Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to an improved device for an observation window in a molding area. Background Art

[0002] During the overflow down-draw liquid crystal glass manufacturing process, the glass plate is formed by overflow bricks and is pulled down into shape by traction mechanisms such as edge drawing machines and traction rollers. During the production and manufacturing process, the glass may experience abnormal conditions such as dripping due to the influence of the process and equipment status, and glass materials may accumulate in the forming area (that is, in the furnace). Therefore, it is necessary to set an observation window in the forming area to facilitate the observation of the glass flow status. At the same time, the observation window can be opened to clear the glass materials.

[0003] The observation window is usually set at the top of the furnace body. The temperature inside the furnace is relatively high. When users open or close the observation window, there is a risk of burns. At the same time, there will be a certain degree of interference with the molding process and dripping operations. The user opens or closes the observation window through the handle on the outside of the observation window. The moment it is opened, the heat in the furnace will surge up sharply, and the temperature of the furnace mouth will rise instantly. When closing, the handle and the glass window need to be stuck to a certain position before closing, which poses a great risk of burns. At the same time, when the user inspects the furnace, the entire observation window needs to be opened, and a lot of heat is lost in the furnace, affecting the quality of the products in the furnace. In addition, if the observation window is damaged, the entire window needs to be removed, and the machine needs to be shut down for replacement, which may cause unnecessary losses. There is also a risk of broken plates and blockages during replacement. Utility Model Content

[0004] The purpose of the utility model is to provide an improved device for an observation window of a molding area to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An improved device for an observation window in a molding area comprises a furnace body, a cover plate is integrally formed on the top of the furnace body, a mounting groove is formed through the top of the cover plate, a window frame is fixed in the mounting groove, a crossbeam is integrally formed inside the window frame, and the window frame is divided into two upper and lower cavities by the crossbeam inside the window frame, a first opening is provided in the upper cavity of the window frame, and a first glass is fixed in the first opening;

[0007] A second opening is provided in the lower cavity of the window frame, a glass door is rotatably connected to a side of the window frame top corresponding to the second opening, a square groove is provided on the inner wall of the window frame corresponding to the outer periphery of the second opening, the glass door comprises a door frame, a second glass is embedded and fixed to a side of the door frame body corresponding to the second opening, the shape of the second glass is matched with the shape of the second opening, a guide plate is fixed to a side of the door frame bottom corresponding to the square groove, and the guide plate is used in conjunction with the square groove.

[0008] As a further solution of the utility model: the guide plate includes a frame-shaped vertical extension portion, the vertical extension portion is fixed to the bottom of the door frame, and the bottom end of the vertical extension portion extends horizontally outward to form a horizontal extension portion, and the vertical extension portion is integrally formed with the horizontal extension portion.

[0009] As a further solution of the utility model: the sum of the height of the vertical extension part and the height of the horizontal extension part is greater than or equal to the height inside the square groove, and the sum of the width of the vertical extension part and the width of the horizontal extension part is less than or equal to the width inside the square groove.

[0010] As a further solution of the present invention: the connection between the vertical extension portion and the horizontal extension portion is designed to be rounded.

[0011] As a further solution of the utility model: a plurality of screw holes are arranged on the inner wall of the window frame corresponding to the outer side of the square groove, and bolts are arranged on one side of the door frame body corresponding to the plurality of screw holes, and the bolts are used in conjunction with the screw holes.

[0012] As a further solution of the utility model: hinges are provided at both ends of one side of the door frame, and the door frame is rotatably connected to the cover plate through the two hinges.

[0013] As a further solution of the utility model: a handle is fixed on a side of the door frame away from the hinge, and a heat insulation sleeve is provided on the handle.

