[0002] Sesame oil is a traditional Chinese condiment with a rich sesame flavor, and it is an indispensable condiment in people's daily lives. The production process of sesame oil generally includes raw material selection, roasting, crushing, low-temperature pressing, sedimentation, and filtration. After the sesame seeds are pressed to extract oil, the pressed oil usually still contains a lot of impurities, so it needs to be sedimented. The traditional method is to pour the pressed sesame oil into a sedimentation tank for settling. The sedimentation tank is equipped with an oil inlet pipe at the top and a slag outlet pipe at the bottom, and an oil outlet pipe on the outer wall of the sedimentation tank. After the impurities in the sesame oil in the sedimentation tank settle to the top of the tank, the oil outlet pipe is opened to allow the settled sesame oil in the upper part of the tank to flow out. After the sesame oil is removed, the slag outlet pipe is opened to discharge the impurities from the sedimentation tank. After the sedimentation tank is used, it usually needs to be cleaned and disinfected to reduce the possibility of residue affecting the next sedimentation. Therefore, an easy-to-clean sesame oil sedimentation device is needed.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 As shown, a sesame oil sedimentation device that is easy to clean includes a sedimentation tank 1. A sealing cover 2 is snapped onto the upper surface of the sedimentation tank 1. Two symmetrical fixing components 3 are fixedly connected to the left and right sides of the outer wall of the sealing cover 2. The outer walls of the opposite parts of the two fixing components 3 are snapped onto the left and right sides of the sedimentation tank 1, respectively. A feeding component 4 is fixedly connected to the left part of the upper surface of the sealing cover 2. A driving component 5 is fixedly connected to the inner cavity of the upper part of the sedimentation tank 1. A cleaning component 6 is fixedly installed on the inner wall of the driving component 5. The outer wall of the cleaning component 6 is movably sleeved with the inner wall of the sedimentation tank 1. A slag discharge pipe 8 is fixedly connected to the lower surface of the sedimentation tank 1. An oil discharge pipe 7 is fixedly connected to the right side of the sedimentation tank 1 and is located below the driving component 5.

[0029] First, the cleaning component 6 is installed on the inner wall of the drive component 5, so that the cleaning component 6 can be movably connected with the inner wall of the sedimentation tank 1. Then, the sealing cover 2 is snapped onto the upper surface of the sedimentation tank 1. Then, under the action of the two fixing components 3, the sealing cover 2 is fixed. Then, the feeding component 4 is opened, and sesame oil is injected into the inner cavity of the sedimentation tank 1 through the feeding component 4. Then, the feeding component 4 is closed. After sedimentation is completed, the sesame oil can be discharged through the oil drain pipe 7, and the residue at the bottom of the sedimentation is discharged through the slag outlet pipe 8. Then, under the action of the drive component 5, the cleaning component 6 can rotate and move in the inner wall of the sedimentation tank 1, thereby cleaning the inner wall of the sedimentation tank 1.

[0030] like Figure 3As shown, the two fixing components 3 include two fixing blocks 31. The upper opposing surfaces of the two fixing blocks 31 are fixedly connected to the left and right sides of the outer wall of the sealing cover 2, respectively. The inner cavities of the lower parts of the two fixing blocks 31 are threadedly connected to threaded rods 32. The outer walls of the opposing parts of the two threaded rods 32 are respectively engaged with the left and right sides of the outer wall of the sedimentation tank 1. The opposite surfaces of the two threaded rods 32 are fixedly connected to rotating wheels 33, and the two rotating wheels 33 are respectively located on the side of the two fixing blocks 31 away from the sealing cover 2.

[0031] By rotating the rotating wheel 33, the threaded rod 32 can rotate and move under the action of the fixed block 31, thereby restricting and fixing the sealing cover 2, which facilitates fixing and disassembling during use.

[0032] The feeding assembly 4 includes a feeding pipe 41, the outer wall of the feeding pipe 41 is fixedly connected to the inner cavity of the sealing cover 2, the upper part of the outer wall of the feeding pipe 41 is threadedly connected to a sealing plug 42 and the sealing plug 42 is located on the upper surface of the sealing cover 2, and the lower surface of the feeding pipe 41 is fixedly connected to a conduit 43 and the conduit 43 is located on the lower surface of the sealing cover 2.

[0033] By rotating the sealing plug 42, the sealing plug 42 can be removed from the outer wall of the feed pipe 41. At this time, sesame oil can be injected into the inner cavity of the sedimentation tank 1 through the feed pipe 41. Then, under the action of the support block 62, the sesame oil can be guided to the middle of the support frame 61, thereby ensuring that the sesame oil will not come into contact with the upper part of the inner wall of the drive assembly 5.

[0034] like Figure 4 As shown, the cleaning component 6 includes a support frame 61. The outer wall of the fixed shaft in the center of the support frame 61 is movably connected to the inner wall of the lower part of the sealing cover 2. The front, back, left and right parts of the outer wall of the support frame 61 are all fixedly connected to support blocks 62. The outer walls of the four support blocks 62 are movably connected to the annular plate 51 and the inner wall of the sedimentation tank 1, respectively.

