Description

Technical Field

[0001] The invention relates to the technical field of ever-burning lamps, in particular to an environmentally friendly silicon carbide self-igniting ever-burning lamp. Background Art

[0002] As a key safety component of industrial combustion equipment, the eternal lamp needs to rely on continuous and stable combustion to prevent the risk of explosion. The maintenance of combustion of the eternal lamp depends on the supply of combustible gas, and the multi-gas tank gas supply system is the mainstream technical solution to meet this gas supply demand.

[0003] The existing multi-gas tank gas supply system usually achieves gas source alternation through automatic switching valves, significantly reducing the frequency of manual intervention, and its basic gas supply stability has been recognized by the industry. However, during the gas path switching process, the continuous combustion of the pilot lamp means that gas consumption is always uninterrupted. In other words, the gas supply cavity that is switching the gas path at this time still needs to continue to output gas during the switching transition period to meet the combustion demand. This "exhausted cavity output at the end" state is likely to cause a rapid drop or instability in the gas pressure inside the cavity. This gas pressure disturbance will also be transmitted to the next step, inducing gas flow pulsation, thereby significantly increasing the risk of flame flickering and even destructive flashback.

[0004] Therefore, the existing demand is not met, and we have proposed an environmentally friendly silicon carbide self-igniting ever-burning lamp. Summary of the Invention

This design uses a purely mechanical structure to achieve intelligent self-compensation for air pressure fluctuations, and seamlessly cooperates with the dual-chamber circulating gas supply system to form a dual guarantee of gas supply continuity and pressure stability, significantly improving the combustion reliability of the ever-burning lamp.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] For example 1, please refer to Figures 1-8 Before the user ignites the ever-burning lamp, he needs to perform corresponding gas supply processing on the ever-burning lamp. For this purpose, the present invention sets up an air supply box 1. On the one hand, since the first air storage chamber 101, the second air storage chamber 102 and the third air storage chamber 103 are respectively opened inside the air supply box 1, the first air storage chamber 101 and the third air storage chamber 103 are symmetrically distributed with the second air storage chamber 102 as the center, a blocking block 107 is rotatably provided in the second air storage chamber 102, and the blocking block 107 is fixedly sleeved on one end of the connecting shaft 109, and the other end of the connecting shaft 109 is fixedly connected to the output end of the external motor. A rotating sleeve 108 is provided at the bottom of the first air storage chamber 101 and the third air storage chamber 103, and a spiral slide groove 111 is provided inside the rotating sleeve 108, and a gas pipe 104 is provided inside the rotating sleeve 108. Each gas pipe 1 04, the upper end is respectively connected to the first air storage chamber 101 or the third air storage chamber 103, and the lower end of each air delivery pipe 104 is connected to a replaceable air supply tank. The air delivery pipe 104 is slidably connected to the spiral slide groove 111 through a slider, and the connecting shaft 109 and the outer surfaces of the two rotating sleeves 108 are both sleeved with a connecting gear 105, wherein the connecting gear 105 of the connecting shaft 109 simultaneously engages the two moving racks 106, and each moving rack 106 is respectively engaged with the connecting gear 105 of the corresponding rotating sleeve 108 to form a linkage transmission structure. At the same time, a connecting groove is opened between the first air storage chamber 101 and the second air storage chamber 102, and a seal 110 is slidably arranged inside the connecting groove, and a first spring 112 is arranged between the seal 110 and the inner walls of the first air storage chamber 101 and the third air storage chamber 103.

[0024] In the initial state, the blocking block 107 is located on one side of the connecting groove between the third gas storage chamber 103 and the second gas storage chamber 102, that is, the blocking block 107 will squeeze the seal 110 here, thereby completing the corresponding sealing effect, and the connecting groove between the first gas storage chamber 101 and the second gas storage chamber 102 is in a connected state. It should be noted that a sufficient amount of combustible gas is injected into the first gas storage chamber 101 and the third gas storage chamber 103 in advance, that is, at this time only the gas in the first gas storage chamber 101 can enter the second gas storage chamber 102 through the connecting groove, thereby completing the gas supply effect for the combustion of the eternal lamp.

