Description

TECHNICAL FIELD

[0001] The utility model relates to liquid crystal overflow down-draw method flat plate glass technical field, concretely relates to a kind of liquid crystal glass feed pipe quick cooling regulating device. BACKGROUND

[0002] Overflow down-draw method is one of the main methods of liquid crystal glass substrate production, which is to mix raw materials of a certain proportion uniformly, then heat to molten state in a pool furnace, and transport it to the feed pipe through platinum pipeline, the feed pipe is connected with L tube, the molten glass changes the flow direction through L tube, and enters the overflow tank in the muffle furnace. When the overflow tank is full, the molten glass will overflow along the two sides of the overflow tank to the inclined wall, thereby the two streams of glass frit are combined to form the root of the glass sheet, which is pulled down by the downward pulling equipment below to form a single piece of glass.

[0003] At high temperature, the viscosity of molten glass is relatively small, and the flowability is strong. The flow stability of molten glass not only affects the quality of glass forming, but also affects the safety of equipment. If the flow is too large in a short time, it will cause a huge safety hazard to the equipment. Therefore, in actual production, it is particularly important to control the flow of molten glass. Generally, when the flow is suddenly increased due to factors such as muffle furnace docking, overflow brick wetting, forming blockage and other factors, the operator needs to timely mechanically dredge the glass in the forming area and the annealing furnace to avoid serious consequences caused by large accumulation. However, due to the difficulty in quickly reducing the flow of molten glass in the feed pipe in a short time, simply relying on manual mechanical dredging sometimes cannot completely dredge, and when the glass frit is blocked to the upper part of the forming area, in order to ensure the safety of the equipment, the emergency program is usually started to forcibly disconnect the muffle furnace and the feed pipe. However, sometimes although the muffle furnace and the feed pipe have been completely disconnected, the temperature of the molten glass exposed to the air is still very high, and due to the lack of effective cooling means, it is difficult to achieve rapid cooling of the molten glass, and even to stop flowing.

[0004] In summary, the prior art has very limited means for rapid cooling of molten glass, and it is difficult to stop its flow in a short time. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0020] Referring to Figures 1 to 4 As shown in the drawing, the utility model provides a kind of liquid crystal glass feeding pipe quick cooling regulation device, it includes: driving device 1 and cooling assembly 2, driving device 1 includes driving box 11, and the inside of driving box 11 is equipped with electro-hydraulic push rod 12 and motor 13, and the output shaft end of motor 13 is connected with rotating shaft 131, while the outer end of rotating shaft 131 is connected with straight pipe 16, the upper side of straight pipe 16 is connected with connecting pipe 17, and the outer side of connecting pipe 17 is connected with flow valve 18, cooling assembly 2 includes half pipe 21, and vertical hole 22 is set on the upper side pipe wall of half pipe 21, and inclined hole 23 is set on the inner side wall of half pipe 21, while the outer side wall of half pipe 21 is connected with the outer end of straight pipe 16.

[0021] In the embodiment, driving device 1 and cooling assembly 2 constitute the liquid crystal glass feeding pipe quick cooling regulation device involved in the application.

[0022] The inner side of the semicircular pipe 21 is provided with a feeding pipe, the lower end of the feeding pipe is inserted with an elbow pipe, the other end of the elbow pipe is connected with a muffle furnace, the lower end of the muffle furnace is connected with a lifting platform, and the lifting platform is provided with movable universal wheels with self-locking function.

[0023] Specifically, the elbow pipe is provided in L-shaped structure, the lower end port of the feeding pipe is located on the upper side port of the elbow pipe, and the inner diameter of the upper end port of the elbow pipe is larger than that of the lower end port of the feeding pipe. Secondly, the lifting platform is provided as a hydraulic rod supported on the bottom of the muffle furnace to realize the lifting of the muffle furnace, so that when blockage occurs, the muffle furnace can be moved downward to drive the elbow pipe to separate from the feeding pipe.

[0024] The molten glass liquid passes through the elbow pipe into the muffle furnace from the feeding pipe, and then forms a single thin glass through overflow, down-drawing and traction.

[0025] It should be noted that the upper end of the connecting pipe 17 is connected with a cold air equipment (air conditioner) or a cold water equipment (water chiller), and is connected through a quick connector and a hose. In addition, the end of the straight pipe 16 connected with the rotating shaft 131 is provided as a solid end.

