A centrifugal fan device with adjustable blades by Bluetooth remote control

Abstract

The invention discloses a centrifugal fan device with adjustable blades by Bluetooth remote control, which includes an outer impeller, an inner impeller, a wheel cover, a wheel disc, a thin-film parameter sensor, a blade adjustment device, an electric push rod and a Bluetooth intelligent terminal; The outer impeller includes an outer disc and an outer blade, and the inner impeller includes a wheel cover, an inner disc and an inner blade; the inner disc of the inner impeller is fixed on the shaft disc; the shape of the blades of the outer impeller and the inner impeller is a wing Type, by installing the cooperation of the inner impeller and the outer impeller, the appropriate angle of the blades of the auxiliary impeller can be adjusted according to the air volume under different working conditions, so as to realize the multi-purpose effect of the centrifugal fan and achieve stable and efficient work under non-rated working conditions The purpose is to realize remote control and self-regulation through the Bluetooth smart terminal. The advanced nature of modern technology will be integrated into people's production and life. The strong controllability and stable remote control solve the inconvenience caused by the placement location and space. question.

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
