Description

Technical Field

[0001] This utility model relates to the field of silver plating of glass ornaments, and in particular to a waste gas treatment device for a silver plating tank for glass ornaments. Background Technology

[0002] Silver plating of glass jewelry involves forming a bright silver layer on the glass surface using chemical or electroplating methods, giving the jewelry a metallic texture and aesthetic appeal. Chemical silver plating utilizes a redox reaction to reduce and deposit silver ions on the glass surface; electroplating, on the other hand, relies on an electric current to electrodeposit silver ions from the plating bath onto the glass surface. During the silver plating process, the plating bath releases toxic and harmful gases such as hydrogen cyanide and ammonia. Direct emission of these gases would pose serious threats to the environment and human health.

[0003] Therefore, silver plating tanks for glass ornaments need to be equipped with specialized waste gas treatment devices. Through processes such as absorption and oxidation, harmful substances in the waste gas must be removed to ensure compliance with emission standards. This is crucial for ensuring a safe production environment and achieving green production. However, current waste gas treatment devices have several drawbacks: First, sediment buildup is a significant problem, reducing the absorption efficiency of the absorbent liquid, and the spraying range of the absorbent liquid is relatively small. Second, the devices have poor sealing, and waste gas can easily escape from the joints, affecting the treatment effect and potentially causing environmental pollution and safety hazards.

[0004] Therefore, given the prominent issues of sediment accumulation, the small spray range of the absorbent liquid, and the poor sealing of the device, which leads to the easy escape of exhaust gas from the joints, a waste gas treatment device for silver plating tanks of glass ornaments is needed to solve the above problems. Utility Model Content

[0005] To address the prominent issues of sediment accumulation, limited spray range of the absorbent liquid, and poor device sealing leading to easy leakage of waste gas at joints in existing technologies, this application provides a waste gas treatment device for silver plating tanks for glass ornaments.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A waste gas treatment device for a silver plating tank for glass ornaments includes a cylindrical body. Two metal pipes are rotatably connected to the top side of the cylindrical body. A nozzle is fixedly connected to the bottom end of each metal pipe. A liquid delivery pipe is connected to the top side of each metal pipe via a rotating assembly. An agitator is installed on the top side of the cylindrical body to agitate the sediment at the bottom inside the cylindrical body. An exhaust pipe is fixedly connected to the top side of the outer wall of the cylindrical body. An air inlet pipe is fixedly connected to the bottom side of the outer wall of the cylindrical body. A delivery pipe is connected to the right end of the air inlet pipe via a flange. A sealing assembly is installed inside the air inlet pipe to seal the gap between the air inlet pipe and the delivery pipe. The right end of the delivery pipe is connected to the waste gas discharge port of the silver plating tank.

[0008] As a further improvement of this utility model, the rotating assembly includes two metal rings fixedly connected to the top side of the cylinder, the top side of the metal rings being fixedly connected to one end of the infusion tube, and the other end of the infusion tube being externally connected to a device for conveying the absorbent liquid.

[0009] As a further improvement of this utility model, a first ring is fixedly connected to the bottom side of the metal ring, a second ring is fixedly connected to the top end of the metal tube, a convex ring is fixedly connected to the bottom side of the first ring, and the bottom side of the convex ring is rotatably connected to the inside of the second ring.

[0010] As a further improvement of this utility model, the stirring assembly includes a stirring rod rotatably connected to the inside of the cylinder, a plurality of stirring blades are fixedly connected to the bottom side of the outer wall of the stirring rod, and gears are fixedly connected to the outer wall of both the stirring rod and the metal tube, with adjacent gears meshing with each other.

[0011] As a further improvement of this utility model, a protective shell is fixedly connected to the top side of the cylinder, the gear is located inside the protective shell, the top end of the stirring rod is rotatably connected to the inside of the protective shell, a motor is installed on the top side of the protective shell, and the motor drive end is fixedly connected to the top end of the stirring rod.

[0012] As a further improvement of this utility model, the sealing assembly includes a sealing ring slidably connected inside the air intake pipe, a sealing ring fixedly connected to the right end of the inner wall of the air intake pipe, and a slider fixedly connected to the outer wall of the sealing ring.

[0013] As a further improvement of this utility model, the slider is slidably connected to the outer wall of the air intake pipe, and a positioning block is connected to the top side of the slider by a torsion spring, and the positioning block is engaged with the outer wall of the air intake pipe.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, the intermeshing gears cause the stirring rod to rotate, which in turn drives the metal tube to rotate, thereby agitating the precipitates in the waste liquid, preventing the precipitates from accumulating and affecting the absorption effect of the absorbent liquid, and causing the nozzle to rotate, making the spraying range of the absorbent liquid wider and more uniform, enhancing the contact effect between the waste gas and the absorbent liquid, and improving the waste gas treatment efficiency.

[0016] 2. In this utility model, the sealing ring is slidable so that one side of the sealing ring is inserted into the conveying pipe, thereby sealing the gap between the air inlet pipe and the conveying pipe. This allows the device to achieve a good sealing effect at the joint during installation, preventing exhaust gas from escaping from the joint and improving the sealing effect of the device.

