Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to waste oil filtering equipment and a method for preparing industrial mixed oil by utilizing waste cooking oil. Background Art

[0002] With the increasing awareness of environmental protection, the treatment of garbage has gradually improved. Kitchen waste includes discarded vegetable leaves, leftovers, and leftovers. Its main sources are restaurants, canteens, and other industries related to food processing. In the actual garbage disposal process, kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce stench. It also involves a large amount of oil pollution, which makes garbage disposal more difficult. The treatment of waste cooking oil refers to the safe and standardized collection and processing of animals and plants that are no longer suitable for consumption in life to prevent them from polluting the environment or being illegally used. Waste oil treatment is not only an environmental protection issue, but also a systematic project involving food safety, resource recycling, and other aspects. When preparing industrial mixed oil, waste cooking oil is needed, so when treating waste cooking oil, the waste oil needs to be filtered.

[0003] At present, it is inconvenient to pre-treat the waste cooking oil during traditional waste oil filtration, which causes some kitchen residues to accumulate, leading to blockage, making the oil flow not smooth enough, and affecting the normal filtration of the oil. Summary of the invention

The rotating roller is rotatably installed between the two corresponding sides of the inner wall of the frame and close to the top position. The servo motor is installed on the outside of the frame and close to the rotating roller. The output end of the servo motor is fixedly installed between the rotating roller through a coupling. A rectangular shell is fixedly installed in the middle of the outer cylindrical surface of the rotating roller. A V-shaped baffle is fixedly installed in the middle of the inner cavity of the rectangular shell. A U-shaped notch is opened at the edge of the outer side of the V-shaped baffle. The outer side of the rectangular shell and away from the rotating roller is fixedly installed with a U-shaped notch. A wire brush is fixedly installed at one end of the moving roller, and a cylinder is connected to the outside of the rectangular shell and near the rotating roller. The waste cooking oil to be treated is poured from the feed hopper to the inside of the frame. The discharge port of the feed hopper corresponds to the opening on the top of the rectangular shell, so that the waste cooking oil can enter the inside of the rectangular shell, and the V-shaped baffle is used to block large pieces of debris, so that the waste oil flows through the U-shaped notch into the rectangular shell and flows out from the cylinder, so that large pieces of debris in the waste cooking oil can be separated, thereby pre-treating the waste cooking oil; By controlling the rotation speed of the servo motor output shaft, the rotation speed of the rotating roller driving the rectangular shell can be adjusted, which is helpful for separating waste oil from large debris. A screening mechanism, which is used to screen and filter waste oil and residue, and is installed in the middle of the frame; The screening mechanism comprises a supporting leg and an arc-shaped rod, the supporting leg is installed at the side of the inner cavity of the frame, the arc-shaped rod is installed in the inner cavity of the frame and on the side away from the supporting leg, the top of the supporting leg is hinged with a guide plate, a filter is fixedly installed at the middle of the top of the guide plate, a return spring is fixedly installed between the bottom end of the arc-shaped rod and the bottom of the guide plate, a baffle is fixedly installed at the side of the top of the guide plate, and an arched bar is fixedly installed on the top of the filter and close to the rectangular shell. By rotating the output end of the servo motor, the rotating roller can be driven to rotate, so that the rectangular shell is driven to rotate together, and the wire brush can be driven to rotate in a circle by the rotation of the rectangular shell, and the residue falling on the filter can be brushed away by the rotating wire brush, so that the residue is not easy to accumulate, which is helpful for the waste oil to flow downward.

[0005] Preferably, the servo motor and the rotating roller are installed at the same height, and the rectangular shell is evenly distributed in the middle of the outer circumference of the rotating roller.

[0007] Preferably, the guide plate is installed at an angle, and the bottom end of the guide plate extends to the outside of the frame, and there are two baffles, and the two baffles are installed symmetrically along the filter.

[0008] As the rotating roller drives the rectangular shell to rotate, when the rotating roller rotates to the bottom of the notch of the rectangular shell, the large debris that has been blocked can be poured onto the filter screen to unload the large debris. As the rectangular shell continues to rotate, the large debris can be pushed toward the inclined surface of the filter screen to facilitate the rolling out of the large debris. The rectangular shell drives the wire brush to rotate in a circle to clean the remaining debris, thereby reducing the amount of debris remaining on the filter screen.

[0009] Preferably, the top of the guide plate is slidably mounted on the arc-shaped rod, and the arc-shaped rod passes through the center of the return spring.

