DETAILED DESCRIPTION

[0021] In order to better understand the purpose, structure and function of the present invention, the edible oil and grease filtering device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 6As shown, an edible oil and grease filtering device of the present invention comprises a base 1, an outer barrel 2 arranged on the base 1 through legs, and an inner barrel 3 for precipitating edible oil and grease, wherein the inner barrel 3 is located in the outer barrel 2 and is arranged concentrically with the outer barrel 2. An oil filter ring 38 is also connected to the top surface of the inner barrel 3, and a filter screen 39 is provided on the inner wall of the oil filter ring 38, and the filter screen 39 is laid around the inner circle of the oil filter ring 38. Among them, the top surface of the oil filter ring 38 and the top surface of the outer barrel 2 are also connected through a top cover 11, and the top surface of the oil filter ring 38, the top surface of the top cover 11 and the top surface of the outer barrel 2 are flush. Of course, an oil outlet pipe 4 for discharging grease to the outside is also connected to the oil filter ring 38, and the oil outlet pipe 4 runs through the outer barrel 2. In order to facilitate the better discharge of the grease added to the inner barrel 3, a lifting device is provided on the outer barrel 2, and a limiting column 24 is also provided on the inner wall of the inner barrel 3, and the limiting column 24 is arranged along the axial direction of the inner barrel 3. A scraper 7 for cleaning the impurities inside the inner barrel 3 is also slidably arranged from bottom to top, and the scraper 7 is slidably arranged with the limit column 24, and at the same time, the lifting device cooperates with the scraper 7. After the grease is added to the inner barrel 3, it can be precipitated. After the impurities in the grease are precipitated, the lifting device is started, and the lifting device drives the scraper 7 to move upward, and the grease in the inner barrel 3 will also move upward under the action of the scraper 7, and the grease will be filtered again by the filter 39 when passing through the filter 39, and then flow into the oil filter ring 38 and be discharged outward through the oil outlet pipe 4. In this way, the purpose of filtering the grease can be achieved.

[0023] Specifically, the lifting device includes a first motor 5 provided on the bottom surface of the outer barrel 2, which rotates a first screw 6 provided on the outer barrel 2, the first motor 5 is connected to an external power source, and the first screw 6 penetrates the bottom surface of the inner barrel 3 and is rotatably arranged therewith, and the first screw 6 is threadedly connected to a scraper 7. When the first motor 5 is working, it drives the first screw 6 to rotate, and when the first screw 6 rotates, the scraper 7 threadedly connected to the first screw 6 begins to move upward in the inner barrel 3 under the action of the limiting column 24, and during the movement, the scraper 7 scrapes off impurities on the inner wall of the inner barrel 3 and impurities on the filter 39, thereby saving the process of manually cleaning the filter 39.

[0024] In order to facilitate the cleaning of impurities on the top surface of the scraper 7, a connecting barrel 8 is provided on the top surface of the outer barrel 2. A cover 9 is detachably provided on the top surface of the connecting barrel 8 by bolts, and a slag discharge pipe 34 is connected to the bottom surface of the connecting barrel 8. Impurities on the scraper 7 can be discharged outward through the slag discharge pipe 34. Figure 1 and Figure 2As shown, the cover 9 is also connected to an oil inlet pipe 35 for adding grease to the inner barrel 3, and a cleaning component is also provided on the cover 9, through which impurities on the scraper 7 can be cleaned, and the cleaned impurities will be transported to the connecting barrel 8 and then discharged through the slag discharge pipe 34, which saves time and effort and improves work efficiency. Specifically, the cleaning component includes a second motor 13 which is arranged on the top surface of the cover 9 and is connected to an external power supply, and rotates a rotating shaft 12 which is arranged on the cover 9. A first scraper 14 is symmetrically arranged on the rotating shaft 12 about its axis, and the first scraper 14 is located below the cover 9, and the bottom surface of the first scraper 14 is flush with the top surface of the oil filter ring 38. When the first screw 6 drives the scraper 7 to rise until its top surface is flush with the top surface of the oil filter ring 38, the first motor 5 stops working, and then the second motor 13 is started. The second motor 13 drives the first scraper 14 to start rotating through the rotating shaft 12, and the first scraper 14 will scrape off impurities on the top surface of the scraper 7 during the rotation process, and the first scraper 14 will be driven by the rotating shaft 12 to rotate at high speed, and the impurities scraped off on the first scraper 14 will be thrown onto the connecting barrel 8, thereby achieving the purpose of cleaning the impurities on the top surface of the scraper 7.

