DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8, an environmentally friendly plastic granule drying device, comprising a shell 1, a drainage box 12 is provided on the shell 1, a material inlet 11 is also provided on the shell 1, a blower mechanism 2 is also provided on the shell 1, a filter mechanism 3 is also provided on the shell 1, and a debris removal mechanism 4 is also provided on the shell 1;

[0031] The hair dryer mechanism 2 includes a support column 21, on which a motor 22 is disposed, one end of the motor 22 is connected to a connecting plate 23, on which a plurality of heating rods 24 are disposed, and on which a rotating rod 25 is also disposed, the rotating rod 25 penetrates a fixed rod 27 and is provided with a fan 26, and on which a fixing plate 29 is also disposed;

[0032] The filtering mechanism 3 includes a telescopic rod 31, on which a second filter plate 32 is arranged, on which a limiting block 38 is arranged, on which a first limiting rod 34 is arranged, on which a threaded sleeve 35 is arranged, on which a stirring rope 36 is arranged, on which a second limiting rod 37 is arranged, and on which a drain plate 39 is arranged;

[0033] The impurity removal mechanism 4 comprises a third filter plate 41 , on which a impurity removal box 43 is arranged, and on which a fourth filter plate 42 is arranged.

[0034] When the device needs to be used, pour plastic particles from the feed port 11, rotate the handle 13 to drive the baffle 14 to rotate, add the plastic particles in the feed port 11 into the housing 1, and use multiple sets of telescopic rods 31 to make the second filter plate 32 move back and forth up and down, so that the plastic particles on the second filter plate 32 vibrate, and some water falls from the second filter plate 32. At the same time, the reciprocating movement of the second filter plate 32 drives the threaded sleeve 35 to move up and down while rotating, and drives the stirring rope 36 to rotate, so as to separate the plastic particles on the surface of the second filter plate 32 to prevent the plastic particles from sticking together and affecting the drying effect of the device.

[0035] At the same time, the motor 22 is turned on to rotate the rotating rod 25, driving the multiple sets of fans 26 to rotate and blow air into the housing 1. At the same time, the heating rod 24 heats the gas supplied, causing the fan 26 to blow hot air into the housing 1. At the same time, the reciprocating motion of the second filter plate 32 drives the plastic particles to vibrate. The hot air blown in during the vibration dries the plastic particles. At the same time, the plastic particles that do not meet the quality standards are blown away by the wind and blown from the third filter plate 41 into the impurity removal box 43 to separate from the groove, thereby improving the quality of the dried plastic particles and reducing the amount of excessively mixed plastic particles that do not meet the quality standards.

[0036] At the same time, the water filtered from the second filter plate 32 enters the drainage box 12 through the fixing plate 29 and leaves the device. At the same time, the water blown out by the hot air leaves the device from the fourth filter plate 42, so as to avoid the residual water in the device affecting the drying effect of the plastic particles.

[0037] In an optional embodiment: a baffle 14 is provided on the feed port 11 , a handle 13 is provided on the baffle 14 , a hole is provided on the feed port 11 , the size of the hole matches that of the handle 13 , and the size of the baffle 14 matches that of the feed port 11 .

[0038] It should be noted that when adding plastic particles, the plastic particles are added from the feed port 11 so that the plastic particles are stored in the feed port 11. By rotating the handle 13 to drive the baffle 14 to rotate, the plastic particles in the feed port 11 are separated from the feed port 11 and added to the outer shell 1 for drying. When drying, the handle 13 is rotated to drive the baffle 14 to rotate, so that the feed port 11 and the outer shell 1 are separated, so as to avoid heat from the outer shell 1 entering the feed port 11 during drying, and to avoid some plastic particles from escaping from the device from the feed port 11 during drying, so as to ensure the operation of the device.

[0039] In an optional embodiment: a first filter plate 28 is provided on the housing 1, and a hole is provided on the first filter plate 28. One end of the first filter plate 28 is connected to a second filter plate 32, and the second filter plate 32 is also provided with a hole, and the size of the hole is the same as that of the first filter plate 28.

[0040] It should be noted that the first filter plate 28 and the second filter plate 32 form a filtering device to ensure that the plastic particles do not escape from the device during vibration. At the same time, hot air enters the second filter plate 32 from the first filter plate 28 to dry the plastic particles. The holes set on the first filter plate 28 and the second filter plate 32 are of the same size to prevent the plastic particles from escaping from the device.

[0041] In an optional embodiment, the second limiting rod 37 passes through the threaded sleeve 35 , and the second limiting rod 37 also passes through the second filter plate 32 .

