Summary of the invention
The object of the present invention is to provide a kind of metering corrective system and method, can calibrate the weigher on the adhesive tape conveyor, to obtain continuous data comparatively accurately.
The present invention specifically discloses a kind of metering corrective system of adhesive tape conveyor, described adhesive tape conveyor comprises an adhesive tape and No. two adhesive tapes, end at No. two adhesive tapes is provided with dump car, No. two adhesive tape is provided with the adhesive tape weigher, wherein the Sensor section of adhesive tape weigher is installed in the stage casing of No. two adhesive tapes, the display part of adhesive tape weigher is installed in the Central Control Room scale, it is characterized in that: in the dump car funnel, be provided with static scale, the adhesive tape weigher proofreaied and correct by the material of fixed amount is weighed.
During the adhesive tape conveyor normal transport, the feed bin of static scale is in open mode, and material can pass the feed bin of static scale, falls the stock ground from No. two adhesive tapes.
When calibration adhesive tape weigher, the feed bin of static scale is in closed condition, and static scale is weighed to the material of fixed amount.
The invention also discloses the method that adopts above-mentioned metering corrective system to proofread and correct, concrete steps are:
Material by adhesive tape conveyor transportation fixed amount;
After material is weighed through the adhesive tape weigher, the weight of material that shows on the record adhesive tape weigher;
After treating that material all falls into the feed bin of static scale, the weight that weighs up this partial material with the static scale line item of going forward side by side;
The weight that weighs up with static scale is standard, and the adhesive tape weigher is calibrated.
After static scale is weighed end, open the feed bin of static scale, material is fallen the stock ground.
The material of described fixed amount is with reference to the weighing capacity of static scale, in the maximum capacity scope of static scale.
The beneficial effect that the present invention is specific as follows:
1, utilize the material on the adhesive tape conveyor that the weigher that is installed on the adhesive tape conveyor is calibrated easily.
2, effectively shorten the alignment time.
3, improve the measuring accuracy and the reliability of weigher.
4, the precision data of adhesive tape weigher is that the job placement of company has a positive effect, for company is creating invisible value.
Embodiment
Specifically describe below in conjunction with the accompanying drawing documents.
Dehydrating station utilizes two adhesive tapes to carry out concentrate and carries, No. two adhesive tapes 1 are transported to material in the terminus of dehydrating station---stock ground 4, on No. two adhesive tapes 1, adhesive tape weigher 5 is installed, it specifically is the stage casing that the Sensor section of weigher 5 is installed in No. two sealing-tape machines, be convenient record weighing data, the display part of weigher is installed in Central Control Room, hangs in adhesive tape dump car funnel 3 a static scale 2 is installed.
During normal transport, the feed bin of static scale 2 is in open mode, and material can freely pass the feed bin of static scale 2, falls stock ground 4 from No. two adhesive tapes 1, guarantees that transportation is smooth and easy.
When needing calibration adhesive tape weigher 5, close the feed bin of static scale 2, thereby make the not discharging of charging of this feed bin.With reference to the maximum weighing amount of static scale 2, in static state claims 3 maximum capacity scope, by the material of adhesive tape conveyor transportation fixed amount.After the material that is used to calibrate adhesive tape weigher 5 is weighed through adhesive tape weigher 5, write down the weight of material that shows on the adhesive tape weigher 4, then after material all falls into the feed bin of static scale 2, static scale 2 is weighed up the weight of this partial material and noted.Open the feed bin of static scale 2 after static scale 2 is weighed and finished, material is fallen in the stock ground, finishes conveying.The last weight that weighs up with static scale 2 is standard, and the adhesive tape weigher 5 on No. two adhesive tapes 1 is calibrated.
