Description

Device to separate objects by vibration}

The present invention relates to a vibration separating device, and more particularly, to be configured to be suitable for use when separating the mixture of plastic pulverized and water from each other in the waste plastic recycling system or when separating other solid-liquid substances into solid and liquid. .

As is well known, a number of devices have been developed to separate these solid-liquid substances into solids and liquids when they are discharged in a mixture of solids and liquids, and most of these devices fix screens with numerous arrangements of fine vent holes. When the high-molecular substance is introduced onto the screen while the vibration motor is fixed to the lower surface of the case, the liquid substance of the high-liquid substance is released through the discharge hole of the screen by the vibration of the vibration motor and is discharged through a separate discharge line. And, the solid material is configured to be discharged through a discharge line different from the liquid material discharge line by moving by the vibration of the vibration motor in a state in which the liquid material is separated.

Among these solid-liquid separators, a vibration-flow multistage sorter disclosed in Japanese Patent Laid-Open No. 2000-12286 will be described as an example of a conventional solid-liquid separator.

Vibration-flow type multi-stage sorter according to the Patent Publication No. 2000-12286, the casing of the cylindrical through which the upper and lower passage; A porous plate fixed to the inside of the lower side of the casing; A screen fixed to the inside of the casing at a predetermined interval on the upper surface of the porous plate; A plurality of silicon balls loaded movably in the space between the porous plate and the screen; A filter medium comprising a discharge port formed through one side of the upper casing of the screen through the casing: The upper part is connected to the lower part of the filter body, trapping the liquid material passing through the filter medium is trapped: the bottom of the trap It is connected to be fixed to the vibration means for vibrating the filter medium and the trap;

The filter mediums of different screen meshes are continuously connected vertically. When a solid liquid substance flows into the uppermost screen through the upper casing, the solid substance is changed from the uppermost screen to the particle size by the vibration of the vibrating means. Filtering is performed in turn, and solid materials with different particle diameters are discharged through the outlets connected to the respective screens, and the liquid substance exiting the lowermost part can be discharged through the trap. It can be prevented by the vibration of the silicon ball interposed between and the porous plate.

However, the vibration-flow multi-stage sorter according to this Patent Publication No. 2000-12286 has a cylindrical shape, and the screen is horizontal, so that the solid material placed on the screen after the liquid material is separated by vibrating means. It is a structure that discharges only when it meets with the discharge port while moving around by vibration, and the separation time between the solid and liquid materials is very delayed, and the gap between the screen and the porous plate is not defined. If the particle diameter of the ball is smaller than the distance between the screen and the porous plate, the elastic force of the silicon ball itself and the vibration of the vibrating means work together, which may cause the silicon ball to move excessively between the screen and the porous plate. Excessively vibrated and the object When the solid-liquid separation can be scattered, as well as that was a disadvantage that can cause a loud noise.

In addition, since there is a direct connection between the filter medium and the base frame supporting it, when the filter medium vibrates by vibrating means, the vibration is transmitted to the base frame as it is, causing a continuous load on the device and adversely affecting the health of the worker. There was a downside.

On the other hand, plastic is mainly made of unsaturated polyester (PET) such as PET bottles used for beverage bottles containing cola or cider, PE, PP, HDPE containers which are non-edible household goods containers, and PE, PP, HDPE, etc. Containers, etc., are being recycled through recycling plants due to the establishment of a resource recycling policy.

Among these plastics, those having a lower specific gravity than water are mainly collected and recycled through a separation process by specific gravity after crushing, which will be briefly described.

First, in the process of crushing the collected plastic through a pulverizer, mechanical grinding is performed using a rotary blade, and in this process, water is cleaned to improve crushing efficiency while cleaning foreign substances such as sand, cement, and soil on the waste plastic. As such, the waste plastics pulverized from the pulverizer are transferred to the treatment tank together with the water.

In the treatment tank, materials such as sludge that is heavier than water, water, and recycled plastic pulverized products having a lower specific gravity than water form a sequential layer according to the difference in specific gravity, and the uppermost plastic pulverized material is transferred to the dehydrator side. It is recycled after dehydration, and the sludge and water at the bottom of the remaining treatment tank are discharged to the outside to collect sludge through a bag made by weaving synthetic resin film and discarded, and all the drained water and the dehydrated water through the dehydrator are used as underground reservoir tanks. The water in the underground reservoir tanks is returned to the grinder.

However, the water flowing into the reservoir tank must contain various substances, and if the sediment is continuously accumulated in the reservoir tank, the water capacity has to be reduced gradually. The sediment treatment was very cumbersome and costly, and the water located in the middle by the three-layer structure inside the reservoir tank blocked the surface and was unable to supply oxygen. As a result, the large amount of water must be covered by the water supply, so in some cases, the company could be abandoned because it could not afford the water price.In order to secure low capacity, several large storage tanks were provided at the bottom of the plastic recycling plant. Equipment costly Viscosity is possible.

