Description

Technical Field

[0001] This application belongs to the field of thermal vibration elimination burner gas supply technology, specifically a thermal vibration elimination burner gas supply device. Background Technology

[0002] Thermoacoustic vibration elimination burner gas supply device is mainly designed to address the thermoacoustic vibration problem of burners. It utilizes special airflow regulating components and pipeline layout to precisely control the flow rate and pressure of gas and air. During combustion, it optimizes the gas mixture supply characteristics, disrupts the conditions for thermoacoustic vibration formation, and makes the burner operate more smoothly, efficiently, and environmentally friendly.

[0003] As disclosed in CN201852102U, a burner ejector gas supply device includes a chassis and connecting pipes. One end of the connecting pipe is closed, and the other end is connected to the gas outlet of the gas stove valve assembly. The connecting pipes are equipped with gas injection holes. The device is characterized by having three connecting pipes mounted on the same plane of the chassis, with gas injection holes respectively located on each of the three connecting pipes. Each of the three connecting pipes includes two U-shaped pipes and a straight pipe. The two U-shaped pipes are symmetrically arranged on both sides of the straight pipe. Two gas injection holes are located on one side of the U-shaped pipe closest to the straight pipe, and one gas injection hole is located on the other side. One gas injection hole is located on the straight pipe. The chassis has mounting holes, and the connecting pipes are fixed to the chassis by a pressure plate and bolts. The pressure plate has mounting holes, and the bolts pass through these holes on the chassis and the pressure plate. The pressure plate also has through holes corresponding to the positions of the gas injection holes. This invention offers the advantage of providing three combustion conditions: large, medium, and small.

[0004] However, in the case of the gas supply device without a diversion baffle, it is difficult to determine which branch is causing the problem once an abnormal gas supply occurs in the burner system. Because it is impossible to isolate and inspect each branch through simple operations, a comprehensive inspection of the entire gas supply system is required, which consumes a lot of time and effort, resulting in low troubleshooting efficiency and increased equipment downtime. Utility Model Content

[0005] The purpose of this application is to provide a heat-vibration-eliminating burner gas supply device in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A gas supply device for a burner with thermal vibration elimination includes a distributor. A lower screw plate is fixedly connected to the upper surface of the distributor. A rotating column is slidably connected to the inner surface of the distributor. A distributor plate is fixedly connected to the outer surface of the rotating column. An upper screw plate is fixedly connected to the outer surface of the upper end of the rotating column. A rotating handle is fixedly connected to one end of the rotating column relative to the distributor. A plurality of bolts are provided in the through holes opened on the upper surface of the upper screw plate.

[0007] By adopting the above technical solution, when gas diversion is required, the diverter plate can be rotated around the central axis of the rotating column by holding the rotating handle. After rotation, the diverter plate can be fixed by bolts through the through holes on the upper surface of the bolt plate. When a burner or gas supply pipeline in a certain branch malfunctions and requires maintenance, the rotatable diverter plate can be rotated to a position that completely closes off that branch. This cuts off the gas supply to that branch, facilitating safe maintenance of the faulty component by maintenance personnel, while not affecting the normal gas supply to other branches, allowing the entire burner system to operate continuously. In cases where adjustments to the burner layout are required, such as increasing or decreasing the number of burners or changing their positions, the rotatable diverter plate can redistribute the gas according to the new layout requirements.

[0008] In a preferred embodiment, the outer surface of the distributor is provided with a plurality of exhaust pipes.

[0009] By adopting the above technical solution, the exhaust pipe is used to discharge the exhaust gas generated during the combustion process, maintain the pressure balance of the combustion system, and prevent the accumulation of exhaust gas from affecting combustion efficiency and safety.

[0010] In a preferred embodiment, a muffler is fixedly connected to the outer surface of the exhaust pipe, and a safety valve is provided on the distributor through the gas delivery pipe.

[0011] By adopting the above technical solutions, the silencer, through its special internal structure and sound-absorbing materials, effectively reduces the noise generated by gas flow within the pipeline, ensuring that the burner's operating noise meets environmental protection standards and minimizing noise interference to the surrounding environment and personnel. The safety valve opens when the pressure inside the gas supply device exceeds a preset safety threshold, preventing serious safety accidents such as pipeline rupture and explosions caused by overpressure, and ensuring the stable and reliable operation of the device.

[0012] In a preferred embodiment, a buffer tank is fixedly connected to one side of the safety valve via a gas pipeline.

