[0002] Powder classifiers are widely used in coal mills, raw material intermediate unloading drying mills and cement mill systems in new dry process cement production lines. They can be divided into three categories: three-separation powder classifiers, centrifugal powder classifiers and cyclone powder classifiers.
[0003] Among them, the powder classifier is equipped with annular static blades, but the existing annular blades are all set as an integrated structure. When the annular static blades are damaged, the staff is required to replace the static blades as a whole. This is not only inconvenient for maintenance, but also increases the maintenance cost. For this reason, we propose a special-shaped blade to solve the above problem. Utility Model Content

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0019] Embodiment 1:
[0020] like Figure 1-Figure 2 As shown, a special-shaped blade comprises an upper mounting ring 100 and a lower mounting ring 101, a plurality of special-shaped leaves 102 are evenly distributed between the upper mounting ring 100 and the lower mounting ring 101, a first locking assembly is provided between the upper mounting ring 100 and each special-shaped leaf 102, and a second locking assembly is provided between the lower mounting ring 101 and each special-shaped leaf 102;
[0021] The second locking assembly includes a plurality of blocks 103. A groove 104 is provided at the upper end of the lower mounting ring 101. Matching mounting rings 105 are provided inside the groove 104. Each block 103 is arranged inside the groove 104. A corresponding through hole 106 is provided at the upper end of the mounting ring 105. Threaded rods 107 are provided at the upper and lower ends of each special-shaped leaf 102. One end of the lower threaded rod 107 passes through the through hole 106 and is threadedly connected to any block 103. A limiting assembly is provided between the mounting ring 105 and the lower wall of the groove 104.
[0022] The upper mounting ring 100, the lower mounting ring 101 and the various shaped leaves 102 together form an annular static blade. After each clamping block 103 is placed in the groove 104, the threaded rod 107 on the lower side can be threadedly connected to the clamping block 103. The mounting ring 105 can make it easier to put the clamping block 103 into the groove 104. The through hole 106 facilitates the insertion of the threaded rod 107 and connects with the clamping block 103. The limiting component can limit the movement of the clamping block 103 to prevent the angle of each shaped leaf 102 from being problematic, thereby affecting the normal use of the powder classifier.
[0023] When any of the special-shaped leaves 102 is damaged: first release the first locking assembly so that the upper threaded rod 107 can be taken out first, then rotate the damaged special-shaped leaf 102 so that the special-shaped leaf 102 and the corresponding clamping block 103 are released, and finally the new special-shaped leaf 102 is synchronized with the above operation, so that the purpose of quickly replacing the special-shaped leaf 102 can be achieved, and at the same time, the special-shaped leaf 102 can be avoided from being replaced as a whole, saving maintenance costs;
[0024] In this embodiment, by releasing the first locking assembly and rotating the special-shaped leaf 102, the threaded rod 107 on the lower side can be disconnected from the corresponding block 103, thereby achieving the purpose of quickly disassembling a single special-shaped leaf 102. At the same time, it is also convenient to install any special-shaped leaf 102, avoiding the overall replacement of the special-shaped leaf 102 and wasting maintenance costs.
[0025] Embodiment 2:
[0026] Based on the first embodiment, other components on the special-shaped blade are further described, such as Figure 1-Figure 2 As shown, the limiting assembly includes a plurality of plug-in boards 200 , each of which is evenly distributed and fixed on the lower wall of the groove 104 , and any block 103 is arranged between two adjacent plug-in boards 200 , and a socket 201 matching each of the plug-in boards 200 is provided at the lower end of the mounting ring 105 .
[0027] The first locking assembly includes a plurality of sleeves 202 . A plurality of evenly distributed mounting holes 203 are formed at the upper end of the upper mounting ring 100 . Each threaded rod 107 on the upper side is disposed inside the corresponding mounting hole 203 . Each sleeve 202 is threadedly connected to the corresponding threaded rod 107 .
[0028] A screw cap 204 is disposed at the upper end of each sleeve 202 .
[0029] A placement opening 205 is provided on the outer side of the upper mounting ring 100 , and a mounting hole 203 is provided on one side of the outer surface of the placement opening.
[0030] In this embodiment, when the mounting ring 105 is inserted into the groove 104, each socket 201 is also inserted into the outer side of each corresponding plug board 200, so as to prevent each block 103 from being offset, affecting the angle of installing each special-shaped leaf 102, thereby indirectly affecting the use of the powder selection machine;
[0031] Since the placement opening 205 allows the staff to directly insert the upper threaded rod 107 into the upper mounting ring 100, and then directly insert the sleeve 202 into the mounting hole 203, and screw the screw cover 204, the upper threaded rods 107 can be fixed together with the upper mounting ring 100, thereby facilitating the staff to replace a single special-shaped leaf 102.
[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
