Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing, specifically to a sedimentation device for rapeseed oil processing. Background Technology

[0002] Rapeseed oil is a vegetable oil extracted from rapeseed seeds. Due to its mild taste and high heat resistance, it is widely used in cooking. Rich in unsaturated fatty acids and vitamin E, rapeseed oil is suitable not only for high-temperature stir-frying and deep-frying but also for cold dishes, making it a healthy choice for daily diets. During the refining process of rapeseed oil, solid impurities in the oil naturally settle through a sedimentation process. The sediment includes tiny solid particles, fine impurities, and incompletely decomposed substances. Sedimentation effectively improves the purity of the oil.

[0003] In the traditional rapeseed oil processing, sedimentation equipment is often used alone for sedimentation. This equipment relies on natural settling or gravity to settle solid particles, which is a slow process with low sedimentation efficiency. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] First embodiment:

[0028] See Figures 1-3 As shown, this utility model provides a sedimentation device for rapeseed oil processing, including a secondary sedimentation chamber 1. The top and bottom of the secondary sedimentation chamber 1 are respectively provided with an oil inlet pipe 103 and an outlet pipe 101. An electric control valve is provided on the outlet pipe 101. An oil outlet pipe 102 is provided on the outer wall of the secondary sedimentation chamber 1. The oil outlet pipe 102 is used to assist in the discharge of the upper layer of rapeseed oil.

[0029] The top surface of the secondary sedimentation tank 1 is connected to a motor 4 via a telescopic hydraulic cylinder 5. When the telescopic hydraulic cylinder 5 extends or retracts, it can drive the motor 4 to move up and down. The output end of the motor 4 extends into the interior of the secondary sedimentation tank 1 and is connected to a cylinder frame 3 via a rotating rod. The bottom of the cylinder frame 3 is provided with a mesh-like filter cover 301. The bottom end of the oil inlet pipe 103 is correspondingly set with the opening of the cylinder frame 3. The inner cylinder 2 is located between the secondary sedimentation tank 1 and the cylinder frame 3. The side wall of the inner cylinder 2 has an oil guide hole 202. The bottom of the inner cylinder 2 is connected to an inner discharge pipe 201 corresponding to the outer discharge pipe 101.

[0030] The bottom of the filter cover 301 has a discharge hole 302, and the inner cylinder 2 is provided with a sealing plug 6 that seals the discharge hole 302.

[0031] When the device is in use, the oil requiring sedimentation is guided into the cylinder 3 through the oil inlet pipe 103. As the oil passes through the cylinder 3 and reaches the filter cover 301, the motor 4 drives the rotating rod to rotate, thus rotating the cylinder 3 and the filter cover 301. The rotating filter cover 301 utilizes centrifugal force to initially separate the oil, leaving larger impurities inside. The oil accumulates in the inner cylinder 2 and undergoes initial sedimentation until it aligns with the oil guide hole 202. Then, it is guided through the oil guide hole 202 to the secondary sedimentation chamber 1 for secondary sedimentation. The oil undergoes a second sedimentation process in the secondary sedimentation chamber 1 until the oil... When the material corresponds to the oil outlet pipe 102, the upper layer of oil is discharged through the oil outlet pipe 102. In the device structure, oil impurities generated inside the secondary sedimentation tank 1 can be discharged through the outer discharge pipe 101, and oil impurities generated inside the bottom surface of the inner cylinder 2 can be discharged through the inner discharge pipe 201. When processing oil impurities generated inside the filter cover 301, the telescopic hydraulic cylinder 5 is extended, and the motor 4 drives the rotating rod and the cylinder frame 3 to move upward until the discharge hole 302 is separated from the sealing plug 6, thus opening the discharge hole 302. The oil impurities inside the filter cover 301 are then guided into the inner cylinder 2 and discharged through the inner discharge pipe 201.

[0032] In the device, the inner cylinder 2 is provided with a sealing plug 6 that rotates and seals with the discharge hole 302. The sealing plug 6, which is in cooperation with the rotating seal, seals the discharge hole 302 and at the same time assists the discharge hole 302 to rotate outside the sealing plug 6.

