Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a test tube cleaning device for food inspection. Background Technology

[0002] In food testing, laboratory personnel use test tubes to store food samples. As a commonly used container for samples, test tubes need to be cleaned before and after use to ensure the accuracy of test results. However, current test tube cleaning methods still have the following shortcomings: First, test tubes are currently cleaned either manually or with equipment. Manual cleaning requires holding the test tubes and using a cleaning brush, which is inefficient and labor-intensive. It is also difficult to ensure consistent cleaning quality, and human factors can easily lead to residual dirt, impurities, and cleaning agents inside the test tubes, affecting subsequent food testing. Secondly, some existing cleaning equipment cleans test tubes by placing them in a container and using a nozzle. However, the water flow impact on the inner wall of the test tube is poor, and the water flow is easily blocked by objects at the installation location, creating cleaning dead spots. As a result, dirt, impurities, and cleaning agents remain inside the test tube. Summary of the Invention

[0003] This invention discloses a test tube cleaning device for food inspection. The operator inverts the test tubes to be cleaned on the outside of the stabilizing sleeve and then installs them inside the storage tank with the help of the lifting rod. The operator controls the water pump to deliver the cleaning solution into the storage tank through the first water inlet pipe until the cleaning solution covers the test tubes. The operator controls the ultrasonic vibrator to vibrate the cleaning solution ultrasonically, and the cleaning brush rotates. At this time, the cleaning solution and the cleaning brush automatically clean the test tubes. After the initial cleaning of the test tube is completed, the threaded rod is controlled to move downwards, and the water pump is controlled to evacuate the wastewater from the storage tank. The water flow, in conjunction with the water pump, is delivered to the inside of the threaded rod. Then, the water flow passes through the flow hole of the threaded rod to perform a secondary cleaning of the inner wall of the test tube. At the same time, the water flow at the first water inlet pipe automatically cleans the inner wall of the storage tank.

[0030] The working principle of this embodiment: When installing the cleaning equipment, the staff first installs a valve on one side of the first water inlet pipe 201 and the second water inlet pipe 203, and installs a two-way valve at the outlet of the water pump 7. Then, the staff installs a storage tank 2, a sewage filter 6, and a water pump 7 on the top of the stabilizing plate 1. A sealing cover is installed on the top of the storage tank 2. A set of cleaning mechanisms 3 is installed inside the storage tank 2. The staff selects the corresponding stabilizing sleeve 501 according to the model of the test tube and installs the stabilizing sleeve 501 in the mounting hole of the stabilizing frame 5. An ultrasonic vibrator 4 is installed inside the hidden shell on one side of the storage tank 2. The staff installs a power supply and controller based on existing technology on the stabilizing plate 1 and electrically connects the power supply and controller to the electric motor 301, the water pump 7, and the ultrasonic vibrator 4, respectively. When cleaning test tubes using the cleaning equipment, the staff inverts the test tubes to be cleaned onto the outside of the stabilizing sleeve 501. The staff then positions the test tubes inside the storage tank 2 using the lifting rod of the stabilizing frame 5. The staff controls the water pump 7 to deliver the cleaning solution into the storage tank 2 through the first water inlet pipe 201 until the cleaning solution covers the test tubes. The staff controls the ultrasonic vibrator 4 to vibrate the cleaning solution ultrasonically. The staff controls the electric motor 301 to drive the threaded rod 303 and the cleaning brush 304 to rotate. During the rotation of the threaded rod 303 and the cleaning brush 304, they move up and down. At this time, the cleaning solution, together with the cleaning brush 304, automatically cleans the test tubes. After the initial cleaning of the test tube is completed, the threaded rod 303 is moved downwards so that the bottom of the threaded rod 303 moves to the sealing hole position of the storage tank 2. The water pump 7 is controlled to pump out the wastewater from the storage tank 2. At the same time, the wastewater filter 6 filters the wastewater. The filtered water is then pumped by the water pump 7 to the positions of the first water inlet pipe 201 and the second water inlet pipe 203. Then, the water flows through the flow hole to perform secondary cleaning on the inner wall of the test tube. At the same time, the water flow at the position of the first water inlet pipe 201 automatically cleans the inner wall of the storage tank 2.
