Description

Technical Field

[0001] The invention belongs to the technical field of accessory surface polishing equipment, and in particular relates to a surface treatment device for manufacturing accessories of environmental protection equipment. Background Art

[0002] Environmental protection equipment, as a key tool for controlling environmental pollution and improving environmental quality, covers various types of equipment such as air pollution control, water pollution control, solid waste treatment, noise and vibration control, etc. In the production and processing of these equipment, the plates of some accessories need to be surface polished. For example, the inner surface of the sewage treatment reactor can effectively reduce fluid resistance and avoid the attachment of impurities and microorganisms after polishing. For the metal shell of equipment for treating corrosive solid waste, polishing is not only conducive to better adhesion of the anti-corrosion coating, but also can significantly extend the service life of the equipment. Therefore, surface treatment equipment is currently needed for the manufacture of environmental protection equipment accessories. For example, the patent authorization announcement number is CN218697046U, which discloses a surface treatment device for the manufacture of environmental protection equipment accessories.

[0003] At present, when surface treatment equipment is used in the manufacture of environmental protection equipment parts to polish the parts plate, there are the following problems: At present, in the plate polishing process of environmental protection equipment accessories, cooling water is often sprayed to the polishing position to achieve the purpose of reducing the pollution of polishing metal chips and cooling the plate. However, as the polishing continues, the metal chips generated by the polishing of the accessory plate are easily adhered to the surface of the polishing belt under the action of cooling water, and even accumulate in large quantities on the surface of the polishing belt. If the amount of metal chips accumulated is too much, it will seriously affect the polishing effect. At this time, the staff needs to interrupt the operation of the device and manually clean the metal chips on the surface of the polishing belt. However, the manual cleaning process not only affects the convenience and efficiency of the polishing treatment of the accessory plate surface, but also there is a situation where the cleaning is not timely, so that part of the metal chips on the surface of the polishing belt will still act on the surface of the accessory plate with the rotating polishing belt, and it is easy to cause irreversible scratch damage to the surface of the accessory plate, thereby reducing the qualified rate of the polishing treatment of the accessory plate surface, and even causing waste of accessory materials, and also affecting the reliability and effect of the use of the surface treatment device; When the rotating polishing belt continuously polishes the surface of the accessory plate, a large amount of friction heat will be generated at the polishing point. At this time, due to the obstruction of the polishing belt, the sprayed cooling water is difficult to be fully distributed to the polishing point of the accessory plate, resulting in too little cooling water at the continuous polishing point, which cannot meet the high-temperature cooling demand generated by the continuous polishing, and then the temperature of the polishing point continues to rise to form a high-temperature environment. This high-temperature environment is likely to cause the polishing point of the accessory plate to expand due to heat, and then the rotating polishing belt is likely to over-polish the expanded part of the accessory plate, making it easy for the accessory plate to be over-polished and damaged after cooling and shrinking. This not only affects the accuracy of the surface treatment device in polishing the surface of the accessory plate, but also affects the qualified rate of the polishing processing of the surface of the accessory plate, and even causes the problem of waste of accessory materials.

[0004] Therefore, a surface treatment device for manufacturing environmental protection equipment parts is proposed to solve the above problems. Summary of the invention

[0014] Compared with the existing technology, the advantages of a surface treatment device for manufacturing environmental protection equipment accessories are: Through the metal powder collection mechanism, hollow shell and drive motor, when the environmental protection equipment accessory plate needs to be polished, the PLC controller first controls the electric push rod to adjust the position of the polishing belt according to the thickness of the accessory plate and the polishing size. When the position of the polishing belt is adjusted, the PLC controller controls the drive motor to drive the two polishing belts to rotate. Then the staff takes the accessory plate to the polishing belt for polishing. Then during the polishing process, the metal powder collection mechanism collects the metal powder generated by polishing to avoid the metal powder from scattering and interfering with the polishing, and to avoid polluting the surrounding environment.

[0015] Through the provided cleaning mechanism, when the polishing belt performs surface polishing on the accessory plate, the PLC controller also controls the micro water pump in the cleaning mechanism to start, and then the cleaning mechanism transports the micro water pump to suck water to the first water nozzle and the second water nozzle.

The water sprayed by the second water nozzle will be transported to the V-shaped cleaning rod, and then the metal powder adhered to the surface of the polishing belt is rinsed. While rinsing, the cleaning brush at the bottom of the V-shaped cleaning rod can also brush the surface of the polishing belt to ensure that the polishing belt and the surface of the accessory plate will not be scratched due to the interference of residual metal powder, and the water spraying amount of the cleaning mechanism is adjusted by detecting the metal powder content of the water after the polishing belt is cleaned through the energized resistance rod, so as to avoid the waste of water caused by the continuous high-power pumping of the micro water pump, so that the surface treatment device for manufacturing accessories of environmental protection equipment not only has the function of automatic cleaning of the polishing belt, but also has the function of automatic adjustment of the amount of water for cleaning the polishing belt.

