[0002] As a core component of conveying operations, the auger shaft plays an important role in many fields and occasions. The auger shaft is suitable for horizontal, inclined and vertical conveying of granular or powdery materials. Through the rotation of the spiral blades welded on the shaft, the material is continuously pushed and conveyed along a specific path. The auger shaft can not only convey conventional powdery and small lumps of materials, but also handle the conveying of materials with high viscosity or compressibility. In addition, it can also stir the mixture during the conveying process.

[0003] The auger blades of the high-strength auger shaft mechanism in the existing zinc chloride crystallization furnace are three inches in diameter. Under normal use, after about six months, prolonged twisting and tension can cause fatigue and breakage of the shaft in the upper middle position. Repairing a damaged auger shaft is time-consuming; replacing the auger after breakage requires shutdown, typically four hours. Including heating and removing substandard finished products, the time to produce finished products is generally over seven hours. After repairing and replacing the auger, the service life is generally about seven days before the welds crack and break, and the strength is insufficient. After multiple repairs and uses, the auger must be scrapped and replaced. A single auger set costs about 31,000 yuan, which is quite expensive. Utility Model Content

[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a high-strength auger shaft mechanism for a zinc chloride crystallization furnace, comprising a rotating main shaft 11, with auger blades 12 spirally wound around the outer diameter of the rotating main shaft 11. A reinforcing part is provided at the top of the rotating main shaft 11, including a connecting flange 13 located at the top of the rotating main shaft 11. A ring-shaped row of reinforcing angle plates 14 is provided at the bottom of the connecting flange 13 corresponding to the side wall of the rotating main shaft 11. A furnace cylinder 3 is provided covering the outer diameter of the auger blades 12, and zinc chloride crystals can be placed inside the furnace cylinder 3. A lifting part is installed at the top of the connecting flange 13, including a bearing cover 24 installed on the top of the connecting flange 13. The bearing cover 24 has a downwardly recessed receiving opening at its top. The furnace cylinder 3 has an upwardly protruding truncated cone 241, which can accommodate a bearing 21. The top of the truncated cone 241 has a second truncated cone 242, and the top of the second truncated cone 242 has a lifting block 23. The lifting block 23 includes a lifting hole 231, the axis of which is perpendicular to the axis of the rotating main shaft 11. The rotating main shaft 11 and the connecting flange 13 are reinforced by a reinforcing part, enabling the rotating main shaft 11 to rotate with high strength and extend its service life. The lifting hole 231 of the lifting part can lift the rotating main shaft 11 during installation or maintenance, increasing the efficiency of installation or maintenance. The auger blades 12 can rotate and lift the zinc chloride crystals inside the furnace cylinder 3. The bearing 21 can reduce friction.

[0021] Please see Figure 1 - Figure 4In this embodiment, a bearing cover lower 111 is provided on the side wall of the rotating main shaft 11 below the auger blade 12. The bottom of the bearing cover lower 111 has an annular receiving opening 112, which can accommodate a bearing 22. The bearing 22 provides some support to the rotating main shaft 11, reducing the pressure on the bearing 21. An annular stop block is provided inside the furnace cylinder 3 corresponding to the position of the bearing cover lower 111. The furnace cylinder 3 has holes corresponding to the rotating main shaft 11, allowing the bearing cover lower 111 to be inserted into the annular stop block. The top surface of the annular stop block is flush with the top surface of the bearing cover lower 111. The top of the bearing cover lower 111 has... A rubber retaining ring is provided with a raised ring at the bottom edge of the rubber retaining ring. The bottom of the raised ring contacts the top of the annular retaining ring. The bearing 22 is shielded by the cooperation of the bearing cover 111 and the annular block. The rubber retaining ring can reduce the possibility of zinc chloride crystals entering the bearing 22. The top of the furnace cylinder 3 is covered with an upper cover 41. The top of the bearing 21 can fit against the upper cover 41. The frustum 241 can pass through the upper cover 41 and protrude upward. A gear plate 422 is installed on the top of the frustum 241. The gear plate 422 is provided with a clearance hole to avoid the frustum 242. The frustum 241 passes through the upper cover 41 to facilitate the driving of the rotating main shaft 11, so that the auger blades 12 can rotate.

[0022] Please see Figure 2 - Figure 5 In this embodiment, a gear 421 meshes with the top of the gear disk 422. The axis of the gear 421 is perpendicular to the axis of the rotating main shaft 11. A geared motor 44 is provided on the side of the gear 421 away from the axis of the rotating main shaft 11. A coupling 441 is provided between the gear 421 and the geared motor 44. A mounting bracket 43 is installed on the side of the geared motor 44 near the coupling 441. The bottom of the mounting bracket 43 is fixed to the top of the upper cover 41. Through the cooperation between the gear 421 and the gear disk 422, the rotating main shaft 11 is driven to rotate, achieving the effect of automated drive. The reducer of the geared motor 44 can reduce the relative load, and the coupling 441 can protect the geared motor. Machine 44 is undamaged. The rotating main shaft 11, auger blade 12, and bearings 21 and 22 are made of stainless steel. The stainless steel rotating main shaft 11, auger blade 12, bearings 21 and 22 can improve strength and increase service life. The grade of stainless steel here is 316L. The diameter of the rotating main shaft 11 is 1.6 cm, the diameter of the auger blade 12 is d, the length of d is four inches, the thickness of the auger blade 12 on the side near the rotating main shaft 11 is a, and the length of a is six millimeters. By increasing the diameter of the shaft and the auger blade 12, the strength of the auger is improved, and the thickness of the auger blade 12 is increased to prevent the auger blade 12 from breaking.

[0023] During operation, the geared motor 44 drives the gear 421 to rotate, which in turn drives the gear disc 422 to rotate. The gear disc 422 is connected to the top of the first truncated cone 241 by screws, thus driving the first truncated cone 241 to rotate. The first truncated cone 241 drives the bearing cover 24 to rotate together. The second bearing 21 relieves the friction between the bearing cover 24 and the upper cover 41. The bottom of the bearing cover 24 is fixed with a connecting flange 13 by screws. The connecting flange 13 rotates with the bearing cover 24, thus driving the rotating main shaft 11 to rotate, so that the auger blades 12 agitate the zinc chloride crystals in the furnace tube 3. The furnace cylinder 3 has an opening on its side wall for mixing and conveying, which can be opened or closed as needed. The reinforcing angle plate 14 here bears part of the torque, making the upper part of the rotating main shaft 11 have a stronger structure and extending its service life. The combination of the rotating main shaft 11 and the auger blade 12 here forms the auger. When maintaining or installing the auger, a frame can be brought over and the hoist can be fixed to the lifting hole 231. In this way, the auger and the top cover 41 can be hoisted out together, which is convenient for inspection and maintenance. Compared with only moving or directly disassembling the top cover 41, the time is greatly shortened.

[0024] Through the above steps, the reinforcing part strengthens the connection between the rotating main shaft 11 and the connecting flange 13, enabling the rotating main shaft 11 to rotate with high strength and extend its service life. The lifting hole 231 of the hoisting part can lift the rotating main shaft 11 during installation or maintenance, increasing the efficiency of installation or maintenance. The auger blades 12 can rotate and lift the zinc chloride crystals in the furnace cylinder 3. The bearing 21 can reduce friction, thus solving the problems of low strength of the auger in the zinc chloride crystallization furnace in the prior art, easy damage, and the difficult steps of installing the auger in the sodium chloride crystallization furnace, which require a lot of time to suspend the auger.
