The feed rotary drive assembly is used to add plant solid residue into the circular tube 7, and utilize the right opening of the circular tube 7 and the inclined surface of the bottom inner wall to automatically guide the material into the right side of the feed hole 4. The feed rotary drive assembly is also used to drive the circular rotary seat 3 to rotate half a circle when the servo motor 12 is started, and utilize the rotation of the circular rotary seat 3 to drive the two feed holes 4 to rotate and exchange positions for alternating use;

[0027] A pressure-controlled extrusion assembly electrically connected to the PLC controller 13 is embedded and fixed on the right side of the bottom of the cover plate 17. The pressure-controlled extrusion assembly is located above the right-side feeding hole 4 and is adapted to its inner side. The left side of the reactor 1 is in movable contact with a slag collecting box located below the discharge pipe 6. The pressure-controlled extrusion assembly is used to be controlled by the PLC controller 13 to squeeze the plant solid slag in the right-side feeding hole 4, so that the residual liquid in the plant solid slag is effectively squeezed out through the filter plate 5 and added to the reactor 1 through the addition pipe 101 for concentration. The pressure-controlled extrusion is used in conjunction with the two feeding holes 4 that can be rotated and used alternately, and the filtrate can be continuously squeezed and discharged. The feeding hole 4 is rotated to the left and aligned with the discharge pipe 6, so that the plant solid slag after the filtrate is squeezed can be automatically discharged. The slag collecting box is used to collect the solid slag discharged from the discharge pipe 6.

[0028] Specifically, the feed rotary drive assembly includes a feed pipe 10 movably sleeved in the circular tube 7, and a cover plate 17 rotatably sleeved on the feed pipe 10, wherein a circular hole is opened on the top of the cover plate 17, and a bearing is fixedly sleeved in the circular hole.

The servo motor 12 is used to drive the gear 11 on the left to rotate, and the gear 11 on the left drives the feed pipe 10 to rotate through the gear 11 on the right, and the feed pipe 10 drives the circular swivel seat 3 to rotate to perform the cyclic alternating utilization of the two feeding holes 4.

[0029] Furthermore, the pressure-controlled extrusion assembly includes an electric push rod 14 embedded and fixed on the right side of the bottom of the cover plate 17, the protruding end of the electric push rod 14 is fixedly connected to a pressure sensor 16, and a pressure block 15 is fixedly installed on the bottom of the pressure sensor 16, wherein the top of the pressure block 15 is provided with a groove, and the bottom inner wall of the groove is fixedly connected to the bottom of the pressure sensor 16, and the pressure block 15 is located above the material hole 4 on the right and adapted to the inner side thereof. The electric push rod 14 and the pressure sensor 16 are both electrically connected to the PLC controller 13; the electric push rod 14, the pressure sensor 16 and the pressure block 15 are arranged to cooperate and are controlled by the PLC according to the extrusion requirements. The device 13 presets the pressure value for controlling the electric push rod 14 to start and reset in the reverse direction. When the electric push rod 14 is started in the forward direction, it drives the pressure block 15 downward to squeeze the plant solid residue in the right side of the feeding hole 4 through the pressure sensor 16. The pressure sensor 16 detects the pressure and transmits the pressure value to the PLC controller 13. When the preset value is reached, the PLC controller 13 controls the electric push rod 14 to start and reset in the reverse direction. After the two feeding holes 4 rotate alternately, the pressure control and filtrate extrusion work is performed again. The solid residue that is squeezed on the right side and rotates to the left side is automatically discharged downward through the discharge pipe 6. And so on, the effect of continuously squeezing the filtrate and discharging the plant solid residue is achieved.

[0030] The method of using this embodiment is as follows: when in use, the plant liquid and solid debris are poured into the feed pipe 10 as a whole, and the pressure value for controlling the electric push rod 14 to start and reset in the reverse direction is pre-set using the PLC controller 13 according to the extrusion requirements. The servo motor 12 is controlled to rotate half a circle after the electric push rod 14 is reset, and the plant liquid and solid debris fall downward into the circular tube 7, and then are discharged into the right-side material through the guide hole 9 into the right-side material through hole 4. The liquid passes through the filter plate 5 downward and is discharged into the reactor 1 through the addition pipe 101 for concentration. The other specific components and structures of the concentrator body and the principle of heating, condensing and concentrating the plant liquid are prior art. In addition, this composition and technology have also been disclosed in the above-mentioned existing public technology and are the same as those thereof, so they will not be elaborated on again.

[0031] The personnel starts the electric push rod 14 in the forward direction so that it drives the pressure block 15 to move downward through the pressure sensor 16. The pressure block 15 moves downward into the material passage hole 4 on the right and is squeezed with the plant solid residue. Under the squeezing force, the liquid remaining in the plant solid residue is effectively squeezed out through the filter plate 5. The pressure sensor 16 detects the squeezing force applied by the electric push rod 14 in real time and transmits it to the PLC controller 13 pressure value. When the preset pressure value is reached, the PLC controller 13 controls the electric push rod 14 to start in the reverse direction to reset, so as to drive the pressure block 15 to rise and reset. After resetting, the PLC controller 13 controls the servo motor 12 to start half a circle. The servo motor 12 drives the gear 11 on the left to rotate half a circle. The gear 11 on the left drives the feed pipe 10 to rotate half a circle through the gear 11 on the right. The feed pipe 10 drives the circular swivel 3 to rotate half a circle. The circular swivel 3 drives the two through holes 4 to rotate half a circle. The material hole 4 rotates and exchanges positions for alternate use. The material hole 4 rotating from the right to the left also drives the squeezed solid slag to rotate to the discharge pipe 6 on the left. The solid slag is automatically discharged downward through the discharge pipe 6 and falls into the slag collection box for collection. At this time, the liquid and plant solid slag in the feed pipe 10 are discharged to the right into the material hole 4 on the right again. The personnel can start the electric push rod 14 again to perform the squeezing work, and so on, to achieve the effect of continuously squeezing the filtrate of the plant solid slag and automatically discharging the slag. By rotating and alternating to automatically squeeze the filtrate and automatically discharge the slag, the effect of quick and effective integrated processing of the liquid remaining in the plant solid slag during concentration is achieved, reducing the waste of resources, and there is no need for personnel to remove the solid slag separately after squeezing. It is only necessary to simply start the electric push rod 14 to form an integrated extrusion, rotation alternation and slag discharge work, which is convenient to operate and easy to use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