[0014] As a further solution of the utility model: a sealing strip is fixed to the outer periphery of the bottom of the door frame corresponding to the square groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the utility model, the observation window is a split design. The working conditions inside the furnace body can be observed through the first glass and the second glass. When the furnace body needs to be inspected and repaired, only the lower glass door (that is, the second glass) needs to be opened, and the second opening is opened. The first glass is still fixed. At this time, the contact area between the inside and the outside of the furnace body is smaller, and the heat loss in the furnace is less, which has less impact on the processed products in the furnace. At the same time, the glass door is only connected to the cover plate through a hinge, and the glass door is not in direct contact with the window frame. When the glass door is damaged and needs to be replaced, the hinge can be unscrewed to remove the glass door. During the disassembly process, the glass door will not be squeezed with the window frame, and the window frame will not be damaged, thereby reducing the risk of maintenance;

[0017] 2. In the utility model, the heat inside the furnace body is dissipated from bottom to top. After passing through the guide plate, the heat is dissipated horizontally to the surroundings along the horizontal extension of the bottom end of the guide plate. When the user needs to close the glass door, as the glass door slowly falls, the heat inside the furnace body is no longer directly transferred from bottom to top, but from bottom to top and then to the left, right, front and back, and at the same time dissipated in four directions of the front, back, left and right of the glass door. At this time, the handle held by the user is not easy to gather too much heat, and the hand will not be burned by the high temperature inside the furnace body. At the same time, a heat insulation sleeve is arranged on the handle to insulate and further prevent high temperature burns;

[0018] 3. In the utility model, when the glass door is closed, the guide plate will be placed in the square groove. The guide plate and the square groove are used together to separate the inside of the furnace from the outside, block the heat inside the furnace, and prevent heat loss. At the same time, a sealing strip is arranged at the bottom of the door frame to further insulate and prevent the heat in the furnace from flowing out from the gap between the glass door and the window frame, so that the insulation effect is better.

[0019] 4. In the utility model, when the glass door is closed, the bolt can be screwed into the screw hole to fix the glass door on the furnace body, so as to prevent the glass door from being opened at will and reduce potential safety hazards. When the glass door needs to be opened, the bolt can be screwed in the opposite direction to separate the glass door from the furnace body, making the use of the glass door safer and more convenient.

[0020] 5. In the utility model, the height and width of the guide plate can be designed accordingly as needed. When the overall height of the guide plate is the same as the groove height of the square groove, the guide plate is just inserted into the square groove to prevent heat loss. When the overall height of the guide plate is greater than the groove height of the square groove, the upper end of the guide plate is higher than the square groove, which can also prevent heat loss. At the same time, as long as the width of the bottom end of the guide plate is not greater than the groove width in the square groove, the guide plate can be normally inserted into the square groove. The longer the bottom end of the guide plate is, the better the overall support stability is, and the better the ability to isolate heat is. BRIEF DESCRIPTION OF THE DRAWINGS

The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0029] Example 1

[0030] See also Figures 1-2In an embodiment of the utility model, an improved device for an observation window in a molding area includes a furnace body 1, a cover plate 2 is integrally formed on the top of the furnace body 1, a mounting groove 5 is penetrated through the top of the cover plate 2, a window frame 3 is fixed in the mounting groove 5, a crossbeam is integrally formed inside the window frame 3, and the window frame 3 is divided into two upper and lower cavities by the crossbeam inside the window frame 3, a first opening 6 is arranged in the upper cavity of the window frame 3, a first glass 7 is fixed in the first opening 6, and the working condition inside the furnace body 1 can be observed through the first glass 7, a second opening 8 is arranged in the lower cavity of the window frame 3, a glass door 4 is rotatably connected to one side of the top of the window frame 3 corresponding to the second opening 8, a square groove 9 is arranged on the outer periphery of the inner wall of the window frame 3 corresponding to the second opening 8, and a plurality of screw holes 10 are arranged on the outer side of the inner wall of the window frame 3 corresponding to the square groove 9.

