Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an environmentally friendly wastewater treatment device. Background Technology

[0002] According to existing data, wastewater treatment is a process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. There are many methods for treating wastewater, which can generally be summarized as a combination of physical, chemical, and biological methods. The main methods are to separate wastewater from solid waste, then disinfect harmful substances in the wastewater, and finally balance the microorganisms in the wastewater to make it meet the standards for discharge into the natural environment. Existing authorized patents and existing equipment with the same or similar technologies still have the following problems in daily use: Modern wastewater treatment plants typically remove various impurities from wastewater through multi-stage filtration and sedimentation. Sedimentation tanks remove stones, mud, and other small debris that cannot be removed during filtration. This debris (hereinafter referred to as sludge) settles in the sedimentation tank, allowing it to slowly accumulate at the bottom. Scrapers then remove the sludge from the bottom and any floating grease or oil on the surface. This method has significant drawbacks. First, it requires a considerable amount of time for the sludge to settle. Wastewater treatment plants handle various types of wastewater from an entire city daily, resulting in a heavy processing load. To meet daily treatment standards, multiple sedimentation tanks would need to be constructed and put into operation simultaneously. Second, the scrapers... When the sludge at the bottom is pushed, the scraper itself is resisted by the sewage. The force of the scraper's movement acts on the sewage, pushing it to form waves. The sewage will carry some lighter debris, such as sludge, and surge in the water. However, the scraper's target range is limited to the bottom of the tank. If the debris surges to the surface or away from the bottom, the scraper cannot effectively remove the debris completely. In the current operation of removing debris in sedimentation tanks, in order to reduce the sludge churning, the scraper's moving speed is reduced as much as possible to reduce the degree of sludge churning. However, regardless of the shape of the scraper, the moving speed, or the contact area with the water, the water will be driven to flow during the scraper's movement, which will cause the debris to surge. Therefore, complete solid-liquid separation cannot be achieved, and multi-stage sedimentation processes need to be added. Currently, the solid-liquid separation of sewage in sedimentation tanks involves scraping sludge into a sludge pool using a scraper, followed by pumping it out for further processing. However, it's known that firstly, the types of debris in sewage are uncontrollable, including stones of varying sizes and textures, as well as metal objects of different shapes and sizes. When pumping sludge, larger and heavier debris may not be able to be removed. Secondly, some harder stones or metal objects can damage the pump blades to varying degrees, exposing the internal metal directly to the corrosive sewage, further reducing the pump's lifespan and effectiveness. Furthermore, stones and metal objects cannot be processed together with the sludge to make fertilizer. Summary of the Invention

[0003] The purpose of this application is to solve or at least alleviate the problems existing in the prior art.

[0004] To address the aforementioned shortcomings, the present invention provides the following technical solution: an environmentally friendly wastewater treatment device, comprising a sedimentation tank body, wherein a separation component and a scraping component are disposed inside the sedimentation tank body, and two separation components are disposed on opposite sides inside the sedimentation tank body, and the two separation components are arranged in a mirror image. The separation component includes four mounting plates, which are respectively fixed to the front and rear edges of the top of the sedimentation tank body. The separation component is used to separate sludge in the sedimentation tank body. By controlling the direction of sewage flow, the sewage pushes the sludge to tumble and move towards the separation component. The separation component rotates in the opposite direction to the sewage flow to complete the sludge retrieval. The scraping assembly includes two slide rails, which are fixed to the front and rear edges of the top of the sedimentation tank body. The slide rails are located in the middle of the top of the sedimentation tank body. The scraping assembly works in conjunction with the separation assembly to classify the debris in the sedimentation tank body. The buoyancy of the water separates the sludge, stones, and metal blocks into layers in the sewage. The scraping assembly separately collects and treats the solid hard debris such as stones and metal blocks in the sedimentation tank body.

[0005] Furthermore, the separation assembly also includes two transmission rods located inside the sedimentation tank body. The two transmission rods are respectively located in the middle of two sets of mounting plates. The front and rear ends of the transmission rods extend through the sedimentation tank body to the outside of the sedimentation tank body. The transmission rods are rotatably connected to the sedimentation tank body through a rotary seal. Three retrieval frames are evenly fixed on the surface of the transmission rods.

