Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcining furnaces, and in particular to a novel active lime calcining furnace. Background Technology
[0002] Active lime, also known as soft calcined lime, refers to lime calcined in the range of 920℃ to 1200℃. Its characteristics include a porosity of up to 40%, a sponge-like texture, a low bulk density of 1.7 to 2.0 g / cm³, a large specific surface area of 0.5 to 1.3 m² / g, and fine lime crystals, resulting in high melting capacity during slag formation.
[0003] In order to ensure the uniformity of feeding and calcination, existing quicklime calcining furnaces often use a screening structure to screen the feed. However, this method has the following problems:
[0004] During the screening process, lime with uniform particles enters the furnace for calcination, while lime with uneven particles is concentrated on the screening structure. Existing calcination furnaces cannot quickly process this part of the lime, and it is necessary to manually remove it after screening for secondary crushing, which affects the calcination efficiency.
[0005] Therefore, this utility model proposes a novel active lime calcining furnace. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a novel active lime calcining furnace technical solution: it includes a first main body 1 and a second main body 2 with matching configurations. A guide plate 3 is fixedly connected to the top of the first main body 1, and a screening component 4 and a grinding component 5 are connected inside the first main body 1.
[0024] The screening component 4 includes a screen plate 6 and a mounting base 7 that are fixedly connected. A back plate 9 is fixedly connected to the bottom outer side of the mounting base 7. A drive shaft 8 is provided through the mounting base 7. The grinding component 5 includes a mounting frame 10 and a grinding disc 11 on its surface. A feed cylinder 12 is fixedly connected to the bottom end of the grinding disc 11. A grinding column 13 is movably arranged above the grinding disc 11. A drive base 14 is fixedly connected to the top of the grinding column 13. A drive disc 15 is matchedly connected to the top of the drive base 14.
[0025] like Figure 1-2 As shown, the guide plate 3 is vertically arranged in a "Z" shape. The first main body 1 and the second main body 2 are connected. The top of the first main body 1 has an inlet. The outer end of the screen plate 6 is rotated and set inside the first main body 1 on one side via the drive shaft 8. It is staggered with the guide plate 3. The mounting base 7 and the back plate 9 are both attached to one side of the inner wall of the first main body 1. The two ends of the drive shaft 8 are movably set through the inner wall of the first main body 1. The outer end of the drive shaft 8 is also equipped with a drive motor. The drive shaft 8 drives the screen plate 6 to rotate and adjust inside the first main body 1. The screen plate 6 is used to screen the external lime entering the first main body 1.
[0026] External lime enters the first body 1 and is guided to the screening component 4 via the guide plate 3. The screen plate 6 in the screening component 4 screens the lime. The uniformly screened lime falls through the screen plate 6 and is collected in the second body 2 for subsequent calcination treatment, while the screened uneven lime is inclinedly guided along the screen plate 6 to the grinding component 5 for grinding treatment.
[0027] like Figure 3-4 As shown, the mounting frame 10 is L-shaped, with a limiting cavity in the center of its surface corresponding to the feeding cylinder 12. The grinding disc 11 is fixedly mounted on the surface of the mounting frame 10, and its surface is concave in an arc shape. A feeding opening is provided in the center of the inner surface of the grinding disc 11 corresponding to the feeding cylinder 12. The grinding column 13 is inclined, and its bottom end is movably embedded in the feeding opening on the inner surface of the grinding disc 11. The drive seat 14 is composed of two sets of rectangular seats connected in a staggered manner. A connecting shaft is provided between the drive seat 14 and the drive disc 15. A drive motor is provided on the top of the drive disc 15. The drive disc 15 drives the drive seat 14 to rotate, and the drive seat 14 drives the grinding column 13 to rotate eccentrically. The grinding column 13 grinds the lime in the grinding disc 11, and the feeding cylinder 12 discharges the ground lime.
[0028] The screened uneven particles fall along the sieve plate 6 and are concentrated in the grinding disc 11. At this time, the drive disc 15 rotates, and under the action of the drive seat 14, the grinding column 13 is driven to rotate eccentrically along the grinding opening on the inner surface of the grinding disc 11 to grind the lime. The ground lime falls along the feed cylinder 12 to the second body 2 for subsequent calcination.
[0029] The working principle of this utility model is as follows: When this device is in use, it can simultaneously grind the uneven lime selected by screening through the grinding component 5, so that the screened lime can be calcined in one go, which greatly improves the calcination efficiency of the calcining furnace.
