Description

Technical Field

[0001] The invention relates to the technical field of hemodialysis concentrate production equipment, and in particular to a hemodialysis concentrate configuration device. Background Art

[0002] Most existing hemodialysis concentrate mixing devices use stirring paddles to stir the concentrate, but the stirring blades of the stirring paddles are relatively short, so the stirring radius and stirring area are relatively small, resulting in a relatively small single stirring amount, which affects production efficiency. When the length of the stirring blades is extended, there is a problem that the stirring blades are easily deformed.

[0003] At the same time, the mixing effect will be different due to different water temperatures during the preparation of hemodialysis concentrate. Therefore, it is also necessary to ensure constant control of the water temperature. Summary of the invention

The commutators 183 on two adjacent partition plates 181 are in opposite directions, and the water flow direction can be changed by the commutator 183, that is, one partition plate 181 changes the water flow direction to clockwise, and another adjacent partition plate 181 changes the water flow direction to counterclockwise;

[0021] The bottom of the tank body 180 is also provided with a drug inlet 184;

The upper and lower ends of the liquid storage tank 185 are also connected to a circulation pump 188 through pipelines.

[0023] The first solenoid valve 12, the pressure gauge 13, the flow meter 14, the water pump motor 16, the second solenoid valve 17, the high liquid level sensor 150, the low liquid level sensor 151, the temperature sensor 152, the electric heater 153 and the circulation pump 188 are all electrically connected to the PLC module.

[0026] Furthermore, the liquid discharge pipe 186 and the detection liquid discharge pipe 187 are provided with a filter screen 11.

[0027] The working principle and use process of the present invention:

[0028] When in use, the flange 10 is connected to the external water inlet pipeline, the filter 11 can filter the impurities that may be contained in the water, and the first solenoid valve 12 is opened through the PLC module, and the water enters the water tank 15. At this time, the temperature sensor 152 will detect whether the water temperature inside the water tank 15 is within the preset temperature range. If the temperature is too low, the temperature sensor 152 will give an electrical signal to the PLC module, and the PLC module will give a signal to the electric heater 153. At this time, the electric heater 153 heats the water. When the water height inside the water tank 15 reaches the high liquid level sensor 150, the high liquid level sensor 150 will give an electrical signal to the PLC module, and the PLC module will close the first solenoid valve 12. When the water temperature inside the water tank 15 meets the ratio standard, the PLC module will control the second solenoid valve 17 and The water pump motor 16 works to discharge the water in the water storage tank 15 into the mixing tank 18. At the same time, the liquid medicine is injected into the mixing tank 18 through the medicine inlet 184. The principle of liquid mixing in the mixing tank 18 is as follows: the water in the mixing tank 18 enters from the side wall of the tank body 180 and impacts the side wall of the tank body 180, and performs directional swirl movement inside the tank body 180. When the reaction chamber 4 between the partition plate 181 and the bottom surface of the tank body 180 is filled with the mixed liquid, the mixed liquid enters the adjacent mixing chamber through the water outlet trough 182 on the partition plate 181, and the direction of the water flow is changed counterclockwise by the commutator 183 set on the partition plate 181. After multiple swirl movements, it reacts more fully, and the mixed hemodialysis concentrate is stored in the liquid storage tank 185. The PLC module controls the movement of the circulating pump 188 at a fixed time. The configured hemodialysis concentrate can be sampled and tested through the test liquid discharge pipe 187 to verify whether it meets the production standards.
