Description

Pipeline structure of phosphating filter Technical Field The utility model belongs to the technical field of phosphating filter equipment, and relates to a pipeline structure of a phosphating filter. Background Along with the economic development, the demand of the phosphating filter is extended to various electroplating equipment. The traditional phosphating line adopts a single phosphating filter to be matched with a phosphating tank for use, so that most phosphating filtering requirements can be met. Along with the increase of phosphating productivity and the number of phosphating tanks of a single production line, users of phosphating filters in various industries have put forward the requirement of filtering one-to-two. The traditional phosphating filter pipeline design can not meet the requirement, and the cost of a user can be increased. Disclosure of Invention The utility model aims at the problems and provides a pipeline structure of a phosphating filter, which can meet the filtering requirement of one-to-two phosphating filters, improve the utilization rate of the phosphating filter and reduce the running cost of a user. According to the technical scheme of the utility model, the pipeline structure of the phosphating filter is characterized by comprising at least two phosphating tanks which are arranged in parallel, wherein each phosphating tank is respectively connected with a blanking pipe, the lower end of each blanking pipe is summarized to a blanking main pipe, and the blanking main pipe is connected to an inlet of the phosphating filter; The outlet of the phosphating filter is connected with the outlet main pipe of the filter, the outlet main pipe of the filter is connected with the middle part of the pipe body of the outlet branch pipe of the filter, the two ends of the outlet branch pipe of the filter are respectively connected with the middle part of the pipe body of a conveying pipe, the outlet branch pipe of the filter divides the conveying pipe into a branch pipe of a phosphating tank and a branch pipe of a sewage disposal, the upper end of the branch pipe of the phosphating tank extends into the phosphating tank, and the lower end of the branch pipe of the sewage disposal is connected to a main sewage disposal pipe. As a further improvement of the utility model, the blanking pipe is provided with a first ball valve, a first pneumatic ball valve and a first check valve in sequence along the blanking direction.
