However, when abnormal substances appear inside the sand and gravel, blockage is very easy to occur. In addition, most sand and gravel contain water, which causes the sand and gravel to be adsorbed together to form larger particles. When they are screened, they cannot pass through the screening equipment, thereby wasting most of the sand and gravel. In order to improve the screening efficiency, a regenerated sand and gravel double-layer water-washing screen and a method for using the screen have been developed. Summary of the invention

[0022] Embodiment 1: See also Figure 1-Figure 7 A double-layer water-washing screen for regenerated sand and gravel comprises an operating table 1, a drum 11 is arranged at the upper end of the operating table 1, a feeding cylinder 12 is arranged at the upper end of the operating table 1 and on one side of the drum 11, and one end of the feeding cylinder 12 extends to the inner cavity of the drum 11, and a guide cylinder 13 is connected to the lower end of the operating table 1; In this solution, one end of the drum 11 is rotatably connected to one side of the operating table 1. The outer surface of the drum 11 is a mesh component such as a gauze, and there is a certain angle between the drum 11 and the operating table 1, so that the sand and gravel move toward the side away from the feed cylinder 12. At the same time, the outlet cylinder 13 is used to conduct the sand and gravel after screening inside the drum 11, so that it can accurately conduct the sand and gravel to the filter component 3 for secondary screening.
[0023] Furthermore, the screening assembly 2 is mounted in the inner cavity of the drum 11 and is used for preliminary screening of the regenerated sand and gravel.
[0024] Among them, the screening assembly 2 includes a driving member 21 connected to the operating table 1, a driving rod 22 is provided at the output end of the driving member 21, and one end of the driving rod 22 extends to the inner cavity of the drum 11, and a connecting block 23 is provided at the end of the driving rod 22, and the outer surface of the connecting block 23 is fixedly connected to the inner wall of the drum 11.
[0025] A telescopic member 24 is rotatably installed at one end of the connecting block 23 away from the driving rod 22, and a push block 25 is provided at the output end of the telescopic member 24. Adjustment rods 26 are rotatably installed at both ends of the push block 25. At the same time, an adjustment block 28 is rotatably installed at one end of the adjustment rod 26 away from the push block 25, and the two adjustment rods 26 are rotatably connected by a limit plate 27. A plurality of groups of pressing rods 281 are provided on the outer surface of the adjustment block 28, and the regenerated sand and gravel are crushed and screened by the plurality of groups of pressing rods 281.
[0026] In this embodiment, the driving member 21 is a device with power output such as a motor, and is connected to an external control device, so that when the driving member 21 is started, it cooperates with the driving rod 22 to synchronously drive the connecting block 23 to rotate. Since the connecting block 23 is fixedly connected to the inner wall of the drum 11, the drum 11 rotates around the connection with the operating table 1, and the outer surface of the drum 11 away from the end of the driving member 21 is rotatably connected to the inner wall of the upper end of the operating table 1.
[0027] At the same time, the telescopic parts 24 are arranged on both sides of the inner cavity of the drum 11, one of the telescopic parts 24 is rotatably connected to the connecting block 23, and one end of the other telescopic part 24 penetrates and extends to the outside of the drum 11, and is fixedly connected to the operating table 1, and the telescopic part 24 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device.
[0028] When the telescopic member 24 is started, the push block 25 arranged at its output end is synchronously driven to move. Since the adjusting rods 26 are rotatably installed at both ends of the push block 25, when the push block 25 moves, the adjusting rod 26 is synchronously driven to move. At the same time, the adjusting block 28 is rotatably installed at the end of the adjusting rod 26, so that the adjusting block 28 moves synchronously with the adjusting rod 26, and the two adjusting blocks 28 are limited by the limit plate 27, so that the adjusting blocks 28 rotate around the connection with the limit plate 27, so as to adjust the distance between the two adjusting blocks 28 so that they fit the inner wall of the drum 11.
[0029] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.
