Abstract

The utility model relates to a high air pressure closed volute shell fan which includes an electric motor and a fan shell; an air inlet tube and an air outlet tube are arranged on the fan shell; a turbine vane is arranged in the fan shell; the electric motor is connected with the turbine vane by a rotary shaft and can drive the turbine vane to rotate; the contact location of the rotary shaft of the electric motor and the fan shell is provided with an uni-directional O-shaped seal ring; the outer circle of the uni-directional O-shaped seal ring is provided with an annular groove and can be embedded with the fan shell; the two sides of the central hole of the uni-directional O-shaped seal ring are respectively provided with conical annular sides. A sealed cavity is formed in the shell, thus being capable of reducing air flow leakage and improving the exhaust pressure; during the working process of the conical annular sides arranged at the two sides of the uni-directional O-shaped seal ring, a converse pressure generates on the conical incline thereof, and the larger the air pressure is, the higher the seal performances are, thus enhancing the seal effect, improving the air pressure and the working efficiency of the fan under the foundation of the same flux, reducing the power consumption and saving more energies.

Description

The airtight volute blower of a kind of high blast
Technical field
The utility model relates to blower, particularly a kind ofly can produce high blast, and housing adopts airtight volute blower.
Background technique
At present, traditional blower generally all comprises motor and blower casing, and blower casing is provided with air intake pipe and air outlet tube, is provided with turbine blade in the blower casing, and motor is connected with turbine blade by rotatingshaft and can drives the turbine blade rotation.The exhaust air rate of this class blower is all bigger usually, when being used for requirement and producing the negative pressure of high blast low discharge or positive pressure environment, because air draft or air intake direction produce resistance, have big pressure in the blower casing and on the turbine blade, mass air flow leaks from the slit on the blower casing, make that the blast of blower is not high, working efficiency reduces, and power consumption increases, can not resistance to compression, reduce the function of blower, limited its application area.
The model utility content
At the deficiency of above existing blower, the purpose of this utility model provides and a kind ofly can produce higher blast, and working efficiency improves, and power consumption reduces, the blower that volute is airtight.
The purpose of this utility model is achieved by the following technical solution:
The airtight volute blower of a kind of high blast, comprise motor and blower casing, blower casing is provided with air intake pipe and air outlet tube, be provided with turbine blade in the blower casing, motor is connected with turbine blade by rotatingshaft and can drives the turbine blade rotation, described motor rotation axis and blower casing contacting point are provided with unidirectional O-ring seals, the excircle of unidirectional O-ring seals be provided with annular groove and can with the blower casing tabling, unidirectional O-ring seals center hole both sides are respectively equipped with the tapered collar limit.
As optimal technical scheme of the present utility model, the side of described blower casing is provided with housing lid, is provided with sealing gasket between housing lid and the blower casing.
As optimal technical scheme of the present utility model, also be provided with sealing gasket between bolt that described blower casing is provided with and the blower casing.
The beneficial effects of the utility model are: by above structure as can be known, can form the inner chamber of a sealing in the blower casing, when the motor drives turbine blade rotates, can reduce flow leakage, improve air draft pressure.The tapered collar limit that unidirectional O-ring seals both sides on the motor rotation axis are provided with, in the blower working procedure, can produce reverse pressure on its circular cone inclined-plane, big more its sealing of blast is high more, strengthened the sealing effect of blower casing intracoelomic cavity, on the basis that produces same traffic, improve the blast and the working efficiency of blower, reduced power consumption, more energy-conservation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a main TV structure schematic representation of the present utility model;
Fig. 3 is the sectional view of unidirectional O-ring seals in the utility model.
Embodiment
