Description
Technical field
The utility model relates to a kind of vacuum air-quenching electric tube furnace, specifically, relates to a kind of vacuum air-quenching electric tube furnace with hot baffle.
Background technology
The energy consumption of vacuum air-quenching electric tube furnace is very high, in order to economize energy, is generally all provided with reasonable insulation construction.In addition, the boiler tube two ends of vacuum air-quenching electric tube furnace need to place hot baffle.Hot baffle can stop heat in boiler tube to external radiation, plays insulation and energy-conservation effect, is conducive to again the homogeneous temperature made in boiler tube.
Fig. 1 illustrates the hot baffle of vacuum air-quenching electric tube furnace in the past, and wherein Reference numeral 1 represents baffle plate, and Reference numeral 2 represents set bolt, and Reference numeral 3 represents bolt hole, and Reference numeral 4 represents through hole.As shown in Figure 1, at least two overlapped baffle plates 1 are connected by set bolt 2, are provided with gap between adjacent screen 1.Each baffle plate 1 is provided with the through hole 4 of some.Hot baffle is put in the both sides of main thermal field, for preventing heat in boiler tube to external radiation.The effect of the through hole 4 on baffle plate 1 is heat radiation and ventilations when cooling.
But above-mentioned hot baffle exists an awkward problem, that is, the object in order to dispel the heat and ventilate when reaching cooling, always wishes that the quantity of through hole 4 is many as far as possible, and better keeps off thermal effect to play, but wish that the quantity of through hole 4 is the least possible.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of vacuum air-quenching electric tube furnace, and heat in boiler tube can be prevented well to external radiation, again can the heat radiation and ventilating when cooling.
To achieve these goals, the utility model provides a kind of vacuum air-quenching electric tube furnace, comprising: boiler tube (1), extends in a first direction; Sleeve (2), extends in said first direction, is positioned at the inner side of described boiler tube; And baffle plate (4), be positioned at described sleeve, and be arranged on described sleeve, described baffle plate is tabular, and described baffle plate can rotate in described sleeve, makes the space of the described baffle plate both sides of described sleeve be communicated with or disconnect.
Vacuum air-quenching electric tube furnace of the present utility model, described boiler tube cylindrically.
Vacuum air-quenching electric tube furnace of the present utility model, described sleeve cylindrically.
Vacuum air-quenching electric tube furnace of the present utility model, described baffle plate is discoideus.

Accompanying drawing explanation
Fig. 1 illustrates the hot baffle of vacuum air-quenching electric tube furnace in the past.
Fig. 2 is left view according to the vacuum air-quenching electric tube furnace of the utility model embodiment and front view.
Detailed description of the invention
Below in conjunction with accompanying drawing, vacuum air-quenching electric tube furnace of the present utility model is described in detail.
Fig. 2 is left view according to the vacuum air-quenching electric tube furnace of the utility model embodiment and front view.As shown in Figure 2, vacuum air-quenching electric tube furnace mainly comprises: boiler tube 1; Sleeve 2; Flapper axle 3; And baffle plate 4.
Boiler tube 1 cylindrically, extends in the horizontal direction.
Sleeve 2 also cylindrically, extends in the horizontal direction, is positioned at the radially inner side of boiler tube 1.The external diameter of sleeve 2 is slightly less than the internal diameter of boiler tube 1.
Baffle plate 4 is in discoideus, and its diameter is slightly less than the internal diameter of sleeve 2.In the position that the center of baffle plate 4 is top a little, with the straight line of the vertical direction in the center of circle by baffle plate 4 for symmetry axis symmetrically has two flapper axles 3.Flapper axle 3 in cylindric, from the outer peripheral face of baffle plate 4 in the horizontal direction outwardly.
At the inwall of sleeve 2, in the position that two flapper axles 3 with baffle plate 4 are corresponding, have from the horizontally outward recessed recess of the inwall of sleeve 2.Flapper axle 3 is supported on recess, makes baffle plate 4 can with the straight line connecting two flapper axles 3 for pivot center rotates at sleeve 2 internal freedom.
As shown in Figure 2, baffle plate 4 is at least positioned at the two ends of sleeve 2, can also be positioned at the mid portion of sleeve 2.
When vacuum air-quenching electric tube furnace be in vacuumize heating or argon filling heated condition time, baffle plate 4 is in vertical state because of gravity, and this state can prevent heat in boiler tube to external radiation.After heating terminates, when blower fan drives the gas high-speed circulating in boiler tube, baffle plate 4 rotates 90 degree due to the effect of gas, thus ensures farthest to ventilate and heat radiation.
Vacuum air-quenching electric tube furnace of the present utility model, because without the need to perforate on baffle plate, thus can guarantee that gear thermal effect reaches best.Meanwhile, because when vacuum air-quenching electric tube furnace cools rotatable 90 degree, thus substantially increase ventilation and radiating efficiency.
Test proves, when vacuum air-quenching electric tube furnace of the present utility model is in heated condition, the temperature at boiler tube two ends is obviously much lower, and this illustrates that gear thermal effect is obvious.Specifically, rear three thermocouples in before vacuum air-quenching electric tube furnace of the present utility model has, two ends temperature and medium temperature are very close, and only difference is less than 3 degree.And when using hot baffle in the past, two ends temperature differs more than 10 degree with medium temperature, this illustrates that hot baffle of the present utility model makes the temperature in boiler tube more even.
In addition, when vacuum air-quenching electric tube furnace of the present utility model is in the state of cooling, wind speed is faster, and cooling is faster, and cool time shortens more than 50%.
