Description

Technical Field

[0001] This utility model relates to the field of stripping tank technology, specifically to a stripping tank top suction device. Background Technology

[0002] A stripping tank is a device used to remove plating from metal surfaces. It removes the metal plating from the surface of workpieces through chemical dissolution or electrolysis. It is suitable for reworking defective plating or removing temporary protective plating. However, during the stripping process, the stripping solution in the tank reacts chemically with the plating metal, generating waste gas. Direct emission of this waste gas not only pollutes the working environment but may also harm the respiratory system and skin of operators. Therefore, a top-suction device in the stripping tank uses negative pressure to collect the waste gas generated during the stripping process. Subsequent acid / alkali treatment or other purification methods ensure that the waste gas meets emission standards before being released into the atmosphere.

[0003] The existing technology has the following problems:

[0004] The current top suction device for stripping tanks has a very simple structure and function. It directly sucks away and collects the exhaust gas through the setting of the fan, which cannot perform preliminary treatment of the exhaust gas. At the same time, when the current fan directly sucks away the exhaust gas, the exhaust gas contains a large number of particulate matter. This particulate matter intrudes into the cover and the fan, making it difficult to clean the surface afterward. Furthermore, the intrusion of a large number of particulate matter into the motor of the fan will affect its service life.

[0005] Therefore, we need a top suction device for the stripping tank to solve the above problems. Utility Model Content

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 5 As shown, this utility model provides a top suction device for a plating stripping tank, including a plating stripping tank 1 and a top suction device 2. A groove 11 is provided on the right side of the upper surface of the stripping tank 1, and a baffle plate 12 is fixedly connected to the upper left side of its inner wall. The function of the baffle plate 12 is to block the frame plate 22, ensuring that the frame plate 22 is in a horizontal state when closed. The thickness of the right side of the stripping tank 1 is greater than that of the left side. This thickness setting facilitates the sealing rubber 23 and the rubber block to fit tightly against the groove when the frame plate 22 is closed, thus providing a sealing function. In addition, the upper surface of the baffle plate 12 is at the same level as the upper surface of the inner wall of the groove 11, which facilitates the use of the frame plate 22. An exhaust pipe 24 is fixedly connected to the upper right side of the cover 21. A hose is installed on the outer surface of the exhaust pipe 24. One end of the hose is fixedly installed to the exhaust gas treatment equipment. The exhaust pipe 24 facilitates the transportation of the treated exhaust gas to the exhaust gas treatment equipment through the hose, which facilitates further treatment of the exhaust gas. The exhaust gas treatment equipment is a common component of existing technology, and its specific working principle will not be described in detail here.

[0027] Example 2: Figures 1 to 5 As shown, the top suction device 2 includes a cover 21, a frame plate 22 fixedly connected to the lower outer surface of the cover 21, and a sealing rubber 23 bonded to the outer surface of the frame plate 22. A rubber block 25 is bonded to the right side of the frame plate 22, and the outer surface of the rubber block 25 is in close contact with the inner wall of the groove 11. A rotating shaft is fixedly connected to both the front and rear of the rubber block 25, and the outer surface of the rotating shaft is movably connected through the inner wall of the groove 11. This structure allows the frame plate 22 to rotate to facilitate opening or closing. The rotation of the rotating shaft within the groove 11 ensures that the cover 21 maintains its seal when closed. When the cover 21 is closed, the sealing rubber 23 is in close contact with the inner wall of the stripping tank 1, facilitating the compression and contraction of the sealing rubber 23, thereby achieving a sealing effect.

[0028] A connecting component 28 is provided in the middle of the lower surface of the cover 21, a filter component 26 is provided on the upper surface of the connecting component 28, and an activated carbon plate 27 is provided on the upper surface of the filter component 26. The filter component 26 and the activated carbon plate 27 are placed inside the cover 21 and are detachable. The connecting component 28 has the function of blocking and limiting the filter component 26 and the activated carbon plate 27.

