Description

Technical Field

[0001] This utility model relates to the field of fine sand recovery technology of manufactured sand, and in particular to a fine sand recovery device for manufactured sand. Background Technology

[0002] The manufactured sand fine sand recovery device is a specialized piece of equipment used to recover fine sand lost during the manufactured sand production process. It aims to improve the utilization rate of sand resources, reduce resource waste and environmental pollution, and prevent the waste of fine sand. It recycles and reuses fine sand that might otherwise be discarded, thereby increasing the utilization rate of raw materials in manufactured sand production, reducing production costs, minimizing environmental pollution from fine sand discharged with wastewater, and reducing the difficulty and cost of wastewater treatment. This makes the manufactured sand production process more environmentally friendly. The recovered fine sand can be returned to the production process to adjust the gradation of the manufactured sand, making its particle composition more reasonable, improving its quality, and meeting the performance requirements of different projects.

[0003] In the production of cast iron pots, it is necessary to clean the fine sand adhering to the surface of the cast iron pots. Generally, shot blasting machines are used for cleaning. However, the fine sand discharged from existing shot blasting machines is usually directly piled on the ground during cleaning. Moreover, the fine sand contains a lot of dust, which will be scattered everywhere, causing environmental pollution. The fine sand needs to be swept manually, which is inconvenient and brings a certain amount of workload. In addition, the fine sand is easy to stick directly to the inner wall of the container when discharged. Long-term adhesion can easily cause blockage at the bottom of the container, making it difficult to discharge the fine sand and affecting the normal operation of the equipment.

[0004] An existing patent (publication number: CN213162313U) discloses a fine sand collection device, comprising a holding chamber with a feeding port at the top and a fine sand bin at the bottom. Scraping mechanisms are installed on the outer walls of both sides of the holding chamber. Each scraping mechanism includes a cylinder, with a sliding plate connected to the bottom of the cylinder via a piston rod. A connecting rod is tightly welded to one side of the sliding plate. A vertically shaped hole is formed on the outer wall of the holding chamber near the connecting rod. This fine sand collection device's scraping mechanism can promptly scrape off the fine sand adhering to the inner wall of the holding chamber and collect it through the fine sand bin at the bottom, facilitating regular cleaning and preventing difficult external cleaning. Furthermore, the dust removal bin absorbs and cleans the internal dust, preventing pollution from external discharge. The dust removal wheel ensures that the fine sand at the bottom of the holding chamber is not easily clogged, facilitating the downward movement of the fine sand and ensuring normal equipment operation.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, current methods for recovering fine sand from manufactured sand involve directly using multi-layer sieves to screen and recover the fine sand. While this method can screen and recover fine sand, the screening efficiency is not only low, but the screening effect is also not ideal, resulting in insufficient practicality.

[0006] Therefore, a device for recovering fine sand from manufactured sand is proposed. Utility Model Content

After stirring, the power is turned on and the conveying pump 26 is started to send the material into the hydrocyclone 11 through the installation pipe 25 and the fixed pipe 27. Then the hydrocyclone 11 uses centrifugal force to separate coarse and fine particles. The fine particles overflow from the top with the water and return to the water tank 31 through the return pipe 32. The coarse particles fall into the screen frame 13. The servo motor 15 drives the cam 17 to rotate, causing the screen frame 13 to vibrate and further screen the fine sand. Then the water pump 37 of the washing mechanism 3 sends the water in the water tank 31 to the hydrocyclone 11 through the conveying pipe 33 to wash the recycled fine sand.
