Technical Field

[0001] This utility model relates to the field of wastewater recycling and treatment technology, specifically a solid-liquid separation device for wastewater from a mining sand washing machine. Background Technology

[0002] During ore mining and sand and gravel screening, a large amount of water is used to wash and separate impurities from the ore, resulting in a large amount of wastewater containing mud, fine powder and harmful substances. Traditional wastewater treatment methods often involve multi-stage filtration of wastewater using multiple filters with different mesh sizes. However, multi-stage filtration suffers from high energy consumption, unsatisfactory treatment results, and water waste. Especially in an environment of increasingly scarce water resources, how to achieve wastewater recycling and solid-liquid separation has become a pressing technical challenge for the mining industry.

[0003] To address the aforementioned problems, we propose a solid-liquid separation device for wastewater from mining sand washing machines. Utility Model Content

[0020] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0021] Example: Refer to Figures 1-3 As shown, a solid-liquid separation device for wastewater from a sand washing machine in this embodiment includes a pretreatment cylinder 1 and a sedimentation tank 9. A crushing assembly is provided at the upper inner side of the pretreatment cylinder 1, including two sets of crushing rollers 3 that rotate relative to each other. A stirring chamber 4 is provided at the bottom inner side of the pretreatment cylinder 1. A stirring assembly is provided in the middle inner side of the stirring chamber 4, including a stirring shaft 5. The stirring shaft 5 is rotatably installed at the bottom inner side of the pretreatment cylinder 1 and is driven by a first motor 7. Multiple sets of stirring rods 6 are installed on both sides of the upper end of the stirring shaft 5.

[0022] The crushing component can crush the sand and gravel contained in the wastewater, and then the agitation component can agitate it, thereby effectively enhancing the efficiency and quality of the reaction between the wastewater, crushed stone and chemical agents.

[0023] A filter module 10 is installed in the middle of the inner side of the sedimentation tank 9. A mounting base 11 is set at the left end of the inner side of the sedimentation tank 9. A collection box 12 is placed in the middle of the inner side of the mounting base 11. The collection box 12 is located to the left of the filter module 10. The filter module 10 adopts existing filtration equipment, which mainly includes a multi-layer filtration structure to achieve high-quality filtration of wastewater. The setting of the filter module 10 allows the wastewater put into the sedimentation tank 9 to be filtered, preventing gravel and sludge from entering the right side of the inner cavity of the sedimentation tank 9. Under the action of the filter module 10, gravel and sludge settle in the collection box 12, providing convenience for subsequent cleaning work.

[0024] A hoisting assembly is provided at the upper middle part of the mounting base 11. The hoisting assembly is used to drive the mounting base 11 to move up and down. The hoisting assembly includes two sets of connecting rods 13, which are located on the upper sides of both ends of the mounting base 11. The top of the connecting rods 13 is provided with a lifting ring 14. A winding wheel 17 is installed on the upper left side of the sedimentation tank 9. The winding wheel 17 is driven by a second motor 18. The winding wheel 17 is connected to the two sets of lifting rings 14 by a steel wire rope. When it is necessary to lift the mounting base 11, the steel wire rope on the winding wheel 17 needs to be fixedly connected to the two sets of lifting rings 14. Then, the steel wire rope is wound up by the winding wheel 17, thereby realizing the lifting work of the mounting base 11.

[0025] Limiting grooves 15 are provided at the middle of both ends of the mounting base 11. The limiting grooves 15 are installed in the inner wall of the sedimentation tank 9. Limiting sliders 16 are installed on the back of the connecting rod 13. The limiting sliders 16 are slidably installed in the middle of the inner side of the limiting grooves 15. The setting of the limiting sliders 16 and the limiting grooves 15 is to limit the lifting and lowering movement of the mounting base 11, thereby effectively enhancing the stability of the mounting base 11 when it is lifting and sliding.

[0026] In some examples, a feed hopper 2 is provided at the top of the pretreatment cylinder 1. The feed hopper 2 is located at the top of the two sets of crushing rollers 3. The feed hopper 2 mainly guides the wastewater to the space between the two sets of crushing rollers 3, so that the crushing rollers 3 can uniformly crush the stones of different sizes. By crushing the stones and reducing their volume, the stones can be fully mixed with the chemical agents, thereby enhancing the efficiency and quality of the reaction between the stones and the chemical agents.

[0027] In some examples, the pretreatment cylinder 1 and the sedimentation tank 9 are connected by a connecting pipe 8, and a valve is provided in the middle of the connecting pipe 8. Opening the valve allows the wastewater in the pretreatment cylinder 1 to be discharged into the sedimentation tank 9 for sedimentation and filtration treatment.

[0028] In some examples, a discharge pipe 19 is provided at the bottom right end of the sedimentation tank 9 for discharging the wastewater after sedimentation and filtration.

[0029] In some examples, the first motor 7 is fixedly mounted at the bottom center of the pretreatment cylinder 1.

[0030] The working principle of this utility model is as follows:

[0031] During operation, wastewater is first fed into the feed hopper 2 through a pipeline. Guided by the feed hopper 2, the wastewater falls into the crushing assembly. While feeding the wastewater, chemical agents are also added through the feed hopper 2 to treat the wastewater. As the wastewater flows downward, two sets of crushing rollers 3 rotate relative to each other, crushing the sand and gravel contained in the wastewater. All the gravel of different sizes is crushed into fine sand-like particles, which then fall into the mixing chamber 4 below. At this time, the first motor 7 is activated, which drives the stirring shaft 5 to rotate, thereby driving multiple sets of stirring rods 6 to rotate in the mixing chamber 4. This stirs the gravel and wastewater in the mixing chamber 4, ensuring that the wastewater, gravel, and chemicals are fully mixed, thus improving the efficiency of the chemical reaction.

[0032] After the wastewater is treated, the connecting pipe 8 is opened, allowing the wastewater to flow into the sedimentation tank 9 for sedimentation. The settled water then flows through the filter module 10 into the inner right end of the sedimentation tank 9 and is finally discharged through the discharge pipe 19.

[0033] The sediment and silt that settle and filter out will fall into the collection box 12 for centralized collection, thus facilitating the cleaning work of the staff. The cleaning process is as follows: First, the staff starts the second motor 18 to drive the winding wheel 17 to rotate, thereby winding up the steel wire rope. Under the pull of the winding steel wire rope, the connecting rod 13 is lifted upward, thereby driving the mounting base 11 to move up and down. When the mounting base 11 rises, the collection box 12 can be raised to the upper opening of the sedimentation tank 9, making it convenient for the staff to take out the collection box 12 and clean the sediment and silt inside. After cleaning, the steel wire rope is released, and under the pressure of the mounting base 11, the collection box 12 falls to the bottom of the sedimentation tank 9 to continue the centralized collection of sediment and silt.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
