Description

Technical Field

[0001] This invention relates to the field of pesticide granulation technology, and in particular to a rotary extrusion granulator and its granulation process. Background Technology

[0002] Rotary extrusion granulators use high-speed rotation to expel material from a die cylinder, but the friction between the die cylinder and the extrusion rollers generates high temperatures. Excessive temperature can have a thermal effect on the drug, thus affecting its efficacy. In existing technologies, an external blower ring is used to cool the outer wall of the die cylinder. However, because the die cylinder continuously discharges material, the extruded material blocks the outer wall of the cylinder, hindering heat dissipation and cooling. Furthermore, the blown-out cold air can disperse the extruded material. Summary of the Invention

[0016] One end of the material blocking component is fixedly connected to the inner wall of the mounting box, and the bottom of the material blocking component is in contact with the top of the turntable;

[0017] An internal gear ring is fixed to the bottom of the turntable, and a gear three meshes with the inner side of the internal gear ring. A rotating shaft one is fixed to the bottom of the gear three, and a gear two is fixed to the bottom end of the rotating shaft one.

[0018] The rotating shaft is rotatably connected to the bottom of the mounting box.

[0019] Furthermore, the drug efficacy protection mechanism also includes a guide rod fixed to the inner wall of the bottom of the mounting box, the guide rod being sleeved inside the mold cylinder;

[0020] The reciprocating screw is rotatably connected to the bottom of the mounting box, and a gear four is fixed at the bottom end of the reciprocating screw.

[0021] Furthermore, the first drug efficacy protection mechanism also includes a second rotating shaft that is rotatably connected to the bottom of the mounting box. A fifth gear is installed at the bottom end of the second rotating shaft, and the fifth gear meshes with the second gear and the fourth gear.

[0022] The top end of the second rotating shaft is fixed with an extrusion wheel. The extrusion wheel is sleeved inside the mold cylinder, and its edge is in contact with the inner wall of the mold cylinder. The height of the extrusion wheel is half that of the mold cylinder.

[0023] The material base plate is rotatably connected to the outside of the second rotating shaft. The material base plate is sleeved inside the mold cylinder, and its edge is in contact with the inner wall of the mold cylinder.

[0024] A sleeve is fixed to the bottom of the material base plate, and the bottom of the sleeve is fixedly connected to the bottom inner wall of the mounting box. The rotating shaft is sleeved inside the sleeve.

[0025] The first and second annular jet pipes are connected to an external air supply source via pipelines, and the first and second annular jet pipes are fixedly connected to the mounting box.

[0026] Furthermore, the bottom of the square rod is fixedly connected to the top of the second rotating shaft;

[0027] Multiple L-shaped plates are respectively fitted into the blade gaps of the extrusion roller;

[0028] The cooling cylinder is connected to an external water source via a pipeline.

[0029] Furthermore, the drive mechanism includes a motor fixed to the bottom of the mounting box, and a gear one is fixed to the output end of the motor, which meshes with a gear two.

[0030] Furthermore, a controller is fixed to one side of the mounting box, and the controller is electrically connected to the motor.

[0031] A granulation process for a rotary extrusion granulator, applicable to the rotary extrusion granulator described above, includes the following steps:

[0032] Step 1: Start the motor through the controller to drive gear 1 to rotate, and the rotation of gear 1 will drive gears 2, 5 and 4 to rotate;

[0033] Step 2: Add the material with a certain temperature into the cooling cylinder, and then the material enters the mold cylinder. The cooling cylinder cools the material. Gear 5 drives shaft 2 to rotate the extrusion wheel. The rotating extrusion wheel pushes the material in the mold cylinder to move. The material close to the cylinder wall is extruded from the material hole by the edge of the extrusion wheel to form the mold.

[0034] At the same time, the rotation of gear four drives the reciprocating screw to rotate, and the rotation of the reciprocating screw causes the mold cylinder to move up and down.

[0035] The mold cylinder is divided into upper and lower sections. The upper section is in direct contact with the material. As this section moves upward, it gradually loses contact with the extrusion roller. The outer wall comes into contact with the air sprayed from the first annular jet pipe, and the inner wall comes into contact with the cooled material. The inner and outer walls of this section are cooled simultaneously. Before the lower section rises to a position where it does not come into contact with the extrusion roller, it is cooled by the second annular jet pipe. After this section moves upward, the inner wall comes into contact with the extrusion roller and the material is extruded. When the mold cylinder rises to the top of the reciprocating screw, it moves downward. The cooled upper section moves downward and comes into contact with the extrusion roller, and the lower section moves downward and loses contact with the extrusion roller. Then it comes into contact with the gas sprayed from the second annular jet pipe for cooling.

