Description

Technical Field

[0001] The invention belongs to the technical field of grain and oil production, and specifically relates to a filtering device for grain and oil production and a filtering method thereof. Background Art

[0002] In the production process of grain and oil, it is necessary to filter impurities in grain and oil to ensure the purity and quality of grain and oil, so the demand for grain and oil filtering devices is particularly important. There are only two types of existing filtering devices. One is pure mechanized filtering, which can indeed greatly filter out impurities in grain and oil, but has a greater impact on the quality of grain and oil and cannot ensure the original color and aroma of grain and oil. The second is semi-manual filtering, which can greatly ensure the original color and aroma of grain and oil, has high quality, and is widely used in various fields; however, the grain and oil filtering devices currently used have a long oil filtering time, and impurities in grain and oil are easy to precipitate and clog the filter net, resulting in low oil filtering efficiency, and manual disassembly of the oil filtering device for cleaning will affect the continuity of production and increase time and cost;

[0003] Chinese patent CN211562036U discloses an oil filter device for grain and oil production, including a filter tank, the outer surface of the filter tank is fixedly connected with an oil inlet pipe near the upper end, the outer surface of the filter tank is located below the oil inlet pipe and fixedly installed with a booster pump, the center of the upper end cover of the filter tank is movably installed with a motor, and the output shaft of the motor penetrates into the filter tank, the output shaft of the motor is movably connected with a rotating seat, the inside of the filter tank is fixedly installed with a filter screen near the lower end, the filter screen is located in the horizontal direction of the inner surface of the filter tank and has a slag discharge port, the lower end surface of the filter tank is fixedly connected with an oil outlet pipe, and the middle end of the oil outlet pipe is fixedly connected with an oil drain pipe. It can stir the grain and oil to be filtered to prevent impurities in the grain and oil from precipitating and clogging the filter screen, clean the impurities on the filter screen, thereby improving the efficiency of oil filtering, and can also pressurize the filter tank to accelerate the oil filtering speed, further improving the oil filtering efficiency.

[0004] The inventors found that this filtering method still relies on gravity filtration. Such filtration will have the problem of decreased filtration efficiency as the amount of filtered impurities increases. In addition, as the amount of impurities increases, the internal impurities cannot be cleaned up in a timely and effective manner, which will also lead to a decrease in the overall filtration efficiency.

[0017] A filtering method of a filtering device for grain and oil production, using the filtering device for grain and oil production, comprises the following steps:

[0018] S1 connects and fixes the filter tube to the discharge pipe. When filtering and separation is required, the discharge pipe is opened, and the material in the tank enters the filter tube through the discharge pipe and flows through the guide holes to the filter screen plate for filtering and separation;

[0019] During the filtering process, S2 controls the filter press plate to periodically move up and down. Since the sealing plate is rotatable, when the filter press plate moves upward, the sealing plate automatically rotates downward due to pressure to open, allowing the material to automatically pass through the diversion hole. When the filter press plate moves downward, the sealing plate automatically seals the diversion hole, so that the filter press plate can form a sealed plate body, filter the impurities above the filter screen plate, and quickly separate the material in the tank body from the tank body, preventing the impurities on the filter screen plate from affecting the filtering efficiency.

[0020] S3 When the impurities on the filter screen plate accumulate to a certain extent, the filter press plate is located at the bottom, and then the regulating block is controlled to move upward, driving the filter screen plate to move upward, so that the filter screen plate and the filter press plate are clamped, and the liquid in the impurities is separated more thoroughly;

[0021] After S4 filtration is completed, the filter screen is controlled to move downward until the impurities on the filter screen are separated from the filter tube, and then the filter screen is controlled to rotate 180 degrees so that the impurities on the surface of the filter screen automatically fall off and separate.

[0022] Compared with the prior art, the present invention has the following technical effects:

[0023] The design of the filter press plate, guide hole, sealing plate and filter screen plate, through the rotatable sealing plate and the guide hole, enables the material to move to the filter screen plate through the guide hole when the tank is discharging normally, and to be filtered and separated by the filter screen plate. The filter press plate can move up and down, which can further improve the discharge efficiency of the material in the tank by means of pressure filtration, effectively preventing the problem of decreased filtration efficiency due to increased impurities at the filter screen plate, improving the overall filtration and separation efficiency, and thus improving the overall production efficiency;

[0024] The adjusting block can move up and down and the adjusting shaft can rotate. The up and down movement of the adjusting block can not only realize a more thorough pressure filtration separation of the material, but also the downward movement of the adjusting block can realize the separation of the filter plate and the filter tube, so that the impurities are separated from the filter tube. At the same time, with the rotation of the adjusting shaft, the filter plate can be rotated to automatically separate the impurities on the surface of the filter plate.

