Description

Technical Field

[0001] This utility model belongs to the technical field of water supply and water treatment devices, specifically a water-saving, differentiated water supply and water treatment device. Background Technology

[0002] Water supply methods include direct water supply and zoned pressure water supply. These methods are determined based on factors such as the nature and height of the building, the condition of the water-using equipment, the water pressure of the distribution network, and fire protection requirements. For example, in multi-story and high-rise buildings, the water pressure of the outdoor distribution network can often only meet the water needs of the lower floors. In this case, the zoned pressure water supply method can make full use of the water pressure of the outdoor distribution network and divide the water supply system into upper and lower zones. The lower zone is directly supplied with water from the outdoor network, while the upper zone is supplied with water through a water pump pressurization system combined with a water tank.

[0003] However, current water supply equipment is unable to differentiate water quality for different water types. In daily life and production activities, different scenarios have vastly different water quality requirements. It is not possible to flexibly treat water according to water demand, which in turn cannot guarantee that the water quality meets the standards. Subsequent water treatment is required, which will cause inconvenience in the process of using the water. Summary of the Invention

[0004] This utility model provides a water-saving, differentiated water supply and treatment device. Through the arrangement of a quartz sand layer, an activated carbon layer, and a precision filter layer, it can remove fine particles, adsorb odors and organic matter, and intercept tiny impurities, thus meeting different water usage requirements. In addition, water can be transported to an ultrafiltration cartridge for further purification, which can meet high water quality requirements.

[0005] This utility model provides a water-saving, differentiated water supply and treatment device, including a filter cylinder. A sealing cover is provided on one side of the filter cylinder. A connecting pipe is fixedly connected to one end of the filter cylinder. A connector is movably connected to one end of the connecting pipe.

It features a folded structure with an outer support frame to prevent deformation and an inner hydrophilic coating to improve water flow efficiency. It is compatible with the inner wall of the deep filter cartridge 7 and can efficiently intercept tiny suspended solids and colloidal particles. One side of the deep filter cartridge 7 has an ultrafiltration cartridge 19. The ultrafiltration cartridge 19 is made of stainless steel and contains a hollow fiber ultrafiltration membrane module. Through the connecting pipe 3, connector 4 and delivery pipe 5, a water delivery path can be formed. The movable connection design of the connector 4 facilitates the disassembly and maintenance of subsequent pipelines. The connection between the delivery pump 6 and the delivery pipe 5 provides power for the delivery of water from the filter cartridge 1 to the deep filter cartridge 7. The quartz sand layer 10, activated carbon layer 11 and precision filter layer 12 on the inner wall of the deep filter cartridge 7 can perform deep water treatment.

[0015] Example 2 A water outlet pipe 13 is fixedly connected to the bottom surface of the deep filter cartridge 7. A drain pipe 15 is fixedly connected to the bottom end of the water outlet pipe 13. One end of the drain pipe 15 passes through the deep filter cartridge 7 and extends into the interior of the deep filter cartridge 7. Two solenoid valves 14 are fixedly connected to the outer surface of the drain pipe 15. A drain valve 20 is fixedly connected to the outer surface of the ultrafiltration cartridge 19. The drain valve 20 is located on one side of the bottom end of the ultrafiltration cartridge 19. A mounting base 21 is fixedly connected to the bottom surface of the filter cartridge 1. Multiple support bases 16 are fixedly connected to the bottom surface of the deep filter cartridge 7. The ultrafiltration cartridge 19... Two mounting base plates 17 are fixedly connected to the bottom surface. The outer surfaces of the two mounting base plates 17 are provided with mounting holes 18, water outlet pipes 13 and drain pipes 15. With the help of two solenoid valves 14 on the surface, the deep filtered water can be directly discharged and transported to the ultrafiltration cartridge 19 for further purification. Through the mounting base 21, multiple support bases 16 on the bottom surface of the deep filter cartridge 7, mounting holes 18 on the bottom surface of the ultrafiltration cartridge 19 and mounting base plates 17, the stability of the device during operation can be ensured, and the displacement or damage of components due to vibration can be avoided.

[0016] The filter cartridge 1 includes a filter cover 101. A threaded cover 104 is threadedly connected to the inner ring of the filter cover 101. A stainless steel coarse filter screen 102 is threadedly connected to the inner ring of the filter cover 101. A limiting ring 103 is fixedly connected to the inner ring of the filter cover 101.

The threaded cover 104 threaded to the inner ring of the filter cover 101 facilitates the disassembly and replacement of the stainless steel coarse filter screen 102 and the threaded cover 104. Water can enter from the water inlet pipe 9 through the sealing cover 2 and then enter the filter cartridge 1, improving the sealing performance of the filter cartridge 1.

[0017] The working principle of this utility model is as follows: First, the water to be treated enters the filter cylinder 1 through the water inlet pipe 9. The water is first filtered through the stainless steel coarse filter screen 102 to intercept larger impurities in the water. After the initial filtration, the water is drawn in by the input end of the delivery pump 6 through the connecting pipe 3 and the delivery pipe 5 on one side of the filter cylinder 1 and delivered to the inside of the deep filter cylinder 7. Water entering the deep filter cartridge 7 undergoes deep purification by passing through the quartz sand layer 10, activated carbon layer 11, and precision filter layer 12 in sequence. The quartz sand layer 10 filters fine particles, the activated carbon layer 11 adsorbs odors and some organic matter in the water, and the precision filter layer 12 intercepts even smaller impurities. The deeply purified water is collected at the bottom of the deep filter cartridge 7 and discharged through the outlet pipe 13 and drain pipe 15. In addition, according to actual water demand, one of the solenoid valves 14 can be opened to directly discharge the deep-filtered water for use in scenarios with low water quality requirements. If higher water quality is required, the other solenoid valve 14 can be opened to transport the water to the ultrafiltration cartridge 19 on one side of the deep filter cartridge 7 for further purification.