[0036] At the same time, as the mold cylinder moves up and down, the cooling cylinder moves synchronously, and drives the mounting ring, L-shaped plate and sleeve plate to move up and down. During the up and down movement of the L-shaped plate, the material in the gap of the extrusion wheel blades is continuously pushed upward, and the material cooled by the cooling cylinder continuously fills the gap. This collaborative mechanism enables the material to be continuously exchanged between the upper and lower areas, cooling the mold cylinder and extrusion wheel.

[0037] Step 3: The formed material falls onto the surface of the turntable. Gear 2 rotates, driving shaft 1 and gear 3 to rotate. Gear 3 then drives the internal gear ring and the turntable to rotate synchronously. The turntable pushes the surface material towards the discharge port. After being blocked by the material blocking component, the material slides along the material blocking component into the discharge port and is finally discharged from the installation box.

[0038] Compared with existing technologies, the beneficial effects of this invention are:

[0039] 1. This invention divides the mold cylinder into upper and lower sections by installing a drug efficacy protection mechanism. The upper section is in direct contact with the material. As this section moves upward, it gradually loses contact with the extrusion roller. The outer wall contacts the air ejected from the annular jet pipe, and the inner wall contacts the cooled material. This simultaneously cools the inner and outer walls of the section, preventing continuous operation from causing temperature rise and affecting drug efficacy. Before the lower section rises to a position where it does not contact the extrusion roller, it is cooled by the annular jet pipe. After this section moves upward, the inner wall contacts the extrusion roller and the material is extruded. When the mold cylinder rises to the top of the reciprocating screw, it moves downward. The cooled upper section moves downward and contacts the extrusion roller, while the lower section moves downward and loses contact with the extrusion roller. Then, it contacts the gas ejected from the annular jet pipe for cooling. By following the above steps, while ensuring discharge efficiency, the invention avoids the situation where continuous friction of the mold cylinder causes temperature rise and affects drug efficacy, thus ensuring both efficiency and drug efficacy of the material.

[0040] 2. In this invention, when the mold cylinder moves up and down in a reciprocating motion, the cooling cylinder moves synchronously, driving the mounting ring, L-shaped plate, and sleeve plate to move up and down. During the up and down movement of the L-shaped plate, the material in the gap between the extrusion wheel blades is continuously pushed upwards, while the material cooled by the cooling cylinder continuously fills the gap. This synergistic mechanism promotes continuous material exchange between the upper and lower areas, preventing the mold cylinder and extrusion wheel from overheating and affecting the efficacy of the material, while also ensuring that the cooled material is continuously replenished to the extrusion area, thus ensuring stable temperature during the extrusion process. This significantly enhances the overall cooling effect and effectively reduces frictional heat loss. The system forms a highly efficient cycle in the reciprocating motion, controlling the working temperature of the extrusion wheel and mold cylinder within a safe threshold, while protecting the active ingredients of the material from high-temperature damage, and minimizing efficacy loss during continuous production.

[0075] A controller is fixed on one side of the mounting box 13, and the controller is electrically connected to the motor 51.

[0076] A granulation process for a rotary extrusion granulator, applicable to the aforementioned rotary extrusion granulator, includes the following steps:

[0077] Step 1: Start motor 51 through the controller to drive gear 1 52 to rotate. The rotation of gear 1 52 drives gear 2 27, gear 5 39 and gear 4 33 to rotate.

[0078] Step 2: Add the material with a certain temperature into the cooling cylinder 41, and then the material enters the mold cylinder 31. The cooling cylinder 41 cools the material. Gear 5 39 drives the rotating shaft 2 37 to rotate the extrusion wheel 38. The rotating extrusion wheel 38 pushes the material in the mold cylinder 31 to move. The material near the cylinder wall is extruded from the material hole by the edge of the extrusion wheel 38 to form the material.

