Description

Technical Field

[0001] The present application relates to the technical field of ultraviolet inactivation devices, and in particular to a sealing installation structure of an ultraviolet inactivation device. Background Art

[0002] Ultraviolet inactivation device, also known as ultraviolet inactivation reactor, is a device that kills microorganisms through ultraviolet rays. During the ballast water treatment process, the ultraviolet inactivation device can be used to inactivate microorganisms in the ballast water.

[0003] The related art discloses a UV inactivation device, including a treatment box, the lower end of which is connected to a water inlet pipe, and the upper end of which is connected to a water outlet pipe; a mounting hole is provided through the outer wall of the treatment box, a transparent quartz sleeve is inserted into the mounting hole, and the end of the quartz sleeve away from the mounting hole is located inside the treatment box; an ultraviolet lamp is installed in the quartz sleeve, and the ultraviolet lamp is used to emit ultraviolet rays; an annular groove is provided along the circumference of the mounting hole on the inner peripheral wall of the mounting hole, and an O-ring is embedded in the annular groove; the peripheral wall of the O-ring fits the outer peripheral wall of the quartz sleeve to improve the sealing performance between the quartz sleeve and the mounting hole. After the ballast water is passed into the treatment box through the water inlet pipe, the ultraviolet rays emitted by the ultraviolet lamp can contact the ballast water flowing into the treatment box to inactivate the microorganisms in the ballast water.

[0004] Regarding the above-mentioned related technologies, when installing the quartz sleeve, first insert the quartz sleeve into the corresponding installation hole, and then put the O-ring on the quartz sleeve; finally, insert the O-ring into the installation hole and embed the O-ring in the annular groove. During the installation of the O-ring, when the O-ring is located in the installation hole and the O-ring is located outside the annular groove, the O-ring is in a compressed state; when the O-ring moves into the annular groove, the deformation of the O-ring decreases, and at this time, the O-ring has a deformation margin; when the ballast water contacts the O-ring, the water pressure easily causes the O-ring to deform, resulting in a gap between the O-ring and the inner circumferential wall of the annular groove or the outer circumferential wall of the quartz sleeve, and the sealing effect is poor, so it needs to be improved.

[0008] By adopting the above technical scheme, the connecting part is sealed and connected with the outer side wall of the treatment box of the ultraviolet inactivation device, and the clearance hole is aligned with the corresponding mounting hole; then the quartz sleeve is inserted into the mounting hole through the clearance hole; then the elastic sealing ring is sleeved on the quartz sleeve and one end of the elastic sealing ring close to the mounting hole is embedded in the embedded ring groove; finally, the clamping assembly is installed for the clamping assembly to press the elastic sealing ring so that the elastic sealing ring is elastically deformed, so that the inner circumferential wall of the elastic sealing ring is fitted with the outer circumferential wall of the quartz sleeve, the outer circumferential wall of the elastic sealing ring is fitted with the inner circumferential wall of the embedded ring groove, and the end wall of the elastic sealing ring is fitted with the bottom wall of the embedded ring groove, thereby improving the sealing performance of the connection between the quartz sleeve and the mounting plate to reduce the possibility of leakage of liquid in the treatment box.

[0009] The pressing assembly can press the elastic sealing ring to make it fully deformed, thereby reducing the risk of further deformation of the elastic sealing ring under the action of water pressure, and reducing the possibility of separation of the elastic sealing ring from the outer peripheral wall of the quartz sleeve or the bottom wall of the embedded ring groove.

[0023] By adopting the above technical solution, when the clamping ring plate contacts the elastic sealing ring, the connecting sleeve continues to rotate, and the connecting sleeve can rotate relative to the clamping ring plate so that the clamping ring plate and the elastic sealing ring remain relatively still, thereby reducing the possibility of distortion or wear of the elastic sealing ring, and at the same time helping to reduce the rotational resistance of the connecting sleeve.

[0024] Optionally, a ball bearing is provided between the connecting ring plate and the pressing ring plate, and the connecting ring plate abuts against the pressing ring plate through the ball bearing.
