Multifunctional surface treatment pool and its blackening liquid

Abstract

The invention discloses a multifunctional surface treatment pool and a blackening liquid used in the multifunctional surface treatment pool. The multifunctional surface treatment pool comprises a treatment tank, a four-way valve and a controller. A first end opening of the four-way valve is connected to a first check valve by a pipe. The first check valve is connected respectively to a first high-pressure water pump, a water storage tank, a mixing tank and a sedimentation tank by pipes. A second end opening of the four-way valve is connected to a vacuum-pressure pump by a pipe. A third end opening of the four-way valve is orderly connected to a second check valve, a second high-pressure water pump and a mixed liquid storage tank by pipes. A forth end opening of the four-way valve is connected to a water inlet pipe. The water inlet pipe is connected to a water distribution pipe. The multifunctional surface treatment pool has the characteristics of simple processes, reasonable design, low cost and small land occupation area. Through reasonable opening and closing of the four-way valve, the different material tanks and treatment tanks are communicated so that switching is very convenient. The multifunctional surface treatment pool realizes combination of functions of the mixing tank, a water washing tank and an air drying chamber and has multiple purposes and high production efficiency. The multifunctional surface treatment pool greatly reduces blackening liquid spraying treatment time to 3-5min so that the blackening liquid spraying treatment time is greatly shorter than the existing blackening liquid spraying treatment time of 40-80min.

Description

technical field [0001] The invention relates to workpiece surface treatment equipment, in particular to a multifunctional surface treatment pool and blackening solution thereof. Background technique [0002] During mechanical production, many workpieces need to be blackened on the surface, which is to form a dense oxide film on the metal surface to achieve the purpose of isolating air and preventing rust. Taking blackening at room temperature as an example, it is necessary to put the workpiece into the degreasing solution to wash off the grease on the surface of the workpiece, then wash off the degreasing solution, then pickle the workpiece to remove the rust of the workpiece, and then wash it again for blackening treatment. After the workpiece is washed with water, it is blown dry and coated with grease. Due to the many processing procedures, multiple processing tanks (pools) are usually equipped. When processing large workpieces and complex steel components, due to the la...
