The utility model provides a kind of hopper with non-sticking lining, comprise the hopper body be made up of the Base Material of hopper, described hopper body is provided with the charging aperture for connecting batch mixer and the discharging opening for connecting extruder, the inwall of described hopper body scribbles one deck polytetrafluorethylecoatings coatings, roughness≤3.2 of described polytetrafluorethylecoatings coatings.The utility model utilize the self lubricity of polytetrafluoroethylene (PTFE) material, anticorrosive property, self lubricity to ensure powder is not bonded at its surface, anti-corrosive properties can resistance to acidity necessarily, alkalescence, solvent corrosion etc., and do not affect original material using function.
Description
Technical field
The utility model belongs to processing modified plastics technical field, is specifically related to a kind of hopper with non-sticking lining.
Background technology
In processing modified plastics link, first need plastics and toner, the powders such as additive mix in batch mixer, then plastics and the mixed mixture of powder are joined in double screw extruder through hopper and process.The addition of part powder is lower, but plays vital effect to the performance of final material or color, and join in extruder through hopper after plastics and powder mix, blanking headwall has certain angle of inclination, and surface is comparatively coarse.Current hopper is obvious technological deficiency below existence:
1, due to existing batch mixer material, blanking headwall angle of inclination, surface smoothness problem, part powder is easy to be bonded on batch mixer inwall, cause the actual addition of powder to produce difference with design addition, final material property and color are by certain impact;
2, along with the carrying out of batch mixing operation, on batch mixer wall the powder that glues more sticky more, and As time goes on, the powder sticked on blanking headwall receives the effect of material gravity, powder and blanking headwall adhesion strength more and more higher, produce after terminating and cause certain difficulty to the cleaning of hopper;
3, part powder material has certain weak acid or alkalescent, has hopper to contact for a long time and produces certain corrosivity to hopper.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of hopper with non-sticking lining, and in use not sticky powder, easy to clean, corrosion-resistant.
The utility model is achieved in that
A kind of hopper with non-sticking lining, comprise the hopper body be made up of the Base Material of hopper, described hopper body is provided with the charging aperture for connecting batch mixer and the discharging opening for connecting extruder, the inwall of described hopper body scribbles one deck polytetrafluorethylecoatings coatings, roughness≤3.2 of described polytetrafluorethylecoatings coatings.
Further, the thickness of described polytetrafluorethylecoatings coatings is 3-5 μm.
Wherein, described hopper body can have any shape, such as taper, the cylindrical or cubic bodily form.
Wherein, described basic material is the conventional material of existing hopper, such as alloy cast iron, spheroidal graphite cast-iron or steel alloy etc.
Compared with prior art, the utility model has following beneficial effect:
1, the present invention arranges polytetrafluorethylecoatings coatings on hopper inwall, and powder is not bonded at its surface to utilize the self lubricity of polytetrafluoroethylene (PTFE) material, anticorrosive property, self lubricity to ensure, anti-corrosive properties can resistance to acidity necessarily, alkalescence, solvent corrosion etc.;
2, polytetrafluorethylecoatings coatings roughness≤3.2, ensure that polytetrafluorethylecoatings coatings has higher fineness, contribute to coating and play antiseized powder, result of use easy to clean;
3, polytetrafluorethylecoatings coatings thickness is 3-5 μm, ensure that to have good antiseized powder effect when not affecting original material using function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
With reference to the accompanying drawings, the utility model will be further described in conjunction with specific embodiments, to understand the utility model better.
See figures.1.and.2, a kind of hopper with non-sticking lining, comprises the hopper body 10 be made up of the Base Material 11 of hopper.Hopper in the utility model is the hopper of extruder, and for connecting batch mixer and extruder, play certain bearing effect, its shape is not limit, and can have any shape, such as taper, the cylindrical or cubic bodily form.In the present embodiment, taper is adopted.
Described hopper body 10 is provided with the charging aperture 12 for connecting batch mixer and the discharging opening 13 for connecting extruder, and the inwall of described hopper body 10 scribbles one deck polytetrafluorethylecoatings coatings 14.Utilize the self lubricity of polytetrafluoroethylene (PTFE) material, anticorrosive property, its self lubricity can ensure that powder is not bonded at its surface, and anti-corrosive properties can the corrosion etc. of resistance to acidity, alkalescence and solvent necessarily.
Roughness≤3.2 of described polytetrafluorethylecoatings coatings 14, this ensures that polytetrafluorethylecoatings coatings has higher fineness, contributes to coating and plays antiseized powder, result of use easy to clean.
The thickness of described polytetrafluorethylecoatings coatings is 3-5 μm, this ensures to have good antiseized powder effect when not affecting original material using function, the too thin anti-adhesion effects of coating is not obvious, coating is too thick affect the result of use of Base Material and coating and Base Material adhesion strength not high enough.
Wherein, described basic material is the conventional material of existing hopper, such as alloy cast iron, spheroidal graphite cast-iron or steel alloy etc.
Plastics and powder enter in the process of extruder through hopper mixing through batch mixer, owing to scribbling the coating of one deck polytetrafluoroethylene (PTFE) on the surface of original hopper, and coating has lower roughness, polytetrafluoroethylene (PTFE) inherently has good self lubricity, powder is not easy to be bonded at its surface, to play the effect of antiseized powder, and polytetrafluorethylecoatings coatings has certain anticorrosive property, and part can be prevented to have the corrosion of corrosive powder to hopper.
Because the technical program makes hopper play the effect of antiseized powder, powder is not bonded at hopper surface, and powder is consistent with theoretical addition at the actual addition of process engineering, and then strong mechanical property is improved; Through facts have proved, use the hopper described in this technical scheme, before product performance index deviation is comparable, reduce by 30%.Hopper described in the technical program is due to not sticky powder, and because powder does not stick on its surface after production completes, hopper easy cleaning, blows with compressed air and can reach clean requirement, and clean labour intensity declines 50%.Coating described in the technical program has certain anticorrosive property, prevents from having the pollution of corrosive powder to hopper, and through checking, this technical scheme comparable original technical scheme increases by 10% service life.
Be described in detail specific embodiment of the utility model above, but it is as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present utility model.Therefore, not departing from the equalization conversion and amendment done under spirit and scope of the present utility model, all should be encompassed in scope of the present utility model.