[0006] Furthermore, a scooping net is fixedly connected inside the scooping frame, and a thin metal plate is fixedly fitted on the surface of the scooping frame. A contact ball is fixedly connected to the side of the thin metal plate away from the transmission rod.

[0007] Furthermore, an arc-shaped abutment plate is fixedly connected to the middle of each set of mounting plates, a guide plate one is fixedly connected to the side of the retrieval frame near the transmission rod, a guide plate two is fixedly connected to the side of each mounting plate away from each other, and an arched guide rod is evenly fixedly connected to the side of the guide plate two away from the mounting plate.

[0008] Furthermore, both sides inside the sedimentation tank body are rotatably connected to a roller via a rotating seal. The front and rear ends of the roller extend through the sedimentation tank body to the outside of the sedimentation tank body. The front and rear ends of the roller and the transmission rod are fixedly connected to transmission wheels. The two transmission wheels on the same side are wrapped with transmission belts.

[0009] Furthermore, a collection pipe is provided above the roller, and the collection pipe is fixedly connected to the inner wall of the sedimentation tank body. The top end of the collection pipe is evenly provided with an inlet, which connects the inside of the collection pipe with the outside. Both ends of the collection pipe extend to the outside of the sedimentation tank body.

[0010] Furthermore, a push plate is provided inside the collecting tube, and magnetic rods are fixedly connected to both the front and rear sides of the bottom of the push plate. The magnetic rods extend to the bottom of the collecting tube. Magnetic blocks are evenly fixedly connected to both the front and rear ends of the roller, and the magnetic blocks and magnetic rods repel each other.

[0011] Furthermore, the scraping assembly also includes a slide rod, which is slidably connected to a slide rail. The slide rod is located on one side of the two slide rails that are close to each other. A spring is provided inside the slide rail, and the two ends of the spring are fixedly connected to the inner wall of the slide rail and the surface of the slide rod, respectively. A push rod is hinged to both ends of the slide rod.

[0012] Furthermore, a float plate is provided in the middle of the slide rail, and a scraper is hinged to the bottom end of the push rod one. Two push rods two are hinged to the side of the float plate near the slide rail. The bottom ends of the push rods two are rotatably connected to the surface of the push rod one on the same side. The push rods two and push rod one on the same side are both in a figure-eight shape.

[0013] Compared with the known prior art, the technical solution provided by this invention has the following beneficial effects: 1. By setting up a separation component, the solids in the sewage are separated into solids and liquids. This device abandons the traditional method of sedimentation followed by scraping. By controlling the flow of sewage, the sludge is stirred up and scooped up in the sewage. The sludge is then flushed against the scooping frame and net, thereby improving the scooping effect. Compared with the traditional solid-liquid separation method, this device does not require waiting for the sludge to settle completely in the sedimentation tank. The sludge removal operation can be carried out directly after sewage is discharged into the sedimentation tank. Compared with the two methods, this device can be operated directly, which improves the overall sewage treatment speed and saves the time waiting for sludge to settle. 2. Compared with the traditional scraping method, this device operates in reverse. It not only classifies and treats impurities, but also completely removes impurities from sewage in one operation without the need for multiple sedimentation, thus reducing the cost of sewage treatment. Manufacturers also do not need to build multiple sedimentation tanks for sedimentation operations at the same time. In addition, the traditional scraping method requires slow operation to avoid sludge churning in the sewage. However, even if the scraper is slow, it will still drive the water flow and cause sludge to churning, resulting in incomplete scraping. This device can be put into purification operation directly without waiting, which greatly increases the daily sewage treatment capacity of the treatment plant, thereby meeting the sewage treatment needs of the city. 3. This device classifies and treats impurities in wastewater. Stones and metal blocks are removed separately for landfill disposal, avoiding mixing with sludge and reducing the difficulty of sludge reprocessing. At the same time, there is no need to use a sludge pump to extract sludge, avoiding damage to the sludge pump caused by stones and metal blocks. In addition, the sludge is collected separately for composting. Utilizing the rich microorganisms and organic matter in it, better fertilizer can be obtained or fermentation can produce methane, completing energy recycling. 4. By setting up a scraping component and a separation component to work together, the separation component collects and processes sludge, while the scraping component gathers and processes debris such as stones or metal blocks. The two complement each other, and the entire process quickly completes the processing of different types of debris. After the separation component completely removes sludge and grease, the scraping component can directly process stones, metal blocks, and other debris. This device can completely remove all kinds of debris from wastewater in one operation, reducing multi-stage sedimentation treatment to a single solid-liquid separation operation, greatly reducing the entire treatment process and the time required.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to embodiments.

