Description
Technical field
The utility model relates to a kind of without spiral case fire-fighting draft fan case.
Background technique
Be provided with volute of blower outside its centrifugal impeller of air box used at present, the setting of volute of blower makes blower fan can only have 1 exhaust outlet, therefore must take into account the setting of air port and exhaust outlet when mounted, add cost and the installation period of installation.And the temperature of cabinet easily raises when air box long-play, in blower fan driving mechanism at high temperature work for a long time easily distortion, melt thus affect the normal use of air box.
Model utility content
The purpose of this utility model is to provide a kind of without spiral case fire-fighting draft fan case, arranges and enables the air-out of air box multi-angle, be applicable to the installation of different occasion different amount, reduce installation cost and installation period without spiral case; Seal diaphragm and aluminum alloy shaft seal with the use of effectively having isolated contacting of driving mechanism and high temperature gas flow, thus the problem that effectively prevent driving mechanism distortion, melt, effectively improves the working life of air box.
In order to achieve the above object, the technical solution of the utility model is:
A kind of without spiral case fire-fighting draft fan case, comprise casing, described casing offers respectively the exhaust outlet of intake grill and more than 1, impeller supporting post is installed in described casing, described impeller supporting pillar is provided with impeller, described casing is provided with motor, is provided with seal diaphragm in the casing between described impeller and motor, described motor is connected with impeller through after seal diaphragm by driving mechanism.
Described driving mechanism comprises motor transmission shaft, impeller shaft, described motor transmission shaft is provided with the first drive wheel, described impeller shaft is provided with the second drive wheel, is provided with V-type vee belt between described first drive wheel and the second drive wheel.
Described impeller shaft is connected with seal diaphragm by aluminum alloy shaft seal.
Offer the first exhaust outlet on the upside of described casing, offer the second exhaust outlet on the downside of described casing, offer the 3rd exhaust outlet on the left of described casing, described casing right side opening is provided with the 4th exhaust outlet, offers the 5th exhaust outlet on rear side of described casing.
Described impeller adopts BI centrifugal impeller or the multiple wing type centrifugal impeller that leans forward.
The beneficial effects of the utility model are: a kind of without spiral case fire-fighting draft fan case, arrange and enable the air-out of air box multi-angle, be applicable to the installation of different occasion different amount, reduce installation cost and installation period without spiral case; Seal diaphragm and aluminum alloy shaft seal with the use of effectively having isolated contacting of driving mechanism and high temperature gas flow, thus the problem that effectively prevent driving mechanism distortion, melt, effectively improves the working life of air box.
