Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology for glass fiber kilns, specifically a heat exchange device for glass fiber kilns. Background Technology

[0002] A glass fiber kiln is a thermal equipment used to produce glass fibers. It is usually constructed of refractory materials and has a specific structure and shape. It can provide a stable high-temperature environment. Generally, the glass raw material needs to be heated to a high temperature of about 1500℃ to melt it. Then, the molten glass is processed into glass fibers through a specific device. The flue gas emitted by the glass fiber kiln during operation contains a large amount of heat. If this heat is not recovered and utilized, it will not only waste energy but may also cause thermal pollution to the environment. Waste heat recovery devices can be installed to transfer the heat in the flue gas to other media, such as air or water, to raise their temperature. These heated media can then be used to preheat the glass raw material, heat combustion air, or generate steam, thereby achieving heat recycling and improving the overall energy utilization rate of the kiln.

[0003] Heat exchange tubes are usually installed inside flue gas ducts. During heat exchange, the heat exchange tubes are exposed to flue gas for extended periods, making their outer surface susceptible to contamination. A layer of fouling forms on the surface, and the thermal conductivity of this fouling layer is much lower than that of the heat exchange tube itself. This effectively adds a thermal resistance between the heat exchange tube and the flue gas, hindering heat transfer. Since the heat exchanger is installed inside the flue gas duct, it is usually in a relatively narrow and inaccessible space, making it difficult for operators to directly contact the heat exchange tube and increasing the difficulty of cleaning. To address this, we propose a heat exchange device for glass fiber kilns. Utility Model Content

[0004] The purpose of this invention is to provide a heat exchange device for a glass fiber kiln to solve the problems mentioned in the background art.

[0015] Preferably, guide rods are slidably passed through the surfaces of both drive plates, and the two guide rods are fixedly connected to the surfaces of pipe A and pipe B, respectively.

[0016] The effect achieved by the above components is that the drive plate slides along the surface of the guide rod as it moves, and the guide rod restricts the movement path of the drive plate, thereby preventing the drive plate from rotating during movement.

[0017] Preferably, one end of the threaded rod is fixedly connected to a turntable, and the vertical cross-section of the turntable is in the shape of a cross.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-2 This utility model provides a technical solution: a heat exchange device for a glass fiber furnace, including a heat exchange structure 1. The heat exchange structure 1 includes pipes A101 and B102 and a heat exchange tube 103. Pipes A101 and B102 are fitted together in a circular tube shape. The heat exchange tube 103 is located inside pipes A101 and B102. Water inlet pipe 104 and water outlet pipe 105 are respectively connected to both ends of the heat exchange tube 103. Both water inlet pipe 104 and water outlet pipe 105 penetrate pipes A101 and B102. A rotating connection is made to the surface of pipe B102. Two arc-shaped plates 106 are fixedly connected to the surface of pipe A101 by four fixing blocks 107. Pins 108 slide through the surface of fixing blocks 107 and are inserted into the surface of arc-shaped plates 106. By setting the heat exchange structure 1, it is easy to disassemble pipe A101 and pipe B102 to clean the heat exchange tube 103. Regular cleaning can remove dirt from the surface of heat exchange tube 103 in time, reduce thermal resistance, make heat transfer smoother, allow the heat exchanger to operate in a high-efficiency state, better recover waste heat in flue gas, and improve energy utilization.

[0031] Reference Figure 2 - Figure 5 As shown in this embodiment: a spring 109 is fitted onto the arc surface of the pin 108. The two ends of the spring 109 are fixedly connected to the pin 108 and the fixing block 107, respectively. The pin 108 is inserted into the arc plate 106 by the force of the spring 109's contraction. The spring 109 improves the stability of the pin 108 within the arc plate 106, thus preventing the pin 108 from dislodging due to shaking. Two circular plates 110 are fixedly connected to the arc surfaces of both the inlet pipe 104 and the outlet pipe 105. The inlet pipe 104 and the outlet pipe 105 cause the circular plates 110 to adhere to the surfaces of pipes A101 and B102, respectively. The circular plates 110 restrict the position of the inlet pipe 104 and the outlet pipe 105, thus preventing them from shaking within pipes A101 and B102. Two grooves 111 are provided on the side of pipe A101 near pipe B102. Two protrusions 112 are fixedly connected to the side of pipe B102 near pipe A101. The size of the protrusions 112 is adapted to the size of the grooves 111. Pipe B102 will drive the protrusions 112 to be inserted into the grooves 111, thereby further improving the airtightness of the fit between pipe A101 and pipe B102.

