Description

Technical Field

[0001] This invention belongs to the field of kitchen waste oil pretreatment technology, and particularly relates to a kitchen waste oil cleaning device that is easy to disassemble. Background Technology

[0002] When cleaning cookware, handling leftover food scraps, and collecting waste oil in restaurant kitchens, the resulting waste oil is usually not a single oil phase medium, but a mixture of oil, water, and solids containing rice grains, vegetable scraps, meat scraps, seasoning sediments, and mud particles. Before entering subsequent storage, transportation, or reprocessing stages, it usually needs to undergo pre-filtering to reduce the occurrence of solid impurities settling, odor, and pipe blockage after entering the waste oil collection container.

[0003] In small restaurants, centralized canteens, and temporary storage points for waste oil in kitchens, the amount of waste oil is often intermittently poured and collected in short bursts due to the limited space, operating habits, and the rhythm of waste oil generation. A common treatment method is to install a fixed filter cartridge in the separation box, allowing the waste oil to enter from above and undergo initial solid-liquid separation. This type of device has a simple structure and can meet the basic needs of intercepting large particles of residue. However, kitchen waste oil has characteristics such as high viscosity, large differences in impurity particle size, and easy adhesion of soft residues. After the waste oil falls into the filter cartridge, the grease first forms an oil film on the inner wall of the filter cartridge. Larger particles such as rice grains and vegetable scraps easily adhere to the oil film and the edges of the filter holes. Seasoning powder and mud further fill the spaces between the large particles, gradually forming a composite adhesion layer.

[0004] If the filter cartridge is subjected to the impact of waste oil from above in a fixed posture for a long time, the same oil-facing area will repeatedly experience the processes of oil flushing, particle interception, grease encapsulation, and static thickening. Local deposition will be significantly faster than in other areas, and over time, scale and caking will easily form, making it difficult to clean. Summary of the Invention

[0005] The purpose of this invention is to provide a kitchen waste oil cleaning device that is easy to disassemble, in order to solve the technical problem in the prior art that when kitchen waste oil is continuously exposed to oil at a fixed filtration part, local scaling and caking easily form on the inner wall of the filter cylinder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveniently disassembled kitchen waste oil cleaning device includes: a separation tank for containing kitchen waste oil to be filtered and providing installation space for the filtration process; multiple filtration mechanisms disposed within the separation tank for solid-liquid separation of the kitchen waste oil entering the separation tank, and rotating to perform filtration tasks at different working positions; each filtration mechanism includes a filter cylinder and a sealing plate; the sealing plate is disposed at the open end of the filter cylinder, and the sealing plate can move radially back and forth along the open end of the filter cylinder to open and close the opening of the filter cylinder according to the current working position of the filter cylinder; and a rotating mechanism, which is connected to the filter cylinder... A cylinder drive connection is used to drive the filter cylinder to rotate around its own axis, thereby changing the circumferential contact area of ​​kitchen waste oil and its impurities relative to the inner wall of the filter cylinder; an intermittent mechanism is driven to multiple filter mechanisms to drive the multiple filter mechanisms to intermittently rotate within the separation box, so that the multiple filter cylinders sequentially switch filtration positions; wherein, the intermittent mechanism and the rotating mechanism cooperate to enable the filter cylinder to both rotate with multiple filter mechanisms and rotate around its own axis during the filtration process, thereby dispersing the attachment position of impurities in the oil on the inner wall of the filter cylinder.

[0008] According to some embodiments, a transfer mechanism is also installed inside the separation box. The transfer mechanism includes: a first rotating shaft, which is rotatably mounted on the separation box; and a transfer box, which is fixedly mounted on the first rotating shaft and rotatably connected to the filter cartridge.

[0009] According to some embodiments, the filtration mechanism further includes: two fixed frames, both mounted on the filter cylinder; a positive and negative screw, rotatably mounted between the two fixed frames and threadedly connected to the two sealing plates; and a first motor, fixedly mounted on the fixed frames, with its power output shaft fixedly connected to the positive and negative screw.

