Technical Field
[0001] The utility model relates to the technical field of EDI modules, in particular to an EDI module concentrated water joint component. Background Art
[0002] ED1 (electrodeionization), or electrodeionization, is a new separation technology that combines ion exchange membranes and ion exchange resins to achieve continuous deep desalination and continuous regeneration of resins under the action of a DC electric field. When the EDI module is actually running, the charged ions in the fresh water migrate to the concentrated water chamber through the migration force of the external electric field. At this time, the conductivity of the concentrated water is relatively high. When it flows out through the concentrated water joint, the internal design of the concentrated water joint of the EDI module currently on the market is not smooth and there are dead corners. During long-term use, the water accumulated in the dead corners cannot be drained away, which will breed bacteria, thereby reducing the quality of the produced water. Therefore, it needs to be improved. Utility Model Content
[0003] Based on this, it is necessary to provide an EDI module concentrated water connector assembly to address the problem that the internal design of the EDI module concentrated water connector on the market is not smooth and has dead corners. During long-term use, the water accumulated in the dead corners cannot be drained, which will breed bacteria and reduce the quality of produced water.
[0004] The utility model provides an EDI module concentrated water connector assembly, comprising:
[0005] A connector body having a first external thread, a first groove, a first inclined surface, and a second external thread, wherein the first external thread is located on an outer wall of one end of the connector body, the first external thread matches with a first internal thread in a concentrated water pipe port on an EDI module, the first groove, the first inclined surface, and the second external thread are all located at the other end of the connector body, and the first groove and the first inclined surface are connected to each other;
[0006] A ferrule is clamped in the first groove, and the outer wall has a second inclined surface, and the second inclined surface is parallel to the first inclined surface;
[0007] A fastening ring, located on the outer wall of the joint body, and the inner wall has a second groove and a second inner thread, and the second inner thread matches the second outer thread;
[0008] When the ferrule is clamped in the first groove, a concentrated water external pipe groove is formed between the ferrule and the joint body, and one end of the ferrule abuts against the fastening ring.
[0009] In one embodiment, one end of the ferrule has a first convex ring. When the EDI module concentrated water external pipe is clamped in the concentrated water external pipe groove and the ferrule is clamped between the EDI module concentrated water external pipe and the connector body, the first convex ring is located in the second groove, and the free end of the first convex ring abuts against the fastening ring.
[0010] In one of the embodiments, the cross-sectional area of the ferrule at one end close to the first protruding ring gradually decreases toward the free end of the ferrule.
[0011] In one of the embodiments, a sealing groove is formed on the inner wall of the joint body, the sealing groove is communicated with the first groove, and a sealing gasket is clamped in the sealing groove.
[0012] In one embodiment, the sealing gasket includes a sealing ring and a second convex ring, and the second convex ring is located on a side of the sealing ring close to the first external thread.
[0013] In one embodiment, a reserved groove is provided on the inner wall of the ferrule, and one end of the reserved groove extends to the free end of the ferrule.
[0014] In one embodiment, the reserved groove has a bending angle, and the bending angle is an acute angle.
[0015] In one of the embodiments, the outer wall of the joint body is fixedly connected to a limiting member.
[0016] When the above-mentioned EDI module concentrated water joint assembly is in use, the end with the first external thread on the joint body is rotated and tightened into the concentrated water pipe mouth on the EDI module, and the ferrule is clamped in the first groove, and then the fastening ring is set on the outer wall of the joint body, and the EDI module concentrated water external pipe is clamped in the concentrated water external pipe groove, and finally the fastening ring is rotated. During this process, under the pushing action of the fastening ring, the ferrule is continuously moved into the first groove, so as to facilitate the docking between the EDI module concentrated water external pipe and the joint body. Since the joints between the joint body, the EDI module concentrated water external pipe and the concentrated water pipe mouth on the EDI module are smooth and there are no dead angles, it is convenient to make the concentrated water flow more smoothly during use, reduce the possibility of bacteria breeding at the joint, and thus improve the water production quality.

[0030] Combine the following Figure 1-Figure 5 The utility model describes an EDI module concentrated water connector assembly.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, an EDI module concentrated water connector assembly includes a connector body 100 , a ferrule 200 and a fastening ring 300 .
