Description

Technical Field

[0001] The utility model relates to the technical field of air duct structures, in particular to the air duct structure of a kiln head blower. Background Art

[0002] A kiln head blower is an industrial device mainly used in a kiln furnace to improve the combustion process by increasing the air flow. It helps to provide a stable air flow to ensure the full combustion of fuel and the temperature control of the kiln furnace, and is widely used in cement, steel and other high-temperature industrial kiln furnaces.

[0003] Since the kiln head blower is mainly used to provide a stable air flow in the kiln furnace to ensure the full combustion of fuel, but due to the relatively high temperature near the furnace, setting the kiln head blower at a place far from the kiln furnace is very helpful for improving the service life of the kiln furnace blower. Therefore, setting an air duct between the kiln head blower and the kiln furnace can make the air flow provided by the kiln head blower directly reach the inside of the kiln furnace and reduce the loss during air flow circulation.

[0004] However, the existing kiln head blower simply uses a square channel to convey the air flow required by the kiln furnace, but a large amount of noise will be generated during the operation of the blower. Therefore, it is necessary to add sound-absorbing and noise-reducing structures inside the air duct to avoid sound pollution. However, most of the existing sound-absorbing and noise-reducing structures are connected to the air duct by welding, which leads to inconvenience in later maintenance of the sound-absorbing and noise-reducing structures.

[0005] Therefore, the utility model proposes an air duct structure for a kiln head blower. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art and propose an air duct structure for a kiln head blower.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: an air duct structure for a kiln head blower, including a blower mechanism and a connecting pipe mechanism. The connecting pipe mechanism is arranged at the output end of the blower mechanism. The connecting pipe mechanism includes an air duct pipe and an air duct connecting pipe. The air duct connecting pipe is arranged at the connection of the air duct pipe. The connecting pipe mechanism is internally embedded with a sound-absorbing component;

[0008] The sound-absorbing component includes a sound-insulating board and a sound-absorbing board. There are two sound-absorbing boards in total, and the two sound-absorbing boards are respectively arranged on both sides of the sound-insulating board. Both ends of the sound-insulating board are slidably connected with magnetic attraction seats, and a magnetic attraction plate is slidably connected to one side of the magnetic attraction seats where the sound-insulating board is located.

[0009] As a preferred implementation manner, the sound-absorbing board is provided with sound-absorbing holes, and the sound-absorbing holes are distributed in a honeycomb shape.

[0010] The beneficial effects of adopting the above further solution are as follows: Through the sound-absorbing holes opened on the sound-absorbing panel, and the sound-absorbing holes are in a honeycomb structure. Under the action of the honeycomb structure, it is used for the dispersion and reflection of sound waves. Since the surface of the honeycomb structure is composed of many small isolation units, these units will reflect and scatter the sound waves after they enter the structure, so that the energy of the sound waves is dispersed, thereby reducing the direct sound transmission and reducing the sound pollution.

[0011] As a preferred implementation manner, mounting strips are arranged on both the upper and lower sides of the magnetic attraction plate on the sound insulation panel.

[0012] The beneficial effects of adopting the above further solution are as follows: The mounting strip is limited by the mounting strip. Since the width of the mounting strip is greater than the width of the magnetic attraction plate, after connecting the mounting strip and the magnetic attraction plate with bolts, the magnetic attraction plate can be effectively prevented from displacing on the sound insulation panel and from detaching from the sound insulation panel.

[0013] As a preferred implementation manner, handles are arranged at both ends of the sound insulation panel.

[0014] The beneficial effects of adopting the above further solution are as follows: Through the setting of the handles, there is a place to grip when taking the sound insulation panel, so as to facilitate removing the sound insulation panel from the air duct.

[0015] As a preferred implementation manner, an activity opening is opened on the air duct, and the width of the activity opening is greater than the width of the handle.

[0016] The beneficial effects of adopting the above further solution are as follows: The activity opening reserves an activity space for the handle, avoiding protrusions at both ends after the sound insulation panel is placed in the air duct, resulting in poor sealing at the connection between the air duct and the air duct connecting pipe, and thus air leakage.

[0017] As a preferred implementation manner, a groove is opened on the outer side of the magnetic attraction seat on the air duct, and the groove is engaged with the magnetic attraction seat.

[0018] The beneficial effects of adopting the above further solution are as follows: The magnetic attraction seat is limited by the groove. Under the action of the magnetic attraction plate, due to the repulsion of the same poles, after the magnetic attraction plate is inserted into the sound insulation panel, it drives the magnetic attraction seat to be engaged in the groove to limit the sound insulation panel, preventing the sound insulation panel from falling off the air duct during the use process.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] 1. In the present utility model, since the sound-absorbing component and the air duct are of a split structure, in actual use, the effect of quick disassembly can be achieved by adjusting the front and back sides of the magnetic attraction plate. During installation, the side of the magnetic attraction plate at the same level as the magnetic attraction seat is inserted into the sound insulation board. Under the principle of like poles repelling each other, the magnetic attraction seat enters the groove and is mutually clamped to achieve the limiting effect. During disassembly, the negative side of the magnetic attraction plate is inserted into the air duct. Under the principle of opposite poles attracting each other, the magnetic attraction seat is driven to retract into the sound insulation board, releasing the limit between the sound insulation board and the air duct, so as to facilitate the removal of the sound-absorbing component from the air duct.

