Description

Sealing device of oil reduction system

[0001] The present invention relates to a sealing device for an oil reduction system, and more particularly, to a sealing device for an oil reduction system that is configured between a decomposition device and a conveying device to provide sealing so as to prevent harmful gases such as oil vapor and water vapor generated during thermal decomposition from being released to the outside, thereby preventing pollution of the working environment and the environment due to leakage of harmful gases.

[0002] In general, plastics are materials that can be formed by heating, pressurizing, or both, or resin products made from such materials. Typically, plastics refer to synthetic resins. While the final product is solid and has a high molecular weight, they possess fluidity during molding, making them easy to mold and produce products of various shapes. Furthermore, since plastics are manufactured into polymers by polymerizing various substances using petroleum as the main raw material, users can polymerize substances with desired properties to produce polymer compounds with diverse functions and properties, and their applications and usage are rapidly increasing. Furthermore, plastics, a type of petroleum compound that uses petroleum as the main raw material, are manufactured into polymers. Therefore, they are difficult to decompose, have excellent corrosion resistance, and can be used for long periods of time. They are easy to mold, allowing for the production of various shapes. Furthermore, their light weight allows them to be used in a variety of applications, from household goods to various industrial products. Consequently, their usage is rapidly increasing.

[0003] However, waste plastic discarded after use has the characteristic of being difficult to decompose, making it difficult to landfill, and when incinerated, various harmful gases are emitted, polluting the atmospheric environment, making it difficult to dispose of waste plastic.

[0004] Additionally, as the reserves of oil, including petroleum, which is the fuel used to produce waste plastic, decrease, the price of oil increases, and as resources are depleted, the need to reuse the oil present in waste plastic is increasing.

[0005] Accordingly, a waste plastic oil reduction system has recently been developed to increase resource recycling by reducing and recovering the oil contained within waste plastic.

[0006] The conventional waste plastic oil reduction system is as shown in Fig. 1.

[0007] A decomposition device (1) that receives waste plastic and heats it to a certain temperature, for example, 300 to 800°C, to thermally decompose it to form a liquid resin, a transport device (2) that is provided on one side of the decomposition device (1) to transport the liquid resin, a purification device (3) that receives the liquid resin transported through the transport device (2) and purifies it to produce oil, and a sealing device (4) is configured between the decomposition device (1) and the transport device (2).

[0008] However, the conventional airtight device (4) is simply configured with a flange structure, and thus does not secure airtightness between the rotating decomposition device (1) and the stationary transport device (2), which causes the harmful gases generated during the thermal decomposition process of waste plastic to leak, thereby polluting the working environment and the atmospheric environment.

[0009] In order to solve the above-mentioned problems, the purpose of the present invention is to provide an airtight device for an oil reduction system that is configured between a decomposition device and a transport device to prevent harmful gases such as oil vapor and water vapor generated during thermal decomposition from being released to the outside, thereby preventing pollution of the working environment and the environment due to leakage of harmful gases.

[0010] In order to achieve the above object, the present invention comprises a decomposition device that heats waste plastic to 300 to 800°C to thermally decompose it to form a liquid resin, and a transport device that is provided on one side of the decomposition device and transports the liquid resin, and a sealing device of an oil reduction system that is provided on the decomposition device and the transport device to support the decomposition device and prevent harmful gases from leaking to the outside, the sealing device comprising: a fixed flange provided on one end of the decomposition device; a first sealing pusher provided on one side of the fixed flange; a sealing packing that is provided on one end of the first sealing pusher and supports the first sealing pusher so that the sealing force is improved by receiving a pressing force provided by the first sealing pusher; a plurality of stop rings that are provided on one side of the sealing packing and are symmetrically provided on each of the two sides; a sealing filler that is provided between the plurality of stop rings and supports the sealing force so that the sealing force is improved; a sealing packing provided on the other end of the stop ring; a second sealing pusher provided on one end of the sealing packing; It is characterized by including: a sealing plate configured at one end of the second sealing pusher; a sealing housing configured in a bifurcated shape to surround the outer circumference of the fixed plate, so that the first sealing pusher, the sealing packing, the stop ring, the airtight filler, and the second sealing pusher can be stably configured between the fixed flanges on the inner side, and the sealing plate is supported so that it is fixed at one end; at least one first adjusting unit configured at one end of the sealing housing, which moves forward or backward in the direction of rotation, thereby supporting the first sealing pusher to press the sealing packing and maintain a sealing force as the first sealing pusher is moved; and at least one second adjusting unit configured at one end of the sealing plate, which moves forward or backward in the direction of rotation, thereby supporting the second sealing pusher to press the sealing packing and maintain a sealing force as the second sealing pusher is moved.

