The invention discloses a device used for producing a quartz glass crucible. The device comprises a frame body, a clamping mechanism, a containing plate and a spraying mechanism. The frame body comprises a bottom plate and supporting plates symmetrically and fixedly connected to the upper surface of the bottom plate. The clamping mechanism is connected between the supporting plates in a sliding manner. The clamping mechanism comprises a lifting plate, a base plate and a threaded rod. The containing plate is arranged between the supporting plates and located below the clamping mechanism. The spraying mechanism comprises a water tank, a spraying main pipe, a motor and a high-pressure water pump. The device has the beneficial effects that by arranging the clamping mechanism, reliable clampingcan be provided for the crucible through the clamping mechanism in the spraying process, it is avoided that the crucible irregularly moves in the spraying process, and therefore the spraying effect is improved, and generation of spraying small holes is reduced; and in the process, water used for spraying can be recycled after being filtered, and therefore unnecessary waste of water resources is effectively reduced.
