Abstract
The invention discloses a method for controlling the speed of an elevating belt of a feeder and a material conveying system. The method for controlling the speed of the elevating belt of the feeder is applied to the material conveying system; the following functional relation between the driving frequency of a frequency converter of the elevating belt and the speed of an electronic belt scale is formed, namely, the frequency of the frequency converter f=kv=50(Hz)/the maximum speed of the belt scale (v). The method for controlling the speed of the elevating belt of the feeder performs self-adaptive control on the speed of the elevating belt of the feeder, so the original on-off running of the running mode of the elevating belt is replaced by uniform-speed or micro-variable-speed continuous running. Therefore, the problems of short device service life, high energy consumption, easy material breaking, easy blocking of a gauge pipe, troublesome operation and the like due to frequent startup and stop of the elevating belt of the feeder are solved.

Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
Embodiment one
The present invention is by improving existing materiel delivery system, do not changing under the original hardware configuration prerequisite, control algolithm by the advanced person: allow the speed of elevator belt adapt to the variation of belted electronic balance flow automatically, and make the material level of gauge line remain at gauge line meta photoelectric tube position on the upper side.
The present invention discloses a kind of feeding machine hoisting belt speed control method, is applied to materiel delivery system; Can consult Fig. 1, this materiel delivery system comprises feeding machine, elevating belt of feeder, gauge line, belted electronic balance; Gauge line and feeding machine are installed in the front of belted electronic balance, and elevating belt of feeder is positioned at feeding machine; Described gauge line comprises first identification element (the first photoelectric tube L1), second identification element (the second photoelectric tube L2), and described first identification element is positioned at the below of second identification element.
See also Fig. 3, the inventive method forms following funtcional relationship to the speed of the driving frequency of elevator belt frequency converter and belted electronic balance:
The frequency of described frequency converter
Wherein, v is the speed (m/min) of belted electronic balance.
Adopt belted electronic balance speed to calculate the driving frequency of elevator belt, its effect is better than and adopts the belted electronic balance flow.This is that its density changes thereupon because the material water ratio that is transferred changes, and when gauge line remained unchanged volume of material on the belted electronic balance, variation had also taken place the weight on the belted electronic balance, and the belted electronic balance flow formula is as follows:
Q=3600 * q * v (is v=Q/ (3600 * q)); Wherein, Q is belted electronic balance flow (kg/h), and q is the weight of material (kg/m) of belted electronic balance unit length.
By following formula as can be known, when weight of material q changed, belted electronic balance just must change speed v for keeping flow Q constant.Therefore after the flow of belted electronic balance was determined, the speed of belted electronic balance changed with material density.
As the flow that adopts belted electronic balance calculates the driving frequency of elevator belt, when material density diminishes, belted electronic balance keeps delivery rate constant by pushing the speed, and be exactly a constant by the elevator belt driving frequency that flow Q calculates, the actual flow of elevator belt is to have diminished like this, otherwise then become big, thereby caused the transport capacity between elevator belt and the belted electronic balance not match.
As the speed that adopts belted electronic balance is calculated the driving frequency of elevator belt, when material density changes, belted electronic balance can keep delivery rate constant by governing speed, the speed of elevator belt also changes thereupon like this, thereby makes the transport capacity between elevator belt and the belted electronic balance obtain coupling.
In addition, theoretical low speed and actual low speed have an error, though error is little, but long error accumulation working time one still can cause the material level of gauge line to exceed high-order photoelectric tube L 3 or be lower than meta photoelectric tube L2, therefore also need the slope k value of elevator belt driving frequency is dynamically revised, this is second a key Design thought of elevator belt adaptive control, computing formula as shown in the formula:
f＝F×k×v
＝k
n×v
Wherein, f is an elevator belt frequency converter driving frequency, and F is a k value correction factor, and k is a slope, and v is the speed of belted electronic balance, and kn is new slope.
The initial value of F can be set, as is 1.When the L2 conducting, the F value increases, and the F value reduces when L 3 ends, and the transport capacity between elevating belt of feeder and the belted electronic balance is complementary.The amplitude of the each increase and decrease of F is little, and control accuracy is just high.
More than disclosed feeding machine hoisting belt speed control method of the present invention, the present invention also discloses a kind of materiel delivery system that utilizes above-mentioned control method when disclosing above-mentioned control method.This materiel delivery system comprises feeding machine, elevating belt of feeder, gauge line, belted electronic balance; Gauge line and feeding machine are installed in the front of belted electronic balance, and elevating belt of feeder is positioned at feeding machine; Described gauge line comprises first identification element, second identification element, and described first identification element is positioned at the below of second identification element.Described system comprises elevator belt frequency adjustment unit, in order to regulate the frequency of elevator belt, makes the driving frequency of elevator belt frequency converter and the speed of belted electronic balance form following funtcional relationship:
The frequency of described frequency converter
Wherein, v is the speed of belted electronic balance, and v=Q/ (3600 * q); Q is the belted electronic balance flow, and q is the weight of material of belted electronic balance unit length.
The error that may exist for revised theory low speed and actual low speed, preferably, the frequency of described frequency converter
Wherein, F is a k value correction factor.
When the first identification element conducting, the F value increases, and the F value reduces when second identification element ends, and the transport capacity between elevating belt of feeder and the belted electronic balance is complementary.The amplitude of the each increase and decrease of F is less.
In sum, the feeding machine hoisting belt speed control method that the present invention proposes, speed to elevating belt of feeder is carried out adaptive control, make the elevator belt operational mode become the continuous operation of " at the uniform velocity " or " the little change of speed ", solved that the service life of equipment that the elevating belt of feeder frequent start-stop causes is short, energy consumption is high, material rough broken, problems such as gauge line easily stops up, troublesome poeration easily by original " switching regulator operation ".
Here description of the invention and application is illustrative, is not to want with scope restriction of the present invention in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present invention or essential characteristic, and the present invention can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the scope of the invention and spirit, can carry out other distortion and change here to disclosed embodiment.
