DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0044] Reference Figures 1-21 A peanut oil residue filtering device with self-cleaning function, comprising a filter cartridge 2 horizontally rotating in a box 1 and a spiral lifting plate 3 for cleaning the oil residue in the filter cartridge 2, one end of the filter cartridge 2 is a closed structure, the other end is an open structure, the closed end of the filter cartridge 2 is provided with a feed pipe, the filter cartridge 2 rotates on the surface of the feed pipe, the filter cartridge 2 is conical, and the diameter of the closed end is smaller than that of the open end, the closed end of the filter cartridge 2 is provided with an external gear ring, a motor is fixed on the side surface of the box 1, one end of the motor output shaft is fixed with a driving wheel, and the driving wheel is engaged with the external gear ring. The bottom of the box 1 is conical, which is convenient for discharging filtered peanut oil, the surface of the box 1 is fixed with a suction pump 101, the suction inlet of the suction pump 101 is communicated with the inside of the box 1, and the inside of the box 1 is fixed with a protective cover 102 for preventing peanut oil from entering the suction inlet of the suction pump 101.

[0045] It can be understood that by setting the filter cartridge 2, when filtering peanut oil, the crude oil before filtration is added to the inside of the filter cartridge 2 through the feed pipe, the peanut oil is filtered through the filter cartridge 2, and the filtered peanut oil is discharged from the bottom of the box body 1; by setting the air pump 101, thereby generating negative pressure inside the box body 1, so that the peanut oil is filtered out of the filter cartridge 2 more quickly, by setting the protective cover 102, thereby shielding the air inlet of the air pump 101, preventing the peanut oil from entering the air pump 101; the filter cartridge 2 is driven to rotate by the motor, thereby avoiding the filter cartridge 2 bottom being blocked by oil residue, at the same time, the filter cartridge 2 is conical, in the process of rotating the filter cartridge 2, the oil residue can be gradually slid to the end with larger diameter, and the oil residue is automatically discharged through the spiral lifting plate 3, avoiding the filter cartridge 2 being blocked by oil residue accumulation, avoiding the work of stopping cleaning oil residue, achieving the purpose of continuous filtering of peanut oil, improving production efficiency; at the same time, the rotating filter cartridge 2 can make the oil residue evenly stick a layer inside the filter cartridge 2, and the oil residue can be used as a filtering medium, so that the pressure inside the filter cartridge 2 is greater than the pressure inside the box body 1, maintaining the effect of negative pressure oil filtration.

[0046] Specifically, the box body 1 is fixed with a shielding cover 201, the shielding cover 201 wraps the filter cartridge 2, and the bottom of the shielding cover 201 is an open structure, and a gap is provided between the shielding cover 201 and the filter cartridge 2.

[0047] It can be understood that by setting the shielding cover 201, the majority of the area of the filter cartridge 2 is wrapped, so that the negative pressure is concentrated on the bottom of the filter cartridge 2, further improving the oil discharge efficiency of the filter cartridge 2, at the same time, by setting the gap between the filter cartridge 2 and the shielding cover 201, the peanut oil on the surface of the filter cartridge 2 can flow out along the gap.

[0048] Specifically, the spiral lifting plate 3 is located at one end of the filter cartridge 2 with larger diameter, and the spiral lifting plate 3 is rotated on the side of the box body 1 through the communication pipe 302, the spiral lifting plate 3 is conical, and the taper is the same as that of the filter cartridge 2, the surface of the spiral lifting plate 3 is provided with filter cloth 301 at intervals, the inside of the communication pipe 302 is a taper hole, and the outer diameter is smaller than the inner diameter, the surface of the communication pipe 302 is fixed with a synchronous wheel, the side of the box body 1 is fixed with a motor, one end of the motor output shaft is fixed with another synchronous wheel, and the two synchronous wheels are connected through a synchronous belt transmission.