[0031] See also Figure 3 The glass door 4 includes a door frame 41. A second glass 42 is embedded and fixed on one side of the door frame 41 corresponding to the second opening 8. The shape of the second glass 42 matches the shape of the second opening 8. When the glass door 4 is closed, the second glass 42 can be snapped into the second opening 8. Both ends of one side of the door frame 41 are provided with hinges 43, and the door frame 41 is rotatably connected to the cover plate 2 through the two hinges 43. When the glass door 4 is damaged and needs to be replaced, the hinges can be unscrewed to remove the glass door. During the disassembly process, the glass door only contacts the cover plate and will not be squeezed with the window frame 3, so the window frame will not be damaged, thereby reducing the maintenance risk.

[0032] A handle 44 is fixed to the side of the door frame 41 away from the hinge 43, and an insulating sleeve 45 is arranged on the handle 44. The glass door can be opened by pulling the handle 44. The insulating sleeve 45 on the handle can insulate and prevent high temperature burns. Bolts 46 are arranged on one side of the door frame 41 corresponding to the multiple screw holes 10. The bolts 46 are used in conjunction with the screw holes 10. When the glass door is closed, the bolts 46 are turned to tighten them into the screw holes 10 to fix the glass door to the furnace body, thereby preventing the glass door from being opened at will and reducing safety hazards. When the glass door needs to be opened, the bolts can be turned in the opposite direction to separate the glass door from the furnace body.

[0033] Example 2

[0034] See also Figure 4 On the basis of Example 1, a guide plate 48 is fixed to one side of the bottom of the door frame 41 corresponding to the square groove 9. The guide plate 48 is used in conjunction with the square groove 9. When the glass door is closed, the guide plate 48 will be placed in the square groove 9. A sealing strip 47 is fixed to the outer periphery of the bottom of the door frame 41 corresponding to the square groove 9. The sealing strip 47 is used for heat insulation and sealing. When the glass door is closed, the sealing strip 47 blocks the four sides of the square groove 9 to prevent the heat in the furnace body from flowing out from the gap between the glass door and the window frame, thereby keeping the inside of the furnace body warm.

[0035] The deflector 48 includes a frame-shaped vertical extension portion 481, which is fixed to the bottom of the door frame 41, and the bottom end of the vertical extension portion 481 extends horizontally outward to form a horizontal extension portion 482, and the vertical extension portion 481 and the horizontal extension portion 482 are integrally formed, and the sum of the height of the vertical extension portion 481 and the height of the horizontal extension portion 482 is greater than or equal to the height of the square groove 9, and the sum of the width of the vertical extension portion 481 and the width of the horizontal extension portion 482 is less than or equal to the width of the square groove 9. Width, when the overall height of the guide plate 48 is the same as the groove height of the square groove 9, the guide plate just fits into the square groove, which can prevent heat loss. When the overall height of the guide plate 48 is greater than the groove height of the square groove 9, the upper end of the guide plate is higher than the square groove, which can also prevent heat loss. As long as the width of the bottom end of the guide plate 48 is not greater than the groove width in the square groove 9, the guide plate can be normally inserted into the square groove. The longer the bottom end of the guide plate 48 is, the better the overall support stability is, and the better the ability to isolate heat is.

[0036] See also Figure 5 The heat inside the furnace body 1 dissipates from bottom to top, and after passing through the guide plate 48, the heat dissipates horizontally to the surrounding areas along the horizontal extension portion 482 at the bottom of the guide plate 48. When the user needs to close the glass door 4, as the glass door slowly falls, the heat in the furnace body is no longer directly transferred from bottom to top, but from bottom to top and then to the left, right, front and back, and at the same time dissipates in the front, back, left and right directions of the glass door. At this time, it is not easy for the user to gather too much heat at the handle 44 held by the user, and the hand will not be scalded by the high temperature in the furnace body. In order to ensure smoother heat dissipation, the connection between the vertical extension portion 481 and the horizontal extension portion 482 is designed to be rounded. At this time, the resistance to heat flow is reduced. When the glass door is closed, it is less likely for heat to accumulate at the door frame 41, further reducing the risk of scalding.
