Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a water purification device containing a molecular sieve. Background Art

[0002] In recent years, with the rapid development of social economy and the improvement of people's living standards, the discharge of water pollutants contained in industrial sewage and domestic sewage has increased year by year, resulting in a considerable shortage of water resources in my country. Most of the sewage that has not been treated by sewage treatment facilities is directly discharged into the fields and rivers nearby, which not only causes various natural water bodies to be polluted to varying degrees, wastes precious water resources, but also directly or indirectly threatens human health and even life. Therefore, the prevention and control of pollution of natural water bodies has become a major problem that needs to be solved urgently.

[0003] Heavy metal pollutants are a common water pollution problem and the most difficult type of water pollution problem to deal with. At present, the most common method of removing heavy metals in water purifiers is to use RO reverse osmosis membranes. RO reverse osmosis membranes have very small pores and can only pass water molecules but not large molecules such as heavy metal ions, thereby achieving the purpose of removing heavy metal pollutants in water. However, when RO reverse osmosis membranes remove heavy metals, trace elements in the water that are beneficial to the human body are also removed simultaneously. Therefore, it is urgent to develop a water purification device that can both efficiently remove heavy metals in water and retain trace elements. Summary of the invention

[0004] The technical problem solved by the present invention is to overcome the existing defects and provide a water purification device containing molecular sieves. The device is simple and efficient and can fully utilize the adsorption characteristics of molecular sieves to remove heavy metals in water while retaining beneficial trace elements in the water.

[0005] The water purification device containing molecular sieves comprises a detachable upper cover, a shell and a water purification unit placed in the shell, the shell is provided with a cavity inside, the upper cover is provided with a water inlet hole and a drain pipe, the drain pipe is a hollow structure, the top of the drain pipe is a through hole connected to the outside, the bottom is a blind hole, the lower end of the upper cover of the drain pipe is connected to the water purification unit, the wall of the drain pipe connected to the water purification unit is provided with a plurality of hole structures, the filter material is in sheet shape when the water purification unit is unfolded, one side of the adsorption area of ​​the filter material is connected to the drain pipe, and the other side is connected to the filtration area, the filter material is wound around the drain pipe as the center to form a cylindrical structure with upper and lower sealing and side water inlet; the adsorption area contains molecular sieves. The water purification unit is curled into a cylindrical shape to form a spirally wound flow channel, further improving the adsorption efficiency.

[0006] Furthermore, the upper cover and the shell are sealed by threads.

[0007] Furthermore, the adsorption area and the filtration area are integrally formed during processing or spliced ​​together by bonding.

[0008] Furthermore, the filter material of the adsorption zone is a non-woven fabric, and the non-woven fabric is loaded with a molecular sieve or a mixture of a molecular sieve and activated carbon. Since the active groups on the surface of the molecular sieve can form ionic bonds or covalent bonds with heavy metal ions in water, the surface of the molecular sieve can adsorb heavy metal ions to achieve the purpose of removing heavy metals. Activated carbon has the dual characteristics of physical adsorption and chemical adsorption, and can adsorb various substances in water to achieve the purposes of filtering, deodorizing, decolorizing, removing chemical pollution and volatile organic compounds, etc., which can save costs.

[0009] Furthermore, the molecular sieve is a natural molecular sieve or a synthetic molecular sieve.

[0010] Furthermore, the synthetic molecular sieve is one or a combination of silicon-aluminum-based, phosphate-based, and titanium-silicon-based molecular sieves.

[0011] Furthermore, the filtration area is made of membrane material, which can effectively remove pollutants such as particulate matter, sediment, bacteria, viruses, colloids, macromolecular organic matter, etc. in the water.

[0012] Beneficial effects of the utility model:

[0013] Through this device, the active groups on the surface of the molecular sieve can form ionic bonds or covalent bonds with heavy metal ions in the water, adsorbing heavy metal ions on the surface of the molecular sieve to achieve the purpose of removing heavy metals. At the same time, since the molecular sieve has no adsorption capacity for mineral ions such as calcium, magnesium, and zinc, the beneficial mineral ions in the water can be retained.

[0014] The water purification unit of the water purification device includes a filtration area and an adsorption area, which can efficiently remove pollutants such as particulate matter, sediment, bacteria, viruses, colloids, macromolecular organic matter, etc. in the water body, and can also efficiently remove heavy metals. The device is simple and has a good water purification effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1

[0021] Reference Figure 1-3 A water purification device containing a molecular sieve includes an upper cover 3, a shell 5 and a water purification unit 4. The upper cover 3 and the shell 5 are connected by a threaded seal. A cavity is provided inside the shell 5. The upper cover 3 is provided with a water inlet hole 2 and a drain pipe 1. The drain pipe 1 is a hollow structure. The top of the drain pipe 1 is a through hole connected to the outside world, and the bottom is a blind hole. The lower end of the upper cover of the drain pipe 1 is connected to the water purification unit 4. A plurality of hole structures 8 are opened on the wall of the drain pipe 1 connected to the water purification unit 4. When the water purification unit 4 is unfolded, the filter material is in a sheet shape. Adhesive 9 is applied on both sides of the filter material. One side of the adsorption area 6 of the filter material is connected to the drain pipe 1, and the other side is connected to the filtration area 7. The filter material is wound around the drain pipe 1 as the center to form a cylindrical structure that is sealed from top to bottom and water is fed from the side. The adsorption area 6 and the filtration area 7 can be formed in one piece during processing, or they can be spliced ​​and formed by bonding. The filter material of the adsorption zone 6 is a non-woven fabric, which is loaded with a molecular sieve or a mixture of a molecular sieve and activated carbon, wherein the ratio of the molecular sieve to the activated carbon is 2: 1. The filter material of the filtration zone 7 is a membrane material, which is a hollow fiber external pressure structure. Specific embodiment:

[0023] 1. Water purification process:

[0024] When the tap is turned on, raw water enters the water purification device from the water inlet 2 and is filtered through the water purification unit 4. The raw water first passes through the membrane material of the filtration area 7 to remove pollutants such as particles, sediment, bacteria, viruses, colloids, and macromolecular organic matter in the water, and then passes through the filter material loaded with molecular sieves in the adsorption area 6 to fully adsorb and remove heavy metals, and then flows out of the water purification device through the drain pipe 1.

[0025] 2. Flushing process:

[0026] When there are too many pollutants in the device, resulting in a small water output, reverse flushing can be performed. The specific method is: open the clean water tap, flush the filter material loaded with molecular sieves in the adsorption area 6 with clean water, and then flush the membrane material in the filtration area 7 to remove the pollutants attached to the filter material. The dirty water after flushing is discharged from the device through the water inlet 2.

[0027] This water purification device can effectively filter pollutants such as particulate matter, sediment, colloid, macromolecular organic matter, etc. in the water body; and can retain beneficial trace elements in the water while removing harmful heavy metals in the water. The device is simple and efficient.
