Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a wastewater purification and recycling device for rural development. Background Technology

[0002] In rural areas, with the improvement of living standards and the development of agricultural production, the amount of sewage discharge is increasing day by day. Sewage purification and recycling devices are facilities used to treat rural domestic sewage, livestock wastewater and some agricultural production wastewater. They aim to remove pollutants from sewage through a reasonable treatment process, so that the treated sewage meets certain water quality standards, thereby realizing the recycling of water resources, reducing dependence on fresh water resources, and reducing the pollution and damage to the rural ecological environment caused by direct sewage discharge.

[0003] Existing rural wastewater treatment devices, through conventional steps such as sedimentation, filtration, and biodegradation, to some extent avoid direct pollution of the surrounding environment and achieve partial water resource recycling. However, these devices often have a relatively simple wastewater pretreatment stage. Due to the varying sizes of impurities in the wastewater, the core components of subsequent higher-precision ultrafiltration and reverse osmosis processes, which use membrane modules with extremely small pore sizes to deeply remove dissolved organic matter, heavy metal ions, and other minute pollutants, can lead to larger impurities that are not effectively removed in the early stages. These larger impurities can deposit and accumulate on the membrane surface when entering the high-precision purification stage, causing equipment blockage. Once blockage occurs, frequent shutdowns for cleaning and maintenance are required, increasing operating costs and manpower. Furthermore, it reduces the overall purification efficiency of the device, affecting the stable production and supply of reclaimed water and failing to fully meet the diverse water needs of rural areas. This limits the promotion and efficient operation of wastewater purification and recycling devices in rural areas. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a rural wastewater purification and recycling device, comprising a base plate 1, a filter box 2 fixedly connected to the top of the base plate 1, an inlet pipe 3 connected to the top left side of the filter box 2, a guide pipe 4 connected to the right side of the filter box 2, a large impurity filtration mechanism 5 provided inside the filter box 2, the large impurity filtration mechanism 5 being used to collect larger impurities in the wastewater, and an impurity sedimentation and cleaning mechanism 6 provided inside the right side of the filter box 2, the impurity sedimentation and cleaning mechanism 6 being used to perform multiple sedimentation and filtration of the wastewater flowing into the filter box 2;

[0033] The large impurity filtration mechanism 5 includes two fixed plates 501. Two T-shaped grooves 502 are opened on each adjacent side of the two fixed plates 501. A collection box 503 is arranged between the two fixed plates 501. Two T-shaped slide rails 504 are fixedly connected to the front and rear sides of the collection box 503. Multiple T-shaped slide rails 504 are slidably connected inside multiple T-shaped grooves 502. Multiple filter holes 505 are equidistantly opened on the upper right side of the collection box 503. A sealing cover plate 506 is rotatably connected to the front end of the top of the collection box 503. Two fastening grooves 507 are opened at the rear end of the top of the collection box 503. Fastening bolts 508 are rotatably connected to the left and right ends of the rear top side of the sealing cover plate 506. The ends of the two fastening bolts 508 are threaded into the inside of the two fastening grooves 507 respectively.

