Technical Field

[0001] The utility model relates to the technical field of burner swing nozzles, in particular to a burner nozzle amplitude adjustment mechanism and a locking device. Background Art

[0002] The main function of the swing nozzle of the supercritical boiler burner is to change the distribution of the fuel and air mixture in the furnace by adjusting the nozzle angle to adapt to the combustion requirements under different load conditions and achieve NOx emission control, flame stability and efficient combustion.

[0003] However, the current burner nozzle can only swing at a fixed small amplitude, and the swing amplitude cannot be adjusted, and thus cannot be applied to different usage environments. Therefore, we need to solve this problem in a timely manner. Utility Model Content

[0004] In view of the above technical problem or the existing problem in the prior art that the swing amplitude of the nozzle cannot be adjusted, the present utility model is proposed.

[0005] The utility model aims to provide a burner nozzle amplitude adjustment mechanism.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: including:

[0007] The nozzle mechanism includes a nozzle, a crossbar provided on one side of the nozzle, and a roller provided on the nozzle for rotating to reduce wear;

[0008] The main body includes a burner nozzle, an amplifying component provided on one side of the burner nozzle, the burner nozzle and the nozzle are hingedly connected, and an adjusting component provided on the amplifying component for rapid adjustment;

[0009] The fixing mechanism comprises a base and a clamping plate arranged on the inner side of the base, wherein the clamping plate and the base are hinged.

[0010] As a preferred solution of the burner nozzle amplitude adjustment mechanism of the utility model, wherein: the amplification component includes a turntable, the turntable is rotatably connected to one side of the burner nozzle, one side of the turntable is rotatably connected to an eccentric disk, an arc-shaped groove is provided on the inner side of the eccentric disk, a positioning rod is provided on the inner side of the arc-shaped groove, and the positioning rod is fixedly installed on one side of the turntable.

[0011] As a preferred solution of the burner nozzle amplitude adjustment mechanism of the utility model, the adjustment component includes a hollow tube, which is fixedly mounted on one side of the turntable, a sprocket is provided at one end of the hollow tube, a circular ring is rotatably connected to the outer side of the hollow tube, and an arc-shaped protrusion is provided on the outer side of the circular ring.

[0012] As a preferred solution of the burner nozzle amplitude adjustment mechanism of the present invention, the number of the eccentric disks and arc-shaped protrusions is set to multiple, and the multiple eccentric disks and arc-shaped protrusions are arranged in a circular shape with equal distances about the vertical center line of the turntable.

[0013] As a preferred solution of the burner nozzle amplitude adjustment mechanism of the present invention, the roller and the eccentric disk are arranged in the same vertical plane, and the plurality of arc-shaped protrusions are arranged in a one-to-one correspondence with the eccentric disk.

[0015] The beneficial effects of the burner nozzle amplitude adjustment mechanism of the present invention are as follows: when the swing amplitude of the nozzle is increased, the arc-shaped protrusion contacts the eccentric disk by rotating the circular ring, thereby driving the eccentric disk to deflect, and multiple eccentric disks expand outward after deflection, so that the diameter formed is larger than the diameter of the turntable, thereby realizing amplitude adjustment and achieving the effect of rapid adjustment at the same time, the chain is set on the sprocket, and then driven by setting a motor. When the motor drives the sprocket to rotate, the turntable follows the rotation, so that the outer side of the eccentric disk contacts the roller, and then drives the roller to rotate, and at the same time, drives the nozzle to swing up and down. After the deflection amplitude of the eccentric disk is adjusted by rotating the circular ring, the splint is pressed on the surface of the circular ring by flipping, and then the threaded anti-disconnection buckle is rotated to make the threaded anti-disconnection buckle rotate and pressurize the splint, so that the splint presses the circular ring, thereby fixing the circular ring and preventing the circular ring from loosening.

[0016] In view of the fact that in actual use, there is still the problem of not being strong enough.

[0022] The beneficial effects of the locking device of the present invention are as follows: the clamping ring is aligned with the positioning rod and then inserted into the clip, and the conical ring is moved toward the conical end of the clip by rotating the nut, and pressure is applied to the clip at the same time, so that multiple clips clamp the positioning rod. At the same time, the threaded barrel is rotated and displaced to tightly fix it with the eccentric disk, thereby playing a double fixing role. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1-Figure 2 , is the first embodiment of the present utility model, which provides a burner nozzle amplitude adjustment mechanism, including:

[0034] The nozzle mechanism 100 includes a nozzle 101, a crossbar 102 provided on one side of the nozzle 101, and a roller 103 provided on the nozzle 101 for rotating to reduce wear;

[0035] The main body 200 includes a burner nozzle 201, an amplifying component 202 provided on one side of the burner nozzle 201, the burner nozzle 201 and the nozzle 101 are hingedly connected, and an adjusting component 203 provided on the amplifying component 202 for rapid adjustment.

