Technical Field:

[0001] The present invention belongs to the technical field of a flame outlet adjusting structure of a combustion device, and particularly relates to an all-oxygen combustion device with an adjustable flame outlet. Background Art:

[0002] An all-oxygen burner refers to mixing fuel and oxygen step by step in a furnace to make it evenly distributed in the furnace for diffusion combustion, improving the combustion sufficiency, reducing the fuel consumption, and greatly reducing the flue gas emissions, thereby improving the environmental protection of equipment application.

[0003] The flame in the all-oxygen combustion device furnace will be ejected through the nozzle to heat the required equipment. Currently, the size of the nozzle of the combustion device is fixed, resulting in limited flame shape and coverage area of the ejected flame and inability to be flexibly adjusted according to needs. Therefore, an all-oxygen combustion device with an adjustable flame outlet is proposed herein. Summary of the Invention:

[0004] The purpose of the present invention is to provide an all-oxygen combustion device with an adjustable flame outlet to solve the problem that the size of the nozzle of the current combustion device is fixed, resulting in limited flame shape and coverage area of the ejected flame and inability to be flexibly adjusted according to needs.

[0005] To solve the above problems, the present invention provides an all-oxygen combustion device with an adjustable flame outlet, including a burner. One end of the burner is fixedly connected with a flame outlet, and an outer sleeve is sleeved outside the flame outlet. One end of the outer sleeve is fixedly connected with a connection plate. A toggle plate is rotatably connected inside the connection plate. The toggle plate is of a ring structure. One end of the connection plate away from the outer sleeve is detachably connected with a front cover plate. A plurality of gate plates are evenly rotatably connected inside the front cover plate. Through holes with the same diameter as the flame outlet are respectively formed through the connection plate and the front cover plate;

[0006] One end of the front cover plate and the side wall near the through hole are detachably connected with an extension pipe. A plurality of adjusting plates are evenly rotatably connected at the end of the extension pipe away from the front cover plate. The adjusting plates are of a conical structure with a curvature.

[0007] Preferably, a limiting groove is fixedly connected to the inner wall of the connection plate. The limiting groove is of a ring structure. A positioning plate is rotatably connected inside the limiting groove. One end of the positioning plate is fixedly connected to one side wall of the toggle plate. A plurality of slots are evenly formed on the side of the toggle plate away from the positioning plate. A plurality of fixing columns are evenly fixedly connected to the inner wall of the front cover plate. The number of the fixing columns corresponds to that of the slots.

[0008] The limiting groove and positioning plate are established to ensure smooth rotation of the toggle plate, and the slot is opened to connect with one end of the gate plate, so that the rotation of the toggle plate can drive the gate plate to rotate synchronously, thereby realizing the function of adjusting the diameter of the communication port by rotating the gate plate.

[0009] Preferably, the gate plate is an arc-shaped structure, a rotating hole is opened through one end of the gate plate, the gate plate is rotatably sleeved on the corresponding fixed column through the rotating hole, the side wall of the gate plate at one end away from the rotating hole is fixedly connected with a plug column, the plug column is slidably inserted in the slot, the gate plate is an arc-shaped structure, the number of the gate plates is the same as the fixed column, and the gate plates are in a stacked state, and the inner ring wall of the toggle plate and the gate plate is in the same plane as the inner ring wall of the connecting port.

[0010] Sliding the plug post into the slot ensures that the plug post is smoothly driven to move when the toggle plate rotates, avoiding motion interference and ensuring smooth adjustment. Because the gate plate is a stacked arc structure, the flatness of the gate plate after storage is guaranteed.

[0011] Preferably, a side wall of one side of the outer sleeve is detachably connected to a mounting box, a motor is detachably connected inside the mounting box, an output end of the motor is detachably connected to a gear through the side wall of the mounting box, a connecting hole is formed through the side wall of one side of the connecting plate, the gear rotates in the connecting hole, and the gear extends into the connecting plate through the connecting hole, the outer ring wall of the toggle plate is evenly fixedly connected with saw teeth, and the gear is meshingly connected with the saw teeth on the toggle plate.

[0012] The starting motor drives the gear to rotate, and through the meshing connection, the gear can drive the toggle plate to rotate, thereby realizing automatic rotation adjustment of the gate plate and achieving the effect of automatic adjustment of the diameter of the communication port.

[0013] Preferably, the outer ring wall of one end of the outer sleeve away from the connecting plate is fixedly connected with a connecting flange, and screws are inserted and rotatably connected to the connecting flange. The connecting plate is detachably connected to one end of the burner through the connecting flange and the screws. An insert column is provided in the middle of the outer sleeve, and the insert column is fixedly connected to the side wall of the connecting plate near the connecting port. The inner wall of the insert column and the inner ring wall of the connecting port are in the same plane, and the inner ring wall of the outer sleeve and the outer ring wall of the insert column are fixedly connected with a sealing gasket.

