Description
Technical field
The utility model belongs to glass manufacturing equipment, specifically a kind of novel texture large drawing amount rolling press.
Background technology
The equipment producing ultra-white photovoltaic glass is a kind of rolling press with upper and lower two rollers.The glass raw sheet that current rolling press is produced is wide general at 2200MM(± 200MM), cutting effective width of slab is at 2000MM(± 200MM).Single line drawing amount is larger, and glass manufacture cost is lower, and in order to reduce production cost, each glass production enterprise is all improving constantly drawing amount.Usual every day glass drawing amount by formulae discovery below:
Drawing amount D=glass raw sheet wide L* thickness of glass T* pull speed S* glass density ρ
As can be seen from above-mentioned formula, the original plate width of glass directly determines the size of drawing amount, and the original plate width increasing glass increases the most direct method of drawing amount.
The manufacturers of rolling press is mainly German and Chinese in the world at present.The drawing amount of German and Chinese rolling press is generally all less than 150 tons/Heaven's commandments branch line.The major defect of current German rolling press is: 1. the stack external diameter of rolling press use is thin.Be generally between 235 ㎜ ~ 270 ㎜.The advantage that roller external diameter is partially thin is good cooling results, is beneficial to distributing of roll surface temperature.It exists shortcoming is that roller rotating speed is too fast, beating of roller is relatively large, so cause the unstable and glass drawing amount of the thickness of sheet glass can not too large .2. rolling press stack effective surface (the maximum plate of glass is wide) length≤2600MM, produce glass laterally effective cutting specification≤2100MM, in the glass unit time, drawing amount is less.
The major defect of Japanese or Chinese rolling press is: 1. the stack external diameter of rolling press use is thick: general between 270 ㎜ ~ 380 ㎜, and its advantage is that roller footpath big roller rotor speed is slow, good stability.2. many employing supporting plate water tank structures after rolling press home roll, its shortcoming is that supporting plate water tank takes the inner water flowing of water bag, surface wind is held up, and this structure controls to cause glass-board surface to be out of shape because air force is difficult.3. this kind of rolling press stack length≤2600MM, produce glass laterally effective cutting specification≤2100MM, in the glass unit time, drawing amount is less.
In addition, the stack inner inlet type of cooling of current rolling press adopts one end water inlet one end water outlet, belongs to " one-in-and-one-out " or " one enters four goes out " formula structure." one enters four goes out " formula structure, as Fig. 7 shows, the water inlet of taking on the left of stack intakes, and takes the mode of four rising pipes on the right side of stack. and in stack, there is employing four-core to divide water rod that stack inside is divided into four cross water chamber (see figure 8).Cross water chamber for four to be connected with four rising pipes of water side respectively.And " one-in-and-one-out " formula structure water side adopts a rising pipe.This " one-in-and-one-out " and " one enters four goes out " formula structure has problems, and water enters from side, and opposite side flows out, and by the thermal conduction of the outer high temp glass liquid of roller, inflow side inflow temperature is lower, and outflow side leaving water temperature(LWT) is high.Stack is by cooling intensity effect, and side temperature is high, and side temperature is low, thermograde journey asymmetry.
The rolling press of a kind of large drawing amount of present urgent need, stack roll body surface temperature gradient symmetrically property, reduces production cost while guarantee glass quality.
Summary of the invention
