Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment equipment, and in particular relates to a sewage treatment equipment for flushing and treating the sewage of a bridge anti-collision wall during maintenance. Background Art

[0002] After the newly poured concrete anti-collision wall begins to set, it is necessary to spray water for maintenance in a timely manner. This is because concrete requires an appropriate amount of water during the hydration process to ensure the full hydration reaction of cement, thereby improving the strength and durability of the concrete. The sewage flowing down from the concrete anti-collision wall needs to be treated using treatment equipment. For example, a sewage treatment equipment for flushing and treating road maintenance pavement proposed in Patent Publication No. CN119143227A.

[0003] The sewage generated after the flushing and maintenance of the concrete anti-collision wall contains a large amount of sediment. After primary filtration, a flocculant needs to be added for deep treatment. Through the effects of compressing the double electric layer, adsorption bridging, etc., the flocculant promotes the aggregation of fine sediment particles in the sewage into clusters, forming flocs with a larger volume and a more compact structure, significantly accelerating the sedimentation rate. This process effectively improves the treatment efficiency of subsequent sedimentation and filtration processes, greatly reduces the turbidity of the sewage, and improves the effluent quality.

[0004] After the sediment has fully settled, it is necessary to pump out the supernatant. To avoid disturbing the bottom sediment and causing secondary turbidity, the pump needs to operate at a low power to reduce the 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, the sediment is easily attached and accumulated on the surface of the filter screen, causing blockage, resulting in a significant decrease in the extraction efficiency of the supernatant, which has become a key problem affecting the continuity and treatment effect of sewage treatment.

[0005] Therefore, a sewage treatment equipment for flushing and treating the sewage of a bridge anti-collision wall is proposed to solve the above problems. Summary of the Invention

[0036] The detection assembly 18 includes a detection cylinder 181 fixedly inserted into the side wall of the piston disc 10. There is an insertion plate 182 on the inner wall of the detection cylinder 181, and a plug rod 19 is inserted into the insertion plate 182. The lower end of the plug rod 19 is fixedly connected with a floating block 20. The lower end of the floating block 20 extends out of the detection cylinder 181.

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

[0037] The operating principle of the present invention is now explained as follows: before treating the sewage, the operator adds a certain amount of flocculant into the treatment barrel 3 through the feeding pipe 5, and the maintenance vehicle drives the treatment equipment to move to the bridge crash barrier area. When the maintenance vehicle flushes and maintains the crash barrier, the flushed sewage is collected by the collecting mechanism on the maintenance vehicle (in order to facilitate sewage collection, a drainage trough or a collection pipe can be set at the bottom of the crash barrier, and the sewage is first transported to the grille device on the maintenance vehicle through the collecting mechanism, and the larger solid debris in the sewage, such as leaves, branches, garbage, etc., is intercepted and removed through the grille, and then the sewage that has been initially filtered is transported to the treatment barrel 3 through the water inlet pipe 4). When all the collected sewage enters the treatment barrel 3 and the maintenance vehicle is driving, the operator can use the remote control device to The controller 2 transmits an electrical signal. After receiving the electrical signal, the controller 2 controls the first electric push rod 32 to work. The first electric push rod 32 drives the dust box 34 and the driving wheel 36 to move downward to a set distance through the support frame 33, so that the driving wheel 36 contacts the ground. During the driving of the maintenance vehicle, the driving wheel 36 drives the cross bar 35 to rotate through the friction between the driving wheel 36 and the ground. The cross bar 35 controls the rotation of the transmission rod 31 through the bevel gear transmission assembly. The transmission rod 31 drives the sealing plate 27 and the rotating tube 241 to rotate through the support plate 30, the guide cylinder 29 and the guide rod 28. The rotating tube 241 drives the hollow rotating disk 242 to rotate. The hollow rotating disk 242 drives the mixing drum 25 and the mixing plate 26 to rotate, so that the flocculant and the sewage can be stirred, and the combination of impurities and flocculants in the sewage can be accelerated.

