The transfer member works as a whole as follows: firstly, after the pushing member moves the columnar stemming 7 in the blanking member to the lower part of the lock 14, referring to fig. 8, the lifting cylinder 12 is started, and the lifting cylinder 12 drives the lock 14 to move downwards along a1 until the lock 14 is completely sleeved on the outer surface of the columnar stemming 7; then, referring to fig. 11, which shows a schematic view of the use state of the transfer member, it can be seen that the lock 14 is moved reversely along a2 by lifting the cylinder 12, and the lock 14 gradually pierces the outer surface of the columnar stemming 7 when gradually moving upward of the columnar stemming 7, so that the columnar stemming 7 moves upward together with the lock 14; finally, when the cylindrical stemming 7 moves to the designated height, the lifting cylinder body 12 is stopped, the electric telescopic cylinder 10 is started immediately, and the electric telescopic cylinder 10 indirectly drives the cylindrical stemming 7 to move to the next process (namely, to move to the mud inlet 1501 of the cylindrical stemming machine 15) through the delivery carrier 11.
Referring to fig. 1, a cylindrical stemming machine 15 is mounted on a lifting frame 2, the cylindrical stemming machine 15 uses a commercially available product, such as a cylindrical stemming machine 15 with a model V61EQRrZ, a mud inlet 1501 is formed above the cylindrical stemming machine 15, a mud outlet 1502 is formed on one side of the cylindrical stemming machine 15, an electric push rod 1503 is mounted on the other side of the stemming machine 15, and the electric push rod 1503 is used for extruding cylindrical stemming 7 entering the inner side of the stemming machine 15 toward the mud outlet 1502.
The stemming machine 15 works as follows: after the columnar stemming 7 is placed into the stemming inlet 1501 of the stemming machine 15 by the transferring component, the electric pushing bar 1503 on the stemming machine 15 is started, so that the columnar stemming 7 is ejected from the stemming outlet 1502, the ejected columnar stemming 7 seals the iron notch 19 where the iron ejection is finished (note: before the columnar stemming 7 is extruded by the electric pushing bar 1503, the columnar stemming 7 needs to be showered and softened).
According to the invention, by combining with the stemming filling mechanism, the columnar stemming 7 is transported and filled in a mechanical and automatic mode instead of a manual mode, and the blanking, pushing, transferring and discharging are integrally designed, so that the technical problem of how to fill the columnar stemming 7 into the stemming machine 15 is effectively solved, the labor intensity of staff is reduced, and the injury of the staff is avoided to the greatest extent.

The overall workflow of the molten iron alloy smelting system is as follows: firstly, a furnace tapping machine (JC-3 type) is used for opening a tap hole 19, molten iron 25 and waste slag 26 flow out of the tap hole 19 into a tapping runner 20, and as the weight of the molten iron 25 is larger than that of the waste slag 26, as shown in FIG. 13, a schematic diagram of the distribution of the molten iron 25 and the waste slag 26 is shown, and as can be seen from the figure, the waste slag 26 is positioned above the molten iron 25; when the molten iron 25 and the slag 26 flow through the skimmer 22, the slag 26 with a relatively light weight is blocked by the skimmer 22, and then the slag 26 flows away from the slag runner 21 (along the direction e 2) which is higher than the bottom of the tapping runner 20, and the molten iron 25 with a relatively heavy weight directly flows into the tapping runner 20 (along the direction e 1) on the other side of the skimmer 22 through the skimmer 22. Then, after waiting for the single tapping to be completed (tapping time is about 20 minutes to 30 minutes), referring to fig. 14, a schematic diagram of the use of the stemming filling mechanism is shown, it can be seen from the figure that the stemming filling mechanism is rotated (along the direction a) by the driving motor 18, the stemming outlet 1502 is opposite to the tap hole 19, the columnar stemming 7 of the stemming outlet 1502 is rapidly ejected and then is injected into the tap hole 19, thereby forming a seal for the tap hole 19, completing the hole plugging, and the single tapping task is completed.
After the columnar stemming 7 is filled in the stemming filling mechanism, before the columnar stemming 7 is ejected from the stemming outlet 1502, the surface of the columnar stemming 7 needs to be sprinkled and softened, so the invention further designs an automatic water spraying mechanism, and the specific structure is as follows.
