Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cooling water tank structure used on an irradiator. Background Art

[0002] X-ray biological irradiator is an analytical instrument used in the fields of biology, basic medicine, and pharmacy. It is mainly used in cancer biology, human genome, induced gene changes, stem cells, small animal irradiation, cell culture and division inhibition research, research on TB cells and blood cells, bone marrow transplant irradiation, transplant immunity, immunosuppressive therapy, radiation sensitivity research, DNA damage research, food irradiation, microbial inactivation, plant and seed irradiation, etc.

[0003] The irradiator houses a tube that generates X-rays to irradiate the material within. The tube requires power and cooling, typically using water. Therefore, the irradiator is equipped with a water tank. The tube is a precision device, so the cooling water must be carefully filtered before entering it. This filter is typically located within the water tank. The output of the filter is a rigid tube that passes through the side of the water tank and forms a connector on the outside. This connector connects to a hose that delivers the cooling water.

[0004] In a structure where a rigid tube penetrates the side wall of a water tank, two requirements must be met: first, the tube must be fixed to the water tank, and second, a seal must be maintained between the tube and the water tank to prevent cooling water from overflowing from the penetration point. In the prior art, the rigid tube is provided with external threads at the end outside the water tank, and the joint is provided with internal threads. The joint is threadedly connected to the rigid tube, and the joint is glued to the side wall of the water tank to achieve the dual effects of fixation and sealing. However, this glued connection method has poor stability and the joint is prone to falling off, which poses a significant risk when used in medical devices with high stability requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling water tank structure, which can effectively fix and seal the joints of the water tank and is particularly suitable for application on irradiators with high stability requirements.

[0006] The technical solution of the utility model is:

[0007] A cooling water tank structure for an irradiator includes a square water tank and a filter device. The output end of the filter device is a hard pipe that passes through the side wall of the water tank. A joint is provided on the outside of the water tank. The joint includes a joint seat and a nozzle. The hard pipe and the joint seat are threadedly connected. The joint seat and the water tank are connected by screws. An O-ring is provided between the side wall of the water tank and the joint seat.

[0008] The utility model provides a joint on the outside of the water tank, which is threadedly connected to the filter's hard pipe and fixed to the water tank with screws, effectively achieving the requirement of fixed connection between the hard pipe and the water tank. The provision of an O-ring also achieves a seal at the point where the hard pipe penetrates, preventing cooling water in the water tank from overflowing from the penetration point.

[0009] In an optional embodiment of the present invention, the screw holes on the side wall of the water tank are blind holes. Compared with through screw holes, this can prevent cooling water from overflowing from the through holes, but requires the water tank to have a larger wall thickness for setting the blind holes.

[0010] In another optional embodiment of the present invention, the screw passes through the side wall of the water tank, and screw glue is provided between the screw and the side wall of the water tank.

[0011] In this solution, the sealing problem at the screw hole is solved by screw glue, which reduces the requirement for the water tank wall thickness when setting blind holes.

[0012] The outer side of the nozzle is provided with anti-slip corrugations.

[0013] The advantages and positive effects of the utility model are: due to the adoption of the above technical solution, while ensuring the filtering performance of the water tank, the fixation and sealing problems between the water outlet end of the filtering device and the water tank wall are solved, and the stability and processing convenience of the equipment are improved.
