Glass fiber insulation paper plays a vital role in the insulation effect of multi-layer insulation structure. With the continuous promotion of low-temperature insulation technology, more requirements are put forward for the performance of insulation containers. At the same time, a large amount of wastewater will be generated in the production line of low-temperature insulation paper.

The wastewater treatment device for low-temperature insulation paper production of the utility model can make the wastewater treatment process more efficient by arranging a top cover, an electric push rod, a piston and a stirring blade; by arranging a top cover, a slot and a handle, it can be convenient to clean impurities on the filter screen in the filter chamber.

[0004] However, the existing production line wastewater collection pool uses a water pump as a driving source to pump wastewater into the wastewater treatment system for sedimentation and recycling.
