Hereinafter, an embodiment of an oil treatment device according to the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or sizes of components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

1 is a diagram schematically showing an oil processing device according to an embodiment of the present invention. Referring to Figure 1, the oil processing device 1 according to an embodiment of the present invention includes a frame part 10, a support part 20, an elevating part 30, a filter part 40, and a storage unit. It may include part 50.

The frame portion 10 forms the framework of the oil processing device 1, and a support portion 20, an elevating portion 30, a filter portion 40, and a storage portion 50 can be mounted thereon. The frame unit 10 may be changed into various shapes depending on the working environment or design. The frame portion 10 may be made of metal material. The frame portion 10 can be moved as needed.

The support portion 20 is mounted on the frame portion 10 to allow oil to pass therethrough. For example, the support portion 20 is disposed in the center of the frame portion 10 and may be made of a metal material. The support portion 20 may have a gap formed to allow oil to pass through while filtering out foreign substances.

The lifting unit 30 is mounted on the frame unit 10, is disposed above the support unit 20, and can be moved up and down. For example, the lifting unit 30 may be mounted on the frame unit 10 and disposed above the support unit 20. When the lifting part 30 descends and comes into close contact with the support part 20, a space in which oil can be temporarily stored may be formed inside the lifting part 30. Also, when contaminated oil is supplied to the internal space of the lifting unit 30, foreign substances can be filtered out by the filter unit 40 and the support unit 20.

The filter unit 40 is seated on the support unit 20 and can filter oil. For example, the filter unit 40 may be unwound while wound on one side of the frame unit 10 and recovered while wound on the other side of the frame unit 10. The filter unit 40 may pass between the support unit 20 and the lifting unit 30. With the filter unit 40 seated on the support unit 20, the lifting unit 30 may be lowered to form an oil storage space.

The storage unit 50 is mounted on the frame unit 10 and can store oil that has passed through the receiving unit 20 after being filtered by the filter unit 40. For example, the storage unit 50 is disposed below the support unit 20 and can store oil that has passed through the support unit 20 so that it reaches a set water level.

Meanwhile, the cooking unit (not shown) may heat stored oil to cook food. This cooking unit is connected to the lifting unit 30 to supply contaminated oil to the lifting unit 30, and is connected to the storage unit 50 to reuse the purified oil.

Figure 2 is a diagram schematically showing a support portion according to an embodiment of the present invention, and Figure 3 is a cross-sectional view schematically showing a support slit portion according to an embodiment of the present invention. Referring to Figures 2 and 3, the support portion 20 according to an embodiment of the present invention may include a support frame portion 21 and a support slit portion 22.

The support frame unit 21 may be mounted on the frame unit 10. For example, the support frame part 21 may be coupled to the central part of the frame part 10 and become an edge of the support part 20. The support frame portion 21 may have a rectangular shape.

A plurality of support slit parts 22 are arranged in a row inside the support frame part 21 to support the filter part 40 and allow oil to pass therethrough. For example, the support slit portion 22 may have a length in the moving direction of the filter portion 40, and a plurality of support slit portions 22 may be arranged in parallel to support the filter portion 40. In addition, the support slit portion 22 has a length in a direction perpendicular to the moving direction of the filter portion 40, and a plurality of support slit portions 22 may be arranged in parallel to support the filter portion 40.

The support slit portion 22 may have an inverted triangle shape in cross section. For example, the support slit portion 22 may have the shape of an inverted triangle where the upper end is wider than the lower end, and may be arranged to be spaced closely apart from the adjacent supporting slit portion 22. As a result, the supporting slit portion 22 stably supports the filter portion 40, and some of the foreign matter that has passed through the filter portion 40 may be caught in the supporting slit portion 22, thereby restricting passage. In addition, the oil that has passed through the upper part of the receiving slit portion 22 can quickly descend as the gap between the receiving slit portions 22 increases.

Figure 4 is a plan perspective view schematically showing a lifting unit according to an embodiment of the present invention, and Figure 5 is a bottom perspective view schematically showing a lifting unit according to an embodiment of the present invention. Referring to Figures 4 and 5, the lifting part 30 according to an embodiment of the present invention may include a lifting support part 31, a lifting variable part 32, and a lifting cover part 33.

The lifting support unit 31 may be mounted on the frame unit 10. As an example, the lower end of the plurality of lifting supports 31 is fixed to the frame 10 and is coupled to the upwardly extending support bar 311 and the upper end of the support bar 311 to form a support 20. ) may include a support upper plate portion 312 fixed to the upper part. The support bar portion 311 may be disposed outside the support frame portion 21.

The lifting variable part 32 is mounted on the lifting support part 31 and can have a variable length. For example, the lifting variable part 32 is mounted on the support top plate part 312, and the length is variable up and down, so that the height of the lifting cover part 33 can be adjusted.