[0042] It should be noted that the second limit rod 37 is used to limit the movement of the threaded sleeve 35, so that the threaded sleeve 35 moves along with the reciprocating movement of the second filter plate 32, and at the same time limits the movement of the second filter plate 32, so as to avoid quality problems of the device and ensure the normal operation of the device, so that the second filter plate 32 reciprocates on a predetermined track under the restriction of the second limit rod 37, and ensures that the movement of the second filter plate 32 drives the plastic particles to vibrate, so that part of the moisture in the plastic particles falls through the holes in the second filter plate 32 and enters the fixed plate 29 and enters the drainage box 12.

[0043] In an optional embodiment: one end of the second filter plate 32 is connected to the fourth filter plate 42 , and the fourth filter plate 42 is provided with a hole, and the size of the hole is the same as that of the hole on the second filter plate 32 .

[0044] It should be noted that the second filter 32 and the fourth filter 42 form a filtering device to ensure that plastic particles do not escape from the device during vibration. At the same time, hot air escapes from the device through the fourth filter 42 to take away moisture, thereby preventing residual moisture from affecting the drying quality of the device. The holes set on the second filter 32 and the fourth filter 42 are of the same size to prevent plastic particles from escaping from the device.

[0045] In an optional embodiment: a groove is provided on the impurity removal box 43 , an end of the impurity removal box 43 away from the groove is connected to the third filter plate 41 , and a hole is provided on the third filter plate 41 .

[0046] It should be noted that when the second filter plate 32 drives the plastic particles to vibrate, hot air is blown into the first filter plate 28 to blow on the vibrating plastic particles, so that some unqualified plastic particles are blown away, detached from the device from the third filter plate 41, and enter the drainage box 12 through the groove on the impurity removal box 43, so as to screen the quality of the vibrating plastic particles, increase the practicability of the device, and avoid the output of unqualified plastic particles.

[0047] In an optional embodiment: one end of the second limiting rod 37 is connected to the drain plate 39, the drain plate 39 is designed with an inclined surface, and one end of the drain plate 39 close to the drain box 12 is slightly lower than the other end.

[0048] It should be noted that the moisture that falls from the second filter plate 32 due to vibration enters the fixed plate 29. Since the height of one end close to the drainage box 12 is slightly lower than that of the other end, the falling water moves from the fixed plate 29 to the drainage box 12 due to the gravity effect, thereby reducing the residual moisture in the device and avoiding excessive moisture remaining in the device, which affects the drying quality of the device.

[0049] In an optional embodiment, four groups of stirring ropes 36 are arranged on the threaded sleeve 35 , the four groups of stirring ropes 36 are designed with flexible materials, and the threaded sleeve 35 is engaged with the second limiting rod 37 .

[0050] It should be noted that when the second filter plate 32 moves back and forth, it drives the threaded sleeve 35 to move and rotate at the same time, and drives the stirring rope 36 to rotate, so as to separate the plastic particles on the surface of the second filter plate 32, so as to prevent the plastic particles on the surface of the second filter plate 32 from sticking to each other and affecting the drying efficiency of the device, and at the same time, to prevent the holes on the second filter plate 32 from being blocked, which would affect the falling of water into the second filter plate 32, thereby improving the practicability of the device.

[0051] In an optional embodiment: one end of the fixing plate 29 is connected to the housing 1 , and one end of the fixing plate 29 is connected to multiple groups of fixing rods 27 , and the multiple groups of fixing rods 27 are all provided with holes, the size of which is adapted to the rotating rod 25 .

[0052] It should be noted that the fixing plate 29 is connected to the fixing rod 27 and is used to fix the rotating rod 25 so that the fan 26 can operate normally to blow hot air into the first filter plate 28 to avoid damage caused by long-term use of the device.

[0053] In an optional embodiment: the first limiting rod 34 passes through the limiting block 38 , the first limiting rod 34 passes through the second filter plate 32 , and the first limiting rod 34 is connected to the telescopic rod 31 .

[0054] It should be noted that the second filter plate 32 is restricted on the second limiting rod 37 and the first limiting rod 34 during movement, so as to prevent the connecting plate 23 from being separated from the device and improve the stability of the device.

[0055] Working principle: when the device needs to be used, pour plastic particles from the feed port 11, rotate the handle 13 to drive the baffle 14 to rotate, add the plastic particles in the feed port 11 into the outer shell 1, and use multiple sets of telescopic rods 31 to make the second filter plate 32 move back and forth up and down, so that the plastic particles on the second filter plate 32 vibrate, and some water falls from the second filter plate 32. At the same time, the reciprocating movement of the second filter plate 32 drives the threaded sleeve 35 to move up and down while rotating, driving the stirring rope 36 to rotate, and separating the plastic particles on the surface of the second filter plate 32 to prevent the plastic particles from sticking together and affecting the drying effect of the device.

