Description

Technical Field

[0001] The utility model relates to an ozone generator with a tubular structure, belonging to the technical field of ozone generating equipment. Background Art

[0002] Commonly used tubular ozone generators are mainly composed of an outer metal tube and an inner non-metal tube. In order to ensure that there is enough discharge gap between the two layers of tubes, they must be accurately positioned. At present, the main positioning method is soft connection. However, in actual operation, soft connection still has many problems. At present, many manufacturers only use a simple soft gasket placed between the two layers of pipes. This method cannot ensure that the discharge gap between the tubes is uniform, resulting in poor discharge effect and greatly reduced ozone production. Therefore, a tubular structure ozone generator is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a tubular ozone generator to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tubular ozone generator, comprising a metal outer tube, both ends of the metal outer tube are sleeved with a tube cap for fixing and installing, a non-metallic tube is concentrically sleeved inside the metal outer tube, and a radial gap exists between the metal outer tube and the non-metallic tube;

[0005] A plug is fixed on the inner wall of each pipe cap, and the plug is fixed on the pipe cap by a screw. The outer wall of the plug is provided with a sealing surface 1 for sealing the metal outer pipe port and a sealing surface 2 for sealing the non-metal pipe port. The plug is formed by two cylinders with different diameters fixed coaxially. The cylinder with a larger diameter is in direct contact with the inner wall of the pipe cap, and the outer ring wall of the cylinder with a larger diameter forms a sealing surface 1. The cylinder with a smaller diameter is connected to the cylinder with a larger diameter, and the outer ring wall of the cylinder with a smaller diameter forms a sealing surface 2.

[0006] When the pipe cap is sleeved on the end of the metal outer pipe, the first sealing surface is inserted and pressed against the end of the metal outer pipe, and the second sealing surface is inserted and pressed against the end of the non-metal pipe. At the same time, the plug keeps the metal outer pipe and the non-metal pipe in a concentric sleeve state.

[0007] Preferably, a sealing gasket is sleeved on the first sealing surface and the second sealing surface, and a plurality of convex ring structures are evenly distributed on the outer surface of the sealing gasket.

[0008] Preferably, an extrusion surface is provided on the side wall of the end of the plug away from the pipe cap. After the plug is sleeved on the inner wall of the non-metallic tube, an annular groove with a V-shaped cross-section is formed between the extrusion surface and the non-metallic tube. A rubber pad is sleeved on the extrusion surface, and the outer ring of the rubber pad contacts the inner wall of the non-metallic tube. A bolt rod is penetrated through the pipe cap and the plug, and a nut is engaged with the outer end of the bolt rod through a thread. The inner end of the bolt rod is connected to an extrusion plate for extruding the rubber pad, and the diameter of the extrusion plate is equal to or smaller than the inner hole diameter of the non-metallic tube, so that the extrusion plate can be placed inside the non-metallic tube.

[0009] Preferably, an insulating sleeve is sleeved on the outer end of the bolt rod and the nut. The insulating sleeve is made of insulating material and can effectively isolate the electrical connection between the bolt rod, the nut and the external environment to prevent safety accidents caused by leakage.

[0010] Preferably, any bolt rod is connected with a conductive plate for electrically connecting an external power source to the non-metallic tube, the conductive plate is sleeved on the bolt rod, and by tightening the nut, the conductive plate is clamped between the nut and the tube cap.

[0011] Preferably, air pipe joints are provided on the side walls of the two pipe caps, and both air pipe joints are connected to the radial gap between the metal outer tube and the non-metallic tube, and one air pipe joint serves as an ozone exhaust port and the other air pipe joint serves as a gas inlet.

[0012] Preferably, an annular air groove is provided inside the metal outer tube, through holes connected to the radial gap are evenly opened on the side walls of the air groove, and the inner end of the air pipe joint is connected to the air groove, so there is no need to limit the installation angle of the pipe cap and the metal outer tube, which facilitates the installation of the pipe cap and the metal outer tube.

[0013] Preferably, the non-metallic tube is made of glass.

[0014] Compared with existing technologies:

[0015] 1. The utility model sleeves the end of the metal outer tube through the tube cap, and the first sealing surface is inserted and pressed against the end of the metal outer tube, and the second sealing surface is inserted and pressed against the end of the non-metallic tube, which plays a role of fixing and sealing, so that the metal outer tube and the non-metallic tube are stably connected together. At the same time, the plug stably maintains the metal outer tube and the non-metallic tube in a concentric sleeve state, ensuring that the discharge gap between the tubes is uniform, thereby ensuring the discharge effect and effectively improving the ozone production.