[0010] After the waste oil flowing out of the cylinder falls onto the filter screen, the waste oil can be filtered at the second level, and the small particles carried in the waste oil can be filtered, so that the waste oil can be graded and filtered fully; When the rectangular shell is rotated, the bottom end of the rectangular shell contacts the arched bar. At this time, the arched bar is subjected to downward pressing force, and under the hinged support of the supporting legs, the guide plate drives the filter screen to rotate clockwise to adjust the angle, and the reset spring is compressed, and the arched bar at the bottom end of the rectangular shell is separated. At this time, the pressing force on the arched bar disappears, and under the elastic force of the reset spring, the guide plate drives the filter screen to rotate counterclockwise for reset. Such reciprocating screening further promotes the filtration of waste oil, and the structures are connected together by utilizing the interaction between the structures.

[0011] Preferably, an auxiliary mechanism is installed in the middle of the outer side of the rack, and the auxiliary mechanism includes a heater, the heater is installed in the middle of the outer side of the rack, a dust filter is installed at the air inlet of the outer side of the heater, a blower is installed in the middle of the top of the heater, the air outlet end of the blower is provided with a connecting pipe, the end of the connecting pipe away from the blower extends to the inside of the rack, and a flip assembly is installed at the air outlet end of the connecting pipe, the heater is used to heat the internal air, and the heated hot air is sucked out by the suction force of the blower, and the hot air is transported by the connecting pipe so that the hot air enters the main pipe and is ejected from the airway into the rack under gas pressure, so that the inside of the rack can be preheated to increase the temperature inside the rack, and the heat transfer principle can be used to increase the temperature of the waste cooking oil, thereby making the waste cooking oil sparse, which is helpful for filtering the waste cooking oil.

[0012] Preferably, the blower is installed directly above the heater, the connecting pipe is a hose, and the flapping assembly is installed inside the frame.

[0013] Preferably, the flipping assembly includes a main pipe, both ends of which are hinged between a bracket and an inner wall of a frame, an air inlet of the main pipe is communicated with an air outlet of a connecting pipe, an elastic strip is fixedly installed between the main pipe and the inner wall of the frame, a flipping tooth is fixedly installed on the outer cylindrical surface of the main pipe near the filter, an air passage is opened in the middle of the inside of the flipping tooth, and the air passage is communicated with the main pipe, and the bottom end of the flipping tooth is in contact with the inclined surface of the top of the filter, so that the debris filtered on the filter can be flipped, so that the attached debris is separated, and the residual waste oil attached to the debris is promoted to fall off, and as the guide plate drives the filter to swing back and forth, and under the rotation connection of the main pipe, the flipping tooth swings back and forth, which helps the filtered debris to roll off and discharge.

[0014] Preferably, the flipping teeth are evenly distributed on the outer circumferential surface of the main pipe, and the elastic strip is arc-shaped. As the hot air is discharged from the air outlet buckle of the air duct to the position of the filter, the discharged hot air can blow the oil film attached to the surface of the filter, so that the oil film balance can be broken, causing the oil film to rupture, thereby promoting the waste oil to flow downward and gather at the bottom of the inner cavity of the frame, and then be discharged from the oil outlet.

[0015] A waste oil filtration method for preparing industrial mixed oil using waste cooking oil comprises the following steps: Step 1: Turn on the heater and the blower to work, use the heater to heat the internal air, and use the suction force of the blower to suck out the heated hot air, and under the transportation of the connecting pipe, the hot air enters the main pipe, and under the gas pressure, it is sprayed into the rack from the airway, so as to preheat the inside of the rack; Step 2: Turn on the servo motor to work. The output end of the servo motor is rotated to drive the rotating roller to rotate. The rectangular shell is driven to rotate together, and the wire brush is driven to rotate in a circle. The residue that falls on the filter screen is brushed away by the rotating wire brush. Step 3: Pour the waste cooking oil to be processed from the feed hopper into the inside of the frame, so that the waste cooking oil can enter the inside of the rectangular shell, and use the V-shaped baffle to block large pieces of debris, so that the waste oil flows through the U-shaped gap into the rectangular shell and flows out from the cylinder, so that large pieces of debris in the waste cooking oil can be separated; Step 4: When the rotating roller rotates to the bottom of the notch of the rectangular shell, the large debris that has been blocked can be poured onto the filter screen to unload the large debris. As the rectangular shell continues to rotate, the large debris can be moved to the inclined surface of the filter screen to facilitate the rolling out of the large debris. Step 5: After the waste oil flowing out of the cylinder falls onto the filter screen, it can be filtered at the second level. The rectangular shell is rotated to press the arch bar downward, so that the guide plate drives the filter screen to rotate clockwise to adjust the angle. As the pressing force on the arch bar disappears, the guide plate drives the filter screen to rotate counterclockwise to reset under the elastic force of the reset spring, and the screening is repeated in this way. Step 6: By making the bottom end of the flipping teeth contact the inclined surface at the top of the filter, the debris filtered on the filter can be flipped to separate the debris attached together, and the filter is driven to swing back and forth by the guide plate, and the flipping teeth are reciprocated under the rotation connection of the main pipe, which helps the filtered debris to roll off and discharge; Step 7: As the hot air is discharged from the air outlet buckle of the air duct to the position of the filter, the discharged hot air can blow the oil film attached to the surface of the filter, causing the oil film to rupture, thereby promoting the waste oil to flow downward and gather at the bottom of the inner cavity of the frame, and then be discharged from the oil outlet.

