Description

Technical Field

[0001] This utility model belongs to the technical field of bag-in-bag-out high-efficiency filtration equipment (BIBO for short), and specifically relates to an external sensor mounting structure for a BIBO scanning device. Background Technology

[0002] Currently, automatic in-situ scanning leak detection BIBO equipment is very common. Its transmission structure is mostly a motor driving a lead screw to rotate, thereby driving the reciprocating scanning head assembly to move back and forth in the BIBO box to realize the leak detection function of the scanning head. This structure requires position sensors to be arranged at the front and rear to limit the range of motion of the scanning head to reciprocate and change direction.

[0003] Currently, the common approach is to directly embed the sensor inside the enclosure, with the power cord leading out of the enclosure via an aviation connector. This approach has several drawbacks: firstly, the aviation connector may leak, affecting the airtightness of the enclosure; secondly, when disinfecting inside the BIBO enclosure, the disinfectant may corrode the sensor surface, affecting the accuracy of automatic scanning; and thirdly, the sensor power cord connector may also be corroded.

[0010] Preferably, the outer box and the inner box are slidably connected and separated at one end by a ball-and-pin buckle assembly.
