Description

Technical Field

[0001] This invention relates to the field of burners, and more specifically to a protective combustion cylinder assembly for a gas burner. Background Technology

[0002] During burner operation, fuel undergoes intense oxidation and combustion inside the combustion chamber, generating high-temperature flames and flue gas. Due to the enormous heat released by the combustion reaction, the combustion chamber, as the core component directly containing the flame, experiences rapid temperature rise to extremely high levels. However, existing combustion chamber assemblies are typically exposed or only have simple insulation layers. During the heat dissipation phase of equipment operation or immediately after shutdown, the surface temperature of the combustion chamber is extremely high. Due to the lack of effective physical isolation and protection, operators or nearby personnel are highly susceptible to accidental contact during equipment debugging, maintenance, or cleaning, posing a safety hazard. Furthermore, a large amount of heat is directly dissipated into the surrounding environment through the outer wall of the combustion chamber, resulting in significant heat loss, reducing the overall thermal efficiency of the burner, and impacting its energy-saving and environmental performance. Summary of the Invention

[0003] The purpose of this invention is to provide a protective combustion cylinder assembly for a gas burner, which solves the problem of the lack of protective measures in existing combustion cylinders.

[0004] The present invention achieves the above objectives through the following technical solution: a protective combustion cylinder assembly for a gas burner, comprising: a combustion cylinder body and a PLC controller, wherein a protective sleeve is fitted on the outer wall of the combustion cylinder body; The sheath comprises a first component and a second component from the outside to the inside. A first heat exchange chamber is provided between the first component and the second component, and a second heat exchange chamber is provided between the second component and the combustion cylinder body. The first heat exchange chamber is equipped with a temperature detector and is connected to a delivery pump. The PLC controller is used to drive the delivery pump to introduce heat exchange medium into the first heat exchange chamber when the temperature detector detects that the temperature in the first heat exchange chamber is greater than a threshold.

[0005] Preferably, the first kit is provided with a second inlet pipe and a second outlet pipe for communicating with the first heat exchange chamber, and the second inlet pipe is connected to the outlet of the delivery pump.

[0006] Preferably, the second heat exchange chamber is provided with a heat exchange tube, the inlet end of which is connected to the first heat exchange chamber, and the outlet end of which extends to the outside of the first assembly.

[0007] Preferably, the second kit has a communication hole for connecting the heat exchange tube to the first heat exchange chamber, and the second kit has a mounting sleeve for covering the communication hole. A baffle is hinged to the mounting sleeve via a torsion spring shaft, and the baffle is used to block the mounting sleeve.

[0008] Preferably, the top wall of the first kit is connected to a sleeve, a piston is slidably disposed inside the sleeve, a limiting member for restricting the rotation of the baffle is slidably disposed inside the mounting sleeve, and a flexible connecting member is disposed between the limiting member and the piston.

[0009] Preferably, the second outlet pipe is equipped with a solenoid valve, and the PLC controller is used to drive the solenoid valve to close when the temperature detector detects that the temperature inside the first heat exchange chamber is greater than a preset value.

[0010] Preferably, the second assembly has a first inlet pipe and a first outlet pipe extending to the outside of the first assembly and communicating with the second heat exchange chamber. The second heat exchange chamber has an annular plate for cutting off the inner cavity of the second heat exchange chamber and located between the first inlet pipe and the first outlet pipe. The annular plate has a through hole.

[0011] Preferably, there are several through holes, which are arranged in a ring on the annular plate, and the diameter of the through holes gradually increases towards the side away from the first inlet pipe.

[0012] The beneficial effects of this invention are as follows: 1. By covering the outside of the combustion cylinder body with a protective sleeve, direct contact between the staff and the combustion cylinder body is isolated. The protective sleeve is divided into a first kit and a second kit, forming a double-layer physical isolation barrier, which further reduces the intensity of heat diffusion outward, significantly reduces the surface temperature of the outer protective sleeve, avoids burns caused by accidental contact, and significantly improves the safety of burner operation. 2. By using double-layer insulation, the chance of workers being burned is reduced. The first and second heat exchange chambers formed by the inner sides of the first and second kits are used to introduce heat exchange medium to absorb heat and actively absorb the waste heat emitted by the combustion cylinder. This effectively controls the surface temperature of the sheath, realizes the cascade utilization of thermal energy, greatly reduces the unnecessary loss of heat to the environment, and improves the thermal efficiency and energy-saving performance of the burner.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0016] Please see Figure 1 , Figure 2 and Figure 3 A protective combustion cylinder assembly for a gas burner includes: a combustion cylinder body 1 and a PLC controller 11, with a protective sleeve 2 fitted on the outer wall of the combustion cylinder body 1; The sheath 2 includes, from the outside in, a first kit 201 and a second kit 202. Both the first kit 201 and the second kit 202 are made of stainless steel. The outer wall of the first kit 201 is provided with a heat insulation layer. A first heat exchange chamber 203 is provided between the first kit 201 and the second kit 202. A second heat exchange chamber 204 is provided between the second kit 202 and the combustion chamber body 1. A temperature detector 10 is provided in the first heat exchange chamber 203. The first heat exchange chamber 203 is connected to a delivery pump 12.