[0016] The present invention provides a waste oil filtering device and method for preparing industrial mixed oil using waste cooking oil. It has the following beneficial effects: 1. The waste oil filtering equipment and method for preparing industrial mixed oil using waste kitchen oil can perform secondary filtration on the waste oil after the waste oil flowing out of the cylinder falls onto the filter screen, and the small particles of debris carried in the waste oil can be filtered out, so that the waste oil can be graded and filtered fully.

[0017] 2. The waste oil filtering equipment and method for preparing industrial mixed oil using waste cooking oil utilizes a rectangular shell to rotate, and the bottom end of the rectangular shell contacts the arched bar. At this time, the arched bar is subjected to a downward pressing force, and under the hinged support of the supporting legs, the guide plate drives the filter screen to rotate clockwise to adjust the angle. As the arched bar at the bottom end of the rectangular shell separates, the pressing force on the arched bar disappears, and under the elastic force of the reset spring, the guide plate drives the filter screen to rotate counterclockwise to reset. Such reciprocating screening further promotes the filtering of the waste oil.

[0018] 3. The waste oil filtering equipment and method for preparing industrial mixed oil using waste cooking oil utilizes the output end of the servo motor to rotate, which can drive the rotating roller to rotate, so that the rectangular shell is driven to rotate together, and the wire brush can be driven to rotate in a circle through the rotation of the rectangular shell. The rotating wire brush is used to brush away the residue that falls on the filter screen, which makes it difficult for residue to accumulate and helps the waste oil to flow downward.

[0019] Fourth, the waste oil filtering equipment and method for preparing industrial mixed oil using waste cooking oil, by using the discharge port of the feed hopper to correspond to the opening on the top of the rectangular shell, the waste cooking oil can enter the interior of the rectangular shell, and the V-shaped baffle is used to block large pieces of debris, so that the waste oil flows through the U-shaped gap into the rectangular shell and flows out from the cylinder, so that the large pieces of debris in the waste cooking oil can be separated, thereby pre-treating the waste cooking oil, and by controlling the rotation speed of the servo motor output shaft, the rotation speed of the rotating roller when driving the rectangular shell can be adjusted, which is helpful for separating the waste oil from the large pieces of debris.

[0020] 5. The waste oil filtering equipment and method for preparing industrial mixed oil using waste cooking oil, as the rotating roller drives the rectangular shell to rotate, when the rotating roller rotates to the bottom of the notch of the rectangular shell, the large pieces of debris that have been blocked can be poured onto the filter screen to unload the large pieces of debris, and as the rectangular shell continues to rotate, the large pieces of debris can be pushed to the position of the inclined surface of the filter screen, so that the large pieces of debris can be rolled out, and the rectangular shell drives the wire brush to rotate in a circle, so that the remaining debris can be cleaned, reducing the amount of debris remaining on the filter screen.

