Description

Technical Field

[0001] This utility model relates to the field of gear ring processing technology, specifically a gear ring acid washing device based on acidic waste gas emission reduction. Background Technology

[0002] A gear ring is a mechanical component with a ring-shaped tooth structure, commonly found in precision transmission and coupling systems. Its function is highly similar to that of a gear ring. During gear ring processing, workers can use an acid pickling device to perform acid pickling treatment on the gear ring. The gear ring acid pickling device is a surface treatment equipment used for precision components such as metal gear rings and gear rings. It removes the oxide layer, rust, and processing residues through the acid pickling process to meet the requirements of subsequent processing or corrosion protection.

[0003] However, current tooth ring pickling devices still have some shortcomings. For example, a pickling device for scrap iron recycling with application number 202320165227.6 has not fully considered the acidic waste gas emission reduction structure of the tooth ring pickling device. During the tooth ring processing, if the tooth ring pickling device does not fully consider the acidic waste gas emission reduction structure, the untreated acidic waste gas will be directly discharged, causing air pollution and serious harm to the environment, human health, and workshop equipment. It is also inconvenient for workers to use the tooth ring pickling device. Utility Model Content

A treatment pipe is fixedly connected to the middle section of the air inlet pipe. The spray assembly is positioned inside the treatment pipe and includes a water supply pipe, a water inlet pipe, and spray nozzles. A discharge pipe is provided below the spray assembly.

[0006] Furthermore, the drive motor is located on the outside of the treatment tank, and the output shaft of the drive motor is fixedly connected to a rotating rod via a coupling. A rotating rod is provided on one side of the rotating rod, and a rotating gear is fixedly connected to the outer wall of the middle section of the rotating rod and the rotating rod.

[0007] Furthermore, the side of the storage frame is provided with a slot, and the rotating gear is meshed with the storage frame through the slot for rotational connection. The ends of the rotating rod and the rotating rod are fixedly connected to a transmission sprocket, and a transmission chain is rotatably connected to the outer side of the transmission sprocket.

[0008] Furthermore, an electric push rod is fixedly connected to the outer wall of the treatment pool, and a limiting roller is fixedly connected to the top of the electric push rod. The middle section of the outer wall of the limiting roller is in contact with the transmission chain, and a limiting rod is rotatably connected to the center of the limiting roller. At the same time, one end of the limiting rod is engaged and slidably connected to the outer wall of the treatment pool.

[0009] Furthermore, fixed blocks are provided on both sides of the rotating gear, and the fixed blocks are welded to the inner sidewall of the treatment pool. The rotating rod and the rotating rod are both connected through the fixed blocks. Moreover, a locking block is welded to the side of the fixed block, and the fixed block is slidably connected to the sidewall of the storage frame through the locking block.

[0010] Furthermore, a snap-fit ​​frame is fixedly connected to the top of the treatment pool, and the treatment pool is snap-fitted to the bottom of the sealing cover through the snap-fit ​​frame. A connecting block is fixedly connected to the outer wall of the treatment pool and the sealing cover, and the connecting blocks are fixedly connected by bolts.

