Batch feeding and discharging system and method for continuous production type vacuum atmosphere furnace

Abstract

The invention discloses a batch feeding and discharging system and a batch feeding and discharging method. The system comprises a feeding device and a discharging device, wherein the feeding device comprises a multi-layer carrier holder I, and also comprises a motor I, and the motor I can drive a lead screw mechanism I to drive the carrier holder I of the feeding device to move up and down; and the discharging device also comprises a multi-layer carrier holder II, and also comprises a motor II which not only can drive a lead screw mechanism II to drive the carrier holder II of the discharging device to move up and down, but also can drive a gear and rack mechanism to drive the carrier holder II of the discharging device to make horizontal movement, and the layer number of the holder II is the same as that of the holder I. Through the batch feeding and discharging system disclosed by the invention, the continuous production of a multi-chamber vacuum atmosphere furnace is realized, and the situation that the continuous vacuuming is needed in the charging and taking process in the traditional vacuum atmosphere furnace can be avoided, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a batch feeding and discharging system in heat treatment, in particular to a batch feeding and discharging system for continuous production of nanometer materials and vacuum atmosphere heat treatment workpieces, and a batch feeding and discharging method using the system. Background technique [0002] The vacuum atmosphere furnace appeared in the 1920s. In 1986, Germany developed and produced the first gas-fired vacuum furnace. For decades, hundreds to thousands of gas-fired vacuum furnaces have been used in production. Due to the wide application of graphite materials and the urgent needs of aerospace, electronics and other industries, it has developed rapidly. Various types of vacuum furnaces have appeared, and they are constantly developing in the direction of automation, large-scale and continuous. Among them, the production line of sealed multi-purpose furnace and continuous furnace has a high degree of automation, strong ...

Problems solved by technology

The patent number is "200510104486.4" and the name is "three-chamber intelligent periodic controllable atmosphere furnace". It is a typical three-chamber continuous production controllable vacuum atmosphere furnace. The linear track design is adopted, and the material in and out is realized through the movement of the material box on the track. The feeding chamber and the discharging chamber of this atmosphere furnace can only accommodate one material box. After the production of each furnace is completed, the furnace door of the feeding room must be opened to load the next For one material box, open the furnace door of the discharge chamber to take out the previous material box. The process of loading and unloading requires constant vacuuming, which not only reduces production efficiency, but also wastes a lot of protective gas

In addition, most of the feeding and discharging devices widely used in the heat treatment industry are open mesh belts or external feeding trolleys, which are not suitable for the batch feeding and discharging requirements of multi-chamber vacuum furnaces due to material and structure limitations, such as mesh belt furnaces, which are widely used, The patent number is "200920187620.5" and the name is "a linear material conveying device" and the patent number is "201010615412.8" and the name is "a heavy-duty feeding trolley device for a large horizontal heat treatment furnace"
