Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for sewage tank equipment, and more particularly to an integrated classified sewage treatment tank and method. Background Technology

[0002] With the rapid advancement of global urbanization and the dramatic expansion of urban populations, the volume of domestic sewage discharge has increased significantly. This untreated sewage is directly discharged into the surrounding environment, causing severe water pollution and exacerbating water scarcity. Domestic sewage is rich in organic matter, nutrients, pathogens, and other pollutants; if not properly treated, it will further deteriorate water quality, accelerate environmental degradation, and pose a threat to human health and ecological balance.

[0003] Given the urgency and importance of wastewater treatment, higher requirements have been placed on it, emphasizing that domestic sewage must meet discharge standards or be reused as a resource. Against this backdrop, wastewater treatment technologies have developed significantly, encompassing various advanced technologies such as biological treatment, membrane treatment, and advanced oxidation. The application of these technologies has effectively improved wastewater treatment efficiency and effluent quality.

[0004] Currently, one of the most common wastewater treatment equipment on the market is the vacuum truck. As an important tool for urban wastewater treatment, vacuum trucks are widely used in the environmental protection field. Their working principle mainly relies on the negative pressure effect generated by a vacuum pump to suck wastewater from the discharge port into the tank, and then transport it to a designated location for centralized treatment. However, in practical applications, vacuum trucks suffer from problems such as cumbersome processing procedures and low efficiency. Specifically, vacuum trucks need to complete multiple steps, including wastewater suction, discharge, and transportation to the treatment plant. The entire process is time-consuming and highly dependent on operators, affecting the overall practicality and efficiency of the equipment.

[0005] In summary, existing wastewater treatment technologies still need improvement in terms of treatment efficiency and ease of operation. Therefore, developing an integrated wastewater treatment system that simplifies treatment steps and improves efficiency is particularly important. This invention was developed to address these shortcomings, aiming to achieve automated, efficient, and intensive wastewater treatment through innovative technological means. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an integrated wastewater treatment tank and method, which solves the problem that the existing wastewater treatment devices are complex in structure and cumbersome in steps, resulting in low treatment efficiency.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an integrated wastewater treatment tank, including a tank body and treatment equipment. The treatment equipment further includes a closing assembly, an absorption device, a separation device, a clamping mechanism, and a cleaning device. The tank body is hollow, with a fixed cover plate at one end and a working chamber inside. The cleaning device is installed and fixed at the fixed cover plate end of the tank body, and its scraper is installed in the working chamber. Mounting seats are provided on both sides of the tank body. The screw of the closing assembly is installed on the mounting seat. When the screw rotates, it drives the box cover installed at the other end of the tank body to open and close. A feed inlet is provided at the top of the working chamber. The input end of the absorption device is connected to the feed inlet. An organic hole is opened in the box cover of the closing assembly. The screw of the separation device is installed in the machine hole, driving multiple sets of filter cloths of the separation device to move back and forth in the separation box. The clamping mechanism is located at the top of the tank body. The tank body and the closing assembly are closed and fastened through the pin at the top of the box cover. A sealing groove is provided on the side of the tank body, and a sealing ring is installed in the groove.

[0008] In a preferred embodiment, the closing assembly includes a set of first lead screws rotatably connected to two sets of mounting seats at both ends of the tank body. One end of the first lead screw is equipped with a drive motor, and the other end is rotatably mounted to the mounting seat. The middle part is rotatably connected to a baffle. One end of the baffle is fixed to the tank cover, and a set of brackets is fixed at the bottom of the tank body.

[0009] In a preferred embodiment, the closing assembly further includes a vacuum pump fixed to a fixed cover plate on the tank body. The outlet end of the vacuum pump is connected to a three-way valve. Of the other two circuits of the three-way valve, one is connected to the top of the tank body, and the other is connected to the bottom of the tank body through a hole in the fixed cover plate.

[0010] In a preferred embodiment, the absorption device includes a feed pipe connected to the feed inlet, the feed pipe being fixed on a rotating base, the rotating base being rotatably mounted on the tank body and connected to the feed inlet, a driven gear being mounted on the rotating base, the driven gear meshing with a drive gear, the drive gear being driven by a servo motor, the drive gear being fixed to the top of the tank body by a mounting plate, a hinge being rotatably mounted on the top of the rotating base, a water suction pipe being fixed on the hinge, the water suction pipe being connected to the feed pipe, a hydraulic cylinder being mounted at the bottom of the hinge, and the other end of the hydraulic cylinder being fixed on the rotating base.