[0043] Example 1, please refer to Figure 1 , Figure 4 and Figure 5 , a filtering device for grain and oil production, applied to the discharge end of a filter tank, the filter tank comprising a tank body 2, a feed pipe 22 and a discharge pipe 26, the impurity filtering device comprising a filter tube 1, a filter screen plate 13 and a filter press plate 16, the feed end of the filter tube 1 is fixedly connected to the discharge pipe 26, the filter press plate 16 slides and is sealed with the inner wall of the filter tube 1, the filter press plate 16 can be moved up and down in the filter tube 1, and a plurality of guide holes are provided on the filter press plate 16, a rotatable sealing plate for sealing the guide holes is provided at the bottom of the guide holes, a symmetrically distributed and up and down movable adjustment block 12 is provided below the filter tube 1, the filter screen plate 13 is arranged at the bottom of the filter tube 1, and the filter screen plate 13 slides and is sealed with the filter tube 1, a rotatable adjustment shaft 14 is provided on the adjustment block 12, and the adjustment shaft 14 is fixedly connected to the filter screen plate 13. A rotatably connected connecting shaft is provided between one end of the sealing plate and the guide hole, and a torsion spring is provided on the connecting shaft for driving the sealing plate to automatically rotate and seal the guide hole.

[0044] The design of the filter press plate 16, the guide hole, the sealing plate and the filter screen plate 13, through the rotatable sealing plate, cooperates with the guide hole, so that when the tank body 2 is normally discharged, the material can move to the filter screen plate 13 through the guide hole, and is filtered and separated by the filter screen plate 13, and the filter press plate 16 can move up and down, which can further improve the discharge efficiency of the material in the tank body 2 by means of pressure filtration, effectively prevent the problem of decreased filtration efficiency due to increased impurities in the filter screen plate 13, and improve the overall filtration and separation efficiency;

[0045] The up and down movement of the adjusting block 12 and the rotation of the adjusting shaft 14 can not only achieve a more thorough pressure filtration separation of the material through the up and down movement of the adjusting block 12, but also achieve the separation of the filter screen plate 13 and the filter tube 1 through the downward movement of the adjusting block 12, so that impurities are separated from the filter tube 1, and at the same time, cooperate with the rotation of the adjusting shaft 14 to enable the filter screen plate 13 to automatically separate impurities on the surface of the filter screen plate 13 by rotating.

[0046] In this example, see Figure 1 The bottom of the filter tube 1 is provided with a fixedly connected and symmetrically distributed guide plate 15, the adjusting shaft 14 is provided with a fixedly connected gear 141, the bottom of the guide plate 15 is provided with a rack 151 meshing with the gear 141, and the bottom of the filter tube 1 is provided with a symmetrically distributed and fixedly connected first hydraulic rod 11, and the first hydraulic rod 11 is fixedly connected to the adjusting block 12.

[0047] The design of the rack 151 and the gear 141 can utilize the rack 151 to drive the rotation of the gear 141, thereby realizing the rotation of the filter plate 13 and the automatic recovery after rotation; the design of the first hydraulic rod 11 realizes the up and down movement control of the adjustment block 12.

[0048] In this example, see Figure 1 , Figure 2 and Figure 3 The adjusting block 12 is provided with an adjusting hole 121, and the adjusting shaft 14 is rotatably connected with the corresponding adjusting hole 121. The side wall of the adjusting hole 121 is provided with an adjusting groove 122 which is connected and penetrates outward. A first pressing and telescopic mechanism 124 which is fixedly connected is provided in the adjusting groove 122. A first pressing rod 123 is provided at the pressing end of the first pressing and telescopic mechanism 124, and a clamping rod 125 is provided at the telescopic end of the first pressing and telescopic mechanism 124. The end of the clamping rod 125 is hemispherical. A clamping groove 142 which is clamped with the clamping rod 125 is provided on the adjusting shaft 14. A retractable ejector rod 152 which is used to squeeze the pressing rod is provided on the adjusting plate. An ejector groove 153 is provided on the adjusting plate. A slidingly connected ejector rod 152 is provided in the ejector groove 153, and an ejector spring 154 which is used to drive the ejector rod 152 to automatically pop out is provided in the ejector groove 153. The end of the ejector rod 152 is hemispherical.

