[0022] As shown in Figure 1 The ultraviolet sterilizer for seawater disinfection comprises a cavity pipe 1, an inlet and outlet water interface 3, a reducing tee pipe 2, an inlet and outlet water connecting pipe 10, the inlet and outlet water interface 3, a sealing plate 4 and a sealing assembly.

[0023] The cavity pipe 1 is made of PVC material, and a quartz sleeve is mounted in the cavity pipe 1. An ultraviolet lamp is arranged in the quartz sleeve. The reducing tee pipe 2 is connected to both sides of the cavity pipe 1. The sealing plate 4 is mounted on the side of the reducing tee pipe 2 away from the cavity pipe 1. The sealing plate 4 is connected to the sealing assembly on the side away from the cavity pipe 1. The reducing tee pipe 2 is connected to the inlet and outlet water interface 3 through the inlet and outlet water connecting pipe 10.

[0024] Specifically, the quartz sleeve is mounted in the cavity pipe 1 at both ends. The ultraviolet lamp is arranged in the quartz sleeve. The reducing tee pipe 2 is connected to the outer side wall of the quartz sleeve. The sealing plate 4 is mounted on the opening of the reducing tee pipe 2 away from the cavity pipe 1 to achieve the sealing effect. The sealing plate 4 is connected to the sealing assembly to achieve the sealing effect. The third opening of the reducing tee pipe 2 is connected to the inlet and outlet water connecting pipe 10, and the inlet and outlet water connecting pipe 10 is connected to the inlet and outlet water interface 3.

[0025] The ultraviolet sterilizer in the embodiment works as follows: seawater flows through the water inlet and outlet interface 3 on one side, the water inlet and outlet connecting pipe 10, and the reducing tee pipe 2 into the cavity pipe 1, and is sterilized by the ultraviolet light in the quartz sleeve in the cavity pipe 1 when passing through the inside of the cavity pipe 1. After sterilization, the seawater flows out from the reducing tee pipe 2 on the other side, the water inlet and outlet connecting pipe 10, and the water inlet and outlet interface 3 in sequence, so that the ultraviolet sterilizer purifies and sterilizes the seawater.

[0026] The quartz sleeve can be screw-installed by being provided with screw holes at both ends of the cavity pipe 1. The installation and arrangement of the quartz sleeve and the built-in ultraviolet light in the quartz sleeve are conventional technologies, and thus the specific installation method is not described herein. The sealing plate 4 can be fixedly installed by being sleeved with the reducing tee pipe 2 provided with threads on the outer sidewall and corresponding screw holes on the inner sidewall. The water inlet and outlet connecting pipe 10 can be fixedly connected with the reducing tee pipe 2 and the water inlet and outlet interface 3 by bolt connection, interference fit connection, or the like.

[0027] In the embodiment, the cavity pipe 1 is made of PVC material. The PVC material is non-toxic, odorless, and odorless, has excellent resistance to most household and industrial chemicals, can resist strong oxidizing agents, acids, bases, salts, and organic solvents, and is not hygroscopic and has good water vapor resistance, and thus can be used for moisture-proof and anti-seepage purposes. Therefore, the PVC material is very suitable for the cavity pipe 1 of the ultraviolet sterilizer for disinfecting seawater, and can effectively prevent water leakage. In addition, the reducing tee pipe 2 is used to butt joint with the water inlet and outlet connecting pipe 10, the water inlet and outlet interface 3, and the sealing plate 4, instead of using glue to seal or fixedly connect, which can effectively improve the stability of the butt joint and eliminate the problems of incomplete glue connection or glue aging, thereby further preventing water leakage and improving product quality.

[0028] In an alternative embodiment, the sealing assembly includes a sealing plate sleeve 5, an O-shaped sealing ring 9, and a sleeve sealing nut 8.

[0029] The sealing plate 4 is provided with a mounting hole in which the sealing plate sleeve 5 is fixedly installed. The sealing plate sleeve 5 is connected with the O-shaped sealing ring 9 and the sleeve sealing nut 8.

[0030] One end of the quartz sleeve enters the reducing tee pipe 2 and the cavity pipe 1 in sequence through the mounting hole, and the other end of the quartz sleeve is sealed and fixed through the sealing plate sleeve 5, the O-shaped sealing ring 9, and the sleeve sealing nut 8 in sequence.