[0011] In a preferred embodiment, the separation device includes a second lead screw rotatably mounted on the box cover. One end of the second lead screw is equipped with a stepper motor, and the other end is fixed to the separation box. One end of the separation box is fixed to the box cover via a connecting plate. The bottom of the separation box is densely provided with filter holes. A set of guide rails is installed on both sides of the upper part of the separation box. Several sliding beams are installed on the set of guide rails. The second lead screw is sequentially inserted into the middle of several sliding beams and screwed to them. Several steel filter screens are installed at the bottom of the sliding beams. The bottom ends of each steel filter screen are rotatably connected to form a continuous filter belt.

[0012] In a preferred embodiment, the separation device further includes a drain outlet located at the bottom of the tank cover. When the separation device is closed with the working chamber of the tank via the closing assembly, the drain outlet is connected to the bottom of the working chamber.

[0013] In a preferred embodiment, the separation device further includes inclined baffles installed on both sides of the separation tank, which, together with the separation tank, form a funnel shape for receiving sewage.

[0014] In a preferred embodiment, the locking mechanism includes an electric turntable fixed to the top of the tank. The electric turntable includes a rotary motor and a turntable. A buckle is fixed to the front end of the turntable, and a pin is provided on the top of the tank cover. When the closing component drives the tank to close with the tank, the electric turntable rotates, causing the buckle to rotate to the rear of the pin on the top of the tank cover and lock, thereby achieving the locking and sealing of the integrated classified sewage treatment tank.

[0015] In a preferred embodiment, the cleaning device includes a set of telescopic poles fixed to a tank cover. The front ends of the telescopic poles are connected to a scraper, which is installed inside the tank and flush with the inner surface of the tank.

[0016] An integrated wastewater separation treatment method, employing any of the aforementioned integrated wastewater separation treatment tanks, includes the following steps:

[0017] Step 1: After the integrated classified sewage treatment tank is installed in place, the buckle of the clamping mechanism is initially positioned on the top surface of the tank. Start the drive motor, and the drive motor drives the first lead screw to rotate, which drives the baffle that is screwed with it to move towards the tank. The cover that is fixed to the baffle moves in the same direction, and the separation device and pin that are fixed to the cover move in the same direction and synchronously until the cover is pressed tightly against the side of the tank.

[0018] Step 2: Start the electric turntable's rotary motor to drive the turntable to rotate. The turntable will cause the buckle fixed to it to rotate to the rear of the top pin of the tank cover, locking it in place and simultaneously locking and sealing the integrated wastewater treatment tank.

[0019] Step 3: Start the servo motor of the absorption device, drive the drive gear to rotate, drive the driven gear meshing with it to rotate, drive the rotating seat to rotate, drive the pumping pipe to swing horizontally, so that it is horizontally opposite to the sewage source, start the hydraulic cylinder, drive the hinge seat to rotate, and drive the pumping pipe inlet to align with the sewage source.

[0020] Step 4: Wastewater enters the separation device through the feed inlet. Start the stepper motor. The stepper motor rotates, which drives the second lead screw to rotate. The second lead screw drives the slider beam to move. The slider beam drives the steel filter screen belt to move, filtering the sludge in the wastewater. The water enters the tank through the steel filter screen and the filter holes at the bottom of the separation box and is discharged through the drain outlet. At the same time, the slider beams move closer layer by layer, compressing the sludge left in the filter cloth into a cake shape.

[0021] Step 5: Start the electric turntable's rotary motor. The rotary motor reverses, causing the turntable to rotate in the opposite direction. The turntable then rotates the buckle that is fixed to it to the top of the tank, separating it from the pin and releasing the closing assembly.

[0022] Step 6: Start the drive motor. The drive motor reverses and drives the first lead screw to rotate in the opposite direction. This causes the baffle that is engaged with it to move away from the tank. The cover that is fixed to the baffle moves away from the tank together. The separation device and the pin that are fixed to the cover move away from the tank in the same direction and synchronously until the separation device is removed from the working chamber of the tank.

[0023] Step 7: Start the stepper motor. The stepper motor rotates in the reverse direction, which drives the second lead screw to rotate in the reverse direction. The second lead screw drives the slider beam to move in the reverse direction. The slider beam drives the steel filter belt to move in the reverse direction. Each layer of steel filter unfolds and the cake-shaped sludge inside is removed.

