Abstract

The invention discloses a supercharging energy-saving type centrifugal fan. The supercharging energy-saving type centrifugal fan comprises a fan shell and a fan impeller, and is characterized in that a plurality of flow guiding blades are uniformly distributed between the outer periphery of the fan impeller and the inner wall of the fan shell by using the axis of the fan impeller as a circle center; rotating shafts are arranged at two ends of each flow guiding blade; shaft sleeves for mounting the rotating shafts are arranged on two side plates of the fan shell; each rotating shaft is provided with a swinging rod; each swinging rod is provided with an elongated groove; a connecting ring is arranged on each side plate of the fan shell; each connecting ring is provided with a pin; and the pins correspond to the swinging rods and are sleeved in the elongated grooves. If requirements on parameters of the performance of the centrifugal fan are fixed, two ends of each flow guiding blade can be welded to the two side plates of the fan shell; the number of the flow guiding blades and the number of blades of the fan impeller are relatively prime numbers; and the flow guiding blades are arranged on the centrifugal fan, air flow of outlets of the blades of the fan impeller is distributed and guided, an effect of increasing pressure and improving efficiency is achieved, and energy conservation and environmental protection are further realized.

Description

Boosting energy-saving formula centrifugal blower
Technical field
The present invention relates on ventilation equipment, be specifically related to a kind of boosting energy-saving formula centrifugal blower.
Background technique
At present for the pressure that improves centrifugal blower, be generally that these modes can make fan efficiency reduce, and do not meet energy-conserving and environment-protective development trend by changing vane type line, improve wheel speed or carry out axial impeller series connection or multistage mode realizing.
Summary of the invention
The object of the present invention is to provide a kind of by the air-flow of impeller blade outlet being carried out to the centrifugal blower that rectification and guiding reach the boosting energy-saving that improves blower pressure and efficiency.
The technical solution that realizes the object of the invention is: boosting energy-saving formula centrifugal blower, comprise fan casing and draught fan impeller, it is characterized in that: take the axle center of draught fan impeller is the center of circle, between draught fan impeller excircle and fan casing inwall, is evenly equipped with some guide vanes.
Described guide vane two ends are provided with rotatingshaft, the biside plate of fan casing is provided with the axle sleeve of installing for rotatingshaft, swing arm is housed on rotatingshaft, swing arm is provided with long strip groove, one coupling ring is installed on the side plate of fan casing, coupling ring is provided with the pin corresponding with swing arm, and long strip groove is enclosed within on pin.
The present invention can also be welded on described guide vane two ends the biside plate of fan casing.
The quantity of the quantity of described guide vane and the blade of draught fan impeller is prime number each other.
Boosting energy-saving formula centrifugal blower of the present invention has following beneficial effect: on centrifugal blower, increase guide vane, the air-flow of the blade exit of draught fan impeller is carried out to rectification and guiding, reach the effect that improves pressure and efficiency, further realize energy-conserving and environment-protective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is elaborated;
Fig. 1 is structural representation of the present invention;
Fig. 2 is guide vane of the present invention, rotatingshaft and axle sleeve annexation decomposing schematic representation;
Embodiment
As Fig. 1, shown in Fig. 2, boosting energy-saving formula centrifugal blower, comprise fan casing 1 and draught fan impeller 2, take the axle center of draught fan impeller 2 is the center of circle, between draught fan impeller 2 excircles and fan casing 1 inwall, be evenly equipped with some guide vanes 3, guide vane 3 two ends are provided with rotatingshaft 4, the biside plate of fan casing 1 is provided with the axle sleeve 5 of installing for rotatingshaft, swing arm 6 is housed on rotatingshaft 4, swing arm 6 is provided with long strip groove 6.1, fan casing 1 is provided with one and can rotates and the established angle of all guide vanes be carried out to the synchronous coupling ring 7 of adjusting simultaneously around Pivot Point Center, coupling ring 7 is provided with the pin corresponding with swing arm 6 7.1, long strip groove 6.1 is enclosed within pin 7.1.Coupling ring 7 is when Pivot Point Center rotates, and pin 7.1 drives swing arm 6 to swing, and rotatingshaft 4 is rotated, and regulates the established angle of guide vane 3.
The quantity of the blade of the quantity of described guide vane 3 and draught fan impeller 2 is mutual prime rwmber.
The quantity of described guide vane 3 is 2~37.
The shape of described guide vane 3 is single panel type or wing blade.
If it is fixed that centrifugal blower performance parameter requires, guide vane 3 directly can be welded on the biside plate of fan casing 1.
The principle of work is: the present invention adopts after said structure, air-flow enters after impeller 2 by intake grill, after rotating pressurization, impeller 2 around to approach the direction of impeller 2 blade exit established angles, flows out at impeller, through with the concentric guide vane diversion boosting of impeller after, then concentrate and guide a fixing outlet into by fan casing 1.Air-flow, after guide vane water conservancy diversion, reduces gas and goes out the sudden change eddy current disturbance state after impeller, improves the efficiency of blower fan, improves the energy of former air-flow, further improves pressure.
