Vertical and horizontal efficient energy-saving vacuum controlled atmosphere furnace for continuous production

Abstract

The invention aims to provide a vertical and horizontal efficient energy-saving vacuum controlled atmosphere furnace for continuous production with high space utilization rate, high heating speed, high product cooling speed, short production period and avoidance of great energy waste caused by repeated heating and cooling during production. The furnace consists of a feeding chamber, a reaction chamber and a discharge chamber, wherein the feeding chamber is positioned below the reaction chamber, and the feeding chamber and the reaction chamber form a vertical structure; and the discharge chamber is positioned on the lateral surface of the reaction chamber, and the discharge chamber and the reaction chamber form a horizontal structure so as to form a vertical and horizontal structure and improve the space utilization rate. The furnace realizes heat insulation and seal of each chamber by adopting a heat insulation sealing door, and has high heating speed and high energy efficiency by adopting an inductive heating mode; the product is cooled by adopting a circulating air cooling system; and the vertical and horizontal efficient energy-saving vacuum controlled atmosphere furnace for continuous production can perform continuous production only by one-time heating so as to improve the production efficiency, reduce the production cost and save a large amount of energy.

Problems solved by technology

The material movement route in the horizontal structure atmosphere furnace is in the horizontal direction, and the vertical structure is in the vertical direction. Such a single movement route causes the overall length of the atmosphere furnace to be too long or the height is too high, and the space utilization rate of the equipment is low, and it is difficult to operate. Inconvenience to personnel, such as patent number "200410022988.8" named "well-type tankless pre-vacuum protection atmosphere furnace", patent number "200610008219.1" named "intermittent atmosphere furnace", patent number "200620160238.1" named The main defects of patents such as "lifting vacuum atmosphere furnace" and patent number "200820078861.1" and "automatic heating and quenching vacuum atmosphere furnace" are: the temperature needs to be raised and lowered repeatedly during the production process, and continuous production is not possible; the heating method is resistance heating, The heating time is long and the heating efficiency is low; the product is cooled with the furnace, the cooling time is long and the production cycle is long
