Description

Technical Field

[0001] This utility model relates to the field of construction wastewater treatment technology, and more specifically, to a multi-stage sedimentation and purification device for industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products lost with the water, as well as pollutants generated during the production process. The composition of wastewater varies greatly among different industrial sectors. For example, chemical wastewater may contain heavy metals and organic matter, while papermaking wastewater contains large amounts of lignin and fiber. If discharged directly without treatment, it will cause serious harm to the environment and ecosystem.

[0003] Publication No. (CN219804332U) discloses a multi-stage wastewater sedimentation and purification device, including multi-stage sedimentation tanks, filter tanks, and a flow guide channel. The multi-stage sedimentation tanks include a primary sedimentation tank, a secondary sedimentation tank, a tertiary sedimentation tank, and a disinfection tank. The disinfection tank is connected to the outlet of the tertiary sedimentation tank. The filter tanks include filter tank one and filter tank two. Filter tank one is located near the upper sidewall of the secondary and tertiary sedimentation tanks, and filter tank two is located near the sidewall of the primary sedimentation tank near the secondary sedimentation tank. The flow guide channel is located between filter tank one and filter tank two, connecting the adjacent sidewalls of filter tank one and filter tank two. By setting up multi-stage sedimentation tanks and vertically distributed filter tanks, impurities can be effectively precipitated and filtered in the effluent, improving the sedimentation and separation efficiency of engineering wastewater. It efficiently separates suspended solids, sludge, and floating oil, improving wastewater quality through multiple filtrations and purifications, and ensuring that industrial wastewater does not affect subsequent soil conditions.

[0004] However, this multi-stage wastewater sedimentation and purification device has the following drawbacks: it cannot quickly adjust the flow rate of water entering different zones. Different stages of the wastewater sedimentation process require different flow rates. In the initial sedimentation stage, the flow rate needs to be relatively slow so that large particles can quickly settle to the bottom. The inability to quickly adjust the flow rate means that excessively fast flow rates will cause large particles to be carried to the next zone before they have fully settled, affecting the sedimentation effect and reducing the quality of wastewater purification. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-stage sedimentation and purification device for industrial wastewater, so as to solve the problem that the flow rate of internal water into different areas cannot be quickly adjusted in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-stage sedimentation and purification device for industrial wastewater, comprising...

[0007] The main body has two baffles movably connected to its inner wall. A button is slidably connected to the inner wall of each baffle. A guide plate is fixedly connected to the outside of each button. A movable plate one is coupled to the outside of each button. A connecting column is fixedly connected to the inner wall of movable plate one. A movable plate two is movably connected to the outside of the connecting column. A locking pin is movably connected to the inner wall of movable plate two. A top block is slidably connected to the inner wall of each baffle. An S-shaped elastic element is fixedly connected to the outside of the top block. Two guide sleeves are fixedly connected to the outside of each baffle. Springs are fixedly connected to the inner walls of both guide sleeves. A limit plate is fixedly connected to the bottom of each baffle. Multiple slots are provided on the inner wall of the main body. Two communication ports are initially located on the inner wall of the main body. Two filter plates are movably connected to the inner wall of the main body. A diversion assembly for diverting flow to subsequent components is fixedly connected to the inner wall of the main body.

[0008] The diversion assembly includes two fixed plates, which are externally fixedly connected to the inner wall of the main body. A diversion plate is fixedly connected to the outside of the fixed plates. Multiple water passage holes are opened on the outside of the fixed plates. A water injection hole is opened on the outside of the main body. A sewage discharge hole one is opened on the inner wall of the main body. A sewage discharge hole two is opened on the inner wall of the main body. A water outlet hole is opened on the outside of the main body.

[0009] The first movable plate is externally movably connected to the inner wall of the slot, and the second movable plate is externally movably connected to the inner wall of the slot.

[0010] The end of the spring away from the guide sleeve is fixedly connected to the inner wall of the main body, and the end of the limiting plate away from the water baffle is slidably connected to the inner wall of the main body.

[0011] The end of the S-shaped elastic element away from the top block is fixedly connected to the inner wall of the baffle plate, and the end of the top block away from the S-shaped elastic element is in contact with the outside of the movable plate.

