It can also be used in water treatment equipment, environmental protection, desalination of seawater into industrial and domestic water, tap water treatment, water softening, petrochemical industry, terminal filter of petroleum products, filtration of chemical acid and alkali liquids, and recovery and filtration of organic solutions such as alcohol.

[0003] In the prior art, the end cover of the wire-wound screen tube is welded and fixed to one end of the wire-wound tube. Since the wire-wound tube itself has a gap, when the end cover is welded and fixed to the wire-wound tube, the pressure difference resistance of the overall structure is poor. During the water filtering process, the end cover is easily damaged and fails under the pressure of the liquid, thereby affecting the water filtering effect of the wire-wound screen tube. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the wire-wound screen tube in the prior art, such as poor pressure difference resistance, easy damage and failure of the end cover, and influence on the water filtering effect, thereby providing a new wire-wound screen tube, water distributor and ion exchanger.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0009] According to some embodiments of the present invention, the sleeve portion is annular and sleeved on the outer circumference of the wire winding tube, and the inner diameter of the sleeve portion is greater than or equal to the outer diameter of the wire winding tube.

[0010] According to some embodiments of the present invention, the covering portion is an annular plate, and the thickness of the covering portion is equal to the length of the extending section.

[0011] According to some embodiments of the present invention, a diameter of the through hole is greater than or equal to an outer diameter of the base pipe.

[0012] According to some embodiments of the present invention, the thickness of the first end cover is equal to the length of the overhanging section.

[0013] According to some embodiments of the present invention, a plurality of micropores are provided on the peripheral wall of the base tube, a slit is provided on the peripheral wall of the wire winding tube, a flow channel is provided between the base tube and the wire winding tube, and the micropores, the slit, the flow channel and the tube cavity of the base tube form a liquid flow channel.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figure 1As shown, the present invention proposes a novel wire-wrapped screen pipe, comprising: a base pipe 1, a wire-wrapped tube 2, a first end cover 3 and a second end cover 4; the wire-wrapped tube 2 is sleeved on the outside of the base pipe 1, the wire-wrapped tube 2 and the base pipe 1 are coaxially arranged, and one end of the base pipe 1 extends outward from one end surface of the wire-wrapped tube 2 to form an extended section 11; the outer periphery of the first end cover 3 is welded and fixed to the end of the extended section 11; the second end cover 4 is covered on the wire-wrapped tube 2 and sleeved on the extended section 11, and the inner periphery of the second end cover 4 is welded and fixed to the outer periphery of the extended section 11.

[0028] Specifically, the base pipe 1 and the wire wrapping tube 2 are coaxially arranged, the wire wrapping tube 2 is sleeved on the outside of the base pipe 1, one end of the base pipe 1 extends outward from one end surface of the wire wrapping tube 2 to form an extension section 11, the first end cap 3 is covered on the base pipe 1, the outer periphery of the first end cap 3 is welded and fixed to the end of the extension section 11, the second end cap 4 is covered on the wire wrapping tube 2 and sleeved on the end of the extension section 11, and the inner periphery of the second end cap 4 is welded and fixed to the outer periphery of the end of the extension section 11. By fixing the first end cap 3 and the second end cap 4 to one end of the base pipe 1 respectively, during the water filtering process, the operating pressure difference received by the first end cap 3 and the second end cap 4 is transmitted to the base pipe 1. Since the strength of the base pipe 1 is higher than that of the wire wrapping tube 2, the first end cap 3 and the second end cap 4 are directly fixedly connected to the base pipe 1, thereby improving the pressure difference resistance strength of the new wire wrapping screen tube, avoiding damage to the first end cap 3 and the second end cap 4, and ensuring the water filtering effect.

