Description

Technical Field

[0001] The present application relates to the technical field of river water purification and treatment, and in particular to an urban river purification and treatment system. Background Art

[0002] Urban river water purification has several main functions. First, it improves water quality and reduces the content of harmful substances in water, such as heavy metals, chemical oxygen demand (COD), biochemical oxygen demand (BOD) and other indicators, making river water clear, reducing odor, and improving the quality of urban water environment. Second, it protects aquatic organisms and provides a suitable living environment for aquatic animals such as fish and shellfish and aquatic plants, which helps maintain the diversity of aquatic organisms and promotes the balance of the ecosystem. Third, it beautifies the urban landscape. Clean river water can enhance the overall image of the city, provide urban residents with more ornamental waterfront space, and enhance the attractiveness of the city. Fourth, it protects public health. Purified water reduces pathogens and harmful chemicals, reduces the risk of residents contracting diseases due to contact with polluted water, and is of great significance to public health and safety. At present, a Chinese patent with the announcement number "CN213231931U" discloses an auxiliary purification device for urban river water, which includes a cylindrical box body and a feed inlet. A rotating motor is provided in the middle of the top of the cylindrical box body, a stirring shaft is welded at the bottom end of the output shaft of the rotating motor, a fixing frame is welded at the end of the side surface of the stirring shaft, and a horizontally placed crushing roller is symmetrically welded in the middle of the side surface of the stirring shaft. Both ends of the crushing roller are fixedly connected to the inner wall of the fixing frame. Blades distributed evenly are arranged on the crushing roller along the length direction, a scraper is fixed on the outer surface of the fixing frame, and brushes distributed evenly are fixed on the outer surface of the scraper at equal distances; a crushing roller with a blade is provided to facilitate crushing large particles of impurities in sewage and increase purification efficiency; a scraper with a brush is provided to facilitate the scraper to repeatedly scrape off large particles of impurities adhering to the inner wall of the cylindrical box through rotation, thereby increasing purification efficiency and preventing the inner wall of the cylindrical box from adhering to too many impurities to cause corrosion and shorten the service life of the device; During actual use, although the above-mentioned equipment has a certain filtering function and is provided with a scraper to assist in cleaning, there are still obvious defects and shortcomings in the specific use process. On the one hand, although the scraper can scrape off some impurities, the scraped impurities will still adhere to the inside of the device. During use, since the filter and other structures inside the equipment are not convenient for quick disassembly and assembly for cleaning and maintenance, it is usually necessary to open the equipment regularly for cleaning. On the other hand, each time cleaning is performed, the operation of the equipment must be stopped, and then the equipment must be opened for cleaning and maintenance. However, such operation is generally time-consuming and labor-intensive, which greatly affects the efficiency of the equipment in treating sewage. It can be seen that the equipment has certain defects and shortcomings under the current design, and it is urgently needed to improve the design to improve its efficiency and practicality in sewage treatment.

