Description

Technical Field

[0001] This utility model relates to the field of ultraviolet irradiation device technology, specifically to a nadroparin calcium ultraviolet irradiation device. Background Technology

[0002] Nadroparin calcium is a novel antithrombotic drug. In the preparation of nadroparin calcium, one of the steps is to irradiate the nadroparin calcium solution with ultraviolet light. This is because the nadroparin calcium solution contains a large number of N-NO groups and nitrosamines. Irradiating the reducing solution with ultraviolet light can eliminate the residual nitrosamines in the reducing solution and reduce the content of N-NO groups.

[0003] For example, the ultraviolet irradiation device proposed in document CN117160386A, which can be used for impurity removal after the degradation of nadroparin calcium or dalteparin sodium, has an ultraviolet irradiation lamp placed inside a reaction vessel. The irradiated solution is contained inside the vessel, and the solution is in direct contact with the ultraviolet lamp. However, the solution contains a variety of components, and during use, various substances in the solution adhere to the surface of the ultraviolet irradiation lamp. Once these substances adhere to the surface of the ultraviolet irradiation lamp, they cannot be removed, which reduces the intensity of the ultraviolet light emitted by the lamp and thus affects the irradiation effect on the solution. Therefore, we propose an ultraviolet irradiation device for nadroparin calcium. Utility Model Content

[0004] This invention provides a nadroparin calcium ultraviolet irradiation device, which has the advantage of keeping the surface of the ultraviolet light tube inside the tank clean at all times, thus solving the problems mentioned in the background art.

The elastic dust removal ring is in elastic contact with the surface of the ultraviolet lamp, and the collar is connected to the annular seat. At least one guide rod is symmetrically arranged on the edge of the annular seat. The top of the guide rod is movably mounted on the sealing cover, and the top of the guide rod is connected to a lifting mechanism.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 8This utility model provides a technical solution: a nadroparin calcium ultraviolet irradiation device, including a tank 1, a first support leg 16 at the bottom of the tank 1, and a sealing cover 2 at the top of the tank 1. The sealing cover 2 is connected to the top of the tank 1 by bolts or a lock. The top of the sealing cover 2 has an inlet 10 and an observation port 3. There is at least one inlet 10, which is used to introduce the nadroparin calcium reaction solution into the tank. The top of the observation port 3 is sealed by a cover plate, which is connected to the observation port 3 by bolts or a lock. A drain valve 15 is provided at the bottom of the tank 1. In actual use, the nadroparin calcium solution is introduced into the tank 1 through the inlet 10. The nadroparin calcium solution is irradiated with ultraviolet light inside the tank 1. After irradiation, the solution is discharged from the bottom of the drain valve 15.

[0026] A support ring 22 is provided at the top of the tank body 1. The support ring 22 is coaxial with the tank body 1 and is installed below the sealing cover 2. Specifically, multiple supports 23 are installed on the top edge of the support ring 22. The top of the supports 23 is connected to the bottom of the sealing cover 2, and the supports 23 are connected to the sealing cover 2 by bolts. This allows the support ring 22 to be firmly fixed below the sealing cover 2. like Figure 4 and Figure 5 As shown, multiple ultraviolet lamps 20 are vertically installed at the bottom of the support ring 22, and the ultraviolet lamps 20 are arranged in a ring along the bottom of the support ring 22. For example, Figure 5 As shown, all the ultraviolet lamp tubes 20 are located inside the annular seat 19. In other words, an annular seat 19 is fitted outside the space enclosed by the ultraviolet lamp tubes 20. The annular seat 19 is coaxially arranged with the support ring 22. It is important to emphasize that each ultraviolet lamp tube 20 is movably fitted with a collar 26, allowing each collar 26 to move freely back and forth along the axis of the ultraviolet lamp tube 20. Each collar 26 is equipped with an elastic dust removal ring coaxially arranged with the ultraviolet lamp tube 20. The elastic dust removal ring is in elastic contact with the surface of the ultraviolet lamp tube 20, and the collar 26 is connected to the ring seat 19. Specifically, one side of the collar 26 is fastened to the ring seat 19 with bolts. When the ring seat 19 moves up and down, it can simultaneously drive each collar 26 to move along the ultraviolet lamp tube 20. Since the ultraviolet lamp tube 20 has a cylindrical structure, the elastic dust removal ring can fully contact the surface of the ultraviolet lamp tube 20. When the elastic dust removal ring moves up and down with the ring seat 19, it removes the adhering substances on the surface of the ultraviolet lamp tube 20, preventing the ultraviolet lamp tube 20 from having adhering substances on its surface, which would reduce the light intensity.

