Technical field
This utility model is related to spraying technology field, more particularly to a kind of to fill for the recycling of thermal spraying residual powder Put.
Background technology
Plasma spray technology is an important technology in Surface Engineering, and surface peening and protective action are played to workpiece, tool There is thermal spraying material to enrich, surface can be given with wear-resisting, anti-corrosion, resistance to high temperature oxidation and various work(such as high temperature wear, heat-insulated, insulation Can, stronger advantage is shown in terms of the increasingly harsh multiple requesting in modern project structural elements surface is solved.
Dusty material is the most commonly used sprayed on material in current thermal spraying, is needed a certain amount of powder before thermal spraying Pour in dust feeder, then by powder feeding gas such as compressed air or noble gases in spraying process, in making powder feeder device Powder with air-flow by powder feeding pipe from nozzle enter Yan Liu centers, powder particle by flame stream heating and melting or soften for melting or Semi-molten particle.At the same time, melting or semi-molten particle are accelerated by flame stream, and with certain speed impacts to by protect the substrate Surface forms flattening particle, and substantial amounts of flattening particle has the coating of specific function in the continuous formation of deposits of matrix surface.
Dusty material consumption in plasma spray technology can't realize accurate calculating at present, it will usually add in dust feeder Enter excessive dusty spray material, with avoid passing in and out repeatedly carry out between spraying operation plus powder caused by spray coating operations efficiency reduce with And operator pass in and out the injury problem caused to body between spraying operation repeatedly.But it is past in spray equipment after spraying terminates Toward the remaining a certain amount of dusty material of meeting.In cleaning dust feeder, remaining dusty material mainly has two methods at present:First Kind be powder feeding pipe is unloaded from spray gun after, remaining powder in dust feeder is directly discharged in air using powder feeding gas, Substantial amounts of dust can be produced in this process, not only cause the waste of powder, the pollution of environment, thermal spraying operator employee Make the deterioration of environment, and substantial amounts of dust after thermal source is run into it may happen that explosion accident;Another kind is exactly using installation Remaining powder in dust feeder is sucked out by the extractor fan of blower fan, (the application of the clear powder device of such as aspiration self-cleaning type covering Number:201520725855.0), a kind of pulsed dust-precipitator overflow powder recovering device (application number:201620013480.X) and A kind of environment-friendly metal Powder Recovery processing equipment (application number:201521084957.5), although these devices avoid powder The pollution to environment is directly discharged in air, but powder is easily polluted by the other materials in device, is sprayed again Occurring unfavorable element during coating can be caused during use causes the decline of coating performance, therefore the thermal spraying residue powder that the method is reclaimed End can not recycle, and cause the waste of powder, and current apparatus structure is complicated, need to consume electrical energy drive, result in The raising of thermal spraying production cost.
Utility model content
The purpose of this utility model is for thermal spraying residual powder recycling high cost present in current techniques And easy contaminated and unavailable deficiency during the recovery of thermal spraying residual powder, there is provided a kind of thermal spraying residual powder is reclaimed Reuse means.Design of the device by physical filtering method twice, it is possible to use distilled water is by residual powder and powder feeding gas Body is separated, and powder feeding gas enter air after filtering, and the mixture for obtaining distilled water with thermal spraying residual powder is through strainer filtering Obtained not by the powder of other Substances Pollutions afterwards, realize thermal spraying residual powder recycling.
The technical solution of the utility model is:
A kind of thermal spraying residual powder recycling device, the device include:Air inlet pipe, recycling bin, distilled water, filtration Net, escape pipe, recovery bung and sealing ring;
The upper edge of described recycling bin is provided with the horizontal terrace with edge of protrusion, is provided with sealing ring on horizontal terrace with edge, bolt by Top to bottm sequentially passes through recovery bung, sealing ring and horizontal terrace with edge, by three's airtight connection;Be separately installed with recycling bin lid into Trachea and escape pipe, air inlet pipe one end are connected with powder feeding pipe, and the other end is inserted in distilled water, and escape pipe is located at distillation aqueous The top in face, it is internal that drainage screen is housed.
3~5 screws are evenly distributed with described horizontal terrace with edge, the diameter of bung and the diameter phase of horizontal terrace with edge is reclaimed Together, and mutually existing together with horizontal terrace with edge it is provided with matching screw.
Described air inlet pipe is provided with Self-locking rapid joint with the connection end of powder feeding pipe.
The beneficial effects of the utility model are:
Relative to directly discharge and installation cleaning of the blower fan apparatus to thermal spraying residual powder in dust feeder at present, this reality With the new recycling realized by the method for physical filtering to thermal spraying residual powder.This utility model simple structure, It is workable, any energy, energy-conserving and environment-protective, and whole process cleaning are not consumed, powder is not contaminated, and realizes powder Recycling, it is to avoid the waste of powder, the pollution of environment, the deterioration of thermal spraying operator's working environment, and in a large number Dust after thermal source is run into it may happen that explosion accident.The production cost of plasma spray technology prepares coating is reduced, favorably In the further genralrlization application of plasma spray technology.