[0010] According to some embodiments, the intermittent mechanism includes: a mounting frame, fixedly mounted on the separation box, on which a second motor is fixedly mounted; and a second rotating shaft, fixedly mounted on the power output shaft of the second motor, on which a first actuating plate is fixedly mounted.

[0011] According to some embodiments, the intermittent mechanism further includes: a second rotating tube rotatably mounted on the mounting bracket, on which a drive disc is fixedly mounted; a drive column fixedly mounted on the drive disc; a second ratchet fixedly mounted on the drive disc; and a drive frame fixedly mounted on the first rotating shaft.

[0012] According to some embodiments, the intermittent mechanism further includes: a third rotating tube rotatably mounted on the separation box, on which a first ratchet is fixedly mounted; and a second actuating plate fixedly mounted on the second rotating shaft.

[0013] According to some embodiments, the rotating mechanism includes: a first rotating tube rotatably mounted on the separation box, on which a crown gear is fixedly mounted; a plurality of first gears, respectively fixedly mounted on a plurality of filter cartridges, and all meshing with the crown gear; a first pulley fixedly mounted on the first rotating tube; and a second pulley fixedly mounted on the first ratchet and connected to the first pulley via a drive belt.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. The transfer mechanism, intermittent mechanism and sealing plate opening and closing structure in this invention cooperate to allow multiple filtration mechanisms to enter the top oil receiving position in sequence and have the corresponding filter cylinder undertake the current filtration task. The filter cylinder that exits the top position remains closed and enters the static oil draining state, so that the waste oil input load is no longer concentrated in the fixed area of ​​a single filter cylinder for a long time, which helps to reduce the continuous accumulation of grease and solid impurities in the same inner wall position in kitchen waste oil.

[0016] 2. In this invention, the first motor drives the positive and negative screws to rotate. The positive and negative screws drive the two sealing plates to move synchronously in opposite directions, so that the top filter cylinder can form a relatively central oil receiving opening. When waste oil enters the filter cylinder, it is not easy to be biased to one side of the inner wall for a long time. Moreover, the opening can be closed in time after the filter cylinder leaves the top position, so that the filtering, waiting and oil draining states are distinguished from each other, which is conducive to improving the stability of the filtration process.

[0017] 3. After the second motor outputs in reverse in this invention, the power is transmitted to multiple filter cartridges via the second actuating plate, the first ratchet, the second pulley, the drive belt, the first pulley, the first rotating tube, the crown gear, and multiple first gears. This causes the filter cartridges to rotate around their own axes while maintaining their current working position. The contact area between waste oil and impurities and the inner wall of the filter cartridge changes accordingly, and tangential disturbance is generated on the incompletely hardened adhesion layer, which helps to reduce the probability of scaling and local hardening on the inner wall of the filter cartridge.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Example 1:

[0035] like Figures 1 to 8 As shown, a conveniently disassembled kitchen waste oil cleaning device includes a separation box 100, multiple filter mechanisms 110 disposed within the separation box 100, a rotating mechanism 130 connected to the filter mechanisms 110, and an intermittent mechanism 140 for driving the multiple filter mechanisms 110 to operate intermittently. The filter mechanism 110 includes a filter cylinder 112 and a sealing plate 111 disposed at the open end of the filter cylinder 112. The sealing plate 111 moves relative to the filter cylinder 112 to open or close the filter cylinder 112. The rotating mechanism 130 is connected to the filter cylinder 112 to drive the filter cylinder 112 to rotate around its own axis. The intermittent mechanism 140 drives the multiple filter cylinders 112 to rotate intermittently during the filtration of waste oil, so that the contact area between the inner wall of the multiple filter cylinders 112 and the impurities in the grease changes periodically, and promotes the loosening of impurities attached to the inner wall of the filter cylinders 112, thereby reducing the probability of scale and local caking on the inner wall of the filter cylinders 112 when they are fixed for a long time.

