of the filtering unit through the pipe 9 constantly. The soil tank 2 communicates with the container 3 through the valve 10 and with the cavity filter elements 4 - through the pump 5 and the pipe 11

The cavity of the filter elements 4 is connected to a collector 12 equipped with a valve 13. An impeller 4 is installed in the pollution tank 2, and a sump 15 is installed under the valve 13 to dry the powder.

Installation works in the following order.

During the washing-in period of the filtering powder 16, the valves 8 and 13 are closed, and the valve 10 is open. Pulp forming with Boi. the filling time of the piston when the impeller 14 rotates in the tank 2, is sucked in by the pump 5 and through the pipe. 2. After alluvium, the layer of powder 16 proceeds to filtering for which the shutter 10 is closed.

The contaminated fluid coming from the grease collector tank 2, pump 5 is fed through pipe 11 into the cavity of filter elements 4 and flows into tank 3. The liquid level in the latter rises and it flows by gravity through pipe 9 into the supply tank 1.

In the event that tank 1 is full, the clean liquid in: pipe 6 flows into tank 2. At the end of the tank, the contaminated sludge is discharged.

When the contaminated sediment is reset, the fl and 10 valves are closed, and the valve 13 is open. The fluid velocity in the cavity of the filter elements 4 increases sharply, and the pressure drops. The washed layer of contaminated powder is flushed from the internal surfaces of the filter elements into the sump 15. After the sediment has been discharged, the valve 10 is opened and tank 2 is filled, thus ensuring readiness for the period of flush.

If there is an insufficient amount of relish in tanks 2 and 3, after the sediment of contaminated nopomxli is discharged, the filling of tank 2 can also be performed by opening valve 8, i.e. discharged liquid from the supply tank 1.

The invention eliminates the need for a special mixing tank and sealing the tank of the filtration unit, reduces the number of valves and devices for controlling them, simplifies the design and maintenance of the installation. It is possible to reconstruct the system.

o filtration, operating on the principle of partial cleaning, since the capacity and occupied area of the pollution tanks and filtration unit is insignificant and for connection to the expendable

5 tanks do not need anything

significant labor costs, and the cost of additional equipment is much lower than the cost of known analogues.

The introduction of an installation for filtering technological lubricant on foil rolling mills will provide an economic effect by increasing the productivity of foil rolling mills and reducing v6paKa

on carbon formation on the surface of the foil after annealing.
