Description

Technical Field

[0001] This utility model relates to the technical field of kiln brick processing equipment, and in particular to a lip brick baking device. Background Technology

[0002] Photovoltaic glass lip bricks are a key material in glass forming. Currently, zirconia mullite lip bricks are widely used due to their good thermal shock resistance and corrosion resistance. Since lip brick manufacturers need to perform water grinding and water-cooled cutting after firing, a set of finished lip bricks absorbs about 20 kg of water. When using lip bricks, the temperature rises sharply from room temperature to 1100℃. If there is residual water inside the lip brick, the chance of the lip brick cracking is very high. Severe cracking of the lip brick requires replacement. Therefore, drainage of the pores inside the lip brick is crucial.

[0003] Glass manufacturers typically drain the moisture from the lip bricks by placing them next to the furnace body and allowing them to dry naturally. However, the temperature around the furnace body is usually no higher than 100℃, making it impossible to completely drain the moisture from the pores inside the lip bricks in a short time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a special short kiln for lip bricks, which improves the efficiency of lip brick baking and the quality of dehydration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lip brick baking device, characterized in that it includes a tunnel kiln body, a brick-carrying trolley, and two ground rails located inside the tunnel kiln body. The brick-carrying trolley is slidably connected to the ground rails. The ground rails are hollow tubes with both ends fixed outside the tunnel kiln body. At least one end of the hollow tube is connected to a hot air source. Several exhaust holes located inside the tunnel kiln body are opened on the tube wall of the hollow tube. An exhaust pipe is provided at the kiln top in the middle of the tunnel kiln body.

[0006] Furthermore, the brick-carrying trolley includes a frame and rollers adapted to the ground rail. The rollers are rotatably connected to the frame. The frame includes an upward-opening air outlet and two downward-opening air inlets. The lip brick to be baked is located above the air inlets. Two hollow tubes are located in the two air inlets respectively. The air inlets and the air outlet are connected.

[0007] Furthermore, both ends of the hollow tube are connected to a hot gas source.

[0008] This scheme features a dedicated tunnel kiln for baking lip bricks. Due to its shorter length and slower movement of the brick-carrying trolley within the kiln, a hollow tube is used as a ground rail to improve heat utilization. Hot air is introduced into the kiln through the end of the hollow tube. Furthermore, the structure of the brick-carrying trolley allows the hot air to be centered, preventing it from directly escaping upwards through the gap between the trolley and the side wall of the tunnel kiln, thus improving heat utilization. The dedicated lip brick baking kiln not only improves the baking efficiency of the lip bricks but also avoids dependence on the glass kiln, where the external temperature is significantly affected by the temperature difference between winter and summer, making moisture control of the lip bricks unreliable.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, the baking equipment includes a tunnel kiln 1, a brick-carrying trolley 2, and two ground rails 3 located inside the tunnel kiln 1. The brick-carrying trolley 2 is slidably connected to the ground rails 3. The ground rails 3 are hollow tubes with both ends fixed outside the tunnel kiln 1. At least one end of the hollow tube is connected to a hot air source. Several exhaust holes located inside the tunnel kiln 1 are opened on the tube wall of the hollow tube. An exhaust pipe is provided at the top of the kiln in the middle of the tunnel kiln 1.

[0015] The brick-carrying trolley 2 includes a frame and rollers 4 adapted to the ground rail 3. The rollers 4 are rotatably connected to the frame. The frame includes an upward-opening air outlet 5 and two downward-opening air inlets 6. The lip brick to be baked is located above the air inlets 6. Two hollow pipes are located in the two air inlets 6 respectively, and the air inlets 6 are connected to the air outlet 5. The two ends of the hollow pipes can be connected to a hot air source respectively.

[0016] This scheme sets up a dedicated tunnel kiln for baking lip bricks. Its length is relatively short, and the brick-carrying trolley 2 moves slowly within the kiln. To improve heat utilization, a hollow pipe is used as the ground rail 3, through which hot air is fed into the kiln. Furthermore, the structure of the brick-carrying trolley 2 allows the hot air to be centered, preventing it from directly escaping upwards from the gap between the trolley 2 and the side wall of the tunnel kiln body 1, thus improving heat utilization. It also protects the hollow pipe from slag clogging the exhaust holes. The dedicated lip brick baking kiln improves baking efficiency and avoids dependence on the glass kiln, where the external temperature is significantly affected by winter and summer temperature differences, making moisture control of the lip bricks unreliable.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
