Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater purification suction truck. Background Technology

[0002] Wastewater treatment refers to the process of removing or degrading pollutants such as harmful substances, suspended solids, organic matter, and pathogens from domestic sewage, industrial wastewater, and other polluted water bodies using physical, chemical, and biological technologies and methods, thereby purifying the water to meet discharge standards or reuse requirements. Its purpose is to prevent water pollution, protect the aquatic environment, safeguard human health, and achieve the sustainable use of water resources.

[0003] In the wastewater treatment field, commonly used wastewater transfer equipment often only has a single suction and transfer function, requiring wastewater to be transported to fixed wastewater treatment plants for further treatment. This results in high transfer costs and low treatment efficiency. Meanwhile, some simple wastewater purification equipment suffers from insufficient filtration stages and poor purification effects, and lacks on-site integrated treatment capabilities, failing to meet the needs of emergency wastewater treatment (such as pipeline leaks and river dredging) and decentralized wastewater treatment. Furthermore, existing equipment generally suffers from strong dependence on power systems, susceptibility to site limitations, and inconvenient maintenance, making it difficult to adapt to wastewater purification operations under complex conditions.

[0004] Therefore, there is an urgent need for a sewage suction and purification vehicle for sewage purification. Summary of the Invention

[0005] In order to overcome the shortcomings of existing sewage transfer equipment, which mostly only have a single suction and transfer function and need to transport sewage to a fixed sewage treatment plant for subsequent treatment, resulting in high transfer costs, low treatment efficiency, insufficient filtration levels, poor purification effect, and lack of on-site integrated treatment capabilities, thus failing to meet the needs of emergency sewage treatment and decentralized sewage treatment, this invention provides a sewage purification suction and purification vehicle.

[0006] The technical solution of this invention is as follows: a sewage purification suction vehicle, comprising a tractor, a towing frame, a first suction pump, a conveying pipe, a coarse filter frame, a filter, a mixing frame, a discharge hopper, a second suction pump, a fine filter frame, a corrugated filter screen, a disinfection device, a control panel, a water outlet, and a stirring mechanism. A towing frame is fixedly connected to one side of the tractor, and the first suction pump is installed on the tractor. The output end of the first suction pump is connected to the conveying pipe, and a coarse filter frame is fixedly connected to the end of the conveying pipe away from the first suction pump. A filter is installed inside the coarse filter frame near the conveying pipe. The device has a coarse filter frame with a mixing frame fixedly connected to one side. A hopper is installed on the mixing frame, with one end of the hopper extending into the mixing frame. A stirring mechanism is installed inside the mixing frame. A fine filter frame is fixedly connected to the side of the mixing frame opposite to the coarse filter frame. A corrugated filter screen is fixedly connected inside the fine filter frame. A second suction pump is installed on the fine filter frame. The input end of the second suction pump is connected to the fine filter frame. The mixing frame is connected to both the fine filter frame and the coarse filter frame. The output end of the second suction pump is connected to a disinfection device through a connecting pipe. The disinfection device is equipped with a control panel and an outlet.

[0007] Furthermore, it also includes a spare tire, which is movably installed at the bottom of the tractor unit for replacing the tractor unit's wheels.

[0008] Furthermore, it also includes a generator, which is installed on the tractor. The generator is electrically connected to the suction pump 1, filter, suction pump 2, disinfection device and control panel.

[0009] Furthermore, the filter consists of a conical filter screen, a spiral filter plate, and a drive mechanism. When sewage enters the coarse filter frame, the filter can perform preliminary filtration of the sewage.

[0010] Furthermore, it also includes valves, with valves installed at the connection points between the mixing frame and the fine and coarse filter frames. The valves are electrically driven and electrically connected to the generator.

[0011] Furthermore, the mixing mechanism includes a servo motor, a mixing blade, and a discharge cylinder. The servo motor is installed at the bottom of the tractor and is electrically connected to the generator. The output shaft of the servo motor extends into the mixing frame and is connected to the mixing blade. The end of the mixing blade away from the servo motor is fixedly connected to the hopper. Multiple discharge cylinders are fixedly connected at even intervals around the bottom of the hopper, and multiple through holes are opened on the discharge cylinders.

[0012] Furthermore, it also includes a spring, a push block, a push rod, and a contact block. One end of the spring is fixedly connected to the inside of the discharge cylinder near the through hole. The end of the spring opposite to the discharge cylinder is fixedly connected to a push block that can slide in and out of the through hole of the discharge cylinder. A push rod is slidably connected to the discharge cylinder. A contact block is fixedly connected inside the mixing frame. During the rotation of the discharge cylinder, the push rod contacts the contact block.

