Problems solved by technology

[0003] At present, fans are installed in places with high heat generation or poor ventilation conditions such as factories, power stations, and underground passages. During the operation of the fans, the air volume is constant and the wind direction is fixed. However, there are certain disadvantages under special working environment conditions, such as different Different places have different demand for fan air supply volume in different seasons
The existing air volume control technology has frequency conversion speed regulation technology, such as Chinese patent CN103671192A, but this frequency conversion speed regulation technology is expensive

Embodiment Construction

[0042] In the following, the present invention will be described in detail and specifically through specific examples, so as to better understand the present invention, but the following examples do not limit the scope of the present invention.

[0043] Such as Figure 2-5 As shown, the present embodiment provides a wind collector 1 with adjustable air volume, including:

[0044] The air inlet cylinder 11 is cylindrical or cone-shaped with both ends open;

[0045] The guide vanes 12 are arranged in the air inlet tube 11 and distributed radially;

[0046] The fixed support 13 is arranged concentrically with the air inlet tube 11 in the air intake tube 11, and the end of the guide vane 12 near the center of the circle is fixed on the fixed support 13, and several pieces of radial blades are installed on the fixed support 13. Evenly distributed guide vanes 12;

[0047] The adjusting device 14 is used to adjust the angle of the guide vanes 12 to adjust the air intake of the air...

Abstract

The invention provides an air collector allowing the air volume to be adjustable. The air collector comprises an air intake barrel, guide vanes, a fixing support and an adjusting device. The air intake barrel is in the shape of a cylinder or a conical cylinder with the two ends open. The guide vanes are arranged in the air intake barrel and distributed radially. The fixing support is concentric with the air intake barrel and arranged in the air intake barrel, the ends, close to the circle center, of the guide vanes are fixed to the fixing support, and the guide vanes distributed radially and evenly are mounted on the fixing support. The adjusting device is used for adjusting the angle of each guide vane so that the air intake volume of the air collector can be adjusted. According to the air collector, the air volume of the air collector can be adjusted through mechanical linkage, cost is low, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an adjustable wind collector for industrial fans. Background technique [0002] The air collector, also known as the air inlet, is generally installed at the inlet of the fan. It has arc-shaped, conical and other shapes, and is in the form of axial convergence. figure 1 A schematic diagram of the structure of a common fan is given, such as figure 1 As shown, 1 is an air collector, 2 is an impeller, 3 is a casing, and 4 is a transmission part. [0003] At present, fans are installed in places with high heat generation or poor ventilation conditions such as factories, power stations, and underground passages. During the operation of the fans, the air volume is constant and the wind direction is fixed. However, there are certain disadvantages under special working environment conditions, such as different The demand for the air supply volume of the fan is different in different seaso...