[0013] By adopting the above technical solution, the buffer tank stores a certain amount of mixed gas, which can maintain the stability of gas supply when the gas flow fluctuates, reduce combustion instability caused by changes in gas source, and provide buffer space for subsequent gas pressure stabilization.

[0014] In a preferred embodiment, a pressure sensor is provided on the side of the diverter opposite to the safety valve via a gas delivery pipeline.

[0015] By adopting the above technical solution, the pressure sensor monitors the gas pressure in the gas supply pipeline in real time, converts the pressure signal into an electrical signal and transmits it to the control system, so as to accurately regulate components such as the flow regulating valve and ensure that the gas pressure is within the normal working range.

[0016] In a preferred embodiment, a flow meter base is provided on one side of the pressure sensor relative to the buffer tank via a gas delivery pipe. A flow display meter is fixedly connected to the upper end of the flow meter base, and a flow display meter cover is provided on one side of the flow display meter.

[0017] By adopting the above technical solution, the flow meter base provides a stable installation foundation for the flow display, ensuring the accuracy and reliability of the measurement. The flow display visually presents gas flow data, allowing operators to monitor the gas intake in real time and adjust the flow regulating valve to optimize combustion performance according to combustion requirements. The flow display cover protects the flow display from external factors such as dust and moisture, extending its service life and ensuring stable and normal flow monitoring function.

[0018] In a preferred embodiment, the flow meter base is provided with a flow regulating valve at one end relative to the pressure sensor via an air delivery pipe.

[0019] By adopting the above technical solution, the flow regulating valve accurately controls the flow rate of gas and air, changes the gas flow rate by adjusting the valve opening, and flexibly adjusts the intake air volume according to the burner operating conditions to ensure efficient and stable combustion.

[0020] In a preferred embodiment, the flow regulating valve is fixedly connected to an air inlet pipe on one side relative to the flow meter base.

[0021] By adopting the above technical solution, the air intake pipe introduces the gas and air from the external gas source into the burner gas supply device. Its good sealing and corrosion resistance ensure that the gas is leak-free and smoothly transported, providing a stable supply of raw materials for combustion.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, when gas diversion is required, the diverter plate can be rotated around the central axis of the rotating column by holding the rotating handle. After rotation, the diverter plate can be fixed by bolts passing through the through holes on the upper surface of the bolt plate. When a burner or gas supply pipeline in a certain branch malfunctions and requires maintenance, the rotatable diverter plate can be rotated to a position that completely closes off that branch. This cuts off the gas supply to that branch, facilitating safe maintenance of the faulty component by maintenance personnel, while not affecting the normal gas supply to other branches, allowing the entire burner system to operate continuously. In cases where adjustments to the burner layout are required, such as increasing or decreasing the number of burners or changing their positions, the rotatable diverter plate can redistribute the gas according to the new layout requirements.

An upper screw-hole plate 6 is fixedly connected to the upper outer surface of the rotating column 3. A rotating handle 5 is fixedly connected to one end of the rotating column 3 relative to the distributor 1. Multiple bolts 7 are installed in the through holes on the upper surface of the upper screw-hole plate 6. When it is necessary to divert the gas, the distributor plate 4 can be rotated around the central axis of the rotating column 3 by holding the rotating handle 5. After rotation, the distributor plate can be fixed by the bolts 7 passing through the through holes on the upper surface of the upper screw-hole plate 6. When the burner or gas supply pipeline of a certain branch malfunctions and needs maintenance, the rotatable distributor plate can be rotated to a position that completely closes the branch. This cuts off the gas supply to the branch, making it convenient for maintenance personnel to safely repair the faulty parts, while not affecting the normal gas supply to other branches, allowing the entire burner system to continue operating. In situations where adjustments to the burner layout are required, such as increasing or decreasing the number of burners or changing their positions, the rotatable flow divider can redistribute the gas according to the new layout requirements.

The buffer tank 11 stores a certain amount of mixed gas, which can maintain the stability of gas supply when the gas flow fluctuates, reduce combustion instability caused by changes in the gas source, and provide buffer space for subsequent gas pressure stabilization.

[0036] Reference Figure 1 A pressure sensor 12 is installed on the side of the distributor 1 opposite to the safety valve 10 via a gas supply pipeline. The pressure sensor 12 monitors the gas pressure in the gas supply pipeline in real time, converts the pressure signal into an electrical signal and transmits it to the control system so as to accurately regulate components such as the flow regulating valve 16 and ensure that the gas pressure is within the normal operating range.
