Description

Technical Field

[0001] The utility model relates to the field of rapeseed oil processing, in particular to filtering equipment for processing rapeseed oil by ancient method. Background Art

[0002] The ancient oil pressing technology involves more than a dozen steps, including rapeseed selection, shelling, seed frying, grinding, embryo steaming, cake making, cake stepping, pressing, impact pressing, oil collection, sedimentation, and waking up in a jar. It embodies the wisdom and culture of the Chinese working people.

[0003] The first product of rapeseed oil squeezed by the traditional method is called crude oil, and finished oil can only be obtained after filtering. The filtration equipment of rapeseed oil usually uses centrifugal filtration equipment, which uses the centrifugal principle to realize the stratification of different substances under the high-speed rotation of the motor. The gravity of essential oil is smaller than that of impurities. Therefore, when the inner barrel of the equipment rotates at high speed, impurities will stick to the wall of the inner barrel. Crude oil contains a lot of phospholipids, so 80° salt water will be added to the rapeseed oil when filtering, and the phospholipids will decompose when encountering water.

[0004] Centrifugal oil filtering equipment can filter oil once every five minutes. The amount of oil filtered each time is related to the size of the equipment, usually about 80 kilograms. The inner barrel of the oil filtering equipment, as the main working part, will rotate at high speed to centrifuge the crude oil, and then the filter residue will adhere to the wall of the inner barrel. Workers need to stop the machine for manual cleaning and use a scraper to scrape off the adhered filter residue. The oil inlet of the outer barrel is at a certain height from the bottom of the inner barrel, which makes it more troublesome for workers to clean and takes a long time. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a filtering device for processing rapeseed oil by the traditional method to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering device for processing rapeseed oil by the traditional method, comprising an outer barrel, an inner barrel being movably installed inside the outer barrel, an oil pipe being arranged at the bottom of the inner barrel, and the oil pipe being connected to a motor via a pulley assembly, a base being installed at the top of the oil pipe, and a turntable being rotatably connected to the top of the base, and a scraper being arranged on the side of the turntable, and threaded holes being provided inside the turntable and the base and threaded rods being installed.

[0007] By adopting the above technical solution, two sets of rotatable scrapers are provided to scrape the inner wall of the inner barrel, so that the filter residue attached to the side of the inner barrel wall can be effectively scraped off, and the scraper can quickly clean the filter residue on the inner wall of the inner barrel.

[0008] The utility model is further configured that the oil pipe is rotatably connected to the outer barrel, and an electromagnetically controlled liquid flow valve is arranged inside the oil pipe.

[0009] By adopting the above technical solution and arranging an electromagnetically controlled liquid flow valve inside the oil pipe, the discharge of the filtered essential oil can be controlled.

[0010] The utility model is further configured that the scrapers are provided in two groups, and the two groups of scrapers are symmetrically arranged, and the scrapers can fit the inner wall of the inner barrel.

[0011] By adopting the above technical solution and symmetrically arranging two groups of scrapers, the internal components of the inner barrel can maintain a balanced center of gravity, thereby preventing the inner barrel from vibrating violently when rotating.

[0012] The utility model is further configured that a convex block is arranged on the top of the turntable, and a matching turning handle is movably installed on the top of the turntable.

[0013] By adopting the above technical solution, a protrusion is arranged on the top of the turntable, and a matching turning handle is arranged, so that a worker can drive the turntable to rotate by the turning handle. The filtering equipment is in the studio, and the turning handle is not installed inside.

[0014] The utility model is further configured that a bracket is installed at the bottom of the outer barrel, and an oil outlet pipeline is installed at the top of the bracket below the oil pipe.

[0015] By adopting the above technical solution, the outer barrel can be supported by arranging a bracket, and an oil outlet pipe is arranged, so that the essential oil discharged through the oil pipe can enter the oil outlet pipe and then enter the filter box.

[0016] The utility model is further configured that a filter box is provided on one side of the bracket, and a filter screen is movably installed on the bottom of the filter box.

[0017] By adopting the above technical solution and setting a filter screen, the foam of the essential oil can be filtered. In the case where foam is generated when the amount of salt water added by the staff and the temperature are inaccurate, the foam can be directly filtered.

[0018] The utility model is further configured that the outer barrel is movably mounted with a cover plate by arranging a buckle, and a funnel is arranged on the top of the cover plate.

[0019] By adopting the above technical solution, by arranging a movable cover on the top of the outer barrel, compared with the existing centrifugal filtering equipment, the cover of the outer barrel can be opened, which can increase the operating space for workers to clean, making the cleaning work convenient and efficient.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model can effectively scrape off the filter residue attached to the side of the inner barrel wall by arranging two groups of rotatable scrapers to rotate and scrape the inner wall of the inner barrel. When the inner barrel is rotating, tightening the threaded rod can lock the base and the turntable to ensure that the scraper rotates synchronously when the inner barrel rotates. When the inner barrel needs to be cleaned, the threaded rod is rotated to release the restriction between the base and the turntable by the threaded rod, so that the turntable can rotate on the base, and the turntable is driven to rotate by the turn handle matching the protrusion, so that the scraper rotates in contact with the inner wall of the inner barrel, so that the scraper can quickly clean the filter residue on the inner wall of the inner barrel.

[0022] 2. The utility model can perform secondary filtration on the filtered essential oil by setting a filter box and a filter screen. When filtering the crude oil, the amount of salt water and the temperature are not accurately controlled, which will cause the produced essential oil to carry a large amount of foam. Therefore, the produced essential oil enters the filter box and is filtered through the screen to effectively remove the foam, and the screen can be removed for easy cleaning.

[0023] 3. The utility model provides a movable cover plate on the top of the outer barrel, so that the cover plate and the funnel can be removed. When the inner barrel is cleaned of filter residue, the inner barrel can be included outside by removing the cover plate, thereby increasing the operating space for workers during cleaning and making the cleaning work more convenient and efficient.

When the inner barrel 2 is rotating, tightening the threaded rod 8 can lock the base 5 and the turntable 6, ensuring that the scraper 7 rotates synchronously when the inner barrel 2 rotates. When the inner barrel 2 needs to be cleaned, the threaded rod 8 is rotated to release the restriction of the threaded rod 8 on the base 5 and the turntable 6, so that the turntable 6 can rotate on the base 5, and the turntable 6 is driven to rotate by the turning handle matching the protrusion 9, so that the scraper 7 rotates in contact with the inner wall of the inner barrel 2, so that the scraper 7 can quickly clean the filter residue on the inner wall of the inner barrel 2.

[0036] See also Figure 4 The oil pipe 3 and the outer barrel 1 are rotatably connected, and an electromagnetically controlled liquid flow valve is arranged inside the oil pipe 3. By arranging the electromagnetically controlled liquid flow valve inside the oil pipe 3, the discharge of the filtered essential oil can be controlled.
