Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a tunnel-based wastewater treatment equipment and treatment method. Background Technology

[0002] Tunnels generate a large amount of wastewater during construction and operation, primarily from construction dewatering, grouting wastewater, vehicle washing wastewater, tunnel seepage, and rainwater runoff from road surfaces. This wastewater typically contains impurities such as silt, suspended solids, petroleum pollutants, and alkaline substances from concrete. Direct discharge would cause turbidity and water quality deterioration in surrounding water bodies, damage soil and aquatic ecosystems, potentially clog municipal pipe networks, and affect the safety of surrounding farmland and waterways, while also failing to meet environmental emission standards. Therefore, it is essential to purify the wastewater using specialized wastewater treatment equipment. After treatment, the wastewater can have suspended solids removed, pH levels adjusted, and pollutant concentrations reduced, achieving compliant discharge and preventing environmental pollution and ecological damage. Some of the treated wastewater can even be reused for dust suppression during tunnel construction, equipment cleaning, and road watering, reducing fresh water consumption and lowering project operating costs. This approach not only meets environmental regulations but also enhances the green construction and sustainable operation of tunnel projects, ensuring harmonious development between the surrounding environment and the project.

[0003] Depending on the location of the tunnel, mobile treatment equipment is often required. Existing treatment equipment typically has a pre-filter installed directly at the front end. However, the pre-filter cannot be easily replaced or cleaned. When wastewater is mixed with chemicals, the mixing of the water cannot be guaranteed to be sufficient. At the same time, the sedimentation section can easily discharge the sediment, which can affect the water quality. Summary of the Invention

[0004] This invention provides a tunnel-based sewage treatment device and method. The device directly discharges the filtration, mixing, and sedimentation components in parallel, with a stable outer frame fixing them in place. Sewage is first directly injected into the filtration components, which filter the sewage and are easily lifted for replacement. An extension pipe is installed at the filtration components via a fixing component, through which sewage is injected into the mixing components. The mixing components are rotatably installed at the mixing components, and their rotation mixes the sewage with the chemical solution for use. The sedimentation components collect and settle the sewage. Finally, the discharge components are always positioned at the top of the sewage, ensuring stable discharge of sewage from the upper layer.

[0005] This invention provides a tunnel-based wastewater treatment equipment and method, specifically including: an outer frame; the outer frame is fixed to the outer ends of the filter assembly, mixing assembly, and sedimentation assembly; a fixing assembly is embedded in the filter assembly; an extension pipe is installed at the fixing assembly of the filter assembly; a hanging ring is installed at the top of the filter assembly; a mixing assembly is installed between the filter assembly and the sedimentation assembly; the top of the mixing assembly is connected to the sedimentation assembly; and a discharge assembly is snapped onto the sedimentation assembly.

[0006] Furthermore, an inner frame is installed at the inner end of the outer casing of the filter assembly. The inner frame is frame-shaped, and reinforcing strips are provided on the outer side of the outer casing. Filter plates are installed at the inner end of the outer casing, and the filter plates are arranged in a vertical array.

[0007] Furthermore, the extension plate of the fixing component is set at both ends of the top of the inner box frame of the filter component. The bottom of the extension plate contacts the reinforcing strip of the filter component. A hanging ring is fixedly installed on the extension plate. A vertical extension tube is installed at the slot of the extension plate. A clamping buckle is added to the outer end of the extension tube at the installation point of the extension plate.

[0008] Furthermore, the mixing chamber of the mixing component is provided with an auxiliary tank facing the sedimentation component, and the auxiliary tank is connected to the sedimentation component. A top frame rod is installed at the top of the mixing chamber, and a feed column is fixed in the middle of the top frame rod. A mixing frame is rotatably installed at the bottom of the feed column. The mixing frame and the feed column are connected by a snap-fit ​​block. Three sets of extension frames are provided on the mixing frame, and each set of extension frames is provided with a spray hole. The opposite side of the spray hole of the mixing frame extension frame is chamfered. A dispersion plate is rotatably installed in the middle of the interior of the mixing frame, and the outer wall of the dispersion plate has a spiral blade structure.