[0014] In summary, this application includes the following beneficial technical effects: The filtering mechanism of this equipment allows the sewage inlet pipe to be closely connected with the external sewage supply pipe through the connecting flange during use, ensuring that the sewage can flow smoothly into the filter box. At the same time, the drain pipe is also connected to the external sewage pipe with the help of the connecting flange, providing a discharge channel for the treated sewage. This connection method is not only convenient and fast, but also can effectively introduce sewage into the filter box for purification. During use, sewage continuously enters the filter box along the sewage inlet pipe, laying the foundation for the subsequent filtering and purification process. The filter begins to play an important role at this stage. It is like a barrier that blocks impurities in the sewage and provides preliminary guarantees for the subsequent treatment steps; The cleaning function in the filter mechanism is extremely efficient. When sewage enters the filter box, the filter begins to filter out impurities. At this time, the electric push rod is started to push the pull-out rack for linear displacement. Since the rack is meshed with the gear, the movement of the rack drives the gear to rotate, which in turn drives the shaft to rotate. The rotation of the shaft drives the base frame to rotate. The brush plate on the base frame rotates in contact with the filter in this process. At the same time, the telescopic spring continuously pushes the brush plate close to the filter to ensure the cleaning effect. In this way, when the shaft rotates, it can drive the brush plate to efficiently brush and clean the outer surface of the filter. This cleaning method can completely remove sewage impurities on the outer surface of the filter, effectively avoiding the phenomenon of filter clogging and improving sewage treatment efficiency. The waste residue discharge mechanism brings many advantages to the equipment. When the sewage enters the filter box, it is first filtered through the filter screen to effectively filter out the large particles of impurities in the sewage. Then, the electric push rod pushes the rack to make the rack cooperate with the gear, and then drives the elastic brush to rotate. The rotation of the elastic brush cleans the impurities on the filter screen to prevent the impurities from adhering to the outer surface of the filter screen. The cleaned impurities will fall into the discharge hopper. When these impurities need to be discharged, the drive motor is started to drive the auger inside the discharge pipe to rotate, and the discharge solenoid valve is opened to open the output end of the discharge pipe, so that the filtered dirt can be quickly discharged. This design makes it unnecessary to open the filter box and remove the filter screen when the equipment needs to be cleaned, and it has a powerful function of automatically cleaning the filter screen. The limiting mechanism greatly facilitates the disassembly and assembly of the filter. When the filter needs to be replaced, the bridge handrail is pulled down, and this action will synchronously pull the two linkage rods to rotate downward, and the linkage rod, the bridge handrail and the articulated wheel transmit each other, so that the slider inside the guide rail frame moves inward, and the inward movement of the slider will squeeze the telescopic spring to contract, thereby driving the limit block to disengage from the limit groove. At this time, the bottom of the limit arm loses the limit, and the sealing cover can be pulled out from the inside of the movable groove, so that the filter can be removed and cleaned conveniently and quickly. When installing the filter, it is inserted into the movable groove, and the sealing plate will cover the top of the movable groove for sealing. The limiting arm squeezes the guide inclined surface on the top of the limit block, so that the limit block compresses the spring, and when the limit groove of the limit arm contacts the limit block, the telescopic spring resets and pushes the limit block to be inserted into the limit groove for engagement, so that the sealing cover is stably installed on the top of the movable groove. This design is convenient and fast, and saves the time for overhauling and cleaning the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present application embodiment discloses a system for purifying and treating an urban river. Figure 1-9 As shown, it includes a base plate 1 and a sewage pipe 2, support legs 8 are fixedly installed at the four corners of the top of the base plate 1, a top seat 4 is fixedly installed on the top of the support legs 8, a filter box 5 is fixedly installed on the top of the top seat 4, movable slots 12 are opened on both sides of the top of the filter box 5, and a filter mechanism 6 is movably connected inside the movable slot 12, a waste residue discharge mechanism 3 is fixedly installed in the middle of the bottom of the filter box 5, drainage pipes 11 are fixedly installed at the output ends of both sides of the filter box 5, the sewage pipe 2 is fixedly installed between the inner sides of the drainage pipe 11, a sewage inlet pipe 10 is fixedly installed on the top of the filter box 5, and a limiting mechanism 9 is fixedly installed on one side of the filter box 5, and the limiting mechanism 9 is used to limit the installation of the filtering mechanism 6; The filter mechanism 6 includes a sealing cover 61, which covers and seals the top of the movable slot 12.

The sealing cover 61 can tightly cover and seal the top of the movable slot 12. This design greatly ensures the good sealing performance of the filter box 5. During the operation of the system, the sealing cover 61 can effectively prevent unfiltered sewage from leaking from the movable slot 12, thereby ensuring the rigor and reliability of the entire purification process. The limiting arm 62 is clamped with the limiting mechanism 9. This connection method enables the filter mechanism 6 to be stably installed in the filter box 5 during operation.

