Description

Technical Field

[0001] The utility model relates to the field of drying, in particular to a drying machine for recycled plastic particles. Background Art

[0002] Recycled granules are the abbreviation of recycled plastic granules. Recycled plastic granules belong to the category of plastic granules. Recycled plastics are plastics produced by recycling used new materials or waste plastics through a screw machine, and then cut into granular plastic granules by a pelletizer. When producing recycled plastic granules, cleaning is an indispensable link. A large amount of liquid often adheres to the surface of the plastic granules after cleaning. The wet plastic granules need to be dried before entering the next processing link. Plastic granule drying equipment has also come into being.

[0003] However, the existing drying equipment usually dries a bunch of plastic particles together, which is prone to uneven drying, low drying efficiency, and is very time-consuming and labor-intensive. Therefore, we need a dryer for recycled plastic particles to solve the above problems. Utility Model Content

[0005] The utility model is implemented as follows: a drying machine for recycled plastic particles comprises: a hot air blower, a ventilation duct, and a drying machine connected to an air outlet of the hot air blower through the ventilation duct.

[0006] The dryer is in the shape of a hollow cylinder, and a mesh disk is provided inside the dryer. The mesh disk is semicircular and fixedly connected to the inner wall of the dryer, and the mesh disk is distributed in layers and staggered in the dryer. A slope is provided at the bottom of the dryer, and the slope is placed below the mesh disk. A lifting cylinder and a controller are provided on the bottom surface of the dryer, and the lifting cylinder is fixedly connected to the inner bottom surface of the dryer. A rotating motor is provided on the piston rod of the lifting cylinder, and the rotating motor is placed below the slope. A rotating rod is provided on the output shaft of the rotating motor, and one end of the rotating rod is connected to the output shaft of the rotating motor. The rotating rod is provided with rotating blades, and the number of the rotating blades is the same as that of the mesh disk, and each rotating blade is placed above the mesh disk corresponding to it.

[0020] Embodiment 1: Figure 1 , Figure 2 , Figure 3 A drying machine for recycled plastic particles is shown, the device comprising: a hot air blower 1, a ventilation duct 12, and a drying machine 2 connected to the air outlet of the hot air blower 1 through the ventilation duct 12.

[0021] The dryer 2 is a hollow cylindrical shape, and a mesh disk 24 is provided inside the dryer 2. The mesh disk 24 is semicircular and fixedly connected to the inner wall of the dryer 2. The mesh disk 24 is layered and staggered in the dryer 2. A slope 27 is provided at the bottom of the dryer 2, and the slope 27 is placed below the mesh disk 24. A lifting cylinder 4 and a controller 5 are provided on the bottom surface of the dryer 2. The lifting cylinder 4 is fixedly connected to the inner bottom surface of the dryer 2. A rotating motor 3 is provided on the piston rod of the lifting cylinder 4, and the rotating motor 3 is placed below the slope 27. A rotating rod 26 is provided on the output shaft of the rotating motor 3, and one end of the rotating rod 26 is connected to the output shaft of the rotating motor 3. A rotating leaf 25 is provided on the rotating rod 26. The number of the rotating leaf 25 is the same as that of the mesh disk 24, and each rotating leaf 25 is placed above the mesh disk 24 corresponding to it. Each mesh disk 24 has a rotating blade 25 above the other semicircle corresponding to it. When the bottom lifting cylinder 4 is extended, the rotating blade 25 will have a certain distance from the surface of the mesh disk 24 when rotating, so that a part of the plastic particles can be spread on the mesh disk 24 for drying. The thickness of the plastic left is relatively appropriate, which can ensure that the plastic particles are heated more evenly and dried more fully during drying. The dryer 2 is equipped with a monitoring sensor inside, which can monitor and adjust the temperature, humidity and time parameters in the drying process in real time, so as to realize the precise control of the drying process. Through the controller 5, we can flexibly adjust the drying parameters on the display screen 51 according to the type, humidity and drying requirements of the plastic particles, so as to achieve the best drying effect. When the drying is completed, the lifting cylinder 4 is retracted, so that the side of the rotating blade 25 is in contact with the surface of the mesh disk 24 during the rotation process, and all the dried plastic particles are driven to the bottom slope 27. Finally, the controller 5 controls the outlet valve 22 to open the valve, so that the dried plastic particles can enter the next process. The mesh on the mesh disk 24 is much smaller than the size of the plastic particles, and no plastic particles will fall into it to cause blockage. A ventilation net 13 is provided at the connection between the ventilation duct 12 and the dryer 2. A feed port 21 is provided at the top of the dryer 2. A support leg 23 is provided at the bottom of the dryer 2. An outlet valve 22 is provided at the connection between the tail of the slope 27 and the dryer 2. A display screen 51 is provided on the dryer 2. The display screen 51 and the rotating motor 3 are electrically connected to the controller 5.

[0022] Working principle: First, pour the plastic particles to be dried into the dryer 2 through the feed port 21. According to the set parameters, the lifting cylinder 4 is lifted to the set height, so that the rotating blades are separated from the surface of the mesh disk 24 by a certain distance, and the plastic particles are spread flat on the mesh disk 24. The excess plastic particles are driven into the lower layer and laid down layer by layer. After the laying is completed, the controller 5 controls the hot air blower 1 to transport hot air into the dryer 2 to dry the plastic particles inside. When the drying is completed, the lifting cylinder 4 retracts, so that the rotating blades 25 are in contact with the surface of the mesh disk 24 during the rotation, and all the dried plastic particles are driven to the bottom slope 27. Finally, the controller 5 controls the outlet valve 22 to open the valve to allow the dried plastic particles to enter the next process.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
