Coating pretreatment equipment

Abstract

The invention relates to the technical field of coating equipment, in particular to coating pretreatment equipment which comprises a degreasing zone and a washing zone. The degreasing zone is provided with a degreasing tank, a row of degreasing dripping pipes is arranged above the degreasing tank, a degreasing output pipe is connected with the degreasing tank, a degreasing output pump is further connected with the degreasing output pipe, a degreasing dripping header pipe is further connected with the degreasing output pump, the row of degreasing dripping pipes is communicated with the degreasing dripping header pipe, a degreasing input bottom plate and a degreasing output bottom plate are connected with an opening of the degreasing tank, the washing zone is provided with a washing tank, a row of washing dripping pipes is arranged above the washing tank, a washing output pipe is connected with the washing tank and is further connected to a washing output pump, a washing dripping header pipe is further connected with the washing output pump, the row of washing dripping pipes is communicated with the washing dripping header pipe, a washing input bottom plate and a washing output bottom plate are connected with an opening of the washing tank, and the degreasing output bottom plate is connected with the washing input bottom plate. The coating pretreatment equipment has the advantages that the coating pretreatment equipment can run stably and is high in water utilization efficiency, medicament can be saved, and excellent pretreatment effects can be realized.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to pre-painting treatment equipment. Background technique [0002] The general process of pre-painting treatment is mainly to degrease the workpiece first, and then wash it with water. The degreasing of the existing equipment needs to add some chemicals in the water and then carry out the washing operation, and then bring it into the clean water for washing. Washing area, but because the workpiece will leave a certain amount of liquid medicine after degreasing, it will accumulate the liquid medicine in the degreasing area in the washing tank of the washing area. With long-term washing, the concentration of the liquid medicine in the washing tank will The workpiece cannot be cleaned. In order to prolong the tank change time, it is necessary to continuously inject clean water into the tank to reduce the concentration in the tank, and then drain the overflow water after mixi...

[0002] The general process of pre-painting treatment is mainly to degrease the workpiece first, and then wash it with water. The degreasing of the existing equipment needs to add some chemicals in the water and then carry out the washing operation, and then bring it into the clean water for washing. Washing area, but because the workpiece will leave a certain amount of liquid medicine after degreasing, it will accumulate the liquid medicine in the degreasing area in the washing tank of the washing area. With long-term washing, the concentration of the liquid medicine in the washing tank will It is impossible to clean the workpiece. In order to prolong the tank change time, it is necessary to continuously inject clean water into the tank to reduce the concentration in the tank, and then drain the overflow water after mixing in the tank, so that the injected clean water will not be effectively used. If it is drained, the water consumption of the equipment will increase, resulting in a waste of water. At the same time, the dosage of the medicament is not used effectively, and the medicament will also be wasted. This is a common problem with existing equipment. At the same time, the entire coating The cleaning effect of the pre-installation treatment on the workpiece is not good enough
