[0003] The usual method is to inject the prepared pickling solution (such as hydrochloric acid, sulfuric acid, etc.) into the pickling tank, and then immerse the steel workpiece to be galvanized in the pickling solution for a certain period of time. During the immersion process, the pickling solution reacts chemically with the rust and scale on the surface of the workpiece, causing it to dissolve and fall off, thereby achieving the purpose of cleaning the surface of the workpiece.

[0004] However, under the existing technical conditions, the filter screen of the feed pipe may be blocked, which may cause the pickling to be interrupted. Once interrupted, maintenance is required, and the blocked filter screen needs to be cleaned. In order to prevent the filter screen of the feed pipe from being blocked, an additional driving mechanism is usually required to knock the filter screen to achieve cleaning. Although this method can alleviate the problem of filter screen blockage to some extent, it brings a high cost burden. Therefore, a hot galvanizing pickling tank is proposed to solve the above problems. UTILITY MODEL CONTENTS
