Description

Technical Field

[0001] This invention relates to the field of gas burner technology, and in particular to a flame heating device for a cleaning machine. Background Technology

[0002] High-temperature cleaning machines are efficient and environmentally friendly cleaning equipment widely used in industrial, commercial, and specialized fields. Their core principle is to remove stubborn stains using high-temperature, high-pressure media (such as steam or hot water), while also providing disinfection. The flame heating device heats the cleaning medium by burning fuels such as diesel or natural gas, bringing it to a predetermined temperature.

[0003] Existing cleaning machines using flame heating devices heat water pipelines by generating flames and high-temperature flue gas from diesel or natural gas combustion. Heat exchange occurs as the water flows through the pipelines to achieve the heating effect. However, during actual combustion, the flames and high-temperature flue gas flow directly upwards. To address this, a flame deflector is typically used to block the flame direction and prevent the direct discharge of high-temperature flue gas. However, in practice, because the position of the flame deflector is fixed, the direction and flow path of the flames and high-temperature flue gas cannot be adjusted, making it difficult to fully utilize the heat from the high-temperature flue gas and consequently affecting energy efficiency.

A traction rod is fixedly connected to the outer surface of the lower end of the paddle, and a baffle is fixedly connected to the lower end of the traction rod.

[0011] Preferably, a flow-diverting component is provided on the inner side of the top ring. The flow-diverting component includes an air hole that passes through the outer surface of the top ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

This enables the water to achieve a stable heating effect under different flue gas generation levels, helping to ensure that the water outlet temperature reaches the predetermined standard. While improving the heat utilization efficiency of the flue gas, it can also effectively improve the water heating accuracy, thereby improving the heat utilization efficiency of the flue gas to a certain extent. 2. This solution, by setting up a flow-blocking component, can prevent the flue gas from being discharged outward through the air guide pipe when the amount of flue gas generated is small. This can effectively prolong the residence time of the flue gas inside the combustion cylinder, which helps to fully utilize the heat of the flue gas to heat the coil, thereby effectively improving the heating effect of the flue gas on the coil. When the flue gas generated by combustion flows upward, the baffle can block the flue gas, which can not only change the flow path of the flue gas, but also prevent some flue gas from directly entering the air guide pipe and causing additional waste of flue gas heat. 3. This solution, by setting up a diversion component, allows some flue gas to pass through the vents on the surface of the top ring under the obstruction of the baffle plate. As the flue gas flows horizontally, it can blow the high-temperature flue gas to the gap between the coil and the combustion cylinder, and make the flue gas flow downward from the gap between the coil and the combustion cylinder. This allows the flue gas to come into contact with different positions of the coil, which not only improves the heat exchange efficiency between the flue gas and water, but also further improves the heating efficiency of the water.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 The present invention provides a technical solution: A flame heating device for a cleaning machine includes a body 11, a heating tank 12 is provided on the upper side of the body 11, a combustion cylinder 18 for mounting a coil 19 is provided on the inner surface of the heating tank 12, the coil 19 is used to heat water, a top ring 47 is fixedly connected to the inner surface of the heating tank 12, a support frame 28 is fixedly connected to the inner surface of the top ring 47, and an adjustment component is provided on the upper side of the support frame 28 for adjusting the direction of the flame and smoke. A flow guiding component is provided on the outside of the support frame 28. The flow guiding component is used to guide the flue gas. The adjustment component includes an adjustment plate 36 fixedly connected to the upper end of the support frame 28. A top rod 49 is fixedly connected to the outer surface of the upper end of the support frame 28. A hinge seat 39 is slidably connected to the outer surface of the top rod 49. A hinge rod 37 is hinged between the hinge seat 39 and the adjustment plate 36.

[0021] An end cap 38 is fixedly connected to the outer surface of the top rod 49. A deformation groove 40 is embedded in the outer surface of the adjusting plate 36. The number of adjusting plates 36 and hinge rods 37 are several groups and arranged in a ring array. The adjusting plate 36 is made of elastic material. The support frame 28 has a T-shaped structure.