[0013] Furthermore, it also includes a baffle, with a baffle fixedly connected inside the fine filter frame near the connection point with the mixing frame.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention realizes the on-site integrated treatment of sewage “sucking-coarse filtration-fine filtration-disinfection”, without the need to transport it to a fixed sewage treatment plant, which greatly reduces the sewage transportation cost and improves the treatment efficiency. It is especially suitable for emergency sewage treatment and decentralized sewage treatment scenarios.

[0015] 2. This invention achieves efficient mixing of wastewater and chemicals through the coordinated operation of components such as servo motors and stirring blades, improves mixing quality, effectively avoids uneven mixing of wastewater and chemicals, and promotes stable and efficient wastewater purification.

[0016] 3. This invention effectively removes large particulate impurities, suspended solids, and flocculent particles from wastewater through a multi-stage filtration structure of filters and corrugated filters, combined with a reagent mixing process, resulting in significant purification effects. At the same time, the spiral filter plate design of the filter can prevent filter clogging, and the corrugated filter improves fine filtration efficiency by increasing the filtration area.

Detailed Implementation

[0029] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0030] Example: A sewage suction and purification vehicle for sewage purification, such as Figures 1-11 As shown, the system includes a tractor 1, a tractor frame 2, a suction pump 5, a conveying pipe 6, a coarse filter frame 7, a filter 8, a valve 9, a mixing frame 10, a discharge hopper 11, a second suction pump 17, a fine filter frame 18, a corrugated filter screen 20, a disinfection device 21, a control panel 22, an outlet 23, and a mixing mechanism. The tractor 1 is fixedly connected to the tractor frame 2 on one side. The suction pump 5 is mounted on the tractor 1. The output end of the suction pump 5 is connected to the conveying pipe 6. The end of the conveying pipe 6 furthest from the suction pump 5 is fixedly connected to the coarse filter frame 7. A filter 8 is installed inside the coarse filter frame 7 near the conveying pipe 6. The filter 8 consists of a conical filter screen, a spiral filter plate, and a drive mechanism. When wastewater enters the coarse filter frame 7, the filter 8 performs preliminary filtration. The coarse filter frame 7 is fixedly connected to the... A mixing frame 10 is provided, and a hopper 11 is provided on the mixing frame 10. One end of the hopper 11 extends into the interior of the mixing frame 10. A stirring mechanism is provided inside the mixing frame 10. A fine filter frame 18 is fixedly connected to the side of the mixing frame 10 opposite to the coarse filter frame 7. A corrugated filter screen 20 is fixedly connected inside the fine filter frame 18. A second suction pump 17 is installed on the fine filter frame 18. The input end of the second suction pump 17 is connected to the fine filter frame 18. The mixing frame 10 is connected to both the fine filter frame 18 and the coarse filter frame 7. A valve 9 is provided at each connection point between the mixing frame 10 and the fine filter frame 18 and the coarse filter frame 7. The valve 9 is electrically driven and electrically connected to the generator 4. The output end of the second suction pump 17 is connected to a disinfection device 21 through a connecting pipe. The disinfection device 21 is provided with a control panel 22 and a water outlet 23.

[0031] like Figures 1-3 As shown, it also includes a spare tire 3. The bottom of the tractor 1 is movably provided with a spare tire 3 for replacing the wheels of the tractor 1. If the wheel of the tractor 1 fails, it can be removed by pushing the spare tire 3, and then the spare tire 3 can be replaced with the failed wheel, thereby ensuring the working endurance of the device.

[0032] like Figure 2 As shown, it also includes a generator 4. The generator 4 is installed on the tractor 1. The generator 4 is electrically connected to the suction pump 1 5, filter 8, suction pump 2 17, disinfection device 21 and control panel 22. The generator 4 serves as an independent power source. Combined with the mobility of the tractor 1, it eliminates the limitations of external power supply and site. It can operate flexibly in complex working conditions such as municipal pipelines, rivers, and industrial parks, and has strong adaptability.

[0033] like Figures 4-9 As shown, the stirring mechanism includes a servo motor 12, a stirring blade 13, and a discharge cylinder 14. The servo motor 12 is installed at the bottom of the tractor 1 and is electrically connected to the generator 4. The output shaft of the servo motor 12 extends into the mixing frame 10 and is connected to the stirring blade 13. The end of the stirring blade 13 away from the servo motor 12 is fixedly connected to the hopper 11. Multiple discharge cylinders 14 are fixedly connected at even intervals on the bottom periphery of the hopper 11. Multiple through holes are opened on the discharge cylinders 14. When the servo motor 12 is started, the servo motor 12 drives the output shaft to rotate. The output shaft of the servo motor 12 drives the stirring blade 13 to rotate. The stirring blade 13 drives the hopper 11 and the discharge cylinder 14 to rotate synchronously.

