Problems solved by technology

[0002] During the operation of the single crystal furnace, a large amount of oxides will be discharged from the furnace through the exhaust system of the furnace body. Generally, the exhaust system is designed at the bottom of the furnace, and the oxides will be transported to the exhaust pipe outside the furnace through the exhaust pipe in the furnace body and finally discharged out of the furnace. Body, in the area where the exhaust pipe in the furnace and the exhaust pipe outside the furnace are connected, is in the position where the heat and cold are transferred, and the oxides will be deposited and adsorbed here. After a long time of operation, more and more oxides will accumulate and eventually the exhaust port Blockage, leading to paralysis of the exhaust system, ultimately affecting the crystallization effect and quality

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 and 2 The structure of an embodiment of the present invention is shown, and the structure of this implementation is specifically shown. This embodiment relates to a self-purifying device for the exhaust port of a single crystal furnace. The self-purifying device for the exhaust port of a single crystal furnace is installed on the In the exhaust pipe of the furnace, it is located in the place where oxides accumulate. Clean up the oxides that are continuously deposited during the operation of the furnace body to prevent excessive accumulation of oxides from blocking the exhaust pipe, improve the efficiency of Czochralski single crystal, and improve the single crystal. crystal quality.

[0021] The above-mentioned self-purifying device for the exhaust port of the single crystal furnace, such as figure 1 and 2 As shown, it inclu...
