[0025] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0026] like Figures 1 to 5 As shown, a medium-to-large water purification device includes a mounting frame 1, a water tank 2 and a water purification mechanism, the water tank 2 is fixedly arranged on the top of the mounting frame 1, and the water purification mechanism includes a coarse filtration component, a disinfection component and a semipermeable membrane component; the coarse filtration component includes a water pump 3, a filter barrel 31 and a connecting pipe 33, one end of the connecting pipe 33 is connected to the water tank 2, and the other end is connected to the filter barrel 31, a plurality of filter screens 32 are arranged inside the filter barrel 31, the water pump 3 is arranged on the side wall of the filter barrel 31, and a conduit 35 is arranged on the filter barrel 31, the conduit 35 is connected to the disinfection component, and the disinfection component is connected to the semipermeable membrane component.

[0027] There are three filter screens 32, and the apertures of the filter screens 32 decrease successively along the end away from the connecting pipe. The apertures of the three filter screens 32 in the filter barrel 31 decrease successively. After the raw water enters the filter barrel 31, it first passes through the filter screen 32 with the largest aperture to intercept larger suspended matter, mud and sand and other particles in the water; as the water continues to flow forward, it passes through the filter screens 32 with gradually decreasing apertures to further remove smaller particles of impurities, such as fine gravel, colloids, etc., to achieve gradual filtration from large particles to tiny particles; the multi-stage filter screen 32 with decreasing aperture design forms a well-defined filtration system, which can more efficiently remove impurities of different particle sizes. The large-aperture filter screen 32 first intercepts large particles, reduces the burden on the subsequent filter screens 32, and extends the overall filtration life; the small-aperture filter screen 32 further performs fine filtration to ensure a coarse filtration effect.

[0028] The disinfection assembly includes a disinfection box 4 and an activated carbon filter layer. The disinfection box 4 is fixedly set on the mounting frame 1. One end of the conduit 35 is connected to the top of the filter barrel 31, and the other end is connected to the bottom of the disinfection box 4. The conduit 35 is connected to one side of the filter mesh 32 with the smallest pore size, and the activated carbon filter layer is set in the middle position inside the disinfection box 4.

[0029] The coarsely filtered water flows from the top of the filter barrel 31 through the conduit 35 into the bottom of the disinfection tank 4, where it flows upward through the activated carbon filter layer. The activated carbon has a rich pore structure and strong adsorption capacity. As the water passes through, it absorbs organic matter, pigments, odors, and some residual impurities. At the same time, the chemicals on the activated carbon surface have a certain inhibitory effect on microorganisms in the water, reducing the number of bacteria and viruses in the water, completing the initial disinfection and further purification.

[0030] The top of the disinfection box 4 is connected to a circulation pipe 41, and the semipermeable membrane assembly includes a semipermeable membrane barrel 5 and a columnar semipermeable membrane 51. The semipermeable membrane barrel 5 is fixedly set on the mounting frame 1, and an annular cover plate 52 is set on the top of the semipermeable membrane barrel 5. The columnar semipermeable membrane 51 is set inside the semipermeable membrane barrel 5 and fixedly connected to the annular cover plate 52. The circulation pipe 41 is used to be connected to the semipermeable membrane barrel 5.

[0031] The annular cover plate 52 has a liquid inlet 521 on one sidewall and a liquid outlet 522 on the other sidewall. The liquid inlet 521 communicates with the outside of the columnar semipermeable membrane 51, while the liquid outlet 522 communicates with the inside of the columnar semipermeable membrane 51. One end of the flow tube 41 communicates with the top of the disinfection box 4, and the other end communicates with the liquid inlet 521.

[0032] After disinfection, water flows through the flow tube 41 through the liquid inlet 521 and into the outer side of the cylindrical semipermeable membrane 51. Under pressure, water molecules are able to pass through the tiny pores of the semipermeable membrane and into the interior of the cylindrical semipermeable membrane 51. However, bacteria, viruses, heavy metal ions, and large organic molecules in the water, which are larger than the pores of the semipermeable membrane, cannot pass through the membrane and are trapped on the outer side. The purified water flows out through the liquid outlet 522, effectively removing microscopic contaminants from the water.

