[0002] In the production process of grain and oil, the just-extruded crude oil needs to be filtered to filter out the debris in the crude oil and obtain relatively pure liquid oil. Commonly used filtering equipment usually makes edible oil pass through a filter screen for filtering under the action of pressure or gravity.

[0031] like Figure 1 As shown, a filtration device for processing grain and oil raw materials includes an oil inlet pipe 13, which is usually made of 304 food-grade stainless steel that is resistant to high temperature and corrosion. It is used to transport edible oil to the filtration structure for continuous filtration. This is existing technology and will not be described in detail here.

[0032] The difference is, such as Figures 1 to 3 As shown, it also includes a turntable 1 with an extended flange. Three sets of filter screens 2 are embedded in the bottom of the turntable 1. The three sets of filter screens 2 are arranged in a ring. There is a distance between the filter screens 2 and the bottom surface of the turntable 1. A guide groove 3 is provided between each pair of adjacent filter screens 2. Each pair of filter screens 2 is connected through the guide groove 3. The depth of one end of each guide groove 3 is less than that of the other end. An oil receiving tray 4 is coaxially provided at the bottom of the turntable 1. The oil receiving tray 4 is fixed to the base and is used to collect the initially filtered cooking oil. The cross-section of the oil receiving tray 4 is fan-shaped, and the axis of the oil receiving tray 4 is fully open. It also includes a motor 5. The output end of the motor 5 is fixedly connected to an output shaft 501. The output shaft 501 passes through the axis of the oil receiving tray 4 and is fixedly connected to the bottom of the turntable 1.

[0033] In this embodiment, edible oil is continuously transported to the filter screen 2 through the oil inlet pipe 13 for filtration. The edible oil after preliminary filtration falls into the oil receiving tray 4 at the bottom of the turntable 1. The bottom of the oil receiving tray 4 is connected to a conveying pipe, which can be transported to the next step for further processing. The conveying pipe here is still made of 304 food-grade stainless steel.

[0034] Meanwhile, the oil outlet end of the oil inlet pipe 13 is opposite the axial position of the filter screen 2, and the distance between the filter screen 2 and the inner bottom surface of the rotating disc 1 is not less than 6 cm, thereby preventing the edible oil from splashing everywhere and preventing impurities on the surface of the filter screen 2 from accumulating and causing the edible oil to overflow onto the flow guide groove 3.

[0035] In use, after the quantitative filtration of each group of filter screens 2, the motor 5 is started to drive the rotating disc 1 to rotate counterclockwise, and the angle of each single rotation is 120 degrees, thereby alternately replacing the filter screens 2. During the process of alternately replacing the filter screens 2, the continuously discharged edible oil can flow along the high end of the flow guide groove 3 to the low end, and finally flow into the adjacent filter screen 2 for continuous filtration. It is particularly worth mentioning that a simple buckle structure (not shown in the figure) is adopted between the filter screen 2 and the rotating disc 1, the filter screen 2 filled with impurities is rotated counterclockwise by 120 degrees and moved to the position of the sector-shaped gap of the oil receiving disc 4, and then it is removed. After cleaning the impurities, it is installed again, thereby ensuring the continuous filtration of the edible oil, and at the same time, the impurities can be cleaned in time, thereby improving the filtration effect of the edible oil.

[0036] As shown in Figure 3 As a further scheme of the present application, a partition is installed in the oil receiving disc 4, and the oil receiving disc 4 is divided into a first receiving disc 401 and a second receiving disc 402 by the partition.

[0037] In use, the oil receiving disc 4 is divided into two parts, and the edible oil continuously discharged from the oil inlet pipe 13 flows into the first receiving disc 401 after being filtered by the filter screen 2, and the first receiving disc 401 is used for receiving the edible oil filtered initially. The filter screen 2 filled with impurities to be cleaned is rotated to be directly above the second receiving disc 402 for removal, and the impurities and part of the edible oil mixed therein can be poured into the second receiving disc 402. After the edible oil in this part is deposited, it can be treated separately, thereby avoiding the waste of edible oil.

