Abstract
The utility model discloses a waste heat utilization device of an industrial sintering furnace, which comprises a draught fan (1), a waste heat collecting system and a drying system, wherein the waste heat collecting system is connected with an inlet of the draught fan (1), and the drying system is connected with an outlet of the draught fan (1). The waste heat collecting system includes a plurality of branch heat collecting flues (2) and a main heat collecting flue (3), wherein the branch heat collecting flues (2) arranged on the top of a sintering furnace cooling area (8) are communicated with the sintering furnace cooling area (8), and the main heat collecting flue (3) communicated with the branch heat collecting flues (2) is connected with the draught fan. The drying system includes a heating flue and a semi-closed device (4). The device recycles waste heat of the sintering furnace cooling area by the aid of the waste heat collecting system, and leads the heat of the cooling area to the position of a single push plate in front of an inlet of the sintering furnace and dries a blank placed inside the semi-closing device by the aid of the drying system. The dried blank enters the sintering furnace to be sintered so that the qualification rate of the blank is increased.
Description
Technical field
The utility model relates to the production residual heat using device in the sintering art, relates in particular to the sintering oven production afterheat utilization device in the permanent-magnet ferrite sintering process.
Background technology
Existing permanent-magnet ferrite sintering process is: at the sintering oven heating zone blank is removed moisture, make sinter obtain high magnetic characteristics and mechanical property in the sintering oven high-temperature region, at the sintering cooling area sinter is cooled off.The heat of sintering oven cooling area in process of production can be a large amount of outwards distribute, cause the waste of resource, thereby very unfortunate.
Summary of the invention
Problem to be solved in the utility model provides a kind of afterheat utilization device, can reasonably utilize the waste heat of sintering oven cooling area, and it is low to make that energy consumes, and has saved resource, has improved the qualification rate of blank.
The residual heat using device of industrial sintering oven of the present utility model comprises air-introduced machine, the residual heat collection system that links to each other with the air-introduced machine inlet, exports the drying system that links to each other with air-introduced machine.
The residual heat collection system comprises the general collection heating flue that is arranged on sintering oven cooling area top and divides flue, divide flue to communicate and link to each other with air-introduced machine with thermal-arrest with some thermal-arrests that it communicates.
Drying system comprises heat supply flue and semiclosed device.Semiclosed device is " Jiong " shape, is arranged on preceding single push pedal place of sintering oven inlet, and blank is placed on wherein.The heat supply flue comprises total heat supply flue that some heat supplies of being arranged on single push pedal below divide flue, divide flue to communicate with heat supply and link to each other with air-introduced machine.
This device reclaims the waste heat of sintering oven cooling area by the residual heat collection system, by drying system the heat of cooling area is caused single push pedal place before the sintering oven inlet again, and the blank that is placed in the semiclosed device is dried.Blank after the oven dry enters and carries out sintering in the sintering oven, thereby has improved the qualification rate of blank.
The utility model has changed lets alone the phenomenon that sintering oven cooling area heat runs off in the past, by the blank that the waste heat with cooling area is delivered in the semiclosed device it is dried, the as many as heating zone that prolonged, thereby improved the qualification rate of blank, also improved the sintering efficient of sintering oven simultaneously.
Description of drawings
Fig. 1 is the front view of the utility model residual heat using device;
Fig. 2 is the vertical view of the utility model residual heat using device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed introduction:
From Fig. 1 and Fig. 2 as can be known, the residual heat using device of the utility model industry sintering oven comprises air-introduced machine 1, the residual heat collection system that links to each other with air-introduced machine 1 inlet, exports the drying system that links to each other with air-introduced machine 1.
The residual heat collection system comprises the general collection heating flue 3 that is arranged on sintering oven cooling area 8 tops and divides flue 2, divide flue 2 to communicate and link to each other with air-introduced machine with thermal-arrest with some thermal-arrests that it communicates.
Drying system comprises heat supply flue and semiclosed device 4.Semiclosed device 4 is " Jiong " shape, is arranged in the preceding single push pedal 7 of sintering oven inlet, and blank 10 is placed on wherein.The heat supply flue comprises total heat supply flue 5 that the some heat supplies that are arranged on single push pedal 7 belows divide flue 6, divide flue 6 to communicate and link to each other with air-introduced machine with heat supply.
Device of the present utility model makes the waste heat of sintering oven cooling area 8 cause preceding single push pedal place of sintering oven inlet by flue and air-introduced machine, the blank 10 that is placed in the semiclosed device 4 is heated, make that the most of moisture of blank 10 is just discharged at semiclosed device, and then enter sintering oven heating zone 9 and remove moisture, thereby blank 10 is easily dried, and makes the sinter qualification rate in the sintering oven rise to present 98% by former 97%.Simultaneously because the minimizing of blank moisture, make push pedal speed had ready conditions by former general 14 " 30 '/plate be promoted to present general 12 " 30 '/plate about, the sintering tonnage of sintering oven is increased.This kind device does not limit to and is used in permanent-magnet ferrite and produces sintering art, and it can be widely used in Production of Ceramics sintering and other industrial production sintering arts.