[0030] Furthermore, a fixing rod 29 is provided at the end of the push block 25 , and one end of the fixing rod 29 passes through and extends to the outside of the limiting plate 27 .
[0031] Specifically, the outer surface of the fixing rod 29 is provided with anti-skid grooves, so that when the fixing rod 29 contacts with sand and gravel, the sand and gravel will not slide on the outer surface of the fixing rod 29, thereby improving the efficiency of sand and gravel filtering.
[0032] Furthermore, the filtering component 3 is assembled at the lower end of the operating platform 1, and is used to receive the regenerated sand and gravel after the initial screening by the screening component 2, and perform secondary screening on it.
[0033] The filter assembly 3 includes a bottom plate 31 connected to the operating table 1, a protective tube 311 is provided at the upper end of the bottom plate 31, and a power member 32 is provided on one side of the protective tube 311. A rotating block 33 is provided at the output end of the power member 32, and the end of the rotating block 33 penetrates and extends to the inner cavity of the protective tube 311.
[0034] A power rod 34 is rotatably mounted on one end of the rotating block 33 , and one end of the power rod 34 penetrates and extends to the outside of the protective tube 311 , while a movable block 35 is rotatably mounted on the end of the power rod 34 .
[0035] In this embodiment, the power member 32 is a device with power output such as a motor, and is connected to an external control device. When the power member 32 is started, it synchronously drives the rotating block 33 to rotate. At the same time, when the rotating block 33 rotates, it cooperates with the power rod 34 to drive the movable block 35 to rotate. Since the rotating block 33 is tilted as a whole, when the rotating block 33 rotates, the movable block 35 is driven to reciprocate.
[0036] A hole is provided on one side of the protective tube 311 close to the movable block 35 to provide a movable space for the movable block 35 so that the movable block 35 will not be disturbed when moving, thereby ensuring the normal operation of the screening.
[0037] Furthermore, a positioning plate 36 is rotatably mounted on the upper end of the bottom plate 31 and located on one side of the protective tube 311, and the outer surface of the positioning plate 36 is rotatably connected to one end of the movable block 35. A swing rod 37 is rotatably mounted on the outer surface of the upper end of the positioning plate 36, and a movable rod 38 is rotatably mounted on the end of the swing rod 37 away from the positioning plate 36.
[0038] Specifically, when the movable block 35 moves, the positioning plate 36 is driven to rotate around the connection with the bottom plate 31. Since the end of the positioning plate 36 is rotatably installed with a swing rod 37, when the positioning plate 36 moves, the swing rod 37 is synchronously driven to move, and cooperates with the movable rod 38 to provide power for the filter plate 391, so that it moves back and forth, and the sand and gravel are screened twice.
[0039] Furthermore, a collecting tube 39 is provided at the upper end of the bottom plate 31 and at one end away from the protective tube 311 , and the upper end of the collecting tube 39 is inclined.
[0040] A filter plate 391 is slidably mounted on the upper end of the collecting cylinder 39 , and the upper end of the filter plate 391 is rotatably connected to the end of the movable rod 38 .
[0041] Specifically, the sand and gravel after preliminary screening are transferred to the filter plate 391 through the outlet cylinder 13, and the filter plate 391 is continuously powered by the movable rod 38 to reciprocate the filter plate 391, thereby performing secondary screening on the sand and gravel on the filter plate 391 and improving the screening efficiency and sand and gravel quality.
[0042] Embodiment 2: See also Figure 8 A method for using a double-layer water-washing screen for regenerated sand and gravel comprises the following steps: S1, uniformly adding the regenerated sand and gravel to be processed into the feeding tube 12; S2, start the screening component 2 to perform preliminary screening on the regenerated sand and gravel entering the drum 11, and crush the part with larger particle size; S3, transferring the regenerated sand and gravel after the preliminary screening to the filter assembly 3 through the outlet cylinder 13 for secondary screening; S4. After the processing is completed, open the cover on one side of the drum to discharge the regenerated sand and gravel that cannot be screened inside.
