Abstract
The utility model discloses a centrifugal ventilator used for indoor and outdoor ventilation of buildings of industrial and mining enterprises and used for solving the problems that an existing ventilator is low in efficiency and high in noise. The centrifugal ventilator comprises an air outlet, a machine case, an inlet flow collector, an impeller, a connecting shaft, a motor and supports. The motor is fixedly connected to the machine case through bolts. The motor is connected with the supports through bolts. The motor is connected with the impeller through the connecting shaft. The air outlet is arranged on the machine case. The inlet flow collector is connected with the machine case through bolts. The centrifugal ventilator is characterized in that the inlet flow collector is of a circular arc-shaped structure and is installed on the side face of the machine case; the machine case is integrally of an elliptic hollow structure; the impeller is a three-dimensional flow impeller, vanes of the impeller are curved vanes, and the number of the vanes is eight.
Description
Technical field
The utility model relates to a kind of machinery for industrial and mining enterprise's Indoor environment separate ventilation ventilation, especially a kind of high efficiency, the slow-speed of revolution, low noise centrifugal blower.
Background technique
Ventilator is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Ventilator is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building.China in Recent Years blower fan industry has been developed a series of new high-efficiency blower fans, particularly along with the continuous digestion of introducing technology and perfect, Siping City, heavily logical high-temperature blower, the industrial fan of Xishan Mountain Beijing area, Shen drum, upper drum etc. obtains user's accreditation gradually, and this brings great economic effect to factory.But China still has the old blower fan of multiple poor efficiency to need to update, and the new blower fan of promoting also awaits further perfect.Therefore, China should improve constantly Fan Product quality, the demand of stabilizing the market, and also wants the positive import of advanced technology, and development ability develops skill; With famous brand strategy, exploit market energetically; Promote blower fan enterprise development with economic scale.Along with scientific and technical development, the requirement that people use blower fan is also more and more higher, with regard to current state inner blower technology trends, by the future development along constantly increase of fan capacity, high efficiency, high-speed small-size and low noise.
Summary of the invention
In order to solve existing fan efficiency lowly and the defect of high noisy, the utility model provides a kind of centrifugal blower, not only efficiency is high, rotating speed is low for this centrifugal blower, noise is few, and has novel structure compactness, vibrates little, feature easy to adjust while using.
The utility model solves the technological scheme that its technical problem adopts: a kind of centrifugal blower, comprise air outlet, casing, import slip ring, impeller, joining shaft, motor, support, described motor is bolted to connection on casing, motor is connected with support by bolt, motor is connected by joining shaft with impeller, casing is provided with air outlet, import slip ring and casing are bolted, described import slip ring adopts structure in the arc-shaped, described import slip ring is installed on the side of casing, described casing is overall oval hollow structure, described impeller is ternary flow impellers, described impeller blade is curved blade, described impeller blade number is eight.
When centrifugal blower work, the rotation of motor rotation drives impeller, air sucks from suction port, and from axially entering impeller, gas flow changes over radially in the time of impeller.In the blade rotation process of centrifugal blower, to gas exerts dynamic action, improve pressure and the speed of gas, gas is discharged from air outlet in the effect Xia Yanye road of centrifugal force.
The beneficial effects of the utility model are, improving overall efficiency, are falling the low noise while, also have little, the fitting operation of taking up room and use simple, feature easy to adjust while using.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is longitudinal section of the present utility model tectonic maps.
1. air outlets in figure, 2. casing, 3. import slip ring, 4. impeller, 5. joining shaft, 6. motor, 7. support.
Embodiment
Please refer to Fig. 1, motor 6 is bolted to connection on casing 2 sides, and motor 6 bottoms are connected with support 7 by bolt, and motor 6 is connected by joining shaft 5 with impeller 4, and casing 2 afterbodys are provided with air outlet 1, and import slip ring 3 is arranged on casing 2 sides by bolt.Impeller 4 blades are curved, and number is eight, the sound having produced while having reduced vane rotary; Import slip ring adopts structure in the arc-shaped, reduces the distinguished and admirable drag losses of entrance, thereby has increased speed and the blast of air.
By reference to the accompanying drawings the utility model is carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or say that without improvement design of the present utility model and technological scheme are applied to other occasions, all in protection domain of the present utility model.
