Description

Wastesynthetic resin emulsifier equipped with air-pneumatic input device}

The present invention relates to a waste resin emulsification device equipped with an air compression injection device, and more specifically, to melting and vaporizing the waste resin during the process of condensing it to produce recycled oil that can be used for heating and power generation. This relates to a waste resin emulsification device equipped with a pneumatic compression injection device for this purpose, and the main technology is the structure of an air compression injection device to reduce the inflow of air when injecting waste resin into the waste resin emulsification device.

Recycling methods for waste resin include material recycling, which involves melting and remolding waste resin, producing solid fuel products (SRF) by melting waste resin and molding it into pellets, and thermal recycling, which is using the solid fuel product (SRF) for power generation or heating. It is classified as chemical recycling, which generates recycled oil by pyrolyzing waste resin, vaporizing it, and condensing it.

In the case of thermal recycling, which is one of the above waste resin recycling methods, dioxins are generated when solid fuel products (SRF) are burned, which causes air pollution, and as a method to complement these problems, recycled oil is produced from waste resin. Chemical recycling is gaining prominence.

Chemical recycling of waste resin is also called emulsification. A technology has been developed to remove chlorine, which causes dioxins, in the process of emulsifying waste resin, so that dioxins are not generated during combustion like solid fuel products (SRF), thus reducing environmental issues. There is an advantage.

Recycled oil produced by emulsifying waste resin has a quality similar to that of kerosene used in boilers, and waste vinyl such as PE, PP, and PS is mainly used as raw materials. The emulsification process for waste resin involves melting, vaporization, and condensation. It is important that oxygen does not enter the facility to prevent combustion of the gas produced by vaporizing the waste resin.

If oxygen is present inside the equipment for emulsifying waste resin, the gas burns and an explosion occurs, which causes a decrease in the production of recycled oil produced, damage to the equipment due to shock, and the risk of fire.

In order to improve the above problems, an example of prior art to reduce the inflow of air when putting waste resin into the emulsification device is Republic of Korea Patent Publication No. 10-1051314, “Vacuum pyrolysis device for waste plastic and vacuum pyrolysis emulsification system using the same.” This is disclosed.

The prior art uses a first cylinder tube in which the input portion has a plurality of permeable holes, a second cylinder tube crossing the first cylinder tube, and first and second cylinders composed of the first and second cylinder tubes. A technology is proposed to reduce the inflow of air when putting waste resin into the hopper.

The above prior art requires improvement in that the space occupied by the device increases by configuring the device in an alternating manner using two cylinders, and that the permeable hole is always open so that external air can be introduced during the input process of waste resin. There are things that can be done.

As an example of other prior art related to the above, Republic of Korea Patent Publication No. 10-1090219 “Organic waste supply device for emulsification device” is disclosed. The above prior art is also a technology to reduce the inflow of air when inputting waste resin into the waste resin emulsification device,

The waste resin is compressed in a primary transfer pipe equipped with a transfer screw as a waste transport supply means, a compression pipe connected to the primary transfer pipe, and a secondary transfer pipe connected to the compression pipe and equipped with a transfer screw as an emulsification means. A technology is proposed to reduce the air flowing into the emulsification means by supplying it, and to reduce the inflow of external air by constructing a rotor supply means on top of the waste transport and supply means.

The above prior art also consists of two transfer screws and a rotor supply means to reduce the air flowing into the emulsification device, so the space occupied by the device increases and the waste resin supplied to the transfer supply means through the rotor supply means is introduced together. There are matters that require improvement in that there is no passage for external air to escape within the transfer and supply means, so that air can flow into the emulsification means.

In addition, the conventional Japanese Patent Application Laid-Open No. 08-12781 (196.05.21.) includes a pusher cylinder (2) and a reciprocating cylinder rod (8, 28) in a hopper, and a gate valve (5, 31). It is provided with, and during the cylinder compression process, a lot of air existing in the space 42 within the pusher cylinder 2 becomes open when the sides 41 and 45 of the pipe are installed and the compression plates 3 and 27 advance. Discloses the configuration of a raw material supply device for thermal decomposition emulsification of air-emitted waste plastic.

However, in the conventional raw material supply device for thermal decomposition emulsification of waste plastic in Japanese Patent Laid-Open No. 08-12781 (196.05.21.), no matter how much waste plastic is put into the hopper and compressed by the pusher cylinder 2, Even if it is compressed strongly and air is expelled through the stool, the waste plastic itself is hard, so a closed space is formed between the finely cut waste plastics, and air is bound to exist in the space between the formed waste plastics. Therefore, the waste plastic compressed in this way is Due to the air existing in the space between them, a certain level of air is bound to be introduced into the emulsification means, so the oxygen in the incoming air combusts the gas and causes an explosion, which causes a decrease in the production of regenerated oil and shock to the equipment. There is a risk of causing damage or fire.

