Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, and in particular to a plastic particle drying machine with a waste heat recovery function. Background Art
[0002] In the plastic processing industry, the drying of plastic particles is a crucial link. The traditional drying method mainly uses hot air drying. Although this method is simple to operate, due to the limitations of its drying principle, the drying effect for large plastic particles is not ideal, and uneven drying often occurs, which not only affects the quality of plastic particles, but also may cause various problems in subsequent processing. In addition, the thermal energy utilization rate of traditional drying methods is very low, and a large amount of thermal energy is wasted, which not only increases production costs, but also has a negative impact on the environment. In order to solve the above problems, a plastic particle dryer with waste heat recovery function is designed. Utility Model Content

[0006] Preferably, a feed port is installed on one side of the outer wall of the top cover, a bottom cover is installed at the bottom of the outer wall of the body, and a warehouse door is installed at the bottom of the bottom cover.

[0008] Preferably, the inner wall of the mounting block is provided with a cavity, and the power rod passes through the cavity of the mounting block. When the power rod rotates, it drives the mounting block to rotate. Because the overall height of the equipment is relatively high, the user can judge whether the power rod is rotating normally by observing whether the mounting block rotates.
[0009] Preferably, the tooth grooves of the power wheel are meshed with the tooth grooves of the linkage wheel, and the power wheel and the linkage wheel form an meshing transmission connection structure. Since the rotating rod and the power rod are connected through a rotating shaft, the power rod will drive the rotating rod to rotate when it rotates, so that the rotating rod drives the power wheel to rotate.

[0012] The working principle and beneficial effects of the utility model are:
[0013] 1. The utility model realizes uniform stirring of plastic particles inside the machine body through the coordinated action of components such as the power rod, the mounting block, the rotating block, and the rotating rod.

This design ensures that the plastic particles can be fully and evenly affected by the heat source. This design avoids the problem of uneven drying in traditional drying methods and improves the drying effect of plastic particles. At the same time, by observing the rotation state of the mounting block, the working state of the power rod can be quickly judged, which is convenient for daily maintenance and troubleshooting.

This design avoids the waste of heat energy and improves the utilization rate of energy. At the same time, it effectively solves the problem of excessive water vapor in heat recovery in traditional drying methods. The booster pump draws the hot steam inside the machine body into the circulation pipe, and then discharges it back into the machine body after cooling treatment, thereby realizing the continuous and efficient utilization of heat energy, thus avoiding the waste of heat energy. This structure improves the utilization rate of heat energy, reduces the waste of energy, and further improves the utilization rate of heat energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In this embodiment, a feed port 14 is installed on one side of the outer wall of the top cover 2, a bottom cover 15 is installed at the bottom of the outer wall of the body 1, and a bin door 16 is installed at the bottom of the bottom cover 15. If the user needs to take out the dried plastic particles, he only needs to open the bin door 16. After the bin door 16 is opened, the plastic particles will fall into the inner wall of the storage box 20.
[0025] In this embodiment, circulation pipes 17 are connected to both sides of the outer wall of the body 1, a booster pump 18 is installed on one side of the outer wall of the body 1, a base frame 19 is installed at the bottom of the booster pump 18, a storage box 20 is installed on the inner wall of the base frame 19, and heating plates 21 are installed on both sides of the inner wall of the body 1. After the booster pump 18 is started, the booster pump 18 will suck the hot air from the inner wall of the body 1 through the circulation pipe 17 on one side of the outer wall of the body 1, and then discharge it into the interior of the body 1 through the circulation pipe 17 on the other side of the outer wall of the body 1, thereby realizing heat circulation.
[0026] In this embodiment, a cavity is provided on the inner wall of the mounting block 6, and the power rod 5 passes through the cavity of the mounting block 6. When the motor 4 is started, the power rod 5 is driven to rotate.
[0027] In this embodiment, the teeth of the power wheel 9 are meshed with the teeth of the linkage wheel 10, and the power wheel 9 and the linkage wheel 10 form a meshing transmission connection structure. When the rotating rod 8 rotates, it will drive the power wheel 9 to rotate, and when the power wheel 9 rotates, it will drive the linkage wheels 10 on both sides to rotate synchronously.
[0028] In this embodiment, both ends of the circulation pipe 17 are connected to the inner wall of the body 1, the outer wall of the circulation pipe 17 is connected to the output end of the booster pump 18, one end of the circulation pipe 17 on one side of the body 1 is installed at the output end of the booster pump 18, and the outer wall of the circulation pipe 17 on the other side of the body 1 is connected to the second output end of the booster pump 18.
[0029] In this embodiment, the inner wall of the rotating block 7 is connected to the power rod 5 through a rotating shaft, and the rotating block 7 and the power rod 5 form a transmission connection structure. When the rotating block 7 rotates, it will rotate on the outer wall of the power rod 5, thereby preventing too many plastic particles from accumulating on the top of the rotating block 7.
[0030] The working principle of this utility is:
[0031] First, when using the utility model, it is necessary to start the motor 4 and the booster pump 18. After the motor 4 is started, the power rod 5 will be driven to rotate, and the power rod 5 will drive the mounting block 6 to rotate. In daily use, the user can judge whether the power rod 5 is rotating normally by observing whether the mounting block 6 is rotating. When the power rod 5 rotates, the rotating block 7 will be driven to rotate. At the same time, since the rotating rod 8 and the power rod 5 are connected by a rotating shaft, the power rod 5 will drive the rotating rod 8 to rotate when it rotates, so that the rotating rod 8 drives the power wheel 9 to rotate. When the power wheel 9 rotates, the linkage wheel 10 will be driven to rotate. When the linkage wheel 10 rotates, the linkage rod 11 will be driven to rotate. The linkage rod 11 will drive the auxiliary stirring rod 12 to rotate, and the rotating rod 8 will also drive the main stirring rod 13 to rotate when it rotates. At this time, the user pours the plastic particles into the body 1 from the feeding port 14, and then the auxiliary stirring rod 12 and the main stirring rod 13 will stir the plastic particles inside the body 1. At the same time, since a heating plate 21 is installed on the inner wall of the body 1, the heating plate 21 will increase the internal temperature of the body 1. In addition, the stirring of the auxiliary stirring rod 12 and the main stirring rod 13 will make the plastic particles fully dried and dehydrated inside the body 1. At this time, some hot steam will accumulate inside the body 1. In order to ensure the normal operation of the body 1 and to circulate the heat energy, the booster pump 18 will inhale the hot steam inside the body 1 through the circulation pipe 17. The hot steam will move inside the circulation pipe 17 and cool down when the hot steam moves. After that, the booster pump 18 will discharge the gas back into the body 1 through the circulation pipe 17, and then heat it through the heating plate 21, thereby reciprocating to realize heat recovery and circulation. After the plastic particles are dried, they will be accumulated at the bottom cover 15. At this time, the user only needs to open the warehouse door 16 to allow the plastic particles to fall into the storage box 20 for collection. At this point, the practical work is completed.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
