Изобретение относитс к вентил ции и служит дл удалени вредных выделе-The invention relates to ventilation and serves to remove harmful emissions.

НИИ.SRI.

По основному авт. св. № 73121О известно устройство дл удалени вредных вьщелений с поверхности испарени технологической ванны, содержащее установленные вдоль бортов последней коллектор е отверсти ми и бортовой отсос с всасьшающей щелью, причем коллектор расположен в ванне, а отсос выполнен опрокинутым С 11 .,According to the main author. St. No. 73121O, a device for removing harmful inclusions from the evaporation surface of a process bath is known, which contains the last collector holes along the sides and a side suction with a suction gap, the collector located in the bath and the suction is made upside down With 11,

Недостатком известного устройства вл етс то, что с изменением уровн поверхности испарени приточна стру воздуха не нал пает на поверхность испарени , в результате чего происходит нрорыв вредностей.A disadvantage of the known device is that with a change in the level of the evaporation surface, the intake air stream does not fall on the evaporation surface, as a result of which the hazard is released.

Цель изобретени - повышение степени удалени вредностей.The purpose of the invention is to increase the degree of removal of hazards.

Псютавленна цель достигаетс тем, :что устройство снабжено направл ющими стойками и коллектор установлен на нихThe goal is achieved by the fact that the device is equipped with guide posts and a collector installed on them

с возможностью пбремешёйй и снабжен поплавковой камерой.with possibility of accession and equipped with a float chamber.

На фиг. 1 показано устройство дл удалени вредных выделений с поверхности испарени технологической ванны, обпшй вид; на фиг. 2 - разрез А-чА на |жг. 1.FIG. 1 shows a device for removing harmful discharges from the evaporation surface of a process bath, its appearance; in fig. 2 - A-chA incision on | zhg. one.

Устройство дл удалени вредных выделений с поверхности испарени технологической ванны 1 содержит установленto ные вдоль бортов ванны 1 коллектор 2 с отверсти ми 3 и бортовой отсос 4 с всасьшающей щелью 5, причем коллектор 2 расположен в ванне 1, а отсос 4 вьь ,, попнен опрокинутым. Кроме того, устройство снабжено направл ющими стойками 6, коллектор 2 установлен на них с возможностью перемещени снабжен поплавковой камерой 7. Приточный воздух подаетс в коллектор 2 по гибкому возду20 ховоду 8.A device for removing harmful discharges from the evaporation surface of the process bath 1 contains installed along the sides of the bath 1 a collector 2 with openings 3 and a side suction 4 with a suction gap 5, the collector 2 being located in the bath 1, and the suction 4 bn backfilled. In addition, the device is equipped with guide posts 6, the collector 2 is mounted on them with the possibility of movement and provided with a float chamber 7. The supply air is supplied to the collector 2 through a flexible air duct 8.

Claims

The device works as follows. 98 The intake air entering through the flexible duct 8 into the collector 2 is distributed through the openings 3 along the top of the harmful discharges by the sticky jet, entraining the harmful openings to the slit 5 of the tilted side suction 4, g in 01S and removing the hot air from the bath 1. When loaded or unloading parts or when evaporating and pouring the solution, the level of the latter in bath 1 varies within fairly wide limits. At the same time, the collector 2 is moved up or down along the guide pillars 6 by means of the float chamber 7, thereby maintaining the height of the openings 3 constant with respect to the evaporation surface, which ensures an adherent stream of adherent air and / thereby prevents breakthrough of harmful substances from the surface of evaporation into the workplace I. 6 4 The application of the invention allows a high degree of removal of harmful excretions from the surface of evaporations to be made, thus creating normal conditions for working around baths. Claims of the Invention A device for removing harmful deposits from the evaporation surface of a process bath according to the author. St. No. 731210, characterized in that, in order to increase the degree of removal of hazards, the device is equipped with guide posts and a collector installed on them with POSITIONING movement and equipped with a lifting chamber.
