Compared with common belt conveyor, the tubular belt conveyor has advantages both in technology and performance. This article mainly deals with the technical features of the tubular belt conveyor.
(1) Driving device
The driving device of this belt conveyor mainly includes variable frequency motor driving and hydraulic motor driving. The former is mainly composed by the motor, reducer, coupler, frequency conversion device and driving roll. The latter provides the needed flow and pressure for the hydraulic motor relying on the power station.
(2) Tension device
The tension device of the tubular belt conveyor adopts hydraulic pressure automatic tension device or heavy hammer tension device. During the normal working process of the belt conveyor, as for the tension fluctuation of the belt caused by the changing of the conveying amount, the hydraulic pressure automatic tension device can be used for automatically adjusting the tension of the belt in order to maintain the stable tension of the belt. The heavy hammer tension device is able to use the space position of the vestibule for convenient arrangement.
(3) Emergency switch
When the belt conveyor breaks down, the workers can turn off the switch on any part of the belt conveyor, and then the machine will automatically lock and ring the alarm bell, and this conveying machine and the upstream equipment will stop working.
(4) Off tracking switch
The off track switch is installed on both sides of the belt conveyor in order to make sure that the touching roller of the switch and the contact site of the belt maintains on the 1/3 of the height of the contact roller. When the belt conveyor is off track, it can realize the function of automatic alarming and stoppage.
(5) Chute blocking device
This device is mainly used for examining whether the funnel on the head and tail of the belt conveyor and the chute are blocked. When the funnel and the chute are blocked, this device can immediately ring the alarm and statistics signal to prevent the accidents.
(6) Vertical tearing switch
This switch is installed on the bottom of the loading belt of the material receiving point on the tail part of the belt conveyor, and it is able to examine the vertical tearing fault of the belt at any time and timely give the stoppage signal in order to prevent the accident from expanding and minimizing the losses.
