The Mechanics Calculation (such as Strength co-mputation, amount of deflection are calculated) and warming plate THICKNESS CALCULATION of warming plate should be typically carried out in design.Root
Insulation plate thickness is determined according to oven temperature, warming plate usual thickness has 100mm, 125mm and 160mm.Insulation material is conventional to be had
Rock wool, alumina silicate fibre, glass fibre etc., middle insulation material should load full, and its degree of packing is about 120Kg/m3.Chamber body
Wallboard may be designed to pin-connected panel, may be designed as it is skeleton, no matter use which kind of frame mode, all should be provided with heat bridge, with preferable
Ground completely cuts off the transmission of heat, reaches energy-conservation and the purpose of protection work situation.
The flowing of the determination air of hot air circulating system is carried out by blower fan.The air of flowing passes through air filtration
Device, air heater and air channel, are finally sent in dry air channel and spray orifice, it is desirable to which spray orifice wind speed is uniform, uniform temperature fields.Blower fan
It should directly be linked together as far as possible with baking oven air supplying chamber, to reduce along stroke pressure loss and local pressure loss, reduce equipment
Cost, the space reduced required for baking oven.The sectional area in air channel is designed to keep as far as possible in minimum air velocity, air channel
Baking oven have inlet air plenum and be drying chamber between two inlet air plenums provided with exhaust outlet, air intake is provided with tuyere towards drying chamber, enters
Air compartment is provided with blast pipe, and the circulating air opening extraction wind of oven main body is returned again to after heater to blast pipe to follow so as to be formed
Ring is utilized, to play a part of saving the energy；In addition, its air inlet is not directly to matrix (coated product), leading effectively
To, part flow arrangement, cause that product drying is uneven, local overdrying causes the phenomenon that is cracked, crimps, its drying efficiency is low
Under；Because air draft is not smooth, it is too high to easily cause box house solvent gas concentration, causes equipment alarm to shut down even on fire, spray
The effect of mouth is, pressure stability uniform by hot blast wind speed, if forming hot blast when good air flow field sprays in arid region
Velocity perturbation is excessive, then can occur uneven drying phenomenon, and high wind speed region can cause pole piece to shake or produce disadvantage, low wind speed
Area can make it that pole piece dries not thorough therefore the structure of drying box nozzle is particularly important.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, a kind of oven structure of reduction film surface influence in the present embodiment, including baking oven casing 1, circulated air
Machine 2 and exhaust fan 3, from first to last totally 28 meters of the baking oven casing 1, are divided into the first levelling area of low-temperature zone（Temperature be 80 ° ~
90°）, high temperature section hot setting area（Temperature is 140 ° ~ 150 °）With the second levelling area of low-temperature zone（Temperature be 130 ° ~
100°）, temperature from low to high, then from high to low, air-out passage 4, air-out is provided with three sections of the inside of baking oven casing 1
Passage 4 is evenly arranged and turned on baking oven casing 1, and air-out passage 4 is evenly arranged and is arranged in parallel with the deflector roll 5 of lower section, each
Air-out passage 4 is provided with directly over deflector roll 5 and between adjacent deflector roll 5, the air-out passage 4 directly over deflector roll 5 is between the upper and lower
Away from for 5cm or so, air-out passage 4 between adjacent deflector roll 5 and film surface between the upper and lower away from for 10cm or so.The circulated air
Machine 2 is connected by airduct with the air-out passage 4 in baking oven casing 1, and exhaust fan 3 is connected with baking oven casing 1, exhaust fan
3 air outlet is connected with the air inlet of circulating fan 2.
The air-out passage 4 is gradually down shunk by top so that the cross section of whole die cavity is trapezoidal, and hot blast is in rectangle
The centre position speed highest in region, the reason for this is due to entry position, centre position is gradually reduced toward circumferential velocity, be by
Raised in hot blast as the reason for decaying rectangular areas corner wind speed is presented in diffusion velocity, be because after hot blast and collision with wall
Circle round, vortex surrounding local velocity increase rectangular areas are pointed at speed nearby with tapered face to be had on mutation, tapered face
Hot blast can be observed gradually to move to outlet, and speed is increasing, and air-out passage 4 is a resistance element, can cause energy
Nearby hot blast speed has big mutation to the straight seamed edge section wedge angles of amount loss, and energy loss is more, therefore exhaust passage is led into the two of 4
Side uses round edge instead instead of straight seamed edge, chamfering R=5mm, and the jumping phenomenon of the neighbouring hot blast of round edge is not obvious after improvement, circle
Although the arm of angle is to hot blast speed also decrease to some degree, from the excessive also smoother of wind speed in the speed of section gradually
The change of hot blast is more uniform in contracting passage, is gradually incremented by by certain gradient, is influenceed smaller by the factor such as vortex and hot blast convolution.
The bottom of air-out passage 4 is the bar shaped air outlet formed by two sides, and air-out passage 4 plays current balance function using tapered channels, made
The air wind speed of ejection is uniform, because the first levelling area and the second levelling area are located at low-temperature zone, if done by the way of direct-injection
It is dry to be impacted to film surface, thus by positioned at the bar shaped air outlet of the first levelling area and the air-out passage 4 in the second levelling area with
Angle between film surface is set to 45 ° so that dry wind blows to film surface with 45 ° of angle of inclination, and positioned at hot setting area
It is 90 ° of vertical angles between the bar shaped air outlet and film surface of air-out passage 4, while the air force in the first levelling area is 5m/s,
Dry-heat air is set steadily to heat film surface, the air force in hot setting area and the second levelling area is 8-10m/s, using big
Air quantity destroys the still air layer on dry surface, makes circulating air impingement drying.
Under normal circumstances, link position wind speed is maximum between air-out passage and airduct, and for example airduct is located in air-out passage
Between, then the wind speed in centre position is maximum, then gradually successively decreases to both sides, so causes the air quantity of bar shaped air outlet different so that
The wind-engaging of film surface is uneven, so that drying effect is influenceed, therefore, being evenly arranged with dividing plate in the die cavity of the air-out passage 4
6, dividing plate 6 is located at the bottom of air-out passage 4, and the top of dividing plate is hanging, and the height of the dividing plate 6 is the 0.1 of the height of air-out passage 4
~ 0.2 times.
In addition to the implementation, present invention additionally comprises have other embodiment, all use equivalent transformation or equivalent replacements
The technical scheme that mode is formed, all should fall within the scope of the hereto appended claims.