The lifting cover part 33 is connected to the lifting variable part 32, moves up and down according to the length of the lifting variable part 32, is spaced apart from the supporting part 20, or is seated on the supporting part 20, and the lower side is open. Thus, a space can be formed inside. For example, the lifting cover part 33 is coupled to the lifting variable part 32 and extends downward from the edge of the cover top part 331 whose height is adjusted, and when the cover top part 331 is lowered. It may include a cover side plate portion 332 mounted on the support portion 20. A cover sealing portion 333 is formed on the bottom of the cover side plate portion 332 to maintain airtightness, and rigidity can be maintained by the cover reinforcement portion 334 connecting the opposing cover side plate portions 333.

A hydraulic cylinder may be used as the elevation variable part 32. These hydraulic cylinders have advantages over pneumatic cylinders when working with high temperature oil.

In other words, it is difficult for the pneumatic cylinder to respond to fluctuating pressure or an instantaneous increase in pressure in the internal space of the lifting cover 33, and when the oil over 180 degrees is heterogeneously overpressured, gap leakage may occur due to pressure changes depending on temperature. , Hydraulic cylinders can prevent this and maintain a sealed state by precisely controlling the pressure.

Additionally, the exterior of the pneumatic cylinder is made of rubber, so its performance and lifespan are shortened if deformation increases due to the heat from high-temperature oil. However, the hydraulic cylinder has a strong exterior and safe structure, making it suitable for application to the system.

In addition, since most pneumatic cylinders use the pressure within the entire piping of the factory where the equipment is installed, it poses a risk to the operation of the equipment when pressure changes or power is lost, and the smoke point leaked within the internal space of the lifting cover (33) Oil exceeding the temperature may cause a large-scale fire, but since the hydraulic cylinder operates independently, the internal space of the lifting cover (33) along with the safety check valve is maintained sealed even when power is lost, thereby maintaining high temperature. Oil can be safely processed.

In addition, pneumatic cylinders are difficult to use at high pressure because there is a risk of explosion of parts such as air tanks, but hydraulic cylinders can produce strong force by using high pressure compared to pneumatic cylinders.

In addition, when the left and right pairs of hydraulic cylinders are arranged spaced apart, a uniform pressing force is provided to the lifting cover 33, thereby preventing oil leakage from corners or edges due to internal overpressure or abnormal pressure waves of the lifting cover 33. can be prevented.

The lifting unit according to an embodiment of the present invention may further include a lifting oil part 34 and a lifting pressure part 35.

The lifting oil part 34 is connected to the lifting cover part 33 and can supply oil to the inside of the lifting cover part 33. For example, an oil hole part 391 is formed in the cover top part 331, and after cooking, contaminated oil is contaminated into the inside of the lifting cover part 33 through the lifting oil part 34 that guides it to the oil hole part 391. Oil can be supplied.

The lifting pressure unit 35 is mounted on the lifting cover 33 and can adjust the internal pressure of the lifting cover 33. For example, the lifting pressure unit 35 may include a first pressure unit 351 and a second pressure unit 352. A first hole portion 381 is formed in the cover top plate portion 331, and the first pressure portion 351 can open and close the first hole portion 381. A second hole portion 382 is formed in the cover upper plate portion 331, and the second pressure portion 352 supplies fluid through the second hole portion 382 to increase the internal pressure of the lifting cover portion 33. . The fluid supplied through the second hole portion 382 is dispersed by the cover distribution portion 335 disposed below the second hole portion 382, so that the oil can be uniformly pressed.

That is, when the cover top plate portion 331 is lowered and the cover side plate portion 332 comes into close contact with the support portion 20, contaminated oil is supplied through the oil hole portion 391. And, when the first hole part 381 is closed and the internal space is sealed by the lifting cover part 33 and the support part 20, the lifting cover part 33 is caused by the fluid flowing in through the second hole part 382. The internal pressure rises. As a result, the oil sequentially passes through the filter unit 40 and the support part 20 and is stored in the storage part 50, and foreign substances are filtered out from the filter part 40 and the support part 20. At this time, the fluid flowing in through the second hole portion 382 can quickly dry the foreign substances filtered in the filter portion 40. When the drying of foreign substances is completed, the first hole 381 is opened to lower the internal pressure of the lifting cover 33, and the cover top plate 331 rises to separate the cover side plate 332 from the support portion 20.

It may include two connection parts 522. The second connection portion 522 may be designed to have a height corresponding to the high point of the tank storage portion 512.

The storage floating portion 53 is inserted into the storage connection portion 52 and can float in the oil. For example, the storage floating part 53 is inserted into the second connection part 522, which has a tubular shape with an open upper side, and its height may vary depending on the level of oil stored in the second connection part 522. Since the storage floating portion 53 is floating in oil, stable vertical movement may be possible without being stuck to the inner wall of the storage connection portion 52.

The storage detection unit 54 is mounted on the storage connection unit 52 and can detect the position of the storage floating unit 53. As an example, the storage detection unit 54 is mounted on the outer wall of the second connection part 522 and has a length up and down, and is mounted on the detection plate unit 541 and detects the floating storage unit 53. It may include a detection sensor unit 542. The detection sensor unit 542 is arranged in a pair spaced apart from each other up and down, and can determine the oil level by detecting the high or low point of the floating storage unit 53. When the oil level reaches the set highest point, the operator can be notified through a separate notification means, or the oil stored in the storage tank 51 can be discharged to cook food.