[0009] Furthermore, the sedimentation tank of the sedimentation component is provided with three sets of sedimentation pools, which are arranged in a stepped manner. Each set of sedimentation pools is provided with a top trough plate, which is designed with a serrated structure.

[0010] Furthermore, the support plate of the discharge component is configured as a plate frame, with a horizontal fastening rod screwed to the outer end of the support plate. Two sets of vertical column rods are provided at the front end of the support plate. The support plate is mounted on the sedimentation component, and the fastening rods are in contact with the outer wall of the sedimentation component. A sliding frame is slidably installed on the column rods. A connecting rod is hinged to the front end of the sliding frame. There are three sets of connecting rods, and the ends of the connecting rods are all connected to the bearing plate. Both ends of the bearing plate are equipped with floats. A discharge head is snapped onto the bearing plate. The outer wall of the discharge head is provided with holes. A sealing column is sleeved on the bottom of the discharge head, and the sealing column corresponds to the hole of the discharge head. An adjusting column is screwed to the bottom of the sealing column.

[0011] Furthermore, the process includes the following steps in sequence: 1. Wastewater is injected from the top of the filter assembly and filtered through the filter plates of the filter assembly. The four sets of filter plates form a successive filtration of the wastewater. 2. Install an extension pipe on the side of the inner box frame. The extension pipe extends directly into the bottom of the inner box frame. After the extension pipe is connected to the pipeline, the wastewater filtered at the bottom of the filter assembly is extracted. 3. After the wastewater is injected into the mixing component, the feed column of the mixing component is connected to the liquid medicine. The liquid medicine will pass through the dispersion plate in the middle of the mixing frame. The dispersion plate will rotate to distribute the liquid medicine. The liquid medicine is directly and evenly injected into each extension rod of the mixing frame. The liquid medicine is sprayed out from the side holes of the mixing frame. The mixing frame rotates under the reverse push of the sprayed liquid medicine. The rotating mixing frame will continuously spray out liquid medicine, which will mix the wastewater and ensure the mixing of the liquid medicine at the same time. 4. Wastewater is injected into each set of sedimentation tanks of the sedimentation components. The top of the sedimentation tank is set with a top trough plate. The sawtooth structure of the top trough plate will form an overflow of wastewater, discharging the debris floating on the top of the wastewater. 5. After receiving sewage, the sedimentation tank will achieve overall sedimentation. When sewage needs to be discharged, the discharge component is directly installed in the designated position of the sedimentation component. The fastening rod of the discharge component is tightened and fixed. The discharge head is snapped onto the support plate. The adjusting column of the discharge head is adjusted. A float ball is installed on the support plate to keep the support plate at the water surface. The sliding frame is set to a sliding installation method. The connecting rod is set to a parallelogram structure to better cooperate with the support plate to float on the water surface. At the same time, the discharge head is always at the bottom of the water surface. When the sealing column of the discharge head touches the bottom, it will close and stop the discharge head from being extracted, forming a self-locking mechanism.

[0012] This invention provides a tunnel-based sewage treatment device and method, which has the following beneficial effects: In this invention, the filtration assembly, mixing assembly, and sedimentation assembly are arranged and installed in a symmetrical manner. Wastewater is directly injected into the filtration assembly, which filters the wastewater and blocks impurities. Lifting rings are installed on the filtration assembly for easy hoisting. After the inner frame of the filtration assembly is lifted, the filter plate can be removed from the side for easy replacement and cleaning. An extension pipe is installed on the side of the inner frame and secured by a fixing assembly. The extension pipe directly draws wastewater into the mixing assembly. The mixing assembly allows for direct injection of external pharmaceutical solutions. The feed column and mixing frame are designed for rotation, allowing the pharmaceutical solution to spray out through the holes in the mixing frame, enabling the device to rotate at the bottom for better mixing of wastewater from the bottom. A dispersion disc is rotatably installed inside the mixing frame, which disperses the passing pharmaceutical solution. The system ensures uniform dispersion, guaranteeing even spraying across the mixing frame and stable mixing of wastewater within the mixing components. The sedimentation component features a multi-layered structure, incorporating a sedimentation tank and a top trough plate. The top trough plate has a serrated structure, allowing overflow from the sedimentation component to remove floating debris. A discharge component is installed at the sedimentation component, allowing for arbitrary installation. The discharge component's sliding frame is designed for sliding installation, and a support plate is connected to the sliding frame via a connecting rod with a parallelogram structure, facilitating use at any height. The support plate includes a float structure, ensuring the discharge head is always at the lower end of the liquid level, thus guaranteeing stable liquid extraction. A sealing column is fitted onto the discharge head; when the sealing column contacts the bottom, it preferentially slides to close the discharge head, achieving a limiting closure effect.

