Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation vehicles, in particular to a mobile dual-purpose soil mud solid-liquid separation vehicle. Background Art

[0002] With the rapid economic development and the massive discharge of wastewater, heavy metal pollution in soil and water sources has become increasingly serious. Currently, heavy metal-contaminated soil is mostly treated by leaching. The heavy metal ions leached from the soil are eventually enriched in the leaching waste liquid. The leaching waste liquid is reused as circulating water for soil leaching after water treatment. The bottom mud in the wastewater after water treatment is filtered and separated and precipitated to be discharged as mud cake. The mud cake separated from this wastewater is generally treated as hazardous waste and entrusted to qualified units for disposal. Soil slurry is formed after soil leaching, and the mud cake filtered out is usually clean soil, which can be directly backfilled.

[0003] When using traditional filtering equipment for soil cleaning, there will be single functions, long and scattered production lines, complex pipelines in the middle links, and easy leakage. The mobile dual-purpose soil mud solid-liquid separation vehicle provided by the utility model can achieve the advantages of highly integrated equipment, quick installation, and excellent on-site operating environment.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please see attached Figure 1 - Attachment Figure 3 The utility model provides an embodiment: a mobile dual-purpose soil slurry solid-liquid separation vehicle, comprising a frame 1, an upper platform 2 is arranged at the front of the frame 1, a conveyor 4 and a large filter press 3 are arranged at the rear of the frame 1, a main conveying pipeline 12 and a filtrate temporary storage box 17 are arranged in the middle of the frame 1, a lifting device 16 is arranged below the frame 1, a small water tank 10 and a large water tank 11 are arranged in the upper platform 2, a small filter press 8 is installed above the small water tank 10, the large water tank 11 is connected to the large filter press 3 through the main conveying pipeline 12, the drainage nozzle of the large filter press 3 is connected to the filtrate temporary storage box 17, the conveyor 4 is connected below the large filter press 3, and a folding corridor 6 is arranged on both sides of the large filter press 3, a folding guardrail 7 is arranged above the folding corridor 6, and a diagonal support rod 5 is arranged below.

[0028] Specifically, a conveyor 4 and a large filter press 3 are arranged at the rear of the frame 1. The conveyor 4 is responsible for conveying materials, and the large filter press 3 is responsible for filtering materials. The combined action of the conveyor 4 and the large filter press 3 ensures that materials can flow smoothly between various components. The large filter press 3 separates the contaminated soil into filtrate and clean soil, and the filtrate temporary storage box 17 is used to store the filtrate after disposal for subsequent disposal. A lifting device 16 is also installed under the frame 1. The lifting device 16 can adjust the height of the entire device as needed to adapt to different working environments.

[0029] Please see attached Figure 4 - Attachment Figure 5 A slider 13 is provided at the bottom of the small filter press 8, and the slider 13 is placed on the universal roller 14 inside the slideway 9. The folding corridor 6 can be folded downward, and the folding guardrail 7 can be folded upward. The working and unloading positions of the small filter press 8 are not the same. When working, it is placed above the small water tank 10, and when unloading, it is placed outside the small water tank 10. The drainage nozzle of the small filter press 8 is connected to the filtrate temporary storage box 17, and the small water tank 10 is connected to the small filter press 8 through the auxiliary conveying pipeline 15;

[0030] Specifically, the design of the small filter press 8 takes flexibility and functionality into consideration. In order to ensure the convenience of its movement, the bottom of the small filter press 8 is specially equipped with a slider 13, which is arranged inside the slide 9. The universal roller 14 in the slide 9 enables the small filter press 8 to move easily in all directions, greatly enhancing the flexibility of operation. The folding guardrail 7 can also be folded upward, which increases the safety during work and also provides additional convenience. When it is not needed, the folding guardrail 7 can be folded up.

[0031] Working principle: Usually two kinds of mud with different properties can be filtered. The soil mud first enters the large water tank 11 for buffering, and then enters the large filter press 3 through the main conveying pipeline 12 by the filter press pump. The large filter press 3 separates the incoming material into filtrate and clean soil. The clean soil is discharged through the conveyor 4, and the clean soil can be used as soil backfill; the filtrate is discharged into the filtrate temporary storage box 17 and then discharged into the back-end process water treatment device by the pump. The water treatment device is not the integrated equipment of the mobile dual-purpose soil mud solid-liquid separation vehicle of this invention. The water treatment device is a conventional equipment in this field. After the water treatment device treats the filtrate, it enters the small The water is buffered in the water tank 10, and then enters the small filter press 8 through the auxiliary delivery pipeline 15 by the filter press pump. The small filter press 8 separates the incoming materials into recycled water and mud cake. The small filter press 8 is placed above the small water tank 10 during the filtration process. After reaching the unloading standard, the hydraulic cylinder pushes the small filter press 8 out of the small water tank 10 for unloading. After unloading, the cylinder retracts and returns to the working state. During the pushing and returning process, the slider 13 at the bottom of the small filter press 8 rolls on the universal roller 14 inside the slide 9, and the operation is stable and smooth. The folding corridor 6 and the folding guardrail 7 can be folded once and fixed on both sides of the vehicle body. The recycled water can be used for soil leaching after treatment, and the mud cake needs to be disposed of by a qualified unit.

[0032] The utility model has two purposes in one vehicle. The large filter press 3 can be used to wash the soil to form clean soil, and the small filter press 8 can be used to form mud cake after treatment. The utility model has complete functions. The small filter press 8 can unload materials outside the vehicle body, and the cleaning work is more convenient. At the same time, the whole vehicle can be quickly installed and can be directly put into place to perform solid-liquid separation work.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
