Description

Technical Field

[0001] This utility model relates to the field of ozone generator technology, and in particular to the discharge body structure in a large ozone generator. Background Technology

[0002] An ozone generator, also known as an ozone machine or ozone sterilizer, is a machine specifically designed to produce ozone. Its working principle is based on high-voltage discharge technology, converting oxygen into ozone to produce the required amount of ozone. Therefore, the discharge element is the core component of the entire system, directly affecting the ozone generation efficiency and the overall performance of the equipment. The main function of the discharge element is to decompose oxygen into atomic oxygen under the influence of a high-voltage electric field, which then combines to form ozone.

[0003] The types of discharge elements used in large ozone generators mainly include tubular discharge elements, plate discharge elements, dielectric barrier discharge structures, and honeycomb discharge elements; among them, tubular discharge elements are widely used due to their simple structure and ease of cleaning. A tubular discharge element typically consists of one or more tubular electrodes made of glass, ceramic, or stainless steel, with oxygen or air introduced into the interior as the raw gas, an outer grounded electrode, and a high-voltage electrode in the middle.

[0004] Ozone generators produce a lot of heat during operation, and effective cooling is essential. Otherwise, ozone will decompose while being generated in a high-temperature environment. In existing technologies, cooling water is usually passed between the insulating medium (glass or ceramic) and the tubular electrode made of stainless steel for cooling. However, in actual use, in order to prevent leakage of cooling water, the sealing requirements are high, so the structure is relatively complex, and there is a great safety risk when leakage occurs. Utility Model Content

[0005] The purpose of this invention is to solve the problems of complex cooling structures and high sealing requirements in existing technologies, and to propose a discharge body structure for large ozone generators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The discharge structure in a large ozone generator includes a fixed base with a high-voltage discharge section fixed at one end, and a base with a rotating structure. A fixed ring is fixedly installed inside the base, and the outer wall of the fixed base is threadedly connected to the inner wall of the fixed ring. An insulating tube is fixedly installed at one end of the fixed base, and the high-voltage discharge section is located inside the insulating tube. A cylindrical body extends through both ends, and a grounding electrode is electrically connected to the outer wall of the cylindrical body. One end of the cylindrical body is threadedly connected to the inner wall of the base, and a top cover is threadedly connected to the other end of the cylindrical body. A spiral cooling tube is fixedly installed inside the cylindrical body, and the outer wall of the insulating tube abuts against the spiral inner wall of the cooling tube. Both ends of the cooling tube extend out of the cylindrical body.

[0008] To facilitate water supply and drainage of the cooling pipes, preferably, pipes are fixedly installed on the outer walls of both ends of the cylinder, and the two sets of pipes are respectively connected to the two ends of the cooling pipes for supplying and draining the coolant in the cooling pipes.

[0009] To facilitate the connection between the base and the top cover and to improve the sealing effect at the connection, preferably, a connecting cylinder is fixedly provided at both ends of the cylinder body. The two sets of connecting cylinders are respectively connected to the internal threads of the base and the top cover, and a sealing ring is fixedly provided on the mating surface of the connecting cylinder and the cylinder body. The two sets of sealing rings abut against one end of the base and the top cover, respectively.

[0010] To facilitate the rotation of the cylinder, preferably, an adjustment block with a hexagonal structure is fixedly provided on the outer wall of the cylinder, and the side wall of the adjustment block is provided with a threaded hole for connecting the grounding electrode.

[0011] Preferably, an air inlet pipe is fixedly installed on the base, and an air inlet hole communicating with the air inlet pipe is opened at the other end of the fixed base. An air outlet pipe is fixedly installed on the top cover, and an air outlet hole communicating with the air outlet pipe is fixedly opened at the end of the insulating tube away from the fixed base.

[0012] Preferably, a conductive ball electrically connected to the high-voltage discharge section is fixedly disposed at the other end of the fixed base, and a conductive plate is fixedly disposed on the base, the conductive ball abutting against the conductive plate, and the conductive plate extending out of the base.

[0013] Compared with the prior art, this utility model provides a discharge body structure for a large ozone generator, which has the following beneficial effects:

[0014] 1. The discharge body structure in this large ozone generator is achieved by fixing a spiral cooling pipe on the cylinder. The spiral cooling pipe is sleeved on the insulating pipe, and the inner wall of the cooling pipe abuts against the outer wall of the insulating pipe, thereby cooling the insulating pipe. At the same time, the water inlet and outlet of the cooling pipe are located on the outside of the cylinder, which has low requirements for sealing performance, simple structure, and can reduce the risk of leakage.

[0015] 2. The discharge body structure in this large ozone generator has a connecting cylinder fixedly installed on the cylinder body, which facilitates connection with the base and top cover. In addition, the sealing ring installed on the cylinder body can improve the sealing effect between the cylinder body and the base and top cover, and reduce gas leakage.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model achieves cooling of the insulating tube by fixing a spiral cooling pipe on the cylinder body. The spiral cooling pipe is sleeved on the insulating tube, and its inner wall abuts against the outer wall of the insulating tube.

