Spraying apparatus for cleaning filter plates

Image Number 11 for United States Patent #4448221.

Spraying apparatus for cleaning filter plates embodies a support frame which is mounted for movement beneath the filter plates and is adapted to align with each space formed between adjacent filter plates to be cleaned. A spraying unit is mounted for pivotal movement on the support frame selectively to a lowered position beneath the filter plates and to a raised position extending upwardly into the space between adjacent filter plates. A spray dispenser carried by the spraying unit moves within the space to apply spray to the adjacent vertical surfaces of the filter plates being cleaned.
