Description

Technical Field

[0001] The utility model belongs to the technical field of ladle auxiliary equipment, in particular to a ladle drying device. Background Art

[0002] The ladle is a crucial piece of equipment in the foundry production process. It receives molten iron from the electric furnace and then pours the molten iron into the mold cavity. A finished ladle has a limited lifespan and must be thoroughly dried before reuse. This is extremely dangerous because hot molten iron can explode when it encounters wet materials. Therefore, it must be dried before use. Currently, most foundries still dry the ladle by placing dry firewood in it and igniting it. However, charcoal needs to be cleaned after drying. Burning firewood or coal creates residue, which weakens the heating effect at the bottom. Furthermore, if the charcoal is insufficient, the ladle must be opened to refill, resulting in heat loss and potentially burns to the operator. Utility Model Content

[0003] Based on the above background, the purpose of the present invention is to provide a ladle drying device.

[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A ladle drying device comprises a conveyor belt on which a ladle to be dried is placed;

[0006] Support frames are provided on both sides of the conveyor belt, trusses are fixed between the support frames, a cylinder is provided on the trusses, the output end of the cylinder is connected to a first sealing cover, a discharge pipe is passed through the first sealing cover, and a drying component is provided below the discharge pipe;

[0007] The drying assembly includes a charcoal basin, which is arranged below the discharge pipe and fixedly connected to the discharge pipe through a first connecting rod. A waste basin is fixedly connected to the bottom of the charcoal basin, and an iron grid is provided in the charcoal basin. The waste basin and the charcoal basin are connected through the iron grid.

[0008] An air inlet pipe and an air outlet pipe are provided through the first sealing cover, and a bellows is provided on the first sealing cover, and one end of the air inlet pipe is connected to the bellows;

[0009] The first sealing cover is provided with a humidity sensor.

[0010] Preferably, there are four first connecting rods, which are symmetrically arranged at the bottom of the discharge pipe. The first connecting rod is L-shaped and will not affect the replenishment of wood in the discharge pipe.

[0011] Preferably, a correction plate is provided under the first sealing cover, and the correction plate is frustum-shaped. The correction plate can cover the molten iron ladle with the first sealing cover so that the molten iron ladle and the first sealing cover are coaxial, thereby ensuring that the drying component is located on the coaxial line of the molten iron ladle, and the dissipated heat can evenly reach the inner periphery of the molten iron ladle.

[0012] Preferably, the bellows is sleeved on the outside of the air outlet pipe, and the air outlet pipe passes through the bellows.

[0013] Preferably, the end of the outlet pipe located above the first sealing cover is spiral-shaped, and the flue gas discharged from the outlet pipe carries heat. By arranging a bellows on the outside of the outlet pipe and the upper end of the outlet pipe is spiral-shaped, the air in the bellows can be heated, thereby increasing the air temperature input to the molten iron ladle, improving the efficiency of the drying component, and reducing the loss of heat energy.

[0014] Preferably, a pair of baffles are rotatably connected to the bottom of the discharge pipe, and the baffles can be rotated downward to open the bottom of the discharge pipe. The baffles and the discharge pipe can be connected by a hinge or a torsion spring. When charcoal is fed from the discharge pipe, the baffles are rotated downward to open due to the gravity of the charcoal. After the charcoal falls from the discharge pipe into the charcoal basin, it loses the push of gravity, and the baffles rotate upward and merge to seal the bottom of the discharge pipe, thereby preventing smoke from leaking from the discharge pipe.

[0015] Preferably, the sliding sleeve on the side of the discharge pipe is provided with a movable sleeve, and the lower end of the movable sleeve is fixedly connected to a second sealing cover;

[0016] A steel rope is fixedly connected to the top of the movable sleeve, an electric rope winding machine is provided on the top of the first sealing cover, and the other end of the steel rope passes through the first sealing cover and is fixedly connected to the electric rope winding machine.

[0017] Preferably, a sliding rod is fixedly provided on the top of the first sealing cover, and the sliding rod is slidably connected to the truss to improve the stability of the first sealing cover when moving up and down.

