Abstract

The utility model discloses a double-flow water-cooled calendering roller, which comprises an outer roller, an inner roller and a water inlet pipe, wherein the outer roller is connected with the inner roller through flanges at two ends of the calendering roller; an annular cooling cavity is formed between the outer roller and the inner roller; a roller shaft is arranged at the end part of the outer roller; the cooling cavity is divided into at least two independent cavities through sealing partition boards; water outlet coiled pipes are arranged at two ends of the outer roller; and one parts of the independent cavities are communicated with a left end water inlet pipe and a right end water outlet coiled pipe and the other part of the independent cavities are communicated with a right end water inlet pipe and a left end water outlet coiled pipe. When the double-flow water-cooled calendering roller is used, cooling water enters at the same time from water inlet pipes at the left end and the right end and the cooling water in the adjacent independent cavities has opposite flow directions and flows in and flows out in two directions, so the cooling efficiency is greatly improved, the surface temperature of the outer roller is reduced, the surface temperature uniformity of the calendering roller is improved, calendering glass is uniform and consistent in thickness, and the qualified rate of glass products is increased.

Description

A kind of two-way flow water-cooled stack

Technical field

The utility model belongs to solar energy ultra-white glass manufacturing apparatus technical field, particularly a kind of two-way flow water-cooled stack.

Background technology

Solar energy ultra-white glass is to utilize the extruding be installed in the upper and lower stack on the rolling press and cooling effect and be shaped to sheet glass from the glass metal of molten state; Stack relies on and cools off through the water coolant in its inner chamber; The type of cooling directly affects the homogeneity of roller surfaces temperature, and then the calendering quality of glass is exerted an influence.General stack adopts the unidirectional water-cooled type of cooling, and water coolant flows into, flows out from the other end from stack one end, because the stack cavity is bigger, water coolant can only contact with the part cavity inner wall in the stack rolling process, and evaporation efficiency is lower.Simultaneously, receive the influence of high-temperature fusion glass metal, the water coolant intensification of in flow process, absorbing heat causes stack surface water intake end temperature to be lower than the water side temperature, forms bigger temperature head, causes the rolled glass became uneven, has reduced the good article rate of glassy product.

The utility model content

The purpose of the utility model provides a kind of evaporation efficiency height, the uniform two-way flow water-cooled of stack surface temperature distribution stack.

For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of two-way flow water-cooled stack, comprise outer roller, interior roller and water inlet pipe, and outer roller is connected with the flange of interior roller through two ends; Form the ring-type cooling chamber between outer roller and the interior roller; Outer roll end is provided with roll shaft, and said cooling chamber is separated into two individual cavity at least through seal diaphragm, and the outer roller two ends are provided with the water outlet coil pipe; The part individual cavity is connected with left end water inlet pipe, right-hand member water outlet coil pipe, and another part individual cavity is connected with right-hand member water inlet pipe, left end water outlet coil pipe.

Said cooling chamber is separated into the even number individual cavity through seal diaphragm; Half individual cavity left end at interval is communicated with the left end water inlet pipe, right-hand member is communicated with right-hand member water outlet coil pipe, and second half individual cavity right-hand member is communicated with the right-hand member water inlet pipe, left end is communicated with left end water outlet coil pipe.

Said cooling chamber is separated into eight individual cavity through seal diaphragm; The individual cavity left end of four spaces is communicated with the left end water inlet pipe, right-hand member is communicated with right-hand member water outlet coil pipe, and the individual cavity right-hand member of other four spaces is communicated with the right-hand member water inlet pipe, left end is communicated with left end water outlet coil pipe.

Compared with prior art, the utility model has the advantages that: in the utility model, outer roller is connected with the flange of interior roller through two ends; Form the ring-type cooling chamber between outer roller and the interior roller; Outer roll end is provided with roll shaft, and said cooling chamber is separated into two individual cavity at least through seal diaphragm, and the outer roller two ends are provided with the water outlet coil pipe; The part individual cavity is connected with left end water inlet pipe, right-hand member water outlet coil pipe; Another part individual cavity is connected with right-hand member water inlet pipe, left end water outlet coil pipe, guarantees that water coolant fully contacts with cavity inner wall, has improved evaporation efficiency greatly; The water coolant two-way flow has reduced the outer roller surface temperature difference, improves stack surface temperature homogeneity, thereby makes rolled glass thickness uniformity, improves the good article rate of glassy product.

Embodiment

Like Fig. 1, Fig. 2 and two-way flow water-cooled stack shown in Figure 3; It comprises outer roller 2, interior roller 1 and water inlet pipe, and outer roller 2 is connected with the flange 5 of interior roller 1 through two ends, between outer roller 2 and interior roller 1, forms the ring-type cooling chamber; Be provided with roll shaft 3 in outer roller 2 ends, be used for the rolling of stack.Cooling chamber is separated into eight individual cavity through seal diaphragm 7; The left end of the individual cavity 11,12,13,14 of four spaces is communicated with left end water inlet pipe 6, right-hand member is communicated with right-hand member water outlet coil pipe 4, and the right-hand member of the individual cavity 21,22,23,24 of other four spaces is communicated with right-hand member water inlet pipe 61, left end is communicated with left end water outlet coil pipe 41.

The utility model in use, water coolant is intake from the water inlet pipe of right ends simultaneously, the direction of arrow is water (flow) direction among Fig. 1; Water (flow) direction in the individual cavity 11,12,13,14 flows out from right-hand member water outlet coil pipe 4 from left to right at last, and the water (flow) direction in the individual cavity 21,22,23,24 then is from right to left; Flow out from left end water outlet coil pipe 41 at last; Because the intravital flow of cooling water of adjacent separate chamber is in the opposite direction, form water coolant bidirectional flow influent stream and go out, improved evaporation efficiency greatly; Reduce outer roller 2 surface temperatures, improve stack surface temperature homogeneity.