[0011] In the present invention, it is preferable that the first adjusting part includes an adjusting bolt having one end penetrating one side of the sealing housing and fastened to one side of the first sealing pusher to support the first sealing pusher to move forward or backward depending on the rotational direction; and at least one disc spring configured between one end of the adjusting bolt and one side of the sealing housing to absorb an external force applied from the outside and support the first sealing pusher so that the pressing force of the adjusting bolt is maintained.

[0012] In the present invention, it is preferable that the second adjusting part includes: a support housing configured to be fixed to one end of the sealing plate; a second adjusting bolt configured to be fastened to one side of the support housing; a first pressing member configured to be disposed inside the support housing and configured to move forward or backward depending on the rotational direction of the second adjusting bolt; a second pressing member configured to be spaced apart from the first pressing member by a predetermined interval and having the other end pass through the sealing plate to support pressing one side of the second sealing pusher; a compression spring configured between the first and second pressing members to absorb an external force applied from the outside and support such that the pressing force of the second sealing pusher by the second adjusting bolt is maintained; and a sealing ring configured between the sealing plate and the second pressing member to support maintaining airtightness.

[0013] In the present invention, the airtight filler is preferably composed of 60 to 70 parts by weight of nitrobutadiene rubber; 10 to 20 parts by weight of carbon black; 10 to 20 parts by weight of inorganic filler; 1 to 10 parts by weight of zinc oxide; 3 to 5 parts by weight of plasticizer; 1 to 5 parts by weight of antioxidant; and 0.5 to 3 parts by weight of vulcanizing agent.

[0014] According to the present invention, by providing airtightness between a decomposition device and a transport device to prevent harmful gases such as vapor and water vapor generated during thermal decomposition from being released to the outside, there is an effect of preventing pollution of the working environment and the environment due to leakage of harmful gases.

These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined by the description of the claims.

[0029] Meanwhile, the terminology used in this specification is for the purpose of describing embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. As used herein, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, operations, and / or elements to the mentioned components, steps, operations, and / or elements. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030]

[0031] The sealing device (10) of the oil reduction system of the present invention, as shown in FIG. 2, is configured between the decomposition device (1) and the transfer device (2), and provides sealing so as to prevent harmful gases such as oil vapor and water vapor generated during thermal decomposition from being released to the outside, thereby preventing pollution of the working environment and the environment due to leakage of harmful gases.

[0032] The above-mentioned sealing device (10) may include a fixed flange (100), a first sealing pusher (200), a sealing packing (300), a stop ring (400), a sealing filler (500), a second sealing pusher (600), a sealing plate (700), a sealing housing (800), a first adjusting part (910), and a second adjusting part (920), as shown in FIGS. 3 and 4.

[0033] The above fixed flange (100) is configured at one end of the separation device (1) and supports the components of the sealing device (10) so that they can be stably configured.

[0034] The above fixed flange (100) includes a fixed end (110), a support pipe (120), and a through hole (130), as shown in FIG. 5.

[0035] The above fixed end (110) is configured to be fixed to one end of the disassembly device (1). In this case, the fixed end (110) is formed with a plurality of fastening holes into which fastening means, such as bolts, are inserted so that the fixed end can be fixed to the disassembly device (1).

[0036] The above support pipe (120) is formed at one end of the fixed end (110) to a certain length and supports the configuration of the sealing device (10).

[0037] The above support pipe (120) is formed with a settling groove (122) of a certain depth so that a stop ring (400) is settling at each end of the above airtight filler (500) to support the airtight filler (500) positioned at the center.