[0018] This embodiment provides an environmentally friendly wastewater treatment device, such as... Figures 1-12As shown, the sedimentation tank body 101 includes a separation component 200 and a scraping component 300 inside the sedimentation tank body 101. There are two separation components 200, which are distributed on both sides inside the sedimentation tank body 101 in a mirror image arrangement. As a preferred embodiment of this example, Figures 1-12 As shown, the separation component 200 includes four mounting plates 201, which are respectively fixed to the front and rear edges of the top of the sedimentation tank body 101. The separation component 200 is used to separate the sludge in the sedimentation tank body 101. By controlling the direction of sewage flow, the sewage pushes the sludge to tumble and move towards the separation component 200. The separation component 200 rotates in the opposite direction to the sewage flow to complete the sludge retrieval. The separation assembly 200 also includes two transmission rods 202, which are located inside the sedimentation tank body 101. The two transmission rods 202 are located in the middle of the two sets of mounting plates 201 respectively. The front and rear ends of the transmission rods 202 extend through the sedimentation tank body 101 to the outside of the sedimentation tank body 101. The transmission rods 202 and the sedimentation tank body 101 are rotatably connected by a rotary seal. Three retrieval frames 203 are evenly fixed on the surface of the transmission rods 202. As a preferred embodiment of this example, Figures 1-12 As shown, a scooping net 204 is fixedly connected inside the scooping frame 203. A thin metal plate 205 is fitted on the surface of the scooping frame 203. A contact ball 206 is fixedly connected to the side of the thin metal plate 205 away from the transmission rod 202. An arc-shaped contact plate 208 is fixedly connected to the middle of each set of mounting plates 201. A guide plate 207 is fixedly connected to the side of the scooping frame 203 near the transmission rod 202. A guide plate 209 is fixedly connected to the side of the mounting plates 201 away from each other. An arched guide rod 210 is evenly fixedly connected to the side of the guide plate 209 away from the mounting plate 201. It should be noted that the scooping net 204 is woven from high-strength nylon material. A strip of semi-circular contact strip is evenly fixed to the bottom end of the contact plate 208. The cross-section of 207 is a regular pentagon, and the cross-section of the guide plate 209 is a right trapezoid. Both sides inside the sedimentation tank body 101 are rotatably connected to the rollers 211 through the rotary seal. The front and rear ends of the rollers 211 extend through the sedimentation tank body 101 to the outside of the sedimentation tank body 101. The front and rear ends of the rollers 211 and the transmission rod 202 are fixedly connected to the transmission wheels 212. The two transmission wheels 212 on the same side are wrapped with transmission belts 213. It should be noted that the transmission wheels 212 stretch the transmission belts 213 to a taut state. The transmission wheels 212 are twisted into a figure-eight shape. When the transmission wheels 212 rotate, the transmission belts 213 pull the other connected transmission wheel 212 to rotate, and the two transmission wheels 212 rotate in opposite directions. As a preferred embodiment of this example, Figures 1-12 As shown, a collection pipe 214 is provided above the roller 211. The collection pipe 214 is fixedly connected to the inner wall of the sedimentation tank body 101. An inlet 215 is evenly provided at the top of the collection pipe 214, which connects the inside of the collection pipe 214 to the outside. Both ends of the collection pipe 214 extend to the outside of the sedimentation tank body 101. A push plate 216 is provided inside the collection pipe 214. Magnet rods 217 are fixedly connected to the front and rear sides of the bottom of the push plate 216. The magnet rods 217 extend to the bottom of the collection pipe 214. Magnet blocks 218 are evenly fixedly connected to both the front and rear ends of the roller 211. The magnet blocks 218 and the magnet rods 217 repel each other. It should be noted that two-thirds of the part below the surface of the collection pipe 214 is below the sewage liquid surface, that is, the inlet 215 is above the liquid surface. The front and rear ends of the collection pipe 214 are in a through state.

