Description

Self-dust removal multi-ignition point co-heating fuel heater Technical Field

[0001] The invention belongs to the technical field of automobile accessories, in particular to a self-dust-removing multi-ignition-point co-heating fuel heater. Background Art

[0002] A fuel heater is a small heating device that burns liquid fuels such as diesel, gasoline, natural gas, and currently available bio-oil. The fuel is mechanically separated and forms an oil film using the material density of the mechanism. After being mixed with combustion air and atomized, it is ignited by an ignition component, releasing a large amount of combustion heat. The fuel heater's structure and connections include a motor, combustion fan, oil feeder, volatilization screen, ignition plug, combustion chamber, and heat exchanger.

[0003] The current domestic and international fuel heater market offers a diverse range of products, all with similar structures and performance. Market application research has revealed the following issues: Current heaters are limited in their operating environments. In coal mines, mining operations, and dusty environments, both domestic and international heaters experience issues such as ignition failure or low combustion efficiency. Furthermore, the heater motor life is significantly reduced, noise levels increase, and exhaust gas composition fails to meet environmental standards. Heavy carbon deposits in the combustion chamber, burn-through, and deformation can occur, rendering the heaters ineffective.

[0004] Therefore, a fuel heater that can solve the above problems is needed. Summary of the Invention

[0005] In response to the above problems, the present invention provides a self-dust removal multi-ignition point co-heating fuel heater, which is used to solve the problems of lack of heater ignition function and misfire during combustion, temporary carbonization in the combustion chamber cavity, and low fuel heat conversion efficiency in dusty environments.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a self-dusting multi-ignition point co-heating fuel oil heater, comprising a combustion chamber, wherein the outer side of the combustion chamber is provided with a plurality of first air inlets which are connected inside and outside;

[0007] An ignition plate is fixedly provided on the combustion chamber near the air inlet end, a volatilization chamber is provided in the ignition plate, one side of the volatilization chamber is connected to a feed pipe, and an igniter is also provided in the ignition plate;

[0008] A plurality of second air inlets connected to the interior of the combustion chamber are provided on the end surface of the ignition disk. The second air inlets are arranged in an array around the circumference of the volatilization chamber. A movable pin which can be inserted into the second air inlet to clean the second air inlet is movably provided on the air inlet side of the ignition disk. The movable pin is connected to a driving assembly that drives its movement.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up multiple second air inlets, air can be easily introduced into the combustion chamber from multiple points, thereby dispersing the air intake. In a dusty environment or when the air quality is severely polluted, air supply ignition and combustion can still be achieved, thereby reducing the probability of single-cavity misfire. The provided movable pin can clean the hole wall of the second air inlet. When dust blocks the second air inlet, the air intake of the second air inlet is still kept unobstructed through the penetration of the movable pin. The heater can still ensure the importance of mixing the volatile density of the oil with the air in a dusty environment, and reduce the influence of the dense air containing dust on combustion and carbide formation. Under normal use, there will be no misfire.

[0010] As a further improvement of the above scheme, a guide member protruding outward is provided on the outer end face of the ignition disk, and a push head is slidably provided on the guide member to press the movable pin. The push head is threadedly connected to the main shaft, and the main shaft is dynamically connected to the drive assembly.

[0011] As a further improvement of the above solution, a connecting plate is provided between the several movable pins, the connecting plate and the ignition disk are slidingly arranged with respect to each other, and a spring is provided between the connecting plate and the ignition disk, and the spring presses the connecting plate to enable the movable pin to slide out of the second air inlet.

[0012] The technical effect of the above improvement is: through the set push head, it can be driven to move toward the side of the connecting plate when the main shaft rotates. After contacting the connecting plate, it will push the connecting plate and the movable pin to move synchronously, so as to prompt the movable pin to enter the second air inlet, thereby cleaning the second air inlet to facilitate normal combustion in the combustion chamber. The set spring has a reverse pushing effect on the connecting plate, and can push the movable pin out from the second air inlet when the push head loses its pushing force on the connecting plate in the reverse movement, so that the second air inlet can take in air.