[0029] A motor 29 is fixedly connected to the upper left side of the casing 21. The output shaft of the motor 29 passes through the interior of the casing 21 and is movably connected. A fixing rod 211 is fixedly connected to the output shaft of the motor 29, and a fan blade 213 is fixedly connected to the right end of the fixing rod 211. This structure places the motor 29 outside the casing 21 to prevent exhaust gas from entering the motor 29. When the motor 29 starts, it drives the fixing rod 211 and the fan blade 213 to rotate, thereby sucking away the exhaust gas in the casing 21 and transporting it through the exhaust pipe 24 and the hose. The exhaust gas is treated in the exhaust gas treatment equipment. The upper left side of the cover 21, near the motor 29, is provided with a ventilation port 210. The upper right side of the inner wall of the cover 21 is provided with a smoke outlet 212. The fan blade 213 is located inside the smoke outlet 212. In addition, a support block is fixed on the upper right side of the inner wall of the cover 21, and the outer surface of the fixing rod 211 passes through the inside of the support block and is movably connected. The setting of the support block ensures that the fixing rod 211 always remains in a horizontal straight line, which facilitates the use of the fan blade 213.

[0030] The filter assembly 26 consists of a frame plate 261, a filter cloth 263, and two filter screens 262. The mesh size of the lower filter screen 262 is larger than that of the upper filter screen 262. The filter cloth 263 and the two filter screens 262 are respectively installed and fixed on the inner wall of the frame plate 261. In addition, the arrangement of the two filter screens 262 and the filter cloth 263 has the feature of layered filtration, thereby accommodating particles of different sizes. An inlet 272 is opened on the left side of the lower surface of the activated carbon plate 27, and an outlet 273 is opened on the right side of the upper surface of the activated carbon plate 27. The interior of the 7 has a channel 271, which is shaped like a wave. The wave-shaped channel 271 creates multiple baffles within the channel, extending the contact time with the activated carbon plate 27. The left and right sides of the channel 271 are connected to the interior of the channel 271 and the outlet 273, respectively. This structure allows the filtered exhaust gas to enter the interior through the inlet 272 and make full contact with the interior of the channel 271 for further treatment. The treated exhaust gas is then discharged through the outlet 273.

[0031] Example 3: Figures 1 to 5As shown, the connecting assembly 28 includes a limiting plate 281 and a positioning block 283. The upper right side of the limiting plate 281 is movably connected to the middle right side of the lower surface of the cover 21. This structure allows the limiting plate 281 to rotate, facilitating the removal and replacement of the filter assembly 26 and the activated carbon plate 27. The upper surface of the positioning block 283 is fixedly connected to the middle left side of the lower surface of the cover 21. Sliding grooves 282 are provided on the left side of both the front and rear sides of the limiting plate 281. Sliding sliders 285 are slidably connected inside the front and rear sliding grooves 282. U-shaped sliding blocks are fixedly connected to the outer surfaces of the front and rear sliding sliders 285. Block 284, U-shaped block 284 has a fixedly connected insert block 286 on the middle left side. The outer surface of insert block 286 is inserted into the interior of positioning block 283. This structure facilitates the sliding of U-shaped block 284 and drives insert block 286 into the interior of positioning block 283. The two are magnetically connected to limit the position of limiting plate 281 and prevent rotation. Conversely, by moving U-shaped block 284, insert block 286 is moved out of the interior of positioning block 283 and limiting plate 281 is rotated, which facilitates the disassembly and replacement of filter assembly 26 and activated carbon plate 27.

[0032] Working principle: After the stripping solution inside the stripping tank 1 comes into contact with the workpiece, a chemical reaction occurs, generating waste gas. At the same time, the motor 29 drives the fixed rod 211 to rotate the fan blade 213 inside the smoke outlet 212, thereby generating airflow to easily draw away the waste gas entering the cover 21. The generated waste gas is first filtered through two filter screens 262 and filter cloth 263, and then enters the interior of the channel 271 through the inlet 272, and is then discharged from the interior of the outlet 273. Due to the action of the rotating fan blade 213, the filtered and purified waste gas is discharged. When it is necessary to replace the filter assembly 26 and the activated carbon plate 27, the frame plate 22 is opened, and the U-shaped block 284 can be moved to move the insert block 286 out from the interior of the positioning block 283. Then, after rotating the limiting plate 281 to the appropriate position, it is convenient to remove and replace the filter assembly 26 and the activated carbon plate 27.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