[0035] The support frame 61 and support block 62 enhance the strength of the arc-shaped plate 66 and the arc-shaped cleaning brush 67, thereby improving cleaning efficiency.

[0036] like Figure 5 As shown, each of the four support blocks 62 has a slidingly connected locking block 63 on its inner wall. The outer wall of each of the four locking blocks 63, which is away from the support frame 61, is respectively engaged with the inner wall of the annular plate 51. The inner cavity of each of the four locking blocks 63, which is close to the support frame 61, is rotatably connected with a threaded rod 64. The outer wall of each of the four threaded rods 64, which is away from the four locking blocks 63, is respectively threadedly connected to the inner cavity of the four support blocks 62. The side of each of the four threaded rods 64, which is away from the four locking blocks 63, is fixedly connected with a rotating wheel 65, and the four rotating wheels 65 are respectively located on the side of each of the four support blocks 62 away from the annular plate 51.

[0037] By rotating the sealing plug 42, the sealing plug 42 can be removed from the outer wall of the feed pipe 41. At this time, sesame oil can be injected into the inner cavity of the sedimentation tank 1 through the feed pipe 41. Then, under the action of the support block 62, the sesame oil can be guided to the middle of the support frame 61, thereby ensuring that the sesame oil will not come into contact with the upper part of the inner wall of the drive assembly 5.

[0038] An annular guide rail 52 is fixedly connected to the upper surface of the annular plate 51, and the outer wall of the annular guide rail 52 is slidably connected to the inner cavity of the sedimentation tank 1.

[0039] The ring guide rail 52 makes the rotation of the ring plate 51 more stable and smooth, thus facilitating the rotation and movement of the support frame 61.

[0040] like Figure 6 As shown, the drive assembly 5 includes an annular plate 51, the outer wall of the annular plate 51 is rotatably connected to the inner cavity of the sedimentation tank 1, an annular bevel gear 53 is fixedly connected to the lower surface of the annular plate 51, a bevel gear 54 is meshed with the front part of the lower surface of the annular bevel gear 53, the outer wall of the bevel gear 54 is rotatably connected to the inner cavity of the sedimentation tank 1, and a rotating rod 55 is fixedly connected to the front of the bevel gear 54 and the rotating rod 55 is located in front of the sedimentation tank 1.

[0041] By rotating the rotating rod 55, the bevel gear 54 is rotated, which in turn drives the annular bevel gear 53 and the annular plate 51 to rotate and move. Under the action of the annular plate 51, the four support blocks 62 can drive the support frame 61 to rotate on the inner wall of the sedimentation tank 1, so that the arc plate 66 and the arc cleaning brush 67 can rotate and clean the inner wall of the sedimentation tank 1.

[0042] like Figure 7 As shown, the lower part of the outer wall of the support frame 61 is fixedly connected to four parts: front, back, left, and right. The upper surfaces of the four arc plates 66 are fixedly connected to the lower surfaces of the four support blocks 62 respectively. The outer walls of the four arc plates 66 are fixedly connected to arc cleaning brushes 67 respectively. The outer walls of the four arc cleaning brushes 67 overlap with the inner wall of the sedimentation tank 1 respectively.

[0043] The inner wall of the sedimentation tank 1 can be cleaned by the action of the arc plate 66 and the arc cleaning brush 67. At the same time, since the inner wall of the lower part of the sedimentation tank 1 is arc-shaped, it can be cleaned more thoroughly by the action of the arc cleaning brush 67.

[0044] The working principle of this utility model is as follows: First, the support frame 61 is placed inside the sedimentation tank 1. After adjusting its position, the threaded rod 64 is rotated by rotating the second rotating wheel 65, thereby allowing the locking block 63 to move into the inner cavity of the annular plate 51 under the restriction of the support block 62. Through the action of the four locking blocks 63, the support block 62 and the support frame 61 can be fixedly installed with the inner wall of the annular plate 51. Next, the sealing cover 2 is snapped onto the upper surface of the sedimentation tank 1. At this time, the inner wall of the lower part of the sealing cover 2 can be movably sleeved with the outer wall of the fixed shaft of the center part of the support frame 61. Then, by rotating the first rotating wheel 33, the threaded rod 32 can rotate and move under the action of the fixed block 31, thereby restricting and fixing the sealing cover 2. After installation and fixation, rotate and open the sealing plug 42 to allow sesame oil to be injected into the inner cavity of the sedimentation tank 1 through the feed pipe 41. The sesame oil is guided by the conduit 43. Then close the sealing plug 42. After sedimentation, the sesame oil can be discharged through the oil drain pipe 7, while the residue at the bottom of the sedimentation is discharged through the slag outlet pipe 8. Then, by rotating the rotating rod 55, the bevel gear 54 can be rotated, which can drive the annular bevel gear 53 and the annular plate 51 to rotate and move. Under the action of the annular plate 51, the four support blocks 62 can drive the support frame 61 to rotate in the inner wall of the sedimentation tank 1, so that the arc plate 66 and the arc cleaning brush 67 can rotate and clean the inner wall of the sedimentation tank 1.