Therefore, it is desirable to apply a new system that does not introduce wastewater generated in the waste plastic recycling process into the underground storage tank and filters only the foreign matter from the wastewater and then puts it back into the grinder. There is a need for a device that separates solid foreign matter and liquid water from the generated wastewater.

The present invention has been proposed in view of this point, and when a solid-liquid mixture is introduced, it is possible to separate each material within a faster time when separating it into a solid material and a liquid material, as well as a vibration that can increase the separation efficiency. It is to provide a separation device.

In another aspect, when applied to the waste plastics regeneration process, it is possible to reduce the water consumption as well as to reduce the regeneration cost by providing a mediating role to directly return the waste water to the grinder without introducing the waste water into the underground storage tank. It is to reduce the equipment cost by allowing the waste plastic to be smoothly recycled without the water tank.

In order to solve this problem, the present invention consists of a rectangular container shape opened only in the upward direction, and fixed to one end and the other end of the narrow portion so that the input plate and the discharge plate extend outward, respectively, the input plate and the vessel A side plate further extending upward in a publishing position, and one side of the bottom surface is fixed to the base frame at an inclined angle in a discharge direction with a drain pipe connected thereto;

A separating plate detachably fixed to an intermediate portion of the case so as to be horizontal with the input plate and the discharge plate in a state where a plurality of separation holes of a predetermined diameter are drilled;

It is thicker than the separation plate and is fixed at a wider interval than at least the diameter of the drain hole between the separation plate and the lower surface of the case in a state in which a plurality of drain holes having a larger diameter than the separation hole are drilled. The intermediate plate is formed with a plurality of partitions;

A plurality of silicon balls configured to have a diameter equal to a distance between the separating plate and the intermediate plate, the silicon balls being equally numbered for each partition of the intermediate plate between the separating plate and the intermediate plate;

It is characterized in that the vibration motor is fixed to the lower surface of the case to generate vibration.

Also optionally, a plurality of compression coil springs may be interposed between the lower surface of the case and the upper surface of the base frame.

According to the present invention, since the case in which the separator is fixed is installed to be inclined in the discharge direction, when a high-liquid substance is put on the input plate of the upper portion, the water falls out through the separation hole while naturally descending to the separator plate by vibration and gravity of the vibration motor. Only the substance can escape to the discharge plate, so that the separation action can be made in a very fast time, and some of the silicon balls interspersed closely between the separator plate and the intermediate plate fall into the drain hole and the vibration of the vibration motor and itself Because it can generate minute vibrations to the extent that it springs up by the elastic force of the elastic force, it can prevent the blockage of the separation hole of the separation plate smoothly, and it doesn't cause the contents to pop out and generate noise during the solid-liquid separation process. There is an advantage that does not, the number equal to each partition of the middle plate Since the silicon ball is accommodated, the entire separator plate can vibrate uniformly, so that the entire separator hole can fully function without clogging, and as a result, the moisture content is very low in the discharged solid material, thereby greatly improving the separation efficiency. Will be.

In addition, since a plurality of compression coil springs are interposed between the case and the base frame, the vibration of the vibration motor is absorbed by the compression coil springs and thus does not affect the base frame, thereby extending the overall life of the device. There is an advantage that can be improved.

In addition, if the vibration separation device is applied to treat wastewater generated during the waste plastic regeneration process, most of the foreign matter having a certain particle size among the wastewater including the foreign matter can be separated and disposed of, and the water is treated through a treatment tank. It can be re-introduced into the pulverizer immediately, thereby improving water recyclability and reducing the use of water supply, thereby reducing production costs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a vibration separating apparatus according to the present invention, Figure 2 is a cross-sectional view of the vibration separating apparatus according to the present invention, Figure 3 is a schematic configuration as an example that the vibration separating apparatus according to the present invention is applied to the waste plastic recycling process It is also.

The present invention is to provide a vibration separation device 100 for transmitting the vibration generated through the vibration motor 150 to the device to separate the solid material into a solid material and a liquid material, to the base frame 101 The case 110 is fixed to the discharge side inclined at a predetermined angle, the lower surface of the case 110 is fixed to the vibration motor 150 is configured to transmit the vibration generated through the vibration motor 150 to the case 110. .

The case 110 is formed in a rectangular container shape which is open only in an upward direction, and the input plate 111 and the discharge plate 112 extend outwardly at one end and the other end of the narrow portion of the case 110. It is fixed so that the liquid-like material is injected into the input plate 111 and is discharged through the discharge plate 112.

In addition, the separating plate 120 in which the minute size of the separation hole 121 is punctured innumerably is detachably fixed to the middle portion of the case 110 so as to be substantially horizontal with the input plate 111 and the discharge plate 112. Since the separator 120 is in continuous contact with moisture, it is preferable to configure the stainless steel material to improve corrosion resistance, and to configure the thickness of about 0.3 mm because it should maintain rigidity while having some elasticity. Each separation hole 121 is configured to about 0.5 mm.

