Description

Technical Field

[0001] The present invention relates to the technical field of oil fuel, in particular to an oil fuel purification device. Background Art

[0002] Biomass energy resources include crop straw and agricultural processing residues, firewood and forestry processing residues, livestock manure, industrial organic wastewater and waste residues, urban domestic waste and energy plants, which can be converted into a variety of terminal energy sources such as electricity, gas fuel, solid fuel and liquid fuel. Among them, biomass liquid fuel (biofuel) has received the most attention.

[0003] For example, publication number CN216378081U discloses a device for purifying oil fuel, comprising a purification box, a stirring mechanism provided on one side of the outer wall of the purification box, the stirring mechanism comprising a motor and a second rotating shaft, the second rotating shaft being rotatably connected to one side of the purification box, and a stirring blade being fixedly connected to the outer wall inside the purification box, the top of the purification box being connected in sequence to a feed pipe and a first exhaust pipe, the side of the purification box being connected to a liquid outlet pipe, a plurality of heating rods being fixedly installed on both sides of the inner wall of the purification box, the motor being fixedly installed on one side of the outer wall of the purification box, and a U-shaped tube being fixedly connected to the output end, the top of the U-shaped tube being fixedly connected to the first rotating shaft, and the outer wall of the top end of the first rotating shaft being sleeved with a first bevel gear. The utility model improves the heating effect of the oil raw material, thereby improving the oil purification rate, and solves the problem of low purification efficiency of traditional devices.

[0004] By relying on heating to cause water droplets to settle or evaporate, only large water particles (>50μm) can be separated, and emulsions or tiny water droplets cannot be processed. Therefore, the accuracy of water separation is poor, and the purification effect is poor. Water in the fuel may cause corrosion to metal pipes, reactors or instruments (for example, dissolved oxygen in boiler water accelerates corrosion), thereby shortening equipment life and increasing maintenance costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a purification device for oil fuel in view of the above-mentioned deficiencies in the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a purification device for oil and fat fuel, including a purification box, a separation drum is provided on the top of the purification box, a feeding pipe is provided on the top of the separation drum, a discharge pipe is provided on the top of the separation drum, a suction pump is provided on the outside of the discharge pipe, an oil-water separation mechanism is provided inside the purification box, the oil-water separation mechanism includes a motor, the motor is fixedly connected to the left side of the purification box, the output end of the motor is fixedly connected to a first rotating rod through a coupling, the first rotating rod movably passes through the purification box and extends into the interior thereof, the right end of the first rotating rod is fixedly connected to a cam, the interior of the purification box is fixedly connected to a vertical plate, the vertical plate The top is fixedly connected to a limit frame, and the interior of the limit frame is slidably connected to a slide, the right side of the slide is fixedly connected to a square frame, and a hydrophilic membrane is provided inside the square frame. The left side of the slide is fixedly connected to two fixed rods, and the two fixed rods are in contact with the cam. The motor is started, and the motor drives the first rotating rod to rotate. When the first rotating rod rotates, it drives the cam to rotate. When the cam rotates, it contacts the fixed rod, thereby pushing the fixed rod to move back and forth. When the fixed rod moves back and forth, it drives the slide to move back and forth. The back and forth movement of the slide can drive the square frame to move back and forth, so it drives the hydrophilic membrane to shake back and forth. This shaking can make the oil-water mixture fully contact the hydrophilic membrane, effectively separating tiny water droplets and emulsions.

[0007] Preferably, a sliding groove is provided on the inner wall of the square frame, and a first slider is slidably connected to the inside of the sliding groove. The back of the first slider is fixedly connected to a first resistance rod, and the first resistance rod is movable through the square frame and extends outward. The first resistance rod contacts the inner wall of the purification box, and a seal is provided between the first resistance rod and the square frame.

[0008] Preferably, a partition is provided inside the chute, a first spring is fixedly connected between the partition and the first slider, a push plate is fixedly connected to the right side of the first slider, and the push plate contacts the hydrophilic membrane. When the square frame rocks back and forth, it will interfere with the first interference rod, so the first interference rod drives the first slider to move back and forth inside the chute, thereby driving the push plate to move back and forth. The forward and backward movement of the push plate can stir the fuel in the square frame. This stirring action can make the fuel fully contact with the hydrophilic membrane, avoid local accumulation or stratification of the fuel in the square frame, thereby increasing the probability of contact between water and the hydrophilic membrane, and thus improving the purification effect of the oil fuel.

[0009] Preferably, a waste separation mechanism is provided inside the separation drum, and the waste separation mechanism includes a connecting plate, which is fixedly connected to the top of the purification box, and the right side of the connecting plate is rotatably connected to a second rotating rod, and the first rotating rod and the second rotating rod are connected by a pulley set. A third rotating rod passes through the interior of the separation drum and extends to its bottom, and the third rotating rod and the second rotating rod are connected by a gear set.

