[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.

DETAILED DESCRIPTION

[0021] As Figure 1 shown, a filtering device for grain oil raw material processing and production includes an oil inlet pipe 13, which is usually made of 304 food-grade stainless steel material that is resistant to high temperature and corrosion, for continuously filtering edible oil to the filtering structure. This is prior art and will not be described in detail here. The difference is that, as Figures 1 to 3 shown, it further includes an outwardly extended and flanged rotating disc 1. The bottom of the rotating disc 1 is embedded with three groups of filter screens 2, which are annularly distributed. The filter screens 2 are spaced apart from the inner bottom surface of the rotating disc 1. A flow guide groove 3 is arranged between each two adjacent groups of filter screens 2. Each two groups of filter screens 2 are communicated through the flow guide groove 3. One end of each group of flow guide grooves 3 is shallower than the other end. The bottom of the rotating disc 1 is coaxially provided with an oil receiving tray 4, which is fixed to the base and used for receiving the preliminarily filtered edible oil. The cross section of the oil receiving tray 4 is fan-shaped, and the axial center of the oil receiving tray 4 is in a fully open state. The device further includes a motor 5, the output end of which is fixedly connected with an output shaft 501, which penetrates the axial center of the oil receiving tray 4 and is fixedly connected to the bottom of the rotating disc 1.

[0022] In this embodiment, the edible oil is continuously conveyed to the filter screens 2 through the oil inlet pipe 13 for filtering. The preliminarily filtered edible oil falls into the oil receiving tray 4 at the bottom of the rotating disc 1, and the bottom of the oil receiving tray 4 is communicated with a conveying pipe, through which the edible oil can be conveyed to the next step for further processing. The conveying pipe is also made of 304 food-grade stainless steel. At the same time, the oil outlet end of the oil inlet pipe 13 is opposite to the axial center 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, which not only prevents the edible oil from splashing everywhere, but also prevents the impurities on the surface of the filter screen 2 from accumulating and causing the edible oil to overflow into the flow guide groove 3. In use, after each group of filter screens 2 is quantitatively filtered, the motor 5 is started to drive the rotating disc 1 to rotate counterclockwise, and each single rotation is 120 degrees, so that the filter screens 2 are alternately replaced. During the process of alternately replacing the filter screens 2, the edible oil continuously discharged 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 filtering. It is particularly worth mentioning that the filter screen 2 and the rotating disc 1 are coupled by a simple buckle structure (not shown in the figure). The filter screen 2 full of impurities is rotated counterclockwise by 120 degrees, moved to the position of the sector-shaped gap of the oil receiving disc 4, and then removed. After the impurities are cleaned, the filter screen 2 is installed again. This not only ensures the continuous filtering of the edible oil, but also can clean the impurities in time, thereby improving the filtering effect of the edible oil.

[0023] 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.

[0024] 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. The first receiving disc 401 is used to receive the edible oil filtered initially. The filter screen 2 full of impurities to be cleaned is rotated to be directly above the second receiving disc 402 for removal. The impurities and part of the edible oil mixed with the impurities can be poured into the second receiving disc 402. After the edible oil in this part is deposited, it can be treated separately to avoid waste of the edible oil.

[0025] As shown in Figures 4 to 8 , a transmission mechanism 7 is installed on the outer side of each group of filter screens 2. The transmission mechanism 7 includes a clamping assembly and a transmission assembly, and the transmission assembly is arranged on one side of the clamping assembly.

[0026] The clamping assembly includes a limiting block 703 fixedly connected to one end of a 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 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 on the outer side of 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 arranged as an arc surface. The cross-sectional shapes of the limiting block 703, the clamping block 704 and the clamping groove 708 are all hexagonal.

[0027] A driving mechanism 6 is installed in the second receiving disc 402. The driving mechanism 6 includes a releasing assembly, and the releasing assembly includes a first protruding block 602. One end of the first protruding block 602 is arranged as an arc surface.

[0028] The clamping assembly and the releasing assembly are coupled.

[0029] In use, the motor 5 drives the rotating disc 1 to rotate counterclockwise, the filter screen 2 rotates synchronously with the rotating disc 1, and the clamping assembly rotates synchronously with the filter screen 2 until the clamping assembly moves to the releasing assembly, at this time, the second protrusion 707 is pressed by one end of the arc surface 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 slot 708, so that the limiting block 703 loses the limiting, and then the rotating shaft 701 can rotate alone. Further, the driving mechanism 6 further comprises a driving assembly fixedly connected to one side of the releasing assembly; the driving assembly comprises an arc-shaped rack 601 fixedly connected to the inner bottom surface of the second receiving disc 402, and the first protrusion 602 is fixedly connected to one side of the arc-shaped rack 601.