[0034] Specifically, wastewater first enters the filter box 2 through the inlet pipe 3. When the wastewater flows in, since the collection box 503 is located on the wastewater flow path, the wastewater first enters the collection box 503 and slides within the T-shaped groove 502 of the fixed plate 501 via the T-shaped slide rails 504 on its front and rear sides, thus securing it firmly in the filter box 2. Larger impurities in the wastewater are blocked by the collection box 503 and remain inside the collection box 503. As the wastewater continues to flow in, smaller impurities and wastewater flow through multiple filter holes 505 equidistantly opened on the upper right side of the collection box 503 to the impurity sedimentation and cleaning mechanism 6 on the right side of the collection box 503. When large impurities accumulate to a certain extent in the collection box 503, they need to be cleaned. At this time, the fastening bolts 508 on the left and right ends of the top rear side of the sealing cover 506 are first removed from the fastening mechanism. Unscrew the cover plate 506 from the groove 507 and then rotate it to open it. This allows for easy cleaning of large impurities inside the collection box 503. After cleaning, reset the cover plate 506 and seal it by connecting it to the groove 507 with the fastening bolt 508. This restores the collection box 503 to its normal filtration state, effectively separating larger impurities from the wastewater in advance, preventing them from clogging or damaging subsequent wastewater purification equipment. This ensures the stable operation of the entire wastewater purification and recycling device. Furthermore, the easy disassembly and cleaning of the collection box 503 makes daily maintenance more convenient and efficient. This facilitates the long-term and stable use of the device for wastewater purification and recycling in rural areas, reducing wastewater pollution in the rural environment and improving water resource utilization.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The impurity sedimentation and cleaning mechanism 6 includes multiple partitions 601. Multiple filter pools 602 are arranged on the right side of the inside of the filter box 2. The multiple partitions 601 are respectively arranged between the adjacent filter pools 602. Two inclined plates 603 are fixedly connected to the inner top wall of the filter box 2. The two inclined plates 603 are respectively located at the top of the two middle filter pools 602. Multiple sludge discharge pipes 604 are equidistantly connected to the bottom front side of the filter box 2. The rear ends of the multiple sludge discharge pipes 604 all pass through the front side of the filter box 2 and are respectively connected to the inside of the multiple filter pools 602. Sludge discharge valves 605 are fixedly installed on the top of the multiple sludge discharge pipes 604.

[0036] Specifically, after the wastewater undergoes preliminary filtration by the large impurity filtration mechanism 5, it flows into the right side of the filter box 2. The wastewater first flows into the first filter tank 602. As the water flow slows down upon entering the filter tank 602, some impurities in the wastewater begin to settle to the bottom of the filter tank 602 under gravity. Multiple baffles 601 divide the right side of the filter box 2 into multiple filter tanks 602. The wastewater flows through these filter tanks 602 sequentially. With each filter tank 602, the flow velocity further decreases, and the sedimentation effect gradually increases, allowing the impurities in the wastewater to settle more thoroughly. Two inclined plates 603 located on the inner top wall of the filter box 2, at the top of the two middle filter tanks 602, guide the incoming wastewater and prevent it from directly impacting the already settled impurities at the bottom of the tank, preventing them from rising again. As the wastewater settles in each filter tank 602... As the process continues, impurities accumulate at the bottom of the tank. When it is necessary to clean the settled impurities, the sludge discharge valve 605 at the top of the sludge discharge pipe 604 can be opened. Since multiple sludge discharge pipes 604 are equidistantly connected to the bottom front side of the filter box 2 and their rear ends are respectively connected to the inside of multiple filter pools 602, under the action of gravity and water pressure, the sludge settled at the bottom of the filter pool 602 will be discharged from the filter box 2 through the sludge discharge pipe 604. By reasonably controlling the opening and closing degree and sludge discharge time of the sludge discharge valve 605, the settled impurities in each filter pool 602 can be effectively cleaned, ensuring the continuous and efficient operation of the impurity sedimentation and cleaning mechanism 6. Through multiple sedimentation and filtration, impurities in the sewage can be further removed, laying a good foundation for subsequent more refined sewage purification treatment. This helps to improve the purification effect of the entire sewage purification and recycling device, enabling the treated sewage to better meet the requirements of recycling.

[0037] Reference Figure 1 , Figure 2 and Figure 5 A bubble brick 509 is placed in the center of the filter box 2, and the left side of the bubble brick 509 is attached to the right side of the collection box 503. A viewing plate 7 is fixedly installed on the front right side of the filter box 2, and a scale line 8 is fixedly connected to the front right side of the viewing plate 7. A connecting pipe 9 is connected to the front right side of the filter box 2, and the input end of the connecting pipe 9 is connected to the inside of the right filter pool 602. A water quality tester 10 is connected to the top of the connecting pipe 9. A display 11 is fixedly connected to the rear side of the water quality tester 10, and the display 11 is electrically connected to the water quality tester 10. Fixed feet 12 are fixedly connected to the four corners of the bottom of the base plate 1, and the bottom of the multiple fixed feet 12 is designed to be non-slip. A diversion pipe 13 is connected to the output end of the guide pipe 4, and a switch valve 14 is fixedly installed on both output ends of the diversion pipe 13 and the input end of the inlet pipe 3.