[0010] Preferably, the top of the third rotating rod is fixedly connected to a rotating drum, the top of the rotating drum is fixedly connected to a connecting pipe, the bottom of the connecting pipe is hollowed out, and the outer wall of the connecting pipe is fixedly connected to a plurality of discs. When the first rotating rod rotates, it drives the second rotating rod to rotate through a pulley set, and when the second rotating rod rotates, it drives the third rotating rod to rotate through a gear set. When the third rotating rod rotates, it drives the rotating drum inside the separation drum to rotate. When the rotating drum rotates, it drives the discs to rotate through the connecting pipe. The rotation of the discs generates centrifugal force, which throws the waste residue in the grease to the outer edge of the disc and eventually deposits it in the collection tank. The rotation of the discs not only achieves centrifugal separation of the waste residue, but also provides power for the upward flow of fuel. Guided by the discs, the fuel flows upward and eventually flows into the interior of the square frame through the action of the suction pump, ensuring smooth flow of the fuel and avoiding poor fuel flow caused by blockage of waste residue.

[0011] Preferably, a collecting groove is provided on the inner bottom side of the separation drum, and a vertical groove is provided on the inner wall of the separation drum, and a second slider is slidably connected to the inside of the vertical groove, and a second spring is provided between the second slider and the inner wall of the vertical groove, and a pressure plate is fixedly connected to the right side of the second slider, and a protrusion is fixedly connected to the top of the pressure plate, and the outer wall of the disc is fixedly connected to a push rod, and when the disc rotates, it drives the push rod to rotate, and when the push rod rotates, it will contact the protrusion, and the protrusion moves downward under the action of the push rod, thereby driving the pressure plate to move downward, and the waste residue is filtered. When the push rod is out of contact with the protrusion, the pressure plate will automatically reset under the action of the second spring. The filtering effect of the pressure plate can prevent the waste residue from accumulating too high in the collecting tank and flowing back into the fuel, thereby ensuring the purity and quality of the fuel, and avoiding problems such as reduced purification effect and equipment corrosion caused by the backflow of waste residue.

[0012] Preferably, a decolorization mechanism is provided inside the purification box, comprising an activated carbon cartridge, a discharge pipe being provided on the front of the activated carbon cartridge, a fourth rotating rod being rotatably connected to the inner wall of the purification box, a swing plate being fixedly connected to the outer wall of the fourth rotating rod, a torsion spring being provided on the outer wall of the fourth rotating rod, a second interference rod being fixedly connected to the bottom of the square frame, the second interference rod being in contact with the swing plate, and when the square frame moves back and forth, the second interference rod is driven to move, and the swing plate is rotated under the dual action of the interference of the second interference rod and the torsion spring, and the swing plate is caused to rotate by the swinging of the swing plate, so that the activated carbon spraying device can release the activated carbon in different directions and positions, thereby achieving a more uniform distribution. This helps ensure that the fuel in the entire purification box is in full contact with the activated carbon, thereby improving the decolorization effect.

[0013] Preferably, the bottom of the square frame is fixedly connected to a folding plate, the top of the folding plate is fixedly connected to a rack, the inner bottom side of the purification box is fixedly connected to a fixed plate, the internal rotation of the fixed plate is connected to a fifth rotating rod and extends to its left and right sides, the outer wall of the fifth rotating rod is fixedly connected to a stirring plate, the outer wall of the fifth rotating rod is fixedly connected to a first gear, the first gear and the rack are meshed with each other, when the square frame moves back and forth, it will drive the folding plate to move, the folding plate will drive the rack to move, and the first gear will rotate under the driving action of the rack, thereby driving the fifth rotating rod inside it to rotate, thereby driving the stirring plate to rotate, and the stirring plate in the purification box can make the oil and activated carbon fully contact, improve the decolorization efficiency, ensure the uniformity of the decolorization effect, and further improve the quality of the oil fuel.

[0014] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This oil fuel purification device pushes the hydrophilic membrane within the square frame to continuously vibrate. This vibration enables the oil-water mixture to fully contact the hydrophilic membrane, effectively separating tiny water droplets and emulsions. This solves the problem that traditional heating methods can only separate large particles of water but cannot handle emulsions or tiny water droplets. It greatly improves the accuracy of water separation, and the forward and backward movement of the push plate can stir the fuel within the square frame. This stirring action enables the fuel to fully contact the hydrophilic membrane, preventing localized accumulation or stratification of the fuel within the square frame, thereby increasing the probability of water contact with the hydrophilic membrane and improving the purification effect of the oil fuel.

