Sand and water separation system and method

Abstract

The invention relates to a sand and water separation system and method, can effectively separate mud, water and sand in a mud, sand and water mixture, and also can dehydrate the sand and the water efficiently. The sand and water separation system comprises a dehydration screen, a rotational flow device or a rotational flow device group and a vibrating and screening device; the vibrating and screening device and a wide-amplitude water-storage-type dehydration screen are integrated on a base; the rotational flow device or the rotational flow device group is integrated above the wide-amplitude water-storage-type dehydration screen through a support frame; a sand and water mixture is conveyed between the vibrating and screening device and the wide-amplitude water-storage-type dehydration screen through a sand flowing groove; the wide-amplitude water-storage-type dehydration screen is positioned on a rack through a shock absorber; the wide-amplitude water-storage-type dehydration screen is driven by a shock excitation motor or a cam wheel driving mechanism; a wide-amplitude water storage groove is positioned below the wide-amplitude water-storage-type dehydration screen; a material inlet of the rotational flow device or the rotational flow device group is communicated with an outlet of a slurry pump at the side part of the rack through a conveying pipeline; and the motor drives the slurry pump through a belt driving mechanism.

Description

technical field [0001] The invention relates to a sand-water separation system and a sand-water separation method capable of effectively separating mud, water and sand in a silt-water mixture and efficiently dehydrating the sand and water, belonging to the field of sand-water separation system manufacturing. Background technique [0002] 1. CN201524486U, name "sand water separation and recovery system", which includes mud and sand water classification equipment, sand dewatering equipment and mud dehydration equipment; the mud and sand water classification equipment includes a working cylinder, a feeding pipe, an overflow pipe, and a sand outlet , the feed pipe and the overflow pipe are fixedly connected around the working cylinder, the grit chamber is arranged at the lower end of the working cylinder, and the working cylinder is a hollow cylinder connected with a An inverted cone communicating with the cylinder; the sand dewatering equipment includes a screen box, a vibrator...

AI Technical Summary

Problems solved by technology

Its shortcomings: first, large investment, large floor area, and high power consumption; second, low efficiency of sand-water separation; third, fixed sand-water separation system, which cannot be moved; fourth, it remains on the screen surface of the dewatering screen The coarse sand cannot naturally form a sand wall on the dewatering screen plane, so it cannot achieve continuous dehydration during operation

[0003] 2. In the context of cobblestones and other water-based extraction of machine-made sand and raw sand, the current market basically adopts: drum type sand washing machine, winch cage type sand twisting machine and wheel type sand lifting machine and some areas. The bucket-lift sand lifter is used to extract coarse sand. When the above methods are used alone, there are serious tailings.

Not only does the water content of the finished products prepared by the above-mentioned equipment remain high, but the gradation of the produced machine-made sand and raw sand products is unreasonable, and the medium and fine sand run out seriously, and the finished products with qualified grading cannot be obtained, which has caused Serious waste, but also secondary pollution caused by the environment, etc. For this reason, in order to achieve the gradation of qualified machine-made sand and original sand, and to prevent secondary pollution, the manufacturer has to be equipped with a dehydrator and a tailing There are many auxiliary equipment such as sand recovery devices, which have caused many problems such as excessive investment in equipment in the system, high unit price, large floor area, and excessive power consumption.
