Description

Technical Field

[0001] This utility model relates to the field of fine sand recovery technology, specifically a composite fine sand recovery device. Background Technology

[0002] The fine sand recovery machine is a piece of equipment developed for dewatering, demediuming, and desliming slurry materials. Its biggest advantage is its ability to effectively solve the problem of fine sand loss in the sand making industry. Also known as tailings recovery machine, fine sand extractor, fine sand collector, mud-sand separator, mud separator, sand-water mixture treatment system, etc., existing equipment suffers from low screening efficiency, easy discharge of fine sand with wastewater leading to resource waste, and the small size of the fine sand particles causing easy clogging of the screen, requiring frequent shutdowns for cleaning and impacting production efficiency.

[0003] In existing composite fine sand recovery devices, fine sand (especially materials with high mud content or uneven particle size) tends to adhere to or accumulate on the screen during screening, leading to screen blockage and reduced screening efficiency. Some devices rely solely on linear vibration or fixed-angle tilting of the screen frame, which is ineffective for treating sticky materials or fine sand with high moisture content, and easily causes material accumulation. Furthermore, in traditional devices, the screened fine sand mixed with water tends to settle at the bottom of the recovery tank, making it difficult to extract effectively, resulting in low recovery efficiency and potential wear on the slurry pump. This paper proposes a composite fine sand recovery device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5 This utility model provides a composite fine sand recovery device, including a recovery box 1, a first protective box at the rear of the recovery box 1, a first motor 2 inside the first protective box, a turntable 3 at the output end of the first motor 2, a connecting rod 4 rotatably connected to the front of the turntable 3 via a pin, a screen frame 5 rotatably connected to the other end of the connecting rod 4 via a pin, a screen mesh 6 inside the screen frame 5, a first support plate at the rear of the recovery box 1, a second protective box at the top of the first support plate, a second motor 7 inside the second protective box, a first rotating shaft 8 at the output end of the second motor 7, a striking rod 9 and a first bevel gear 10 on the outer surface of the first rotating shaft 8, a first support rod 11 on the inner wall of the recovery box 1, a third protective box 23 welded to the outer surface of the first support rod 11, a second rotating shaft 12 rotatably connected to the bottom wall of the third protective box 23 via a bearing, a second bevel gear 13 at the top of the second rotating shaft 12, and a hinge blade 14 on the outer surface of the second rotating shaft 12.

[0025] Specifically, the inner walls of the first and second protective boxes are provided with heat dissipation holes to facilitate heat dissipation of the first motor 2 and the second motor 7. The first rotating shaft 8 is rotatably connected to the interior of the front and rear walls of the third protective box 23 through bearings, and sealing rings are provided at the connection points with the front and rear walls of the third protective box 23 to prevent water from entering the third protective box 23 and affecting the normal operation of the first bevel gear 10 and the second bevel gear 13.

[0026] Please see Figures 1 to 3 A sliding plate 15 is provided on the left side of the recycling bin 1. The front and rear sides of the sliding plate 15 are in close contact with the front and rear inner walls of the recycling bin 1. A first push plate 16 is provided on the left side of the bottom of the screen frame 5.

[0027] Specifically, the slide plate 15 is tilted at a certain angle to the horizontal plane, the bottom of the first push plate 16 abuts against the top of the slide plate 15, and the first push plate 16 moves with the left and right movement of the screen frame 5, pushing the fine sand that falls above the slide plate 15 down.

[0028] Please see Figures 1 to 2 The front and rear inner walls of the recycling bin 1 are equipped with sliding frames 17. Both sides of the screen frame 5 are rotatably connected to rollers via pins. The front and rear ends of the screen frame 5 are engaged in the sliding frames 17. The left side of the sliding frames 17 is fixedly connected to a baffle by bolts.

[0029] Specifically, the rollers abut against the inner bottom wall of the sliding frame 17, which facilitates the rapid left and right sliding of the screen frame 5 to screen and dewater fine sand. The baffle can be removed by rotating the bolts so that the screen 6 and screen frame 5 can be replaced later.