[0036] In the above structure, the separation box 100 serves as the external carrying space for the incoming kitchen waste oil. The filtration mechanism 110 is located inside the separation box 100 to intercept solid impurities in the kitchen waste oil. The filter cylinder 112 serves as the main filtration component, and its cylinder wall can be provided with filter holes or a filter screen to allow the oil phase and some liquid phase to pass through, while solid impurities such as rice grains, vegetable scraps, meat scraps, seasoning sediments, and mud are trapped inside the filter cylinder 112. The sealing plate 111 is located at the open end of the filter cylinder 112. When the filter cylinder 112 is in the oil receiving position, the sealing plate 111 is open; when the filter cylinder 112 leaves the oil receiving position, the sealing plate 111 is closed to prevent the filter cylinder 112, which is not in the oil receiving position, from continuing to receive new waste oil.

[0037] The filtration of kitchen waste oil differs from the sieving of general cleaning liquids. Grease forms a viscous boundary layer on the inner wall of the filter cylinder 112. Coarse particles are initially retained on this boundary layer, while fine particles then enter the gaps between the coarse particles, resulting in localized composite deposition. In this embodiment, a rotating mechanism 130 drives the filter cylinder 112 to rotate around its own axis, causing a circumferential change in the inner wall of the filter cylinder 112 relative to the waste oil landing point and the attached impurities. Furthermore, an intermittent mechanism 140 drives multiple filter cylinders 112 to intermittently rotate within the separation box 100, allowing different filter cylinders 112 to take turns entering the main oil-receiving area, preventing a single filter cylinder 112 from being subjected to the impact of all the waste oil for an extended period. The rotation of the filter cylinder 112 changes the circumferential oil-receiving position of its inner wall, while the intermittent rotation of multiple filter cylinders 112 changes the time sequence in which different filter cylinders 112 perform the filtration task. Combined, these two processes prevent impurities in the waste oil from being concentrated on a single inner wall area of ​​a single filter cylinder 112 for an extended period.

[0038] Because soft residues and fine deposits in the oil form clumps, a relatively stable attachment position, continuous liquid flow replenishment, and a sufficiently long settling and thickening time are required. In this embodiment, the intermittent mechanism 140 causes the position of the filter cartridge 112 to change periodically, the rotating mechanism 130 causes the contact area between the inner wall of the filter cartridge 112 and impurities in the waste oil to change periodically, and the sealing plate 111 prevents the filter cartridge 112 from receiving new waste oil when it is not in operation. All three factors work together to reduce the above-mentioned scaling conditions.

[0039] Example 2:

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: a transfer mechanism 120 is also installed inside the separation box 100. The transfer mechanism 120 includes a first rotating shaft 122 and a transfer box 121. The first rotating shaft 122 is rotatably mounted on the separation box 100, and the transfer box 121 is fixedly fitted with the first rotating shaft 122 and rotatably connected to the filter cartridge 112. The filter mechanism 110 also includes two fixing frames 113, a positive and negative screw 115, a first motor 114, and a slide rod 116. Both fixing frames 113 are mounted on the filter cartridge 112. The positive and negative screw 115 is rotatably mounted between the two fixing frames 113 and threadedly connected to the two sealing plates 111. The first motor 114 is fixedly mounted on the fixing frame 113. The power output shaft of the first motor 114 is fixedly connected to the positive and negative screw 115. The slide rod 116 is mounted on... The fixed frame 113 guides the movement direction of the sealing plate 111; the intermittent mechanism 140 includes a mounting frame 142, a second motor 143, a second rotating shaft 148, a first actuating plate 149, a second rotating tube 147, a drive disc 145, a drive column 146, a second ratchet 1492, and a drive frame 144. The mounting frame 142 is fixedly mounted on the separation box 100, the second motor 143 is fixedly mounted on the mounting frame 142, the second rotating shaft 148 is fixedly mounted on the power output shaft of the second motor 143, the first actuating plate 149 is fixedly mounted on the second rotating shaft 148, the second rotating tube 147 is rotatably mounted on the mounting frame 142, the drive disc 145 is fixedly mounted on the second rotating tube 147, the drive column 146 and the second ratchet 1492 are both fixedly mounted on the drive disc 145, and the drive frame 144 is fixedly mounted on the first rotating shaft 122.

