Dust collector and material level survey device

The utility model discloses a dust collector and material level survey device, dust collector includes air supply pipe (1) and sweeps tub (2) that the export that sweeps tub entry of (2) and air supply pipe (1) links to each other, sweeps export corresponding charge level indicator (3) the setting of tub (2). The utility model provides a dust collector can pass through compressed air air supply pipe (1) and sweep tub (2) to blow to the charge level indicator to blow away the material of adhesion on charge level indicator (3), avoid charge level indicator (3) false value or wrong report to appear, simultaneously, adopt this kind of dust collector can also reduce artificial input, reduce the potential safety hazard. 本实用新型公开了种除尘装置以及种料位测定装置，所述除尘装置包括气源管(1)和吹扫管(2)，吹扫管(2)的入口与气源管(1)的出口相连，吹扫管(2)的出口对应料位计(3)设置。本实用新型提供的除尘装置能将压缩空气通过气源管(1)和吹扫管(2)向料位计吹送，从而吹走粘附在料位计(3)上的物料，避免料位计(3)出现虚假值或者误报，同时，采用该种除尘装置还能减少人工的投入，减少安全隐患。
