Description

Technical Field

[0001] The present invention relates to the technical field of burners, and particularly to a fluid burner with a gas heating function. Background Art

[0002] As an important part of the industrial field, gas fuel engines have attracted much attention due to their low exhaust gas emissions.

[0003] Most traditional natural gas injectors are based on the principle of electromagnetic drive, and their core component is an electromagnet, which drives the opening and closing of the actuator of the natural gas injector through electric energy. Such traditional natural gas injectors are relatively small in size and convenient for installation. However, since most of them use permanent magnets, during continuous injection, the temperature will rise sharply due to continuous long-term power-on. When working in a high-temperature environment, for some permanent magnets such as neodymium iron boron permanent magnets, when the working condition temperature exceeds a certain limit, their magnetism will drop sharply, and this drop is irreversible, resulting in a short service life. Therefore, we propose a fluid burner with a gas heating function. Summary of the Invention

There are two locking parts, and both locking parts are connected to the synchronous rotating part;

[0012] A through hole is provided inside the moving block, and the moving block is slidably sleeved outside the locking rod through the through hole. Two continuous V-shaped grooves are formed on the outside of the locking rod. The guiding part is arranged on the moving block and is connected to the V-shaped groove.

The moving block is slidably sleeved outside the two limiting rods. The connecting part is used to connect the valve core and the connecting block. By means of the provided self-locking mechanism, the function of locking the moving block is realized.

[0013] Furthermore, the synchronous rotating part includes a driving gear, a first driven gear and a second driven gear. The driving gear is fixedly sleeved outside the locking rod, and the driving gear is meshed with the first driven gear and the second driven gear respectively.

[0019] 1. In the structure of the present invention, no dedicated permanent magnet is configured, and a dedicated valve core self-locking mechanism is provided. When the bottom of the valve core is in the open state, disengages from the diversion port, and moves to the upper part of the connection shell, the self-locking mechanism can fix the valve core, thereby solving the problem that the temperature rises sharply due to long-term power-on during the injection duration, and further solving the irreversible drawback of permanent magnet demagnetization, and improving the service life of the valve seat;

[0020] 2. By controlling the three-phase alternating current, the present invention realizes the control of the linear motor relative to the problem that the seating speed of the electromagnet is relatively large.

When the actuator reaches the specified position, the speed is exactly 0 m / s, solving the problem that the seating speed of the electromagnet is relatively large, which is beneficial to further improving the control accuracy;

[0021] 3. The eaves of the discharge port of the valve seat contract inward to form a platform-shaped sealing surface, which ensures that when the valve seat is completely closed, the flame generated by the combustion work inside the burner body will not flash back into the valve seat, improving the safety performance.

Detailed Description of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 , a fluid burner with a gas heating function, including a burner body 1 and a valve seat 2 connected to the gas inlet of the burner body 1. One end of the valve seat 2 close to the burner body 1 is provided with a diversion port 21. A valve core 3 penetrates through the valve seat 2, and a closing block 31 is provided at one end of the valve core 3 close to the diversion port 21. A conical cavity is provided on the valve seat 2. The diversion port 21 is located at the bottom of the conical cavity. The eaves of the diversion port 21 contract inward to form a platform-shaped sealing surface.

[0036] Please refer to Figures 2 to 4 , an air flow heating mechanism 4 is provided inside the valve seat 2, and the air flow heating mechanism 4 is used to uniformly heat the air flow passing through the valve seat 2.

[0037] The valve seat 2 is conical. The air flow heating mechanism 4 includes a heating plate 41 and a diversion plate 42. The heating plate 41 is fixedly installed in a spiral shape inside the conical valve seat 2. In this embodiment, the valve core 3 is located at the center of the spiral heating plate 41. At the same time, the settings of the heating plate 41 and the valve core 3 do not affect each other. An intake pipe is connected to the valve seat 2. The diversion plate 42 is located inside the valve seat 2, and the diversion plate 42 limits and diverts the air flow entering from the intake pipe to the heating plate 41.

[0038] Specifically: through the setting of the spiral heating plate 41, while the gas enters the valve seat 2, the heating plate 41 is heated. Then, under the limiting action of the diversion plate 42, the gas enters the spiral heating plate 41 for flow heating. When the air flow finally flows out from the diversion port 21 of the valve seat 2, the heated gas enters the burner body 1 for rapid combustion, thereby further improving the combustion efficiency of the burner body 1.

[0039] Please refer to Figures 5 to 10 , a diversion closing mechanism 5 is provided outside the valve seat 2. The diversion closing mechanism 5 is used to accurately close the diversion port 21. The diversion closing mechanism 5 includes a heat insulation mechanism 51, a motor driving mechanism 6, a connecting shell 7, and a self-locking mechanism 8. The heat insulation mechanism 51 is installed between the valve seat 2 and the motor driving mechanism 6. The motor driving mechanism 6 is used to drive the valve core 3. The connecting shell 7 is fixedly installed on the side of the motor driving mechanism 6 away from the valve seat 2. The self-locking mechanism 8 is located inside the connecting shell 7, and the self-locking mechanism 8 is used to lock and position the valve core 3.