[0013] In addition, the filter assembly usually needs to discharge the filtered wastewater. Therefore, extension plates are set at both ends of the filter assembly. The extension plates are directly in contact with the reinforcing strips for reinforcement. After the extension pipe is directly installed on the extension plate, the water is discharged after the extension pipe is connected to the pipeline. After the extension pipe is installed, it is mainly fixed by the snap-fit ​​fastener. The snap-fit ​​fastener installation method allows the position of the extension pipe to be changed and adjusted.

[0014] Furthermore, the mixing tank is initially designed for mixing wastewater. After mixing, the wastewater needs to be discharged for further treatment. Therefore, an auxiliary trough is installed on the top of the mixing tank near the sedimentation component, allowing the auxiliary trough to directly connect with the sedimentation component. This enables the wastewater in the mixing component to be discharged to the sedimentation component through the auxiliary trough. The top frame rod of the mixing tank can fix the feed column, ensuring that the feed column is stably positioned in the middle, facilitating subsequent wastewater mixing. The dispersing disc contacts the tank, and the spiral blades of the dispersing disc evenly disperse and guide the liquid, allowing the liquid to be evenly injected into the extension frame of each mixing frame. At this point, the spray nozzles of the mixing frame can spray the liquid more evenly. When the mixing frame sprays the liquid, a counter-force will be generated, causing the mixing frame to rotate. The mixing frame has a chamfered structure, which allows for better rotation from the bottom, achieving temperature-controlled mixing of wastewater and liquid.

[0015] Furthermore, when installing the discharge assembly, the support plate is directly placed in the designated position. After ensuring the column is vertical, the fastening rod of the support plate is rotated so that it rests against the outer end of the sedimentation assembly, thus fixing the support plate and ensuring the stability of the column for convenient use of other components. First, the sliding frame is set to slide on the column, allowing it to slide up and down, ensuring the support plate can adapt to multiple height positions. A connecting rod is hinged at the front end of the sliding frame, and the end of the connecting rod is connected to the support plate, forming a parallelogram mechanism with three sets of connecting rods. This ensures the support plate remains horizontal at all times. The connecting rod increases the vertical floating position of the support plate. The float structure of the support plate allows the stones on the support plate to float on the water surface for use. When extracting wastewater from the lower end of the water surface, the discharge head is directly installed on the support plate, so that the discharge head hole is always at the lower end of the liquid surface, achieving stable extraction of treated wastewater. When the sealing column of the discharge head touches the bottom, the sealing column will push against the discharge head, so that the sealing column seals the hole at the discharge head, thereby achieving closure and preventing the discharge head from extracting the bottom sediment. An adjusting column is screwed to the bottom of the sealing column, so that the bottom-touching position of the sealing column can be adjusted by rotating the adjusting column, achieving the effect of early closure.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0020] Example 1: Please refer to Figures 1 to 8 : This invention proposes a tunnel-based sewage treatment equipment and method, comprising: an outer frame 1; the outer frame 1 is fixed to the outer ends of the filter assembly 2, the mixing assembly 4 and the sedimentation assembly 5, a fixing assembly 3 is embedded in the filter assembly 2, an extension pipe 7 is installed at the fixing assembly 3 of the filter assembly 2, a hanging ring buckle 8 is installed at the top of the filter assembly 2, the mixing assembly 4 is installed between the filter assembly 2 and the sedimentation assembly 5, the top of the mixing assembly 4 is connected to the sedimentation assembly 5, and a discharge assembly 6 is snapped onto the sedimentation assembly 5.

