Description

Technical Field

[0001] The invention relates to the field of edible oil purification, in particular to a waste edible oil continuous degreasing purification system. Background Art

[0002] In order to prevent waste cooking oil from polluting the soil and water sources, it is generally degreased and purified before being discharged. Degreasing and purification of waste cooking oil can enable it to be reused, reduce the demand for fresh cooking oil, and save resources. The degreasing and purification steps of waste cooking oil generally include collection and pretreatment, alkaline washing and coagulation, static stratification, decolorization, deodorization, filtration, and oil recovery. Among them, filtration of waste cooking oil can effectively remove solid particles, suspended matter and other residues in the waste cooking oil, ensuring the smooth progress of subsequent treatment processes.

[0003] When the existing filtering device filters the waste cooking oil, the residues of different sizes in the waste cooking oil are easy to clog the filter, so that the filter needs to be stopped regularly to clean the filter, which reduces the filtration efficiency. In addition, when filtering the waste cooking oil, a multi-stage filtration method is often adopted, which means that when cleaning the filter, all the filters are usually cleaned uniformly, which easily causes the filter that can still be used to be taken out prematurely, thereby increasing the time for each cleaning and further reducing the filtration efficiency. In addition, the waste cooking oil is generally used cooking oil, so that most of the residues of the waste cooking oil are substances that can absorb oil.

[0015] 1.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0031] See also Figure 1 and Figure 2 A waste cooking oil continuous degreasing and purification system comprises a mounting cylinder 1, a fixed tube 2 is fixedly mounted coaxially inside the mounting cylinder 1, a cover plate 3 is fixedly mounted on the upper end of the mounting cylinder 1, a filtering mechanism 4 for filtering the waste cooking oil is arranged on the fixed tube 2, and a pressing mechanism 5 for pressing residues in the waste cooking oil is arranged on the mounting cylinder 1.

[0032] When the waste cooking oil needs to be filtered, the waste cooking oil is first added into the interior of the mounting cylinder 1, so that the waste cooking oil flows downward from between the mounting cylinder 1 and the fixed tube 2, and at the same time, the residue in the waste cooking oil is filtered through the filtering mechanism 4, and then the pressing mechanism 5 presses the filtered residue, and finally the filtering mechanism 4 discharges the pressed residue to the outside of the mounting cylinder 1, and at the same time, the waste cooking oil after filtration is collected at the bottom of the mounting cylinder 1 by a collecting device.

[0033] Continue reading Figure 1 and Figure 2The filtering mechanism 4 includes annular filter plates 41 arranged on the fixed tube 2 at equal intervals along the vertical direction. The annular filter plates 41 are rotatably connected to the fixed tube 2. The diameter of the sieve holes on the annular filter plates 41 gradually decreases from top to bottom. An oil baffle plate 42 is fixedly installed on the left side of the fixed tube 2 at equal intervals along the vertical direction. The oil baffle plate 42 is located on the upper part of the annular filter plate 41 at the corresponding position. A spiral plate 43 is fixedly installed on the outer side of the fixed tube 2 and between two adjacent annular filter plates 41. The left side of the spiral plate 43 is fixedly connected to the oil baffle plate 42 at the corresponding position.

[0034] Continue reading Figure 1 and Figure 2 The front and rear sides of the oil baffle plate 42 are open structures, the rear lower side of the oil baffle plate 42 is attached to the annular filter plate 41, and there is a gap between the front lower side of the oil baffle plate 42 and the annular filter plate 41. The spiral plate 43 has a front-to-back symmetrical structure, and the side of the spiral plate 43 away from the oil baffle plate 42 is higher than the side of the spiral plate 43 close to the oil baffle plate 42.

