[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figure 1-2 , the present utility model provides a technical solution for an automatic test tube cleaning device for chemical engineering:

[0022] Embodiment 1:

[0023] According to Figure 1 and Figure 2 As shown, it includes a cleaning tank 1, a brushing unit, and a test tube gripping unit. A partition 2 is hermetically installed in the cleaning tank 1, and a drain hole 10 is provided on one side wall thereof, so that the accumulated water on the partition 2 is discharged through the drain hole 10.

[0024] The brushing unit includes a driving motor 42, a cleaning brush 41, and at least one flushing nozzle 31. A bearing is sleeved on the bottom end optical axis of the cleaning brush 41, and the bearing is installed on the partition 2. The driving motor 42 is installed on the lower surface of the partition 2, and its output shaft is connected to the bottom end of the cleaning brush 41. The cleaning brush 41 is driven by the driving motor 42 to rotate, and the inner wall of the test tube is brushed during the rotation of the cleaning brush 41.

[0025] In this embodiment, the number of flushing nozzles 31 is two. The two flushing nozzles 31 are respectively arranged on the left and right sides of the cleaning brush 41. The flushing nozzles 31 are installed on the partition 2 and are parallel to the cleaning brush 41. The inner wall of the test tube is flushed through the flushing nozzles 31. The water inlet end of the flushing nozzle 31 is installed with a water inlet pipe 32, and the outer end of the water inlet pipe 32 extends out of the cleaning tank 1 and is connected to a water supply pipeline.

[0026] The test tube gripping unit includes a horizontal electric slide 7, a vertical electric slide 8, and a clamp. The vertical electric slide 8 is installed on the slide base of the horizontal electric slide 7, so that the horizontal electric slide 7 drives the vertical electric slide 8 to move horizontally.

[0027] The clamp includes a U-shaped seat 91 and two silicone clamping plates 93 symmetrically arranged in the U-shaped seat 91. The U-shaped seat 91 is installed on the slide base of the vertical electric slide 8. Cylinders 92 are respectively installed on the left and right sides of the U-shaped seat 91. The telescopic ends of the cylinders 92 pass through the side walls of the U-shaped seat 91 and are connected to the silicone clamping plates 93. By the synchronous elongation of the two cylinders 92, the two silicone clamping plates 93 approach each other to clamp and grip the test tube. Under the driving action of the horizontal electric slide 7 and the vertical electric slide 8, the test tubes are successively aligned with the flushing nozzles 31 and the cleaning brush 41, and the inside of the test tubes is flushed and brushed. Thus, it is not necessary for the staff to manually brush the inner walls of the test tubes, reducing the labor intensity of the staff and improving the cleaning efficiency of the test tubes.

[0028] It further includes four guiding plates 5. The four guiding plates 5 are divided into two groups and are respectively arranged on the left and right sides of the cleaning tank 1. A belt conveyor 6 is installed between two opposite guiding plates 5. By providing two belt conveyors 6, one belt conveyor 6 conveys the un-cleaned test tubes, and the other belt conveyor 6 conveys the cleaned test tubes. And under the action of the guiding plates 5, it can prevent the test tubes from falling off the belt conveyor 6.

[0029] During specific use, for an automatic test tube cleaning device for chemical engineering of the present utility model, first, the uncleaned test tubes are vertically placed on the belt conveyor 6 on the right side, and the belt conveyor 6 on the right side conveys the uncleaned test tubes;

[0030] When the test tube corresponds to the fixture, the belt conveyor 6 stops working, and the vertical electric slide 8 drives the fixture to move downward, so that the test tube is located between the two silicone clamping plates 93. Then, control the two cylinders 92 to extend synchronously, so that the two silicone clamping plates 93 approach each other to clamp the test tube;

[0031] After that, control the operation of the horizontal electric slide 7 to move the test tube to the position of the right flushing nozzle 31, and the right flushing nozzle 31 preliminarily flushes the test tube;

[0032] After the preliminary flushing, orderly control the operations of the horizontal electric slide 7 and the vertical electric slide 8 to sleave the test tube outside the cleaning brush 41, start the drive motor 42, and the drive motor 42 drives the cleaning brush 41 to rotate. During the rotation of the cleaning brush 41, the inner wall of the test tube is scrubbed;

[0033] Finally, once again control the orderly operations of the horizontal electric slide 7 and the vertical electric slide 8. After the test tube is secondarily flushed, it is placed on the belt conveyor 6 on the left side after cleaning, and the belt conveyor 6 on the left side conveys the cleaned test tubes.

[0034] Embodiment 2:

[0035] Based on Embodiment 1, the differences are as follows. A plurality of anti-tipping bosses are sequentially arranged on the surface of the belt body of the belt conveyor 6, and a test tube is placed between two adjacent anti-tipping bosses. Under the action of the anti-tipping bosses and the two side guide plates 5, the test tube can be effectively protected, so that the test tube remains vertical during transportation, facilitating the test tube gripping unit to grip the test tube.
