The conveying slide 6 is driven by a chain plate, so that automatic blanking is further enhanced.
By utilizing the iron alloy ton bag quick unpacking and unloading and the ton bag automatic compressing, packing and collecting device after unpacking and unloading, the method for quickly unpacking, packing and collecting the waste bag comprises the following steps:
transferring the ferroalloy ton bags from the stacking position to the position above the operating platform 1 through a crane hook, and simultaneously transferring vehicles to enter a bin receiving area at the bottom of the platform for waiting; after the infrared grating senses that the vehicle is in place, an induced air bag dust removal outdoor unit is started, and after a stable adsorption area is established in a negative pressure dust collection loop through a pipeline, an electric heating cutting knife 3 is started; when the temperature of the outer surface of the electric heating cutter 3 rises to more than 400 ℃, the crane transfers the iron alloy ton bag to be cut and unloaded to the supporting frame 7 of the electric heating cutter 3, the weight of the ton bag does not need to be completely borne on the supporting frame 7, and only 70% of the hoisting weight needs to be kept. Therefore, the ton bag is still in a vertical state, the bottom of the ton bag is not in line contact with the electric heating cutter 3 to slide, and smooth unloading can be ensured. Staying for a moment, the alloy ton bag is quickly broken along the cut seam under the combined action of the high-temperature heat melting of the electric heating cutter 3 and the external tension converted from the internal gravity, and the ferroalloy is unloaded into the carriage at the lower part of the operating platform 1 along with the situation, so that one-time quick unloading is completed;
in the above, since the upper end of the electric heating cutter 3 is provided with the ton bag and the lower part is provided with the alloy, most of the dust generated by bag breaking and discharging can be limited in the first negative pressure dust collecting loop 2a and absorbed away.
Under the control of the PLC, the longitudinal and transverse electric heating cutters and the adjacent electric heating cutters 3 are used at intervals of circulating power-on, so that a complete quadrilateral hot melting state is not generated, fragments are not generated to be separated from the bottom of an original ton bag, and the situation that the fragments of the plastic woven bag fall into a carriage along with iron alloy once, and subsequent steelmaking dust removal equipment is blocked and disabled is avoided.
Taking 75% ferrosilicon as an example, the size of the bottom surface of each ton of the bag is 750 x 750mm, four bags are hung in a field shape, and the section of the bottom is formed to be 1.5 x 1.5m (2.25 square meters), and the section is contacted with an electric heating cutting knife. Because of incomplete contact, the bottom convex part of each ton bag is preferentially melted by heat to break the bag, and the unloading of all the ferrosilicon alloy can be completed in about 10 seconds; according to 1000 bags of daily broken bags, the silicon-manganese alloy is hung by four bags and 1 crane and hung by eight cranes for 1 vehicle, namely, each vehicle has about 32 tons of load.
And when the lifting is finished, the operator takes the four ton bags off the lifting hook of the travelling crane at one time by using the unhooking tool. The same level of operation is maintained, i.e. it is ensured that the bottom of the unpackaged bag is smoothly transferred to the entrance of the induction tearing machine 4 above the platform rail on the operation table 1. The infrared grating at the inlet of the induction tearing machine 4 induces the waste ton bags to start the tearing machine, the loose and light bale breaking ton bags are cut into long strips while being bitten, and are forcibly pushed into the chain plate type conveying slide 6 and then are pushed into a compression cavity of the vertical automatic packaging machine 5. The operation of the induction tearing machine 4 is also in the second negative pressure dust collecting loop 2b in the whole process, so that the environment protection of the raised dust is ensured to reach the standard. Wherein, the upper end of the induction tearing machine 4 is provided with a safety cover plate, and the closing protection state is kept during the non-operation time.
During waiting for next alloy ton bag removal and lifting on the alloy ton stack by the travelling crane, the packer 5 automatically starts the compression action, and compresses the originally torn fluffy plastic woven material for 1 time; because the vertical automatic packing machine is designed into a constant pressure return way mode, namely, the pressure relief return way is realized when the compression ratio reaches 30 and is the maximum pressure point, the crushed aggregates can be ensured to be shaped without rebounding. The bag breaking process is carried out for 4 bags, and the compression process is carried out for 8 times in a circulating way. The ton of bags are compressed by about 100mm per 1 compression in the baler. Finally, completing a compressed plastic woven material cube with the height of 800mm, the thickness of 1000mm, the width of 1000mm, and the length of 800 mm; the first compression and return time is 60 seconds, the subsequent pressing and return distance and time are reduced in sequence, and the average consumed time is 35 seconds. And one lifting ton bag is lifted by the aid of the reloading crane, and the time consumed for each reciprocating operation at least exceeds 2 minutes and far exceeds the time consumed for the first compression according to different alloy stacking distances and safe operation. Under the actual condition, in order to improve the operation efficiency, the left and right matched feeding of two traveling cranes matched with each bag breaking machine can also meet the production requirements.
The vehicle transfer clearance provides the baler 5 with sufficient baling time for one bale. The baling machine 5 starts a baling mode, after four times of manual nylon strapping tape front and back strapping are carried out, the front door of the baling machine is opened, the rear push-out oil cylinder pushes out the baled plastic woven material ton bag, and the baled plastic woven material ton bag is transferred to a stacking area by a forklift. Finally, the cubic body of the compressed plastic woven material with the height of 800mm, the thickness of 1000mm, the width of 800mm and the like is finished. The time of the vehicle in transit and the steel-making side unloading is more than 30 minutes, the time for completing one-time tape threading, packaging and forklift transferring and stacking is not more than 20 minutes, and the time is sufficient.
About 1000 tons of various alloys (1000 ladles) are required to be put into the furnace every day when 900 ten thousand tons of molten steel are produced in a steel making year. When a 32-ton truck is used, 4 bags of the silicon-manganese alloy are hung for 1, and 8 bags of the silicon-manganese alloy are hung for 1 truck. And 3, 1 hoisting other lower-density alloy bags 1, and 10 hoisting 1 vehicle. The effective operation time of three shifts each day is 3 hours, namely 9 hours all day can meet the production requirement, and the effective operation rate is 37.5%. Except for a driver, 1 person in the whole bag breaking and packaging operation area can finish the work of empty bag removal, feeding, bundling, transferring and stacking.