[0038] Meanwhile, the controller 2 also controls the operation of the second electric push rod 44, causing the second electric push rod 44 to drive the extrusion wheel 45 to move downward to a set position. During the rotation of the rotating pipe 241, it drives the lower air supply disk 371 to rotate. The lower air supply disk 371 drives the upper air supply disk 38 to rotate through the mutual cooperation of the limiting cylinder 48 and the limiting frame 49. During the rotation of the upper air supply disk 38, it drives the triangular block 43 to rotate through the bracket. When the triangular block 43 rotates below the extrusion wheel 45, the extrusion wheel 45 squeezes the inclined surface of the triangular block 43, causing the triangular block 43 to drive the upper air supply disk 38 to move downward through the bracket. During the downward movement of the upper air supply disk 38, it compresses multiple telescopic tubes 372, enabling the gas inside the multiple telescopic tubes 372 to be transported above the sealing plate 27 in the rotating pipe 241 through the lower air supply disk 371 and the air supply pipe 39, and then transported into the hollow turntable 242 through the rotating pipe 241 and the first one-way valve 40, increasing the air pressure inside the hollow turntable 242. When the air pressure inside the hollow turntable 242 exceeds the threshold of the pressure valve 47, the gas inside the hollow turntable 242 is discharged into the sewage through multiple thin tubes 46, forming dense small bubbles. During the upward floating process of the small bubbles, they further stir the sewage and the flocculant. At the same time, the bubbles adhere to the surface of the grease in the sewage, causing the grease to rise to the liquid surface with the bubbles. When the triangular block 43 and the extrusion wheel 45 are separated, under the action of the spring elasticity, the upper air supply disk 38 moves upward, thereby reducing the gas inside the multiple telescopic tubes 372. Under the action of the atmospheric pressure, the external gas enters the telescopic tubes 372 through the air inlet pipe 41 and the second one-way valve 42. By adjusting the distance that the second electric push rod 44 drives the extrusion wheel 45 to move downward, the amount of bubbles transported into the sewage each time can be controlled, avoiding the problem that excessive bubbles may cause the bubbles to collide and merge with each other, reducing the contact opportunity with pollutants, and lowering the flotation efficiency;

[0039] After the stirring operation has been carried out for ten minutes, the controller 2 will control the first electric push rod 32 to drive the driving wheel 36 to move upward and separate from the ground, and control the second electric push rod 44 to drive the extrusion wheel 45 to move upward to the initial position. After the maintenance vehicle has stopped running for half an hour, sludge and other sundries in the sewage will settle below the sewage under the action of the flocculant. The controller 2 will control the lead screw linear module 7 to work, and use the lead screw linear module 7 to drive the lifting frame 9, the water suction pipe 61 and the elbow pipe 62 to move downward together. During the downward movement of the water suction pipe 61 and the elbow pipe 62, the controller 2 will also control the external extraction component (the extraction component consists of a pipeline and a pump) communicated with the elbow pipe 62 to work, so that the air pressure inside the elbow pipe 62 is reduced. During the downward movement of the water suction pipe 61 and the elbow pipe 62, they will drive the piston disc 10 and the oil suction disc 16 to move downward together. During the downward movement of the oil suction disc 16, it will contact the oil stain on the surface of the supernatant. The oil suction disc 16 will extract the oil stain through the oil suction head 17, so that the oil stain is discharged from the treatment cylinder 3 through the elbow pipe 62. And when the oil suction disc 16 contacts the oil stain, the lower end of the floating block 20 will also contact the oil stain. Since the density of the floating block 20 is greater than the density of the oil stain and less than the density of water, the floating block 20 will move downward in the oil stain. When the floating block 20 contacts the supernatant, the floating block 20 will float on the supernatant. And during the process of the piston disc 10 driving the detection cylinder 181 to move downward, the floating block 20 will drive the lifting plate 21 and the conductive block 22 to move relatively upward in the detection cylinder 181 through the insertion rod 19, so that the conductive block 22 contacts the conductive plate 23. The conductive block 22 is electrically connected to the external power supply through the conductive slide plate assembly, and the conductive plate 23 is electrically connected to the controller 2. When the two contact, the conductive plate 23 will transmit an electric signal to the controller 2. After receiving this electric signal, the controller 2 will control the extraction component communicated with the elbow pipe 62 to stop working, and control the extraction component communicated with the water suction pipe 61 to work;

[0040] The extraction component will extract the gas inside the water suction pipe 61, reducing the air pressure inside the water suction pipe 61. At the same time, the controller 2 will also control the lead screw linear module 7 to continue working. The lead screw linear module 7 will drive the water suction pipe 61 and the piston disk 10 to move downward quickly together. The supernatant will flow through the filter holes 11 and the filter net 12 to the upper part of the piston disk 10, and be transported into the water suction pipe 61 through the annular pipe 13, the water suction head 14 and the short pipe 15, and be discharged through the extraction component. When the piston disk 10 moves above the flocculated sludge below, since the sludge cannot pass through the filter net 12, the piston disk 10 will be subject to a large resistance. This resistance will be transmitted to the tension sensor 8 through the piston disk 10, the water 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 extract the supernatant completely. When the operator sees that the extraction component no longer drains water outdoors, it means that the extraction of the supernatant has been completed. 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.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