[0011] Furthermore, a feed hopper is fixedly connected to the top side of the sealing cover, and a rotating cover is rotatably connected to the top of the feed hopper via a damping shaft.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figure 1 and Figure 2 As shown, a toothed ring pickling device based on acidic waste gas emission reduction includes a treatment tank 1, a sealing cover 6, and a spray assembly 16. A storage frame 2 is provided inside the treatment tank 1, and a lifting assembly 3 is provided on the side of the storage frame 2. The lifting assembly 3 includes a drive motor 301, a rotating rod 302, a rotating rod 303, a rotating gear 304, a transmission sprocket 305, a transmission chain 306, an electric push rod 307, a limiting roller 308, and a limiting rod 309. The drive motor 301 is located outside the treatment tank 1, and the output shaft of the drive motor 301 is fixedly connected to the rotating rod 302 via a coupling. A rotating rod 303 is provided on one side of the rotating rod 302, and a rotating gear 304 is fixedly connected to the outer wall of the middle section of the rotating rod 302 and the rotating rod 303. A slot is provided on the side of the storage frame 2, and the rotating gear 304 meshes with the storage frame 2 through the slot. The rotating rod 302 and the rotating rod 303 are rotatably connected, and the ends of the rotating rod 302 and the rotating rod 303 are fixedly connected to the transmission sprocket 305. The outer side of the transmission sprocket 305 is rotatably connected to the transmission chain 306. The outer wall of the treatment pool 1 is fixedly connected to the electric push rod 307. The top end of the electric push rod 307 is fixedly connected to the limiting roller 308. The middle section of the outer wall of the limiting roller 308 is in contact with the transmission chain 306. The center of the limiting roller 308 is rotatably connected to the limiting rod 309. At the same time, one end of the limiting rod 309 is engaged and slidably connected to the outer wall of the treatment pool 1. The rotating gear 304 is provided with fixing blocks 4 on both sides. The fixing blocks 4 are welded to the inner side wall of the treatment pool 1. The rotating rod 302 and the rotating rod 303 are both connected through the fixing blocks 4. The side of the fixing blocks 4 is welded with the engaging block 5. At the same time, the fixing blocks 4 are engaged and slidably connected to the side wall of the storage frame 2 through the engaging block 5.

[0024] The specific operation is as follows: The worker places the gear ring workpiece to be processed inside the storage frame 2. Then, the lifting assembly 3 is used to lift the storage frame 2. The drive motor 301 drives the rotating rod 302 to rotate. Under the transmission action of the transmission sprocket 305 and the transmission chain 306, the rotating rod 303 on the other side rotates synchronously with the rotating rod 302. This causes the rotating gear 304, which is fixedly connected to the outer wall of the middle section of the rotating rod 302 and the rotating rod 303, to rotate as well. As the rotating gear 304 rotates, its side is secured by a slot... The device engages and rotates with the storage frame 2, allowing the storage frame 2 to gradually rise and fall. The locking block 5 welded to the side of the fixing block 4 on the inner wall of the treatment tank 1 engages and slides with the side wall of the storage frame 2, ensuring the stability of the storage frame 2 during the rising and falling process. In addition, the operator can use the electric push rod 307 to drive the limiting roller 308 to move. The outer wall of the middle section of the limiting roller 308 contacts the transmission chain 306. Therefore, as the limiting roller 308 moves, the transmission sprocket 305 can be kept taut, preventing derailment and tooth skipping during subsequent operation, making it convenient for the operator to use the toothed ring pickling device.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the sealing cover 6 is positioned above the treatment tank 1. A locking frame 7 is fixedly connected to the top of the treatment tank 1, and the treatment tank 1 is locked to the bottom of the sealing cover 6 via the locking frame 7. A connecting block 8 is fixedly connected to the outer wall of the treatment tank 1 and the sealing cover 6, and the connecting blocks 8 are fixedly connected to each other by bolts. A feed hopper 9 is fixedly connected to one side of the top of the sealing cover 6, and a rotating cover 10 is rotatably connected to the top of the feed hopper 9 via a damping shaft. An arc-shaped block 11 is fixedly connected to the outer wall of the feed hopper 9 and the rotating cover 10, and the arc-shaped blocks 11 are fixedly connected to each other by bolts. An air inlet pipe 12 is provided on one side of the top of the sealing cover 6, and a locking member 13 is fixedly connected to one side of the top of the sealing cover 6. The cover 6 is engaged with the air inlet pipe 12 via the snap-fit ​​part 13, and the outer wall of the cover 6 and the air inlet pipe 12 are fixedly connected to the flange plate 14. Bolts are provided at the four corners of the flange plate 14, and the middle section of the air inlet pipe 12 is fixedly connected to the treatment pipe 15. The spray assembly 16 is located inside the treatment pipe 15, and the spray assembly 16 includes a water supply pipe 1601, a water inlet pipe 1602, and a spray nozzle 1603. The end of the water supply pipe 1601 is fixedly connected to the water inlet pipe 1602, and the water inlet pipe 1602 is fixedly connected through the top of the treatment pipe 15. The bottom end of the water inlet pipe 1602 is fixedly connected to the spray nozzle 1603, and the bottom of the spray assembly 16 is provided with a discharge pipe 17.

