Description

Technical Field

[0001] The utility model relates to the field of glass manufacturing, in particular to a tightening device for a material baffle plate of a feeding port of a substrate glass kiln. Background Art

[0002] In the field of flat panel display glass manufacturing, the overflow process technology of TFT substrate glass enjoys a reputation as "high-tech" in the industry due to its high technical barriers, outstanding technical advantages and excellent product performance.

[0003] In order to ensure the high-end and high-quality products, the overflow substrate glass production line uses the most suitable process equipment with stable and reliable performance as much as possible. For example, the kiln feeding equipment uses a spiral feeder, mainly because the spiral feeder has the following technical advantages over other types of feeders: 1. Uninterrupted feeding ensures the continuity and stability of the feeding amount, thereby stabilizing the liquid level and the material mountain. 2. The feeding port remains closed to ensure the stability of the furnace pressure. 3. The feeding flow control accuracy is high, which ensures the stability of the pool furnace temperature. 4. Due to the effect of the spiral rod, the batch material can be further stirred and mixed during the feeding process, which is conducive to the homogenization of the glass.

[0004] like Figure 1 As shown, the barrel 15 at the front end of the spiral feeder 11 is inserted into the countersunk hole of the feed port retaining brick 12, and the feed port retaining brick 12 is embedded in the front wall 16 of the kiln. The front end surface of the barrel 15 fits with the countersunk hole surface of the feed port retaining brick 12. In theory, the contact surfaces that fit each other are required to be tightly fitted. However, in reality, due to the inherent tolerances in the surface processing and installation of equipment and refractory bricks, there is an installation gap between the two contact surfaces. This gap is sufficient to cause the mixed material powder accumulated at the feed port to pass through and cause leakage. Figure 2 This is an enlarged view of the feeding port. As shown in the figure, the dry mixed material powder will leak through the installation gap in area A marked with a red circle.

[0005] Therefore, a Figure 2 The material blocking sealing plate 13 shown blocks the installation gap of the feeding port to prevent the mixed material powder from leaking from here. The material blocking sealing plate 13 is filled with several layers of ceramic fiber blankets 14. The ceramic fiber blankets 14 are resistant to high temperatures and can play the role of flexible sealing gaskets. The material blocking sealing plate 13 and the ceramic fiber blanket 14 are annular, and the inner ring is sleeved on the outer surface of the barrel 15 and keeps a tight fit; the outer side of the ceramic fiber blanket 14 is tightly fitted to the outer side of the feeding port blocking brick 12. However, the material blocking sealing plate 13 may be squeezed and pushed open by the mountain of materials accumulated at the feeding port. Utility Model Content

[0006] In order to prevent a material baffle sealing plate from being squeezed and pushed away by a mountain of material accumulated at a feed port, the present application provides a tightening device for a material baffle plate at a feed port of a substrate glass kiln.

[0007] The present application provides a tightening device for a baffle plate of a substrate glass furnace feeding port, which adopts the following technical solution:

[0009] By adopting the above technical solution, the position of the rear baffle is adjusted by adjusting the assembly so that it is pressed against the material-blocking sealing plate, thereby preventing the material-blocking sealing plate from being squeezed out.

[0010] Optionally, the adjustment assembly includes a top screw, one end of which is threadedly inserted through the front baffle along the axial direction of the barrel and then abuts against the rear baffle.

[0011] By adopting the above technical solution, the top screw is rotated to make it press against the rear baffle plate, thereby driving it to press against the material blocking sealing plate.

[0012] Optionally, a compression nut is provided on the threaded sleeve of the top screw, and the compression nut is fixedly connected with a sleeve, and the sleeve abuts against the material blocking sealing plate.

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] The embodiment of the present application discloses a tightening device for a baffle plate of a substrate glass kiln feeding port, the device is used to reinforce the baffle sealing plate 13 to prevent the baffle sealing plate 13 from being squeezed and pushed away by the material mountain accumulated at the feeding port; the device includes a plurality of front baffles 21, the thickness of the front baffles 21 is preferably 5 mm, and the material is SUS304; the plurality of front baffles 21 are evenly spaced along the circumferential direction of the barrel 15, and in the embodiment of the present application, there are four front baffles 21; each front baffle 21 is slidably connected to a rear baffle 22 along the axial direction of the barrel 15; an adjusting component for driving the rear baffle 22 to slide and abut against the baffle sealing plate 13 is provided on the front baffle 21; the four rear baffles 22 abut against the baffle sealing plate 13 at four corners under the action of the adjusting component, thereby preventing the baffle sealing plate 13 from being squeezed and pushed away by the material mountain accumulated at the feeding port.

[0028] In this embodiment, the adjustment assembly includes a top screw 24, and a nut for the top screw 24 to be threaded is welded to the front baffle 21. One end of the top screw 24 is threaded through the nut and is threadedly connected to a compression nut 23. A gasket 26 is welded to the compression nut 23, and a spring 29 is welded to the gasket 26. A sleeve 25 is welded to the other end of the spring 29, and the sleeve 25 abuts against the rear baffle 22; the compression nut 23 and the gasket 26 are welded together and installed at the front end of the top screw 24 to provide a fulcrum for the compression force of the spring 29. The front end of the spring 29 is welded to the gasket 26, and the rear end is welded to the sleeve. Adjusting the compression nut 23 of the spring 29 will adjust the positions of the spring 29 and the sleeve on the top screw 24 accordingly. The spiral inner diameter of the spring 29 and the inner diameter of the sleeve are slightly larger than the outer thread diameter of the top screw 24. The preferred method is to cut the tail end of the top screw 24 into a cylinder with a smaller outer diameter to ensure that the top screw 24 is not blocked when the spring 29 and the inner cavity of the sleeve move relative to each other. The tail end of the top screw 24 extends into the interior of the sleeve and maintains a distance of 20 to 30 mm from the rear end of the sleeve to ensure that the spring 29 has sufficient compression.

[0029] When in use, adjust the top screw 24 and the spring 29 to compress the nut 23 so that the spring 29 maintains an appropriate compression amount. Then, even if the ceramic fiber blanket 14 softens and shrinks due to heat, the material blocking sealing plate 13 is still subject to the elastic pressure of the top screw 24 and will not be pushed away by the accumulated material.

[0030] The utility model has the following advantages: 1. The adjustment operation area of ​​the tightening device is far away from the feeding port, which reduces the risk of high temperature and live operation of the pool furnace; 2. It avoids the interference of the auxiliary steel structure of the feeding port, and the operation is more convenient; 3. The design of the spring 29 is added to ensure the controllable and continuous tightening force, and prevent the tightening device from loosening due to the softening and deformation of the ceramic fiber blanket 14 due to heat.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
