Abstract
The utility model relates to a box calcining furnace with double chamber which belongs to non-continuous flame heating furnace used to solve the existing single chamber heating furnace's defects of high energy consumption, low efficiency, incomplete burning of articles, etc. The utility model uses the double chambers instead of the traditional single chamber heating furnace, and the two chambers are communicated by a gas passage arranged at the bottom of the furnace. The gas passage is arranged under the bottom of the furnace which is composed of the fire-resistant material and leaves a gap, and the chamber is communicated with the gas passage by the gap at the bottom of the furnace. The fume outlets of the two chambers are communicated with the chimney by the valves. The double chambers are heated by the flame alternatively, and the corresponding another chamber carries out preheating by the flame smoke and the waste heat after the new articles are filled in. So the utility model can reduce the energy consumption, improve the efficiency and improve the heating quality of the articles.
Description
Technical field
The utility model relates to a kind of flame heat box type heater, belongs to the discontinuous flame heating furnace.Be mainly used in the shell roasting of model casting industry, also can be used for the solid material heating of other industry.
Background technology
So far, flue gas and waste heat that known flame heat box type heater flame produces are directly discharged from flue, even adopt the preheater recovery waste heat also can only energy-conservation 10～30%, a large amount of heat energy are taken away by flue gas, thereby the energy consumption high efficiency is low, limited by heat time heating time, heating object is easy to generate non-burn-through phenomenon, influences heating quality.
Summary of the invention
Existing flame heat box type heater energy consumption high efficiency is low in order to overcome, the deficiency of heating quality difference, the utility model provides a kind of double chamber box type heater, this heating furnace can make full use of fire smoke gases and waste heat directly carries out preheating to heating object, improve the utilization rate of heat energy, thereby reduced the energy consumption of heating furnace; Since be heated material by directly with flame heat preheating in the past, not only the efficiency of heating surface is improved, the temperature homogeneity that heating quality particularly is heated material is also improved thereupon.
The method that the utility model solves the existing problem of prior art is: heating furnace has adopted double chamber's scheme.Double chamber's box type heater is made of two furnace chambers, and two furnace chambers are communicated with by the exhaust gases passes that is arranged on the furnace chamber bottom, and two furnace chambers are equipped with independently flame-thrower nozzle and exhanst gas outlet separately, and the exhanst gas outlet of two furnace chambers is communicated with chimney by three-way diverter valve.
The course of work of the present utility model is such: beginning, in two furnace chambers, all place and add thermal material, allow the triple valve that is communicated with two furnace chamber exhanst gas outlets and chimney close the exhanst gas outlet of left furnace chamber, at this moment, the exhanst gas outlet and the chimney of right furnace chamber are communicated with, light the thermal-flame that adds of left furnace chamber, directly the thermal material that adds to left furnace chamber carries out flame heat; At this moment, the flue gas and the waste heat that add the thermal-flame generation of left furnace chamber enter right furnace chamber by the exhaust gases passes that is communicated with two furnace chambers, and the thermal material that adds that is placed on right furnace chamber is carried out preheating, and this process finished after the thermal material heating is finished until adding of left furnace chamber.Take out the new material of packing into behind the material that left furnace chamber heated at once, the counter-rotating three-way diverter valve, close the exhanst gas outlet of right furnace chamber, light the thermal-flame that adds of the right furnace chamber, the thermal material that adds of right furnace chamber back warp being crossed preheating directly heats, right furnace chamber added flue gas and the waste heat that thermal-flame produces and entered left furnace chamber by exhaust gases passes this moment, and the material of the left furnace chamber of newly packing into is carried out preheating.The heating work of double chamber's box type heater is finished in a left side furnace chamber and right furnace chamber hocket heating, preheating.
Advantage of the present utility model be to utilize waste heat directly to the heating object preheating, heat energy utilization rate height, thereby reach and cut down the consumption of energy is raised the efficiency the purpose with heating quality.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Accompanying drawing 1 is the organigram of the box roaster of double chamber.
In the accompanying drawing 1,1, flame-thrower nozzle, 2, left furnace chamber, 3, exhanst gas outlet, 4, exhaust gases passes, 5, exhanst gas outlet, 6, reversal valve, 7, right furnace chamber, 8, flame-thrower nozzle, 9, furnace bottom, 10, chimney, 11, furnace bottom.
The specific embodiment
As shown in Figure 1, the box roaster of double chamber is made of left furnace chamber 2 and 7 two furnace chambers of right furnace chamber; Left side furnace chamber 2 is furnished with flame-thrower nozzle 1 and exhanst gas outlet 3, and right furnace chamber 7 is furnished with flame-thrower nozzle 8 and exhanst gas outlet 5; Left side furnace chamber 2 and right furnace chamber 7 are communicated with by exhaust gases passes 4, and left furnace chamber exhanst gas outlet 3 and right furnace chamber exhanst gas outlet 5 are communicated with chimney 10 by reversal valve 6.In accompanying drawing 1 illustrated embodiment, the exhaust gases passes 4 that is communicated with left furnace chamber 2 and right furnace chamber 5 is arranged on the furnace chamber bottom, the furnace bottom 9 and the furnace bottom 11 that are made of refractory material leave the slit, flue gas that flame produces and waste heat enter the passage 4 that is communicated with two furnace chambers by the furnace bottom slit, enter another furnace chamber through passage 4 again and carry out preheating to adding thermal material.Flue gas and waste heat that the slit of furnace bottom part can make heated oven chamber's flame produce enter exhaust gases passes equably from whole furnace bottom part, thereby make and add thermal material and be heated evenly, equally, the slit of furnace bottom part can make the flue gas and the waste heat that enter the exhaust gases passes from heated oven chamber enter the preheating furnace chamber equably, makes the even preheating of pre-thermal material.
