Detailed Embodiments
[0017] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
[0018] Embodiment: Please refer to Figure 1 - Figure 6 , the present utility model provides a technical solution: a corrosion-resistant drying oven, comprising: a protective shell 1; a rotating door 2, the outer wall of the rotating door 2 is rotatably connected to the inner wall of the protective shell 1; a blower 3, the bottom of the blower 3 is fixedly connected to the inner wall of the protective shell 1; a positioning plate 4, the inner wall of the positioning plate 4 is fixedly connected to the outer wall of the output end of the blower 3; a heating plate 5, the outer wall of the heating plate 5 is fixedly connected to the inner side wall of the protective shell 1; the protective shell 1 includes a connecting shell 11, a ventilation opening 12 is formed in the wall of the connecting shell 11, an air intake groove 13 is formed in the inner wall of the middle part of the connecting shell 11, an air guide duct 14 is formed in the inner wall of the connecting shell 11 away from the ventilation opening 12, a placement box 15 is fixedly connected to the inner wall of the connecting shell 11, the bottom of the blower 3 and the side wall of the positioning plate 4 are both fixedly connected to the inner wall of the connecting shell 11, and the inner wall of the connecting shell 11 is fixedly connected to the outer wall of the heating plate 5. When in use, the rotating door 2 is pulled open, and the tray and the object to be dried on the tray are placed on the positioning frame 154 of the connecting box 151, the rotating door 2 is closed, the blower 3 and the heating plate 5 in the protective shell 1 are started, the input end of the blower 3 inhales air through the ventilation opening 12, the inhaled air is blown out through the inside of the blower 3, and the output end of the blower 3 is positioned by the positioning plate 4, so that the air flow passes through the heated heating plate 5. The heating plate 5 heats its own heating wire, so that the air blown towards the heating plate 5 is heated by the heating wire. When the air passes through the grid-shaped heating plate 5 composed of heating wires, it is heated, and at this time, the heated air enters the air guide duct 14 through the air intake groove 13.
[0019] The placement box 15 includes a connection box 151. The outer wall of the connection box 151 is fixedly connected with a ventilation plate 152. The inner wall of the ventilation plate 152 is rotatably connected with a fan blade 153. The side wall inside the connection box 151 is fixedly connected with a positioning frame 154. The inner walls on both sides of the connection box 151 are fixedly connected with lateral ventilation plates 155. The inner wall of the connection box 151 is symmetrically and fixedly connected with a guiding device 156. The outer wall of the ventilation plate 152 is fixedly connected with the inner wall of the connection shell 11. The inner wall of the connection shell 11 is fixedly connected with the side wall of the connection box 151 on the side away from the ventilation plate 152. Due to the sloping setting of the air inlet groove 13, the hot air moves towards the upper and lower ends of the air guide duct 14, making it difficult for the hot air to directly pass through the lateral ventilation plate 155 near one end of the fan 3. The hot air passes through the guiding device 156. Due to the shape setting of the guiding shell 1562 on the guiding device 156, it is difficult for the hot air to directly enter the position of the communication port 1563 when passing through. Only a small amount of hot air passes through the ventilation slots 1564 of the fixing plate 1561 due to factors such as backflow. Therefore, most of the hot air continues to move and moves towards the lateral ventilation plate 155 away from the fan 3. At this time, the hot air will fill the inside of the air guide duct 14. When the fan 3 further increases the air extraction volume and exhaust volume at this time, the hot air will search for other inlets, so that the upper, lower, left, and right positions of the placement box 15 intake air simultaneously. At this time, the winds in the four directions cancel each other out.
[0020] The guiding device 156 includes a fixing plate 1561. A ventilation slot 1564 is formed in the wall of the fixing plate 1561. The top of the fixing plate 1561 is fixedly connected with a guiding shell 1562. A communication port 1563 is formed in the wall of the guiding shell 1562. The side wall of the fixing plate 1561 is fixedly connected with the inner wall of the connection box 151. The shape of the inside of the connection box 151 is set to be smooth. The external shape of the connection box 151 is a cube, while the internal shape is polygonal. Excluding the straight surface shapes on the four sides, the corner positions are smooth arc surface shapes. The advantage of such a setting is to avoid sharp corners remaining inside the connection box 151. At the same time, as the storage position for drying items, the connection box 151 is not provided with narrow channels. Since stress concentration is likely to occur in channels and corners and it is difficult to clean, it will accelerate the corrosion speed inside the connection box 151, and further make it not easy to corrode inside the connection box 151.
[0021] Working principle:
[0022] When in use, the air at the drying position inside the drying box circulates, so that the connection box 151 is heated evenly and the air intake is stable. When in use, the rotating door 2 is opened to put the tray and the object to be dried on the tray into the positioning frame 154 of the connection box 151, the rotating door 2 is closed, and the fan 3 and the heating plate 5 in the protective shell 1 are started. The input end of the fan 3 inhales air through the vent 12, and the inhaled gas is blown out through the inside of the fan 3. The output end of the fan 3 is positioned by the positioning plate 4, so that the airflow passes through the heated The heating plate 5 heats its own electric heating wire, so that the air blowing toward the heating plate 5 is heated by the electric heating wire. When the air passes through the grid-shaped heating plate 5 composed of the electric heating wire, it is heated. At this time, the heated air passes through the air inlet groove 13 and enters the air guide 14. Due to the slope setting of the air inlet groove 13, the hot air moves toward the upper and lower ends of the air guide 14, making it difficult for the hot air to directly pass through the side vent plate 155 near one end of the fan 3. The hot air passes through the guide device 156. Due to the guide on the guide device 156, the hot air The shape of the shell 1562 makes it difficult for the hot air to directly enter the connecting port 1563 when passing through. Only a small amount of hot air passes through the ventilation slot 1564 of the fixed plate 1561 due to factors such as backflow, so most of the hot air continues to move and moves to the side ventilation plate 155 away from the fan 3. At this time, the hot air will fill the interior of the air guide 14. At this time, when the fan 3 further increases the suction and exhaust volumes, the hot air will find other entrances, so that the upper, lower, left and right positions of the placement box 15 are simultaneously intake, and the wind forces in the four directions offset each other at this time, so that the debris on the surface of the object to be dried is difficult to be blown off, and the objects in the placement box 15 are heated evenly and finally discharged through the ventilation plate 152 and the fan blades 153. The fan blades 153 guide the airflow to prevent the directly blown airflow from scalding the personnel passing by the back of the drying box, and at the same time make the interior of the placement box 15 evenly heated and blown, so that impurities are difficult to fall and accumulate, thereby improving the corrosion resistance of the interior of the drying box and maintaining long-term stability.
[0023] The interior of the connection box 151 is arranged to be smooth. The exterior shape of the connection box 151 is a cube, while the interior shape is a polygon. Except for the straight surfaces of the four sides, the corners are smooth arc surfaces. The advantage of such arrangement is that sharp corners are avoided inside the connection box 151. At the same time, the connection box 151 is used as a storage location for dry items, and no narrow passages are arranged. Since passages and corners are prone to stress concentration and are difficult to clean, the corrosion rate of the interior of the connection box 151 will be accelerated, and the interior of the connection box 151 will be further less prone to corrosion. At the same time, right angles and corners are avoided as much as possible inside the connection box 151 during design, so that the staff can conduct a more complete cleaning of the interior of the connection box 151, making it easier to keep the interior of the connection box 151 clean.