[0014] Because the connecting plate is fixed to the burner by screws, it is convenient for later disassembly and maintenance. The established inner plug-in column and outer sleeve can ensure the stability of the connection with the flamethrower. At the same time, the established sealing gasket can ensure the tightness of the connection while improving the sealing.

[0015] Preferably, the outer wall of the extension tube close to the adjustment plate is fixedly connected with threaded teeth, the end of the extension tube away from the front cover plate is sleeved with a rotating ring, the inner ring wall of the rotating ring is fixedly connected with a spiral coil, and the rotating ring is threadably connected to the threaded teeth on the extension tube through the spiral coil.

[0016] By rotating the rotating ring, the rotating ring can be driven to move back and forth on the extension tube through the threaded connection. The movement and extension of the rotating ring can limit the adjustment plate, thereby controlling the outward expansion angle of the adjustment plate, thereby adjusting the size of the opening.

[0020] The established guide slope can ensure that the flame enters the crater smoothly to avoid obstruction. At the same time, the established groove can ensure the leveling effect of the inner wall of the inserted column and the inner wall of the crater, ensuring the smooth ejection of the flame.

[0021] The beneficial effects of the present invention are as follows: when needed, the motor is started to drive the gear to rotate, and the rotating gear drives the toggle plate to rotate synchronously.

Specific implementation method:

[0032] like Figure 1-7 As shown, this specific embodiment adopts the following technical scheme: a full oxygen combustion device with adjustable flamethrower, comprising a burner 1, one end of the burner 1 is fixedly connected with a flamethrower, and an outer sleeve 5 is connected to the flamethrower outer shell, one end of the outer sleeve 5 is fixedly connected with a connecting plate 7, a toggle plate 23 is rotatably connected in the connecting plate 7, the toggle plate 23 is an annular structure, the end of the connecting plate 7 away from the outer sleeve 5 is detachably connected with a front cover plate 8, a gate plate 18 is evenly rotatably connected in the front cover plate 8, a connecting port 16 is opened through the middle of the connecting plate 7 and the front cover plate 8, and the caliber of the connecting port 16 is the same as that of the flamethrower;

[0033] A limiting groove 26 is fixedly connected to the inner wall of the connecting plate 7. The limiting groove 26 is an annular structure. A positioning plate 27 is rotatably connected in the limiting groove 26. One end of the positioning plate 27 is fixedly connected to a side wall of the toggle plate 23. A slot 24 is evenly provided on the side of the toggle plate 23 away from the positioning plate 27. The inner wall of the front cover 8 is evenly fixedly connected with fixing columns 17. The number of fixing columns 17 corresponds to the slot 24. The gate plate 18 is an arc-shaped structure. A rotating hole 19 is provided through one end of the gate plate 18. The gate plate 18 is rotatably sleeved on the corresponding fixing column 17 through the rotating hole 19. The side wall of the gate plate 18 away from the rotating hole 19 is fixedly connected with an insertion column 20. The insertion column 20 is slidably inserted in the slot 24. The gate plate 18 is an arc-shaped structure. The number of gate plates 18 is the same as that of the fixing columns 17, and the gate plates 18 are in a stacked state. The inner ring walls of the toggle plate 23 and the gate plate 18 are in the same plane as the inner ring wall of the connecting port 16.

[0034] The technical effect of this solution is as follows: as the toggle plate 23 rotates, one end of the gate plate 18 can be driven to move, and at this time the gate plate 18 will rotate and move along the connection point between the rotating hole 19 and the fixed column 17, and the stacked gate plates 18 will gradually disperse in the process, and because it is a stacked structure, even the dispersed gate plates 18 are staggered with each other to ensure airtightness, and as the gate plate 18 moves, the diameter of the communication port 16 can be adjusted, thereby adjusting the size of the flame outlet and the size of the flame sprayed out. At the same time, because the gate plate 18 is an arc-shaped structure, it is always in a circular state during the adjustment process, and in order to ensure the smooth rotation of the toggle plate 23, a limiting groove 26 and a positioning plate 27 are set to limit the toggle plate 23 to avoid problems such as deflection during rotation.

[0035] A mounting box 22 is detachably connected to a side wall of the outer sleeve 5, a motor 25 is detachably connected inside the mounting box 22, an output end of the motor 25 is detachably connected to a gear 21 through the side wall of the mounting box 22, a connecting hole is provided through the side wall of the connecting plate 7, the gear 21 is rotatably set in the connecting hole, and the gear 21 extends into the connecting plate 7 through the connecting hole, the outer ring wall of the toggle plate 23 is evenly fixedly connected with saw teeth, and the gear 21 is meshed with the saw teeth on the toggle plate 23.

[0036] The technical effect of this solution is as follows: a motor 25 is connected inside the installation box 22, and the motor 25 can drive the gear 21 to rotate, and the toggle plate 23 is driven to rotate synchronously through the meshing connection between the gear 21 and the toggle plate 23, so that the size of the flamethrower can be remotely controlled to improve the convenience and flexibility of application, and connecting the motor 25 inside the installation box 22 can protect the motor 25 and avoid the influence of high temperature on it.