[0013] As a further improvement of the above scheme, a first ring is rotatably sleeved on the outer side of the combustion chamber, and the first ring is provided with a plurality of first extension rods extending along its axial direction. The first extension rod is provided with a plurality of cleaning parts that can be extended into the first air inlet. The cleaning part is specifically a part extending from the first extension rod. When the cleaning part moves in the first air inlet, the first air inlet is cleaned.

[0014] The technical effect of the above improvement is that when the first ring rotates on the combustion chamber, it can synchronously drive the cleaning member to slide in the first air inlet, thereby cleaning the dust attached to the wall of the first air inlet hole and ensuring normal air intake.

[0015] As a further improvement of the above solution, a movable ring is sleeved on the main shaft, one end of the movable ring is provided with a protruding second extension rod, and the end of the second extension rod is provided with a guide pin protruding outward;

[0016] A rotating member is fixed on the outer side of the first ferrule, and the rotating member has a first guide portion that can slide relative to the guide pin;

[0017] A reset member for pulling the rotating member back is also provided between the rotating member and the combustion chamber.

[0018] As a further improvement to the above solution, a first toggle member is fixedly provided on the main shaft and arranged along the diameter direction thereof, and a second toggle member is provided on the end surface of the movable ring so as to be in contact with and movable with the first toggle member;

[0019] The first guide portion is arranged obliquely.

[0020] The technical effect of the above improvement is: through the toggling action of the first toggle member on the second toggle member, the movable ring can be driven to rotate together, and under the drive of the second extension rod and the main shaft, the rotating member can be synchronously driven to rotate together, and when the rotating member rotates, the first ring can be driven to rotate together, so that the cleaning member can be driven to rotate into the first air inlet, thereby cleaning the first air inlet. However, when the rotating member rotates to the extreme position, it will not rotate. Under the guidance of the first guide part, the guide pin slides in the first guide part. At this time, the movable ring will rotate away from the first toggle member under the toggle of the first toggle member until the first toggle member is The movable member no longer has an actuating effect on the second actuating member. At this time, under the pull of the reset member, the rotating member and the first ring rotate in the opposite direction to reset, and the cleaning member can slide out of the first air inlet. Therefore, when the movable pin is pushed to clean the second air inlet, the first air inlet can also be cleaned synchronously. However, under the pull of the reset member, the cleaning member quickly withdraws from the first air inlet, thereby avoiding the situation where the first air inlet and the second air inlet are blocked at the same time, and air cannot be taken in and combustion cannot be carried out internally. When the main shaft rotates in the opposite direction, the push head can be driven to push the movable ring to move toward the side of the first actuating member until the first actuating member can contact the second actuating member.

[0021] As a further improvement to the above solution, an inner lining ring is rotatably arranged on the outer periphery of the rotating member, a plurality of penetrating second guide portions are further provided on the rotating member, and a plurality of limit pins that can move relative to each other in the second guide portions are provided on the inner lining ring;

[0022] An outer shell is fixedly arranged on the outer circumference of the inner liner ring. The outer shell and the combustion chamber are fixed to each other and completely cover the first air inlet.

[0023] The technical effect of the above-mentioned improvement is: the outer shell is mainly set to isolate the intake air so that the air can completely enter the interior of the combustion chamber through the first air inlet or the second air inlet. The inner liner is mainly used to support the rotation of the rotating part. At the same time, under the interaction of the limit pin and the second guide part, the rotation angle of the rotating part can be limited to avoid the rotating range of the rotating part being too large.

[0024] As a further improvement to the above solution, a plurality of volatilization nets are provided on the circumferential side wall of the volatilization chamber, and the positions of the volatilization nets and the second air inlet correspond to each other;

[0025] The combustion chamber is arranged tangentially along the diameter of the combustion chamber. A scraper is fixedly provided on the end of the cleaning piece, and the scraper protrudes outward along the tangential direction of the cleaning piece.

[0026] The technical effect of the above improvement is that by arranging a volatilization net on the outside of the volatilization chamber corresponding to the position of the second air inlet, the atomized fuel can be mixed with the air first when it is sprayed out, and the combustion is more complete, thereby avoiding the formation of carbon deposits;

[0027] The tangential combustion chamber can facilitate the formation of a cyclone when the air enters the combustion chamber, and mix with the fuel more fully. Under the action of the scraper, when it contacts the first air inlets of different sizes, it can contact the hole wall, and the scraper can facilitate the reverse reset of the first ring.

