Description

Technical Field

[0001] The utility model relates to the field of low-nitrogen burners, in particular to a spliced ​​low-nitrogen burner. Background Art

[0002] The burner is an important equipment on industrial oil boilers and gas boilers. It ensures the stable ignition and complete combustion of the fuel. Therefore, to suppress the generation of NOx, we must start with the burner. The spliced ​​low-nitrogen burner is a device that adds a blower, induced draft fan, inverter, control valve and multiple circuits to the traditional burner to allow clean energy and burner operation to provide more efficient thermal energy for the boiler.

[0003] Most of the existing spliced ​​low-nitrogen burners connect the connecting pipe to the flange at the front end of the low-nitrogen burner by using a handheld bolt assembly. This process increases the connection burden on the workers, and during the use of the low-nitrogen burner, the common connecting pipe will shake between the flange, which can easily lead to looseness between the connecting pipe and the flange over a long period of time, thus affecting the stable operation of the low-nitrogen burner.

[0004] In summary, the above structure increases the connection burden on the workers during the installation process, and is very likely to cause loosening between the connecting pipe and the flange over a long period of time, thereby affecting the stable operation of the low-nitrogen burner. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a spliced ​​low-nitrogen burner to solve the technical problem that the connection burden of the workers is increased during the installation process, and the connecting pipe and the flange are easily loosened over a long period of time, thereby affecting the stable operation of the low-nitrogen burner.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a spliced ​​low-nitrogen burner, comprising a burner body, a connecting pipe and a flange, a first latch and a second latch being detachably provided on the burner body and passing through the flange, a tooth block being provided at the bottom of the first latch, and a fixed gear being meshed at the bottom of the tooth block, a threaded rod being connected to the bottom of the fixed gear through a transmission mechanism, a threaded sleeve being slidably provided on the outer wall of the threaded rod, a horizontal slot for inserting the threaded sleeve being provided on the second latch, a limit rod being slidably provided on the burner body, and a vertical slot for inserting the limit rod being provided on the first latch.

[0007] By adopting the above technical solution, the first pin and the second pin are inserted into the burner body through the flange. During the insertion of the first pin, the tooth block at the bottom will drive the fixed gear to rotate, and the threaded rod will be driven to rotate under the action of the transmission mechanism, thereby driving the threaded sleeve to be inserted into the horizontal slot of the second pin. At the same time, the limit rod will be inserted into the vertical slot of the first pin, thereby completing the limiting work of the first pin. In this process, there is no need to use the bolt assembly, which reduces the burden of disassembly and assembly of subsequent staff.

[0008] The utility model is further configured that one end of the fixed gear is connected to a transmission mechanism, and the other end of the transmission mechanism is connected to a threaded rod.

[0009] By adopting the above technical solution, when the fixed gear rotates under the action of the tooth block, it will drive the transmission mechanism to rotate. During this process, the transmission mechanism will drive the threaded rod at the other end to rotate, thereby achieving that when the fixed gear rotates, the threaded rod will also rotate.

[0010] The utility model is further configured that one end of the threaded sleeve and the limiting rod are both configured in a conical frustum shape.

[0011] By adopting the above technical solution, the conical truncated cone-shaped setting makes it easier for the threaded sleeve and the limiting rod to be inserted into the second latch and the first latch respectively, and in this process, the stability of the overall limiting is further improved to prevent it from getting stuck.

[0012] The utility model is further configured that the transmission mechanism includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the driving disk is connected to the fixed gear, and one end of the driven disk is connected to the threaded rod, and the diameter of the driving disk on the transmission mechanism is larger than the diameter of the driven disk.

[0013] By adopting the above technical solution, the active disk at one end will be driven to rotate during the rotation of the fixed gear, and the driven disk on one side will be driven to rotate by the action of the transmission belt, so that the threaded rod can be driven to rotate under the action of the driven disk. Since the diameter of the active disk on the transmission mechanism is larger than the diameter of the driven disk, when the fixed gear drives the active disk to rotate several times, the driven disk will drive the threaded rod to rotate several times, thereby facilitating the rapid adjustment of the sliding of the threaded sleeve on the outer wall of the threaded rod.

[0014] The utility model is further configured such that the second latch pin, the first latch pin, the threaded sleeve and the limiting rod are arranged in a rough shape.

[0015] By adopting the above technical solution, the rough setting prevents the second latch and the first latch from shaking and slipping off during the operation of the burner body, further improving the stability of the overall limit.

[0016] The utility model is further configured that the burner body is provided with an opening for inserting the first latch and the second latch, and one end of the opening is arranged in an arc shape.

[0017] By adopting the above technical solution, the arc-shaped setting at one end of the opening plays a guiding role for the first latch and the second latch, making it easier for the first latch and the second latch to be directly inserted into the burner body.

[0018] The utility model is further configured that the tooth block is located at the bottom of the first latch as a local configuration.

[0019] By adopting the above technical solution, the locally arranged tooth blocks facilitate to ensure the number of revolutions of the fixed gear each time, so that no matter how far the first latch is displaced inwards, the fixed gear will only be driven to rotate a certain number of revolutions.

[0020] The utility model is further configured such that outer walls of the first latch pin, the second latch pin and the limiting rod are provided with rough surfaces.

