[0002] Lime kiln is a kiln used to calcine limestone. Its main purpose is to convert limestone (mainly calcium carbonate) into quicklime (mainly calcium oxide) after high-temperature calcination. Lime kiln is widely used in construction, metallurgy, chemical industry and other industries, and is an important equipment for producing lime.

[0003] A lime discharger needs to be installed at the discharge port of the lime kiln, and the lime on the ash tray is scraped off by a scraper provided on the lime discharger;

[0004] The scraper of the ash discharger in the prior art usually does not have the effect of angle adjustment, which means that it can only adapt to one type of lower hopper during use, and its flexibility of use is poor; the existing ash discharger scraper usually needs to keep in contact with the lower hopper during use, which is easy to cause the scraper to wear after long-term use, shortening its service life; therefore, a double-scraper rotary ash discharger with kiln bottom for lime production is proposed to solve the above problems.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-4 In this embodiment, a double-scraper rotary ash discharger for lime production at the bottom of a kiln comprises a support frame 1 and a kiln body 11. A conical hopper 12 is arranged at the bottom of the support frame 1, a drop pipe 13 is arranged at the bottom of the conical hopper 12, a support rod 14 is arranged in the drop pipe 13, a mounting seat 15 is arranged in the middle of the support rod 14; a transmission motor 16 is arranged in the mounting seat 15, an output shaft of the transmission motor 16 passes through the mounting seat 15 and is fixedly connected with a tool holder assembly 2; a connecting platform 21 is arranged on the tool holder assembly 2, two first scrapers 22 are fixedly connected to the outer periphery of the connecting platform 21, both ends of the two first scrapers 22 are rotatably connected with the scraper assembly 3, a slide groove 23 is opened on the two first scrapers 22, a slider 24 is slidably connected in the slide groove 23, a limit member 25 is arranged on the top of the slider 24, the limit member 25 is rotatably connected with a connecting rod 27, and the other end of the connecting rod 27 is rotatably connected with the scraper assembly 3. A connecting seat 26 is provided on the slider 24 , and the connecting seat 26 is used to limit the slider 24 .

[0025] This connection method enables the scraper assembly 3 to be effectively adjusted in angle during use, thereby effectively increasing its adaptability during use.

[0026] Furthermore, the staff can configure the first scraper 22 as a telescopic rod, thereby ensuring that it can have a better adjustment effect during use.

[0027] As a preferred technical solution in this embodiment: during actual use, the staff can control the connecting seat 26 to cancel the limiting effect on the slider 24, and then the staff can control the slider 24 to produce a sliding effect in the slide groove 23. During the displacement of the slider 24, the connecting rod 27 can be driven to produce a displacement effect. During the displacement of the connecting rod 27, the scraper assembly 3 can be effectively driven to produce a rotation effect around the end of the first scraper 22. During the rotation of the scraper assembly 3, the angle between it and the first scraper 22 can be changed, so that it can adapt to conical hoppers 12 with different inclinations, effectively increasing its adaptability during use and ensuring its use effect.

[0028] Embodiment 2:

[0029] See also Figure 5 In order to reduce the friction between the scraper assembly 3 and the hopper, the scraper assembly 3 in this embodiment includes a second scraper 31, and a connecting block 32 is provided on one side of the second scraper 31, and the connecting block 32 is rotatably connected to the connecting rod 27. The second scraper 31 is provided with a mounting groove 33, and a third scraper 34 is slidably connected in the mounting groove 33. A plurality of supporting springs 35 are fixedly connected on one side of the third scraper 34, and the other ends of the supporting springs 35 are fixedly connected in the mounting groove 33. A connecting groove 36 is provided on the connecting groove 36, and a connecting shaft 37 is rotatably connected in the third scraper 34.

[0030] As a preferred technical solution in this embodiment: in actual use, when the lime in the lime kiln needs to be scraped out, the staff can control the transmission motor 16 to drive the connecting platform 21 to rotate, and during the rotation of the connecting platform 21, the two first scrapers 22 can be driven to drive the second scraper 31 to rotate, so that the second scraper 31 can scrape the lime, and the lime dropped after hanging can fall into the drop pipe 13, and the staff can collect it at the drop pipe 13, and at the same time, during the rotation of the second scraper 31, the third scraper 34 can be driven. The third scraper 34 can produce a rotation effect. Since a plurality of support springs 35 are provided on the third scraper 34, it can always keep in contact with the inner wall of the conical hopper 12 under the action of the support springs 35, so that the lime in the conical hopper 12 can be scraped off effectively. At the same time, when the third scraper 34 rotates, it can drive the connecting shaft 37 to achieve a rolling effect on the inner wall of the conical hopper 12. This connection method can convert hard friction into sliding friction during use, thereby effectively ensuring that friction loss can be reduced during use, and effectively increasing its service life.

[0031] The working principle of the above embodiment is:

[0032] 1. In actual use, the staff can control the connecting seat 26 to cancel the limiting effect on the slider 24, and then the staff can control the slider 24 to produce a sliding effect in the slide groove 23. During the displacement of the slider 24, the connecting rod 27 can be driven to produce a displacement effect. During the displacement of the connecting rod 27, the scraper assembly 3 can be effectively driven to produce a rotation effect around the end of the first scraper 22. During the rotation of the scraper assembly 3, the angle between it and the first scraper 22 can be changed, so that it can adapt to conical hoppers 12 with different inclinations, effectively increasing its adaptability during use and ensuring its use effect.

[0033] 2. When the lime in the lime kiln needs to be scraped out, the staff can control the transmission motor 16 to drive the connecting platform 21 to rotate. During the rotation of the connecting platform 21, the two first scrapers 22 can be driven to drive the second scraper 31 to rotate, so that the second scraper 31 can scrape the lime, and the hung lime can fall into the drop tube 13, and the staff can collect it at the drop tube 13. At the same time, during the rotation of the second scraper 31, the third scraper 34 can be driven to rotate. Because the third scraper 34 is provided with a plurality of support springs 35, it can always keep in contact with the inner wall of the conical hopper 12 under the action of the support springs 35, so that it can scrape the lime in the conical hopper 12 well. At the same time, during the rotation of the third scraper 34, the connecting shaft 37 can be driven to roll on the inner wall of the conical hopper 12, effectively reducing its friction during use.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