Republic of Korea Patent Publication No. 10-1051314 “Vacuum pyrolysis device for waste plastic and vacuum pyrolysis emulsification system using the same” Republic of Korea Patent Publication No. 10-1090219 “Organic waste supply device for emulsification equipment”

By further minimizing the formation of closed spaces between the devices, the inflow of air exceeding the set level into the emulsification means is prevented, thereby preventing gas combustion and explosion due to oxygen in the incoming air, increasing the production of recycled oil produced and equipment due to shock. Another problem to be solved is to provide a waste resin emulsification device equipped with a pneumatic compression injection device that has a structure that prevents damage and the risk of fire.

The night gate valve 46 is configured horizontally on one side of the case 41, and a cylinder rod 43a1 that performs a linear movement in the horizontal direction on the ground is formed inside the case 41. and a knife (46b) fixed to the cylinder rod (46a1), which has a plate shape and performs the opening and closing function of the inside of the case (41) in a slide manner.

As shown in FIG. 2D, the ash falling through the ash discharge port 12b is loaded on the upper surface of the knife 46b, and when the ash is discharged, the knife 46b moves backwards and the ash loaded on the upper surface of the knife 46b is stored in the space 42b. and the knife (46b) moves forward to prevent external air from flowing into the inner tube (12).

At this time, by maintaining a certain amount of ash loaded in the ash outlet 12b, the inflow of external air when the knife 46b moves backward due to the ash loaded in the ash outlet 12b can be reduced.

In one embodiment, as shown in FIGS. 3A and 3E, the heat generating means has shafts 51x and 52x installed on the wall of the branch injection pipe 21b to provide a gap through which the injected waste resin can pass. A pair of rotating rollers are arranged in parallel with each other and can rotate in opposite directions, each having built-in heating heaters 51h and 52h for heating the waste resin introduced into the branch injection pipe 21b. 51, 52); And a heating coil 53 installed on the outer surface of the branch injection pipe 21b. The pair of rotating rollers (51, 52) each have built-in heating heaters (51h, 52h), are arranged parallel to each other at intervals, and rotate in opposite directions, thereby forming a pair of waste resins that are injected into the branch injection pipe (21b). As it passes through the gap between the rotating rollers 51 and 52, it is primarily heated and becomes soft, and the waste resin that is primarily heated and becomes soft falls and falls on the inner wall of the branch injection pipe (21b). When the waste plastic is secondarily heated by the heating coil 53, it becomes more soft, and when the waste plastic is compressed, the formation of closed spaces between the compressed waste plastics is minimized so that air above the set level is not introduced into the emulsification means. By preventing gas combustion and explosion caused by oxygen in the incoming air, it is possible to increase the production of recycled oil produced and prevent damage to equipment due to shock and the risk of fire.

In another embodiment, as shown in FIGS. 3E and 3F, the rotating roller 51 of the pair of rotating rollers 51 and 52 has a plurality of blades 51c disposed at intervals around the outer peripheral surface. It further includes, of the pair of rotating rollers 51 and 52, the rotating roller 52 further includes a plurality of blades 52c disposed at intervals around the outer peripheral surface, a plurality of blades 51c and a plurality of blades 51c. The blades 52c are arranged adjacent to each other in the shape of double-edged scissors and serve to cut the waste resin passing through the gap between the pair of rotating rollers 51 and 52 into smaller pieces. According to this, the waste resin introduced through the inlet (21in) can be cut more finely by the plurality of blades 51c and 52c adjacent to each other while passing through the gap between the pair of rotating rollers 51 and 52. Accordingly, the heating time is shortened when it is heated by the heating heaters 51h and 52h while passing through the gap between the pair of rotating rollers 51 and 52 and then heated to a soft state by the heating coil 53. It can be.

In another embodiment, the branch injection pipe 21b further includes a plurality of protrusions 21b1 with a semicircular cross-section formed to protrude from the inner wall surface. In this way, a plurality of protrusions 21b1 are formed to protrude from the inner wall surface of the branch injection pipe 21b, so that the waste resin that is primarily heated and becomes soft may fall and fall on the inner wall surface of the branch injection pipe 21b. It is possible to delay the time until the waste resin enters the input pipe main body 21a by preventing relatively rapid entry into the input pipe main body 21a due to the inclination of the branch injection pipe 21b itself, and accordingly, heating coil By increasing the heating time of the waste resin by (53), it becomes possible to make the waste resin more soft.