[0049] The design of the ejector rod 152, the ejector spring 154, the first pressing and retracting mechanism 124, the engaging rod 125 and the engaging groove 142 enables the ejector rod 152 to press the first pressing rod 123 when the gear 141 moves downward to the rack 151. Through the characteristics of the first pressing and retracting mechanism 124, the engaging rod 125 can automatically shrink, thereby releasing the fixation of the adjusting shaft 14. At this time, the gear 141 can realize automatic rotation under the action of the rack 151, and when the gear 141 moves upward and passes through the ejector rod 152, the ejector rod 152 can press the first pressing rod 123 again, thereby automatically extending the engaging rod 125 and engaging the engaging rod 125 with the engaging groove 142, thereby realizing the fixation between the adjusting block 12, the adjusting shaft 14 and the filter screen plate 13, so that the filter screen plate 13 can enter the filter tube 1 more accurately. The hemispherical design of the ejection spring 154 and the ejection rod 152 enables the ejection rod 152 to better and automatically press the first pressing rod 123 .

[0050] In this example, see Figure 4 , Figure 7 and Fig. 9The filter press plate 16 includes a central circular plate 164, an intermediate ring plate 160 and an outer ring plate 161. The central circular plate 164, the intermediate ring plate 160 and the outer ring plate 161 are rotatably and sealedly connected. There are multiple guide holes that are centrally symmetrically distributed on the intermediate ring plate 160, and the cross-section of the guide holes is inclined.

[0051] The design of the rotating and sealed connection between the center circular plate 164, the middle ring plate 160 and the outer ring plate 161, combined with the design of the inclined cross-section of the guide hole, can drive the middle ring plate 160 to rotate when the material passes through the guide hole. This design can effectively prevent impurities from accumulating on the surface of the middle ring plate 160.

[0052] In this example, see Figure 4 The filter tube 1 is provided with a plurality of filter press rods 162 that can move up and down, the filter press plate 16 is fixedly connected to the center circular plate 164, and the filter press plate 16 is provided with a scraper 163 that is fixedly connected and used to scrape impurities on the surfaces of the intermediate ring plate 160 and the outer ring plate 161. The addition of the scraper 163 can further prevent the accumulation of impurities on the surface of the filter press plate 16.

[0053] In this example, see Figure 5 , Figure 6 , Figure 7 and Figure 8 A rotatable stirring shaft 23 is provided in the middle of the tank body 2, and a fixedly connected supporting base 25 is provided at the bottom of the tank body 2, the stirring shaft 23 is rotatably connected to the supporting base 25, a discharge hole connected to the discharge pipe 26 is provided in the middle of the supporting base 25, and a plurality of discharge troughs connected to the discharge hole are provided on the side wall of the supporting base 25, a discharge plate 251 which can move up and down and is used for sealing the discharge trough is provided in the discharge trough, a plurality of rotating grooves 231 are provided on the stirring shaft 23, and stirring rods 24 are provided in each of the rotating grooves 231, and the stirring A rotating shaft 241 is provided at one end of the rod 24 and is rotatably connected to the rotating groove 231. A driving groove 232 is provided in the middle of the stirring shaft 23. The driving groove 232 is connected to the rotating groove 231, and a plurality of driving blocks 235 that can move up and down synchronously are provided in the driving groove 232. The driving blocks 235 are provided with a plurality of fixedly connected and bendable connecting members 242, and the connecting members 242 are fixedly connected to the ends of the corresponding stirring rods 24. The filter press rod 162 is movably and sealedly connected to pass through the support base 25 and is fixedly connected to the corresponding driving block 235. Among them, a compressible sealing rubber 234 is provided at the inlet of the rotating groove 231, and the sealing rubber 234 is connected and sealed to the stirring rod 24. A recovery groove is provided at the bottom of the discharging groove, and the discharging plate 251 is slidably and sealedly connected to the recovery groove. A third hydraulic rod 261 is provided in the recovery groove for driving the discharging plate 251 to move up and down.

[0054] The up and down movement of the driving block 235, in conjunction with the stirring rod 24, the connecting piece 242 and the rotating shaft 241, can realize that the stirring rod 24 can rotate around the rotating shaft 241 while rotating with the stirring shaft 23. Such a design can effectively prevent impurities in the grain and oil from being deposited in the tank body 1, thereby making it difficult to clean. At the same time, the driving block 235 is fixedly connected to the filter press rod 162, so that the driving block 235 can also drive the filter press rod 162 to move up and down while moving up and down, thereby realizing the automatic up and down movement of the filter press plate 16.

