Description

Technical Field

[0001] This utility model relates to a high-efficiency exhaust pipe for a corona machine, belonging to the technical field of corona machine technology. Background Technology

[0002] A corona discharge machine is a device suitable for the pretreatment of surfaces of silicone rubber, plastics, and other materials. Its working principle involves applying a high voltage to ionize air molecules, then utilizing the movement of these ions to create an ionized wind, thus providing an charged airflow and a certain amount of wind power. A corona discharge machine typically consists of a thin, sharp electrode and a grounded electrode, with a very small distance between them forming a corona discharge region. When a high voltage is applied to the electrode, air molecules near the electrode tip ionize due to the increased electric field strength. After ionization, positive and negative ions are respectively acted upon by the electric field force, creating an environment where the electric field lines flow obliquely towards the airflow.

[0003] The corona machine's exhaust duct is a crucial component. During operation, the machine generates unpleasant and harmful gases that must be expelled through the exhaust duct. The duct also needs to absorb and treat the harmful substances in the gas. However, prolonged use can lead to gas saturation, affecting subsequent treatment. The installation location of the exhaust duct is influenced by the corona treatment location, and the angle of the duct inlet may reduce gas entry efficiency, impacting the duct's efficient exhaust function. Furthermore, during exhaust, free charges in the air adhere to the exhaust duct as the airflow is expelled, generating static electricity and affecting air quality. Utility Model Content

This design achieves efficient exhaust for the corona machine while simultaneously treating the exhaust gas generated during operation, improving the duct's overall performance.

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-3 As shown, the high-efficiency exhaust pipe of the corona machine includes:

[0028] Pipe body 1, one end of which is provided with air outlet 2, an elimination mechanism is fixedly installed inside the pipe body 1 located on one side of the air outlet 2, and a guide mechanism is provided inside the air outlet 2;

[0029] The outer cover 9 is fitted and sleeved to the surface of the tube body 1. The other side of the outer cover 9 is fixedly connected to the end tube 11. A filter mechanism is fixedly installed inside the end tube 11. The inner wall of the end tube 11 is connected to the flow guiding mechanism. The flow guiding mechanism is located inside the tube body 1. The inner wall of the tube body 1 is fixedly connected to the limiting plate 17, and the limiting plate 17 is in contact with the flow guiding mechanism.

[0030] The tube body 1 is a long strip structure with openings on both sides. The tube body 1 is made of insulating material. One opening of the tube body 1 is connected to the air outlet 2, and the other opening of the tube body 1 is distributed correspondingly to the outer cover 9. The surface of the tube body 1 is fixedly connected to the outer cover 9 by bolts 10. The elimination mechanism includes an insulating strip 3 and a metal plate 4. The insulating strip 3 is fixedly connected to the inner wall of the tube body 1. The insulating strip 3 is fixedly connected to both ends of the metal plate 4. The metal plate 4 is an arc-shaped structure with several evenly distributed fine holes.

[0031] In this technical solution, an air vent 2 is set on one side of the pipe body 1 so that the exhaust gas and air during the operation of the corona machine can enter through the air vent 2, and the free charge in the air can pass through the metal plate 4, so that the charge is absorbed by the metal plate 4. The metal plate 4 is connected to the ground through a wire to realize the charge conduction to avoid the generation of static electricity. Furthermore, the connection through the insulating strip 3 can further improve the insulation performance of the exhaust pipe.

[0032] The guiding mechanism includes an air inlet grille 5, and there are several air inlet grilles 5. Several air inlet grilles 5 are rotatably connected to the inside of the air vent 2. Adjacent air inlet grilles 5 are connected to each other through a connecting rod 6. One end of the air inlet grille 5 is fixedly connected to a handle 7 located outside the air vent 2. The edge of the handle 7 is threadedly connected to a knob 8, and the knob 8 is in contact with the outer wall of the air vent 2.

[0033] In this technical solution, the air entering from the air vent 2 is guided by the air intake grille 5, and the air intake grille 5 is rotated by the rotating handle 7. The transmission of the connecting rod 6 realizes the synchronous adjustment of multiple air intake grilles 5. After the adjustment is completed, the knob 8 is tightened to fix it against the outer wall of the air vent 2, which is convenient to adjust according to the installation position of the exhaust pipe and realize the efficient entry of air.

[0034] The end tube 11 has a U-shaped cross-section. A connecting tube 18 is fixedly connected to the middle of the end tube 11, and the connecting tube 18 is distributed correspondingly to the filter mechanism. The filter mechanism includes a side plate 12, which is fixedly connected to the inside of the end tube 11. One side of the side plate 12 is distributed correspondingly to the connecting tube 18, and an activated carbon bag 13 is embedded inside the end tube 11 on the other side of the side plate 12.

[0035] In this technical solution, air is discharged through the connecting pipe 18 and enters the filtration mechanism, where activated carbon pack 13 absorbs and purifies the impurities and odors in the exhaust gas.

[0036] The flow guiding mechanism includes a sieve plate 14, which is fitted to the inner wall of the outer cover 9. A sealing strip 15 is fixedly connected to the edge of the sieve plate 14, extending into the gap between the tube body 1 and the outer cover 9, and the sealing strip 15 is fitted to the edge of the tube body 1. The four edges of the sieve plate 14 are fixedly connected to the flow equalizing plate 16 through branch pipes, and both the two flow equalizing plates 16 and the sieve plate 14 are provided with elongated holes for air flow guiding. There are two flow equalizing plates 16, one of which is narrower than the other, and both flow equalizing plates 16 are fitted to the limiting plate 17.

[0037] In this technical solution, when the outer cover 9 is fixed to the surface of the pipe body 1 by bolts 10, the outer cover 9 abuts against the screen plate 14, so that the sealing strip 15 is fitted into the gap between the outer cover 9 and the pipe body 1, achieving effective sealing at the connection. At the same time, the screen plate 14 drives the two flow equalizing plates 16 to move to the limiting plate 17, and presses them against the surface of the limiting plate 17 to achieve pressing and fixing, ensuring the installation stability of the screen plate 14. The flow equalizing plates 16 play an air guiding role, and at the same time filter larger impurities in the air, so that the airflow can pass smoothly through the activated carbon bag 13 without affecting the air circulation. After long-term use, cleaning can be achieved simply by removing the bolts 10, improving the convenience of use.