[0021] By adopting the above technical solution, the rough surface is provided to facilitate improving the sliding friction between the first latch, the second latch, the limit rod and the hands of the staff, thereby preventing the hands of the staff from slipping during the disassembly of the connecting pipe.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model provides a limiting rod at the top of the burner body, and the first pin and the second pin penetrate the flange and are inserted into the burner body. During the insertion of the first pin, the tooth block at the bottom will drive the fixed gear to rotate, and the threaded rod will be driven to rotate under the action of the transmission mechanism, so as to drive the threaded sleeve to be inserted into the horizontal slot of the second pin. In this process, the limiting work of the second pin is completed, and the limiting rod will be inserted into the vertical slot of the first pin, thereby completing the limiting work of the first pin. In this process, there is no need to use a bolt assembly, which reduces the disassembly and assembly burden of subsequent staff, and at the same time, the flange and the connecting pipe will not loosen due to vibration, thereby ensuring the stable operation of the low-nitrogen burner.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A spliced ​​low nitrogen burner, such as Figure 1-Figure 4As shown, it includes a burner body 1, a connecting pipe 4, a flange 6, a transmission mechanism 7 and a limiting mechanism. A flange 6 is provided at one end of the burner body 1. Then the staff clamps the connecting pipe 4 on the flange 6, firstly inserts the second latch 5 through the flange 6 into the burner body 1, and then inserts the first latch 3 through the flange 6 into the burner body 1. Since a tooth block 10 is provided at the bottom of the first latch 3, and a fixed gear 9 is meshed at the bottom of the tooth block 10, during the insertion of the first latch 3, the tooth block 10 will drive the fixed gear 9 at the bottom to rotate, and a transmission mechanism 7 is connected to one end of the fixed gear 9, and a threaded rod 13 is connected to the other end of the transmission mechanism 7. When the fixed gear 9 rotates under the action of the tooth block 10, it will drive the transmission mechanism 7 to rotate. In this process, the transmission mechanism 7 will drive the threaded rod 13 at the other end to rotate, thereby achieving When the fixed gear 9 rotates, the threaded rod 13 will also rotate accordingly. A threaded sleeve 12 is slidably provided on the outer wall of the threaded rod 13. The second pin 5 is provided with a horizontal slot 11 for the threaded sleeve 12 to be inserted. The threaded rod 13 is driven to rotate under the action of the transmission mechanism 7, thereby driving the threaded sleeve 12 to be inserted into the horizontal slot 11 of the second pin 5. In this process, the second pin 5 is limited. Similarly, a limit rod 2 is slidably provided on the burner body 1, and a vertical slot 8 for the limit rod 2 to be inserted is provided on the first pin 3. The subsequent limit rod 2 will be inserted into the vertical slot 8 of the first pin 3, thereby completing the limiting work of the first pin 3. In this process, there is no need to use a bolt assembly, which reduces the burden of disassembly and assembly of subsequent staff. At the same time, the flange 6 and the connecting pipe 4 will not loosen due to vibration, thereby ensuring the stable operation of the low-nitrogen burner.

[0033] See also Figure 3 The threaded sleeve 12 and one end of the limiting rod 2 are both in a conical cone shape, which makes it easier for the threaded sleeve 12 and the limiting rod 2 to be inserted into the second latch 5 and the first latch 3 respectively. In this process, the stability of the overall limit is further improved to prevent it from getting stuck.

[0034] Embodiment 2

[0035] like Figure 2A spliced ​​low-nitrogen burner is shown, and its overall structure is similar to that of Example 1, wherein a transmission mechanism 7 includes an active disk, a transmission belt and a driven disk, wherein the active disk and the driven disk are connected by a transmission belt, one end of the active disk is connected to a fixed gear 9, and one end of the driven disk is connected to a threaded rod 13, during the rotation of the fixed gear 9, the active disk at one end is driven to rotate, and the driven disk on one side is driven to rotate by the action of the transmission belt, thereby driving the threaded rod 13 to rotate under the action of the driven disk, since the diameter of the active disk on the transmission mechanism is larger than the diameter of the driven disk, when the fixed gear 9 drives the active disk to rotate several times, the driven disk will drive the threaded rod 13 to rotate several times, thereby facilitating the rapid adjustment of the sliding of the threaded sleeve 12 on the outer wall of the threaded rod 13.

[0036] The working principle of the utility model is as follows: when in use, one end of the connecting pipe 4 is clamped to the flange 6, and then the first pin 3 and the second pin 5 are inserted through the flange 6 into the burner body 1. First, the second pin 5 is inserted into the burner body 1, and then the first pin 3 is inserted. During the sliding of the first pin 3, the tooth block 10 at the bottom will drive the fixed gear 9 to rotate, thereby driving the transmission mechanism 7 to rotate. Since one end of the transmission mechanism 7 is connected to a threaded rod 13, the threaded rod 13 will drive the threaded sleeve 12 to slide to one side, so that the threaded sleeve 12 is inserted into the horizontal slot 11 of the second pin 5, and then inserted into the vertical slot 8 of the first pin 3 under the action of the limiting rod 2. In this process, there is no need for the bolt assembly to limit it, which further reduces the overall disassembly and assembly work intensity.

[0037] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