[0037] One end of the outer sleeve 5 away from the connection plate 7 is fixedly connected with a connection flange 6. Screws are inserted and rotatably connected to the connection flange 6. The connection plate 7 is detachably connected to one end of the burner 1 through the connection flange 6 and the screws. An inner insertion column 14 is provided in the middle of the outer sleeve 5. The inner insertion column 14 is fixedly connected to the side wall of the connection plate 7 close to the communication port 16. The inner wall of the inner insertion column 14 and the inner wall of the communication port 16 are in the same plane. Sealing gaskets 15 are fixedly connected to the inner wall of the outer sleeve 5 and the outer wall of the inner insertion column 14 respectively.

[0038] The technical effects of this solution are as follows: The connection flange 6 and the screws can improve the convenience of disassembly and assembly between the equipment and the burner 1, and improve the maintenance efficiency of the adjustment component in the later stage. The outer sleeve 5 and the inner insertion column 14 can increase the connection stability, and at the same time ensure that the flame can smoothly spray out from the adjustment component. At the same time, the sealing gaskets 15 can increase the connection stability and improve the sealing performance, avoiding leakage problems.

[0039] One end of the front cover plate 8 and the side wall close to the communication port 16 are detachably connected with an extension pipe 9. The end of the extension pipe 9 away from the front cover plate 8 is evenly rotatably connected with adjustment plates 11. The adjustment plates 11 are conical structures with arcs. The outer wall of the extension pipe 9 close to the adjustment plates 11 is fixedly connected with thread teeth 28. A rotating ring 10 is sleeved on the end of the extension pipe 9 away from the front cover plate 8. The inner wall of the rotating ring 10 is fixedly connected with a thread ring 29. The rotating ring 10 is threadedly rotated with the thread teeth 28 on the extension pipe 9 through the thread ring 29. The adjustment plates 11 are mutually attached. An activity groove 30 is formed on one side wall of each adjustment plate 11. One end of the adjustment plate 11 away from the activity groove 30 is fixedly rotatably connected with a follower plate 31. The follower plate 31 is inserted into the activity groove 30, and the follower plate 31 and the activity groove 30 are conical structures with arcs corresponding to the adjustment plates 11. When the adjustment plates 11 are in the closed state, there is a minimum opening, and the opening corresponds to the communication port 16.

[0040] The technical effects of this solution are as follows: When spraying fire, an outward thrust will be generated. Without limitation, the flame will be radial and uncontrollable. Therefore, the adjustment plates 11 are provided to limit the flame so that it can be sprayed out in a concentrated manner. By rotating the rotating ring 10 to control the length of the dimension extended from the extension pipe 9, the expansion angle of the adjustment plates 11 can be controlled, thereby adjusting the flame state. At the same time, through the provided activity grooves 30 and follower plates 31, it is ensured that the adjustment plates 11 can contract and expand while preventing the flame from escaping from the gaps of the adjustment plates 11.

[0041] One end of the burner 1 away from the outer sleeve 5 is fixedly connected to the material pipe 3, one side wall of the burner 1 is detachably connected to two oxygen tubes 2, and valves are connected to the two oxygen tubes 2, and the bottom side wall of the burner 1 is detachably connected to the support base 4, a furnace chamber 12 is opened in the burner 1, and an inclined guide slope 13 is set at one end of the furnace chamber 12 close to the inner plug column 14, and a groove is opened on the inner wall of the flame nozzle, and the thickness of the groove is the same as the thickness of the inner plug column 14.

[0042] The technical effect of this solution is as follows: the established guide slope 13 can ensure the smooth ejection of the flame, avoid the impact of the flame and the inner wall of the burner 1 to affect the smoothness of the flame ejection, and the established groove can also ensure the smoothness of the flame ejection.

[0043] Specifically: when in use, first start the motor 25 to drive the gear 21 to rotate. As the gear 21 rotates, the toggle plate 23 can be driven to rotate synchronously. Because the plug post 20 slides in the slot 24, when the toggle plate 23 rotates, it can drive one end of the gate plate 18 to move, thereby driving the gate plate 18 to rotate along the fixed column 17. As the gate plate 18 rotates, the diameter of the connecting port 16 can be adjusted, thereby adjusting the size of the ejected flame. The expansion and storage of the gate plate 18 can be controlled by adjusting the rotation direction of the gear 21 to increase the flexibility of application. When the flame passes through the adjusted connecting port 16 and enters the extension tube 9, it is finally ejected from the adjustment plate 11. However, before that, the rotating ring 10 is rotated first to extend one end of the rotating ring 10 outward through the principle of threaded connection. The restriction on the adjustment plate 11 is different according to the different extension sizes, thereby controlling the expansion angle of the adjustment plate 11 and adjusting the posture of the flame.