[0016] 2. In the utility model, by rotating the nut, the bolt rod gradually moves outward, pulling the extrusion plate to apply pressure in the direction of the rubber pad. The pressure causes the rubber pad to deform and fit more closely to the inner wall of the non-metallic tube, thereby achieving relative fixation of the non-metallic tube and the plug. While the metal tube and the plug are relatively fixed, since the plug is fixed on the pipe cap, and the pipe cap is sleeved on the end of the metal outer tube, when the non-metallic tube and the plug are relatively fixed, the metal outer tube is also fixed. This fixing method ensures the stability and sealing of the entire ozone generator structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0024] Example 1

[0025] like Figure 1-Figure 5 As shown, in this embodiment, a tubular ozone generator is provided, comprising a metal outer tube 1, each of the two ends of the metal outer tube 1 is sleeved with a tube cap 2 for fixing and installing, a non-metallic tube 3 is concentrically sleeved inside the metal outer tube 1, and a radial gap exists between the metal outer tube 1 and the non-metallic tube 3;

[0026] A plug 4 is fixed on the inner wall of each pipe cap 2. Figure 3As shown, the plug block 4 is fixed to the pipe cap 2 by a screw 13, and the outer wall of the plug block 4 is provided with a sealing surface 1 401 for sealing the end of the metal outer pipe 1 and a sealing surface 2 402 for sealing the end of the non-metallic pipe 3, as shown in FIG. Figure 2-Figure 5 As shown, the plug 4 is formed by two cylinders with different diameters fixed coaxially, the cylinder with a larger diameter is in direct contact with the inner wall of the pipe cap 2, the outer ring wall of the cylinder with a larger diameter forms a sealing surface 1 401, and the cylinder with a smaller diameter is connected to the cylinder with a larger diameter, the outer ring wall of the cylinder with a smaller diameter forms a sealing surface 2 402;

[0027] When the pipe cap 2 is sleeved on the end of the metal outer pipe 1, the sealing surface 1 401 is inserted and pressed against the end of the metal outer pipe 1, and the sealing surface 2 402 is inserted and pressed against the end of the non-metal pipe 3. At the same time, the plug 4 keeps the metal outer pipe 1 and the non-metal pipe 3 in a concentric sleeve state.

[0028] The pipe cap 2 and the plug block 4 play a role of fixing and sealing. The pipe cap 2 stably connects the metal outer tube 1 and the non-metallic tube 3 together, while the sealing surface 1 401 and the sealing surface 2 402 on the plug block 4 ensure the sealing of the structure to prevent leakage.

[0029] like Figure 2-Figure 5 As shown, in order to increase the sealing performance of the sealing surface 1 401 and the sealing surface 2 402, a sealing gasket is sleeved on the sealing surface 1 401 and the sealing surface 2 402, and a plurality of convex ring structures are evenly distributed on the outer surface of the sealing gasket;

[0030] The design of the sealing gasket can increase the contact area and reduce the possibility of leakage. At the same time, its softness and elasticity can compensate for the small gap caused by changes in factors such as assembly. The setting of the convex ring structure can increase the friction between the sealing gasket and the metal outer tube 1 or the non-metallic tube 3, making the seal more secure. At the same time, the convex ring structure can also produce a certain deformation when subjected to pressure, filling and compensating for the unevenness or small gap of the tube end surface, thereby further improving the sealing performance;

[0031] It can not only improve the sealing performance of the ozone generator and prevent ozone leakage, but also extend the service life of the equipment and reduce the equipment failure rate.

[0032] The non-metallic tube 3 is made of glass.

[0033] Example 2

[0034] like Figure 4-Figure 5As shown, on the basis of Example 1, in order to further relatively fix the metal outer tube 1 and the non-metallic tube 3 on the pipe cap 2 and the plug block 4, an extrusion surface 5 is provided on the side wall of the end of the plug block 4 away from the pipe cap 2. After the plug block 4 is sleeved on the inner wall of the non-metallic tube 3, a ring groove with a V-shaped cross section is formed between the extrusion surface 5 and the non-metallic tube 3. A rubber pad 6 is sleeved on the extrusion surface 5, and the outer ring of the rubber pad 6 contacts the inner wall of the non-metallic tube 3. A bolt rod 7 is penetrated through the pipe cap 2 and the plug block 4, and a nut 8 is meshed with the outer end of the bolt rod 7 through a thread, and an extrusion plate 9 for extruding the rubber pad 6 is connected to the inner end of the bolt rod 7. The diameter of the extrusion plate 9 is equal to or smaller than the inner hole diameter of the non-metallic tube 3, so that the extrusion plate 9 can be placed inside the non-metallic tube 3;

[0035] The fixing principle of the metal outer tube 1 and the non-metallic tube 3 to the tube cap 2 and the plug 4 mainly relies on the coordinated action of the bolt rod 7, the nut 8 and the extrusion plate 9, combined with the deformation effect of the rubber pad 6, to achieve the fixing function;

