Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially a spiral sand separator. BACKGROUND

[0002] In the process of ore sand processing, sand separation is a key step. Waste such as sand and gravel in the process of ore sand mining reduces the purity of ore sand. Different sizes of sand and gravel can be screened from ore sand by a sand separator. The waste sand and gravel can be recycled for concrete processing, avoiding waste and reducing the cost of mining. With the acceleration of urbanization, the demand for concrete in building engineering is increasing. The core of sand and gravel screening technology is to separate ore sand of different particle sizes by physical methods to obtain raw materials that meet the requirements of concrete preparation. This not only helps to improve the overall performance of concrete, but also improves resource utilization and promotes the development of green building.

[0003] The existing sand separator usually uses a screen to separate sand and gravel of different sizes. The screen can rotate to separate sand and gravel more fully. For example, Chinese patent No. CN214347735U discloses a multifunctional high-efficiency spiral sand separator. After turning on the motor, the screen and the tank are rotated simultaneously through the transmission of the belt. The sand and gravel entering the screen will tumble inside the device. The smaller sand and gravel will fall into the housing through the screen during tumbling and be discharged through the discharge port. The larger sand and gravel will continue to tumble inside the inclined screen and be discharged through the discharge pipe. This saves time and effort, speeds up the work efficiency, and eliminates the need for manual screening.

[0004] However, in actual use, the screen holes of the screen are easily clogged by sand and gravel and debris. Maintenance and cleaning require a lot of time, which affects the working efficiency of the sand separator, reduces the user experience, and increases the construction period. UTILITY MODEL CONTENTS