[0030] Please see Figures 2 to 4 There are two striking rods 9, which are respectively connected to the front and rear sides of the third protective box 23. The first bevel gear 10 meshes with the second bevel gear 13. A water outlet pipe is provided on the rear side of the recycling box 1, and a second filter screen 18 is provided in the water outlet pipe.

[0031] Specifically, as the first rotating shaft 8 rotates, the striking rod 9 rotates as well, continuously striking the screen 6 to prevent fine sand from clogging the screen 6, while accelerating the dewatering speed of the fine sand. When the water level is higher than the outlet pipe, the excess water will be discharged from the recovery box 1. The second filter screen 18 filters the screen to prevent excessive loss of fine sand.

[0032] Please see Figures 1 to 3 A second support rod 19 is provided on the right side of the recycling bin 1, and a second push plate 20 is provided on the left end of the second support rod 19. The bottom of the push plate abuts against the top of the screen 6.

[0033] Specifically, as the screen frame 5 moves back and forth, the second push plate 20 continuously pushes the fine sand falling on the slide plate 15 to prevent the fine sand from accumulating.

[0034] Please see Figures 1 to 5An L-shaped conveying pipe is provided at the bottom of the recycling box 1. A slurry pump 21 is placed on the right side of the recycling box 1. A second L-shaped conveying pipe is provided at the output end of the slurry pump 21. A second support plate is provided on the right side of the recycling box 1. A hydrocyclone 22 is snapped into the inside of the second support plate. The other end of the second L-shaped conveying pipe is located at the feed end of the hydrocyclone 22. The other end of the first L-shaped conveying pipe is located at the feed end of the slurry pump 21.

[0035] Specifically, the fine sand at the bottom of the recovery box 1 is extracted by the slurry pump 21 and the hydrocyclone 22, and then the fine sand is dewatered and screened again.

[0036] During operation, the operator feeds fine sand onto screen 6, then starts the first motor 2, the second motor 7, the slurry pump 21, and the hydrocyclone 22. The output of the first motor 2 drives the turntable 3 to rotate, which in turn drives the connecting rod 4 connected to one side of the turntable 3 via a pin. The connecting rod 4 then drives the screen frame 5 and screen 6 to reciprocate left and right, screening and dewatering the fine sand. The screened and dewatered fine sand accumulates on screen 6 and slides out from the left side of screen frame 5 as screen frame 5 moves left and right, falling onto slide plate 15 and then sliding off onto a pre-placed conveyor belt or collection box under gravity. Simultaneously, the second push plate 20 at the bottom of screen frame 5 also moves left and right, continuously pushing the fine sand onto slide plate 15 to prevent accumulation. Furthermore, when screen frame 5 and screen 6 move to the far left, the right side of the first push plate 16 intersects with the screen frame 5... The right inner wall abuts against the screen. When the screen frame 5 and screen 6 move to the rightmost side, the push plate pushes the fine sand above the screen 6 to the left side of the screen 6 to prevent excessive accumulation of fine sand on the screen 6. After the fine sand is screened and dewatered, some fine sand will fall to the bottom of the recovery box 1 along with the water through the screen 6. At this time, the second motor 7 drives the first rotating shaft 8, the striking rod 9 and the first bevel gear 10 to rotate. The striking rod 9 can continuously strike the bottom of the screen 6 to prevent the screen 6 from clogging. The first bevel gear 10 meshes with the second bevel gear 13 and rotates. The second bevel gear 13 drives the second rotating shaft 12 and the auger blade 14 to rotate, stirring the fine sand and water to prevent the fine sand from settling and accumulating, which is not conducive to the extraction of the slurry pump 21. The slurry pump 21 extracts the fine sand from the bottom of the recovery box 1 and sprays the fine sand to the middle position of the screen 6 through the hydrocyclone 22 for screening and dewatering of the fine sand again.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
