Description

Technical Field

[0001] The utility model belongs to the technical field of phosphating liquid production, and particularly relates to a protective feeding platform used in a phosphating liquid production line. Background Art

[0002] In the traditional phosphating liquid production process, zinc oxide, phosphoric acid, nitric acid and the like are used as raw materials and added to a reactor in sequence and stirred to produce the finished phosphating liquid. On the phosphoric acid liquid production line, there are multiple reactors, and the raw materials need to be added to the reactors manually in sequence. The feeding port of the reactor is located on the upper end cover of the cylinder. When adding materials to the reactor supported by the support frame, it is necessary to stand on a workbench used to add materials to each reactor to add materials. When the raw materials are lifted onto the workbench, the guardrail structure on the existing elevator cannot meet the needs of convenient loading and unloading of the raw materials. If an elevator without guardrails is used, there will be safety hazards during the loading process. Therefore, it is necessary to make improvements to the above problems. Utility Model Content
