[0016] The present invention also provides a plurality of mixed waste sand recovery methods, comprising the following steps:

[0017] S1. The sand-water mixture enters the hydrocyclone through the feed pipe and the third pipe, and the hydrocyclone is started, so that the hydrocyclone discharges the fine sand through the outlet at the bottom through the principle of centrifugal separation, and the fine sand falls into the vibrating screen. At this time, the vibration motor is started, so that the vibration motor can drive the vibrating screen to vibrate, so that the device vibrates and dehydrates the fine sand and moves the position of the processed fine sand to the output end of the vibrating screen for recovery;

[0018] S2. Starting the hydraulic rod can drive the guide plate to rotate about the central axis of the lifting block, thereby adjusting the angle of fine sand discharge, and starting the servo motor so that the servo motor drives the fourth bevel gear to rotate, and then drives the third bevel gear and the first connecting rod to rotate through the shape of the fourth bevel gear, so that the first connecting rod drives the second bevel gears at both ends to rotate when rotating, and drives the first bevel gear and the screw to rotate, so that when the screw rotates, it drives the lifting block to rise and fall through its own shape, so that the device can adjust the discharge of fine sand at multiple angles;

[0019] S3. After vibration filtration, the wastewater will fall into the bottom of the recovery body. After separating the sand-water mixture, the hydrocyclone will discharge the wastewater through the return pipe. Since the bottom of the return pipe is connected to the interior of the energy recovery box, the energy recovery paddle is driven by water pressure to rotate and then discharged through the drain port. When the energy recovery paddle rotates, it drives the second connecting rod to rotate, and drives the fifth bevel gear to rotate, and then drives the sixth bevel gear, the third connecting rod and the seventh bevel gear to rotate through the shape of the fifth bevel gear, and drives the eighth bevel gear to rotate through the shape of the seventh bevel gear when rotating. The eighth bevel gear drives the fourth connecting rod to rotate, and the fourth connecting rod drives the ninth bevel gear to rotate.

[0020] S4. After the wastewater inside the recovery body is stirred by the stirring disc, the first solenoid valve is opened to allow the sand-water mixture to be transported through the delivery pump. At this time, the connection between the second solenoid valve and the feed pipe is closed to allow the second pipe and the third pipe to be connected and then flow back into the interior of the hydrocyclone for further processing, so as to achieve the effect of recycling the kinetic energy generated when the wastewater is discharged.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention arranges the cooperation of extension plates, extension frames, screw rods and other structures, so that the device can start the hydraulic rod to drive the guide plate to rotate about the central axis of the lifting block, thereby adjusting the angle of fine sand discharge, and starts the servo motor, so that the servo motor drives the fourth bevel gear to rotate, and then drives the third bevel gear and the first connecting rod to rotate through the shape of the fourth bevel gear, so that the first connecting rod drives the second bevel gears at both ends to rotate when rotating, and drives the first bevel gear and the screw to rotate, so that when the screw rotates, the lifting block is driven to rise and fall through its own shape, thereby achieving the purpose of facilitating the device to adjust the discharge of fine sand at multiple angles.

[0023] The present invention cooperates with the first pipeline, the first solenoid valve, the delivery pump and other structures to enable the device to allow the sand-water mixture to enter the inside of the hydrocyclone through the feed pipeline and the third pipeline, and start the hydrocyclone, so that the hydrocyclone discharges fine sand through the outlet at the bottom through the principle of centrifugal separation, and the fine sand falls into the inside of the vibrating screen, and then the vibration motor is started, so that the vibration motor can drive the vibrating screen to vibrate, so that the device vibrates and dehydrates the fine sand and moves the position of the processed fine sand to the output end of the vibrating screen for recovery, and after the agitator stirs the wastewater inside the recovery body, the first solenoid valve is opened, so that the sand-water mixture is transported through the delivery pump, and at this time, the connection between the second solenoid valve and the feed pipeline is closed, so that the second pipeline and the third pipeline are connected and then flow back into the inside of the hydrocyclone for further processing, so as to achieve the purpose of recycling the kinetic energy generated when the wastewater is discharged.

[0024] The present invention cooperates with structures such as an energy recovery box, an energy recovery paddle, and a second connecting rod so that after vibration filtration, the wastewater can fall into the bottom of the recovery body. After the hydrocyclone separates the sand-water mixture, the wastewater is discharged through a reflux pipe. Since the bottom end of the reflux pipe is connected to the interior of the energy recovery box, and the energy recovery paddle is driven to rotate by water pressure and then discharged through a drain port, the energy recovery paddle drives the second connecting rod to rotate when rotating, and drives the fifth bevel gear to rotate, and then drives the sixth bevel gear, the third connecting rod and the seventh bevel gear to rotate through the shape of the fifth bevel gear, and drives the eighth bevel gear to rotate when rotating through the shape of the seventh bevel gear, the eighth bevel gear drives the fourth connecting rod to rotate, the fourth connecting rod drives the ninth bevel gear to rotate, the ninth bevel gear drives the tenth bevel gear to rotate through its own shape, and then drives the fifth connecting rod and the stirring disk to rotate through the tenth bevel gear, so that the wastewater inside the recovery body is stirred when the stirring disk rotates to prevent it from sinking to the bottom, so as to achieve the purpose of reusing the discharged water energy.

At this time, the vibration motor (5) is started, so that the vibration motor (5) can drive the vibrating screen (4) to vibrate, so that the device vibrates and dehydrates the fine sand and moves the position of the processed fine sand to the output end of the vibrating screen (4) for recovery; S2, starting the hydraulic rod (606) to drive the guide plate (605) to rotate about the central axis of the lifting block (604), thereby adjusting the discharge angle of the fine sand, and starting the servo motor (612), so that the servo motor (612) drives the fourth bevel gear (611) to rotate, and then drives the third bevel gear (610) and the first connecting rod (609) to rotate through the shape of the fourth bevel gear (611), so that the first connecting rod (609) drives the second bevel gears (608) at both ends to rotate when rotating, and drives the first bevel gear (607) and the screw rod (603) to rotate, so that when the screw rod (603) rotates, it drives the lifting block (604) to rise and fall through its own shape, so that the device can adjust the discharge of fine sand at multiple angles; S3. After vibration filtration, the wastewater will fall into the bottom of the recovery body (1). After the hydrocyclone (707) separates the sand-water mixture, the wastewater will be discharged through the return pipe (710). Since the bottom of the return pipe (710) is connected to the inside of the energy recovery box (801), the energy recovery paddle (802) is driven by water pressure to rotate and then discharged through the drain port (12). When the energy recovery paddle (802) rotates, it drives the second connecting rod (803) to rotate, and drives the fifth bevel gear (804) to rotate, and then drives the sixth bevel gear (805), the third connecting rod (806) and the seventh bevel gear (805) through the shape of the fifth bevel gear (804).