[0021] Among them, such as Figure 3 , Figure 4As shown, an inner frame 202 is installed at the inner end of the outer casing 201 of the filter assembly 2. The inner frame 202 is frame-shaped. Reinforcing strips 203 are provided on the outer side of the outer casing 201. Filter plates 204 are installed at the inner end of the outer casing 201. The filter plates 204 are arranged in a vertical array. Sewage will be preferentially injected from the filter assembly 2. In order to ensure that the sewage has less impurities, the filter plates 204 are directly installed inside the inner frame 202. The filter plates 204 are arranged in a vertical array, so that the sewage will be filtered multiple times and impurities will be isolated.

[0022] Among them, such as Figure 3 , Figure 4 As shown, the extension plate 301 of the fixing component 3 is set at both ends of the top of the inner box frame 202 of the filter component 2. The bottom of the extension plate 301 contacts the reinforcing strip 203 of the filter component 2. A hanging ring buckle 8 is fixedly installed at the extension plate 301. A vertical extension pipe 7 is installed at the slot of the extension plate 301. A clamping buckle 302 is added to the outer end of the extension pipe 7 at the installation location of the extension plate 301. Usually, the filter component 2 needs to discharge the filtered sewage. Therefore, the extension plate 301 is set at both ends of the filter component 2. The extension plate 301 directly contacts the reinforcing strip 203 for reinforcement. After the extension pipe 7 is directly installed at the extension plate 301, the water is discharged after the extension pipe 7 is connected to the pipeline. After the extension pipe 7 is installed, it is mainly fixed by the clamping buckle 302. The clamping installation method of the clamping buckle 302 allows the position of the extension pipe 7 to be changed and adjusted.

[0023] Among them, such as Figure 5 , Figure 6As shown, an auxiliary trough 402 is provided in the mixing tank 401 of the mixing component 4 facing the sedimentation component 5. The auxiliary trough 402 is connected to the sedimentation component 5. A top support rod 403 is installed on the top of the mixing tank 401, and a feed column 404 is fixed in the middle of the top support rod 403. The mixing tank 401 is initially used to mix sewage. After mixing the sewage, it needs to be discharged for further treatment. Therefore, the auxiliary trough 402 is installed on the top of the mixing tank 401 near the sedimentation component 5, so that the auxiliary trough 402 is directly connected to the sedimentation component 5. This allows the sewage in the mixing component 4 to be discharged to the sedimentation component 5 through the auxiliary trough 402. The top support rod 403 of the mixing tank 401 can fix the feed column 404, thereby ensuring that the feed column 404 is stably placed in the middle, which is convenient for subsequent sewage mixing. A mixing frame 406 is rotatably installed at the bottom of the feed column 404. The mixing frame 406 is connected to the feed column 404. The columns 404 are connected by snap-fit ​​blocks 405. The mixing frame 406 is equipped with three sets of extension frames, each with a spray hole. The spray holes on the extension frames of the mixing frame 406 are chamfered on the opposite side. A dispersing disc 407 is rotatably installed in the middle of the interior of the mixing frame 406. The outer wall of the dispersing disc 407 has a spiral blade structure. When the feed column 404 is injected with external medicine, it will slide down directly and contact the dispersing disc 407 in the middle of the mixing frame 406. The spiral blades of the dispersing disc 407 will evenly disperse and guide the liquid, so that the medicine is evenly injected into each set of extension frames of the mixing frame 406. At this time, the spray of medicine from the spray holes of the mixing frame 406 is more even. When the mixing frame 406 sprays out the medicine, a counter-thrust will occur, causing the mixing frame 406 to rotate. The mixing frame 406 has a chamfered structure, which allows it to rotate better from the bottom, achieving temperature-controlled mixing of medicine with wastewater.