[0041] In operation, the second motor 143 rotates in the forward direction, and its power output shaft drives the second rotating shaft 148 to rotate. The second rotating shaft 148 then drives the first actuating plate 149 to rotate around its axis. During rotation, the first actuating plate 149 matches the second ratchet 1492 and pushes it to rotate in one direction. Since the second ratchet 1492 is fixedly mounted on the drive disk 145, its rotation causes the drive disk 145 to rotate synchronously. The drive column 146 on the drive disk 145 rotates along with the drive disk 145. When the drive column 146 reaches the force-bearing part of the drive frame 144, it pushes the drive frame 144, causing it to drive the first rotating shaft 122 to rotate intermittently by ninety degrees. After the first rotating shaft 122 rotates, the intermediate box 121 rotates synchronously with the first rotating shaft 122, and the multiple filter mechanisms 110 installed on the intermediate box 121 switch positions in sequence. Preferably, the four filter mechanisms 110 switch between the top, bottom and left and right side positions respectively.

[0042] When a filter mechanism 110 is switched to the top of the transfer box 121, the first motor 114 on that filter mechanism 110 starts, and the power output shaft of the first motor 114 drives the positive and negative screws 115 to rotate. Since the threads on both sides of the positive and negative screws 115 rotate in opposite directions, after the two sealing plates 111 are threadedly engaged with the positive and negative screws 115, they cannot rotate with the positive and negative screws 115 under the guidance and restriction of the slide rod 116. They can only move in a straight line along the direction of the slide rod 116. Therefore, the two sealing plates 111 move away from each other synchronously, so that the opening end of the filter cylinder 112 is opened to receive the kitchen waste oil entering from above the separation box 100; the other three filter mechanisms 110 not at the top keep the sealing plates 111 closed, so that the corresponding filter cylinders 112 do not receive new waste oil.

[0043] This process makes the top station the sole primary oil receiving station. After the top filter cylinder 112 opens, it receives the current batch of waste oil. The oil passes through the filter holes of the filter cylinder 112 and enters the lower part of the separation box 100, where solid impurities are trapped. After the filter cylinder 112 completes filtration for a period of time, the second motor 143 drives it forward again, causing the transfer box 121 to switch to the next filtration mechanism 110. The original top filter cylinder 112 leaves the oil receiving position and closes, while a new filter cylinder 112 opens. In this way, the oil receiving process is broken down into multiple continuous but independent filtration periods. A single filter cylinder 112 is no longer in a high-load oil receiving position for extended periods, and residual grease inside can continue to drain downwards after leaving the top position.

[0044] From the perspective of solid-liquid separation, the newly trapped residue layer still contains a certain amount of oil. If it is immediately flushed by new waste oil, the residue layer will be further compacted and mixed with fine sediments, forming a more stable sludge layer. However, in this embodiment, the filter cylinder 112, which is away from the top, enters a closed and static state, allowing residual oil to precipitate out from between the particles. The residue layer no longer receives continuous replenishment of new material, and the caking rate decreases accordingly. At the same time, the positive and negative screws 115 drive the two sealing plates 111 to open symmetrically, so that the oil receiving window is relatively centered when the waste oil enters the filter cylinder 112, reducing the local impact intensity caused by unilateral flow deviation.

