球磨机给料部在线可调密封装置

Abstract

球磨机给料部在线可调密封装置，涉及球磨机技术领域，其包括固定的给料弯管和与球磨机同步转动的水平的进料管，给料弯管的一端插入所述进料管内，给料弯管的插入端外周设有凸缘，凸缘与进料管的管口内壁面相配合，进料管的管口内沿设置有台阶，台阶与凸缘之间形成环形容纳槽，环形容纳槽中卡设有密封圈，凸缘上套设有压盖，压盖的一端设有用于伸入环形容纳槽并抵住密封圈的环形凸起，给料弯管的下部外周环形设置有固定板，压盖位于固定板与进料管之间，固定板与压盖之间连接有用于调节压盖压紧力的弹性调节机构。本实用新型解决了传统密封结构因磨损导致泄漏后必须停机调整的难题，实现了密封压紧力的在线调整，保障了球磨机的连续运行。

Claims

1. An on-line adjustable seal for a ball mill feed section, characterized by: The device includes a fixed feed bend (1) and a horizontal feed pipe (2) that rotates synchronously with the ball mill. One end of the feed bend (1) is inserted into the feed pipe (2). The device is characterized by a flange (3) on the outer periphery of the inserted end of the feed bend (1), which mates with the inner wall of the feed pipe (2). A step is provided along the inner edge of the feed pipe (2), forming an annular receiving groove between the step and the flange (3). The middle card is provided with a sealing ring (4), and a pressure cap (5) is fitted on the flange (3). One end of the pressure cap (5) is provided with an annular protrusion (6) for extending into the annular receiving groove and abutting against the sealing ring (4). A fixing plate (7) is provided on the lower outer periphery of the feeding bend (1). The pressure cap (5) is located between the fixing plate (7) and the feed pipe (2). An elastic adjustment mechanism for adjusting the clamping force of the pressure cap (5) is connected between the fixing plate (7) and the pressure cap (5).

2. An on-line adjustable seal for a ball mill feed section according to claim 1, characterized in that: The elastic adjustment mechanism is a plurality of such mechanisms and is arranged in a ring at uniform intervals between the fixed plate (7) and the pressure plate (5). The elastic adjustment mechanism includes an adjustment bolt (8) threaded to the fixed plate (7). One end of the head of the adjustment bolt (8) is provided with a left guide post (9), and the pressure plate (5) is provided with a right guide post (10). The left guide post (9) and the right guide post (10) are located in the same axial direction and are spaced apart. The left guide post (9) and the right guide post (10) are fitted with compression springs (11). One end of the compression spring (11) abuts against the head of the adjustment bolt (8) and the other end abuts against the pressure plate (5). Rotating the adjustment bolt (8) can adjust the force applied by the compression spring (11) to the pressure plate (5).

3. An on-line adjustable seal for a ball mill feed section according to claim 2, characterised in that: A pad (12) for the compression spring (11) to abut is also fixed between one end of the head of the adjusting bolt (8) and the left guide post (9).

4. An on-line adjustable seal for a ball mill feed section according to any one of claims 1 to 3, characterised in that: The inner wall of the insertion end of the feed bend (1) is trumpet-shaped.

5. An on-line adjustable seal for a ball mill feed section according to any one of claims 1-3, characterized in that: The feeding bend (1) is detachably connected to the feeding trolley (13), and the upper part of the feeding trolley (13) is provided with a hopper (14) connected to the feeding end of the feeding bend (1).