[0040] In the present invention, for the direct-acting electromagnetic induction gas injection device based on three-phase alternating current, with respect to the problem of relatively large seating speed of the electromagnet, the three-phase alternating current direct-acting electromagnetic actuator can theoretically achieve constant acceleration to improve control accuracy. At the same time, the motor uses a three-phase alternating current linear motor. After three-phase alternating current is introduced into the three-phase windings 62 of the linear motor, a traveling wave magnetic field moving in a straight line direction will be generated, which interacts with the induced current, causing the conductor to be subjected to a force in the direction of the traveling wave magnetic field. This force pushes the conductor and the object connected to the conductor to move in a straight line direction, thereby realizing the driving of the valve core 3 and the opening and closing of the valve seat 2. The motor drive mechanism 6 includes a motor housing 61, windings 62, an insulating sleeve 63, and a mover 64. The motor housing 61 is fixedly installed on the outside of the heat insulation mechanism 51. The windings 62 are fixedly connected to the inner wall of the motor housing 61. The insulating sleeve 63 is arranged between the windings 62 and the mover 64. The valve core 3 fixedly penetrates through the mover 64, and the valve core 3 is slidably connected to both ends of the motor housing 61 through linear bearings respectively.

[0041] Please refer to Figures 7 to 10 , the self-locking mechanism 8 includes a locking rod 81, a synchronous rotating member 82, a locking member 83, a moving block 84, a limiting rod 85, a connecting member 86, and a guiding member 87. The locking rod 81 penetrates through one end of the connecting shell 7 away from the motor housing 61, and the locking rod 81 is rotatably connected to the connecting shell 7 through a one-way bearing. Through the setting of the one-way bearing, the locking rod 81 can only rotate in one direction. The synchronous rotating member 82 is located outside the connecting shell 7, and the synchronous rotating member 82 is connected to the locking rod 81. There are two locking members 83, and both locking members 83 are connected to the synchronous rotating member 82;

[0042] The moving block 84 is internally provided with a through hole, and the moving block 84 is slidably sleeved outside the locking rod 81 through the through hole. Two continuous V-shaped grooves 811 are formed on the outside of the locking rod 81. The guiding member 87 is arranged on the moving block 84, and the guiding member 87 is connected to the V-shaped grooves 811. There are two limiting rods 85, and the two limiting rods 85 are located outside the locking rod 81, and the limiting rods 85 are fixedly installed inside the connecting shell 7. The moving block 84 is slidably sleeved outside the two limiting rods 85. The connecting member 86 is used to connect the valve core 3 and the connecting block.

[0043] Please refer to Figure 6, the synchronous rotating member 82 includes a driving gear 821, a first driven gear 822 and a second driven gear 823. In this embodiment, the first driven gear 822 and the second driven gear 823 have the same model size, and the diameters of the first driven gear 822 and the second driven gear 823 are twice as large as the diameter of the driving gear 821. The driving gear 821 is fixedly sleeved outside the locking rod 81, and the driving gear 821 is respectively meshed and connected with the first driven gear 822 and the second driven gear 823. Rotating shafts 824 are fixedly connected to both the first driven gear 822 and the second driven gear 823. The two rotating shafts 824 respectively penetrate through one end of the connecting shell 7, and the two rotating shafts 824 are both rotatably connected to the connecting shell 7. The end of the rotating shaft 824 located inside the connecting shell 7 is connected to the locking member 83.

[0044] The locking member 83 includes a support shell 831, a crankshaft 832, a support sleeve 833 and a clamping member 9. The support shell 831 is fixedly installed inside the connecting shell 7. One end of the crankshaft 832 is fixedly connected to the rotating shaft 824, and the crankshaft 832 is rotatably connected inside the support shell 831. There are two support sleeves 833, and the two support sleeves 833 communicate with the support shell 831. There are two clamping members 9, and the two clamping members 9 are respectively slidably connected at the support sleeves 833, and the two clamping members 9 are connected to the crankshaft 832.

[0045] The clamping member 9 includes a connecting support rod 91, a support block 92 and a clamping block 93. One end of the connecting support rod 91 is rotatably connected to the crankshaft 832, and the other end of the connecting support rod 91 is rotatably connected to the support block 92 through a connecting seat. The clamping block 93 is fixedly installed on the side of the support block 92 away from the connecting support rod 91, and the side of the clamping block 93 close to the moving block 84 is tapered. At the same time, the top of the clamping block 93 is a clamping surface. A clamping groove 841 is provided on the moving block 84 at the position corresponding to the clamping block 93;

[0046] And in this embodiment, the connection positions of the two connecting support rods 91 of one crankshaft 832 have a certain deviation, that is, when the clamping block 93 of one connecting support rod 91 is clamped with the clamping groove 841, the position where the other clamping block 93 moves along the inside of the support sleeve 833 approaches the deepest position. This kind of setting can ensure that the two clamping blocks 93 at one crankshaft 832 can operate alternately.

