For achieving the above object, technical scheme provided by the utility model is: a kind of continuous vacuum stove, it includes material feeding box, charging slide valve, charging cooling section, single-unit furnace, discharging cooling section, discharging sealing damper, feed box, wherein, be arranged on ground rail by charging carriage bottom material feeding box, material feeding box one end is connected with charging cooling section, and its connecting portion is provided with feeding seal flashboard, and the material feeding box the other end is provided with charging oil cylinder; Single-unit furnace is many groups, is assemblied on ground rail bottom it by corresponding furnace body support successively activity, and the single-unit furnace end being positioned at material feeding box one end is provided with charging end cap, and feed end covers the opening for feed being provided with and matching with charging cooling section; Ground rail discharge end is provided with feed box, and feed box is connected with discharging cooling section, and its connecting portion is provided with discharging sealing damper, and the single-unit furnace end being positioned at discharge end is provided with the discharge port matched with discharging cooling section; Be provided with the carbon tube along the distribution of vacuum oven length direction in single-unit furnace, carbon tube matches with charging oil cylinder and to push material.
Described single-unit furnace is made up of five bodies of heater, is flexibly connected between adjacent body of heater, and wherein, middle three is process furnace, feed end be preheating oven, preheating oven end is provided with opening for feed, discharge end be cool furnace, cool furnace end is provided with discharge port.
Described carbon tube, charging oil cylinder are four, the corresponding carbon tube of every bar charging oil cylinder feed oil cylinder.
Described material feeding box, feed box side are provided with corresponding bin gate.
The utility model, after employing such scheme, compares with monomer vacuum oven and continuous vacuum stove:
Single-unit furnace: throughput: 350kg/ days, energy consumption: 1000kwh(50kw × 20h), unit consumption of energy is: 2857kwh/ ton.
Continuous vacuum stove: throughput: 2587kg/ days, energy consumption: 3600kwh(150kw × 24h), unit consumption of energy is: 1392kwh/ ton.Average saving per ton 1465 degree of electricity, calculate with Production Equipment of 2000 t Capacity Per chromium metal, the annual saving electricity charge more than 200 ten thousand yuan.
As can be seen from the above data, adopt continuous vacuum stove than single-unit furnace production efficiency, energy-conservation in have very large advantage.
