Description

Technical Field

[0001] This utility model relates to the field of multi-stage pure water treatment technology, and in particular to a multi-stage pure water treatment device. Background Technology

[0002] Multi-stage pure water treatment equipment is an advanced water treatment system that effectively removes harmful substances and impurities from water through multi-stage filtration technology, providing high-purity drinking water and industrial water. Its core component is the reverse osmosis membrane, which effectively intercepts harmful substances such as microorganisms, heavy metals, and organic matter in the water, as well as removing particles, odors, and color. Through the synergistic effect of the multi-stage filtration system, pure water equipment can achieve highly efficient water purification, producing sterile, transparent, and refreshing high-quality drinking water. Furthermore, the filtration accuracy of industrial pure water equipment is also an important indicator for evaluating its quality; the design and material selection of the filter element have a significant impact on the filtration accuracy. Common filter element materials include ceramics, cellulose, and precision filter membranes, with different materials corresponding to different filtration accuracies.

[0003] Existing multi-stage pure water treatment equipment requires a complete shutdown when replacing filter cartridges, and the replacement time for multiple filter cartridges is relatively long. If only a single filter cartridge is replaced, the entire equipment still needs to be shut down for maintenance and replacement, resulting in low work efficiency. Therefore, we have proposed a multi-stage pure water treatment equipment. Utility Model Content

[0027] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] refer to Figure 1-4 A multi-stage pure water treatment device includes a multi-stage filtration device mounting plate 3.

The aromatic polyamide composite membrane filter element 14 is respectively fixedly installed on the inner side of the first filtration pipe 11, the second filtration pipe 12, and the third filtration pipe 13. The aromatic polyamide composite membrane filter element 14 can intercept impurities in water molecules and only allow water molecules to pass through, resulting in high-purity pure water as the effluent.

[0031] In this embodiment, a diversion pipe 8 is fixedly installed on the inner side of the water inlet pipe 5. A first connecting flange 9 and fixing bolts are provided at the connection between the water inlet pipe 5 and the diversion pipe 8. A pure water filter disassembly and diversion guide assembly 2 is provided on the pure water multi-stage filtration treatment device 1 and the diversion pipe 8.

[0032] In this embodiment, the pure water multi-stage filtration treatment device 1 also includes a motor 16, a drive shaft 17, a transmission gear 18, a rack 19, and a slide rod 20. The motor 16 is fixedly installed on one side of the first protective cover 4, the drive shaft 17 is fixedly installed on the output end of the motor 16, the transmission gear 18 is fixedly installed on the outside of the drive shaft 17, the slide rod 20 is slidably installed on the inside of the water inlet valve body 6, and the rack 19 is fixedly installed on the top of the slide rod 20.

[0033] In this embodiment, a valve core 21 is fixedly installed at the bottom of the slide bar 20, and a valve seat 22 is fixedly installed on the inner side of the water inlet valve body 6.

[0034] In this embodiment, the pure water filter disassembly and diversion assembly 2 includes a fixing plate 23, a drive shaft 24, a first bevel gear 25, a valve stem 26, and a butterfly valve body 27.

Therefore, there is no need to repeat it in this utility model patent document.

[0039] Specifically, multiple guide pipes 7 and inlet valve bodies 6 are installed above the multi-stage filtration equipment mounting plate 3. The first filter pipe 11, the second filter pipe 12, and the third filter pipe 13 are installed on opposite sides of the guide pipes 7 and the inlet valve bodies 6 via the second connecting flange 15 and bolts. Aromatic polyamide composite membrane filter elements 14 are installed inside the first filter pipe 11, the second filter pipe 12, and the third filter pipe 13. Since pure water needs to undergo multi-stage filtration, the treatment equipment has multiple sets of multi-stage filtration equipment mounting plates 3. The filter elements installed on each multi-stage filtration equipment mounting plate 3 are different, but each filter element has multiple sets. When it is necessary to replace the aromatic polyamide composite membrane filter element 14, the motor 16 can be controlled to drive the drive shaft 17 and the transmission gear 1. When the drive shaft 17 rotates, the transmission gear 18 and rack 19 mesh, which can drive the slide rod 20 and valve core 21 to move downward, so that the valve core 21 blocks the valve seat 22, preventing water from entering the inlet valve body 6. After the drive shaft 17 rotates, it can drive the transmission shaft 24 to rotate through the first bevel gear 25. After the transmission shaft 24 rotates, it can drive the valve stem 26 and butterfly valve body 27 to rotate through the second bevel gear 28. After the butterfly valve body 27 rotates, it can be opened, allowing the water in the inlet pipe 5 to flow through the diversion pipe 8 into the lower guide pipe 7 and another set of inlet pipes 5. At this time, the filter element can be replaced without stopping the equipment, which can greatly improve the working efficiency. The lowermost guide pipe 7 can be connected to a pipe to transmit pure water to another set of pure water treatment equipment.

[0040] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
