DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] See also Figures 1 to 17As shown, an energy-saving ladle roaster proposed by the present invention comprises a base 1, a bracket 101 is slidably mounted on the base 1 and a support seat 102 is fixedly mounted on the base 1, a ladle 2 is supported on the support seat 102, wherein a push rod motor 8 is fixedly mounted on the base 1, and the output shaft of the push rod motor 8 is fixedly connected to the bracket 101, and the bracket 101 can be driven to move by the push rod motor 8. A ladle cover 3 is fixedly mounted on the bracket 101, and the ladle cover 3 is driven to move by the bracket 101, so that the ladle cover 3 fits on the ladle 2 to prevent a gap from appearing between the ladle cover 3 and the ladle 2. It also comprises two sets of baking and air return components mounted on the steel ladle cover 3, and the baking and air return components include an injection mechanism rotatably mounted on the ladle cover 3 and an air return mechanism mounted on the injection drive mechanism, the injection mechanism injects flames and drives the drive mechanism and the air return mechanism to rotate in the ladle 2, and the air return mechanism collects the gas in the burning ladle 2 and discharges the collected gas to the outside of the ladle 2 after secondary ignition. The ladle 2 is baked by spraying flame into the ladle 2 through the spray mechanism, and the exhaust gas inside the ladle is continuously transported to the outside of the ladle through the return air mechanism, which can prevent the gas from leaking into the working environment while avoiding excessive pressure inside the ladle 2.

[0020] Further Figure 4 , Figure 5 , Figure 6 In the embodiment, a delivery pipe 301 is rotatably mounted on the ladle cover 3, a connector 302 is fixedly mounted on the delivery pipe 301, and an injection mechanism includes a connection pipe 4 fixedly mounted on the connector 302, an injection pipe 401 is fixedly mounted on the connection pipe 4, a plurality of injection holes 402 are arranged on the injection pipe 401, the connection pipe 4 connects the delivery pipe 301 and the injection pipe 401, and the injection pipe 401 is arranged tangent to the inner wall of the ladle 2. Due to the position relationship of the injection pipe 401, when the flame is injected through the plurality of injection holes 402, the flame can be evenly contacted with the inner wall of the ladle 2, and the delivery pipe 301 can be driven to rotate under the thrust generated when the flame is injected, so that the injection pipe 401 itself rotates, and then the flame can be rotated inside the inner wall of the ladle 2, so that the flame can evenly bake the inside of the ladle 2, thereby accelerating the efficiency of baking the ladle 2.

[0021] Further, Figure 7The air return mechanism includes a collecting box 5 fixedly mounted on the injection pipe 401, and a plurality of one-way valves 501 that enable one-way entry into the collecting box 5 are provided on the collecting box 5, a release pipe 502 and a recovery pipe 503 are fixedly mounted on the collecting box 5, a piston 504 is slidably mounted on the collecting box 5, a first driving wheel 505 is rotatably mounted on the piston 504, a connecting block 506 is fixedly mounted on the collecting box 5, a sliding rod 512 is slidably mounted on the connecting block 506, and a second driving wheel 507 is rotatably mounted on the sliding rod 512, a driving component that drives the sliding rod 512 and the piston 504 to move is installed on the ladle cover 3, a releasing component that controls the unblocking state of the releasing pipe 502 is installed in the releasing pipe 502, a recovering component that controls the unblocking state of the recovering pipe 503 is installed in the recovering pipe 503, and the driving component controls the movement state of the releasing component and the recovering component. The gas after combustion inside the ladle 2 will increase the pressure inside the ladle 2 and enable the gas to enter the collecting box 5 through the one-way valve 501, at which time oxygen is transported to the collecting box 5. At this time, if the gas inside the collecting box 5 is not completely burned, it can be re-burned inside the collecting box 5 and released again to the ladle 2 through the release pipe 502, ensuring that the fuel can be completely burned, improving energy utilization, and preventing incomplete combustion from generating harmful substances. If the gas inside the collecting box 5 cannot be re-burned, it will be discharged to the outside of the ladle 2 through the recovery pipe 503, thereby preventing the gas pressure inside the ladle 2 from being too high and ensuring that all discharged gases are re-burned.

[0022] The driving assembly includes a first protrusion 508 and a second protrusion 509 fixedly mounted on the ladle cover 3, a first connecting groove 510 is provided on the first protrusion 508 and the ladle cover 3, the first driving wheel 505 is slidably connected to the first connecting groove 510, a second connecting groove 511 is provided on the second protrusion 509 and the ladle cover 3, and the second driving wheel 507 is slidably connected to the second connecting groove 511. When the first driving wheel 505 moves to the first protrusion 508, the piston 504 will be driven to move, and when the second driving wheel 507 moves to the second protrusion 509, the sliding rod 512 will be driven to move.

