[0034] Please see Figures 1-3 This utility model discloses a centralized water supply device for a printing press, including a water storage tank 1 and a water supply tank 2;

[0035] The upper end of the water storage tank 1 is equipped with a first water tank cover 3;

[0036] A second water tank cover 4 is installed on the upper end of the water supply tank 2;

[0037] The first water tank cover 3 has an inlet and a drain, and an inlet pipe 5 is installed at the inlet.

[0038] It also includes a drain pipe 6, one end of which passes through the drain outlet and extends into the bottom of the water storage tank 1, and the other end of which passes through the second water tank cover 4 and extends into the bottom of the water supply tank 2; a drain pump 22 is installed inside the water storage tank 1, and the outlet end of the drain pump 22 is connected to the drain pipe 6; a water outlet pump 23 is installed inside the water supply tank 2, and the outlet end of the water outlet pump 23 is connected to the water supply pipe 7.

[0039] A water supply pipe 7 is installed on one side of the bottom end of the water supply tank 2. A flow regulating valve 11 is also installed on the water supply pipe 7. A water quality filtration assembly 8 is also installed inside the water supply tank 2.

[0040] In this invention, the water filtration assembly 8 includes a mesh frame 9 and a filter element layer 10. The filter element layer 10 is installed inside the mesh frame 9 and includes a non-woven fabric folded layer 12, a fiber activated carbon layer 13, a polypropylene skeleton 14, and an ultrafiltration membrane 15. The fiber activated carbon layer 13 is disposed inside the non-woven fabric folded layer 12 and is tightly fitted to it. The polypropylene skeleton 14 is disposed inside the fiber activated carbon layer 13 and is tightly fitted to it. The ultrafiltration membrane 15 is disposed inside the polypropylene skeleton 14 and is tightly fitted to it. The fiber activated carbon layer in this water filtration assembly effectively removes residual chlorine and adsorbs volatile organic compounds. The ultrafiltration membrane has a filtration accuracy of 0.01µm, effectively removing harmful substances such as colloids, bacteria, viruses, and large molecular organic matter from the water. It is permanently hydrophilically modified, resistant to fouling and clogging, small in size, and has a high flow rate. The water filtration assembly has a multi-stage filtration function, ensuring that the water quality meets the requirements for printing press water.

[0041] In this invention, a low water level sensor 16 and a high water level sensor 17 are respectively installed on the inner wall of the water storage tank 1. The low water level sensor 16 and the high water level sensor 17 are respectively connected to an external controller 18, and the controller 18 is electrically connected to an electromagnetic valve 19 installed on the water inlet pipe 5. This allows for real-time feedback of the low and high water levels in the water storage tank, achieving automatic water replenishment.

[0042] In addition, this utility model also includes a water quality monitoring sensor 20, which is installed at the bottom of the water supply tank 2. The water quality monitoring sensor 20 is electrically connected to a controller 18, and the controller 18 is connected to a display screen 21 installed on the outer wall of the water supply tank 2. The water quality monitoring sensor collects the water quality of the filtered water in real time and displays it on the display screen. If an abnormal water quality is detected, an alarm signal is immediately issued and the water supply is stopped.

[0043] Working principle: External water enters the water storage tank through the inlet pipe. When the water level in the tank reaches the high water level sensor, the high water level sensor sends a high water level signal and closes the solenoid valve through the controller to stop the water supply. The controller then controls the drain pump to work, which pumps the water in the storage tank into the supply tank. The water is filtered through the water quality filtration component. At the same time, the outlet pump is turned on, which pumps the filtered water into the supply pipe and supplies it to the printing press.

[0044] In summary, this utility model has a novel structural design and is easy to operate. It can realize the functions of automatic water replenishment and supply, and can also filter water quality to ensure the working performance of the printing press.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
