Appl. No.:

8/547654

International Classification:

B08B 302

US Classification:

134 63

Abstract:

An oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles to spray a printing screen. An oscillating mechanism moves the screen in an oscillating motion in front of the spray nozzles for efficient and effective cleaning. Fixed guide brackets extend into the cleaning chamber from the spray nozzles to guide a screen and maintain the screen perpendicular to the spray patterns from the nozzles. The guide brackets will readily guide screens of different widths and heights without requiring constant adaptation. A reservoir is integrated with the enclosed cleaning chamber and a sloped wall captures spray from the cleaning chamber and directs it to the reservoir for recycling. A vertically oriented pump in the reservoir directs cleaning liquid to the spray nozzles and any failure of the pump is contained in the reservoir to prevent leakage. A wipe down booth is coupled to the cleaning chamber and captures excess cleaning liquid after the screen is removed from the cleaning chamber and directs to the captured liquid back into the reservoir.

US Classification:

Abstract:

An oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles positioned therein to spray a printing screen with cleaning solvent. An oscillating mechanism is mounted within the cleaning chamber to move the screen in an oscillating motion in front of the spray nozzles to provide an efficient and effective cleaning of the printing screen. The spray nozzles are arranged in two opposing grid patterns and the screen is oscillated between the grid patterns to provide complete coverage of the screen with spray cleaning solvent. The sprayed solvent is collected, filtered and resprayed onto the screen, and the high spray rate of the apparatus ensures effective cleaning with the re-used solvent. The entire spray system is enclosed within a housing which is coupled to a vapor recovery system so that solvent and solvent vapors do not escape into the environment. The apparatus provides rapid and efficient cleaning of the printing screen with cost-effective re-use of the solvent and contaminant of the solvent to produce a safer work environment.

Intercontinental Chemical Corporation

International Classification:

B08B 302

US Classification:

134 15

Abstract:

A printing screen cleaning and reclaiming apparatus comprises a cleaning device defining a cleaning and reclaiming path and a plurality of low pressure-high volume water washoff stations, in series, along the path. An ink degradent, an emulsion remover, and a degreaser are each applied successively along the path, and an ink removal station, an emulsion removal station, and a degreaser removal station are positioned successively along the path to provide the low pressure-high volume water washoff. Each station is capable of delivering washoff fluid to the screen of up to 20 feet in height and any length in the range of approximately 40-400 psi, and in the range of approximately 10-250 gallons per minute for efficient and inexpensive cleaning of the screen.
