In the following description, numerous implementation details are set forth in order to provide a more thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
In addition, the descriptions related to "first", "second", etc. in the present invention are only for description purposes, not specifically referring to the order or sequence, and are not intended to limit the present invention, but only to distinguish the components or operations described in the same technical terms, and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, a cyclone device for inspecting bonding effect of metal powder coating includes a cyclone 1, a dust collector 2, a shut-off fan 3, a collection tank 4 and a feeding device 5.
The cyclone separator 1 is provided with an air outlet, a discharge outlet and a feed inlet, the air outlet of the cyclone separator 1 is connected with the air inlet of the dust collector 2, the discharge outlet of the cyclone separator 1 is connected with the inlet of the air closing machine 3, the outlet of the air closing machine 3 is connected with the feed inlet of the collecting tank 4, and the discharge outlet of the collecting tank 4 is provided with an electronic valve 41.
The feeding device 5 comprises a hopper 51, a feeding motor 52 and a feeding channel 53, wherein the feeding hole of the hopper 51 is arranged opposite to the discharging hole of the collecting tank 4, the discharging hole of the hopper 51 is connected with the inlet of the feeding motor 52, the outlet of the feeding motor 52 is connected with the inlet of the feeding channel 53, and the outlet of the feeding channel 53 is connected with the feeding hole of the cyclone separator 1.
Preferably, the pipe connection between the air outlet of the cyclone 1 and the air inlet of the dust collector 2 and the pipe connection between the feeding passage 53 and the outlet of the feeding motor 52/the feed inlet of the cyclone 1 are both quick-release joints 6, which facilitate the disassembly of the pipes for cleaning.
Generally, the specific gravity of the base powder is larger than that of the metal pigment, and the device utilizes the difference between the specific gravity of the base powder and that of the metal pigment to test the bonding effect of the metal powder, and particularly:
firstly, weighing a certain amount of metal powder coating to be detected, adding the metal powder coating into a hopper 51, then starting a dust collector 2 and a fan 3, and enabling an electronic valve to comprise a closed state; then, starting the feeding motor 52, and uniformly conveying the metal powder coating to be inspected to the feeding channel 53; under the drive of the induced draft motor of the dust collector 2, negative air pressure can be formed in the pipeline, metal powder is brought into the cyclone separator 1 by airflow from bottom to top, and meanwhile, spiral airflow is formed in the cyclone separator 1, and the airflow generates centrifugal force in the spiral process.
In this process, the high-bonding-degree metal powder coating particles are thrown toward the inner wall of the dust collector 2 because the density thereof is greater than that of air, and the high-bonding-degree metal powder coating is discharged into the collection tank 4 by the air shutoff machine 3 under the action of inertia and gravity; and the metal powder coating with low bonding degree is discharged into a collecting tank 4 through a blowing-off machine 3 under the action of spiral airflow, and the metal pigment with low density is wrapped by the airflow generated by the dust collector 2 and enters the dust collector 2, so that the separation of the bottom powder and the metal pigment is realized, and one-time inspection feeding is completed. In order to ensure the bonding effect of the metal powder coating, five to six times of feeding is generally performed, the electronic valve is opened, the metal powder coating and/or the base powder which is collected last time is added into the hopper 51 again, the next time of inspection feeding is performed, and the like.
If the bonding degree of the base powder and the metal pigment is high, the metal pigment in the powder treated by the cyclone separation device is not reduced, and the color of the recovered metal powder coating is not obviously different from that of a metal powder coating of the same batch, so that the bonding effect of the metal powder coatings of the batch is qualified; on the contrary, if the color of the metal powder coating of the batch recovered by the cyclone separation device is different from the color of the metal powder coating of the same batch, the bonding effect of the metal powder coating of the batch can be judged to be unqualified. The bonding effect of the metal powder coating can be tested by testing the cyclone separator 1, so that the quality of the metal powder coating is controlled, and the utilization rate of the metal powder coating is improved.
To sum up, this a cyclone for examining metal powder coating nation decides effect, this device utilize the specific gravity of primer and the difference between metallic pigment's the specific gravity, will not have the metallic pigment that bonds to separate out from metallic powder coating through cyclone, and the inspection of metal powder coating nation decides effect is realized to colour around the contrast processing, and this device simple structure operates simply, effectively, has strengthened metallic powder coating's quality management and control, has improved metallic powder coating's utilization ratio.
