Description

Technical Field

[0001] The utility model relates to the technical field of grate cooler air chamber sealing devices, in particular to a rotary kiln grate cooler air chamber sealing device for cement production. Background Art

[0002] Grate cooler is an important main machine in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. At the same time, it provides hot air for rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system. Grate cooler consists of upper shell, lower shell, grate bed, grate bed transmission device, grate bed support device, clinker crusher, leakage zipper machine, automatic lubrication device and cooling air unit.

[0003] For example, the application publication number is "CN109141011A", which is a sealing device for the grate cooler air chamber of a rotary kiln for cement production. By setting a three-way air outlet duct, an air chamber sealing isolation plate and an outer wall of the air chamber, the device completely isolates the two internal air chambers, thereby solving the common problem of poor sealing between air chambers of grate coolers, which disrupts the balance relationship between different wind pressures between adjacent air chambers. No additional sealing device is required during the use of the device. By setting a liquid storage cylinder, a water pump and an atomizing nozzle, the device can remove impurities and dust in the recovered gas by spraying water. By setting an air outlet, the device can recycle the treated hot air and provide it to the rotary kiln for continued use. However, when the sealing device of the grate cooler wind chamber of the rotary kiln for cement production is used, the air is blown from top to bottom. When the air encounters an obstacle below, it will spread, causing the air duct to be disordered and a large amount of dust to be raised. The water sprayed by the atomizing nozzle is not effective in treating the dust. The operator will still inhale most of the dust into the body, which will cause certain harm to the human body. At the same time, the sealing device of the grate cooler wind chamber of the rotary kiln for cement production has no filtering function at the air inlet of the cooling fan, so it is easy to inhale more dust together, causing damage to the cooling fan, thereby reducing the service life of the cooling fan. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the air is blown from top to bottom during use, the air will diffuse when encountering obstacles below, causing the air duct to be turbulent, a large amount of dust to be raised, and the effect of treating the dust with water sprayed by the atomizing nozzle is not good. The operator will still inhale most of the dust into the body, which will cause certain harm to the human body. At the same time, the sealing device of the air chamber of the grate cooler of the rotary kiln for cement production has no filtering function at the air inlet of the cooling fan, so it is easy to inhale more dust together, causing damage to the cooling fan, thereby reducing the service life of the cooling fan.

[0027] Working principle:

[0028] When using the rotary kiln grate cooler air chamber sealing device to cool cement clinker:

[0029] Preparation process:

[0030] First, the operator places the filter 8 on the surface of the two horizontal plates 701, and then manually rotates the two pressure plates 705. The slide grooves processed on the two pressure plates 705 slide along the surface of the rotating plate 704. When the surfaces of the two pressure plates 705 fit the surface of the filter 8, the operator rotates the handle 702 clockwise to drive the rotating plate 704 to rotate 90 degrees. The rotating plate 704 rotates 90 degrees clockwise to prevent the pressure plate from moving, so that the filter 8 can be fixed, and a large amount of dust can be prevented from entering the cooling fan 9, thereby reducing the probability of damage to the cooling fan 9, thereby increasing the service life of the cooling fan 9. At the same time, the two air chambers can be completely separated by the air chamber sealing isolation plate and the sealing gasket, which will not cause the balance relationship between different wind pressures between adjacent air chambers to be disrupted, and the sealing effect is good.

[0031] Cement clinker cooling process:

[0032] Put the cement clinker that needs to be cooled on the surface of the two conveyor belts 3, start the external power supply of the two conveyor belts 3, so that the conveyor belts 3 drive the cement clinker that needs to be cooled to move forward, and the operator turns on the power of the cooling fan 9, and the cooling fan 9 starts to work, and the cold air is transported from the three-way pipe 10 to the two blowing pipes 6 and discharged from the blowing hood 5. When the cement clinker passes under the blowing hood 5, the cold wind blows away the heat in the cement and plastic, so that the cement clinker can be cooled quickly.

[0033] Dust cleaning process:

[0034] The operator starts the power of the vacuum cleaner 4, and the vacuum cleaner 4 starts working. Then the power of the first motor 202 is started. The output shaft of the first motor 202 rotates to drive the first gear 204 to rotate, thereby driving the second gear 205 to rotate. The rotation of the second gear 205 drives the bent plate 206 to slide along the slide groove processed on the fixed plate 203, thereby driving the vertical rod 207 to slide back and forth along the slide groove processed on the first shell 201. The vertical rod 207 moves back and forth, thereby driving the vacuum cleaner 4 to move back and forth, so that the dust can be quickly sucked into the vacuum cleaner 4, and the dust can be cleaned as much as possible, so that the operator inhales less dust and reduces the harm to the operator's body. When there is a lot of dust in the vacuum cleaner 4, the operator opens the box door to clean the dust in the vacuum cleaner 4.

[0035] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
