Description

Technical Field

[0001] The invention relates to the technical field of construction mud treatment, and in particular to a mud sedimentation and separation device. Background Art

[0002] With the acceleration of urbanization, mud generated by the construction industry has become one of the important environmental issues. Traditional treatment methods usually include natural sedimentation, chemical flocculation, mechanical filtration, etc. Although these methods have reduced pollution to a certain extent, they generally have problems such as low efficiency, high cost, and easy to cause secondary pollution. In recent years, with the enhancement of environmental awareness and technological progress, more and more research has focused on how to treat construction mud efficiently and at low cost.

[0003] The more common construction mud treatment methods currently include: -Natural sedimentation method: by extending the slurry residence time, solid particles are allowed to naturally settle to the bottom of the container, thereby achieving the purpose of solid-liquid separation. The advantage is that no additional chemicals need to be added, but the disadvantage is that the processing speed is slow and the area occupied is large.

[0004] -Chemical flocculation: Adding an appropriate amount of flocculant promotes the aggregation of fine particles to form larger agglomerates, thereby accelerating the sedimentation rate. This method can significantly shorten the processing time, but requires precise control of the dosage and may introduce new chemical pollution.

[0005] - Mechanical filtration: Use a filter or other filter media to remove suspended matter from the water. This method has a fast processing speed and is suitable for large-scale continuous operations, but the equipment investment is high and the maintenance is complicated.

[0006] Deficiencies of the prior art: The above methods each have their own advantages, but each also faces certain limitations. For example, the natural sedimentation method is time-consuming and inefficient; the chemical flocculation method may bring the risk of secondary pollution; and the mechanical filtration method has a large initial investment and high operating and maintenance costs. Therefore, this application provides a mud sedimentation and separation device to meet the needs. Summary of the invention

Two groups of mounting holes 1102 are provided and penetrate the drive shaft 107. The mounting rod 1103 penetrates the inner wall of one side of the mounting groove 1101 and is adapted to the size of the mounting hole 1102. The mounting assembly 110 also includes a second slide groove 1104 and a second slider 1105, a second spring 1106 and a pull plate 1107, the second slide groove 1104 is opened inside the stirring shaft 108 and is located on the outer periphery of the mounting rod 1103, the second slider 1105 is fixedly connected to the mounting rod 1103 and slidably connected to the second slide groove 1104, the second spring 1106 is sleeved on the outer periphery of the mounting rod 1103 and the two ends are respectively fixedly connected to one side of the second slider 1105 and the inner wall of one side of the second slide groove 1104, the pull plate 1107 is fixedly connected to the outer end of the mounting rod 1103, and the installation component 110 is provided, and the pull plate 1107 is pulled outward to drive the mounting rod 1103 to move outward and the second spring 1106 is actuated by the second slider 1105. After the mounting rod 1103 is removed from the mounting hole 1102, the stirring shaft 108 and the stirring rod 109 can be removed for cleaning by moving downward. After cleaning, the stirring shaft 108 is inserted into the mounting groove 1101 so that the mounting hole 1102 and the mounting rod 1103 are on the same axis. Then, the pull plate 1107 is released, and the second spring 1106 rebounds and drives the mounting rod 1103 to move inward through the second slider 1105. When the mounting rod 1103 is inserted into the mounting hole 1102, the installation of the stirring shaft 108 is completed.

[0031] Working principle: The muddy water is discharged from the feed pipe 103 into the mixing tank 101, and then the flocculating agent is added to the mixing tank 101 through the dosing device 104 to make the muddy water flocculate. At this time, the motor 105 drives the driving shaft 107 to rotate, and the driving shaft 107 drives the stirring rod 109 to rotate through the stirring shaft 108, so as to stir and mix the muddy water, so that it can fully react with the flocculating agent, so that the large particles with a larger specific gravity are initially precipitated, and enter the collecting bin 602 through the water outlet. The muddy water in the collecting bin 602 is extracted by the first liquid pump 4. At this time, the second filter screen 603 blocks the flocculated impurities, and then the first liquid pump 4 is used to send the muddy water after the initial filtration into the first processing box 201, and the muddy water enters the partition 2 from the top of the fixed plate 218. 07 surface, the staggered partitions 207 are used to further slow down the water flow speed and promote the deposition of fine particles. The muddy water enters the first water outlet 206 from the second water outlet 210, and enters the sewage pipe 212 from the sewage outlet 211, and is finally discharged into the collection bin 602. The fine particles remaining on the surface of the horizontal plate 209 are driven by the electric push rod 216 to move the push plate 217, so that the push plate 217 removes the fine particles precipitated on the surface of the horizontal plate 209, reducing the sludge residue inside the box. The muddy water that has undergone secondary precipitation in the first treatment box 201 is pumped into the second treatment box 301 through the second liquid pump 5, and the small particles that have not been completely precipitated are intercepted through the microporous ceramic filter element 306. At this time, the purified muddy water is discharged from the clean water outlet 307; When the stirring rod 109 needs to be replaced, the pull plate 1107 is pulled outward to drive the mounting rod 1103 to move outward and the second spring 1106 is squeezed through the second slider 1105. When the mounting rod 1103 is moved out of the mounting hole 1102, the stirring shaft 108 and the stirring rod 109 are moved downward to remove them for cleaning. After cleaning, the stirring shaft 108 is inserted into the mounting groove 1101 and the mounting hole 1102 and the mounting rod 1103 are on the same axis. Then the pull plate 1107 is released, the second spring 1106 rebounds and drives the mounting rod 1103 to move inward through the second slider 1105. When the mounting rod 1103 is inserted into the mounting hole 1102, the installation of the stirring shaft 108 is completed. This design can make the installation and disassembly of the stirring shaft 108 and the stirring rod 109 simpler and faster, and effectively improve the cleaning efficiency of the stirring rod 109.

[0032] The technical solution provided by the present invention is that when the construction mud enters the primary sedimentation component from the feed inlet, it is quickly mixed with the help of an agitator, so that larger solid particles are quickly settled; then the liquid flows into the intermediate sedimentation component, and after being guided by multiple layers of partitions, the water flow becomes smooth and slow, which is conducive to the stable sinking of fine particles; then it enters the advanced filtration component, and the precise interception function of the microporous ceramic filter element is used to completely remove residual impurities; finally, clean water is discharged through the clean water outlet.