[0022] By adopting the above technical solution, the cleaning machine body 11 is equipped with a heating tank 12, a pump body, and other equipment. The heating tank 12 is mainly used to heat the water. During operation, the water flows from bottom to top inside the coil 19 under pressure. At the same time, the flame and high-temperature flue gas generated by combustion enter the heating tank 12. The flame and high-temperature flue gas come into contact with the outer surface of the coil 19, heating the water through the coil 19. Then, the cleaning machine uses the warm water flow for rinsing and cleaning. After the flame and high-temperature flue gas enter the combustion cylinder 18 from inside the top ring 47, the high-temperature flue gas will... In order to improve the contact effect between the flame, high-temperature flue gas and the coil 19, an adjustment component is set up. The top ring 47 is used to support the support frame 28, and the upper end of the support frame 28 is used to support the adjustment plate 36. Several sets of adjustment plates 36 arranged in a ring array will form a cone shape. After the flue gas flows upward from the top ring 47, the high-temperature flue gas diffuses in all directions under the guidance of the adjustment plate 36, thereby adjusting the flow path of the high-temperature flue gas so that the high-temperature flue gas can fully contact the outer surface of the coil 19, thereby improving the flue gas heat utilization efficiency to a certain extent. When the amount of flue gas generated decreases, the impact force of the high-temperature flue gas on the regulating plate 36 also decreases. At this time, the regulating plate 36 will rotate downwards and deform under the action of the hinge seat 39 and its own gravity. The deformation groove 40 opened on the surface of the regulating plate 36 can reduce the deformation resistance of the regulating plate 36 to a certain extent. The regulating plate 36 and the hinge seat 39 are connected by the hinge rod 37. The end cap 38 at the upper end of the top rod 49 can limit the hinge seat 39, thereby preventing the hinge seat 39 from accidentally sliding off the surface of the top rod 49. When several sets of regulating plates 36 expand outward, the angle between the regulating plate 36 and the horizontal direction will gradually decrease. At this time, the distance between the side of the regulating plate 36 away from the top rod 49 and the coil 19 gradually increases, thereby guiding the flue gas to the surface of the coil 19, making the contact between the flue gas and the coil 19 more uniform. When the amount of flue gas generated increases, the impact force of the flue gas on the regulating plate 36 also increases. At this time, the regulating plate 36 gradually flips and converges under the impact force of the flue gas. The distance between the regulating plate 36 and the coil 19 gradually increases, thereby adjusting the distance between the regulating plate 36 and the coil 19. This can shorten the residence time of the flue gas inside the combustion chamber 18 to a certain extent. By setting the regulating component, the flow path of the flue gas can be adjusted according to the fluctuation of the amount of flue gas generated, thereby adjusting the residence time of the flue gas inside the combustion chamber 18. This can achieve a stable heating effect on the water under different flue gas generation conditions, helping to ensure that the water outlet temperature reaches the predetermined standard. This not only improves the efficiency of flue gas heat utilization but also effectively improves the water heating accuracy.

[0023] Specifically, such as Figure 3 and Figure 6 As shown, the flow guiding assembly includes a movable seat 31 that is slidably connected to the outer surface of the support frame 28. A slot 33 is embedded in the outer surface of the movable seat 31. A pin 34 is fixedly connected to the inner surface of the slot 33. A spoiler 35 is rotatably connected to the outer surface of the pin 34. A limit plate 29 is fixedly connected to the outer surface of the support frame 28. A cavity 32 is embedded in the inner side of the limit plate 29. A spring 30 is fixedly connected to the outer surface of the upper end of the limit plate 29. The spring 30 is sleeved on the outside of the support frame 28.

[0024] By adopting the above technical solution, the support frame 28 supports the spring 30 through the limiting plate 29. The spring 30 applies a certain elastic force to the movable seat 31. When the flue gas flows upward, some of the flue gas impacts the movable seat 31, allowing the movable seat 31 to slide back and forth along the outside of the support frame 28. The cavity 32 inside the movable seat 31 can reduce its weight to a certain extent, thereby improving the moving accuracy of the movable seat 31. The movable seat 31 is fixedly supported by the pin 34 through the slot 33. The spoiler 35 can rotate around the pin 34. During the sliding process of the movable seat 31 along the outside of the support frame 28, the spoiler 35 is pulled by the pin 34. The angle of the baffle 35 can be adjusted, and the limiting plate 29 elastically supports the movable seat 31 through the spring 30. The baffle 35 will fluctuate under the impact of the flue gas. By changing the angle of the baffle 35, the flue gas path can be adjusted, thereby delivering the flue gas to different positions inside the combustion cylinder 18, which can improve the contact effect between the flue gas and the coil 19. During the contact between the flue gas and the baffle 35, the blocking effect of the baffle 35 will disturb the warm airflow, so that the warm gas can generate irregular flow inside the combustion cylinder 18, which can effectively improve the contact effect between the warm gas and the coil 19, and further improve the heating effect of the high temperature flue gas on the coil 19.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, a base 13 is provided on the lower outer surface of the heating tank 12, a flame burner 23 is provided on the inner side of the base 13, a fixing bracket 22 is fixedly connected between the base 13 and the heating tank 12, a tank cover 15 is threadedly connected to the upper side of the outer surface of the heating tank 12, a fixing rod 48 is fixedly connected to the inner surface of the combustion cylinder 18, and the fixing rod 48 is fixedly connected to the outer surface of the coil 19.

