Description

A system for manufacturing a biodegradable raw material pellet-type workpiece of a film and a moisture-proof method using a moisture-proof coating device for a pellet-type workpiece obtained therefrom TECHNICAL FIELD [0002] products gained therefrom}

The present invention relates to a system for manufacturing a biodegradable raw material pellet-type workpiece of a film and a moisture-proof method using a moisture-proof coating device for a pellet-type workpiece obtained therefrom, and more particularly, used for crop cultivation or crop cultivation house It relates to a moisture-proof method for realizing moisture absorption prevention through a coating treatment of a coating device for a pellet-type workpiece obtained from such a system together with a system for manufacturing a pellet-type workpiece of a biodegradable raw material of the film to be used.

In general, in the case of conventional mulching films used for crop cultivation or crop growing houses, most of them consist of polyethylene components such as LDPE and HDPE. Not only is it difficult to remove, but it can also cause serious contamination of farmland.

For these reasons, an eco-friendly mulching film that can be naturally decomposed has been developed and distributed, and such an eco-friendly mulching film is based on a biodegradable raw material.

However, since biodegradable raw materials have a property of absorbing moisture contained in the surrounding air due to the characteristics of biodegradable raw materials in the process of being stored for a long period of time, a phenomenon of moisture permeation into the interior of biodegradable raw materials appears, resulting in biodegradable raw materials transformation will occur.

In addition, as the raw material itself is reduced to a food supply source for microorganisms or pests due to the deterioration of these biodegradable raw materials, there is also a problem in that microorganisms or pests reproduce more vigorously.

Biodegradable raw materials, which are raw materials for films used for growing crops or for crop growing houses, must be stored for a long period of time until they are made into films. Double or triple sealed packaging of raw materials is being carried out, and sealed packaged raw materials must be stored in a special storage area with a dehumidifying facility or in a storage tank.

As such, conventionally, as a method to prevent moisture absorption in the process of storing biodegradable raw materials for a long period of time before they are made into films, double or triple sealed packaging work is required, and furthermore, dehumidification work through a separate dehumidification facility Also, the difficulty of workability required for storage and management of biodegradable raw materials and the increase in the required time and cost have always been pointed out as problems.

In particular, as equipment to be built as a dehumidification facility, for example, dry facilities are required, and since these dry facilities are traded at a very high price, the cost required for storage of biodegradable raw materials is inevitably increased. In addition to this, even in the distribution process of biodegradable raw materials, even the packaging box, which should be provided as a means to prevent damage and moisture of the raw material, has to use a waterproof packaging box, so the cost and time are inevitably increased.

In addition, the scope of the present invention is not limited to the embodiments, but should be interpreted based on the technical idea throughout the specification in consideration of various other modifications and implementations.

Hereinafter, with reference to the accompanying drawings, a system for manufacturing a biodegradable raw material pellet-type workpiece of a film according to an embodiment of the present invention and a moisture-proof method using a moisture-proof coating device for a pellet-type workpiece obtained therefrom in detail will be explained

Biodegradable raw materials are mixed with material components extracted from, for example, corn, PLA (poly lactic acid), PBS (Poly butylene succinate), PBAT (Polybutylene adipate-co-terephthalate), inorganic compounds, etc. It may be composed, but biodegradable raw materials do not need to be limited to these material components, and other material components that are naturally degradable may also be included. These biodegradable raw materials are used as biofilms to replace PET.

First, a system for manufacturing a biodegradable raw material pellet-type workpiece of a film according to an embodiment of the present invention, as shown in FIGS. 1 and 2, a conveyor 100, a compressor 200, an extruder 300 , a filter unit 400 , a pellet device 500 , a dehydration device 600 , and a dryer 700 . The components configured in each of the conveyor 100, the compressor 200, the extruder 300, the filter unit 400, the pellet device 500, the dewatering device 600, and the dryer 700 are detailed It should be noted that it is not shown in separate detailed drawings in a relationship that can be fully understood through the description.

The biodegradable raw material may pass through, for example, a fluid such as a melt in the section from the conveyor 100 to the filter unit 400, and may be pelletized in a solid state in the process of passing through the pellet device 500. there will be

The conveyor 100 may be installed in a structure suitable for the purpose of transporting the biodegradable raw material to the compressor 200 , and the compressor 200 is used for compressing the biodegradable raw material transferred from the conveyor 100 . am.

The extruder 300 may be installed in a structure suitable for the purpose of extruding the biodegradable raw material provided from the compressor to the filter unit 400, for example, it is installed in a horizontal structure and is biodegradable by rotation of a screw using the power of a motor. The raw material may be extruded in the direction of the filter unit 400 .

