Description

Conveyor belt automatic meandering device {A DEVICE OF AUTOMATIC CONTROLING TENSION FOR CONVEYER BELT}

The present invention is to prevent the belt from being struck or biased from the center point due to the wear and sticking of the conveyor belt that transports the waste in the steelmaking production equipment. In particular, the maximum tension of the belt is automatically set by using the power of the motor. The present invention relates to a device that improves work efficiency and stops equipment by generating an alarm signal when the belt is excessively worn or detached.

Dust produced in steel making facilities is collected by collecting dust, and the dust contained in the water quality is precipitated in the water collection tank, and the waste (sludge cake, sludge) produced by compressing and dehydrating the precipitated and concentrated sludge in a filter press. The cake is transported using a conveyor belt.

Conveyer as described above is a belt (Belt) wear and waste or raw material stuck to the belt or roller (Roller) by the conveyor belt loses the center point and is biased or torn to one side to drop the waste or premature wear of the belt And there is a problem that causes damage, environmental pollution of the surrounding by the dropped waste or raw materials.

Therefore, it is necessary to reduce the work for collecting the dropped waste, increase the transportation capacity, and increase the service life and the operation rate of the belt by preventing premature aging of the belt and preventing the waste or raw material to be transported.

Hereinafter, a conveyor belt transport apparatus according to the prior art will be described with reference to the accompanying drawings.

Attached to explain the prior art, Figure 1 is a configuration of a conveyor belt device according to the prior art.

In general, when the belt loses its center point and is driven to one side in the process of transporting waste and raw materials from the ground to the hopper of high place by using a belt conveyor, that is, the edge of the biased belt ) Premature wear and tearing occur.

To prevent this, the meander of a belt conveyor that has been pulled or twisted to one side is manually adjusted by the operator using a tool.

Referring to the attached conveyor belt according to the prior art with reference to Figure 1, the sludge cake or cake generated by dewatering the sludge (Sludge) generated by the waste water treatment in the steelmaking production equipment by a belt conveyor (1 If the belt is shifted to one side out of the center of the upper roller (2), the edge of the belt is worn out at the same time and the printing occurs.

In order to correct the bias of the belt as described above, the operator checks the belt from time to time to adjust by using the meander adjustment bar (A-5), the nut (A-6) of the meander adjustment bar (A-5) is If it is difficult to adjust due to foreign substances and corrosion, and the belt is biased to one side too much, the body (A-3) holding the pulley of the roller support (A-2) is detached, which causes the operation rate of the equipment to drop. Waste and raw materials, etc., due to twisting will fall to the bottom causing environmental pollution.

In order to clean up the obstacles as described above, inefficient work by the worker is made continuously and from time to time, as the worker accumulates fatigue as the worker, there is a problem that the risk of a safety accident is exposed to the rotating body.

In addition, since it depends entirely on the manual work of the operator, there is a problem that can not take accurate and prompt action immediately when necessary, and is not efficient.

The object of the present invention is to automatically detect the meandering caused by the belt twist of the belt conveyor, so that the adjustment can be made quickly and safely so as to improve the transfer capacity.

The present invention devised to achieve the above object is a belt meander automatic adjustment device of the belt conveyor; Left and right detectors located on the left and right sides of the belt to detect the tension and distortion of the belt in four stages by a plurality of cam limit switches and detection sensors, and output corresponding control signals respectively and display the detection results on the operation screen. Wow; A sensor box which detects and outputs whether the belt tension and twist adjustment exceed a certain level to protect the life of the belt; A meandering adjusting unit which receives a control signal generated by processing signals output from the left and right sensing units and automatically adjusts tension and distortion of the belt by using a motor, a clutch, and a reduction gear; A washing unit which receives a control signal generated by processing signals output from the left and right sensing units and performs high pressure water washing and high pressure air washing on the lower part of the belt; A first control device receiving control signals from the left and right detection units and outputting a corresponding control signal to the washing unit to remove foreign substances attached to the lower part of the belt; And a second control device receiving control signals from the left and right sensing units and outputting control signals to the meandering control unit to correct tension and distortion of the belt.