[0028] As a further improvement to the above solution, the invention further comprises a closed cover arranged outside the combustion chamber and covering the ignition disc and the movable pin, a sealing cover fixedly provided at the front end of the closed cover, an air inlet assembly fixedly provided on the sealing cover for supplying air into the closed cover, and fan blades of the air inlet assembly are coated with a coating to prevent electrostatic adsorption of dust;

[0029] The driving component is arranged on the front end surface of the cover.

[0030] As a further improvement of the above solution, a heat exchanger assembly is sleeved on the outside of the combustion chamber, the heat exchanger assembly and the closed cover are fixed to each other, and an exhaust pipe is provided in the heat exchanger assembly to facilitate exhaust of the combustion chamber.

[0031] The technical effect of the above improvement is: by providing a coating on the fan blades of the air inlet assembly, the erosion and accumulation of dust on the blade surface and the influence of frictional electric field force can be reduced, the dynamic balance mutation caused by dust during the rotation of the motor can be reduced, and the force configuration of the supporting bearings can be reduced, thereby improving the service life of the motor and the air volume efficiency.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the technical solution, the technical solution is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0047] Referring to Figures 1-13, in a specific embodiment, a self-dusting multi-ignition point co-heating fuel oil heater includes a combustion chamber 10. The combustion chamber 10 is in the shape of a circular tube. The outer side of the combustion chamber 10 is provided with a plurality of first air inlets 101 that extend through the combustion chamber 10. Referring to Figures 6 and 7, the first air inlets 101 are arranged tangentially along the diameter of the combustion chamber 10. This allows air to enter the combustion chamber 10 and generate a vortex when entering, thereby facilitating sufficient mixing with the fuel.

[0048] An ignition plate 11 is fixedly mounted on the combustion chamber 10 near the air inlet end. The ignition plate 11 covers the air inlet end of the combustion chamber 10 and is fixedly mounted thereto. A volatilization chamber 111 is disposed within the ignition plate 11. Referring to FIG. 11 , a feed pipe 112 is connected to one side of the volatilization chamber 111. The fuel to be combusted enters the volatilization chamber 111 through the feed pipe 112. The volatilization chamber 111 is a hollow cylindrical structure, and a plurality of volatilization nets 115 are disposed on the circumferential sidewalls of the volatilization chamber 111.

[0049] An igniter 113 is also provided in the ignition disk 11; a plurality of second air inlets 114 communicating with the interior of the combustion chamber 10 are provided on the end surface of the ignition disk 11. The positions of the volatilization net 115 and the second air inlets 114 correspond to each other. The second air inlets 114 are arranged in a circular array around the volatilization chamber 111. In this embodiment, the second air inlets 114 are set according to the landing area of ​​the intake wind force and the gravity density of the oil. Six second air inlets 114 and the volatilization net 115 are provided. The provision of six second air inlets 114 can facilitate the dispersion of the intake air, can maintain the combustion of the burner in a dusty environment, and reduce the phenomenon of burner misfire.

[0050] The air intake side of the ignition disk 11 is movably provided with a movable pin 12 which can be inserted into the second air intake port 114 to clean the second air intake port 114. The movable pin 12 is connected to a driving component 27 for driving its movement. Please refer to Figures 2 or 3. In this embodiment, the driving component 27 is a motor. After the motor is started, it can drive the movable pin 12 to be inserted into the second air intake port 114 and move. When the movable pin 12 is inserted into the second air intake port 114, the movable pin 12 can push away the dust in the hole of the second air intake port 114, thereby facilitating the air to smoothly enter the combustion chamber 10 from the second air intake port 114, thereby improving the combustion efficiency.