It may be noted that the detailed configuration of the structure of the filter unit 400 is not shown in the drawings as it can be fully understood through the description. The filter unit 400 includes a rectangular block-type body having a plurality of filters slid left or right inside, and a power unit installed on an outer side of the body to provide power necessary for the sliding operation of the plurality of filters. can be configured.

The plurality of filters is configured to be installed in two through-holes of the slide rod that slides left or right, and can be slid left or right at the same time when the slide rod slides. Of course, the slide rod is installed in a structure in which a horizontal sliding operation is possible in the left or right direction of the body in the inside of the body.

The power unit may utilize, for example, a cylinder means to provide power required for the horizontal slide operation of the slide rod, but is not limited thereto, and may include all means capable of horizontal power.

Therefore, the slide rod is connected to the piston of the cylinder and can be slid left or right. (異物, extraneous materials) for discharge and filter replacement. Of course, such a filter may be configured as a filter having a double or triple structure.

The pellet device 500 is installed at the very rear of the filter unit 400 to transform the biodegradable raw material filtered from the filter unit 400 into solid pelletization.

It can be referred to that the detailed configuration of the structure for the pellet apparatus 500 is not shown in the drawings in a relationship that can be fully understood through the description. The pellet device 500 may be composed of a cooling water supply tank, a dibore, a blade installed on the surface of the rear surface of the dibore, a centrifugal separator, and a heat exchanger.

The blade may be installed, for example, in a rotatable structure on the rear surface of the diver, the centrifuge may be installed, for example, at a lower position of the blade, and the heat exchanger may be installed, for example, between the centrifuge and the coolant supply tank. can be installed.

The diver is, for example, a relationship that can be composed of a plurality of circularly arranged through holes so that melts of biodegradable raw materials can be branched into several strands and passed through, so that foreign substances are caught and the filter unit ( 400) filtered biodegradable raw material melts may branch and pass into several strands in the process of passing through the through holes of the dibore, and at the same time as passing through the dibore, the blade is rotated and the die Multiple strands of melt passing continuously through the bore can be cut at a set rotational speed.

The melts cut in this way fall into a centrifuge containing cooling water and can be collected as pellet-type solids while being centrifuged, and the cooling water is a refrigerant fluid for solidifying the melts into pellet-type solids by exchanging heat with the melts. It loses its function and is in a state of process water. The process water is cooled in the process of passing through the heat exchanger while being injected into the connection pipes and supplied to the cooling water supply tank to be reused as cooling water for cooling the melts again.

The dewatering device 600 may perform a function of removing moisture or moisture contained in the pellet-type solids that have passed through the filter unit 400 , and the pellet-type solids that have passed through the dewatering device 600 . Silver may be obtained as a pellet-type workpiece dried while passing through the dryer 700 .

The pellet-type workpiece thus obtained may be stored in a separate storage tank, but since it has a property of absorbing moisture during storage, it is directly put into the coating device 800 and stored in a coated state.

The coating device 800 has a vertical structure, for example, an elevator 810 for lifting and transporting the pellet-type workpiece input through a hopper 810a or an inlet to the upper part, and the upper part of the elevator and the pipe A first coating part 820 for primary coating a pellet-type workpiece that is connected and falling into a structure, a second coating part 830 for secondary coating of a pellet-type workpiece by being installed in a horizontal structure at the lower end of the first coating part, secondary It may consist of a configuration including a silo 900 for long-term storage of the pellet-type workpiece with drying for the coated pellet-type workpiece. Of course, the pellet-type workpiece stored for a long time in the silo 900 may be used as a raw material for later film production without any moisture absorption.

Of course, the first coating part 820 may be further provided in a structure in which a control panel C required for operation of the coating device 800 is installed, and a coating agent is provided on the lower portion of the second coating part 830 . A chemical tank (ST) made of stainless steel for supplying the pellet-type workpiece for spraying while temporarily storing, a pump (P) for controlling the supply amount of the coating agent for supplying the coating agent for spraying, and the pellet The auger gear motor (M) that provides rotational power of the auger necessary for uniform mixing of the workpiece and the coating agent may be further provided in a structure in which the auger gear motor (M) is arranged and installed.

The components (components) configured in each of the elevator 810, the first coating part 820, and the second coating part 830 are in a relationship that can be fully understood through the detailed description, in separate detailed drawings. Note that it is not shown.

The first coating part 820 is on the surface of the pellet-type workpiece under the rotation of the high-speed centrifugal disk together with the spraying of the first coating agent through the centrifugal disk motor in the process of the pellet-type workpiece being lifted and transported from the elevator 810 is falling. It is to perform a coating process to form a coating film of a method of attaching a coating film.

The pellet-type workpiece coated in this way enters the second coating part 830. In this process, the second coating part 830 rotates the auger composed of a mixing blade made of a rubber pan material and a cylindrical tube-type auger shaft. The secondary coating treatment is performed through the even application of the second coating agent to the pellet-type workpiece. Of course, the mixing blades made of these rubber pans and the cylindrical tube-type auger shaft are suitable structures to reduce damage to the pellet-type workpiece.

