Description

Technical Field

[0001] This utility model belongs to the field of industrial production technology, specifically relating to a precise temperature control and adjustment device for a silicon carbide burner nozzle. Background Technology

[0002] In industrial production, silicon carbide burners are widely used in high-temperature environments such as glass manufacturing, steel smelting, and ceramic firing due to their excellent properties, including high hardness, oxidation resistance, and thermal shock resistance. However, these processes require extremely high precision in temperature control of the burners.

[0003] Patent application CN202322985945.0 proposes a silicon carbide burner nozzle for increasing the flame area. By introducing combustion gas from the nozzle body into the inner and outer nozzle cores, some of the combustion gas is ejected through the jet nozzle a on the inner nozzle core to form a flame, while the remaining combustion gas is ejected through the jet nozzle b and various oblique jet nozzles on the outer nozzle cores to form a flame. This promotes the multi-directional ejection of combustion gas, ensures the diffusion range of combustion gas, increases the overall flame area of ​​the burner nozzle, and is beneficial to improving the flame combustion effect.

[0004] However, the aforementioned silicon carbide burner nozzles cannot achieve high-precision control of gas flow, resulting in significant temperature fluctuations at different nozzle positions. This severely affects the stability of product quality. For example, in glass manufacturing, temperature instability can cause uneven stress within the glass, leading to defects such as bubbles and streaks. Furthermore, the large overall thickness hinders heat dissipation, affecting the normal operation of the nozzle. Utility Model Content

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a precise temperature control and adjustment device for a silicon carbide burner nozzle, comprising:

[0028] The mounting assembly 100 includes a connector 101, a nozzle sleeve 102 fixedly connected to the middle of the connector 101, a lever 103 rotatably mounted at the end of the nozzle sleeve 102, and a collar 104 fixedly connected to the side wall of the end of the lever 103. The collar 104 is rotatably mounted on the side wall of the connector 101, and the lever 103 is in sealing contact with the outer side wall of the through hole in the side wall of the connector 101.

[0029] The adjustment assembly 200 includes a slider 201 slidably mounted inside the connector 101, a rubber plug 202 snapped onto the end of the slider 201, a connecting rod 203 fixedly mounted on the end of the slider 201, and a knob 204 rotatably mounted on the side wall of the end of the connector 101. The knob 204 is inserted into the outside of the end of the connecting rod 203. The side wall of the rubber plug 202 is in sealing contact with the inner side wall of the connector 101, and the rubber plug 202 is inserted above the internal cavity of the connector 101.

[0030] The connector 101 serves as the basic load-bearing component of the entire device, while the nozzle sleeve 102 provides the foundation structure for the burner nozzle installation, ensuring the accuracy and stability of the nozzle installation. A lever 103, equipped with a collar 104, is rotatably mounted on the side wall of the connector 101, and the lever 103 achieves sealed contact with the outer side wall of the through hole in the side wall of the connector 101. This design ensures both flexible rotation of the lever 103 and a tight seal at the connection, preventing gas leakage and facilitating adjustment of the opening size on the side wall of the connector 101. This allows for adjustment of the heat dissipation capacity of the burner nozzle's outer side, adapting to different temperature conditions. A rubber plug 202 is snapped into the end of the sliding member 201. Driven by the sliding member 201, the rubber plug 202 can flexibly control the opening and closing of the internal cavity of the connector 101, thereby adjusting parameters such as the gas flow rate within the device. The connecting rod 203 is fixedly installed at the end of the sliding member 201 and moves synchronously with the sliding member 201. It can guide the sliding member 201 and keep the sliding member 201 moving smoothly. The knob 204 is used to seal the through hole on the side wall of the connector 101. Opening the knob 204 makes it convenient to maintain the rubber stopper 202 and other components.

[0031] Specifically, the adjustment assembly 200 also includes a spring 205 fixedly connected to the inner wall of the connector 101, with the end of the spring 205 inserted into the end of the rubber plug 202.

[0032] When the slider 201 moves, the elastic force of the spring 205 can help the rubber plug 202 better fit the inner wall of the connector 101 to ensure the sealing effect. At the same time, it can prevent the end of the rubber plug 202 from sticking to the inner wall of the connector 101 and causing adsorption, which would prevent the rubber plug 202 from moving.

[0033] Furthermore, the adjustment assembly 200 also includes a top block 206 inserted into the end of the connecting rod 203, the end of the top block 206 being threadedly connected to the inner wall of the knob 204.

