Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a drying device for PET transparent bottles. Background Technology

[0002] Polyethylene terephthalate (PET), with the chemical formula (C10H8O4)n, is produced by transesterification of dimethyl terephthalate with ethylene glycol or by esterification of terephthalic acid with ethylene glycol to synthesize diethyl terephthalate, followed by polycondensation. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth, glossy surface. It is a common resin in daily life and can be classified into APET, RPET, and PETG. It exhibits excellent physical and mechanical properties over a wide temperature range, with a service temperature up to 120℃. It has excellent electrical insulation properties, even at high temperatures and high frequencies, but its corona resistance is relatively poor. It also has good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability.

[0003] As the name suggests, PET transparent bottles are transparent bottles made of PET material. After production, PET transparent bottles need to be rinsed and then dried, which requires the use of drying equipment.

[0004] However, existing drying equipment for PET transparent bottles has the following problem: due to the large temperature difference between the inside and outside of the existing drying equipment, the water vapor carried out by the PET transparent bottles after drying will liquefy and adhere to the PET transparent bottles when it encounters the low temperature environment outside the drying equipment, thus affecting the drying effect. Therefore, a drying equipment for PET transparent bottles is proposed. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] like Figure 1-2 As shown, this utility model embodiment provides a drying device for PET transparent bottles, including a device shell 1, a heating chamber 2, a blower 3, and an auxiliary mechanism 4. The device shell 1 is fixed to the upper end of a support platform 5, and four support legs are fixedly installed in a rectangular array on the lower end face of the support platform 5. Rubber shock-absorbing pads are provided at the lower end of the support legs. The support platform 5 can be stably supported by the four support legs. The rubber shock-absorbing pads can improve the stability of the support legs supporting the support platform 5, thereby improving the stability of the support platform 5 supporting the device shell 1, and further improving the stability of the device shell 1 in drying PET transparent bottles. The heating chamber 2 is fixedly connected to the left end face of the device shell 1, the blower 3 is fixedly installed and connected to the left end of the heating chamber 2, and the auxiliary mechanism 4 is installed on the device shell 1.

[0044] PET transparent bottles can be placed inside the equipment housing 1, and then the blower 3 and heating box 2 can be started to dry the PET transparent bottles inside the equipment housing 1. The water vapor generated during drying and the residual heat of the equipment housing 1 can be recovered and treated through the auxiliary mechanism 4.

[0045] In this embodiment, a placement platform 8 is also included, which is fixedly installed inside the bottom of the device housing 1.

[0046] The PET transparent bottles that need to be dried can be placed on the top of the placement platform 8.

[0047] The equipment housing 1 has a pick-up and drop-out opening at the front end, and a door panel 6 is installed at the pick-up and drop-out opening. Ventilation holes are provided inside the equipment housing 1.

[0048] Open the door panel 6, and you can put the PET transparent bottles that need to be dried into the upper part of the placement table 8 through the loading and unloading port. The air pressure of the equipment shell 1 can be kept stable through the vent.

[0049] It also includes heating wires 7, and multiple heating wires 7 are provided, with multiple heating wires 7 fixed inside the heating box 2.

[0050] By starting the blower 3 and the heating wire 7, the blower 3 can generate airflow. After the airflow passes through the heating wire 7, the heating wire 7 can heat the airflow into hot air. The hot air enters the equipment shell 1 and can dry the PET transparent bottle.

[0051] like Figure 3-4 As shown, the auxiliary mechanism 4 includes a recovery cylinder 401, an exhaust pipe 404, a spiral pipe 405, a recovery pipe 402, and an air pump 403. The recovery cylinder 401 is fixedly installed on the lower end face of the support platform 5 by a mounting bracket 411. The exhaust pipe 404 is fixedly connected to the left end of the recovery cylinder 401. The spiral pipe 405 is located inside the recovery cylinder 401. One end of the spiral pipe 405 is fixedly connected to the right end of the exhaust pipe 404, and the other end of the spiral pipe 405 passes through the right end of the recovery cylinder 401. One end of the recovery pipe 402 is fixedly connected to the other end of the spiral pipe 405, and the other end of the recovery pipe 402 is fixedly connected to the exhaust port 9 opened at the upper end of the equipment housing 1. The air pump 403 is installed on the recovery pipe 402 and is fixed to the upper end of the equipment housing 1.

[0052] After drying is completed, the air pump 403 is started. The air pump 403 can guide the water vapor generated during drying into the recovery pipe 402 through the exhaust port 9, and then into the spiral pipe 405. The water vapor can transfer heat to the heat exchange water 407 through the spiral pipe 405, thereby realizing the recovery and reuse of the heat in the water vapor. The water vapor after heat exchange can be discharged through the air outlet pipe 404.

[0053] The above design not only recovers heat to achieve energy saving, but also prevents the water vapor carried on the PET transparent bottles from liquefying again after they are removed from the equipment shell 1 after drying, thus avoiding affecting the drying effect of the PET transparent bottles.

[0054] The auxiliary mechanism 4 also includes a hot water exchanger 407 and a water exchanger pipe 408. The hot water exchanger 407 is located inside the recovery cylinder 401. The water exchanger pipe 408 is fixedly connected to the lower end of the recovery cylinder 401. A water pump 406 is installed on the water exchanger pipe 408 and is fixed to the lower end of the recovery cylinder 401.

[0055] When it is necessary to replace the heat exchange water, start the water pump 406. The water pump 406 will discharge the heat exchange water 407 through the water replacement pipe 408. After the water replacement is completed, the external pipe can be connected to the water replacement pipe 408, and then the other end of the external pipe can be inserted into the new heat exchange water 407. Then start the water pump 406, and the new heat exchange water 407 will enter the recovery tank 401 through the external pipe and the water replacement pipe 408 in sequence, thereby realizing the replacement of the heat exchange water 407.

[0056] The auxiliary mechanism 4 also includes a water thermometer 409, which is fixedly installed at the rear end of the equipment housing 1, and the detection end of the water thermometer 409 passes through the rear end of the equipment housing 1 and extends into the interior of the equipment housing 1.

[0057] The heat of the hot water exchanger 407 can be detected by the water thermometer 409. When the heat of the hot water exchanger 407 is too high, the hot water exchanger 407 needs to be replaced.

[0058] The auxiliary mechanism 4 also includes a viewing window 410, which is installed at the rear end of the device housing 1.

[0059] The remaining amount in the recovery cylinder 401 can be observed through the viewing window 410, which makes it easier to fill the recovery cylinder 401 with hot water 407.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
