Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a flow diversion structure for the air intake system of a glass melting furnace. Background Technology

[0002] A glass melting furnace is a thermal equipment used to melt glass raw materials into uniform, bubble-free molten glass that meets quality requirements. It typically consists of a furnace body, a combustion system, a feeding system, and a flue gas system. Air diversion in a glass melting furnace can make the temperature distribution within the furnace more uniform, reduce the temperature gradient in the molten glass, and avoid localized overheating or undercooling. This helps improve glass quality, reduce defects and inhomogeneities, and ensure the performance and appearance of glass products. Air diversion can also be used to regulate the atmosphere within the furnace. By controlling the proportion and distribution of air entering through different inlets, the oxygen supply during combustion can be precisely affected, thereby controlling the degree of combustion and the oxidizing or reducing properties of the atmosphere. Air diversion also helps improve energy efficiency.

[0003] In existing glass melting furnaces, the air is diverted from one inlet to multiple pipes during the air intake process. This diversion method can easily lead to uneven airflow in each pipe, resulting in significant temperature differences within the furnace and consequently, variations in the quality of the processed glass. Therefore, this art proposes a diversion structure for the air intake system of a glass melting furnace to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flow-dividing structure for the air intake system of a glass melting furnace, which aims to improve the problem that in the prior art, the air intake of a glass melting furnace is divided from one air inlet to multiple pipes. This flow-dividing method easily leads to uneven airflow in each pipe, resulting in large differences in temperature inside the furnace and thus differences in the quality of the processed glass.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diversion structure for the air intake system of a glass melting furnace, comprising an air intake pipe, a U-shaped pipe fixedly connected to one end of the air intake pipe, a diversion plate inside the U-shaped pipe, two filter screens installed inside the U-shaped pipe, a waste outlet at the bottom of the U-shaped pipe, two mounting frames fixedly connected inside the U-shaped pipe, a filter screen slidably connected inside the mounting frames, U-shaped pipes fixedly connected to both ends of the U-shaped pipe, a diversion plate inside the U-shaped pipe, and a disassembly assembly on the outside of the mounting frames for quick disassembly of the filter screen.

[0006] Furthermore, the disassembly assembly includes two fixing blocks, the outer side of which is fixedly connected to the outer side of the mounting frame.

[0007] Furthermore, a locking rod is slidably connected to the inner side of the two fixing blocks, and a pull ring is fixedly connected to one end of the locking rod.

[0008] Furthermore, a spring is sleeved on the outside of the locking rod, and a sliding ring is fixedly connected to the outside of the locking rod.

[0009] Furthermore, one end of the spring is fixedly connected to the outer side of the sliding ring, and the other end of the sliding ring is fixedly connected to the outer side of the fixed block.

[0010] Furthermore, the mounting frame is internally slidably connected with a pin, one end of which penetrates the interior of the second filter screen.

[0011] Furthermore, the pin has a locking hole inside.

[0012] Furthermore, the other end of the locking rod engages inside the locking hole.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the air intake pipe contacts the back of the diverter plate one and is evenly divided into two streams, which enter the two channels of the U-shaped pipe one respectively. After passing through the filter screen one, solid impurities can be blocked. Then, after passing through the filter screen two, desulfurization and denitrification treatment is carried out, so that the pure gas is delivered to the port of the U-shaped pipe one, and then divided into two streams by the diverter plate two for delivery. In this way, the gas can be stably and evenly delivered to multiple pipes, avoiding uneven gas distribution in the kiln.

[0015] 2. In this utility model, by opening the waste discharge port, the blocked solid impurities can be discharged from the inside of the U-shaped tube. Pulling the pull ring will pull one end of the locking rod out of the card hole, releasing the lock on the pin. After pulling out the pin, the filter screen can be easily taken out from the inside of the mounting frame. This makes it more convenient to replace the filter screen, and it is more convenient to disassemble and replace it than the traditional bolt fastening. Attached Figure Description

The disassembly assembly is used for quick removal of filter screen 2 7. Air is introduced from one end of the air inlet pipe 1. When the gas reaches the connection between the air inlet pipe 1 and the U-shaped tube 2, it will come into contact with the back of the diverter plate 3 and be evenly divided into two streams. They enter the two channels of the U-shaped tube 2 respectively, and then pass through the filter screen 4 to filter out solid impurities. Then, it passes through the filter screen 2 7 for desulfurization and denitrification treatment, so that the pure gas is delivered to the port of the U-shaped tube 2. It is then divided into two streams by the diverter plate 2 9 for delivery. In this way, the gas can be stably and evenly delivered to multiple pipelines for glass production.

[0024] Reference Figures 2-4The disassembly assembly includes two fixing blocks 10. The outer side of the fixing blocks 10 is fixedly connected to the outer side of the mounting frame 6. The inner side of the two fixing blocks 10 is slidably connected to a locking rod 11. One end of the locking rod 11 is fixedly connected to a pull ring.

A pin 13 is slidably connected inside the mounting frame 6. One end of the pin 13 passes through the inside of the filter screen 7. A locking hole 14 is opened inside the pin 13. The other end of the locking rod 11 is locked inside the locking hole 14. Opening the waste outlet 5 can discharge the blocked solid impurities from the inside of the U-shaped tube 2. Pulling the pull ring will pull one end of the locking rod 11 out of the locking hole 14, releasing the lock on the pin 13. After pulling out the pin 13, the filter screen 7 can be easily removed from the inside of the mounting frame 6, making the replacement of the filter screen 7 more convenient.

[0025] Working principle: First, air is introduced from one end of the intake pipe 1. When the air reaches the connection between the intake pipe 1 and the U-shaped tube 2, it is evenly divided into two streams by the back of the diverter plate 3. The streams enter the two channels of the U-shaped tube 2 respectively, and then pass through the filter screen 4 to filter out solid impurities. Then, it passes through the filter screen 7 for desulfurization and denitrification treatment, so that the pure gas is delivered to the port of the U-shaped tube 2. It is then divided into two streams by the diverter plate 9 for delivery. In this way, the gas can be stably and evenly delivered to multiple pipelines for glass production. In addition, opening the exhaust port 5 can discharge the blocked solid impurities from the inside of the U-shaped tube 2. Pulling the pull ring will pull one end of the locking rod 11 out of the locking hole 14, releasing the lock on the pin 13. After pulling out the pin 13, the filter screen 7 can be easily removed from the inside of the mounting frame 6, making the replacement of the filter screen 7 more convenient.
