Description

TECHNICAL FIELD [0001] The present invention relates to a half-melting compressor and a method of processing a flammable waste water using the same.

The present invention relates to a semi-molten compressor for melting and reusing a resin so as to be able to reuse waste resin, and a method for processing a combustible wastepaper using the same,

In more detail, unlike the conventional method in which the resin is completely melted and then cooled and cut through a separate cooling device, the regenerating extruder of the present invention is characterized in that the resin is semi-melted at a room temperature of 90 to 300 ° C, And a crushing device and a crushing device are integrally provided in the regenerating extruder so as to maximize the working efficiency and reduce the processing cost, and a half-melting compressor The present invention relates to a method for processing a flammable waste water.

Generally, resin can be recycled through recycling process without incineration in order to save resources and protect the environment because it can be repeatedly molded by applying heat.

As described above, various types of resin extruders are used in order to heat the resin and perform repetitive molding. The most popular extruder is provided with an injection part on one side of the extruder, and a screw rotated by the motor is inserted into the extruder And a shaping head is provided at the end of the extruder main body so that the waste paper injected into the extruder through the injecting part in a state of being crushed in the previous step is conveyed by the rotation of the screw, The molten resin is continuously extruded through an extrusion hole formed in the molding head. The extruded resin regeneration is cured from the cooling means and is recycled into a resin pellet in the form of particles which are crushed by a cutting device and easy to mold. However, since such an extruder has a structure in which heat is externally applied to melt the resin, the efficiency of heat transfer becomes lower as the distance from the heater is increased. Therefore, the temperature is kept constant to melt the resin, .

For example, Korean Registered Utility Model No. 20-0471233, "resin regeneration extrusion apparatus" previously registered by the present applicant, provides a first heater capable of being attached and detached within the shaft of a screw, By providing the second heater in the form of a round bar, the heat conduction is maximized to overcome the problems of the prior art. Accordingly, the heat efficiency is higher than that of the conventional extruder, thereby providing a low-cost high-efficiency melting material.

However, all conventional regenerating apparatuses including the extruder of the present applicant completely melt the extruding screw by heating the extruder screw to extrude the extruded resin as in the case of the above-mentioned universal extruder. As in the conventional technique, when the waste resin is completely melted and extruded, the physical properties of the resin are greatly affected. In addition, a load is applied to the extruder, thereby reducing the life of the device. Further, the completely molten resin must be subjected to a cooling process using a cooling device, and such a cooling device has a problem of emitting environmental pollutants.

Accordingly, it is time to provide a new concept extruder capable of solving the problem of the extruder currently provided.

The present invention is created to more positively solve the above problems. Unlike the prior art in which the waste resin is completely melted and extruded, the recycling rate is high and the change in physical properties of the material can be reduced by half-melting the waste resin. It is a challenge to provide a resin excellent in the quality of the product.

Further, it is possible to reduce the operation ratio of the semi-hot-press apparatus and the waste of unnecessary labor by allowing the resin discharged in the semi-fusion state to be cooled simply by the natural temperature without using a separate cooling apparatus Another challenge.

It is also possible to use a crushing device for crushing the waste paper as an object to be processed, a crushing device for crushing the crushed waste resin into smaller particles, and an extrusion device for compressing the crushed waste resin in a uniform form, And to provide a processing apparatus.

It is another object of the present invention to provide a buffer means capable of suppressing the vibration generated during the crushing / crushing operation of the waste paper when the crushing device, the crushing device and the extrusion device are integrally provided.

Another object of the present invention is to provide a processing device in an integrated form so that the crushing roller can be easily separated so as to remove the trapped waste paper when the waste paper is caught in the crushing device.

According to an aspect of the present invention, there is provided a semi-molten compressor and a method of processing a combustible wastepaper using the same,

The heating temperature of the heater applied to the fused portion is kneaded in a semi-molten state at a normal temperature of 90 to 300 DEG C, To the discharge nozzle (50).

The melting unit 40 includes a melting furnace 41 provided in the form of a pipe having an open circular hollow portion on the top face so as to receive the waste resin falling from the crushing unit 30, A conveying screw 42 having a spiral shape having the same diameter as that of the hollow portion and wound around a motor provided outside the body 10 and rotationally driven in one direction; And a heater 43 which is inserted into the through shaft. The heat is dissipated in the hollow portion through the conveying screw by a motor electrically connected to the heater at a temperature of 90 to 300 ° C.

The discharge nozzle 50 is provided with a plurality of nozzles having different lengths so as to control the time of natural cooling according to the distance through which the semi-molten waste resin is discharged through the nozzle portion, Can be used by replacing.