[0049] It can be understood that by setting the spiral lifting plate 3, the spiral lifting plate 3 rotates inside the filter cylinder 2, so that the oil residue accumulated inside the filter cylinder 2 is scooped up by the edge of the spiral lifting plate 3 to the surface of the spiral lifting plate 3, and through the continuous rotation of the spiral lifting plate 3, the oil residue is lifted to the center position and discharged through the communication pipe 302, and the inside of the communication pipe 302 is a tapered hole, which is beneficial to the sliding of the oil residue; by setting the spiral lifting plate 3 as a tapered shape, on the one hand, it is suitable for the tapered structure of the filter cylinder 2, and it is more convenient to clean the oil residue; secondly, the heavier oil residue is deposited at the closed end of the spiral lifting plate 3 during rotation, and the peanut oil scooped up at the same time is discharged from the open end of the spiral lifting plate 3 during rotation, avoiding a large amount of peanut oil from being discharged from the communication pipe 302; at the same time, under the action of the filter cloth 301, the peanut oil flows downward, reducing the waste of peanut oil.

[0050] Specifically, the filter cylinder 2 is provided with a scraper 4, the scraper 4 is located at the top of the filter cylinder 2, and the scraper 4 slides in the connecting cover 401, a plurality of springs are fixed between the connecting cover 401 and the scraper 4, and the connecting cover 401 slides in one end of the box body 1 close to the spiral lifting plate 3 through the lifting assembly 5.

[0051] It can be understood that by setting the scraper 4, the lifting assembly 5 drives the scraper 4 to rise to the inner wall of the filter cylinder 2 to clean the oil residue adhered to the inner wall of the filter cylinder 2, avoiding too much oil residue affecting the filtering effect, and through the sliding of the scraper 4 in the connecting cover 401, under the action of the spring, the scraper 4 is self-adapted to the pressure of the inner wall of the filter cylinder 2, avoiding too much pressure to break the filter cylinder 2 and affecting the service life of the filter cylinder 2.

[0052] Specifically, the lifting assembly 5 includes a lifting block 501 fixed at the bottom of the connecting cover 401 and an intermittent lifting assembly 502 for intermittently sliding the lifting block 501, and the lifting block 501 vertically slides in the shell fixed inside the box body 1; The intermittent lifting assembly 502 includes a top plate 5021 vertically sliding in the shell and a first ratchet plate 5022 matched with the lifting block 501, the lower end of the top plate 5021 extends out of the bottom of the shell, and a slope matched with the spiral lifting plate 3 is arranged on the top plate 5021, the first ratchet plate 5022 horizontally slides on the side of the top plate 5021 through a slide rod, a spring is sleeved on the surface of the slide rod and used for abutting the first ratchet plate 5022 against the side of the lifting block 501, and a one-way ratchet groove is arranged on both sides of the lifting block 501, and the first ratchet plate 5022 is used for pushing the lifting block 501 to slide upward.

[0053] It can be understood that by setting the intermittent lifting assembly 502, the lifting block 501 is located at the bottom of the shell in the initial state, the scraper 4 is separated from the filter cartridge 2, and is used for accumulating the oil residue layer inside the filter cartridge 2; the edge of the spiral lifting plate 3 is pushed to slide upward, under the cooperation of the ratchet, the sliding block is driven to slide upward for a distance, after the edge of the spiral lifting plate 3 is separated from the top plate 5021, the top plate 5021 and the first ratchet plate 5022 are made to slide downward under the action of gravity, in this process, the first ratchet plate 5022 is separated from the lifting block 501 by sliding horizontally through the slide rod, and the lifting block 501 is pushed upward by the spiral lifting plate 3 for multiple times, so that the scraper 4 is abutted against the inside of the filter cartridge 2, and the accumulated oil residue layer of the filter cartridge 2 is cleaned, thereby avoiding that the oil residue layer is too thick to affect the filtering effect.

[0054] Specifically, the lifting block 501 is height-limited by the second ratchet plate 503, the second ratchet plate 503 slides on the inside of the shell through the slide rod, the second ratchet plate 503 is located on the side of the lifting block 501 away from the first ratchet plate 5022, and the surface of the slide rod is sleeved with a spring for pushing the second ratchet plate 503 to abut against the side of the lifting block 501.

[0055] It can be understood that by setting the second ratchet plate 503, after the first ratchet plate 5022 pushes the lifting block 501 to slide upward, the height of the lifting block 501 is limited by the cooperation of the second ratchet plate 503 and the lifting block 501, so as to prevent the lifting block 501 from sliding downward.

