Abstract
The utility model relates to a centrifugal air feeder, wherein the technical proposal which is solved is that the air feeder which is provided has the characteristics of convenient installation, excellent stability after mounting, low noise, simple structure and low manufacturing cost. The technical proposal is that the centrifugal air feeder comprises a body case, and an impeller and an impeller shaft which are arranged in the body case, wherein the impeller sleeve is mounted on the impeller shaft, the impeller shaft extends outside the body case from the body case, a motor is arranged outside the body case, and the impeller shaft and the motor output shaft are connected in a driving way. The centrifugal air feeder is characterized in that the body case is a rectangular body structure.
Description
Technical field
The utility model relates to a kind of centrifugal blower, is specially a kind of centrifugal blower of being convenient to install.
Background technique
Traditional centrifugal blower shell is the volute type structure mostly, is vulnerable to the restriction of mounting point and required type during installation, can not directly gas fan be fixed on the desired position.After often needing earlier motor base to be fixed on desired location, utilize the hole on the motor base that blower casing is fixed on the desired location again.Though, can change the setting angle of blower casing by regulating the mutual alignment between motor flange and the blower casing; But still there are problems such as inconvenience, constructional difficulties are installed.And when blower casing was fixed in desired location by the hole on the motor base, close together between the hole on the motor base and the impeller of rotation caused gas fan noise when work bigger.
The model utility content
The purpose of this utility model is to overcome the problems referred to above that exist in the background technique, a kind of centrifugal blower that can satisfy various installation occasions is provided, easy for installation, the installation characteristics that rear stability is good, noise is low that this gas fan should have, and simple in structure, low cost of manufacture.
The technological scheme that the utility model proposes is:
A kind of centrifugal blower comprises casing and is arranged on casing interior impeller and impeller shaft that described impeller set is contained on the impeller shaft, and impeller shaft extends to outside the casing in casing; The casing outside also is provided with motor, and impeller shaft and motor output shaft are in transmission connection, and it is characterized in that described casing is the cuboid structure.
Described impeller shaft and motor output shaft are coaxially set, and are in transmission connection by flange.
The output shaft of described impeller shaft and motor be arranged in parallel, and connects by belt transmission.
Be shaped on frame around the described casing, frame is provided with mounting hole.
The beneficial effect that the utlity model has is: make traditional scroll casing shape flow blower casing into the square shell, and mounting hole is directly opened after the frame of square flow blower casing, four limits of shell all can be used as the fixing usefulness of blower fan, multiple mode such as specifically can adopt lifting, paperback, mount according to different occasion, not only can satisfy the installation requirements of various occasions, the installation of fan brings great convenience; And install time saving and energy savingly, improved construction speed widely; In addition and since on the gas fan frame fixed hole distance between the impeller that rotates far away, also have advantages such as good stability, vibrations are little, noise is low during use.
Description of drawings
Fig. 1 is the utility model embodiment 1 a stereogram.
Fig. 2 is the utility model embodiment 2 a stereogram.
Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further by embodiment.
A kind of centrifugal blower comprises casing 1 and is arranged on casing interior impeller and impeller shaft that described impeller set is contained on the impeller shaft, and impeller shaft 4 extends to outside the casing in casing; The casing outside also is provided with motor 5, and described impeller shaft and motor output shaft are in transmission connection.More than for having the conventional structure of centrifugal blower now.
The improvement that the utility model relates to is that the centrifugal blower casing with traditional scroll casing shape structure changes the cuboid structure into, and is shaped on frame 6 around the shell, and mounting hole 6-1 directly is opened on the frame of gas fan casing.Centrifugal blower after the improvement have easy for installation flexibly, advantages such as rear stability is good, vibrations are little, noise is low are installed.
Centrifugal blower mainly contains two kinds on cold wind type and hot blast type, as two embodiments of the present utility model.Embodiment 1 is a cold wind type gas fan, and as shown in Figure 1, the outer surface of casing also is provided with motor, extend to casing outer impeller shaft and motor output shaft and be coaxially set, and by the fixing back of flange transferring power.Embodiment 2 is a hot blast type gas fan, and as shown in Figure 2, the outer surface of casing is by the motor cabinet fixed electrical machinery, and described motor output shaft is parallel with the impeller shaft outside extending casing, is in transmission connection by belt 7 between impeller shaft and the motor output shaft.
The utility model is not limited to above-mentioned mode of execution, everyly the centrifugal blower casing is arranged to the cuboid structure all drops within the protection domain of the present utility model.In addition can be directly outside original scroll casing shape structural housing socket one cuboid again, making its finally shaped casing is the cuboid structure, also should think and drop within the utility model protection domain.
Claims (4)
1, a kind of centrifugal blower comprises casing (1) and is arranged on casing interior impeller and impeller shaft that described impeller set is contained on the impeller shaft, and impeller shaft (4) extends to outside the casing in casing; The casing outside also is provided with motor, and impeller shaft and motor output shaft are in transmission connection, and it is characterized in that described casing is the cuboid structure.
2, centrifugal blower according to claim 1 is characterized in that described impeller shaft and motor output shaft are coaxially set, and is in transmission connection by flange.
3, centrifugal blower according to claim 1 is characterized in that the output shaft of described impeller shaft and motor be arranged in parallel, and is in transmission connection by belt (7).