[0027] Furthermore, the up-and-down movement of the annular seat 19 along the ultraviolet lamp tube 20 requires the drive of the guide rod 5. That is, at least one guide rod 5 is symmetrically provided on the edge of the annular seat 19. In actual use, there are two guide rods 5 and they are symmetrically arranged. The top of the guide rod 5 is movably mounted on the sealing cover 2. A sealing component is provided between the sealing cover 2 and the guide rod 5 to prevent outside air from entering the tank 1 when the guide rod 5 moves up and down. The top of the guide rod 5 is connected to the lifting mechanism. Driven by the lifting mechanism, the guide rod 5 moves up and down inside the sealing cover 2, thereby allowing the guide rod 5 to drive the annular seat 19 to move up and down along the ultraviolet lamp tube 20. It should be noted that the annular seat 19 only moves up and down along the ultraviolet lamp tube 20, so that the collar 26 will not fall off the ultraviolet lamp tube 20. Because the ultraviolet lamp tube 20 is relatively long, matching the internal length of the tank 1, its bottom is mounted on the reinforcing ring 21 to ensure stability and prevent bending. Figure 7 As shown, the reinforcing ring 21 and the support ring 22 are connected by reinforcing rods 24. There are at least two reinforcing rods 24, which are symmetrically arranged. The reinforcing ring 21, the support ring 22 and the reinforcing rods 24 constitute the skeleton that supports the ultraviolet lamp tube 20, so that the ultraviolet lamp tube 20 is stably supported.

[0028] Based on the above embodiments, when the ultraviolet lamp tube 20 emits light, the light from the ultraviolet lamp tube 20 will fill the entire tank 1. However, in order to allow the nadrone calcium solution to have better contact with the light, a drive motor 4 is installed in the middle of the top surface of the sealing cover 2. The drive motor 4 is connected to the stirring shaft 27. Multiple stirring blades are provided on the stirring shaft 27. The ultraviolet lamp tube 20 is distributed around the stirring shaft 27, and the ultraviolet lamp tube 20 does not contact the stirring blades to prevent them from touching. The bottom of the stirring shaft 27 is provided with a spiral blade 25, which extends to the bottom of the tank 1. When the stirring shaft 27 rotates with the drive motor 4, the stirring blade will stir the solution around the ultraviolet lamp tube 20, allowing the solution to flow around the ultraviolet lamp tube 20. The spiral blade 25 can lift the solution from the bottom of the tank 1, which not only increases the fluidity in the tank, but also the rising liquid flow driven by the spiral blade 25 impacts the stirring blade, which can further increase the degree of liquid tumbling.

[0029] Furthermore, such as Figure 1 and Figure 2As shown, the lifting mechanism includes a mounting platform 12 located on one side of the bottom of the tank 1. One side of the mounting platform 12 is connected to the first support leg 16, and a second support leg 13 is also provided at the bottom of the mounting platform 12. A vertical frame 7 extending above the tank 1 is provided on the top of the mounting platform 12. A slide rail 9 is provided on the top side of the vertical frame 7, and a slider 8 is slidably mounted on the slide rail 9. One side of the slider 8 is connected to a horizontal support arm 6. The horizontal support arm 6 is located above the tank 1, and the top of the guide rod 5 is connected to the horizontal support arm 6. A lead screw 17 is also provided on the side of the vertical frame 7. A transmission seat 18 is threaded onto the lead screw 17. The transmission seat 18 is connected to the slider 8. Both ends of the lead screw 17 are rotatably connected to the vertical frame 7. The bottom of the lead screw 17 is connected to the adjusting motor 14. The adjusting motor 14 is installed on the mounting platform 12. Therefore, when the adjusting motor 14 rotates, it can drive the lead screw 17 to rotate. The rotating lead screw 17 can drive the horizontal support arm 6 to move up and down along the slide rail 9, thereby driving the guide rod 5 to extend and retract up and down inside the sealing cover 2.

[0030] Based on the above embodiments, this application also includes a control cabinet 11, which is equipped with a controller. The controller is electrically connected to the regulating motor 14, the drive motor 4, and the ultraviolet lamp tube 20. The controller can control each component to travel according to a set path, so that the whole equipment can be automated. That is, the controller controls the regulating motor 14 to rotate, and the regulating motor 14 drives the guide rod 5 to move up and down, thereby causing the guide rod 5 to move the ring seat 19 up and down.

[0031] Based on the above embodiments, it should be further explained that the elastic dust removal ring is installed on the upper and lower end faces of the collar 26, or a sealing groove can be provided on the inner wall of the collar 26, and the elastic dust removal ring can be installed in the sealing groove.

[0032] Based on the above embodiments, further optimization can be achieved by providing a grating ruler connected to the slider 8 on the top side of the vertical frame. The grating ruler is connected to a controller and can accurately measure the displacement of the slider 8 moving up and down, thus accurately controlling the linear displacement of the ring seat 19 moving up and down.

[0033] Based on the above embodiments, it should be further explained that the outer shell of the ultraviolet lamp tube 20 is a transparent glass structure, and the connection point between the top of the ultraviolet lamp tube 20 and the wire needs to be sealed. In addition, multiple wires pass through the wire hole at the top of the sealing cover, and the wire hole also needs to be sealed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
