Description
Technical field
The utility model relates to a kind of ceramic powders used for hot spraying dust feeder, relates in particular to a kind of ceramic powders thermal spraying continuous conveying device.
Background technology
Thermal spraying is class methods of preparation coating, has become material surface protection and one of new technology of strengthening, and it is to utilize thermal source with sprayed on material heat fused or softening, is ejected into matrix surface with certain speed, forms coating.Its matrix almost can be various materials; Comprise organic materials such as inorganic material such as metal, pottery, glass and plastics, timber, paper, cloth; And do not limit workpiece size, and arrive iron tower, bridge greatly, all can adopt thermal spraying to prepare coating for a short time to machine components.Sprayed on material can be a metal material, also can be Inorganic Non-metallic Materials and ceramic-metal composite materials such as pottery.Ceramic thermal spray is meant with the pottery to be the heat spraying method of sprayed on material; It is on the basis of metal material thermal spraying, to grow up; Because ceramic coating has the incomparable excellent properties of many metal materials, so development has been brought into play more and more important effect rapidly in a lot of fields.
Ceramic material can be processed bar and adopt the bar spraying process, also can pottery be processed powder, adopts the powder spraying process.The mode of heating of ceramic thermal spray generally adopts flame heat method or plasma arc heating.
Existing ceramic spraying transport is a disposable powder transport (as shown in Figure 1), and about single powder feeding 1kG, need sprayed after shutting down and adding powder again once more after powder used up, and need add powder 2～3 times in per 8 hours.Equipment needs frequent dismounting, is prone to cause the powder delivery equipment loss; Adding powder need shut down, and shuts down stepmother's temperature and reduces, and needs preheating again, has reduced utilization rate of equipment and installations; Add behind the powder because the difference of parent temperature, cause the difference of coating quality, be prone to cause coming off of coating; Owing to spray the difference of front and back powder height, be prone to cause the difference of powder sending quantity, cause coating layer thickness uneven.
The utility model content
The technical problem that the utility model will solve is: in order to improve the efficient that ceramic powders is carried, guarantee the quality of thermal spraying, the utility model provides a kind of ceramic powders thermal spraying continuous conveying device.
The utility model solves the technical scheme that its technical problem adopted: a kind of ceramic powders thermal spraying continuous conveying device, have vibrating bunker, and be stamped cover plate on the vibrating bunker; Cover plate and vibrating bunker are tightly connected, and the discharging opening of vibrating bunker also has storage bin through the nozzle of powder delivery pipe connection spray equipment; Be stamped the feed bin lid on the storage bin; The feed bin lid is tightly connected with storage bin, and the bottom of storage bin has powder feeding pipe, and insert in the vibrating bunker powder feeding pipe bottom; The powder feeding switch valve is installed on the described powder feeding pipe; The top of storage bin has the last nitrogen carrier pipe that in storage bin, charges into nitrogen, and the top of vibrating bunker has the following nitrogen carrier pipe that in vibrating bunker, charges into nitrogen, and last nitrogen carrier pipe equates with the nitrogen pressure that following nitrogen carrier pipe is carried.
In order to adapt to different powder, described powder feeding pipe is inserted the depth-adjustment joint in the vibrating bunker.
To add the powder number of times in order reducing, to reduce operative employee's labour intensity, the volume of described storage bin is greater than the volume of vibrating bunker.
The beneficial effect of the utility model is; The ceramic powders thermal spraying continuous conveying device of the utility model; Through adopting the ceramic powders continuous conveying device to carry out thermal spraying, can make the continuous non-stop run of ceramic spraying equipment, the operator is time saving and energy saving; Having eliminated because of shutting down the interpolation ceramic powders causes the spraying body temperature to reduce; Need preheating again to cause the defective that temperature is uneven then, avoided variation, thereby guaranteed coating quality because of the different ceramic powders discharge pressures that cause of ceramic powders height before and after the spraying.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of existing ceramic spraying transport.
Fig. 2 is the structural representation of the optimum embodiment of the utility model ceramic powders thermal spraying continuous conveying device.
Among the figure 1, storage bin, 1-1, powder feeding pipe, go up the nitrogen carrier pipe at 1-2,2, vibrating bunker, 2-1, nitrogen carrier pipe down, 3, the powder feeding switch valve.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 2, be the optimum embodiment of the utility model ceramic powders thermal spraying continuous conveying device, comprise having vibrating bunker 2; Be stamped cover plate on the vibrating bunker 2, cover plate and vibrating bunker 2 are tightly connected, and the discharging opening of vibrating bunker 2 connects the nozzle of spray equipment through the powder delivery pipe; Also have storage bin 1, be stamped the feed bin lid on the storage bin 1, the feed bin lid is tightly connected with storage bin 1; The bottom of storage bin 1 has powder feeding pipe 1-1; Insert in the vibrating bunker 2 powder feeding pipe 1-1 bottom, and powder feeding switch valve 3 is installed on the powder feeding pipe 1-1, and the top of storage bin 1 has the last nitrogen carrier pipe 1-2 that in storage bin 1, charges into nitrogen; The top of vibrating bunker 2 has the following nitrogen carrier pipe 2-1 that in vibrating bunker 2, charges into nitrogen; Last nitrogen carrier pipe 1-2 equates that with the nitrogen pressure that following nitrogen carrier pipe 2-1 carries powder feeding pipe 1-1 inserts the depth-adjustment joint in the vibrating bunker 2, and the volume of storage bin 1 is greater than the volume of vibrating bunker 2.
