Description

  . ; :; . .:.

The invention relates to devices intended for cleaning industrial premises and, in particular, for cleaning an electrically-electrifying PIL. . -. ; V -. ; ../

Known vacuum cleaner, in the case of which is placed a liquid filter. Above the liquid filter is mounted a booster T51gi, made in the form of an žek, torus l

This device captures well HBaiOTck cMa only large parts contained in the inhaled gas. Such dust particles, size l, which are calculated in microns, such as aluminum sulfur dust, are not smeared with water.

As a result, the carried urinated particles quickly electrified, leading to the awkwardness of the fire or explosion.

The purpose of the invention is to increase by: heat. and explosion protection when cleaning electrified dust;

This is achieved by the fact that the farmer is equipped with zishitnyh mesh to the edges, installed in the cortus between the electrode and the liquid filter, the axis of the ejector is at an acute angle to the surface of the liquid filter, and the liquid filter is connected to the mixing chamber of the ejector.

In addition, the inner surface of the housing and the ejector may be. not from a material of the cleaned dust.

The drawing shows the proposed device, the cut.

Liquid filter 2 is placed in vacuum cleaner 1 (water filling the part of the vacuum cleaner body), and a liquid booster 2 is mounted on the vacuum cleaner 3; the ejector 3 and the liquid filter 2, and the axis of the ejector 3 is located under the Acute angle to the surface of the liquid filter 2,

which communicates with the mixing chamber of the ejector 3, for example, through the tube 5, having an air flow m, an adjustable flow area (not shown).

The vacuum cleaner kit includes a hose 6, states of metal tubes, a flexible link 7, and nozzles 8. At the bottom of the juraus 1 there is a tap 9 for sludge running. The ejector 3 is mounted on the housing 1 with the hinge 10. The tube 11 is designed to supply gas or steam to the ejector 3. One of the walls of the housing 1 of the vacuum cleaner on the side facing the diffuser of the ejector 3, has an additional protective screen 12.

The vacuum cleaner works as follows

Soap powder or other material is added to the liquid filter 2 to reduce the surface tension of water. The vacuum cleaner is connected to a compressed air, gas or steam line. A hose 6 with a nozzle -8 is attached to the ejector 3 and the cleaning is started. Because of: the dilution caused by the ejector 3, the dusty air enters through the slider b into the body 1 of the vacuum cleaner.

A jet of dusty air, the top of the ejector 3, strikes an additional protective screen 12, runs down along it and interacts with the water, mixing and foaming it. On the surface of the filter 2 is soapy. Powder helps to retain and sticking dust particles. In consequence of the dilution supplied by the ejector 3, part of the water enters through the tube 5. into the mixing chamber of the ejector 3, as a result of which the sucked dust-laden air is moistened, which contributes to the leakage of static electricity generated by the dust in the nozzle 8 and Po hose 6.

When the inner part of the ejector 3, the hose 6 and the internal rotation of the body 1 are made from the material of the dust to be removed (for example, when cleaning aluminum, dust from aluminum), the intensity of electrification processes is minimal. ...

. Protective mesh screens 4 on one side contribute to foaming all over, while the other side is a barrier to the 2 particles, which are not caught by the filter, trying to fly out into the surrounding space.