[0035] When the waste cooking oil needs to be filtered, the waste cooking oil is added between the uppermost oil baffle plate 42. The waste cooking oil flows downward under the action of gravity, so that the waste cooking oil passes through the annular filter plate 41 and flows to the inside of the lower oil baffle plate 42, and then passes through the lower annular filter plate 41 to continue to flow downward. Finally, the waste cooking oil flows from the lower annular filter plate 41 to the inside of the collecting device. When the waste cooking oil passes through the annular filter plate 41, the annular filter plate 41 separates the residue in the waste cooking oil to its upper side, so that the annular filter plate 41 performs graded filtration on the residue in the waste cooking oil.

[0036] See also Figure 1 , Figure 2 and Figure 3 The filtering mechanism 4 also includes a driving assembly 45 commonly provided on the fixed tube 2 and the mounting tube 1. The driving assembly 45 includes an end face toothed ring 451 uniformly provided inside the fixed tube 2 along the vertical direction. The end face toothed ring 451 is rotatably connected to the fixed tube 2. The end face toothed ring 451 is fixedly connected to the annular filter plate 41 at the corresponding position. Transmission rods 452 are commonly uniformly provided on the right side of the mounting tube 1 and the fixed tube 2 along the vertical direction. An active bevel gear 453 meshing with the end face toothed ring 451 is fixedly installed at one end of the transmission rod 452 close to the axis of the fixed tube 2. An executive motor 454 is fixedly installed on the right side of the upper part of the cover plate 3. A belt is commonly wound between the output shaft of the executive motor 454 and the transmission rod 452.

[0037] After the annular filter plate 41 has filtered the waste cooking oil for a period of time, the execution motor 454 is started to drive all the transmission rods 452 to rotate. The transmission rods 452 drive the end face gear ring 451 at the corresponding position to rotate through the active bevel gear 453 thereon. The end face gear ring 451 drives the annular filter plate 41 at the corresponding position to rotate, so that the annular filter plate 41 drives the filtered residue to the front part of the oil baffle plate 42, and the other parts of the annular filter plate 41 are rotated to the position of the oil baffle plate 42 by the rotating annular filter plate 41, so that the annular filter plate 41 can continue to filter the waste cooking oil.

[0038] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The pressing mechanism 5 includes a toggle assembly 53 arranged on the front side of the fixed tube 2, and the toggle assembly 53 includes a rotating tube 531 rotatably arranged on the front side of the fixed tube 2 at equal intervals along the circumference of the fixed tube 2. A sliding sleeve 532 is slidably arranged on the outer side of the rotating tube 531 along its length direction. A toggle rod for toggling and combing the residue is arranged on the outer side of the sliding sleeve 532. An L-shaped rod 533 is movably inserted into the rotating tube 531. The end of the L-shaped rod 533 away from the fixed tube 2 is rotatably connected to the sliding sleeve 532. A transmission part 534 is commonly arranged on the L-shaped rod 533 and the rotating tube 531.

[0039] See also Figure 3 , Figure 4 and Figure 5 The transmission part 534 includes a driven bevel gear 5341 fixedly mounted on one end of the rotating pipe 531 close to the axis of the fixed pipe 2. The driven bevel gear 5341 is meshed with the end face gear ring 451. A follower groove plate 5432 is fixedly mounted inside the end face gear ring 451. The follower groove plate 5432 is provided with a flower-shaped groove. The vertical section of the L-shaped rod 533 slides on the flower-shaped groove of the follower groove plate 5432.

[0040] When the annular filter plate 41 drives the residue thereon to rotate toward the front of the oil baffle plate 42, the end face gear ring 451 simultaneously drives the driven bevel gear 5341 to rotate, and the driven bevel gear 5341 drives the sliding sleeve 532 to rotate synchronously through the rotating pipe fitting 531, so that the sliding sleeve 532 combs and moves the residue on the upper side of the annular filter plate 41 through the lever thereon, so that the residue can be spread flat on the annular filter plate 41, and at the same time, the end face gear ring 451 drives the follower groove plate 5432 to rotate synchronously, and the follower groove plate 5432 pushes and pulls the L-shaped rod 533 reciprocatingly along its radial direction through the flower-shaped groove thereon, and the L-shaped rod 533 drives the sliding sleeve 532 to move back and forth, so that the sliding sleeve 532 moves the residue back and forth through the lever thereon, thereby increasing the degree of spreading of the residue on the annular filter plate 41, and then continues to rotate the annular filter plate 41 intermittently.