[0024] Among them, such as Figure 2 , Figure 7 As shown, the sedimentation tank 501 of the sedimentation component 5 is equipped with three sets of sedimentation pools 502. The sedimentation pools 502 are arranged in a stepped manner. Each set of sedimentation pools 502 is equipped with a top trough plate 503. The top trough plate 503 is designed with a sawtooth structure. The sedimentation pools 502 on the sedimentation tank 501 are used for sedimenting sewage. The stepped arrangement of the sedimentation pools 502 allows the liquid in each place to be discharged one by one. The top trough plate 503 on the sedimentation pools 502 is designed with a sawtooth structure to allow debris, foam and other impurities on the water surface to overflow.

[0025] Among them, such as Figure 7 , Figure 8As shown, the support plate 601 of the discharge assembly 6 is configured as a plate frame. A horizontal fastening rod 602 is screwed onto the outer end of the support plate 601. Two sets of vertical support rods 603 are provided at the front end of the support plate 601. The support plate 601 is mounted on the sedimentation assembly 5, and the fastening rods 602 are in contact with the outer wall of the sedimentation assembly 5. When installing the discharge assembly 6, the support plate 601 is directly placed in the designated position. After ensuring the support rods 603 are vertical, the fastening rods 602 of the support plate 601 are rotated so that they press against the outer end of the sedimentation assembly 5, thus fixing the support plate 601 and ensuring the stability of the support rods 603 for easy installation. The component involves a sliding bracket 604 slidably mounted on the column 603. A connecting rod 605 is hinged to the front end of the sliding bracket 604. Three sets of connecting rods 605 are configured, each connected at its end to a bearing plate 606. Both ends of the bearing plate 606 have floats. The sliding bracket 604 is slidably mounted on the column 603, allowing it to slide up and down within the column 603, ensuring the bearing plate 606 can adapt to multiple height positions. The connecting rod 605 is hinged to the front end of the sliding bracket 604, and the end of the connecting rod 605 is connected to the bearing plate 606. The three sets of connecting rods 605 form a parallelogram mechanism, ensuring that the bearing plate 606 remains horizontal. The connecting rods 605 also increase the vertical floating position of the bearing plate 606. The float structure of the bearing plate 606 allows the stones to float on the water surface. A discharge head 607 is snapped onto the bearing plate 606. The outer wall of the discharge head 607 has holes, and a sealing column 608 is sleeved at the bottom of the discharge head 607, corresponding to the holes in the discharge head 607. An adjusting column 609 is screwed to the bottom of the sealing column 608 for adjustment. When the wastewater is drawn from the lower end of the water surface, the discharge head 607 is directly installed on the support plate 606, so that the hole of the discharge head 607 is always at the lower end of the liquid surface, achieving stable extraction of the treated wastewater. When the sealing column 608 of the discharge head 607 touches the bottom, the sealing column 608 will push up on the discharge head 607, so that the sealing column 608 seals the hole of the discharge head 607, thereby achieving closure and preventing the discharge head 607 from extracting the bottom sediment. The bottom of the sealing column 608 is screwed with an adjusting column 609, so that the adjusting column 609 can be rotated to adjust the bottom contact position of the sealing column 608, achieving the effect of early closure.

