The horizontal reciprocating motion of the push plate rack can squeeze and relax the heat transfer liquid in the second heating chamber, so as to realize rapid reciprocating motion of the heat transfer liquid in the second heating chamber. The first heating chamber and the second heating chamber are connected. When squeezed, the heat transfer liquid in the second heating chamber flows rapidly toward the first heating chamber. After the heat transfer liquid enters the first heating chamber, the heat transfer liquid impacts the first heating chamber at the bottom of the feed rack. When the push plate rack releases the heat transfer fluid in the second heating chamber, the pressure of the heat transfer fluid in the second heating chamber decreases, and the heat transfer fluid flows back to the second heating chamber. The heat transfer fluid at the top of the inner side of the first heating chamber flows back to the third heating chamber, and then flows back from the third heating chamber to the inner side of the second heating chamber.

[0018] 2. The present invention configures the push plate frame to be composed of a push plate and a third connecting rod, the first connecting rod drives the third connecting rod to perform horizontal reciprocating motion. When the third connecting rod moves toward the side close to the feed rack, the first plug block on the support plate on the side of the third connecting rod away from the feed rack is inserted into the first slot, and the second plug block is inserted into the second slot. After the second plug block is inserted into the second slot, the second plug block pushes the support bar outward, and the support bar pushes the flexible pad outward to ensure that the flexible pad is sealed between the push plate and the inner wall of the second heating chamber, which can effectively ensure the sealing of the push plate when it moves toward the feed rack, and prevent the heat transfer oil from passing through the push plate frame to move to the other side of the second heating chamber under the action of the extrusion force, thereby ensuring that the heat transfer oil all moves toward the second heating chamber toward the feed rack; when the third connecting rod moves to the side away from the feed rack, the third connecting rod The first plug block on the support plate on the side of the rod away from the feed rack is pulled out of the first slot, and the second plug block is pulled out of the second slot. After the second plug block is pulled out of the second slot, the support bar is reset and drives the flexible pad to reset; the first plug block on the support plate on the side of the third connecting rod close to the feed rack is inserted into the first slot, and the second plug block is inserted into the second slot. After the second plug block is inserted into the second slot, the second plug block pushes the support bar outward, and the support bar pushes the flexible pad outward to ensure that the flexible pad is sealed between the push plate and the inner wall of the second heating chamber, which can effectively ensure the sealing of the push plate when it moves away from the feed rack, and prevent the heat transfer oil from passing through the push plate rack under the action of the extrusion force and moving to the other side of the second heating chamber, ensuring that the heat transfer oil moves all toward the second heating chamber toward the feed rack, which can effectively ensure the normal movement of the push plate while ensuring the sealing of the push plate.

[0033] The specific implementation method is as follows: when in use, by setting the first heating chamber 5, the second heating chamber 6, the annular guide cylinder 12, the third heating chamber 13, the push plate frame 14, the first connecting rod 20, and the second connecting rod 22, the servo motor 10 is turned on, the servo motor 10 drives the support rod 3 and the worm 15 to rotate, the support rod 3 drives the spiral conveying frame 4 to rotate, the rotation of the worm 15 drives the worm wheel 16 to rotate, the worm wheel 16 drives the support shaft 17 to rotate, the support shaft 17 drives the first gear 18 to rotate, and the second gear 18 drives the first gear 18 to rotate. A gear 18 is meshed with a second gear 19, and the second gear 19 rotates. One end of the first connecting rod 20 performs a circular motion along the top of the second gear 19, and the other end of the first connecting rod 20 drives the push plate frame 14 to perform a linear reciprocating motion. The push plate frame 14 performs a horizontal reciprocating motion inside the second heating chamber 6. The horizontal reciprocating motion of the push plate frame 14 can squeeze and relax the heat transfer liquid inside the second heating chamber 6, so as to achieve a rapid reciprocating motion of the heat transfer liquid inside the second heating chamber 6. The first heating chamber 5 and the second heating chamber 6 are connected, and the second heating chamber 6 is connected. The heat-conducting liquid in the heat chamber 6 flows rapidly toward the first heating chamber 5 when being squeezed. After the heat-conducting liquid enters the first heating chamber 5, the heat-conducting liquid impacts from the first heating chamber 5 at the bottom of the feed rack 2 into the third heating chamber 13 of the annular guide cylinder 12, filling the internal space of the third heating chamber 13. After the internal space of the third heating chamber 13 is filled, it is discharged from the third heating chamber 13 into the first heating chamber 5 located at the upper part of the feed rack 2, which can effectively enhance the mixed flow interaction effect of the heat-conducting liquid in the first heating chamber 5 and the second heating chamber 6. When the push plate rack 14 releases the heat transfer liquid in the second heating chamber 6, the heat transfer liquid pressure in the second heating chamber 6 decreases, and the heat transfer liquid flows back to the second heating chamber 6. The heat transfer liquid at the top of the inner side of the first heating chamber 5 flows back to the third heating chamber 13, and then flows back from the third heating chamber 13 to the bottom of the inner side of the first heating chamber 5. With the continuous rotation of the worm 15, the heat transfer liquid continuously reciprocates and alternately mixes, which can effectively enhance the heat distribution uniformity of the heat transfer liquid in the first heating chamber 5 and the second heating chamber 6, thereby enhancing the heat transfer uniformity.

