Description

Technical Field

[0001] This utility model relates to the field of rural water purification technology, specifically a purification device for non-metallic mineral pollution in rural drinking water. Background Technology

[0002] Since rural water sources in mountainous areas mostly draw water from natural mountain springs flowing down from the mountains, the water sources often contain non-metallic minerals washed down from the mountains. These non-metallic minerals exist in the water as particulate impurities, making the water turbid, muddy, and unsuitable for direct drinking. Therefore, the water sources in rural mountainous areas need to be purified to remove non-metallic mineral pollution before they can be used directly for daily purposes.

[0003] However, existing purification equipment mostly relies on physical filtration combined with activated carbon adsorption to purify water in mountainous rural areas, and is equipped with cleaning brushes for rotating cleaning. However, the water contains a lot of non-metallic minerals, and the filter screen is particularly easy to clog during the initial filtration. In order to ensure the normal purification of the water source, the filter screen needs to be cleaned frequently with a brush. However, frequent cleaning will cause wear and tear on the filter screen and affect the service life of the purification equipment. Utility Model Content

[0004] The purpose of this invention is to provide a purification device for non-metallic mineral pollution in rural drinking water, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification device for non-metallic mineral pollution in rural drinking water, comprising a purification cylinder, an adsorption cylinder installed inside the purification cylinder, a filter cylinder passing through the middle of the adsorption cylinder, a bearing installed at the bottom of the filter cylinder and the bottom surface of the purification cylinder, an inner connecting cylinder connected to the inner wall of the filter cylinder, an outer connecting cylinder connected to the outer wall of the filter cylinder, a filter brush connected to the inner wall of the inner connecting cylinder, a cleaning brush connected to the outer wall of the outer connecting cylinder, a cover plate fitted on the top of the filter cylinder, a through hole opened in the middle of the cover plate, an inlet pipe movably inserted into the through hole, an outlet pipe connected to one side wall of the purification cylinder, and an outlet valve installed on the outlet pipe.

[0006] Preferably, a fixing ring is connected to the outer wall of the top of the adsorption cylinder, a thread is provided on the outer wall of the bottom of the adsorption cylinder, a sealing plate is connected to the outer wall of the adsorption cylinder above the thread, the adsorption cylinder is a cylindrical shape with hollow side walls, a filter screen is connected to both the inner and outer side walls of the adsorption cylinder, and activated carbon particles are filled inside the side walls of the adsorption cylinder.

[0007] Preferably, the outer diameter of the adsorption cylinder is adapted to the inner diameter of the bottom surface of the purification cylinder, and the adsorption cylinder is threadedly connected to the inner wall of the purification cylinder.

[0008] Preferably, the filter cylinder has filter holes through its sidewall, and the inner and outer walls of the filter cylinder are provided with sliding grooves. The bottom of the filter cylinder is rotatably connected to the purification cylinder via a bearing.

[0009] Preferably, both the outer wall of the inner connecting cylinder and the inner wall of the outer connecting cylinder are connected to sliders, the width of the sliders is adapted to the width of the inner wall of the slide groove, and the sliders are movably inserted into the slide groove.

[0010] Preferably, an annular groove is provided through the cover plate at a position corresponding to the filter cylinder. Rubber rings are installed on the inner walls of both sides of the annular groove. The filter cylinder passes through the cover plate through the annular groove, and the cover plate covers the top of the adsorption cylinder, the inner connecting cylinder, and the outer connecting cylinder.

[0011] Preferably, the filter cartridge and the adsorption cartridge separate the inner cavity of the purification cartridge from the inside out to form a water inlet chamber and a water outlet chamber, the water inlet pipe is connected to the water inlet chamber, and the water outlet chamber is connected to the water outlet pipe.

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

[0013] This rural drinking water non-metallic mineral pollution purification device, through the installation of an inner connecting cylinder, an outer connecting cylinder, filter brushes, and cleaning brushes, allows water entering the inlet chamber to first contact the filter brushes. Large non-metallic mineral particles in the water are intercepted by the gaps in the filter brushes, followed by the filter holes that also intercept large impurities. The water then enters between the filter cylinder and the adsorption cylinder, where the filter screen continues to filter out particulate impurities. This allows the water to carry fine particles into the inner wall of the purification cylinder, where activated carbon particles adsorb these fine impurities before the water flows into the drain chamber and is discharged. Building upon the original filter screen filtration and activated carbon particle adsorption, the device adds the interception effect of filter brushes and filter holes for large non-metallic mineral impurities. When the cleaning brushes clean the inner filter screen of the adsorption cylinder, some large particles adhere evenly to the gaps in the filter brushes, preventing large particles from accumulating on the outer wall of the filter screen and causing frequent clogging. This reduces the frequency of cleaning the filter screen with the cleaning brushes and decreases wear.

