Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and in particular relates to a mobile drying arm used for drying tank trucks. Background Art

[0002] A tank truck is a large road truck primarily used for the transportation and storage of chemicals and petroleum derivatives (such as gasoline, diesel, crude oil, lubricating oil, coal tar, and other oils). During long-term use, impurities, sediments, and rust in the products will gradually accumulate inside the tank. These substances may not only clog the pipes but also corrode the tank, thereby shortening the service life of the tank truck. Cleaning a tank truck can remove these impurities and sediments, protecting the equipment and extending its service life. Cleaning can also ensure the cleanliness of the interior of the tank, reduce the impurity content in the product, and thus improve product quality. After the tank truck is cleaned, it is necessary to clean the tank truck because a small amount of water will remain on the inner wall and bottom of the tank. If this water is not removed in time, it may lead to a decline in product quality.

[0003] Chinese patent publication number CN208450017U discloses an intelligent, high-pressure, three-dimensional cleaning device that dries tank trucks using a high-temperature drying unit. The drying unit includes a high-temperature air supply connected to a high-pressure gas jet head via a high-pressure air pump. The three-dimensional cleaning head and the high-pressure gas jet head are mounted on an intelligent control vehicle via a suspension bracket. However, the high-temperature drying unit is complex and can only bend. Forward and backward movement requires the high-pressure jet cleaning unit and the intelligent control vehicle to move as a whole, resulting in limited flexibility.