[0038] As shown in Figures 4 to 8 As shown in

[0039] The buckle assembly includes a limiting block 703 fixedly connected to one end of the rotating shaft 701 away from the filter screen 2, a clamping groove 708 is formed in the inside of the limiting block 703, a clamping block 704 is clamped and connected in the inside of the clamping groove 708, a telescopic rod 705 and a spring 706 are fixedly connected to one side of the clamping block 704 away from the limiting block 703, the spring 706 is sleeved outside the telescopic rod 705, and the telescopic rod 705 and the spring 706 are fixedly connected to the inner wall of the rotating disc 1; a second protruding block 707 is fixedly connected to one side of the clamping block 704 away from the limiting block 703, one side of the second protruding block 707 is provided as an arc surface; and the cross-sectional shapes of the limiting block 703, the clamping block 704 and the clamping groove 708 are all hexagonal.

[0040] The second receiving tray 402 is internally provided with a driving mechanism 6, and the driving mechanism 6 comprises a releasing assembly, and the releasing assembly comprises a first protrusion 602, one end of the first protrusion 602 is provided as an arc surface.

[0041] The engaging assembly is coupled with the releasing assembly.

[0042] In use, the motor 5 drives the rotating disc 1 to rotate counterclockwise, and the filter screen 2 rotates synchronously with the rotating disc 1, at the same time, the engaging assembly rotates synchronously with the filter screen 2, until the engaging assembly moves to the releasing assembly, at this time, the second protrusion 707 is pressed by the arc surface of one end of the first protrusion 602, so that the second protrusion 707 drives the clamping block 704 to move away from the limiting block 703 against the force of the spring 706, until the clamping block 704 is completely separated from the clamping groove 708, so that the limiting block 703 loses the limiting, and then the rotating shaft 701 can rotate alone.

[0043] Further, the driving mechanism 6 further comprises a driving assembly, and the driving assembly is fixedly connected to one side of the releasing assembly; the driving assembly comprises an arc-shaped rack 601, the arc-shaped rack 601 is fixedly connected to the inner bottom surface of the second receiving tray 402, and the first protrusion 602 is fixedly connected to one side of the arc-shaped rack 601.

[0044] The transmission assembly comprises a rotating shaft 701, the rotating shaft 701 is fixedly connected to the outer wall of the filter screen 2, and the umbrella gear 702 is fixedly connected to the outer side of the rotating shaft 701.

[0045] The transmission assembly is coupled with the driving assembly.

[0046] In use, the length of the first protrusion 602 is greater than the length of the arc-shaped rack 601, so that after the clamping block 704 is completely separated from the clamping groove 708, at this time, the umbrella gear 702 is just engaged with the arc-shaped rack 601, the umbrella gear 702 rotates 180 degrees under the meshing force of the arc-shaped rack 601, and the rotating shaft 701 synchronously rotates 180 degrees with the umbrella gear 702, and it is worth mentioning that the rotating shaft 701 is installed at the position opposite to the shaft center of the filter screen 2, so that the filter screen 2 is flipped 180 degrees with the rotating disc 1, and the impurities accumulated on the surface of the filter screen 2 and the edible oil are poured into the second receiving tray 402 together.

[0047] At the same time, after the filter screen 2 is flipped 180 degrees, the arc-shaped rack 601 is separated from the umbrella gear 702, and the second protrusion 707 is separated from the first protrusion 602, so that the clamping block 704 is quickly clamped in the clamping groove 708 under the action of the spring 706, so that the clamping block 704 is connected with the limiting block 703, and the filter screen 2 is fixed.

[0048] And, the top wall of the second receiving tray 402 is provided with a scraper (not shown in the figure), which can scrape off impurities when the filter screen 2 is flipped by 180 and the filter screen 2 moves synchronously with the rotating disc 1. The setting of the driving mechanism 6 and the transmission mechanism 7 enables the impurities falling on the surface of the filter screen 2 to be cleaned automatically, without manual cleaning, thereby saving labor.