[0021] 6. The waste oil filtering equipment and method for preparing industrial mixed oil using waste cooking oil, through the suction force of the blower, sucks out the heated hot air, and under the transmission of the connecting pipe, the hot air enters the main pipe, and under the gas pressure, it is sprayed from the airway into the frame, so that the inside of the frame can be preheated, so that the temperature inside the frame is increased, and the temperature of the waste cooking oil can be increased by the principle of heat transfer, so that the waste cooking oil becomes sparse, which is helpful for filtering the waste cooking oil 7. The waste oil filtering equipment and method for preparing industrial mixed oil from waste cooking oil utilizes the bottom end of the flipping teeth to contact the inclined surface of the top of the filter screen, so as to flip the debris filtered out of the filter screen, separate the debris attached together, and promote the residual waste oil attached to the debris to fall off. As the guide plate drives the filter screen to swing back and forth, and the main pipe is rotated and connected, the flipping teeth swing back and forth, which helps the filtered debris to roll off and be discharged.

After the waste oil flowing out of the cylinder 47 falls onto the filter screen 54, the waste oil can be filtered at the second level. The rectangular shell 43 is rotated to press the arch bar 57 downward, so that the guide plate 53 drives the filter screen 54 to rotate clockwise to adjust the angle. As the pressing force on the arch bar 57 disappears, the guide plate 53 drives the filter screen 54 to rotate counterclockwise to reset under the elastic force of the reset spring 55, and the screening is repeated in this way. The bottom end of the flipping teeth 653 is in contact with the inclined surface of the top of the filter screen 54, so that the sundries filtered on the filter screen 54 can be flipped, so that the sundries attached together are separated, and the filter screen 54 is driven to swing back and forth by the guide plate 53, and the flipping teeth 653 are reciprocated under the rotation connection of the main pipe 651, so as to help the sundries filtered out roll off and be discharged; Moreover, as the hot air is discharged from the air outlet buckle of the air duct 654 to the position of the filter 54, the discharged hot air can blow the oil film attached to the surface of the filter 54, so that the oil film is broken, and the waste oil is promoted to flow downward and gather at the bottom of the inner cavity of the frame 1, and then discharged from the oil outlet 3.

10. A waste oil filtration method for preparing industrial mixed oil using waste cooking oil, characterized in that: The following steps are involved: Step 1: Turn on the heater (61) and the blower (63) to heat the internal air using the heater (61), and suck out the heated hot air through the suction force of the blower (63). The hot air is transported by the connecting pipe (64) so ​​that it enters the main pipe (651) and is ejected from the air passage (654) into the frame (1) under gas pressure, thereby preheating the interior of the frame (1); Step 2: Turn on the servo motor (42) to start working. The output end of the servo motor (42) is rotated to drive the rotating roller (41) to rotate, and the rectangular housing (43) is driven to rotate together, so that the wire brush (46) can be driven to rotate in a circle; Step 3: pouring the waste cooking oil to be processed from the feed hopper (2) into the interior of the frame (1) so that the waste cooking oil can enter the interior of the rectangular shell (43), and using the V-shaped baffle (44) to block large pieces of debris, so that the waste cooking oil flows through the U-shaped notch (45) into the rectangular shell (43) and flows out from the cylinder (47), thereby separating the large pieces of debris from the waste cooking oil; Step 4: When the rotating roller (41) rotates to the bottom of the notch of the rectangular shell (43), the large debris that has been blocked can be poured onto the filter screen (54) to discharge the large debris. As the rectangular shell (43) continues to rotate, the large debris can be moved toward the inclined surface of the filter screen (54) to facilitate the rolling and removal of the large debris. Step 5: After the waste oil flowing out of the cylinder (47) falls onto the filter screen (54), the waste oil can be filtered at the second level. The rectangular housing (43) is rotated to press the arch bar (57) downward, so that the guide plate (53) drives the filter screen (54) to rotate clockwise to adjust the angle. As the pressing force on the arch bar (57) disappears, the guide plate (53) drives the filter screen (54) to rotate counterclockwise to reset under the elastic force of the reset spring (55), and the sieving movement is repeated in this way. Step 6: The bottom end of the flipping teeth (653) is brought into contact with the inclined surface at the top of the filter screen (54) to flip the debris filtered out of the filter screen (54), so that the debris adhering to the filter screen (54) is separated. The filter screen (54) is driven to swing back and forth by the guide plate (53), and the flipping teeth (653) are rotated and connected to the main pipe (651), so that the filtered debris rolls off and is discharged. Step 7: As the hot air is discharged from the air outlet buckle of the air duct (654) toward the position of the filter (54), the discharged hot air blows the oil film attached to the surface of the filter (54) so ​​that the oil film is broken, thereby promoting the waste oil to flow downward and gather at the bottom of the inner cavity of the frame (1) and be discharged from the oil outlet (3).
