[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Specific examples are given below.
[0026] like Figures 1 to 4 The bottom wall of the drying box 1 is provided with a plurality of fixed cylinders 14, and a plurality of fixed cylinders 14 are arranged in a circular array at the bottom of the rotating disk 13; a telescopic rod 15 is slidably connected to the middle of the inner wall of the fixed cylinder 14; a storage assembly is provided in the middle of the side wall of the telescopic rod 15; a heating block 16 is fixed to the bottom side wall of the rotating disk 13; the heating block 16 is arranged between the plurality of fixed cylinders 14; a heating pipe 17 is provided on the bottom side wall of the heating block 16; a ventilation assembly is provided in the middle of the side wall of the drying box 1; when working, the inspector opens the door panel 11 to evenly place the chemical inspection samples to be dried into the storage assembly to ensure that the samples are not stacked together, and then closes the door panel 11 to open the ventilation assembly to exchange the air inside and outside the drying box 1. At this time, the inspector turns on the motor 12 again, and the motor 12 The rotating disk 13 at the end starts to rotate. At this time, the multiple fixed cylinders 14 and telescopic rods 15 fixed to the bottom of the rotating disk 13 start to rotate inside the drying box 1 as the rotating disk 13 rotates, causing the samples in the storage assembly fixed to the side wall of the telescopic rod 15 to rotate synchronously. At the same time, the inspector turns on the heating block 16, and the heating block 16 causes the heating tube 17 to start emitting light and heating. The heat energy emitted by the heating tube 17 will radiate to the surface of the sample fixed in the storage assembly and dry it. This step, by setting the motor 12, rotating disk 13, fixed cylinder 14, telescopic rod 15, heating block 16 and heating tube 17, can make the sample fixed in the storage assembly rotate back and forth inside the drying box 1 and be dried by the heating tube 17, so that the sample is heated more evenly, which helps to avoid damage to the sample due to local overheating. At the same time, it can also ensure that the moisture or solvent in the sample can evaporate evenly, and the rotation can make the sample more fully contact with the hot air, thereby accelerating the heat transfer and moisture evaporation.
[0027] like Figures 1 to 4As shown, a fixed plate 2 is fixed to the bottom side wall of the drying box 1; the fixed plate 2 is arranged inside the drying box 1; the fixed plate 2 is tilted; a groove 21 is opened on the top side wall of the fixed plate 2; a roller 22 is fixed to the bottom side wall of the telescopic rod 15; the roller 22 slides inside the groove 21; when working, when the telescopic rod 15 rotates, the roller 22 fixed to the bottom of the telescopic rod 15 will start to slide inside the groove 21 as the telescopic rod 15 rotates. Because the fixed plate 2 is tilted, the telescopic rod 15 will slide inside the fixed cylinder 14 according to the tilt angle of the fixed plate 2 when rotating, so that the telescopic rod 15 15 contracts up and down inside the fixed cylinder 14, so that the sample fixed in the middle of the telescopic rod 15 moves up and down together. In this step, by setting the fixed plate 2, the groove 21 and the roller 22, the sample can not only rotate back and forth inside the drying box 1, but also move up and down. This dynamic drying method can ensure that all parts of the sample can fully contact with the hot air, thereby further accelerating heat transfer and water evaporation. Moreover, through the combination of rotation and up and down movement, the temperature gradient during the drying process can be further reduced, making the temperature of each part of the sample more uniform, thereby improving the uniformity of drying.
[0028] like Figure 1 and Figure 2 The air exchange component includes a first air pump 3; the first air pump 3 is fixedly connected to the side wall of the drying box 1; the middle part of the side wall of the first air pump 3 is fixedly connected to an air extraction pipe 31; the air extraction pipe 31 is arranged outside the drying box 1; the middle part of the side wall of the first air pump 3 is fixedly connected to a first air outlet pipe 32; the first air outlet pipe 32 is arranged inside the drying box 1; the first air pump 3, the air extraction pipe 31 and the first air outlet pipe 32 are connected; the middle part of the side wall of the drying box 1 is fixedly connected to a second air pump 33; the second air outlet pipe 34 is fixedly connected to the second air outlet pipe 34; the second air outlet pipe 34 is arranged outside the drying box 1; the middle part of the side wall of the second air pump 33 is fixedly connected to the suction pipe; the second air pump 33, the second air outlet pipe 34 and the suction pipe are connected; when working, the inspection personnel starts the first air pump 3 and the second air pump 33. At this time, the first air pump 3 will take in fresh air from the outside through the suction pipe 31 Fresh air is drawn in and input into the interior of the drying box 1 through the first air outlet pipe 32. The second air pump 33 will draw out the old air in the drying box 1 through the suction pipe and output it to the outside of the drying box 1 through the second air outlet pipe 34, thereby realizing the exchange of air inside and outside the drying box 1. This step is achieved by setting the first air pump 3, the air exhaust pipe 31, the first air outlet pipe 32, the second air pump 33 and the second air outlet pipe 34. The heat transfer and moisture evaporation can be accelerated by introducing fresh air and discharging the old air in the drying box 1. During the drying process, the moisture on the surface and inside of the sample needs to be continuously evaporated and discharged. This setting can ensure air circulation in the drying box 1, reduce humidity accumulation, and thus improve drying efficiency. At the same time, ventilation can also promote the uniformity of temperature distribution in the drying box 1, reduce temperature gradients, and ensure that all parts of the sample can be fully dried.
