According to the cooling device applied to the formation of the liquid crystal glass base plate, disclosed by the utility model, by aiming at the productive practice that the temperature of the middle part of the glass base plate is higher than the temperature of the two ends of the glass base plate, the diameter of the middle part of the outer pipe is increased so that the cooling area is relatively increased, the temperature of the middle part of the glass base plate is beneficial to being reduced, the quality factors such as stress and warpage are optimized, and the quality of the glass base plate is improved.
Description
Technical field
The utility model relates to the liquid crystal glass base production technical field, relates in particular to a kind of refrigerating unit for the liquid crystal glass base moulding.
Background technology
In the production process of liquid crystal glass base, glass metal through platinum channel homogenizing, clarification enters pressing section, in shaping furnace, need to insert the direction that water-cooled tube makes glass substrate cooling, typing fast, controls rate of cooling and adjust the glass substrate bending.
In daily production process, the relative both sides of the medium temperature of glass substrate are higher, because the thermograde in the middle of substrate strengthens, therefore the quality factors such as the stress of substrate, warpage caused impact.And the caliber of existing water-cooled tube equates everywhere, can not be effectively for the actual solution of above-mentioned production and adjustment moulding quality problem.And device does not have handle, is not easy to operation, has potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is to provide the refrigerating unit that a kind of realistic condition of production, easy to operate, safe and reliable being used for are adjusted the liquid crystal glass base quality.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: be used for the refrigerating unit of liquid crystal glass base moulding, comprise outer tube, inner tube, water inlet pipe and return water pipe; Inner tube is enclosed within the inner chamber of outer tube, is provided with cavity between outer wall of inner tube and outer tube wall; The inner tube head end is connected with water inlet pipe, and the inner tube end is provided with posticum; The outer tube end closure, the outer tube head end is connected with return water pipe, and the caliber of outer tube is middle slightly, two ends are thin.
As preferably, inner tube is connected with the right angle with water inlet pipe, and water inlet pipe is connected with outer tube wall and passes, and makes water inlet pipe curve operation handle arm.
As preferably, outer tube is connected with the right angle with return water pipe, makes return water pipe curve operation handle arm.
As preferably, comprise that also the insulation closeouts is ring-type, is looped around the outer wall of described outer tube for gap between shutoff outer tube and shaping furnace reserving hole and resistant to elevated temperatures insulation closeouts.
As preferably, the periphery of insulation closeouts is wrapped up that Velveting, the inner filling insulating cotton.
As preferably, outer tube and inner tube are made by stainless material.
Cooling-water duct flows to inner tube from water inlet pipe, then enters cavity between outer tube and inner tube from the posticum of inner tube end, then flows out from return water pipe.
The beneficial effects of the utility model are:
Actual for the production that the medium temperature of glass substrate relative both sides are higher, strengthen the caliber in the middle of outer tube, corresponding increase cooling area helps to reduce the medium temperature of glass substrate, has optimized the quality factors such as stress and warpage, has improved the quality of glass substrate.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation that the utility model is used for the refrigerating unit embodiment of liquid crystal glass base moulding.
Fig. 2 is the sectional view at Figure 1A place.
In figure, the 1-inner tube, the 2-posticum, the 3-outer tube, 4-is incubated closeouts, 5-insulating cotton, 6-water inlet pipe, 7-return water pipe.
Embodiment
As shown in Figure 1, this device is comprised of inside and outside two water pipes, and inner tube 1 is enclosed within the inner chamber of outer tube 3, leaves cavity between inner tube and outer tube.Inner tube 1 end has posticum 2.Different from the common water-cooled tube of shaping furnace is: the diameter of outer tube 3 is not isometrical, but the stage casing is thick, two ends are thin, the design of this structure be for liquid crystal glass base in moulding process both sides than middle rapid heat dissipation, the sheet glass two sides temperature with the centre than relative practical condition on the low side, to base plate glass two ends and middle give different amount of cooling water with reach the temperature field evenly, thereby adjust and optimize stress and the warpage of glass substrate.
In Fig. 1, the circulation loop of water coolant is as follows: exterior cooling water enters inner tube 1 from water inlet pipe 6, then enters outer tube 3 from posticum 2, then flows out from return water pipe 7, forms cooling water circuit.
All water pipes all adopt stainless material to make.
In Fig. 2, be useful on the insulation closeouts 4 in gap between shutoff outer tube and shaping furnace reserving hole at return water pipe 3 outer wall covers, the insulation closeouts is that high temperature material is made, its periphery is wrapped up that Velveting, inner filling insulating cotton 5 plays insulation, heat-blocking action, reduces the heat lost by radiation at hole.
During use, within this device was inserted the shaping furnace reserving hole, it was simple in structure, be convenient to adjust and operation.
The present embodiment adopts the bilayer structure of outer tube sleeve inner tube, makes water coolant pump circulation in pipe, and has strengthened the stage casing diameter of outer tube, to increase the cooling performance in stage casing.
