Therefore, the inclined rail and the feeding trolley cannot directly convey the high-temperature pellet material. A chain plate machine needs to be added to transfer the high-temperature pellet material outside the main plant house, and then the inclined rail and the feeding trolley convey the high-temperature pellet material. Through multiple transfers, not only the waste heat resource is greatly lost, but also the equipment investment cost is increased, and the economic efficiency of waste heat recovery is greatly reduced.

[0028] The system further includes a horizontal guide rail 70 and a driving assembly 80.

[0029] The horizontal guide rail 70 is arranged in the main factory building 10 and fixedly connected with the bottom of the main factory building 10. The first end of the horizontal guide rail 70 is located directly below the discharge port of the shaft furnace 11, and the second end of the horizontal guide rail 70 is connected with the bottom of the inclined rail 30.

[0030] The driving assembly 80 is used to control the movement of the loading trolley 40 on the horizontal guide rail 70.

[0031] In the initial state, the loading trolley 40 is located at the first end of the horizontal guide rail 70.

[0032] The specific working process of the system is as follows:

[0033] Firstly, the worker controls the discharge port of the shaft furnace 11 to open, and the high-temperature pellet material discharged from the shaft furnace 11 will directly fall into the loading trolley 40.

[0034] Then, the worker controls the winch 50 to start, and the winch 50 winds the traction rope 31. After the traction rope 31 passes the roller 32, the traction rope 31 pulls the loading trolley 40 to move upwards on the inclined rail 30. When the loading trolley 40 moves to the top of the inclined rail 30, the loading trolley 40 will overturn under the action of the material pouring assembly 60. The high-temperature pellet material loaded in the loading trolley 40 will be poured out through the discharge port of the loading trolley 40, and the high-temperature pellet material will fall into the pellet waste heat recovery device 20 for waste heat recovery.

[0035] Finally, the worker controls the winch 50 to release the traction rope 31. Under the action of gravity, the loading trolley 40 will move downwards on the inclined rail 30. When the loading trolley 40 moves to the bottom of the inclined rail 30, the driving assembly 80 starts to control the loading trolley 40 to move to the first end of the horizontal guide rail 70. The system returns to the initial state and is ready for the next work.

[0036] In one embodiment, the driving assembly 80 comprises a transmission sprocket 81, a driving sprocket 82, an endless chain 83 and a motor.

[0037] The transmission sprocket 81 is fixedly installed on the feeding trolley 40. The driving sprocket 82 is two in number, and is arranged on the two sides of the horizontal guide rail 70 and is rotatably connected with the main factory building 10. The two ends of the endless chain 83 are engaged with the two driving sprockets 82 respectively, and the endless chain 83 is also engaged with the transmission sprocket 81. The motor is fixedly installed on the main factory building 10 and is used to control the rotation of one of the driving sprockets 82.

[0038] When the driving assembly 80 is started, the motor drives one of the driving sprockets 82 to rotate, and in turn drives the endless chain 83 to start rotating. When the feeding trolley 40 moves to the bottom of the inclined guide rail 30, the transmission sprocket 81 will automatically engage with the endless chain 83, so that the endless chain 83 drives the feeding trolley 40 to move to the first end of the horizontal guide rail 70, so that the system returns to the initial state and prepares for the next work.

[0039] In one embodiment, an arc-shaped guide rail 90 is arranged between the inclined guide rail 30 and the horizontal guide rail 70, and the two ends of the arc-shaped guide rail 90 are fixedly connected with the inclined guide rail 30 and the horizontal guide rail 70 respectively, and the two ends of the arc-shaped guide rail 90 are tangent to the inclined guide rail 30 and the horizontal guide rail 70 respectively.

[0040] The design of the arc-shaped guide rail 90 makes the connection between the horizontal guide rail 70 and the inclined guide rail 30 more smooth, ensuring that the feeding trolley 40 can pass smoothly.

[0041] In one embodiment, a guide wheel 91 is arranged above the arc-shaped guide rail 90, and the guide wheel 91 is rotatably connected with the main factory building 10 and is in contact with the traction rope 31.

[0042] The design of the guide wheel 91 can change the traction direction of the traction rope 31, so as to better pull the feeding trolley 40 located on the horizontal guide rail 70.

[0043] In one embodiment, the transmission sprocket 81 is fixedly installed on the axle of the caster 46 of the feeding trolley 40, which further facilitates the installation of the transmission sprocket 81 by the staff.

[0044] In one embodiment, a cover plate 41 is arranged at the feeding inlet of the feeding trolley 40, the first end of the cover plate 41 is rotatably connected with the feeding trolley 40, and the second end of the cover plate 41 is detachably connected with the feeding trolley 40.

[0045] When the charging trolley 40 is charging at the directly below of the discharge port of the shaft furnace 11, the cover plate 41 is in the open state, facilitating receiving the high-temperature pellet material discharged by the shaft furnace 11. When the charging is completed, the second end of the cover plate 41 is connected with the charging trolley 40, which aims to prevent the high-temperature pellet material in the charging trolley 40 from spilling over when the charging trolley 40 is running from the horizontal guide rail 70 to the inclined guide rail 30.

[0046] In one embodiment, the bottom of the second end of the cover plate 41 is provided with a first clamping hook 42, and the inner wall of the charging trolley 40 is provided with a second clamping hook 43 which is clamped with the first clamping hook 42.

[0048] When the second end of the cover plate 41 moves downward, the first inclined surface 44 will contact the second inclined surface 45, thereby pushing the second clamping hook 43 to swing outward. When the first inclined surface 44 is disengaged from the second inclined surface 45, the first clamping hook 42 will be clamped with the second clamping hook 43 under the action of the torsional spring, thereby connecting the second end of the cover plate 41 with the charging trolley 40.

[0049] When the cover plate 41 needs to be opened, the staff moves the second clamping hook 43 outward, and then opens the second end of the cover plate 41, at this time the feeding port of the charging trolley 40 is open, facilitating receiving the high-temperature pellet material discharged by the shaft furnace 11.