[0034] like Figures 7-9 As shown, it also includes a spring 141, a push block 142, a push rod 15, and a contact block 16. One end of the spring 141 is fixedly connected to the inside of the discharge cylinder 14 near the through hole. The end of the spring 141 opposite to the discharge cylinder 14 is fixedly connected to a push block 142 that can slide in and out of the through hole of the discharge cylinder 14. The push rod 15 is slidably connected to the discharge cylinder 14. The contact block 16 is fixedly connected to the inside of the mixing frame 10. During the rotation of the discharge cylinder 14, the push rod 15 periodically contacts the contact block 16 on the inner wall of the mixing frame 10. When in contact, the push rod 15 slides into the discharge cylinder 14. During the sliding process, the push rod 15 pushes the push block 142 at the discharge point. When the material cylinder 14 moves through the through hole, the spring 141 is compressed until the push rod 15 separates from the contact block 16. The push rod 15 is no longer affected by the force. At this time, the spring 141 returns to its original position by relying on its own characteristics. During the return process, the spring 141 applies a pushing force to the push block 142, causing the push block 142 to return to its initial position. During the reset process, the push block 142 squeezes the push rod 15, causing the push rod 15 to return to its initial position after being subjected to force. This process is repeated. By sliding the push block 142 in and out of the through hole of the discharge cylinder 14, the sediment generated by the mixing of the agent and the sewage can be effectively prevented from clogging the through hole of the discharge cylinder 14, ensuring the unobstructed flow of the through hole of the discharge cylinder 14.

[0035] like Figure 10 As shown, it also includes a baffle 19. The baffle 19 is fixedly connected inside the fine filter frame 18 near the connection with the mixing frame 10. The baffle 19 inside the fine filter frame 18 can prevent sewage from directly impacting the corrugated filter screen 20, extend the sewage flow path, promote full contact between sewage and the corrugated filter screen 20, and thus improve the filtration efficiency.

[0036] This device is used in wastewater purification and treatment. During operation, the generator 4 is started via control panel 22 to provide power to all users, ensuring all components are ready for operation. Then, the water pipe is connected to the input of the suction pump 5, allowing the pump to work in conjunction with the water pipe to extract wastewater. The wastewater to be treated flows from the output of the suction pump 5 and is pumped through the delivery pipe 6 connected to the pump 5 into the coarse filter frame 7. After the wastewater enters the coarse filter frame 7, the filter 8 is activated to intercept large particles (such as silt and suspended solids) in the wastewater, completing preliminary solid-liquid separation. Then, the valve 9 at the connection between the mixing frame 10 and the coarse filter frame 7 is opened, allowing the coarsely filtered wastewater to enter the mixing frame 7. Inside the mixing frame 10, after the coarsely filtered wastewater enters the mixing frame 10, an appropriate amount of treatment agent (such as flocculant) is added to the lower hopper 11. The agent enters the lower hopper 11 and flows into the discharge cylinder 14, passing through its through-hole and mixing with the wastewater. Simultaneously, the servo motor 12 is started, driving the output shaft to rotate. The output shaft of the servo motor 12 drives the stirring blade 13 to rotate, which in turn drives the lower hopper 11 and the discharge cylinder 14 to rotate synchronously. During the rotation of the discharge cylinder 14, the push rod 15 periodically contacts the contact block 16 on the inner wall of the mixing frame 10. Upon contact, the push rod 15 slides into the discharge cylinder 14, pushing the push block 142 to move at the through-hole of the discharge cylinder 14. Spring 141 is compressed until push rod 15 separates from contact block 16, and push rod 15 is no longer affected by the force. At this time, spring 141 returns to its original state based on its own characteristics. During the return process, spring 141 applies a pushing force to push block 142, causing push block 142 to return to its initial position. During the reset process, push block 142 squeezes push rod 15, causing push rod 15 to return to its initial position after being subjected to force. This process is repeated, and push block 142 slides in and out of the discharge cylinder 14 through hole, effectively preventing the sediment generated by the mixing of the agent and sewage from clogging the discharge cylinder 14 through hole, ensuring the unobstructed flow of the discharge cylinder 14 through hole. After the mixing is completed, valve 9 at the connection between mixing frame 10 and fine filter frame 18 is opened to allow the sewage containing flocculent particles to pass through. Water enters the fine filter frame 18. The baffle 19 inside the fine filter frame 18 can prevent sewage from directly impacting the corrugated filter screen 20, thereby improving filtration efficiency. Sewage flows along the baffle 19 to the corrugated filter screen 20. The corrugated filter screen 20 increases the contact area with sewage due to its own design structure, thereby increasing the filtration area and effectively intercepting flocculent particles and fine impurities in the sewage, realizing secondary solid-liquid separation. After the water is discharged, the suction pump 27 is started. The suction pump 27 pumps the finely filtered sewage to the disinfection device 21. The disinfection parameters (such as disinfection time) are set through the control panel 22. The disinfection device 21 sterilizes and disinfects the sewage. The treated sewage that meets the standards is discharged through the outlet 23, completing the entire sewage purification process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