[0025] In order to prevent impurities from remaining on the first scraper 14, a push plate 17 is slidably provided on the first scraper 14 along its length direction, and a driving device for driving the push plate 17 is provided on the cover 9. The driving device can drive the push plate 17 to move on the first scraper 14, and when the push plate 17 moves, it will scrape off the impurities remaining on the first scraper 14, completing the cleaning of the first scraper 14. Figure 2 As shown, the inner bottom surface of the connecting barrel 8 is lower than the top surface of the outer barrel 2, and the inner diameter of the connecting barrel 8 is larger than the outer diameter of the outer barrel 2, so that a collecting groove 10 is formed between the inner wall of the connecting barrel 8 and the outer wall of the outer barrel 2. The impurities thrown out will remain in the collecting groove 10, and the slag discharge pipe 34 for discharging impurities is connected to the bottom surface of the collecting groove 10. At the same time, a second scraper 36 corresponding to the collecting groove 10 is also provided at the free end of the first scraper 14. The second scraper 36 will push and collect the impurities in the collecting groove 10, and discharge the impurities when they pass through the slag discharge pipe 34.

[0026] At the same time, in order to prevent impurities from adhering to the push plate 17, a support 18 is slidably provided on the fixed plate 15 at the outer end of the first scraper 14, and a first stop block 20 is provided at the top of the support 18, and a cleaning plate 19 is provided at the bottom, and a first spring 21 is sleeved on the support 18 between the first stop block 20 and the fixed plate 15. At the same time, an inclined block 23 is provided at the bottom end of the push plate 17, and the inclined block 23 cooperates with the cleaning plate 19. The driving device drives the inclined block 23 to move toward the outer end of the first scraper 14 through the push plate 17, and during the movement, the inclined block 23 will scrape off the impurities on the first scraper 14 and push them to the outside of the first scraper 14. When the inclined block 23 contacts the cleaning plate 19, the cleaning plate 19 will move downward through the inclined surface of the inclined block 23, and push the impurities scraped off by the inclined surface of the inclined block 23 downward while moving, so that the impurities on the inclined surface of the inclined block 23 are cleaned up, and the impurities are prevented from falling into the inner barrel 3 after the inclined block 23 moves to the initial position, causing pollution to the grease. The impurities cleaned by the cleaning plate 19 will fall into the collecting tank 10. When the inclined block 23 moves to the initial position, as the inclined block 23 moves away, the first spring 21 will lift the cleaning plate 19 on the support 18 to the initial position through the first limit block 20 for next use.

[0027] The driving device mentioned above includes a fixed plate 15 provided at both ends of the first scraper 14, a second screw 16 is rotatably provided on the two fixed plates 15, and the second screw 16 is threadedly connected to the push plate 17, and a third motor 22 is provided at the outer end of the second screw 16. Among them, a positive electrode ring 40 and a negative electrode ring 41 are provided on the inner wall of the connecting barrel 8, the positive electrode of the third motor 22 contacts the positive electrode ring 40, the negative electrode of the third motor 22 contacts the negative electrode ring 41, and the positive electrode ring 40 and the negative electrode ring 41 are respectively connected to the positive electrode and the negative electrode of the external power supply, so as to power the third motor 22. When the third motor 22 is working, the third motor 22 will drive the second screw 16 to rotate, and the second screw 16 will drive the push plate 17 and the inclined block 23 to move on the first scraper 14. It should be noted that the third motor 22 can rotate forward and reverse, so as to realize the forward and reverse rotation of the second screw 16, so that the push plate 17 and the inclined block 23 can reciprocate on the first scraper 14.

