[0002] Sand making, or the production of artificial sand, is the process of converting various natural rocks or industrial by-products (such as tailings, construction waste, etc.) into fine-grained materials that meet the standards for construction sand through crushing, screening and other processes. With the increasing depletion of natural river sand resources and the strengthening of environmental protection regulations, sand making technology has developed rapidly and has become an important way to meet the demand for high-quality sand and gravel in the modern construction industry. Large rocks are crushed into smaller particles using jaw crushers, cone crushers, impact crushers and other equipment. The crushing process requires the selection of appropriate crushing equipment and crushing ratio based on the characteristics of the raw materials and the requirements of the finished sand.

First, the stirring blade is driven to rotate by the second motor to stir and aerate the collected sludge. The odor generated inside is absorbed by the gas filter device to reduce the bacterial content in the air. Subsequently, the aerated sewage is transferred to the middle of the first baffle and the second baffle by the second delivery pump.

Under the action of the first filter layer, the second filter layer, the third filter layer and the fourth filter layer, the clean water and the floccules are stratified to improve the overall filtering effect. Subsequently, the filtered clean water is re-delivered to the interior of the filter box on the other side of the second baffle by the third delivery pump, sterilized and disinfected by an ultraviolet sterilization lamp, and finally detected by a water quality detection sensor before discharge.

[0016] In the present invention, by setting a drying structure, the floccules precipitated inside the filter structure are conveyed and collected into the interior of the drying box by the fourth delivery pump, and are uniformly placed on the upper end of the filter screen for gravity filtration. Subsequently, the interior of the drying box at the lower end of the filter layer paper is vacuumed by the cooperation of a vacuum pump and an exhaust pipe. Under the condition of vacuum adsorption by gravity, the clear water in the floccules is filtered out. After the filtration is completed, the interior is steam dried by a steam dryer, thereby further reducing the water content in the sludge and greatly improving the overall treatment effect. The treated sludge can be dumped by pulling out the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

The internal auger shaft 107 is driven to rotate by the driving motor 102 under the action of the transmission device 103. The sewage is put into the inside of the filter plate 106 from the retaining ring 101 and the feed port 105. The sewage is transferred by the rotation of the auger shaft 107. The sewage falls into the inside of the treatment shell 104 at the lower end of the filter plate 106, and the particulate matter is discharged from the other direction, achieving preliminary screening and filtration, providing convenience and basis for subsequent treatment; By setting the screening structure 3, when in use, the sewage filtered by the primary screening structure 1 is collected by the first sludge pump 301, and the filtered particles are collected by the second sludge pump 304, and are placed in the processing box 303 respectively. When the particles enter the processing box 303, the crankshaft 312 is driven to rotate by the first motor 313, and the metal filter 311 is shaken up and down under the action of the torsion spring 314, so as to realize the cleaning and filtering of the particles again. At the same time, the particles in the shaking process are washed with the water spray plate 310 and the water pump 316 to wash away the sludge on the surface, which is convenient for subsequent direct recycling and reducing the sludge content inside. The treated particles are uniformly transported out under the action of the auger conveyor 305, and the sludge slurry produced by the filtration is transported back to the other side of the processing box 303 by the first delivery pump 306, and mixed with the sludge slurry collected initially, so as to facilitate the subsequent steps. By setting the filtering structure 6, the sludge slurry in the screening structure 3 is transferred to the inside of the filtering box 605 through the peristaltic pump 5 during use. First, the stirring blade 608 is driven by the second motor 609 to rotate, and the collected sludge is stirred and aerated. The odor generated inside is absorbed by the gas filter device 602 to reduce the bacterial content in the air. Then, the aerated sewage is transported to the middle of the first baffle 610 and the second baffle 612 through the second delivery pump 601. The sewage is treated with drugs through the cooperation of the intelligent delivery device 603 and the drug delivery pipe 611. Under the action of the first filter layer 615, the second filter layer 616, the third filter layer 617 and the fourth filter layer 618, the clean water and the flocculent are separated to improve the overall filtering effect. Then, the filtered clean water is re-delivered to the inside of the filtering box 605 on the other side of the second baffle 612 through the third delivery pump 604, and sterilized and disinfected by the ultraviolet sterilization lamp 614. Finally, it is detected by the water quality detection sensor 613, and then it can be discharged. By setting up the drying structure 7, the floccules precipitated inside the filtering structure 6 are conveyed and collected into the drying box 707 by the fourth conveying pump 704, and are uniformly placed on the upper end of the filter screen 709 for gravity filtration. Subsequently, the interior of the drying box 707 at the lower end of the filter layer paper 710 is vacuumed by the vacuum pump 703 and the exhaust pipe 702. Under the condition of vacuum adsorption by gravity, the clean water in the floccules is filtered out. After the filtration is completed, the interior is steam dried by the steam dryer 708, so as to further reduce the water content in the sludge and greatly improve the overall treatment effect. The treated sludge can be dumped by extracting the filter screen 709.