[0056] At the same time, the motor 22 is turned on to rotate the rotating rod 25, driving the multiple sets of fans 26 to rotate and blow air into the housing 1. At the same time, the heating rod 24 heats the gas supplied, causing the fan 26 to blow hot air into the housing 1. At the same time, the reciprocating motion of the second filter plate 32 drives the plastic particles to vibrate. The hot air blown in during the vibration dries the plastic particles. At the same time, the plastic particles that do not meet the quality standards are blown away by the wind and blown from the third filter plate 41 into the impurity removal box 43 to separate from the groove, thereby improving the quality of the dried plastic particles and reducing the amount of excessively mixed plastic particles that do not meet the quality standards.

[0057] At the same time, the water filtered from the second filter plate 32 enters the drainage box 12 through the fixing plate 29 and leaves the device. At the same time, the water blown out by the hot air leaves the device from the fourth filter plate 42, so as to avoid the residual water in the device affecting the drying effect of the plastic particles.

[0058] When adding plastic particles, add the plastic particles from the feed port 11 so that the plastic particles are stored in the feed port 11. The baffle 14 is driven to rotate by rotating the handle 13 so that the plastic particles in the feed port 11 are separated from the feed port 11 and added to the shell 1 for drying. When drying, the handle 13 is rotated to drive the baffle 14 to rotate so that the feed port 11 and the shell 1 are separated to prevent heat from entering the feed port 11 from the shell 1 during drying, and to prevent some plastic particles from separating from the device from the feed port 11 during drying, thereby ensuring the operation of the device. The first filter plate 28 and the second filter plate 32 form a filtering device to ensure that the plastic particles do not separate from the device during vibration. At the same time, hot air enters the second filter plate 32 from the first filter plate 28 to dry the plastic particles. The first filter plate 28 is used to filter the plastic particles. The holes on the sheet 28 and the second filter sheet 32 ​​are of the same size, which is used to prevent the plastic particles from escaping from the device. The second limiting rod 37 is used to limit the movement of the threaded sleeve 35, so that the threaded sleeve 35 moves with the reciprocating movement of the second filter sheet 32, and at the same time limit the movement of the second filter sheet 32, so as to avoid quality problems of the device and ensure the normal operation of the device, so that the second filter sheet 32 ​​reciprocates on a predetermined track under the restriction of the second limiting rod 37, so as to ensure that the movement of the second filter sheet 32 ​​drives the plastic particles to vibrate, so that part of the water in the plastic particles falls from the holes in the second filter sheet 32 ​​into the fixed sheet 29 and into the drainage box 12. The second filter sheet 32 ​​and the fourth filter sheet 42 form a filtering device, so as to ensure that the plastic particles do not escaping from the device during vibration. At the same time, hot air leaves the device from the fourth filter plate 42, taking away moisture to prevent residual moisture from affecting the drying quality of the device. The holes on the second filter plate 32 and the fourth filter plate 42 are of the same size to prevent plastic particles from leaving the device. When the second filter plate 32 drives the plastic particles to vibrate, hot air is blown into the first filter plate 28 to blow the vibrating plastic particles, so that some unqualified plastic particles are blown away and leave the device from the third filter plate 41. They enter the drainage box 12 from the groove on the impurity removal box 43 to screen the vibrating plastic particles by quality, thereby increasing the practicality of the device and preventing the output of unqualified plastic particles. The moisture dropped from the second filter plate 32 due to vibration enters the fixing plate 29. Due to its proximity to the drainage box 12, the plastic particles are easily damaged. The height of one end is slightly lower than that of the other end, so that the falling water moves from the fixing plate 29 to the drainage box 12 due to the effect of gravity, reducing the residual moisture in the device and avoiding excessive residual moisture in the device, which affects the drying quality of the device. When the second filter plate 32 moves back and forth, it drives the threaded sleeve 35 to move and rotate at the same time, driving the stirring rope 36 to rotate, and separating the plastic particles on the surface of the second filter plate 32, so as to avoid the plastic particles on the surface of the second filter plate 32 sticking to affect the drying efficiency of the device, and at the same time avoid the holes on the second filter plate 32 from being blocked, which affects the falling of the water in the second filter plate 32, and improves the practicality of the device. The fixing plate 29 is connected to the fixing rod 27, which is used to fix the rotating rod 25 so that the fan 26 can operate normally to blow hot air to the first filter plate 28.To avoid damage to the device due to long-term use, the second filter 32 is restricted on the second limiting rod 37 and the first limiting rod 34 during movement, preventing the connecting plate 23 from detaching from the device and improving the stability of the device.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