[0012] The outer side of the first movable plate is in contact with the outer side of the top block, and the outer side of the first movable plate is in contact with the outer side of the second movable plate.

[0013] The two ends of the locking pin are fixedly connected to the inner wall of the baffle plate, and the outer side of the movable plate is movably connected to the inner wall of the baffle plate.

[0014] The movable plate 2 is externally movably connected to the inner wall of the baffle plate, and the button is externally slidably connected to the inner wall of the baffle plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the above scheme, sewage is discharged into the main body through the water injection hole. After sedimentation, the sewage passes through. Pressing the button in the baffle plate causes the button to move downwards under the guidance of the guide plate. The button then transmits force to movable plates one and two. Since movable plates one and two are connected by connecting columns, and two locking pins pass through movable plates one and two and connect them to the inside of the baffle plate, when the button presses down on movable plates one and two, they swing around their fixed locking pins as fulcrums, causing the connection between movable plates one and two to move downwards and apply pressure to the top block. At the same time, the top block squeezes the S-shaped elastic element. The S-shaped elastic element is compressed so that movable plates one and two are no longer locked in the slot inside the main body. At this point, the amount of water discharged from the main body can be determined by moving the baffle plate, avoiding the impact of water flowing into the next sedimentation tank before it has completely settled. Furthermore, the outflowing water is filtered by the filter plate behind it, improving water quality and working efficiency.

[0017] In the above scheme, by setting up a diversion component, when water flows into the interior of the main body from the water inlet, the excessive water flow will affect the sedimentation rate. Therefore, when the water flow is large, it will impact the diversion plate in the fixed plate. Since the diversion plate is triangular in shape, the water flow will be dispersed when it impacts the diversion plate, thus reducing the impact of the water flow. In addition, there are water passages on both sides of the diversion plate, so after the water flow is dispersed and the force decreases, it will enter the rear through the water passages for rapid sedimentation. After the sedimentation is completed, the wastewater with turbid impurities will be discharged through the drain hole, realizing a multi-stage sedimentation and purification effect and improving the recycling of water resources.

[0029] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] As attached Figure 1 To be continued Figure 9 An embodiment of this utility model provides a multi-stage sedimentation and purification device for industrial wastewater, including...

[0031] The main body 1 is the foundational structure of the entire sedimentation and purification device. Two baffles 2 are movably connected to the inner wall of the main body 1. These baffles 2 move within the main body 1, controlling the flow and discharge of water. Adjusting the position of the baffles 2 regulates the discharge volume, preventing water from flowing into the next sedimentation tank before complete sedimentation. Buttons 3 are slidably connected to the inner walls of both baffles 2. These buttons 3 slide within the baffles 2 and act as triggers for adjusting the baffles. Adjustment is achieved by pressing a button 3.

[0032] A guide plate 4 is fixedly connected to the outside of button 3. The guide plate 4 is fixed to the outside of button 3, and its main function is to guide the sliding of button 3, ensuring that button 3 can move in the correct direction. A movable plate 5 is externally coupled to button 3. Movable plate 5 is coupled to button 3. When button 3 is pressed and moves downwards, it transmits force to movable plate 5, causing movable plate 5 to move as well. A connecting post 6 is fixedly connected to the inner wall of movable plate 5. The connecting post 6 is fixed to the inner wall of movable plate 5 and connects movable plate 7 to movable plate 7, forming a relatively rotating connection structure between them, providing conditions for subsequent swinging movements. Movable plate 7 is movably connected to the outside of connecting post 6. Movable plate 7 is movably connected to movable plate 5 through connecting post 6. When movable plate 5 is subjected to the force of button 3, it will move through connecting post 6, causing movable plate 7 to swing at a certain angle around connecting post 6.

[0033] A locking pin 8 is movably connected to the inner wall of movable plate 2 7. The locking pin 8 is movably connected to the inner wall of movable plate 2 7, and its two ends are fixedly connected to the inner wall of baffle plate 2. It serves as the fulcrum for the swinging of movable plates 1 5 and 2 7, allowing them to swing around the locking pin 8 when subjected to force. A top block 9 is slidably connected to the inner wall of baffle plate 2. When movable plates 1 5 and 2 7 swing, their connection point moves downwards, applying pressure to the top block 9, thus triggering the movement. An S-shaped elastic element 10 is fixedly connected to the outside of the top block 9. When the top block 9 is subjected to pressure from movable plates 1 5 and 2 7, it compresses the S-shaped elastic element 10. The S-shaped elastic element 10, being elastic, undergoes compression deformation to allow movable plates 1 5 and 2 7 to leave the interior of the slot 14 in the main body 1 and cease engaging.

