Description
Technical Field
The invention relates to the technical field of powder metallurgy equipment, in particular to a binder wet-type catcher and a system thereof.
Background
The purpose of adding the binder in the metal powder injection molding technology is to make the dried metal powder be ejected to manufacture a workpiece with a complex shape, but the staged task of the binder after the workpiece is formed is completed and must be removed to avoid the obstruction of the bonding and densification between the powders during the subsequent high temperature sintering.
Currently, in metal injection molding, most of the main binders are high molecular plastics such as Polyethylene (PE), polypropylene (PP), and the like. The workpiece blank (the treatment object of the degreasing process) may collapse, deform or break in the process of removing the binder, so that degreasing adopts a slow and gradual mode, firstly reacts with nitric acid in a catalytic degreasing furnace to be changed into formaldehyde gas to burn out, most of the binder is removed, and a small part of the binder is left for maintaining the shape and not collapsing in the process of conveying the workpiece blank from the catalytic degreasing furnace to a vacuum degreasing sintering furnace. While the remaining binder is mainly a high molecular polymer.
When the vacuum degreasing process is carried out, the furnace is heated to a certain temperature, and the binder in the workpiece blank body is gasified and filled in the material box. The current-carrying protective gas is filled into the furnace, the material box is connected with the degreasing pipeline, the vacuum pump is used for pumping, the pressure P1 in the furnace is larger than the pressure P2 in the material box, the gas is caused to flow unidirectionally, so that the binder vapor in the material box flows into the degreasing pipeline along with the current-carrying protective gas, part of the binder vapor in the gas is collided with the inner wall of the pipeline and is changed into liquid when the binder vapor slowly flows into the grease collecting box, the binder vapor without changing into liquid continuously flows into the grease collecting box along with the current-carrying gas (part of the binder vapor is changed into liquid in the process) to reach the catcher, the catcher is filled with cooling water, the binder vapor is blocked by the multilayer fins, the binder vapor can be changed into liquid when the binder vapor is collided, the catcher and the pipeline are wound with heating wires, and the binder liquid is prevented from being solidified and blocked, and finally the liquid flows into the grease collecting box. The adhesive vapor which is not trapped is led to the vacuum pump together with the carrier shielding gas, passes through the connecting pipe, is partly trapped by the inner wall of the pipe, and is also pumped out together with the carrier shielding gas.
However, in the existing catcher, because the air flow speed is too high, part of the binder vapor easily flows through the gap and is not captured, the part of the binder vapor which is not captured passes through the pipeline, and the part of the binder vapor can touch the inner wall of the pipeline and become liquid when the binder vapor is cooled to be captured, or a small part of the binder vapor finally runs into the cavity of the vacuum pump, and the vacuum pump oil becomes turbid after being mixed with the binder, so that the working capacity of the vacuum pump is influenced, the vacuum degree is reduced, and the service life of the vacuum pump is also influenced. It is usually only possible to replace the vacuum pump oil continuously. If the vacuum oil pump is required to be replaced monthly according to normal production of a full furnace, the cost is high, the oil replacement cost of one furnace is about 1-2 ten thousand per year, and the oil replacement cost of 10 furnaces is 10-20 ten thousand per year. If the customer does not change oil, the vacuum pump is easy to be blocked, and the rotating shaft is broken in severe cases.
The existing trap is a cold well type trap, cooling water is introduced, fins are in a series structure, the distance between the fins is small (the main fat catching principle is to catch fat by increasing air flow strokes by using a plurality of layers of fins, the more the air flows away from an S-shaped structure, the larger the air flow strokes are, the more the catching is), and the smaller the drift diameter is, so that the existing trap is easy to have the problem of blockage.