[0033] In another embodiment, a sealing plug 6 is rotatably connected inside the inner cylinder 2. The sealing plug 6 is sealed to the discharge hole 302. In this way, when the filter cover 301 rotates, the sealing plug 6 can be rotated synchronously, and the discharge hole 302 can be sealed at the same time as the filter cover 301 rotates.

[0034] The second embodiment differs from the first embodiment in that:

[0035] The outgoing feed pipe 101 is zigzag-shaped, and the bottom end of the inner feed pipe 201 passes through the outgoing feed pipe 101. The inner feed pipe 201, the outgoing feed pipe 101, the oil outlet pipe 102, and the oil inlet pipe 103 are all equipped with electrically controlled valves. In the structure of the device, the inner feed pipe 201 and the outgoing feed pipe 101 are welded together to support the inner cylinder 2. The inner feed pipe 201 and the outgoing feed pipe 101 can respectively guide two kinds of precipitated impurities. Since the impurity densities of the two kinds of precipitated impurities are different, this is beneficial to treat the two kinds of impurities separately.

[0036] The third embodiment differs from the first embodiment in that:

[0037] The cylinder frame 3 has a cone-shaped structure, with its large end corresponding to the oil inlet pipe 103. The cone-shaped cylinder frame 3 is used to receive the oil discharged from the oil inlet pipe 103 until the oil reaches the filter cover 301. Then, the motor 4 drives the cylinder frame 3 to rotate, and the rotating filter cover 301 filters the oil.

[0038] Furthermore, the rotating rod is rotaryly sealed with the top plate of the secondary sedimentation tank 1, and the rotating rod is connected to the cylinder frame 3 through connecting arms. There are two or three connecting arms, which are welded between the cylinder frame 3 and the rotating rod.

[0039] Preferably, the sealing plug 6 is provided with an impurity outlet hole 601. The impurity outlet hole 601 is "T" shaped, and its bottom end is corresponding to the inner discharge pipe 201. The telescopic hydraulic cylinder 5 can drive the motor 4 to move up and down, thereby driving the rotating rod and the cylinder frame 3 to move up and down, realizing the adjustment of the position of the discharge hole 302 and the sealing plug 6. When the impurity outlet hole 601 corresponds to the inner wall of the filter cover 301, the impurities inside the filter cover 301 can be guided out through the impurity outlet hole 601. When the impurity outlet hole 601 is located outside the filter cover 301, that is, when the impurity outlet hole 601 is located below the filter cover 301, the impurity outlet hole 601 is blocked, so that the oil inside the filter cover 301 can be filtered by rotating the cylinder frame 3 through the motor 4. After the impurity outlet hole 601 is provided on the sealing plug 6, it is ensured that the filter cover 301 and the sealing plug 6 are always in contact, avoiding the slippage between the discharge hole 302 and the sealing plug 6.

[0040] The fourth embodiment differs from the first embodiment in that:

[0041] The oil guide hole 202 is located above the filter cover 301, away from the oil outlet pipe 102 and above it. At the position of the oil guide hole 202, during the rotation of the cylinder frame 3, the material inside the cylinder frame 3 can be screened through the mesh on the surface of the filter cover 301, leaving larger solid impurities inside the filter cover 301. Because the oil guide hole 202 is located above the filter cover 301, the oil entering the inner cylinder 2 can undergo primary sedimentation treatment until the oil level reaches a certain point. The oil is guided from the oil guide hole 202 to the interior of the secondary sedimentation tank 1 for secondary sedimentation treatment. Impurities in the oil are concentrated on the bottom surface of the inner cylinder 2 and discharged through the inner discharge pipe 201. Since the oil guide hole 202 is located far from the oil outlet pipe 102, the oil discharged from the inner cylinder 2 undergoes secondary sedimentation treatment inside the secondary sedimentation tank 1 until the oil exceeds the oil outlet pipe 102, so that the upper layer of oil can be discharged through the oil outlet pipe 102. The impurities are left at the bottom of the secondary sedimentation tank 1 and can be discharged through the outer discharge pipe 101.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
