Description

Technical Field

[0001] This utility model relates to the field of ozone generator technology, and in particular to an ozone discharge unit. Background Technology

[0002] An ozone generator is a device used to produce ozone gas. Ozone is easily decomposed and cannot be stored; it must be produced and used on-site (short-term storage is possible under special circumstances). Therefore, ozone generators are necessary wherever ozone is used. Ozone generators are widely used in drinking water, wastewater treatment, industrial oxidation, food processing and preservation, pharmaceutical synthesis, and space sterilization. The ozone gas produced by an ozone generator can be used directly or mixed with liquids through a mixing device to participate in reactions.

[0003] The ozone discharge unit (commonly known as the ozone generating tube or discharge tube) is the core component of an ozone generator. It generates ozone using the principle of dielectric barrier discharge. Under long-term operation, high temperatures, vibration, and ozone corrosion can easily lead to seal failure (air or water leakage) in the ozone discharge unit. Therefore, it is necessary to use tools to unscrew the bolts securing the ozone discharge unit and disassemble it to replace any damaged components. Tubular ozone discharge units are relatively small, and the bolts used are small in diameter (M6, M8, M10), making them prone to falling off or being lost during disassembly. Furthermore, after prolonged use, the bolts are easily loosened by vibration, causing seal failure, affecting performance, and posing safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an ozone discharge unit that can be assembled without bolts, allowing workers to disassemble the ozone discharge unit without tools and avoiding the loss of bolts.

[0005] To achieve the above objectives, an ozone discharge unit is provided, comprising a grounding electrode, an inner dielectric tube sleeved on the outside of the grounding electrode, an outer dielectric tube sleeved on the outside of the inner dielectric tube, a discharge gap for gas flow between the inner and outer dielectric tubes, sealing caps installed at both ends of the inner dielectric tube, and the sealing caps sealing both ends of the discharge gap between the inner and outer dielectric tubes, a high-voltage electrode sleeved on the outer end of the outer dielectric tube, an ozone outlet pipe and an oxygen inlet pipe provided on the outer side of the outer dielectric tube, and the ozone outlet pipe and the oxygen inlet pipe are respectively located at both ends of the high-voltage motor, the inner wall of the sealing cap having an internal thread, and the sealing cap engaging with the outer end of the inner dielectric tube through the internal thread, the sealing cap having an installation groove at one end facing the outer dielectric tube, and the end of the outer dielectric tube extending into the installation groove, the installation groove having an external thread on the side near the internal thread, and the sealing cap engaging with the inner wall of the outer dielectric tube through the external thread. It enables the ozone discharge unit to be assembled without bolts, allowing staff to disassemble the ozone discharge unit without tools and avoiding the loss of bolts.

[0006] According to the ozone discharge unit, a mounting bracket is fixedly connected to the outer end of the sealing cover. A transmission rod is provided in the middle of the mounting bracket, passing through it. The middle part of the transmission rod is rotatably connected to the mounting bracket. A locking block is fixedly connected to the side of the transmission rod facing the outer dielectric tube, located at the end of the transmission rod away from the sealing cover. A spring is fixedly connected to the side of the transmission rod away from the locking block, with the spring and locking block located at the same end of the transmission rod. The end of the spring away from the transmission rod is fixedly connected to the mounting bracket. A slot is provided on the outer side of the outer dielectric tube, and the slot engages with the locking block. The spring pushes the transmission rod and causes the locking block to enter the slot, preventing the outer dielectric tube from rotating on the surface of the sealing cover and preventing the inner dielectric tube from rotating. This avoids loosening of the connection between the outer dielectric tube, the inner dielectric tube, and the sealing cover, which could lead to sealing failure of the ozone discharge unit.

[0007] According to the ozone discharge unit, the side of the mounting groove away from the external thread is fitted against the outer wall of the outer dielectric tube. This prevents dust and impurities from entering the gap between the outer dielectric tube and the sealing cap, which could cause impurities to enter the discharge gap after the ozone power generation unit is disassembled.

[0008] According to the ozone discharge unit, sealing rings are provided between both ends of the outer dielectric tube and the inner dielectric tube and the sealing cap. The sealing rings are used to improve the sealing performance after the connection between the outer dielectric tube, the inner dielectric tube and the sealing cap.

