[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a plastic particle dryer, including a bottom plate 1, on the top of the bottom plate 1 there is an installation box 11, inside the installation box 11 there are a plurality of heating rods 10 installed at equal intervals, on the top of the installation box 11 there is a fixed connection with a hollow box 8, on the inner bottom wall of the hollow box 8 there are a plurality of heat dissipation columns 9 communicated at equal intervals, on the top rear side of the bottom plate 1 there is a fixed connection with an industrial air pump 16, the input end of the industrial air pump 16 is communicated with a placement box 12, the inner wall of the placement box 12 is installed with a filler 20, on the right side of the placement box 12 there is a communication with an air inlet pipe 15, the end of the air inlet pipe 15 is communicated at the top of the hollow box 8, the output end of the industrial air pump 16 is communicated with an exhaust pipe 17, the end of the exhaust pipe 17 is communicated at the bottom of the installation box 11, on the top right side of the bottom plate 1 there is an installation of a blanking mechanism 2; on the top right end of the bottom plate 1 there is an installation of a storage box 4, the filler 20 is made of activated carbon filler 20;

[0039] Specifically, when the heating rod 10 is started, it will generate heat, causing the air inside the installation box 11 to quickly heat up and turn into hot air; due to the natural upward floating characteristic of hot air, it will be dissipated into the hollow box 8 through the holes on the heat dissipation column 9; the design of these holes has been carefully calculated to ensure that the size is smaller than the size of the plastic particles, thus effectively preventing the plastic particles from falling; next, the plastic particles to be dried are poured into the hollow box 8; when the hot air contacts the plastic particles, the particles will bounce due to heat and collide with the heat dissipation column 9; this bouncing and collision not only makes the plastic particles evenly heated, but also promotes the heat exchange between the hot air and the particles, thus accelerating the drying process; at the same time, the industrial air pump 16 starts to work, introducing external air into the system through the air inlet pipe 15; after these newly introduced hot air enters the placement box 12, it will be processed by the activated carbon filler 20; the strong adsorption ability of activated carbon can effectively remove the water vapor and impurities in the hot air, ensuring the air quality during the drying process; the clean hot air after being processed by the activated carbon then returns to the installation box 11 through the exhaust pipe 17 and continues to float upward together with the newly generated heat; this design enables the recycling of heat energy, not only improving the energy utilization efficiency, but also greatly reducing the production cost and energy waste.

[0040] Refer to Figure 1 and Figure 4, the blanking mechanism 2 includes a vertical frame 202. The bottom of the vertical frame 202 is fixedly connected to the top rear side of the bottom plate 1. The upper middle part of the rear side of the vertical frame 202 is fixedly connected with an electric push rod two 201. The output end of the electric push rod two 201 penetrates through the vertical frame 202 and is fixedly connected with a storage box 204. The lower middle part of the rear side of the storage box 204 is fixedly connected with a fixing frame 205. The inner side of the fixing frame 205 is fixedly connected with a fixing rod 203. Torsion springs 208 are arranged at both the left and right ends of the outer wall of the fixing rod 203. The far ends of the torsion springs 208 are respectively fixedly connected to the left and right sides of the inner wall of the fixing frame 205. The middle part of the fixing rod 203 is rotatably connected with a rotating plate 209. The adjacent ends of the torsion springs 208 are respectively fixedly connected to the middle parts of the left and right sides of the rotating plate 209. The right side of the vertical frame 202 is fixedly connected with an arc-shaped rod 207. A plurality of fixing strips 206 are fixedly connected to the top of the arc-shaped rod 207 at equal intervals; The top of the hollow box 8 is fixedly connected with an electric push rod one 6. The output end of the electric push rod one 6 is fixedly connected with a baffle 7;