[0016] Through the polishing temperature adjustment mechanism, when the polishing belt of the surface treatment device for manufacturing environmental protection equipment accessories continues to polish a certain surface of the accessory plate, the high-precision infrared temperature sensor in the polishing temperature adjustment mechanism detects the surface temperature of the accessory plate between the two polishing belts. If the temperature value detected by the high-precision infrared temperature sensor exceeds the high temperature threshold preset by the PLC controller, the PLC controller controls the semiconductor refrigeration plate and the micro solenoid valve to start, so as to achieve the purpose of cooling the air in the heat insulation cover. Finally, the low-temperature air can reduce the temperature of the polishing part of the accessory plate and the surface of the polishing belt, thereby avoiding high-temperature expansion of the polishing part of the accessory plate, and avoiding excessive polishing of the surface of the accessory plate due to high-temperature expansion. This mechanism enables the surface treatment device for manufacturing environmental protection equipment accessories to have the function of preventing high-temperature interference at the polishing part of the accessory plate, which can effectively improve the accuracy of the surface treatment device in polishing the accessory plate surface, and can also improve the qualified rate of the polishing processing of the accessory plate surface.

[0024] The electric push rod 3, semiconductor cooling plate 74, micro water pump 82, drive motor 15 and micro solenoid valve 18 are all electrically connected to the output end of the PLC controller 16 through wires, and the high-precision infrared temperature sensor 72 and the energized resistor rod 811 are electrically connected to the input end of the PLC controller 16 through wires. The energized equipment and electrical connections are prior arts and are well known to those skilled in the art, and will not be described in detail here.

[0025] The operating principle of the present invention is now described as follows: when the environmental protection equipment accessory plate needs to be polished, first the PLC controller 16 controls the electric push rod 3 to start, the electric push rod 3 pushes the mounting shell 4 downward, the mounting shell 4 drives the polishing belt 10 to adjust the position, so that the position of the polishing belt 10 matches the polishing size required for the accessory plate, the PLC controller 16 controls the moving end of the electric push rod 3 to pause moving, specifically, the distance between the bottom of the polishing belt 10 and the upper surface of the support frame 1 is the thickness of the accessory plate after polishing, the PLC controller 16 controls the driving motor 15 to start, the driving motor 15 drives the rotating roller 5 to rotate, and the rotating roller 5 drives the two polishing belts 10 to rotate, and then the staff holds the accessory plate to the support frame 1, and polishes the accessory plate close to the rotating polishing belt 10; When the polishing belt 10 polishes the accessory plate, the output end of the driving motor 15 rotates the second sprocket 65 through the first sprocket 64 and the transmission chain 66, and the second sprocket 65 rotates the rotating shaft of the vacuum pump body 61. The rotation of the rotating shaft drives the impeller located inside the air guide shell of the vacuum pump body 61 to rotate. The rotating impeller cooperates with the air guide shell to suck air, and the vacuum pump body 61 sucks the air inside the hollow shell 13 through the bent pipe 63, so that the hollow shell 13 is in a negative pressure state. Then the hollow shell 13 in the negative pressure state sucks the air at the polishing point of the polishing belt 10 through the rectangular feed hole 67, the mounting shell 4 and the air inlet channel 23. At this time, the air will carry the metal powder generated by polishing into the hollow shell 13. Since the distance between the bottom of the mounting shell 4 and the upper surface of the accessory plate is short, the air inlet channel 23 is When the air is sucked from the bottom of the assembly shell 4, it can be transported with metal powder, so as to prevent the metal powder generated by the polishing of the accessory plate from scattering and polluting the environment and interfering with the polishing. The air ejected from the output end of the vacuum pump body 61 is transported to the heat insulation cover 62, and finally transported to the annular cavity 68 through the rectangular tube 610, and finally sprayed to the polishing part of the accessory plate through the air nozzle 69. The air ejected by the air nozzle 69 can also cool and clean the polishing part of the accessory plate. At this time, the air sucked by the vacuum pump body 61 will be filtered by the sponge filter element 601 in the air inlet end of the vacuum pump body 61, so as to prevent the metal powder from entering the annular cavity 68 with the air. The sponge filter element 601 at the air inlet end of the vacuum pump body 61 can also prevent the small droplets inside the hollow shell 13 from entering the annular cavity 68. At the same time, the PLC controller 16 also controls the micro water pump 82 to start, and the micro water pump 82 sucks the water in the water tank 81. Then the water enters the first hollow bar 84 through the delivery pipe 83, and the water in the first hollow bar 84 is also delivered to the second hollow bar 87 through the extension pipe 86. Then the water in the first hollow bar 84 is sprayed out through the first water nozzle 85 and sprayed onto the surface of the polishing belt 10 to moisten the surface of the polishing belt 10. The moist polishing belt 10 can not only cool the polishing part during the polishing process, but also settle the metal powder transmitted by the polishing to prevent the metal powder from floating. Finally, the water remaining at the polishing part of the surface of the accessory plate will be converted into small droplets by the air flow under the dual effects of the negative suction of the negative pressure hollow shell 13 and the air sprayed by the air nozzle 69, and then the small droplets The water liquid sprayed by the second water nozzle 88 will be transported to the V-shaped cleaning rod 89, and then fall on the surface of the polishing belt 10 at the V-shaped cleaning rod 89. At this time, the water liquid can wash the metal powder chips adhering to the surface of the polishing belt 10. At the same time, the cleaning brush 810 at the bottom of the V-shaped cleaning rod 89 can also brush the surface of the polishing belt 10 to ensure that the polishing belt 10 and the surface of the accessory plate will not be scratched due to the interference of residual metal powder chips during polishing, thereby ensuring the polishing effect of the accessory plate. In addition, the water liquid sprayed by the second water nozzle 88 will be negatively sucked by the negative pressure hollow shell 13 after cleaning the surface of the polishing belt 10, and will enter the hollow shell 13 through the rectangular feed hole 67 for storage, thereby avoiding water leakage; Moreover, the water after cleaning of the polishing belt 10 that enters the hollow shell 13 through the rectangular feed hole 67 will first contact the powered resistor rod 811. If the water after cleaning the polishing belt 10 contains a large amount of metal chips, the metal chips will cooperate with the water to form a low-resistance conductive layer on the surface of the powered resistor rod 811, so that the circuit resistance of the powered resistor rod 811 input to the PLC controller 16 is greatly reduced, and at the same time, an electrical signal change is generated to the PLC controller 16. The PLC controller 16 controls the pumping power of the micro water pump 82 to increase according to the electrical signal change. The pumping power of the micro water pump 82 is inversely proportional to the resistance value of the powered resistor rod 811, so that more water is delivered to the second water nozzle 88, and then a large amount of water is used to reliably clean the polishing belt 10 with a large amount of metal chips attached, so as to avoid the residual metal chips on the polishing belt 10 interfering with the polishing quality. On the contrary, if the water after cleaning the polishing belt 10 contains less metal chips, it indicates that the polishing amount of the accessory plate is less, the amount of metal chips at the polishing point is lower, and the metal The amount of powder adhering to the surface of the polishing belt 10 is relatively low, and the low-content metal powder combines with water to form a relatively high-resistance conductive layer on the surface of the powered resistor rod 811, so that the circuit resistance of the powered resistor rod 811 input to the PLC controller 16 is reduced less, and at the same time, a corresponding electrical signal change is generated to the PLC controller 16. The PLC controller 16 controls the pumping power of the micro water pump 82 to reduce according to the electrical signal change, and only a small amount of water is needed to complete the surface cleaning of the polishing belt 10, thereby avoiding waste of water in the water tank 81. This mechanism enables the surface treatment device for the manufacture of environmental protection equipment accessories to not only have the functions of cleaning the surface of the accessory plate and automatically cleaning the polishing belt 10, but also has the function of automatically adjusting the amount of water for cleaning the polishing belt 10, thereby avoiding the situation where the polished surface of the accessory plate is disturbed by the metal powder after polishing and causing irreversible scratch damage, thereby improving the qualified rate of the surface polishing of the accessory plate, avoiding waste of materials, and improving the reliability and effect of the use of the surface treatment device.