[0032] Reference Figure 6 As shown, specifically, the surfaces of pipes A101 and B102 are provided with positioning structures 2. Positioning structures 2 include two threaded rods 21, which are rotatably connected to the surfaces of pipes A101 and B102 respectively. A drive plate 22 is threadedly connected to the surface of each threaded rod 21, and a positioning plate 23 is fixedly connected to the surface of each drive plate 22. By setting up positioning structures 2, it is easy to align pipes A101 and B102 with the smoke outlet pipe, thus facilitating their connection and ensuring its airtightness. Guide rods 24 slide through the surfaces of both drive plates 22. The two guide rods 24 are fixedly connected to the surfaces of pipes A101 and B102 respectively. When the drive plate 22 moves, it slides along the surface of the guide rods 24, which restrict the movement path of the drive plate 22, thereby preventing the drive plate 22 from rotating during movement. One end of the threaded rod 21 is fixedly connected to a turntable 25. The vertical cross section of the turntable 25 is in the shape of a cross. The rotation of the turntable 25 will drive the threaded rod 21 to rotate, so that the turntable 25 can facilitate the rotation of the threaded rod 21.

[0033] Working principle: First, place pipes A101 and B102 symmetrically. Then, place heat exchange tube 103 between pipes A101 and B102, so that inlet pipe 104 and outlet pipe 105 are positioned where pipes A101 and B102 are in contact. At this time, inlet pipe 104 and outlet pipe 105 will cause the circular plate 110 to adhere to the surface of pipes A101 and B102, thus restricting the position of inlet pipe 104 and outlet pipe 105. This prevents the inlet pipe 104 and outlet pipe 105 from swaying within pipes A101 and B102. Then, pipes A101 and B102 are brought together, and pipe B102 causes the protrusion 112 to engage with the groove 111, further improving the airtightness of the fit between pipes A101 and B102. Next, the pin 108 is pulled, causing it to move within the fixing block 107. This movement of the pin 108 stretches the spring 109. When the pin 108 moves... After moving it to the appropriate position, rotate the arc plate 106 so that it fits against the surface of pipe A101. Then release the pin 108. The pin 108 will be inserted into the arc plate 106 by the force of the spring 109. The pin 108 restricts the position of the arc plate 106, thereby fixing pipe A101 and pipe B102 together. The spring 109 improves the stability of the pin 108 inserted into the arc plate 106, thus preventing the pin 108 from slipping out of the arc plate 106 due to shaking. The function of removing the 6-channel duct is then implemented, and pipes A101 and B102 are connected to the flue gas outlet pipe of the kiln. At this time, the flue gas discharged from the flue gas outlet pipe will enter pipes A101 and B102. Water inlet pipe 104 and water outlet pipe 105 are both connected to water pipes. At this time, the water in the water pipes will enter the heat exchange tube 103 from the water inlet pipe 104. The heat in the flue gas will heat the water in the heat exchange tube 103, and then the heated water will be discharged from the water outlet pipe 105, thereby exchanging heat with the heat discharged from the kiln.

[0034] When it is necessary to connect pipes A101 and B102 to the flue gas pipe of the kiln, first place the connected pipes A101 and B102 on the surface of the flue gas pipe, then rotate the turntable 25. The rotation of the turntable 25 will drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 will drive the drive plate 22 to move through the thread. The drive plate 22 will slide along the surface of the guide rod 24. The guide rod 24 will limit the movement path of the drive plate 22, thereby preventing the drive plate 22 from rotating during movement. The movement of the drive plate 22 will drive the positioning plate 23 to move closer to pipes A101 and B102. During the movement of the drive plate 22, it will squeeze pipes A101 or B102 until the drive plate 22 is in contact with the surface of the flue gas pipe. At this time, pipes A101 and B102 will be aligned with the pipe opening of the flue gas pipe, thus facilitating their connection.
