Description

Technical Field

[0001] This utility model relates to the field of edible oil production technology, specifically to a high-efficiency refining and extraction device for edible oil. Background Technology

[0002] Edible oil, an indispensable food ingredient in people's daily lives, has its quality directly affecting people's health. Crude oil typically contains various impurities, such as phospholipids, free fatty acids, pigments, odor substances, waxes, and potentially harmful substances like pesticide residues and heavy metals. These impurities not only affect the appearance, odor, and taste of edible oil but also reduce its stability and nutritional value, and may even pose potential threats to human health. Therefore, in order to obtain high-quality edible oil, crude oil must undergo refining.

[0003] Existing technology involves adding an appropriate amount of water or an electrolyte solution to crude oil. Under certain temperature and stirring conditions, the phospholipids and other colloidal impurities in the crude oil absorb water and swell, agglomerating into larger particles. These particles are then separated from the oil by static sedimentation or centrifugation. However, some unagglomerated impurities still float in the solution. These impurities do not precipitate and are difficult to separate, affecting the refining quality. Utility Model Content

[0004] This invention addresses the technical problem of unagglomerated impurities floating in a solution, which do not settle, are difficult to separate, and affect the refining quality. It provides a highly efficient refining and extraction device for edible oils.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency refining and extraction device for edible oil, comprising: a refining box, a vertically formed chute inside the refining box, a slider slidably connected within the chute, the slider being connected to a semi-circular filter plate one and a semi-circular filter plate two, the semi-circular filter plate one and the semi-circular filter plate two being mirror images of each other, the slider being connected to a cover plate via a hydraulic cylinder, the cover plate being connected to the upper part of the refining box, a semi-circular plate being connected to the bottom of the refining box, the semi-circular plate and the semi-circular filter plate two being able to be joined together to form a complete circle, a corresponding conveying shaft being rotatably connected to the side wall of the refining box at the center of the semi-circular filter plate one and the semi-circular plate two, the conveying shaft being connected to a spiral blade, the two spiral blades respectively contacting the inner wall of the semi-circular filter plate one and the semi-circular plate two, and a debris removal mechanism being connected to the side wall of the refining box at the end of the spiral blade conveying.

[0006] Preferably, the impurity removal mechanism includes an impurity removal pipe, a spiral blade located inside the impurity removal pipe, a refining box connected to a vertical cylinder via the impurity removal pipe, a slag removal shaft rotatably connected to the bottom wall of the vertical cylinder, the slag removal shaft being connected to the slag removal spiral blade, an oil discharge pipe connected to the bottom of the vertical cylinder, and a valve installed inside the oil discharge pipe.

[0007] Preferably, the lower side wall of the refining box is connected to multiple air inlet branch pipes, each of which is connected to the main air inlet pipe. The main air inlet pipe is connected to the air outlet of the air pump. The air inlet branch pipes are inclined and are equipped with one-way air inlet valves inside.

[0008] Preferably, the first and second semicircular filter plates are composed of a semicircular support and a stainless steel filter screen. The semicircular support has holes and is connected to the slider.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The crude oil undergoes initial filtration after passing through the first semi-circular filter plate, removing large particulate impurities. The initial filtered impurities are conveyed to the impurity removal mechanism by the upper spiral blades. An electrolyte aqueous solution is added to the crude oil, causing colloidal impurities to absorb water, swell, agglomerate into larger particles, and precipitate. After precipitation, the second semi-circular filter plate is controlled to slide down and engage with the first semi-circular filter plate. During the engagement process, impurities floating in the aqueous solution are filtered out and adhere to the second semi-circular filter plate. The lower spiral blades scrape off the precipitate on the first semi-circular filter plate and the impurities on the second semi-circular filter plate, conveying them to the impurity removal mechanism to complete the impurity removal. In this way, large particulate impurities, unprecipitated impurities, and precipitated impurities are filtered out, resulting in a very good refining effect.