[0056] Specifically, the lifting block 501 is reset downward by two groups of guide grooves 504 and top rods 505, one of the guide grooves 504 is opened on the side of the second ratchet plate 503, the other guide groove 504 is opened on the side of the connecting plate 506, the two top rods 505 are transversely rotated on the surface of the lifting block 501, the other end of the lifting block 501 abuts against the inside of the guide groove 504, the connecting plate 506 vertically slides on the surface of the first ratchet plate 5022, and the connecting plate 506 transversely slides on the bottom of the shell. The guide groove 504 comprises a first vertical groove 5041 and a second vertical groove 5042, the first vertical groove 5041 and the second vertical groove 5042 are arranged in parallel, the depth of the second vertical groove 5042 is greater than that of the first vertical groove 5041, the bottom of the first vertical groove 5041 is provided with an inclined groove facilitating the sliding of the top rod 505 to the second vertical groove 5042, and the top of the second vertical groove 5042 is provided with an inclined groove facilitating the sliding of the top rod 505 to the bottom of the first vertical groove 5041; when the top rod 505 is located in the first vertical groove 5041, the first ratchet plate 5022 and the second ratchet plate 503 are separated from the lifting block 501; and when the top rod 505 is located in the second vertical groove 5042, the first ratchet plate 5022 and the second ratchet plate 503 cooperate with the lifting block 501.

[0057] It can be understood that, in order to form a suitable thickness of oil residue layer inside the filter cartridge 2, the scraper 4 needs to be separated from the filter cartridge 2; by setting the guide groove 504 and the top rod 505, the lifting block 501 is pushed upward again by the first ratchet plate 5022 after the scraper 4 rises to the highest position and cleans the inner wall of the filter cartridge 2. Since the scraper 4 is elastically connected with the connecting cover 401, the scraper 4 can be brought into contact with the inner wall of the filter cartridge 2, and the lifting block 501 slides upward again. At this time, the lifting block 501 drives the top rod 505 to rise to the top of the second vertical groove 5042. When the lifting block 501 slides upward, the top rod 505 enters the first vertical groove 5041 under the action of the inclined groove. Under the cooperation of the top rod 505 and the first vertical groove 5041, the first ratchet plate 5022 and the second ratchet plate 503 are pushed away from the lifting block 501 at the same time, and the height of the lifting block 501 is simultaneously released. Under the action of gravity, the lifting block 501 and the scraper 4 slide downward to the lowest position, so that the scraper 4 is separated from the inner wall of the filter cartridge 2. At this time, the top rod 505 swings again and slides from the first vertical groove 5041 to the second vertical groove 5042, preparing for the upward movement of the lifting block 501 again.

[0058] Specifically, the communication pipe 302 is communicated with the secondary filtering box 6 through the residue separation pipe 7, the secondary filtering box 6 is used for filtering the oil residue discharged from the communication pipe 302 again, two filter screens 602 are fixed in the inner wall of the secondary filtering box 6, and a partition plate 601 is fixed between the two filter screens 602. The partition plate 601 is fixed to the inner wall of the secondary filtering box 6, and the bottom of the secondary filtering box 6 is communicated with the bottom of the box body 1.

[0059] It can be understood that, by setting the secondary filtering box 6, the oil residue discharged from the communication pipe 302 falls on the surface of the filter screen 602, the peanut oil remaining in the oil residue is filtered again through the filter screen 602, and the filtered oil residue flows into the bottom of the box body 1, thereby reducing the loss of peanut oil. Since the bottom of the secondary filtering box 6 is communicated with the bottom of the box body 1, the negative pressure in the box body 1 can act on the surfaces of the two filter screens 602 at the same time, thereby improving the effect of the peanut oil penetrating downward through the filter screens 602. By setting two filter screens 602, the two filter screens 602 can be cleaned alternately, avoiding the blockage of the filter screens 602, and achieving the purpose of cleaning without stopping.

[0060] Specifically, the residue separation pipe 7 is inverted Y-shaped, two outlets at the bottom of the residue separation pipe 7 correspond to the two filter screens 602 respectively, a baffle 701 for unidirectional discharge of oil residue is rotatably arranged in the residue separation pipe 7, the baffle 701 is rotatably connected in the residue separation pipe 7, and a motor for driving the baffle 701 to rotate is fixed on the surface of the residue separation pipe 7.