[0034] When the knob 204 is rotated, the top block 206 is threadedly connected to the knob 204. The top block 206 will move axially under the drive of the knob 204, thereby pushing the connecting rod 203 and the sliding member 201 to move, so as to achieve precise adjustment of the position of the rubber stopper 202.

[0035] Furthermore, the adjustment assembly 200 also includes a tension spring 207 fixedly connected to the inner wall of the knob 204, with the end of the tension spring 207 inserted into the end side wall of the top block 206.

[0036] When the knob 204 stops rotating, the tension spring 207 can keep the top block 206 and the knob 204 in a relatively stable positional relationship, preventing the knob 204 from losing contact with the top block 206 due to external vibrations or other factors.

[0037] Preferably, the mounting assembly 100 also includes a stop 105 threaded to the end of the nozzle sleeve 102, the stop 105 being snapped into the end of the lever 103.

[0038] The stop block 105 serves to limit the rotation angle range of the lever 103, preventing it from rotating excessively and affecting the stability of the device connection structure.

[0039] It should be noted that the mounting assembly 100 also includes a sealing plug 106 threadedly connected to the middle of the through hole in the side wall of the connector 101, with the end of the sealing plug 106 inserted into the outer side of the cavity in the inner wall of the connector 101.

[0040] Among them, the sealing plug 106 further enhances the sealing performance at the through hole on the side wall of the connector 101, preventing external impurities from entering or internal gas from escaping. Opening the sealing plug 106 facilitates maintenance of the connector 101 and can also assist in heat dissipation, adjusting the heat dissipation capacity of the connector 101.

[0041] Preferably, the mounting assembly 100 further includes a pipe joint 107 threaded to the bottom sidewall of the connector 101, the interior of the pipe joint 107 communicating with the cavity of the inner wall of the connector 101, and the end of the pipe joint 107 being sealed with a plug.

[0042] The pipe connector 107 is threaded onto the bottom side wall of the connector 101, and its interior is interconnected with the inner cavity of the connector 101. It is used to connect to external pipelines to enable the input or output of media such as gas and to regulate the heat dissipation of the burner nozzle. The end of the pipe connector 107 is sealed with a plug to prevent dust and other impurities from entering the pipe connector when it is not necessary to connect to external pipelines.

[0043] When adjusting the temperature of the silicon carbide burner nozzle, the operator rotates knob 204. Since knob 204 is threadedly connected to top block 206, rotating knob 204 causes top block 206 to move axially. Top block 206 pushes connecting rod 203, which in turn causes sliding member 201 to slide inside connector 101. As sliding member 201 moves, the rubber plug 202 at the end of sliding member 201 changes its position above the internal cavity of connector 101, thereby adjusting the ventilation area of ​​the internal cavity. By controlling the ventilation area, the gas flow rate entering the silicon carbide burner nozzle can be precisely adjusted, thus achieving precise control of the burner nozzle temperature. During adjustment, spring 205 always applies elastic force to rubber plug 202, ensuring that rubber plug 202 fits tightly against the inner wall of connector 101, guaranteeing a good sealing effect. Meanwhile, the tension spring 207 stabilizes the top block 206 and the knob 204 after adjustment, preventing accidental rotation of the knob 204 due to vibration or other reasons, which could alter the adjusted parameters. Furthermore, the lever 103 can rotate as needed, with the stop block 105 limiting its rotation angle to adjust the gas injection direction and further optimize the nozzle's performance. The pipe connector 107 can connect to external gas sources and other pipelines. The sealing plug 106 and the collar 104, in seal with the lever 103, ensure the stability of the internal gas environment and reduce the impact of gas leakage on temperature control accuracy.

[0044] In summary, through a series of precisely coordinated components such as knobs, top blocks, connecting rods, and sliding parts, the position of the rubber stopper can be precisely adjusted, thereby accurately controlling the gas flow into the silicon carbide burner nozzle. This achieves precise temperature regulation of the burner nozzle, meeting the needs of various working scenarios with high temperature accuracy requirements. The sealing contact between the rubber stopper and the inner wall of the connector, the sealing contact between the lever and the outer wall of the through hole in the connector, and the sealing of the through hole in the connector by the sealing plug, constitute a multi-layered sealing design that effectively prevents gas leakage, ensures the stability of the internal gas environment of the device, and improves the accuracy and reliability of temperature control. The multi-dimensional adjustment method allows the device to flexibly adjust the working state of the silicon carbide burner nozzle according to different working requirements, improving the device's versatility and adaptability.
