Fig. 2 is the cross-sectional schematic along B direction in Fig. 1.
Detailed description of the invention
Core of the present invention is to provide a kind of combustion furnace, and this combustion furnace can control the temperature of its different section.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See accompanying drawing 1 and accompanying drawing 2, the combustion furnace that the embodiment of the present invention provides mainly comprises boiler tube 1, furnace shell 3, heat preservation component 4, heater block 5 and temperature sensor 7, heat preservation component 4 is filled in the inside of furnace shell 3, furnace shell 3 has the hollow cavity 12 running through heat preservation component 4, also comprise cavity dividing plate 6, hollow cavity 12 is divided into several sections of furnace chambers by cavity dividing plate 6, heater block 5 and temperature sensor 7 are all installed in every section of furnace chamber, and boiler tube 1 is placed in hollow cavity 12 also through furnace shell 3, cavity dividing plate 6 and heater block 5.
The furnace shell 3 that the embodiment of the present invention provides is specially split type furnace shell 3, and namely furnace shell 3 can dimidiation, and it is easier that such structural design can make the parts of furnace shell 3 inside install, and certainly, is also not limited thereto.And the material of furnace shell 3 can be metal, also can for be formed by other materials manufacture.
Heat preservation component 4 is formed by the manufacture of fragility insulation material, certainly, and also can for be formed by the material manufacture of other types.
When section different during needs are to boiler tube 1 heats, control the heater block 5 in every section of furnace chamber respectively, the temperature in every section of furnace chamber is responded to by temperature sensor 7, thus different section furnace chamber can be controlled be stabilized in different temperature respectively, thus meet the object that special experiment instrument has various temperature to require to boiler tube in combustion furnace.
Cavity dividing plate 6 herein can be specially one, also can be set to multiple cavity dividing plate 6.When being set to a cavity dividing plate 6, cavity dividing plate 6 can being arranged on the position, middle of hollow cavity 12, also can being referred to as median septum, namely hollow cavity 12 being separated into two sections.Thus combine by the heater block 5 in every section and temperature sensor 7 temperature controlled in two sections, reach the object making to have two flat-temperature zones in combustion furnace.
Cavity dividing plate 6 is specially the cavity dividing plate 6 be made up of heat-barrier material, specifically can be formed by glass fibre and asbestos etc. manufactures, certainly also be not limited thereto.
As shown in Figure 1, on furnace shell 3, air guide box 9 can also be installed, and be provided with air channel through hole between air guide box 9 and hollow cavity 12.Cool with stove relative to the boiler tube 1 in combustion furnace of the prior art, provide air guide box 9 in embodiments of the present invention, cold wind just can be entered by air guide box 9, and cold wind enters hollow cavity 12 through air channel through hole, hot blast is got rid of from air guide box 9 finally by air channel through hole, thus can realize one section of hollow cavity 12 cooling faster.Certainly, can arrange multiple air guide box 9, cold wind leads to the hollow cavity 12 of different section from multiple air guide box 9 respectively, just can realize several sections of objects of carrying out comparatively fast lowering the temperature to hollow cavity 12.
As shown in Figure 2, can be connected with wind isolation board 8 on air guide box 9, above-mentioned air channel through hole separates for air intake passage and air-out passage by wind isolation board 8, and air intake passage is communicated with the air inlet on air guide box 9, and air-out passage is communicated with the air outlet on air guide box 9.Thus cold wind just can flow to air intake passage from the air inlet air guide box 9, hot blast flows out from air-out passage, enters the air outlet of air guide box 9, is finally passed in air.
In the air inlet of air guide box 9, fan 10 can be installed, fan 10 can be specially one, two or more.As shown in the direction of arrow in Fig. 2, the fan 10 of the air inlet of air guide box 9 brings cold wind into air intake passage, and hot blast flows to the air-out passage of air guide box 9 from air-out passage, and the air outlet that the hot blast of air-out passage enters on air guide box 9 is got rid of.Thus the heat in hollow cavity 12 is taken away fast, greatly reduce the used time that boiler tube 1 cools.
As shown in Fig. 2 direction, air channel through hole can relative to the symmetrical distribution of hollow cavity 12, and wind isolation board 8 genesis analysis is in the centre position of air channel through hole.The setting of such position relationship, can make cold wind enter from the right half part of the hollow cavity 12 Fig. 2, and left-half flows out.Arrange like this and the effect of cooling can be made more obvious.
Can install on furnace shell 3 and be used for heat insulation endplate 2, endplate 2 is distributed in the both ends of hollow cavity.Herein endplate 2 heat is set when heater block 5 can be avoided to heat from the loss of end, thus the constant of boiler tube 1 internal temperature can be kept.
Can have groove on heat preservation component 4, as shown in Figure 1, and cavity dividing plate 6 is the structure be made up of multiple hollow circular cylinder, and cavity dividing plate 6 is stuck in the groove of heat preservation component 4 by an one cylinder.Cavity dividing plate 6 is stuck in the groove of heat preservation component 4, can increase the stability of cavity dividing plate 6 in hollow cavity 12.Cavity dividing plate 6 can specifically be combined by the cylinder of 5 hollows, and middle cylinder external diameter is maximum, the cylinder external diameter of the right and left takes second place, the cylindrical external diameter being distributed in the maximum cylinder both sides of external diameter is minimum, such vibrational power flow can facilitate wire to be wrapped on the minimum hollow circular cylinder of the external diameter of cavity dividing plate 6, and wire not easily drops.
And also the concrete shape of endplate 2 can be set to the shape being same as above-mentioned cavity dividing plate 6, this kind of vibrational power flow can facilitate endplate 2 to be arranged on furnace shell 3, can also facilitate the winding of wire.
Temperature sensor 7 can be set to platinum resistance temperature sensor, as shown in Figure 1, furnace shell 3 and heat preservation component 4 have through hole, and RTD is placed in hollow cavity 12 by its through hole, and RTD can not contact with miscellaneous part.Certain temperature sensor 7 herein also can be set to the temperature sensor 7 of other types.
Heater block 5 can be set to Resistant heating parts, also in hollow cavity 12, support bar 11 can be installed, and the end face of cavity dividing plate 6 has through hole, support bar 11 is plugged in the through hole of cavity dividing plate 6, resistance wire can be wrapped in above-mentioned support bar 11 periphery.And can evenly be provided with 3 support bars 11 in hollow cavity 12, the support bar 11 of other quantity roots can certainly be set to.
Certainly, also the end of endplate 2 can be provided with through hole, above-mentioned support bar 11 is also plugged in the through hole of endplate 2.Support bar 11 can be specially ceramic bar, also can be the not heat conducting bar of other types.
When heater block 5 is resistance wire, resistance wire is wrapped in the periphery of support bar 11, cavity dividing plate 6 and endplate 2 are all wound with wire above, can be heated by wire to resistance wire, and furnace shell 3 has the through hole putting into wire above.
Above combustion furnace provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