[0038] In addition, the above-mentioned fixing groove (122) includes a number of fastening holes (124) formed at a certain depth along the circumference so that the stop ring (400) can be firmly fixed to the support pipe (120) by a fastening means.

[0039] The above-mentioned hole (130) is configured to penetrate the center of the fixed end (110) and the support pipe (120), so that one end of the transport device (2) can be inserted.

[0040] The first sealing pusher (200) includes a support member (210), a sealing member (220), and a second hole (230), as shown in FIG. 6.

[0041] The above support member (210) is formed to a certain thickness, and a plurality of second fastening holes (212) are formed so that it can move forward or backward radially depending on the fastening force of the first adjusting member (910).

[0042] The above-mentioned sealing member (220) is configured to protrude from one end of the above-mentioned support member (210) by a certain length, and is supported so that the sealing force is improved by pressing the sealing packing (300) configured at one end of the sealing member (220) while moving by the forward and backward force of the first adjusting member (910).

[0043] The above second hole (230) is formed to penetrate the center of the support member (210) and the contact member (220), so that the support pipe (120) of the fixed flange (110) is inserted.

[0044] The above-described sealing packing (300) is configured between the fixed flange (100) and the sealing housing (800), and is positioned at each end of the sealing filler (500), thereby enhancing the sealing force together with the sealing filler (500). In this case, the sealing packing (300) is formed with a certain thickness, and is configured in multiple numbers to support the sealing force to enhance the sealing force. Accordingly, the multiple sealing packings (300) maintain a firm sealing state by the pressing force of each of the first sealing pusher (200) and the second sealing pusher (600), thereby enhancing the sealing force.

[0045] The above-mentioned tight packing (300) is formed of graphite.

[0046] In addition, the above-mentioned tight packing (300) may include a gasket (310) that supports tight contact with one end of the single-groove (122) of the fixed flange (100).

[0047] That is, by inserting the gasket (310) into one end of the groove (122) of the fixed flange (100) and then sequentially inserting at least one sealing packing (300), the gasket (310) compensates for a gap that may be generated due to the surface roughness of the groove (122), thereby further securing the airtightness of the sealing packing (300).

[0048] The above stop ring (400) is seated in the step groove (122) of the fixed flange (100), so that a sealing filler (500) is formed between the fixed flange (100) and the sealing housing (800).

[0049] As shown in Fig. 7, the above stop ring (400) is formed to penetrate the center, and a third through hole (410) is formed to support the support pipe (120) of the fixed flange (100) so that it can be inserted and seated in the step groove (122) of the support pipe (120).

[0050] In addition, the stop ring (400) includes a plurality of third fastening holes (420) formed to penetrate the third through hole (410) along the circumference.

[0051] Accordingly, the stop ring (400) is fixed in the step groove (122) after the third hole (410) is inserted into the support pipe (120), and then, by inserting a fastening means into a plurality of third fastening holes (420), fastening is performed to the fastening hole (124) of the support pipe (120), thereby maintaining the stop ring (400) firmly fixed to the fixed flange (100). In this case,

[0052] The above-mentioned sealing material (500) is filled between the stop rings (400) fixed on each side of the support pipe (120) to ensure sealing by its gel properties.

[0053] The above-mentioned airtight filler (500) may be composed of 60 to 70 parts by weight of nitrobutadiene rubber, 10 to 20 parts by weight of carbon black, 10 to 20 parts by weight of inorganic filler, 1 to 10 parts by weight of zinc oxide, 3 to 5 parts by weight of plasticizer, 1 to 5 parts by weight of antioxidant, and 0.5 to 3 parts by weight of vulcanizing agent.

[0054] The above nitrobutadiene rubber has an acrylonitrile content of 20 to 50% and has excellent heat resistance and wear resistance.

[0055] Carbon black is used to increase the wear resistance and rigidity of rubber composite materials. If it is less than 10 parts by weight, the hardness of the vulcanized product is low, and if it exceeds 20 parts by weight, the hardness is high, causing problems in workability due to heat generation during mixing.

[0056] Inorganic fillers are used to improve heat resistance and provide lubrication to rubber composite materials, and are formed by mixing silica, talc, and charcoal in a weight ratio of 1:0.5 to 0.7:0.3 to 0.5.

