During the subsequent stirring mechanism 19 reciprocatingly pushes and pulls the sliding block 16 to move forward and backward through the cylinder 6, the locking pin 13 can fully fix the cover plate 7 and the valve 8, so that the cover plate 7 and the valve 8 are stably fixed at the discharging port 3, the sealing effect of the valve 8 on the material can be ensured, and the stirring mechanism 19 can stably and effectively stir the granular material at the discharging port 3, so that the problem of stirring failure caused by loosening of the valve 8 in the stirring process is prevented. The sliding block 16 is first used as a connecting piece for the cylinder 6 to push and open and close the cover plate 7 and the valve 8, drives the valve 8 to rotate during the closing of the discharging port 3 and the subsequent discharging process, and during the material reaction stage in the desolventizing kettle, that is, during the period when the valve 8 fixes and closes the discharging port 3, the reciprocating end of the cylinder 6 is controlled by an external electric control device to reciprocate a short distance to push the sliding block 16 to reciprocate along the mounting groove 17, so as to push the sliding column 26 to reciprocate up and down under the linkage action of the wedge-shaped sliding block 20, the limiting sliding block 21, the limiting sliding groove 25 and the trapezoidal sliding block 24, and then drive the stirring blades 31 and the stirring blocks 33 to circulate the stirring of the granular material at the discharging port 3 through the spiral track 27 and the spiral thread 30, so as to effectively prevent the blockage problem caused by the accumulation of the material at the narrow outlet of the desolventizing kettle bottom, so that the material can be quickly discharged during the subsequent discharging period, the material discharging speed and production efficiency are improved, and in the process of stirring the material, an external stirring tool is not needed, the cylinder 6 and the valve 8 are fully utilized, and more equipment does not need to be installed at the desolventizing kettle bottom, so that the equipment installation space is saved, and the material accumulation at the desolventizing kettle bottom is reduced.

[0038] As a technical optimization scheme of the present application, the mounting seat 1 of the outer circle of the blanking port 3 is provided with a plurality of sunken bolt holes 4, and the blanking port 3 is fixedly connected with a ring-shaped sealing ring on the side close to the valve 8. The bolt hole 4 is used for the fixed installation of the blanking port 3 and the mounting seat 1 and the outlet of the desolventizing tank bottom, and the sealing ring provides better sealing effect for the valve 8 when closing the blanking port 3, which can effectively prevent the material from falling.

[0039] As a technical optimization scheme of the present application, the lock pin mechanism 11 includes a lock rod 12 and a lock pin 13, the lock rod 12 is slidably connected in the movable slot 10, the lock rod 12 is fixedly connected with the lock pin 13 of the stepped structure at the end close to the valve 8, the other end of the lock rod 12 penetrates out of the movable slot 10, and the other end of the lock rod 12 is threadedly connected with the locking nut 15. The lock pin mechanism 11 only acts after closing the blanking port 3 and before opening the blanking port 3, that is, the lock rod 12 and the lock pin 13 are clamped to the mounting seat 1 by the locking nut 15 to fix the cover plate 7 and the valve 8 relative to the mounting seat 1, and vice versa, the lock pin 13 is disengaged from the mounting seat 1 by reversing the locking nut 15 to reset the lock rod 12, so that the cover plate 7 and the valve 8 can be unlocked, the cover plate 7 is pulled by the air cylinder 6 to make the valve 8 disengage from the blanking port 3, so that the material can be discharged, and in the stage of fixing the cover plate 7 by the lock pin 13, the lock pin 13 can fix the cover plate 7 to prevent the reciprocating action of the stirring mechanism 19 from pulling the cover plate 7 to cause the valve 8 to disengage from the blanking port 3 and cause the material to leak.

[0040] As a technical optimization scheme of the present application, the lock rod 12 is sleeved with the first spring 14 on one side, one end of the first spring 14 is fixedly connected with the side wall of the lock pin 13, and the other end of the first spring 14 is fixedly connected with the side wall of the movable slot 10. The first spring 14 assists in resetting the lock rod 12 through the spring tension.

