[0031] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0032] Please also read Figures 1 to 3 The dust collecting duct spraying device provided by the utility model is now described. The dust collecting duct spraying device comprises a plurality of spraying assemblies 10 arranged at intervals along the axial direction of the dust collecting duct 60, the spraying assembly 10 comprises a water inlet pipe 20, a hanger 30, a fixing ring 40 and a spraying pipe 50, one end of the water inlet pipe 20 extends into the dust collecting duct 60; the two ends of the hanger 30 are fixedly connected to the inner wall of the dust collecting duct 60; a plurality of fixing rings 40 are provided along the extension direction of the hanger 30; the spraying pipe 50 penetrates the plurality of fixing rings 40 and is connected to the water inlet pipe 20, and a spray head 51 is provided on the spraying pipe 50.

[0033] As a specific arrangement, the water inlet pipe 20 is arranged vertically, the hanger 30 is arranged horizontally, the spray pipe 50 is parallel to the extension direction of the hanger 30, and is perpendicular to the axial direction of the water inlet pipe 20 and the dust collecting pipe 60 respectively.

[0034] Compared with the prior art, the spray device in the dust collecting duct provided in the present embodiment can be achieved by arranging multiple spray components 10 in the dust collecting duct 60. The spray components 10 do not hinder the passage of smoke and can be opened regularly. Cleaning of the dust collecting duct 60 is achieved by spraying cleaning water inside the dust collecting duct 60 through the nozzle 51. Moreover, since multiple spray components 10 are provided, the nozzle 51 on each spray component 10 can also flush the adjacent spray components 10 when spraying cleaning water. The spray device in the dust collecting duct of the utility model can automatically clean the dust collecting duct 60 regularly, replace manual labor, reduce labor intensity, and save labor costs.

[0035] In order to achieve water reuse, the dust collecting duct 60 can be gradually tilted downward in the direction close to the water bath dust collector. During the cleaning process, the cleaning water can gradually flow into the water bath dust collector along the inclination of the dust collecting duct 60 to achieve recycling and avoid clogging caused by the cleaning water being retained in the dust collecting duct 60.

[0036] In some embodiments, a specific implementation of the nozzle 51 can be as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 The nozzle 51 is a spiral nozzle. The spiral nozzle has a smooth flow channel, which can minimize liquid blockage, so that the liquid reaches the maximum flow rate on a pipe of a given size, thereby improving the cleaning effect.

[0037] In some embodiments, an improved implementation of the nozzle 51 can be as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 The bottom of the nozzle 51 is tilted toward the smoke outlet side. A hole is made on the spray pipe 50, and then the nozzle 51 is installed in the empty position. When making the hole, it is necessary to ensure that the axial direction of the hole is gradually tilted toward the smoke outlet side from top to bottom, so that the bottom of the nozzle 51 can be tilted toward the smoke outlet side after being installed in the hole.

[0038] In this embodiment, the installation of the nozzle 51 can prevent dust from clogging the nozzle 51 and affecting its normal use during the continuous passage of smoke, reduce the number of times the nozzle 51 is unclogged, and extend the service life of the nozzle 51.

[0039] In some embodiments, an improved implementation of the above-mentioned hanger 30 can be adopted as follows Figure 2 See the structure shown. Figure 2 The bottom of the hanger 30 is provided with a plurality of suspension rods 31, and a fixing ring 40 is fixedly connected to each suspension rod 31, so that the spray pipe 50 and the hanger 30 are arranged at intervals. When the nozzle 51 is working, the water impact will cause the spray pipe 50 to vibrate to a certain extent. By setting the suspension rods 31 to separate the spray pipe 50 from the hanger 30 in the vertical direction, it is possible to prevent the connection between the hanger 30 and the inner wall of the dust collecting pipe 60 from loosening when the spray pipe 50 sprays and vibrates; and by setting the suspension rods 31, and the fixing rings 40 and the suspension rods 31 are in one-to-one correspondence, it is convenient to determine the installation position of the fixing ring 40 according to the position of the suspension rods 31, which is convenient for assembly and simple to use.

[0040] In some embodiments, a specific implementation of the fixing ring 40 can be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3The fixing ring 40 is a U-shaped rod, and the hanging rod 31 is provided with a through hole for the end of the fixing ring 40 to pass through. A fastening nut 41 is also screwed on the end of each fixing ring 40, and the fastening nut 41 abuts against the side of the hanging rod 31 away from the spray pipe 50. After the fixing ring 40 is installed on the hanging rod 31, the fastening nut 41 is matched with the end of the fixing ring 40. After the spray pipe 50 passes through the fixing ring 40, the fixing ring 40 is gradually tightened by gradually tightening the fastening nut 41, so that the fixing ring 40 gradually tightens the spray pipe 50, and the spray pipe 50 is fixed, which is convenient for installation.

[0041] In some embodiments, a specific matching method between the suspension rod 31 and the hanger 30 can be as follows: Figure 1 See the structure shown. Figure 1 The suspension rod 31 is screwed to the hanger 30. The screw connection between the suspension rod 31 and the hanger 30 facilitates the disassembly of the suspension rod 31, and the same number of suspension rods 31 can be installed according to the number of fixing rings 40, which is more flexible to use.

[0042] In some embodiments, a deformation matching mode of the suspension rod 31 and the hanger 30 can be adopted as follows: Figure 3 See the structure shown. Figure 3 The bottom of the hanger 30 is provided with a slide groove 32 parallel to the axial direction of the spray pipe 50, and the suspension rod 31 slides in cooperation with the slide groove 32. By sliding the hanger 30 on the slide groove 32, the position of the fixing ring 40 can be changed, so that the fixing ring 40 avoids the nozzle 51 on the spray pipe 50, avoiding blocking individual nozzles 51 and affecting the spray cleaning process.

[0043] In some embodiments, an improved implementation of the suspension rod 31 can be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The suspension rod 31 is provided with an adjustment plate 33, which is slidably matched with the suspension rod 31 in the up-down direction, and the fixing ring 40 is fixedly connected to the adjustment plate 33. By adjusting the adjustment plate 33 up and down, the distance between the spray pipe 50 and the inner wall of the dust collecting pipe 60 can be adjusted, thereby adjusting the spray range of the spray head 51. The installation is convenient and can be adaptively adjusted according to the inner diameter size of the dust collecting pipe 60.

[0044] In some embodiments, an improved embodiment of the fixing ring 40 can be as follows: Figure 3 See the structure shown. Figure 3 The inner circumference of the fixing ring 40 is provided with a buffer pad 42. Since the fixing ring 40 needs to fix the spray pipe 50, by providing the buffer pad 42 (which can be a sponge pad or a rubber pad) on the inner circumference, the spray pipe 50 can be prevented from being squeezed, bent, cracked, etc.

[0045] In some embodiments, a specific connection method between the hanger 30 and the dust collecting duct 60 can be as follows: Figure 1 See the structure shown. Figure 1 The hanger 30 is welded to the inner wall of the dust collecting duct 60. The hanger 30 is fixed by full welding, which has better firmness and is convenient for operation.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