[0014] This rural drinking water non-metallic mineral pollution purification device uses a slider, a chute, and a cover plate. By pulling the cover plate upwards, the cover plate moves upwards relative to the filter cylinder and is removed from the top of the filter cylinder. Then, pulling the inner and outer connecting cylinders upwards causes the inner and outer connecting cylinders to move the slider upwards in the chute. The inner and outer connecting cylinders then move the filter brush and cleaning brush upwards respectively until they are pulled out from above the filter cylinder, thus achieving the detachability of the cleaning brush and filter brush, making it easy to clean large particle impurities remaining on the filter brush.

[0015] This rural drinking water non-metallic mineral pollution purification device uses a fixed ring, a sealing plate, and threads. By rotating the fixed plate, the adsorption cylinder rotates, and the adsorption cylinder moves upward through the threads inside the purification cylinder, allowing the adsorption cylinder to be removed from the purification cylinder for easy replacement of the activated carbon particles inside.

[0023] like Figures 1 to 4As shown, the non-metallic mineral pollution purification device for rural drinking water in this embodiment includes a purification cylinder 1. An adsorption cylinder 2 is installed inside the purification cylinder 1 to store activated carbon particles. A filter cylinder 4 is installed through the middle of the adsorption cylinder 2 to filter large non-metallic mineral impurities. A bearing 5 is installed at the bottom of the filter cylinder 4 and the bottom surface of the purification cylinder 1. An inner connecting cylinder 6 is connected to the inner wall of the filter cylinder 4, and an outer connecting cylinder 7 is connected to the outer wall of the filter cylinder 4. Filter brushes 8 are connected to the inner wall of the inner connecting cylinder 6. The filter brushes 8 are radiating outwards, meaning that the closer to the inner connecting cylinder 6... The narrower the side, the more the filter brush 8 intercepts large non-metallic mineral particles in the water source through its divergent gaps. The outer wall of the outer connecting cylinder 7 is connected to a cleaning brush 9 for cleaning the filter screen 3 inside the adsorption cylinder 2. A cover plate 13 is fitted on the top of the filter cylinder 4 to cover the adsorption cylinder 2 and the filter cylinder 4. A through hole 16 is opened in the middle of the cover plate 13. An inlet pipe 17 is movably inserted into the through hole 16. The inlet pipe 17 is connected to an unpurified water source. An outlet pipe 18 is connected to one side wall of the purification cylinder 1. An outlet valve 19 is installed on the outlet pipe 18.

[0024] Specifically, a fixing ring 12 is connected to the outer wall of the top of the adsorption cylinder 2. The fixing ring 12 is located on the upper surface of the purification cylinder 1 and seals the opening at the top of the purification cylinder 1. A thread 20 is provided on the outer wall of the bottom of the adsorption cylinder 2. Similarly, a thread 20 is also provided on the inner wall of the purification cylinder 1. A sealing plate 21 is connected to the outer wall of the adsorption cylinder 2 above the thread 20. The sealing plate 21 is a ring made of rubber. After the adsorption cylinder 2 is connected to the purification cylinder 1, the sealing plate 21 seals the threaded connection. The adsorption cylinder 2 is a cylindrical shape with hollow side walls. Filter screens 3 are connected to both the inner and outer side walls of the adsorption cylinder 2. The filter screen 3 on the inner side is used to adsorb impurities before adsorption. The filter screen 3 on the outer side is used to separate activated carbon particles and adsorbed fine particles from the water flow. The inside of the side wall of the adsorption cylinder 2 is filled with activated carbon particles.

[0025] Furthermore, the outer diameter of the adsorption cylinder 2 is matched with the inner diameter of the bottom surface of the purification cylinder 1. The adsorption cylinder 2 is threadedly connected to the inner wall of the purification cylinder 1 via a thread 20. By rotating the fixing plate, the fixing plate drives the adsorption cylinder 2 to rotate. The adsorption cylinder 2 rotates and moves upward within the purification cylinder 1 via the thread 20, allowing the adsorption cylinder 2 to be removed from the purification cylinder 1 for easy replacement of the activated carbon particles inside the adsorption cylinder 2.

[0026] Furthermore, filter holes 24 are provided through the side wall of filter cylinder 4 to perform secondary physical filtration of water source through filter holes 24. Sliding grooves 22 are provided on both the inner and outer walls of filter cylinder 4. The bottom of filter cylinder 4 is rotatably connected to purification cylinder 1 via bearing 5. By rotating filter cylinder 4, filter cylinder 4 can drive cleaning brush 9 to rotate relative to adsorption cylinder 2 via outer connecting cylinder 7, so that cleaning brush 9 can periodically clean the filter screen 3 inside adsorption cylinder 2.