[0061] It can be understood that by setting the slag pipe 7, the baffle 701 blocks one of the outlets of the slag pipe 7, so that the oil slag is discharged to the surface of one of the filter screens 602. When one of the filter screens 602 accumulates enough oil slag, the motor drives the baffle 701 to rotate and block the other outlet, so that the oil slag is discharged to the surface of the other filter screen 602, achieving the purpose of alternating discharge. After the filter screen 602 accumulates enough oil slag, stand for a period of time, so that the negative pressure and the filter screen 602 can fully filter the peanut oil in the oil slag, and then clean the oil slag on the surface of the filter screen 602.

[0062] Specifically, the two filter screens 602 are respectively provided with a cleaning assembly 8 above the filter screen 602 for cleaning oil slag. The cleaning assembly 8 includes a comb plate 801 moving above the filter screen 602 through two threaded columns 803 and a cleaning plate 802 vertically slidingly connected to the surface of the comb plate 801. The bottom of the comb plate 801 is provided with a plurality of combs, and a gap is provided between the combs and the filter screen 602 for spreading the oil slag on the surface of the filter screen 602. The cleaning plate 802 is used to block the combs and the gap for cleaning the oil slag on the surface of the filter screen 602. The threaded columns 803 are rotatably connected inside the secondary filter box 6. The threaded columns 803 are surface-threadedly connected with a moving block 804. The comb plate 801 is arranged on the surface of the moving block 804. The two threaded columns 803 are respectively fixed with synchronous wheels at one end. The two synchronous wheels are drivingly connected through a synchronous belt. The other end of one of the threaded columns 803 is fixed with a motor. The motor is fixed on the side surface of the secondary filter box 6.

[0063] It can be understood that the moving block 804 and the comb plate 801 are reciprocatingly moved above the filter screen 602 by the two threaded columns 803, so that the oil slag in the middle of the filter screen 602 is evenly spread on the surface of the filter screen 602, thereby improving the adsorption effect of the negative pressure on the filter screen 602 and the oil slag. When the filter screen 602 needs to be cleaned, the cleaning plate 802 is slid to the bottom of the comb plate 801, so that the cleaning plate 802 abuts against the surface of the filter screen 602, thereby moving the cleaning plate 802 on the surface of the filter screen 602 to clean the oil slag on the surface of the filter screen 602.

[0064] Specifically, the secondary filtering box 6 is fixed with a vertical arranged residue discharging pipe 805 on the side, the upper end of the residue discharging pipe 805 is communicated with the secondary filtering box 6, the height of the upper end of the residue discharging pipe 805 is higher than the height of the filter screen 602, the comb tooth plate 801 is rotatably connected on the surface of the moving block 804 through a rotating shaft, a transition plate is arranged between the filter screen 602 and the residue discharging pipe 805, the surface of the transition plate is arranged with an arc shape same with the rotating track of the cleaning plate 802, the surface of the partition plate 601 and the inner side of the secondary filtering box 6 are respectively arranged with a limiting groove 807 for vertically sliding the comb tooth plate 801, one end of the rotating shaft towards the limiting groove 807 is fixed with a limiting block 8071, the limiting block 8071 is slidably connected in the limiting groove 807, the limiting block 8071 is square and is provided with a round corner at four corners, one end of the limiting groove 807 towards the residue discharging pipe 805 is communicated with a movable groove 8072, the width of the movable groove 8072 is larger than the width of the limiting block 8071. The movable groove 8072 is fixed above with a rack 808 for driving the rotating shaft and the cleaning plate 802 to rotate, one end of the rotating shaft towards the limiting groove 807 is fixed with a gear 8081, when the limiting block 8071 slides into the movable groove 8072, the rack 808 is engaged with the gear 8081, the rack 808 is above the gear 8081.