[0051] As shown in Figures 5, 6, 7, 8 and 9, as a preferred embodiment of the above embodiment, in order to allow the movable pin 12 to automatically rebound and open the second air inlet 114 after being inserted into the second air inlet 114, a connecting plate 14 is provided between several movable pins 12, and the connecting plate 14 fixes all the movable pins 12 together to play a role in synchronous control; the connecting plate 14 and the ignition disk 11 are arranged to slide with each other, and the connecting plate 14 and the ignition disk 11 can only slide with each other and cannot rotate with each other, so as to ensure that the movable pin 12 can be smoothly inserted into the second air inlet 114 without angular deflection or inability to insert. A spring 15 is provided between the connecting plate 14 and the ignition disk 11, and the spring 15 pushes the connecting plate 14 outward to make the movable pin 12 slide out of the second air inlet 114.

[0052] A guide member 16 protruding outward is provided on the outer end face of the ignition disk 11. In this embodiment, the guide member 16 is a guide column fixed on the end face of the ignition disk 11. A push head 17 that can press the movable pin 12 is slidably provided on the guide member 16. The push head 17 is threadedly connected to the main shaft 18, and the main shaft 18 is power-connected to the drive assembly 27. When the motor is started, it can drive the main shaft 18 to rotate, and the main shaft 18 drives the push head 17 to move toward the side of the connecting plate 14. Under the guidance of the guide member 16, the push head 17 squeezes the connecting plate 14, so that the movable pin 12 is inserted into the second air inlet 114, and the dust in the second air inlet 114 is cleaned.

[0053] As a preferred embodiment of the above, the outer side of the combustion chamber 10 is rotatably sleeved with a first collar 13, and the first collar 13 is provided with a plurality of first extension rods 131 extending along its axial direction. In this embodiment, the first extension rod 131 is a part of the first collar 13, and the first extension rod 131 is provided with a plurality of cleaning members 132 that can be extended into the first air inlet 101. Specifically, the cleaning member 132 is a part extending from the first extension rod 131, and a scraper 133 is fixedly provided at the end of the cleaning member 132. The scraper 133 protrudes outward along the tangential direction of the cleaning member 132 and is arranged at an inclined angle. Referring to FIG. 10 , when the cleaning member 132 moves in the first air inlet 101 , to clean the first air inlet 101, the scraper 133 set can ensure that the cleaning member 132 contacts the inner hole wall of the first air inlet 101 of different sizes when the cleaning member 132 enters the first air inlet 101, thereby cleaning the dust condensed on the first air inlet 101, and under the effect of the inclined arrangement of the scraper 133, when the cleaning member 132 withdraws from the first air inlet 101, it can expand through spontaneous deformation and withdraw quickly and conveniently. In addition, when the scraper 133 is in an inclined state, before it enters the first air inlet 101, it can guide the air supply, so that the air supply can pass through the first air inlet 101 and enter the combustion chamber 10 to participate in combustion.

[0054] As shown in Figures 9, 10, and 13, as a preferred embodiment of the above embodiment, a movable ring 19 is sleeved on the main shaft 18. In this embodiment, the main shaft 18 and the movable ring 19 can slide and rotate relative to each other. A protruding second extension rod 191 is provided at one end of the movable ring 19. Referring to Figure 10, the second extension rod 191 is specifically a part of the movable ring 19 and extends along the axis of the movable ring 19. The end of the second extension rod 191 is provided with an outwardly protruding guide pin 192. In this embodiment, the guide pin 192 is specifically an outwardly protruding cylindrical pin provided on the second extension rod 191.

[0055] A rotating member 20 is fixed to the outer side of the first ferrule 13. In this embodiment, the rotating member 20 is a rotating cylinder. Specifically, the rotating member 20 is sleeved on the outer side of the first ferrule 13, with a gap therebetween for air supply. The two are fixed to each other by a welded connecting block. For details, please refer to Figures 5 and 6. The rotating member 20 has a first guide portion 201 that can be slidably arranged with the guide pin 192. In this embodiment, the first guide portion 201 is a through-long strip groove and is arranged obliquely. The specific inclination direction is along the direction in which the rotating member 20 is to be moved along the movable ring 19, gradually away from the movable ring 19. For details, please refer to Figure 10.