[0024] Example:

[0025] Reference Figures 1-4 The discharge structure in the large ozone generator includes a fixed base 1 with a high-voltage discharge section fixed at one end, and a base 2 with a rotating structure. A fixing ring 203 is fixedly installed inside the base 2. The outer wall of the fixed base 1 is threadedly connected to the inner wall of the fixing ring 203, which is convenient to install and disassemble and has reliable fixation. An insulating tube 101 is fixedly installed at one end of the fixed base 1. The insulating tube 101 is made of glass or ceramic. Here, we prefer glass. The insulating tube 101 is similar to a test tube structure. Furthermore, the insulating tube 101 is threadedly connected to the inner wall of the fixed base 1. A second sealing gasket is fixedly installed on the fixed base 1. The second sealing gasket is connected to the insulating tube 1. The ends of tubes 101 abut against each other, and a first sealing gasket is fixedly installed on the inner wall of the base 2. The other end of the fixing seat 1 abuts against the first sealing gasket. The first and second sealing gaskets are made of fluororubber, polytetrafluoroethylene, or perfluoroether rubber. Perfluoroether rubber has excellent chemical resistance and high temperature stability, making it particularly suitable for applications requiring extremely high chemical resistance and temperature resistance. The high-voltage discharge section is located inside the insulating tube 101. The high-voltage discharge section is existing technology. Oxygen entering the insulating tube 101 is decomposed into atomic oxygen under the action of the high-voltage electric field, and then combines to form ozone. A conductive ball electrically connected to the high-voltage discharge section is fixedly installed at the other end of the fixing seat 1. 102. A conductive plate 201 is fixedly installed on the base 2. The conductive ball 102 abuts against the conductive plate 201, and the conductive plate 201 extends beyond the base 2. During use, when the fixing seat 1 is tightened inside the base 2, the conductive ball 102 abuts against the conductive plate 201. The conductive plate 201 has a certain elasticity, and a current-carrying wire can be connected to the end of the conductive plate 201 that extends beyond the base 2, thereby facilitating power supply to the high-voltage discharge section. The cylindrical body 4 is a through-hole structure with a rotating body. A grounding electrode is electrically connected to the outer wall of the cylindrical body 4. One end of the cylindrical body 4 is threaded to the inner thread of the base 2, and the other end of the cylindrical body 4 is threaded to... The device has a top cover 3 and a spiral cooling pipe 5 is fixedly installed inside the cylinder 4. The spiral extends along the axis of the insulating pipe 101, with the outer wall of the insulating pipe 101 abutting against the spiral inner wall of the cooling pipe 5. Both ends of the cooling pipe 5 extend outside the cylinder 4. In use, the spiral cooling pipe 5 is fixedly installed on the cylinder 4 and sleeved on the insulating pipe 101, with its inner wall abutting against the outer wall of the insulating pipe 101, thereby cooling the insulating pipe 101. At the same time, the water inlet and outlet of the cooling pipe 5 are located on the outside of the cylinder 4, which has low requirements for sealing, simple structure, and can reduce the risk of leakage.

[0026] Reference Figures 1-3Pipes 501 are fixedly installed on the outer walls of both ends of the cylinder 4. The two sets of pipes 501 are connected to the two ends of the cooling pipe 5 respectively, and are used for the supply and discharge of coolant in the cooling pipe 5. The pipes 501 and the cooling pipe 5 are integrally formed, that is, the pipes 501 are the ends of the cooling pipe 5 that extend out of the cylinder 4. The preferred material is copper pipe. In use, by fixing the pipes 501 on the cylinder 4, on the one hand, since the pipes 501 and the cooling pipe 5 are integrally formed, the cooling water directly enters the cooling pipe 5 through one end of the pipes 501 and then flows out from the other end of the pipes 501, avoiding secondary transfer between the cooling pipe 5 and the cylinder 4, reducing the risk of leakage inside the cylinder 4. On the other hand, it is convenient to introduce cooling water into the cooling pipe 5 and to discharge the cooling water, thus improving the performance.

[0027] Reference Figures 1-4 Connecting cylinders 401 are fixedly installed at both ends of the cylinder 4. The two sets of connecting cylinders 401 are respectively connected to the base 2 and the top cover 3 by internal threads. Sealing rings 403 are fixedly installed on the mating surfaces of the connecting cylinders 401 and the cylinder 4. The two sets of sealing rings 403 are respectively abutted against one end of the base 2 and the top cover 3. In use, by fixing the connecting cylinders 401 on the cylinder 4, it is convenient to connect with the base 2 and the top cover 3. Moreover, the sealing rings 403 on the cylinder 4 can improve the sealing effect between the cylinder 4 and the base 2 and the top cover 3 and reduce gas leakage.

[0028] Reference Figure 1 and Figure 2 An adjustment block 402 with a hexagonal structure is fixedly installed on the outer wall of the cylinder 4. The cylinder 4 and the adjustment block 402 are integrally formed, and the material is preferably stainless steel. The side wall of the adjustment block 402 is provided with a threaded hole for connecting the grounding electrode. In use, by fixing the adjustment block 402 on the cylinder 4, it is convenient to apply force and reduce slippage when rotating the cylinder 4 for threaded connection. Moreover, the threaded hole on the adjustment block 402 allows the grounding electrode to be fixed on the adjustment block 402 by threaded connection, which is convenient for installation and removal.

[0029] Reference Figures 1-3 An air inlet pipe 202 is fixedly installed on the base 2, and the air outlet end of the air inlet pipe 202 is located inside the first sealing gasket. An air inlet hole 103 connected to the air inlet pipe 202 is opened at the other end of the fixed seat 1. An air outlet pipe 301 is fixedly installed on the top cover 3. An air outlet hole 104 connected to the air outlet pipe 301 is fixedly opened at the end of the insulating tube 101 away from the fixed seat 1. In use, by fixing the air inlet pipe 202 on the base 2 and the air outlet pipe 301 on the top cover 3, it is convenient to introduce oxygen into the fixed seat 1 and the insulating tube 101 and to discharge ozone, thereby improving the use effect.