[0027] Furthermore, sliders 23 are connected to the outer side wall of the inner connecting cylinder 6 and the inner side wall of the outer connecting cylinder 7. There are several sliders 23, which are arranged equidistantly along the outer side wall of the inner connecting cylinder 6 and the inner side wall of the outer connecting cylinder 7. The width of the sliders 23 is adapted to the width of the inner wall of the slide groove 22. The sliders 23 are movably inserted into the slide groove 22. By inserting the sliders 23 into the slide groove 22, the inner connecting cylinder 6 and the outer connecting cylinder 7 can be rotated when the filter cylinder 4 rotates. By pulling the inner connecting cylinder 6 and the outer connecting cylinder 7 upward, the inner connecting cylinder 6 and the outer connecting cylinder 7 drive the sliders 23 to move upward in the slide groove 22. The inner connecting cylinder 6 and the outer connecting cylinder 7 respectively drive the filter brush 8 and the cleaning brush 9 to move upward until they are pulled out from above the filter cylinder 4, realizing the detachability of the cleaning brush 9 and the filter brush 8.

[0028] Furthermore, an annular groove 14 is provided on the cover plate 13 at a position corresponding to that of the filter cylinder 4. Rubber rings 15 are installed on the inner walls of both sides of the annular groove 14. The filter cylinder 4 passes through the cover plate 13 through the annular groove 14. The cover plate 13 covers the top of the adsorption cylinder 2, the inner connecting cylinder 6, and the outer connecting cylinder 7. By pulling the cover plate 13 upward, the cover plate 13 can be moved upward relative to the filter cylinder 4 and removed from the top of the filter cylinder 4. After the cover plate 13 is fitted on the filter cylinder 4, the rubber rings 15 contact the side wall of the filter cylinder 4, increasing the friction between the filter cylinder 4 and the cover plate 13. It needs to be installed by manual pressing.

[0029] Furthermore, the filter cartridge 4 and the adsorption cartridge 2 divide the inner cavity of the purification cartridge 1 from the inside out to form an inlet chamber 11 and a drain chamber 10. The inlet pipe 17 is connected to the inlet chamber 11, and the drain chamber 10 is connected to the outlet pipe 18. The unpurified water source enters the inlet chamber 11 from the inlet pipe 17, passes through three stages of physical filtration, is adsorbed by activated carbon, and finally enters the drain chamber 10.

[0030] The usage method of this embodiment is as follows: When the user uses the purification device to purify non-metallic mineral pollution in the water of rural mountainous areas, the water source is first introduced into the water inlet chamber 11 through the water inlet pipe 17. The water source flows towards the drain chamber 10 due to the water level pressure difference. The water source first contacts the filter brush 8, and the gaps in the filter brush 8 intercept large non-metallic mineral particles in the water source. Then, the filter holes 24 intercept large impurities. The water source passing through the filter holes 24 enters between the filter cylinder 4 and the adsorption cylinder 2. After passing through the cleaning brush 9, the filter screen 3 continues to filter out particulate impurities, allowing the water source carrying fine particulate impurities to pass through the filter screen 3 and fully contact the activated carbon particles. After the activated carbon particles adsorb the fine impurities in the water, the water flows through the filter screen 3 and into the drain chamber 10. After the outlet valve 19 is opened, it is discharged from the outlet pipe 18. When the filter screen 3 inside the adsorption chamber becomes clogged after long-term use, the filter cylinder 4 is rotated by turning it from above the device. The filter cylinder 4 drives the slider 23 to rotate through the inner wall of the slide groove 22. The slider 23 drives the outer connecting cylinder 7 to rotate, and the outer connecting cylinder 7 drives the cleaning brush 9 to rotate relative to the adsorption cylinder 2, so that the cleaning brush 9 cleans the surface of the filter screen 3 inside the adsorption cylinder 2. When too much impurity is brushed off by the cleaning brush 9 and too many large particles of impurity are intercepted on the filter brush 8, pull the cover plate 13 upward, so that the cover plate 13 moves upward relative to the filter cylinder 4 and is removed from the top of the filter cylinder 4. Then pull the inner connecting cylinder 6 and the outer connecting cylinder 7 upward, so that the inner connecting cylinder 6 and the outer connecting cylinder 7 drive the slider 23 to move upward in the slide groove 22. The inner connecting cylinder 6 and the outer connecting cylinder 7 drive the filter brush 8 and the cleaning brush 9 to move upward respectively, until they are pulled out from the top of the filter cylinder 4, and the cleaning brush 9 and the filter brush 8 are rinsed. When the adsorption effect of the activated carbon particles decreases due to long-term use, remove the cover plate 13, turn the fixing plate to rotate, and the fixing plate drives the adsorption cylinder 2 to rotate. The adsorption cylinder 2 rotates and moves upward in the purification cylinder 1 through the thread 20, so that the adsorption cylinder 2 is removed from the purification cylinder 1 and the activated carbon particles are replaced.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