[0079] At the same time, the rotation of gear 33 drives the reciprocating screw 32 to rotate, and the rotation of the reciprocating screw 32 causes the mold cylinder 31 to move up and down;

[0080] The mold cylinder 31 is divided into upper and lower sections. The upper section is in direct contact with the material. As this section moves upward, it gradually loses contact with the extrusion roller 38. The outer wall comes into contact with the air sprayed from the annular jet pipe 310, and the inner wall comes into contact with the cooled material. The inner and outer walls of this section are cooled simultaneously. Before the lower section rises to the position where it does not come into contact with the extrusion roller 38, it is cooled by the annular jet pipe 311. After this section moves upward, the inner wall comes into contact with the extrusion roller 38 and the material is extruded. When the mold cylinder 31 rises to the top end of the reciprocating screw 32, it moves downward. The cooled upper section moves downward and comes into contact with the extrusion roller 38, and the lower section moves downward and loses contact with the extrusion roller 38. Then it comes into contact with the gas sprayed from the annular jet pipe 311 for cooling.

[0081] At the same time, when the mold cylinder 31 moves up and down, the cooling cylinder 41 moves synchronously and drives the mounting ring 42, L-shaped plate 43 and sleeve plate 44 to move up and down. During the up and down movement of the L-shaped plate 43, it continuously pushes the material in the gap of the extrusion wheel 38 blades upward. At the same time, the material cooled by the cooling cylinder 41 continuously fills the gap. This collaborative mechanism enables the material to continuously exchange between the upper and lower areas, cooling the mold cylinder 31 and the extrusion wheel 38.

[0082] Step 3: The formed material falls onto the surface of the turntable 23. The rotation of gear 27 drives the rotation of shaft 1 26 and gear 3 25. Gear 3 25 then drives the internal gear ring 28 and the turntable 23 to rotate synchronously. The turntable 23 pushes the surface material toward the discharge port 14. After being blocked by the material blocking component 24, the material slides along the material blocking component 24 into the discharge port 14 and is finally discharged from the installation box 13.

[0083] Working principle:

[0084] The controller starts motor 51, which drives gear 1 52 to rotate. The rotation of gear 1 52 drives gear 2 27, gear 5 39 and gear 4 33 to rotate.

[0085] External feeding equipment adds materials with a certain temperature into the cooling cylinder 41. Then the materials enter the mold cylinder 31. The cooling cylinder 41 cools the materials. Gear 5 39 drives shaft 2 37 to rotate the extrusion wheel 38. The rotating extrusion wheel 38 pushes the materials in the mold cylinder 31 to move. The materials close to the cylinder wall are extruded from the material hole by the edge of the extrusion wheel 38 to form the material.

[0086] The formed material falls onto the surface of the turntable 23. The rotation of gear 27 drives the rotation of shaft 26 and gear 25. Gear 25 then drives the internal gear ring 28 and the turntable 23 to rotate synchronously. The turntable 23 pushes the surface material toward the discharge port 14. After being blocked by the material blocking member 24, the material slides along the material blocking member 24 into the discharge port 14 and is finally discharged from the mounting box 13.

[0087] When the material has high hardness, in order to ensure a high discharge speed, the temperature of the mold cylinder 31 will rise due to friction. The high temperature will have a thermal effect on the drug, thereby affecting the drug's efficacy.

[0088] The rotation of gear 43 drives the reciprocating screw 32 to rotate, and the rotation of the reciprocating screw 32 causes the mold cylinder 31 to move up and down, and the mold cylinder 31 moves up and down reciprocally.

[0089] The mold cylinder 31 is divided into upper and lower sections. The upper section is in direct contact with the material. As this section moves upward, it gradually loses contact with the extrusion roller 38. The outer wall comes into contact with the air sprayed from the annular jet pipe 310, and the inner wall comes into contact with the cooled material. This simultaneously cools the inner and outer walls of the section, preventing continuous operation from causing a temperature rise that could affect the efficacy of the medicine. Before the lower section rises to a position where it does not come into contact with the extrusion roller 38, the annular jet pipe 311 cools it. After this section moves upward, the inner wall comes into contact with the extrusion roller 38 to extrude the material. When the mold cylinder 31 rises to the top of the reciprocating screw 32, it moves downward. The cooled upper section moves downward to contact the extrusion roller 38, and the lower section moves downward to lose contact with the extrusion roller 38. Then, it comes into contact with the gas sprayed from the annular jet pipe 311 for cooling. By following the above steps, while ensuring the discharge efficiency, the continuous friction of the mold cylinder 31 can prevent a temperature rise that could affect the efficacy of the medicine, thus ensuring both efficiency and the efficacy of the material.

