Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and more specifically, to a high-efficiency water pollution control device. Background Technology

[0002] In the current field of water pollution control, traditional water treatment methods mainly include physical, chemical, and biological treatment. While these methods can remove pollutants from water to a certain extent, they often suffer from low treatment efficiency, large land area requirements, high operating costs, and the potential for secondary pollution. Furthermore, traditional treatment facilities require highly skilled operators and are difficult to adapt to complex and changing water quality conditions, resulting in unsatisfactory water pollution control outcomes.

[0003] Utility model patent CN215161588U discloses a high-efficiency water pollution treatment device, including a sewage treatment tank. The tank contains a primary filtration structure and a secondary filtration structure. The secondary filtration structure includes a drive shaft, a rotating slide rod, and a suspended adsorption net. The drive shaft and slide rod are fixedly connected, and the drive shaft is rotatably connected to the sewage treatment tank. The suspended adsorption net is slidably connected to the slide rod via a connecting assembly, on which a second magnet is fixedly installed. A first magnet is installed on the inner wall of the sewage treatment tank, and the first and second magnets are movably connected. A spring assembly is fitted onto the slide rod, and this spring assembly is connected to the connecting assembly. This utility model effectively removes solids and suspended matter from sewage through its two-stage filtration structure. The suspended adsorption net, under the action of the first and second magnets and the spring assembly, reciprocates on the rotating slide rod, resulting in a wider absorption range for suspended matter in the sewage and higher treatment efficiency.

[0004] Although the above technical solution performs two filtration and purification treatments on the sewage through the primary and secondary filtration structures, the treatment effect is not sufficient. For example, the pollutants filtered out by the primary filtration structure are not treated in a timely manner, which may cause secondary pollution. Also, although the suspended adsorption net moves back and forth on the slide bar, it does not always completely cover the entire sewage area inside the sewage treatment tank, which may result in insufficient filtration. In view of this, we propose an effective and feasible solution that can solve the above-mentioned shortcomings, namely, a high-efficiency water pollution treatment device. Utility Model Content

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please see Figures 1-7 A high-efficiency water pollution treatment device includes a filter box mechanism 1. The filter box mechanism 1 includes a filter box body 11 with an open top. A U-shaped top cover 5 is detachably fitted on the top of the filter box body 11. A cleaning component 4 is installed in the middle between the two opposing vertical inner side walls of the U-shaped top cover 5 to ensure the cleanliness of the inside of the filter box body 11 and improve the filtration effect. A primary filter component 2 with a horizontal cross-sectional shape and size adapted to the filter box body 11 is installed near the upper end of the filter box body 11. A secondary filter component 3 with a sliding connection to the filter box body 11 is provided directly below the primary filter component 2. The polluted water is filtered twice, which greatly improves the filtration effect.

[0033] Specifically, the primary filter assembly 2 includes a mounting ring 21 fixedly connected to the inner peripheral wall of the filter box body 11. A primary filter screen 22 is detachably provided on the top surface of the mounting ring 21. A collection assembly 6 is provided on an outer side wall of the filter box body 11 above the primary filter assembly 2. Larger pollutants are filtered through the primary filter screen 22. The filtered pollutants are then centrally removed by the cleaning assembly 4 and the collection assembly 6, achieving preliminary filtration of the water. The detachable primary filter screen 22 allows for periodic surface cleaning or replacement, extending the service life of this embodiment. It also allows for periodic replacement of the activated carbon in the secondary filter assembly 3, ensuring optimal filtration of water pollution.

[0034] Furthermore, the secondary filtration assembly 3 includes a first motor 31 located at the lower end of one outer wall of the filter box body 11. The output shaft of the first motor 31 passes through one side wall of the filter box body 11 and is coaxially fixedly connected to a drive bevel gear shaft 32. The drive bevel gear shaft 32 is vertically meshed with a driven bevel gear shaft 33 that is rotatably connected to the inner bottom surface of the filter box body 11. A vertical lead screw 34 is coaxially fixedly connected to the top of the driven bevel gear shaft 33. A sliding cross support plate 35 is threaded on the outer side of the vertical lead screw 34. An activated carbon tank 36 with several evenly distributed drainage holes is fixedly provided on the top surface of the sliding cross support plate 35, which is always in contact with and slidably connected to the inner peripheral wall of the filter box body 11. The vertical lead screw 34 is inserted through and inserted into the center of the bottom of the activated carbon tank 36. At least one of the two opposing vertical side walls inside the filter box body 11 is provided. Two sliding grooves 14 are used to slide the activated carbon tank 36. The outer side of the vertical wall of the activated carbon tank 36 is provided with sliding strips 37, which are equal in number and correspond one-to-one with the sliding grooves 14. The activated carbon tank 36 can be filled with activated carbon. Utilizing the adsorption capacity of activated carbon, the water that has already undergone primary filtration treatment is subjected to secondary filtration treatment, and all organic pollutants and heavy metal ions in the water are filtered out, which further greatly improves the filtration effect. The first motor 31 drives the active bevel gear shaft 32 to rotate. The active bevel gear shaft 32 drives the driven bevel gear shaft 33. The driven bevel gear shaft 33 rotates the vertical screw 34. The rotation of the vertical screw 34 drives the sliding cross support plate 35 to slide, thereby realizing the up and down sliding of the activated carbon tank 36. This facilitates the periodic replacement of activated carbon and ensures a higher quality filtration effect for the water.

[0035] It should be further explained that the vertical lead screw 34 is fitted with a telescopic sleeve 38 above the activated carbon tank 36, which is fixedly connected to the bottom of the activated carbon tank 36. When the slide bar 37 is at the bottom of the slide groove 14, the telescopic sleeve 38 is stretched to its longest state. The telescopic sleeve 38 isolates the interference caused by the activated carbon particles to the rotation of the vertical lead screw 34, ensuring that the vertical lead screw 34 can rotate normally.

