[0004] Due to the limitation of the sealing sleeve, the sealing plate on the above-mentioned temperature control channel can only move up and down along the temperature control channel when it is opened, thereby forming a local ventilation hole in the calcining furnace, which will cause temperature difference in the furnace and affect the calcining effect. In addition, the sealing plate needs a large stroke to open, which requires space in the place of use. Therefore, based on the above-mentioned technical problems, they need to be solved.

[0028] Example

[0029] See also Figure 1-4 A calcining device for producing red iron oxide includes a temperature control device, the temperature control device includes a temperature control channel 1 arranged on the calcining device, the temperature control channel 1 is provided with a sealing plate, the sealing plate includes a plurality of sub-plates 2 arranged in sequence, the sub-plates 2 are rotatably connected to the temperature control channel 1 through a pin shaft, the joints between the sub-plates 2 and the joints between the sub-plates 2 and the temperature control channel 1 are provided with sealing gaskets 3, and the sealing plate is connected with an opening and closing component.

[0030] In this embodiment, the temperature control channel 1 matches the inner cavity of the calcining equipment, and the sealing plate is spliced ​​by three sub-plates 2. When the temperature in the calcining equipment is too high, the sub-plate 2 is driven by the opening and closing component to rotate around the pin shaft to open the sealing plate, so that the heat in the calcining equipment is transferred outward through the temperature control channel 1 to avoid the temperature in the calcining equipment from continuing to rise; when the temperature in the calcining equipment is too low, the sub-plate 2 is driven by the opening and closing component to rotate in the opposite direction to close the sealing plate and seal the temperature control channel 1 to avoid the heat in the calcining equipment from being transferred outward, so that the temperature in the calcining equipment gradually rises.

[0031] When the sealing plate is opened, the partition plate 2 is tilted, and vents for heat transfer are formed between the partition plates 2. This arrangement can achieve comprehensive ventilation and cooling inside the calcining equipment, avoiding the formation of temperature differences inside and affecting the calcining effect. In addition, when the partition plate 2 is opened, it rotates around the pin shaft, which greatly reduces the space requirements for the place of use and improves adaptability.

[0032] The opening and closing assembly includes a connecting rod 1 4, a connecting rod 2 5, and a traction rod 6. One end of the connecting rod 1 4 is rotatably connected to the temperature control channel 1 through a rotating shaft 7. The rotating shaft is connected to an opening and closing motor. The other end of the connecting rod 1 4 is rotatably connected to one end of the connecting rod 2 5. The other end of the connecting rod 2 5 is rotatably connected to the traction rod 6. An ear plate is connected to the split plate 2, and the ear plate is rotatably connected to the traction rod 6 through a pin shaft 2 8.

[0033] The opening and closing motor is fixed on the temperature regulating channel 1. When the opening and closing motor is started, the connecting rod 1 4 rotates around the rotating shaft, and drives the traction rod 6 to move through the connecting rod 2 5, so that the dividing plate 2 rotates around the pin shaft 1, and then the sealing plate is opened.

[0034] The opening and closing components can realize synchronous rotation of all the partitions, simplifying the operation and making it easy to control. In addition, when the sealing plate is opened, the partitions 2 are inclined and parallel to each other, and the size of the vents between the partitions 2 can be changed by changing the inclination angle of the partitions 2.

[0035] The cross-sections of the sealing gaskets at the connection between the sub-plates 2 and the sealing gaskets 3 at the connection between the sub-plates 2 and the bottom wall of the temperature regulating channel are both U-shaped with an opening and a transition slope 10 at the opening. The sub-plates 2 are provided with a contraction portion matching the opening of the sealing gasket 3 thereunder.

[0036] Sealing gaskets are provided on the top wall and both side walls of the temperature adjustment channel (the sealing gaskets on the side walls are not shown).

[0037] A contraction portion is provided at the bottom of the partition plate 2, and the sealing gasket 3 on the partition plate 2 below or the bottom wall of the temperature control channel is U-shaped. Since the sealing gasket 3 is elastic, it can provide a certain elastic space when the partition plate is opened and closed, and ensure its close contact under the premise that the partition plate can be opened and closed smoothly; in addition, the sealing gasket 3 is U-shaped and a transition slope is provided at the opening of the U-shape. When the sealing plate is closed, the contraction portion of the partition plate is located in the opening of the sealing gasket, and the partition plate 2 squeezes the sealing gasket 3, so that the sealing gasket 3 at the transition slope position can be in close contact with the side of the contraction portion of the partition plate, thereby ensuring the sealing.

[0038] The temperature regulating channel 1 and the sealing plate are both provided with a heat-insulating layer.

[0039] The provision of the thermal insulation layer can prevent the heat in the calcining equipment from being lost from locations other than the outlet of the temperature regulating channel, thereby achieving accurate temperature control.

[0040] An isolation filter 11 is arranged in the temperature regulating channel 1, and guide slopes 12 and impurity outlets are arranged on the bottom walls of the temperature regulating channel on both sides of the isolation filter, respectively, and a collecting tank 9 is arranged below the impurity outlet.

[0041] In this embodiment, the guiding slope is located on the side of the isolation filter close to the calcining equipment, and the impurity outlet is located on the side of the isolation filter close to the sealing plate.

[0042] The isolation filter can physically isolate the inside of the calcining equipment from the outside world, preventing the flue gas in the calcining equipment from carrying solid impurities to the outside world during the process of opening the sealing plate and ventilation and cooling, and can also prevent external impurities from entering the calcining equipment and having an adverse effect on calcination.

[0043] Solid impurities carried by the flue gas in the calcining equipment are isolated by the isolation filter and then fall down, and then fall back into the calcining equipment through the guide slope, while external impurities are isolated by the isolation filter and then fall into the collection tank.

[0044] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