[0022] Please refer to Figure 1-Figure 6The limiting mechanism 9 includes a limiting groove 91 and a guide rail frame 92. The guide rail frame 92 is fixedly installed in the middle of the front of the filter box 5. The limiting groove 91 is opened at the inner lower end of the limiting arm 62. Both ends of the inner part of the guide rail frame 92 are fixedly connected with a telescopic spring 93. The outer end of the telescopic spring 93 is fixedly connected with a slider 94. The outer side of the slider 94 is fixedly connected with a limiting block 95. The outer end of the limiting block 95 is inserted into the inner side of the limiting groove 91 on the limiting arm 62. The front side of the slider 94 is rotatably connected with an articulated wheel 96. A linkage rod 97 is fixedly connected to the inner side of the connecting wheel 96, and a bridge handrail 98 is rotatably connected to the front side of the linkage rod 97. The two ends of the bridge handrail 98 are rotatably connected to the inner ends of the front sides of the two linkage rods 97, respectively. The front side of the limiting groove 91 is square in shape, and a guide slope 99 is provided at the upper end of the outer side of the limiting block 95. The guide rail frame 92 is fixed to the middle of the front side of the filter box 5 as an installation basis. The limiting groove 91 is at the lower end of the inner side of the limiting arm 62, and cooperates with the limiting block 95 to limit the filter mechanism 6. The telescopic spring 93 in the guide rail frame 92 provides elastic restoring force for the slider 94, ensuring that the limit block 95 is stably connected to the limit groove 91, thereby limiting the position of the limit arm 62 and ensuring the stability of the filter mechanism 6 in the box. The articulated wheel 96 on the slider 94 forms a linkage system with the linkage rod 97 and the bridge handrail 98. When the filter screen 63 needs to be disassembled, the bridge handrail 98 can be pulled out to drive the linkage rod 97 to rotate, so that the slider 94 moves in the guide rail frame 92, and the limit block 95 is separated from the limit groove 91, realizing convenience. During disassembly, the square shape of the limit groove 91 makes the connection more stable and not prone to shaking or misalignment. During installation, the guide slope 99 on the outside of the limit block 95 is squeezed by the limit arm 62 to cause the limit block 95 to compress the spring, and the limit arm 62 moves down smoothly. After contact, the spring resets and pushes the limit block 95 into the limit groove 91 to achieve automatic connection, thereby improving the convenience of installation. Overall, the limit mechanism 9 not only ensures the stability of the filter mechanism 6, but also facilitates the disassembly, assembly and replacement of the filter screen 63, thereby improving the practicality and reliability of the system.