[0015] 2. This grease fuel purification device generates centrifugal force through the rotation of the disc, which flings waste residue from the grease toward the outer edge of the disc, where it is ultimately deposited in a collection tank. This centrifugal separation method efficiently separates waste residue from the fuel, effectively removing these impurities and improving fuel purity. The pressure filtering action of the pressure plate also prevents waste residue from accumulating excessively in the collection tank and flowing back into the fuel, ensuring fuel purity and quality while avoiding problems such as reduced purification efficiency and equipment corrosion caused by waste residue backflow.

[0016] 3. This oil fuel purification device contains activated carbon in an activated carbon cartridge, which absorbs pigments in oils and fats, thereby decolorizing the oils and fats. The swinging plate allows the activated carbon spray device to release the activated carbon in different directions and positions, achieving a more even distribution. This helps ensure that the fuel in the entire purification tank is fully in contact with the activated carbon, improving the decolorization effect. Furthermore, the stirring plate's movement within the purification tank ensures full contact between the oil and the activated carbon, increasing decolorization efficiency and ensuring uniform decolorization, further enhancing the quality of the oil and fuel.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-9One embodiment of the present invention is: a purification device for oil fuel, including a purification box 1, a separation drum 2 is provided on the top of the purification box 1, a feeding pipe 3 is provided on the top of the separation drum 2, a discharge pipe 4 is provided on the top of the separation drum 2, a suction pump 5 is provided on the outside of the discharge pipe 4, an oil-water separation mechanism 6 is provided inside the purification box 1, the oil-water separation mechanism 6 includes a motor 611, the motor 611 is fixedly connected to the left side of the purification box 1, the output end of the motor 611 is fixedly connected to the first rotating rod 612 through a coupling, the first rotating rod 612 The movement passes through the purification box 1 and extends into the interior thereof. The right end of the first rotating rod 612 is fixedly connected to a cam 613. The interior of the purification box 1 is fixedly connected to a vertical plate 614. The top of the vertical plate 614 is fixedly connected to a limit frame 615. The interior of the limit frame 615 is slidably connected to a slide 616. The right side of the slide 616 is fixedly connected to a square frame 617. The interior of the square frame 617 is provided with a hydrophilic membrane 618. The left side of the slide 616 is fixedly connected to two fixed rods 624. The two fixed rods 624 are in contact with the cam 613. The motor 611 is started, and the motor 611 drives The first rotating rod 612 is driven to rotate, and the first rotating rod 612 rotates, and the cam 613 rotates. When the cam 613 rotates, it contacts the fixed rod 624, thereby pushing the fixed rod 624 to move back and forth. When the fixed rod 624 moves back and forth, it drives the slide plate 616 to move back and forth. The back and forth movement of the slide plate 616 can drive the square frame 617 to move back and forth, so it drives the hydrophilic membrane 618 to shake back and forth. This shaking can make the oil-water mixture fully contact the hydrophilic membrane 618, effectively separating tiny water droplets and emulsions. The square frame 617 The inner wall is provided with a chute 619, and a first slider 620 is slidably connected to the inside of the chute 619. The back of the first slider 620 is fixedly connected to a first resistance rod 621. The first resistance rod 621 movably penetrates the square frame 617 and extends outward. The first resistance rod 621 contacts the inner wall of the purification box 1. The first resistance rod 621 and the square frame 617 are sealed. A partition is provided inside the chute 619. A first spring 622 is fixedly connected between the partition and the first slider 620. A push plate 623 is fixedly connected to the right side of the first slider 620. The push plate 623 contacts the hydrophilic membrane 618. When the square frame 617 shakes back and forth, it will contact the first resistance rod 621. Therefore, the first resistance rod 621 will drive the first slider 620 to move back and forth inside the chute 619, thereby driving the push plate 623 to move back and forth. The forward and backward movement of the push plate 623 can stir the fuel in the square frame 617. This stirring action can make the fuel fully contact with the hydrophilic membrane 618, avoid local accumulation or stratification of the fuel in the square frame 617, thereby increasing the probability of contact between water and the hydrophilic membrane 618, and thus improving the purification effect of the oil fuel.

