Embodiment Construction

[0012] The present invention includes a phosphating working tank 6, a lifting pump 7, a lifting pipeline 8, and a settling tank. The phosphating working tank 6 is connected to a settling tank through the lifting pipeline 8, and the settling tank includes an automatic liquid replenishment tank 1 and a plurality of connected settling tanks 2. The automatic liquid replenishment tank 1 is connected with the lifting pipeline 8; the settling tank 2 is separated by multiple baffles 4 arranged on the upper and lower sides of the settling tank 2; several filter bags 3 are arranged in the first settling tank, and the liquid replenishing tank The phosphating solution in 1 flows into the filter bag 3 through several pipelines equipped with flow control valves; the terminal settling tank 2 is provided with a return pipe 5 communicating with the phosphating working tank 6 .

[0013] The filter bag 3 is a multi-layer filter bag 3 structure, wherein the automatic liquid replenishment tank 1 pi...

Abstract

The invention relates to an efficient cyclic purification and phosphorization device. The device comprises a phosphorization operating tank, a lifting pump, a lifting pipe and a settling box, wherein, the phosphorization operating tank is communicated with the settling box via the lifting pipe; the settling box comprises an automatic liquid supplementing tank and a plurality of interconnected settling tanks, and the automatic liquid supplementing tank is connected with the lifting pipe; the settling tanks are separated by a plurality of upper flow baffle plates and lower flow baffle plates which are alternately arranged in the settling tanks; the first settling tank is internally equipped with a plurality of filter bags, and phosphating liquid in the liquid supplementing tank flows into the filter bags through a plurality of pipes with flow control valves; and the settling tank on the tail end is internally equipped with a return flow pipe communicated with the phosphorization operating tank. The efficient cyclic purification and phosphorization device has the following advantages: 1. the phosphating liquid is in a circular flow state, and workpieces in the phosphorization operating tank are phosphorized under a stable state; 2. the tank does not need to be cleaned everyday, thus saving manpower and electricity fee; and 3. phosphorated slag filtered by the filter bags can be naturally air-dried, solid is collected in little storage space, and the effective phosphating liquid and the cloth bags can be still recycled, thus achieving the dual-purposes of protecting environment and saving resource at once.

Description

technical field [0001] The invention relates to a chemical waste recycling device, in particular to a phosphating tank device. Background technique [0002] Metal workpieces need to be immersed in phosphating solution for phosphating treatment before painting. At the same time, very fine residue particles will be suspended in the bath during the displacement reaction, which not only affects the performance of the bath but also damages the phosphating quality of the metal surface. Phosphating slag must be removed in time. [0003] In order to solve the above problems, the original phosphating tank device includes a phosphating working tank, and the phosphating working tank lifts the treated phosphating solution to the phosphating solution sedimentation tank through a water pump and a lifting pipeline, and then returns to the phosphorizing solution through the return pipeline. Phosphating working tank; in factory use, the working process is: the phosphating tank liquid is pump...
