Description

Technical Field

[0001] The utility model relates to the technical field of purified water filtration, in particular to a filtering component of purified water equipment for pharmaceutical use. Background Art

[0002] Purified water is water that has undergone multiple treatments and filtrations and is commonly used in pharmaceuticals, food, laboratories, and industrial fields. The content of most impurities, microorganisms, ions, and organic matter in purified water is extremely low and meets specific quality standards. Since most dissolved substances have been removed, purified water is usually tasteless and colorless. Under certain conditions, it can maintain the stability of its chemical and physical properties. Due to its high purity and versatility, purified water has a wide range of applications in various fields and is an indispensable resource in many industrial and scientific research activities.

[0003] In the pharmaceutical field, purified water is widely used. Purified water needs to be filtered through a filter assembly during preparation. When the filter assembly is in use, the filter element needs to be regularly disassembled for replacement or cleaning. In order to maintain the airtightness of the assembly, the fixing structure of the filter element of the general filter assembly is relatively cumbersome. It takes a lot of time for the staff to disassemble the filter element, which greatly reduces the efficiency of the filter element replacement. When filtering water resources with a lot of impurities, the filter element is prone to frequent clogging, the filtering effect of the filter assembly is reduced, the preparation speed of purified water is likely to lag behind the consumption speed, and the pharmaceutical preparation speed is reduced. In response to the above problems, a filter assembly for pharmaceutical purified water equipment is proposed to solve them. Utility Model Content

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] Reference Figure 1-3 As shown, a filtering component of a pharmaceutical purified water equipment includes a shell 1, a sewage pipe 2 is fixedly connected to the center position of the lower side of the shell 1, a first electromagnetic valve 3 is fixedly installed on the sewage pipe 2, and a water inlet pipe 4 is fixedly connected to the upper left end of the shell 1.

[0020] Specifically, the upper side of the shell 1 is fixedly connected with a connecting threaded barrel 5, and the inner upper end of the connecting threaded barrel 5 is threadedly connected with a pressure plate 6, which is convenient for disassembly and replacement of the filter element 10, and the left and right ends of the upper side of the pressure plate 6 are fixedly connected with handles 7, which are convenient for rotating the pressure plate 6. A rectangular clamping block 8 is fixedly connected at the center position of the inner lower side of the shell 1, and arc-shaped sewage outlets 9 are penetrated at the front and back ends of the inner lower side of the shell 1. The lower end of the arc-shaped sewage outlet 9 is connected to the interior of the sewage pipe 2, and the upper end of the rectangular clamping block 8 is clamped with a filter element 10, which effectively filters water resources and prepares purified water. The inner lower end of the connecting threaded barrel 5 is slidably connected with a rubber waterproof pad 11, which effectively ensures the airtightness of the filter assembly, and a first set of interfaces 12 is penetrated at the upper center position of the rubber waterproof pad 11.

[0021] Specifically, a connecting pipe 13 is threadedly connected at the center position of the upper side of the filter element 10, and the surface of the connecting pipe 13 is slidably connected to the inner side of the first sleeve interface 12. A second sleeve interface 14 is opened through the center position of the upper side of the pressure plate 6, and the surface of the connecting pipe 13 is slidably connected to the inner side of the second sleeve interface 14. A rectangular slot 15 is opened on the lower side of the filter element 10, and the interior of the rectangular slot 15 is slidably connected to the upper end of the rectangular block 8. A water diversion pipe 16 is fixedly connected to the center position of the upper side of the connecting pipe 13, and the lower side of the water diversion pipe 16 passes through the upper side of the connecting pipe 13 and is fixedly connected to a blocking head 17. A number of connecting holes 18 are opened through the lower end of the surface of the water diversion pipe 16, and a water supply pipe 19 is fixedly connected to the upper side of the water supply pipe 19. A second electromagnetic valve 20 is fixedly installed at the left end of the water supply pipe 19, and a third electromagnetic valve 21 is fixedly installed at the right end of the water supply pipe 19, which effectively controls the output of purified water and the input of clean water.

[0022] Working principle: When disassembling and replacing the filter element 10, first rotate the pressure plate 6 through the handle 7 to separate the pressure plate 6 from the connecting threaded barrel 5, pull the housing 1 downward, separate the rectangular block 8 from the rectangular slot 15, rotate the rectangular block 8 under the filter element 10 to separate the filter element 10 from the connecting pipe 13, place the rubber waterproof pad 11 and the pressure plate 6 above the replaced filter element 10, and make the connecting pipe 13 pass through the first set of interfaces 12 and the second set of interfaces 14 and be connected with the upper side thread of the new filter element 10. After the filter element 10 is fixed, first engage the rectangular block 8 with the rectangular slot 15, and then rotate the pressure plate 6 to move the pressure plate 6 downward inside the connecting threaded barrel 5 and press the rubber waterproof pad 11 to complete the replacement of the filter element 10. When filtering, the first solenoid valve 3 and the second solenoid valve 2 0 is closed, the water to be filtered enters the housing 1 through the water inlet pipe 4, and after being filtered by the filter element 10, the purified water enters the interior of the filter element 10. The right end of the water pipe 19 is connected to a water pump. Under the action of the water pump, the purified water passes through the connecting hole 18 and the water diversion pipe 16 and is output from the right end of the water diversion pipe 19. When the filter element 10 is blocked, the third electromagnetic valve 21 is closed, the first electromagnetic valve 3 and the second electromagnetic valve 20 are opened, and cleaning water with a certain pressure is input to the left end of the water diversion pipe 19. The cleaning water flows out from the interior of the filter element 10 through the water diversion pipe 16 and the connecting hole 18, flushing away the blocking impurities on the outer surface of the filter element 10, and is discharged through the arc-shaped sewage outlet 9 and the sewage pipe 2, completing the self-cleaning work of the filter element 10, ensuring that the filter element 10 maintains a good filtering effect.
