Definitions

  • the invention relates to a control system for a conveyor belt driven by at least one drive or a conveyor belt device in industrial use. Overburden or raw materials can be transported by means of the conveyor belt, which is designed for an output of at least 5 tons per hour.
  • Opencast mines use raw materials such as Coal, often transported many kilometers on conveyor belts or conveyor belt devices. A lot of electrical energy is consumed during this transport. Comparable problems also arise with the long-distance transportation of raw materials and the transportation of coal or overburden underground.
  • the task is solved by a conveyor with a regulation according to claim 1.
  • the speed of the conveyor belt is set depending on the amount of overburden to be transported or the raw materials to be transported. While conveyor belts in known conveying devices are constantly driven at a speed which essentially corresponds to a speed which is necessary for a maximum conveying capacity, the speed is adapted according to the invention to the conveying flow, which reduces the need for electrical energy.
  • the control adjusts the speed of the conveyor belt so that it is full or is largely fully utilized. This operating point corresponds to an optimum in the sense that the energy saving is maximum.
  • control system has a monitoring device which is designed to monitor the conveyor belt, in particular with a timely look for overload and to prevent overload of the conveyor belt. In this way, overloading of the conveyor belt is avoided by the speed increase according to the invention. Predictive monitoring is particularly important, as it enables the conveyor belt to be accelerated in time in spite of its great inertia in order to react to peak loads in relation to the overburden to be transported or the raw materials.
  • the speed of the conveyor belt depends on the maximum value of the overburden or pipe material to be transported within a certain time interval. In this way, violent control movements in the drives and possible overload due to the inertia of the conveyor belt are prevented.
  • the time interval is advantageously greater than the time for the conveyor belt to run up to maximum speed.
  • the conveying device has at least one measuring device by means of which the amount of the raw material to be transported is measured.
  • the measurement is advantageously carried out so early that jumps in relation to the quantity of overburden or raw materials to be transported are detected in time so that the conveyor belt can be accelerated to a speed which corresponds to the new load condition.
  • controls or regulation and / or the measuring device are designed at least twice redundant, the values supplied by them are compared with each other. If these differ from each other in double redundancy, the conveyor belt is accelerated to its maximum speed. In the case of multiple redundancy, the faulty component can be identified and outsourced.
  • the conveyor device has speed-controlled drives, in particular speed-controlled three-phase motors.
  • P N is the output of the motors in kW
  • f is the STARTING severe, ie, the average starting torque
  • t A the start ⁇ time in seconds.
  • Z a is the number of starts per year.
  • Q is the flow rate, m the mass of the conveyed goods on the conveyor belt and m N the mass of the conveyed goods on the conveyor belt at nominal load.
  • P RN is the friction or flexing power at the nominal delivery rate, F R the friction and flexing force and F RN the nominal friction and flexing force.
  • the function can be approximated according to equation (6) using the following formula:
  • HN RN KP N 14
  • Equation (14) resolved according to P RN gives:
  • Equation (15) inserted in equation (12) gives:
  • the energy savings achieved with the invention are particularly great when used for opencast mining systems, since on the one hand these have a very high energy consumption and on the other hand are subject to comparatively high load fluctuations.
  • Another particularly advantageous application for the control according to the invention is represented by conveyor belts for the long-distance transport of raw materials, since these consume a particularly large amount of energy.
  • FIG. 1 shows an embodiment for the use of a control according to the invention in a conveyor with two conveyor belts
  • FIG. 2 shows the principle of operation of a belt scale working without contact.
  • the first conveyor belt 1 shows an embodiment for the use of a control according to the invention with two conveyor belts 1 and 2.
  • the first conveyor belt 1 is loaded with bulk goods by means of a loading device 3.
  • the first conveyor belt 1 transports the bulk material to a second conveyor belt 2, which in turn transported to a loading device 4.
  • the utilization of the conveyor belts 1 and 2 is measured by means of a measuring device 6.
  • These measured values are fed to a control 7 according to the invention which, by influencing the drives 5 and 8 of the conveyor belts 1 and 2, adapts the speed of the conveyor belts 1 and 2 to their capacity. If the quantity demanded is known, the measuring device 6 is not necessary.
  • the loading device 3 and the control are connected in terms of data technology.
  • the belt scale according to the invention has a full height measuring device 22 and a seal measuring device.
  • the density measuring device has a radiation source 24 and a radiation receiver 25.
  • the radiation 26 emitted by the radiation source 24 and received by the radiation receiver 25 penetrates the conveyor belt 20 and bulk material 21.
  • the full height measuring device 22 and the density measuring device are connected to an evaluation unit 23 for evaluation. However, an evaluation can also take place in the density measuring device or in the full height measuring device 22.
  • the data link between density measuring device, full height measuring device and evaluation unit 23 can be made via a bus system or via point-to-point connections.