[0030] The transmission assembly comprises a rotating shaft 701 fixedly connected to the outer wall of the filter screen 2, and a bevel gear 702 fixedly connected to the outer side of the rotating shaft 701.

[0031] The transmission assembly is coupled with the driving assembly.

[0032] 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 slot 708, the bevel gear 702 is just engaged with the arc-shaped rack 601, and the bevel gear 702 rotates 180 degrees under the engagement of the arc-shaped rack 601, and the rotating shaft 701 rotates 180 degrees synchronously with the bevel 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 are poured into the second receiving disc 402 together with the edible oil; At the same time, after the filter screen 2 is flipped 180 degrees, the arc-shaped rack 601 is separated from the bevel 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 slot 708 under the action of the spring 706, and the clamping block 704 is connected with the limiting block 703 to fix the filter screen 2; In addition, the top wall of the second receiving disc 402 is provided with a scraper (not shown in the figure), which can scrape off the impurities when the filter screen 2 moves synchronously with the rotating disc 1 after being flipped 180 degrees, and the impurities falling on the surface of the filter screen 2 can be cleaned automatically without manual cleaning, thereby saving labor.

[0033] As Figure 6As shown, as further schemes of the present application, the bottom of the rotating disc 1 is provided with a groove 101, the shape of the groove 101 is arranged as an annular shape; the positions of the driving mechanism 6 and the transmission mechanism 7 are located at the position of the groove 101, and the driving mechanism 6 is arranged at the bottom of the transmission mechanism 7. The groove 101 is arranged to make the driving mechanism 6 and the transmission mechanism 7 be designed in a hidden manner, so that the whole device is more beautiful and safe.

[0034] As shown, Figures 9 to 10 The outer side of the output shaft 501 is connected with the force storage assembly 11 through the speed change assembly 8; the speed change assembly 8 comprises a first gear 801, the first gear 801 is rotatably connected to the outer side of the output shaft 501 through a one-way damping bearing, and a second gear 802 is meshingly connected to one side of the first gear 801.

[0035] 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 number of teeth of the first gear 801 is different from that of the second gear 802, one rotation of the first gear 801 can drive the second gear 802 to rotate several times.

[0036] As further schemes of the present application, the force storage assembly 11 comprises a sleeve 1101, the sleeve 1101 is fixedly connected to the base, 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 the cleaning brush 9. An inlet pipe 14 is arranged above the cleaning brush 9.

[0037] 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 to rotate, the filter screen 2 after being flipped is just moved to above the cleaning brush 9 at this time, which triggers the infrared photoelectric sensor, the sensor model is E18-D80NK, and the inlet pipe 14 above is opened to discharge water flow to reversely flush the filter screen 2. Combined with the reverse rotation of the connecting rod 1102, the cleaning brush 9 is driven to rotate to clean the filter screen 2, which further improves the cleaning effect. Here, it is worth mentioning that the bottom of the rotating disc 1 is provided with three groups of first magnetic sealing strips (not shown in the figure), the cross-sectional shape of the first magnetic sealing strip is arranged as a circular ring shape, the diameter of the first magnetic sealing strip is greater than that of the filter screen 2, and a coaxial circular cover plate (not shown in the figure) is arranged outside the cleaning brush 9, the circular cover plate is fixed to the outer wall of the oil receiving disc 4, both ends of the circular cover plate are arranged as openings, and a second magnetic sealing strip is arranged at the top end of the circular cover plate. Each time the filter screen 2 is alternately replaced, the first magnetic sealing strip and the second magnetic sealing strip are attracted to each other, which can prevent water droplets from splashing everywhere when the filter screen 2 is reversely flushed.

[0038] AsFigure 10 As shown, the outer wall of the oil pan 4 is fixedly connected with a wiping cloth 10, which is arranged on one side of the cleaning brush 9.

[0039] In use, the filter screen 2 after reverse washing with water flow can be naturally dried until the next time the filter screen 2 is replaced alternately. In order to further ensure that the filter screen 2 does not stay with 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.

[0040] As shown, 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.

[0041] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