[0055] In this example, see Figure 7 , Figure 8 The driving groove 232 is prismatic, the driving block 235 is slidably connected to the driving groove 232, a driving rod 233 is provided in the middle of the driving groove 232, the bottom of the driving rod 233 is fixedly connected to the support base 25, a through-type reciprocating thread 236 groove is provided in the middle of the driving block 235, a plurality of reciprocating threads 236 are provided on the driving rod 233, and the driving rod 233 is connected to the driving block 235 by the connection method of the reciprocating thread 236, a driving motor 21 is provided at the upper end of the tank body 2, and the output end of the driving motor 21 is connected to the stirring shaft 23.

[0056] The design of the driving rod 233 and the reciprocating thread 236 enables the rotating shaft 241 to drive the driving block 235 to rotate around the driving rod 233 while rotating, thereby achieving synchronous up and down movement of multiple driving blocks 235 through the characteristics of the reciprocating thread 236.

[0057] In this example, see Figure 7 , Figure 8 and Fig. 9The filter press rod 162 includes a first rod 1621 and a second rod 1622. The first rod 1621 is fixedly connected to the corresponding driving block 235, and the second rod 1622 is fixedly connected to the middle circular plate. A first groove 1623 slidably connected to the first rod 1621 is provided in the middle of the second rod 1622. A symmetrically distributed second groove 1624 is provided on the side wall of the first groove 1623. A matching and slidably connected slider is provided in the first groove 1623. The slider is provided with a protrusion slidably connected to the second groove 1624. A limiting groove 1625 is provided on the inner wall of one of the second grooves 1624. The slider is A fixing groove 1628 corresponding to the limiting groove 1625 is provided on the side of the second slot 1624, and a second pressing and telescopic mechanism 1627 is fixedly connected in the fixing groove 1628. A limiting rod 1626 fixedly connected and used for engaging the limiting groove 1625 is provided at the telescopic end of the second pressing and telescopic mechanism 1627. A third groove 1629 penetrating and connected to the fixing groove 1628 is provided on the side wall of the second slot 1624. A second pressing rod 1620 fixedly connected is provided at the pressing end of the second pressing and telescopic mechanism 1627. A plurality of second hydraulic rods for squeezing the corresponding second pressing rods 1620 are provided in the driving groove 232. The first pressing and telescopic mechanism 124 and the second pressing and telescopic mechanism 1627 both adopt the pressing and telescopic mechanism in the existing field of press-type ballpoint pens, and this pressing and telescopic mechanism is a prior art, so this application does not describe it in detail.

[0058] The design of the first rod 1621, the second rod 1622, the second pressing and telescopic mechanism 1627, the limiting groove 1625, the third groove 1629 and the second hydraulic rod can realize the selective engagement connection between the limiting rod 1626 and the limiting groove 1625 by pressing the second hydraulic rod on the second pressing rod 1620. This design realizes the selective sliding connection between the first rod 1621 and the second rod 1622. When the filter press is not needed, the limiting rod 1626 is driven to separate from the limiting groove 1625 by pressing the second pressing rod 1620, so that the first rod 1621 and the second rod 1622 can be realized. 1621 and the second rod 1622 are slidably connected. At this time, the up and down movement of the driving block 235 will only drive the up and down movement of the first rod 1621 in the second rod 1622, and will not drive the up and down movement of the filter press plate 16, thereby reducing the overall energy consumption; and when filtering is needed, it is only necessary to press the second pressing rod 1620 again to make the limiting rod 1626 automatically pop out and engage and fix with the limiting groove 1625. At this time, the up and down movement of the driving block 235 can drive the first rod 1621 and the second rod 1622 to move up and down synchronously, thereby realizing the synchronous movement of the filter press plate 16.

[0059] When this embodiment is used:

[0060] First, the material is fed into the tank body 2, and the driving motor 21 is controlled to drive the stirring shaft 23 to rotate. The rotation of the stirring shaft 23 can drive the stirring rod 24 to rotate synchronously. Since the driving rod 233 is fixedly connected to the supporting base 25, the driving block 235 rotates synchronously with the stirring shaft 23 around the driving rod 233. Under the action of the reciprocating thread 236, multiple driving blocks 235 synchronously and periodically move up and down. When the driving block 235 moves downward, under the transmission of the connecting piece 242, the lever principle is used to realize the synchronous upward rotation of the stirring rod 24. When the driving block 235 moves upward, the stirring rod 24 will automatically rotate downward due to gravity. In this way, the stirring rod 24 can be more fully stirred for the material in the tank body 1, and the impurities in the grain and oil are effectively prevented from being precipitated and accumulated inside the tank body due to standing still.

