Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a highly efficient and sealed ultrafiltration pure water equipment. Background Art

[0002] Ultrafiltration is a membrane separation technology between microfiltration and nanofiltration, with an average pore size of 3-100nm. It purifies, separates, and concentrates solutions. Its retention mechanism primarily involves membrane sieving and electrostatic forces. Driven by a pressure differential across the ultrafiltration membrane, the filtration medium allows only low-molecular-weight solutes and water to pass through, achieving purification, separation, and concentration. Ultrafiltration membrane technology has a wide range of applications. The earliest ultrafiltration membranes used were natural membranes derived from animal organs. Initially, ultrafiltration remained an experimental endeavor and was not developed until the 1970s, when ultrafiltration technology entered a period of rapid industrial development. Pure water is H2O free of impurities.

[0003] At present, the Chinese utility model patent application with publication number CN213853911U proposes a pure water ultrafiltration membrane, which relates to the technical field of filtration equipment, including an outer packaging, a mounting groove is provided on the front of the outer packaging, the mounting groove is penetrated by the outer packaging, a filter membrane is provided in the mounting groove, the filter membrane is fixed to the surface inside the outer packaging, and mounting covers are provided at both ends of the outer packaging, the mounting covers are abutted against the two ends of the outer packaging, and a ferrule is provided on one side of the mounting covers at both ends, and the ferrule is threadedly fixed to one side of the mounting cover, and a water production pipe is provided in the mounting groove, and the two ends of the water production pipe respectively penetrate the groove on one side of the ferrule, and the water production pipe is bolted to the ferrule. The mounting cover and the water production pipe are used, and the water production pipe is penetrated into the groove on one side of the ferrule. The liquid enters from the water inlet on one side of the mounting cover on both sides at the same time. By installing multiple water production pipes and fixing the equipment, the filtered liquid flows out from both ends of the water production pipe at the same time, thereby increasing the processing capacity of the equipment, effectively improving the processing efficiency of the equipment, and reducing the waiting time for water output.

[0004] However, the sealing structure of the connection seal of the filtration equipment is generally provided with a sealing ring to ensure the sealing performance. However, due to the tight fit of the sealing connection, the sealing ring often cannot withstand excessive pressure and is distorted or even damaged, affecting the sealing performance and causing liquid leakage.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] Based on this, the technical problem in the related art that the sealing ring at the sealing connection is easily twisted and deformed or even damaged due to excessive pressure can be improved. The embodiment of the present application provides the following solution.

[0031] Please also refer to Figures 1 to 5 The embodiment of the present application provides a highly efficient sealed ultrafiltration pure water device, comprising an outer package 10, a flange assembly 20, a sealing assembly 30 and a filter assembly 40.

[0032] The flange assembly 20 includes a first flange 21, a second flange 22 and bolts 23. The first flange 21 is provided on the side walls at both ends of the outer packaging 10, and the second flange 22 is connected to the first flange 21 by bolts 23.

[0033] The sealing assembly 30 includes an X-shaped sealing ring 31, a first support portion 32, and a second support portion 33. The first support portion 32 is mounted on the first flange 21 by providing a sealing groove 211. The second support portion 33 is disposed on the second flange 22. The X-shaped sealing ring 31 is disposed in the sealing groove 211. The first support portion 32 and the second support portion 33 respectively abut against the recessed portions on both sides of the X-shaped sealing ring 31.

[0034] The filter assembly 40 is used to filter liquid.

[0035] From the above, it can be seen that the first support portion 32 and the second support portion 33 can abut and support the two ends of the X-shaped sealing ring 31, thereby reducing the probability of excessive twisting and deformation of the X-shaped sealing ring 31 after being squeezed, reducing the probability of damage and other problems that may affect the sealing performance of the X-shaped sealing ring 31, and then reducing the probability of liquid leakage; the abutment of the first support portion 32 and the second support portion 33 on the two ends of the X-shaped sealing ring 31 can also release the stress of the sealing ring toward the radial direction of the pipeline, thereby making the abutment of the X-shaped sealing ring 31 with the inner wall of the sealing element and the sealing shaft tighter, further enhancing the sealing performance; making it difficult for the sealing ring to deform or break.

[0036] Optionally, in some embodiments, see Figures 1 to 3 The X-shaped sealing ring 31 has a first groove 311 and a second groove 312 arranged opposite to each other. The X-shaped sealing ring 31 has a first state after installation. In the first state, the first support portion 32 and the second support portion 33 respectively abut against the bottom of the first groove 311 and the bottom of the second groove 312, and the side walls of the X-shaped sealing ring 31 are respectively in contact with the first flange 21 and the sealing groove 211.

