[0013] A method for using a solid-liquid separation device comprises the following steps:

[0014] Step 1: Slowly invert the solution containing nano-calcium carbonate into the inside of the feed hopper through the feed hopper, and enter the inside of the machine body through the feed hopper. At this time, the solution passes through the anti-blocking mechanism to achieve solid-liquid separation. In this process, the second synchronous wheel is rotated by starting the motor, and the first synchronous wheel is rotated under the action of the belt, which causes the transmission rod to rotate, thereby causing the eccentric wheel to rotate. When the convex surface of the eccentric wheel contacts the bottom end of the movable plate, the movable column moves upward, and the spring is in a compressed state. Under the action of the movable column, the slider moves along the inner wall of the slide groove, causing the filter to tilt upward. When the concave part of the eccentric wheel rotates, the movable column moves downward under the elastic force of the spring, thereby driving the filter to move downward, completing the shaking of the filter.

[0015] Step 2: After the solid-liquid separation is completed, the turntable is rotated by the drive of the motor, thereby driving the fixed column to rotate, thereby driving the annular plate to reciprocate up and down along the outside of the turntable, thereby driving the cylinder to move synchronously, and further driving the piston to move synchronously. When the piston moves upward, the air outlet one-way valve is closed, and the external atmospheric pressure enters the interior of the air cylinder through the air inlet one-way valve to replenish air. When the movable bar moves downward, the air inlet one-way valve is closed, and the gas inside the air cylinder enters the interior of the heating box through the connecting pipe. Since the interior of the heating box is provided with an electric heating wire, hot air will be generated. At this time, the hot air will enter the interior of the annular pipe through the air supply pipe and be sprayed through multiple nozzles to automatically dry the nano calcium carbonate.

[0016] Step 3: When the annular plate reciprocates up and down, it drives the rack plate to move synchronously, thereby driving the driving gear to rotate back and forth, thereby driving the rotating rod to rotate synchronously, and further driving the anti-blocking plate to rotate, thereby dredging the material inside the feed hopper.

[0017] The present invention provides a solid-liquid separation device and a method of use. It has the following beneficial effects:

[0018] 1.

[0019] 2.

[0041] A method for using a solid-liquid separation device comprises the following steps:

[0042] Step 1: The solution containing nano calcium carbonate is slowly inverted into the interior of the feed hopper 2 through the feed hopper 2, and enters the interior of the body 1 through the feed hopper 2. At this time, the solution passes through the filter screen 706 to achieve solid-liquid separation.

[0043] Step 2: After the solid-liquid separation is completed, the turntable 808 is rotated by the drive of the motor 11, thereby driving the fixed column 810 to rotate, thereby driving the annular plate 809 to reciprocate up and down along the outside of the turntable 808, thereby driving the cylinder 811 to move synchronously, and further driving the piston 805 to move synchronously. When the piston 805 moves upward, the air outlet one-way valve 804 is closed, and the external atmospheric pressure enters the interior of the air cylinder 802 through the air inlet one-way valve 806 to replenish air. When the movable bar 807 moves downward, the air inlet one-way valve 806 is closed, and the gas inside the air cylinder 802 enters the interior of the heating box 801 through the connecting pipe 803. Since the interior of the heating box 801 is provided with an electric heating wire, hot air will be generated. At this time, the hot air will enter the interior of the annular tube 812 through the air supply pipe 814 and be sprayed through a plurality of nozzles 813 to automatically dry the nano calcium carbonate.

[0044] Step 3: When the annular plate 809 reciprocates up and down, it drives the rack plate 901 to move synchronously, thereby driving the driving gear 902 to rotate back and forth, thereby driving the rotating rod 903 to rotate synchronously, and further driving the anti-blocking plate 904 to rotate, thereby clearing the material inside the feed hopper 2.

Under the action of the movable column (708), the slider (707) moves along the inner wall of the chute (705), causing the filter screen (706) to tilt upward. When the concave part of the eccentric wheel (702) rotates, at this time, under the elastic force of the spring (704), the movable column (708) moves downward, thereby driving the filter screen (706) to move downward to complete the shaking of the filter screen (706). Step 2: After the solid-liquid separation is completed, at the same time, the rotation of the turntable (808) is driven by the motor (11), which drives the fixed column (810) to rotate, drives the annular plate (809) to reciprocate up and down along the outside of the turntable (808), drives the cylinder (811) to move synchronously, and further drives the piston (805) to move synchronously. When the piston (805) moves upward, the outlet check valve (804) is closed, and the outside atmospheric pressure enters the inside of the air cylinder (802) through the inlet check valve (806) for air replenishment. When the movable bar (807) moves downward, the inlet check valve (806) is closed, and the gas inside the air cylinder (802) enters the inside of the heating box (801) through the connecting pipe (803). Since there is an electric heating wire inside the heating box (801), hot air will be generated. At this time, the hot air enters the inside of the annular pipe (812) through the air delivery pipe (814) and is sprayed out through a plurality of nozzles (813) to automatically dry the nano-calcium carbonate. Step 3: When the annular plate (809) reciprocates up and down, it drives the rack plate (901) to move synchronously, drives the driving gear (902) to rotate reciprocally, drives the rotating rod (903) to rotate synchronously, and further drives the anti-blocking plate (904) to rotate, so as to dredge the materials inside the feed hopper (2).