[0024] Step 8: Repeat Step 2 to Step 3, open the three-way valve, start the vacuum pump, and introduce water into the top and bottom of the tank to clean the working chamber of the tank. Start the telescopic pole, and the telescopic pole will push the scraper to scrape the bottom of the working chamber of the tank. The cleaned water will be discharged through the drain port. When treating sewage again, repeat Step 4 to Step 7.

For example, the tank is sealed and opened / closed through a closure assembly, and wastewater and sludge are separated through a separation device. These ingenious structural designs provide new ideas for the innovation of wastewater treatment equipment.

[0033] 8.

The cover 306 opens and closes, and the top of the working chamber 201 is provided with a feed inlet 203. The input end of the absorption device is connected to the feed inlet 203. An organic hole is opened in the cover 306 of the closing component. The lead screw of the separation device is inserted into the machine hole, which drives the multiple sets of filter cloths 507 of the separation device to move back and forth in the separation box 504. The clamping mechanism is set at the top of the tank body 1. The tank body 1 is closed and fastened to the closing component through the pin 603 at the top of the cover 306. A sealing groove is provided on the side of the tank body 1, and a sealing ring is installed in the groove.

[0048] In this embodiment, the closing assembly includes a set of first lead screws 304 that are rotatably connected to two sets of mounting seats 202 at both ends of the tank body 1. A drive motor 303 is installed at one end of the first lead screw 304, and the other end is rotatably installed with the mounting seat 202. The middle part is rotatably connected to the baffle 305. One end of the baffle 305 is fixed together with the box cover 306. A set of brackets 307 is fixed at the bottom of the tank body 1.

[0049] Furthermore, the closing assembly also includes a vacuum pump 301 fixed to the fixed cover plate of the tank body 1. The outlet end of the vacuum pump 301 is connected to a three-way valve 302. The other two circuits of the three-way valve 302 are connected to the top of the tank body 1 and the other circuit is connected to the bottom of the tank body 1 through a hole in the fixed cover plate.

[0050] Furthermore, the absorption device includes a feed pipe 401 connected to the feed inlet 203. The feed pipe 401 is fixed on a rotating base 406, which is rotatably mounted on the tank body 1 and connected to the feed inlet 401. A driven gear 405 is mounted on the rotating base 406, which meshes with a drive gear 404. The drive gear 404 is driven by a servo motor 403 and is fixed to the top of the tank body 1 by a mounting plate 402. A hinge 409 is rotatably mounted on the top of the rotating base 406, and a water suction pipe 407 is fixed on the hinge 409. The water suction pipe 407 is connected to the feed pipe 401. A hydraulic cylinder 408 is mounted at the bottom of the hinge 409, and the other end of the hydraulic cylinder 408 is fixed on the rotating base 406.

[0051] Furthermore, the separation device includes a second lead screw 502 rotatably mounted on the box cover 306. One end of the second lead screw 502 is equipped with a stepper motor 501, and the other end is fixed to the separation box 504. One end of the separation box 504 is fixed to the box cover 306 through a connecting plate 503. The bottom of the separation box 504 is densely provided with filter holes. A set of guide rails 505 are installed on both sides of the upper part of the separation box 504. Several sliding beams 506 are installed on the set of guide rails 505. The second lead screw 502 is sequentially inserted into the middle of several sliding beams 506 and screwed to them. Several steel filter screens 507 are installed at the bottom of the sliding beams 506. The bottom ends of each steel filter screen 507 are rotatably connected to form a continuous filter belt.

[0052] Furthermore, the separation device also includes a drain port 508 located at the bottom of the cover 306. When the separation device is closed with the working chamber 201 of the tank 1 via the closing assembly, the drain port 508 is connected to the bottom of the working chamber 201.

[0053] Furthermore, the separation device also includes inclined baffles 509 installed on both sides of the separation tank 504, which, together with the separation tank 504, form a funnel shape for receiving sewage.

[0054] Furthermore, the locking mechanism includes an electric turntable 601 fixed to the top of the tank 1. The electric turntable 601 includes a rotary motor and a turntable. A buckle 602 is fixed to the front end of the turntable. A pin 603 is provided on the top of the cover 306. When the closing component drives the tank 1 to close with the tank 1, the electric turntable 601 rotates, causing the buckle 602 to rotate to the rear of the pin 603 on the top of the cover 306 and lock, thereby achieving the locking and sealing of the integrated classified sewage treatment tank.