[0021] 2. In the present utility model, since sound-absorbing boards are provided on both the front and back sides of the sound insulation board, in actual use, the noise pollution can be reduced through a double-layer sound-absorbing structure. Moreover, since the sound-absorbing board at the bottom of the sound insulation board is in contact with the air duct, its wear is less than that of the other sound-absorbing board. When maintaining the sound-absorbing component, the sound-absorbing component can be removed and installed on the reverse side, so that the service lives of the double-sided sound-absorbing boards are the same, which can effectively reduce the maintenance cost and improve the service life of the device.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figures 1-5 shown, the present utility model provides a technical solution: a kiln head blower air duct structure, including a blower mechanism 1 and a connecting pipe mechanism 2. The connecting pipe mechanism 2 is arranged at the output end of the blower mechanism 1. The connecting pipe mechanism 2 includes an air duct pipe 21 and an air duct connecting pipe 22. The air duct connecting pipe 22 is arranged at the connection of the air duct pipe 21. An acoustic absorption component 3 is embedded and installed in the connecting pipe mechanism 2; the acoustic absorption component 3 includes a sound insulation board 31 and a sound absorption board 32. There are two sound absorption boards 32 in total, and the two sound absorption boards 32 are respectively arranged on both sides of the sound insulation board 31. Magnetic suction seats 34 are slidably connected to both ends of the sound insulation board 31. A magnetic suction plate 331 is slidably connected to one side of the sound insulation board 31 where the magnetic suction seats 34 are located. Grips 35 are arranged at both ends of the sound insulation board 31. A groove 24 is opened on the outside of the air duct pipe 21 where the magnetic suction seats 34 are located, and the groove 24 is engaged with the magnetic suction seats 34. Since the acoustic absorption component 3 and the air duct pipe 21 are of a split structure, in actual use, the effect of quick disassembly can be achieved by adjusting the front and back sides of the magnetic suction plate 331. During installation, the side of the magnetic suction plate 331 of the same level as the magnetic suction seat 34 is inserted into the sound insulation board 31. Under the principle of like poles repelling each other, the magnetic suction seats 34 enter the groove 24 and are engaged with each other to achieve a limiting effect. During disassembly, the negative side of the magnetic suction plate 331 is inserted into the air duct pipe 21. Under the principle of opposite poles attracting each other, the magnetic suction seats 34 are driven to retract into the sound insulation board 31, releasing the limit between the sound insulation board 31 and the air duct pipe 21, so as to facilitate taking out the acoustic absorption component 3 from the air duct pipe 21, solving the technical problem of the quick installation of the acoustic absorption component 3.

[0033] Even further, as Figure 3 - Figure 4As shown in the figure: Sound-absorbing holes 321 start to appear on the sound-absorbing panel 32. The sound-absorbing holes 321 are distributed in a honeycomb pattern. Through the sound-absorbing holes 321 opened on the sound-absorbing panel 32, and the sound-absorbing holes 321 are of a honeycomb structure. Under the action of the honeycomb structure, it is used for the dispersion and reflection of sound waves. Since the surface of the honeycomb structure is composed of many small isolation units, these units will cause the sound waves to reflect and scatter after entering the structure, dispersing the energy of the sound waves, thereby reducing direct sound transmission and reducing sound pollution. And through the double-layer sound-absorbing structure, the noise pollution is reduced. The sound-absorbing panel 32 at the bottom of the sound insulation panel 31 has less wear because it is in contact with the air duct 21. When the sound-absorbing component 3 needs to be maintained, the sound-absorbing component 3 can be removed and installed on the reverse side, so that the service life of the double-sided sound-absorbing panel 32 is the same, which can effectively reduce the maintenance cost and improve the service life of the device.

[0034] In the above solution, there is also a problem that the magnetic attraction plate 331 is displaced and falls off on the sound insulation panel 31. As Figure 4 shown: In this solution, mounting strips 33 are provided on both the upper and lower sides of the magnetic attraction plate 331 on the sound insulation panel 31. The magnetic attraction plate 331 is limited by the mounting strips 33. Since the width of the mounting strips 33 is greater than the width of the magnetic attraction plate 331, after connecting the mounting strips 33 and the magnetic attraction plate 331 with bolts, it can effectively prevent the magnetic attraction plate 331 from being displaced on the sound insulation panel 31 and prevent the magnetic attraction plate 331 from falling off the sound insulation panel 31.

[0035] In the above solution, there is also a problem that the connection between the air duct 21 and the air duct connecting pipe 22 is not tightly sealed due to the setting of the handle 35. As Figure 3 shown: In this solution, a movable opening 23 is opened on the air duct 21. The width of the movable opening 23 is greater than the width of the handle 35. A movable space is reserved for the handle 35 through the movable opening 23, avoiding protrusions at both ends after the sound insulation panel 31 is placed on the air duct 21, which may cause the connection between the air duct 21 and the air duct connecting pipe 22 to be not tightly sealed, resulting in air leakage.

[0036] Working principle:

[0037] As Figures 1-5As shown in the figure, first, install the blower mechanism 1 at the designated position, install a specified number of air duct pipes 21 according to the distance requirement, and install an air duct connecting pipe 22 at the connection of the air duct pipes 21 according to the actual need, so that the overall air duct can be angled as required. During installation, insert the side of the magnetic attraction plate 331 at the same level as the magnetic attraction seat 34 into the sound insulation plate 31. Under the principle of like poles repelling each other, the magnetic attraction seat 34 enters the groove 24 to be mutually clamped, achieving the limiting effect. During disassembly, insert the negative electrode side of the magnetic attraction plate 331 into the air duct pipe 21. Under the principle of opposite poles attracting each other, drive the magnetic attraction seat 34 to retract into the sound insulation plate 31, releasing the limit between the sound insulation plate 31 and the air duct pipe 21, so as to facilitate taking out the sound absorption component 3 from the air duct pipe 21. When maintaining the sound absorption component 3, the sound absorption component 3 can be removed and installed on the reverse side, so that the service lives of the double-sided sound absorption plates 32 are the same, which can effectively reduce the maintenance cost.

[0038] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