[0011] The air is injected into the container at the bottom of the refining box through the intake manifold, instead of traditional stirring, to avoid impurities adhering to the stirring blades and being difficult to clean. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] The following is in conjunction with the appendix Figures 1-3 This embodiment describes a high-efficiency refining and extraction device for edible oil, comprising: a refining box 1, a vertically formed chute 2 inside the refining box 1, a slider 3 slidably connected inside the chute 2, the slider 3 being connected to a semi-circular filter plate 4 and a semi-circular filter plate 5, the semi-circular filter plate 4 and the semi-circular filter plate 5 being mirror images of each other, the slider 3 being connected to a cover plate 7 via a hydraulic cylinder 6, the cover plate 7 being connected to the upper part of the refining box 1, a semi-circular plate 8 being connected to the bottom inside the refining box 1, the semi-circular plate 8 and the semi-circular filter plate 5 being able to be assembled into a complete circle, a corresponding conveying shaft 9 being rotatably connected to the side wall of the refining box 1 at the center of the semi-circular filter plate 4 and the semi-circular plate 8, the conveying shaft 9 being connected to a spiral blade 10, the two spiral blades 10 being in contact with the inner walls of the semi-circular filter plate 4 and the semi-circular plate 8 respectively, and a waste removal mechanism 11 being connected to the side wall of the refining box 1 at the end of the conveying of the spiral blade 10.

[0020] Crude oil is injected into the refining tank 1 and undergoes initial filtration through the semi-circular filter plate 4 to remove large particulate impurities. The crude oil level is located below the semi-circular filter plate 5. The power drives the conveyor shaft 9 to rotate, which in turn drives the upper spiral blade 10 to rotate. The initial filtered impurities are conveyed by the upper spiral blade 10 to the impurity removal mechanism 11. An electrolyte aqueous solution is added to the crude oil. The colloidal impurities absorb water and swell, agglomerating into larger particles and settling. The sediment falls onto the semi-circular plate 8. After sedimentation, the hydraulic cylinder 6 controls the semi-circular filter plate 5 to slide down and engage with the semi-circular plate 8. During the engagement process, impurities floating in the aqueous solution are filtered out and adhere to the semi-circular filter plate 5. The lower spiral blade 10 scrapes off the sediment on the semi-circular plate 8 and the impurities on the semi-circular filter plate 5 and conveys them to the impurity removal mechanism 11 to complete the impurity removal. In this way, large particulate impurities, unprecipitated impurities, and precipitated impurities are filtered out, resulting in a very good refining effect.

[0021] The impurity removal mechanism 11 includes an impurity removal pipe 111, a spiral blade 10 located inside the impurity removal pipe 111, a refining box 1 connected to a vertical cylinder 112 via the impurity removal pipe 111, a slag discharge shaft 113 rotatably connected to the bottom wall of the vertical cylinder 112, the slag discharge shaft 113 being connected to the slag discharge spiral blade 114, and an oil discharge pipe 12 connected to the bottom of the vertical cylinder 112, with a valve installed inside the oil discharge pipe 12.

[0022] Large particles, unprecipitated impurities, and precipitated impurities are transported into the vertical cylinder 112 by the spiral blade 10. The power drives the slag discharge shaft 113 to rotate. The slag discharge shaft 113, through the slag discharge spiral blade 114, drives all impurities to rise to the upper part of the liquid surface for discharge, thus completing the impurity discharge. When discharging oil, simply open the oil discharge pipe 12 valve.

[0023] The lower side wall of the refining box 1 is connected to multiple air inlet branch pipes 14. Each air inlet branch pipe 14 is connected to the main air inlet pipe 13. The main air inlet pipe 13 is connected to the air outlet of the air pump. The air inlet branch pipes 14 are inclined and have a one-way air inlet valve inside.

[0024] The air pump injects air through the main air intake pipe 13, and the air is injected into the refining box 1 through the branch air intake pipe 14, which drives the crude oil to flow, replacing the traditional stirring. This avoids the residue adhering to the stirring blades and being difficult to clean. The branch air intake pipe 14 is set at an angle to promote the lateral flow of crude oil and improve the stirring effect.

[0025] The semi-circular filter plate 4 and the semi-circular filter plate 5 are composed of a semi-circular support and a stainless steel filter screen 15. The semi-circular support has holes and is connected to the slider 3.

[0026] The stainless steel filter screen is wear-resistant and easy to replace.
