Description
Technical field
This utility model relates to a kind of powder metallurgy sintering furnace, specifically a kind of net belt type sintering furnace.
Background technology
Metallic sintered products needs to can be only achieved through high temperature sintering the performance requirement of use after compressing, existing Powder Metallurgy Plant is used mostly net belt type sintering furnace and processes, the efficiency ensureing production with this and yield, such as Fig. 3, the cooling section of net belt type sintering furnace carries out heat exchange by circulating water furnace wall, make temperature and product cooling in burner hearth, but, when the product loaded in burner hearth is too much, the heat of product accumulation is too much, and furnace wall is thicker, furnace wall is few with contact area in stove, cause cooled slowly, in this case, the product hardness produced reduces, metallographic is abnormal, poor product quality.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of net belt type sintering furnace, sets up cooling tube and heat radiation scale in thorax, and good heat dissipation effect, rate of cooling is fast, produces product hardness and metallographic is up to standard, good product quality.
This utility model solves the technical scheme that its technical problem is used:
A kind of net belt type sintering furnace, including furnace wall, burner hearth in furnace wall, the wall cooling tube arranged between furnace wall and burner hearth, described wall cooling tube is provided with the first water inlet and the first outlet, being provided with cooling tube in thorax in its described burner hearth, in described thorax, cooling tube is cased with the scale that dispels the heat, and in described thorax, cooling tube is provided with the second water inlet and the second outlet.
Further, the first described water inlet is arranged on the lower end of side, furnace wall, and the first described outlet is arranged on the upper end of furnace wall opposite side.
Further, the second described water inlet and the second outlet are arranged on the top of furnace wall.
Further, in described thorax, cooling tube is arranged on roof of the furnace.
Further, described heat radiation scale is rectangular.
Further, described heat radiation scale is inserted in cooling tube in thorax by welding.
The beneficial effects of the utility model are: cooling water is by wall cooling tube, from the first water inlet to the first outlet, heat exchange is carried out with furnace wall, so that temperature and product cooling in burner hearth, on the other hand, cooling water puts cooling tube in thorax by setting up in burner hearth, in thorax, cooling tube is cased with the scale that dispels the heat, cooling water is by cooling tube in thorax, from the second water inlet to the second outlet, heat exchange is directly carried out with burner hearth, so that temperature and product cooling in burner hearth, simultaneously, the setting of heat radiation scale too increases the contact area of cooling water and burner hearth, the decline of temperature in quickening burner hearth, good heat dissipation effect, guarantee under high useful load, product cooling accelerates, ensure the hardness of product, metallographic is normal, good product quality.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is A-A face of the present utility model profile,
Fig. 3 is the structural representation of net belt type sintering furnace of the prior art.
Detailed description of the invention
With reference to Fig. 1 ~ 2, a kind of net belt type sintering furnace, including furnace wall 1, burner hearth 2 in furnace wall 1, the wall cooling tube 3 arranged between furnace wall 1 and burner hearth 2, wall cooling tube 3 is provided with the first water inlet 31 and the first outlet 32, is provided with cooling tube 4 in thorax in burner hearth 2, in thorax, cooling tube 4 is cased with the scale 5 that dispels the heat, and in thorax, cooling tube 4 is provided with the second water inlet 41 and the second outlet 42.
Cooling water is by wall cooling tube 3, from first water inlet the 31 to the first outlet 32, heat exchange is carried out with furnace wall 1, so that temperature and product cooling in burner hearth 2, on the other hand, cooling water puts cooling tube 4 in thorax by setting up in burner hearth 2, in thorax, cooling tube 4 is cased with the scale 5 that dispels the heat, cooling water is by cooling tube 4 in thorax, from second water inlet the 41 to the second outlet 42, heat exchange is directly carried out with burner hearth 2, so that temperature and product cooling in burner hearth 2, simultaneously, the setting of heat radiation scale 5 too increases the contact area of cooling water and burner hearth 2, the decline of temperature in quickening burner hearth 2, good heat dissipation effect, guarantee under high useful load, product cooling accelerates, ensure the hardness of product, metallographic is normal, good product quality.
In the present embodiment, it is preferred that the first water inlet 31 is arranged on the lower end of side, furnace wall 1, the first outlet 32 is arranged on the upper end of furnace wall 1 opposite side, and the first water inlet 31 is arranged on lower end, is possible to prevent to cool down water insufficient entrance wall cooling tube 3, it is ensured that cooling effect.
In the present embodiment, it is preferred that the second water inlet 41 and the second outlet 42 are arranged on the top of furnace wall 1, and in thorax, cooling tube 4 is arranged on burner hearth 2 top, it is simple to install while manufacturing, deposit for product and leave adequate space.
In the present embodiment, it is preferred that heat radiation scale 5 is rectangular, strengthen film-cooled heat.
In the present embodiment, it is preferred that heat radiation scale 5 is inserted in cooling tube 4 in thorax by welding, simple in construction is easily manufactured.
The above, better embodiment the most of the present utility model, but this utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
