Abstract
The utility model discloses a kind of burner hearth with preheating and refrigerating function of heat treatment equipment, to solve the problems, such as that current burner hearth bulk temperature is uncontrollable.It is made of cylindrical shape burner hearth, cooling-water machine, water heater and pipeline of the outer layer with cyclic water jacket, import, the outlet of cooling-water machine and water heater are connected by pipeline with the cyclic water jacket of burner hearth outer layer respectively, cooling water circulation loop and heated water re-circulation circuit are formed, realizes the cooling and preheating to burner hearth.The utility model preheats burner hearth by the circulating hot water of water heater when high dew point protective atmosphere is tested, and fire box temperature is more than gas dewpoint, ensures that gas does not condense；In high insulation experiment for a long time, burner hearth is cooled down by the circulating water of cooling-water machine, reduces burner hearth damage.
Description
Technical field
It the utility model is related to a kind of burner hearth with preheating and refrigerating function of heat treatment equipment.
Background technology
Thin plate heat-treatment furnace is the common Equipment for Heating Processing in laboratory, and directly heating mode using resistance heats sample,
One or more dry-mixed, wet mixing protective gas can be passed through at the same time injects directly on around sample the various heat for coming simulated production scene
Processing experiment.But it is constrained to sample resistance and directly heats mode, burner hearth bulk temperature is uncontrollable, presently, there are two problems,
Firstth, when high dew point protective atmosphere is tested, the high dew point gas sprayed into runs into cold burner hearth directly condensation into water, reduces gas
Body dew point value, causes test technology to be not allowed, and influences test effect；Secondth, solution heat treatment is when experiment, due to prolonged high
Warm radiation, causes fire box temperature excessive, causes hearth sealability to decline and deforms equivalent damage with burner hearth, reduces burner hearth and uses the longevity
Life.To solve the above problems, a kind of Novel hearth for being capable of adjustment control furnace temperature of design is very important.
Utility model content
The purpose of the utility model is to overcome prior art defect, there is provided a kind of stove with preheating and refrigerating function
Thorax.
What the technical solution of the utility model was realized in：A kind of burner hearth with preheating and refrigerating function, by outer layer
Cylindrical shape burner hearth, cooling-water machine, water heater and pipeline composition with cyclic water jacket, the import of cooling-water machine and water heater, go out
Mouth is connected by pipeline with the cyclic water jacket of burner hearth outer layer respectively, forms cooling water circulation loop and heated water re-circulation circuit,
Realize the cooling and preheating to burner hearth.
Preferably, the cyclic water jacket water inlet pipe phase that the outlet pipe of cooling-water machine and water heater passes through triple valve and burner hearth outer layer
Even, the return pipe of cooling-water machine and water heater is connected by triple valve with the cyclic water jacket return pipe of burner hearth outer layer.
The utility model carries out burner hearth by the circulating hot water of water heater pre- when high dew point protective atmosphere is tested
Heat, fire box temperature are more than gas dewpoint, ensure that gas does not condense；In high insulation experiment for a long time, pass through cooling-water machine
Circulating water cools down burner hearth, reduces burner hearth damage.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure, 1- air-cooled water cooling machines；2- tee ball valves；3- industrial water heaters；4- cyclic water jackets；5- cyclic water jackets into
Water pipe；6- burner hearths；The air-cooled water dispenser outlet pipes of 7-；8- industrial water heaters outlet pipes；9- industrial water heaters return pipes；10-
Air-cooled water dispenser return pipe；11- cyclic water jacket return pipes.
Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of burner hearth with preheating and refrigerating function, by cylindrical furnace of the outer layer with cyclic water jacket 4
Thorax 6, air-cooled water cooling machine 1, industrial water heaters 3 and pipeline composition, air-cooled water dispenser outlet pipe 7 and industrial water heaters water outlet
Pipe 8 is connected by tee ball valve 2 with the cyclic water jacket water inlet pipe 5 of 6 outer layer of burner hearth, and air-cooled water dispenser return pipe 10 and industry water add
Hot device return pipe 9 is connected by tee ball valve 2 with the cyclic water jacket return pipe 11 of 6 outer layer of burner hearth, passes through falling for tee ball valve 2
Change, cooling water circulation loop and heated water re-circulation circuit can be formed respectively, realize cooling and preheating to burner hearth 6.
Wherein air-cooled water cooling machine 1 and industrial water heaters 3 are common type on the market, it is desirable to air-cooled water cooling machine
1 temperature control is at 3 DEG C~30 DEG C, and 3 water temperature of industrial water heaters controls 50-100 DEG C, and tee ball valve 2 is manual L-type three-way ball
Valve, is mainly used for the switching of hot and cold water circulation, water pipe is stainless steel, it is desirable to is resistant to rapid heat cycle.
During high dew point protective atmosphere experiment, tee ball valve 2 is switched to hot water circuit, and the setting of 3 temperature of industrial water heaters is big
In dew-point temperature；For a long time during high insulation experiment, tee ball valve 2 is switched to circulating chilled water, and water temperature is according to specific test temperature
Setting, two tee ball valves 2 require simultaneously operating.
The utility model when high dew point protective atmosphere is tested, by the circulating hot waters of industrial water heaters 3 to burner hearth 6 into
Row preheating, 6 temperature of burner hearth are more than gas dewpoint, ensure that gas does not condense；In high insulation experiment for a long time, by air-cooled
The circulating water of formula cooling-water machine 1 cools down burner hearth 6, reduces burner hearth 6 and damages.