[0036] In this embodiment, the upper outer side of the filter box body 11 is detachably connected to the U-shaped top cover 5 by an L-shaped limiting ring 12, providing feasible conditions for cleaning or replacing the primary filter screen 22 and replacing the activated carbon. The filter box body 11 has a horizontal cross-section funnel-shaped drain outlet 13 connected to the collection component 6 on the vertical side wall of the side where the collection component 6 is located. The bottom of the drain outlet 13 is convex upward in the middle, which is conducive to the centralized collection of pollutants.

[0037] In this embodiment, a water inlet pipe 15 is provided on one side wall of the filter box body 11 above the primary filter component 2 to facilitate the loading and treatment of polluted water. A water outlet pipe 16 is provided on one side wall of the filter box body 11 below the secondary filter component 3, through which the filtered water is transported to various required locations. A sealing ring is rotatably sleeved on the outside of the active bevel gear shaft 32 and fixedly snapped into the corresponding side wall of the filter box body 11. The setting of the sealing ring can improve the sealing performance of the filter box body 11.

[0038] In this embodiment, the cleaning assembly 4 includes a second motor 41 fixedly mounted on the vertical outer wall of the U-shaped top cover 5 opposite to the drain outlet 13, providing kinetic energy for cleaning. The output shaft of the second motor 41 passes through the vertical side wall of the U-shaped top cover 5 and is coaxially fixedly connected to a transverse lead screw 42. A slider 43 is threadedly connected to the outer side of the transverse lead screw 42. The bottom surface of the slider 43 is provided with a first electric push rod 44. Through the retraction function of the first electric push rod 44, the cleaning blade 45 can be moved away from the top surface of the primary filter screen 22. This can prevent the cleaning blade 45 from bringing the pollutants back to the end away from the drain outlet 13 during the movement away from the drain outlet 13. The bottom of the telescopic rod of the first electric push rod 44 is provided with a cleaning blade 45 with a length equal to the width of the primary filter screen 22. When the first electric push rod 44 is extended to its longest length, the bottom surface of the cleaning blade 45 abuts against the top surface of the primary filter screen 22, ensuring that there are no dead corners in the cleaning process, thereby improving the cleaning quality.

[0039] In this embodiment, the collection component 6 includes a dirt shield 61 with an opening on one side of the top. The opening of the dirt shield 61 faces and covers the drain outlet 13. The bottom surface of the dirt shield 61 is connected to a collection pipe 62. The lower end of the collection pipe 62 is connected to a collection box 63. An exhaust fan 64 is embedded in the middle of the wall opposite the drain outlet 13. When pollutants are collected at the drain outlet 13, they fall from the drain outlet 13 into the collection pipe 62 under the action of the exhaust fan 64, and then fall into the collection box 63 for periodic cleaning.

[0040] It should be further explained that an isolation net 65 is centrally located on the side of the exhaust fan 64 closest to the drain outlet 13. The vertical area of ​​the isolation net 65 is larger than the vertical cross-sectional area of ​​the exhaust fan 64. The isolation net 65 can effectively prevent flaky pollutants from covering the exhaust outlet of the exhaust fan 64, thereby affecting the normal operation of the exhaust fan 64. A cleaning scraper 67 is provided on the vertical wall of the isolation net 65 away from the exhaust fan 64, which is always in contact with it. The top of the cleaning scraper 67 is connected to the top surface of the dirt cover 61 through the second electric push rod 66. Under the action of the second electric push rod 66, the cleaning scraper 67 can effectively scrape away the pollutants attached to the surface of the isolation net, further ensuring the normal operation of the exhaust fan 64.

[0041] Finally, it should be noted that the first motor 31, the second motor 41, the first electric push rod 44, and the second electric push rod 66 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0042] Working Principle: In this embodiment, when in use, the polluted water source is fed into the filter box body 11 through the inlet pipe 15. The water flows through the primary filter assembly 2, where the larger pollutants in the water source are filtered out by the primary filter screen 22, thus completing the initial filtration. Afterward, the water source falls into the activated carbon tank 36, where harmful microorganisms, organic pollutants, and heavy metal ions in the water source are all filtered out by the activated carbon, thus completing the entire water pollution treatment process. The purified water source is then transported to the required locations through the outlet pipe 16. When the pollutants on the primary filter screen 22 accumulate to a certain amount, the cleaning blade 45 is adjusted to a height away from the primary filter screen 22 by the first electric push rod 44. Then, the second motor 41 is turned on to move the cleaning blade 45 to the end of the primary filter screen 22 near the inlet pipe 15. Afterward, the second motor 41 is turned off. Next, the first electric actuator 44 is used to adjust the cleaning blade 45 to contact the primary filter screen 22. The second motor 41 is then turned on again, causing the cleaning blade 45 to slide towards the drain outlet 13 to begin cleaning. Immediately afterwards, the exhaust fan 64 is turned on, and the pollutants that are continuously approaching the drain outlet 13 are smoothly collected and fall into the collection box 63 under the action of the exhaust fan 64, thus completing the cleaning work. In addition, when the activated carbon needs to be replaced, the first motor 31 is turned on. The first motor 31 drives the active bevel gear shaft 32 to rotate, which drives the driven bevel gear shaft 33. The driven bevel gear shaft 33 rotates the vertical screw 34, which drives the sliding cross support plate 35 to slide, thereby moving the activated carbon tank 36 upward. When the activated carbon tank 36 moves to the highest position, the primary filter screen 22 is removed and taken out, and then the activated carbon is replaced.

[0043] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
