Embodiment Construction

[0014] The main feature of the present invention is a super-large industrial ventilation and exhaust equipment, whose main function is completely different from the common ventilation and exhaust equipment in the market today. The maximum length of the fan blades of the present invention can reach about 3.5 meters. When it is placed under the beam of a large workplace, its effective ventilation area can reach tens of meters below, so using one fan can effectively solve the problem of ventilation and cooling in a workplace of 450-600 square meters. The upper end of the present invention adopts a steel fixing member 6 to be fixed with the crossbeam of the building or the I-shaped structural beam of the steel structure factory building, and the fan motor 4 is vertically fixed in the open motor fixing seat 5 downwards, and the upper end of the fixing seat is connected with the hanging frame. The rigid fixed components for hanging are closely connected together, the lower end is con...

Abstract

The invention discloses a large-size variable-frequency energy-saving fan, which is mainly used for ventilating and cooling at places such as industrial and mining enterprises, large commercial buildings, professional livestock culturing farms and the like. The ventilation and air exhaust requirements of a region which is about 450 to 600 square meters are effectively met through a variable-frequency speed regulating fan which is arranged on the top of the upper end of a building and has blades with maximum working radiuses of up to about 3.5 meters. The fan takes a variable-frequency motor of which the power is 1,500Kw as a power source, and the motor is connected with a fan blade system through a speed reducing device. A control system adopts advanced variable-frequency control, and an appropriate rotating speed can be regulated automatically and accurately according to air temperature and indoor situation.

Description

(1) Technical field [0001] The invention relates to a large frequency conversion control energy-saving fan, in particular to the main structure and technical performance of the fan. (2) Background technology [0002] Many industrial and mining enterprises, large-scale commercial buildings and professional animal husbandry farms often need ventilation and cooling through exhaust facilities due to the working environment and operational needs. At present, there are many ventilation and exhaust facilities suitable for such occasions on the market. There are relatively common exhaust fans, ceiling fans, axial flow fans and air coolers, etc., but due to the limitations of these ventilation and exhaust equipment, a workplace (for example, 450-600 square meters) often needs about 12 sets Ordinary exhaust equipment can meet the ventilation and cooling needs of personnel or equipment, which not only occupies space, but also easily causes personal injury accidents caused by clothing a...