[0018] The utility model has the following beneficial effects:

[0019] 1. The cylinder drives the first sealing cover to move downward to cover the top of the molten iron ladle. The charcoal basin located below the first sealing cover extends into the interior of the molten iron ladle. The charcoal basin is filled with burning charcoal. The burning charcoal increases the temperature inside the molten iron ladle. The bellows transports air into the molten iron ladle through the air inlet pipe to ensure that the charcoal can be fully burned. The ashes after the charcoal is burned fall into the waste basin. The smoke in the molten iron ladle is discharged through the air outlet pipe. The outlet end of the air outlet pipe can be connected to an external flue gas treatment device to treat the smoke. If the charcoal in the charcoal basin is insufficient, it can be replenished in time through the discharge pipe. There is no need to take out the charcoal basin and then replenish charcoal. This can reduce heat loss and improve drying efficiency.

[0020] 2. By arranging the bellows on the outside of the outlet pipe and the upper end of the outlet pipe being spiral, the air in the bellows can be heated, thereby increasing the temperature of the air input to the ladle, improving the efficiency of the drying component, and reducing the loss of heat energy.

[0021] 3. After the ladle is dried, the electric rope reel unwinds, the movable sleeve slides downward along the outside of the discharge pipe, the second sealing cover covers the top of the charcoal basin, and the movable sleeve seals the connection between the discharge pipe and the charcoal basin. The charcoal basin is sealed at this time, which can reduce heat loss and avoid smoke generated by burning charcoal in the charcoal basin. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The drying assembly 4 includes a charcoal basin 42, which is arranged below the discharge pipe 31 and fixedly connected to the discharge pipe 31 via a first connecting rod 41. A waste basin 43 is fixedly connected to the bottom of the charcoal basin 42. An iron grid 44 is provided in the charcoal basin 42, and the waste basin 43 is connected to the charcoal basin 42 via the iron grid 42.

[0045] A humidity sensor 6 is provided on the first sealing cover 3 .

[0046] The conveyor belt 1 transports the ladle 9 to be dried to the bottom of the truss 12, and the cylinder 2 drives the first sealing cover 3 to move down to cover the top of the ladle 9. The charcoal basin 42 located below the first sealing cover 3 extends into the interior of the ladle 9. The charcoal basin 42 is filled with burning charcoal. The burning of charcoal increases the temperature inside the ladle 9. The bellows 5 transports air into the ladle 9 through the air inlet pipe 32 to ensure that the charcoal can be fully burned. The smoke in the ladle 1 is discharged through the air outlet pipe 33, and the air outlet end of the air outlet pipe 33 can be externally discharged. Connect the flue gas treatment equipment to treat the flue gas. If the charcoal in the charcoal basin 42 is insufficient, the charcoal can be replenished in time through the discharge pipe 31. There is no need to take out the charcoal basin 42 and then replenish the charcoal. This can reduce heat loss and improve drying efficiency. According to the measurement of the humidity sensor 6, after the drying is completed, the cylinder 2 drives the first sealing cover 3 and the drying assembly 4 to rise and remove the molten iron ladle 9, and the next molten iron ladle 9 is conveyed to the bottom of the truss 12 by the conveyor belt 1, and the above steps are repeated for drying.

[0047] Preferably, four first connecting rods 41 are provided, symmetrically arranged at the bottom of the discharge pipe 31 , and the first connecting rods 41 are L-shaped, which will not affect the feeding pipe 31 to replenish wood.

[0048] Preferably, a correction plate 34 is provided under the first sealing cover 3, and the correction plate 34 is a frustum. The correction plate 34 can cover the molten iron ladle 9 on the first sealing cover 3 so that the molten iron ladle 9 is coaxial with the first sealing cover 3, thereby ensuring that the drying component 4 is located on the coaxial line of the molten iron ladle 9, and the dissipated heat can evenly reach the inner periphery of the molten iron ladle 9.

[0049] Preferably, the bellows 5 is sleeved on the outside of the air outlet pipe 33 , and the air outlet pipe 33 passes through the bellows 5 .

[0050] Preferably, the end of the air outlet pipe 33 located above the first sealing cover 3 is spiral-shaped, and the flue gas discharged from the air outlet pipe 33 carries heat. By arranging the bellows 5 on the outside of the air outlet pipe 33 and the upper end of the air outlet pipe 33 is spiral-shaped, the air in the bellows 5 can be heated, thereby increasing the air temperature input to the molten iron ladle 9, improving the efficiency of the drying component 4, and reducing the loss of heat energy.

