Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a plastic drying device, especially a plastic drying device capable of improving heating efficiency to reduce the use cost and reducing the manufacturing cost. * [Prior art] As shown in FIG. 3, it is a conventional plastic drying device, which has a heating tank 8 1 and a drying tank 8 2. The drying tank 8 2 is used for placing plastic to be dried. The heating tank 8 1 is provided with a blast fan 8 3 at the top, so as to draw outside air into the heating tank 8 1, and a heater 8 4 is placed in the heating tank 8 1 so that the heater 8 4 A flow channel 8 5 for air circulation is formed around, and an air duct 8 _ 6 俾 is provided at the bottom of the heating tank 8 1 to communicate the flow channel 8 5 and the drying tank 8 2 in the heating tank 8 1: However, the foregoing The plastic drying structure of the structure, the long output of the flow channel 8 5 is only about the same as the height of the heating tank 8 1, that is, the cold air introduced by the blower 8 ^ must flow from the blower 8 3 to the supply air. During the period of the tube 86 is heated to the required temperature, plus the length of the flow channel 85 is limited, the power of the heater 8 4 needs to be relatively increased, so that the cold air drawn by the fan 8 3 can be cooled. It is heated to the required temperature in a short time, which will lead to increased power consumption and significantly increase the cost of use. In addition, the periphery of the runner 8 5 is the peripheral wall of the heating tank 81. After use for a period of time, the temperature of the peripheral wall of the heating tank 81 will increase, which may cause burns to the operator. 1 An additional layer of heat insulation material 8 7 is provided on the outer edge to avoid the heating tank 8 1 The temperature of the outer edge is too high and the operator may be burned, but the addition of heat insulation material 8 7 will increase the manufacturing cost.

Creative Instructions (2) High. Based on this [new internal capacity creation] The main drying device body 'makes the way' and can re-flow into the function of internal efficiency. The next hot air does not need to be provided with a plastic cover and an outflow to be preheated. It is a problem outside the wall to provide two heating elements. 'The aforementioned plastic drying device actually needs to be improved. The purpose is to solve the above-mentioned problems and provide a method. Since the space inside the heat tank of the heater outer cover provided in the heating tank is divided by the cover body into an inner flow channel for the fan to be blown. The drawn-in cold air flows through the outer flow path and the flow path is heated to the required temperature to achieve the effect. The purpose is the external flow channel near the peripheral wall of the heating tank. Its working temperature is relatively low. Therefore, placing a heat insulation material in the heating tank can avoid burns. To achieve the above purpose, a plastic drying device created by the operator. It has a heating tank and a drying tank. The drying tank is used to store the plastic to be dried. The top of the heating tank is provided with a blower to suck outside air into the heating tank, and the heating tank is provided with There is a heater, and the outer cover of the heater is provided with a cover body, the cover body has an opening facing toward the front, so that the space inside the heating tank is distinguished by the cover body into an inner flow channel and an outer flow channel, and the cover body is away from An air pipe 俾 is provided at one end of the opening to send air to the drying tank. The above and other objects and advantages of Rubin's creation are not difficult to obtain from the detailed description and accompanying drawings of the selected embodiments below. Of course, this creation allows some differences in some other pieces ’or the arrangement of the other pieces, but the chosen embodiment is detailed in this specification-

Creation Instructions (3) Description, and its structure is shown in the drawings. [Embodiment] Please refer to Fig. 1 and Fig. 2. The structure shown in the figure is the structure of the embodiment selected for the creation. This is for illustration only. It is not limited by this structure in patent applications. The plastic drying device of this embodiment has a heating tank 1 and a drying tank 2 which are used for placing the plastic to be dried. A heating fan 1 1 is provided on the top of the heating tank 1 so as to protect the outside world. Air is drawn into the heating tank 1, and a heater 12 is provided in the heating tank 1. The heater 1 2 is provided with a cover 1 3, and the cover 13 has a downward opening 1 1 so that The space inside the heating tank 1 is divided into an inner flow channel 14 and an outer flow channel 15 by the cover body 1 3, and an air supply pipe 16 is provided at one end of the cover body 13 away from the opening 1 3 1. Air is sent to the drying tank 2. Please refer to FIG. 2, because the heater 12 is provided with a cover body 1 3, the space inside the heating tank 1 is divided into an inner flow channel 14 and an outer flow channel 1 5, and the heat energy generated by the heater 12 may be caused by The heat radiation indirectly heats the cover body 1 3, so that the cold air drawn in by the blower fan 11 is preheated by the warm cover body when passing through the outer flow path 15, and the preheated air is provided by the cover. The opening 1 3 1 at the bottom of the body 1 3 flows upward into the inner flow channel 1 4, and the preheated air is directly heated by the heater 12 in the inner flow channel 14 to reach the required working temperature. Finally, Then, the air is sent to the drying tank 2 by the air supply pipe 16 to dry the plastic. Since the thermal energy of the heater 12 is used to indirectly preheat the air and directly heat the preheated air, the utilization of heat can be greatly improved.

Creative Instructions (4) 5 In this way, the workers who are hot enough to be near the Gao 1 5 ’and their work place heat insulation materials, manufacturing costs. In summary, low use cost and high efficiency. The above restrictions on this creation are within the scope of this creation, and it is indeed possible to apply for a fan. Only the heater 12 with a lower power can add air to the temperature, so as to save electricity and reduce the use cost. Then, the part of the peripheral wall of ί is for the preheated air outside the flow path = again, so low. Therefore, the outer edge of the peripheral wall of the heating tank 1 does not need to be set to avoid burns. Reduce the structure design of this creation, which can save electricity and reduce the cost of manufacturing without the need to add heat insulation materials. The disclosure of the two-way embodiment is used to explain this creation, and is not intended to pretend that any numerical change or equivalent The replacement of components should still be explained in detail. 〇 ~ Detailed description will enable those skilled in the art to understand the purpose, and it has actually complied with the provisions of the Patent Law.