And a buffer means 60 for suppressing the vibration generated by driving the rollers on the roller shafts provided in the crushing portion 20, the crushing portion 30 and the fused portion 40 by the buffering action of the coil spring And the buffering means 60 is provided for each of the roller shaft holes 14 formed in the front cover 11 and the rear cover 12 of the body 10, (62) protruding from the roller shaft hole (14) so as to prevent the buffering body from being separated from the front cover and the rear cover while maintaining a predetermined distance from the roller shaft hole (14) The support base has two protrusions 63 formed at the same position as the width of the buffer body so as to be coupled with the buffer body, and the coil spring 65 is pulled. By coupling the buffer body to the protrusions, It is characterized by the buffering action of the spring.

In addition, a method for processing a combustible wastepaper using a semi-molten compressor includes a crushing step (S10) of crushing the target waste resin by a pair of crushing rollers (21) The pulverizing step is a grinding step (S20) of pulverizing the waste resin by the rotational action of mutual engagement of the rotating roller 31 made of square projections and the fixed pulverizing blade 32 made of the corresponding recess, (S30) of discriminating whether the waste water is pulverized to have the same size through a water supply line (33) composed of weft and warp fabrics and feeding back the waste water that has not passed through the water line to the pulverization step (S30) A waste water liquor is stacked on the melting furnace 41 of the molten part 40 and the waste water solution stacked by the rotation of the feed screw 42 having the thread provided in the melting furnace is directed toward the discharge nozzle 50 (S50) in which the waste paper is melted by the heat generated by the heater (43) provided in the shaft hollow of the feed screw (42) in the process of being fed and fed, A discharge step S60 of discharging the waste water pushed by the discharge nozzle 50 through the discharge nozzle 50, and a cutting step S70 of cutting the discharged waste paper pellet to form a pellet.

Meanwhile, the melting step (S50) is characterized in that the temperature of the heater is maintained at 90 to 300 DEG C to melt the waste resin in a semi-molten state.

According to the present invention having the above-described constitution, the heating temperature of the heater has to be maintained at a maximum of 350 to 500 ° C or more in order to completely melt the waste resin. However, since the present invention half-melts the waste resin at 90 to 300 ° C In addition to reducing the operating ratio of the heater compared to the conventional one and reducing the load applied to the extruder because the semi-molten waste water has a lower viscosity than that of the completely melted waste paper, it not only increases the durability and life of the extruder, By half-melting, it is possible to produce a resin having a high regeneration rate at a low cost, a decrease in physical properties of the material, and a high quality of a product.

Further, it is not necessary to provide a separate cooling device by simply allowing the resin discharged in the semi-fusion state to be cooled to the natural temperature without using a separate cooling device, and accordingly, And the work force can be minimized and environmental pollutants generated from the operation of the cooling device are not discharged any more, so that it is possible to make a great contribution to the natural environment.

In addition, by forming a single device on a single space by a crushing device for crushing the waste paper as an object to be processed, a crushing device for crushing the crushed waste resin into smaller particles, and an extruding device for compressing the crushed waste resin in a uniform form , It is possible to arrange the compacting apparatus in a narrow and narrow place to be disposed easily. Since the discharger directly discharges the waste paper by first squeezing and discharging it, the volume of the waste paper is reduced and the waste paper is packaged in proportion to the volume of the waste paper being reduced. The amount of the flammable plastic bag to be used is reduced.

In addition, by combining the vibration generating means and the vibration generating means for each device so as to suppress vibration generated when the crushing device provided in the compression bonding device rotates, vibration generated when the crushing device rotates, and vibration generated when the compression bonding device rotates, The durability and service life of the compression bonding apparatus can be increased and noise can be minimized.

Particularly, since the roller shaft of the crushing roller is separated from the cutting blade by the simple bolt connection, the crushing device provided in the crushing treatment device can easily remove the fragments of the waste paper that is caught in the crushing part when the waste paper is broken And it is easy to wash the water, so that the user can use the integral compressor neatly.

In addition, the recycling extruder is provided with a crushing device and a crushing device integrally, thereby maximizing the working efficiency and reducing the processing cost The present invention relates to a semi-molten compressor capable of contributing to a natural environment and a method of processing a combustible wastepaper using the same.

Recently, because of its convenient and convenient handling in various places such as home, office, business, factory, public institution, etc., emissions of wastewater and waste plastics are rapidly increasing due to the utilization of products made of combustible resin .

In this way, the discharged waste water is melted by an extruder which generates high-temperature heat in a recycling processing company, and is molded into a mold and recycled as a new product. First, to explain the process of regenerating the conventional waste water, the waste water recovered by the waste collector is collected by the environmental cleaner, and the waste water collected is sorted according to the kind. The separated wastewater is charged into a crushing apparatus to be crushed, and the crushed waste paper is put into the crushing apparatus again to crush a very small volume. When the pulverized wastepaper is put into the melting apparatus, the screw shaft rotates, the finely pulverized wastewater is rotated by the blade of the screw shaft and mixed with each other. At this time, high temperature heat is generated in the heater provided in the extruder, I am angry.

