Abstract
Description
Technical Field
[0001] This utility model relates to the field of water filtration devices, specifically to a water filtration device for a guardrail cleaning vehicle. Background Technology
[0002] The water filtration device of the guardrail cleaning truck is an environmentally friendly device specially designed to treat the wastewater generated during the cleaning process and realize the recycling of water resources. It purifies the wastewater containing impurities such as mud, oil, and rust and reuses it for cleaning operations.
[0003] Existing water filtration devices effectively separate particulate impurities from wastewater through filter screens, enabling the purified water to be recycled. However, in actual operation, as the continuous working time increases, particulate impurities inevitably accumulate on the surface of the filter screen. This blockage not only reduces the system's filtration efficiency and water flow, but also leads to a series of reactions such as increased working pressure and energy consumption. Frequent filter screen cleaning and maintenance not only increases the additional manual operation burden, but also interrupts the normal cleaning process, affecting the overall work efficiency of guardrail cleaning. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a water filtration device for a guardrail cleaning vehicle, thereby solving the aforementioned technical problems.

[0018] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0019] Example 1: like Figures 1 to 4 As shown, this utility model provides a water filtration device for a guardrail cleaning vehicle, including a housing 1, a sewage inlet 2 on the housing 1, a water outlet 3 at the bottom of the housing 1, and an impurity discharge outlet 4 on the side wall of the housing 1, and further including: The filter screen 5 is installed inside the housing 1. The side wall of the filter screen 5 is connected to the sewage inlet 2. The filter screen 5 is used to initially filter large particulate impurities in the sewage. The fine filtration component is housed in the housing 1. A filter cloth 6 is connected to the output end of the fine filtration component. The fine filtration component drives the filter cloth 6 to move around the filter screen 5 in the circumferential direction to further filter the sewage that has passed through the filter screen 5. The spray assembly is disposed inside the housing 1 and above the filter cloth 6. The spray assembly is used to rinse fine particles on the filter cloth 6. The recovery plate 7 is disposed inside the housing 1 and above the filter screen 5. The recovery plate 7 is used to collect fine particles on the filter cloth 6. A pushing component is disposed on the housing 1. The output end of the pushing component abuts against the upper surface of the recycling plate 7. The output end of the pushing component moves along the upper surface of the recycling plate 7 to push the impurities on the upper surface of the recycling plate 7 out of the housing 1.
[0020] In use, wastewater enters through the wastewater inlet 2 of the housing 1 and first flows through the filter screen 5 for preliminary filtration, where large particles are intercepted. The wastewater after preliminary filtration passes through the filter screen 5 and enters the fine filtration component area. The fine filtration component drives the filter cloth 6 to circulate along the outer ring of the filter screen 5, further trapping fine particles in the water on the surface of the filter cloth 6. The spray component sprays water from above onto the moving filter cloth 6, washing the fine particles accumulated on the filter cloth 6 onto the recovery plate 7 below. The push component pushes the impurities accumulated on the recovery plate 7 toward the impurity discharge outlet 4 on the side wall of the housing 1 for discharge, while the filtered clean water flows out from the outlet 3 at the bottom of the housing 1.
[0021] Example 2: like Figures 1 to 4 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the fine filtration assembly includes two drive motors 8, both of which are fixedly mounted on the outer wall of the housing 1. Drive shafts 9 are fixedly mounted on the output ends of both drive motors 8. Both drive shafts 9 pass through one side of the wall of the housing 1 and extend to the other side of the wall. Both drive shafts 9 are rotatably connected to the housing 1. Two driven shafts 10 are rotatably mounted on the inner wall of the housing 1. The two driven shafts 10 correspond one-to-one with the two drive shafts 9 and are arranged parallel to each other. Filter cloth 6 is sleeved on the outside of the two drive shafts 9 and the two driven shafts 10. The output shafts of the drive motors 8 and the two driven shafts 10 inside the housing 1 together form a circumferential motion path, sleeved on the outside of the four shafts. When the drive motors 8 rotate, they drive the filter cloth 6 to move cyclically, filtering wastewater while transferring the dirty parts to the spray area for cleaning, thus achieving uninterrupted filtration.
