Abstract
The invention discloses a solid material conveying device capable of preventing a belt from tension fracture. The device comprises a belt (4), a head wheel (3), a head wheel motor (2), a head wheel controller (1) and a tail wheel (6), wherein the head wheel motor (2) drives the belt to convey materials under the control of the head wheel controller (1); and the device also comprises a sensor (5) for detecting whether the belt stops conveying. The sensor (5) is arranged on the tail wheel (6). When conveying stop of the belt is detected, the head wheel controller emits an alarm signal. The conveying device eliminates the possibility of tension fracture of the belt, improves the maintenance rate of the equipment, and can greatly reduce the investment of manpower and material resources.
Description
Technical field
The invention belongs to automation field, particularly relate to and carry out in the solid material conveying device that belt is anti-breaks control.
Background technology
In modern production technology, more and more higher to the service efficiency and the safety method requirement of equipment.Should keep the equipment oepration at full load, guarantee the device security trouble free again.This just requires this equipment to have a cover perfect automatic control system.
In the solid material pipelines transport systems, solid material will carry out anh work when being delivered to terminal point.Solid material after the dehydration is transported to the field of employment by adhesive tape conveyor.The solid material that can occur in this process on the adhesive tape conveyor can stop the adhesive tape pressure more for a long time, and the driving device of adhesive tape conveyor is also in the situation that continues operation.If this moment, operating personal failed in time to find situation, adhesive tape will be broken, thereby causes the accident.
Summary of the invention
The object of the present invention is to provide a kind of solid material conveying device that can prevent that belt from breaking, can solve the problem that adhesive tape is broken easily.
The present invention specifically discloses a kind of solid material conveying device, comprise belt, great wheel, great wheel motor, great wheel controller and tail wheel, the great wheel motor drives belt transmission material under the control of great wheel controller, also comprise a sensor, is used to detect belt and whether stops transmission.
Sensor is installed in the tail wheel place, receives the CRANK PULSES of tail wheel in real time, and signal is sent to the great wheel controller by cable.
When the situation that belt do not transmit occurring, sensor received only the signal that is once sent by tail wheel in 10 seconds, or sensor did not receive the signal that is sent by tail wheel in 10 seconds, sensor is sent to the great wheel controller with this signal by cable, great wheel controller output danger signal, the control head turbin generator quits work.
When detecting belt and stop to transmit, the great wheel controller sends alerting signal.
Described sensor can be selected NJ20+UI+W type sensor.
The present invention compared with prior art has following beneficial effect:
1) eliminated the possibility that belt is broken fully.
2) improved the maintenance rate of equipment.
3) reduced the input of manpower and materials in a large number.
Description of drawings
Fig. 1: solid material conveying device scheme drawing of the present invention.
The specific embodiment
Below in conjunction with Fig. 1, the present invention will be further described.
Solid material conveying device of the present invention has been shown among Fig. 1, and comprising belt 4, great wheel 3, great wheel motor 2, great wheel controller 1 and tail wheel 6, great wheel motor 2 drives belt 4 transmission materials under the control of great wheel controller 1.6 places are equipped with sensor 5 at tail wheel, and this sensor 5 can be selected NJ20+UI+W type sensor, and such sensor has long service life, and working environment is required low, highly sensitive advantage.Sensor 5 receives the tail wheel CRANK PULSES in real time.
When transporting just often, sensor received the analog signal that is once sent by tail wheel 6 in per 1 to 2 second.Sensor 5 is sent to the great wheel control housing by cable after this signal is converted to current signal, and it is normal that the great wheel control housing detects signal, continues the control head turbin generator and drives great wheel work.
When the situation that belt do not transmit occurring owing to material is too heavy, at this moment two kinds of phenomenons are arranged, first: sensor 5 receives the signal that tail wheel 6 sends always, and this signal is a no wait time in the middle of the continuous signal.Second: sensor 5 does not receive the signal that tail wheel 6 sends always.Sensor 5 is sent to great wheel controller 1 by cable after these two kinds of signals are converted to electric signal then.When great wheel controller 1 receives the signal that expression belt that sensor 5 sends here stops to transport, turnover detects to be judged, when sensor 5 received only the signal that is once sent by tail wheel 6 in 10 seconds, or sensor 5 is not when receiving the signal that is sent by tail wheel 6 in 10 seconds, the outputting parking signal, the control head turbin generator stops, and sends alerting signal simultaneously.
