Abstract
Description
Technical Field
[0001] This invention relates to the field of glass production equipment adjustment, specifically to a method and apparatus for adjusting the brick joints of a glass kiln. Background Technology
[0002] Glass kilns should possess excellent sealing performance. Theoretically, the smaller the joints between refractory bricks, the better. However, in practice, due to the thermal expansion and contraction properties of refractory bricks, certain joints are always left during construction to prevent the bricks from cracking due to expansion and compression during firing. At the end of firing, it is always desirable for the joints to close perfectly. However, due to the shrinkage of fused AZS bricks, larger joints may appear in certain areas (such as flow channels or pool walls). Larger joints exacerbate the erosion of the refractory bricks by the flame or molten glass, affecting both glass quality and kiln life. Controlling the size of these joints is a problem that needs to be solved in current production processes. Summary of the Invention
[0003] The present invention aims to overcome the shortcomings of the prior art by providing a method and apparatus for adjusting the brick joints of a glass kiln.

[0006] Depending on the usage of the glass kiln, use tools to rotate the locking nut or adjusting nut in the brick joint adjustment device of the glass kiln to adjust the tension between two refractory bricks, thereby adjusting the gap between the splicing joints of two adjacent refractory bricks.
[0007] A device used in a method for adjusting the joint of bricks in a glass kiln is characterized in that: it includes a base plate, a set of first pull rods connected to the base plate, a second bent portion corresponding to the kiln bricks provided at one end of the first pull rods, a sliding pull rod passing through the base plate, a threaded section provided at one end of the sliding pull rod, an adjusting nut corresponding to the threaded section, a spring corresponding to the adjusting nut and the base plate sleeved on the body of the sliding pull rod between the adjusting nut and the base plate, and a first bent portion corresponding to another kiln bricks provided at the other end of the sliding pull rod.
[0008] Based on the above technical solutions, the following further technical solutions are also possible:
[0009] The set of first tie rods consists of two rods, with a sliding tie rod passing through the base plate between the two first tie rods.
[0010] The first pull rod includes a coaxially distributed smooth rod section and a second threaded section. The second bent part is located at one end of the smooth rod section, and a locking nut corresponding to the substrate is provided on the second threaded section.

[0014] Advantages of the invention:
[0015] This invention has a simple structure and is easy to use. It can effectively adjust the size of the brick joints caused by the expansion and contraction of the refractory bricks in the kiln, reduce the erosion of the refractory bricks by the molten glass, extend the service life of the furnace, and reduce the production costs of glass enterprises.

[0018] Figure 3 yes Figure 1 A schematic diagram of the structure of the first tie rod. Detailed Implementation
[0019] like Figure 1-3 As shown, an adjusting device for adjusting the joints of bricks in a glass kiln includes a rectangular base plate 1, with a sliding rod 3 passing through the center of the base plate 1. One end of the sliding rod 3 is a threaded section, on which a corresponding adjusting nut 4 is provided.
[0020] A spring 5 is fitted onto the sliding rod 3 between the adjusting nut 4 and the base plate 1. One end of the spring 5 contacts one side surface of the base plate, and the other end contacts the end face of the adjusting nut 4. The force of the spring's extension and retraction is adjusted by rotating the adjusting nut.
[0021] Except for the threaded section, the sliding rod 3 has a smooth rod body. A first bend 3a extends from the end of the smooth rod. The first bend 3a and the smooth rod form a rounded transition. The first bend 3a and the smooth rod are distributed at right angles.
[0022] A shorter first pull rod 2 is respectively installed on the base plate 1 on both sides of the sliding pull rod 3, and the first pull rod 2 is parallel to the sliding pull rod 3. The first pull rod 2 includes a smooth rod section a and a threaded section b coaxially distributed. The second bent part 2a is located at one end of the smooth rod section, and a locking nut 2b corresponding to the base plate 1 is provided on the second threaded section.
[0023] The second bend 2a and the optical rod form a rounded transition, and the second bend 2a and the optical rod are distributed at right angles. The second bend 2a and the first bend 3a are located on the left and right sides of the substrate 1. The second bend 2a and the first bend 3a have the same length.
[0024] The threaded section and the rod body of the sliding tie rod 3 are longer than the corresponding lengths of the second threaded section b and the smooth section a in the first tie rod 2.
[0025] A method for adjusting the joints of bricks in a glass kiln, comprising the following steps:
[0026] Blind holes corresponding to the second bend 2a and the first bend 3a are provided on the bricks on both sides of the joint between two adjacent refractory bricks 6 in the glass furnace, so that the second bend 2a and the first bend 3a can be inserted accordingly. Then, depending on the use of the glass furnace, the locking nut or adjusting nut is turned with a tool to adjust the distance between the base plate and the adjusting nut, thereby adjusting the spring force and controlling the tension between the second bend 2a and the first bend 3a, thus adjusting the gap between the joint between the two adjacent refractory bricks.
[0027] The blind hole is located between 75±20mm from the splice seam.
[0028] Depending on the size of the refractory bricks, multiple devices for adjusting the brick joints of the glass kiln provided by this invention can be selected to connect two refractory bricks. However, when in use, the installation directions of two adjacent devices are opposite, thereby ensuring the uniformity of the tension provided by the two devices.