[0031] Specifically, the installation of the whole sealing assembly can be realized by opening the mounting hole in the sealing plate 4, fixing the sealing plate sleeve 5 in the mounting hole through sleeve fitting, then sleeving the O-shaped sealing ring 9, and finally screwing the sleeve sealing nut 8, so that good sealing effect can be achieved at the opening of the reducing tee pipe 2 away from the cavity pipe 1, preventing seawater from leaking from the side of the reducing tee pipe 2 and affecting the purification and sterilization effect of seawater. Moreover, the sealing of the quartz sleeve at both ends by the sealing plate sleeve 5, the O-shaped sealing ring 9 and the sleeve sealing nut 8 can improve the sealing performance of the quartz sleeve.

[0032] In the embodiment, the stability of the butt joint is effectively improved by adopting the reducing tee pipe 2, the water inlet and outlet connecting pipe 10, the water inlet and outlet interface 3 and the sealing plate 4 for butt joint, and sealing by the sealing plate sleeve 5, the O-shaped sealing ring 9 and the sleeve sealing nut 8 in turn, instead of the scheme of sealing or fixed connection by using glue, so that the problems of incomplete glue connection or glue aging are eliminated, the water leakage is further avoided, and the product quality is improved.

[0033] In an alternative embodiment, the sealing plate 4 is connected with a sealing plate pressing piece 7 away from the cavity pipe 1.

[0034] Specifically, the sealing plate pressing piece 7 can be installed by directly sleeving and screwing with the sealing plate pressing piece 7, and the sealing plate sleeve 5, the O-shaped sealing ring 9 and the sleeve sealing nut 8 are accommodated between the sealing plate 4 and the sealing plate pressing piece 7. Therefore, when assembling the ultraviolet sterilizer, the sealing plate pressing piece 7, the sealing plate 4 and the sealing assembly can be installed in the reducing tee pipe 2 by first installing the sealing plate pressing piece 7 and the sealing plate 4 and the sealing assembly, and then rotating the sealing plate pressing piece 7.

[0035] In the embodiment, when it is necessary to install or replace the quartz sleeve, the sealing plate 4 can be twisted out of the reducing tee pipe 2 by rotating the sealing plate pressing piece 7, and then the quartz sleeve can be taken out or inserted from the opening of the reducing tee pipe 2 connected with the sealing plate 4. After the quartz sleeve is inserted, the quartz sleeve is fixedly connected with the cavity pipe 1 and the sealing plate 4 and the sealing assembly on the other side by rotating the quartz sleeve, so that the installation of the quartz sleeve can be completed. Therefore, the embodiment can facilitate the assembly of the whole ultraviolet sterilizer and the replacement and installation of the quartz sleeve and ultraviolet light.

[0036] In an alternative embodiment, the cavity pipe 1 is symmetrically connected with a cavity pipe support frame 6 on the outer side wall.

[0037] Specifically, the cavity tube support frame 6 can be a support frame provided with an annular mounting groove, which is mounted by sleeving the annular mounting groove on the outer sidewall of the cavity tube 1. The cavity tube 1 is symmetrically connected with the cavity tube support frame 6 on the outer sidewall, which can fix and support the cavity tube 1 to prevent the ultraviolet sterilizer from shaking and moving when seawater passes through the cavity tube 1.

[0038] In an alternative embodiment, the inner wall of the cavity tube 1 is provided with a reflection cover capable of reflecting ultraviolet rays.

[0039] Specifically, by arranging the reflection cover capable of reflecting ultraviolet rays on the inner wall of the cavity tube 1, the reflection cover can reflect the ultraviolet rays generated by the ultraviolet lamp, so that the seawater is sterilized after being reflected, thereby facilitating the enhancement of the sterilization effect. The reflection cover can be installed by means of bolts and the like.

[0040] In an alternative embodiment, the quartz sleeve and the ultraviolet lamp are provided in plurality and are arranged in circumferential uniform interval from the side.

[0041] Specifically, by arranging the plurality of quartz sleeves and ultraviolet lamps in circumferential uniform interval, the sterilization quality and the sterilization effect can be further improved, and the seawater passing through the cavity tube 1 can be ensured to have uniform sterilization effect.
