[0031] In one embodiment of the utility model, a HFC-227ea storage tank cleaning device with the above structure is used. First, the first storage tank is placed on the storage tank lifting mechanism 3 corresponding to the cleaning mechanism 4. The storage tank to be cleaned passes through the placement slot 7 and falls on the support plate 302, and the tank mouth and the slot 304 are made to correspond. Then, the lifting cylinder 301 is controlled by the controller 8 to extend, driving the support plate 302 to move downward. The support plate 302 moves downward, and the storage tank to be cleaned on the support plate moves downward until the cleaning probe 401 extends into the storage tank to be cleaned. Water is supplied through an external water supply device. The water passes through the water supply hose 404 in turn and enters the cleaning probe 401, and then is sprayed out from the water outlet 402 of the cleaning probe 401, completing the cleaning operation of the storage tank to be cleaned.

[0032] After the cleaning is completed, the controller 8 controls the lifting cylinder 301 to shorten and reset the first storage tank, and then controls the stepping motor 503 to rotate forward 180 degrees through the controller 8, which can drive the rotating shaft 501 to rotate forward 180 degrees under the action of the coupling 504, and the rotating shaft 501 rotates forward 180 degrees to drive the cleaning table 2 to rotate forward 180 degrees, and the cleaning table 2 rotates forward 180 degrees to drive the storage tank lifting mechanism 3 to rotate forward 180 degrees, and the first storage tank on it rotates forward 180 degrees. At this time, the first storage tank corresponds to the air-drying mechanism 6, and at this time, the other storage tank lifting mechanism 3 will correspond to the cleaning mechanism 4. At this time, the air-dried storage tank on the other storage tank lifting mechanism 3 is removed and a new storage tank to be cleaned is installed, and then the lifting cylinder 301 is controlled to extend again through the controller 8, and the air-drying probe 601 is extended into the interior of the first storage tank, and air is supplied by the external air supply device to realize the air-drying operation inside the first storage tank;

[0033] After the air-drying operation is completed, the controller 8 can be used to control the stepper motor 503 to work in reverse 180 degrees, so that the storage tank that has been cleaned and dried can be removed and a new storage tank can be installed. This can be repeated so that the device can simultaneously flush one storage tank and air-dry another storage tank.

[0034] In this process, the annular water retaining edge 104 can prevent turbulence of used cleaning water, and the drainage pipe 106 and valve 107 can be used to centrally collect and process the cleaning water. The annular support seat 105 can support the cleaning table 2 and reduce the load on the rotating shaft 501.

[0035] It is worth noting that the connection and fixation in the present invention can be connected by screw connection;

[0036] In the utility model, the controller 8 controls the lifting cylinder 301 and the stepping motor 503 to work using existing technology;

[0037] In the utility model, the controller 8 controls the stepper motor 503 to work, and the stepper motor 503 works periodically by first rotating 180 degrees forward and then rotating 180 degrees reversely, thereby reducing the possibility of entanglement of the power transmission line of the lifting cylinder 301 on the cleaning table 2.

[0038] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
