Description

Technical Field

[0001] This patent relates to the field of granulation cooling technology, specifically a rotary circulating cooling device for a granulator. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. Currently, after the granulator produces the product and discharges it through the discharge hopper, it has a certain high temperature and needs to be cooled down by static cooling and air cooling. However, the dispensed granules accumulate in the container, which prevents the granules inside from being cooled down in time, increasing the cooling time and reducing work efficiency. To address this, we propose a rotary circulating cooling device for granulators. Utility Model Content

[0003] The purpose of this patent is to provide a paper roller transport rack with protective and shock-absorbing functions to solve the problems mentioned in the background art.

[0015] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0016] Please see Figure 1 , Figure 2 and Figure 3 This patent provides a technical solution: a rotary circulating cooling device for a granulator, including a discharge hopper 1, a support rod 2 fixedly installed at the bottom of the discharge hopper 1, a collection hopper 3 attached to the right end of the discharge hopper 1, a tilting mechanism at the bottom of the collection hopper 3, an mounting plate 4 on the upper side of the collection hopper 3, a mounting hole on the mounting plate 4, a vertical cylinder 5 fixedly installed on the inner wall of the mounting hole, a duct 6 fixedly installed on the top of the vertical cylinder 5, a steel mesh 7 fixedly installed on the inner wall of the vertical cylinder 5, a motor 8 installed on the top of the steel mesh 7, a first rotating shaft 9 on the bottom side of the motor 8, a fan blade 10 fixedly installed on the side wall of the first rotating shaft 9, a reducer 11 fixedly installed at the bottom end of the first rotating shaft 9, the reducer 11 fixed to the bottom of the mounting plate 4 by a connecting rod, a second rotating shaft 12 on the bottom side of the reducer 11, a stirring rod 13 fixedly installed on the side wall of the second rotating shaft 12, and the stirring rod 13 located inside the collection hopper 3;

[0017] Since the function of the fan blade 10 is to cool the granules in the collection hopper 3, it needs to rotate at high speed. The stirring rod 13 needs to stir the granules in the collection hopper 3, and the stirring speed should not be too high. Therefore, the speed of the second rotating shaft 12 can be reduced by the reducer 11.

[0018] The top four corners of the mounting plate 4 are all integrally formed with rods.

[0019] The rod on mounting plate 4 can be fixed to the indoor ceiling.

[0020] Specifically, the tilting mechanism includes a support column 14 and a housing 15. The bottom end of the support column 14 is fixed to the ground. The bottom of the housing 15 is hinged to the top left side of the support column 14. The right side wall of the housing 15 is provided with a sliding hole, in which a sliding rod 16 is slidably installed. A connecting plate 17 is fixedly installed at the left end of the sliding rod 16. A spring 18 is sleeved on the side wall of the sliding rod 16. The two ends of the spring 18 are respectively fixedly installed on the connecting plate 17 and the inner right side wall of the housing 15. The top end of the connecting plate 17 is fixedly installed at the bottom of the collecting hopper 3.

[0021] Figure 1 The spring 18 shown is in a compressed state. The compression effect of the spring 18 makes the left side of the collecting hopper 3 fit tightly against the right side of the discharging hopper 1.

[0022] Specifically, the second rotating shaft 12 includes an upper shaft 19, a lower shaft 23, and a bolt 26. The top end of the upper shaft 19 is connected to the output shaft of the reducer 11. The bottom end of the upper shaft 19 is provided with a square groove 20. The right side wall of the square groove 20 is provided with a strip hole 21. The upper and lower sides of the left side wall of the square groove 20 are provided with threaded grooves 22. The top end of the lower shaft 23 is integrally formed with a square rod 24. The square rod 24 is slidably installed in the square groove 20. The side wall of the square rod 24 is provided with a round hole 25. The bolt 26 passes through the strip hole 21 and the round hole 25 in sequence and is screwed into the threaded groove 22 on the lower side. The stirring rod 13 is fixed on the side wall of the lower shaft 23.

[0023] like Figure 1 As shown, when it is necessary to empty the granules from the collecting hopper 3, the collecting hopper 3 needs to be moved to the left and then rotated along the hinge point. The bottommost stirring rod 13 will then obstruct the rotation of the collecting hopper 3. Figure 2 The bolt 26 can be rotated to disengage it from the threaded groove 22 on the bottom side. Then, the lower shaft 23 is moved upward to screw the bolt 26 into the threaded groove 22 on the upper side, raising the position of the stirring rod 13 and avoiding obstruction to the overturning of the collection hopper 3.

[0024] Specifically, ventilation holes 27 are provided on both the front and rear side walls of the collection bucket 3.

[0025] The diameter of the vent 27 must be smaller than the particle size of the granulation, in order to discharge the airflow that enters the collection hopper 3.

[0026] Specifically, a handle 28 is fixedly installed on the outer right side wall of the collection bucket 3.

[0027] Working principle: The air inlet of the air pipe 6 can be set in the refrigeration area or the cold outdoor environment. The granulator discharges the formed granules into the collection hopper 3 through the discharge hopper 1. The motor 8 drives the fan blade 10 to rotate. The fan blade guides the airflow through the air pipe 6 to draw in air until it acts on the granules in the collection hopper 3. At the same time, the stirring rod 13 rotates to stir the granules, so that the cold air comes into contact with the granules over a large area, shortening the cooling time.

[0028] After cooling is complete, turn off the power equipment. Rotate the bolt 26 to disengage it from the threaded groove 22 on the bottom side. Then move the lower shaft 23 upward to screw the bolt 26 into the threaded groove 22 on the upper side. Raise the position of the stirring rod 13. Then, the worker holds the handle 28 and pulls the collecting hopper 3 to the right so that its left side disengages from the right side of the discharge hopper 1. Then, flip the box 15 along the hinge point between the support column 14 and the box 15 to pour out the granules in the collecting hopper 3.

[0029] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.