[0019] Compared with existing authorized patents and devices with the same or similar technologies, the following effects are achieved: Abandoning the traditional method of sedimentation followed by scraping, this device controls the flow of sewage to cause the sludge to churn, thereby scooping up the sludge churning in the sewage and flushing the sludge with the scooping frame 203 and the scooping net 204, thus improving the scooping effect. Compared with the traditional solid-liquid separation method, this device does not require waiting for the sludge to completely settle in the sedimentation tank body 101. The sludge removal operation can be carried out directly after sewage is discharged into the sedimentation tank body 101. Wastewater is sorted and treated, with stones and metal blocks removed separately for landfill disposal. This avoids mixing stones and metal blocks with sludge, reducing the difficulty of sludge reprocessing. It also eliminates the need for sludge pumps, preventing damage to the pumps from stones and metal blocks. Furthermore, the sludge is collected separately for composting, utilizing its rich microorganisms and organic matter to obtain excellent fertilizer or fermentation to produce methane, thus achieving energy recycling.

[0020] At other levels, this embodiment also provides an environmentally friendly wastewater treatment device, such as... Figures 1-12 As shown, the scraping component 300 includes two slide rails 301. The slide rails 301 are fixed to the front and rear edges of the top of the sedimentation tank body 101. The slide rails 301 are located in the middle of the top of the sedimentation tank body 101. The scraping component 300 cooperates with the separation component 200 to classify the debris in the sedimentation tank body 101. The buoyancy of the water separates the sludge, stones and metal blocks into layers in the sewage. The scraping component 300 separately collects and treats the solid hard debris such as stones and metal blocks in the sedimentation tank body 101. As a preferred embodiment of this example, Figures 1-12As shown, the scraping assembly 300 also includes a slide rod 302, which is slidably connected to the slide rail 301. The slide rod 302 is located on the side of the two slide rails 301 that are close to each other. A spring 303 is provided inside the slide rail 301. The two ends of the spring 303 are fixedly connected to the inner wall of the slide rail 301 and the surface of the slide rod 302, respectively. Push rods 304 are hinged to both ends of the slide rod 302. It should be noted that the scraper 307 is horizontally slidably connected to the inner wall of the sedimentation tank body 101, and the bottom end of the scraper 307 contacts the bottom inner wall of the sedimentation tank body 101. As a preferred embodiment of this example, Figures 1-12 As shown, a float plate 305 is provided in the middle of the slide rail 301, and a scraper 307 is hinged to the bottom end of the push rod 304. Two push rods 306 are hinged to the side of the float plate 305 near the slide rail 301. The bottom ends of the push rods 306 are rotatably connected to the surface of the push rod 304 on the same side. The push rods 306 and the push rod 304 on the same side are both in a figure-eight shape.

[0021] Compared with existing authorized patents and devices with the same or similar technologies, the following effects are achieved: The scraping component 300 can directly handle debris such as stones and metal blocks. This device can completely remove all kinds of debris from sewage in one operation, reducing multi-stage sedimentation treatment to a single solid-liquid separation operation, which greatly reduces the entire treatment process and the time required.