Of course, it is not necessary to be limited to the high-speed centrifugal disk configured in the first coating part 820 and the auger configured in the second coating part 830, and any means suitable for coating may be included. The means may be, for example, a jet engine required for jet high-pressure jetting of the coating agent, and a jet engine connected to the jet engine and provided with a plurality of high-pressure jet nozzles for jet high-pressure jetting of the coating agent may be used instead.

Furthermore, the injector may, for example, be configured to further include a pressure sensor for detecting the amount and pressure of the first and second coating agents, and a position sensor for detecting the spraying direction for the first and second coating agents, The supply tank for storing the first and second coating agents may be configured to further include, for example, a water level sensor for detecting the storage water level of the first and second coating agents.

In particular, the pressure sensor detects the injection amount and pressure for the first and second coating agents having an excess or less than the set value range of the injection amount and pressure, for example, the first, 2 When the injection amount and pressure of the coating agent are detected, it is determined that there is an abnormality, and as the detection signal sensed from the pressure sensor is transmitted to the central processing unit, the central processing unit quickly analyzes the detection signal to generate power The injection amount and pressure for the first and second coating agents can be returned to the normal track in a state in which an error occurring in the system or the nozzle system of the injector is detected and corrected.

In addition, the position sensor detects the injection direction angle for the first and second coating agents having an excess or less value based on the angle set value range of the injection direction, for example, the first, 2 When the injection direction angle for the coating agent is detected, it is determined that there is an abnormality, and as the detection signal sensed from the position detection sensor is transmitted to the central processing unit, the central processing unit quickly analyzes the detection signal and sprays the injector The direction of spraying for the first and second coating agents can be returned to the normal trajectory in a state in which errors occurring in the direction angle system are identified and corrected.

In addition, the water level sensor detects the water level level of the first and second coating agents having a value less than that of the set value range of the first and second coating agent water levels stored in the supply tank, for example, the water level sensor When the water level for the first and second coating agents is detected from the , 2 It is possible to return the level of the first and second coating agents to the normal track by opening the valve of the supplementary tank connected to the supply tank so that the supply tank can be filled with the coating agent to an appropriate level.

Meanwhile, the pellet-type workpiece coated with the above-described first and second coating agents may form, for example, an inner coating layer, an interfacial layer, and an outer coating layer.

In some cases, the first coating agent, for example, the electrolyte solution and the mixture may be mixed in a weight ratio of 0.5 to 1:1, respectively, and the mixture is a keratin powder material 50 to 60 weight (%), an extract material extracted from lotus leaves 15 to 25 weight (%), 15 to 25 weight (%) of an extract material extracted from taro, and 5 to 10 weight (%) of a colophony material.

Since calcium carbonate is contained in the electrolyte solution, there is an effect of improving the soil through the soil neutralization action of carbonic acid in the process of decomposition of the film. The reason for the high content is to take a phase change coating agent that is different from the existing liquid coating solution. It can act as a major factor in transforming the surface of the processed product obtained through the process into a nanoscale rough raised surface suitable for a superhydrophobic surface structure.

In some cases, the second coating agent may include, for example, an electrolyte solution and a mixture in a weight ratio of 0.5 to 1:1, respectively, and the mixture may include 40 to 50 weight (%) of non-chocolate powder, 35 to colophony material 45% by weight, and 10 to 20% by weight of the keratin powder material.

In particular, the reason why the content of the non-chocolate powder is relatively higher than that of other materials in the second coating agent is that it removes ambient moisture in a way that effectively absorbs moisture that may exist in the vicinity and forms an absorbent coating outer layer with excellent antibacterial properties. am.

Of course, at this time, the colony material serves to form the interfacial layer, and the interfacial layer can block the moisture absorbed through the outer coating layer from flowing into the inner coating layer.

In the method for moisture-proofing such a pellet-type workpiece in the present invention, the pellet-type workpiece is put into the coating device 800 and a one-stop treatment method of the process including the first coating, the second coating, and drying storage It is possible to provide a moisture-proof method capable of obtaining a coated pellet-like workpiece that no longer has a moisture absorption phenomenon.

The moisture-proof method of this pellet-type workpiece is the first coating part 820 of the coating device 800 according to the input of the pellet-type workpiece into the coating device 800 as shown in FIG. 3 with reference to FIGS. 1 and 2 . ) through a) a first coating step, in which the primary coating on the pellet-type workpiece is made, the pellet-type workpiece coated first through the step a) is secondary coated through the second coating unit 830 b) The second coating step, and the step b), the secondary coated pellet-type workpiece is stored in a dried state in the silo (900).

a) First coating step

In step a), as the pellet-type workpiece is fed into the hopper 810a of the coating device 800 and transported up and down through the elevator 810, it is introduced into the first coating part 820, the first coating part In step 820, the first coating is performed in such a way that the first coating agent is attached to the surface of the pellet-type workpiece through a centrifugal disk motor and a high-speed centrifugal disk or sprayer.