[0033] The semipermeable membrane assembly utilizes its unique screening principle to precisely intercept tiny harmful substances in water. Compared to traditional filtration methods, it achieves a nearly 100% removal rate for bacteria and viruses and over 99% for heavy metal ions, significantly improving water purification. The structural design of the columnar semipermeable membrane 51 and the annular cover plate 52 increases the membrane's filtration area and improves filtration efficiency. This structure also facilitates installation and replacement of the membrane, reducing maintenance. Through the deep purification provided by the semipermeable membrane assembly, the purified water meets or even exceeds national drinking water standards, meeting high-end water needs.

[0034] A control box 11 is mounted on the mounting frame 1. This box houses built-in control circuitry and sensors, which monitor the operating status of the water pump 3, the water pressure in each component, the water flow rate, and the quality parameters of the purified water (such as turbidity, pH, and microbial content) in real time. Operators can view these parameters on the display screen of the control box 11 and, as needed, start and stop the water pump 3 and adjust the water flow rate. If equipment malfunctions or water quality is abnormal, the control box 11 will issue an alarm and automatically implement appropriate protective measures, such as stopping the water pump 3 to prevent damage or the outflow of substandard water.

[0035] The mounting frame 1 is equipped with several reinforcing ribs 12. Made from high-strength metal, these ribs are secured by welding or bolting to key locations on the frame, such as the junctions between the columns and beams, the water tank 2, and the supporting areas of various components. During operation, these ribs absorb the stresses borne by the mounting frame 1 from gravity, water flow, and vibration, enhancing its overall rigidity and stability and preventing deformation, bending, or collapse.

[0036] The connecting pipe is equipped with a control valve 34. This valve is manually or electrically adjustable, and its opening can be adjusted by rotating a handle or an electric control device. Increasing the valve opening increases the flow of raw water into the filter tank 31; decreasing the valve opening decreases the flow. Operators can flexibly adjust the opening of the control valve 34 based on the raw water quality, equipment processing capacity, and water demand to control the flow of raw water into the water purification device.

[0037] The present invention operates as follows: Water to be purified is poured into a water tank 2. Under the influence of gravity, the water in the tank 2 flows through a connecting pipe 33 into the filter barrel 31 of the coarse filtration assembly. At this point, a water pump 3 is activated, pressurizing the water in the filter barrel 31 and circulating it through the three internal filters 32. Starting with the larger pore size, the filters 32 sequentially intercept larger impurities and particles. As the pore size of the filters 32 decreases, they further filter out smaller impurities, completing the initial coarse filtration process. The coarsely filtered water then flows through a conduit 35 on the filter barrel 31 into the disinfection chamber 4 of the disinfection assembly. Because the conduit 35 is connected to the side of the filter 32 with the smallest pore size, the water entering the disinfection chamber 4 has undergone a relatively thorough coarse filtration. As the water rises within the disinfection chamber 4, it passes through an activated carbon filter layer located in the center of the chamber. This layer absorbs odors, some organic matter, and residual microorganisms. Microorganisms are also suppressed to a certain extent during this process, achieving a preliminary purification of the water quality. After being purified by the activated carbon filter layer, the water flows out of the circulation pipe 41 at the top of the disinfection box 4 and enters the semipermeable membrane barrel 5 of the semipermeable membrane assembly through the connecting pipe. Water flows from the outer side of the cylindrical semipermeable membrane 51 through the liquid inlet 521 on one side of the annular cover plate 52. Under pressure, water molecules penetrate the cylindrical semipermeable membrane 51 and enter the interior. Impurities such as bacteria, viruses, large organic molecules, and inorganic salts in the water are intercepted by the semipermeable membrane, achieving further purification. The purified water then flows out of the liquid outlet 522 on the other side of the annular cover plate 52. The purified water flowing out of the semipermeable membrane assembly can be collected and used directly or piped to a designated location as needed. During this process, the control box 11 on the mounting frame 1 monitors and controls the operation of the entire water purification system, including starting and stopping the water pump 3 and monitoring the operating status of various components. The control valve 34 on the connecting pipe adjusts the water flow rate and volume. The reinforcing ribs 12 on the mounting frame 1 ensure the stability of the entire system during operation.