[0022] The complete working principle and process described above are as follows: Please refer to Figures 1-12 The following is the specific working process of the separation component 200; First, the wastewater is filtered through a screen and then injected into the sedimentation tank body 101. Then, the user fixes the external motor to the end of the transmission rod 202 and starts the motor. The motor drives the transmission rod 202 to rotate. (Refer to...) Figure 5 The transmission rod 202 drives the retrieval frame 203 and its connected parts to rotate. The retrieval frame 203 drives the retrieval net 204 to perform a retrieval operation in the sewage. It is known that the retrieval net 204 is woven from high-strength nylon material. The retrieval net 204 is woven into a high-density mesh, which can effectively retrieve sludge from the sewage. At the same time, the mesh structure of the retrieval net 204 can reduce water resistance. (Reference) Figure 8When the transmission rod 202 rotates, it drives the transmission wheel 212 fixed on it to rotate. The transmission wheel 212 drives the transmission wheel 212 connected to the roller 211 to rotate via the transmission belt 213. It is known that the transmission wheel 212 stretches the transmission belt 213 to a taut state, and the transmission wheel 212 twists into a figure-eight shape. When the transmission wheel 212 rotates, it pulls the other connected transmission wheel 212 to rotate via the transmission belt 213, and the two transmission wheels 212 rotate in opposite directions. The transmission wheel 212 drives the roller 211 to rotate in the opposite direction to the transmission rod 202 and the retrieval frame 203. During the rotation of the roller 211, the roller 211 agitates the sewage, pushing the sewage to surge. The sewage carries light sludge and debris and surges in the sedimentation tank body 101 to... Figure 3 For reference, the roller 211 rotates counterclockwise, and the transmission rod 202 drives the scooping frame 203 and the scooping net 204 to rotate clockwise. The roller 211 pushes the sewage towards the direction closer to the transmission rod 202. The sewage, carrying sludge, opposes the scooping frame 203 and the scooping net 204 rotating in the opposite direction, thereby assisting the scooping net 204 to more thoroughly scoop up the sludge. In addition, the rotation of the roller 211 agitates the sewage, assisting the sludge in the sewage to be agitated by the water force, while stones and metal blocks... Once the objects can no longer be propelled and churned by water, the sludge is separated from the stones and metal blocks. The sludge can be recycled for composting, while the stones and metal blocks have a negative effect on the composting process. The separation of the two can be achieved with the help of water flow. As the scooping frame 203 and scooping net 204 rotate the scooped sludge to the contact plate 208, the bottom end of the contact plate 208 is uniformly fixed with strip-shaped semi-circular contact strips. When the scooping frame 203 drives the contact ball 206 to contact the semi-circular contact strips at the bottom end of the contact plate 208... When the sludge plates collide, they impact each other, causing the metal plate 205 to vibrate. This vibration, combined with the impact of the metal plate 205 with the net 204, causes the net 204 to shake, accelerating the flow of sludge into the guide plate 207. The cross-section of the guide plate 207 is a regular pentagon. Under gravity, the sludge flows to both sides inside the guide plate 207 and into the guide plate 209. The cross-section of the guide plate 209 is a right trapezoid. The sludge then flows through the guide plate 209... 209 guides the sludge flow. The guide rod 210 intercepts smaller particles such as stones or metal pieces in the sludge. As shown in the diagram, the guide rod 210 is arched, guiding the intercepted stones or metal pieces to flow to both sides. The sludge, being a viscous gel, is not blocked by the guide rod 210 but passes through its lower part and continues to flow on the guide plate 209, completely separating the sludge from the stones and metal pieces. (Reference) Figure 8As the retrieval frame 203 and retrieval net 204 rotate, the sewage also surges upwards. The direction of the sewage surge is upwards and away from the drive rod 202, forming a wave on the liquid surface. The sewage pushes the floating grease and debris towards the collection pipe 214. The wave carries the grease into the collection pipe 214 through the inlet 215. The gravity of the sewage and grease causes the collection pipe 214 and the magnetic rod 217 to move downwards. As the roller 211 rotates, it drives the magnetic blocks 218 to rotate. The six magnetic blocks 218 are fixed at equal intervals on the roller 211. When the magnetic blocks 218 rotate to directly below the magnetic rod 217, the magnetic rod 217 and the magnetic blocks 218 repel each other, and the magnetic repulsion pushes the magnetic rod 217 upwards. The magnetic rod 217 drives the push plate 216 to push the sewage and grease inside the collection pipe 214. Because the two ends of the collection pipe 214 are connected and the push plate 216 is in a flat state, when the push plate 216 pushes the sewage and grease, the sewage and grease are quickly discharged from both ends of the collection pipe 214 to the outside of the device, instead of flowing back from the inlet 215. The user can connect the two ends of the collection pipe 214 to water pipes