[0034] The material to be processed is put into the feed rack 2 from the feed port 11 on the top of the feed rack 2, and the material enters the inside of the feed rack 2. At the same time, the material moves to the inner bottom of the feed rack 2 after passing through the annular guide cylinder 12, and then enters the inside of the screw press body 1. The heating wire heats the heat transfer liquid. The first heating chamber 5 heats the material inside the feed rack 2. The annular guide cylinder 12 guides the material, which can effectively increase the movement path of the material inside the feed rack 2 and increase the contact area between the material and the feed rack 2. The third heating chamber 13 heats the material inside the annular guide cylinder 12, which can effectively enhance the heating effect of the material during feeding. The heat transfer liquid in the second heating chamber 6 heats the outside of the screw press body 1, which can effectively heat the material during the screw pressing process, and the heating effect of the material is better.

[0035] During the process of the spiral conveying frame 4 performing spiral pressing and conveying on the material, the material is conveyed from the feed frame 2 to the discharge port 9. When the material is conveyed to the position of the support sleeve 24, the material pushes the support sleeve 24 forward, and the support sleeve 24 moves toward the hemispherical guide shell 30. The support ring 26 moves with the support sleeve 24, and the support sheet 27 moves with the support sleeve 24. The support sheet 27 compresses the spring 28, and the support ring 26 pushes the cutter 25 upward. The cutter 25 rotates along the connecting shaft 29, and the cutter 25 gradually moves upward from the inclined state to the vertical state. The cutter 25 divides the material, which can effectively avoid To avoid the material from being compacted and adhered after being compressed, the material moves toward the hemispherical guide shell 30 after the cutting knife 25 cuts the material, and the hemispherical guide shell 30 guides the material, and the hemispherical guide shell 31 guides the material outside the hemispherical guide shell 30. The material moves along the hemispherical guide shell 30 and the hemispherical guide shell 31, which can effectively ensure that the material quickly enters the discharge port to avoid blockage; the torsion spring provides torsion support for the cutting knife 25, which can effectively ensure the normal reset of the cutting knife 25, and the spring 28 rebounds through the support sheet 27 to drive the support sleeve 24 and the support ring 26 to reset;

[0036] The support shaft 17 drives the first gear 18 to rotate, and the first gear 18 is meshed with the third gear 21, driving the third gear 21 to rotate. The third gear 21 drives one end of the second connecting rod 22 to perform circular motion, and the other end of the second connecting rod 22 drives the baffle 23 to perform horizontal reciprocating motion. The baffle 23 performs horizontal reciprocating motion on the inner side of the discharge port 9 to achieve intermittent discharge processing of the material, which can effectively ensure the residence time of the material inside the screw press body 1 and ensure the screw pressing processing effect.

[0038] The specific implementation method is as follows: when in use, the push plate frame 14 is configured to be composed of two parts, the push plate 32 and the third connecting rod 33, the first connecting rod 20 drives the third connecting rod 33 to perform horizontal reciprocating motion, and when the third connecting rod 33 moves toward the side close to the feed rack 2, the first plug block 37 on the support plate 36 on the side of the third connecting rod 33 away from the feed rack 2 is inserted into the first slot 34, the second plug block 38 is inserted into the second slot 35, and after the second plug block 38 is inserted into the second slot 35, the second plug block 37 is inserted into the second slot 35. The block 38 pushes the support bar 40 outward, and the support bar 40 pushes the flexible pad 39 outward, ensuring that the flexible pad 39 is sealed between the push plate 32 and the inner wall of the second heating chamber 6, which can effectively ensure the sealing of the push plate 32 when it moves toward the feed rack 2, and prevent the heat transfer oil from passing through the push plate rack 14 under the action of the extrusion force and moving to the other side of the second heating chamber 6, ensuring that the heat transfer oil all moves from the second heating chamber 6 to the feed rack 2; when the third connecting rod 33 moves away from the feed rack 2, the third connecting rod The first plug block 37 on the support plate 36 on the side away from the feed rack 2 is pulled out from the first slot 34, and the second plug block 38 is pulled out from the second slot 35.
