Description

Foam utilizes pulverizer again

Technical field

The utility model relate to a kind of foam is pulverized and extrusion molding after the foam that utilizes again utilize pulverizer again.

Background technology

Usually, foam only is below 0.1% of rubbish weight.Most bubble wrap material is included in the municipal refuse, and this is owing to discharge from family and office.In Europe, municipal refuse account for whole solid waste about about 5%, remaining 95% by agricultural product, paper, fiber, and other rubbish constitute.When converting with weight, plastics account for 7～7.5% of whole municipal refuse, lack than glass and metal, and are still less more a lot of than paper.

A lot of people think that volume of foam is big, thus be the main component of rubbish, but foam can be by pulverizing and fusion and reduced volume is utilized again now.But, still need reutilization technology, in order to manage the foam discarded object efficiently, the central government, commune, enterprise and consumer's cooperation is a necessary condition.

Foam produce ground by reduced volume, re-use, energy recovery etc. utilizes again.According to the amount and the composition of the foam rubbish of collecting, can use the reutilization technology of various ways.Developing bottom tissue that promote to collect such foam and promotion mechanism to the demand of regenerate.Should be realized that reutilization technology can improve the value of reconstituted product the biglyyest, the minimizing of the resource that on the other hand, foam can be realized carrying, classifies, need in the washing etc.

In particular, if use is compared with the value of the final products that utilize again, environment is produced the method for bigger influence, be very wrong.Even utilize again, also to compare environment and recycle value and select correct method, this is very important.

For the most important recycle value of plastics be, not the degree of mixing with the rubbish of other plastics or other form.Utilize method as follows again, after promptly pulverizing foam, mix with new material and make new formed products, and by fusion and squeeze out the method that foam obtains polystyrene, in addition, also have by fusion and squeeze out foam and make polystyrene resin, be used for the method for bath mat, synthetic resin material, toys and clothes hanger etc.In addition, also comprise the method for destroying long strand and making product, so that in refining or petrochemistry operation, utilize again.That is, make oil, can be utilized as the feedstock oil that is used for gasification process and other refining step again by the long condensate of hot pulverizing process conversion.But, this field or starting stage, consider the expense height from economic angle, and the integrated demand of crude oil do not produced special influence.Foam has and feedstock oil heat much at one, is the efficient resource that reclaims heat energy by burning.Begun to make great efforts exploitation energy recovery technology in a lot of countries, particularly Denmark, Switzerland, the burning ratio of municipal refuse reaches 80% (81.4% of current Korea S depends on and buries) recently.These countries develop the standard of exhaust gas discharging control system that human and atmosphere is not produced the burning field of baneful influence.

Particularly, describe as the utilization again of front to useless foam, the fusion deposed polystyrene comes reduced volume by pulverizing also basically, so that utilize again, but, become big with the pulverizer size of the useless foam that is used to pulverize large volume, the problem that exists the size of integral device to maximize.And, in method for reduced volume to utilizing stage carrying and the pulverized useless foam of keeping again, in the stage of molten foam, because the pressing method of useless foam is enforceable, and,, cause the change in physical of useless foam owing to need the rising melt temperature, cause the material distortion thus, this becomes the main cause of the quality reduction that utilizes goods again.

The utility model content

The utility model is made in order to address the above problem, provide a kind of foam to utilize pulverizer again, do not apply excessive cut-out power and just can form big cut-out vestige sleekly, pulverize useless foam gradually equably, and under suitable temperature, be shaped, obtain to have the foam that utilizes required physical property again.

Foam of the present utility model utilizes pulverizer again, comprising: unpowered conveyer belt, the useless foam of guiding obliquely; Foam transports conveyer belt, transfers the useless foam that is placed on the above-mentioned unpowered conveyer belt forcibly; Crushing wheel, be arranged on the downstream that above-mentioned foam transports conveyer belt, it has the rotating shaft by the drive source rotation, by the cylinder wheel hub with specified diameter a plurality of pulverizing circular blade are installed equally spacedly on above-mentioned rotating shaft, described a plurality of pulverizing circular blade are aligned to " it " font; The shaping compression roller is located at the downstream of above-mentioned crushing wheel, is formed with concavo-convex periphery at side face, is driven by being meshing with each other; And heater, be installed in the above-mentioned shaping compression roller, keep the forming temperature of shaping press roll surface.

And, transport on the conveyer belt at above-mentioned foam of the present utility model, transport tooth with the equidistant chain of arranging, closely contact put into useless foam on the unpowered conveyer belt of equipment body above, can force to transport, and the wheel hub that has an inclined plane by both sides on the rotating shaft of above-mentioned crushing wheel is installed with a plurality of pulverizing circular blade with through hole equally spacedly, and this through hole has the inclined-plane at its two ends; And the pulverizing circular blade of above-mentioned crushing wheel is aligned to " it " font with respect to the oblique installation of the rotating shaft of above-mentioned crushing wheel.

Above-mentioned shaping compression roller is installed with the angle that tilts, and arranges circuitously; And, the periphery of above-mentioned shaping compression roller, its section end face complications are configured as

Shape, and above-mentioned heater is set to heat the surface of above-mentioned shaping compression roller, makes useless foam keep the required temperature of extrusion molding.

The effect of utility model

As mentioned above, the utility model transports conveyer belt by foam and unpowered conveyer belt is forced mobile foam, and, in the disintegrating apparatus that in the past becomes problem, on the rotating shaft that drives by drive source, the pulverizing circular blade of circle is not arranged side by side, but a plurality of pulverizing circular blade is arranged to tilt and equally spaced " it " font with respect to rotating shaft by the cylindrical shape wheel hub.When rotating shaft rotates, pulverize circular blade by continuous parabolic curve shape rotation, the useless foam of cutting sth. askew, make that useless foam is not applied excessive cut-out power just can form big cut-out vestige sleekly, pulverize useless foam gradually, do not become piece or not pulverized remainder, evenly pulverize, and, then useless foam is put between the compression roller that is formed with concavo-convex periphery equally spacedly, pulverized useless foam is shaped under suitable temperature, obtains to have the foam that utilizes required physical property again.