[0057] Zinc oxide is a vulcanization aid added to activate the crosslinking reaction during the vulcanization reaction. This increases the crosslinking speed and prevents side chain reactions, thereby increasing crosslinking density. In this case, if it is less than 1 part by weight, the activation of the crosslinking reaction is minimal, and if it exceeds 10 parts by weight, there is a problem of the mechanical properties of the vulcanized product being reduced due to the zinc oxide remaining without reacting.

[0058] Plasticizers make polymers flexible and improve flowability and cold resistance. If the amount is less than 3 parts by weight, the flowability and cold resistance of the rubber composition are poor. If the amount exceeds 5 parts by weight, the plasticizer may leach and volatilize into the vulcanized product.

[0059] Antioxidants prevent the rubber component from oxidizing. For example, the antioxidant may be a quinoline-based antioxidant.

[0060] A vulcanizing agent chemically bonds the molecular chains of nitrobutadiene rubber when the rubber composition is heated to an appropriate temperature. For example, the vulcanizing agent may be a sulfur-donating vulcanizing agent, such as sulfur, amine disulfide, polymeric polysulfide, or sulfur-olefin adduct.

[0061] Additionally, the sealant may be a heat-resistant grease.

[0062] The second sealing pusher (600) is configured in a direction symmetrical to the first sealing pusher (200), and the sealing force can be improved by pressing the sealing packing (300) configured between the fixed flange (100) and the sealing housing (800). In this case, the second sealing pusher (600) is configured in a ring shape.

[0063] The above sealing plate (700) is configured on one side of the support pipe (120) of the fixed flange (100), and is fixed to one end of the sealing housing (800) described later, thereby supporting the second adjusting unit (920) so that it can be stably configured.

[0064] As shown in FIG. 8, the above sealing plate (700) includes a fourth through hole (710), a fourth fastening hole (720), an insertion hole (730), and a fifth fastening hole (740).

[0065] The above fourth hole (710) is configured to penetrate through the center so that one end of the transport device can be inserted.

[0066] The above fourth fastening holes (720) are formed in a radial shape in multiple numbers so that the sealing plate (700) can be fixed to one end of the sealing housing (800) by a fastening means.

[0067] The above insertion holes (730) are formed in a radial shape in multiple numbers, so that one end of the second adjusting part (920) can be inserted to press the second sealing pusher (600).

[0068] The fifth fastening hole (740) is formed radially around the insertion hole (730) so that one end of the second adjusting part (920) can be fixed to the sealing plate (700).

[0069] The above sealing housing (800) is configured to surround the outer circumference of the support pipe (120) of the above fixed flange (100), thereby improving the sealing force between the above fixed flange (100) and the sealing housing (800), thereby preventing harmful gases from leaking through the hole (130) of the above fixed flange (100). In this case, the above sealing housing (800) is formed in a semi-split shape.

[0070] As shown in FIG. 9, the above sealing housing (800) includes a second fixed end (810), a second support pipe (820), a fifth through hole (830), and a third fixed end (840).

[0071] The second fixed end (810) is formed at each end. In addition, the second fixed end (810) is formed radially with a second insertion hole (812) so that a first adjusting part (910) can be formed at one end, and a sixth fastening hole (814) is formed radially at the other end so that a second adjusting part (920) can be formed.

[0072] The second support pipe (820) is configured between the second fixed ends (810) to have a certain length. In addition, the second support pipe (820) is formed with an injection hole (822) for injecting a composition of a sealing filler from the outside to the inside so that a sealing filler (500) is formed between the fixed flange (100) and the sealing housing (800).

[0073] In addition, an injection nipple or a closing cap is formed in the injection hole (822) to prevent the injected sealing filler from leaking out randomly.

[0074] The above fifth hole (830) is configured in the center of the second fixed end (810) and the second support pipe (820) so that the support pipe (120) of the fixed flange (100) is inserted.

[0075] The third fixed member (840) is configured to protrude from the outer periphery by a certain length, and supports a plurality of sealing housings (800) formed in a semicircular shape so that they can be firmly fixed by a fastening means after being engaged.