In a further embodiment, the heating means may include a pair of rotating rollers 51, 52 and a heating coil 53, or a pair of rotating rollers 51, 52 and a heating coil 53. In addition to the configuration of a plurality of protrusions with a semicircular cross-section, a heating device 60 is installed at intervals above the conveyor 200 and heats the waste resin supplied by being placed on the conveyor belt 220 of the conveyor 200 so that it becomes soft. It further includes.

Figure 5 is a state of use according to another embodiment of the air compression injection device 20 presented by the present invention, and Example 2 is a side vent hole 21c and a cover on the outer peripheral surface of the injection pipe 21 in the configuration of Example 1. It is the same as Example 1 except that (21d) is further formed.

As shown in Figure 5, the injection pipe main body 21a has a plurality of side vents 21c through which air can pass are formed on the outer peripheral surface at regular intervals, and is connected to one end of the side vent 21c with a hinge H. A side cover 21d that opens and closes the side vent 21c can be formed.

When the night gate valve (24) is closed and the waste resin is injected into the input pipe (21) and the pressing plate (23) descends to compress the waste resin, the air pressure of the air located in the gap between the waste resins increases and the pressing plate (23) Air is discharged through the ventilation hole 23a of 23).

At this time, the air in the pores located at the bottom, center, or side of the waste resin may be blocked by the waste resin located between the vent holes 23a of the pressing plate 23 located at the top, making it difficult to discharge through the vent hole 23a.

Therefore, with the configuration of Example 2 as described above, the air located in the gap between the waste resins, which did not escape through the ventilation hole 23a of the compression plate 23, is allowed to escape through the side ventilation hole 21c, and the air compression of Example 1 is performed. It is possible to remove air from the waste resin pores more effectively using the input device 20.

In addition, the cover 21d is opened by the pressure of the air when the air located in the gap between the waste resins escapes through the side vent, and after the air escapes, the cover 21d is opened by the load of the cover 21d itself through the side vent 23c. ) is closed to prevent external air from flowing into the input pipe (21).

The waste resin injected into the air compression device 20 may be made of vinyl, and the air in the pores formed between the vinyl forms a sealed state when surrounded by vinyl, making it difficult for the air to escape smoothly. Therefore, in order to solve the above problem, the air compression injection device 20 can be configured as follows.

6A or 6B, the air compression injection device 20 is formed with a plurality of needles 23c and a stopper block 24d disposed at regular intervals at the lower part of the compression plate 23, and the compression plate 23 ) a plurality of shafts 25 that penetrate and couple; and a pusher 26 formed with a plurality of needle holes 26a through which the needle 23c can pass through a circular plate attached to the lower end of the shaft 25. ; and a spring 27 formed on the outer peripheral surface of the shaft 25.

As shown in Figure 6a, when the pressure plate 23 is lowered, before the pusher 26 comes into contact with the waste resin P, it is positioned lower than the needle 23a due to the elastic force of the spring 27 and the load of the pusher 26. A stopper 25a is formed on the upper portion of the shaft 25 to prevent the pusher 26 and the shaft 25 from being separated from the pressing plate 23.

As shown in Figure 6b, when the pressing plate 23 of Figure 6a is further lowered and the pusher 26 comes into contact with the waste resin (P), the pusher 26 is pushed up by the waste resin (P) and the needle 23c. By passing through this needle hole (26a) and penetrating the waste resin (P), a hole is created through which the air located in the gap between the waste resins (P) can escape, making it possible to more effectively remove air from the waste resin (P).

Additionally, if the plurality of needles 23c penetrate the compressed waste resin in a soft state, air can be extracted by piercing any remaining closed space.

At this time, since the lifespan of the spring 27 is shortened when compressed more than the allowable compression length, a stopper block 23d is formed at the bottom of the compression plate 23 so that when the pusher 26 rises, it contacts the bottom of the stopper block 23d. The upper surface of the pusher (26) is in contact to prevent the spring (27) from being excessively compressed and damaged.

After the waste resin (P) is compressed and the air in the void is removed, when the pressing plate 23 rises, the pusher 26 moves away from the pressing plate 23 due to the elastic force of the spring 27, as shown in Figure 6a. It returns to its original state, and the pusher 26 pushes out the waste resin (P) that has penetrated the needle (23c), preventing the waste resin (P) from coming up with the needle (23c).

The above configuration is capable of effectively removing the air located in the gap between the waste resin (P) compared to Example 1, but there is a limit to setting the length of the needle (23c), so when the device is operated, the needle (23c) is used to remove the waste resin (P). It is desirable to add an amount that can evenly penetrate P) and increase the number of operations per hour compared to Example 1.

The present invention described above has been described with reference to an embodiment shown in the drawings, but this is merely illustrative, and various modifications and other equivalent embodiments can be made by those skilled in the art. should be clarified. Therefore, the true technical protection scope of the present invention should be interpreted in accordance with the attached claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
