Description
Technical field
The utility model is related to a kind of Muffle furnace, particularly a kind of positive electrode sintering Muffle furnace.
Background technology
The thermal field temperature difference is the important technology index of Muffle furnace, and the thermal field temperature difference very little of the measured Muffle furnace of matter ensure that
The uniformity of temperature, this is extremely important for the material to be sintered.In anode material for lithium-ion batteries（Such as cobalt acid lithium, three
First material, LiMn2O4 etc.）Production in, material is very sensitive to temperature, for cobalt acid lithium, and the less temperature difference will
Cause different properties of product occur, influence the uniformity of material.Therefore, the sintering of positive electrode is being carried out using Muffle furnace
In, it is ensured that the uniformity of Muffle in-furnace temperature is extremely important, particularly also needs to be passed through atmosphere in sintering process（Generally compress
Air or bottled gas）, further influence the thermal field temperature difference of Muffle furnace.In the prior art, Muffle furnace thermal field excessive temperature differentials,
Under aeration status, the defect is especially protruded.
The content of the invention
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, providing a kind of positive electrode sintering
Use Muffle furnace.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of positive electrode sintering horse
Not stove, including body of heater；The furnace interior space is burner hearth；The burner hearth arranged on left and right sides is respectively connected with a gas handling system,
And two gas handling system positions are relative；Temperature-sensing element and multiple heating element heaters are provided with the burner hearth；Offered on the body of heater
Fire door and gas outlet.
The fire door, gas outlet are separately positioned on the body of heater leading flank and trailing flank；The gas outlet is arranged on institute
State rear door top middle：The gas handling system of left and right two comes out from gas outlet again after carrying out sufficient collisional mixing, adds
Arrival area and residence time of the gas in Muffle furnace, can effectively ensure that the thermal field uniformity of Muffle furnace.
Described two gas handling systems left surface respectively with the body of heater, right flank bottom middle are connected, and gas is from stove
Thorax bottom enters, and is further ensured that gas effectively evenly reaches each position of burner hearth.
The gas handling system includes being connected with body of heater side, and the inlet channel connected with the burner hearth；It is described enter
Gas passage end is connected with air inlet, and the air inlet is stretched into the burner hearth；The admission line other end or air inlet
Flowmeter is installed in passage.
The inlet channel is located in zone of heating/heating system, and zone of heating or heating system play the work of preheated gas
With the gas temperature that raising enters in burner hearth reduces influence of the compressed gas to fire box temperature uniformity.
The air scoop width is more than the inlet channel internal diameter, because air inlet diameter becomes big, compared in inlet channel
Gas, reduce gas flow rate, and disperse the gas entered in Muffle furnace, the atmosphere inside Muffle furnace is changed more equal
It is even, meet the demand to atmosphere in material sintering process.
The temperature-sensing element is thermocouple, and the thermocouple is stretched into the middle part of the burner hearth from the upper of furnace body, close to material
The sintering region of material, the temperature of test can more preferably represent the actual temperature of material sintering, according to this temperature, can adjust setting
Temperature with reach material sintering need actual temperature.
The multiple heating element heater is respectively distributed to the left side, right side and rear portion of the burner hearth, and more heating surface is present
The thermal field uniformity of Muffle furnace can be further ensured that.
The heating element heater uses the one or more in resistance wire, Elema, Si-Mo rod.
Compared with prior art, the utility model have the advantage that for：The utility model is in Muffle furnace ventilation shape
Also the thermal field temperature difference is can guarantee that under state, it is ensured that the uniformity of Muffle in-furnace temperature is good.
Brief description of the drawings
Fig. 1 is the example structure schematic diagram of the utility model one.
Embodiment
As shown in figure 1, compressed air（Typically all removed water by cooling driers, so compressed air temperature is compared to normal
Air is relatively low）Entered by inlet channel 6 in Muffle furnace, sinter the atmosphere required for providing for positive electrode, 8 be flow
Meter, mainly plays a part of to regulate and control gas flow, 7 be the zone of heating or heating system for surrounding inlet channel, is risen pre- as needed
The effect of hot compressed air, improves the gas temperature entered in Muffle furnace, reduces compressed gas to muffle furnace uniformity
Influence；5 be air inlet, and air scoop width is more than inlet channel internal diameter, because air inlet diameter becomes big, compared to the gas in air inlet pipe
Body, reduces gas flow rate, and disperses the gas entered in Muffle furnace, the atmosphere inside Muffle furnace is changed evenly, carries
To the demand of atmosphere in high material sintering process.
The utility model flowmeter range ability is 0.1~5 cube m/h.
Gas handling system is located at the bottom centre position of the Muffle furnace left and right sides, and left and right correspondence is present, such intake method
Can make gas effectively uniformly reach Muffle furnace in each position, meet material sintering when to atmosphere the need for.Also, in Muffle
The heating of stove and holding stage, the flow of suitable control gas, because the flowing of gas has more preferably driven the transmission of heat, make whole
The efficiency that heated up inside individual Muffle furnace is faster, it is possible to reduce the thermal field temperature difference inside burner hearth.
Gas outlet 2 is located at the positive middle and upper part at Muffle furnace rear portion；Heating element heater 3 as needed can be located at Muffle furnace a left side,
The several faces of right, forward and backward, certain upper and lower, are normally at left and right, the rear portion of Muffle furnace, and more heating surface, which exists, ensure that
The thermal field uniformity of Muffle furnace, temperature-sensing element 1 uses thermocouple, is deep into burner hearth 10 and hits exactly inside, close to the sintering zone of material
Domain, the temperature of test can more preferably represent the actual temperature of material sintering, according to this temperature, can adjust setting temperature to reach
The actual temperature that material sintering needs.Fire door 4 is opened in the leading flank of body of heater 9.