[0041] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 The pressing mechanism 5 also includes a plurality of groups of upper clamping plates 51 and lower clamping plates 52 which are arranged at equal intervals in the vertical direction on the right side of the front part of the mounting cylinder 1. The upper clamping plates 51 and the lower clamping plates 52 are slidably connected with the mounting cylinder 1 in the vertical direction. The upper clamping plates 51 and the lower clamping plates 52 are respectively located on the upper and lower sides of the annular filter plate 41 at corresponding positions. A plug column for inserting into the sieve hole of the annular filter plate 41 is fixedly installed on the upper side of the lower clamping plate 52. A power component 54 for driving the upper clamping plates 51 and the lower clamping plates 52 to squeeze the residue is provided on the mounting cylinder 1.

[0042] See also Figure 1 , Figure 6 and Figure 7 The power assembly 54 includes a No. 1 baffle member 541 fixedly installed on the right outer side of the upper clamping plate 51, and a No. 2 baffle member 542 fixedly installed on the left outer side of the lower clamping plate 52. The No. 1 baffle member 541 and the No. 2 baffle member 542 are arranged alternately up and down, all No. 1 baffle members 541 are fixedly connected together by support rods, and all No. 2 baffle members 542 are fixedly connected together by guide rods. A push spring is arranged between the No. 1 baffle member 541 and the mounting tube 1, and a No. 1 hydraulic rod 543 is fixedly installed on the upper part of the uppermost No. 1 baffle member 541, and the telescopic section of the No. 1 hydraulic rod 543 is fixedly connected to the uppermost No. 2 baffle member 542.

[0043] When the annular filter plate 41 drives the residue spread thereon to move to the position of the upper clamp plate 51 and the lower clamp plate 52, the telescopic section of the No. 1 hydraulic rod 543 is contracted, so that the No. 1 hydraulic rod 543 drives the uppermost No. 1 baffle member 541 and the uppermost No. 2 baffle member 542 to approach each other, and the uppermost No. 1 baffle member 541 drives all the No. 1 baffle members 541 to approach the No. 2 baffle member 542 at the corresponding position, and the elastic force of the push spring pushes the No. 1 baffle member 541 upward, so that the position of the No. 1 baffle member 541 does not move, and the No. 1 hydraulic rod 543 drives the No. 2 baffle member 542 to move upward.

[0044] When the No. 2 baffle member 542 moves upward, it drives the lower clamp plate 52 to move upward synchronously, so that the lower clamp plate 52 fits against the lower side of the annular filter plate 41 at the corresponding position. At the same time, the plug posts on the lower clamp plate 52 extend into the sieve holes of the annular filter plate 41, thereby blocking the sieve holes through the plug posts. On the one hand, the plug posts can push out the residues blocked inside the sieve holes to clean and dredge the annular filter plate 41. On the other hand, the plug posts can fill the sieve holes of the annular filter plate 41, thereby preventing the upper clamp plate 51 from squeezing the residues into the inside of the sieve holes, thereby ensuring the squeezing effect of the residues.

[0045] When the lower clamping plate 52 is attached to the annular filter plate 41, the telescopic section of the No. 1 hydraulic rod 543 continues to contract. Since the lower clamping plate 52 cannot continue to move upward, the No. 1 hydraulic rod 543 drives the upper clamping plate 51 to move downward and compresses the push spring, so that the upper clamping plate 51 squeezes the residue on the annular filter plate 41, and the waste edible oil squeezed out of the residue flows downward from the annular filter plate 41 to the spiral plate 43, and then the squeezed waste edible oil flows along the spiral plate 43 to the inside of the lower oil baffle plate 42, so that the squeezed waste edible oil continues to participate in the filtration until the waste edible oil flows out of the lowest annular filter plate 41, and then the telescopic section of the No. 1 hydraulic rod 543 is extended, so that the upper clamping plate 51 and the lower clamping plate 52 return to their initial positions one by one, and then the annular filter plate 41 continues to rotate intermittently.