[0041] Specifically, when the plastic particles gradually accumulate at the bottom of the hollow box 8 to form a certain amount, the electric push rod one 6 is activated to drive the baffle 7 to move up and down; This action is precise and rapid. The rising of the baffle 7 just opens the opening of the hollow box 8 properly, enabling the plastic particles to fall smoothly into the storage box 4 for storage; As the plastic particles continue to fall into the storage box 4, when the preset storage amount is reached, the baffle 7 is activated again and slowly descends to tightly close the hollow box 8; At the same time, the bagged desiccant on the other side is accurately put into the storage box 204; At this time, the electric push rod two 201 starts to work. It drives the storage box 204 to move smoothly and powerfully; During this process, the rotating plate 209 collides with the fixing strip 206 skillfully; This collision is not a simple contact, but a carefully designed mechanical interaction; When the rotating plate 209 contacts the fixing strip 206, the torsion spring 208 starts to be stressed, driving the rotating plate 209 to deform and turn; This turning action just opens the bottom position of the storage box 204, enabling the desiccant to fall accurately into the storage box 4; And when the rotating plate 209 passes by the fixing strip 206, the torsion spring 208 immediately rebounds elastically, driving the rotating plate 209 to quickly reset and tightly seal the opening of the storage box 204; This series of actions ensures the uniform input of the desiccant. It is worth mentioning the equal interval setting of the fixing strips 206; This design enables the electric push rod two 201 to ensure the uniform laying of the desiccant in the storage box 4 during the pushing process; This laying method of one layer of desiccant and one layer of plastic particles not only improves the storage efficiency, but also increases the drying degree of the plastic particle storage, effectively preventing the influence of moisture on the quality of the plastic particles.

[0042] Refer to Figure 1 、 Figure 3 and Figure 4, at the lower middle part of the rear side of the vertical frame 202, an electric push rod three 18 is fixedly connected, and the output end of the electric push rod three 18 penetrates through the vertical frame 202 and is fixedly connected with a push plate 19; a plurality of legs 5 are fixedly connected to the bottom wall of the installation box 11 at equal intervals; a control box 3 is installed in the middle of the top end of the bottom plate 1; a hinge 14 is rotatably connected to the top of the placement box 12, and a rotating plate 13 is fixedly connected to the front side of the hinge 14;

[0043] Specifically, the control box 3 is used to drive the push plate 19 to move, so as to push out the storage box 4, which is convenient for packing and sealing. The control box 3 is used to control the opening and closing of the equipment. The rotation of the rotating plate 13 is used to open or close the placement box 12 for replacing the filler 20.

[0044] Working principle: Turn on the heating rod 10 to generate heat, so that the air in the installation box 11 is converted into hot air. The hot air naturally floats upward and is emitted into the hollow box 8 through the holes on the heat dissipation column 9. The size of the holes on the heat dissipation column 9 can be designed according to the size of the plastic particles to avoid the dropping of plastic particles. Pour the plastic particles into the hollow box 8. The plastic particles collide with the heat dissipation column 9 and thus bounce. The hot air is used to dry the plastic particles. At the same time, turn on the industrial air pump 16 to drive the intake pipe 15 to intake air. The hot air enters the placement box 12. The activated carbon filler 20 adsorbs the water vapor and impurities in the hot air. After the adsorption is completed, the hot air is discharged into the installation box 11 through the exhaust pipe 17 and continuously floats upward with the newly generated heat, and the thermal energy recycling process can be carried out, avoiding energy waste. And when a certain amount of plastic particles accumulates at the bottom of the hollow box 8, turn on the electric push rod one 6 to drive the baffle 7 to move up and down. The baffle 7 rises to open the opening of the hollow box 8, so that the plastic particles fall into the storage box 4 for storage. After storing a certain amount, the baffle 7 descends to close the hollow box 8. At the same time, put the bagged desiccant into the storage box 204, turn on the electric push rod two 201 to drive the storage box 204 to move. During the movement of the storage box 204, the rotating plate 209 collides with the fixed strip 206, so that the torsion spring 208 is stressed and drives the rotating plate 209 to deform and turn over, so as to open the bottom position of the storage box 204 and make the desiccant fall into the storage box 4. After the rotating plate 209 passes by the fixed strip 206, the torsion spring 208 synchronously rebounds elastically, driving the rotating plate 209 to reset to close the opening of the storage box 204. The fixed strips 206 are arranged at equal intervals. Through the push of the electric push rod two 201, the desiccant can be evenly put into the storage box 4. At this time, a certain number of plastic particles accumulate and can be discharged. The laying method of one layer of desiccant and one layer of plastic particles can be adopted, which increases the drying degree of the plastic particle storage and brings convenience to subsequent use.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