[0031] Example 1:

[0032] like Figures 1-3As shown, a waste gas treatment device for a silver plating tank of glass ornaments includes a cylindrical body 1. Two metal pipes 10 are rotatably connected to the top side of the cylindrical body 1. A drain port is provided on the bottom side of the cylindrical body 1. A nozzle 11 is fixedly connected to the bottom end of the metal pipes 10, through which the absorbent liquid is sprayed into the interior of the cylindrical body 1. A delivery pipe 5 is connected to the top side of the metal pipes 10. An exhaust pipe 3 is fixedly connected to the top side of the outer wall of the cylindrical body 1, through which the treated waste gas is discharged from the cylindrical body 1. Valves are provided inside the drain port and the exhaust pipe 3 to control their opening and closing. The bottom side of the outer wall of the cylindrical body 1 is fixedly connected to... There is an inlet pipe 6, and the right end of the inlet pipe 6 is connected to a conveying pipe 7 via a flange. The exhaust gas is conveyed into the interior of the cylinder 1 through the inlet pipe 6 connected to the conveying pipe 7. An observation window is installed on the bottom side of the cylinder 1 near the inlet pipe 6 to observe the liquid level of the waste liquid, preventing backflow caused by the liquid level exceeding the inlet pipe 6. A one-way valve is installed in the inlet pipe 6 to prevent backflow, and a liquid level detector is installed near the observation window to monitor the liquid level and remind personnel that drainage is required when the liquid level reaches the limit. The right end of the conveying pipe 7 is connected to the exhaust port of the silver plating tank. Figure 1 , Figure 3 and Figure 6 As shown, two metal rings 12 are fixedly connected to the top side of the cylinder 1. The top side of the metal rings 12 is fixedly connected to one end of the infusion tube 5. The other end of the infusion tube 5 is externally connected to a device for conveying the absorbent liquid. This device mainly consists of a storage tank and a delivery pump. A first ring 18 is fixedly connected to the bottom side of the metal rings 12, and a second ring 19 is fixedly connected to the top end of the metal tube 10. A convex ring 20 is fixedly connected to the bottom side of the first ring 18. The bottom side of the convex ring 20 is rotatably connected to the inside of the second ring 19. The convex ring 20 allows the second ring 19 to rotate on the bottom side of the first ring 18, thus allowing the metal tube 10 to rotate normally without affecting the infusion. A sealing gasket can be added between the first ring 18 and the second ring 19 as needed to prevent the absorbent liquid from flowing out. Figures 1-3 As shown, a stirring rod 8 is rotatably connected inside the cylinder 1. Multiple stirring blades 9 are fixedly connected to the bottom side of the outer wall of the stirring rod 8. The stirring rod 8 drives the stirring blades 9 to rotate on the bottom side of the cylinder 1, thereby stirring the sediment on the bottom side of the cylinder 1 and preventing it from accumulating and affecting the absorption effect of the absorbent liquid. Gears 13 are fixedly connected to the outer walls of both the stirring rod 8 and the metal tube 10. Adjacent gears 13 mesh with each other. A protective shell 2 is fixedly connected to the top side of the cylinder 1. The gears 13 are located inside the protective shell 2. The top end of the stirring rod 8 is rotatably connected to the inside of the protective shell 2. The meshing gears 13 cause the stirring rod 8 to rotate, driving the metal tube 10 to rotate. The protective shell 2 protects the gears 13. A motor 4 is installed on the top side of the protective shell 2. The drive end of the motor 4 is fixedly connected to the top end of the stirring rod 8, driving the stirring rod 8 to rotate.

[0033] Example 2:

[0034] As one of the optimized structural designs for Example 1, such as Figure 4 and Figure 5 As shown, a sealing ring 15 is slidably connected inside the intake pipe 6, and a sealing ring 14 is fixedly connected to the right end of the inner wall of the intake pipe 6. By sliding the sealing ring 15, one side of the sealing ring 15 is inserted into the delivery pipe 7, thereby sealing the gap between the intake pipe 6 and the delivery pipe 7. The sealing ring 14 further seals the gap, improving the sealing effect between the intake pipe 6 and the delivery pipe 7 and preventing gas from escaping from the gap. A slider 16 is fixedly connected to the outer wall of the sealing ring 15. The slider 16 is slidably connected to the outer wall of the intake pipe 6. A positioning block 17 is connected to the top side of the slider 16 through a torsion spring. The positioning block 17 is engaged with the outer wall of the intake pipe 6. The sealing ring 15 is slidably connected by the slider 16, and the positioning block 17 is rotated to the outer wall of the intake pipe 6 by the torsion spring, so that the positioning block 17 is engaged with the outer wall of the intake pipe 6.

[0035] Working principle: First, the air inlet pipe 6 and the conveying pipe 7 connected to the exhaust port of the silver plating tank are fixed together by a flange. Then, the slider 16 is moved to insert the sealing ring 15 into the conveying pipe 7, thereby sealing the gap between the air inlet pipe 6 and the conveying pipe 7. Then, the motor 4 is started to drive the stirring rod 8 to rotate. At the same time, the exhaust gas enters the interior of the cylinder 1 through the air inlet pipe 6, and the absorbent liquid is transported to the metal pipe 10 through the liquid delivery pipe 5. Then, the absorbent liquid is sprayed into the cylinder 1 through the nozzle 11 to absorb the exhaust gas. This waste liquid will flow to the bottom of the cylinder 1, and sediment will be generated due to the absorption of exhaust gas. At this time, the stirring rod 8 will drive the stirring blade 9 to rotate on the bottom of the cylinder 1. The sediment at the bottom of the cylinder 1 is stirred to prevent it from accumulating and affecting the absorption effect of the absorbent liquid. When the stirring rod 8 rotates, the meshing gear 13 causes the metal tube 10 to rotate, which in turn causes the nozzle 11 to rotate inside the cylinder 1. This sprays the absorbent liquid to various positions inside the cylinder 1, making the spraying range of the absorbent liquid wider and more uniform, enhancing the contact effect between the waste gas and the absorbent liquid, improving the waste gas treatment efficiency, and ensuring that the waste gas meets the emission standards. The treated waste gas is discharged through the exhaust pipe 3. When the waste liquid level at the bottom of the cylinder 1 reaches the limit level, the device stops working and the valve in the drain port is opened to allow the waste liquid to be discharged from the cylinder 1 through the drain port.
