Description

Technical Field

[0001] This utility model belongs to the field of digester technology, and in particular relates to a stirring mechanism of a combined lime digester. Background Technology

[0002] Existing lime digesters mainly consist of a power unit, filter screen, roller ring, cylinder, gear ring, and support roller device. The cylinder is divided into four zones: buffer zone, digestion zone, homogenization zone, and slag separation zone. A slag removal and discharge device is installed at the tail end. Quicklime blocks absorb water and digest in the cylinder, and lime slurry flows out through the drain outlet after passing through the screen holes. Undigested overburned quicklime, stones, and impurities are discharged at the tail end. However, existing lime digesters have the problem of insufficient digestion of lime slurry. A combined lime digester needs to be designed to meet the usage requirements, and the design of the stirring mechanism is particularly important. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a stirring mechanism for a combined lime digester that is simple and reliable in structure and can ensure that the digestion reaction is fully carried out.

[0004] A mixing mechanism for a combined lime slaking machine includes a rotating shaft. A pushing device, a mixing device, and a feeding device are sequentially arranged along the length of the rotating shaft. The pushing device includes multiple support bars, which are fixedly connected to the rotating shaft. The multiple support bars are arranged in a ring around the rotating shaft, and a pushing spiral blade is fixedly attached to the multiple support bars.

[0013] This utility model has a reasonable structural design. The segmented structure of the stirring mechanism facilitates the full reaction and digestion of lime and water.

Detailed Implementation

[0020] like Figure 1-3 As shown, a mixing mechanism of a combined lime digester includes a rotating shaft 301, and a pushing device, a mixing device and a feeding device are arranged sequentially along the length of the rotating shaft 301.

[0021] With this design, the rotating shaft 301 drives the pushing device, stirring device and material feeding device to rotate, which facilitates the full reaction and digestion of lime and water. The pushing device can not only stir and mix lime and water, but also push lime and water to the stirring device and material feeding device. The material feeding device can transfer lime slag and insufficiently reacted lime to the slag lifting machine 5.

[0022] The feeding device includes three support bars 302, which are fixedly connected to the rotating shaft 301. The three support bars 302 are arranged in a ring around the rotating shaft 301, and feeding spiral blades 303 are fixedly connected to the three support bars 302.

[0023] With this design, the pusher screw blade 303 rotates with the rotating shaft 301, which facilitates the thorough mixing of lime and water. During the rotation of the pusher screw blade 303, it can push the lime and water towards the mixing device and the feeding device. The support bar 302 creates a channel between the pusher screw blade 303 and the rotating shaft 301 to facilitate the circulation of water.

[0024] In addition to this embodiment, the number of support bars 302 can be more than three.

[0025] The stirring device includes seven stirring components, which are fixedly connected to the rotating shaft 301. The seven stirring components are arranged in a spiral around the rotating shaft 301.

[0026] This design further improves the mixing effect of lime and water.

[0027] In addition to this embodiment, the number of stirring components can also be two, three, four, five, six, or seven or more.

[0028] The stirring assembly includes two first half supports 304, which are respectively disposed on both sides of the rotating shaft 301 and fixedly connected thereto. Support plates 305 are fixedly connected to the two first half supports 304 on the side away from each other. An agitator plate 306 is detachably fixed to one side of the support plate 305 by bolts.

[0029] The two stirring plates 306 are arranged at an angle.

[0030] The included angle α between the two stirring plates 306 is 60±1°.

[0031] This design allows for more thorough mixing of lime and water.

[0032] Both sides of the support plate 305 are fixedly connected to the reinforcing plate 307, and the reinforcing plate 307 is fixedly connected to its corresponding first half support 304, thereby increasing the strength of the stirring assembly.

[0033] The feeding device includes two feeding components, which are respectively located on both sides of the rotating shaft 301 and fixedly connected to it.

[0034] The two feeding components are arranged symmetrically.

[0035] The feeding assembly includes two second half supports 308, which are fixedly connected to the rotating shaft 301. The two second half supports 308 are spaced apart along the length of the rotating shaft 301. A connecting plate 309 is fixedly connected to the side of each second half support 308 away from the rotating shaft 301. A feeding plate 310 is fixedly connected to the end of each connecting plate 309 away from the rotating shaft 301.

[0036] like Figure 4 As shown, the stirring mechanism is installed in the digestion box 2 of the combined lime digester. The rotating shaft 301 is rotatably connected to the digestion box 2. The driving device 4 drives the rotating shaft 301 to rotate. The digestion box 2 and the driving device 4 are fixedly installed above the base 1. A slag lifter 5 is fixedly installed on one side of the digestion box 2.

[0037] A feeding hopper 201 is provided on the top surface of the digester 2 near one end. A pushing device is close to the feeding hopper 201, and a feeding device is away from the feeding hopper 201.

[0038] In use, lime and water enter the digestion tank 2 from the feed hopper 201. The pushing device pushes the lime and water towards the stirring device and the feeding device. The segmented stirring mechanism rotates to make the lime and water fully contact and react to form an emulsion. The feeding device transfers the lime slag and unreacted lime in the digestion tank 2 to the slag lifter 5 for a secondary digestion reaction. The slag lifter 5 separates the emulsion and lime slag and discharges them.

[0039] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
