Abstract

The invention relates to devices for cleaning liquid circulating in a closed loop, having water and can be used in thermal power plants, in public utilities, in chemical production for cleaning technical, network circulation water. The purpose is to increase the operational reliability and efficiency of devices the expense of cleaning fluid and dumping debris — solids from the circulation circuit. A coarse liquid cleaning device contains a housing that connects the inlet and outlet nozzles to a rotating filtering surface with a drive shaft. The filtering surface has the shape of a twelve-sided pyramid divided by diagonal solid partitions with edges along the edges creating filter washing zones. and outlet nozzles. Debris removal from the circuit is performed in the garbage collector; rotation of the filter element from right to left is 3 silt

WITH

The invention relates to devices for the purification of a circulating fluid in a closed loop, which has a make-up and can be used in thermal power plants, in the communal household, in chemical production for the purification of technical, network, circulating water.

The aim of the invention is to increase the operational reliability and efficiency of devices by cleaning the liquid and discharging solid particles from the circulation circuit.

FIG. 1 shows a coarse liquid cleaning device; figure 2 - section aa nafig.1; nafig.Z-section bb in fig 1

The device includes a housing 1 with inlet 2 and outlet 3 nozzles of pressure fluid and input 4 and outlet 5 nozzles of the drain liquid located opposite each other axis of the nozzles parallel to the axis of the filtering device 6 which consists of diagonal dividers 7 with seals 8 along the perimeter and perforated sheets 9 forming a twelve-sided pyramid, the base of which ring 10, which plays the role of a support bearing and a circumferential seal. The filter device is supported on the shaft 11, installed th in the bearing 12 lower and thrust 13 upper bearings In the top cover of the housing 14 there are two screws XI

with a pressure of 15 for injecting a liquid ia. romyaku external filtering transfer. From here the pipe is connected by a pipe 16 with an outlet pressure pipe 3, the second port 17 for extraction of garbage from the internal filtering surface and discharge through the pipe 18 into the drive 19 There are also two holes in the bottom cover of the housing 20 for catching debris from the outer filtering surface and its removal through the pipe 22 into the accumulator 23, the second 24 for supplying liquid to the internal filtering core; the opening 24 through the pipe 25 is connected to the inlet discharge pipe 2

The device works as follows

Liquid with the inclusion of solid solids / months supplied by the pumps enters the device body 1 through the discharge port 2 passes through the filter device 6 foreign solid objects remain on the outside (to the inside of the filter element and out through the output pressure head / pipe 3 into the circuit in which extraneous solid objects are added. Drainage fluid from the circuit passes through the inlet drainage pipe 4, through the filtering surface. foreign solid objects remain on the inner surface of the filtering device. element and exits through the outlet drain nozzle 5 When the resistance in the pressure or drain section of the device is exceeded, the filter device shaft 11 is rotated. The contaminated filter element 9 turns and turns into a separating device between the pressure device and the drain part of the device, where the liquid is fed to the outer side of the filter element. through the pipe 16 and the hole 15 in the upper case cover, foreign solid objects washed away by the fluid flow are removed through the holes 21 in the lower case cover and beats all through pipe 22 into accumulator 23

In order to wash the outer surface of the filter element in the opposite separation zone, liquid is supplied through the nozzle 25 and the aperture 24 to the liquid picks up solid particles and through the aperture 17 and the nozzle 18

enters the accumulator 19 The washing is completed when the device is rotated by 180 ° dg to prevent liquid from flowing from the pressure zone to the drain zone; there are seals 8 at the ends of the separation sheets7

Such an embodiment of devices for coarse purification of fluid passing in parallel-laid pipes to the flow booster will allow cleaning the fluid and removing from the counter, hard solid objects, reducing the cost of installing an additional filter for cleaning the fluid