[0049] As shown in Figure 6 , as a further scheme of the present application, the bottom of the rotating disc 1 is provided with a recess 101, which is annular in shape; the driving mechanism 6 and the transmission mechanism 7 are located at the position of the recess 101, and the driving mechanism 6 is arranged at the bottom of the transmission mechanism 7. The recess 101 enables the driving mechanism 6 and the transmission mechanism 7 to be designed in a hidden manner, making the entire device more beautiful and safe.

[0050] As shown in Figures 9 to 10 , the output shaft 501 is connected with a force storage assembly 11 outside through a speed change assembly 8; the speed change assembly 8 comprises a first gear 801, which is rotatably connected to the outside of the output shaft 501 through a one-way damping bearing, and one side of the first gear 801 is meshingly connected with a second gear 802.

[0051] In use, the output shaft 501 rotates counterclockwise to drive the first gear 801 to rotate, and the first gear 801 drives the second gear 802 to rotate. Since the first gear 801 and the second gear 802 have different numbers of teeth, the first gear 801 can drive the second gear 802 to rotate several turns after one revolution.

[0052] As a further scheme of the present application, the force storage assembly 11 comprises a sleeve 1101, which is fixedly connected to the base, and the sleeve 1101 is connected with a connecting rod 1102 through a torsional spring 1103. One end of the connecting rod 1102 is rotatably connected to the base, and the other end is fixedly connected with a cleaning brush 9. An inlet pipe 14 is arranged directly above the cleaning brush 9.

[0053] In use, the second gear 802 drives the connecting rod 1102 to rotate against the force of the torsional spring 1103, and the connecting rod 1102 drives the cleaning brush 9 to rotate. When the output shaft 501 pauses, the filter screen 2 after flipping is just moved to the upper side of the cleaning brush 9, at which time the infrared photoelectric sensor is triggered. The sensor is of the E18-D80NK type, and the inlet pipe 14 located above is opened to discharge water flow, thereby performing reverse flushing on the filter screen 2. In combination with the reverse rotation of the connecting rod 1102, the cleaning brush 9 is driven to rotate, thereby cleaning the filter screen 2 and further improving the cleaning effect.

[0054] Here, it is worth mentioning that the bottom of the rotating disc 1 is provided with three groups of first magnetic sealing rubber strips (not shown in the figure), the cross-sectional shape of the first magnetic sealing rubber strip is set as a circular ring, the diameter of the first magnetic sealing rubber strip is larger than the diameter of the filter screen 2, and the coaxial setting of the outer side of the cleaning brush 9 is provided with a circular cover plate (not shown in the figure), the circular cover plate is fixed with the outer wall of the oil receiving disc 4, both ends of the circular cover plate are provided with openings, and the top end of the circular cover plate is provided with a second magnetic sealing rubber strip, the first magnetic sealing rubber strip and the second magnetic sealing rubber strip are attracted each time the filter screen 2 is alternately replaced, and can block the splashing of water droplets when the filter screen 2 is reversely washed.

[0055] As shown in Figure 10 , the outer wall of the oil receiving disc 4 is fixedly connected with a wiping cloth 10, and the wiping cloth 10 is arranged on one side of the cleaning brush 9.

[0056] In use, the filter screen 2 after reverse washing by water flow can be naturally dried until the next time the filter screen 2 is alternately replaced, in order to further ensure that the filter screen 2 does not stay water droplets, when the filter screen 2 is replaced again, the filter screen 2 can be wiped dry by the wiping cloth 10, so as to ensure that the filter screen 2 is dry.

[0057] As shown in Figure 11 , in the present application, in order to prevent external environmental impurities from entering the rotating disc 1 and polluting the edible oil, a cover plate 12 can be arranged on the top of the rotating disc 1, and the cover plate 12 can be fixed with the oil inlet pipe 13 and the water inlet pipe 14 by bolts.
