Description

Technical Field

[0001] This utility model belongs to the technical field of animal and vegetable oil recycling, specifically relating to a filtration device for recycling waste animal and vegetable oils. Background Technology

[0002] In the recycling and processing of waste animal and vegetable oils (mainly referring to recycled cooking oil such as gutter oil), waste oil containing solid impurities (such as food scraps, bone fragments, and carbon deposits) usually enters a vertically or inclined filter frame (containing a metal filter screen) through a top feed inlet, and the impurities are filtered out by the filter frame.

[0003] Traditional fixed feed inlets cause grease and impurities to concentrate in specific areas of the filter screen (such as the center or front), resulting in underutilization of the effective filtration area (with relatively unused edge areas). This limits the equipment's processing capacity, causing impurities to quickly accumulate and compact in the concentrated areas, forming a "mud seal." This not only significantly slows down the grease penetration rate in these areas, creating a filtration bottleneck, but more importantly, it causes the filter screen in these areas to bear excessive local pressure and impact loads. Filter screens damaged due to localized stress concentration need to be replaced, thus increasing maintenance costs, energy consumption, and downtime. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for recycling waste animal and vegetable oils, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A filtration device for recycling waste animal and vegetable oils includes a material distribution component, comprising a housing, an inner feed hopper fixedly connected to the inside of the housing, a swing bucket positioned below the feed hopper, central shafts fixedly connected to both sides of the swing bucket, a filter frame positioned below the swing bucket, a discharge hopper positioned below the filter frame, and a power assembly providing power to the swing bucket positioned on the left side; and a striking component, comprising a fixed frame fixedly connected to the inside right side of the housing, a rotating rod rotatably connected inside the fixed frame, and a striking post fixedly connected to the outer side of the rotating rod away from the fixed frame.

[0006] In a preferred embodiment of this utility model, the power assembly includes a mounting frame, which is fixedly connected to the left side of the outer casing. A motor is fixedly connected to the left side of the mounting frame, a turntable is fixedly connected to the output end of the motor, and a movable column is fixedly connected to the output end of the turntable. A movable slot is provided on the left side of the swing bucket.

[0007] In a preferred embodiment of this utility model, the movable column is movably connected inside the movable groove, and both central shafts are rotatably connected inside the outer shell. The movable column is positioned at an eccentric position on the turntable.

[0008] As a preferred embodiment of this utility model, a protruding limiting ring is provided on the outer side of the turntable, and the turntable is rotatably connected to the inside of the outer shell.

[0009] As a preferred embodiment of this utility model, the filter frame has a raised center and a lower perimeter, and a leakage hole is provided inside the filter frame. The feed hopper, filter frame and discharge hopper are all fixedly connected inside the outer shell.

[0010] As a preferred embodiment of this utility model, a fixed column is fixedly connected to the right side of the swing bucket, and a slip ring is rotatably connected to the outside of both the fixed column and the striking column. A compression spring is fixedly connected between the two slip rings, and a sound insulation plate is provided on the right side of the fixed frame.

[0011] In a preferred embodiment of this utility model, the sound insulation plate is fixedly connected to the right side of the outer shell, the fixing post is located directly below the central axis, and two mounting rings are fixedly connected to the outside of both the fixing post and the striking post, and the slip ring is movably connected between the two mounting rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the set material distribution component, the power component drives the swing bucket to swing back and forth around the central axis, so that the waste oil is periodically guided to different positions above the filter frame, thereby making the waste oil and impurities more evenly spread on the entire effective area of ​​the filter frame. At the same time, the continuous swing helps to prevent impurities from forming a stable blockage layer in the filter screen area directly below the feed hopper, achieving a preliminary anti-blocking effect.

[0013] 2. The set-in striking component provides power through the swinging of the swing bucket, causing the striking column to reciprocate around the axis and strike the inner wall of the fixed frame, causing the fixed frame to vibrate. The vibration energy directly acts on the filter frame and the impurity layer on it, which helps to loosen and break the initially accumulated and compacted filter cake, release the grease channels, and thus greatly accelerate the impurity sliding process, causing the impurities to accumulate in the low-lying areas, achieving a further anti-clogging effect.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a filter device for recycling waste animal and vegetable oils, including a material distribution component and a housing 10. A feeding hopper 11 is fixedly connected inside the housing 10. A swing bucket 12 is arranged below the feeding hopper 11. A central shaft 13 is fixedly connected to both the left and right sides of the swing bucket 12. A filter frame 14 is arranged below the swing bucket 12. A discharge hopper 15 is arranged below the filter frame 14. A power component 16 that provides power to the swing bucket 12 is arranged on the left side of the swing bucket 12.

[0020] The power unit 16 drives the swing bucket 12 to swing back and forth around the central axis 13, so that the waste oil is periodically guided to different positions above the filter frame 14, thereby making the waste oil and impurities more evenly spread on the entire effective area of ​​the filter frame 14 and improving the oil penetration ability.

[0021] Furthermore, the power assembly 16 includes a mounting bracket 161, which is fixedly connected to the left side of the housing 10. A motor 162 is fixedly connected to the left side of the mounting bracket 161. A turntable 163 is fixedly connected to the output end of the motor 162. A movable column 164 is fixedly connected to the output end of the turntable 163. A movable slot 165 is provided on the left side of the swing bucket 12. The movable column 164 is movably connected inside the movable slot 165. Both central shafts 13 are rotatably connected inside the housing 10. The movable column 164 is located at an eccentric position on the turntable 163.

[0022] The eccentric setting of the movable column 164 causes the movable column 164 to rotate in a circle when the turntable 163 rotates, so that when the movable column 164 moves inside the movable groove 165, it drives the swing bucket 12 to swing around the two central axes 13.

