DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1

[0034] Reference Figure 1-Figure 8 , an edible vegetable oil processing and purification equipment, including a cleaning barrel 1 and a step 2, a filter barrel 3 is fixedly installed on the top of the cleaning barrel 1, a filter blockage cleaning mechanism 4 is arranged inside the cleaning barrel 1, a centrifugal filtering mechanism 5 is arranged inside the filtering barrel 3, and the centrifugal filtering mechanism 5 includes a filter screen 51.

[0035] An L-shaped connecting plate 6 is fixedly installed on one side of the top end of the step 2 , a pressing box 7 is fixedly installed on the top of one end of the L-shaped connecting plate 6 , and a transverse centrifugal pressing mechanism 8 is arranged inside the pressing box 7 .

[0036] In order to realize the centrifugal pressing of vegetable oil, a transverse centrifugal pressing mechanism 8 is set up, including a hydraulic cylinder 81, the mounting surface of the hydraulic cylinder 81 is fixedly mounted on one side surface of the pressing box 7, the telescopic end of the hydraulic cylinder 81 penetrates and extends to the interior of the pressing box 7, and the telescopic end of the hydraulic cylinder 81 is fixedly mounted with a pressure plate 82.

[0037] Specifically implemented in this way, by adjusting the hydraulic system, the pressing force can be easily changed to adapt to oils with different hardness and oil content; the telescopic end of the hydraulic cylinder 81 directly acts on the pressing plate 82, without the need for a complex transmission mechanism, and the structure is more compact.

[0038] An operating door groove 83 is opened on one side surface of the pressing box 7, and an operating sealing door 84 is hingedly and sealedly installed on one side surface of the operating door groove 83. A guide plate 85 is fixedly installed on the inner bottom wall of the pressing box 7, and a guide pipe 86 is fixedly installed on the bottom of the guide plate 85. The feed end of the guide pipe 86 is fixedly connected to the interior of the pressing box 7, and the bottom end of the guide pipe 86 is fixedly connected to the top of the filter barrel 3.

[0039] Specifically, the design of the operating door slot 83 enables the operating sealing door 84 to be hinged and sealed, which is convenient to open and close. In this way, when it is necessary to inspect or replace internal components, the inside of the pressing box 7 can be quickly and conveniently entered; the operating sealing door 84 can be sealed when closed to ensure that the oil will not leak during the pressing process and keep the production environment clean; the guide plate 85 is installed on the inner bottom wall of the pressing box 7, which helps to guide the oil residue to the guide pipe 86, and the guide pipe 86 guides the pressed mixture to the filter barrel 3; the oil is directly transported to the filter barrel 3 through the guide pipe 86, which reduces the chance of oil contacting the air.

[0040] A centrifugal rotating motor 87 is also fixedly installed on one side surface of the pressing box 7, and a rotating shaft 88 is fixedly installed on the output end of the centrifugal rotating motor 87 through a coupling, and a rotating sprocket 89 is fixedly installed on one end of the rotating shaft 88. The left end surface of the pressing box 7 is rotatably connected to a driven shaft 810 through a bearing, and a driven sprocket 811 is fixedly installed on one end of the driven shaft 810, and the groove of the driven sprocket 811 and the groove of the rotating sprocket 89 are both transmission-connected with a chain 812.

[0041] Specifically implemented in this way, the configuration of the rotating shaft 88 and the sprocket can make the material in the pressing box 7 be evenly compressed during the rotation process. During operation, the centrifugal rotating motor 87 is used to drive the rotating shaft 88 to rotate, thereby driving the rotating sprocket 89 to work, and the driven shaft 810 is rotated under the transmission of the chain 812, thereby achieving the effect of the driven sprocket 811 rotating.

[0042] The other end of the driven shaft 810 passes through and extends to the interior of the pressing box 7, and a centrifugal pressing barrel 813 is fixedly installed on one end of the driven shaft 810. The inner wall of the centrifugal pressing barrel 813 is slidably plugged into the surface of the pressure plate 82. The arc surface of the centrifugal pressing barrel 813 is also provided with oil outlet holes 814 in a circular array. A limiting slip ring 815 is also fixedly installed on the arc surface of one end of the centrifugal pressing barrel 813. A limiting slide rail 816 is fixedly installed on the inner wall of the pressing box 7. The inner wall of the limiting slide rail 816 is slidably plugged into the surface of the limiting slip ring 815.