[0055] Furthermore, the cleaning device includes a set of telescopic rods 702 fixed on the tank body 1 with a fixed cover. The front ends of the set of telescopic rods 702 are all connected to scrapers 701. The scrapers 701 are installed inside the tank body 1 and are flush with the inner surface of the tank body 1.

[0056] In practical use, the method of treating sewage using any of the above-described integrated classified sewage treatment tanks includes the following steps:

[0057] Step 1: After the integrated classified sewage treatment tank is installed in place, the buckle 602 of the clamping mechanism is initially positioned on the top surface of the tank body 1. Start the drive motor 303, which drives the first lead screw 304 to rotate, causing the baffle 305 that is screwed to it to move towards the tank body 1. The cover 306, which is fixed to the baffle 305, moves in the same direction. The separation device and pin 603, which are fixed to the cover 306, move in the same direction and synchronously until the cover 306 is pressed tightly against the side of the tank body 1.

[0058] Step 2: Start the rotary motor of the electric turntable 601 to drive the turntable to rotate. The turntable drives the buckle 602, which is fixed to it, to rotate to the rear of the top pin 603 of the cover 306, and lock it in place. At the same time, the integrated classified sewage treatment tank is locked and sealed.

[0059] Step 3: Start the servo motor 403 of the absorption device, which drives the drive gear 404 to rotate. The drive gear 404 drives the driven gear 405 to rotate, which in turn drives the rotating seat 406 to rotate. The rotation of the rotating seat 406 causes the water pumping pipe 407 to swing horizontally, facing the sewage source laterally. Start the hydraulic cylinder 408, which drives the hinge seat 409 to rotate. The hinge seat 409 drives the water pumping pipe 407 to align with the sewage source.

[0060] Step 4: Wastewater enters the separation device through the inlet 203. The stepper motor 501 is started and rotates, which drives the second lead screw 502 to rotate. The second lead screw 502 drives the slider beam 506 to move. The slider beam 506 drives the steel filter screen 507 to move, filtering the sludge in the wastewater. The water enters the tank 1 through the filter holes at the bottom of the steel filter screen 507 and the separation box 504 and is discharged through the drain port 508. At the same time, the slider beam 506 moves closer layer by layer, compressing the sludge left in the filter cloth into a cake shape.

[0061] Step 5: Start the rotary motor of the electric turntable 601. The rotary motor reverses and drives the turntable to rotate in the opposite direction. The turntable drives the buckle 602, which is fixed to it, to rotate to the top of the tank 1, separate from the pin 603, and release the closing assembly.

[0062] Step 6: Start the drive motor 303. The drive motor 303 reverses and drives the first lead screw 304 to rotate in the opposite direction. This causes the baffle 305, which is screwed to it, to move away from the tank body 1. The box cover 306, which is fixed to the baffle 305, moves away together with it. The separation device and pin 603, which are fixed to the box cover 306, move away synchronously in the same direction until the separation device is removed from the working chamber 201 of the tank body 1.

[0063] Step 7: Start the stepper motor 501. The stepper motor 501 rotates in the reverse direction, which drives the second lead screw 502 to rotate in the reverse direction. The second lead screw 502 drives the slider beam 506 to move in the reverse direction. The slider beam 506 drives the steel filter screen 507 to move in the reverse direction. Each layer of steel filter screen 507 unfolds and the cake-shaped sludge inside is removed.

[0064] Step 8: Repeat Step 2 to Step 3, open the three-way valve 302, start the vacuum pump 301, and introduce water into the top and bottom of the tank 1 to clean the working chamber of the tank 1. Start the telescopic pole 702, which pushes the scraper 701 to scrape the bottom of the working chamber 201 of the tank 1. The cleaned water is discharged through the drain port 508. Repeat Step 4 to Step 7 the next time you need to treat sewage.

