Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle technology, specifically to a high-efficiency secondary air nozzle device. Background Technology
[0002] In waste-to-energy incineration, the primary and secondary air in the pulverized coal combustion nozzles have different functions and roles. The primary air is mainly responsible for conveying pulverized coal into the furnace and providing the oxygen required for initial combustion; while the secondary air is to further supplement the oxygen required for combustion, adjust the combustion state, and ensure that the pulverized coal is fully burned.
[0003] A nozzle is a device that can accelerate, disperse, spray, or shape fluids (such as liquids, gases, etc.) into specific shapes and directions. There are many types of nozzles, including high-efficiency secondary air nozzle devices, which are devices that spray secondary air out with high efficiency and in a specific manner.
[0004] When existing high-efficiency secondary air nozzle devices are in use, dust, impurities, or precipitates generated during the process may be carried in the secondary air. These substances tend to accumulate at the nozzle's outlet end, causing blockage. Blockage reduces the spray pressure and affects the spray effect. Therefore, it is necessary to propose a high-efficiency nozzle device with auxiliary filtration to prevent precipitates from accumulating at the nozzle's outlet end. Utility Model Content
[0005] The purpose of this utility model is to provide a high-efficiency secondary air nozzle device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0007] Nozzle assembly, the nozzle assembly including a connecting pipe;
[0008] The removable filter assembly includes a plug-in block, a filter plate, and a limiting ring. The plug-in block is inserted into one side of the middle section of the connecting pipe, the filter plate is fixed to the bottom end of the plug-in block and snapped into the inside of the connecting pipe, and the limiting ring is threaded to one side of the middle section of the connecting pipe and located outside the plug-in block.
[0009] Furthermore, the connecting pipe has a connecting hole at the insertion point with the plug block, and a plug rod is fixedly connected to the bottom end of the filter plate.
[0010] Furthermore, the bottom end of the plug rod extends to the bottom end of the inner side of the connecting tube, and a limiting groove is formed in the connecting tube at the connection with the plug rod.
[0011] Furthermore, the nozzle assembly also includes a connecting pipe and a spray end; the connecting pipe is fixed to one end of the connecting pipe, and the spray end is fixed to the outer end of the connecting pipe.
[0012] Furthermore, it also includes auxiliary limiting components;
[0013] The auxiliary limiting component includes a slot, a slider, and a connecting rod; the slot is located on both sides below the connection between the connecting pipe and the coupling pipe, the slider is slidably connected to the inside of the slot, and the connecting rod is fixed to the outer end of the slider.
[0014] Furthermore, a limiting groove is provided on the inner side of the outer end of the connecting rod, and a limiting ring is engaged between the inner sides of the limiting groove. The limiting ring is sleeved with the connecting pipe and the connecting tube.

Magnetic areas are fixedly connected to the opposite ends of the fixing ring and the limiting ring, and the two ends of the limiting ring are attracted to the magnetic areas.
[0016] This utility model has the following beneficial effects:
[0017] This invention, by setting up an easy-to-remove filter assembly, allows the filter plate to filter newly precipitated substances, thereby preventing the precipitates from accumulating at the nozzle's outlet end. At the same time, rotating the limiting ring exposes the insertion block to the outside, allowing the insertion block to be removed and the filter plate to leave the connecting pipe, thus facilitating the cleaning of the filter plate after use and preventing clogging that could affect the nozzle's spray pressure and spray effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figures 1-4 As shown, this utility model is a high-efficiency secondary air nozzle device, comprising:
[0029] A nozzle assembly, which includes a connecting pipe 11;
[0030] The nozzle assembly also includes a connecting pipe 12 and a spray end 13; the connecting pipe 12 is fixed to one end of the connecting pipe 11, and the spray end 13 is fixed to the outer end of the connecting pipe 12.
[0031] Connecting pipe 11 is used to connect to connecting pipe 12, connecting pipe 12 is used to connect to ejector end 13, and ejector end 13 is used for fluid injection.
[0032] The removable filter assembly includes a plug-in block 22, a filter plate 23, and a limiting ring 24. The plug-in block 22 is inserted into one side of the middle section of the connecting pipe 11, the filter plate 23 is fixed to the bottom end of the plug-in block 22 and snapped into the inside of the connecting pipe 11, and the limiting ring 24 is threaded to one side of the middle section of the connecting pipe 11 and is located around the plug-in block 22.
[0033] The plug-in block 22 is used to connect the filter plate 23 and the connecting pipe 11. The filter plate 23 filters the fluid in the connecting pipe 11. The limiting ring 24 limits the plug-in block 22 after plugging in, preventing the gap at the plug-in joint from leaking outward.
