Abstract
Couple-rotating axial-flow main ventilation fan with external placed electric motor belongs to a couple-rotating axial-flow ventilation fan. The device mainly solves technical problems that the existing main ventilation fan is high in cost, and easy to initiate safety misadventures, etc. The essential technique scheme is that: the device comprises blade wheels which are installed in a cylinder body and mutually couple-rotated, the inner end of the cylinder body and the air outlet are cooperatively installed and sealed, a long axis in gas-tight seal matching passes through the cylinder body or the air outlet to firmly connect with the blade wheel installed in the cylinder body, and the outer end of the long axis is firmly connected with an electric motor installed outside the cylinder body. Safety misadventures caused by a fault of the electric motor can be avoided through installing the electric motor outside the cylinder body; at the same time, the cost can be saved because an explosion-proof electric motor can not be adopted.
Description
Technical field
The utility model relates to a kind of opposite-rotary axial flow type main fan.
Background technique
At present, the drive motor of opposite-rotary axial flow type main fan all is mounted in the cylindrical shell, and this just requires drive motor must adopt permissible motor, thereby the technical requirements height simultaneously, has also increased cost, and has unsafe hidden danger simultaneously.
Summary of the invention
The purpose of this utility model provides the electric machine external opposite-rotary axial flow type main fan that a kind of cost is lower, can reduce potential safety hazard.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises and is installed in the cylindrical shell impeller 6 to revolving mutually, the installation that is sealed and matched of the inner of cylindrical shell and 5 one-tenth at air-out well head, cylindrical shell is passed in 3 one-tenth hermetic seals cooperations of major axis or air-out well head 5 connects firmly with the impeller 6 that is installed in the cylindrical shell, and the outer end of major axis 3 connects firmly with the motor 1 that is installed in the cylindrical shell outside.
The utility model can cooperate suit diffuser 7 in the outer end of cylindrical shell.Also can cooperate the outer end of suit diffuser 7 to cooperate connection retention tower 9 in the cylindrical shell outer end, major axis 3 and 9 one-tenth hermetic seals of retention tower of passing retention tower 9 cooperate.Also can establish guide plate 8 at the turning that diffuser 7 connects with retention tower 9.
The utility model also can be provided with between major axis 3 and impeller shaft and connect impeller coupling 4.Or setting connects motor coupling 2 between the transmission shaft of major axis 3 and motor 1.Or setting connects impeller coupling 4 between major axis 3 and the impeller shaft, is provided with between the transmission shaft of major axis 3 and motor 1 and connects motor coupling 2.
The beneficial effects of the utility model are: it by with motor mounting outside cylindrical shell, thereby can avoid causing consequence such as security incident because of the fault of motor, simultaneously because of can not adopting permissible motor, thereby provide cost savings.
