Description

Technical Field

[0001] This invention belongs to the technical field of sewage treatment equipment, and in particular relates to a flushing sewage treatment device for the maintenance of bridge crash barriers. Background Technology

[0002] Newly poured concrete crash barriers need to be sprayed with water for curing after initial setting. This is because concrete requires an appropriate amount of water during the hydration process to ensure the cement fully hydrates, thereby improving the strength and durability of the concrete. Wastewater flowing down from the concrete crash barrier needs to be treated using treatment equipment. For example, a road maintenance road surface washing wastewater treatment device is proposed in patent publication number CN119143227A.

[0003] Wastewater generated after the curing and washing of concrete crash barriers contains a large amount of silt. After initial filtration, flocculants need to be added for further treatment. Through compression of the double electric layer and adsorption bridging, the flocculants promote the aggregation of fine silt particles in the wastewater into larger and more compact flocs, which significantly accelerates the settling rate. This process effectively improves the treatment efficiency of subsequent sedimentation and filtration processes, greatly reduces the turbidity of the wastewater, and improves the quality of the effluent.

[0004] After the silt has settled sufficiently, the supernatant needs to be extracted using a pump. To avoid disturbing the bottom silt and causing secondary turbidity, the pump needs to be operated at low power to reduce water flow scouring. At the same time, a filter screen is installed at the end of the suction pipe to further intercept residual impurities. However, silt easily adheres to and accumulates on the surface of the filter screen, causing blockage and resulting in a significant decrease in the supernatant extraction efficiency, which has become a key issue affecting the continuity and effectiveness of wastewater treatment.

[0005] To address these issues, a wastewater treatment device for bridge crash barrier maintenance is proposed. Summary of the Invention

[0018] Compared with existing technologies, the advantages of a wastewater treatment device for bridge crash barrier maintenance are:

[0019] 1. By using the absorption components, when the supernatant in the treatment equipment is extracted by the external pump mechanism, the supernatant can be extracted very quickly. This avoids the problem of the pump mechanism extracting too fast, which would disturb the bottom sediment and cause secondary turbidity, as well as the problem of the sediment being accidentally discharged. It also avoids the problem of sediment clogging the absorption end of the pump mechanism, thus ensuring the working efficiency of the sewage treatment device.

[0020] 2. Through the set mixing and air supply components, the kinetic energy of the vehicle can be converted into the mixing power of the treatment drum during the operation of the maintenance vehicle. Through continuous and efficient mixing, the wastewater and flocculant are significantly accelerated to fully mix, greatly improving the flocculation reaction efficiency. At the same time, small bubbles can be automatically discharged into the wastewater, which makes the oil in the wastewater float on the surface of the wastewater, making it easier to clean the oil in the future.

[0021] 3. With the addition of absorption and detection components, the device employs a layered, progressive extraction technology when extracting surface oil from wastewater. This rapidly peels off the oil layer from top to bottom. When the extraction end approaches the surface of the supernatant, it can accurately identify changes in liquid level and immediately trigger an automatic shutdown mechanism. This effectively prevents the supernatant from mixing with the oil, achieving efficient separation of the two and significantly improving the purity and processing efficiency of oil recovery.

The conductive plate 23 is electrically connected to the controller 2 and can detect the interface between oil and supernatant.

[0037] The operating principle of this invention is explained as follows: Before treating the wastewater, the operator adds a certain amount of flocculant to the treatment cylinder 3 through the feeding pipe 5. The maintenance vehicle moves the treatment equipment to the bridge crash barrier area. While the maintenance vehicle is washing and maintaining the crash barrier, the wastewater washed down is collected by the collection mechanism on the maintenance vehicle (to facilitate wastewater collection, a drainage ditch or collection pipe can be installed at the bottom of the crash barrier. The wastewater is first transported to the grating device on the maintenance vehicle through the collection mechanism. The grating intercepts and removes larger solid debris, such as leaves, branches, and garbage, from the wastewater. Then, the wastewater that has undergone initial filtration is transported to the treatment cylinder 3 through the inlet pipe 4). When all the collected wastewater enters the treatment cylinder 3, and while the maintenance vehicle is moving, the operator can remotely control the equipment to... Controller 2 sends an electrical signal. Upon receiving the signal, controller 2 controls the first electric push rod 32 to operate. The first electric push rod 32 moves the dustproof box 34 and the drive wheel 36 downwards to a set distance via the support frame 33, so that the drive wheel 36 contacts the ground. During the operation of the maintenance vehicle, the drive wheel 36 rotates due to friction between it and the ground. The crossbar 35 rotates via the bevel gear transmission assembly. The transmission rod 31 rotates via the support plate 30, guide cylinder 29, and guide rod 28, which in turn rotates the sealing plate 27 and the rotating pipe 241. The rotating pipe 241 rotates the hollow turntable 242. The hollow turntable 242 rotates the mixing drum 25 and the mixing plate 26, thereby stirring the flocculant and wastewater and accelerating the combination of impurities and flocculant in the wastewater.