The separation plate 120 is detachably fixed to the middle portion of the case 110 through a fixing member such as a bolt, the replacement of the damaged separation plate 120 or the separation plate of the different diameter of the separation hole 121 Replacement to 120 may be made freely.

In addition, since the input plate 111, the separation plate 120, the discharge plate 112 is approximately horizontal, the position of the input plate 111 and the discharge plate 112 so that the high-liquid substance does not fall to the outside of the case 110. The side plate 113 of the case 110 is upwardly configured to extend further upward, and the drain pipe 114 is connected to one side of the case 110 so that the separated water can escape.

In addition, the intermediate plate 130 is fixed between the separating plate 120 and the lower surface of the case 110, the intermediate plate 130 is configured to a thickness of about 1.5mm to prevent damage, the material is specifically Although not limited, corrosion resistance in a moisture environment is of course fixed to the inner surface of the case 110 by welding, and thus it is preferable that the stainless steel material or the nonferrous metal material is used.

In the intermediate plate 130, a plurality of drain holes 131 having a larger diameter than the separation hole 121 are drilled in a state in which a plurality of drain holes 131 are disposed between the separation plate 120 and the bottom surface of the case 110. The welding is fixed at a wide interval, and the separation plate 120 and the intermediate plate 130 is interposed between a plurality of silicon balls 140 having the same diameter as the gap therebetween.

At this time, since the diameter of the silicon ball 140 is configured to about 25mm, the drain hole 131 is preferably configured to be smaller than about 15mm, the spacing between the separation plate 120 and the intermediate plate 130 is also 25mm It is configured to a degree.

In addition, since the plurality of silicon balls 140 may be driven to one side by the vibration of the vibration motor 150, a plurality of partitions 131 may be formed in the intermediate plate 130 to form the silicon balls 140 for each of the partitions 131. ) In equal numbers.

In addition, a plurality of compression coil springs 160 are interposed between the lower surface of the case 110 and the upper surface of the base frame 101 so that vibration generated through the vibration motor 150 is not transmitted to the base frame 101 side. .

When the high-liquid substance is introduced into the input plate 111 of the upper part of the case 110 in the state configured as described above, the high-liquid substance is naturally lowered by the vibration and gravity of the vibration motor 150 and is formed on the separating plate 120. Only water exits through the myriad of separation holes 121, and the solid material may continue to descend and be discharged to the outside through the discharge plate 112.

In addition, the water dropped through the separation hole 121 may exit the drain hole 131 of the intermediate plate 130 and may be transferred to the other part through the drain pipe 114.

On the other hand, since the solid material has a certain degree of viscosity, the finely formed separation hole 121 may be blocked in the process of separating the solid material. When the vibration motor 150 vibrates, the separation plate 120 and the middle Some of the silicon balls 140 interposed between the plates 130 fall into the drain hole 131 to secure a space that can flow between the separation plate 120 and the intermediate plate 130, and at the same time vibration motor By vibrating the 150 and by the elastic force of the silicon ball 140 itself, it will be able to prevent the phenomenon that the high-liquid material blocks the separation hole 121 because the finely hitting the separation plate 120.

Of course, since the impact of the separation plate of the silicon ball 140 is not made severely, the high-liquid material does not bounce up or generate noise in the separation process.

In addition, since the vibration generated by the vibration motor 150 is absorbed and extinguished by the compression coil spring 160 interposed between the case 110 and the base frame 101, it is natural that the vibration is transmitted to the base frame 101. It can be cut off so that it can extend the life of the machine because it doesn't load the whole device, and it can provide a good environment for workers to work.

3 is a vibration separation device 100 according to the present invention for the treatment of waste water generated in the waste plastic regeneration process consisting of a grinder 10, a treatment tank 20, a dehydrator 30, an air blower 40, and the like. As an example of application, water containing foreign matters from the dehydrator 30 during the regeneration of waste plastics or water containing foreign matters from the treatment tank 20 may be used in the vibration separating apparatus 100 according to the present invention. If the input plate 111 is introduced into the input plate 111, only the water passes through the separation hole 121 of the separation plate 120, and foreign particles having large particles may continue to descend and be discharged to the outside through the discharge plate 112. The fine vibration is added by the silicon ball 140 located between the separation plate 120 and the intermediate plate 130 along with the separation action to separate the foreign matter and water more efficiently.

In addition, the foreign substances discharged to the outside may be disposed separately and disposed of, and the water passing through the separation plate 120 of the vibration separating apparatus 100 according to the present invention is discharged through the drain pipe 114 through the drain hole 131. Since only the supernatant can flow back into the crusher 10 after being introduced into the settling tank 80, the water is collected in the underground water storage tank and recycled to the crusher 10 directly, as in the conventional waste plastic recycling system. It can be used to significantly reduce the amount of water used, as well as the need for a separate water storage tank can be saved.

Of course, the vibration separating apparatus 100 according to the present invention is not applicable only to the waste plastic regeneration system, and the vibration separating apparatus 100 according to the present invention is applied to all processes for separating the solid-liquid mixture into a solid and a liquid. It can be done.
