Considering that the outer wall of the container to be cleaned is stuck with dust, impurities, materials and the like, which causes the outer wall of the container to be dirty, the outer side of the container needs to be cleaned no matter the container is transferred to the high-pressure cleaning station M or the low-pressure cleaning station N, so as to ensure the cleanliness of the outer side of the container.
When the container is used, different materials are contained in the same container, and the inner side of the used container needs to be cleaned in order to prevent the materials occupied in the inner side of the container from influencing the next use of the container. For improving the cleaning effect, can carry out the high pressure cleaning operation to the container that is transferred to high pressure cleaning station M and goes out, can wash away the material of the inboard adhesion of container through high pressure cleaning liquid, guarantee the inboard cleanliness factor of container to, when the container is used once more, can effectively avoid leaving over the material of container inside last time and cause the pollution to the material that next time the container held, consequently, guaranteed the purity of material, prevent that the material from being polluted.
Besides the mode, the container transferred to the low-pressure cleaning station N can be subjected to low-pressure cleaning operation, materials adhered to the inner side of the container are washed away through low-pressure cleaning liquid, and the cleanliness of the inner side of the container is guaranteed. The mode can prevent the material from being polluted and ensure the purity of the material.
It should be noted here that, a corresponding cleaning manner may be selected according to the type of the material contained in the container, and specifically, when the container contains a first type of material (e.g., a material with a high viscosity and difficult to clean), the container may be cleaned by a high pressure cleaning manner; when the container contains a second type of material (e.g., less viscous, material that the container has been cleaned from, etc.), it may be cleaned using a low pressure cleaning process, which may improve the applicability of the cleaning process. In some cases, the low-pressure cleaning operation can be performed again after the high-pressure cleaning operation is completed, so that the cleaning effect is further improved, and the cleanliness of the container is ensured.
After the cleaning operation is completed, the inner side of the cleaned container is dried to remove the cleaning liquid adhered to the inner side of the container, so that the inner side of the container is ensured to be dry, and the cleaning liquid can be effectively prevented from causing adverse effects on the material to be contained in the container.
In the embodiment of the application, firstly, a container to be cleaned is transferred to a high-pressure cleaning station M or a low-pressure cleaning station N according to actual conditions, the outer side of the container positioned at the high-pressure cleaning station M or the low-pressure cleaning station N is cleaned to ensure the cleanness of the outer surface of the container, the inner side of the container positioned at the high-pressure cleaning station M is cleaned at high pressure, and the inner side of the container positioned at the low-pressure cleaning station N is cleaned at low pressure, so that various different cleaning modes can be realized, the cleaning range is expanded, and various cleaning requirements are met; and after the cleaning step is finished, drying the inner side of the container to accelerate the drying efficiency of the container.
Based on the arrangement, the cleaning method in the embodiment of the application can realize multiple cleaning modes to enlarge the application range, and is convenient for cleaning in corresponding cleaning modes after different materials are contained in the container, so that the cleaning effect is improved, and the cleaning standard is convenient to achieve; in addition, the cleaning efficiency and the cleaning effect can be improved by combining various cleaning modes; meanwhile, compared with a manual cleaning mode, the cleaning method in the implementation of the application can realize automatic cleaning, the labor intensity of workers is reduced, and the cleaning efficiency is improved.
