Description

Technical Field

[0001] The utility model relates to the technical field of kiln furnace processing, and particularly relates to a preheating device for a kiln furnace heating furnace body. Background Art

[0002] As an important industrial equipment, kiln furnaces are widely used in various industrial fields such as ceramics, metallurgy, glass, etc. During the working process of the kiln furnace, furnace body preheating is a crucial link, which is directly related to the heating efficiency of the kiln furnace, energy consumption, and product quality. Traditional kiln furnace preheating methods often adopt direct heating, which is not only inefficient but also consumes a large amount of energy, not meeting the current development requirements of energy conservation and environmental protection.

[0003] To solve this problem, the air heating method is increasingly used in modern industry to preheat the kiln furnace. This method heats the air and then introduces the high-temperature air into the kiln furnace to achieve rapid heating of the kiln furnace. This method not only significantly improves the preheating efficiency but also helps to reduce energy consumption, meeting the green and low-carbon requirements of current industrial development. However, this preheating method also faces certain challenges. Among them, the most prominent problem is how to deal with the waste gas generated during the heating of the kiln furnace. During the preheating process, a large amount of waste gas is generated inside the kiln furnace. These waste gases not only carry rich heat but also may contain harmful soot and gases. If these waste gases are directly discharged into the atmosphere without treatment, it will not only cause serious energy waste but also may pollute the ecological environment. Therefore, it is particularly important to effectively treat the waste gas generated by heating the kiln furnace.

[0040] As Figure 5 、 Figure 6As shown in the figure, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, the cooling structure 5 includes a water tank 51. The lower end of the water tank 51 is fixedly connected to the upper end of the support frame 8. A filter box 52 is slidably connected to the middle of the water tank 51.

[0042] In this embodiment, then the air filtered by the filter mesh plate 44 will flow into the inner cavity of the second purification chamber 54. Then, by running the water pump 531, the water resources in the inner cavity of the water tank 51 are extracted by the water pump 531. Then, the water extracted by the water pump 531 is conveyed to the inner cavity of the first spray pipe 533 through the first water pipe 532. Through the cooperation of the first spray pipe 533, the connecting pipe 534 and the second spray pipe 535, the water in the inner cavity of the first spray pipe 533 can be conveyed to the inner cavity of the second spray pipe 535 by the connecting pipe 534. Then, by the cooperation of the second spray pipe 535 and the first spray pipe 533, the water can be sprayed into the inner cavity of the second purification chamber 54, so as to complete the cooling of the waste gas flowing into the inner cavity of the second purification chamber 54. Then, the water after cooling the waste gas will be collected in the inner cavity of the filter box 52, and then the filter box 52 is used to filter it. Thus, the filtered water will flow back into the inner cavity of the water tank 51 again and wait to be used again.

[0043] Such as Figure 7 、 Figure 8As shown, on the basis of Embodiment 3, the present utility model provides a technical solution: Preferably, the degassing structure 6 includes a third purification chamber 61. The lower end of the third purification chamber 61 is fixedly connected to the upper end of the support frame 8. One side of the third purification chamber 61 close to the second purification chamber 54 is fixedly connected to the second purification chamber 54, and the inner cavity of the third purification chamber 61 is communicated with the inner cavity of the second purification chamber 54. An upper portion of the inner cavity of the third purification chamber 61 is fixedly connected with a stopper 62.

The upper end of the carbon placement box 631 is symmetrically and fixedly connected with sliding blocks 633. The sliding blocks 633 are slidably connected to the lower portion of the stopper 62.

[0044] In this embodiment, then the exhausted gas after temperature reduction will flow into the inner cavity of the third purification chamber 61, and then be blocked by the stopper 62. Thus, the exhausted gas will flow into the inner cavity of the carbon placement box 631 through a plurality of air inlet holes 632, and then be filtered by the activated carbon placed in the inner cavity of the carbon placement box 631, so that the harmful gases in the exhausted gas can be intercepted. Then the exhausted gas after filtration will flow out from the inner cavity of the carbon placement box 631, and then these exhausted gases will enter the inner cavity of the air box 71 through the inner cavity of the intake pipe 75, so that they can be discharged from the device through the exhaust pipe 74.

[0045] Next, the working principle of the kiln heating furnace body preheating device will be specifically described.

[0046] As Figures 1-9 shown, when it is necessary to treat the exhausted gas after the kiln is heated, first, the air heater 1 can extract the air around the device, then heat the extracted air, and then convey the heated air into the inner cavity of the kiln body 2, so that the kiln body 2 can be heated up. Then, by running the motor 73, the motor 73 drives the stirring fan 72 to rotate in the inner cavity of the air box 71, so that the air in the inner cavity of the third purification chamber 61 can be evacuated through the intake pipe 75. By evacuating the air in the inner cavity of the third purification chamber 61, the gas in the device can be driven to circulate, so that the heated exhausted gas in the inner cavity of the kiln body 2 can be conveyed into the inner cavity of the dust filtering structure 4 through the outlet pipe 3, and then the exhausted gas conveyed into the inner cavity of the first connecting block 41 is filtered by the filter mesh plate 44, so that the particles and other impurities in the exhausted gas can be intercepted in the inner cavity of the particle box 42;

[0047] Then the air filtered by the filter screen plate 44 will flow into the inner cavity of the second purification chamber 54. Then, by operating the water pump 531, the water resource in the inner cavity of the water tank 51 is extracted by the water pump 531. Next, the water extracted by the water pump 531 is conveyed through the first water pipe 532 into the inner cavity of the first spray pipe 533. Through the cooperation of the first spray pipe 533, the connecting pipe 534, and the second spray pipe 535, the water in the inner cavity of the first spray pipe 533 can be conveyed into the inner cavity of the second spray pipe 535 through the connecting pipe 534. Then, by the cooperation of the second spray pipe 535 and the first spray pipe 533, the water can be sprayed into the inner cavity of the second purification chamber 54, so as to complete the cooling of the waste gas flowing into the inner cavity of the second purification chamber 54. Then, the water after cooling the waste gas will gather in the inner cavity of the filter box 52, and then the filter box 52 is used to filter it. Thus, the filtered water will flow back into the inner cavity of the water tank 51 again and wait to be reused;

[0048] Next, the waste gas after cooling will flow into the inner cavity of the third purification chamber 61, and then it is blocked by the baffle 62. Thus, the waste gas will flow into the inner cavity of the carbon placement box 631 through a number of air inlet holes 632, and then it is filtered by the activated carbon placed in the inner cavity of the carbon placement box 631, so that the harmful gases in the waste gas can be intercepted. Then, the waste gas after filtration will flow out of the inner cavity of the carbon placement box 631. Next, these waste gases will enter the inner cavity of the air box 71 through the inner cavity of the air inlet pipe 75, and thus can be discharged from the device through the exhaust pipe 74.

[0049] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