[0034] Two guide sleeves 11 are fixedly connected to the outside of the baffle plate 2. These guide sleeves 11 provide an installation position and guide for the spring 13, allowing the spring 13 to extend and retract along the direction of the guide sleeve 11. They also limit and guide the movement of the baffle plate 2. Springs 13 are fixedly connected to the inner walls of both guide sleeves 11. These springs 13 act as a buffer and reset mechanism when the baffle plate 2 moves. After the baffle plate 2 moves, the spring 13 provides a restoring force, helping the baffle plate 2 return to its initial position or remain in the adjusted position. The end of the spring 13 furthest from the guide sleeve 11 is fixedly connected to the inner wall of the main body 1. This connection allows the spring 13 to generate a force between the baffle plate 2 and the main body 1.

[0035] A limiting plate 12 is fixedly connected to the bottom of the baffle plate 2. The limiting plate 12 is fixed to the bottom of the baffle plate 2, and its function is to limit the range of movement of the baffle plate 2 on the inner wall of the main body 1, prevent the baffle plate 2 from moving excessively, and ensure that the movement of the baffle plate 2 is within a reasonable range. The end of the limiting plate 12 away from the baffle plate 2 is slidably connected to the inner wall of the main body 1. This connection method ensures that the limiting plate 12 can slide on the inner wall of the main body 1 as the baffle plate 2 moves. Multiple slots 14 are provided on the inner wall of the main body 1. The slots 14 are provided on the inner wall of the main body 1 for engaging with the movable plate 5 and the movable plate 7. When the movable plate 5 and the movable plate 7 are in their initial positions, their outer surfaces are engaged with the inner wall of the slots 14, which fixes the baffle plate 2 and keeps it in a stable position. The external movable plate 5 is movably connected to the inner wall of the slot 14, and the external movable plate 7 is movably connected to the inner wall of the slot 14. This connection relationship enables the engagement and disengagement of the movable plates 5 and 7 with the slot 14.

[0036] The inner wall of the main body 1 has two connecting openings 15. These openings allow purified water from different areas within the main body 1 to circulate, providing necessary channels for wastewater sedimentation and purification. Two filter plates 16 are movably connected to the inner wall of the main body 1. These filter plates 16 move within the inner wall of the main body 1, and their main function is to filter the water flowing out from the baffle plate 2, removing impurities and improving water quality. When water flows out from the baffle plate 2, it passes through the filter plates 16, which intercept impurities, allowing purified water to pass through. A flow-diverting assembly is fixedly connected to the inner wall of the main body 1. This assembly diverts the water flow entering the main body 1, preventing excessive water flow from affecting the sedimentation rate and improving the sedimentation and purification effect.

[0037] The diversion assembly includes two fixed plates 17, which are externally fixed to the inner wall of the main body 1. The fixed plates 17 provide a mounting base for the diversion plate 18, ensuring the stability of the diversion assembly. The diversion plate 18 is externally fixed to the fixed plates 17 and is triangular in shape. When water flows into the main body 1 from the water inlet 20, if the flow is too large, it will impact the diversion plate 18. Due to its triangular shape, the water flow is dispersed, reducing the impact force and allowing the water to enter the sedimentation area more smoothly. Multiple water passage holes 19 are provided on the outside of the fixed plates 17. After the water flow is dispersed by the diversion plate 18 and the force decreases, the water flows through the water passage holes 19 to enter the sedimentation area for rapid sedimentation, achieving reasonable guidance and distribution of the water flow and improving sedimentation efficiency. The main body 1 has a water injection hole 20 on its exterior. The water injection hole 20 is located on the exterior of the main body 1 and serves as the inlet for industrial wastewater to enter the interior of the main body 1. Wastewater is discharged into the interior of the main body 1 through the water injection hole 20 and begins to undergo sedimentation and purification treatment.

