Abstract

The invention allows to improve the quality and productivity of cleaning due to the fact that cleaning is performed using a rotating head 1, the body 3 of which has face nozzles 2 and side nozzles 10. The head 1 is placed in the casing 11 having channels 12 through which the contaminated working fluid For removal of contaminants from under the body 3 of the head 1, the end nozzles 2 are made at a different angle to the axis of the head 1, which increases depending on the increase in distance from the nozzles to the axis of the head. The cleaning zone under the casing 11 is sealed off from the environment by means of an elastic element in the form of a ring 14. 3 CI f-ly, 2 ill. 16 P VU.2.1 CL ND CO O) HCHE with co

Description

The invention relates to the cleaning of articles, namely, devices for cleaning containers, such as hydraulic tanks of construction machines, and settled soils.

The purpose of the invention is to improve the quality and performance of cleaning.

FIG. 1 shows a device for cleaning surfaces, a cut; in fig. 2 shows section A-A in FIG. one.

Surface cleaning device

Water 5, connected to the suction line. The working fluid is discharged from under the casing, and the ring 14, under the action of a vacuum, fits snugly against the surface being washed. The working flushing fluid is supplied through the supply pipe 4 into the cavity of the housing 3 of the washing head 1, to the side 10 and end 2 nozzles. Under the action of a jet from the side nozzles, the housing 3 is rotated

It has a washing head 1 with a rigid spacing of the washing head 1, rinsing with circular zozzy nozzles 2 for washing out and transporting contaminants from under the head to the suction zone. To better remove contaminants from under the body 3 of the head 1, the end nozzles 2 are made under different

The surface of the bottom under the casing And, and the liquid jets from the end nozzles 2 wash the surface under the rotating body. At the same time, the jets of fluid transport the contaminants to the area

an angle to the axis of the head 1, which increases the suction 16, from where the contamination together

with the fluid through the channels 12 formed by the surface of the casing 11 and the membrane 13 is discharged through the pipeline 5 from the rinsed tank to the installation for cleaning liquid 0 ° b 0 ° and is determined experimentally., from contamination and repeated use L .ft

depending on the increase in distance from the nozzles to the axis of the head.

The angle of inclination a to the axis of the head of the end nozzles 2 varies within

the formula

where g is the radius of the face nozzle from the axis of the head;

D - diameter of the casing 3 heads 1.

The device also has a supply pipe 4, connected to the delivery line, and a discharge pipe 5, connected to the suction line, placed relative to each other coaxially. The supply pipe has a bearing b fixed by a nut 7, on which case 3 is mounted with a cover 8 and a seal 9. Case 3 is provided with side nozzles 10 for driving it in rotation

call. The elastic element in the form of a ring 14 creates a reliable sealing of the flushing zone under the casing due to the overpressure of the surrounding liquid, since the cavity under the casing is connected to the suction - 25 by the main line, where the vacuum is constantly maintained. Under the action of the pressure difference, the ring 14 fits snugly to the surface of the tank bottom and prevents the working flushing fluid from mixing with the surrounding.

The device allows flushing the container without draining the liquid from it, with known areas of accumulation of contaminants on the bottom surface. The invention makes it possible to reduce labor costs, washing time and head 1 and erosion of contaminants. 35 to increase the cleaning efficiency when the service pipeline 5 passes into a hemispherical case 11 with hollow channels 12 on its inner surface, to which an elastic membrane 13 adjoins, fixed on the supply pipe and closing hollow channels. The channels formed by the surface of the casing and the membrane connect the suction zone at the base of the casing with the discharge pipe. The outer surface of the hemisphere of the casing snab40

living, for example, the hydraulic systems of construction machines in the conditions of operation and in all cases when it is impractical to drain the liquid from the container. The invention also makes it possible to improve the quality of cleaning of the hydraulic tank, which leads to a decrease in the pollution of the hydraulic system, an increase in the service life of the hydraulic units, and improves the working conditions of the personnel, as the washing is performed in a closed elastic element in the form of a ring 45 that is insulated from the environment.

14, which separates the internal cavity from the surrounding liquid due to intimate contact with the surface of the flushing bottom of the tank 15. The circular suction zone 16 formed at the base of the hemisphere by the surface of the casing and the bottom, sealed by an elastic element in the form of a ring, is connected through channels to the discharge pipe .

The device for cleaning surfaces works as follows.

The device is immersed in a liquid on a known contaminated bottom of the tank.

Claims (4)

1. A device for cleaning surfaces, including a washing head with rigid end nozzles arranged at an angle to the axis of the head, connected to the head supply pipe, characterized in that, in order to improve the quality and productivity of cleaning, the nozzles are located in the direction from the center to the periphery butt end Water 5, connected to the suction line. The working fluid is discharged from under the casing, and the ring 14, under the action of a vacuum, fits snugly against the surface being washed. The working flushing fluid is supplied through the supply pipe 4 into the cavity of the housing 3 of the washing head 1, to the side 10 and end 2 nozzles. Under the action of a jet from the side nozzles, the housing 3 is rotated the washing head 1, washing the circular area of the bottom surface under the casing And, and the liquid jets from the end nozzles 2 wash the surface under the rotating body. At the same time, the jets of fluid transport the contaminants to the area suction 16, from where the contamination together .,., tee from contamination and reuse it f .ft call. The elastic element in the form of a ring 14 creates a reliable sealing of the flushing zone under the casing due to the overpressure of the surrounding liquid, since the cavity under the casing is connected to the suction - 25 by the main line, where the vacuum is constantly maintained. Under the action of the pressure difference, the ring 14 fits snugly to the surface of the tank bottom and prevents the working flushing fluid from mixing with the surrounding. thirty The device allows flushing the container without draining the liquid from it, with known areas of accumulation of contaminants on the bottom surface.