[0045] Example 3:

[0046] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, while other parts are the same as in Embodiment 1 or Embodiment 2, the difference between this embodiment and the above embodiments is that: the intermittent mechanism 140 further includes a third rotating tube 1493, a first ratchet 141, and a second actuating plate 1491. The third rotating tube 1493 is rotatably mounted on the separation box 100, the first ratchet 141 is fixedly mounted on the third rotating tube 1493, and the second actuating plate 1491 is fixedly mounted on the second rotating shaft 148; the rotating mechanism 130 includes a first rotating tube 133, a crown gear 131, and a plurality of first teeth. The system includes a wheel 132, a first pulley 134, a drive belt 135, and a second pulley 136. A first rotating tube 133 is rotatably mounted on the separator 100. A crown gear 131 is fixedly mounted on the first rotating tube 133. Multiple first gears 132 are fixedly mounted on multiple filter cartridges 112 and mesh with the crown gear 131. A first pulley 134 is fixedly mounted on the first rotating tube 133. A second pulley 136 is fixedly mounted on the first ratchet 141 and is connected to the first pulley 134 via the drive belt 135.

[0047] In specific operation, once the filter cartridge 112 begins to be continuously filled with waste oil, the second motor 143 rotates in the reverse direction, driving the second rotating shaft 148 to rotate in the reverse direction. At this time, the first actuating plate 149, due to the change in rotation direction, no longer pushes the second ratchet 1492, and the second ratchet 1492 does not drive the drive disc 145. The drive column 146 on the drive disc 145 also does not push the drive frame 144. Therefore, the first rotating shaft 122 and the transfer box 121 remain in their current positions, and the top filter cartridge 112 continues to stably receive waste oil. Simultaneously, the second actuating plate 1491 on the second rotating shaft 148 engages with the first ratchet 141 during its reverse rotation, driving the first ratchet 141 to rotate.

[0048] After the first ratchet 141 rotates, it drives the third rotating tube 1493 and the second pulley 136 to rotate. The second pulley 136 drives the first pulley 134 to rotate via the drive belt 135. The first pulley 134 is fixed on the first rotating tube 133, so when the first pulley 134 rotates, it causes the first rotating tube 133 to rotate synchronously. The crown gear 131 on the first rotating tube 133 rotates with the first rotating tube 133. The crown gear 131 meshes with multiple first gears 132. Since the multiple first gears 132 are respectively fixedly installed on multiple filter cartridges 112, the rotation of the multiple first gears 132 drives the multiple filter cartridges 112 to rotate around their respective axes.

[0049] The aforementioned transmission path ensures that the reverse output of the second motor 143 only drives the filter cylinder 112 to rotate, without driving the transfer box 121 to switch positions. This allows the top filter cylinder 112 to stably receive waste oil while changing the circumferential oil-receiving position on its inner wall. The waste oil no longer impacts the same area of ​​the cylinder wall, and the combined deposition of coarse and fine particles is less likely to thicken continuously in a single localized area. When the filter cylinder 112 rotates, tangential relative movement occurs between the inner wall of the filter cylinder 112 and the already attached oil residue layer. The residue layer that is not yet fully hardened is subjected to shear disturbance, making it easier for soft vegetable scraps, meat scraps, and rice grains stuck at the edges of the filter holes to loosen or redistribute, thereby reducing the probability of a hardened layer forming locally on the inner wall.

[0050] Simultaneously, the crown gear 131 meshes synchronously with multiple first gears 132, enabling multiple filter cylinders 112 to rotate simultaneously. Although the filter cylinders 112 located in non-top positions do not receive new waste oil, oil films and fine deposits may still remain on their inner walls after the previous round of filtration. Synchronous rotation allows these residues to migrate circumferentially along the cylinder wall and accumulate at lower levels under gravity, which is beneficial for continued oil drainage and reducing unilateral solidification. Thus, the station rotation in Example 2 creates a temporal dispersion of the filtration load, and the rotation of the filter cylinder 112 in Example 3 creates a spatial dispersion of the oil-receiving area on the inner wall of a single cylinder. The progressive cooperation of these two aspects ensures that the filter cylinders 112 not only receive oil in turn but also continuously change their internal contact positions during oil reception.