[0041] As a technical optimization scheme of the present application, the sliding block 16 is fixedly connected with a wedge-shaped sliding block 20 at one end of the mounting groove 17 through a connecting block, the wedge-shaped sliding block 20 is located on one side of the sliding block 16, the length of the wedge-shaped sliding block 20 is less than the length of the sliding block 16, and the wedge-shaped sliding block 20 is slidingly connected in the mounting groove 17. The wedge-shaped sliding block 20 located on one side of the sliding block 16 moves horizontally along the mounting groove 17 under the action of the air cylinder 6, and the length of the wedge-shaped sliding block 20 is less than the length of the sliding block 16, so that the space of the mounting groove 17 is fully utilized, and the lifting movement of the trapezoidal sliding block 24 is facilitated.

[0042] As a technical optimization scheme of the present application, the inclined surface of the wedge-shaped sliding block 20 is fixedly connected with a limiting sliding block 21, the mounting groove 17 is slidingly connected with a trapezoidal sliding block 24 away from the wedge-shaped sliding block 20, the trapezoidal sliding block 24 is fixedly connected with three vertically arranged guide sliding blocks on the side wall, and a limiting sliding groove 25 slidingly connected with the limiting sliding block 21 is formed in the inclined surface of the trapezoidal sliding block 24. The limiting sliding block 21 and the limiting sliding groove 25 can slide relative to each other, and the limiting sliding block 21 can also pull the limiting sliding groove 25 and the trapezoidal sliding block 24 to make the trapezoidal sliding block 24 always maintain close connection with the wedge-shaped sliding block 20, thereby realizing the conversion of the horizontal movement of the wedge-shaped sliding block 20 and the limiting sliding block 21 into the reciprocating lifting movement of the trapezoidal sliding block 24 and the sliding column 26 in the vertical direction.

[0043] As a technical optimization scheme of the present application, the inclined surface of the wedge-shaped sliding block 20 is fixedly connected with a limiting sliding block 21, the mounting groove 17 is slidingly connected with a trapezoidal sliding block 24 away from the wedge-shaped sliding block 20, the trapezoidal sliding block 24 is fixedly connected with three vertically arranged guide sliding blocks on the side wall, and a limiting sliding groove 25 slidingly connected with the limiting sliding block 21 is formed in the inclined surface of the trapezoidal sliding block 24. The limiting sliding block 21 and the limiting sliding groove 25 can slide relative to each other, and the limiting sliding block 21 can also pull the limiting sliding groove 25 and the trapezoidal sliding block 24 to make the trapezoidal sliding block 24 always maintain close connection with the wedge-shaped sliding block 20, thereby realizing the conversion of the horizontal movement of the wedge-shaped sliding block 20 and the limiting sliding block 21 into the reciprocating lifting movement of the trapezoidal sliding block 24 and the sliding column 26 in the vertical direction.

[0044] As a technical optimization scheme of the present application, the trapezoidal slider 24 is fixedly connected with a sliding column 26 near one end of the stirring blade 31, and a spiral track 27 threaded with a spiral thread 30 is formed in the outer wall of the sliding column 26. The rotating column 29 with the spiral thread 30 is driven to rotate by the sliding column 26 and the spiral track 27, thereby driving the stirring blade 31 and the stirring block 33 to rotate and stir. The matching effect of the spiral track 27 of the spiral thread 30 is common in various structures, such as a child's push-pull propeller toy. That is, the threaded connection mode with no self-locking effect is realized by the spiral thread 30 with a thread rise angle greater than a friction angle. The rotating column 29 can be driven to rotate by the lifting of the sliding column 26 to make the circular sliding block 28 move in a circular motion around the annular groove 18, thereby realizing the rotating stirring effect of the stirring blade 31.

[0045] In use, first, the mounting seat 1 is installed at the bottom outlet of the desolventizing kettle, the discharge port 3 is aligned with the bottom outlet, the rail 2 is installed away from the bottom outlet, the bolt is sequentially threaded through the bolt hole 4 and bolted with the bottom outlet, after installation, the air cylinder 6 is communicated with the external air source through the air pipe, and the electrical components are connected with the external power supply and the electrical control equipment.

