Abstract
The utility model belongs to the technical field of fans, and particularly discloses a double-air-outlet ring spun yarn cotton suction centrifugal fan, which comprises an impeller and a volute. The impeller is provided with a front disk; outer profiles of the volute are logarithmic spirals; a front lateral plate and a rear lateral plate are correspondingly arranged in the front and on the back of the volute; and symmetric double air outlets with the same airflow direction are arranged on the volute. The centrifugal fan is less in pressure loss, low in energy consumption, high in operational efficiency, simple in manufacturing process and low in manufacturing cost during operation.
Description
Technical field
The utility model belongs to ventilate uses the impeller product technical field, is specifically related to a kind of pair of air-out ring spun yarn and inhales cotton centrifugal blower.
Background technique
In the prior art, ring spun yarn is inhaled cotton centrifugal blower, and its structure all adopts no shroud, no worm frame, and the blower pressure loss of this kind structural type is big, and energy consumption is big, and operational efficiency is low.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of pair of air-out ring spun yarn to inhale cotton centrifugal blower, and this centrifugal blower blower fan pressure loss in running is little, and energy consumption is low, the operational efficiency height, and preparation process is simple, and fabricating cost is cheap.
In order to realize above-mentioned technical purpose, the utility model is realized by following technological scheme:
Described in the utility model pair of air-out ring spun yarn inhaled cotton centrifugal blower, comprises the impeller and the spiral case that have shroud, and the outer molded lines of described spiral case is a log spiral, and the forward and backward side correspondence of described spiral case is provided with front side plate and back side panel.
As the further improvement of above-mentioned technology, described spiral case is provided with the identical and symmetrical two exhaust outlets of airflow direction.
In the utility model, the front side plate of described spiral case is provided with a circular arc intake grill that cooperates with the shroud of impeller, and the shroud of described impeller is the arc shroud.
As the further improvement of above-mentioned technology, the front side plate of described spiral case is a rectangle, and described front side plate is provided with a rectangular reinforced bulkhead.
In addition, the back side panel of described spiral case is provided with a circular inner hole that cooperates with impeller outer diameter.
Described spiral case rear end is provided with and the circular back shroud that is used to install motor.
In the utility model, the blade of described impeller is the backward wing blade structure, and the lobe numbers on the described impeller is 11 blades.And the blade exit established angle of described impeller is 50 °～60 °.
In the utility model, described impeller is formed by aluminium alloy casting.
Compared with prior art, the beneficial effects of the utility model are:
(1) described in the utility model pair of air-out ring spun yarn inhaled cotton centrifugal blower owing to impeller that has adopted to have shroud and the structure that spiral case is arranged, and spiral case is provided with the identical and symmetrical two exhaust outlets of airflow direction.During the centrifugal blower operation, impeller rotation back sucks gas by the intake grill place, through discharging spiral case by the two exhaust outlets on the spiral case respectively behind the backward wing blade shape impeller diffusion that shroud is arranged, improved the total head operational efficiency, energy consumption reduces greatly, for example: it is 2.2kw in portion that the ring spun yarn that did not have shroud and no spiral case is originally inhaled cotton centrifugal blower installed power exhausted, and appearance " low load with strong power " phenomenon causes the operational efficiency of centrifugal blower low.Have data to show, the total pressure efficiency of no shroud and no spiral case blower fan has only about 50%.Blower fan has increased shroud and spiral case has been arranged, and under air quantity and its constant situation of air horsepower, total head and total pressure efficiency are increased substantially, and total head has increased by 37%, and total pressure efficiency increases by 30%.
(2) impeller adopts cast aluminium alloy in the utility model, have do not scratch, nonclogging characteristics.
When (3) the utility model is installed, motor is installed on the back shroud, impeller is installed in electric machine main shaft, again back shroud is connected on the back side panel of spiral case, the arc intake grill of impeller shroud and the arc intake grill running-on on the front side plate are installed, and its working process is simple and convenient, and fabricating cost is cheap.
