[0001] This utility model relates to the field of water pollution prevention and control technology, specifically to an integrated filter tank for groundwater pollution prevention and control. Background Technology

[0002] Water pollution prevention and control refers to the prevention and treatment of water pollution caused by the introduction of certain substances, which alter the chemical, physical, biological, or radioactive properties of water bodies, thereby affecting the effective use of water, endangering human health, or damaging the ecological environment, and resulting in water quality deterioration. To reduce water pollution, filter tanks are often used to filter wastewater.

[0003] Groundwater pollution control is an important issue in the current environmental protection field. Traditional groundwater filtration equipment suffers from problems such as low filtration efficiency, easy clogging, and high maintenance costs, making it difficult to meet the needs of efficient and environmentally friendly groundwater treatment. During the filtration process, impurities will adhere to the filter plate, causing the filter holes to become clogged and affecting the filtration efficiency. To address this, we propose an integrated filter tank for groundwater pollution control. Utility Model Content

[0027] 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.

[0028] like Figures 1-8 As shown, this utility model provides a technical solution: an integrated filter tank for groundwater pollution prevention and control, including a filter tank body 1, a dirt removal component 2, and a filter component 3. Under the joint action of each part, groundwater can be filtered and impurities in the filter tank body 1 can be treated. By setting the dirt removal component 2, impurities generated during groundwater filtration can be treated and attached impurities can be scraped off. The dirt removal component 2 is set inside the filter tank body 1. By setting the filter component 3, underground sewage can be filtered, thereby filtering harmful substances such as suspended solids, organic matter, and heavy metal ions in the groundwater. The filter component 3 is set outside the dirt removal component 2.

[0029] like Figure 1-8As shown in the embodiment of this application, a guide bucket 202 is located at the top of the inner wall of the filter tank 1. A fixed plate 203 is provided at the bottom of the guide bucket 202. A fixed ring 204 is provided on the outer wall of the fixed plate 203. The fixed ring 204 rotates in an annular groove on the inner wall of the filter tank 1. Multiple fan blades 207 are provided at the bottom of the fixed plate 203. Scrapers 210 are provided on both sides of the fan blades 207. A support base 205 is provided at the bottom of the fan blades 207. A fixed shaft 201 is provided at the middle of the top of the support base 205. The top of the fixed shaft 201 extends to the outer surface of the filter tank 1. An annular sleeve 212 and a fixed sleeve 209 are respectively provided on the outer wall of the fixed shaft 201. Multiple round rods 213 are provided on the outer wall of the annular sleeve 212. One end of the round rod 213 is connected to the fixed plate 203. The outer wall of the fixed sleeve 209 is provided with multiple stirring blades 208. The inner side of the support base 205 is provided with a cavity, and a push rod 206 is provided in the cavity. The piston end of the push rod 206 is connected to a meniscus 211. Specifically, when filtering underground sewage, the filtered impurities need to be discharged, and some impurities will adhere to the surface of the filter cylinder 305 and the coarse filter layer 304 during the filtration process. Therefore, they need to be scraped off using a scraper 210. When filtering underground sewage, the underground sewage is first injected into the filter tank 1 through the inlet 102. When the underground sewage enters the filter tank 1, it falls onto the guide bucket 202 and is guided by the guide bucket 202 to enter the inner side of the filter cylinder 305 for filtration. The guide bucket 202 is fixedly installed in the filter tank. The inner wall of the filter tank 1 is rotated by a motor 101 driving a fixed shaft 201. During rotation, the fixed shaft 201 drives the annular sleeve 212 and the fixed sleeve 209 to rotate. A fixed disc 203 is connected to the outer wall of the annular sleeve 212 via a round rod 213. A fixed ring 204 is provided on the outer wall of the fixed disc 203, rotating within an annular groove on the inner wall of the filter tank 1. The fixed ring 204 limits the movement of the fixed disc 203. The rotation of the annular sleeve 212 drives the fixed disc 203 to rotate, which in turn drives the fan blade 207 to rotate. Scrapers 210 are provided on both sides of the fan blade 207. The rotation of the fan blade 207 drives the scrapers 210 to rotate synchronously, allowing the scrapers 210 to rotate and clean the filter cartridge. Impurities on the outer wall of filter cylinder 305 and the inner wall of coarse filter layer 304 are scraped off. The fan blade 207 has round holes to facilitate groundwater flow. The scraped impurities fall onto the support base 205, which has a slight inward slope to allow the impurities scraped off by scraper 210 to flow into filter cylinder 305. The sieve holes on filter cylinder 305 are larger than those on coarse filter layer 304, thus effectively scraping impurities from both filter cylinder 305 and coarse filter layer 304. During the rotation of fixed shaft 201, fixed sleeve 209 rotates synchronously, which in turn rotates stirring blade 208. Stirring blade 208 also has round holes to facilitate groundwater flow, and one side of stirring blade 208 rests against the inner wall of filter cylinder 305.During the rotation of the stirring blade 208, the groundwater undergoes centrifugal motion within the filter cylinder 305, simultaneously scraping away impurities adhering to the inner wall of the filter cylinder 305. The scraped impurities fall onto the meniscus 211, which is then contracted by the push rod 206, exposing the meniscus groove on the support base 205. The impurities pass through this groove and fall into the guide hopper 106. The guide hopper 106 then directs the impurities out through the drain outlet 104. The filtered water is discharged through the drain outlet 103. Both the drain outlet 103 and the drain outlet 104 are controlled by the control valve 105, enabling the filtration of underground wastewater and the discharge of impurities produced after filtration.