[0056] A reset member 21 for pulling the rotating member 20 back is also provided between the rotating member 20 and the combustion chamber 10. In this embodiment, the reset member 21 is a pulling spring, and in order to ensure that the movable ring 19 can synchronously drive the rotating member 20 to rotate together during the rotation process, a rough surface is provided between the second extension rod 191 and the rotating member 20 to increase the friction between the two, and to ensure that the friction between the second extension rod 191 and the rotating member 20 is greater than the pulling force of the reset member 21. In addition, a limiting groove 203 is provided on the first guide part 201. The limiting groove 203 is a part of the first guide part 201 that is recessed inwardly, and has a smooth transition with the first guide part 201. Referring to Figure 13, it can partially restrict the guide pin 192, ensuring that when the movable ring 19 drives the rotating member 20 to rotate, the rotating member 20 first rotates following the movable ring 19, and then when the rotating member 20 cannot rotate, the guide pin 192 can move in the first guide part 201.

[0057] As shown in FIG10 , as a preferred embodiment of the above embodiment, a first toggle member 181 arranged along its diameter direction is fixedly provided on the main shaft 18, and a second toggle member 193 which can contact and move with the first toggle member 181 is provided on the end surface of the movable ring 19. The second toggle member 193 is arranged along the axial direction of the movable ring 19, and the second toggle member 193 and the first toggle member 181 are both provided with outwardly protruding toggle rods. When the main shaft 18 rotates, the first toggle member 181 contacts the second toggle member 193 and synchronously drives the second toggle member 193 to rotate, thereby prompting the movable ring 19 to rotate. At this time, the movable ring 19 can drive the rotating member 20 to rotate, so that the first ferrule 13 cleans the first air inlet 101, and when the main shaft 18 rotates, it will synchronously drive the push head 17 to move toward the side of the connecting plate 14. Therefore, when the main shaft 18 rotates, the second air inlet 114 and the first air inlet 101 can be cleaned synchronously.

[0058] When the rotating member 20 cannot rotate, the first toggle member 181 still toggles the second toggle member 193 to rotate. At this time, under the guidance of the first guide portion 201, the guide pin 192 moves in the first guide portion 201, so that the movable ring 19 moves toward the side of the rotating member 20 while rotating, until the first toggle member 181 and the second toggle member 193 cannot contact each other. At this time, the first toggle member 181 has lost its toggle effect on the second toggle member 193. Under the pull of the reset member 21, the rotating member 20 rotates in the opposite direction and resets, and the movable ring 19 will also reset, thereby pulling out the first extension rod 131 inserted into the first air inlet 101. When the main shaft 18 continues to rotate, it will not toggle the second toggle member 193 again, and will drive the push head 17 to press the connecting plate 14 to complete the reset of the second air inlet 11 4, so it can be ensured that when the first air inlet 101 and the second air inlet 114 are cleaned, there is always one in the open state, and the air intake will not be completely closed, so as to ensure the combustion of the fuel in the heater and the fire will not be cut off. When the driving component 27 drives the main shaft 18 to rotate in the opposite direction, although the first toggle member 181 cannot play the role of toggling the second toggle member 193, the push head 17 will move toward the side of the movable ring 19 until the push head 17 and the movable ring 19 contact and push the movable ring 19 to move toward the side of the main shaft 18. At this time, the guide pin 192 moves under the guidance of the first guide part 201, and the first toggle member 181 and the second toggle member 193 can contact each other again until the guide pin 192 cannot move in the first guide part 201, and the driving component 27 drives the main shaft 18 to stop rotating;

[0059] As shown in FIG9 , as a preferred embodiment of the above-mentioned embodiment, an inner liner 23 is rotatably arranged on the outer circumference of the rotating member 20. The inner liner 23 is provided mainly to facilitate the rotation of the outer shell 22. The rotating member 20 is also provided with a plurality of penetrating second guide portions 202. The second guide portions 202 are also provided with long strip-shaped penetrating grooves, but are arranged along the outer circumference of the rotating member 20 without tilting, and are only used to limit the rotation of the second guide portions 202. The inner liner 23 is provided with a plurality of limit pins that can move relative to each other in the second guide portions 202. The limit pins move in the second guide portions 202, mainly to limit the rotation range of the rotating member 20.

