Description

Technical Field

[0001] This utility model is a hexavalent chromium removal device, belonging to the field of hexavalent chromium removal. Background Technology

[0002] As is well known, hexavalent chromium has strong oxidizing properties and poses a significant threat to human health. Long-term exposure to hexavalent chromium may lead to carcinogenicity, increasing the risk of respiratory system tumors such as lung cancer and nasopharyngeal carcinoma. Therefore, hexavalent chromium is often removed during drinking water filtration. Currently, the method for removing hexavalent chromium involves installing a detachable hexavalent chromium removal device at the ends of two water pipes. This device consists of pipes containing A-21S chromium removal special resin. When water enters another water pipe, it passes through the A-21S chromium removal special resin, thus filtering out the hexavalent chromium in the water.

[0003] However, most hexavalent chromium removal devices currently on the market do not have an exposed water pipe during the disassembly and replacement process. As a result, the water valve must be closed when replacing the hexavalent chromium removal device, and then the water valve must be opened again after the replacement is completed. This makes the replacement process cumbersome and causes unnecessary trouble for the staff. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hexavalent chromium removal device to solve the problems mentioned in the background art. This utility model does not require manual shutting off and starting of water flow when replacing special resin, which brings great convenience to the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hexavalent chromium removal device, comprising a first pipe, a second pipe, and a filter pipe. The first pipe has an installation groove at its top, and the inner wall of the installation groove is provided with a sealing component. The inner wall of the installation groove also has a threaded groove. The filter pipe has a sliding groove at its top, and a spring is fixedly connected to the inner bottom wall of the sliding groove. A bolt tube is connected to the top of the spring, and a bearing is embedded in the top of the bolt tube. An installation tube is fixedly connected to the inner ring of the bearing. The installation tube has a groove at its top, and a toothed plate is fixedly connected to the inner wall of the groove. The inner wall of the filter pipe is provided with a special resin.

[0006] Furthermore, the sealing component includes a plug, which is rotatably connected inside the first pipe. The plug has a "spherical" structure, and its outer wall has a water inlet channel. When filtering water, water can pass through the water inlet channel.

[0007] Furthermore, a rotating shaft is rotatably sleeved on the outer wall of the block, and a gear is fixedly sleeved on the outer wall of the rotating shaft, the gear being located inside the mounting groove.

[0008] Furthermore, the mounting tube is slidably sleeved with the mounting groove, the bolt tube extends into the interior of the mounting groove, and the bolt tube is threadedly connected to the threaded groove. By rotating the bolt tube and the filter pipe, the bolt tube disengages from the threaded groove, allowing the filter pipe to be disassembled.

[0009] Furthermore, one end of the rotating shaft passes through the first pipe and extends into the interior of the mounting groove. The rotating shaft is rotatably connected to the first pipe, and the toothed plate is meshed with the gear. Thus, when rotating the bolt pipe and the filter pipe, the bolt pipe disengages from the threaded groove. When the bolt pipe moves into the interior of the mounting groove, the toothed plate drives the gear and the rotating shaft to rotate, thereby causing the block to rotate and the water inlet channel to rotate ninety degrees.

[0010] Furthermore, a limiting rod is fixedly connected to the inner bottom wall of the mounting groove, and a limiting groove is opened at the top of the mounting tube. The limiting groove and the limiting rod are slidably sleeved together. The limiting rod can play a positioning role. Thus, the limiting groove and the limiting rod can be inserted together so that when the filter pipe is installed, the groove can be accurately sleeved on the outside of the rotating shaft.

[0011] The beneficial effects of this utility model are:

[0012] 1. Through the designed plug, gears, filter pipes, water inlet channel, and toothed plate, when the filter pipe is disassembled, the plug will rotate 90 degrees, aligning the water inlet channel with the inner wall of the first pipe. Consequently, the top and bottom of the plug become solid, sealing the first pipe. The plug inside the second pipe seals the inner wall of the second pipe using the same principle. This ensures that when the special resin is replaced, the ports of the first and second pipes are not leaking. This eliminates the need to manually turn the water flow on and off during the replacement of the special resin, providing significant convenience for staff.

