Centrifugal fan device remotely controlled with Bluetooth and with blades adjustable

Abstract

The invention discloses a centrifugal fan device remotely controlled with the Bluetooth and with blades adjustable. The centrifugal fan device comprises an outer impeller, an inner impeller, an impeller cover, impeller discs, a film type parameter sensor, a blade adjusting device, an electric push rod and a Bluetooth intelligent terminal; the outer impeller comprises an outer impeller disc and outer blades, and the inner impeller comprises the impeller cover, an inner impeller disc and inner blades; the inner impeller disc of the inner impeller is fixed to a shaft disc; the blades of the outer impeller and the inner impeller are in wing shapes respectively, through cooperation of the inner impeller and the outer impeller, the proper angle of auxiliary impeller blades can be adjusted according to the air volume under different working conditions, the effect of multiple purposes of a centrifugal fan is achieved, the purpose that the centrifugal fan device can still work stably and efficiently under the off-rating condition is achieved, remote control and automated adjustment are achieved through the Bluetooth intelligent terminal, advancement of modern technology will be undoubtedly integrated into production and life of people, and the problem of inconvenience brought by arrangement positions and space is solved through remote control with high controllability and stability.

Description

technical field [0001] The invention belongs to the field of centrifugal fan equipment, and in particular relates to a centrifugal fan device with adjustable blades by Bluetooth remote control. Background technique [0002] With the development of modern science and technology, fans, as a very common mechanical equipment in production and life, are increasingly valued by industrial production. The increase in the use of fans also means that there will be higher requirements for fans. At present, my country's energy situation combined with the current situation, energy saving and consumption reduction, and the concept of one machine with multiple functions will be the development direction of fans in the future; as far as the working conditions of fans in daily industry are concerned, there are still many unnecessary losses, which are far from meeting the economical and performance requirements. Cost expenditure, the improvement of fan is imperative for this reason. [0003] T...

AI Technical Summary

Problems solved by technology

During the working process of the centrifugal fan, the secondary flow phenomenon is often caused by the pressure difference or the pressure of the wheel disc is greater than the pressure of the wheel cover. In addition, there will be problems such as separation, vortex, shedding and wake; Due to the increased frictional resistance on the surface of the blade, the relative velocity near the suction surface is low, the relative velocity near the pressure surface is high, and the air velocity distribution is uneven; in such a complex environment, the centrifugal fan will inevitably produce gas flow loss and efficiency decline Intuitive and unfavorable phenomena such as noise and noise; these problems are concentrated on the impeller blade parts, and their quality will directly affect the working efficiency of the fan

[0004] Now there are many types of fans on the market, and the application places are also different, such as workshops, chemical laboratories, shopping malls, residential buildings and industrial buildings, etc.; with the development of population activities and industrial buildings, the air volume of most places changes within a wide range. When a similar situation occurs, in many cases due to space and economic constraints, it cannot be completely improved in a short period of time; the diversity of application places also leads to the inability to mass-produce fans under rated conditions. Influenced by many factors The working efficiency and cost performance of the centrifugal fan are seriously reduced
