Title (EN) NOVEL GRINDING ROLLER SEALING DEVICE HAVING COMBINED DOUBLE SEAL
(FR) NOUVEAU DISPOSITIF D'ÉTANCHÉITÉ DE ROULEAU DE BROYAGE DOTÉ D'UN DOUBLE JOINT COMBINÉ
(ZH) 一种新型双组合磨辊密封装置
Abstract:
(EN) Provided is a novel grinding roller sealing device having a combined double seal, arranged at a connection port (10) of a rocker arm (1) of a grinding roller (9) and a housing (2). The sealing device comprises a plurality of sealing rubber strips (3), a sealing door (4), a flexible seal (5), and a curved sealing frame (6). The sealing door (4) is fixedly connected to the connection port (10) via the plurality of sealing rubber strips (3), and is a box-shaped structure having an opening. The curved sealing frame (6) is sleeved around the rocker arm (1). A curved surface of one end of the curved sealing frame (6) faces the connection port (10) and is fixedly connected to the rocker arm (1), and the other end of the curved sealing frame (6) is connected to the edge of the sealing door (4) via the flexible seal (5). The sealing door (4) and the curved sealing frame (6) are made of hard materials. The sealing door (4), the flexible seal (5), and the curved sealing frame (6) form an external sealed space (11). The sealing device uses a combination of two seals, a curved seal and flexible seal, thereby ensuring that an air leakage rate is reduced from 7% to approximately 2% regardless of the amplitude to which the grinding roller is lifted when in operation, ensures stable operation of the grinder, and improves product fineness.
(FR) L'invention concerne un nouveau dispositif d'étanchéité de rouleau de broyage doté d'un double joint combiné, disposé au niveau d'un orifice de raccordement (10) d'un bras oscillant (1) d'un rouleau de broyage (9) et d'un boîtier (2). Le dispositif d'étanchéité comprend une pluralité de bandes en caoutchouc d'étanchéité (3), une porte d'étanchéité (4), un joint souple (5) et un cadre d'étanchéité courbe (6). La porte d'étanchéité (4) est reliée de manière fixe à l'orifice de raccordement (10) par le biais de la pluralité de bandes en caoutchouc d'étanchéité (3), et elle est une structure en forme de boîte dotée d'une ouverture. Le cadre d'étanchéité courbe (6) est emmanché autour du bras oscillant (1). Une surface courbe d'une extrémité du cadre d'étanchéité courbe (6) fait face à l'orifice de raccordement (10) et elle est reliée de manière fixe au bras oscillant (1), et l'autre extrémité du cadre d'étanchéité courbe (6) est reliée au bord de la porte d'étanchéité (4) par le biais du joint souple (5). La porte d'étanchéité (4) et le cadre d'étanchéité courbe (6) sont constitués de matériaux durs. La porte d'étanchéité (4), le joint souple (5) et le cadre d'étanchéité courbe (6) forment un espace étanche externe (11). Le dispositif d'étanchéité utilise une combinaison de deux joints, un joint courbe et un joint souple, ce qui garantit une réduction d'un taux de fuite d'air de 7 % à environ 2 % indépendamment de l'amplitude de laquelle le rouleau de broyage est soulevé lors du fonctionnement, garantit un fonctionnement stable du broyeur et améliore la finesse du produit.
(ZH) 一种新型双组合磨辊密封装置,设置于磨辊(9)的摇臂(1)与壳体(2)的连接口(10)处,密封装置包括若干密封胶条(3)、密封门(4)、柔性密封(5)和弧形密封架(6);密封门(4)通过若干密封胶条(3)固定连接在接口(10)处,并且密封门(4)为开口的盒体形结构;弧形密封架(6)套在摇臂(1)上,并且弧形密封架(6)的一端弧面朝向连接口(10)且固定连接在摇臂(1)上,弧形密封架(6)的另一端与密封门(4)的边缘处通过柔性密封(5)连接;密封门(4)和弧形密封架(6)由硬质材料制成,密封门(4)、柔性密封(5)和弧形密封架(6)围成外部密封空间(11)。该密封装置采用弧形密封和柔性密封两种密封的组合使用,保证磨辊在运转过程中,不管抬辊幅度大小,均能将漏风率由7%降到2%左右,为磨机的连续稳定运行,产品细度的提高提供保证。
