Description

Technical Field

[0001] This utility model relates to the field of water circulation device technology, specifically a water circulation device with a scale filtration structure. Background Technology

[0002] A circulating pump is a pump used in a device to transport circulating liquids for reaction, absorption, separation, and absorption liquid regeneration. It has a relatively low head, used only to overcome the pressure drop in the circulating system. Low-head pumps can be used. The term "circulating pump" refers to the pump's function, while "centrifugal pump" refers to its structure; these are completely different concepts. The working principle of a circulating pump is to circulate water; for example, hot water in a plumbing system is circulated by a circulating pump, and the circulating pump is a crucial component inside the return water circulator.

[0003] Currently, commercially available water recirculators require pipe connections at both ends for use. In actual use, once the pipe connections are complete, the circulating pump within the recirculator applies power to the liquid inside the pipes. Typically, the water flows directly through the pump. Due to the high temperature of the water inside the recirculator, scale gradually accumulates in the pipes, leading to reduced flow rate or blockages. When a filter membrane is installed on the inlet side of the recirculator, its placement inside makes replacement inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a water recirculator with a scale filtration structure to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water circulator with a scale filtration structure includes a circulator body and an outlet pipe fixedly connected to the outer wall of the circulator body. A filter box is fixedly connected to the outer wall of the circulator body away from the outlet pipe. A filter groove is formed inside the filter box. A groove is formed inside the filter box on one side of the filter groove. A fixing rod is fixedly connected inside the groove. A positioning rod is slidably connected to the outer wall of the fixing rod. A pressure plate is fixedly connected to the outer wall of the positioning rod. A rotating rod is provided inside the groove. A squeezing rod is fixedly connected to the outer wall of the rotating rod. One end of the positioning rod passes through the filter groove and is slidably connected to the filter box. A filter frame is slidably connected inside the filter groove. A positioning groove is formed on the outer wall of the filter frame and one end of the positioning rod is slidably connected to the positioning groove.

[0007] Furthermore, a spring is provided between the positioning rod and the groove, one end of the rotating rod passes through the outer wall of the filter box and the rotating rod is rotatably connected to the filter box. The addition of the fixing rod restricts the movement trajectory of the positioning rod.

[0008] Furthermore, the two ends of the spring are fixedly connected to the inside of the groove and the outer wall of the positioning rod, respectively. The cross-sectional shape of the pressure plate is set to an arc shape. The addition of the spring allows the positioning rod to return to its initial position.

[0009] Furthermore, a mounting plate is slidably connected inside the filter frame, and a nanofiltration membrane is fixedly connected to the outer wall of the mounting plate. The addition of the squeezing rod allows the rotating rod to drive the pressure plate to move.

[0010] Furthermore, an installation groove is provided on one side of the outer wall of the mounting plate, and a threaded rod passes through the inside of the filter frame. The threaded rod is connected to the filter frame by threads. The addition of the positioning groove makes it easy to fix the position of the filter frame.

[0011] Furthermore, one end of the threaded rod is slidably connected to the mounting groove, and the addition of the threaded rod makes it easier to fix the position of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The water recirculator with a scale filtration structure described in this utility model can filter subsequent water in a timely manner. By setting a squeezing rod on the outer wall of the rotating rod, a fixing rod inside the groove, a positioning rod on the outer wall of the fixing rod, a pressure plate on the outer wall of the positioning rod, a spring between the positioning rod and the groove, and a positioning groove on the outer wall of the filter frame, one end of the positioning rod can move inside the positioning groove. In this utility model, the nanofiltration membrane can filter the water in a timely manner. At the same time, when the nanofiltration membrane in this device needs to be replaced, rotating the rotating rod allows one end of the positioning rod to enter and separate from the positioning groove, thereby ensuring that the filtration of water by the nanofiltration membrane inside the filter frame is not affected.

[0014] 2. The water recirculator with scale filtration structure described in this utility model allows for easy disassembly of the nanofiltration membrane inside the filter frame. By setting an installation plate inside the filter frame, setting an installation groove on the outer wall of the installation plate, and setting a threaded rod on the outer wall of the filter frame, one end of the threaded rod can move in and out of the installation groove. In this utility model, when it is necessary to disassemble the nanofiltration membrane of the filter frame, the threaded rod is rotated to facilitate the replacement of the nanofiltration membrane.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a water recirculator with a scale filtration structure, the technical solution of which is as follows:

[0022] A water circulator with a scale filtration structure includes a circulator body 1 and an outlet pipe 2 fixedly connected to the outer wall of the circulator body 1. A filter box 3 is fixedly connected to the outer wall of the circulator body 1 away from the outlet pipe 2. A filter groove 4 is opened inside the filter box 3. A groove 5 is opened inside the filter box 3 on one side of the filter groove 4. A fixing rod 6 is fixedly connected inside the groove 5. A positioning rod 7 is slidably connected to the outer wall of the fixing rod 6. A pressure plate 8 is fixedly connected to the outer wall of the positioning rod 7. A rotating rod 9 is provided inside the groove 5. A squeezing rod 10 is fixedly connected to the outer wall of the rotating rod 9. One end of the positioning rod 7 passes through the interior of the filter groove 4 and is slidably connected to the filter box 3. A filter frame 11 is slidably connected inside the filter groove 4. A positioning groove 12 is opened on the outer wall of the filter frame 11 and one end of the positioning rod 7 is slidably connected to the positioning groove 12.

[0023] In a preferred embodiment, a spring 13 is provided between the positioning rod 7 and the groove 5. One end of the rotating rod 9 passes through the outer wall of the filter box 3 and the rotating rod 9 is rotatably connected to the filter box 3. When the positioning rod 7 moves, the positioning rod 7 will move on the outer wall of the fixed rod 6, so that the positioning rod 7 can compress the spring 13.

[0024] In a preferred embodiment, the two ends of the spring 13 are fixedly connected to the inside of the groove 5 and the outer wall of the positioning rod 7, respectively. The cross-sectional shape of the pressure plate 8 is set to an arc shape. When the pressure plate 8 moves, the pressure plate 8 will move inside the groove 5, and at the same time, the pressure plate 8 will drive the positioning rod 7 to move.

[0025] In a preferred embodiment, a mounting plate 14 is slidably connected inside the filter frame 11, and a nanofiltration membrane 15 is fixedly connected to the outer wall of the mounting plate 14. When the rotating rod 9 moves, the rotating rod 9 will drive the squeezing rod 10 to move, so that the squeezing rod 10 can drive the pressure plate 8 to move.

[0026] The working principle of this utility model is as follows: When the water return circulator is started, the internal circulation pump operates, allowing water to enter the circulator through the inlet pipe. At this time, the nanofiltration membrane 15 on one side of the inlet pipe filters impurities in the water. When the nanofiltration membrane 15 needs replacement, the rotating rod 9 is rotated, causing it to rotate within the groove 5. Simultaneously, the rotating rod 9 drives the squeezing rod 10, causing it to move in a small circular motion within the groove 5. When the outer surface of the squeezing rod 10 contacts the outer wall of the pressure plate 8, the squeezing rod 10 drives the pressure plate 8, causing it to slide within the groove 5. The pressure plate 8 then drives the positioning rod 7, causing it to slide within the groove 5. The positioning rod 7 slides on the outer wall of the fixing rod 6. During the movement, the positioning rod 7 simultaneously compresses the spring 13. At this time, one end of the positioning rod 7 slides inside the filter tank 4, causing one end of the positioning rod 7 to separate from the positioning groove 12. This pulls the filter frame 11, causing it to slide inside the filter tank 4 and move out of the filter tank 4. This makes it easier to replace the nanofiltration membrane 15 inside the filter frame 11. When the nanofiltration membrane 15 inside the filter frame 11 has been replaced, the filter frame 11 is moved into the filter tank 4, with the positioning groove 12 located on one side of the positioning rod 7. At this time, the rotating rod 9 is released, and the elastic force of the spring 13 drives the positioning rod 7 to move, causing one end of the positioning rod 7 to enter the positioning groove 12. The filtration of water by the nanofiltration membrane 15 inside the filter frame 11 will not be affected.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: a water circulation device with a scale filtration structure, wherein an installation groove 16 is provided on one side of the outer wall of the mounting plate 14, and a threaded rod 17 passes through the inside of the filter frame 11. The threaded rod 17 is connected to the filter frame 11 by threads. When the positioning rod 7 moves, one end of the positioning rod 7 will move inside the filter groove 4, so that one end of the positioning rod 7 is separated from the positioning groove 12.

[0028] In a preferred embodiment, one end of the threaded rod 17 is slidably connected to the mounting groove 16. When the threaded rod 17 moves, one end of the threaded rod 17 will separate from the mounting groove 16, so that the subsequent mounting plate 14 can be easily removed from the inside of the filter frame 11.

[0029] The working principle of this utility model is as follows: When it is necessary to disassemble the nanofiltration membrane 15 of the filter frame 11, the threaded rod 17 is rotated. The threaded rod 17 moves with the filter frame 11 through the thread, so that one end of the threaded rod 17 can be slowly moved out of the mounting groove 16. At this time, the mounting plate 14 is pulled to move, so that the mounting plate 14 moves the nanofiltration membrane 15 out of the filter frame 11, thereby making it convenient to replace the nanofiltration membrane 15 in the future.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