[0034] The connecting pipe 11 has a connecting hole 21 at the insertion point with the plug block 22, and the bottom end of the filter plate 23 is fixedly connected to the plug rod 25;
[0035] The bottom end of the plug rod 25 extends to the bottom end of the inner side of the connecting tube 11, and the connecting tube 11 has a limit groove 26 at the connection with the plug rod 25;
[0036] The connecting hole 21 is used for the connection between the plug block 22 and the connecting pipe 11. The plug rod 25 and the limiting groove 26 are used for the connection between the filter plate 23 and the connecting pipe 11, thereby preventing the plug block 22 from rotating when the limiting ring 24 rotates. The filter plate 23 is inserted into the connecting pipe 11 through the connecting hole 21, so that the plug rod 25 is inserted into the limiting groove 26, and the plug block 22 is engaged with the connecting hole 21.
[0037] Working principle: When the component is not in use, the connection hole 21 is empty. When the component is in use, hold the filter plate 23 by hand and insert it into the connecting tube 11 through the connection hole 21, so that the insertion rod 25 is inserted into the limiting groove 26, and then the insertion block 22 is engaged with the connection hole 21. Then push the limiting ring 24 so that the limiting ring 24 moves to one end of the connecting tube 11. At this time, rotate the limiting ring 24 so that the limiting ring 24 rotates to the outside of the insertion block 22 through the thread, so that the limiting ring 24 limits the insertion of the filter plate 23 and the insertion block 22. When the nozzle is used, the filter plate 23 filters the new precipitate, thereby preventing the precipitate from accumulating at the nozzle outlet 13. When the filter plate 23 needs to be cleaned, rotate the limiting ring 24 so that the insertion block 22 is exposed to the outside, remove the insertion block 22, so that the filter plate 23 leaves the connecting tube 11, thereby facilitating the cleaning of the filter plate 23 after use.
[0038] Please see Figures 1-2 - Figure 5 As shown, this embodiment, based on the above embodiment, further includes:
[0039] Auxiliary limit components;
[0040] The auxiliary limiting component includes a slot 31, a slider 32, and a connecting rod 33; the slot 31 is opened on both sides below the connection between the connecting pipe 11 and the connecting pipe 12, the slider 32 is slidably connected to the inner side of the slot 31, and the connecting rod 33 is fixed to the outer end of the slider 32.
[0041] The slot 31 is used for connecting and moving the slider 32, the slider 32 is used for connecting the connecting rod 33, and the connecting rod 33 is used to limit the opening of the slot 34.
[0042] A limiting groove 34 is provided on the inner side of the outer end of the connecting rod 33, and a limiting ring 35 is snapped between the inner sides of the limiting groove 34. The limiting ring 35 is sleeved with the connecting pipe 11 and the connecting pipe 12.
[0043] A fixing ring 36 is fixedly connected to the middle section of the connecting pipe 12 and is located at the edge of the slot 31. A magnetic area 37 is fixedly connected to the opposite ends of the fixing ring 36 and the limiting ring 35. The two ends of the limiting ring 24 are attracted to the magnetic area 37.
[0044] The limiting groove 34 is used to connect the limiting ring 35 and control the rotation range of the limiting ring 35. The limiting ring 35 and the fixed ring 36 are used to limit the limiting ring 24 when it is idle. The magnetic area 37 limits the limiting ring 24 when it is idle by magnetic force, preventing the limiting ring 24 from moving arbitrarily on the connecting pipe 11 and the connecting pipe 12.
[0045] Working principle: When the component is not in use, the limiting ring 24 is in a restricted state. At this time, the limiting ring 35 is located on the connecting pipe 12, and the two ends of the limiting ring 24 are attracted to the magnetic areas 37 of the limiting ring 35 and the fixing ring 36, respectively. This allows the magnetic areas 37 to limit the idle limiting ring 24 through magnetic force. When the limiting ring 24 is in use, the limiting ring 24 is pushed by hand. The pushing force pushes the slider 32 in the slot 31 through the limiting ring 24 and the limiting ring 35. This causes the limiting ring 24 to push the limiting ring 35 to move towards the plug-in block 22 through the slider 32. When the limiting ring 24 rotates to the periphery of the plug-in block 22, the limiting ring 24 drives the limiting ring 35 to rotate in the limiting groove 34 through the magnetic area 37. This causes the limiting ring 24 to rotate and move, driving the limiting ring 35 to move together, thereby achieving the limitation and use of the limiting ring 24.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