[0026] A combustion tube 16 is fixedly connected to the outer surface of the flame burner 23. The combustion tube 16 extends to the outside of the base 13. A water inlet pipe 14 is fixedly connected to the lower end of the coil 19, and a water outlet pipe 17 is fixedly connected to the upper end of the coil 19. Both the water inlet pipe 14 and the water outlet pipe 17 extend to the outside of the heating tank 12. A cover plate 21 is placed on the upper side of the fixing rod 48. A sealing plate 24 is fixedly connected to the outer surface of the upper end of the cover plate 21. The upper end of the sealing plate 24 contacts the inner wall of the combustion cylinder 18. A gas guide pipe 20 is fixedly connected to the outer surface of the upper end of the cover plate 21.

[0027] The upper end of the combustion cylinder 18 is open, and a heat insulation layer is filled between the heating tank 12 and the combustion cylinder 18. The upper end of the gas guide pipe 20 extends to the outside of the tank cover 15.

[0028] By adopting the above technical solution, the base 13 supports the heating tank 12 through the fixing frame 22, and the combustion cylinder 18 is fixedly supported by the fixing rod 48, thereby maintaining an appropriate gap between the coil 19 and the combustion cylinder 18. This helps the flue gas to flow between the coil 19 and the combustion cylinder 18, facilitates contact between the high-temperature flue gas and different positions of the coil 19, and helps to improve the water heating rate. When the cleaning machine is working, the water inlet pipe 14 pressurizes and injects water into the coil 19. Under pressure, the water flows upward in a spiral shape along the inside of the coil 19. The spiral distribution of the coil 19 can prolong the residence time of the water inside the combustion cylinder 18 to a certain extent, and also increases the contact area between the high-temperature flue gas and the coil 19. Then, the heating is completed through the water outlet pipe 17. Water is discharged to the outside of the heating tank 12. The combustion tube 16 continuously delivers the fuel required for combustion to the flame burner 23. The flame burner 23 is located inside the base 13. The high-temperature flue gas and flame generated during the operation of the flame burner 23 enter the combustion cylinder 18 to heat the coil 19. The cover plate 21, together with the sealing plate 24, can seal the upper side of the combustion cylinder 18, thereby reducing the leakage of high-temperature flue gas to a certain extent. While maintaining the internal pressure of the combustion cylinder 18, it can also extend the residence time of high-temperature flue gas inside the combustion cylinder 18 to a certain extent, thereby further improving the energy utilization effect inside the high-temperature flue gas. The heat insulation layer between the heating tank 12 and the combustion cylinder 18 can reduce the heat loss during the combustion process to a certain extent.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, a flow-blocking component is provided inside the air duct 20. The flow-blocking component includes a paddle 25 fixedly connected to the inner surface of the air duct 20. A traction rod 26 is fixedly connected to the outer surface of the lower end of the paddle 25. A turbulence shield 27 is fixedly connected to the lower end of the traction rod 26.

[0030] By adopting the above technical solution, the paddle 25 flips downward under the gravity of the baffle 27 and the traction rod 26, thereby causing several sets of paddles 25 to converge and seal the inside of the air guide pipe 20. The number of paddles 25, traction rods 26 and baffle 27 are all several sets and arranged in a ring array. When the amount of flue gas generated is small, the paddles 25 can prevent the flue gas from being discharged outward through the air guide pipe 20, thereby effectively prolonging the residence time of the flue gas inside the combustion chamber 18, which helps to fully utilize the heat of the flue gas to heat the coil 19, and thus effectively improves the heating effect of the flue gas on the coil 19. When the combustion chamber As the amount of flue gas generated inside the combustion chamber 18 increases, the flue gas pressure inside the combustion chamber 18 gradually increases. The lever 25 is made of elastic material. At this time, the lever 25 undergoes elastic deformation downward under the action of flue gas pressure, so that the flue gas can be discharged outward through the air guide pipe 20 through the gap of the lever 25. The outer surface of the baffle 27 is conical, and the lower end of the baffle 27 is open. When the flue gas generated by combustion flows upward, the baffle 27 can block the flue gas. It can not only change the flow path of the flue gas, but also prevent some of the flue gas from directly entering the air guide pipe 20 and causing additional waste of flue gas heat.

