Technical Field

[0001] The utility model belongs to the technical field of pipeline structures, and in particular relates to a stainless steel air duct structure. Background Art

[0002] Stainless steel air ducts have excellent physical and chemical properties such as corrosion resistance, heat resistance, and high strength. Therefore, stainless steel air ducts are widely used in: dust-free workshop purification systems in the electronics industry, aseptic workshop purification systems for medicine and food, central air-conditioning systems in office buildings and factories, exhaust ducts for dust removal, smoke exhaust, oil absorption, etc. for industrial pollution control, coal mine gas extraction systems, and return air systems for coal mine environment control.

[0003] Stainless steel ducts will inevitably carry impurities during the exhaust process, which will adhere to the inner wall of the stainless steel duct after long-term accumulation, affecting the exhaust effect of the duct. In the use of traditional stainless steel ducts, their interfaces are only fixed by welding, which is troublesome to disassemble. It is very inconvenient for workers to clean the inside of the duct, and the work efficiency is low. Utility Model Content

[0004] The utility model aims to provide a stainless steel air duct structure to solve the problem that the structure of the traditional stainless steel air duct is inconvenient for internal cleaning.

[0006] The working principle and beneficial effect of this solution are as follows: in this solution, the gear is driven to rotate by the rotating rod, and since the first rack and the second rack are respectively meshed with the two ends of the gear, the first rack and the second rack overcome the elastic force of the elastic member and move in opposite directions until the first rack is disengaged from the first locking groove and the second rack is disengaged from the second locking groove, thereby opening the sealing plate and cleaning the inside of the air duct body through the cleaning port. That is, this solution improves the structure of the traditional stainless steel air duct, making the stainless steel air duct detachable and the disassembly operation simple, so that the staff can perform cleaning work and improve work efficiency.

[0007] Optionally, a T-shaped rod is provided on a side wall of the locking block away from the sealing plate, and a brush is provided on the T-shaped rod, and the brush abuts against the inner wall of the air duct body.

[0009] Optionally, there are two T-shaped rods, which are respectively located at two ends of the locking block.

[0010] In this solution, when the number of T-shaped rods is two, compared with when the number of T-shaped rods is one, this solution can brush off more impurities on the inner wall of the air duct body.

[0011] Optionally, a first sealing rubber pad is provided on the locking block, the first sealing rubber pad is tightly pressed against the inner wall of the air duct body, and a through hole for the first rack or the second rack to pass through is opened on the first sealing rubber pad.

[0012] In this solution, the first sealing rubber pad can prevent the gas in the air duct body from entering the cavity of the locking block, thereby preventing the air in the air duct body from leaking through the gap between the rotating rod and the sealing plate, thereby improving the sealing of the stainless steel air duct.

[0013] Optionally, a second sealing rubber pad is provided on a side wall of the sealing plate facing the cleaning port.

[0014] In this solution, the second sealing rubber pad can prevent the gas in the air duct body from leaking out through the gap between the air duct body and the sealing plate, thereby further improving the sealing performance of the stainless steel air duct.

[0015] Optionally, one end of the rotating rod away from the cavity is fixedly connected to a rotating disk.

[0016] In this solution, a turntable is designed on the rotating rod to make it easier for workers to rotate the rotating rod.

[0017] Optionally, a limiting rod is slidably connected to the turntable, and a limiting hole for the end of the limiting rod to extend into is formed on a side wall of the sealing plate facing the turntable.

[0018] In this solution, the end of the limit rod is inserted into the limit hole, so that the limit rod can be fixed to prevent the rotating rod from being accidentally rotated by the staff.

[0019] Optionally, a fixing piece is fixedly connected to a side wall of the sealing plate facing the rotating disk, a connecting rope is bound to the fixing piece, and one end of the connecting rope away from the fixing piece is fixedly connected to the limiting rod.

[0020] In this solution, the limit rod is connected to the sealing plate by a connecting rope to prevent the limit rod from being lost.

[0022] In this solution, one end of the rotating rod is rotatably connected to the side wall of the cavity, and the rotating rod is also rotatably connected to the channel through a bearing, so that the stability of the rotating rod during rotation is improved.

[0023] Optionally, sound insulation cotton is fixedly connected to the inner wall of the air duct body.

[0024] In this solution, the sound insulation cotton plays a certain role in sound insulation and reduces noise pollution. BRIEF DESCRIPTION OF THE DRAWINGS

The left end of the rotating rod 4 is rotatably connected to the left side wall of the cavity 301, and the right end of the rotating rod 4 passes through the sealing plate 2. Specifically, a channel for the rotating shaft to pass through the sealing plate 2 is provided on the sealing plate 2, and the channel extends to the left and communicates with the cavity 301. A bearing 8 is fixedly connected in the channel, and the rotating rod 4 is coaxially fixedly connected with the bearing 8. A rotating disk 9 is welded on the right end of the rotating rod 4 so that the staff can rotate the rotating rod 4 through the rotating disk 9.

