摘要： Sludge removal apparatus is provided for new or existing spray coating booths, degreasing tanks, phosphate tanks, plating tanks or the like to remove sludge from the surface of a liquid in the tank. Preferably, a sludge removal tank is disposed adjacent the water holding tank of the coating booth and communicated therewith through an inlet opening. Water jets in the holding tank are directed at the inlet opening creating a current which carries floating sludge to the removal tank. Preferably, air is entrained into water and aids in floating particles. The bottoms of the tanks are preferably swept by water to remove particles settling to the bottom of the tanks. A reciprocating skimmer pushes floating sludge from the sludge removal tank up an inclined beach and into a collection bin.

摘要： A liquid level sensor for occluded water is provided to detect the surface water level as in a spray booth tank. The water level sensor may control the water level in the tank or it may be used to maintain a relatively constant outflow of water from the tank through a vertically movable weir. The weir is moved in response to changes in the liquid level detected by the sensor which includes an electronic signal sensor capable of detecting a level of a liquid relative thereto. The sensor is mounted in an elongated housing that has its lower end disposed in the liquid in the reservoir. The upper end of the housing is vented to the atmosphere to equalize the pressure between the interior thereof and the atmosphere ambient the housing. A flexible diaphragm is secured to the housing so as to seal the open lower end, and a substantially pure test liquid is held within the housing isolated from the liquid in the reservoir. The flexible diaphragm constricts or expands in response to changing liquid levels in the reservoir so that the level of the test liquid stays substantially the same as that of the level of the liquid in the reservoir. The electronic sensor measures the position of the test liquid and sends an appropriate signal to a control system that actuates the weir to raise or lower it in response to changing liquid levels in the reservoir.

摘要： Exhaust system to be used with a paint spray booth (10) and having a continuously operating power exhaust fan (20). The exhaust system has a damper (26) that is opened when spraying actively is taking place in the spray booth (10) and that is closed when there is no spraying actively taking place in the spray booth (10). A control switch (56) is mounted in any of several locations to determine when the spray gun (44) is in use or is not in use. Thus, the control switch (56) is a actuated when the spray gun (44) is hung up... indicating a nonuse condition of the spray system; whereupon use of the spray Bun (44) lifts the Bun from the hook to indicate spraying activity. A motor (32) drives the damper to the opened position; and a spring (30) biases the damper to the closed position. A timer is also used to delay the closing of the damper until between twenty and possibly two hundred seconds have lapsed after spraying activity has terminated. This purges the spray booth while yet allows for automatic damper control under normal spraying sequences of use and nonuse. A fire sensing switch (74) is used to deenergize the damper motor (32) to allow the damper (26) to be closed in the event of a fire.
摘要翻译：用于喷漆室（10）并具有连续运行的排风扇（20）的排气系统。排气系统具有阻尼器（26），当在喷雾室（10）中正在进行喷射时，打开，并且当在喷雾室（10）中不存在喷射时不闭合。控制开关（56）安装在几个位置中的任一个位置，以确定喷枪（44）何时在使用或不在使用。因此，当喷枪（44）挂起时，控制开关（56）被致动，表示喷雾系统的不使用状况; 于是使用喷雾un（（44）将钩子从挂钩上提起以指示喷洒活动。马达（32）将阻尼器驱动到打开位置; 并且弹簧（30）将阻尼器偏压到关闭位置。定时器还用于延迟阻尼器的关闭，直到在喷洒活动终止之后经过二十秒至二百秒之间。这样可以清洗喷漆室，同时允许在正常使用和不使用的喷涂顺序下进行自动风门控制。火灾传感开关（74）用于对阻尼器马达（32）进行通电，以便在发生火灾时允许阻尼器（26）关闭。
