Description

Technical Field

[0001] The invention relates to the technical field of groundwater pollution control, and in particular to a multi-layer filtering and purification device for groundwater pollution prevention and control. Background Art

[0002] Groundwater refers to water stored in the gaps in rocks below the ground. Groundwater is one of the important water resources on the earth. The exploitation and utilization of groundwater is of great significance to mankind. Groundwater is rich in minerals and cannot be used directly. Filtration and purification equipment is required. Filtration and purification equipment is also of great significance for the prevention and control of groundwater pollution.

[0003] In some rural areas, groundwater is one of the main water sources for residents. The existing multi-layer filtration and purification equipment for groundwater pollution prevention and control used by residents usually filters groundwater through PP cotton filter cartridges, granular activated carbon filter cartridges, and carbon rod filter cartridges arranged in parallel, then enters the reverse osmosis membrane for filtration, and finally passes through a composite filter element to connect to the faucet. The groundwater passes through the filtration equipment and comes out of the faucet to become pure drinkable water. The above-mentioned filtering equipment needs to replace the filter element after being used for a period of time, especially PP cotton filter element, granular activated carbon filter element and carbon rod filter element need to be replaced frequently, otherwise it will seriously affect the water quality. When residents use this filtering equipment, the distance between the PP cotton filter cartridge, granular activated carbon filter cartridge and carbon rod filter cartridge is usually connected by a pipe through a filter cover, and the filter cover and the filter cartridge are tightly connected by a thread. When replacing the filter element, the filter cover is usually kept stationary and disassembled by rotating the filter cartridge. Then, in order to save volume, the distance between the two filter cartridges is usually relatively small. In order to prevent water leakage, the filter cover and the filter element are connected tightly. When the filter element needs to be replaced and the filter cartridge and the filter cover need to be disassembled, and the filter element needs to be installed after replacement, it is usually difficult to directly rotate it or install it by hand. A tool needs to be used to clamp the filter cartridge for rotation. However, because the distance between the two filter cartridges is relatively small, when the tool is used to rotate it again, the handle usually cannot pass between the two filter cartridges, and can only be rotated a small angle each time, making the disassembly process difficult. Summary of the invention

[0029] Reference Figures 1 to 5 , Figure 1 A front view of a multi-layer filtering and purification device for preventing and controlling groundwater pollution provided by an embodiment of the present invention, Figure 2 This is a left view of a multi-layer filtering and purification device for preventing and controlling groundwater pollution provided by an embodiment of the present invention. Figure 3 A cross-sectional view under the left view of a multi-layer filtering and purification device for preventing and controlling groundwater pollution provided by an embodiment of the present invention, Figure 4 for Figure 3 A schematic diagram of the enlarged local structure of the A area in the middle. Figure 5 A cross-sectional view of a multi-layer filtering and purification device for preventing and controlling groundwater pollution provided by an embodiment of the present invention under a top view. Figures 1 to 5As shown, a multi-layer filtering and purification device for preventing and controlling groundwater pollution includes three filter cartridges arranged in parallel, each of which includes a cartridge cover 1 and a cartridge body 2 screwed to the cartridge cover 1, and also includes a rotating mechanism connected to the three cartridge bodies 2 respectively, and the three filter cartridges are respectively equipped with a PP cotton filter element, a granular activated carbon filter element and a carbon rod filter element, and the rotating mechanism includes: a connecting sleeve 4, a spur gear transmission system 3 and a rotating shaft 5, the connecting sleeve 4 is sleeved on the cartridge body 2 through a bearing, the spur gear transmission system 3 is located in the connecting sleeve 4, the first cone wheel 30 of the spur gear transmission system 3 is fixedly sleeved on the cartridge body 2, the second cone wheel 31 of the spur gear transmission system 3 is meshed with the first cone wheel 30, so that the cartridge body 2 rotates when the second cone wheel 31 is rotated, one end of the rotating shaft 5 is connected to the second cone wheel 31, and the other end of the rotating shaft 5 is penetrated through the connecting sleeve 4, so that the rotating shaft 5 rotates to drive the cartridge body 2 to rotate, thereby realizing the separation of the cartridge body 2 and the cartridge cover 1.

[0030] The first cone wheel is meshed with the second cone wheel of the spur gear transmission system, and the second cone wheel of the spur gear transmission system is meshed with the first cone wheel, so that the second cone wheel of the spur gear transmission system can be rotated to rotate the cylinder body, and the rotation direction of the second cone wheel of the spur gear transmission system is perpendicular to the rotation direction of the cylinder body, one end of the rotating shaft is connected to the second cone wheel, and the connecting sleeve is passed through the other end of the rotating shaft. The connecting sleeve makes the second cone wheel more stable, and the rotating shaft extends out of the connecting sleeve, so that the second cone wheel rotates when the rotating shaft is rotated, so that the cylinder cover is fixed, and the rotating shaft can make the cylinder body rotate, so that the cylinder body and the cylinder cover are separated, and the rotation direction of the rotating shaft is the same as the rotation direction of the second cone wheel, and is perpendicular to the rotation direction of the first cone wheel, that is, the rotating shaft does not need to pass between the two cylinders, which makes the disassembly process of the cylinder body easier. When in use, the cylinder cover is fixed, the connecting sleeve is fixed by hand or other tools, and the cylinder body can be rotated by rotating the rotating shaft to realize the separation of the cylinder body and the cylinder cover.

[0031] The length of the rotating shaft 5 extending out of the connecting sleeve 4 is 3 cm-5 cm, which avoids the rotating shaft 5 extending out of the connecting sleeve too short, making it difficult to rotate the rotating shaft 5, and also avoids the length being too long, making it take up a large space.

[0032] Refer again Figure 1 As shown, one end of the rotating shaft 5 extending out of the connecting sleeve 4 is connected to a rotating disk 6. Rotating the rotating disk 6 rotates the rotating shaft 5, making it easier to rotate the rotating shaft 5, and further making it easier to disassemble the cylinder body 2 and the cylinder cover 1.

[0033] The thickness of the turntable 6 is 2cm-4cm, which avoids being too thin and easily damaged when rotating, and also avoids being too thick and taking up space, increasing weight, and being difficult to rotate, further making it easier to disassemble the cylinder body 2 and the cylinder cover 1.

[0034] Refer again Figure 1 As shown, it also includes a connecting rod 7, which is connected to the three rotating disks 6 respectively, so that the three rotating disks 6 can rotate simultaneously.

[0035] A stepping motor is connected to the turntable 6 on the cylinder 2 where the granular activated carbon filter element is located. The stepping motor is in the middle, so the force is more evenly applied.

[0036] The connecting rod 7 and the rotating disk 6 are detachably connected, so that the three cylinders can be detached separately or simultaneously.

[0037] The rotating disk 6 and the connecting rod 7 are connected by a buckle, so that the rotating disk 6 and the connecting rod 7 are easier to disassemble.

[0038] The height of the connecting sleeve 4 is 3 cm-5 cm, so that the connecting sleeve 4 has the smallest volume while ensuring the stability of the spur bevel gear transmission system.

[0039] The distance between the connecting sleeve 4 and the cylinder cover 1 is 5 cm-8 cm, which makes it easier for the cylinder body to rotate and further makes it easier for the cylinder body 2 and the cylinder cover 1 to be disassembled.

[0040] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
