Abstract
An online copper-removing device comprises a tin pump used for sending tin liquid in a tin jar into a copper-removing jar, the cooper-removing jar which is provided with grids and used for carrying out temperature reduction and copper-removal on the tin liquid, heating boards which are arranged on the side surface and the bottom surface of the copper-removing jar and used for heating the copper-removing device, and a frequency converter used for regulating the rotating speed of the tin pump and controlling the flow rate of the tin liquid, wherein the copper-removing jar is installed beside the tin jar of a tin-spraying machine or a crest welder and divided into four grids of temperature-reduction areas, the external side of the fourth grid is provided with a backflow duckbill extending into the tin jar, the tin pump transmits the copper-containing tin liquid to the copper-removing jar through a metal hose with the speed of 4 to 6 seconds per ounce in the tin jar; after the first grid is filled with the tin liquid, the tin liquid flows into the second grid, the third grid and the fourth grid sequentially, and during the process, the temperature of the tin liquid is gradually reduced to 240 DEG C, the copper is gradually condensed into needle shape and sinks, condenses and accumulates at the bottom of the jar, and tin liquid at the upper layer returns to the tin jar through the backflow duckbill, thus reaching the aim of copper removal, and guaranteeing the continuous and safe production of the tin-spraying machine or the crest welder.
Description
Technical field
The present invention relates to the copper removal equipment of tin-spraying machine or crest welder, especially a kind of online copper-removing device.
Background technology
In the process of using tin-spraying machine production circuit board or crest welder welding plug-in unit, because containing too high copper content, tin liquor can make tin surfaces coarse and be easy to generate unnecessary tin silk wiring board is had bad influence, so be necessary employed tin liquor is carried out copper removal, at present, general copper-removing device (or drift copper device), it is the container made from iron or steel, heater wire is loaded onto in appropriate location in container or outside the container, temp controlled meter and temp probe, can regulate the temperature of tin in the container like this, utilize temperature difference principle that copper is separated with tin, the user only needs with ladle with holes it to be pulled out in container, just can reach the purpose of copper removal; Because this copper-removing device is independent of tin-spraying machine, the workman must put into other containers with the tin liquor in the tin-spraying machine, treat temperature reduce be cooled to solid-state after, block tin could be put in the copper-removing device and be heated up, stir, links such as cooling and copper removal, also tin liquor to be cooled to behind the copper removal and solid-stately can more solid-state tin be put into tin-spraying machine, after treating that block tin dissolves, could begin to produce, front and back approximately need four to six hours (the big low capacity on machine is decided), and in this process, the temperature of tin liquor and machine is all very high, reaches more than 260 degrees centigrade, carries out putting tin in the machine, it all is very dangerous changing tin or transporting the high temperature tin liquor, make the operator injured easily, also waste a lot of times, increased production cost, in addition, because copper content is bigger in the tin liquor before the shutdown copper removal, and the copper content of tin liquor greatly reduces behind the copper removal, and both differ too big, causes spray tin quality very unstable.
Summary of the invention
Need shut down and unsafe deficiency in order to overcome existing copper-removing device, the invention provides a kind of online copper-removing device, this online copper-removing device can guarantee tin-spraying machine or crest welder is continuous, safety in production.

As preferably, the longitudinal baffle of copper removal cylinder divides two groups of cooling areas with the copper removal cylinder, every group of cooling area is divided into two parts by lateral partitions again, constitute four cooling areas, the end face of longitudinal baffle is a step, end face is in the sustained height position around high-order step end face and the copper removal cylinder, and length surpasses the lateral partitions position, be provided with a backflow duckbilled in the outside of the 4th lattice, its groove is far below the end face of copper removal cylinder surrounding, the copper removal cylinder is installed in the tin cylinder next door of tin-spraying machine or crest welder, and the backflow duckbilled stretches in the tin cylinder.
As preferably, end by a metal hose connects tin impeller of pump shell, the other end inserts first lattice in the copper removal cylinder, starter drives the tin pump, the tin liquor of cupric is transported to the copper removal cylinder through metal hose in the tin cylinder, tin liquor is filled with first lattice, because the end face and the copper removal cylinder four limit apical side heights of longitudinal baffle, and length surpasses the position of lateral partitions, so can only flow into second lattice, just flow into the 3rd lattice after the spill-over, after filling with, the 3rd lattice could flow into the 4th lattice, when tin liquor in the copper removal cylinder with 4 to 6 seconds speed process of flowing of every ounce in, the temperature of tin liquor can progressively drop to 240 degree, because the temperature difference relation different with metal proportion, and the copper needle-like of can slowly congealing into, sink to condensing and accumulate in cylinder bottom, comparatively pure above tin liquor is then returned the tin cylinder by the backflow duckbilled, and tin liquor is circulated between stainless steel cylinder and the tin cylinder like this, in two hours under the temperature stabilization control of tin liquor, the workman only needed per two hours to drag for away the needle-like copper that gathers in the stainless steel cylinder, just can reach the purpose of copper removal.
As preferably, the copper removal cylinder is in the ratio casting with 3:1 of the amount of capacity of the tin cylinder of tin-spraying machine or crest welder, to satisfy the amount of dilution proportion requirement of tin-spraying machine or crest welder.
Compare with original technology; the online copper-removing device of the present invention need not shutdown operation; need not the high temperature tin liquor that copper content is high changes; or be transported to other local processing; make production cost descend; the working environment of workers improves; personal safety is protected; and can be from the tin liquor in the tin cylinder sample examination, replenish uneven metallic element such as tin, nickel etc. in the tin cylinder by result of laboratory test, by the copper content of tin sample analysis and Control tin liquor; make the tin liquor quality be guaranteed; and need not to shut down, allow tin-spraying machine or crest welder work always, improved production efficiency.
