Problems solved by technology

[0002] In the existing dust-exhausting centrifugal fans, the drive motor is generally used to drive the rotating shaft of the reduction box through the belt, and the output shaft of the reduction box is fixed with the impeller in the volute to realize the transmission operation, and the belt will be deformed after being used for a certain period of time. The tension cannot be realized between the output wheel fixed on the drive motor and the drive wheel fixed on the shaft of the reduction box, making the belt prone to slipping or even falling off. position to adjust the tension, the efficiency is low, and the driving motor needs to be disassembled and moved for reinstallation, the efficiency is quite low

Abstract

The invention discloses a dust discharge centrifugal ventilator with automatic adjusted tension. The dust discharge centrifugal ventilator comprises a volute, a motor, a rotating shaft fixed with an impeller and a bottom support, wherein the volute is fixed on the bottom support, a gear box is fixed on the bottom support, one end of an output shaft of the gear box is connected with the rotating shaft through a coupler, an input shaft of the gear box is fixedly provided with a belt wheel, a transmission wheel is fixed on an output shaft of the motor, a belt is tensioned on the belt wheel and the transmission wheel, an adjusting support frame is fixed on the top surface of a main bottom plate of the bottom support, the top surface of a top plate of the adjusting support frame is fixedly provided with a pressing adjusting motor, an output shaft of the pressing adjusting motor penetrates through the bottom surface of a top plate of the adjusting support frame and is connected with a vertical adjusting screw rod through a coupler, a vertical adjusting screw sleeve is in threaded connection with the vertical adjusting screw rod, and a lifting plate is fixed at the bottom end of the vertical adjusting screw sleeve. According to the ventilator, the pressing adjusting motor operates to realize position adjustment of a pressing roller, then the tensioning degree of the belt can be adjusted, adjusting is convenient, and the effect is good.

Description

Technical field: [0001] The invention relates to the technical field of ventilation equipment, in particular to a dust-exhausting centrifugal fan with automatic tension adjustment. Background technique: [0002] In the existing dust-exhausting centrifugal fans, the drive motor is generally used to drive the rotating shaft of the reduction box through the belt, and the output shaft of the reduction box is fixed with the impeller in the volute to realize the transmission operation, and the belt will deform after a certain period of time. Tension cannot be achieved between the output wheel fixed on the drive motor and the drive wheel fixed on the shaft of the reduction box, making the belt prone to slipping or even falling off. It is inefficient to adjust the tension by the position, and the drive motor needs to be disassembled and reinstalled, which is quite inefficient. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the p...
