DETAILED DESCRIPTION

[0028] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0031] In order to facilitate the removal of impurities after filtration, Figures 1 to 4As shown, it includes: a tank body 1 and a filtering assembly for an iohexol intermediate installed on the inner side of the tank body 1, the filtering assembly includes a partition 2 fixedly inserted in a transverse direction on the inner side of the tank body 1, two connecting pipes 9 are symmetrically inserted at the bottom of the partition 2, and the connecting pipe 9 is installed with a solenoid valve, and the iohexol solution can be discharged to the bottom of the partition 2 by opening the solenoid valve, and a waterproof motor 3 is installed at the bottom center of the partition 2 through a motor seat, and the output end of the waterproof motor 3 passes through the bottom of the partition 2 and is connected to a connecting disk 4, and the waterproof motor 3 drives the connecting disk 4 to rotate to drive the first filter cartridge 6 to rotate.

[0032] The top of the connecting disk 4 supports the first filter cartridge 6, and four plug rods 5 are welded on the top of the connecting disk 4 in a rectangular shape. The bottom of the first filter cartridge 6 is constructed with a slot for accommodating the plug rod 5. The four plug rods 5 cooperate with the corresponding slots to stably fix the first filter cartridge 6. The side wall of the first filter cartridge 6 is evenly provided with a plurality of leakage holes 7. When the first filter cartridge 6 rotates, the first filter cartridge 6 can discharge the iodine hexol solution through the leakage holes 7 by centrifugal force, and large particles of impurities will remain on the inner side of the first filter cartridge 6. Two handles 8 are symmetrically welded on the outer wall of the first filter cartridge 6. The corners of the handles 8 are arc-shaped structures to improve the hand feel. The first filter cartridge 6 can be conveniently lifted and taken out by the handles 9. Two electric heating plates 20 are symmetrically nested and installed on the upper part of the inner wall of the tank body 1. The existing principle can be used for heating to fully dissolve the iodine hexol in water to form a solution.

[0033] An observation window 17 (not drawn transparently in the figure) is nested and installed on one side wall of the tank body 1. The filtering condition of the solution can be observed in real time through the observation window 17. A label 18 is bonded to the outer wall of one side of the tank body 1. Precautions are marked on the surface of the label 18 for the staff to understand. The bottom of the tank body 1 is rectangularly distributed and welded with four legs 19 for supporting the tank body 1. A top cover 16 is hinged on the top of the tank body 1. Iohexol and water can be put in by opening the tank body 1.

[0034] The bottom of the tank body 1 is threadedly connected to the second filter cartridge 10, which can be disassembled and assembled by rotating the second filter cartridge 10. The inner bottom of the tank body 1 is connected to an inclined guide plate 15 corresponding to the second filter cartridge 10 to ensure that impurities and solution can reach the top of the filter screen 11 for filtration. The filter screen 11 is nested on the inner top of the second filter cartridge 10 for filtering the iohexol solution and small particle impurities.

[0035] The side wall of the second filter cartridge 10 is fixedly sleeved with a limit plate 12, and the limit plate 12 abuts against the bottom of the tank body 1 to determine the installation position of the second filter cartridge 10. The bottom of the limit plate 12 is symmetrically connected to two handles 13 by screws. The corners of the handles 13 are arc-shaped structures to improve the hand feel. The handles 13 are used to conveniently apply force to rotate the limit plate 12 to rotate the second filter cartridge 10. The bottom of the second filter cartridge 10 is connected with a discharge pipe 14 equipped with a control valve. The iodine hexol solution can be discharged by opening the discharge pipe 14.

[0036] The waterproof motor 3, the solenoid valve, and the electric heating plate 20 are all set as conventional instruments. The working principle, size, and model are irrelevant to the function of this application, so they are not described in detail, and they are all controlled by a remote control switch.

[0037] How it works

[0038] The filtration device for the iohexol intermediate first connects the electrical components in the device to an external power supply and a remote control switch, puts iohexol and water into the inner side of a first filter cartridge 6, and starts a waterproof motor 3 and an electric heating plate 20. The two electric heating plates 20 can be heated by using an existing principle to fully dissolve iohexol in water to generate a solution. The first filter cartridge 6 is driven by the waterproof motor 3 to continuously rotate. During the rotation, the iohexol solution can be discharged through a leakage hole 7 by centrifugal force, and large particles of impurities will remain in the inner side of the first filter cartridge 6. The solenoid valve is opened to discharge the iohexol solution through a connecting pipe 9 to the bottom of the partition 2.

[0039] The iohexol solution is filtered through the filter 11 and enters the second filter cartridge 10, wherein small particles of impurities are retained on the top of the filter 11. The iohexol solution can be discharged by opening the control valve of the discharge pipe 14, and the power is turned off, and the small particles of impurities can be removed by unscrewing the second filter cartridge 10. The top cover 16 is opened and the first filter cartridge 6 is lifted by the handle 8 to remove the large particles of impurities.
