Description

Technical Field

[0001] This utility model relates to the field of substrate glass production technology, and in particular to a device for guiding process water pipe insertion holes in a liquid crystal substrate glass forming furnace. Background Technology

[0002] The existing structure with cooling water pipe 4 inserted in the molding furnace is shown in the attached figure. Figure 1 As shown, when inserting the cooling water pipe 4, the operator needs to first insert the beginning end of the cooling water pipe 4 into the first insertion hole 2, and then push the cooling water pipe 4 horizontally. During the horizontal pushing process, the center of gravity of the cooling water pipe 4 will continuously move closer to the end insertion hole 3. Moreover, the diameter of the insertion hole is larger than the outer diameter of the cooling water pipe 4, so the horizontal pushing process is accompanied by the downward tilt of the cooling water pipe 4. In addition, the diameter of the cooling water pipe 4 is usually 30-40cm, and it is made of metal, so it is quite heavy. Furthermore, during the insertion process, the operator is also subjected to the scorching heat radiating outward from the furnace body. Therefore, the current method of inserting the cooling water pipe 4 is very difficult. In actual operation, it is usually necessary to repeat the operation 2-3 times to insert the cooling water pipe 4 into the end insertion hole 3. Based on this, we propose a device for guiding the process water pipe insertion hole in the liquid crystal substrate glass forming furnace. After installing this device inside the furnace body, it can ensure that the cooling water pipe 4 is inserted into the end insertion hole 3 in one go. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a device for guiding the process water pipe insertion hole in a liquid crystal substrate glass forming furnace.

[0004] This utility model proposes a device for guiding process water pipe insertion holes in a liquid crystal substrate glass forming furnace. The device includes a forming furnace, on one side of which are opened several first-end insertion holes, and on the other side, several end insertion holes corresponding to the first-end insertion holes are opened. The first-end insertion holes and end insertion holes at the same height are connected to a cooling water pipe, the outer diameter of which is smaller than the inner diameter of the first-end insertion holes and end insertion holes. Several guide members corresponding to the end insertion holes are fixed inside the forming furnace. The guide members include a semi-circular arc plate, and both ends of the semi-circular arc plate are connected to flared arc plates extending outward from the top.

[0005] Furthermore, the semi-circular arc plate and the flared arc plate are a single unit, and a transition zone is provided at the connection between the semi-circular arc plate and the flared arc plate.

[0006] Furthermore, the transition area is configured with a rounded chamfer.

[0007] Furthermore, the distance between the top ends of the flared arc-shaped plates gradually increases.

[0008] Furthermore, the distance between the top ends of the flared arc-shaped plates is at least greater than the diameter of the semi-circular arc-shaped plate.

[0009] Furthermore, the upper part of the semi-circular arc plate has an opening, which is connected to the area between the opening and the flared arc plate to facilitate the entry of the cooling water pipe.

[0010] Furthermore, the guide is made of metal and is fixed to the inside of the forming furnace by welding or bolting.

[0011] Furthermore, the center of the semi-circular arc plate is located on the same horizontal straight line as the center of the first and last insertion holes.

[0012] The beneficial effects of this utility model are as follows: By setting a guide with a flared arc plate and a semi-circular arc plate inside the forming furnace, the cooling water pipe that may tilt downwards during insertion can be effectively supported and guided. There is no need for the staff to repeatedly adjust the position and angle of the cooling water pipe. It can be accurately inserted into the end hole in one go, which greatly reduces the difficulty of pipe insertion, significantly improves the installation efficiency of cooling water pipe, and at the same time reduces the working time of the staff in the high temperature environment and reduces the labor intensity.

[0018] Reference Figure 2-4 This utility model proposes a device for guiding process water pipe insertion holes in a liquid crystal substrate glass forming furnace, including a forming furnace 1 (the forming furnace 1 is a supporting equipment for forming liquid crystal substrate glass by the glass melt overflow and downward pulling method, which belongs to the prior art and will not be described in detail here). Several first-end insertion holes 2 are opened on one side of the forming furnace 1, and several second-end insertion holes 3 corresponding to the first-end insertion holes 2 are opened on the other side. Cooling water pipes 4 are inserted into the first-end insertion holes 2 and the second-end insertion holes 3 at the same height. The outer diameter of the cooling water pipes 4 is smaller than the inner diameter of the first-end insertion holes 2 and the second-end insertion holes 3. This part is described as a prior art structure and will not be described in detail here.

[0019] In order to facilitate the insertion of the cooling water pipe 4 from the first end insertion hole 2 into the end insertion hole 3, that is, to achieve the rapid guidance of the cooling water pipe 4, several guide parts 5 corresponding to the end insertion holes 3 are fixed on the inside of the forming furnace 1. The guide parts 5 are made of metal and are firmly fixed on the inside of the forming furnace 1 by welding or bolt connection.

[0020] The guide 5 consists of a semi-circular arc plate 51 and a flared arc plate 52. The upper part of the semi-circular arc plate 51 has an opening that connects with the area between the opening and the flared arc plate 52. This design facilitates the smooth entry of the cooling water pipe 4 into the guide 5. Furthermore, the center of the semi-circular arc plate 51, the first insertion hole 2, and the last insertion hole 3 are located on the same horizontal straight line. This positioning ensures that the cooling water pipe 4 is accurately aligned with the last insertion hole 3 under the guidance of the guide 5, thus improving the accuracy of insertion.

[0021] The flared arc plate 52 is connected to both ends of the semi-circular arc plate 51. Its top end extends outward, and the distance between the top ends of the flared arc plate 52 gradually increases. The distance between the top ends of the flared arc plate 52 is at least greater than the diameter of the semi-circular arc plate 51, which can better play a guiding role. Even if there is a certain deviation when the cooling water pipe 4 is inserted, it can be smoothly introduced.

[0022] The semi-circular arc plate 51 and the flared arc plate 52 are an integral structure. This integrated design enhances the overall strength of the guide 5 and extends its service life. A transition area 53 is provided at the connection between the semi-circular arc plate 51 and the flared arc plate 52. The transition area 53 adopts the form of a rounded chamfer. The rounded chamfer design can prevent the cooling water pipe 4 from getting stuck when entering the semi-circular arc plate 51 from the flared arc plate 52, making the movement of the cooling water pipe 4 smoother.

[0023] During the actual installation of the cooling water pipe 4, the staff inserts the cooling water pipe 4 into the first end insertion hole 2. Due to the outward extension and gradually increasing distance at the top of the flared arc plate 52, it can play a good guiding role for the cooling water pipe 4. Even if there is a certain deviation when the cooling water pipe 4 is inserted, it will be guided to the correct direction by the flared arc plate 52. Subsequently, the cooling water pipe 4 passes through the transition zone 53 and enters the semi-circular arc plate 51. Under the constraint and guidance of the semi-circular arc plate 51, it is accurately aligned with the end insertion hole 3 and smoothly inserted, thus realizing the rapid installation of the cooling water pipe 4 in the water pipe insertion hole in the furnace.

[0024] In summary, by setting up a reasonably structured guide 5, this device effectively solves the alignment problem during the installation of the cooling water pipe 4, significantly improves the installation efficiency of the cooling water pipe 4, and has high practical value.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