[0026] It should be noted that when sudden emergency situations such as sudden surge of lead-out amount or serious blockage of the forming occur, the muffle furnace should be quickly lowered until the elbow pipe is completely separated from the feeding pipe. At this time, the molten glass liquid has been completely exposed to the air, but the temperature is still high and the flowability is very strong. The molten glass in the feeding pipe continues to enter the elbow pipe. At this time, the elbow pipe cannot be moved outward because the temperature and flow rate of the glass liquid are fast. If the elbow pipe is moved, the molten glass liquid will flow onto the muffle furnace, causing damage to other equipment and even safety accidents.

[0027] As shown in Figure 1 , Figure 2 and Figure 3 , two semicircular pipes 21 are provided, and the opposite ends of the two semicircular pipes 21 are provided as solid ends. One end of one of the semicircular pipes 21 is provided with an insertion block 24, and the other end of the other semicircular pipe 21 is provided with an insertion hole 25. The insertion block 24 is inserted into the insertion hole 25 in correspondence. The outer wall of the semicircular pipe 21 is connected with a flow guide plate 26, and the flow guide plate 26 is provided in arc-shaped plate structure.

[0028] Specifically, the two ends of the semicircular pipe 21 are blind holes, and the material is high-temperature-resistant stainless steel. The specific size and size are determined according to the diameter of the feeding pipe.

[0029] Specifically, after the semicircular pipe 21 is turned over, the lower end of the flow guide plate 26 is in a state of gathering towards the middle, so that the downward flowing molten glass is received by the flow guide plate 26. At the same time, the cooling water on the top contacts the molten glass on the inner side of the flow guide plate 26 and cools it. At this time, the feeding to the elbow pipe can be stopped, the lower end of the feeding pipe can be blocked and unloaded, and then the muffle furnace can be moved away to clean the blockage in the elbow pipe.

[0030] As a preferred embodiment, by setting the plug 24 and the socket 25, the positioning plug is achieved when the two semicircular pipes 21 are close, and the annular pipe structure is formed.

[0031] Specifically, the annular pipe is placed below the molten glass, and is folded to make the molten glass in the middle of the annular pipe, the control switch is opened, the high-pressure cooling air enters from the straight pipe 16, forms the annular cooling air through the vertical hole 22 and the inclined hole 23 on the semicircular pipe 21, and uniformly blows vertically and obliquely upward to the molten glass, so that the molten glass liquid is quickly cooled, the viscosity is increased, and the flowability is effectively reduced.

[0032] Specifically, during normal production, when the flow rate of the molten glass liquid needs to be adjusted, the flow valve 18 is used to adjust the air volume to fine-tune the glass liquid temperature of the feeding pipe, thereby improving the flow stability of the molten glass.

[0033] As Figure 4 In the middle, the lower end of the motor 13 is connected with the sliding seat 132, and the sliding seat 132 is slidingly connected in the guide groove 111 of the bottom plate of the driving box 11, the electro-hydraulic push rod 12 is horizontally fixed on the inner side wall of the driving box 11, and the piston rod end of the electro-hydraulic push rod 12 is connected on the base of the motor 13, the rotating shaft 131 slidingly passes through the inner side wall of the driving box 11, and the outer wall of the rotating shaft 131 slidingly sleeves the guide ring 15, and the lower end of the guide ring 15 is connected with the fixing frame 14, and the fixing frame 14 is welded on the outer wall of the driving box 11.

[0034] Specifically, when the material is blocked, the electro-hydraulic push rod 12 can drive the motor 13, and the rotating shaft 131 drives the semicircular pipe 21 to move outward, and then the motor 13 is started to drive the rotating shaft 131 to rotate, so that the flow guide plate 26 on the semicircular pipe 21 is rotated to the lower side, and then the electro-hydraulic push rod 12 drives the semicircular pipe 21 to be close, and this state is used for the processing process of the molten glass blocked in the pipe.

[0035] The liquid crystal glass feeding pipe rapid cooling adjusting device can effectively solve the problem that the molten glass is difficult to quickly cool and stop flowing in an emergency state, and realize the effect of quickly cooling and stopping the flow of the molten glass in an emergency state on the basis of the existing liquid crystal glass feeding pipe rapid cooling adjusting device technology, and has the effect of conveniently adjusting the flow rate of the molten glass.
