[0002] PBT granules are a type of thermoplastic polyester plastic granules with high heat resistance, mechanical strength and electrical properties. They are widely used in the automotive, electronics, electrical appliances, chemical, machinery and other fields. PBT granules have excellent processing performance and can be used to manufacture various products such as automotive parts, electronic components, electrical appliance housings, etc. through injection molding, extrusion, blow molding and other molding processes. The appearance and performance of PBT granules can be adjusted by adding different modifiers and fillers to meet the needs of different fields.

[0003] In the prior art, after PBT particles are processed, they need to be dried in time because they contain a large amount of volatile organic matter and moisture.

[0008] Preferably, the guide plate is rotatably connected to the drying box; a support frame is fixedly connected to the inside of the drying box; the support frame is arranged below the end of the guide plate; an elastic plate is connected between the support frame and the guide plate; this step, by providing the support frame and the elastic plate, can make the guide plate shake up and down when the PBT particles move along the guide plate, thereby lifting the PBT particles moving along the guide plate, further improving the contact effect between the surface of the PBT particles and the hot air, and further improving the drying effect of the PBT particles.

[0009] Preferably, an air guide hole is opened in the middle of the guide plate; the air guide hole is set to be small at the top and large at the bottom; there are multiple air guide holes and they are evenly distributed in the middle of the guide plate; this step allows hot air to pass through the guide plate by providing the air guide holes, thereby making the movement of hot air inside the conveyor belt more uniform, making the temperature inside the drying box more uniform and stable, further improving the contact effect between the surface of the PBT particles and the hot air, and further improving the drying effect of the PBT particles.

[0010] Preferably, an elastic curtain is fixedly connected to the bottom of the drying box; the elastic curtains are multiple and symmetrically arranged on both sides of the bottom of the drying box; this step can block the temperature exchange between the inside of the drying box and the outside air by providing the elastic curtain, thereby making the temperature inside the conveyor belt more stable.

[0011] Preferably, the side wall of the drying box is provided with an observation window; the observation window is made of transparent material; this step, by providing an observation window, allows the staff to more conveniently observe the drying conditions of the PBT particles inside the drying box, thereby facilitating the staff to add materials to the inside of the drying box, thereby improving the staff's work efficiency.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figures 1 to 4 As shown, a PBT particle production drying equipment described in an embodiment of the utility model comprises a conveyor belt 1; a drying box 11 is fixedly connected to the top of the conveyor belt 1; a feed chute 12 is fixedly connected to the top of the drying box 11; a guide plate 13 is arranged inside the drying box 11; the guide plates 13 are multiple and cross-arranged inside the drying box 11; a drying component is installed on the guide plate 13; when working, the staff guides the PBT particles to be dried from the feed chute 12 into the drying box 11, and the PBT particles will move along the guide plate 13, and the heating component will heat the inside of the conveyor belt 1, thereby heating the conveyor belt 1. The PBT particles moving inside the conveyor belt 1 are dried, and then fall to the middle of the conveyor belt 1 and are transported by the conveyor belt 1. In this step, the PBT particles can be heated and dried by providing a drying box 11, a guide plate 13 and a heating component. Since there are multiple guide plates 13 and they are cross-arranged, the travel of the PBT particles inside the conveyor belt 1 can be extended, thereby extending the contact time between the PBT particles and the hot air, and improving the drying effect of the hot air on the PBT particles. Since the PBT particles roll along the surface of the guide plate 13, the surface of the PBT particles can be made to contact the hot air more evenly, thereby improving the drying effect of the PBT particles.

[0025] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the drying assembly includes a hot air blower 2; the hot air blower 2 is installed on the side wall of the drying box 11; the air outlet end of the hot air blower 2 is connected to an air guide duct 21; the air guide duct 21 is fixedly connected to the inside of the drying box 11; the air guide duct 21 is arranged at the bottom of the guide plate 13; a vent 22 is opened on the top of the air guide duct 21; the vent 22 is multiple and evenly distributed on the top of the air guide duct 21; when working, when the PBT particles move along the guide plate 13, the staff starts the hot air blower 2, and this At the same time, the hot air blower 2 heats the air, fills it into the air duct 21, and discharges it outward from the vent 22. In this step, the hot air blower 2, the air duct 21 and the vent 22 are provided, so that the PBT particles moving along the guide plate 13 can be heated and dried. Because there are multiple vents 22 evenly distributed on the top of the air duct 21, the temperature inside the conveyor belt 1 can be made more uniform, so that the surface of the PBT particles can be more evenly contacted with the hot air, and the drying effect of the PBT particles is further improved.

[0026] Further, such as Figure 2 and Figure 4As shown, the guide plate 13 is rotatably connected to the drying box 11; a support frame 3 is fixedly connected to the inside of the drying box 11; the support frame 3 is arranged below the end of the guide plate 13; an elastic plate 31 is connected between the support frame 3 and the guide plate 13; during operation, when the PBT particles move along the guide plate 13, the gravity of the PBT particles themselves will squeeze the guide plate 13 downward, and at this time the elastic plate 31 will push the guide plate 13 upward, thereby causing the guide plate 13 to shake up and down. This step is provided with the support frame 3 and the elastic plate 31, so that when the PBT particles move along the guide plate 13, the guide plate 13 can be shaken up and down, thereby lifting the PBT particles moving along the guide plate 13, further improving the contact effect between the surface of the PBT particles and the hot air, and further improving the drying effect of the PBT particles.

[0027] Further, such as Figure 2 and Figure 4 As shown, an air guide hole 4 is opened in the middle of the guide plate 13; the air guide hole 4 is set to be small at the top and large at the bottom; there are multiple air guide holes 4 and they are evenly distributed in the middle of the guide plate 13; in this step, by providing the air guide holes 4, hot air can pass through the guide plate 13, thereby making the movement of hot air inside the conveyor belt 1 more uniform, making the temperature inside the drying box 11 more uniform and stable, further improving the contact effect between the surface of the PBT particles and the hot air, and further improving the drying effect of the PBT particles.

[0028] Further, such as Figures 1 to 4 As shown, an elastic curtain 5 is fixedly connected to the bottom of the drying box 11; the elastic curtain 5 is multiple and symmetrically arranged on both sides of the bottom of the drying box 11; this step, by providing the elastic curtain 5, can block the temperature exchange between the inside of the drying box 11 and the outside air, thereby making the temperature inside the conveyor belt 1 more stable.

[0029] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the side wall of the drying box 11 is provided with an observation window 6; the observation window 6 is made of transparent material; this step allows the staff to more conveniently observe the drying condition of the PBT particles inside the drying box 11 by providing the observation window 6, thereby facilitating the staff to add materials to the drying box 11, thereby improving the work efficiency of the staff.

[0030] Working principle: During operation, the staff will introduce the PBT particles to be dried from the feed trough 12 into the drying box 11. At this time, the PBT particles will move along the guide plate 13. At this time, the heating component will heat the inside of the conveyor belt 1, and then dry the PBT particles moving inside the conveyor belt 1, and then fall to the middle of the conveyor belt 1 and be transported by the conveyor belt 1. When the PBT particles move along the guide plate 13, the staff will start the hot air blower 2. At this time, the hot air blower 2 will heat the air, and then fill it into the air guide duct 21, and discharge it from the vent 22. When the PBT particles move along the guide plate 13, the gravity of the PBT particles themselves will squeeze the guide plate 13 downward. At this time, the elastic plate 31 will push the guide plate 13 upward, and then make the guide plate 13 shake up and down.