[0043] Specifically, the centrifugal pressing barrel 813 is fixed at one end of the driven shaft 810 and rotates with the driven shaft 810 to realize the centrifugal pressing function. The inner wall of the centrifugal pressing barrel 813 is slidably connected with the surface of the pressing plate 82 to form a closed pressing space, thereby enhancing the pressing force on the oil; and the centrifugal pressing barrel 813 is horizontally arranged. When the pressing plate 82 leaves the pressing plant, it will loosen and fall and mix and stir under the centrifugal rotation, thereby improving the pressing efficiency when the pressing plate 82 moves and squeezes for the second time; the limiting slip ring 815 is fixed at one end of the centrifugal pressing barrel 813, and is slidably connected with the limiting slide rail 816 on the inner wall of the pressing box 7, thereby limiting the moving range of the centrifugal pressing barrel 813, so that it can only perform rotational movement, and controlling the centrifugal pressing barrel 813 to rotate smoothly.

[0044] The rotating motion of the centrifugal pressing barrel 813 generates centrifugal force, which helps to squeeze out the oil from the oil. Compared with static pressing, centrifugal rotary pressing can extract oil faster and improve production efficiency; the centrifugal pressing barrel 813 is placed horizontally so that the oil is evenly compressed during the pressing process. The damage to the oil caused by uneven pressing is reduced, and the oil yield and oil quality are improved. After a period of pressing, the pressing plate 82 is controlled to leave the pressing plant. The pressing plant will be broken up under the weight of the horizontal placement and the centrifugal motion. When the pressing operation is performed again, it will be squeezed by the pressing plate 82 again, which increases the chance of the oil being squeezed out. It can not only achieve efficient and high-quality oil extraction, but also improve the overall production efficiency and reduce costs through continuous pressing operations and automated processes.

[0046] Specifically, the connection blocks 51 are arranged in a ring array in groups of four and fixed to the inner wall of the filter barrel 3 through the mounting ring tube 52, forming a stable filtering structure. The overall stability of the filtering mechanism is enhanced, and the structural deformation that may occur during high-speed rotation is reduced; the connecting hole 53 and the adapter groove 54 on the mounting ring tube 52 are designed so that the filter net 51 can effectively screen and the grease can flow out smoothly.

[0048] Specifically, the bottom end of the filter screen 51 is slidably connected with the plug hole 57 through a sealing ring, thereby ensuring the sealing of the filtering process, preventing the leakage of oil and grease, and ensuring the cleanliness of the production environment; the meshing of the middle gear 512 with the surrounding gears 512, and the meshing of the gear 512 with the ring gear 510 form a precise planetary transmission system; driven by the gear 512 and the rotating shaft 511, the filter screen 51 can be centrifugally rotated, thereby improving the filtering efficiency, accelerating the speed of oil residue separation, and improving production efficiency.

[0049] A protective cover 513 and a driving motor 514 are fixedly mounted on the bottom of the annular slide rail 59 . The driving motor 514 is located inside the protective cover 513 . The output end of the driving motor 514 is fixedly mounted on the bottom of the middle rotating shaft 511 via a coupling.

[0050] Specifically implemented in this way, the protective cover 513 can protect the driving motor 514 and its connecting parts from the invasion of external impurities and grease, thereby extending the service life of the driving motor 514 and reducing the frequency of maintenance and replacement; the use of the motor allows the rotation of the filter 51 to be automatically controlled, reducing manual intervention.

[0052] Specifically implemented in this way, the telescopic end of the cylinder 41 can penetrate and extend into the interior of the cleaning barrel 1, and by controlling the telescopic movement of the cylinder 41, the automatic cleaning of the filter 51 can be achieved; the spray guns 43 distributed in a linear array along the vertical direction on the cleaning water pipe 42 can efficiently clean the filter 51, ensuring the cleanliness of the filter 51 during the cleaning process and improving the filtration efficiency; when cleaning is required, it is only necessary to control the filter to move downward for centrifugal and efficient cleaning, thereby increasing the service life of the filter 51.

[0053] By providing a filter blockage cleaning mechanism 4 inside the cleaning barrel 1, it is helpful to regularly clean the filter screen 51, prevent the filtration efficiency from decreasing due to the accumulation of impurities, and ensure the continuity and stability of the production process; by providing a centrifugal filtering mechanism 5 inside the filter barrel 3, oil and solid impurities can be effectively separated, and the purity of the oil product can be improved.