[0065] In a preferred embodiment, the closing assembly includes a set of first lead screws 304 rotatably connected to two sets of mounting seats 202 at both ends of the tank body 1. One end of the first lead screw 304 is equipped with a drive motor 303, and the other end is rotatably mounted to the mounting seat 202. The middle part is screwed and rotatably connected to a baffle 305. One end of the baffle 305 is fixed to the lid 306. A set of brackets 307 is fixed to the bottom of the tank body 1. The above configuration enables the flexible opening and closing of the tank body 1 and the lid 306. The rotation of the first lead screw 304 is controlled by the forward and reverse rotation of the drive motor 303, thereby driving the baffle 305 and the lid 306 to move along the axial direction of the tank body 1 to complete the sealing and opening operations. The structure is compact and the operation is simple.

[0066] In a preferred embodiment, the closing assembly further includes a vacuum pump 301 fixed to a fixed cover plate of the tank 1. The outlet end of the vacuum pump 301 is connected to a three-way valve 302. One of the other two circuits of the three-way valve 302 is connected to the top of the tank 1, and the other is connected to the bottom of the tank 1 through a hole in the fixed cover plate. The above configuration allows for flexible vacuuming operations inside the tank 1, ensuring a stable internal environment. It also facilitates subsequent cleaning or maintenance of the tank interior, improving the overall flexibility and practicality of the equipment.

[0067] In a preferred embodiment, the absorption device includes a feed pipe 401 communicating with the feed inlet 203. The feed pipe 401 is fixed on a rotating base 406, which is rotatably mounted on the tank body 1 and communicating with the feed inlet 401. A driven gear 405 is mounted on the rotating base 406, meshing with a drive gear 404. The drive gear 404 is driven by a servo motor 403 and fixed to the top of the tank body 1 by a mounting plate 402. A hinge seat 409 is rotatably mounted on the top of the rotating base 406. A water suction pipe 407 is fixed on the seat 409, and the water suction pipe 407 is connected to the feed pipe 401. A hydraulic cylinder 408 is installed at the bottom of the hinge seat 409, and the other end of the hydraulic cylinder 408 is fixed on the rotating seat 406. The above configuration can realize the flexible rotation and lifting of the water suction pipe 407. The servo motor 403 controls the drive gear 404 to drive the driven gear 405 to rotate, thereby adjusting the feeding direction. The hydraulic cylinder 408 controls the lifting of the water suction pipe 407 to adapt to sewage sources of different heights, thereby improving absorption efficiency and flexibility.

[0068] In a preferred embodiment, the separation device includes a second lead screw 502 rotatably mounted on a box cover 306. A stepper motor 501 is mounted at one end of the second lead screw 502, and the other end is fixed to a separation box 504. One end of the separation box 504 is fixed to the box cover 306 via a connecting plate 503. The bottom of the separation box 504 is densely provided with filter holes. A set of guide rails 505 is mounted on both sides of the upper part of the separation box 504. Several sliding beams 506 are mounted on the guide rails 505. The second lead screw 502 is sequentially... A series of slide beams 506 are threaded through and screwed to each other. Several steel filter screens 507 are installed at the bottom of the slide beams 506. The bottom ends of each steel filter screen 507 are rotatably connected to form a continuous filter belt. With the above configuration, the second lead screw 502 rotates under the drive of the stepper motor 501, which drives the slide beams 506 and steel filter screens 507 to slide along the guide rail 505, realizing the continuous movement of the filter belt, effectively filtering impurities and discharging them, while maintaining the cleanliness and efficient separation effect in the separation box 504.

[0069] In a preferred embodiment, the separation device further includes a drain port 508 located at the bottom of the tank cover 306. When the separation device is closed with the working chamber 201 of the tank body 1 via the closing assembly, the drain port 508 is connected to the bottom of the working chamber 201. This configuration can effectively discharge the impurities and wastewater deposited in the working chamber 201, ensuring the continuous and efficient operation of the separation process. At the same time, the design of the drain port 508 facilitates regular cleaning and maintenance, improving the overall service life and reliability of the separation device.

[0070] In a preferred embodiment, the separation device further includes inclined baffles 509 installed on both sides of the separation tank 504, which, together with the separation tank 504, form a funnel shape for receiving sewage. The above arrangement can further ensure that sewage flows smoothly into the separation tank under the action of gravity, reduce splashing and side leakage, and improve the efficiency and cleanliness of sewage treatment. At the same time, the design of the inclined baffles 509 also helps to slow down the water flow speed and promote the sedimentation of impurities.

[0071] In a preferred embodiment, the locking mechanism includes an electric turntable 601 fixed to the top of the tank 1. The electric turntable 601 includes a rotary motor and a turntable.
