[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0021] A dust collection device for the feeding port of a calcium aluminate rotary kiln, comprising a kiln body 1. Support legs 2 are fixedly installed at the four corners of the lower end face of the kiln body 1. A feeding plate 3 is communicated and arranged on the left end face of the kiln body 1. An outer shell 4 is arranged outside the feeding plate 3, and the outer shell 4 is fixedly connected with the kiln body 1. A dust collector 5 is fixedly installed on the upper end face of the outer shell 4, and the dust collector 5 is communicated with the outer shell 4. A discharge port 6 is communicated and arranged on the upper end face of the dust collector 5. A motor 7 is fixedly installed on the front end face of the outer shell 4. Support members 9 are fixedly installed on both sides of the left end face of the kiln body 1. A rotating shaft 8 is rotatably connected between the two groups of support members 9. The output shaft of the motor 7 is fixedly connected with the rotating shaft 8. A cleaning wheel one 10 is fixedly installed on the outer surface of the rotating shaft 8, and the cleaning wheel one 10 is arranged directly above the feeding plate 3.

[0022] After the production of the calcium aluminate rotary kiln is completed, when feeding from the feeding port, it is inevitable that a lot of dust will be generated. At this time, by starting the motor 7 and the dust collector 5, the motor 7 will drive the rotating shaft 8 to rotate. The cleaning wheel one 10 on the rotating shaft 8 will first contact the finished product, strike and clean the dust on its outer surface, and disperse it into the air.

[0023] A worm 11 is arranged above the rotating shaft 8, and the worm 11 is rotatably connected between the two groups of support members 9.

[0024] A gear two 13 is fixedly installed at the rear end of the worm 11, and a gear one 12 is fixedly installed at the rear end of the rotating shaft 8. The gear one 12 is meshed with the gear two 13.

[0025] A worm gear 14 is meshed with one side of the worm 11, and a cleaning wheel two 15 is fixedly installed on the lower end face of the worm gear 14.

[0026] The cleaning wheel two 15 is embedded and connected to the inner wall of the feeding port, and cleaning brushes are arranged on the outer surfaces of both the cleaning wheel one 10 and the cleaning wheel two 15.

[0027] Secondly, the rotating shaft 8 will drive the gear one 12 to rotate. The gear two 13 on the worm 11 is meshed with the gear one 12, so the worm 11 will be driven to rotate synchronously. The worm gear 14 on the cleaning wheel two 15 is meshed with the worm 11, so the two groups of cleaning wheels two 15 rotate synchronously. Similarly, the dust on their outer surfaces is struck and cleaned and dispersed into the air. At this time, the dust collector 5 inhales the dust inside the outer shell 4 and discharges it through the discharge port 6, thus avoiding the powder from flowing in the air and polluting the nearby environment.

[0028] Two groups of worm gears 14 and cleaning wheels two 15 are correspondingly arranged and symmetrically arranged on both sides inside the feeding plate 3.

[0029] With the present utility model, by providing the first cleaning wheel 10 and the second cleaning wheel 15, the dust on the outer surface of the product is struck and cleaned, and dispersed in the air. The dust collector 5 sucks the dust inside the housing 4 into it and discharges it through the discharge port 6, thereby preventing the powder from circulating in the air and polluting the nearby environment.

[0030] Working principle: When the calcium aluminate rotary kiln finishes production and discharges materials from the feeding port, a lot of dust will inevitably be generated. At this time, by starting the motor 7 and the dust collector 5, the motor 7 will drive the rotating shaft 8 to rotate. The first cleaning wheel 10 on the rotating shaft 8 will first come into contact with the finished product, strike and clean the dust on its outer surface, and disperse it in the air. Secondly, the rotating shaft 8 will drive the first gear 12 to rotate. The second gear 13 on the worm 11 meshes with the first gear 12, so the worm 11 will be driven to rotate synchronously. The worm gear 14 on the second cleaning wheel 15 meshes with the worm 11, so the two second cleaning wheels 15 rotate synchronously. Similarly, the dust on their outer surfaces is struck and cleaned, and dispersed in the air. At this time, the dust collector 5 sucks the dust inside the housing 4 into it and discharges it through the discharge port 6, thereby preventing the powder from circulating in the air and polluting the nearby environment.

[0031] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