[0026] The specific operation is as follows: After the gear ring workpiece to be processed is placed inside the storage frame 2, the operator engages the bottom of the sealing cover 6 with the locking frame 7 fixedly connected to the top of the processing tank 1, and uses bolts to fix the connecting block 8 fixedly connected to the outer wall of the processing tank 1 and the sealing cover 6. Then, the operator opens the rotating cover 10 above the feed hopper 9 on one side of the top of the sealing cover 6 and pours the material from the feed hopper 9 into the processing tank 1. Next, the operator closes the rotating cover 10 and uses bolts to fix the arc-shaped block 11 fixedly connected to the outer wall of the feed hopper 9 and the rotating cover 10. Then, the lifting assembly 3 drives the storage frame 2 to descend. The toothed ring workpiece is gradually immersed in the material for pickling. As the toothed ring workpiece is pickled, acidic waste gas is gradually generated. The acidic waste gas enters the air inlet pipe 12 from the top of the sealing cover 6. At the same time, the operator uses the spray assembly 16 to spray alkaline solution into the treatment pipe 15 in the middle section of the air inlet pipe 12. Under the action of the external pumping structure, the alkaline solution enters the water inlet pipe 1602 from the water supply pipe 1601 and is sprayed out in a mist from the spray nozzle 1603 fixedly connected to the bottom of the water inlet pipe 1602. The alkaline solution and the acidic waste gas undergo a neutralization reaction, thereby reducing the emission of acidic waste gas and facilitating the operation of the toothed ring pickling device.

[0027] In summary, this toothed ring acid washing device based on acidic waste gas emission reduction, according to Figures 1-4The structure shown illustrates that during the pickling process of the gear ring, the pickling device is used to pickle the gear ring. First, after the gear ring workpiece to be processed is placed inside the storage frame 2, the operator engages the bottom of the sealing cover 6 with the locking frame 7 fixedly connected to the top of the treatment tank 1, and uses bolts to fix the connecting block 8 fixedly connected to the outer wall of the treatment tank 1 and the sealing cover 6. Then, the operator opens the rotating cover 10 above the feed hopper 9 on one side of the top of the sealing cover 6, pours the material from the feed hopper 9 into the treatment tank 1, and then closes the rotating cover 10 and uses... Bolts are used to fix the arc-shaped block 11, which is fixedly connected to the outer wall of the feed hopper 9 and the rotating cover 10. Then, the lifting assembly 3 drives the storage frame 2 to descend, and the drive motor 301 drives the rotating rod 302 to rotate. Under the transmission action of the transmission sprocket 305 and the transmission chain 306, the rotating rod 303 on the other side rotates synchronously with the rotating rod 302. This causes the rotating gear 304, which is fixedly connected to the outer wall of the middle section of the rotating rod 302 and the rotating rod 303, to rotate as well. As the rotating gear 304 rotates, its side, through the slot, engages with the storage frame. The frame 2 is engaged and rotated, causing the frame 2 to gradually descend. The locking block 5 welded to the side of the fixing block 4 on the inner wall of the treatment pool 1 engages and slides with the side wall of the frame 2, ensuring the stability of the frame 2 during lifting. Furthermore, the operator can use the electric push rod 307 to move the limiting roller 308. The outer wall of the middle section of the limiting roller 308 contacts the transmission chain 306. Therefore, as the limiting roller 308 moves, the transmission sprocket 305 remains taut, preventing derailment and tooth skipping during subsequent operation. This allows the toothed ring workpiece to gradually immerse itself in the material for pickling. As the gear ring workpiece is pickled, acidic waste gas is gradually generated. The acidic waste gas enters the air inlet pipe 12 from the top of the sealing cover 6. At the same time, the staff uses the spray assembly 16 to spray alkaline solution into the treatment pipe 15 in the middle section of the air inlet pipe 12. Under the action of the external pumping structure, the alkaline solution enters the water inlet pipe 1602 from the water supply pipe 1601 and is sprayed out in a mist from the spray nozzle 1603 fixedly connected to the bottom of the water inlet pipe 1602. The alkaline solution and the acidic waste gas undergo a neutralization reaction, thereby reducing the emission of acidic waste gas and making it convenient for the staff to use the gear ring pickling device.
