Description

Technical Field

[0001] The utility model belongs to the technical field of calcined coke preparation, and particularly relates to a heat energy recovery device for calcined coke preparation. Background Art

[0002] The preparation of calcined coke refers to the process of converting petroleum coke into calcined coke through a high-temperature calcination process. Petroleum coke is a residual by-product in the oil refining process. It is mainly composed of aromatic compounds, has a high fixed carbon content and a low volatile matter. After calcination, the physical and chemical properties of petroleum coke change significantly, and it becomes a material with excellent conductivity and thermal stability. It is widely used in aluminum electrolysis, electrode manufacturing, metallurgy, chemical industry and other fields.

[0003] The existing heat energy recovery device for calcined coke preparation realizes heat energy recovery by passing hot air into the heat energy recovery device, and heats the water circulating in the recovery pipe through heat transfer between the recovery pipe and the hot air, but in actual use, the contact time between the flowing hot air and the recovery pipe is short, so that part of the heat energy leaves the heat energy recovery device without being recovered, resulting in poor heat energy recovery effect and waste of heat energy. Utility Model Content

[0004] In view of this, the utility model aims to provide a heat energy recovery device for calcined coke preparation to address the deficiencies of the prior art. While increasing the contact time between the hot air and the recovery pipe, the hot air can be blocked to a certain extent by the continuous swing of the spoiler while the hot air is blown onto the recovery pipe, thereby further improving the heat recovery effect.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a heat recovery device for calcined coke preparation, including a support frame, a mounting seat is arranged on the lower surface of the support frame, a heat recovery tower is arranged on the upper side of the support frame, an air inlet pipe is arranged at the air inlet opened on the upper surface of the heat recovery tower, an air outlet pipe is arranged at the air outlet opened on the lower surface of the heat recovery tower, a plurality of evenly distributed mounting plates 1 are arranged on the left side of the heat recovery tower, a plurality of evenly distributed mounting plates 2 are arranged on the left side of the heat recovery tower, a recovery pipe is arranged between the heat recovery tower, the mounting plate 1 and the mounting plate 2, four evenly distributed support plates are welded and fixed inside the heat recovery tower, two symmetrically distributed induced draft fans are arranged between the two horizontal support plates, and an auxiliary recovery module for auxiliary heat recovery is also arranged between the heat recovery tower, the mounting plate 1 and the mounting plate 2; a solenoid valve 1 is connected in series inside the air inlet pipe, and a solenoid valve 2 is connected in series inside the air outlet pipe.

[0006] As a further improvement of the utility model, the auxiliary recovery module includes a plurality of evenly distributed rotating shafts rotatably arranged between mounting plate one and mounting plate two, the outer arc surfaces of the rotating shafts are provided with a plurality of vertically evenly distributed spoilers, and the heat recovery tower is also provided with an electronic control unit for driving the rotating shaft to rotate; the electronic control unit includes gears fixedly sleeved on the upper and lower ends of the outer arc surface of the rotating shaft, four evenly distributed guide rails are welded and fixed inside the heat recovery tower, sliding seats are slidably arranged on the outer sides of the guide rails, rack plates are arranged on the side of the sliding seat close to the horizontal center of the heat recovery tower, the gears are respectively meshed and connected with adjacent rack plates, and the heat recovery tower is also provided with a driving assembly for driving the sliding seat to move; the driving assembly includes four adjusting screws evenly rotatably arranged inside the heat recovery tower, the adjusting screws are respectively threadedly connected with adjacent sliding seats, four evenly distributed motors are arranged on the rear side of the heat recovery tower, and the output shafts of the motors are respectively fixed to adjacent adjusting screws by couplings.

[0007] As a further improvement of the utility model, a control panel is arranged on the front side of the support frame, and the induced draft fan, the first solenoid valve, the second solenoid valve and the motor are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, a rubber pad is provided on the lower surface of the mounting seat.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, the operation of the induced draft fan, solenoid valve 1 and solenoid valve 2 is regulated by the control panel, and the evenly arranged mounting plates 1 and 2 inside the heat recovery tower cooperate to increase the travel of the hot air inside the heat recovery tower, thereby increasing the contact time between the hot air and the recovery pipe, heating the water flowing in the recovery pipe, and realizing efficient recovery of heat energy.

[0011] Secondly, the control panel controls the synchronous operation of the four motors, so that the spoiler on the outer arc surface of the shaft continuously swings back and forth. As the hot air flows downward, the continuous swing of the spoiler can block the hot air to a certain extent and blow the hot air to the recovery pipe, thereby further improving the heat recovery effect.

[0012] Thirdly, the coordination of the rack plate and the gear, the adjusting screw and the sliding seat can quickly and stably drive the spoiler to swing back and forth continuously, so that the spoiler can quickly and efficiently assist in the recovery of heat energy.