In the input part of the integrated melting compressor in which the crushing device, the crushing device and the melting device are integrated, The waste water falling to the crushing section and reaching the rotating crushing section of the two crushing rollers is crushed and crushed by the rotational force of the crushing roller and the crushed waste water falls back to the crushing section again, The pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulverized pulver

On the other hand, it is preferable that the particles of the waste paper are crushed to a size smaller than the weft and the width of the sieve. When the particle size of the waste paper is larger than the width of the sieve paper during the initial crushing, The waste water that has been pulverized to a size smaller than the width is discharged through the sieve, and the other waste water is re-pulverized again by the rotating roller, and the re-pulverizing operation is performed until the entrance size becomes smaller than the width of the sieve and discharged.

The pressurizing step S40 and the melting step S50 are carried out in such a manner that the waste paper dropped through the discriminating step S30 is transferred to the inside of the melting furnace of the molten part, And is conveyed in the direction of the discharge nozzle provided in the front portion of the melting compressor.

At this time, the heater provided on the axis of the conveying screw heats up to about 250 to 350 캜, raises the internal temperature of the melting furnace, and the waste water which is being conveyed by the conveying screw is half-melted. Generally, the melting point of the resin is about 90 to 300 ° C, and the resin is heated to about 350 to 500 ° C to completely melt the resin. The resin melted at such a high temperature causes a problem that has a great influence on the change of physical properties. However, since the resin that is half-melted at 90 to 300 ° C does not affect the physical properties, it can produce a superior quality product that retains its inherent properties during reproduction.

In the discharging step S60, the semi-molten waste resin is discharged to the discharging nozzle by pressure feeding of the conveying screw. The semi-molten waste water is formed into a round bar shape by the internal shape of the nozzle portion and discharged. The semi-molten waste discharged through the discharge nozzle is naturally cooled through the nozzle portion. For example, PP vinyl has a melting point of 120 to 150 ° C, PE has a melting point of 90 to 110 ° C, and PET has a melting point of 220 to 240 ° C. Since the current temperature of the semi-molten waste paper is different due to the different melting point as described above, the time for natural cooling of the semi-molten waste paper passing through the nozzle part should be proportional to the temperature of the semi-molten waste paper. For this reason, several nozzles are provided in different lengths, and the temperature of the waste water is naturally cooled by changing the temperature according to the temperature of the waste paper. For example, in the case of PP vinyl, the discharge time of the waste paper is adjusted to 5 seconds using a discharge nozzle having a length of 20 cm, and the discharging time of the waste paper is adjusted to 12 seconds by replacing with a discharge nozzle having a length of 50 cm for PET, And to control the time of natural cooling according to the discharge time.

The cutting operation (S70) is to cut the naturally cooled wastewater into a predetermined size through a rotary cutter to provide the wastewater in the form of a solid fuel product (SRF).

As described above, the waste water extrusion method using a semi-molten resin molding compressor includes a crushing step (S10), a crushing step (S20), a discriminating step (S30), a pressing step (S40) And the cutting step (S70); and the effect derived by the present extrusion method is that, in order to completely melt the waste resin, the heating temperature of the heater But the present invention can reduce the operation ratio of the heater compared to the conventional method because the waste resin is semi-melted at a maximum of 90 to 300 ° C. and the semi-molten waste water is more viscous than the completely melted waste water The load applied to the extruder is reduced to increase the durability and life of the extruder. Particularly, since the waste resin is semi-melted, the regeneration rate can be increased even at a low cost, the change in the material property of the material can be reduced, To It is not necessary to provide a separate cooling device by simply allowing the resin discharged in the semi-fusion state to be cooled to the natural temperature without using a separate cooling device, The operation cost and the work force can be minimized and the environmental pollutants generated by the operation of the cooling device are not discharged any more, so that it is possible to make a great contribution to the natural environment. In addition, by forming a single device on a single space by a crushing device for crushing the waste paper as an object to be processed, a crushing device for crushing the crushed waste resin into smaller particles, and an extruding device for compressing the crushed waste resin in a uniform form , It is possible to arrange the compacting apparatus in a narrow and narrow place to be disposed easily. Since the discharger directly discharges the waste paper by first squeezing and discharging it, the volume of the waste paper is reduced and the waste paper is packaged in proportion to the volume of the waste paper being reduced. The amount of the flammable plastic bag to be used is reduced, and the vibration generated when the crushing device provided in the compression bonding device rotates, the vibration generated when the crushing device rotates, and the vibration generated when the compression device is rotated can be suppressed. By combining the cushioning means with the star, it is possible to increase the durability and lifespan of the crimping apparatus, There is an effect that can be. Particularly, since the roller shaft of the crushing roller is separated from the cutting blade by the simple bolt connection, the crushing device provided in the crushing treatment device can easily remove the fragments of the waste paper that is caught in the crushing part when the waste paper is broken And it is easy to wash the water, so that the user can use the integral compressor neatly.