[0030] like Figure 1-8 As shown in the embodiment of this application, a fixing frame 302 is located at the top of the support base 205. Inside the fixing frame 302, from the outside in, an activated carbon layer 301, a fine filter layer 303, and a coarse filter layer 304 are sequentially arranged. Its top is connected to the bottom of the fixing plate 203 via another fixing frame 302. A filter cylinder 305 is arranged between the fixing plate 203 and the support base 205. Specifically, when filtering underground sewage, multi-stage filtration can efficiently remove impurities and harmful substances by sequentially arranging the activated carbon layer 301, fine filter layer 303, and coarse filter layer... 304 is capable of multi-stage filtration of groundwater. The filter cartridge 305 is the first line of defense in multi-stage filtration, isolating solid impurities within the filter cartridge 305. The coarse filter layer 304 is mainly used to remove tiny suspended particles in groundwater. The fine filter layer 303 is used to filter microorganisms in groundwater. The activated carbon layer 301 is used to adsorb organic matter. The activated carbon layer 301, the fine filter layer 303, and the coarse filter layer 304 are equipped with fixing frames 302 at both ends and are installed in the filter tank 1 through the fixing frames 302, thereby ensuring the safety of groundwater quality.

[0031] like Figure 1-8 As shown in the embodiment of this application, a motor 101 is provided at the top center of the filter tank 1, and a fixed shaft 201 is connected to the output end of the motor 101. A water inlet 102 is provided at the top of the filter tank 1, a sludge guide hopper 106 is provided at the bottom of the filter tank 1, and a sludge discharge port 104 is provided at the bottom of the sludge guide hopper 106. A drain outlet 103 is provided on the outer wall of the filter tank 1. Both the drain outlet 103 and the sludge discharge port 104 are connected to a control valve 105. Specifically, in the filtration of underground sewage, underground sewage is injected through the water inlet 102, and the underground sewage is discharged through the drain outlet 103 after filtration. The filtered impurities are discharged through the sludge discharge port 104. Both the sludge discharge port 104 and the drain outlet 103 are controlled by the control valve 105. The motor 101 is used to provide power for the filter tank 1 to filter sewage. The motor 101 in this application is connected to an external power supply and controlled by a control system.
