Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to an environment-friendly waste gas purification and treatment device for a mobile phone painting production line. Background Art

[0002] In the mobile phone manufacturing industry, the painting process is a key link in endowing the mobile phone shell with beautiful color, good texture and protective performance. However, this process inevitably generates a large amount of waste gas, posing a severe challenge to the environment and human health. In terms of the waste gas components, the mobile phone painting waste gas contains a variety of volatile organic compounds (VOCs), such as common benzene series substances like benzene, toluene, and xylene, and also includes ethyl acetate, methyl ethyl ketone, isopropyl alcohol, and ethers. Benzene is a colorless, sweet-smelling, and strongly aromatic transparent liquid at room temperature. It is not only flammable but also clearly listed as a carcinogen. Xylene is widely present in synthetic fibers, plastics, fuels, rubbers, as well as various coating additives, adhesives, and waterproof materials. These organic waste gas components are complex, and most of them are toxic and have a pungent smell. If people inhale low-concentration organic waste gas for a long time, it is easy to cause chronic respiratory diseases such as cough, chest tightness, asthma, and even pulmonary emphysema. At the same time, they are also important inducements for the formation of photochemical smog and acid rain. Therefore, an environment-friendly waste gas purification and treatment device for a mobile phone painting production line is designed.

[0003] In the prior art, the activated carbon adsorption structure cannot perform sufficient pre-adsorption on the waste gas, the purification method is single, the purification effect is poor, and the internal maintenance of the equipment is inconvenient. Summary of the Invention

The four lifting seats are connected and driven through the two groups of transmission seats, and a pulley is fixed on the input shaft of the lifting seat. A belt is connected between the output shaft of the third motor and the pulley on the input shaft of the lifting seat.

[0008] In at least some embodiments, Lead screws are installed in all of the four lifting seats. The lower ends of the four lead screws are fixed to a bottom plate. A base is installed at the lower end of the bottom plate through bolts. A sliding seat slides at the lower end of the base. A sliding groove is provided on the sliding seat, and a cylinder seat is installed on the base through bolts. A hydraulic rod is installed on the cylinder seat. A support plate is installed on the sliding seat. The piston rod of the hydraulic rod is fixedly connected to the support plate.

[0009] In at least some embodiments, A rotating rod is installed on the base. A side plate is installed on the rotating rod.

[0015] The present invention provides an environment-friendly waste gas purification treatment device for a mobile phone painting production line, which has the following beneficial effects: In the present invention, the waste gas first passes through the activated carbon column on the internal support plate in the tank. Thanks to its rich porous structure, the activated carbon can preliminarily adsorb various organic pollutants in the waste gas, such as volatile organic compounds like toluene and xylene, effectively reducing the concentration of pollutants in the waste gas and lightening the burden for subsequent treatment. This not only improves the overall purification efficiency but also enables the subsequent neutralization spraying process to react more efficiently with the remaining pollutants. After the waste gas is adsorbed by the activated carbon, it enters the neutralization spraying area. By connecting to an external chemical supply device, the nozzle precisely sprays the appropriate chemical into the waste gas. The fan blades driven by the second motor rotate, which can further disperse the sprayed chemical, making it more evenly distributed in the waste gas, greatly increasing the contact area between the chemical and the waste gas, and promoting their full reaction. For the acidic gas in the waste gas, the alkaline chemical can react with it to produce solid substances such as precipitates, further removing harmful substances in the waste gas, greatly improving the depth of waste gas purification, and ensuring more thorough treatment of the waste gas. After passing through the neutralization spraying, the waste gas finally undergoes fine filtration through the filter pipe. The filter pipe can intercept the residual solid particles, unreacted chemicals, and other impurities in the waste gas, further purifying the gas and ensuring that the finally discharged gas meets or even exceeds the environmental protection standards, providing a reliable guarantee for the waste gas emission of the mobile phone painting production line. The layout of each component is reasonable, enabling the waste gas to smoothly pass through the activated carbon column, the neutralization spraying area, and the filter pipe in sequence, reducing the air flow resistance and improving the treatment efficiency. At the same time, this layout method also facilitates the installation, debugging, and maintenance of the equipment.

[0016] In addition, in the present invention, the gas monitoring sensor continuously monitors the composition and concentration changes of the waste gas at different treatment stages, providing accurate data for the control system from before the activated carbon adsorption to after the neutralization spraying. The barometer monitors the air pressure in the inlet pipe and the outlet pipe in real time, helping to promptly detect abnormal situations such as pipeline blockage and leakage, ensuring the stable transportation of the waste gas throughout the treatment process. The dust sensor monitors the dust content in the tank. In combination with the cleaning pipe connected to an external high-pressure cleaning gas supply device, it can automatically start the cleaning program according to the dust accumulation situation, ensuring the normal operation of components such as the activated carbon column and the filter pipe, maintaining the stability of the entire treatment process, and extending the service life of the equipment.