[0029] like Figures 1 to 3 As shown, the storage assembly includes a storage rack 4; the storage rack 4 and the telescopic rod 15 are fixedly connected; the storage rack 4 is arranged inside the drying box 1; a storage groove 41 is opened on the top side wall of the storage rack 4; when working, the inspection personnel open the door panel 11, evenly place the chemical inspection samples into the storage groove 41, and firmly fix the storage rack 4 on the side wall of the telescopic rod 15, so that the samples will not easily fall out of the storage groove 41 when the telescopic rod 15 rotates. In this step, by setting the storage rack 4 and the storage groove 41, the samples can be fixed on the telescopic rod 15, preventing the samples from falling due to factors such as vibration or wind during the drying process, reducing the problems of uneven heat transfer and uneven water evaporation caused by sample falling, and further improving the drying efficiency.
[0030] like Figure 1 and Figure 2 As shown, a plurality of reflective plates 5 are installed in the middle of the inner wall of the drying box 1; the reflective plates 5 are made of smooth material; when in operation, the plurality of reflective plates 5 arranged on the inner wall of the drying box 1 will receive the heat radiation emitted by the heating tube 17 and reflect it back to the surface of the sample. In this step, by providing the reflective plates 5, the heat loss emitted by the heating tube 17 can be reduced and the utilization rate of the heat energy can be increased, thereby further reducing energy loss and improving drying efficiency.
[0031] like Figures 1 to 3 As shown, a movable plate 6 is fixedly connected to the middle of the side wall of the drum 22; there are multiple movable plates 6 and they are regularly arranged in a circular array on the side wall of the drum 22; the movable plates 6 rotate inside the groove 21; during operation, when the drum 22 slides inside the groove 21, the multiple movable plates 6 fixed on the side wall of the drum 22 will rotate inside the groove 21. By setting the movable plate 6, this step can reduce the friction generated by the drum 22 and the surface of the groove 21 when moving inside the groove 21, and reduce the speed jam of the drum 22 due to the contact friction between the drum 22 and the surface of the groove 21.
[0032] like Figure 1 and Figure 2 As shown, an observation window 7 is provided in the middle of the side wall of the door panel 11; the observation window 7 is made of transparent material; by setting up the observation window 7, this step allows the inspection personnel to intuitively observe the situation inside the drying box 1, which is convenient for real-time monitoring of the drying process of chemical inspection samples, and timely detection and processing of abnormal situations.
[0033] Working principle: The inspector opens the door panel 11 and evenly places the chemical testing samples to be dried into the storage assembly, ensuring that the samples are not stacked together, then closes the door panel 11 and opens the ventilation assembly to exchange the air inside and outside the drying box 1. At this time, the inspector turns on the motor 12, and the motor 12 drives the rotating disk 13 at the end to start rotating. At this time, the multiple fixed cylinders 14 and the telescopic rod 15 fixed to the bottom of the rotating disk 13 begin to rotate inside the drying box 1 with the rotation of the rotating disk 13, so that the samples in the storage assembly fixed to the side wall of the telescopic rod 15 rotate synchronously. At the same time, the inspector turns on the heating block 16, and the heating block 16 will cause the heating tube 17 to start glowing and heating. The heat energy emitted by the heating tube 17 will radiate to the surface of the sample fixed in the storage assembly and dry it. When the telescopic rod 15 rotates, the roller 22 fixed to the bottom of the telescopic rod 15 will start to slide inside the groove 21 with the rotation of the telescopic rod 15. Because the fixed disk 2 is tilted, the telescopic rod 15 will rotate in the fixed disk 2 with the tilt angle of the fixed disk 2. The fixed cylinder 14 slides internally, causing the telescopic rod 15 to contract up and down inside the fixed cylinder 14, causing the sample fixed in the middle of the telescopic rod 15 to move up and down together. The inspector starts the first vacuum pump 3 and the second vacuum pump 33. At this time, the first vacuum pump 3 will draw in fresh air from the outside through the vacuum pipe 31 and input it into the drying box 1 through the first outlet pipe 32. The second vacuum pump 33 will draw out the old air in the drying box 1 through the suction pipe and output it to the outside of the drying box 1 through the second outlet pipe 34, so that the air inside and outside the drying box 1 is kept clean. The inspector opens the door panel 11, places the chemical testing samples evenly into the storage slot 41, and firmly fixes the storage rack 4 on the side wall of the telescopic rod 15 so that the samples will not easily fall out of the storage slot 41 when the telescopic rod 15 rotates. The multiple reflectors 5 arranged on the inner wall of the drying box 1 will receive the heat radiation emitted by the heating tube 17 and reflect it back to the sample surface. When the roller 22 slides inside the groove 21, the multiple movable plates 6 fixed on the side wall of the roller 22 will rotate inside the groove 21.
