When the existing filter screen 4 is used for solid-liquid separation of the precursor, the solid phase is easy to block the filter screen 4, so that the filtering rate is low, when the embodiment of the invention is practical, firstly, the precursor to be processed is put into the separating tank 2 through the feed port 3, the material falls on the surface of the filter screen 4 under the action of gravity in the separating tank 2, the liquid phase passes through the blades 7, the solid phase is blocked by the filter screen 4 and stays on the surface of the filter screen 4, at the moment, the hydraulic cylinder 5 is started, the hydraulic cylinder 5 is operated, the transmission mechanism 8 is driven to move downwards, the air in the separating tank 2 is compressed in the moving process of the transmission mechanism 8, the pressure is applied to the precursor in the separating tank 2, the liquid phase in the precursor is forced to accelerate through the filter screen 4, and the transmission mechanism 8 is synchronously driven to rotate the mounting shaft 6 anticlockwise with the view angle of figure 5 when in operation, the blade 7 is driven to rotate anticlockwise in the process of rotating the mounting shaft 6, the blade 7 can strike the solid phase on the surface of the filter screen 4 when rotating, so that the solid phase is continuously moved, the situation that

connecting pipe 11, the existing device has insufficient stability and adaptability in some occasions requiring accurate control of air pressure, when the embodiment of the invention is used, the air pump 12 operates to increase the air pressure in the discharge cavity 10 through the first air receiving pipe 13, the air pressure in the discharge cavity 10 near the air pump 12 is continuously increased, the air pressure is applied to the baffle 28 and the air plate 27, the baffle 28 and the air plate 27 are forced to move towards the position of the discharge hole 19, it is noted that due to the arrangement of the bonding mechanism 17, a certain degree of viscosity exists between the baffle 28 and the air plate 27, when the baffle 28 and the air plate 27 move towards the position of the discharge hole 19, detachment of the baffle 28 and the air plate 27 is avoided, the liquid phase flows to the direction of the first air receiving pipe 13 through the gap between the baffle 28 and the air plate 27, and when the air plate 27 moves towards the position of the discharge hole 19, the first spring 15 is synchronously extruded, so that deformation occurs, elastic potential energy is generated, finally, the baffle 28 continuously moves under the action of the air pressure and is in contact with the inner wall of the discharge cavity 10, and the baffle 28 generates suction force with the inner wall of the discharge cavity 10 under the action of the magnetic suction mechanism 18, at this time, the baffle 28 cannot move continuously and seals the lower part of the connecting pipe 11, the liquid phase cannot flow into the discharging cavity 10 through the connecting pipe 11, the discharging cavity 10 is in a sealed state, however, the air pressure at the side of the air plate 27 close to the bonding mechanism 17 is still in an increased state, the baffle 28 cannot move at this time, the air pressure can drive the air plate 27 to move, and it is noted that the baffle 28 is still influenced by the air pressure and the magnetic attraction mechanism 18 when the baffle 28 collides with the discharging cavity 10, so that the baffle 28 is in a stressed static state when the baffle 28 collides with the discharging cavity 10, the inside of the discharging cavity 10 is ensured, the tightness at the side of the air plate 27 far from the baffle 28 is ensured, the air plate 27 continuously moves to the position of the discharging hole 19 against the viscosity of the bonding mechanism 17 at this time, the air pressure at the side of the air plate 27 far from the bonding mechanism 17 is increased when the air plate 27 moves, the liquid phase in the discharge cavity 10 is enabled to move due to the change of the air pressure, when the air plate 27 is closer to the discharge hole 19, the air pressure in the discharge cavity 10 is larger, the flow rate and the flow rate of the liquid phase are increased, when the air plate 27 is further away from the discharge hole 19, the air pressure in the discharge cavity 10 is reduced, the flow rate and the flow rate of the liquid phase are reduced, thereby realizing the function of precisely controlling the liquid phase, stability and adaptability of the device are improved, when the liquid phase is not required to be discharged, the air pump 12 pumps air in the discharge cavity 10 through the first air receiving pipe 13, at the moment, the air plate 27 is in contact with the air plate 27, the pressure on one side of the baffle plate 28, which is far away from the air plate 27, is reduced, the baffle plate 28 and the air plate 27 are not pushed to move, the pressure exerted by the air plate 27 is further ended, the first spring 15 releases elastic potential energy instantaneously, and pushes the air plate 27 to reset, the elastic potential energy released by the first spring 15 can overcome the suction force of the magnetic suction mechanism 18, the weight of the air plate 27 and the friction force generated during the movement of the baffle plate 28 are finally, the air plate 27 contacts with the air plate 27 and the reset force generated during the collision, and the reset force is
