具体实施方式Detailed ways
结合附图对本实用新型的具体实施方式进行说明。The specific embodiment of the utility model will be described in conjunction with the accompanying drawings.
如图1，本环锤式破碎机转子轴端密封结构，包括环锤式破碎机壳体侧板1、转子轴2和通过螺纹连接装配在转子轴2上的转子圆盘3。在所述转子圆盘3的外侧端焊接一与该转子圆盘3同轴心的挡风环4，该挡风环4随转子旋转。在所述壳体侧板1的外侧面通过螺钉连接安装一中心设有圆孔的固定板5，该固定板5的中心圆孔处设有密封套6，该密封套6的外侧设有连接法兰并通过该法兰固定连接在固定板5的外侧面上，该密封套6的内侧部通过所述固定板5的中心圆孔且其内侧端伸入到所述的挡风环4内，并形成挡风环4内径面与密封套6外径面的间隙配合结构。密封套6的内径面设有盘根环槽，在该盘根环槽与转子轴2轴面间形成的填料腔内设有盘根7，盘根7可采用高水基芳纶盘根。盘根7的外侧设有盘根压盖8，该盘根压盖8通过其外侧设置的法兰与所述的密封套6固定连接。As shown in Fig. 1, the sealing structure of the rotor shaft end of the ring hammer crusher includes the side plate 1 of the ring hammer crusher shell, the rotor shaft 2 and the rotor disc 3 assembled on the rotor shaft 2 through threaded connection. A windshield ring 4 coaxial with the rotor disk 3 is welded to the outer end of the rotor disk 3, and the windshield ring 4 rotates with the rotor. On the outer surface of the housing side plate 1, a fixed plate 5 with a round hole is installed in the center through screw connection. The central round hole of the fixed plate 5 is provided with a sealing sleeve 6, and the outer side of the sealing sleeve 6 is provided with a connecting ring. The flange is fixedly connected to the outer surface of the fixed plate 5 through the flange, the inner side of the sealing sleeve 6 passes through the central circular hole of the fixed plate 5 and its inner end extends into the windshield ring 4 , and form a clearance fit structure between the inner diameter surface of the windshield ring 4 and the outer diameter surface of the seal sleeve 6 . The inner diameter surface of the sealing sleeve 6 is provided with a packing ring groove, and a packing 7 is arranged in the packing cavity formed between the packing ring groove and the axial surface of the rotor shaft 2, and the packing 7 can be made of high water-based aramid fiber packing. A packing gland 8 is provided on the outer side of the packing 7, and the packing gland 8 is fixedly connected to the sealing sleeve 6 through a flange provided on the outer side thereof.
如图2，本环锤式破碎机转子轴端密封结构的固定板5、密封套6、盘根压盖8适合设置成两半体组合结构，便于安装更换。如附图实施例，固定板5采用搭接两半体组合结构，密封套6、盘根压盖8采用对接两半体组合结构。As shown in Fig. 2, the fixed plate 5, sealing sleeve 6, and packing gland 8 of the rotor shaft end sealing structure of the ring hammer crusher are suitable to be arranged in a combined structure of two halves, which is convenient for installation and replacement. As shown in the accompanying drawings, the fixed plate 5 adopts a combined structure of two overlapping halves, and the sealing sleeve 6 and packing gland 8 adopt a combined structure of two butted halves.
本环锤式破碎机转子轴端密封结构用于环锤式破碎机中，当转子旋转，在环锤式破碎机内部产生的粉尘首先受到挡风环的第一道阻挡，再受到高水基芳纶盘根第二道阻挡，实现转子轴端的有效密封，并达到有效阻止粉尘泄露的目的。同时挡风环的存在有效降低了粉尘对盘根密封的不良影响，大大提高了盘根密封的工作寿命和可靠性。The ring hammer crusher rotor shaft end sealing structure is used in the ring hammer crusher. When the rotor rotates, the dust generated inside the ring hammer crusher is first blocked by the first windshield ring, and then by the high water-based aramid fiber. The second barrier of the packing realizes the effective sealing of the rotor shaft end and effectively prevents the leakage of dust. At the same time, the existence of the windshield ring effectively reduces the adverse effect of dust on the packing seal, and greatly improves the working life and reliability of the packing seal.