[0032] The connector body 100 has a first external thread 110, a first groove 120, a first inclined surface 140 and a second external thread 130. The first external thread 110 is located on the outer wall of one end of the connector body 100. The first external thread 110 matches the first internal thread in the concentrated water pipe outlet on the EDI module. The first groove 120, the first inclined surface 140 and the second external thread 130 are all located at the other end of the connector body 100. The first groove 120 and the first inclined surface 140 are connected to each other.
[0033] The ferrule 200 is clamped in the first groove 120 , and the outer wall of the ferrule 200 has a second inclined surface 210 , and the second inclined surface 210 and the first inclined surface 140 are parallel to each other.
[0034] The fastening ring 300 is located on the outer wall of the joint body 100 , and the inner wall of the fastening ring 300 has a second groove 320 and a second inner thread 310 , and the second inner thread 310 matches the second outer thread 130 .
[0035] When the ferrule 200 is clamped in the first groove 120 , a concentrated water external pipe groove 220 is formed between the ferrule 200 and the joint body 100 , and one end of the ferrule 200 abuts against the fastening ring 300 .
[0036] When the EDI module concentrated water connector assembly is in use, the end with the first external thread 110 on the connector body 100 is rotated and tightened into the concentrated water pipe mouth on the EDI module, and the ferrule 200 is clamped in the first groove 120, and then the fastening ring 300 is sleeved on the outer wall of the connector body 100, and then the EDI module concentrated water external pipe is clamped in the concentrated water external pipe groove 220, and finally the fastening ring 300 is rotated. In this process, under the pushing action of the fastening ring 300, the ferrule 200 is continuously moved into the first groove 120, so as to facilitate the docking between the EDI module concentrated water external pipe and the connector body 100. Since the joints between the connector body 100, the EDI module concentrated water external pipe, and the concentrated water pipe mouth on the EDI module are smooth and there is no dead angle, it is convenient to make the concentrated water flow more smoothly during use, reduce the possibility of bacteria breeding at the joint, and thus improve the water production quality.
[0037] In this embodiment, one end of the ferrule 200 has a first convex ring 230. When the EDI module concentrate water external tube is clamped in the concentrate water external tube groove 220, and the ferrule 200 is clamped between the EDI module concentrate water external tube and the connector body 100, the first convex ring 230 is located in the second groove 320, and the free end of the first convex ring 230 abuts against the fastening ring 300, thereby facilitating the ferrule 200 to clamp the EDI module concentrate water external tube in the connector body 100 under the push of the fastening ring 300.
[0038] It should be supplemented that the cross-sectional area of the end of the ferrule 200 close to the first protruding ring 230 gradually decreases toward the free end of the ferrule 200 .
[0039] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, a sealing groove 150 is formed on the inner wall of the connector body 100 , the sealing groove 150 is communicated with the first groove 120 , and a sealing gasket 400 is clamped in the sealing groove 150 .
[0040] In this embodiment, the sealing gasket 400 includes a sealing ring 410 and a second protruding ring 420 . The second protruding ring 420 is located on a side of the sealing ring 410 close to the first external thread 110 .
[0041] In this embodiment, a reserved groove 240 is provided on the inner wall of the ferrule 200 , one end of the reserved groove 240 extends to the free end of the ferrule 200 , and a bending angle 250 is provided in the reserved groove 240 , and the bending angle 250 is an acute angle.
[0042] When docking the EDI module concentrate water external pipe with the connector body 100, first clamp the sealing ring 410 in the sealing groove 150, then insert the ferrule 200 into the first groove 120, and sleeve the fastening ring 300 on the outer wall of the connector body 100, then clamp the EDI module concentrate water external pipe in the concentrate water external pipe groove 220, and finally rotate the fastening ring 300. During this process, the ferrule 200 is continuously moved into the first groove 120 under the pushing action of the fastening ring 300. On the one hand, by clamping the sealing gasket 400 in the sealing groove 150, the sealing performance of the joint between the connector body 100 and the EDI module concentrate water external pipe can be effectively improved. On the other hand, during the process of the ferrule 200 moving into the first groove 120, the outer wall of the EDI module concentrate water external pipe is engaged with the reserved groove 240 under the squeezing action of the ferrule 200, thereby improving the stability of the EDI module concentrate water external pipe.
[0043] It should be supplemented that the outer wall of the joint body 100 is fixedly connected to the limiting member 160 , so as to conveniently limit the moving range of the fastening ring 300 .
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