[0009] The above-mentioned solution has the following beneficial effects: 1. The ozone discharge unit is composed of a sealed cover, a high-voltage electrode, an outer dielectric tube, an inner dielectric tube, and a grounding electrode, which facilitates disassembly. 2. The spring pushes the transmission rod, causing the locking block to enter the locking slot, preventing the outer dielectric tube from rotating on the sealing cover surface and the inner dielectric tube from rotating. This prevents the connection between the outer and inner dielectric tubes and the sealing cover from becoming loose, which could lead to the failure of the ozone discharge unit's seal. Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0012] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0013] Reference Figures 1-6This utility model discloses an ozone discharge unit, which includes a grounding electrode 5, an inner dielectric tube 4 sleeved on the outside of the grounding electrode 5, an outer dielectric tube 3 sleeved on the outside of the inner dielectric tube 4, a discharge gap 8 for gas flow between the inner dielectric tube 4 and the outer dielectric tube 3, sealing caps 1 installed at both ends of the inner dielectric tube 4, and sealing caps 1 sealing both ends of the discharge gap 8 between the inner dielectric tube 4 and the outer dielectric tube 3, a high-voltage electrode 2 sleeved on the outer end of the outer dielectric tube 3, and an ozone outlet pipe provided on the outer side of the outer dielectric tube 3. Ozone outlet pipe 6 and oxygen inlet pipe 7 are located at the two ends of the high-voltage motor, respectively. The inner wall of the sealing cover 1 is provided with internal thread 14, and the sealing cover 1 is threaded with the outer end of the inner dielectric tube 4 through the internal thread 14. The end of the sealing cover 1 facing the outer dielectric tube 3 is provided with a mounting groove 16, and the end of the outer dielectric tube 3 extends into the mounting groove 16. The side of the mounting groove 16 near the internal thread 14 is provided with external thread 15, and the sealing cover 1 is threaded with the inner wall of the outer dielectric tube 3 through the external thread 15.

[0014] A mounting bracket 12 is fixedly connected to the outer end of the sealing cover 1. A transmission rod 10 is provided in the middle of the mounting bracket 12, and the transmission rod 10 passes through the mounting bracket 12. The middle part of the transmission rod 10 is rotatably connected to the mounting bracket 12. A locking block 13 is fixedly connected to the side of the transmission rod 10 facing the outer dielectric tube 3, and the locking block 13 is located at the end of the transmission rod 10 away from the sealing cover 1. A spring 11 is fixedly connected to the side of the transmission rod 10 away from the locking block 13, and the spring 11 and the locking block 13 are located at the same end of the transmission rod 10. The end of the spring 11 away from the transmission rod 10 is fixedly connected to the mounting bracket 12. A slot 9 is provided on the outer side of the outer dielectric tube 3, and the slot 9 cooperates with the locking block 13. The spring 11 pushes the transmission rod 10 and causes the locking block 13 to enter the slot 9, preventing the outer dielectric tube 3 from rotating on the surface of the sealing cover 1 and preventing the inner dielectric tube 4 from rotating. This prevents the connection between the outer dielectric tube 3, the inner dielectric tube 4 and the sealing cover 1 from becoming loose, which would lead to the failure of the ozone discharge unit's seal.

[0015] The side of the mounting groove 16 furthest from the external thread 15 is fitted against the outer wall of the external dielectric tube 3. This prevents dust and impurities from entering the gap between the external dielectric tube 3 and the sealing cap 1, which could cause impurities to enter the discharge gap 8 after the ozone generator unit is disassembled.

[0016] Sealing rings are provided at both ends of the outer dielectric tube 3 and the inner dielectric tube 4 and between them and the sealing cap 1. The sealing rings are used to improve the sealing performance after the outer dielectric tube 3, the inner dielectric tube 4 and the sealing cap 1 are connected.

[0017] Working principle: When disassembling the ozone discharge unit, hold the sealing cover 1 and press the end of the transmission rod 10 away from the spring 11 with your finger to make the locking block 13 leave the slot 9. Then, hold the outer dielectric tube 3 of the ozone discharge unit with your other hand and rotate the sealing cover 1 to unscrew the sealing cover 1 at the same end of the outer dielectric tube 3 and the inner dielectric tube 4. Repeat the above operation to unscrew the sealing cover 1 at the other end of the outer dielectric tube 3 and the inner dielectric tube 4, thereby separating the various structures that make up the ozone discharge unit. The spring 11 will cause the operator to release the transmission rod 10 and push the transmission rod 10 to rotate and reset. After the sealing cover 1 is installed on the inner dielectric tube 4 and the outer dielectric tube 3, the locking block 13 will enter the slot 9 on the surface of the outer dielectric tube 3, preventing the outer dielectric tube 3 from rotating on the surface of the sealing cover 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