[0026] The process includes the following steps in sequence: 1. Wastewater is injected from the top of the filter assembly 2. The wastewater is filtered through the filter plate 204 of the filter assembly 2. The four sets of filter plates 204 form a successive filtration of the wastewater. 2. An extension pipe 7 is installed on the side of the inner box frame 202. The extension pipe 7 extends directly into the bottom of the inner box frame 202. After the extension pipe 7 is connected to the external pipeline, the wastewater filtered at the bottom of the filter assembly 2 is extracted. 3. After the wastewater is injected into the mixing component 4, the feed column 404 of the mixing component 4 is connected to the external medicine liquid. The medicine liquid will pass through the dispersion plate 407 in the middle of the mixing frame 406. The dispersion plate 407 will rotate to distribute the medicine liquid. The medicine liquid is directly and evenly injected into each extension rod of the mixing frame 406. The medicine liquid is sprayed out from the side holes of the mixing frame 406. The mixing frame 406 rotates under the reverse push of the sprayed medicine liquid. The rotating mixing frame 406 will continuously spray out medicine liquid, which will mix the wastewater and ensure the mixing of the medicine liquid. 4. Wastewater is injected into each set of sedimentation tanks 502 of sedimentation component 5. The top of sedimentation tank 502 is set with a top trough plate 503. The sawtooth structure of the top trough plate 503 will form an overflow of wastewater and discharge the debris floating on the top of the wastewater. 5. After receiving sewage, the sedimentation tank 502 will achieve overall sedimentation. When sewage needs to be discharged, the discharge component 6 is directly installed at the designated position of the sedimentation component 5. The fastening rod 602 of the discharge component 6 is fastened and fixed. The discharge head 607 is snapped onto the support plate 606. The adjusting column 609 of the discharge head 607 is adjusted. A float ball is installed at the support plate 606 to keep the support plate 606 at the water surface. The sliding frame 604 is set to a sliding installation method. The connecting rod 605 is set to a parallelogram structure to better cooperate with the support plate 606 to float on the water surface. At the same time, the discharge head 607 is always at the bottom of the water surface. When the sealing column 608 of the discharge head 607 touches the bottom, it will close and stop the discharge head 607 from being extracted, forming a self-locking mechanism.

[0027] The working principle of this invention is as follows: First, the sewage is directly injected into the filter assembly 2. The sewage passes through the filter plate 204 of the filter assembly 2. The multi-layered filter plate 204 filters the sewage. When the filter assembly 2 needs to be cleaned after use, the inner box frame 202 is directly installed with the lifting ring buckle 8 and the inner box frame 202 is lifted by the lifting ring buckle 8. This makes it easy to remove the filter plate 204 of the inner box frame 202, so as to facilitate the replacement and cleaning of the filter plate 204. After the wastewater is injected into the mixing component 4, the feed column 404 of the mixing component 4 is connected to the liquid medicine. The feed column 404 and the mixing frame 406 are rotated. At this time, the liquid medicine will pass through the dispersion plate 407 in the middle of the mixing frame 406. The dispersion plate 407 will rotate to distribute the liquid medicine, thereby ensuring that each extension rod of the mixing frame 406 is injected with liquid medicine. The holes of the mixing frame 406 are set on the side. After the liquid medicine is sprayed out through the holes, the mixing frame 406 is rotated by the counter thrust, thereby ensuring that the mixing frame 406 disperses the liquid medicine in the wastewater in the mixing component 4, and ensuring the mixing of the components of the liquid medicine in the wastewater. The sedimentation tanks 502 of the sedimentation assembly 5 are arranged in a stepped manner. Each sedimentation tank 502 has a top trough plate 503 along its top edge. The top trough plate 503 is serrated, allowing wastewater to overflow through the top trough plate 503 after being injected into the sedimentation tank 502, discharging floating debris from the top of the wastewater. The sedimentation tank 502 as a whole achieves sedimentation. A discharge assembly 6 is installed inside the sedimentation assembly 5. The discharge assembly 6 is directly installed using a fastening rod 602 and other structures. After the fastening rod 602 is tightened, it stably fixes the discharge assembly 6 in the designated position of the sedimentation assembly 5. The discharge head 607 can then be snapped onto the support plate 606. The adjusting column 609 of the discharge head 607 needs to be adjusted. A float ball is installed on the support plate 606 to keep the support plate 606 always at the water surface. The sliding frame 604 is set to a sliding installation method, and the connecting rod 605 is set to a parallelogram structure to better cooperate with the support plate 606 to float on the water surface. At the same time, the discharge head 607 is always at the bottom of the water surface. When the sealing column 608 of the discharge head 607 touches the bottom, it will close, stopping the extraction of the discharge head 607 and forming a self-locking mechanism.
