Description
Technical field
The utility model belongs to the coater oven technical field, is specifically related to a kind of novel energy-saving environment-friendly coater oven system.
Background technology
The rapid development of economy of current China brings the high-speed development of packing industry, and coating apparatus is the main infrastructure device of the preceding production equipment of seal in the printing packaging industry.But there is the deficiency of following several respects in existing coating machine:
1, during the work of traditional coating machine, the fresh air that baking oven is outer is inhaled and is sent into electric heater unit, air heat intensification after-blow is carried out drying to the coating materials in the baking oven, all be discharged to hot blast in the baking oven outdoor afterwards, like this, cause the waste gas that contains a large amount of heat energy and volatile solvent gas directly to be discharged in the air, both caused the pollution of air, waste a large amount of heat energy again.
2, for above-mentioned reasons, people once attempted a part of air draft in the baking oven is taken back by bypath valve the air inlet of heat exchanger, though saved the energy like this, but cause dust granule, solvent crystal grain in the baking oven hot blast to get back in the baking oven with the hot blast secondary cycle again simultaneously, coating materials in the baking oven is caused secondary pollution, influenced coating quality.Simultaneously,, when the concentration of the volatile solvent gas in accumulating in baking oven and electric heater unit acquires a certain degree, may blast, therefore have serious potential safety hazard owing to recycling for a long time of the hot blast that contains volatile solvent gas.
3,, in order to finish heating in a short period of time, just must strengthen the power of electric heater unit, thereby increase the power capacity burden of factory because the air temperature difference of turnover electric heater unit is too big.In addition,, have influence on drying effect to a certain extent,, just must improve air velocity, film is dried with the hot blast of " powerful " therefore in order to reach drying effect owing in the indoor air certain humidity is arranged.And the flow velocity that passes through the air of heat exchange elements in the heat exchanger is too high, causes heat exchange elements and air very brief time of contact again, makes the heat exchanger effectiveness of electric heater unit low.
4, in the baking oven of existing coating machine, it is from being positioned at the strip blowing mouth air intake of baking oven roof central authorities, from being positioned at the return air inlet air draft of baking oven the right and left that the oven dry air-flow blows the air draft mode.This structure and working method have caused baking oven central authorities inconsistent with the blast of position, the baking oven left and right sides, and promptly the positive blast of baking oven central authorities is big, and the little and negative blast of the positive blast of the right and left of baking oven is big, therefore make the film in the baking oven produce shake up and down easily.In addition,, fail to form pneumatic shovel formula air-flow, reduced drying effect widely, make above-mentioned the 3rd problem aggravation at film surface because the airflow direction of working chamber is unreasonable in the baking oven.

Described gas-filtering device also can be the photochemical catalyst air cleaning unit, and this photochemical catalyst air cleaning unit includes: the washable screen pack that is used to remove the antibacterial air filter of the bacterium in the air, is made of fibrage, be used to the deodorization filter removing the photochemical catalyst collector of trickle dust and VOC and be used to remove the volatile solvent molecule.
Every joint baking oven is provided with seven strip blowing mouths and 28 circular return air short tubes, and 28 circular return air short tubes are arranged as seven row, and every row is provided with four circular return air short tubes.
The utlity model has following advantage and effect:
1, the utility model is provided with the energy recovery interchanger, high-temp waste gas is discharged by exhaust steam passage, outdoor bright wind is sucked by bright wind passage, because bright wind passage and exhaust steam passage are only isolated by metallic walls, and the discharge currents of high-temp waste gas is opposite to the flow direction that enters with outdoor bright wind, so fresh air that sucks and the outdoor high-temp waste gas heat exchange fully of discharge, fresh air to firm intake system tentatively heats up, the outdoor bright wind-warm syndrome degree of suction is improved as much as possible, because most of hot blast is constantly recycling in the baking oven internal system, have only small amount of exhaust gas to discharge with the form of low temperature, so being coated with the energy consumption of big vast case is significantly descended, the a large amount of heats that contain in the high-temp waste gas are utilized once more, improve the heat energy utilization rate, save the energy, also can reduce insulation cost simultaneously pipeline.
2, the gas-filtering device in the utility model has following effect: a, realizes the purification of air by the multistage filtering net; B, can adsorption filtration fall the volatile solvent gas in the circulating air, simultaneously by the continuous supply of outdoor bright wind, the concentration that can guarantee volatile solvent gas in the baking oven gas is in safe range; C, filter of the present utility model improve hot blast velocity of liquid assets in pipeline by axial flow blower, thus also reduced indirectly blow in the baking oven air exhauster pressure loss, reduce in the baking oven and blow the air exhauster power capacity; D, screen pack can be unpicked and washed, and handled easily is increased work efficiency.
3, the utility model distributes alternately strip blowing mouth in the baking oven and return air short tube by rational oven interior fluid design.Like this, greatly reduce baking oven working chamber air pressure inside degree of irregularity.And, during work, the strip blowing mouth forms positive blast, and the return air short tube forms negative blast, after ejection in HTHP hot blast each strip blowing mouth from baking oven, siphoned away by the return air short tube rapidly, because the opening of strip blowing mouth and return air short tube lower end all is positioned at the diapire of air-inlet cavity, so the path of air-flow in working chamber is arc, the arc starting point is positioned at the strip blowing mouth, the arc terminal point is positioned at the opening of return air short tube lower end, thereby forms a kind of pneumatic shovel formula air-flow at film surface; Pneumatic shovel formula air-flow brushed film surface fast, promptly be expelled back into the return air chamber again, can fast and effeciently carry out drying, and the pressure that forms at film surface is very little film surface from the return air short tube, and each site pressure is even, thereby avoids causing the shake of film.So-called pneumatic shovel formula air-flow is meant that the path is the air-flow of arc, and the air-flow of this arc at film surface through out-of-date, it flows to basic parallel with film surface, as shoveling film surface, so title " pneumatic shovel formula air-flow ".
4, since the coater oven system in the course of the work, be arranged in the gas volatile solvent gas concentration height that the front baking oven is discharged, and the gas volatile solvent gas concentration that is arranged in back baking oven discharge is very low, so in the utility model, the air outlet that will be positioned at the air exhauster of the some joint baking ovens in front is communicated to exhaust steam passage, and the waste gas of this part is drained; All the other air outlets of air exhauster that are positioned at the baking oven of back then are communicated to the air inlet of gas-filtering device, make the waste gas of this part continue to recycle through filtering the back.Like this, both heat energy can be utilized fully circularly, and being controlled in certain safe range of volatile solvent gas concentration in the circulating air safety can be guaranteed again.
In a word, the utility model can energy savings, reduce the high-temperature gas discharging, reduce air pollution, increase work efficiency, guarantee product quality, solved existing coating apparatus energy consumption big, seriously polluted, have difficult problems such as potential safety hazard, the inconvenience of baking oven cleaning operation.
