Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration equipment, in particular to a low-nitrogen combustion device for a garbage incineration plant. Background Art

[0002] A waste incineration plant is a facility that carries out high-temperature incineration of municipal solid waste (usually domestic waste, industrial waste, etc.). Its main purpose is to reduce the volume of waste, disinfect it, and convert it into energy by incinerating it, ultimately achieving multiple goals such as reducing the burden of waste disposal, reducing environmental pollution, and recovering energy. The low-nitrogen combustion device currently used in waste incineration plants includes a low-nitrogen burner and a bottom support frame. The structure of the low-nitrogen burner usually includes a base and a flamethrower. The base is installed on the outside of the incinerator, while the flamethrower is installed inside the incinerator for burning materials. The traditional low-nitrogen burner is usually connected to the bottom bracket in a fixed manner. This connection method means that if the burner or bracket needs to be repaired or replaced, the disassembly and reinstallation process is relatively cumbersome. At the same time, during the installation process, due to manufacturing and installation errors, the fixed connection will cause the docking of the burner and the bracket to be not completely accurate, which in turn affects the working state of the burner. Utility Model Content

This connection method means that if the burner or bracket requires repair or replacement, the removal and reinstallation process is cumbersome. Furthermore, during installation, due to manufacturing and installation errors, the fixed connection can lead to inaccurate alignment between the burner and bracket, which in turn affects the burner's operating performance. The present utility model proposes a low-nitrogen combustion device for waste incineration plants.

[0025] Example

[0026] like Figures 1 to 5 As shown, the utility model proposes a low-nitrogen combustion device for a waste incineration plant, comprising a low-nitrogen burner 1 and a fixed base plate 2 installed at the bottom end of the low-nitrogen burner 1, and also comprising: a mounting base plate 3, arranged directly below the fixed base plate 2; a cylinder 7 fixedly connected to the upper surface of the mounting base plate 3 for driving the low-nitrogen burner 1 to move up and down, the piston rod of the cylinder 7 being fixedly connected to the fixed base plate 2; a plurality of support rod mechanisms, arranged in the middle of the fixed base plate 2 and the mounting base plate 3, and linked to the telescopic rod of the cylinder 7 for adjustment; a plurality of card and disassembly mechanisms fixedly mounted on the upper surface of the mounting base plate 3 and correspondingly plugged into the support rod mechanisms.

[0027] Furthermore, the support rod mechanism includes a movably connected bottom tube 5 and a telescopic rod 6. One end of the bottom tube 5 is provided with a first chamber 51 movably connected to the telescopic rod 6. The other end of the bottom tube 5 is fixedly provided with a socket 8. The upper surface of the mounting base 3 is fixedly connected with a plurality of supports 4 corresponding to the sockets 8. The end of the telescopic rod 6 away from the bottom tube 5 is fixedly connected with a top plate 61. The top plate 61 increases the contact area between the top end of the bottom tube 5 and the fixed bottom plate 2, so that the bottom tube 5 is more stable when supporting the fixed bottom plate 2.

[0028] The first chamber 51 is provided with a push-pull spring 59, which makes the telescopic rod 6 in the first chamber 51 tightly against the lower surface of the fixed base plate 2 in any state, and the push-pull spring 59 is in normal state. Figure 4One end of the push-pull spring 59 is fixedly connected to the inner wall of the first chamber 51 , and the other end of the push-pull spring 59 is fixedly connected to the end of the telescopic rod 6 away from the top plate 61 .

[0029] Secondly, the card disassembly mechanism includes a plurality of positioning blocks 41 fixedly connected to the upper surface of the support 4, and a plurality of card holes 81 for inserting the positioning blocks 41 are provided on the card seat 8, wherein a pair of the inner walls of the positioning blocks 41 are provided with card grooves 42, and the end of the bottom tube 5 close to the card seat 8 is slidably connected with a pair of card buttons 57 inserted into the card groove 42, and the end of the card button 57 away from the driving plate 54 is set as a spherical plug, which makes it easier and more convenient to insert the card button 57 into the card groove 42.

[0030] Furthermore, the latching and disassembling mechanism also includes a second chamber 52 formed within the other end of the bottom barrel 5. A pair of pressing blocks 53 are slidably connected to the end of the bottom barrel 5 near the latch seat 8. The ends of the pressing blocks 53 inserted into the bottom barrel 5 are fixedly connected to a driving plate 54. Each driving plate 54 has a pair of limiting grooves 58. A pair of limiting support rods 56 are fixedly connected to the inner wall of the bottom barrel 5, which engage the corresponding limiting grooves 58. A pair of return springs 55 are fixedly connected to the middle of the driving plate 54. The return springs 55 automatically return the pressing blocks 53 to their original positions after being released, allowing for reuse next time. The bottom end of the driving plate 54 is fixedly connected to a corresponding locking button 57 below.

[0031] In this embodiment, when it is necessary to use a low nitrogen combustion device in a waste incineration plant, such as Figure 1As shown, the cylinder 7 in the middle of the fixed base plate 2 and the mounting base plate 3 is first activated. The piston rod of the cylinder 7 drives the low-nitrogen burner 1 on the fixed base plate 2 to move up and down. At the same time, the multiple telescopic rods 6 at the bottom of the fixed base plate 2 are pushed by the elastic thrust of the push-pull spring 59 in the first chamber 51, so that the top plate 61 of the top of the telescopic rods 6 is always against the lower surface of the fixed base plate 2. When the bottom barrel 5 and the telescopic rods 6 need to be removed from the bottom of the fixed base plate 2 for repair or damage, they only need to pinch the pair of pressing blocks 53 simultaneously. The pressing blocks 53 drive the corresponding driving plates 54 to move, and the bottom ends of the driving plates 54 drive the corresponding locking buttons 57 to retract into the second chamber 52. At this time, the bottom barrel 5 is pushed upward again, so that more of the telescopic rods 6 are inserted into the first chamber 51. Then, the base 8 at the bottom of the bottom barrel 5 is disengaged from the support 4. Finally, the bottom barrel 5 and the telescopic rods 6 can be removed from the middle of the fixed base plate 2 and the mounting base plate 3. No major disassembly is required. Simply remove the base tube 5 and telescopic rod 6 one by one from the middle of the fixed base plate 2 and the mounting base plate 3 and install them one by one to complete the replacement of all base tubes 5 and telescopic rods 6. This is simple and easy to operate. When the base tube 5 and telescopic rod 6 need to be installed on the corresponding support 4, simply snap the base 8 at the bottom of the corresponding base tube 5 onto the support 4 so that the positioning plug 41 is inserted into the corresponding locking hole 81. Then, press the pressing block 53 to retract it into the second chamber 52 until the support 4 and the plug-in connection between the plug-in block 8 are completed. The pair of pressing blocks 53 can then be released. At this time, the corresponding locking button 57 can slide out of the second chamber 52 and insert into the slot 42 on the positioning plug 41, completing the plug-in connection between the support 4 and the plug-in block 8.