[0046] The extension end of the control air cylinder 6 is extended, the sliding block 16 and the cover plate 7 are pushed to rotate, and finally the cover plate 7 and the valve disc 8 abut against the sealing ring of the discharge port 3. At this time, the air cylinder 6 is stopped, the locking nut 15 is manually rotated, the locking rod 12 and the locking pin 13 are moved along the movable groove 10, the first spring 14 is stretched under stress, and finally the stepped structure of the locking pin 13 abuts against the side wall of the mounting seat 1. That is, the mounting seat 1 is clamped by the locking pin 13, so that the cover plate 7 and the mounting seat 1 are relatively fixed. At this time, the fixed installation of the cover plate 7 and the valve disc 8 is completed.

[0047] In the desolventizing kettle, the reaction of the material and other operations are carried out, and the granular material after the reaction is accumulated at the bottom of the desolventizing kettle. The same granular material is also filled between the bottom outlet of the desolventizing kettle and the valve 8. With the progress of the reaction, the granular material accumulates over time. Before the material is released, the material at the bottom outlet is stirred. The extension of the telescopic end of the air cylinder 6 controlled by the external electric control device can push the sliding block 16, the wedge-shaped sliding block 20 and the limiting sliding block 21 to move horizontally along the mounting groove 17. When moving, the sliding block 16 gradually approaches the direction of the locking pin 13, and the guide rod 22 follows to compress the second spring 23. With the movement of the wedge-shaped sliding block 20, the limiting sliding block 21 can push the trapezoidal sliding block 24 to move vertically along the mounting groove 17 through the limiting sliding groove 25, so that the trapezoidal sliding block 24 and the sliding column 26 move towards the bottom outlet of the desolventizing kettle. In the moving process, the helical track 27 can push the helical thread 30 and the rotating column 29 to rotate around the annular groove 18 through the annular sliding block 28. When the rotating column 29 rotates, the stirring blade 31 and the stirring block 33 can stir the granular material at the bottom outlet. When the sliding block 16 slides to the limit position, that is, the second spring 23 is compressed to the limit, the telescopic end of the air cylinder 6 controlled by the external electric control device is retracted, which can push the sliding block 16, the wedge-shaped sliding block 20 and the limiting sliding block 21 to reset along the mounting groove 17. At the same time, the second spring 23 loses force and resets to push the sliding block 16 to reset. During this period, the trapezoidal sliding block 24 and the sliding column 26 are pulled away from the bottom outlet through the limiting sliding groove 25 and the limiting sliding block 21. Similarly, the helical track 27 can push the helical thread 30 and the rotating column 29 to rotate around the annular groove 18 in the opposite direction through the annular sliding block 28. The stirring blade 31 and the stirring block 33 continue to stir the granular material. After the sliding block 16 is reset, the above operation is repeated again to continuously stir the granular material. Because the locking pin 13 is locked in the mounting seat 1, the cover plate 7 is relatively fixed with the mounting seat 1. During the stirring of the material, the valve 8 will not be sealed due to the action of the air cylinder 6, and even the material will not fall off.

[0048] After the reaction of the desolventizing kettle is completed, the material is released. The locking nut 15 is manually rotated in the opposite direction. The rotation of the locking nut 15 can push the locking rod 12 and the locking pin 13 to move along the movable groove 10. The first spring 14 loses force and resets. The locking rod 12 is pulled to reset, so that the stepped structure of the final locking pin 13 is separated from the side wall of the mounting seat 1, and the final locking pin 13 is stored in one side of the movable groove 10. At this time, the locking pin 13 cannot continue to fix the cover plate 7. The telescopic end of the air cylinder 6 controlled by the external electric control device is retracted, which can pull the sliding block 16, the cover plate 7 and the valve 8 to rotate to make the valve 8 separate from the discharge port 3. At this time, the granular material can be released.

[0049] It is apparent that those skilled in the art can make various changes and modifications to the application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the application fall within the scope of the claims and their equivalents, it is intended to include them in the scope of the application.

[0050] The above description is merely preferred embodiments of the application, but the protection scope of the application is not limited thereto, and any skilled person in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the application within the technical scope disclosed by the application, which should be covered within the protection scope of the application.
