SU1340798A1 - Installation for filtering a liquid - Google Patents

Abstract

The invention relates to fluid filtration plants used in metalworking and allows for improved operational properties. The installation contains a filter 1, a pump station 2, a tank 3, a device for controlling the operation of the installation, pipelines 13, 15, 18, 20, 24 with shut-off valves 14, 16, 19, 22, 23 connecting pipelines 13, 15, 18, 20 , 24 between themselves and the consumer and drain trays. Liquid from tank 3 pumping station. 2, pressure pipe 20 is supplied to consumers. During regeneration, the liquid from the tank 3 through pipelines 13 and 15 enters the chamber 6 of the filtrate, shut-off valves 14 and 16 are open. During filtration, the valve 14 is closed and in the chamber 5 of the source liquid the level that is minimally necessary for the operation of the pump station 2 is maintained, and therefore the dehydrated sludge is carried to the sediment discharge zone. 1 il.

The drawing shows the scheme of the Liltratny liquid installation and shows the position of the valves at the exact moment of the installation operation when filling the pressure head and the slide; pipelines).

The installation consists of filter 1, tank 3 and VCT, with smallpox, becoming roist in the control of the operation of the equipment — 1 anoHKi; (not shown in the drawing),) Gr I mr.-dst is a reservoir, divided by a filter partition 4 hours, the upper chamber 5 of the cold liquid and the lower chamber 6 of the filtrate, the chamber 5 of the original liquid wasps was found. The device is equipped with 7 d; 7 nd water and liquid distribution and a scraper conveyor 8 with a drive 9. The lower branch of the transdorter 8 is in contact with the filtering line (the city, A, No. 1, can be separated (. filtering: - Material 10. unwinding from a roll P. ..

Shut-off valve 14 with the entrance of the pump station 2 , while the output of the pumping station is connected to the chamber 6 of the filtrate by pipe 15, which is equipped with a shut-off valve n 16 and valve 17, designed to regulate the flow rate of the liquid that provides support in the filtrate chamber 6 when the conveyor 8 is moved. The input of the pump stand 2 and the filtrate chamber 6 are connected by a pipe 18, on which a shut-off valve 19 is installed. From the exit of the pump station 2 to the consumers conducts pressure pipe 20, to which pipe 21 with a shut-off valve 22 installed on it, tank 3 is connected. On the section of pressure pipe 20 between the tank 3 and consumers, a shut-off valve 23 is installed.

The fluid filtradition laboratory works in a pedagogical way.

At the beginning) H1 | 1Y moment p, 1 installation time, tank 3 is filled to h rop V l overflow per (l filter. When the installation is switched off, valves 14 and 23 are opened, K. ap. 1.1 16, 19 and 22 are closed. 111.1 tons. Liquid from tank 3 pivot stand1 and 2 across the ncjpHONfy pipeline 20 is fed by consumers to the cutting tool, and then via the drain trays 24 the contaminated liquid returns to phi 1 and through the distribution device 7 enters the chamber 5 of the original liquid. Upon reaching the level, “in chamber 5, which is necessary for operation of the pumping station 2, valve 19 is opened, The valve is accessed ;: 14, the pump is fed by the vacuum filg. of the tradition, and the decontaminated fluid is supplied by the pumping station 2 from filter 1 to the machines through pipeline 20.

 B The liquid level in the tank 3 during the filling of the system of pressure pipelines 20 and drain trays 24 is reduced to a level that provides the need (liquid volume;

Upon reaching 6 fil1 in 1samer, a given vacuum pressure is given

c sigcha.l on filter regeneration, valve 19 is closed, valves 14 and 16 are opened, i.e. the filtrate chamber 6 and the pumping station 2 inlet are broken up, and the tank 3 through the valve 14, the pine station 2 is needed and the valve 16 communicates with the filtrate chamber 6. During regeneration, the liquid from the tank 3 is delivered by the pumping station to 2 consumers, and a part of it to the 1S pipeline

(JU) enters the filtrate chamber 6 and creates a liquid doodor in it, thanks to which a layer of sludge above the filter screen 4 seems to float up, which facilitates the movement of skims 1o1 o

 Soe1P1N Juplem camera 6 of filtertrat with input pumping station 2, .acr-yy, then there is no outflow of liquid from the filter, the level in chamber 5 of the original liquid. how much is 1h, i; o not so that the liquid can flow through the overflow pipe 12 get FI tank 3, since}: the filter regeneration rem occurs in a short period of time (1-2 minutes). After the conveyor 8 is moved to the hall, the en-Hofi step and a part of the filter panel 4 or filter material K) is sent, a signal is given to the end of the regeneration. The conveyor 8 stops, the valves 14 and 16 are closed, the valve 19 opens, soy; the filtrate chamber 6 with the inlet of the pumping station 2 opens; The filtration process begins.

If, as a result of frequent regenerations of the lost liquid in tank 3, drops significantly below the 7 "in level and there is a danger of a lack of liquid to build up and supply to the machines during regeneration, a signal is given to open the shut-off valve 22, the liquid is added to the level tank}, necessary for pa6oTtii filter in the regeneration process.

At the end of the work of the machine tools - the coolant consumers, a signal is given to close the shut-off valve 23 and open the extractor valve 22, the coolant through the tray 24 enters the filter chamber 5 ;; 1, Φ; 1. It is filled and supplied by the station 2 by pipelines 20 and 21 to fill the tank 3. When the tank 3 is filled to the overflow level into the chamber 5 of the original fluid, the filtration unit is turned off.

The plant has a high expat ability due to the fact that, in the first place, in any cycle of the plant operation on machines

It is only obvious that it increases the durability of iu; f; yiuei4i tool: the quality and quality of parts, and secondly, due to the presence of a liquid level filter that is minimally necessary for operation: pump, the scraper conveyor of the frame will be taken out during regeneration in the zone ki dehydrated psham that no4FU iHi-T reduce the cost of its transportation and processing.