[0065] It can be understood that, by arranging the residue discharging pipe 805, the cleaning plate 802 discharges the oil residue from the residue discharging pipe 805, the height of the upper end of the residue discharging pipe 805 is higher than the height of the filter screen 602, which can prevent peanut oil from flowing out of the residue discharging pipe 805; by arranging the gear 8081 and the rack 808, when the comb tooth plate 801 drives the cleaning plate 802 to approach the residue discharging pipe 805, the gear 8081 is engaged with the rack 808, which makes the cleaning plate 802 rotate in the moving process, under the assistance of the transition plate, the oil residue is pushed into the residue discharging pipe 805, then the comb tooth plate 801 and the cleaning plate 802 are moved to the end away from the residue discharging pipe 805, which is convenient for the next cleaning work; by arranging the limiting groove 807 and the limiting block 8071, when the comb tooth plate 801 and the cleaning plate 802 are above the filter screen 602, the square limiting block 8071 slides in the limiting groove 807, which limits the rotation of the rotating shaft and the comb tooth plate 801, ensuring that the comb tooth plate 801 remains vertical, when the comb tooth plate 801 and the cleaning plate 802 need to rotate, the limiting block 8071 is in the movable groove 8072, which does not affect the rotation of the rotating shaft and the comb tooth plate 801.

[0066] Specifically, the upper end of the residue discharging pipe 805 is horizontally slidably arranged with a sealing plate 806 for blocking the upper end of the residue discharging pipe 805, the upper surface of the sealing plate 806 is fixed with two moving rods 8061, the moving rods 8061 are inside the secondary filtering box 6, the height of the upper end of the moving rods 8061 corresponds to the height of the moving block 804, the top end of the moving rods 8061 is fixed with a spring for driving the sealing plate 806 to close the residue discharging pipe 805.

[0067] It can be understood that by setting the sealing plate 806, the spring pushes the sealing plate 806 to slide on the upper end of the slag discharge pipe 805, and the slag discharge pipe 805 is closed to prevent peanut oil from leaking from the slag discharge pipe 805. By setting the moving rod 8061, when it is necessary to clean the oil residue, the moving block 804 moves to the position corresponding to the movable groove 8072, at this time, the moving block 804 pushes the moving rod 8061 to slide, thereby pushing the sealing plate 806 to slide, and the upper end of the slag discharge pipe 805 is released, so that the oil residue is discharged.

[0068] Specifically, the cleaning plate 802 is provided with a sliding assembly 9 on the top for sliding on the surface of the comb plate 801, the sliding assembly 9 includes a pull block 901 fixed on the top of the cleaning plate 802 and an electric push rod 902 for driving the pull block 901 to move up and down, the electric push rod 902 is fixed on the surface of the secondary filter box 6, the lower end of the electric push rod 902 is located inside the secondary filter box 6, and a connecting block 903 matched with the pull block 901 is fixed, the pull block 901 is T-shaped, and a C-shaped through slot is formed in the bottom of the connecting block 903. The electric push rod 902 is located on the side of the secondary filter box 6 away from the slag discharge pipe 805.

[0069] It can be understood that by setting the sliding assembly 9, when it is necessary to slide the cleaning plate 802 to the bottom, the comb plate 801 drives the cleaning plate 802 to slide below the electric push rod 902, so that the pull block 901 is inserted on the surface of the connecting block 903, and the electric push rod 902 works to push the cleaning plate 802 to slide to the bottom, and then the comb plate 801 drives the cleaning plate 802 to clean the filter screen 602. During the sliding process, the pull block 901 and the connecting block 903 are naturally separated.

[0070] Specifically, the cleaning plate 802 is height-limited by a clamping assembly 904, the clamping assembly 904 includes a rocker plate 9041 rotating on the top of the cleaning plate 802 and a limiting rod 9042 fixed on the top of the comb plate 801, two insertion holes 9043 are formed on the surface of the limiting rod 9042, the rocker plate 9041 is L-shaped, the upper end of the rocker plate 9041 is close to the pull block 901, and a torsional spring is sleeved on the surface of the rotating shaft of the rocker plate 9041 for inserting the lower end of the rocker plate 9041 into the insertion hole 9043.