[0028] Preferably, a vibration device is provided in the outer barrel 2. By providing the vibration device, the inner barrel 3 can be vibrated, so that impurities on the inner wall of the inner barrel 3 fall off, and the vibration of the inner barrel 3 can also drive the filter 39 on the oil filter ring 38 to vibrate, so that impurities on the filter 39 fall off better, so that the scraper 7 scrapes the filter 39 more cleanly. Specifically, the vibration device includes a gear ring 27 rotatably arranged on the inner bottom surface of the outer barrel 2, and a plurality of protrusions 28 are distributed around the axis of the top surface of the gear ring 27, and a percussion hammer 29 is provided on each protrusion 28 to slide radially along the gear ring 27, and a limit plate is provided at the outer end of the percussion hammer 29 to prevent it from detaching from the protrusion 28. A second limit block 30 is also provided on the bottom surface of the percussion hammer 29, and a second spring 31 is provided between the second limit block 30 and the protrusion 28. At the same time, a gear 32 is rotatably provided between the top cover 11 and the inner bottom surface of the outer barrel 2, and a fourth motor 33 connected to an external power source is provided on the bottom surface of the outer barrel 2, and the gear 32 is meshed with the gear ring 27. In addition, a plurality of convex strips 25 cooperating with the striking hammer 29 are distributed on the outer peripheral wall of the inner barrel 3 along its axial direction. The operation of the fourth motor 33 will drive the gear 32 to rotate, and the gear 32 will drive the gear ring 27 meshing therewith to rotate. When the gear ring 27 rotates, the protrusion 28 arranged on the gear ring 27 will also rotate around the axis of the gear ring 27, and the knocking hammer 29 on the protrusion 28 will contact the convex strip 25 on the outer wall of the inner barrel 3 when rotating with the protrusion 28, and when touching, the knocking hammer 29 pushes the second spring 31 through the second limit block 30, and when the knocking hammer 29 disengages from the convex strip 25, the second spring 31 will push the knocking hammer 29 to knock on the inner barrel 3 through the second limit block 30, so that the inner barrel 3 vibrates, so that the impurities on the inner barrel 3 can be better detached, and the oil filter ring 38 connected to the inner barrel 3 will also vibrate, so that the impurities on the filter screen 39 can also be better removed.

[0029] As a further improvement, an electric push rod 37 is symmetrically provided at the bottom of the outer barrel 2 about its center, and a mounting ring 26 is provided between the outer barrel 2 and the inner barrel 3, and the telescopic ends of the two electric push rods 37 are connected to the mounting ring 26, and the gear ring 27 is rotatably connected to the mounting ring 26. The two electric push rods 37 are connected through a controller so that the two electric push rods 37 move at the same speed and in the same direction. When the electric push rod 37 drives the mounting ring 26 to move, the gear ring 27 and the components on the gear ring 27 set on the mounting ring 26 will also move upward, and while the electric push rod 37 is working, the fourth motor 33 continues to work, so that the knocking hammer 29 will fully knock on the outer wall of the inner barrel 3, so that the impurities on the inner barrel 3 and the impurities on the filter 39 can be better separated, and the operation is simple and convenient to use.

[0030] Method of use: Add edible oil and grease into the inner barrel 3 through the oil inlet pipe 35, then let the grease placed in the inner barrel 3 settle, and start the lifting device after settling. The lifting device drives the scraper 7 to move upward in the inner barrel 3, and when the scraper 7 moves upward, the grease in the inner barrel 3 will also rise, and when the grease level exceeds the bottom surface of the filter 39, the grease will flow through the filter 39 to the oil filter ring 38 and be discharged through the oil outlet pipe 4, thereby completing the filtering effect of the grease. Then, the scraper 7 is driven to move to the initial position through the lifting device, and then the vibration device is started. The vibration device vibrates the inner barrel 3, and the scraper 7 is driven to move upward again through the lifting device and the scraper 7 is scraped against the wall of the inner barrel 3 again. When the top surface of the scraper 7 rises to be flush with the bottom surface of the top cover 11, the second motor 13 is started, and the second motor 13 drives the first scraper 14 through the rotating shaft 12 to scrape the impurities on the top surface of the scraper 7, and then the scraped impurities will be thrown to the connecting barrel 8 while the first scraper 14 rotates. When the top surface of the scraper 7 is cleaned, the second motor 13 stops working and the third motor 22 is started. The third motor 22 drives the second screw 16, and the push plate 17 threadedly connected to the second screw 16 drives the inclined block 23 to move toward the third motor 22. The inclined block 23 scrapes the residual impurities on the first scraper 14 and pushes them into the connecting barrel 8. After the inclined block 23 contacts the cleaning plate 19, the cleaning plate 19 moves downward with the inclined surface of the inclined block 23 and pushes away the impurities on the inclined surface of the inclined block 23, thereby reducing the residual impurities on the inclined block 23. After that, the third motor 22 rotates in the opposite direction, and drives the inclined block 23 on the push plate 17 to move to the initial position through the second screw 16, and then drives the scraper 7 to move to the initial position through the telescopic device.