[0026] When the polishing belt 10 of the surface treatment device continues to polish a certain surface of the accessory plate, the high-precision infrared temperature sensor 72 detects the surface temperature of the accessory plate between the two polishing belts 10, and transmits the detected temperature to the PLC controller 16 in the form of an electrical signal. If the temperature value detected by the high-precision infrared temperature sensor 72 exceeds the high temperature threshold preset by the PLC controller 16, the PLC controller 16 controls the semiconductor refrigeration plate 74 and the micro solenoid valve 18 to start, and the cooling side of the semiconductor refrigeration plate 74 generates a low temperature, and reduces the temperature of the surface of the metal mesh plate 22 and the inside of the heat insulation cover 62. Then, the air transported to the inside of the heat insulation cover 62 by the vacuum pump body 61 is cooled, and the cooled low-temperature air is transported to the annular cavity 68, and finally sprayed onto the surface of the accessory plate and the polishing belt 10 through the air nozzle 69, thereby reducing the polishing area of ​​the accessory plate and the surface of the polishing belt 10. temperature, thereby avoiding high-temperature expansion at the polishing part of the accessory plate, and avoiding over-polishing of the accessory plate surface due to high-temperature expansion. At the same time, the water in the spray tube 17 is sprayed onto the heat sink 21 through the micro-solenoid valve 18, and the cooling effect of the semiconductor refrigeration plate 74 is ensured by accelerating the heat dissipation of the heat sink 21. If the temperature at the polishing part of the accessory plate does not exceed the high-temperature threshold preset by the PLC controller 16, the semiconductor refrigeration plate 74 will not start, thereby reducing the power consumption of the device and improving the energy-saving and environmental protection performance of the device. This mechanism enables the surface treatment device for the manufacture of environmental protection equipment accessories to have the function of preventing high-temperature interference at the polishing part of the accessory plate surface, thereby avoiding damage to the accessory plate due to over-polishing, and can effectively improve the accuracy of the surface treatment device in polishing the accessory plate surface, and can also improve the qualified rate of the accessory plate surface polishing processing.
