[0019] In order to better understand the present invention, the present invention is further described below in conjunction with specific embodiments. Example 1

[0020] Combination Figures 1 to 3 From the perspective of the present invention, the cable protection tube sample cleaning and drying device comprises a first sample conveyor belt 1, which conveys a material box carrying one or more samples to a cleaning and drying mechanism, wherein the cleaning and drying mechanism comprises a cleaning and drying chamber 2 that matches the size of the material box, and the cleaning and drying chamber 2 cooperates with the material box to form a cleaning and drying space; and further comprises a high-pressure nozzle 3 and a high-pressure air gun outlet 4, wherein the high-pressure nozzle and the high-pressure air gun outlet are both arranged at the top of the cleaning and drying chamber, such as Figure 2 As shown in , it can be seen that in this embodiment, further preferably, the high-pressure nozzles are provided with two, the high-pressure air gun air outlet is provided with one, and the high-pressure nozzle and the high-pressure air gun air outlet are arranged on the same straight line, and the straight line is the long axis of the cleaning and drying chamber. Figure 2 As shown in , the high-pressure nozzle and the high-pressure air gun are arranged at equal intervals.

[0021] Back to Figures 1 to 3 From the perspective of the embodiment, the tail of the high-pressure nozzle is connected to the water pump 5, and also includes a clean water tank 6. The water outlet of the clean water tank 6 is connected to the water pump, and the water inlet of the clean water tank is connected to the clean water source; the tail of the high-pressure air gun outlet is connected to the high-pressure gas tank (not shown in the figure); the cleaning and drying chamber 2 is fixed to the bracket 7 and realizes up and down movement through the cylinder 8, combined with Figure 2It can be seen that the upper part of the cleaning and drying bin 2 is connected with a cylinder 8, and the bottom of the inner tube of the cylinder 8 is fixed on the cleaning and drying bin. When it contracts, it drives the cleaning and drying bin to move upward, and when it extends, it drives the cleaning and drying bin to descend. During this process, the small columns next to it can slide in the corresponding through holes; it also includes a cleaning and drying bin driving system, and the cleaning and drying bin driving system controls the up and down movement of the cleaning and drying bin; the material box 9 is a topless box body with mesh; it also includes a wastewater tank 10, and the wastewater tank 10 is arranged below the material box; it also includes a second sample conveyor belt 11, combined with Figure 1 and Figure 2 It can be seen that the first sample conveyor belt and the second sample conveyor belt are respectively located on both sides of the cleaning and drying chamber, and the second sample conveyor belt conveys the cleaned and dried samples to a storage place for standby use.

[0022] In this embodiment, as a preferred technical solution, a water purification filter 12 is also provided, the water inlet of the water purification filter is connected to the water outlet of the wastewater tank, and the water outlet of the water purification filter is connected to the water inlet of the water purification tank, thereby forming a circulating water filtration system, saving water resources and sample preparation costs.

[0023] In this embodiment, we use a duckbill high-pressure nozzle to form a fan-shaped water mist, and through the rotation of the duckbill high-pressure nozzle, it can form a fan-shaped water mist with a vertex angle of 120-160° in all directions. At the same time, a circular high-pressure air gun outlet is selected to form a conical wind, and the air pressure of the high-pressure air gun outlet is adjusted to 650-750pa by controlling the valve at the high-pressure cylinder.

[0024] Next, we will describe how the present invention cleans and dries the sample in combination with the above-mentioned mechanism.

[0025] First, the sample is placed in the material box and reaches the cleaning and drying mechanism through the first conveyor belt. The cleaning and drying chamber is driven by the cleaning and drying chamber drive system and descends to the material box through the action of the screw and the cylinder. Since the material box is topless and the cleaning and drying chamber is bottomless, as the cleaning and drying chamber continues to descend, its top closes the top of the material box to form a closed cleaning and drying space.

[0026] Then, the water pump pressurizes and sprays clean water from the high-pressure nozzle, which rotates in a fan-shaped form with a specific vertex angle, which can not only ensure the water pressure, but also ensure the cleaning range, so that no matter where the sample is placed in the material box, it can be cleaned. The wastewater generated during the cleaning process falls from the mesh of the material box into the wastewater tank below.

[0027] After cleaning, open the high-pressure gas tank, and high-pressure gas will be ejected from the air outlet of the high-pressure air gun, taking away the water remaining on the surface of the sample and completing the drying.

[0028] The dried sample can then enter the second conveyor belt for standby use.

[0029] The generated wastewater enters the water purification tank after being filtered by the water purification filter, and can be reused repeatedly to save water resources. The water purification filter can be selected from existing brands and models according to needs.

[0030] In this field, we know that to prepare a test sample, it is necessary to first mill the sample from a section of the cable protection tube to be tested, then grind it, and finally clean and dry it before it can be used for testing. Therefore, the aforementioned cable protection tube cleaning and drying device can be combined with a cutting device and a grinding device to form a fully automatic sample preparation line, thereby completing fully automatic sample preparation.

[0031] The above is a specific implementation of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the protection scope of the present invention.
