Problems solved by technology

The problem with this pickling method is that when the height of the workpiece is different, the height of the flange of the water heater inner tank from the ground is also different. The greater the height difference between the workpiece, the spraying can not guarantee the liquid medicine sprayed by the pipeline at the bottom. All sprayed into the liner, can not guarantee the quality of pickling

Abstract

The invention provides an automatic water heater inner container spray pickling pretreatment basket special for work-pieces. The basket comprises two frame bodies which are the same in structure and size. The two frame bodies are spaced by a preset distance and are fixedly connected into a whole through a connecting rod. A fixing plate is arranged at the inner side of the bottom face of each frame body. Each fixing plate is provided with three or more work-piece supporting legs which are distributed at intervals and extend into the rectangle; hanging rings are arranged at the outer sides of the upper sides of the frame bodies. The basket has the advantages that the prickling quality is good, and the service life of the basket is long.

Description

technical field [0001] The invention relates to a pretreatment method for automatic spray pickling of a water heater inner tank and a special hanging basket for workpieces. Background technique [0002] At present, the well-known chemical pretreatment method for water heater inner tank is immersion pretreatment. There are two commonly used methods. One is to manually put multiple workpieces into the hanging basket one by one. Manually operate the crane, lift the hanging basket, put the hanging basket together with the workpiece into each liquid medicine tank filled with liquid medicine for cleaning, so as to achieve the purpose of cleaning the workpiece. This method can only put in a fixed number of workpieces each time. While putting in the workpieces, the pre-processing crane needs to wait for the workers to fill the hanging basket before manually lifting the crane for operation. The waiting time is long, which not only affects the production efficiency Low, and a large n...