[0029] It can be understood that the extension section 11 provides an installation foundation for fixing the first end cover 3 and the second end cover 4. During the installation process, the first end cover 3 is first covered on the end of the extension section 11, and the outer periphery of the first end cover 3 is welded and fixed to the inner periphery of the extension section 11, and then the second end cover 4 is passed through the extension part and covered on the wire winding tube 2, and the inner periphery of the second end cover 4 is welded and fixed to the outer periphery of the extension section 11. The provision of the extension section 11 facilitates the welding and fixing of the first end cover 3 and the second end cover 4, improves the convenience of installation, and enhances reliability.

[0030] In some embodiments of the present invention, a quarter of the cross section of the second end cover 4 is L-shaped.

[0031] In some embodiments of the present invention, the second end cover 4 includes a covering portion 41 and a sleeve portion 42 that are connected to each other. A through hole is provided in the middle of the covering portion 41. The covering portion 41 is covered on one end of the wire winding tube 2, and the extending section 11 is passed through the through hole. The outer periphery of the extending section 11 is welded and fixed to the wall of the through hole, and the sleeve portion 42 is sleeved on the wire winding tube 2.

[0032] Specifically, a quarter cross-section of the second end cover 4 is L-shaped, the covering portion 41 is plate-shaped, and a through hole is opened in the middle, the sleeve portion 42 is connected to the outer periphery of the covering portion 41, the covering portion 41 is changed to one end of the wire winding tube 2, the extending section 11 is passed through the through hole, and the sleeve portion 42 is sleeved on the wire winding tube 2.

[0033] In some embodiments of the present invention, the sleeve portion 42 is annular and sleeved on the outer circumference of the wire winding tube 2 , and the inner diameter of the sleeve portion 42 is greater than or equal to the outer diameter of the wire winding tube 2 .

[0034] Specifically, the sleeve portion 42 is annular, the inner diameter of the sleeve portion 42 is greater than or equal to the outer diameter of the wire winding tube 2, and the sleeve portion 42 and the wire winding tube 2 are tightly sleeved without gaps to avoid deformation of the wire winding tube 2 caused by welding.

[0036] In some embodiments of the present invention, the thickness of the first end cover 3 is equal to the length of the extending section 11 .

[0037] It is understandable that the cover portion 41 is an annular plate, and the thickness of the cover portion 41 and the thickness of the first end cover 3 are both equal to the length of the extension section 11, so that one side of the cover portion 41 abuts against the end face of the wire winding tube 2 to achieve sealing. The first end cover 3 and the cover portion 41 have the same thickness to ensure the flatness of the end face.

[0038] In some embodiments of the present invention, the diameter of the through hole is greater than or equal to the outer diameter of the base pipe 1 .

[0039] Specifically, the diameter of the through hole is greater than or equal to the diameter of the base pipe 1, so as to ensure that the base pipe 1 can be inserted into the through hole, and the sealing can be ensured after the covering portion 41 is welded to the extending section 11 of the base pipe 1.

[0040] In some embodiments of the present invention, a plurality of micropores 12 are provided on the peripheral wall of the base tube 1, a slit is provided on the peripheral wall of the wire winding tube 2, a flow channel is provided between the base tube 1 and the wire winding tube 2, and the micropores 12, the slit, the flow channel and the lumen of the base tube 1 form a liquid flow channel.

[0041] The invention also discloses a water distributor, which comprises a plurality of novel wire-wound screen tubes, and the plurality of novel wire-wound screen tubes are connected in parallel.

[0042] Specifically, a plurality of new wire-wrapped screen tubes are combined and arranged and then assembled to form a water distributor. The new wire-wrapped screen tubes have high pressure difference resistance and can ensure that the liquid can flow in a preset direction during water distribution, thereby ensuring the distribution effect.

[0043] The invention also discloses an ion exchanger, which is internally provided with a water distributor.

[0044] Specifically, a water distributor is provided in the ion exchanger, and the water distributor is used as a water distribution or water collection device to ensure that during the water distribution or water collection process, the liquid can flow in the flow form required by the design.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