[0025] When the gas inside the first gas storage chamber 101 is about to run out of gas for supplying to the eternal lamp, the user can start the external motor, thereby driving the connecting shaft 109 and the fixedly connected blocking block 107 to rotate. On the one hand, the rotation of the connecting shaft 109 will drive its connecting gear 105 to rotate synchronously. Since the connecting gear 105 is engaged with two symmetrically arranged moving racks 106 at the same time, and each moving rack 106 is engaged with the connecting gear 105 of the corresponding rotating sleeve 108, the two rotating sleeves 108 are caused to rotate in opposite directions.

[0026] In addition, the spiral groove 111 opened inside the rotating sleeve 108 cooperates with the slider of the air pipe 104, and the top of the air pipe 104 is fixedly connected to the first extrusion plate 113, and the first extrusion plate 113 is limitedly slidably set inside the corresponding cavity. That is to say, after the rotating sleeve 108 rotates, the air pipe 104 and the first extrusion plate 113 fixedly installed on the top will both move axially along the rotating sleeve 108.

[0027] Because the two rotating sleeves 108 rotate in opposite directions, the movement directions of the gas pipes 104 in the first gas storage chamber 101 and the third gas storage chamber 103 are also opposite. When one gas pipe 104 drives the first extrusion plate 113 to move downward, the other gas pipe 104 drives the first extrusion plate 113 to move upward. During this movement, the downward moving gas pipe 104 will drive the gas tank connected to it to move so as to replace the exhausted gas source.

[0028] On the other hand, after the connecting shaft 109 rotates, the blocking block 107 will also rotate synchronously, that is, when the blocking block 107 rotates, the communication groove between the first air storage chamber 101 and the second air storage chamber 102 will be closed due to the movement of the blocking block 107, and the communication groove between the third air storage chamber 103 and the second air storage chamber 102 will also be opened due to the movement of the blocking block 107. It should be noted that the blocking block 107 is a semi-cylindrical structure, that is, when the blocking block 107 contacts the first air storage chamber 101 and the second air storage chamber 102, the connecting groove between the first air storage chamber 101 and the second air storage chamber 102 will be opened. Before the connecting groove between the third gas storage chamber 103 and the second gas storage chamber 102 is opened, the sealing block 107 is still closing the connecting groove between the third gas storage chamber 103 and the second gas storage chamber 102. This arrangement can also ensure to a certain extent that during the process of replacing the gas circuit, there is always gas in the second gas storage chamber 102 for the combustion of the eternal lamp. When the connection between the third gas storage chamber 103 and the second gas storage chamber 102 is opened, the third gas storage chamber 103 can synchronously realize the gas supply effect to the inside of the second gas storage chamber 102, and the preliminary gas circuit replacement can be completed in this way.

[0029] When the gas inside the third gas storage chamber 103 is about to be insufficient for supplying the eternal lamp, the reverse drive connection shaft 109 can reverse the rotation to perform the above-mentioned movement effect, so as to complete the replacement of the gas tank connected to the third gas storage chamber 103, and so on, thereby effectively realizing the dual-source circulation gas supply effect for the eternal lamp.

[0030] Example 2: This example is intended to solve the problem that when the gas circuit is replaced, the gas pressure inside the second gas storage chamber 102 may be unstable, which may cause the burning of the eternal lamp to flash. This example is an improvement based on Example 1. For details, please refer to Figures 1-8 When the gas sources of the first gas storage chamber 101 and the third gas storage chamber 103 are switched, the gas supplied from the first gas storage chamber 101 to the second gas storage chamber 102 may gradually decrease due to the continuous burning of the eternal lamp, which may cause the internal air pressure of the second gas storage chamber 102 to be unstable. Since the ignition component 2 draws gas from the second gas storage chamber 102 to maintain the burning of the eternal lamp, this air pressure fluctuation may cause the flame to flicker, and even pose a safety hazard.

