The field of graphite heater preparation relates in particular to a tantalum foil pretreatment device for graphite heater preparation of a single crystal furnace. The technical problem to be solved is to provide a tantalum foil pretreatment device for preparing graphite heater of a single crystal furnace. The technical scheme of the invention comprises a tantalum foil pretreatment device for preparing a graphite heater of a single crystal furnace, which comprises a bottom frame, a controller, a pickling box, a pickling auxiliary component, an acid cleaning component and a washing component; The acid cleaning assembly is connected with the washing assembly. When used, the invention realizes that when pickling a stack of tantalum foil, the tantalum foil can swing in the acid and create an interval between the layers of tantalum foil, so as to fully carry out pickling. After pickling, the acid in the tantalum foil layer can be squeezed out and recovered to improve the pickling effect and save resources at the same time. When washing, the tantalum foil can swing and spray water column on the side at the same time to fully wash the tantalum foil.
In order to solve the problem in the prior art, during the pre-treatment of a stack of tantalum foams, a stack of tantalum foams cannot be fully pickled due to the mutual bonding of each layer of tantalum foams, and after pickling, when a stack of tantalum foams are removed from the pickling solution, the tantalum foil interlayer contains a large amount of acid, which requires a lot of time to wait for the pickling to drop off. If the acid is wasted and a large amount of water is needed to be diluted to achieve the washing effect, the tantalum foil stack can not be fully washed during washing.
Pickling auxiliary components, acid cleaning components and washing components are designed. When preparing for work, the device is placed on the horizontal surface, the power is switched on, a stack of tantalum foil is put into the pickling auxiliary component on the bottom shelf, and the pickling auxiliary component is controlled by the controller to put tantalum foil into the pickling tank for pickling. After pickling, the surface of tantalum foil and the acid in the interlayer are cleaned with the acid cleaning component. The pickling auxiliary component then delivers the tantalum foil to the washing component for washing.
When used, when pickling a stack of tantalum foil, the tantalum foil is made to swing in the acid to create an interval between the layers of tantalum foil, so as to fully carry out pickling. After pickling, the acid in the tantalum foil layer is squeezed out and recovered to improve the pickling effect and save resources. When washing, the tantalum foil is made to swing and spray water column on the side to fully wash the tantalum foil.