[0036] First, the plug 4 is fixed on the inner wall of the pipe cap 2, and then the bolt rod 7 passes through the reserved holes at the center of the pipe cap 2 and the plug 4 until its inner end is connected with the extrusion plate 9. At this time, the rubber pad 6 has been sleeved on the extrusion surface 5 of the plug 4, and its outer ring is in contact with the inner wall of the non-metallic pipe 3;

[0037] Then, the nut 8 is screwed onto the outer end of the bolt rod 7, and as the nut 8 rotates, the bolt rod 7 gradually moves outward (eg, Figure 5 As shown, the bolt rod 7 moves to the left relative to the pipe cap 2 and the plug 4), pulling the extrusion plate 9 to apply pressure in the direction of the rubber pad 6, and the pressure causes the rubber pad 6 to deform and fit more closely to the inner wall of the non-metallic pipe 3, thereby achieving relative fixation of the non-metallic pipe 3 and the plug 4. While the non-metallic pipe 3 and the plug 4 are relatively fixed, since the plug 4 is fixed on the pipe cap 2, and the pipe cap 2 is sleeved on the end of the metal outer pipe 1, when the non-metallic pipe 3 and the plug 4 are relatively fixed, the metal outer pipe 1 is also fixed accordingly. This fixing method ensures the stability and sealing of the entire ozone generator structure;

[0038] The tightening action of the bolt rod 7 and the nut 8 also ensures the stable position of the plug 4 in the pipe cap 2, preventing it from moving or loosening during use;

[0039] An insulating sleeve 10 is sleeved on the outer end of the bolt rod 7 and the nut 8. The insulating sleeve 10 is made of insulating material and can effectively isolate the electrical connection between the bolt rod 7, the nut 8 and the external environment to prevent safety accidents caused by leakage.

[0040] Any bolt rod 7 is connected with a conductive plate 11 for electrically connecting an external power source to the non-metallic tube 3. The conductive plate 11 is sleeved on the bolt rod 7. By tightening the nut 8, the conductive plate 11 is clamped between the nut 8 and the tube cap 2.

[0041] The conductive plate 11 connected to any bolt rod 7 is responsible for electrically connecting the external power supply to the non-metallic tube 3. The design of the conductive plate 11 allows current to pass through, thereby entering the non-metallic tube 3 along the bolt rod 7 to provide the necessary electrical energy for ozone generation.

[0042] Example 3

[0043] like Figure 1 , Figure 2 As shown, on the basis of Example 1, in order to provide sufficient ozone output, the side walls of the two pipe caps 2 are provided with air pipe joints 12, and the two air pipe joints 12 are communicated with the radial gap between the metal outer tube 1 and the non-metallic tube 3, and one air pipe joint 12 is used as an ozone exhaust port, and the other air pipe joint 12 is used as a gas inlet;

[0044] A tracheal joint 12 is used as an ozone outlet. Its main function is to allow the ozone generated between the metal outer tube 1 and the non-metallic tube 3 to flow out through the radial gap and be transported to the place where ozone is needed, so that the ozone generated can be effectively utilized to meet the needs of disinfection, purification, etc.

[0045] Another air pipe connector 12 serves as a gas inlet port, and its function is to introduce external gas, such as air or oxygen, into the radial gap between the metal outer tube 1 and the non-metallic tube 3. These external gases produce ozone by ionization under the action of the high-voltage electric field. Therefore, the existence of the gas inlet port ensures that the ozone generator can work continuously and stably and provide sufficient ozone output.

[0046] An annular air groove 101 is provided inside the metal outer tube 1, and through holes 102 communicating with the radial gap are evenly opened on the side wall of the air groove 101, and the inner end of the air pipe joint 12 is communicated with the air groove 101, and there is no need to limit the installation angle of the pipe cap 2 and the metal outer tube 1, which facilitates the installation of the pipe cap 2 and the metal outer tube 1;

[0047] The gas groove 101 is an annular space surrounding the metal outer tube 1. Its existence enables the gas to form a continuous flow path inside the metal outer tube 1, and the through holes 102 are evenly distributed on the side wall of the gas groove 101. They are connected with the radial gap between the metal outer tube 1 and the non-metallic tube 3, so that the gas in the gas groove 101 can smoothly enter the radial gap through the through holes 102 (or enter the gas groove 101 from the radial gap), thereby realizing effective gas circulation;

[0048] In addition, the inner end of the air pipe joint 12 is in communication with the air groove 101, so that the air pipe joint 12 can directly allow external air to flow through the air groove 101 and the radial gap, thereby improving the efficiency of air circulation;

[0049] Due to the connection method between the air pipe joint 12 and the air groove 101, the installation angle between the pipe cap 2 and the metal outer tube 1 does not need to be limited. No matter how the pipe cap 2 is installed, as long as the air pipe joint 12 is connected to the air groove 101, effective flow of gas can be achieved, which greatly simplifies the installation process and improves the flexibility and convenience of installation.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