[0060] An outer shell 22 is fixedly provided on the outer circumference of the inner liner 23. The outer shell 22 and the combustion chamber 10 are fixed to each other and completely cover the first air inlet 101. The outer shell 22 is mainly used to isolate the air supply component 26 from the outside world and ensure that the air supply can enter the combustion chamber 10 through the first air inlet 101 and the second air inlet 114 to participate in combustion.

[0061] As shown in Figures 1, 2, and 4, as a preferred embodiment of the above embodiment, it also includes a closed cover 24 arranged outside the combustion chamber 10 and covering the ignition disk 11 and the movable pin 12. The closed cover 24 is in the shape of a pipe, and the outer shell 22 and the closed cover 24 are sealed and fixed to each other. A cover 25 is fixedly provided at the front end of the closed cover 24, and a drive assembly 27 is provided on the front end surface of the cover 25. An air inlet assembly 26 for supplying air into the closed cover 24 is fixedly provided on the cover 25. The fan blades of the air inlet assembly 26 are coated with a coating that prevents electrostatic adsorption of dust. The provided coating is an organic matter coated on the blades. The organic coating can adopt the adhesion effect to effectively solve the problem of dust erosion and frictional electric field force on the blade surface; thereby improving the life of the motor and the volumetric efficiency;

[0062] As a preferred embodiment of the above, a heat exchanger assembly 28 is sleeved on the outer side of the combustion chamber 10, and the heat exchanger assembly 28 and the closed cover 24 are fixed to each other. Specifically, the outer shell 22 is fixed between the closed cover 24 and the heat exchanger assembly 28, and an exhaust pipe 29 is provided in the heat exchanger assembly 28 to facilitate the exhaust of the combustion chamber 10. The heat exchanger assembly 28 is mainly filled with water, and is transported by a water pump. The water carries away the combustion heat generated in the heat exchanger assembly 28 for use.

[0063] The specific working principle of the present invention is:

[0064] The air inlet assembly 26 is activated to introduce outside air, which is then fed into the combustion chamber 10 through the second air inlet 114 and the first air inlet 101 for combustion. The feed pipe 112 introduces the fuel into the volatilization net 115 for volatilization and mixing with the air. After the igniter 113 ignites, the fuel ignites and generates heat. The water flowing in the heat exchanger assembly 28 absorbs the generated heat and then transports it away for use.

[0065] When used in a dusty environment and dust removal is required, the driving assembly 27 is started, and the driving assembly 27 drives the main shaft 18 to rotate. When the main shaft 18 rotates, it drives the first toggle member 181 to rotate. The first toggle member 181 will toggle the second toggle member 193 to rotate. The second toggle member 193 drives the movable ring 19 to rotate. The movable ring 19 will synchronously drive the rotating member 20 to rotate. When the rotating member 20 rotates, it drives the first ring 13 to rotate, so that the cleaning member 132 and the scraper 133 extend into the first air inlet 101 to clean the first air inlet 101;

[0066] During the continuous rotation of the main shaft 18, the rotating member 20 is limited by the limit pin on the inner liner 23 and cannot continue to rotate. At this time, the first toggle member 181 drives the second toggle member 193 to continue rotating. The guide pin 192 moves away from the main shaft 18 under the guidance of the first guide portion 201 until the first toggle member 181 and the second toggle member 193 are completely disengaged. Then, under the pull of the reset member 21, the rotating member 20 and the first ferrule 13 rotate in the opposite direction to reset.

[0067] The main shaft 18 continues to rotate to drive the push head 17 to move toward the side of the connecting plate 14, thereby pushing the connecting plate 14 and the movable pin 12 to move, causing the movable pin 12 to extend into the second air inlet 114, thereby cleaning the dust in the second air inlet 114. Therefore, each time cleaning is performed, the cleaning processes in the first air inlet 101 and the second air inlet 114 are separated to avoid being carried out at the same time, thereby preventing the air from being blocked and unable to enter the combustion chamber 10 to participate in combustion and causing a misfire. In addition, the multiple second air inlets 114 and the volatile net 115 are arranged in corresponding positions, so that the fuel and air are mixed more evenly, reducing incomplete combustion, and thus reducing carbon deposits in the combustion chamber 10.
