Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6In this embodiment, a sleeve kiln ash discharge structure includes...

[0035] Ash discharge structure 1 includes an ash hopper 11 and an annular cover 13 disposed at the bottom of the ash hopper 11. A scraper 14 is connected to one side of the opening of the annular cover 13, and a guide plate 15 is connected to the opening of the annular cover 13.

[0036] Rotating structure 2 includes a turntable 21 disposed at the bottom of annular cover 13, a connecting cylinder 22 connected to the top of turntable 21, and a screw cone 23 connected to the top of connecting cylinder 22. An exhaust port is provided between the conical covers of the screw cone 23, and an air outlet 25 corresponding to the exhaust port is installed inside the screw cone 23.

[0037] Drive structure 3 for driving the turntable 21 to rotate; and

[0038] The sealing structure 5 for blocking the exhaust port includes a rotating cylinder 51 slidably disposed in the screw cone 23 and a movable ring 54 connected to the top of the rotating cylinder 51. The top of the movable ring 54 is connected to an arc-shaped sealing strip 55 for blocking the exhaust port. The arc-shaped sealing strip 55 is provided with a ventilation opening 56 corresponding to the exhaust port. The turntable 21 is equipped with an adjusting component for adjusting the position of the rotating cylinder 51.

[0039] Using the above scheme, the calcined lime falls into the ash hopper 11 and is guided to the surface of the turntable 21 by the outer wall of the screw cone 23. As the turntable 21 rotates, it scrapes the lime accumulated in the annular cover 13 toward the ash outlet. The scraper 14 and the guide plate 15 work together to move the material out. During the discharge, the air outlet 25 sprays air to help disperse the material. The closed structure 5 adjusts the air volume according to the material quantity or blocks the air outlet 25 to avoid blockage.

[0040] By driving the structure 3 to rotate, the connecting cylinder 22 and the screw cone 23 rotate synchronously. By spraying air through the air outlet 25, small-diameter materials can be discharged.

[0041] Please see Figure 4 The adjusting component includes an electric telescopic rod 53 installed at the bottom of the turntable 21. The outer wall of the rotating cylinder 51 is slidably engaged with the inner wall of the connecting cylinder 22. The bottom end of the rotating cylinder 51 extends to the bottom of the turntable 21 and is rotatably connected to the rotating ring 52. The bottom telescopic end of the electric telescopic rod 53 is connected to the rotating ring 52.

[0042] The electric telescopic rod 53 pushes the rotating ring 52 to control the rotating cylinder 51 to slide up and down in the connecting cylinder 22. When the arc-shaped seal 55 moves, the alignment of the vent 56 with the exhaust port adjusts the actual air volume, avoiding ineffective blowing and dust blockage.

[0043] Furthermore, the screw taper 23 is provided with a vertical groove for the arc-shaped seal 55 to slide, so that the arc-shaped seal 55 can slide up and down stably.

[0044] Please see Figure 4 and Figure 5 An air inlet pipe 24 is inserted inside the rotating cylinder 51, and the air inlet of the air outlet 25 is connected to the air outlet at the top of the air inlet pipe 24. The moving ring 54 is provided with a through hole for the air inlet pipe 24 to pass through.

[0045] Specifically, the air inlet pipe 24 can be connected to an external air supply device via a rotary joint.

[0046] Please see Figure 1 and Figure 3 It also includes a mounting plate 4, the top of which is connected to a support ring 34 for supporting the stable rotation of the turntable 21; thus enabling the turntable 21 to rotate stably.

[0047] Please see Figure 3 The drive structure 3 includes a gear ring 31 connected to the bottom of the turntable 21, a drive motor 33 is mounted on the top of the mounting plate 4, and a drive gear 32 that meshes with the gear ring 31 is mounted on the output shaft of the power output end of the drive motor 33.

[0048] Specifically, the operation of the drive motor 33 can drive the drive gear 32 to rotate, and under the transmission of the drive gear 32, the drive gear ring 31 rotates, so that the turntable 21 rotates stably on the top of the support ring 34.

[0049] Please see Figure 1 and Figure 2 The top of the mounting plate 4 is connected to a support frame 12 for supporting the rotation of the ash hopper 11, and the annular cover 13 is fixed on the support frame 12.

[0050] Specifically, the turntable 21 rotates while the annular cover 13 does not rotate. The material moves on the turntable 21 and is then output from the guide plate 15 under the scraping action of the scraper 14.

[0051] The working principle of this utility model is as follows: After calcination, the lime falls into the ash hopper 11 and is guided to the surface of the turntable 21 by the outer wall of the screw cone 23. While the turntable 21 is rotating, the annular cover 13 does not rotate. The lime accumulated in the annular cover 13 is scraped towards the ash outlet. The scraper 14 and the guide plate 15 work together to move the material out. During the discharge, the air outlet 25 sprays air to help disperse the material. The electric telescopic rod 53 pushes the rotating ring 52 to control the rotating cylinder 51 to slide up and down in the connecting cylinder 22. When the arc-shaped seal 55 moves, the alignment of the ventilation port 56 with the exhaust port adjusts the actual air volume to avoid ineffective blowing and dust blockage.

[0052] By driving the structure 3 to rotate, the connecting cylinder 22 and the screw cone 23 rotate synchronously. By spraying air through the air outlet 25, small-diameter materials can be discharged.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
