Description
Technical field
The utility model is related to nitriding furnace, especially cooling system.
Background technology
Nitriding furnace is the equipment that Nitrizing Treatment is carried out to workpiece, and the principle of nitriding is：Workpiece is put into nitriding furnace, is first arranged
Go out the air of nitriding furnace, ammonia is then passed through into nitriding furnace, heat, then cool down.
Current nitridation furnace structure is a lot, and one kind is disclosed in the .6 of Application No. 201620260294 patent document
Nitriding furnace, including furnace shell, flue and bell, the furnace shell are the cylinder of upper opening, and flue is in furnace shell, and bell is located at stove
At the opening of shell, elevating mechanism is connected with bell, insulating, the inner side of insulating are provided between furnace shell and flue
Provided with heating element heater, bell is provided with motor and thermocouple, the lower end of motor be provided with blade, the flue provided with material frame frame,
Guiding subassembly for the inlet duct for being passed through nitriding gas from flue bottom and for carrying out drainage to nitriding gas.Should
It is high that nitriding furnace good airproof performance, product nitrogenize the product quality after uniform, nitrogen treatment.But, the cooling performance of nitriding furnace needs
Improve.
The content of the invention
In order to make cooling uniform, the utility model provides a kind of nitriding furnace cooling system.
To reach there is cavity, flue in above-mentioned purpose, a kind of nitriding furnace cooling system, including furnace shell and flue, furnace shell
It is located in cavity, is cased with the forced air cooled tube of more than two from top to bottom on the outer wall of flue, each forced air cooled tube is provided with air inlet
And air outlet, it is provided with furnace shell on air blower, air blower and is connected with blast pipe, is connected between air inlet and blast pipe
Air-out branch pipe, air-out branch pipe connection discharge pipe are connected with winding pipe, air outlet；Discharge pipe connects exhaust duct.
Above-mentioned nitriding furnace cooling system is to the cooling procedure of workpiece：Air blower cold wind is blown into respectively through blast pipe into
In wind branch pipe, cold wind enters forced air cooled tube through each winding pipe, and the heat entered in cold wind and flue in forced air cooled tube enters
Row heat exchange, the air of heat exchange is discharged through air-out branch pipe and discharge pipe, and this mode, extraneous air has respectively entered air-cooled
Manage, being swapped with the heat in flue for the air independence in forced air cooled tube is entered relative to existing cold wind through air blower
The mode of discharge after in furnace shell, heat exchange of the present utility model is more abundant, uniform, good cooling results.
Further, there is gap, air blower is communicated with gap, and gap is communicated with exhaust duct between furnace shell and flue.Should
The type of cooling combines the above-mentioned type of cooling, realizes dual-cooled so that cool down more abundant, the efficiency high of cooling.
Further, there is gap between adjacent forced air cooled tube, the structure, the heat transfer between adjacent airduct is few, phase
Influence between mutually is small, realizes that each forced air cooled tube is individually cooled down.
Further, annular groove is provided with the outer wall of flue, forced air cooled tube holding is in annular groove.So, forced air cooled tube with
The contact area of flue is big, and the heat of transmission is more, and the effect of cooling is more preferable.And forced air cooled tube can also be determined by annular groove
Position.
Further, the section of forced air cooled tube is semicircle, and the string side of forced air cooled tube is contacted with flue.Plane contact is realized, is increased
The area of big heat transfer, cooling effect might as well.
Brief description of the drawings
Fig. 1 is the stereogram of nitriding furnace cooling system.
Fig. 2 is the side schematic view of nitriding furnace cooling system.
Fig. 3 is the sectional view of furnace shell and flue.
Fig. 4 is the sectional view of forced air cooled tube.
Embodiment
The utility model is further elaborated with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, Fig. 2 and Fig. 3, nitriding furnace cooling system includes furnace shell 1 and flue 2.
There is cavity 11 in furnace shell 1.There is workpiece chamber 21 in flue 2.
It is cased with having gap between the forced air cooled tube 5 of more than two, adjacent forced air cooled tube from top to bottom on the outer wall of flue 2,
So, in cooling procedure, the possibility that heat exchange occurs for adjacent forced air cooled tube is small, of course, it is possible to be set on the outer wall of flue
Annular groove, forced air cooled tube holding is in annular groove, so, and the contact area of forced air cooled tube and flue is big, and the heat of transmission is more, cooling
Effect is more preferable.In addition, being semicircle referring to the section of Fig. 4 or forced air cooled tube, the string side 58 of forced air cooled tube is allowed to be connect with flue
Touch, realize plane contact, increase the area of heat transfer, cooling effect might as well.Each forced air cooled tube 5 is provided with air inlet and air-out
Mouthful, it is provided with furnace shell 1 on air blower 50, air blower 50 and is connected with three-way pipe 500, the port of export connection of three-way pipe 500
Blast pipe 51, is connected with winding pipe 52, air outlet between air inlet and blast pipe 51 and is connected with air-out branch pipe 53, air-out
Branch pipe 53 connects discharge pipe 54.There is gap 100, another port of export and the phase of gap 100 of three-way pipe between furnace shell 1 and flue 2
It is logical, provided with the exhaust duct 55 communicated with gap 100 and discharge pipe on furnace shell 1.
Above-mentioned nitriding furnace cooling system is to the cooling procedure of workpiece：Air blower cold wind is blown into respectively through blast pipe into
In wind branch pipe, cold wind enters forced air cooled tube through each winding pipe, and the heat entered in cold wind and flue in forced air cooled tube enters
Row heat exchange, the air of heat exchange is discharged through air-out branch pipe and discharge pipe, and this mode, extraneous air has respectively entered air-cooled
Manage, being swapped with the heat in flue for the air independence in forced air cooled tube is entered relative to existing cold wind through air blower
The mode of discharge after in furnace shell, heat exchange of the present utility model is more abundant, uniform, good cooling results.After cold wind is by gap
Workpiece is cooled down, along with the cooling of forced air cooled tube, dual-cooled, good cooling results is realized.
