Description
Technical field
The utility model relates to a kind of meausring apparatus, especially a kind of belt feeder weighing device that is applicable to bulk material.
Background technology
Along with the rising of bulk material prices such as coal, iron ore, more and more high to the requirement of belt feeder weighing device measuring accuracy, simultaneously reliability, the stability of its measuring accuracy are paid attention to more.Be used for the selected LOAD CELLS of the belt conveyer scale of belt feeder metering at present, himself precision of control instrument of weighing is higher, can reach more than 0.03%.And belt conveyer scale is installed on the belt feeder its service precision only at 1%---0.5%, to be belt feeder cause the influence of various factorss such as belt tension variation, vibration and can not calibrate easily with what of material on it for the often more difficult assurance of the stability of its precision, its main cause.
The calibrating mode of existing belt conveyer scale has the calibration of weight of suspension, captive chain calibration, Electronic Calibration, material calibration, remove the material calibration and can truly reflect material operation real conditions, calibrate with a high credibility, other several calibrating modes all are analog calibrations, belt tension situation in the time of can not truly reflecting batcher total length upper berth full with substance, calibration error is big, can not satisfy actual demand, and the inventory that the material calibration needs is more, it is inconvenient that material is got at the scene, be difficult to implement calibration, cause the measuring accuracy of belt feeder low.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, and a kind of simplified structure, easy to operate, calibration of weight is accurate, measuring accuracy is high, the correcting device cost is low belt feeder weighing device are provided.
For achieving the above object, belt feeder weighing device of the present utility model, comprise the first belt conveyer scale frame and the second belt conveyer scale frame that are located at interval on the belt feeder, be provided with the impact idler group that is installed on the batcher between the first belt conveyer scale frame and the second belt conveyer scale frame, impact idler group top is provided with the counterweight storehouse that there is counterweight inside, the counterweight storehouse links to each other with batcher, the batcher head is connected with counterweight and collects support, be respectively equipped with initial point detector and velometer on the batcher, the first belt conveyer scale frame, the second belt conveyer scale frame, the initial point detector, velometer is connected with by cable respectively can show that material passes through the cumulative weight of the first belt conveyer scale frame, the cumulative weight of the second belt conveyer scale frame, the control instrument of weighing at the belt zero point in one section strap length of counterweight weight that discharges in the counterweight storehouse and initial point detector measurement.
Described initial point detector is contactless or contact type probe; The described first belt conveyer scale frame and the second belt conveyer scale frame are single-idler receptor, double bracket roller scale frame or many carrying rollers scale frame.
Beneficial effect: owing to adopt initial point detector, two belt conveyer scale framves and a counterweight machine, and utilize the heavy control instrument of a table scale to realize that few counterweight substitutes the many counterweights of many materials and carries out belt conveyer scale comparison, calibration, realize the high precision weighing.Adopt less counterweight to substitute many materials or many calibration of weights, realize online operation measuring accuracy of proofreading belt conveyer scale easily easily, the correcting device cost is low, does not influence normal production during calibration, guarantees the operation measuring accuracy of belt conveyer scale.Integrate and weigh and online calibration of weight, realize that dynamic weighing and the alternative many materials of few counterweight or many counterweights carry out the calibration of belt conveyer scale, cost is low, efficient and convenient, precision is reliable, has saved great amount of manpower and material resources, guarantee the belt conveyer scale high-precision measuring, have practicality widely.
Description of drawings
Fig. 1: be apparatus structure synoptic diagram of the present utility model.
Among the figure: the 1-first belt conveyer scale frame, 2-impact idler group, 3-counterweight storehouse, the 4-second belt conveyer scale frame, 5-counterweight are collected support, 6-initial point detector, 7-weigh belt on belt under control instrument, the 8-conveyor, the 9-conveyor, 10-velometer, 11-counterweight.
Embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Belt feeder weighing device of the present utility model mainly is made of the first belt conveyer scale frame 1, impact idler group 2, counterweight storehouse 3, the second belt conveyer scale frame 4, counterweight collection support 5, initial point detector 6, the control instrument 7 of weighing, velometer 10, counterweight 11.The first belt conveyer scale frame 1 and the second belt conveyer scale frame 4 can be single-idler receptors, also can be double bracket roller scale framves, can also be many carrying rollers scale frame; Initial point detector 6 adopts contactless or contact type probe.The first belt conveyer scale frame 1, the second belt conveyer scale frame 4 is installed on the batcher at interval, under batcher on belt 8 and the batcher between the belt 9, between the first belt conveyer scale frame 1 and the second belt conveyer scale frame 4 impact idler group 2 is housed, impact idler group 2 tops are provided with counterweight storehouse 3, there is counterweight 11 in the counterweight storehouse 3, counterweight storehouse 3 links to each other with batcher, counterweight is collected support 5 and is linked to each other with the batcher head, initial point detector 6, velometer 10 is installed on the batcher, the first belt conveyer scale frame 1, the second belt conveyer scale frame 4, initial point detector 6, velometer 10 is connected with by cable respectively can show that material passes through the cumulative weight of the first belt conveyer scale frame 1, the cumulative weight of the second belt conveyer scale frame 4, counterweight weight that discharges in the counterweight storehouse 3 and initial point detector 6 are measured the control instrument 7 of weighing at the belt zero point in one section strap length.
Principle of work: when the batcher convey materials, place counterweight 11 in advance in the counterweight storehouse 3 on batcher, the control instrument 7 of weighing detects belt calibration initial point by initial point detector 6, control instrument 7 output signals of weighing control counterweight storehouse 3 discharges counterweights 11 and puts it on the conveyor on the material on the belt 9, counterweight 11 moves with material, runs to counterweight when arriving the batcher head and collects on the support 5; What this moment first, belt conveyer scale frame 1 measured is convey materials accumulating weight value, what the second belt conveyer scale frame 4 measured is the gravimetric value sum of the counterweight 11 under convey materials accumulating weight value and counterweight storehouse 3 discharge, identical based on the first belt conveyer scale frame 1 with the convey materials amount that the second belt conveyer scale frame 4 passes through, the control instrument 7 of weighing removes the cumulative weight value of the second belt conveyer scale frame, 4 weighings the cumulative weight value of the first belt conveyer scale frame, 1 weighing, obtain the actual weighing value of the counterweight 11 that counterweight storehouse 3 discharges, the gravimetric value of the counterweight 11 of this actual weighing is compared with the gravimetric value of the standard test weight 11 that control instrument 7 inside of weighing count to get, draw correction factor, make it display standard weight of material value by this correction factor correction control instrument 7 coefficient of rangers of weighing, regularly compare, correction makes the belt conveyer scale measuring accuracy reach high precision, high stable.Be covered with material on the belt feeder total length this moment, and operating mode when calibrate mode approaches normally to carry adopts few calibration of weight to replace many materials or many calibration of weights.
