Abstract
The utility model relates to a shaft furnace for heat treatment. The shaft furnace comprises a furnace body (1) and a furnace cover (2) at the top of the furnace body (1), wherein a fan (3) is arranged on the furnace cover (2). Compared with the prior art, the shaft furnace for heat treatment has the advantages that the fan is arranged on the furnace cover, so that during heating, hot air at the internal upper part of the furnace body can be blown to the internal lower part of the furnace body under the action of the fan, the hot air flows upwards and downwards in the furnace body, the whole temperature in the furnace body is more uniform, numerical values measured by a thermocouple are more accurate, blanks of different locations have the same temperature, the blank treatment effect is closer to an ideal value, the product yield is higher, and the preparation cost is reduced.
Description
Technical field
The utility model belongs to the firing equipment field, particularly relates to a kind of well formula heat-treatment furnace.
Background technology
At present, the well formula heat-treatment furnace of prior art in use, in when heating since the proportion less of hot-air easily in body of heater above gather, and then cause heat also easily in body of heater above gather, and the middle part of thermocouple operated by rotary motion in body of heater, control device then is as the criterion with the numerical value that thermocouple records, cause the non-uniform temperature in the body of heater, so that the blank in the body of heater is under the different temperature, finally cause yield rate lower, preparation cost is higher.
The utility model content
The utility model provides a kind of body of heater internal temperature more even for above problem, and then so that the well formula heat-treatment furnace that yield rate is higher and preparation cost is lower.
The utility model overcomes the above problems used technical scheme: a kind of well formula heat-treatment furnace with following structure is provided, and it comprises the bell at body of heater and body of heater top, and described bell is provided with fan.
After adopting above structure, compared with prior art, the utility model is owing to be provided with fan at bell, then when heating, under the effect of fan, fan can blow the hot-air of body of heater internal upper part to the bottom in the body of heater, so that hot-air in body of heater on current downflow, and then so that the interior whole temperature of body of heater is more even, the numerical value that thermocouple records is more accurate, and each locational blank is under the identical temperature, and the treatment effect of blank is more near ideal value, final so that the yield rate of product is higher, be prepared into reduction.Therefore it is more even to the utlity model has the body of heater internal temperature, and then so that the characteristics that yield rate is higher and preparation cost is lower.
As improvement, described fan comprises fan blade and motor, described fan blade is positioned at the lower surface of bell, described motor is fixed on the upper surface of bell, and the output shaft of motor is crossed bell and is fixedly connected with fan blade, and then the fan structure of this structure is simple, and preparation cost is lower, and also be conducive to the maintenance in later stage, and reduce maintenance cost; Simultaneously motor from body of heater away from, be not subject to the impact of the heat that body of heater gives out the temperature so that the temperature during machine operation can not overstep the extreme limit guarantees service life and the stability in use of motor.
Description of drawings
Fig. 1 is the structural representation of the utility model well formula heat-treatment furnace.
As shown in the figure: 1, body of heater, 2, bell, 3, fan, 3.1, fan blade, 3.2, motor.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of well formula heat-treatment furnace as shown in Figure 1, it comprises that the bell 2(at body of heater 1 and body of heater 1 top also comprises other parts certainly, but owing to do not relate to the inventive point of the invention, so do not repeat them here), described bell 2 is provided with fan 3.
Described fan 3 comprises fan blade 3.1 and motor 3.2, described fan blade 3.1 is positioned at the lower surface of bell 2, described motor 3.2 is fixed on the upper surface of bell 2, the upper surface of general bell 2 is provided with support, and the shell of motor 3.2 is fixed on the support, the upper surface of the vertical and bell 2 of the output shaft of motor 3.2, and the output shaft of motor 3.2 is crossed bell 2 and is fixedly connected with fan blade 3.1, the center of general bell 2 is provided with central through hole, the output shaft of motor 3.2 is fixedly connected with fan blade 3.1 after passing central through hole on the bell 2, and is provided with sealing ring between the hole wall of central through hole on the output shaft of motor 3.2 and the bell 2.
Above embodiment only is preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly changes in the utility model rights to independence claimed range, all belongs to the utility model protection domain.