[0033] The gear 5 is coaxially fixedly connected to the rotating rod 4, the first rack 6 and the second rack 7 are respectively meshed with the two ends of the gear 5, and the first rack 6 and the second rack 7 are connected to the side wall of the cavity 301 through the elastic member 10. Figure 2 As shown, in this embodiment, the first rack 6 and the second rack 7 are arranged vertically, the first rack 6 meshes with the left end of the gear 5, the second rack 7 meshes with the right end of the gear 5, the bottom end of the first rack 6 is connected to the bottom wall of the cavity 301 through the elastic member 10, and the top end of the second rack 7 is connected to the top wall of the cavity 301 through the elastic member 10. The top inner wall of the air duct body 1 is provided with a first locking groove 11 for the top end of the first rack 6 to be inserted into, and the bottom inner wall of the air duct body 1 is provided with a second locking groove 12 for the bottom end of the second rack 7 to be inserted into. In this embodiment, the elastic member 10 is a telescopic spring, and the elastic member 10 is in a compressed state, the top end of the first rack 6 is inserted into the first locking groove 11, and the bottom end of the second rack 7 is inserted into the second locking groove 12. In this embodiment, a first cavity for vertical movement of the first rack 6 and a second cavity for vertical movement of the second rack 7 are also provided in the locking block 3. In this way, the first cavity and the second cavity are utilized to ensure that the first rack 6 and the second rack 7 can move vertically, thereby being smoothly inserted into the first lock groove 11 and the second lock groove 12.

[0034] The top wall and the bottom wall of the locking block 3 are both bonded with a first sealing rubber pad 13. The first sealing rubber pad 13 on the top wall of the locking block 3 is tightly pressed against the top inner wall of the air duct body 1, and a through hole 131 for the first rack 6 to pass through is provided on the first sealing rubber pad 13 on the top wall of the locking block 3; the first sealing rubber pad 13 on the bottom wall of the locking block 3 is tightly pressed against the bottom inner wall of the air duct body 1, and a through hole 131 for the second rack 7 to pass through is provided on the first sealing rubber pad 13 on the bottom wall of the locking block 3. In this way, the first sealing rubber pad 13 is used to prevent the gas in the air duct body 1 from entering the cavity 301 of the locking block 3 through the gap between the first rack 6 and the locking block 3, and the gap between the second rack 7 and the locking block 3, and then entering the external environment through the channel, thereby preventing the gas in the air duct body 1 from leaking out.

The second sealing rubber pad 14 can prevent the gas in the air duct body 1 from leaking through the gap between the air duct body 1 and the sealing plate 2, thereby further improving the sealing performance of the stainless steel air duct.

[0036] The inner wall of the air duct body 1 is bonded with sound insulation cotton 15, and the sound insulation effect of the sound insulation cotton 15 is utilized to reduce the noise generated during the use of the air duct body 1, thereby reducing noise pollution.

[0037] In this embodiment, when it is necessary to clean the inside of the air duct body 1, the staff rotates the rotating rod 4 counterclockwise through the turntable 9, and the gear 5 on the rotating rod 4 rotates counterclockwise accordingly. Since the first rack 6 and the second rack 7 are both engaged with the gear 5, the first rack 6 overcomes the elastic force of the elastic member 10 and moves downward, and the second rack 7 overcomes the elastic force of the elastic member 10 and moves upward, until the top end of the first rack 6 disengages from the first locking groove 11 and the bottom end of the second rack 7 disengages from the second locking groove 12, completing the unlocking of the locking block 3. The staff can remove the sealing plate 2 to expose the cleaning port of the air duct body 1, which is convenient for the staff to clean the inside of the air duct body 1 and improves the cleaning efficiency.

[0038] After completing the cleaning work, the sealing plate 2 is re-sealed at the cleaning port. Specifically, the staff rotates the rotating rod 4 counterclockwise through the turntable 9 to ensure that the first rack 6 and the second rack 7 do not extend out of the locking block 3, and then snaps the sealing plate 2 at the cleaning port. After the locking block 3 extends into the air duct body 1, the staff releases the turntable 9. When the first rack 6 is aligned with the first locking groove 11, the first rack 6 moves upward under the elastic force of the elastic member 10, and the top end of the first rack 6 is stuck in the first locking groove 11. When the second rack 7 is aligned with the second locking groove 12, the second rack 7 moves downward under the elastic force of the elastic member 10, and the bottom end of the second rack 7 is stuck in the second locking groove 12, so as to lock the locking block 3, thereby realizing the re-sealing of the cleaning port by the sealing plate 2.
