Description
Technical field
The utility model relates to the technical field of MLCC firing process.
Background technology
It is one important procedure of MLCC manufacture process that MLCC, promptly conventional chip capacitor, its high temperature burn till.Before burning till, must handle through the binder removal of product.The binder removal principle mainly be with product by heating to 300-400 ℃ so that product is separated out at the solvent composition in the manufacture process before, the high temperature that is beneficial to product burns till sclerosis.The high temperature of MLCC product burns till by MLCC atmosphere tunnel firing furnace and finishes.Existing way is to use the binder removal case independently to finish binder removal, transfers to by manually-operateds such as flaps and carries out sintering on the atmosphere firing furnace.Production process fails to realize full automation, and production efficiency is low, and can not burn till the quality that also can influence product behind the binder removal at once.
The utility model content
The purpose of this utility model is to remedy the deficiencies in the prior art, realizes that single stove finishes binder removal and burning till once.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme: the disposable MLCC atmosphere tunnel firing furnace of finishing binder removal and burning till, comprise tunnel type firing furnace, electrical control equipment, propulsion system, rotary track, it is characterized in that: also comprise tunnel type binder removal stove, described rotary track penetrates binder removal stove burner hearth and the firing furnace burner hearth forms the single-revolution loop.
Pending product is loaded in the push pedal, and push pedal is positioned on the described rotary track and is pushed in the burner hearth along rotary track by described propulsion system.
Described binder removal furnace body is assembled by plurality of sections, makes installation, maintenance more convenient.
Described binder removal furnace body is made up of intensification heating region, constant temperature binder removal zone and cooling cooled region, 16 meters of length overalls, and being divided into is seven warm areas, each warm area top is respectively arranged with the heating element heater of independent control.Reasonably warm area quantity has been guaranteed the realization of binder removal process curve, because the binder removal time shortens the more compact and reasonable that causes warm area to design.
The sidewall of the furnace body of described binder removal stove is provided with suction opeing, the air inlet that connects exhausting system, and the body of heater roof is provided with the circulating fan inlet.Because can produce binder removal oil in the binder removal process, binder removal oil is a kind of organic deep-etching and inflammable liquid, and body of heater itself is the high temperature mode of heating, thus suction opeing and air quantity be provided with very crucial.
The utility model is to utilize the track of himself to transform increase binder removal heating arrangements on the atmosphere continuous tunnel furnace, make the shared rotary track of binder removal heating furnace and firing furnace, product advances sintering furnace at once continuously behind binder removal, need not carry out the flap operation, realize that single stove finishes binder removal and burning till once, thereby improved product quality greatly, realized that single stove finishes binder removal and burning till once.The utility model not only makes technology more rationalize, and has both reduced the conveyance time of product simultaneously, has also improved and has burnt till efficient, and main is the consumption of having saved the binder removal electricity consumption greatly, has improved economic benefit significantly.The utility model is raised labour productivity, is lowered labour cost, reduces the input (as: binder removal plate etc.) of a large amount of machining tools; Reducing product in transit is the loss that causes because of the people.
Compared with prior art, the advantage that the utlity model has can see the following form 1,
Table 1: the electric consumption of using of transforming the back saving
By last table as can be known, behind enforcement the utility model, the electricity consumption that the every batch products of binder removal can be saved 94.4kwh, by working as 300 batches of calculating of every month output of the every stove of predecessor company, every bar oven can be saved the electricity consumption of 28320KWh in every month.By 0.65 yuan of calculating of every degree electricity, every bar oven can be saved 18408 yuan in every month, and can save 216576 yuan every year, and energy-saving effect is remarkable.
Secondly, implement the input that the utility model also can reduce a large amount of machining tools, as the binder removal plate, former each binder removal case need dispose 1200 blocks of binder removal plates, every long stove need mate 6 binder removal casees, therefore, and to the input that can save 7200 blocks of binder removal plates after the sintering furnace transformation of separate unit tunnel; By 20 yuan of calculating of every block of binder removal plate (about 1 year of the life-span of binder removal plate), every continuous tunnel furnace can be saved 7200*20=144000 unit every year after the project implementation.
Once more, can reduce product after the project implementation is the loss that causes because of the people, reduces product and collapses the quality problems that the limit collapses the angle.Originally each binder removal case is finished and is needed to carry out flap behind the binder removal and carry out sintering to the atmosphere firing furnace, collapse the limit and collapse the angle ratio because of flap causes about every batch about 4～5/5000, after the project implementation, advance sintering furnace after the binder removal stove at once continuously, need not carry out the flap operation, thereby improved product quality greatly, by 1,500 ten thousand calculating of every bar oven output every day, transform the waste product that the every bar oven in back can reduce 4～5/5000*1500*30=36～450,000 granule products, pressing 13.5 yuan/K of product average price calculates, every bar oven can be saved 4860～6075 yuan in every month after the project implementation, can save 58320～72900 yuan every year.Simultaneously, because of reducing the generation of product appearance defective, operation is easier after making carries out the outward appearance judgement to product, has reduced the probability of choosing the outward appearance product;
Can reduce labour intensity after the transformation, lower labour cost, originally the workman need once adorn alms bowl and a flap, the firing furnace sintering of being allowed for access, only need once adorn alms bowl after transforming and get final product, the original big and heavy travel position of workman is simplified greatly, reduce means of transport and personnel simultaneously and dropped into, simplify working procedure, thereby improved efficiency.
In sum, transform the every continuous tunnel furnace in back and can save 216576+144000+58320=418896 unit every year, can improve product quality greatly simultaneously, increase work efficiency.