[0021] Working principle: Start the motor 611, and the motor 611 drives the first rotating rod 612 to rotate. When the first rotating rod 612 rotates, it drives the cam 613 to rotate. When the cam 613 rotates, it contacts the fixed rod 624, thereby pushing the fixed rod 624 to move back and forth. When the fixed rod 624 moves back and forth, it drives the slide plate 616 to move back and forth. The back and forth movement of the slide plate 616 can drive the square frame 617 to move back and forth, so it drives the hydrophilic membrane 618 to rock back and forth. This rocking can make the oil-water mixture fully contact the hydrophilic membrane 618, effectively separating tiny water droplets and emulsions. When the square frame 617 rocks back and forth, it will contact the first resistance rod 621, so it will drive the first slider 620 to move back and forth inside the slide groove 619 through the first resistance rod 621, thereby driving the push plate 623 to move back and forth, and the fuel in the square frame 617 can be stirred by the back and forth movement of the push plate 623. This stirring action can make the fuel fully contact with the hydrophilic membrane 618, avoid local accumulation or stratification of the fuel in the square frame 617, thereby increasing the probability of contact between water and the hydrophilic membrane 618, and thus improving the purification effect of the oil fuel.

[0022] See also Figure 1-9On the basis of the above embodiment, in another embodiment of the present invention, a waste residue separation mechanism 7 is provided inside the separation drum 2, and the waste residue separation mechanism 7 includes a connecting plate 711, which is fixedly connected to the top of the purification box 1, and the right side of the connecting plate 711 is rotatably connected to the second rotating rod 712, and the first rotating rod 612 and the second rotating rod 712 are connected by a pulley group. A third rotating rod 713 passes through the interior of the separation drum 2 and extends to its bottom, and the third rotating rod 713 is connected to the second rotating rod 712 by a gear group. The top of the third rotating rod 713 is fixedly connected to a rotating cylinder 714, and the top of the rotating cylinder 714 is fixedly connected to a connecting pipe 715, and the bottom of the connecting pipe 715 is hollow. It is configured that a plurality of discs 716 are fixedly connected to the outer wall of the connecting tube 715.

When the second rotating rod 712 rotates, the third rotating rod 713 will be driven to rotate through the gear group. When the third rotating rod 713 rotates, the rotating cylinder 714 inside the separation drum 2 will be driven to rotate. When the rotating cylinder 714 rotates, the disc 716 will be driven to rotate through the connecting tube 715. The rotation of the disc 716 generates centrifugal force, which throws the waste residue in the grease to the outer edge of the disc 716 and finally deposits it in the collection tank 717. The rotation of the disc 716 not only realizes the centrifugal separation of the waste residue, but also provides power for the upward flow of the fuel. The fuel flows upward under the guidance of the disc 716, and finally flows into the interior of the square frame 617 through the action of the suction pump 5, ensuring the smooth flow of the fuel and avoiding the poor flow of the fuel caused by the blockage of the waste residue. A collecting groove 717 is provided on the inner bottom side of the separation drum 2, and a vertical groove 718 is provided on the inner wall of the separation drum 2.

The outer wall of the disc 716 is fixedly connected to the push rod 72 2. When the disc 716 rotates, it drives the push rod 722 to rotate. When the push rod 722 rotates, it will contact the protrusion 721. The protrusion 721 moves downward under the action of the push rod 722, thereby driving the pressure plate 720 to move downward to filter the waste residue. When the push rod 722 is out of contact with the protrusion 721, the pressure plate 720 will automatically reset under the action of the second spring. The filtering effect of the pressure plate 720 can prevent the waste residue from accumulating too high in the collection tank 717 and flowing back into the fuel, thereby ensuring the purity and quality of the fuel and avoiding problems such as reduced purification effect and equipment corrosion caused by the backflow of waste residue.

The rotation of the disc 716 generates centrifugal force, which throws the waste residue in the grease to the outer edge of the disc 716 and finally deposits it in the collection tank 717. The rotation of the disc 716 not only realizes the centrifugal separation of the waste residue, but also provides power for the upward flow of the fuel. The fuel flows upward under the guidance of the disc 716, and finally flows into the interior of the square frame 617 through the action of the suction pump 5, ensuring the smooth flow of the fuel and avoiding poor fuel flow caused by waste residue blockage. When the disc 716 rotates, it will drive the push rod 722 to rotate. When the push rod 722 rotates, it will contact the protrusion 721. The protrusion 721 moves downward under the action of the push rod 722, thereby driving the pressure plate 720 to move downward to perform filter pressure treatment on the waste residue. When the push rod 722 is out of contact with the protrusion 721, the pressure plate 720 will automatically reset under the action of the second spring. The filter pressure effect of the pressure plate 720 can prevent the waste residue from accumulating too high in the collection tank 717 and flowing back into the fuel, ensuring the purity and quality of the fuel and avoiding problems such as reduced purification effect and equipment corrosion caused by the backflow of waste residue.

[0025] Working principle: When the square frame 617 moves forward and backward, it drives the second resistance rod 816 to move. Under the dual action of the resistance of the second resistance rod 816 and the torsion spring 815, the swing plate 814 rotates.