Referring to fig. 15, there is shown a schematic diagram of an installation structure of an automatic water spraying mechanism and a mud inlet 1501, and as can be seen from the figure, the automatic water spraying mechanism is divided into two parts of a water spraying unit 23 and a starting unit 24, wherein the starting unit 24 comprises a cover plate 2401, the cover plate 2401 is rotatably connected with the upper edge of the mud inlet 1501 through a hinge, gears 2402 are concentrically connected to the left and right end edges of the hinge respectively, and sliding sleeves 2404 are connected to the left and right side surfaces of the mud inlet 1501 respectively; a toothed plate 2405 is arranged on one side of the mud inlet 1501 opposite to the gear 2402, tooth parts of the toothed plate 2405 are meshed with the adjacent side gear 2402 to form linkage, an extension part of the toothed plate 2405 is in sliding connection with a sliding sleeve 2404 on the adjacent side, and a baffle 2403 is connected on the extension part of the toothed plate 2405; the sliding sleeve 2404 is connected with a spring, and the other end of the spring is connected with an extension part of the toothed plate 2405; a pressing member is connected to the surface of the cover plate 2401 opposite to the mud inlet 1501, the pressing member is composed of a support body 2406 and a pressing body 2407, the support body 2406 is connected to the cover plate 2401, and the pressing body 2407 is arranged at one side of the free end of the support body 2406; one side edge of the pressing body 2407 is connected with the edge of the supporting body 2406 through a torsion spring, and the other side edge of the pressing body 2407 is propped against the adjacent surface of the supporting body 2406, so that the pressing body 2407 can only turn over towards one end far away from the supporting body 2406. A sprinkler unit 23 is installed inside the sludge inlet 1501, and a specific structure of the sprinkler unit 23 is as follows.
Referring to fig. 15 and 16, fig. 16 shows a schematic partial structure of installation of a sprinkler unit 23, where the sprinkler unit 23 includes a placement plate 2301, the placement plate 2301 is installed on one side of a mud inlet 1501, a plurality of cavities are formed on the placement plate 2301, a spray head 2302 is disposed in each cavity, each spray head 2302 is connected with a water pipe 2303, the other end of the water pipe 2303 is connected with a water pump, and the water pump is placed in a pool; the water pump can pump the water in the water tank into the water pipe 2303, and finally the water in the water pipe 2303 is sprayed out from the spray head 2302; the water pump and the water pool are not shown in the figure, and the water pump can be directly used for the existing products which can be purchased in the market; a suction pump start switch 2304 (model: LAY 38) is installed inside the sludge inlet 1501, and the suction pump start switch 2304 is connected to a suction pump through a cable (the cable is not shown in the drawing).
Wherein, as shown in fig. 17, the blocking body 2403 is opposed to the shipping carrier 11 of the transfer member.
The automatic water spraying mechanism works as follows:
in the first situation, referring to fig. 15, when the transferring member moves toward the mud inlet 1501 with the columnar stemming 7, the carrying carrier 11 of the transferring member gradually contacts the blocking body 2403, and as the carrying carrier 11 moves, the carrying carrier 11 pushes the blocking body 2403 to move toward the b1 direction, and the toothed plate 2405 correspondingly moves along the b1 direction under the driving of the blocking body 2403, and at the same time, the spring is deformed by stretching; while the toothed plate 2405 is meshed with the gear 2402 to rotate along the direction B, and the cover plate 2401 is also turned over along the direction B under the drive of the gear 2402; until the transfer member moves to just above the mud inlet 1501 with the columnar stemming 7, the opening degree between the cover plate 2401 and the upper edge of the mud inlet 1501 is at right angle (or at an obtuse angle); at this time, the pressing member is out of contact with the suction pump start switch 2304.
In the second case, when the transfer member moves the cylindrical stemming 7 into the stemming inlet 1501, the transfer member returns to the initial position in the opposite direction (i.e., direction b 2), the carrier 11 is gradually separated from contact with the stopper 2403, and the spring returns to its original position (shrinkage deformation) under the action of its own deformation; so that the toothed plate 2405 is reset under the drive of the spring, the gear 2402 and the cover plate 2401 are reset synchronously along the reverse direction until the cover plate 2401 completely covers the mud inlet 1501, and referring to fig. 17, a state diagram of the cover plate 2401 completely covering the mud inlet 1501 is shown; meanwhile, in the process of covering the mud inlet 1501 with the cover plate 2401, referring to fig. 18, a state diagram of connection between the pressing member and the water pump starting switch 2304 is shown, and it can be seen from the diagram that the bottom of the pressing body 2407 of the pressing member gradually abuts against the water pump starting switch 2304 until the pressing body 2407 completely passes through the water pump starting switch 2304, and the water pump starting switch 2304 is in an on state (herein, the on time of the water pump can be set in the controller, for example, the on time of the water pump is set to 1min, and the controller uses the conventional technology commonly found in the market, which is not repeated here). Note that, when the opening angle of the cover plate 2401 and the mud inlet 1501 is gradually increased, the top of the pressing body 2407 is first contacted with the suction pump start switch 2304; at this time, it is defined that: the torsion spring force of the pressing member is smaller than the pressure required when the suction pump starting switch 2304 is pressed; thus, when the pressing body 2407 passes under the suction pump start switch 2304, the pressing body 2407 is turned in the f direction, and the suction pump start switch 2304 is not pressed to be turned on.
According to the invention, by combining the automatic water spraying mechanism, when the columnar stemming 7 is placed into the stemming inlet 1501 by the transferring member, the cover plate 2401 on the stemming inlet 1501 can be synchronously linked to be automatically opened; when the transferring member puts down the columnar stemming 7 to be far away from the stemming inlet 1501, the cover plate 2401 on the stemming inlet 1501 is automatically closed, and the water pump starting switch 2304 of the sprinkling unit 23 is pressed by the pressing component of the starting unit 24, so that the water pump is started, and finally, sprinkling softening operation is realized on the surface of the columnar stemming 7.