[0017] In addition, in the present invention, the setting of the liquid storage tank and the sewage discharge pipe can centrally collect and treat the liquid generated after the neutralization spraying reaction, avoiding secondary pollution and achieving a comprehensive environmental protection effect. The inspection port is located between the filter pipe and the fixed seat, facilitating the staff to adjust the angle of the nozzle.

[0018] In addition, in the present invention, operating the No. 3 motor can raise the top cover. The telescopic hydraulic rod precisely controls the flipping angle of the top cover through the telescopic movement of its piston rod. When the top cover is fully opened and flipped to the appropriate position, the activated carbon cylinder in the tank is completely exposed to the staff. The staff can directly stand at the opening of the tank and have all-round access to the activated carbon cylinder. Whether it is the dust and impurities accumulated on the surface of the cylinder or the activated carbon particles saturated with adsorption inside, professional tools can be used for in-depth cleaning.

[0025] In the implementation of the present disclosure, An air inlet pipe 11 and an air outlet pipe 12 are installed on the tank body 1. A barometer 13 is fixed on the tank body 1. The barometer 13 is respectively connected to the air inlet pipe 11 and the air outlet pipe 12. Its function is: the barometer 13 can monitor the air pressure in the air inlet pipe 11 and the air outlet pipe 12 in real time. If the air inlet pipe 11 is blocked, such as blocked by impurities, solid particles, etc., the barometer 13 will detect an abnormal increase in air pressure, and the staff can accordingly check and clean the blockage point in time. If the air outlet pipe 12 leaks, the air pressure will drop significantly, and the barometer 13 can quickly feedback this abnormality, which is convenient for the staff to discover and repair the leakage point in time to prevent the leakage of the purified gas.

[0026] In the implementation of the present disclosure, Two mounting seats 2 are mounted on the tank body 1 by bolts. Fixed rods 21 are fixed on both of the two mounting seats 2. An intermediate seat 22 is fixed between the two groups of fixed rods 21. A third motor 221 is mounted on the intermediate seat 22 by bolts. A pulley is fixed on the output shaft of the third motor 221. Four lifting seats 222 are mounted on the lower end of the intermediate seat 22 by bolts. And two transmission seats 223 are mounted on the lower end of the intermediate seat 22 by bolts. The four lifting seats 222 are connected and driven through the two groups of transmission seats 223. And a pulley is fixed on the input shaft of the lifting seat 222. The pulley on the output shaft of the third motor 221 and the pulley on the input shaft of the lifting seat 222 are connected by a belt. Lead screws 224 are installed in all of the four lifting seats 222. The lower ends of the four lead screws 224 are fixed with a bottom plate 23. A base 24 is mounted on the lower end of the bottom plate 23 by bolts. A sliding seat 241 slides on the lower end of the base 24. A chute is arranged on the sliding seat 241. And a cylinder seat 242 is mounted on the base 24 by bolts. A hydraulic rod 2421 is installed on the cylinder seat 242. A support plate 2411 is mounted on the sliding seat 241. The piston rod of the hydraulic rod 2421 is fixedly connected with the support plate 2411. A rotating rod 244 is mounted on the base 24. A side plate 2441 is mounted on the rotating rod 244. The side plate 2441 is connected to the chute on the sliding seat 241 by bolts. A baffle 243 is mounted on the base 24 by bolts. A buffer rod 2431 is mounted on the baffle 243. Two fixing blocks 2442 are fixed on the rotating rod 244. An installation plate 2443 is fixed at the lower end of the fixing block 2442. A kidney-shaped groove is arranged on the installation plate 2443. A connecting seat 2444 is mounted on the installation plate 2443. A top cover 25 is mounted on the upper end of the tank body 1. The connecting seat 2444 is connected to the top cover 25 by bolts. Its function is: after the third motor 221 is started, its output shaft drives the pulley to rotate, and the power is transmitted to the pulley on the input shaft of the lifting seat by the belt. Since the four lifting seats 222 are connected and driven through the two groups of transmission seats 223, synchronous operation can be ensured. The lead screw 224 in the lifting seat 222 drives the bottom plate 23 and the base 24 to rise smoothly under the drive of the third motor 221, so as to lift the top cover 25 upward. When the top cover 25 needs to be turned over, the hydraulic rod 2421 works, and its piston rod drives the sliding seat 241 to slide on the base 24. Because the side plate 2441 on the rotating rod 244 is connected to the sliding seat 241 by bolts, the rotating rod 244 will rotate accordingly, and then drive the top cover 25 to turn over through the connecting seat 2444. This design realizes the flexible operation of the top cover 25 and creates an open operation space for the maintenance and replacement of components such as the activated carbon cylinder 141 in the tank body 1.

