Abstract
The utility model relates to a preevacuated special atmosphere furnace which comprises a furnace body, furnace linings, a support, heating wires and a furnace cover, wherein a furnace cavity is arranged in the middle of the furnace body; the furnace linings are arranged inside the furnace and abut against the inner wall of the furnace body; one end of the support is fixed on the furnace linings and the other end of the support extends into the furnace cavity; the heating wires are arranged on the support; the furnace cover covers on the top of the furnace body; and the furnace cover is further provided with a group of a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe extend into the furnace cavity. When heat preservation is over, the temperature can be quickly reduced by only filling cold water without oxidizing the workpieces, thereby improving the manufacturing efficiency of the preevacuated special atmosphere furnace.
Description
[technical field]
The utility model relates to a kind of Equipment for Heating Processing, is specially a kind of forvacuum special atmosphere oven.
[background technology]
At present, the enterprise that the application special atmosphere oven is heat-treated workpiece (for example gear) is more and more, and the workpiece quality that it produces is better, extensively is applied to every field such as automobile making, engineering equipment and military project.
And existing forvacuum special atmosphere oven purposes is single, and structure design is unreasonable, and heat-insulating property is poor, can't satisfy the production of precision optical machinery spare part; It is slow to move back warm speed in the stove of these special atmosphere ovens, has had a strong impact on the production efficiency of this stove.
Therefore, for avoiding the problems referred to above, necessaryly provide a kind of structure improved forvacuum special atmosphere oven that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of rational in infrastructure, forvacuum special atmosphere oven that cooling rate is fast.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of forvacuum special atmosphere oven, and it comprises body of heater, furnace lining, support, nichrome wire and bell, wherein, described body of heater central authorities are provided with a furnace chamber; Described furnace lining is positioned at body of heater and is connected on the inwall of body of heater; Described support one end is mounted on the furnace lining, and the other end extends in the furnace chamber; Described nichrome wire is arranged on the support; Described bell is placed on the top of body of heater, further is provided with one group of water inlet pipe and rising pipe that extends in the furnace chamber on this bell.
Forvacuum special atmosphere oven of the present utility model further is set to: the top of described bell is provided with tensimeter, vent valve and safety valve.
Forvacuum special atmosphere oven of the present utility model further is set to: also be provided with a vacuum extractor and a diffuser on the described bell, described vacuum extractor, diffuser are communicated with furnace chamber respectively.
Forvacuum special atmosphere oven of the present utility model also can be set to: described nichrome wire is positioned at furnace chamber.
Compared with prior art; the utlity model has following beneficial effect: forvacuum special atmosphere oven of the present utility model is by being provided with one group of water inlet pipe and rising pipe that extends in the furnace chamber on bell; only need feeding cold water to realize fast cooling and make the workpiece can be not oxidized when insulation finishes the back, the production efficiency of this stove is provided.
[description of drawings]
Fig. 1 be forvacuum special atmosphere oven of the present utility model partly cut open synoptic diagram.
Fig. 2 is the synoptic diagram of the bell of forvacuum special atmosphere oven of the present utility model.
[embodiment]
See also shown in Figure of description 1 and the accompanying drawing 2, the utility model is a kind of forvacuum special atmosphere oven, and it is made up of members such as body of heater 1, furnace lining 2, support 3, nichrome wire 4 and bells 5.
Wherein, described body of heater 1 is vertical setting, and its central authorities are provided with a furnace chamber 11, but in this furnace chamber 11 place work piece (not shown).Described furnace lining 2 is positioned at body of heater 1 and is connected on the inwall of body of heater 1.Described support 3 is arranged from the bearing of trend of body of heater 1, and an end of each support 3 is mounted on the furnace lining 2, and the other end extends in the furnace chamber 11.Described nichrome wire 4 is used for heated parts, and it is to be arranged on the support 3 and be positioned at furnace chamber 11.
Described bell 5 is placed on the top of body of heater 1, which is provided with one group of water inlet pipe 51 and rising pipe 52 that extends in the furnace chamber 11, thereby reduces temperature in the furnace chamber 11 fast by feeding round-robin cold water water inlet pipe 51 and rising pipe 52 in.The top of described bell 5 also is provided with tensimeter 53, vent valve 54 and safety valve 55, and described tensimeter 53 is used to detect the pressure in the furnace chamber 11, and vent valve 54 and safety valve 55 are used for guaranteeing that pressure in the furnace chamber 11 is in safety range.Also be provided be used to find time in the furnace chamber 11 vacuum extractor 56 of gases and the diffuser 57 that furnace chamber 11 internal gas pressures are recovered in a cooling back on the described bell 5, described vacuum extractor 56, diffuser 57 are communicated with furnace chamber 11 respectively.
Forvacuum special atmosphere oven of the present utility model is by being provided with one group of water inlet pipe 51 and rising pipe 52 that extends in the furnace chamber 11 on bell 5; only need feeding cold water to realize fast cooling and make the workpiece can be not oxidized when insulation finishes the back, the production efficiency of this stove is provided.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