[0023] It is worth noting that Fig.14 , Fig.15 In the embodiment, the first protrusion 508 is provided with a first rising portion 5081 and a first descending portion 5082 and a first flat portion 5083 located between the first rising portion 5081 and the first descending portion 5082, and the second protrusion 509 is provided with a second rising portion 5091 and a second descending portion 5092 and a second flat portion 5093 located between the second rising portion 5091 and the second descending portion 5092. Fig.14In the position relationship diagram of the first protrusion 508 and the second protrusion 509, when the second driving wheel 507 moves to the second rising portion 5091, the first driving wheel 505 does not contact the first rising portion 5081, when the second driving wheel 507 moves to the second gentle portion 5093, the first driving wheel 505 moves to the first rising portion 5081, when the second driving wheel 507 moves to the second descending portion 5092, the first driving wheel 505 moves to the first gentle portion 5083, and when the second driving wheel 507 moves to the ladle cover 3, the first driving wheel 505 moves to the second descending portion 5092.

[0024] Among them, the recovery component includes a connecting plate 513 fixedly installed on the sliding rod 512, a push rod 514 fixedly installed on the connecting plate 513, a first driving plate 515 slidably installed on the push rod 514, a connecting shaft 516 fixedly installed on the first driving plate 515, a primary recovery hole 5031 and a secondary recovery hole 5032 with a larger aperture than the primary recovery hole 5031 are installed in the recovery tube 503, a recovery slide rod 517 is fixedly installed in the recovery tube 503, a recovery plug 518 is slidably installed on the recovery slide rod 517, the recovery plug 518 is fixedly connected to the connecting shaft 516, the recovery tube 503 is connected to the collecting box 5, the primary recovery hole 5031 and the secondary recovery hole 5032 pass through the recovery tube 503, and a connecting tube 519 is fixedly installed on the recovery tube 503. When the second driving wheel 507 drives the sliding rod 512 to move to the right (when the second driving wheel 507 moves to the second rising portion 5091), it will drive the push rod 514 to squeeze the first driving plate 515, thereby driving the connecting shaft 516 to descend, thereby driving the recovery plug 518 to descend, and then the recovery plug 518 located in the primary recovery hole 5031 moves to the inside of the secondary recovery hole 5032, so that the recovery pipe 503 is connected, and then the piston 504 presses the gas inside the collection box 5 into the inside of the connecting pipe 519 through the recovery pipe 503, as shown in FIG. Fig.11 , 12 shown.

[0025] Further in Figures 8 to 10In the figure, the release assembly includes a horizontal plate 520 fixedly mounted on the slide rod 512, a vertical rod 521 fixedly mounted on the horizontal plate 520, a push block 522 fixedly mounted on the vertical rod 521, a second driving plate 523 slidably mounted on the push block 522, a push column 524 fixedly mounted on the second driving plate 523, a first-level release hole 5021 and a second-level release hole 5022 with a larger aperture than the first-level release hole 5021 are provided in the release tube 502, a release slide rod 530 is fixedly mounted in the release tube 502, a release plug 525 is slidably mounted on the release slide rod 530, a reset rod 526 is fixedly mounted on the release plug 525, and a socket 527 coaxial with the reset rod 526 is provided on the piston 504. When the second driving wheel 507 is located on the ladle cover 3, the push column 524 will be located outside the secondary release hole 5022. If the gas inside the collecting box 5 undergoes secondary combustion at this time, the other pressures in the collecting box 5 will increase instantly, making the air pressure inside the collecting box 5 greater than the air pressure inside the ladle 2, thereby pushing the release plug 525 to move to the inside of the secondary release hole 5022. At this time, the flame can be sprayed into the ladle 2 through the release pipe 502, so that the heat generated by the secondary combustion can be sprayed into the ladle 2. At this time, the release plug 525 will move to the right side of the push column 524, and then the second driving wheel 507 moves to the second rising portion 5091, and then the first driving wheel 505 moves to the first rising portion 5081. At this time, the piston 504 can be driven to compress the gas inside the collecting box 5, so that the gas flows out through the recovery pipe 503, and because the release pipe 502 is not blocked at this time, a part of the gas and heat will be discharged into the ladle through the release pipe 502.

[0026] Furthermore, if the gas inside the collecting box 5 cannot be ignited for the second time, when the first driving wheel 505 subsequently moves to the first rising portion 5081 (that is, when the piston 504 compresses the gas inside the collecting box 5), the push column 524 will have passed through the second rising portion 5091, and the sliding rod 512 at this time will squeeze the second driving plate 523 through the pushing block 522, thereby pushing the push column 524 to move to the inside of the secondary release hole 5022, preventing the release plug 525 from moving to the inside of the secondary release hole 5022, so that the release pipe 502 cannot be in a connected state when the gas inside the collecting box 5 is compressed and the air pressure increases. At this time, the gas inside the collecting box 5 will be completely pressed into the inside of the connecting pipe 519 through the recovery pipe 503.