[0046] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 The pressing mechanism 5 also includes a plurality of groups of left clamping plates 55 and right clamping plates 56 which are evenly spaced along the vertical direction at the rear of the fixed tube 2. A moving assembly 57 for driving the left clamping plates 55 and the right clamping plates 56 to squeeze the residue is provided on the mounting cylinder 1. The moving assembly 57 includes sliding grooves 571 which are evenly spaced along the vertical direction at the rear side of the fixed tube 2. The middle part of the sliding groove 571 is a horizontal structure, and both sides of the sliding groove 571 are opening structures which gradually expand from bottom to top. The left clamping plates 55 and the right clamping plates 56 on one side close to the fixed tube 2 slide on the sliding groove 571 through a protruding column.

[0047] See also Figure 1 , Figure 8 and Fig. 9 A plurality of groups of upper arc bars 572 and lower arc bars 573 are arranged at equal intervals in the vertical direction on the rear side of the mounting cylinder 1. The upper arc bars 572 and the lower arc bars 573 are arranged alternately up and down. The upper arc bars 572 are connected to the right clamping plate 56 at the corresponding position for vertical sliding movement, and the lower arc bars 573 are connected to the left clamping plate 55 at the corresponding position for vertical sliding movement. A fixing rod 574 is fixedly installed on the right side of all the upper arc bars 572, and a connecting rod 575 is fixedly installed on the left side of all the lower arc bars 573. An L-shaped slide plate 576 is provided on the upper part of the cover plate 3 for forward and backward sliding movement, and a bidirectional hydraulic rod 577 is fixedly installed on the lower part of the vertical section of the L-shaped slide plate 576. The two telescopic sections of the bidirectional hydraulic rod 577 are hinged to the connecting rod 575 and the fixing rod 574 respectively.

[0048] In the initial state, the right clamp plate 56 and the left clamp plate 55 are respectively located on the opening structures on both sides of the sliding groove 571 at the corresponding positions, so that the right clamp plate 56 and the left clamp plate 55 are far away from each other, and at this time, there is a certain gap between the lower side surfaces of the right clamp plate 56 and the left clamp plate 55 and the annular filter plate 41, so that the annular filter plate 41 can drive the residue to move between the right clamp plate 56 and the left clamp plate 55.

[0049] When the annular filter plate 41 drives the residue squeezed by the upper clamp plate 51 and the lower clamp plate 52 to move between the left clamp plate 55 and the right clamp plate 56, the two telescopic sections of the two-way hydraulic rod 577 are contracted at the same time, so that the two-way hydraulic rod 577 simultaneously drives the connecting rod 575 and the fixed rod 574 to approach each other, and the connecting rod 575 and the fixed rod 574 drive all the upper arc bars 572 and all the lower arc bars 573 to rotate close to each other, so that the upper arc bar 572 drives the right clamp plate 56 to rotate to the left, and the lower arc bar 573 drives the left clamp plate 55 to rotate to the right.

[0050] When the right clamping plate 56 and the left clamping plate 55 rotate, they move along the trajectory of the sliding groove 571, so that the right clamping plate 56 and the left clamping plate 55 first move downward along the opening structure on both sides of the sliding groove 571. When the lower sides of the right clamping plate 56 and the left clamping plate 55 are attached to the annular filter plate 41, the right clamping plate 56 and the left clamping plate 55 rotate along the horizontal section of the sliding groove 571, so that the right clamping plate 56 and the left clamping plate 55 clamp and squeeze the residue therebetween in a horizontal direction, and then squeeze the residue in another direction, further improving the oil pressing effect and ensuring the purification output of waste cooking oil. Subsequently, the two telescopic sections of the two-way hydraulic rod 577 are extended to drive the right clamping plate 56 and the left clamping plate 55 to return to the initial position, and then the annular filter plate 41 continues to rotate intermittently.