[0076] Accordingly, the sealing housing (800) is configured to be fixed or separated by mutual engagement in a semicircular shape, so that when maintenance of the sealing device (10) is required due to long-term use or other reasons, the mutually engaged portion can be disassembled to expose the components formed inside the sealing housing (800) to the outside, thereby facilitating maintenance.

[0077] The above first adjusting part (910) is configured on the fixed end (110) of the fixed flange (100) to provide a pressing force to the airtight packing (300) configured on one side of the inside, thereby improving the sealing force of the airtight packing (300).

[0078] The first adjusting unit (910) includes an adjusting bolt (912) and a plate spring (914), as shown in FIGS. 10 and 11.

[0079] The above adjustment bolt (912) is inserted into the second insertion hole (812) formed on one side of the second fixed end (810) of the sealing housing (800), and the end is fastened to the second fastening hole (212) formed in the support end (210) of the first sealing pusher (200), thereby moving the first sealing pusher (200) forward or backward depending on the rotational direction of the adjustment bolt (912).

[0080] The above-mentioned plate spring (914) is formed in a plate shape and is configured to provide elasticity, and is configured between the adjustment bolt (912) and one side of the second fixed end (810) of the sealing housing (800), thereby providing elasticity to the adjustment bolt (912) and exerting elasticity so that the compressive force of the adjustment bolt (912) is not released due to an impact or vibration applied from inside or outside. In this case, the plate springs (914) are configured to be stacked in a symmetrical manner.

[0081] The above second adjusting part (920) is configured on one end of the second fixed end (810) of the sealing housing (800), and provides a pressing force to the airtight packing (300) configured on the other inner side, thereby improving the sealing force of the airtight packing (300).

[0082] The second adjusting unit (920) includes a support housing (922), a second adjusting bolt (924), a first pressure member (926), and a second pressure member (928), as shown in FIGS. 12 and 13.

[0083] The above support housing (922) is fixed to one end of the sealing plate (700) by a fastening means.

[0084] Additionally, a settling space (9222) formed at a certain depth is formed on the inside of the support housing (922). In this case, the settling space (9222) is configured to coincide with the center line of the insertion hole (730) of the sealing plate (700).

[0085] The above second adjusting bolt (924) is fastened to one end of the support housing (922) and the other end is maintained in a state of being inserted into the mounting space (9222).

[0086] The first pressure member (926) is inserted into the mounting space (9222) of the support housing (922) and moves forward or backward depending on the rotational direction of the second adjustment bolt (924).

[0087] The second pressure member (928) is inserted at one end into the mounting space (9222) of the support housing (922), and the other end presses one end of the second sealing pusher (600) through the insertion hole (730) of the sealing plate (700).

[0088] In addition, it includes a compression spring (927) configured between the first and second compression members (926)(928) to provide elasticity, thereby absorbing external forces such as vibration or impact acting internally or externally and elastically supporting the compression force of the second compression member (928) without affecting it.

[0089] In addition, it includes a sealing ring (929) that is inserted into the insertion hole (730) of the sealing plate (700) and supports the insertion of the second pressure member (928) inside, thereby maintaining the sealing of the insertion hole (730) even when the second pressure member (928) moves forward or backward.

[0090] The sealing device of the oil reduction system configured as described above is configured such that a first sealing pusher (200), a sealing packing (300), a stop ring (400), a sealing filler (500), a stop ring (400), a sealing packing (300), a second sealing pusher (600), and a sealing plate (700) are sequentially configured on one end of a fixed plate (100), and a sealing housing is configured between the fixed flange (100) so as to protect the first sealing pusher (200), the sealing packing (300), the stop ring (400), the sealing filler (500), the stop ring (400), the sealing packing (300), and the second sealing pusher (600).

[0091] In addition, the first adjusting unit (910) is configured at one end of the sealing housing so that the first sealing pusher (200) presses the sealing packing (300), thereby improving the sealing force, and the second adjusting unit (920) is configured at one end of the sealing plate so that the second sealing pusher (600) presses the sealing packing (300), thereby improving the sealing force.