[0031] To address this issue, this solution incorporates a piston block 114 within the second gas storage chamber 102. Upon installation, piston block 114 is pre-filled with a certain amount of combustible gas, the composition of which is identical to that of the gas within the second gas storage chamber 102. The principle is that during the transitional phase of switching gas sources, the rotation of connecting shaft 109 drives cam 126 to rotate, which in turn drives piston block 114 to move. This movement releases the gas pre-stored in piston block 114 into the second gas storage chamber 102, thereby maintaining the stability of the internal pressure.

[0032] In order to realize the pressure stabilizing function when the above-mentioned gas source is switched, the present invention provides a receiving groove 117 below the second gas storage chamber 102, and a cam 126 is installed in the receiving groove 117. The cam 126 can form a transmission connection with the connecting shaft 109 through a one-way bearing. It should be noted that the one-way bearing is an existing technology commonly used by people in this field. The user can specifically select a two-way wedge-type one-way clutch in the one-way bearing for use, or a one-way bearing with the same effect as the two-way wedge-type one-way clutch. It will not be repeated here. That is to say, by using the setting of the one-way bearing, when the connecting shaft 109 rotates, the cam 126 will also be synchronously driven by the connecting shaft 109 to rotate. A moving bar 1 is also slidably provided in the receiving groove 117. 19. A third spring 120 is connected between the moving bar 119 and the inner wall of the receiving groove 117. When the user performs the air path switching operation, thereby driving the connecting shaft 109 to rotate, the cam 126 rotates synchronously therewith. In the initial state, the contour of the cam 126 keeps in contact with the moving bar 119. As the cam 126 rotates, the lifting section of its raised part will squeeze the moving bar 119, overcome the elastic force of the third spring 120, and force the moving bar 119 to produce corresponding displacement in the receiving groove 117. It should be noted that the moving bar 119 slides inside the limiting slide groove opened in the receiving groove 117 through the limiting slider, and this setting can effectively ensure that the moving bar 119 can only move inside the receiving groove 117, and will not be tilted or deflected due to the rotation and squeezing of the cam 126.

[0033] Furthermore, the moving bar 119 is connected to the piston block 114 via the connecting member 123. Specifically, one end of the connecting member 123 is fixed to the moving bar 119, and the other end is fixedly mounted on the piston block 114. Therefore, when the moving bar 119 is displaced under the drive of the cam 126, the connecting member 123 will synchronously drive the piston block 114 to perform corresponding axial movement.

[0034] Since the piston block 114 is movably sleeved on the piston rod 121, and the piston block 114 is stably pressed against the piston rod 121 by the elastic force of the second spring 115, thereby ensuring that its initial position is stable, when the piston block 114 moves axially under the drive of the moving bar 119, its internal structure undergoes a key change: since the second extrusion plate 116 is fixedly sleeved on the piston rod 121, and the second extrusion plate 116 is located in the inner cavity of the piston block 114, the movement of the piston block 114 will drive the second extrusion plate 116 to relatively compress the volume of its inner cavity. , thereby squeezing the combustible gas pre-stored inside. Because the piston block 114 is integrated with a connecting piece 122, the connecting piece 122 includes a connecting pipe and a pressure balance valve. It should be noted that the pressure balance valve is a commonly used and existing technology in this field. Users can adjust it according to actual conditions and their own needs. No further details will be given here. That is to say, when the piston block 114 is not moving, its internal air pressure is stable and balanced with the external pressure. The pressure balance valve is in a closed state, blocking the communication channel between the piston block 114 and the second air storage chamber 102. When the gas in the inner cavity of the piston block 114 is squeezed and the pressure increases, the pre-stored gas will overcome the set pressure of the pressure balance valve and push the valve to open. At this time, the combustible gas in the piston block 114 is gradually released into the second gas storage chamber 102 through the connecting pipe. The key design is that the continuous rotation of the connecting shaft 109 drives the cam 126 to rotate synchronously, and then continuously drives the piston block 114 to move through the moving bar 119 and the connecting piece 123. This process ensures that when the gas source is switched, the gas inside the piston block 114 is continuously and quantitatively pressed into the second gas storage chamber 102 during the entire transition period when the first gas storage chamber 101 and the third gas storage chamber 103 alternately supply gas.

