Description

Technical Field

[0001] The invention relates to the technical field of electrostatic spraying, and in particular to an exhaust gas purification device for electrostatic spraying. Background Art

[0002] With the rapid development of industrial technology, electrostatic spraying technology has been widely used in many industries, especially in the fields of automobile manufacturing, home appliance production, metal processing, etc. Electrostatic spraying has become an indispensable part of modern coating technology due to its advantages of high efficiency, uniformity and paint saving. However, the problem of waste gas treatment generated by this efficient coating process has become increasingly prominent, becoming a key factor restricting the optimization of production environment and the achievement of environmental emission standards.

[0003] As an important part of the electrostatic spraying process, the core task of exhaust gas purification is to effectively remove harmful components in the exhaust gas and ensure that the exhaust gas emissions meet the requirements of environmental protection regulations. In this process, coarse filtration, as a preliminary treatment step, bears the important responsibility of filtering large particles of waste, dust and other impurities. Traditional coarse filtration methods mostly use physical blocking technologies such as filter screens. Although these technologies can achieve the separation of impurities in exhaust gas to a certain extent, their limitations cannot be ignored.

[0004] First, after long-term use, the filter is prone to reduce filtration efficiency due to the accumulation of a large amount of dirt. These dirt will not only increase system resistance and reduce the exhaust gas flow rate, but may also cause equipment failure due to blockage, affecting the normal operation of the production line. In addition, as the dirt accumulates on the filter, cleaning becomes extremely cumbersome and time-consuming. Manual cleaning not only increases labor costs, but may also cause secondary pollution due to incomplete cleaning or improper operation.

[0005] Secondly, traditional coarse filtration technology lacks automation and intelligent control methods. In actual production, the cleaning of the filter often requires manual judgment and regular shutdown, which not only increases production uncertainty and maintenance costs, but also may cause frequent interruptions of the production line, affecting production efficiency and product quality.

[0028] By adopting the above technical solution, the double-layer design of the filter 125 stores impurities, and the V-shaped groove 1221 blocks the impurities when the transmission shaft 122 rotates. When the groove is aligned with the docking port 124, the transmission shaft 122 drives the connecting shaft 176 and the limit slider 177 to move, and the bent rod 175 follows, with one side close to the axis and the other side far from the axis. The push plate 1752 at the bottom of the bent rod 175 follows, with a height close to the docking port 124, pushing the cleaning liquid through the port into the V-shaped groove 1221 to wash away the impurities.

[0035] The filter screen 125 is sleeved on the surfaces of the transmission shaft 121 and the transmission shaft 2 122 to form a two-layer filter. The transmission shaft 121 does not rotate in normal state. A cleaning liquid is arranged inside the main body 1. In order to prevent the transmission shaft 2 122 and the filter screen 125 from being soaked in the cleaning liquid for a long time and causing damage, the horizontal plane of the cleaning liquid is located below the transmission shaft 2 122 in normal state. The filter screen 125 needs to be cleaned after being used for a period of time. First, the sealing plate 111 inside the socket 11 is pulled out, and then the telescopic rod 1612 pushes the driving motor 161 to drive the docking gear 1611 to mesh with the gear 2 1622, and then the driving motor 161 drives the gear 2 1622 to rotate through the docking gear 1611, and the gear 2 1622 drives the transmission disc 1 163 and the transmission belt 164 to rotate. The transmission disc 2 165 rotates to control the movement of the screw 167, and the movement of the screw 167 drives the push block 166 to move relatively inside the main body 1. 6 moves, the space of the cleaning liquid inside the main body 1 is reduced, so that the level of the cleaning liquid rises, the push block 166 moves until the cleaning liquid submerges the transmission shaft 2 122, and then the telescopic rod 1612 pulls the driving motor 1 161 to disengage the docking gear 1611 from the gear 2 1622, and then docks it with the gear 1 1621, the docking gear 1611 drives the transmission shaft 1 121 to rotate counterclockwise through the gear 1 1621, and the rotation of the transmission shaft 1 121 drives the filter screen 125 to move around the transmission shaft 1 121 and the transmission shaft 2 122 in a circular manner, at this time, the driving motor 2 172 drives the rotating disk 173 to rotate, and the rotation of the rotating disk 173 drives the swing rod 171 to swing left and right with the positioning bolt 1711 as the center through the driving bolt 1731, and the swing rod 171 swings while driving the transmission shaft 2 122 to move left and right in the limiting slide groove 123, and the movement of the transmission shaft 2 122 drives the filter screen 125 located in the cleaning liquid to shake, so as to achieve the effect of cleaning the filter screen 125; The filter screen 125 is a double-layer filter, so there will be impurities remaining inside it. The V-shaped groove 1221 opened on the surface of the second transmission shaft 122 will jam some impurities in the groove when the second transmission shaft 122 rotates. When this groove moves to dock with the docking port 124, because the two ends of the second transmission shaft 122 will drive the connecting shaft 176 and the limit slider 177 to move, the convex point of the curved rod 175 on one side is close to the second transmission shaft 122, and the limit slider 177 is at the point closest to the second transmission shaft 122, and the concave surface of the second transmission shaft 122 on the other side is close to the second transmission shaft 122, and the limit slider 177 is at the point farthest from the second transmission shaft 122. At the point where the limit slider 177 moves, it will move in one direction at the same time. Because a push plate 1752 is provided at the bottom of the curved rod 175, the movement of the curved rod 175 will drive the push plate 1752 to push the cleaning liquid, and the height of the push plate 1752 is almost the same as the height of the docking port 124, so the push plate 1752 will drive the cleaning liquid into the V-shaped groove 1221 through the docking port 124 to flush the impurities inside. When the push plate 1752 on one side moves toward the transmission shaft 122, a thrust is generated, and when the push plate 1752 on the other side moves away, a pulling force is generated. The cooperation of the two forces can have a good cleaning effect on the V-shaped groove 1221.

[0036] By utilizing the coordination of the motor and the telescopic rod 1612, the meshing of the docking gear 1611 with the gear 1 1621 and the gear 2 1622 is switched, the rotation of the transmission shaft 121 and the movement of the push block 166 are controlled, and the cleaning liquid level is adjusted to ensure that the filter 125 is fully immersed.

[0037] In combination with the cleaning mechanism 17, after the filter screen 125 is soaked, the second driving motor 172 drives the turntable 173, so that the swing rod 171 drives the second transmission shaft 122 to move in the limiting slide groove 123, and shakes the filter screen 125 to clean impurities.

[0038] The V-shaped groove 1221 is designed to capture and gather impurities. When docking, the curved rod 175 and the push plate 1752 are linked to use the bidirectional force of the cleaning fluid for precise flushing.

[0039] The curved design of the curved rod 175 cooperates with the limiting slider 177 and the connecting shaft 176 to generate an opposite force to enhance the cleaning effect. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
