Description

Exhaust device of single crystal furnace Technical Field The utility model relates to the technical field of single crystal bar production, in particular to an exhaust device of a single crystal furnace. Background After the single crystal furnace is used for drawing the single crystal rod, residual gas and tiny dust in the equipment are removed through an exhaust device in the furnace cooling process, so that heat in the furnace is rapidly removed, the clean environment of a workshop is purified, and the furnace cooling process of the equipment is improved. In the cooling process, the air outlet of the air exhaust device needs to be moved to the upper part of the upper opening of the single crystal furnace. The existing exhaust device has fixed air outlet height, different furnace top and bottom edges exist, on one hand, the exhaust device is easy to rub with part of the upper opening of the single crystal furnace in the moving process to damage the sealing surface, and on the other hand, the exhaust device is far away from the part of the upper opening of the single crystal furnace, so that the cooling time is long. Disclosure of utility model Aiming at the problems, the utility model provides a single crystal furnace wind discharging device, which comprises the following specific technical scheme: A single crystal furnace ventilation device comprises a support, a branch exhaust pipe, a main exhaust pipe, a screw and a fan cover, wherein the branch exhaust pipe is arranged on the upper side of the support, one end of the branch exhaust pipe is connected with a vertically arranged hose, the other end of the branch exhaust pipe is connected to the main exhaust pipe, the fan cover is arranged on the lower side of the hose, a cross beam is arranged in the fan cover, the screw is overlapped with the axis of the hose, the screw is in threaded connection with the branch exhaust pipe, the screw is in rotary connection with the cross beam, two limiting bosses are further arranged on the screw, and the cross beam is clamped between the two limiting bosses. Further, the hose is a bellows. Furthermore, the lower side of the bracket is provided with a universal wheel, and the universal wheel is provided with a brake pad. Further, the upper end of the screw rod is also connected with a rotary handle. Further, a through hole is formed in the branch exhaust pipe, a nut is arranged above the through hole, and a screw rod penetrates through the nut and the through hole and then is connected with the cross beam. The utility model has the beneficial effects that: The height of the fan housing is adjusted through the screw, so that a reasonable gap is kept between the fan housing and the upper opening of the single crystal furnace, thorough exhaust is facilitated, meanwhile, scraping and rubbing between the sealing surface of the upper opening of the single crystal furnace and the fan housing are avoided, maintenance frequency of the single crystal furnace is reduced, production cost is reduced, and production efficiency is improved.