[0038] The inner wall of the main body 1 is provided with a first drain hole 21. After sedimentation, some wastewater containing turbid impurities will be discharged through the first drain hole 21, achieving the discharge of impurities after sedimentation and further improving the recycling of water resources. The inner wall of the main body 1 is also provided with a second drain hole 22. The function of the second drain hole 22 is similar to that of the first drain hole 21, also used to discharge wastewater containing impurities after sedimentation. By setting multiple drain holes, impurities are discharged more effectively, improving the sedimentation and purification effect. The outer side of the main body 1 is provided with a water outlet 23. The purified water after sedimentation and filtration will flow out from the water outlet 23 and be provided to subsequent use stages, realizing the purification and reuse of industrial wastewater.

[0039] The outer surface of movable plate 5 is in contact with the outer surface of top block 9. When movable plate 5 and movable plate 7 swing, their connection point moves downward, applying pressure to top block 9. This contact relationship transmits force, triggering subsequent actions such as compression of the S-shaped elastic element 10. The contact relationship between the outer surface of movable plate 5 and the outer surface of movable plate 7 ensures the coordinated movement of movable plate 5 and movable plate 7 during the swinging process, enabling them to swing stably with the locking pin 8 as the fulcrum.

[0040] The two ends of the locking pin 8 are fixedly connected to the inner wall of the baffle plate 2, and the outer side of the movable plate 5 is movably connected to the inner wall of the baffle plate 2. The locking pin 8 provides a fulcrum for the swing of the movable plate 5 and the movable plate 7. The movable connection of the movable plate 5 to the inner wall of the baffle plate 2 allows the movable plate 5 to swing when subjected to force without detaching from the baffle plate 2.

[0041] The movable plate 2 7 is externally connected to the inner wall of the baffle plate 2, and the button 3 is externally slidably connected to the inner wall of the baffle plate 2. The movable connection of the movable plate 2 7 to the inner wall of the baffle plate 2 ensures that it can swing in coordination with the movable plate 1 5, while the sliding connection of the button 3 to the inner wall of the baffle plate 2 ensures that the button 3 can accurately trigger the actions of the movable plate 1 5 and the movable plate 2 7 to adjust the baffle plate 2.

[0042] The working process of this utility model is as follows:

[0043] First, wastewater is discharged into the interior of the main body 1 through the water inlet 20. After sedimentation, the button 3 in the baffle plate 2 is pressed. At this time, the button 3 will move downwards under the guidance of the guide plate 4. The button 3 will then transmit force to the movable plate 5 and the movable plate 7. Since the movable plate 5 and the movable plate 7 are connected by the connecting column 6, and the two locking pins 8 pass through the movable plate 5 and the movable plate 7 respectively and are connected to the interior of the baffle plate 2, when the button 3 presses down on the movable plate 5 and the movable plate 7, the movable plate 5 and the movable plate 7 will be fixed by themselves. The pivot pin 8 swings, causing the connection between movable plate 1 5 and movable plate 2 7 to move downwards and apply pressure to the top block 9. At the same time, the top block 9 squeezes the S-shaped elastic element 10. The S-shaped elastic element 10 is compressed to ensure that movable plate 1 5 and movable plate 2 7 are no longer locked inside the slot 14 of the main body 1. At this time, the water discharge of the main body 1 can be determined by moving the baffle plate 2, avoiding the influence of water flowing into the next sedimentation tank before it has completely settled. The water flowing out will be filtered by the filter plate 16 behind, improving the water quality and working efficiency.

[0044] When water flows into the interior of the main body 1 through the water inlet 20, the large water flow will affect the sedimentation rate. Therefore, when the water flow is large, it will impact the diversion plate 18 in the fixed plate 17. Since the diversion plate 18 is triangular in shape, the water flow will be dispersed when it impacts the diversion plate 18, thus reducing the impact of the water flow. In addition, there are water passages 19 on both sides of the diversion plate 18. After the water flow is dispersed and the force decreases, it will enter the rear through the water passages 19 for rapid sedimentation. After the sedimentation is completed, the sewage with turbid impurities will be discharged through the drain hole 21, realizing the multi-stage sedimentation and purification effect and improving the recycling of water resources.