[0047] The guiding member 87 includes a guiding rod 871. The guiding rod 871 is fixedly connected to the moving block 84, and one end of the guiding rod 871 is slidably connected to the V-shaped groove 811.

[0048] On both ends of the mover 64 and within the motor housing 61, an upper spring 641 and a lower spring 642 are respectively provided. The upper spring 641 and the lower spring 642 are respectively sleeved outside the valve core 3. In this embodiment, the upper spring 641 and the lower spring 642 are always in a compressed state, and the elastic force effect generated by the upper spring 641 should be greater than the elastic force effect generated by the lower spring 642, so as to fully press the closing block 31 at the bottom of the valve core 3 against the valve seat 2;

[0049] The connecting member 86 includes a top plate 861 and a top rod 862. The top plate 861 is fixedly installed on the top of the valve core 3. There are two top rods 862. The two top rods 862 are fixedly installed on the top plate 861, and the top rod 862 is fixedly installed at the bottom of the moving block 84. Further, through the up and down movement of the valve core 3, the moving block 84 is driven to move through the top plate 861 and the top rod 862;

[0050] Specific implementation process: When the valve seat 2 is opened and gas is introduced into the valve seat 2 at the same time, on the one hand, the spiral heating plate 41 is heated, and on the other hand, after three-phase alternating current is introduced into the three-phase windings 62 of the linear motor, the mover 64 drives the valve core 3 to move, so that the closing block 31 at one end of the valve core 3 is separated from the diversion port 21 of the valve seat 2. At the same time, the other end of the valve core 3 drives the moving block 84 to slide along the locking rod 81 through the top plate 861 and the top rod 862. Due to the limitation of the V-shaped groove 811 on the locking rod 81 and in cooperation with the guide rod 871 on the moving block 84, and because the moving block 84 is synchronously limited by the two limiting rods 85, further the locking rod 81 rotates relative to the connection shell 7;

[0051] When the locking rod 81 rotates, it drives the driving gear 821 to rotate. The driving gear 821 respectively drives the first driven gear 822 and the second driven gear 823 outside it to rotate. In the present invention, the diameter of the driving gear 821 is twice the diameter of the first driven gear 822 and the second driven gear 823. Furthermore, when the first driven gear 822 and the second driven gear 823 rotate, the rotating shaft 824 drives the crankshaft 832 to rotate respectively. When the position where the moving block 84 moves along the locking rod 81 approaches the uppermost position, the crankshaft 832 rotates synchronously, and the connecting support rod 91 at its top drives the clamping block 93 to be clamped into the clamping groove 841 through the support block 92. At this time, the two clamping blocks 93 are respectively clamped and connected to the clamping groove 841, the diversion port 21 of the valve seat 2 is in an open state, and at the same time the three-phase AC linear motor is powered off. Then the two clamping blocks 93 support the valve core 3. At the same time, under the elastic action of the upper spring 641, the connection between the moving block 84 and the clamping block 93 is made more stable;

[0052] At the same time, when it is necessary to close the guide port 21, the linear motor is supplied with three-phase alternating current, and the moving block 84 continues to move up to the top of the locking rod 81. During the upward movement, the accommodating space at the bottom of the clamping groove 841 moves relative to the clamping block 93. When the moving block 84 moves, it drives the locking rod 81 to rotate. At this time, the crankshaft 832 rotates, and the clamping block 93 is disengaged from the clamping groove 841. Subsequently, the moving block 84 moves down until the closing block 31 at the bottom of the valve core 3 closes the guide port 21. The two clamping blocks 93 below are driven by the crankshaft 832 and the connecting support rod 91 to respectively clamp the clamping blocks 93 into the clamping grooves 841. At this time, the three-phase AC linear motor is in a power-off state. At this time, the valve core 3 is clamped by the two clamping blocks 93 and the connection between the upper spring 641 and the lower spring 642, so that the closing block 31 at the bottom of the valve core 3 further closes the guide port 21.

[0053] Until the next time the guide port 21 of the valve seat 2 is opened, the moving block 84 moves upward, and the clamping block 93 is disengaged from the clamping groove 841, and thus reciprocating operation is performed.

[0054] Embodiment 2

[0055] See also Figures 5 to 6 , Embodiment 2 is a further supplementary explanation of Embodiment 1, specifically: the heat insulation mechanism 51 includes a heat insulation shell 511, the heat insulation shell 511 is respectively connected with an inlet pipe 512 and an outlet pipe 513, a heat insulation cavity 514 is provided inside the heat insulation shell 511, and the valve core 3 slides through the heat insulation shell 511, the heat insulation shell 511 is made of heat insulation material, and the heat insulation shell 511 is installed between the motor housing 61 and the valve seat 2;

[0056] Furthermore, in order to prevent the motor housing 61 from being affected by heat radiation, the coolant is introduced into the heat-insulating shell 511 through the inlet pipe 512 and discharged through the outlet pipe 513, thereby achieving the effect of heat insulation on the motor housing 61 and ensuring the operating performance of the winding 62 and the mover 64 inside the motor housing 61.
