Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, specifically to a device for an underwater enclosed pellet mill. Background Technology

[0002] Granulators are used in industries such as pharmaceuticals, food, instant powders, chemicals, and solid beverages. They can be used to granulate well-mixed materials, and are particularly suitable for materials with high viscosity. In pesticide production, granulators are needed to agglomerate pesticide powder into granules.

[0003] There are many types of granulators on the market, but existing granulators have relatively simple functions. When using fluidized bed technology to granulate pesticide powder, it is difficult to treat the gases generated during the production process, resulting in the direct discharge of gases containing odorous impurities. This not only affects the granulation effect of pesticides but also the health of production workers. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figs. 1-3In this embodiment of the present invention, an underwater enclosed pelletizer includes a hopper and a water tank 26. The bottom of the hopper has a discharge port 2, and a connecting pipe 3 is fixedly connected inside the discharge port 2. An extrusion pipe 4 is fixedly connected to the connecting pipe 3. A rotating shaft 6 is rotatably connected inside the extrusion pipe 4, and a spiral blade 8 is fixedly connected to the rotating shaft 6. An air inlet cylinder 9 is fixedly connected to the bottom of the extrusion pipe 4, and a pelletizing plate 10 is fixedly connected to the inner wall of the air inlet cylinder 9. A bolt 11 is rotatably connected inside the pelletizing plate 10 and is fixedly connected to the rotating shaft 6. A nut 12 is threadedly connected to the side of the bolt 11 away from the rotating shaft 6, and a rotary cutter 13 is fixedly connected to the nut 12. The extrusion pipe 4... A motor 7 is fixedly connected to the top, and the output shaft of the motor 7 is fixedly connected to the drive end of the rotating shaft 6. An air inlet pipe 14 is fixedly connected to the inner wall of the air inlet cylinder 9 on the side of the granulation plate 10 away from the rotating shaft 6. An air guide pipe 15 is fixedly connected to the air inlet pipe 14, and a connector 16 is connected to the air guide pipe 15. A sealing sliding cylinder 17 is slidably connected to the outer wall of the air inlet cylinder 9. A lifting cylinder 18 is fixedly connected to the bottom of the sealing sliding cylinder 17. A stop block 19 is fixedly connected to the bottom of the lifting cylinder 18. A spring 20 is installed between the stop block 19 and the bottom of the air inlet cylinder 9. A connecting frame 21 is fixedly connected to the bottom of the lifting cylinder 18, and a top rod 22 is fixedly connected to the connecting frame 21.

[0019] A sloping groove 27 is provided on one side of the water tank 26, and the sloping groove 27 cooperates with the top rod 22. A basket 28 is installed on the other side of the water tank 26, and the top of the basket 28 is lower than the bottom of the sloping groove 27.

[0020] This invention first injects high-temperature raw materials into the hopper and fills the water tank 26 with cooling water. Simultaneously, the motor 7 drives the rotating shaft 6 to rotate, which in turn drives the spiral blade 8 to rotate, thereby spinning and extruding the high-temperature raw materials entering the extrusion tube 4. The raw materials are then extruded along the holes in the granulation plate 10 to form strip-shaped materials. At the same time, the rotating shaft 6 drives the bolt 11 to rotate, which, through the threaded connection with the nut 12, drives the rotary cutter 13 to rotate. The rotating rotary cutter 13 cuts the strip-shaped raw materials extruded along the granulation plate 10 to form granules. After being cut, the granules fall into the water tank 26 under the action of gravity, where the cooling water in the water tank 26 cools and shapes the granules. The shaped granules then slide down the inclined groove 27 at the bottom of the water tank 26 under the action of gravity into the basket 28, where they are collected.

[0021] Furthermore, this invention uses spring 20 to elastically push stop 19, which in turn causes lifting cylinder 18 to elastically press down. Simultaneously, push rod 22 to push inclined groove 27 at the bottom of water tank 26, thereby limiting the relative height between lifting cylinder 18 and inclined groove 27, thus preventing particles from accumulating in lifting cylinder 18. At the same time, high-pressure gas supply equipment is connected to connector 16, and high-pressure gas is injected into air pipe 15 through high-pressure gas supply equipment. The high-pressure gas is injected into air inlet cylinder 9 through air inlet pipe 14, thereby maintaining high pressure in air inlet cylinder 9 and lifting cylinder 18, thus preventing water in water tank 26 from entering air inlet cylinder 9 and lifting cylinder 18, and thus preventing cooling water backflow. While achieving underwater sealing of raw materials, it can also accelerate the cooling of raw material particles.

[0022] In one instance of this embodiment, please refer to Figs. 1-3 The connecting pipe 3 is equipped with a control valve 5. The opening and closing of the connecting pipe 3 is controlled by the control valve 5.

[0023] In one instance of this embodiment, please refer to Figs. 1-3 A cooling cylinder 23 is fixedly connected to the outer wall of the air intake cylinder 9. A heat dissipation fin 25 is fixedly connected to the outer wall of the air intake cylinder 9 inside the cooling cylinder 23. Water guide ports 24 are provided on both sides of the cooling cylinder 23.

[0024] This invention continuously injects cooling water into the cooling cylinder 23 through the water inlet 24, and then uses the heat dissipation fins 25 to export and absorb the heat from the raw material flowing through the air inlet 9.
