Description

Technical Field

[0001] This utility model relates to the technical field of industrial degreasing tank devices, and in particular to a side air extraction device for degreasing tanks. Background Technology

[0002] Degreasing, as a crucial pretreatment step before electroplating, primarily aims to clean oil stains from product surfaces to prepare for the electroplating process. However, as production continues, oil accumulates in the degreasing tank, affecting the degreasing effect. In the field of industrial metal surface treatment, the degreasing tank is a core piece of equipment that removes oil stains from workpiece surfaces through chemical dissolution, emulsification, or thermal decomposition, providing a clean substrate for subsequent electroplating, coating, and welding processes. During degreasing, the high-temperature tank solution or chemical reactions continuously release oil mist, volatile organic compounds, and acid / alkali fumes. If allowed to diffuse into the workshop environment, this can lead to equipment corrosion, secondary contamination of workpieces, harm to operator health, and environmental emission risks. Therefore, the degreasing tank-side exhaust device, as a key environmental protection device for the directional collection, transport, and treatment of these pollutants, creates a negative pressure field at the tank edge to forcibly capture volatiles, making it an indispensable supporting facility in the industrial degreasing process.

[0003] Early oil removal tank extraction devices mostly adopted a crude structure of a single fixed extraction port and a simple fan. The extraction port was usually a fixed circular or rectangular opening, and basic extraction was achieved solely through fan power. Due to the fixed position of the extraction port and limited coverage, such devices could not adapt to fluctuations in the tank liquid level or the oil mist diffusion trajectory when workpieces entered or exited, often resulting in localized extraction blind spots. This led to a large amount of oil mist escaping into the workshop, and the lack of targeted purification components meant that the directly emitted exhaust gas would cause environmental pollution. To solve these problems, existing extraction devices have been gradually optimized into an integrated structure of side-suction or top-suction hoods + multi-stage air ducts + filtration and purification units + a power fan. The coverage area is expanded by using strip-shaped side-suction hoods that match the tank edge, and pre-treatment with filters and baffles is added. The components initially intercept oil mist, and the variable frequency fan regulates the air volume, effectively improving the extraction efficiency and basic purification effect. However, the existing equipment still faces prominent problems of oil accumulation and blockage and maintenance difficulties during long-term operation. After the oil mist enters the duct through the air intake, some oil droplets will condense and adhere to the inner wall of the duct and the surface of the filter components. As the operating time accumulates, the oil stains gradually thicken and block the airflow channels, resulting in a decrease in extraction air pressure and an increase in energy consumption. However, in the existing structure, the duct is mostly an integrated welded design, and the connection between the filter components and the air intake is mostly fastened with bolts. Cleaning requires stopping the machine to disassemble the duct section or filter unit, which is not only cumbersome and time-consuming, but also aggravates component wear due to frequent disassembly, affecting the stability of continuous operation of the equipment.

[0004] To overcome the above shortcomings, this utility model provides an oil removal tank side air extraction device, which aims to improve the problems of oil accumulation and blockage and maintenance difficulties caused by long-term air extraction in the prior art.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the linkage between the first rotating shaft and the second rotating shaft allows the turbine blades to rotate synchronously and adhere closely to the inner wall of the exhaust pipe when the fan is drawing air. This can remove the attached oil stains in real time, avoiding pipe blockage caused by prolonged air drawing. The collection component can collect the scraped oil stains. Combined with the rotatable filter screen, it not only ensures the gas filtration effect but also facilitates the separate cleaning of the filter screen and the collected oil stains. This solves the problems of reduced air drawing efficiency due to oil accumulation and blockage in the prior art and the need to disassemble the pipes for maintenance, thus improving the continuous operation stability and maintenance convenience of the device.

[0014] 2. In this utility model, the slider at the bottom of the support plate slides in conjunction with the slide groove of the slide rail, thereby enabling flexible adjustment of the overall position of the device. It can be adapted to different sizes of degreasing groove edges. The limiting block cooperates with the slide rail to limit the sliding range, and the left and right protective blocks further prevent derailment during adjustment. This solves the problem in the prior art that it is impossible to adaptively adjust to different degreasing groove edge sizes, and improves the versatility and ease of operation of the equipment.

[0020] Reference Figure 4 and Figure 6The collection component 205 includes a collection pipe and an oil collection tank 2051. The collection pipe and oil collection tank 2051 serve as a temporary oil storage channel to collect oil flowing down from the inner wall of the exhaust pipe 204. The top of the collection pipe and oil collection tank 2051 is connected to the bottom of the inner wall of the exhaust pipe 204. This connection structure allows the oil scraped down from the exhaust pipe 204 to flow smoothly into the collection pipe and oil collection tank 2051. Slide grooves 2052 are provided on both the left and right sides of the collection pipe and oil collection tank 2051. The slide grooves 2052 provide a sliding track for the handle 2053 and limit its movement. To control its direction of movement, handles 2053 are slidably connected to the inner wall of the chute 2052. The handles 2053 are used for the operator to hold and drive the push block 2055 to move. The push block 2055 is fixedly connected to the adjacent side of the two handles 2053.