[0036] Furthermore, the amplification component 202 includes a turntable 202a, which is rotatably connected to one side of the burner nozzle 201. One side of the turntable 202a is rotatably connected to an eccentric disk 202b. An arc-shaped groove 202c is provided on the inner side of the eccentric disk 202b. A positioning rod 202d is provided on the inner side of the arc-shaped groove 202c. The positioning rod 202d is fixedly installed on one side of the turntable 202a, and the eccentric disk 202b is positioned by sliding the positioning rod 202d on the inner side of the arc-shaped groove 202c.

[0037] Furthermore, the adjusting component 203 includes a hollow tube 203a, which is fixedly mounted on one side of the turntable 202a. A sprocket 203b is provided at one end of the hollow tube 203a. Through the arrangement of the sprocket 203b, a chain can be set on the outside of the sprocket 203b, and then a motor is installed to connect the chain for driving. A ring 203c is rotatably connected to the outside of the hollow tube 203a. An arc-shaped protrusion 203d is provided on the outside of the ring 203c. The number of the eccentric disk 202b and the arc-shaped protrusion 203d is set to multiple, and multiple eccentric disks 202b and arc-shaped protrusions 203d are connected. The protrusions 203d are arranged in a circular shape with equal distances about the vertical center line of the turntable 202a. The roller 103 and the eccentric disk 202b are arranged in the same vertical plane. Through the arrangement of the same vertical plane, when multiple eccentric disks 202b increase their diameters after deflection, the roller 103 will increase the swing amplitude of the nozzle 101 when contacting the eccentric disk 202b. The arc-shaped protrusions 203d and the eccentric disk 202b are arranged in a one-to-one correspondence. Through the one-to-one correspondence, when the ring 203c is rotated, the arc-shaped protrusions 203d will simultaneously drive the deflection movement of multiple eccentric disks 202b.

[0038] Usage process: When it is necessary to increase the swing amplitude of the nozzle 101, the circular ring 203c is rotated so that the arc-shaped protrusion 203d contacts the eccentric disk 202b, thereby driving the eccentric disk 202b to deflect. After the multiple eccentric disks 202b are deflected, they expand outward, thereby forming a diameter larger than the diameter of the turntable 202a. The chain is placed on the sprocket 203b, and then a motor drive is set. When the motor drives the sprocket 203b to rotate, the turntable 202a follows the rotation, so that the outer side of the eccentric disk 202b contacts the roller 103, thereby driving the roller 103 to rotate, and at the same time, driving the nozzle 101 to swing up and down.

[0039] Example 2

[0040] Reference Figure 2-Figure 3 , which is the second embodiment of the present invention, further provides a fixing mechanism 300; comprising a base 301, a splint 302 provided on the inner side of the base 301, the splint 302 and the base 301 being hingedly provided

[0041] Furthermore, a transverse groove 303 is provided on the inner side of the splint 302, and a threaded rod 304 is provided on the inner side of the transverse groove 303. The threaded rod 304 is fixedly mounted on the inner bottom of the base 301, and the outer side of the threaded rod 304 is threadedly connected to a threaded anti-disconnection buckle 305. The cross-sectional area of ​​the bottom end port of the transverse groove 303 is smaller than the cross-sectional area of ​​the bottom end port of the threaded anti-disconnection buckle 305. Through such an arrangement, when the threaded anti-disconnection buckle 305 and the transverse groove 303 remain in a transverse state, when the splint 302 is flipped over to tighten the ring 203c, it can pass through the threaded anti-disconnection buckle 305. When the threaded anti-disconnection buckle 305 is rotated to a vertical state, 302c is stuck and cannot be flipped up.

[0042] Usage process: After rotating the ring 203c to adjust the deflection amplitude of the eccentric disk 202b, flip the splint 302 to press on the surface of the ring 203c, and then rotate the threaded anti-dropout buckle 305 to make the threaded anti-dropout buckle 305 rotate to press the splint 302, so that the splint 302 presses the ring 203c, thereby fixing the ring 203c to prevent the ring 203c from loosening.

[0046] Furthermore, the number of clips 403 is set to be multiple, and a circular aperture is formed when multiple clips 403 are fitted together. The clip 403 is made of elastic material, and one end of the clip 403 is conically set. The outer thread of the threaded barrel 402 is connected to a nut 404, and a conical ring 405 is provided on the inner side of the nut 404, which is adapted to the conical end of the clip 403.

[0047] Usage process: Align the clamping ring 401 with the positioning rod 202d, then insert it into the clip 403, and rotate the nut 404 to move the conical ring 405 toward the conical end of the clip 403. At the same time, apply pressure to the clip 403 so that multiple clips 403 clamp the positioning rod 202d. At the same time, use the threaded barrel 402 to rotate and displace, so that it is tightly fixed with the eccentric disk 202b, playing a double fixing role.