[0035] Through the above-mentioned arrangement, during the brief gap when the gas source switching may cause insufficient gas supply to the second gas storage chamber 102, the pre-stored gas released by the piston block 114 is continuously replenished, thereby maintaining the stability of the internal air pressure of the second gas storage chamber 102. This directly ensures that the gas flow rate drawn from the second gas storage chamber 102 by the ignition component 2 is constant, effectively preventing the flame flickering and flashing of the eternal lamp due to air pressure fluctuations, and significantly reducing the potential safety hazards caused by this.

[0036] When the first gas storage chamber 101 and the third gas storage chamber 103 complete the gas source switching, and the second gas storage chamber 102 is refilled with sufficient combustible gas, the connecting shaft 109 stops rotating. When the connecting shaft 109 stops rotating, since the connecting shaft 109 is connected to the cam 126 through a two-way wedge-type one-way clutch in a one-way bearing, and a reset torsion spring (not shown in the figure) is provided between the cam 126 and the accommodating groove 117, that is to say, when the connecting shaft 109 stops rotating, the cam 126 will gradually return to its initial position under the reset action of the reset torsion spring.

[0037] Before the rotation stops, the design of the cam 126 ensures that the protruding portion thereof is out of contact with the moving bar 119 .

[0038] At this point, the return force of the third spring 120 drives the movable bar 119 back to its original position within the receiving groove 117. The movable bar 119 simultaneously drives the piston block 114 back to its initial position via the connecting member 123. During the return process of the piston block 114, its internal volume gradually increases, forming a negative pressure state. This negative pressure acts on the pressure balance valve on the piston block 114, thereby overcoming its closing force and reopening the communication channel with the second gas storage chamber 102. At this time, the combustible gas in the second gas storage chamber 102 is drawn into the inner cavity of the piston block 114. It should be noted that at this point, the gas path switching is complete, and the gas in the second gas storage chamber 102 is in a full state. Even if the piston block 114 draws some gas during the return process, the resulting slight pressure drop or flow change can be instantly compensated by the first gas storage chamber 101 or the third gas storage chamber 103. Therefore, the total amount of gas in the second gas storage chamber 102 is essentially maintained in a full state, ensuring that the gas supply to the eternal lamp is continuously sufficient and the flame combustion stability is not affected.

[0039] When the piston block 114 is fully reset to its initial position, its interior has been refilled with sufficient combustible gas, and the internal cavity pressure is balanced with the second gas storage cavity 102. The pressure balancing valve automatically resets under the action of the pressure difference disappearing and its own structure such as a spring, restoring the blocking state of the connecting channel.

[0040] With this arrangement, when the gas source of the first gas storage chamber 101 and the third gas storage chamber 103 is switched again, sufficient gas is stored inside the piston block 114, and the aforementioned exhaust and pressure stabilization action can be repeatedly performed to continuously maintain the stability of the gas pressure inside the second gas storage chamber 102, thereby preventing flame flickering and potential dangers.

[0041] When the gas in the third air storage chamber 103 is about to be exhausted, the user can reversely drive the connecting shaft 109 to rotate. Since the connecting shaft 109 and the cam 126 are connected by a two-way wedge-type one-way clutch, the cam 126 will synchronously follow the connecting shaft 109 to rotate in the opposite direction.

[0042] Since two groups of moving bars 119 are symmetrically arranged inside the accommodating groove 117, each moving bar 119 is connected to the piston block 114 through an independent connecting piece 123. When the cam 126 rotates in the opposite direction, the profile of the cam 126 will contact and drive the moving bar 119 on the other side to displace. The moving bar 119 drives the piston block 114 to move through the corresponding connecting piece 123, and the movement of the piston block 114 will again trigger the compression and release process of the pre-stored gas therein. The principle is the same as the forward rotation, thereby continuously replenishing gas to the second gas storage chamber 102.

