In the structure, an overflow hole is formed between the lower end of the overflow baffle and the inner wall of the bottom of the inner cavity of the overflow cavity.
Compared with the prior art, the utility model, following positive effect has:
1. the utility model discloses horizontal installation does not receive the restriction of overall system overall arrangement.
2. The utility model discloses a horizontal structure, the liquid cargo volume of gathering is more, is applicable to the big latus rectum pipeline.
3. The trace overflow in the inner cavity of the overflow cavity flows into the collection cabin through an overflow hole at the bottom of the overflow baffle; liquid goods that alarm state overflow was saved then through the overflow hole of overflow baffle bottom, if the liquid goods of saving when higher overflow baffle, still directly spill over from the overflow baffle, flow into and collect the under-deck to ensure entire system's normal operating, realize liquid goods overflow control.