[0022] Furthermore, the spray assembly includes several spray pipes 11, each with a uniform array of spray holes 12, and each spray pipe 11 is connected to a clean water pipe 13. Clean water is delivered to the multiple spray pipes 11 through the clean water pipes 13 and sprayed evenly through the spray holes 12 on the spray pipes 11, fully covering the filter cloth 6 below, washing away any remaining fine impurities on the filter cloth 6, and ensuring that the filter cloth 6 continuously and efficiently filters sewage.
[0023] Furthermore, the recovery plate 7 is fixedly installed on the inner wall of the housing 1, and the upper surface of the recovery plate 7 is flush with the bottom of the impurity discharge port 4. When the spray water washes the dirt off the filter cloth 6, the recovery plate 7 catches these impurities. Due to the high alignment, the pushing component can push the accumulated impurities directly out of the discharge port without jamming or leaving any residue.
[0024] Furthermore, the pushing component includes an output motor 14, which is fixedly mounted on the outer wall of the housing 1. A screw 15 is fixedly mounted on the output end of the output motor 14. The screw 15 passes through one side of the wall of the housing 1 and extends to the other side of the wall. A connecting block 16 is threadedly connected to the outer side of the screw 15. A push plate 17 is fixedly connected to one end of the connecting block 16. The push plate 17 abuts against the upper surface of the recycling plate 7. After the output motor 14 is started, it drives the screw 15 to rotate. The connecting block 16 is sleeved on the screw 15. As the screw 15 rotates, the connecting block 16 will move back and forth along the surface of the recycling plate 7 with the push plate 17. The push plate 17 is always in close contact with the recycling plate 7, pushing out the accumulated impurities.
[0025] Furthermore, a guide rod 18 is fixedly installed on the inner wall of the housing 1, and a guide block 19 is slidably connected to the outer side of the guide rod 18. One end of the guide block 19 is fixedly connected to the push plate 17. The guide block 19 slides on the guide rod 18 and is fixedly connected to the push plate 17. When the push plate 17 moves back and forth, the guide block 19 slides smoothly along the guide rod 18 to ensure the stability of the movement path of the push plate 17.
[0026] Furthermore, there are two sewage inlets 2, each with a sewage pipe 20 fixedly installed. This dual-channel design allows sewage to enter the filtration system quickly and evenly, improving the influent efficiency.
[0027] Furthermore, the water outlet 3 is located on the side wall of the housing 1 and below the filter cloth 6, and a water outlet pipe 21 is connected to the water outlet 3. The location of the water outlet 3 below the side wall ensures that the filtered water is discharged smoothly without affecting the normal operation of the upper filtration system.
[0028] Furthermore, a collection frame 22 is fixedly installed on the outer wall of the housing 1, and the collection frame 22 is located below the impurity discharge port 4. The push plate 17 pushes the impurities on the recovery plate 7 out of the discharge port, and these impurities fall into the collection frame 22 located directly below the outer wall of the housing 1.
[0029] The working principle of the water filtration device for a guardrail cleaning vehicle disclosed in this application is as follows: In use, wastewater enters the housing 1 through two wastewater inlets 2. It first passes through the filter screen 5 to initially intercept large particles of impurities. The water after initial filtration flows to the fine filtration component. This component drives the drive shaft 9 to rotate through two drive motors 8, causing the filter cloth 6, which is sleeved on the drive shaft 9 and the driven shaft 10, to move cyclically and perform fine filtration of the wastewater. The spray component above sprays water onto the filter cloth 6 through multiple spray pipes 11 with spray holes 12, washing the fine impurities accumulated on the filter cloth 6 onto the fixedly installed recovery plate 7. The push component drives the screw 15 to rotate through the output motor 14, causing the connecting block 16 to push the push plate 17 to move along the recovery plate 7, pushing the impurities out from the impurity discharge port 4, which is flush with the recovery plate 7, and into the collection frame 22 below. The filtered clean water is discharged from the outlet 3 on the side wall of the housing 1 through the outlet pipe 21.
[0030] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
