[0023] like Figure 1-5 As shown: This embodiment provides a hot air circulation drying box 100, including a drying box 100, the four corners of the bottom of the drying box 100 are fixedly connected to pillars, the middle of the drying box 100 is fixedly connected to a bracket 101, the middle of the bracket 101 is rotatably connected to a turntable 102, the top of the turntable 102 is provided with a plurality of anti-sliding blocks, the bottom of the drying box 100 is provided with a mounting groove, the bottom of the mounting groove is fixedly connected to a heat dissipation fan 107, the bottom of the heat dissipation fan 107 is fixedly connected to a protective cover, the top inner wall of the mounting groove is fixedly connected to a rotating motor 114, the output shaft of the rotating motor 114 is fixedly connected to the middle of the turntable 102, one side of the drying box 100 is connected to a cover plate 115 through a hinge, and one side of the cover plate 115 is fixedly connected to a pull rod;
[0024] The support column can support the drying box 100 so that it can be placed firmly on the ground or on a workbench. The bracket 101 supports and fixes the turntable 102. The turntable 102 can be rotated synchronously by controlling the operation of the rotating motor 114. The bracket 101 ensures that the turntable 102 can rotate smoothly. The anti-slip block on the turntable 102 can effectively prevent the material from sliding or falling during the drying process, ensuring the drying effect while also improving the safety of operation. The cover 115 makes the opening and closing of the box convenient and flexible. When it is necessary to add materials or check the drying situation, the operator can easily open the cover 115 to complete the corresponding work. At the same time, the pull rod design improves the convenience of operation. The heat dissipation fan 107 can quickly cool the air at the bottom, with hot air rising and cold air falling, which is convenient for the rapid discharge of cold air in subsequent processes. The protective cover protects the heat dissipation fan 107 to prevent it from being hit or damaged by external objects during use.
[0025] Drying tube 103 Figure 1 , 3 As shown,
[0026] The top of the drying box 100 is rotatably connected to four drying tubes 103 arranged in an array, the middle of each drying tube 103 is fixedly connected to an electric heating tube 116, one side of the drying tube 103 is rotatably connected to the same connecting tube 104, a circulation fan 105 is fixedly connected to the bottom of one side of the drying box 100, the other side of the circulation fan 105 is fixedly connected to a circulation tube 106, the circulation tube 106 is connected to the connecting tube 104, the center of the circulation tube 106 is connected in series with a condenser 108, the middle of the circulation tube 106 is connected in series with an exhaust fan 109, the wind direction of the exhaust fan 109 is upward, and the exhaust fan 109 is located on the upper side of the condenser 108;
[0027] When the material is placed, the electric heating tube 116 can be controlled to generate heat, so that the temperature inside the drying tube 103 increases, thereby achieving the drying process of the material. At the same time, the connecting tube 104 connects multiple drying tubes 103 together to form an integral channel, so that heat can be transferred and distributed between the drying tubes 103, thereby improving the utilization rate of heat and the drying effect. In this process, hot air rises and cold air falls, and the circulating fan 105 can discharge the moisture and low-temperature air generated during the drying process out of the bottom of the drying box 100, accelerating the air circulation. The air enters the circulating tube 106 and passes through the The cooling treatment of the condenser 108 condenses and discharges the moisture, and the treated drier air returns to the connecting pipe 104 through the circulation pipe 106 again, and enters the drying pipe 103 for recycling, which can keep the air in the drying box 100 dry and circulative, and prevent the outside air from entering the drying box 100 to cause humidity increase or air pollution. At the same time, the exhaust fan 109 has an upward wind direction, and can evenly disperse the drier air treated by the condenser 108 into the drying pipe 103 through the connecting pipe 104, and then be heated by the electric heating pipe 116 in the drying pipe 103, so that the material is dried.
[0028] Sprocket 110 Figure 1 As shown,
[0029] A sprocket 110 is fixedly connected to the middle of one end of the drying tube 103, two sprockets 110 form a group, and the two groups of sprockets 110 are symmetrically arranged. The two sprockets 110 in each group of sprockets 110 are connected by a chain 111. Two supports 112 are fixedly connected to one side of the drying box 100, and a guide motor 113 is fixedly connected to the middle of one side of the support 112. The output shaft of the guide motor 113 is fixedly connected to the middle of the sprocket 110 of the adjacent group of sprockets 110. A plurality of exhaust ports arranged in an array are opened at the bottom of the drying tube 103, and a guide head is fixedly connected to the middle of the exhaust port;
[0030] By controlling the operation of the guide motor 113, the sprocket 110 can be driven to rotate, and then all the drying tubes 103 can be rotated through the transmission effect of the chain 111, driving the position of the guide head to change, thereby achieving uniform drying of different positions of the material, improving the drying effect and efficiency, and the guide head can guide the dry air to flow to different parts of the drying box 100, so that the heat is more evenly distributed on the surface of the material, avoiding local overheating or uneven drying, and cooperating with the rotating turntable 102 to further improve the uniformity and efficiency of material drying. At the same time, the design of the exhaust port allows the moisture generated during the drying process to be discharged smoothly, avoiding moisture accumulation in the drying box 100 and affecting the drying effect. The coordinated use of the guide motor 113, the sprocket 110 and the chain 111 makes the rotation of the drying tube 103 more stable and reliable, and improves the stability and service life of the equipment.
[0031] Working principle:
[0032] The operator places the material to be dried on the turntable 102, which is located inside the drying box 100 and supported by the pillars and the bracket 101. The turntable 102 can be rotated synchronously by controlling the operation of the rotating motor 114. The bracket 101 ensures that the turntable 102 can rotate smoothly. The electric heating tube 116 is started to generate heat, so that the temperature inside the drying tube 103 increases, thereby drying the material on the turntable 102. The drying tube 103 forms an integral channel through the connecting tube 104, so that the heat can be transferred between each drying tube 103. The moisture and the air with lower temperature generated in the drying process are discharged by the circulating fan 105 and enter the circulating pipe 106. The condenser 108 cools the moisture, condenses the moisture and discharges it. The treated drier air returns to the connecting pipe 104 through the circulating pipe 106. The exhaust fan 109 faces upward and evenly disperses the treated dry air into the drying pipe 103. The guide motor 113 controls the sprocket 110 to rotate, so that the drying pipe 103 rotates, and the position of the guide head is changed to achieve uniform drying of different positions of the material.