[0071] It can be understood that by setting the clamping assembly 904, the height of the cleaning plate 802 is limited, avoiding the cleaning plate 802 from sliding randomly on the surface of the comb plate 801; the lower end of the rocker plate 9041 is inserted into the insertion hole 9043 on the surface of the limiting rod 9042 driven by the torsional spring, thereby limiting the height of the cleaning plate 802; when the height of the cleaning plate 802 needs to be adjusted, the cleaning plate 802 moves below the connecting block 903, at this time, the connecting block 903 is located between the rocker plate 9041 and the pull block 901, the side surface of the connecting block 903 abuts against the upper end of the rocker plate 9041, the rocker plate 9041 is pushed to rotate, the rocker plate 9041 is separated from the insertion hole 9043, and the purpose of automatically releasing the limiting is achieved; the height of the cleaning plate 802 can be limited, and after the pull block 901 is separated from the connecting block 903, the lower end of the rocker plate 9041 is inserted into the insertion hole 9043 again, thereby limiting the height of the cleaning plate 802; when the lower end of the rocker plate 9041 is inserted into the upper insertion hole 9043, the cleaning plate 802 is located at the highest position, and the comb plate 801 can scrape the oil residue on the surface of the filter screen 602; when the lower end of the rocker plate 9041 is inserted into the lower insertion hole 9043, the cleaning plate 802 is located at the lowest position, and the cleaning plate 802 can clean the oil residue on the surface of the filter screen 602.

[0072] In the application, when filtering peanut oil, the crude oil before filtration is added to the inside of the filter cartridge 2 through the feed pipe, the peanut oil is filtered through the filter cartridge 2, and the filtered peanut oil is discharged from the bottom of the box body 1; at the same time, the air pump 101 works to generate negative pressure in the box body 1, so that the peanut oil is filtered out of the filter cartridge 2 more quickly. In the process of filtration, the filter cartridge 2 is driven to rotate by the motor to avoid the bottom of the filter cartridge 2 being blocked by oil residues. The rotating filter cartridge 2 can make the oil residues evenly adhere to a layer inside the filter cartridge 2. The oil residues can act as a filtering medium, so that the pressure in the filter cartridge 2 is greater than the pressure in the box body 1, thereby maintaining the effect of negative pressure oil filtration. At the same time, the filter cartridge 2 is conical, so that the oil residues can gradually slide to the end with a larger diameter during the rotation of the filter cartridge 2. By arranging the shielding cover 201, most of the area of the filter cartridge 2 is wrapped, so that the negative pressure is concentrated on the bottom of the filter cartridge 2, thereby further improving the oil discharge efficiency of the filter cartridge 2. By arranging the spiral lifting plate 3, the spiral lifting plate 3 rotates inside the filter cartridge 2, the oil residues accumulated inside the filter cartridge 2 are scooped to the surface of the spiral lifting plate 3 through the edge of the spiral lifting plate 3, and the oil residues are lifted to the center position through the continuous rotation of the spiral lifting plate 3 and discharged to the secondary filter box 6 through the communication pipe 302. During the rotation of the spiral lifting plate 3, the scraping plate 4 is intermittently pushed to the inner wall of the filter cartridge 2 by the lifting assembly 5 to clean the oil residues adhered to the inner wall of the filter cartridge 2, so as to avoid too much oil residue affecting the filtering effect. After the oil residues enter the secondary filter box 6, the moving block 804 and the comb plate 801 are driven to reciprocate above the filter screen 602 by the two threaded columns 803, so as to evenly spread the oil residues in the middle of the filter screen 602 on the surface of the filter screen 602, so that the filter screen 602 filters the peanut oil remaining in the oil residues again, and the filtered oil residues flow into the bottom of the box body 1, thereby reducing the loss of peanut oil. Since the bottom of the secondary filter box 6 is communicated with the bottom of the box body 1, the negative pressure in the box body 1 can act on the surfaces of the two filter screens 602 at the same time, thereby improving the effect of the peanut oil penetrating downward through the filter screens 602. By arranging two filter screens 602, when the oil residues on one filter screen 602 accumulate enough, the residue separation pipe 7 discharges the oil residues to the surface of the other filter screen 602. After the oil residues in the filter screen 602 are filtered clean for a period of time, the cleaning work of the filter screen 602 is carried out. When the filter screen 602 is cleaned, the sliding assembly 9 drives the cleaning plate 802 to slide to the lowermost position, so that the cleaning plate 802 abuts against the surface of the filter screen 602, thereby cleaning the oil residues on the surface of the filter screen 602 when the cleaning plate 802 moves on the surface of the filter screen 602. The oil residues are pushed into the residue discharge pipe 805 by the cleaning plate 802 and discharged, thereby achieving the purpose of automatically cleaning the oil residues.