[0031] Specifically, such as Figure 3 and Figure 7 As shown, a flow divider assembly is provided on the inner side of the top ring 47. The flow divider assembly includes an air hole 42 that passes through the outer surface of the top ring 47. A partition groove 44 is embedded in the upper outer surface of the top ring 47. The partition groove 44 is connected to the inside of the air hole 42. A partition plate 43 is slidably connected to the inner side of the partition groove 44. The partition plate 43 is used to seal the air hole 42.

[0032] The lower outer surface of the spoiler 35 is embedded with a guide groove 41. A guide rod 46 is slidably connected to the inner side of the guide groove 41. An ear seat 45 is rotatably connected to the outer surface of the guide rod 46. The lower outer surface of the ear seat 45 is fixedly connected to the partition 43.

[0033] By adopting the above technical solution, the spoiler 35 will fluctuate under the impact of flue gas. When the spoiler 35 moves upward, the guide rod 46 will slide inside the guide groove 41. The guide rod 46 supports the partition 43 through the lug 45. When the spoiler 35 fluctuates upward, the spoiler 35 drives the partition 43 to move upward along the inside of the partition groove 44 through the guide rod 46 and the lug 45. When the partition 43 loses contact with the inside of the air hole 42, under the blocking effect of the spoiler 35, some flue gas will flow out from the top ring 47. The flue gas passes through the surface pores 42. The number of pores 42 and the number of baffles 43 are several and they are arranged in a ring array, which can make the flue gas expand evenly to the surrounding area. As the flue gas flows in the horizontal direction, it can blow the high temperature flue gas to the gap between the coil 19 and the combustion cylinder 18, and make the flue gas flow downward from the gap between the coil 19 and the combustion cylinder 18. This allows the flue gas to come into contact with different positions of the coil 19, which can improve the heat exchange efficiency between the flue gas and water, and further improve the heating efficiency of the water.

[0034] Working Principle: When the cleaning machine is working, the water inlet pipe 14 pressurizes water and injects it into the coil 19. Under pressure, the water flows upward in a spiral shape along the inside of the coil 19. The high-temperature flue gas and flame generated during the operation of the flame burner 23 enter the combustion chamber 18 to heat the coil 19. Several sets of baffles 25 converge to seal the inside of the air guide pipe 20. When the amount of flue gas generated is small, the baffles 25 can prevent the flue gas from being discharged outward through the air guide pipe 20, thereby effectively prolonging the residence time of the flue gas inside the combustion chamber 18. The baffle 27 can block the flue gas, not only changing the flow path of the flue gas, but also preventing some flue gas from directly entering the air guide pipe 20 and causing additional waste of flue gas heat. The upper end of the support frame 28 is used to support the adjusting plate 36. The high-temperature flue gas diffuses in all directions under the guidance of the adjusting plate 36, thereby adjusting the flow path of the high-temperature flue gas. When several sets of adjusting plates 36 expand outward, the adjusting plate 36 and the horizontal direction are aligned. The angle between the adjusting plate 36 and the coil 19 gradually decreases, and the distance between the adjusting plate 36 and the coil 19 on the side away from the top rod 49 gradually increases. This allows the flue gas to be guided to the surface of the coil 19, making the contact between the flue gas and the coil 19 more uniform and sufficient. The baffle 35 can be rotated with the pin 34 as the fulcrum. As the movable seat 31 slides along the outside of the support frame 28, it will pull the baffle 35 through the pin 34, thereby adjusting the angle of the baffle 35. The baffle 35 will generate waves under the impact of the flue gas. The movement of the baffle plate 35 can adjust the flue gas path by changing the angle of the baffle plate 35, thereby delivering the flue gas to different positions inside the combustion cylinder 18. Under the obstruction of the baffle plate 35, some flue gas will pass through the air holes 42 on the surface of the top ring 47. As the flue gas flows horizontally, it can blow the high-temperature flue gas to the gap between the coil 19 and the combustion cylinder 18, and make the flue gas flow downward from the gap between the coil 19 and the combustion cylinder 18, thereby enabling the flue gas to contact different positions of the coil 19.