[0038] Simultaneously, controller 2 also controls the second electric push rod 44 to operate, causing the second electric push rod 44 to drive the extrusion wheel 45 downward to the set position. During the rotation of the rotating pipe 241, it will drive the lower air supply plate 371 to rotate. The lower air supply plate 371 drives the upper air supply plate 38 to rotate through the cooperation of the limiting cylinder 48 and the limiting frame 49. During the rotation of the upper air supply plate 38, it will drive the triangular block 43 to rotate through the bracket. When the triangular block 43 rotates to below the extrusion wheel 45, the extrusion wheel 45 will squeeze the inclined surface of the triangular block 43, causing the triangular block 43 to drive the upper air supply plate 38 downward through the bracket. During the downward movement of the upper air supply plate 38, it will compress multiple telescopic pipes 372, so that the gas inside the multiple telescopic pipes 372 is transported through the lower air supply plate 371 and the air supply pipe 39 to the upper part of the sealing plate 27 inside the rotating pipe 241, and then through the rotating pipe 241 and the first one-way valve 40 to the hollow rotating plate 242, so that the gas inside the hollow rotating plate 242 is transported to the upper part of the sealing plate 27 inside the rotating pipe 241. As the internal air pressure increases, when the internal air pressure of the hollow rotary table 242 exceeds the threshold of the pressure valve 47, the gas inside the hollow rotary table 242 will be discharged into the wastewater through multiple thin tubes 46, forming dense small bubbles. As the small bubbles rise, they will further agitate the wastewater and flocculant. At the same time, the bubbles will adhere to the surface of the grease in the wastewater, causing the grease to rise to the liquid surface with the bubbles. When the triangular block 43 and the squeezing wheel 45 separate, the upper air supply plate 38 will move upward under the action of the spring force, thereby reducing the gas inside the multiple telescopic tubes 372. Under the action of atmospheric pressure, the external gas will enter the telescopic tubes 372 through the air inlet pipe 41 and the second one-way valve 42. By adjusting the distance that the squeezing wheel 45 moves downward driven by the second electric push rod 44, the amount of bubbles delivered to the wastewater at one time can be controlled, avoiding the problem that too many bubbles may collide and merge with each other, reducing the chance of contact with pollutants and reducing flotation efficiency.

[0039] After ten minutes of mixing, controller 2 will control the first electric push rod 32 to move the drive wheel 36 upwards to separate from the ground, and control the second electric push rod 44 to move the extrusion wheel 45 upwards to the initial position. After the maintenance vehicle stops for half an hour, sludge and other debris in the wastewater will settle below the wastewater under the action of the flocculant. Controller 2 will then control the linear screw module 7 to work, using it to move the lifting frame 9, suction pipe 61, and bend 62 downwards together. During the downward movement of suction pipe 61 and bend 62, controller 2 will also control the external extraction component connected to bend 62 (the extraction component consists of pipes and a pump) to work, reducing the internal air pressure of bend 62. As suction pipe 61 and bend 62 move downwards, they will also move the piston disc 10 and oil suction disc 16 downwards together. During the downward movement of oil suction disc 16, it will come into contact with the oil on the surface of the supernatant. The oil suction disc 16, through the oil suction head 1... 7. The oil is extracted and discharged from the treatment cylinder 3 through the bend pipe 62. When the oil suction plate 16 comes into contact with the oil, the lower end of the float 20 also comes into contact with the oil. Since the density of the float 20 is greater than that of the oil and less than that of water, the float 20 will move downward in the oil. When the float 20 comes into contact with the supernatant, the float 20 will float on the supernatant. During the process of the piston plate 10 driving the detection cylinder 181 to move downward, the float 20 will drive the lifting plate 21 and the conductive block 22 to move upward relative to each other in the detection cylinder 181 through the insertion rod 19, so that the conductive block 22 and the conductive plate 23 come into contact. The conductive block 22 is electrically connected to the external power supply through the conductive slide assembly, and the conductive plate 23 is electrically connected to the controller 2. When the two come into contact, the conductive plate 23 will send an electrical signal to the controller 2. After receiving the electrical signal, the controller 2 will control the extraction component connected to the bend pipe 62 to stop working and control the extraction component connected to the suction pipe 61 to work.

[0040] The extraction assembly extracts the gas inside the suction pipe 61, reducing the internal pressure. Simultaneously, the controller 2 controls the linear screw module 7 to continue operating, causing the suction pipe 61 and piston disc 10 to move rapidly downwards. The supernatant flows through the filter holes 11 and filter screen 12 to the top of the piston disc 10, and is then transported back into the suction pipe 61 via the ring pipe 13, suction head 14, and short pipe 15, before being discharged through the extraction assembly. When the piston disc 10 moves above the flocculated sludge below, the sludge cannot pass through the filter screen 12. The piston disc 10 will experience significant resistance, which will be transmitted to the tension sensor 8 through the piston disc 10, the suction pipe 61, and the lifting frame 9. After the controller 2 detects this situation through the tension sensor 8, it will immediately control the lead screw linear module 7 to stop working, separating the supernatant from the sludge. The external extraction component can quickly and completely extract the supernatant. When the operator sees that the extraction component is no longer draining water, it means that the supernatant has been extracted completely. The operator can then turn off the extraction component and open the cover plate 50 to clean the remaining sludge inside the treatment cylinder 3.
