Abstract
The utility model discloses a smoke discharge and colloid discharge device for a LiFePO4 material sintering furnace. The smoke discharge and colloid discharge device comprises a galvanized main smoke pipe, wherein a plurality of galvanized branch smoke pipes are connected in parallel with the pipe body branches of the galvanized main smoke pipe; a V-shaped chimney cover is mounted at the end of each galvanized branch smoke pipe; the V-shaped chimney cover covers each smoke exhaust port of the furnace body; an induced fan and a smoke gas processor are mounted on the galvanized main smoke pipe; an air door capable of adjusting the atmospheric air inflow is further arranged at the front end of the galvanized main smoke pipe. According to the utility model, the air door at the front end of the main smoke pipe and the double adjustment of induced fan contact-separating force enable the generated flue gas and colloid to be timely discharged and the furnace to maintain a certain value; the flue gas discharge of the entire furnace is unobstructed and the pressure of the furnace is stable. Therefore, manufactured materials have favorable performances and the practicability is strong, thereby being worthy of popularization.
Description
Technical field
The utility model relates to a kind of smoke evacuation batching out unit of LiFePO 4 material sintering kiln.
Background technology
LiFePO4 (LiFePO4) material of olivine-type, because the advantage of its low price, non-environmental-pollution, nonhygroscopic, security and Heat stability is good becomes one of lithium ion anode material of at present tool potentiality, by vast scientific research, commercial undertaking are paid close attention to.
The preparation method who uses morely in LiFePO4 (LiFePO4) material industry is high temperature solid phase synthesis.The sintering furnace that anode material for lithium-ion batteries manufacturing enterprise is used both at home and abroad is at present generally pusher furnace.Owing to discharging fume in course of reaction, binder removal amount is larger, if discharged not in time, can cause sintering material oxidation out, and performance is bad.On flue gas colloid the kiln wall and heating element heater that can adhere to that does not have to discharge, so corrosion kiln, electric furnace heating wire blows, and therefore the pre-thermal exhaust of pusher furnace is a problem can not be ignored.
Existing pusher furnace preheating gas extraction system is after each exhaust opening being linked together with pipeline, flue gas and colloid is extracted out with air exhauster.For LiFePO4 village material, due to oxidizable in its sintering process, so need to pass into protective gas in whole sintering process, whole kiln should remain on certain pressure.So in the time using air exhauster, draft is excessive, furnace pressure is difficult to keep, and draft is too small, and exhaust is obstructed.In LiFePO4 production process, can produce a large amount of steam in addition, after steam is discharged by exhaust opening, in the pipeline being connected with exhaust opening, be easy to meet condensation knot, afterwards because Action of Gravity Field flows back to kiln, cause the short circuit of resistance wire, burn short.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of smoke evacuation batching out unit of LiFePO 4 material sintering kiln.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of smoke evacuation batching out unit of LiFePO 4 material sintering kiln, comprise zinc-plated main smoke pipe, many zinc-plated smoke separating pipes in the pipe shaft branch parallel connection of described zinc-plated main smoke pipe, the termination of described zinc-plated smoke separating pipe is provided with V-type chimney cap, and described V-type chimney cap covers on body of heater on each exhaust opening; On described zinc-plated main smoke pipe, air exhauster and flue-gas treater are installed, and the front end of zinc-plated main smoke pipe is also provided with the air door of adjustable atmosphere air inflow.
Further, on described zinc-plated smoke separating pipe, control valve is installed.
The beneficial effect that the utility model reaches:
(1) can regulate by the draft of the air door after main smoke pipe and air exhauster is two, flue gas and the colloid of producing can be discharged in time, and furnace pressure can maintain certain value.
(2) be provided with a V-type chimney cap at each exhaust opening place, can make the steam in flue gas condense at V-type chimney cap inwall, the kiln that can not flow backwards back, thereby the service life of prolongation heating element heater.
(3) fume emission of whole piece kiln is unobstructed, and furnace pressure is stable, thereby makes the material property produced good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the smoke evacuation batching out unit of the LiFePO 4 material sintering kiln the utility model proposes, comprise zinc-plated main smoke pipe 3, many zinc-plated smoke separating pipes 2 in the pipe shaft branch parallel connection of zinc-plated main smoke pipe 3, the termination of zinc-plated smoke separating pipe 2 is provided with V-type chimney cap 1, on zinc-plated smoke separating pipe 2, control valve 21 is installed, V-type chimney cap 1 covers on body of heater 5 on each exhaust opening; Air exhauster 4 and flue-gas treater 5 are installed on zinc-plated main smoke pipe 3, and the front end of zinc-plated main smoke pipe 3 is also provided with the air door 31 of adjustable atmosphere air inflow.
In the utility model; the gases such as the steam that produces in the interior LiFePO 4 material production process of body of heater 6, carbon monoxide, carbon dioxide, ammonia; take out under active force the soft of air exhauster 4; body of heater flue gas enters after V-type chimney cap 1 by exhaust opening; enter zinc-plated main smoke pipe 3 by zinc-plated smoke separating pipe 2 again; urging under dynamic action of the atmosphere that main smoke pipe 3 front ends that the draft of air exhauster 4 and air door 31 regulate enter; flue gas enters after the processing of carrying out flue gas colloid in flue-gas treater 5 again; enter again atmosphere, protected environment.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
