In view of the above, the invention provides a graphite boat cleaning pretreatment device, which adds an ultrasonic treatment measure before cleaning a graphite boat to remove a part of silicon nitride attached to the surface of the graphite boat, thereby reducing the consumption and emission of hydrofluoric acid in the graphite boat cleaning process, and achieving the effect of reducing the consumption and emission of industrial hydrofluoric acid.
The specific technical scheme of the invention is as follows:
a graphite boat cleaning pretreatment device is characterized by comprising an outer groove, an inner groove and a cleaning unit, wherein the inner groove is fixedly arranged in the outer groove, the cleaning unit comprises an ultrasonic vibration box, a bubbling pipe, a circulating pipe and a flow equalizing plate, and the ultrasonic vibration box is arranged at the bottom of the outer groove and is positioned between the inner groove and the outer groove; the flow equalizing plate is arranged at the bottom of the inner groove, the bubbling pipe is arranged below the flow equalizing plate, one end of the circulating pipe penetrates through the ultrasonic vibration box and is inserted into the bottom of the inner groove and is positioned below the bubbling pipe, and the other end of the circulating pipe is communicated with the outer groove, so that the cleaning liquid in the outer groove is communicated with the inner groove.
Furthermore, the plurality of bubbling tubes are uniformly and regularly arranged at the bottom of the inner groove.
Furthermore, the circulating pipe is provided with a circulating pump which provides power for the circulating exchange of the cleaning liquid of the outer tank and the inner tank.
Further, the device also comprises a liquid discharge pipe and a water injection pipe which are respectively arranged on the side wall of the outer groove.
According to the graphite boat cleaning pretreatment device, through the combined design of ultrasound, bubbling and liquid circulation, the removal of surface attachments of the graphite boat can be realized before the graphite boat is cleaned, the pretreatment is performed on the subsequent acid tank cleaning, the consumption and the discharge of hydrofluoric acid in the acid tank are effectively reduced, the overall cleaning time of the graphite boat is shortened, and the time and the economic cost in production are greatly saved.
Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
