Description

Smoke exhauster dust collector represents the centrifugal fan combined with the dust collector; consists of the smoke exhauster, entrance "snail", and gas flues. The smoke exhauster dust collector shaft - two-basic, is connected by the rigid coupling to the electric motor. On a shaft the driving wheel and an additional krylchatka is installed. Gas is purified of dust in entrance "snail". Thanks to such scheme of cleaning the driving wheel and his "snail" are protected from abrasive wear.

The smoke exhauster dust collector in comparison with separate installation of the smoke exhauster and cyclones at equal efficiency of cleaning possesses smaller metal-and power consumption, small dimensions, does not demand for placement of the additional areas. Along with purification of gas the smoke exhauster dust collector can return the caught ashes in a copper fire chamber on reburning. In this case the portable cyclone sets in directly on a copper with a conclusion of the caught ashes through a strut and a flasher in a copper fire chamber.

Productivity of the device is regulated by the language shiber established in a branch pipe of entrance "snail". Management of a shiber remote.

Principle of work

Movement of gas happens at the expense of the difference of pressure created by the driving wheel on a shaft. Under the influence of centrifugal forces dust is rejected to the periphery and together with a small amount of gas (8 ÷ 10%) the branch pipe during the portable small-sized cyclone connected to "snail" of the dust collector the gas flue is taken away for final office through pyleotvodny. Unloading of a cyclone in a pylepriyemnik is made via the tight bunker or spuskny a strut with a lock flasher. From a cyclone the cleared stream of gas comes back to the central part of "snail".

The dust concentrate prosasyvatsya through a cyclone under the influence of difference of pressure between the center of "snail" and its periphery; difference of pressure increases due to work of an auxiliary krylchatka. From the central zone "snails" the purified gas via the directing device comes to the driving wheel of the smoke exhauster, and then through a casing is thrown out a chimney.

Regulation of productivity of the smoke exhauster is carried out by a shiber when whose closing the stream is wrung out to the periphery of "snail". For protection of walls against wear the protective peaks from strip steel located on sidewalls of "snail" in a peripheral zone are provided.
The cyclone is established in the place convenient for unloading of the caught dust.
