一种改进的钟罩式退火炉An Improved Bell-type Annealing Furnace

技术领域：Technical field:

本实用新型涉及退火炉，特别是一种改进的钟罩式退火炉。The utility model relates to an annealing furnace, in particular to an improved bell jar type annealing furnace.

背景技术：Background technique:

现有的钟罩式退火炉大多采用水冷却的方式进行冷却，由于钟罩式退火炉的热效率很高，工作时其真空内罩上会产生很大的热量，因此仅采用单一的水冷却方式进行冷却，冷却速度较慢，而且单一的水冷却方式也容易出现冷却不均的现象，这会影响炉内的冷却效果并进而波及到产品的退火性能，因而有待于改进。Most of the existing bell-jar annealing furnaces are cooled by water cooling. Due to the high thermal efficiency of the bell-jar annealing furnace, a lot of heat will be generated on the vacuum inner cover during operation, so only a single water cooling method is used. For cooling, the cooling speed is relatively slow, and the single water cooling method is also prone to uneven cooling, which will affect the cooling effect in the furnace and further affect the annealing performance of the product, so it needs to be improved.

实用新型内容：Utility model content:

本实用新型的目的在于克服上述现有技术之不足，提供一种冷却速度快、冷却效果好的钟罩式退火炉。The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a bell jar type annealing furnace with fast cooling speed and good cooling effect.

为了实现上述发明目的，本实用新型采用了以下技术方案：In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

所述风机向上倾斜的角度为10～30度。The fan is inclined upward at an angle of 10-30 degrees.

所述风机向上倾斜的角度为15度。The fan is tilted upward at an angle of 15 degrees.

所述冷却外罩的下端或底座上设有排水口，所述排水口的下方设有一与所述进水泵的进水口相连的排水槽。A drain port is provided on the lower end or the base of the cooling cover, and a drain groove connected to the water inlet of the water inlet pump is provided below the drain port.

所述真空内罩的上端设有氮气入口。The upper end of the vacuum inner cover is provided with a nitrogen inlet.

本实用新型相对于现有技术具有如下优点：Compared with the prior art, the utility model has the following advantages:

本实用新型具有冷却速度快、冷却效果好的优点。具体来说，由于采用水冷和风冷两种方式同时进行冷却，所以本实用新型钟罩式退火炉的冷却速度能得到有效提高，再加上实现风冷的两台风机对称安装在冷却外罩的下端两侧，并以向上倾斜设置的方式向炉体内吹出可循环流动的冷风，因而能确保炉体内冷却均匀，从而提高冷却效果，保证产品质量。The utility model has the advantages of fast cooling speed and good cooling effect. Specifically, since water cooling and air cooling are adopted for cooling at the same time, the cooling speed of the bell jar type annealing furnace of the utility model can be effectively improved, and the two blowers for realizing air cooling are symmetrically installed on the cooling cover. On both sides of the lower end, the circulating cold air is blown into the furnace body in an upwardly inclined manner, thus ensuring uniform cooling in the furnace body, thereby improving the cooling effect and ensuring product quality.