[0017] It should be noted that when the combustion chamber body 1 is working, the heat exchange medium is introduced into the interior of the second heat exchange chamber 204 to absorb the heat dissipated by the combustion chamber body 1 and reduce the temperature of the outer surface of the sheath 2. The heat exchange medium introduced into the second heat exchange chamber 204 can be a gas (e.g., preheating the air used in the burner). The temperature detector 10 is used to detect the temperature inside the first heat exchange chamber 203 in real time. When the temperature detector 10 detects that the temperature inside the first heat exchange chamber 203 is greater than the threshold, the PLC controller 11 drives the delivery pump 12 to introduce the heat exchange medium into the first heat exchange chamber 203 to absorb the heat inside the first heat exchange chamber 203, reduce the temperature of the outer surface of the sheath 2, avoid unnecessary heat loss, and increase the overall environmental protection and energy-saving performance of the burner.

[0018] In this embodiment, as a further optimization, please refer to... Figure 2 The upper and lower side walls of the first assembly 201 are respectively provided with a second inlet pipe 5 and a second outlet pipe 6. Both the second inlet pipe 5 and the second outlet pipe 6 are connected to the first heat exchange chamber 203. The second inlet pipe 5 is connected to the outlet of the delivery pump 12. The delivery pump 12 introduces the heat exchange medium from the second inlet pipe 5 into the interior of the first heat exchange chamber 203 and then discharges it from the second outlet pipe 6.

[0019] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 3 The inner cavity of the second heat exchange chamber 204 is provided with a heat exchange tube 8. The inlet end of the heat exchange tube 8 is connected to the first heat exchange chamber 203, and the outlet end of the heat exchange tube 8 extends to the outside of the first kit 201. The heat exchange medium that enters the first heat exchange chamber 203 enters the interior of the heat exchange tube 8 and exchanges heat inside the second heat exchange chamber 204, increasing the flow rate of the heat exchange medium flowing inside the second heat exchange chamber 204, increasing the amount of heat exchange medium absorbing heat inside the second heat exchange chamber 204, reducing the amount of heat dissipated from the second heat exchange chamber 204 to the first heat exchange chamber 203, and preventing the surface temperature of the sheath 2 from becoming too high.

[0020] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 3 , Figure 4 and Figure 6The second assembly 202 has a connecting hole 16 on its outer wall, which connects the heat exchange tube 8 to the first heat exchange chamber 203. A mounting sleeve 17 covers the connecting hole 16. A baffle 18 is hinged to the mounting sleeve 17 via a torsion spring shaft 19, sealing the mounting sleeve 17. A sleeve 13 is connected to the top wall of the first assembly 201. A piston 14 slides within the inner cavity of the sleeve 13. A receiving groove is formed on the inner wall of the mounting sleeve 17. A limiting member 20 slides within the inner cavity of the receiving groove. A return spring is provided between the limiting member 20 and the receiving groove. The top wall of the limiting member 20 fits against the bottom wall of the baffle 18 to restrict its rotation. A guide hole is formed on the outer wall of the second assembly 202. A flexible connector 15 (such as a rope, but not limited to a rope) is provided on the piston 14. The end of the flexible connector 15 away from the piston 14 passes through the guide hole and connects to the limiting member 20. The second outlet pipe 6 is equipped with a solenoid valve 7. After the heat exchange medium is introduced into the first heat exchange chamber 203, the temperature detector 10 is still monitoring the temperature inside the first heat exchange chamber 203 in real time. When the detected temperature is greater than the preset value, the PLC controller 11 controls the solenoid valve 7 to close, cutting off the second outlet pipe 6. At this time, the heat exchange medium inside the first heat exchange chamber 203 continues to increase until the piston 14 is pressed and moved upward, pulling the flexible connector 15 and moving the limiting member 20 into the receiving groove, releasing the restriction on the baffle 18. The heat exchange medium inside the first heat exchange chamber 203 applies pressure to the baffle 18, causing it to rotate and open the mounting sleeve 17 and the connecting hole 16, allowing the heat exchange medium inside the first heat exchange chamber 203 to enter the heat exchange tube 8 to absorb the heat inside the second heat exchange chamber 204, increasing the absorption of heat inside the second heat exchange chamber 204 and reducing the amount of heat diffused outward from the second heat exchange chamber 204. Example 2

[0021] As a further optimization of Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The second assembly 202 is provided with a first inlet pipe 3 and a first outlet pipe 4, which are connected to the second heat exchange chamber 204. The ends of the first inlet pipe 3 and the first outlet pipe 4 extend to the outside of the first assembly 201. The second heat exchange chamber 204 is provided with an annular plate 9, which is fitted on the outer wall of the combustion cylinder body 1. The annular plate 9 cuts off the inner cavity of the second heat exchange chamber 204 and divides it into two parts. The annular plate 9 is located between the first inlet pipe 3 and the first outlet pipe 4, and it is provided with a through hole. The heat exchange medium is introduced into the interior of the second heat exchange chamber through the first inlet pipe 3. At this time, the heat exchange medium is located on the right side of the annular plate 9. The heat exchange medium is dispersed by the through hole on the annular plate, so that the heat exchange medium is evenly dispersed after entering the interior of the second heat exchange chamber 204, so that the heat exchange medium can fully absorb heat and reduce the probability of heat loss from the second heat exchange chamber 204 to the outside.

[0022] It should be noted that the first inlet pipe 3 is connected to the equipment that transports the heat exchange medium.

[0023] In this embodiment, as a further optimization, please refer to... Figure 5 There are several through holes, which are arranged in a ring on the annular plate 9. The diameter of the through holes gradually increases towards the side away from the first inlet pipe 3. The heat exchange medium passing through the through holes closer to the first inlet pipe 3 is less than that passing through the through holes farther away from the first inlet pipe 3. This is to make the heat exchange medium pass through the through holes on the annular plate 9 more evenly, so that the heat exchange medium is evenly distributed on the left side of the annular plate 9.

[0024] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
