Abstract
The utility model discloses a supersonic speed flame plating powder feeding device in a boiler. The electric appliance part of an original powder feeder is moved into a main control tank of the supersonic speed flame plating powder feeding device in the boiler, and only a speed regulating motor, an eight-core control cable interface, a single powder feeding cylinder, a digital voltmeter, a regulation resistance and a flowmeter are included. The electric appliance part of the original powder feeder is separated into the main control tank of the supersonic speed flame plating powder feeding device in the boiler, and double-cylinder power feeding is changed into the single-cylinder powder feeding, thereby not only decreasing the volume and the weight of the original powder feeder, but also reducing influence of the construction environment for the electric appliance, lowering the failure rate of the powder feeder and improving the security of the device in the environment of work high above the ground. The control cable is changed from five cores to eight cores so as to realize the long-distance control and realize the requirement that the powder feeder enters the boiler.
Description
Technical field
The utility model relates to a kind of dust feeder of using the HVAF technology, relates in particular to a kind of and the matching used miniature dust feeder of supersonic flame thermal spraying gun.
Background technology
In the thermal power plant, the economizer tube of boiler, reheater tube, superheater tube, water screen tube (being called for short " four pipes ") are often because of the washing away of the corrosion of high temperature gas stream containing hydrogen sulphide and soot particle, wearing and tearing attenuate, the pipe that more renews is not only time-consuming but also expensive, if cause " four pipes " quick-fried leakage accident, not only can increase the workload of provisional maintenance of power plant and overhaul, and can bring very big economic loss to power plant.According to investigation, high temperature corrosion, the wearing and tearing of boiler " four pipes " have become technical barrier that urgency is to be solved in thermal power plant's safe operation.The HVAF technology is a kind of process that can form coating at material surface expeditiously, its Bond Strength of Coating height, and compactness is good, anti-wear performance is superior, adopts it that boiler " four pipes " is protected, and can prolong its service life greatly, economize on resources, reduce the loss.But, powder feeding machine in the present known supersonic velocity flame plating equipment mainly is made of buncher 1, five cores control cable interface 2, powder feeding tube 3, digital voltmeter 4, potentiometer 5, flowmeter 6, power tube radiator 7, transformer 8, breaker 9, insurance base 11, auxiliary reclay 10, volume is bigger than normal, can't enter boiler internal from boiler maintenance inlet, cause the HVAF technology can't be in boiler The field.
Summary of the invention
The purpose of this utility model is: the microminiaturization of large volume powder feeding machine, realize the HVAF technology is applied in the boiler.
The technical solution of the utility model is: the electrical appliance part of former powder feeding machine is moved in the main control cabinet of supersonic flame sprayer in the boiler, only be made of buncher, eight cores control cable interface, single powder feeding tube, digital voltmeter, potentiometer, flowmeter, the powder feeding tube changes one into by two numbers.
The utility model is separated to the electrical appliance part of original powder feeding machine in the main control cabinet of supersonic flame sprayer in the boiler, bitubular powder feeding makes the monotubular powder feeding into, both reduced the volume and weight of former powder feeding machine, also reduced the influence of construction environment to electrical appliance part, reduce the fault rate of powder feeding machine, improved the security of equipment under the work high above the ground environment.The control cable changes eight cores into to realize Long-distance Control by five cores, can realize that the powder feeding machine enters the requirement in the boiler.
