Abstract
Vanes of blower are heated to 200-400 deg.c homogeneously, and heated vanes are shrunk on rotating shaft, which is then placed fluidized bed box. While the blower in the fluidized bed box is turned on, the shaft with vanes rotates inside the fluidized bed box in even speed clockwise and counterclockwise alternately, so that the dispersed, heated and melted plastic powder adheres onto the vanes to reach required thickness. Compared with available technology, the present invention is simple, low in cost and obvious in anticorrosive effect.
Description
The present invention relates to a kind of method that on impeller of blower, applies the anti-rot plastic coating; this kind method can apply the thick plastics corrosion protective covering of one deck 1-3MM on impeller of blower; thoroughly solve impeller of blower because of seriously corroded greatly influences the problem in its service life, belonged to the anticorrosion engineering technical field.
At present in factory and various engineer operation, particularly under some more abominable environments for use, employed a large amount of blower fan all can not reach useful life because of the corrosion-resistant of its fan blade, the shortest used several days sometimes and just scrapped, changing fan blade has not only increased the running expense of equipment in large quantities, but also influenced the use of blower fan, and caused the stopping production of whole production line or system, bring tremendous loss to production.For a long time, this problem is perplexing manufacturing enterprise always, in order to address this problem, in the past few years, the technical staff adopts the whole bag of tricks, as adopting the surface treatment that applies various corrosion-inhibiting coatings or corrosion-resistant effect is arranged on fan blade, but all obtains satisfied effect, so the anticorrosion problem of impeller of blower is the problem that present manufacturer and user very press for solution.
Purpose of the present invention designs the anti-corrosion method that a kind of new impeller of blower is provided just at existing problem in the above-mentioned production; this kind method can apply the thick plastics corrosion protective covering of one deck 1-3MM on impeller of blower; this protective layer is covering to be connected closely with the fan blade matrix and also can support the erosion of pre-various chemical attack environment to fan blade; improved the service life of impeller of blower widely; thereby saved the expense of a large amount of replacing fan blades; improved production efficiency, economic effect is fairly obvious.Test in manufacturer at present, effect is fine.
The objective of the invention is to realize by following measure:
This kind applies the method for anti-rot plastic coating on impeller of blower; its objective is and on impeller of blower, apply the thick plastics corrosion protective covering of one deck 1-3MM; the service life of utilizing the performance of the good resist chemical of this material of plastics to improve fan blade; for realizing this purpose; institute carries out the technology work step and is suddenly; earlier impeller of blower integral body evenly is heated to 200-400 ℃; the impeller of blower of heat penetration is sleeved on the axis of rolling and fixedly connected with it and its integral body is placed in in the sulfuration bed case of dress plastic powders; start the air blast of sulfuration bed case bottom; the axis of rolling of average rate rotation simultaneously drives fan blade and rolls in sulfuration bed case; roll mode is clockwise and hockets counterclockwise; when the plastic powders back of having splashed covers on impeller of blower because of melted by heat and when reaching desired thickness, takes out and promptly finish whole technical process after fan blade is cured processing.Fan blade after handling like this; its surface covers layer of even plastics anticorrosive coat firmly, and it can protect impeller of blower to avoid the corrosion of chemical gas when work, has prolonged the service time of fan blade widely; for enterprise has reduced the expense of a large amount of replacing impeller of blower, production cost is reduced.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the constructional device schematic diagram of the invention process process
Fig. 2 is the side schematic view of Fig. 1 constructional device
Below with reference to drawings and Examples the inventive method is further described:
Referring to accompanying drawing 1; shown in 2; apply the method for anti-rot plastic coating on the impeller of blower of the present invention; its objective is and on impeller of blower, apply the thick plastics corrosion protective covering of one deck 1-3MM; its procedure of processing is; impeller of blower 1 integral body with steel evenly is heated to 300 ℃ earlier; continue for some time so that with the whole workpiece heat penetration; can keep a fixing temperature value like this on its fan blade surface for a long time; be sleeved on the axis of rolling 2 impeller of blower of heat penetration also fixedly connected with it; in afterwards its integral body being placed on the sulfuration bed case 4 of the plastic powders 3 of dress polyethylene material; the axis of rolling 2 is inlaid in the open slot 6 that vulcanizes on the bed case 4; start the air blast 5 of sulfuration bed case 4 bottoms; average rate is rotated the axis of rolling 2 simultaneously; suit fan blade thereon will roll in sulfuration bed case 4 under its drive; roll mode is clockwise and hockets counterclockwise; the velocity of rotation of the he 2 of rolling is 15 rev/mins; at this moment; plastic powders in the sulfuration bed case 4 has been splashed because of the wind-force of air blast; in the time of on covering impeller of blower; because of melted by heat covers on its surface; and pile up thickening gradually; the grain fineness of plastic powders is less than 60 orders; like this; it will be at an easy rate under the effect of air blast wind-force, is dispersed on the impeller of blower equably and forms the uniform coating of a layer thickness, for reaching desired 2MM thickness; the needed time of rotation process should be controlled at 6-7 minute; afterwards, take out fan blade and be cured processing, the above-mentioned complete technological that is technical scheme of the present invention.
Adopt the impeller of blower that is coated with the plastics anticorrosive coat of technical method production and processing of the present invention in actual production, to test, obtained good effect.Because the improvement of anticorrosive measure can extend to 6-12 month the service time of fan blade.
Method and the existing skill that applies the anti-rot plastic coating at impeller of blower of the present invention Art compares that to have production technology simple, and processing cost is low, and obvious in anticorrosive effect can be greatly Improve the service life of product, for enterprise has saved a large amount of equipment operating costs.