[0051] Preferably, a pair of baffles 35 are rotatably connected to the bottom of the discharge pipe 31. The baffles 35 can be rotated downward to open the bottom of the discharge pipe 31. The baffles 35 and the discharge pipe 31 can be connected by a hinge or a torsion spring. When charcoal is fed from the discharge pipe 31, the baffles 35 are rotated downward to open due to the gravity of the charcoal. After the charcoal falls from the discharge pipe 31 into the charcoal basin 42, it loses the push of gravity and the baffles 35 rotate upward and merge to seal the bottom of the discharge pipe 31, thereby preventing smoke from leaking from the discharge pipe 31.

[0052] Preferably, a movable sleeve 36 is provided on the side sliding sleeve of the discharge pipe 31, and a second sealing cover 37 is fixedly connected to the lower end of the movable sleeve 36;

[0053] A steel rope 38 is fixedly connected to the top of the movable sleeve 36, and an electric rope winding machine 7 is provided on the top of the first sealing cover 3. The other end of the steel rope 38 passes through the first sealing cover 3 and is fixedly connected to the electric rope winding machine 7;

[0054] After the drying of the molten iron ladle 9 is completed, the electric rope winder 7 is unwound, the movable sleeve 36 slides downward along the outer side of the discharge pipe 31, the second sealing cover 37 covers the top of the charcoal basin 42, and the movable sleeve 36 seals the connection part between the discharge pipe 31 and the charcoal basin 42. At this time, the cylinder 2 is started to drive the first sealing cover 3 and the drying component 4 to rise. The charcoal basin 42 is sealed at this time, which can not only reduce heat loss, but also avoid the combustion of charcoal in the charcoal basin 42 to produce smoke. When the molten iron ladle 9 is dried, after the first sealing cover 3 covers the molten iron ladle 9, the electric rope winder 7 is reeled in to move the movable sleeve 36 and the second sealing cover 37 upward, and the seal of the charcoal basin 42 is released to dry the molten iron ladle 9.

[0055] Preferably, a sliding rod 8 is fixedly provided on the top of the first sealing cover 3 , and the sliding rod 8 is slidably connected to the truss 12 to improve the stability of the first sealing cover 3 when moving up and down.

[0056] The working principle of the present invention is as follows: the conveyor belt 1 conveys the molten iron ladle 9 to be dried to the bottom of the truss 12, the cylinder 2 drives the first sealing cover 3 to move down, covers the top of the molten iron ladle 9, and the charcoal basin 42 located below the first sealing cover 3 extends into the interior of the molten iron ladle 9. After the electric rope winding machine 7 reels up the movable sleeve 36 and the second sealing cover 37, the seal of the charcoal basin 42 is released. The charcoal basin 42 is filled with burning charcoal. The burning of charcoal increases the internal temperature of the molten iron ladle 9, and the bellows 5 conveys air to the molten iron ladle 9 through the air inlet pipe 32 to ensure that the charcoal can be fully burned. The smoke discharged from the air outlet pipe 33 carries heat. By arranging the bellows 5 on the outside of the air outlet pipe 33 and the upper end of the air outlet pipe 33 being spiral, the air in the bellows 5 can be heated to increase the air temperature of the air input to the molten iron ladle 9. The ash after the charcoal is burned falls into the waste basin and will not fall into the molten iron ladle 9. If the charcoal in the charcoal basin 42 is insufficient, The charcoal is replenished in time through the discharge pipe 31. When the charcoal is fed from the discharge pipe 31, the baffle 35 rotates downward and opens due to the gravity of the charcoal. After the charcoal falls into the charcoal basin 42 from the discharge pipe 31, it loses the push of gravity, and the baffle 35 rotates upward and merges, sealing the bottom of the discharge pipe 31, which can prevent smoke from leaking from the discharge pipe 31. There is no need to take out the charcoal basin 42 and then replenish charcoal, which can reduce heat loss and improve drying efficiency. According to the measurement of the humidity sensor 6, after the drying is completed, the electric rope winder 7 unwinds, and the movable sleeve 36 slides downward along the outside of the discharge pipe 31. The second sealing cover 37 covers the top of the charcoal basin 42. The movable sleeve 36 seals the connection part between the discharge pipe 31 and the charcoal basin 42, and then the first sealing cover 3 and the drying assembly 4 are driven by the cylinder 2 to rise and remove the molten iron ladle 9. The next molten iron ladle 9 is conveyed to the bottom of the truss 12 by the conveyor belt 1, and the above steps are repeated for drying.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
