Fan device and method for glass drying

Abstract

A fan device for glass drying comprises a fan, an air supply pipeline, an air outlet, an inductor device for detecting glass height, a motor variable frequency speed regulator for adjusting air quantity and a control device. The fan is connected with the air outlet through the air supply pipeline. The fan comprises a fan motor connected with the motor variable frequency speed regulator in a control mode. The air outlet is two long-strip-shaped holes arranged vertically in parallel and is divided into an upper air outlet and a lower air outlet according to the vertical position. An upper air outlet opening closing device used for controlling opening and closing of the upper air outlet is arranged at the position of the upper air outlet and comprises an air port baffle. The inductor device is located in front of the air outlet and comprises more than two inductors arranged from top to bottom, and the position of the inductor is matched with that of the air outlet. The inductor device, the motor variable frequency speed regulator and the upper air outlet opening closing device are connected with the control device in a control mode.

Description

technical field [0001] The invention relates to the field of glass drying, in particular to a device and method for glass drying. Background technique [0002] Glass needs to be cleaned and dried before processing. Generally, the motor of the drying system drives the fan to generate air volume, and the drying air is sent into the bellows through the air supply pipe. The slits, that is, the air knife, are blown onto the glass through the air knife to dry the glass. In the current cleaning and drying device, the supporting air knife and motor are all configured according to the maximum glass height and travel speed. In the working state, all the air knife edges are blown out, and the fan motor works at a higher speed. Take the common 2500mm washing and drying machine as an example, it is equipped with a 30kw motor, the working frequency is 50HZ, and the length of the air knife is 2600mm. However, in the actual production process, more than 60% of the glass heights are below ...

AI Technical Summary

Problems solved by technology

However, in the actual production process, more than 60% of the glass height is below 1500mm, and the wind from the upper part of the air knife has no effect, resulting in a great waste of energy

There are also manufacturers whose fans are equipped with frequency converters, just to reduce the starting load, and the effect of energy saving is not obvious