[0051] See also Figure 1 and Fig.10 The filtering mechanism 4 also includes a slag discharge assembly 44 arranged at the rear left side of the mounting cylinder 1. The slag discharge assembly 44 includes a scraper plate 441 arranged at equal intervals at the rear left side of the mounting cylinder 1 in the vertical direction. The lower side of the scraper plate 441 is attached to the upper side of the annular filter plate 41 at the corresponding position. A support plate 442 is fixedly installed on the side of the scraper plate 441 away from the mounting cylinder 1. An electric push rod 443 is fixedly installed at the rear left side of the mounting cylinder 1, and the telescopic section of the electric push rod 443 is fixedly connected to the support plate 442.

[0052] When the annular filter plate 41 drives the residue after pressing to move to the position of the scraper plate 441, the telescopic section of the electric push rod 443 is extended to drive the support plate 442 to move in the direction away from the axis of the mounting tube 1, so that the support plate 442 drives all the scraper plates 441 to move synchronously, so that the scraper plate 441 pushes the residue after pressing on the annular filter plate 41 to the outside of the mounting tube 1, thereby cleaning the residue in time and ensuring that the annular filter plate 41 can be reused.

[0053] When filtering waste cooking oil, the present invention also includes the following steps: the first step is to add the waste cooking oil between the uppermost oil baffle plates 42, so that the waste cooking oil passes through the annular filter plate 41 and flows to the inside of the lower oil baffle plate 42, and the annular filter plate 41 separates the residue in the waste cooking oil to its upper side, so that the annular filter plate 41 performs graded filtration on the residue in the waste cooking oil.

[0054] The second step is to start the execution motor 454 to drive the annular filter plate 41 to rotate, so that the annular filter plate 41 drives the filtered residue to the front of the oil baffle plate 42, and the other parts of the annular filter plate 41 are rotated to the position of the oil baffle plate 42 by the rotating annular filter plate 41, so that the annular filter plate 41 can continue to filter the waste cooking oil.

[0055] In the third step, the end face tooth ring 451 drives the sliding sleeve 532 to comb and move the residue on the upper side of the annular filter plate 41 through the lever thereon, so that the residue can be spread flat on the annular filter plate 41. At the same time, the L-shaped rod 533 is pushed and pulled reciprocatingly along its radial direction, so that the sliding sleeve 532 can move the residue back and forth through the lever thereon, thereby increasing the degree of spreading of the residue on the annular filter plate 41, and then the annular filter plate 41 continues to be rotated intermittently.

[0056] The fourth step is to retract the telescopic section of the No. 1 hydraulic rod 543 so that the lower clamping plate 52 fits against the lower side of the annular filter plate 41 at the corresponding position. At the same time, the plug posts on the lower clamping plate 52 extend into the sieve holes of the annular filter plate 41. Then, the No. 1 hydraulic rod 543 drives the upper clamping plate 51 to move downward and squeeze the residue on the annular filter plate 41, and then continues to rotate the annular filter plate 41 intermittently.

[0057] The fifth step is to simultaneously contract the two telescopic sections of the bidirectional hydraulic rod 577 to drive the right clamping plate 56 to rotate to the left and the left clamping plate 55 to rotate to the right. When the right clamping plate 56 and the left clamping plate 55 rotate, they move along the trajectory of the sliding groove 571, so that the right clamping plate 56 and the left clamping plate 55 can clamp and squeeze the residue therebetween in a horizontal direction, and then continue to rotate the annular filter plate 41 intermittently.

[0058] In the sixth step, the telescopic section of the electric push rod 443 is extended to drive all the scraper plates 441 to move synchronously, so that the scraper plates 441 push the residue after squeezing on the annular filter plate 41 to the outside of the mounting cylinder 1, so as to clean the residue in time and ensure that the annular filter plate 41 can be reused. Then, the annular filter plate 41 is rotated intermittently and the first to sixth steps are repeated to continuously filter the waste cooking oil.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
