Abstract
As the requirements on aspects like ventilation, fire control and smoke discharge, appearance, noise and adapters mounting of office buildings and plant buildings are constantly improved, the current centrifugal ventilators can not adapt to demands. The utility model discloses a box type centrifugal ventilator which is characterized in that a box body is covered outside a shell; one end surface of the box body is provided with an air inlet; the other end surface of the box body is provided with an air outlet; two side surfaces of the shell are respectively provided with one lateral air inlet; vanes consist of multi-wing anteverted vanes and back-bent sheet vanes; the number of the multi-wing anteverted vanes is 38-48 and the number of the back-bent sheet vanes is 12-16; a motor is arranged outside the box body; and the motor is connected with a spindle through a belt. The fan efficiency is improved through the optimal design on the vanes; and the effects of energy saving and noise reduction are achieved by adding the box body of the fan.

Technical field
The utility model relates to the ventilating engineering apparatus field, specifically a kind of box centrifugal blower.
Background technique
Along with popularizing of China's tall building, the conventional centrifugal blower that the ventilation system that matches is with it used, because the Environmental Conditions noise requirements is high and limited by the place, be difficult to reach requirement of system design in fire-fighting smoke evacuation function aspects, installation and removal are extremely inconvenience also.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of reasonable in design, compact structure, in light weight, efficient is high, noise is low box centrifugal blower are provided.
For this reason, the utility model adopts following technological scheme: a kind of box centrifugal blower, comprise casing, impeller is housed in the casing, impeller is made of shroud, hub disk, blade and the axle sleeve that is installed on the main shaft, it is characterized in that described casing is covered with a casing, and an end face of casing forms an intake grill, the other end forms an exhaust outlet, and a side air admission mouth respectively is housed on the bi-side of casing; Described blade is by being lean forward shape blade and be the lamellar blade of palintrope and form of multiple wing, and the lean forward number of blade of shape of multiple wing is the 38-48 sheet, and the laminal number of blade of palintrope is the 12-16 sheet; Casing is provided with motor outward, and motor is connected with main shaft by belt.The utility model has carried out optimal design according to hydromechanical basic principle to blade structure on the impeller and quantity, makes the aeroperformance of impeller more reliable, has improved fan efficiency.Motor is positioned over the outside of casing, and make motor avoid contacting high-temperature gas, make it to have excellent specific properties such as volume is little, in light weight, high temperature resistant, convenient for installation and maintenance, both be applicable to the ventilation of factory and building, also can be used for the fire-fighting smoke evacuation of buildings such as office building.
Above-mentioned box centrifugal blower, casing is made up of the framework coaming plate outer with being connected framework, is filled with the noise elimination glass wool in the coaming plate, makes it have comparatively ideal energy-saving and noise-reducing effect.
Above-mentioned box centrifugal blower is equipped with drive pulley on the motor output shaft, on the described main shaft driven pulley is housed, and described belt is connected drive pulley with driven pulley.
Above-mentioned box centrifugal blower, belt is provided with belt hood outward, is used to protect belt.
The utility model has carried out optimal design to the structure and the quantity of blade, and the aeroperformance of impeller is more reliable, has improved fan efficiency; Casing has comparatively ideal energy-saving and noise-reducing effect; Have excellent specific properties such as volume is little, in light weight, convenient for installation and maintenance; Impeller is two air inlet structures, can be according to the actual demand of erecting bed, and the direction of the various inlets and putlets of ventilation of combination in any greatly facilitates the needs that site operation is connected with pipeline.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
