Description

Technical Field

[0001] The utility model belongs to the field of oil tank cleaning and sewage discharge, and specifically relates to a tank cleaning and sewage discharge mechanism. Background Art

[0002] With the continuous development of the petrochemical industry, oil tanks are increasingly widely used. During the long-term use of oil tanks, various impurities, sediments, and oil stains will accumulate inside. To ensure the normal operation of oil tanks and the quality of oil products, regular cleaning of oil tanks is an essential step.

[0003] Traditional oil tank cleaning methods often have problems such as low efficiency, incomplete cleaning, and certain environmental pollution. In terms of sewage discharge, challenges such as unsmooth sewage discharge, easy blockage of pipelines, and difficulty in effectively separating impurities are also faced. At the same time, due to the special structure of oil tanks and the characteristics of oil products, high requirements are also put forward for the safety, reliability, and adaptability of the tank cleaning and sewage discharge mechanism. Currently, the design of the pump body in some tank cleaning and sewage discharge mechanisms is relatively complex and requires manual entry into the tank for cleaning, which leads to difficult cleaning situations in actual use, not only affecting the normal operation and maintenance of equipment, but also causing environmental pollution.

[0004] In recent years, although some technologies and equipment have made certain progress in oil tank cleaning and sewage discharge, there are still many deficiencies. For example, some tank cleaning mechanisms cannot well adapt to the cleaning requirements of oil tanks of different specifications, cannot effectively remove fine impurities during the sewage discharge process, or have relatively large energy consumption and resource waste during operation. Therefore, developing an efficient, reliable, and adaptable tank cleaning and sewage discharge mechanism for oil tanks has important practical significance and urgent market demand, can better meet the requirements of the continuous development of the oil tank cleaning industry, improve the technical level and work efficiency of the entire industry, and ensure the safe and stable operation of oil tanks and environmental protection.