[0061] When the driving block 235 is controlled to reach the set position, the driving motor 21 is stopped. At this time, the limiting groove 1625 is aligned with the fixing groove 1628. The second hydraulic rod is first controlled to pass through the third groove 1629 to press the second pressing rod 1620, so that the limiting rod 1626 is engaged and fixed with the limiting groove 1625. Then, the stirring shaft 23 is controlled to rotate. Then, the third hydraulic rod 261 is controlled to drive the discharge plate 251 to open the discharge groove. The material enters the discharge pipe 26 through the discharge hole, and then enters the filter tube 1, and moves to the filter screen plate 13 through the guide groove on the filter tube 1.

[0062] As the stirring shaft 23 continues to rotate, the driving block 235 also synchronously drives the filter press rod 162 to move up and down synchronously, so that the filter press rod 162 drives the filter press plate 16 to move up and down periodically, and cooperates with the guide hole, thereby realizing the rapid separation of impurities by means of filter pressing, which not only improves the discharge rate of the material in the tank body 2, but also improves the filtration efficiency of the filter screen plate 13, and can also effectively prevent the filter screen plate 13 from being blocked, resulting in a decrease in the overall filtration efficiency;

[0063] After filtering on the filter screen 13 for a certain period of time, the drive motor is turned off first, and the discharge plate 251 closes the discharge slot, and then the first hydraulic rod 11 is controlled to drive the filter screen 13 to move downward, until the gear 141 is meshed with the rack 151, and the ejector rod 152 automatically presses the first pressing rod 123, so that the engaging rod 125 is separated from the engaging groove 142, and the connection between the adjustment block 12 and the adjustment shaft 14 is released. Then, as the filter screen 13 continues to move, under the action of the gear 141 and the rack 151, Automatic rotation, so that the impurities on the surface of the filter screen plate 13 automatically fall and separate; after the impurities fall, the filter screen plate 13 moves upward, and when it moves to the ejection rod 152 again, it can drive the engaging rod 125 to engage with the engaging groove 142, thereby realizing the connection and fixation between the adjustment block 12 and the adjustment shaft 14. Therefore, with the continuous contraction of the first hydraulic rod 11, the filter screen plate 13 can be connected and fixed to the filter tube 1 again, and then the discharge plate 251 can open the discharge trough, and then the driving motor is controlled to drive the stirring shaft 23 to rotate, and the subsequent filter pressing can continue.

[0064] Since the length of the filter press rod 162 is fixed, when the content of impurities is small, the first hydraulic rod 11 can be controlled to drive the filter screen plate 13 to move upward, so that the liquid in the impurities can be better and more thoroughly filtered and separated;

[0065] When the filtration is not needed, the driving block 235 is first controlled to reach the set position and stop, so that the limit groove 1625 is aligned with the fixed groove 1628. At this time, the second hydraulic rod is first controlled to pass through the third groove 1629 to press the second pressing rod 1620, so that the limit rod 1626 is engaged and separated from the limit groove 1625, and the subsequent stirring of the material in the tank body 2 can be carried out. At this time, the rotation of the stirring shaft 23 will not drive the filter press plate 16 to move up and down;

[0066] A filtering method of a filtering device for grain and oil production, using the filtering device for grain and oil production, comprises the following steps:

[0067] S1 connects and fixes the filter tube 1 to the discharge pipe 26. When filtering and separation is required, the discharge pipe 26 is opened, and the material in the tank body 2 enters the filter tube 1 through the discharge pipe 26 and flows through the guide holes to the filter screen plate 13 for filtering and separation;

[0068] S2 controls the filter press plate 16 to periodically move up and down during filtering. Since the sealing plate is rotatable, when the filter press plate 16 moves upward, the sealing plate automatically rotates downward due to pressure to open, so that the material automatically passes through the guide hole. When the filter press plate 16 moves downward, the sealing plate automatically seals the guide hole, so that the filter press plate 16 can form a sealed plate body, filter the impurities above the filter screen plate 13, so that the material in the tank body 2 can be quickly separated from the tank body 2, and prevent the impurities on the surface of the filter screen plate 13 from affecting the filtering efficiency.

[0069] S3 When the material in the tank body 2 is completely discharged, the filter press plate 16 is located at the bottom, and then the regulating block 12 is controlled to move upward, driving the filter screen plate 13 to move upward, so that the filter screen plate 13 and the filter press plate 16 are clamped, and the liquid in the impurities is separated more thoroughly;

[0070] After the filtration is completed in S4, the filter screen plate 13 is controlled to move downward until the impurities on the filter screen plate 13 are separated from the filter tube 1, and then the filter screen plate 13 is controlled to rotate 180 degrees so that the impurities on the surface of the filter screen plate 13 automatically fall off and separate.
