In the flow process of processing neodymium iron boron, often need to use agglomerating plant to its sintering.As shown in Figure 1, existing NbFeB sintered equipment is put into neodymium iron boron that sintering equipment 1 is not open close enters air-flow, neodymium iron boron is carried out to sintering, the waste gas that sintering equipment 1 produces is discharged from exhaust apparatus 2, because the interior temperature of sintering equipment 1 is higher, the EGT entering in exhaust apparatus 2 is still very high, but this part heat is directly discharged from, fail to be utilized well, and then reduced the thermal efficiency of NbFeB sintered equipment.
Utility model content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, spy provides a kind of NbFeB sintered equipment, can make full use of the heat of waste gas, there is the higher thermal efficiency, to overcome the NbFeB sintered equipment of prior art, have the low defect of the thermal efficiency.
Two, technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of NbFeB sintered equipment, comprise sintering equipment, be arranged on the exhaust apparatus of described sintering equipment top, the jacket that the outer cover of described exhaust apparatus has upper and lower two ends all to seal, the inside of described jacket and the outside of described exhaust apparatus form annular heat runner, the upper left side of described jacket is provided with air inlet, and the lower right of described jacket is provided with gas outlet, and described gas outlet is stretched in described sintering equipment.
In above-mentioned NbFeB sintered equipment, the cylindric body that described jacket is integral type.
In above-mentioned NbFeB sintered equipment, described jacket is split type circle-shaped body, and it comprises the first jacket and the second jacket.
In above-mentioned NbFeB sintered equipment, described the first jacket and described the second jacket are from top to bottom successively set on the outside of described exhaust apparatus, and the gas outlet of described the first jacket communicates with the air inlet of described the second jacket.
In above-mentioned NbFeB sintered equipment, on the inwall of described jacket and the outer wall of described exhaust apparatus, intersect and be provided with flow-stopping plate.
In above-mentioned NbFeB sintered equipment, on the outer wall of described jacket, be provided with for heat insulation separation sleeve.
Three, the beneficial effects of the utility model
Compared with prior art, a kind of NbFeB sintered equipment of the present utility model, the outer cover of exhaust apparatus has jacket, form Packed annular heat runner, the air-flow that enters annular heat runner can fully absorb the heat of exhaust apparatus, and enters sintering equipment from gas outlet, takes full advantage of like this waste heat of waste gas in exhaust apparatus, greatly improve the temperature in agglomerating plant, and then improved the thermal efficiency of agglomerating plant.
Accompanying drawing explanation
Fig. 1 is the structural representation of NbFeB sintered equipment in prior art;
Fig. 2 is the structural representation of the NbFeB sintered equipment of the utility model embodiment mono-;
Fig. 3 is the structural representation of the NbFeB sintered equipment of the utility model embodiment bis-;
Wherein, 1 is sintering equipment, and 2 is exhaust apparatus, and 3 is jacket, and 31 is air inlet, and 32 is gas outlet, and 4 is annular heat runner, and 5 is the first jacket, and 6 is the second jacket, and 7 is flow-stopping plate, and 8 is separation sleeve.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
Embodiment mono-:
The structure of the NbFeB sintered equipment of the utility model embodiment mono-as shown in Figure 2, comprises sintering equipment 1 and exhaust apparatus 2.Wherein, exhaust apparatus 2 is arranged on the top of sintering equipment 1, and exhaust apparatus 2 is for discharging interior the produced waste gas of sintering equipment 1, the jacket 3 that has upper and lower two ends all to seal in the outer cover of exhaust apparatus 2, like this, the outside of the inside of jacket 3 and exhaust apparatus 2 forms annular heat runner 4.The cylindric body that jacket 3 is integral type, the upper left side of jacket 3 is provided with air inlet 31, the lower right of jacket 3 is provided with gas outlet 32, gas outlet 32 is stretched in sintering equipment 1, and the temperature of the air-flow entering from air inlet 31 reduces, and low-temperature airflow enters after annular heat runner 4, understand the outer wall generation heat exchange with exhaust apparatus 2, fully absorb the heat of exhaust apparatus 2, and be elevated to certain temperature, finally by gas outlet 32, enter sintering equipment 1.In order to make air-flow absorb more fully the heat of exhaust apparatus 2 and to prevent jacket 3 distribute heats, on the inwall of jacket 3 and the outer wall of exhaust apparatus 2, intersect and be provided with flow-stopping plate 7, and on the outer wall of jacket 3, be provided with for heat insulation separation sleeve 8, under the effect of flow-stopping plate 7, air-flow is longer in the holdup time of annular heat runner 4, and heat absorption capacity promotes greatly.
Embodiment bis-:
As shown in Figure 3, different from embodiment mono-, the present embodiment is designed to split type circle-shaped body by jacket 3, and jacket 3 comprises the first jacket 5 and the second jacket 6.Particularly, the first jacket 5 and the second jacket 6 are from top to bottom successively set on the outside of exhaust apparatus 2, the gas outlet 32 of the first jacket 5 communicates with the air inlet 31 of the second jacket 6, because the upper temp of exhaust apparatus 2 is lower than temperature of lower, the air-flow flowing out from the first jacket 5 enters the second jacket 6 absorption portion heat again.This set mechanism, makes the Btu utilization of exhaust apparatus 2 more reasonable.
As mentioned above, a kind of NbFeB sintered equipment of the present utility model, the outer cover of exhaust apparatus has jacket, form Packed annular heat runner, the air-flow that enters annular heat runner can fully absorb the heat of exhaust apparatus, and enters sintering equipment from gas outlet, takes full advantage of like this waste heat of waste gas in exhaust apparatus, greatly improve the temperature in agglomerating plant, and then improved the thermal efficiency of agglomerating plant.
Below be only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