[0090] As the mold cylinder 31 reciprocates up and down, the cooling cylinder 41 moves synchronously, driving the mounting ring 42, L-shaped plate 43, and sleeve plate 44 to move up and down as well. During the up-and-down movement of the L-shaped plate 43, the material in the gaps between the blades of the extrusion roller 38 continuously moves upwards, while the material cooled by the cooling cylinder 41 continuously fills the gaps. This synergistic mechanism promotes continuous material exchange between the upper and lower areas, preventing the mold cylinder 31 and extrusion roller 38 from overheating and affecting the efficacy of the material, while also ensuring a continuous supply of cooled material to the extrusion area, guaranteeing stable temperature during the extrusion process. This significantly enhances the overall cooling effect and effectively reduces frictional heat loss. The system forms a highly efficient cycle during reciprocating motion, controlling the working temperature of the extrusion roller 38 and mold cylinder 31 within safe thresholds, while protecting the active ingredients of the material from high-temperature damage, minimizing efficacy loss during continuous production.

[0091] In addition, to ensure that the L-shaped plate 43 always corresponds to the blade gap, the rotating shaft 37 drives the square rod 45, the sleeve plate 44 and the L-shaped plate 43 to rotate synchronously when rotating, so that the L-shaped plate 43 and the gap of the extrusion wheel 38 always remain in position, thereby achieving continuous operation of extrusion and cooling at the same time.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A rotary extrusion granulator according to claim 7, characterized in that, A controller is fixed on one side of the mounting box (13), and the controller is electrically connected to the motor (51).

9. A granulation process for a rotary extrusion granulator, applicable to the rotary extrusion granulator of claim 8, characterized in that, Includes the following steps: Step 1: Start the motor (51) through the controller to drive gear 1 (52) to rotate. The rotation of gear 1 (52) drives gear 2 (27), gear 5 (39) and gear 4 (33) to rotate. Step 2: Add the material with a certain temperature into the cooling cylinder (41), and then the material enters the mold cylinder (31). The cooling cylinder (41) cools the material. Gear 5 (39) drives shaft 2 (37) to rotate the extrusion wheel (38). The rotating extrusion wheel (38) pushes the material in the mold cylinder (31) to move. The material close to the cylinder wall is extruded from the material hole by the edge of the extrusion wheel (38) to form the material. At the same time, the rotation of gear four (33) drives the reciprocating screw (32) to rotate, and the rotation of the reciprocating screw (32) causes the mold cylinder (31) to move up and down; The mold cylinder (31) is divided into upper and lower sections. The upper section is in direct contact with the material. When the upper section moves up, it gradually releases contact with the extrusion roller (38). The outer wall contacts the air sprayed from the first annular jet pipe (310), and the inner wall contacts the cooled material. At the same time, the inner and outer walls of this section are cooled. Before the lower section rises to the position where it does not contact the extrusion roller (38), it is cooled by the second annular jet pipe (311). After the lower section moves up, the inner wall contacts the extrusion roller (38) and the material is extruded. When the mold cylinder (31) rises to the top end of the reciprocating screw (32), it moves down. The cooled upper section moves down and contacts the extrusion roller (38), and the lower section moves down and releases contact with the extrusion roller (38). Then it contacts the gas sprayed from the second annular jet pipe (311) for cooling. At the same time, when the mold cylinder (31) moves up and down, the cooling cylinder (41) moves synchronously and drives the mounting ring (42), L-shaped plate (43) and sleeve plate (44) to move up and down. During the up and down movement of the L-shaped plate (43), it continuously pushes the material in the gap of the extrusion wheel (38) blades to move upward. At the same time, the material cooled by the cooling cylinder (41) continuously fills the gap. This collaborative mechanism enables the material to continuously exchange between the upper and lower areas, cooling the mold cylinder (31) and the extrusion wheel (38). Step 3: The formed material falls onto the surface of the turntable (23). The rotation of gear 2 (27) drives the rotation of shaft 1 (26) and gear 3 (25). Gear 3 (25) then drives the internal gear ring (28) and the turntable (23) to rotate synchronously. The turntable (23) pushes the surface material toward the discharge port (14). After being blocked by the material blocking component (24), the material slides along the material blocking component (24) into the discharge port (14) and is finally discharged from the installation box (13).
