Description

Impeller exhaust system with improved assembly}

The present invention relates to an impeller exhaust device with improved assembly, and more particularly, an exhaust casing and a rear cover of an impeller fixed frame in an exhaust device for exhausting air inside underground structures such as underground parking lots and tunnels to the outside It was invented to improve the convenience and work efficiency of installation and repair work by configuring it to be assembled on a plate more easily.

In general, underground structures such as underground parking lots and tunnels are provided with an air conditioning ventilation device that circulates air by exhausting internal air of a closed space and taking in external air in consideration of the exhaust problem of combustion gas generated from vehicles.

Here, the exhaust system should be designed to keep the pollution level constant by exhausting the internal air in a mechanical or natural convection manner, and in the case of a large parking lot or a long-distance tunnel, it operates independently for each zone It is effective to exhaust the indoor air to the outside.

1 is a schematic cross-sectional view showing the structure of a conventional stand-alone exhaust device, a front cover plate 30 including an intake port 31' in front of an exhaust casing 20' in the shape of an enclosure to intake indoor air and exhaust it to the outside. ') is fastened, and a rear cover plate 40' including an exhaust port 41' is fastened to the rear, and is located inside the housing and sucks indoor air through the intake port 31' to the exhaust port 41') The driving motor 50' including the impeller (B') discharged to the furnace is fixedly mounted to the front cover plate 30' through the impeller holder T'.

Here, the driving motor 50' fixed inside the housing and driving the impeller B' is fixed to the impeller holder T' of the front cover plate 30', and the impeller (B') or When replacing and repairing the driving motor 50', the front cover plate 30' is separated, and the impeller B' and the driving motor 50' are also separated.

However, in the exhaust device configured as described above, since the impeller and the driving motor are assembled only on the front cover plate of the exhaust casing, the center of gravity is deflected to the front and the weight is excessive. There was a problem that the installation work was difficult because it did not fit.

In addition, in a state in which the impeller and the driving motor are coupled to the front cover plate, the driving motor cannot be stably supported during the operation of the exhaust device, that is, when the impeller rotates due to the operation of the driving motor. There was a problem that this occurred.

In addition, in the process of combining the front cover plate with the impeller and the driving motor in the exhaust casing mounted on the upper part of the wall of the underground parking lot and tunnel, the heavy front cover plate fell or was misassembled, and there was a problem that a safety accident occurred.

In addition, in order to clean or repair the impeller, the front cover plate to which the impeller and the driving motor are integrally coupled must be completely separated.