The first coating agent may be attached to the pellet-type workpiece in a manner in which particles of a liquid phase are dispersed in a jet high-pressure spraying process in a mixed state of a liquid and a powder, and the sprayer for spraying the first coating agent is a plurality of nozzle types It can be used as an injector having a structure.

In some cases, the first coating agent is, for example, a mixture mixed with an electrolyte solution, and is a mixture composed of a keratin powder material, an extract material extracted from lotus leaves, an extract material extracted from taro, and a colophony material. can be done

The first coating agent is composed of, for example, a mixture of keratin powder material, lotus leaf extract, taro extract, and colophony material. By forming the coating inner layer of the coating layer, it is possible to block the property of the pellet-type workpiece from absorbing surrounding moisture through a moisture-proof action that strongly blocks the inflow of moisture that can be absorbed into the pellet-type workpiece.

At this time, since the keratin powder is the main component of the first coating agent, it is possible to solve the air permeability clogging problem that may be caused by the existing liquid-type coating solution. In other words, keratin powder allows air permeability to the pellet-type workpiece, while also performing the functions of water repellency and waterproofing, so that the active state of the pellet-type workpiece can be maintained. There is no need to perform a separate air injection process for troubleshooting.

As the material of the keratin powder, it will be more preferable to use a material originally processed and extracted from the feathers of birds. In addition, since both the lotus leaf and the taro are plants containing a coating component, it is also preferable that the extracts extracted from the lotus leaf and the taro are mixed with the keratin powder.

b) Second coating step

In step a), when the first coating agent is coated on the pellet-type workpiece, in step b), the first coating agent of the pellet-type workpiece comes from the second coating part 830 of the coating device 800 or through a sprayer. It is a process in which the secondary coating is made in such a way that the second coating agent is applied to the surface to which the is attached.

The second coating agent may be applied to the surface of the first coating agent of the pellet-type workpiece in a manner in which particles of a liquid phase are dispersed in a jet high-pressure spraying process in a mixed state of liquid and powder, and the second coating agent is jet-jetted The injector may be an injector having a multiple nozzle type configuration.

The second coating agent is, for example, a mixture that is mixed with an electrolytic solution, and may be composed of a mixture composed of binchotan powder, colophony material, and keratin powder material.

Since the second coating agent is composed of, for example, a mixture of bonbon powder, colophony material, and keratin powder material, it is to be applied to the portion of the first coating agent applied to the pellet-type workpiece. In this case, as the interfacial layer film and the outer coating layer film having a structure surrounding the coating inner layer film of the coating layer are formed, if there is moisture in the surroundings, the surrounding moisture can be removed in such a way that the outer coating layer film absorbs it, and the inside of the coating outer layer film The interfacial layer film positioned on the may act as a function of preventing the inflow of the moisture.

It is preferable to use the powdered powder obtained from the charcoal of the oak tree which is roasted for 24 to 26 days in a combustion chamber having a temperature range of 1400 to 1500 ° C.

At this time, since the briquette powder is the main component of the second coating agent, it is possible to remove the surrounding moisture in a way that absorbs moisture that may exist in the vicinity. It is made of Quercus phylliraeoides A. Gray and has a carbon content of 93~96%, so it is effective in removing moisture.

In particular, it is preferable that the oak wood and the black oak wood be mixed in a ratio of 6 to 7: 3 to 4 because the individual particles of the binchotan powder are hard and effective in absorbing moisture for a long time. In other words, the absorption period of moisture is short to the extent that individual particles of non-charcoal powder are less rigid.

c) dry storage step

When the second coating agent is coated on the first coating agent portion of the pellet-type workpiece in step b), it can be stored for a long time in a dried state through the silo 900 in step c), and in a coated state The pellet-type workpiece stored in the silo 900 no longer exhibits moisture absorption and can be stored for a long period of time in the silo 900 without deterioration until used as a raw material for film production. The silo 900 may be, for example, a type of dry cabinet equipped with a drying function as well as a storage function.

In this way, the coated pellet-type workpiece can not only prevent decay or deterioration caused by strong moisture blocking, but also, when used as a raw material for a biodegradable film for crop cultivation or crop cultivation house, the As binchotan exhibits superior antibacterial activity, it can also contribute to the growth of crops.

In addition, since the coating agent is formulated in such a way that eco-friendly materials are mixed, a nature-friendly effect of not contaminating the soil in the process of being used as a raw material for a future film can also be expected.
