Abstract
The utility model discloses a mixed-flow fan. The existing mixed-flow fan has a longer casing, can not be assembled conveniently owning to compact service environmental position, and is difficult to achieve the system design effect in certain special situations as the static pressure at the same air quantity working point is low. The mixed-flow fan is characterized in that a hub is arranged in the left end of a conical casing; a plurality of blades are arranged on the hub; an internal conical cylinder is arranged in the right end of the casing; a guide vane is arranged between the external wall of the internal conical cylinder and the internal wall of the casing; a motor is fixedly connected in the internal conical cylinder by a motor bracket; and the hub is connected on the output shaft of the motor. The mixed-flow fan has a compacter structure integrally, can be assembled more conveniently, and has good pneumatic performance and other excellent performances of high efficiency, saving energy, low noise and the like.
Description
Technical field
The utility model relates to the ventilation equipment field, specifically a kind of oblique flow ventilator.
Background technique
The casing of existing oblique flow ventilator is longer, and at work owing to the compact inconvenience in Environmental Conditions position is installed, and the static pressure of its same air quantity operation point is on the low side in the work, is difficult to reach the system design effect at some special occasions.
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 provides a kind of pressure height, air quantity big, and the oblique flow ventilator that structure is more compact, installation is more convenient.
For this reason, the technical solution adopted in the utility model is: a kind of oblique flow ventilator, comprise conical casing, the built-in wheel hub of left end that it is characterized in that described casing, the multi-disc blade is housed on this wheel hub, and the right-hand member of casing is built-in with an inner conical-tube, is provided with stator between described inner conical-tube outer wall and the casing inner wall, one motor is fixedly connected in the inner conical-tube by electric machine support, and described wheel hub is connected on the output shaft of motor.
The utility model structural design satisfies the requirement of Environmental Conditions, and its overall structure is more compact, installs more conveniently, and under the situation of identical performance parameter, volume is all less than axial flow or centrifugal blower.
It is conical that above-mentioned oblique flow ventilator, wheel hub are, and its conical surface and wheel hub shaft axis angulation α are 12～40 degree; Blade is for circumferentially being sweepforward shape, the axial sweeping curved shape structure of plunderring; Gap between casing and each blade is even; The number of blade on the wheel hub conical surface is 4～9.The impeller that above-mentioned structure constitutes blade and wheel hub has better aeroperformance effect.
Overall structure of the present utility model is more compact, installs more conveniently, is reaching under the situation of identical performance parameter, and volume is all less than present other axial flows or centrifugal blower; The utility model makes wheel hub and blade be the oblique flow meridian and quickens to be connected, and pressure is with plane No. axial-flow blower height, and air quantity is than big with the plane No. centrifugal blower, has that aeroperformance is good, efficient is high, efficiently distinguish excellent properties such as wide, energy-conservation, that noise is low.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