[0023] The implementation principle of an urban river purification treatment system in an embodiment of the present application is as follows: during actual use of the device, by setting a filtering mechanism 6, when performing filtering and purification operations, the sewage inlet pipe 10 can be connected to an external sewage supply pipe with the help of a connecting flange 13, and the drain pipe 11 can also be connected to an external sewage discharge pipe 2 through the connecting flange 13. During use, sewage will smoothly enter the filter box 5 through the sewage inlet pipe 10. At this time, the filter screen 63 begins to play its important role and assists in filtering impurities in the sewage. During the filtering process of the filter screen 63, the electric push rod 641 can also be started. The electric push rod 641 will push the pull-out rack 643 to perform linear displacement. Since the rack 643 is meshed with the gear 644, the linear displacement of the rack 643 will further drive the gear 644 to rotate. At this time, the rack 643 drives the gear 644 to rotate. The gear 644 drives the shaft 642 to rotate. The shaft 642 rotates and drives the base frame 6451 to rotate. When the base frame 6451 rotates, the brush plate 6453 is driven to rotate against the filter screen 63. In addition, the telescopic spring 93 continuously pushes the brush plate 6453 to closely contact the filter screen 63. In this way, the rotation of the shaft 642 can drive the brush plate 6453 to efficiently brush and clean the outer surface of the filter screen 63. Overall, this design has an extremely efficient cleaning effect and can thoroughly brush and clean the sewage impurities on the outer surface of the filter screen 63, effectively avoiding the filter screen 63 from being blocked. It can automatically brush and clean the outer surface of the filter screen 63, greatly avoiding the filter screen 63 from being blocked by dirt, and can significantly improve the overall efficiency of the sewage treatment device, while also avoiding the undesirable phenomenon of sewage blockage. By setting up the waste residue discharge mechanism 3, during the use of the device, when the sewage enters the filter box 5, the sewage will be filtered through the filter screen 63, and the filter screen 63 can effectively filter out large particles of impurities in the sewage. At this time, the electric push rod 641 pushes the rack 643, so that the rack 643 cooperates with the gear 644, and then drives the elastic brush 645 to rotate. After the elastic brush 645 rotates, the impurities on the filter screen 63 can be brushed and cleaned, avoiding the situation that the impurities are attached to the outer surface of the filter screen 63, and the impurities cleaned by the brush can smoothly fall into the interior of the discharge hopper 31, and when it is needed to be discharged When the impurities cleaned by it are discharged, the driving motor 35 can be started to drive the auger 34 inside the discharge pipe 32 to rotate. At the same time, the discharge solenoid valve 33 is opened to open the output end of the discharge pipe 32, so that the filtered dirt can be quickly discharged. It can be seen that the device does not need to open the filter box 5 or remove the filter screen when it needs to be cleaned. It has a powerful function of automatically cleaning the filter screen. At the same time, the whole can quickly discharge the filtered dirt, has good anti-blocking performance, and the overall filtration efficiency is relatively high. It is also more convenient to clean and remove dust and impurities. It is convenient and quick to clean and can be quickly put into use, which can greatly improve the overall sewage treatment efficiency of the device; By setting the limiting mechanism 9, during the use of the device, if the filter screen 63 needs to be disassembled and replaced, the bridge handrail 98 can be pulled down. While the bridge handrail 98 moves down, the two linkage rods 97 can be synchronously pulled to rotate toward the downward position. The linkage rod 97, the bridge handrail 98 and the articulated wheel 96 transmit each other. At this time, the slider 94 inside the guide rail frame 92 can be pulled inward synchronously. The inward movement of the slider 94 will squeeze the telescopic spring 93 to contract. At this time, the telescopic spring 93 contracts and the slider 94 moves inward, which can drive the limiting block 95 to disengage from the limiting groove 91. After the limiting block 95 and the limiting groove 91 are separated from each other, the bottom of the limiting arm 62 loses its limit, and then the sealing cover 61 can be pulled out from the inside of the movable slot 12, so that the filter screen 63 can be removed and cleaned from the inside of the movable slot 12 conveniently and quickly. During its use, if it needs to be installed, the filter screen 63 can be inserted into the inside of the movable slot 12. At this time, the sealing plate will cover the movable slot 12. The top of the notch 12 is sealed against the top of the movable notch 12. At this time, the limit arm 62 will squeeze the guide inclined surface 99 at the top of the limit block 95. The guide inclined surface 99 is used for guidance, which can cause the limit block 95 to squeeze the telescopic spring 93 to contract. The limit spring 6452 contracts inside the guide rail frame 92. At this time, the limit arm 62 can move downward. When the limit groove 91 of the limit arm 62 contacts the limit block 95, the telescopic spring 93 is reset to push the limit block 95 to be inserted into the inner side of the limit groove 91. The limit block 95 and the limit groove 91 are mutually engaged, and the sealing cover 61 can be stably engaged and installed and covered on the top of the movable groove. It can be seen that the device not only has the function of automatic cleaning and impurity discharge, but also is convenient for quick disassembly and assembly when the filter screen 63 needs to be cleaned. The overall use is relatively convenient, which can save the time for maintenance and cleaning of the filter screen 63, and can significantly improve the overall efficiency of the equipment for sewage treatment, which is convenient for the use of the device.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