[0013] 2. After replacing the special resin using the filter pipe, bolt pipe, and installation pipe, press the installation pipes at both ends of the filter pipe into the sliding groove, then align the filter pipe with the ports of the first and second pipes. The bolt pipe enters the installation groove through a spring, and the bolt pipe is rotated to connect with the threaded groove, thus installing the filter pipe. This makes the disassembly and installation process of the device simple and convenient, improving the efficiency of replacing the special resin. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a hexavalent chromium removal device, including a first pipe 1, a second pipe 2, and a filter pipe 3. The top of the first pipe 1 is provided with an installation groove 4, and the inner wall of the installation groove 4 is provided with a sealing component. The inner wall of the installation groove 4 is provided with a threaded groove 18. The top of the filter pipe 3 is provided with a sliding groove 11, and a spring 10 is fixedly connected to the inner bottom wall of the sliding groove 11. The top of the spring 10 is connected to a bolt tube 12, and a bearing 13 is embedded in the top of the bolt tube 12. The inner ring of the bearing 13 is fixedly connected to an installation tube 14, and a groove 16 is provided in the top of the installation tube 14. A toothed plate 17 is fixedly connected to the inner wall of the groove 16. The inner wall of the filter pipe 3 is provided with a special resin 19. The structure on the first pipe 1 and the structure on the second pipe 2 are the same. The first pipe 1 and the second pipe 2 are mirror images of each other. The structures at both ends of the filter pipe 3 are the same.

[0022] The sealing component includes a plug 5, which is rotatably connected inside the first pipe 1. The plug 5 has a "spherical" structure, and the outer wall of the plug 5 has a water inlet channel 8. When filtering water, water can pass through the water inlet channel 8.

[0023] The outer wall of the block 5 is rotatably fitted with a rotating shaft 6, and the outer wall of the rotating shaft 6 is fixedly fitted with a gear 7, which is located inside the mounting groove 4.

[0024] The mounting tube 14 is slidably sleeved with the mounting groove 4, and the bolt tube 12 extends into the interior of the mounting groove 4. The bolt tube 12 is threadedly connected to the threaded groove 18. When the bolt tube 12 and the filter pipe 3 are rotated, the bolt tube 12 is disengaged from the threaded groove 18, which allows the filter pipe 3 to be disassembled.

[0025] One end of the rotating shaft 6 passes through the first pipe 1 and extends into the interior of the mounting groove 4. The rotating shaft 6 is rotatably connected to the first pipe 1. The toothed plate 17 is meshed with the gear 7. When the rotating bolt pipe 12 and the filter pipe 3 are rotated, the bolt pipe 12 disengages from the threaded groove 18. When the bolt pipe 12 moves into the interior of the mounting groove 4, the toothed plate 17 drives the gear 7 and the rotating shaft 6 to rotate, which in turn causes the block 5 to rotate and the water inlet channel 8 to rotate ninety degrees.

[0026] The inner bottom wall of the mounting groove 4 is fixedly connected to the limiting rod 9, and the top of the mounting tube 14 is provided with a limiting groove 15. The limiting groove 15 and the limiting rod 9 are slidably sleeved together. The limiting rod 9 can play a positioning role. Then, the limiting groove 15 and the limiting rod 9 can be inserted together so that when the filter pipe 3 is installed, the groove 16 can be accurately sleeved on the outside of the rotating shaft 6.

[0027] Working principle: First, when the special resin 19 needs to be replaced, when the bolt tube 12 and the filter pipe 3 are rotated, the bolt tube 12 disengages from the threaded groove 18. When the bolt tube 12 moves into the installation groove 4, the toothed plate 17 moves upward, and the toothed plate 17 drives the gear 7 and the rotating shaft 6 to rotate, and the block 5 rotates ninety degrees.

[0028] Secondly, after the plug 5 is rotated 90 degrees, the water inlet channel 8 will be directly facing the inner wall of the first pipe 1, and the top and bottom of the plug 5 will be solid. The plug 5 will seal the first pipe 1. The plug 5 inside the second pipe 2 will seal the inner wall of the second pipe 2 through the same principle, so that when the special resin 19 is replaced, the ports of the first pipe 1 and the second pipe 2 will not be in an external leakage state.

[0029] Finally, after replacing the special resin 19, press the mounting tubes 14 on both ends of the filter pipe 3 into the inside of the slide groove 11 so that the filter pipe 3 is aligned with the ports of the first pipe 1 and the second pipe 2. Then loosen the mounting tubes 14, and the spring force of the spring 10 will extend into the inside of the mounting groove 4. Rotate the bolt tube 12 to connect with the threaded groove 18, and the filter pipe 3 can be installed.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