[0043] When the reverse rotation stops, the cam 126 will also release the drive to the moving bar 119. At this time, the third spring 120 on this side will drive the moving bar 119 and the piston block 114 to reset. During the reset process, the piston block 114 will again absorb gas from the second gas storage chamber 102 to reserve energy for the next operation.

[0044] By driving the connecting shaft 109 forward or reverse, the cam 126 can alternately drive the moving bar 119 components on both sides. This symmetrical design combined with the two-way wedge-type one-way clutch ensures that this solution can not only effectively drive the piston block 114 to perform exhaust and pressure stabilization actions regardless of the rotation direction of the connecting shaft 109, but also after the shaft stops rotating, the corresponding moving bar 119 and piston block 114 can always automatically reset and complete pre-inflation, providing continuous pressure stabilization for subsequent gas source switching.

[0045] In order to prevent the combustible gas in the second gas storage chamber 102 from leaking to the containing groove 117 when the connecting member 123 slides in the movable slide groove 118, this solution sets a dynamic sealing structure composed of a first blocking member 124 and a second blocking member 125 above the movable slide groove 118, and the first blocking member 124 and the second blocking member 125 are fixedly connected to the connecting member 123. When the connecting member 123 is in a stationary state, the retractable first blocking member 124 remains in an extended state under the internal force such as a spring, and its end portion tightly fits the sliding interface of the movable slide groove 118 to form a main sealing barrier, effectively isolating the second gas storage chamber 102 from the containing groove 117. At this time, the second blocking member 125 fixed on the rod of the connecting member 123 is located at the bottom of the second gas storage chamber 102 and maintains a non-contact state with the entrance of the movable slide groove 118. Once the connecting member 123 starts to move, the connecting member 123 will drive the first blocking member 124 to move. When the mounting base of the blocking member 124 moves, the extended portion of the first blocking member 124 will overcome the resistance and gradually retract into the base, releasing the initial blockage. At the same time, the second blocking member 125 fixed on the connecting member 123 moves synchronously with it to the slide groove entrance area, and relies on the precise fit of its outer contour with the slide groove entrance, such as a small gap or elastic seal, to continuously block the gas leakage path during the entire movement of the connecting member 123. When the connecting member 123 moves into place and stops, the extended portion on the first blocking member 124 is completely retracted into the mounting base, and the second blocking member 125 also completely completes the blocking of the part of the movable slide groove 118 that has leaked due to movement, thereby ensuring that the movable slide groove 118 can be reliably blocked regardless of whether the connecting member 123 is stationary or in motion, thereby effectively preventing the gas in the second gas storage chamber 102 from leaking to the receiving groove 117, thereby avoiding the pressure loss or safety hazards that may be caused by this.

[0046] When the gas inside the second gas storage chamber 102 is transported to the inside of the ignition component 2 through the delivery pipe, since the ignition device and the ever-burning lamp are integrated into one inside the ignition component 2, no external igniter is required. It should be noted that the above-mentioned self-ignition integrated equipment is a commonly used and existing technology by people in this field. Users can adjust it according to actual conditions and their own needs. No further details will be given here. That is to say, the above-mentioned equipment can be used to generate a high-voltage arc at the bottom of the ever-burning lamp, thereby igniting the combustible gas inside. After the gas is ignited by the arc, a deflagration flame is formed, and then the main ever-burning lamp is ignited through the ignition hole, thereby achieving the self-ignition effect of the ever-burning lamp.

[0047] And because the material of the fire rod head in the ignition device is made of silicon carbide, this setting not only allows the fire rod head to withstand ultra-high temperature environment, thereby avoiding ablation and deformation, but also due to the high energy conductivity characteristics of silicon carbide, it can also effectively improve the ignition efficiency and ensure that the gas is ignited quickly. At the same time, due to the chemical stability of silicon carbide, it can also resist the corrosive components in the exhaust gas (such as hydrogen sulfide) to a certain extent, extending the service life. This method also improves the burning time and service life of the eternal lamp to a certain extent.

[0048] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