[0051] Working principle:

[0052] Step 1: When the equipment is in standby mode, multiple filtration mechanisms 110 are installed in the circumferential position of the transfer box 121, the first rotating shaft 122 remains stationary, the separation box 100 is in a ready state to receive kitchen waste oil, and the sealing plates 111 on multiple filter cartridges 112 can all remain closed.

[0053] Step 2: Before filtration begins, the second motor 143 starts in the forward direction. The power output shaft of the second motor 143 drives the second rotating shaft 148 to rotate. The second rotating shaft 148 drives the first actuating plate 149 to rotate. The first actuating plate 149 pushes the second ratchet 1492. The second ratchet 1492 drives the drive disc 145 and the drive column 146 to rotate synchronously.

[0054] Step 3: The drive column 146 rotates to the drive frame 144 and pushes the drive frame 144. The drive frame 144 drives the first rotating shaft 122 to rotate 90 degrees intermittently. The first rotating shaft 122 drives the transfer box 121 to rotate, so that one of the filter mechanisms 110 switches to the top oil receiving position in the separation box 100.

[0055] Step four: The filter mechanism 110 located at the top oil receiving station starts the first motor 114. The first motor 114 drives the positive and negative screws 115 to rotate. The positive and negative screws 115 drive the two sealing plates 111 to move away from each other under the guidance of the slide rod 116. The opening end of the filter cylinder 112 is opened, while the sealing plates 111 of the other filter mechanisms 110 remain closed.

[0056] Step 5: The kitchen waste oil enters the top filter cylinder 112 from the top of the separation tank 100. The oil phase and liquid phase enter the lower part of the separation tank 100 through the filter holes of the filter cylinder 112. Solid impurities such as rice grains, vegetable scraps, meat scraps, seasoning sediments and mud are trapped inside the filter cylinder 112.

[0057] Step 6: While the top filter cartridge 112 is continuously receiving waste oil, the second motor 143 switches to reverse rotation. The second motor 143 drives the second rotating shaft 148 to rotate in the opposite direction. At this time, the first actuating plate 149 does not drive the second ratchet 1492, and the drive disk 145, drive column 146, drive frame 144, first rotating shaft 122 and transfer box 121 maintain the current working position.

[0058] Step 7: When the second rotating shaft 148 rotates in the reverse direction, it drives the second actuating piece 1491 to actuate the first ratchet 141. The first ratchet 141 drives the third rotating tube 1493 and the second pulley 136 to rotate. The second pulley 136 drives the first pulley 134 to rotate through the drive belt 135. The first pulley 134 drives the first rotating tube 133 to rotate.

[0059] Step 8: The first rotating tube 133 drives the crown gear 131 to rotate, the crown gear 131 drives multiple first gears 132 to rotate, and the multiple first gears 132 respectively drive the corresponding filter cylinder 112 to rotate around its own axis, so that the top filter cylinder 112 changes the oil receiving area on its inner wall when receiving waste oil, while the non-top filter cylinder 112 continues to drain oil and loosen residual deposits in the closed state.

[0060] Step nine: When the top filter cartridge 112 reaches the set filtration period, the first motor 114 drives the forward and reverse screws 115 to rotate in the reverse direction, so that the two sealing plates 111 move closer to each other and close the opening of the current filter cartridge 112. Then the second motor 143 starts forward again, so that the transfer box 121 rotates and switches the next filtration mechanism 110 to the top oil receiving position.

[0061] Step 10: The new top filter mechanism 110 repeats the opening, oil receiving and filtering actions, while the original top filter cylinder 112 is moved to the side or bottom position and left to drain oil while the sealing plate 111 is closed, reducing the continued compaction of residual grease and solid residue inside.

[0062] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
