The utility model discloses an
impurity removal device for
tin stripping
wastewater recovery, which relates to the technical field of
tin stripping
wastewater recovery and comprises a base frame, an
impurity removal box is obliquely arranged at the top of the base frame from top to bottom, a liquid
discharge hopper is arranged at the bottom end of the
impurity removal box, and a side wall
pipe is arranged at the connecting end of the impurity removal box and the liquid
discharge hopper in a surrounding manner. A plurality of groups of liquid outlet holes distributed at intervals are formed in the inner wall of the side wall
pipe, in the waste liquid impurity removal process, waste liquid can be pumped out of the
tin liquid box in a pressurized mode through the pressure pump, the waste liquid is conveyed into the side wall
pipe through the three-way pipe and the main flow hose, the waste liquid can be guided to the side wall of the liquid drainage hopper through the liquid outlet holes formed in the side wall pipe, and the waste liquid can be discharged out of the side wall of the liquid drainage hopper. By means of the device, the tin-
lead alloy coating film fragments attached to the side wall of the liquid discharging hopper can be washed and cleaned, the device can wash the film fragments attached to the interior of the device while waste liquid impurity removal is conducted, the follow-up cleaning
workload is greatly reduced, and the operation burden of workers is relieved.
