Description

Technical Field

[0001] This utility model relates to the field of fine sand classification technology, specifically to a fine sand classification processing mechanism for a sand washing system. Background Technology

[0002] A sand washing system is an equipment system used to clean sand and gravel, mainly to remove impurities and dirt from the surface of sand and gravel, improving their quality. A sand washing system typically consists of a sand washing machine, conveying equipment, and a control system, and is widely used in construction, road, and railway projects. The sand washing machine uses a motor to drive an impeller to rotate. The impeller causes the sand and gravel to tumble and grind in the washing tank, breaking down the water vapor layer on the surface of the sand particles. Simultaneously, water is added to create a strong water flow, washing away impurities and lighter foreign objects, which are then discharged through an overflow outlet, completing the cleaning process. Sand washing systems are widely used in construction sites, sand and gravel plants, glass factories, and many other fields. It can process various materials such as river pebbles, stone powder, limestone, granite, river sand, and manufactured sand, meeting high-standard construction sand requirements. In sand washing systems, fine sand usually needs to be graded. Most existing grading devices use horizontal filter screens for grading, and the screens are shaken to filter out the fine sand for grading. The sand and gravel filtered out by the screens are then processed. This grading efficiency is low, affecting the overall efficiency of the sand washing process.

[0003] Therefore, this utility model provides a fine sand grading and processing mechanism for a sand washing system. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a fine sand grading mechanism for a sand washing system, including a grading box 1, a rotating cylinder 5 rotatably fitted inside the grading box 1, a driving structure installed on one side of the grading box 1, the driving structure corresponding to the rotating cylinder 5, a hopper 13 fixed on the periphery of the rotating cylinder 5, a material guiding structure installed inside the rotating cylinder 5, a plurality of first filter holes 9 opened on the periphery of the rotating cylinder 5, the material guiding structure corresponding to the first filter holes 9, and a filter plate 10 snapped and fixed inside the hopper 13, the filter plate 10 corresponding to the first filter holes 9.

[0022] In this embodiment, a support frame 3 is fixed on the grading box 1. The support frame 3 is rotatably connected to the rotating drum 5. The driving structure includes a motor 2 fixed on one side of the support frame 3. The output end of the motor 2 is fixedly connected to the rotating drum 5. A rotating frame 4 is fixed on the support frame 3. The rotating frame 4 is a ring structure. The rotating frame 4 is rotatably connected to the rotating drum 5 and supports the rotating drum 5 through the rotating frame 4.

[0023] Specifically, starting motor 2 will drive the rotating drum 5 to rotate, thereby driving the rotating drum 5 to perform filtration.

[0024] The support frame 3 has an opening 6 on one side, which is connected to the rotating drum 5. The opening 6 corresponds to the material guiding structure. The grading box 1 has an outlet 8 on one side.

[0025] Specifically, when the rotating drum 5 rotates, the filter plate 10 and the first filter hole 9 can filter the fine sand. The fine sand that can pass through the filter plate 10 and the first filter hole 9 falls onto the material guiding structure inside the rotating drum 5. Some fine sand that cannot be filtered falls into the grading box 1 as the rotating drum 5 rotates until it reaches the bottom, thus achieving the grading and filtration of fine sand.

[0026] The material guiding structure includes a first guide plate 7 and a second guide plate 14. A guide groove 15 is provided in the first guide plate 7. The guide groove 15 has an inclined structure. The first guide plate 7 is located on the inner side of the rotating drum 5. Brush bristles are fixed on the lower side of the first guide plate 7. The brush bristles correspond to the first filter holes 9. A plurality of second filter holes 11 are provided in the filter plate 10. A plurality of locking blocks 12 are fixed on the filter plate 10. A locking groove is provided in the hopper 13. The locking groove corresponds to the locking block 12. The filter plate 10 is in contact with the rotating drum 5.

[0027] Specifically, the second guide plate 14 is fixedly connected to the support frame 3 for feeding. After the fine sand is guided by the second guide plate 14, it enters the hopper 13 and then falls into the guide trough 15 after being filtered by the second filter hole 11 and the first filter hole 9. It can then flow out through the guide trough 15.

[0028] When it is necessary to change the size of the fine sand to be filtered, simply pull the filter plate 10 so that the slot and the block 12 can be engaged, and the filter plate 10 can be removed and replaced to adjust the size of the filter.