[0023] Preferably, a raised limiting ring is provided on the outer side of the turntable 163. The turntable 163 is rotatably connected to the inside of the housing 10. The inside of the filter frame 14 is a boss-shaped structure with a high center and low periphery. The filter frame 14 has a leakage hole. The feed hopper 11, the filter frame 14 and the discharge hopper 15 are all fixedly connected to the inside of the housing 10.

[0024] It should be noted that the filter frame 14 is a raised platform shape with a high center and low periphery, which allows impurities to briefly stay in the central area before beginning to disperse and slide to the surrounding areas, thus avoiding the formation of a dense blockage core.

[0025] In use, the preheated waste animal and vegetable oils, mainly referring to recycled cooking oil such as gutter oil, are fed into the feed hopper 11 through a conveyor pipe. The waste oil falls into the swing bucket 12 under the action of the feed hopper 11. Simultaneously, the motor 162 is started, driving the turntable 163 to rotate. Because the movable column 164 is eccentrically positioned on the right side of the turntable 163, the movable column 164 rotates in a circular motion as the turntable 163 rotates. The movable column 164 moves within the movable groove 165, driving the swing bucket 12 to swing back and forth around the two central axes 13. This ensures that the waste oil inside the swing bucket 12 is evenly distributed as it swings back and forth. The waste grease is evenly distributed inside the filter frame 14, causing the landing point of the waste grease to continuously change with the oscillation. The waste grease is periodically guided to different positions above the filter frame 14, so that the waste grease and impurities are more evenly distributed over the entire effective area of ​​the filter frame 14. This significantly avoids the accumulation of impurities at a single point, and changes the stress on the filter frame 14 from highly concentrated to dynamically dispersed. The local load peak is reduced, which reduces the risk of mesh deformation, tearing or crushing, extends the life of the filter frame 14 and reduces costs. At the same time, the continuous oscillation helps to prevent impurities from forming a stable blockage layer in the filter area directly below the feed hopper 11, achieving a preliminary anti-clogging effect.

[0026] It should be further explained that the filter frame 14 has a raised platform shape with a high center and low edges. The inclined surface provides a gravity sliding channel for impurities. Under the action of gravity, most solid impurities can automatically slide along the slope to the low-lying edge. At the same time, the increased curved surface area provides more effective opening positions, improving the oil penetration capacity per unit time, which is especially advantageous when the processing volume is large. The raised platform structure itself provides an "impurity stripping channel" in the spatial direction. When impurities slide to the low-lying area, they are more likely to be removed from the central filtration area, avoiding impurities repeatedly migrating and clogging the holes under the filter screen. Most of the impurities accumulate in the low-lying area without affecting the filtration effect of other areas, thus extending the replacement cycle of the filter frame 14.

[0027] Example 2 Reference Figures 6-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a striking component, including a fixed frame 20. The fixed frame 20 is fixedly connected to the inside of the right side of the outer shell 10. A rotating rod 21 is rotatably connected inside the fixed frame 20. A striking post 22 is fixedly connected to the outer side of the end of the rotating rod 21 away from the fixed frame 20. A fixed post 23 is fixedly connected to the right side of the swing bucket 12. Slip rings 24 are rotatably connected to the outside of both the fixed post 23 and the striking post 22. A compression spring 25 is fixedly connected between the two slip rings 24. A sound insulation plate 26 is provided on the right side of the fixed frame 20.

[0028] Specifically, the sound insulation plate 26 is fixedly connected to the right side of the outer shell 10, the fixing post 23 is located directly below the central shaft 13, and the fixing post 23 and the striking post 22 are both fixedly connected to two mounting rings, and the slip ring 24 is movably connected between the two mounting rings.

[0029] In use, when the swing bucket 12 swings back and forth around the two central axes 13 under the action of the power component 16, the swing bucket 12 drives the fixed column 23 to swing around the central axis 13 with the same amplitude. A compression spring 25 is provided between the fixed column 23 and the striking column 22. When the fixed column 23 is offset under the action of the swing bucket 12, the compression spring 25 will exert a pulling force on the striking column 22 in the offset direction, thereby causing the rotating rod 21 to rotate rapidly around the axis inside the fixed frame 20 until the end of the rotating rod 21 away from the fixed column 23 strikes the inside of the fixed frame 20. Similarly, when the swing bucket 12 drives the fixed column 23 to offset to the other side, the striking column 22 will swing to the other side and strike the fixed frame. On the other side inside the fixed frame 20, the swing bucket 12 swings while the striking column 22 strikes the inside of the fixed frame 20 repeatedly, causing the fixed frame 20 to vibrate. Since the fixed frame 20 is fixed inside the outer shell 10, the fixed frame 20 drives the filter frame 14 to vibrate. The vibration energy acts directly on the filter frame 14 and the impurity layer on it, which helps to loosen and break the initially accumulated and compacted filter cake, release the grease channel, and thus greatly accelerate the impurity sliding process, so that the impurities accumulate in the low-lying areas and no impurities are left on the slope, so that the holes on the slope can continue to filter, further extending the replacement cycle of the filter frame 14. At the same time, the vibration also prevents impurities from clogging the inside of the holes.

[0030] It should be added that the design of the filter frame 14, which is high in the middle and low around the edges, allows the vibration waves to be transmitted more effectively from the center to the edge in a radial pattern. This helps to break up adhering impurities and promote their overall migration, thereby achieving a further anti-clogging effect.

[0031] It should be added that the sound insulation panel 26 prevents the noise from being transmitted when it is struck.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
