Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyor spiral structures, in particular to a high-efficiency screw conveyor spiral structure. Background Art

[0002] The spiral structure of the screw conveyor is mainly composed of spiral blades and spiral shafts. The spiral blades are the main working parts of the screw conveyor, and their shape and size directly affect the conveying effect of the material. There are many types of spiral blades, including full blade type, belt blade type, paddle blade type, tooth type, etc. Each type of spiral blade has its specific application scenario. Driven by the spiral blades, the material moves forward along the spiral shaft and is finally conveyed to the discharge port.

[0003] When in use, the spiral structure usually needs to be fixed to the conveyor by bolts and nuts. Since the spiral structure needs to convey materials, the bolts and nuts are easily exposed to dust or moisture. The dust may contain various impurities and chemicals. After these substances come into contact with the surface of the bolt, especially in a humid environment, they will form an electrochemical corrosion medium, thereby accelerating the corrosion process of the bolt. Moisture itself is also prone to cause corrosion of the bolt, especially in water containing dissolved oxygen and other corrosive substances. The corrosion rate will be faster. After corrosion, the spiral structure connection will be unstable and difficult to use, which has certain shortcomings. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a high-efficiency screw conveyor spiral structure.

[0022] Embodiment 1:

[0023] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a high-efficiency screw conveyor spiral structure, including a spiral shaft 100, a spiral blade 200, a flange 300 and a sealing assembly 400.

[0024] Specifically, the spiral shaft 100 is a hollow structure.

[0025] Specifically, the spiral blade 200 is welded to the outer side of the spiral shaft 100 , and the spiral shaft 100 can drive the spiral blade 200 to rotate. The rotating spiral blade 200 can push the material to move, so as to transport the material.

[0026] Specifically, the flange 300 is welded to both ends of the screw shaft 100. The flange 300 is provided with several mounting holes for mounting bolts and nuts. The flange 300 is a carbon steel plate. The flange 300 can increase the contact area between the screw shaft 100 and the conveyor shaft so as to be fixed by bolts and nuts.

[0027] Specifically, the sealing assembly 400 includes an inner tube 404 that is slidably connected to the spiral shaft 100, a brush 407 arranged on the inner side of the inner tube 404, a sealing shell 401 arranged on the inner tube 404, and a magnet 403 arranged on the inner side of the sealing shell 401. The magnet 403 is annular, and the sealing shell 401 is movable until the sealing shell 401 is interlaced and connected with the flange 300. After interlacing, the flange 300 can be attracted by the magnet 403 to fix the sealing shell 401. After fixation, the sealing shell 401 has a sealing effect to prevent external dust or moisture from contacting the bolts and nuts on the flange 300, thereby greatly improving the stability of the spiral structure. Then, the dust on the outside of the spiral shaft 100 can be cleaned by the brush 407 for use.

[0028] Embodiment 2:

[0029] Reference Figure 2 , which is the second embodiment of the utility model, is different from the first embodiment in that: an inclined surface 402 is provided on the inner side of the sealing shell 401, and the inclined surface 402 has a certain guiding effect, which facilitates the sealing shell 401 to be quickly inserted into the flange 300.

[0030] Embodiment three:

[0031] Reference Figure 2 , which is the third embodiment of the utility model, is different from the previous two embodiments in that: a rounded corner 405 is provided on the top of the inner tube 404, and the rounded corner 405 facilitates the movement of the inner tube 404 on the spiral shaft 100. A rubber ring 406 is provided on the inner side of the inner tube 404, and the rubber ring 406 is made of rubber, which can increase the sealing performance of the inner tube 404 for easy use.

[0032] The working principle and use process of the utility model are as follows: when in use, the flange 300 can be aligned with the rotating shaft in the conveyor, and the flange 300 can be fixed by bolts and nuts. After fixing, the sealing shell 401 of the sealing assembly 400 is moved. Since the inclined surface 402 has a guiding effect, the sealing shell 401 can be quickly inserted into the flange 300. After insertion, the flange 300 can be sucked by the magnet 403 to fix the sealing shell 401. After fixing, the sealing shell 401 has a sealing effect to prevent external dust or moisture from contacting the bolts and nuts on the flange 300, greatly improving the stability of the spiral structure. Then, the dust on the outside of the spiral shaft 100 can be cleaned by the brush wire 407 for use. During use, the sealing performance of the inner tube 404 can be increased by the rubber ring 406 for use.
