Description
Technical field:
The present invention relates to radium-shine film processing technique field, particularly laser film painting and coating air-dry method and equipment.
Background technology:
In the process of the radium-shine film of production and processing, it is radium-shine film to be carried out air-dry that a process is arranged, and when air-dry, adopts the hot blast with certain heat.At present, radium-shine film is being carried out in the air-dry process electrothermal tube is installed on air intake passage, utilizing electric energy to carry out pre-thermosetting hot blast.Through experiment as can be known, utilize aforementioned manner need consume a large amount of electric resources, cause production cost high; In addition, in the air drying process, contain some chemical substances in the radium-shine coating, directly be discharged in the air and can cause air pollution.Therefore, be necessary very much to improve existing processing technology, improve process equipment simultaneously, to reach the effect that not only can reduce production costs but also can reduce environmental pollution.
Summary of the invention:
One of purpose of the present invention is to provide laser film painting and coating air-dry equipment at the deficiencies in the prior art, and it not only can reduce production costs but also can reach the waste gas emission standard of national regulation.
For achieving the above object, the present invention adopts following technical scheme:
It comprises air-dry stove, and air-dry stove and accessory has air intake passage, air exhaust passage, and air intake passage is provided with electrical heating district, the oily thermal treatment zone, and electrical heating is equipped with electrothermal tube in the district, in the oily thermal treatment zone oil pipe is installed; Air exhaust passage is provided with the combustion chamber, and oil pipe is installed in the combustion chamber, and oil pipe in the oily thermal treatment zone and the oil pipe in the combustion chamber are formed the peripheral passage.
On the described air intake passage air intake blower fan is installed.
The air draft blower fan is installed on the described air exhaust passage.
The beneficial effect of apparatus for drying of the present invention is, it have simple in structure, not only can reduce production costs but also can reach the advantage of national specified discharge standard.
Another object of the present invention is to provide laser film painting and coating air-dry method at the deficiencies in the prior art, and the concrete scheme of this method is as follows:
Earlier the air intake of air-dry stove is carried out preheating with electrical heating; The waste gas burning that air-dry fire grate is gone out utilizes waste gas burning with the heating of the oil in the oil pipe then, utilizes the air intake of the air-dry stove of heated oil heating then.
After oil in the oil pipe is heated, stop the air intake of air-dry stove is carried out electrical heating.
Beneficial effect of the present invention is, utilize electrical heating that air intake is carried out preheating, make radium-shine film when air-dry in air-dry stove the volatilization some chemical substance, when air draft, the combustible in the waste gas is burnt, to reach national specified discharge standard, when waste gas burning, oil in the heating oil pipe, utilize heated oil that the air intake of air-dry stove is heated again, reduced the use of electric energy, can save production cost greatly.
Description of drawings:
Fig. 1 is an operation principle schematic diagram of the present invention
The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing.
The following stated only is a better embodiment of the present invention, does not therefore limit protection scope of the present invention.
The concrete scheme of the radium-shine painting and coating air-dry method of the present invention is as follows:
Earlier with electrical heating the air intake of air-dry stove is carried out preheating, this stage need consume certain electric energy, and simultaneously, radium-shine film volatilizes in air-dry stove that some chemical substance--specifically the coating by radium-shine film is determined; The waste gas burning that air-dry fire grate is gone out then, waste gas after burning can directly be discharged, and reaches national specified discharge standard; Utilize waste gas burning with the heating of the oil in the oil pipe, utilize the air intake of the air-dry stove of heated oil heating then.
Wherein, after the oil in the oil pipe is heated, promptly can stop the air intake of air-dry stove is carried out electrical heating, only keep oily mode of heating, saves energy reduces production costs greatly; Because radium-shine film constantly enters air-dry stove, certain chemical substance of constantly volatilizing, then waste gas can constantly burn, and the oil in the oil pipe can keep being heated; If just start the machine, then need to produce hot blast with Electric heating earlier, when treating that the interior oily temperature of oil pipe can heat air intake, can stop electrical heating.
See accompanying drawing 1, be the apparatus for drying operation principle schematic diagram that is complementary with radium-shine painting and coating air-dry method, it comprises air-dry stove 10, air-dry stove 10 has air intake passage 20, air exhaust passage 30, on the described air intake passage 20 air intake blower fan 25 is installed, on the described air exhaust passage 30 air draft blower fan 32 is installed; Air intake passage 20 is provided with electrical heating district 21, the oily thermal treatment zone 22, and air intake can pass through from one of them thermal treatment zone, also can pass through from two thermals treatment zone simultaneously, certainly, if be not provided with two independently the thermal treatment zone also can; Wherein, electrothermal tube 23 is installed in the electrical heating district 21, utilizes electric energy that air intake is heated, in the oily thermal treatment zone 22 oil pipe 24 is installed; Utilize the heat energy of oil that air intake is heated; Air exhaust passage 30 is provided with combustion chamber 31, and oil pipe 24 is installed in the combustion chamber 31, and the oil pipe 24 in the oily thermal treatment zone 22 is formed the peripheral passage with the oil pipe 24 in the combustion chamber 31; When waste gas in the combustion chamber during 31 internal combustion, both can reduce and be discharged into airborne chemical substance, reach national specified discharge standard, can the oil in the oil pipe be heated again, when oil flows to the oily thermal treatment zone 22, just can the air intake of air-dry stove 10 be heated, stop electrical heating this moment, just can save a large amount of electric energy.
As shown in FIG., a part of waste gas of air-dry stove 10 can enter air intake passage 20, mixes the effect that reaches preheating with natural wind, makes air intake can promote temperature rapidly.