[0021] Reference Figure 1 and Figure 2The bottom of each of the two protective blocks 306 is fixedly connected to a chassis 10. The chassis 10 increases the contact area with the ground to enhance the support stability of the protective blocks 306 and prevent them from tipping over. The top of each of the two protective blocks 306 is fixedly connected to a baffle 11. The baffle 11 is used to block oil mist or liquid that may splash during the suction process to protect the surrounding environment and operators. The bottom of the first stabilizing block 5 is fixedly connected to a suction cup 12. The suction cup 12 is used to adhere to the ground to further enhance the fixing effect of the first stabilizing block 5 and prevent the device from shifting. The top of the outer wall of the exhaust pipe 204 is equipped with a motor 13. The motor 13 is used to provide power to drive the first rotating shaft oil scraper 202 and the second rotating shaft 207 to rotate. The outer wall of the filter screen 206 is also rotatably connected to the inner wall of the dust cover 9. This connection method is used to form a double fixation for the filter screen 206 and facilitate its rotation and cleaning. The bottom of the dust cover 9 is also fixedly connected to the top of the support block 4. This fixing structure is used to enhance the installation stability of the dust cover 9 and prevent it from loosening and falling off. Specifically, the bottom of the two protective blocks 306 is fixedly connected to the chassis 10. The chassis 10, by increasing its contact area with the ground, works with the protective blocks 306 to enhance support stability and prevent the protective blocks 306 from tipping over. The top of the two protective blocks 306 is fixedly connected to the baffle 11. The baffle 11, relying on the support of the protective blocks 306, blocks oil mist or liquid that may splash during the suction process, thus protecting the surrounding environment and operators. The bottom of the stabilizing block 5 is fixedly connected to the suction cup 12. The suction cup 12, through its adsorption with the ground, works with the stabilizing block 5 to improve the fixing effect and prevent the entire device from shifting. Exhaust pipe 2 A motor 13 is installed at the top of the outer wall of 04. The installation relationship between the motor 13 and the exhaust pipe 204 provides power to the rotating shaft 1 oil scraper 202 and the rotating shaft 207, driving them to rotate to achieve the functions of air extraction and oil scraping. The outer wall of the filter screen 206 is rotatably connected to the inner wall of the dust cover 9. This connection, together with the dust cover 9, forms a double fixation for the filter screen 206. At the same time, the rotating structure facilitates the cleaning of the filter screen 206. The bottom of the dust cover 9 is fixedly connected to the top of the support block 4. This fixation, together with the load-bearing capacity of the support block 4, enhances the installation stability of the dust cover 9 and prevents the dust cover 9 from loosening and falling off.

[0022] Working principle: Before operation, the connecting block 1 is fastened to the edge of the oil removal tank by the fixing device 6 and fixing screws 7. The stabilizing block 5 supports the connecting block 1 to form a stable structure with the ground, providing a solid foundation for the air extraction operation. The starting motor 13, model Y132S-6, with a power of 3kW and a synchronous speed of 1000r / min, is then started. After the motor 13, the power is transmitted to the oil scraper 202 on the first rotating shaft via the rotating shaft 207, which drives the fan 203 to rotate at high speed to generate negative pressure. The turbine blade 208, which rotates synchronously with the rotating shaft 207, rotates at high speed against the inner wall of the exhaust pipe 204, removing the condensate adhering to the airflow. The oil stains are scraped off in real time. The scraped oil stains slide down the inner wall of the exhaust pipe 204 to the oil collection tank 2051 of the collection pipe by gravity. The gas is discharged after being filtered by the filter screen 206. When maintenance and cleaning are required, there is no need to disassemble the pipe. Push the handle 2053 to drive the push block 2055 to move horizontally in the oil collection tank 2051 of the collection pipe, pushing the oil stains accumulated in the pipe to the oil storage block 2054. Then the oil storage block 2054 can be directly rotated off along the slide groove 2052 to complete the oil stain cleaning. This avoids pipe blockage caused by long-term air extraction and greatly simplifies the maintenance process, solving the problems of difficult oil accumulation and time-consuming maintenance in traditional devices. Furthermore, when adapting to oil removal tank edges of different widths or positions, the device uses the support plate 301 as the load-bearing base and slides the slider 302 along the inner wall of the slide groove 305 of the slide rail 304 to achieve precise fine-tuning of the overall horizontal position. During the sliding process, the movement range of the slider 302 is limited to prevent the device from derailing due to excessive adjustment. The chassis 10 provides stable support for the protective block 306, enhancing the overall structure's anti-shaking ability during fine-tuning. The baffle 11 blocks splashing oil mist or liquid during adjustment and air extraction operations, ensuring operational safety. Position calibration can be completed without disassembly and reassembly, solving the problem of poor adaptability of traditional fixed structures and improving the equipment's versatility and ease of operation.
