Abstract
The utility model relates to a two-way ventilative anti-explosion vetilator which comprises an air duct (1), an anti-explosion frequency conversion motor (2) and a frequency conversion controller (3), wherein 220 V alternating current is used for supplying power to the anti-explosion frequency conversion motor (2) through the frequency conversion controller (3), the anti-explosion frequency conversion motor (2) is fixed in the air duct (1), the air duct (1) is fixed on a support (4), the frequency conversion controller (3) is fixed on the support (4), and a ventilating impeller (5) is fixed on each of the two ends of a rotating shaft of the anti-explosion frequency conversion motor (2). The anti-explosion vetilator provided by the utility model has two functions of air supply and air exhaust, can supply air in a multichannel manner, and is very convenient to transport, install and place.
Description
Technical field:
The utility model relates to the ventilator technical field, more specifically to a kind of anti-explosion ventilator that can two-way ventilation.
Background technique:
Existing ventilator generally only has unidirectional air-supply or exhausting function, can't have air-supply and exhausting binomial function simultaneously.In some place, particularly mine, if anti-explosion ventilator has air-supply and exhausting function, then effect is better, and the one, to the down-hole air-supply, the 2nd, when the fire damp concentration over-standard, timely exhausting.If two anti-explosion motors are installed in the down-hole, then expense is too high, and it is big to take up room simultaneously.Simultaneously, because the space in the mine is narrower and small, need the air-supply of ventilator multichannel, some ventilator can't be accomplished.Some anti-explosion ventilator, very inconvenience of carrying and placement.These shortcomings are badly in need of improving.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of anti-explosion ventilator of two-way ventilation is provided, and it has air-supply and exhausting binomial function, can blow by multichannel, transports, installs and place very convenient.
The technological solution of the utility model is following:
A kind of anti-explosion ventilator of two-way ventilation; Comprise air duct, flame-proof converter motor and frequency-variable controller; The 220V Ac is given the power supply of flame-proof converter motor through frequency-variable controller, and the flame-proof converter motor is fixed in the air duct, and air duct is fixed on the support; Frequency-variable controller is fixed on the support, and rotating shaft two ends of flame-proof converter motor are fixed with the ventilation impeller respectively.
Be welded with hanger on the said air duct.
Said air duct two ends form flange plate, and " people " font airduct connects on flange plate.
The beneficial effect of the utility model is:
1, it rotates and reverse through the flame-proof converter motor and drives the ventilation impeller and rotate and reverse, thereby realizes exhausting and air-supply.
2, its installation is very convenient, directly docks with airduct through flange plate, both can connect the ventilation duct in an air channel, also can connect the airduct in two air channels through " people " font airduct, realizes multichannel air-supply and exhausting.
When 3, transporting, the utility model is sling, directly be placed on the mounting point through support through hanger, very convenient.
Description of drawings:
Fig. 1 is the schematic perspective view of the utility model
Fig. 2 is the annexation schematic representation of flame-proof converter motor and ventilation impeller
Among the figure: 1, air duct; 2, flame-proof converter motor; 3, frequency-variable controller; 4, support; 5, ventilation impeller; 6, hanger; 7, " people " font airduct; 101, flange plate.
Embodiment:
Embodiment: see Fig. 1, shown in 2; A kind of anti-explosion ventilator of two-way ventilation comprises air duct 1, flame-proof converter motor 2 and frequency-variable controller 3, and the 220V Ac gives the flame-proof converter motor 2 power supplies through frequency-variable controller 3; Flame-proof converter motor 2 is fixed in the air duct 1; Air duct 1 is fixed on the support 4, and frequency-variable controller 3 is fixed on the support 4, and rotating shaft two ends of flame-proof converter motor 2 are fixed with ventilation impeller 5 respectively.
Be welded with hanger 6 on the said air duct 1.
Said air duct 1 two ends form flange plate 101, and " people " font airduct 7 connects on flange plate 101.
Working principle: it rotates and reverse drive ventilation impeller 5 through flame-proof converter motor 2 and rotates and reverse, thereby realizes exhausting and air-supply.
It installs very convenient, directly docks with airduct through flange plate 101, both can connect the ventilation duct in an air channel, also can connect the airduct in two air channels through " people " font airduct 7, realizes multichannel air-supply and exhausting.
During transportation, the utility model is sling, directly be placed on the mounting point through support 4 through hanger 6, very convenient.