[0027] Subsequently, when the second driving wheel 507 passes through the second descending portion 5092, the push column 524 and the recovery plug 518 will be reset, and then the first driving wheel 505 passes through the second descending portion 5092, driving the piston 504 to move to the outside of the collecting box 5, so that the collecting box 5 absorbs the gas inside the ladle 2.

[0028] It should be noted that Fig.17 In the collecting box 5, an oxygen supply hole 528 is provided in the collecting box 5, an oxygen supply connecting pipe 529 is fixedly installed on the oxygen supply hole 528, and a pipeline system for conveying oxygen and fuel gas and exhaust gas through the recovery pipe 503 is installed in the delivery pipe 301. The piping system includes a fuel supply pipe 6 fixedly mounted on the bracket 101, the fuel supply pipe is connected to the delivery pipe 301 and is rotatably connected, an oxygen supply valve 601 and a fuel valve 602 are provided on the fuel supply pipe 6, an exhaust pipe 603 is fixedly mounted in the delivery pipe 301, a diverter head 604 is fixedly mounted on the exhaust pipe 603, a connecting pipe 519 is connected to the diverter head 604, an oxygen supply pipe 605 is fixedly mounted in the exhaust pipe 603, an oxygen supply connecting pipe 529 is connected to the oxygen supply pipe 605, a waste discharge box 606 connected to the exhaust pipe 603 is fixedly mounted on the bracket 101, a waste discharge joint 607 is fixedly mounted on the waste discharge box 606, and an oxygen supply joint 608 connected to the oxygen supply pipe 605 is fixedly mounted on the bracket 101. Oxygen and fuel gas are respectively input into the delivery pipe 301 through the oxygen supply valve 601 and the fuel valve 602, so that the oxygen and fuel gas enter the injection pipe 401, are ignited and then injected into the ladle 2, and oxygen is input into the oxygen supply pipe 605 through the oxygen supply joint 608, so that oxygen can enter the collecting box 5 through the oxygen supply connecting pipe 529 and the oxygen supply hole 528, so that the gas in the collecting box 5 has the conditions for secondary ignition, and the exhaust gas entering the connecting pipe 519 through the recovery pipe 503 will enter the exhaust joint 607 through the exhaust pipe 603, and the exhaust gas will be discharged in the same way through the exhaust joint 607.

[0029] like Fig.16 As shown, the ladle roaster of this embodiment also includes a pressure relief mechanism installed on the ladle cover 3, the pressure relief mechanism includes a through hole 7 provided on the ladle cover 3, a pressure relief pipe 701 connected to the through hole 7 is fixedly installed on the ladle cover 3, a first-level pressure relief hole 7011 and a second-level pressure relief hole 7012 with a larger aperture than the first-level pressure relief hole 7011 are provided in the pressure relief pipe 701, a pressure relief slide bar 702 is slidably installed on the pressure relief pipe 701, a pressure relief plug 703 is fixedly installed on the pressure relief slide bar 702, a threaded seat 704 is fixedly installed on the ladle cover 3, a screw rod 705 is threadedly connected to the threaded seat 704, a pressure head 706 is fixedly installed on the screw rod 705, a spring 707 is fixedly installed on the pressure head 706, and the other end of the spring 707 is fixedly connected to the pressure relief slide bar 702. When the efficiency of the collection box 5 in discharging waste gas is insufficient, the air pressure inside the ladle 2 will continue to rise. At this time, the air pressure inside the ladle 2 will gradually overcome the elastic force of the spring 707 to move the pressure relief plug 703 to the secondary pressure relief hole 7012, so that the pressure relief pipe 701 is connected, thereby discharging the waste gas inside the ladle 2 to prevent the air pressure inside the ladle 2 from being too high and causing damage to the ladle 2. A pipeline can be connected to the pressure relief pipe 701 to allow the waste gas passing through the pressure relief pipe 701 to enter the waste discharge joint 607.

[0030] Working principle: Due to the positional relationship of the injection pipe 401, when the flame is sprayed through multiple nozzles 402, the flame can evenly contact the inner wall of the ladle 2, and can drive the conveying pipe 301 to rotate under the thrust generated when the flame is sprayed, so that the injection pipe 401 itself rotates, and then the flame can rotate inside the inner wall of the ladle 2, so that the flame can evenly bake the inside of the ladle 2, thereby speeding up the baking efficiency of the ladle 2.

[0031] The gas after combustion inside the ladle 2 will increase the pressure inside the ladle 2 and enable the gas to enter the collecting box 5 through the one-way valve 501, at which time oxygen is transported to the collecting box 5. At this time, if the gas inside the collecting box 5 is not completely burned, it can be re-burned inside the collecting box 5 and released again to the ladle 2 through the release pipe 502, ensuring that the fuel can be completely burned, improving energy utilization, and preventing incomplete combustion from generating harmful substances. If the gas inside the collecting box 5 cannot be re-burned, it will be discharged to the outside of the ladle 2 through the recovery pipe 503, thereby preventing the gas pressure inside the ladle 2 from being too high and ensuring that all discharged gases are re-burned.

[0032] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