[0038] Specifically, the bubble brick 509 is located in the center of the filter box 2 and is attached to the right side of the collection box 503, which can further prevent larger impurities from entering the subsequent stages. The transparent plate 7 is installed on the front right side of the filter box 2 and has scale lines 8, which makes it convenient to observe the changes in the sewage level and turbidity in the filter box 2, so as to grasp the operating status of the device and perform corresponding operations in a timely manner. The connecting pipe 9 connects the right-end filter tank 602 to the water quality tester 10. The water quality tester 10 can detect the acidity, alkalinity, oxygen content and turbidity of the sewage flowing out of the filter tank 602 in real time, and clearly display the data through the display 11 electrically connected to it on the rear side, providing a basis for judging the degree of sewage purification. The fixing pads 12 at the four corners of the bottom of the base plate 1 are designed with anti-slip to ensure the stability of the device when placed and prevent displacement due to slippery ground or other external factors. The diversion pipe 13 connected to the output end of the guide pipe 4 and the switch valve 14 installed at the input end of the inlet pipe 3 can switch the flow direction of sewage diversion, recycling or discharge by controlling the opening and closing of the valve.

[0039] Working principle: Wastewater first enters the filter box 2 through the inlet pipe 3. When the wastewater flows in, since the collection box 503 is located on the wastewater flow path, the wastewater first enters the collection box 503 and slides within the T-shaped groove 502 of the fixed plate 501 via the T-shaped slide rails 504 on its front and rear sides, thus being stably positioned in the filter box 2. Larger impurities in the wastewater are blocked by the collection box 503 and remain inside the collection box 503. As the wastewater continues to flow in, smaller impurities and wastewater flow through multiple equidistant filter holes 505 on the upper right side of the collection box 503 to the impurity sedimentation and cleaning mechanism 6 on the right side of the collection box 503. When large impurities accumulate to a certain extent in the collection box 503, they need to be cleaned. At this time, first unscrew the fastening bolts 508 on the left and right ends of the top rear side of the sealing cover 506 from the fastening groove 507, then rotate the sealing cover 506 to open it, so that the large impurities in the collection box 503 can be easily cleaned. After cleaning, reset the sealing cover 506 and seal it by connecting the fastening bolts 508 to the fastening groove 507 with threads, so that the collection box 503 can return to normal filtration working state, which can effectively separate larger impurities in sewage in advance and avoid them from clogging or damaging subsequent sewage purification equipment.

[0040] Furthermore, after the wastewater undergoes preliminary filtration by the large impurity filtration mechanism 5, it flows into the right side area of ​​the filter box 2. The wastewater first flows into the first filter pool 602. As the water flow velocity slows down upon entering the filter pool 602, some impurities in the wastewater begin to settle to the bottom of the filter pool 602 under gravity. Multiple baffles 601 divide the right side of the filter box 2 into multiple filter pools 602. The wastewater flows through these filter pools 602 sequentially. With each filter pool 602, the flow velocity further decreases, and the sedimentation effect gradually increases, allowing the impurities in the wastewater to settle more thoroughly. Two inclined plates 603 located on the inner top wall of the filter box 2, at the top of the two middle filter pools 602, can guide the incoming wastewater and also... It can prevent sewage from directly impacting the sedimented impurities at the bottom of the tank and prevent them from rising again. As the sedimentation process of sewage in each filter tank 602 continues, impurities accumulate at the bottom of the tank. When it is necessary to clean the sedimented impurities, the sludge discharge valve 605 at the top of the sludge discharge pipe 604 can be opened. Since multiple sludge discharge pipes 604 are equidistantly connected to the bottom of the front side of the filter box 2 and the rear ends are respectively connected to the inside of multiple filter tanks 602, under the action of gravity and water pressure, the sludge settled at the bottom of the filter tank 602 will be discharged from the filter box 2 through the sludge discharge pipe 604. By reasonably controlling the opening and closing degree of the sludge discharge valve 605 and the sludge discharge time, the sedimented impurities in each filter tank 602 can be effectively cleaned, ensuring the continuous and efficient operation of the impurity sedimentation and cleaning mechanism 6.