to guide the sewage and grease into the designated position, so as to avoid the sewage in the collection pipe 214 from carrying the grease on the liquid surface to surge back into the sedimentation tank body 101. According to the above movement process, the transmission rod 202 is the first rotating shaft connected to the motor. Driven by the transmission wheel 212 and the transmission belt 213, the rotation speed and rotation angle of the roller 211 and the magnet block 218 are synchronized with the transmission rod 202. Therefore, the above-mentioned sludge retrieval, magnet rod 217 and push plate 216 assist the collection of sewage and grease in the collection pipe 214 at the same time. The effects obtained from the above process are as follows: By setting up the separation component 200, the separation component 200 performs solid-liquid separation on the solid impurities in the sewage. This device abandons the traditional method of sedimentation followed by scraping. By controlling the sewage to surge, the sludge is stirred up, thereby scooping up the sludge in the sewage. The sludge is flushed against the scooping frame 203 and the scooping net 204, thereby improving the scooping effect. Compared with the traditional solid-liquid separation method, this device does not need to wait for the sludge to settle completely in the sedimentation tank body 101. The sludge removal operation can be carried out directly after the sewage is discharged into the sedimentation tank body 101. Compared with the two methods, this device can be operated directly, improving the overall sewage treatment speed and saving the time of waiting for sludge to settle. Compared to traditional scraping methods, this device operates in reverse, not only classifying and treating debris but also completely removing it from wastewater in a single operation without the need for multiple sedimentation processes. This reduces wastewater treatment costs, and manufacturers no longer need to build multiple sedimentation tanks for simultaneous sedimentation. Traditional scraping methods require a slow process to prevent sludge from churning in the wastewater, but even with a slow scraper, the water flow still causes sludge to churn, resulting in incomplete removal. This device can be put into purification operation directly without waiting, greatly increasing the daily wastewater treatment capacity of the treatment plant and thus meeting the wastewater treatment needs of the city. This device classifies and treats impurities in wastewater, removing stones and metal blocks separately for landfill disposal, thus avoiding mixing with sludge and reducing the difficulty of sludge reprocessing. It also eliminates the need for sludge pumps to extract sludge, preventing damage to the pumps from stones and metal blocks. Furthermore, the sludge is collected separately for composting, utilizing its rich microorganisms and organic matter to obtain excellent fertilizer or fermentation to produce methane, thus achieving energy recycling. Please refer to Figures 1-12 The following is the specific working process of the scraping component 300; Initially, spring 303 is in a deformed, compressed state under the pressure of slide rod 302. After the separation component 200 completely removes the sludge from the sewage, the user discharges the sewage from the sedimentation tank body 101 into the next treatment process. As the water level in the sedimentation tank body 101 continues to drop, the spring force of spring 303 pushes slide rod 302 down. Slide rod 302 drives push rod 304, which is rotatably connected to it, to descend simultaneously. Because the scraper 307 at the bottom of push rod 304 is horizontally slidably connected to the sedimentation tank body 101, push rod 304 on the same side is pushed by slide rod 302 to rotate in a figure-eight shape. The two scrapers 307 move in opposite directions. The sedimentation tank body 101 pushes and gathers the stones, metal blocks, and other debris deposited at the bottom. After the sewage in the sedimentation tank body 101 is completely discharged, the user collects the stones and metal blocks for subsequent reuse or landfill disposal. Then, the user continues to inject a mixture of sludge and sewage into the sedimentation tank body 101. As the sewage level in the sedimentation tank body 101 continues to rise, the buoyancy of the sewage acts on the float plate 305, causing the float plate 305 to gradually rise. The float plate 305 drives the above motion process in the opposite direction, so that the slide bar 302 continues to be compressed. After the next sewage discharge, the above motion process continues to push and gather the stones and metal blocks. The effect obtained from the above process is as follows: by setting up the scraping component 300 and the separation component 200 to work together, the separation component 200 collects and processes the sludge, while the scraping component 300 gathers and processes debris such as stones or metal blocks. The two complement each other and quickly complete the processing of different types of debris throughout the process. After the separation component 200 completely removes the sludge and grease, the scraping component 300 can directly process the stones and metal blocks. This device can completely remove all kinds of debris from the sewage in one operation, reducing the multi-stage sedimentation process to a single solid-liquid separation operation, greatly reducing the entire processing process and the time required.