[0027] Example 2, on the basis of Example 1, Inside the tank body 1, a support plate 14 is fixed. At the upper end of the support plate 14, an activated carbon cylinder 141 is installed. And on the inner wall of the tank body 1, a flow-dispersing plate 15 is fixed. On the tank body 1, a cleaning pipe 142 and a dust outlet pipe 143 are installed. Solenoid valves are installed on both the cleaning pipe 142 and the dust outlet pipe 143. The cleaning pipe 142 is connected to an external high-pressure cleaning gas supply device. A dust sensor 17 is installed on the tank body 1. Its functions are as follows: The support plate 14 is fixed inside the tank body 1 to provide stable support for the activated carbon cylinder 141, ensuring that it remains in a fixed position during the waste gas treatment process and will not be displaced due to air flow impact or equipment vibration, guaranteeing that the activated carbon cylinder 141 can continuously and stably play the role of pre-adsorbing waste gas. The flow-dispersing plate 15 fixed on the inner wall of the tank body 1 can evenly disperse the waste gas entering the tank body 1. Before the waste gas enters the activated carbon cylinder 141, the flow-dispersing plate 15 changes the flow direction and speed of the waste gas, making the waste gas contact the surface of the activated carbon cylinder 141 more evenly, improving the adsorption efficiency of the activated carbon for pollutants in the waste gas. The dust sensor 17 is installed on the tank body 1 to monitor the dust content in the tank body 1 in real time. When the dust content reaches a certain threshold, it indicates that the activated carbon cylinder 141 may have accumulated a relatively large amount of dust, affecting the adsorption effect. At this time, the dust sensor 17 feeds back a signal to the control system, and the control system automatically opens the solenoid valves on the cleaning pipe 142 and the dust outlet pipe 143 to start the cleaning program. The cleaning pipe 142 is connected to an external high-pressure cleaning gas supply device. When it is necessary to clean the activated carbon cylinder 141, the solenoid valve on the cleaning pipe 142 is opened, and high-pressure cleaning gas rushes into the activated carbon cylinder 141 at high speed. These high-pressure gases can strongly blow off the dust, impurities, and some adsorption-saturated activated carbon particles accumulated on the surface and inside the pores of the activated carbon cylinder 141. Subsequently, these blown-off substances are discharged from the tank body 1 through the dust outlet pipe 143, realizing the effective cleaning of the activated carbon cylinder 141 and restoring its adsorption activity.

[0028] Embodiment 3, on the basis of Embodiment 1 and Embodiment 2, On the tank body 1, a sewage discharge pipe 38 and a maintenance opening 18 are provided. And a liquid level gauge 16 is installed on the tank body 1. A filter pipe 36 is installed inside the tank body 1. A liquid storage bin 37 is provided at the bottom of the tank body 1. The sewage discharge pipe 38 is connected to the liquid storage bin 37. The maintenance opening 18 is located between the filter pipe 36 and the fixing seat 3. Its functions are as follows: In the neutralization spray reaction stage, unreacted reagents will be generated. The liquid storage bin 37 is located at the bottom of the tank body 1, and its function is to centrally collect these liquids. The liquid level gauge 16 is used to monitor the liquid level height in the liquid storage bin 37 in real time. When the liquid in the liquid storage bin 37 reaches a certain amount or meets the discharge standard after treatment, the liquid can be discharged through the sewage discharge pipe 38. The position of the maintenance opening 18 is convenient for the staff to adjust the angle of the spray head 333. And the staff can easily approach the filter pipe 36 through the maintenance opening 18 to check, clean, or replace the filter screen, ensuring that the filter pipe 36 always maintains good filtering performance.

[0029] Working principle of this embodiment: The waste gas enters the tank body 1 through the intake pipe 11. First, it contacts the activated carbon column 141 on the pallet 14 in the tank body 1. The activated carbon column 141 can preliminarily adsorb various organic pollutants in the waste gas, such as volatile organic compounds like toluene and xylene, effectively reducing the concentration of pollutants in the waste gas. The diffuser plate 15 on the inner wall of the tank body 1 evenly disperses the incoming waste gas, changing the flow direction and speed of the waste gas, enabling the waste gas to contact the surface of the activated carbon column 141 more evenly and improving the adsorption efficiency of the activated carbon. The waste gas after being adsorbed by the activated carbon then enters the neutralization spraying area. The first motor 321 starts, and the pulley on its output shaft drives the rotating seat 31 to rotate through the belt. The upper end of the connecting pipe 34 is connected to the external chemical agent supply device, and the lower end is rotatably connected to the rotating seat 31, which can ensure the stable delivery of the chemical agent to the spray head 333. The spray head 333 accurately sprays the chemical agent adapted to the waste gas during rotation. At the same time, the second motor 351 drives the fan blade 354 at the lower end of the rotating rod 353 on the wall seat 35 to rotate, further dispersing the sprayed chemical agent, making it more evenly distributed in the waste gas, greatly increasing the contact area between the chemical agent and the waste gas, promoting the full reaction between the two, further removing harmful substances in the waste gas, greatly improving the depth of waste gas purification, ensuring more thorough treatment of the waste gas. The waste gas after neutralization spraying is finally finely filtered through the filter pipe 36, and the purified gas is discharged from the tank body 1 through the outlet pipe 12, ensuring that the finally discharged gas meets or even exceeds the environmental protection standards, providing a reliable guarantee for the waste gas emission of the mobile phone painting production line.