[0037] In this arrangement, the first support portion 32 abuts against the bottom of the first groove 311, and the second support portion 33 abuts against the bottom of the second groove 312. The stress of the X-shaped sealing ring 31 is released radially toward the pipeline. Under the elastic action, the two sides of the X-shaped sealing ring 31 clamp and seal the first support portion 32 and the second support portion 3333 respectively, and contact the first flange 21 and the sealing groove 211 respectively. The effective contact area between the first support portion 32 and the second support portion 33 and the X-shaped sealing ring 31 can be made large enough, thereby ensuring the supporting effect of the first support portion 32 and the second support portion 33 and the X-shaped sealing ring 31, and enabling the X-shaped sealing ring 3131 to contact the first flange 21 and the second flange 22 respectively under relatively small deformation to form a seal, thereby further improving the sealing performance.

[0038] Optionally, in some embodiments, see Figures 4 and 5 The X-shaped sealing ring 31 has a second state when it is not installed. In the second state, the maximum groove depth of the first groove 311 is less than the length of the first support portion 32, the maximum groove depth of the second groove 312 is less than the length of the second support portion 33, and the groove depth of the sealing groove 211 is greater than the thickness of the X-shaped sealing ring 31.

[0039] In this way, when the second flange 22 is docked with the first flange 21, the two sides of the X-shaped sealing ring 31 first contact the first supporting portion 32 and the second supporting portion 33. At this time, there is a gap between one side of the X-shaped sealing ring 31 and the first flange 21, and there is a gap between the other side and the bottom of the sealing groove 211; the first supporting portion 32 abuts against the bottom of the first groove 311, and the second supporting portion 33 abuts against the bottom of the second groove 312, forming a seal. The two sides of the X-shaped sealing ring 31 are elastically pressed against the first support portion 32 and the second support portion 33 respectively. The support portion 32 and the second support portion 33 are clamped and sealed. During the clamping and sealing process of the X-shaped sealing ring 31, the side walls on both sides of the X-shaped sealing ring 31 are in contact with the first flange 21 and the sealing groove 211 respectively, further enhancing the sealing performance. Therefore, the groove depth of the sealing groove 211 is greater than the thickness of the X-shaped sealing ring 31, which facilitates the two sides of the X-shaped sealing ring 31 to clamp and seal the first support portion 32 and the second support portion 33 respectively under the action of elasticity, thereby enhancing the sealing and supporting effects of the sealing assembly 30.

[0040] Optionally, in some embodiments, see Figure 3-Figure 5 The first supporting portion 32 and the second supporting portion 33 are both rib structures.

[0041] In this arrangement, the first support portion 32 and the second support portion 33 of the rib structure directly abut against the bottom of the first groove 311 and the second groove 312, thereby enhancing the supporting effect of the X-shaped sealing ring 31. At the same time, the rib structure can also support the X-shaped sealing ring 31 along the radial direction of the sealing axis, further ensuring the structural stability of the X-shaped sealing ring 31.

[0042] Optionally, in some embodiments, see Figures 1 to 2 The flange assembly 20 further includes a nut 24 , which is rotatably connected to the bolt 23 and abuts against the side wall of the first flange 21 away from the second flange 22 .

[0043] Such arrangement allows the nut 24 to abut against the first flange 21 during the process of being rotated and installed on the bolt 23 , further increasing the firmness of the connection between the first flange 21 and the second flange 22 .

[0044] Optionally, in some embodiments, see Figures 1 to 2 The filter assembly 40 includes a filter membrane 41 and a water inlet pipe 42. The outer packaging 10 is provided with a mounting groove 11. The filter membrane 41 is located in the mounting groove 11. The filter membrane 41 is fixedly installed on the water inlet pipe 42. Both ends of the water inlet pipe 42 are passed through the second flange 22. A plurality of water outlet holes 421 are provided on the water inlet pipe 42, and a plurality of water outlets 221 are provided on the second flange 22.

[0045] With such an arrangement, when the equipment needs to increase the water inlet, the water output of the equipment cannot reach the required flow rate. By passing the water inlet pipe 42 through the second flange 22, the liquid enters the filter membrane 41 through the water outlet hole 421 from both sides of the water inlet pipe 42 for filtration, and the filtered liquid flows out from the water outlet 221 at both ends of the outer packaging 10 at the same time, thereby increasing the processing capacity of the equipment, effectively improving the processing efficiency of the equipment, and reducing the waiting time for water outlet.

[0046] Optionally, in some embodiments, see Figures 1 to 2 A limiting rod 422 is provided on the water inlet pipe 42, and a limiting groove 411 is provided on the filter membrane 41 to match the limiting rod 422. The protrusion of the side wall of the limiting rod 422 abuts against the concave part of the inner wall of the limiting groove 411.

[0047] With this arrangement, the limiting rod 422 is engaged in the limiting groove 411 , so that the filter membrane 41 is unlikely to deviate or become loose during use.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
