Description

Technical Field

[0001] This invention relates to the field of blended oil production technology, specifically to a high-efficiency separation device and method for blended oil production. Background Technology

[0002] In the field of industrial blended oil production and processing, blended oil raw materials contain solid residues, gums, fibers and viscous impurities, which require specialized separation equipment to achieve rapid solid-liquid separation in order to improve the purity of the blended oil and ensure the stable operation of subsequent purification and refining processes. Existing screw presses, as the core equipment for solid-liquid separation of blended oil raw materials, are widely used in production processes such as waste oil recycling and industrial blended oil pretreatment.

[0003] Existing screw press separation equipment generally adopts a pressing separation structure, mainly composed of a screw press shaft, a screen cylinder, a feed inlet, a slag outlet, and an oil collection chamber. During operation, the mixed oil raw material is first fed into the screen cylinder through the feed inlet. Under the pushing and squeezing action of the screw press shaft, the oil seeps out through the screen cylinder pores and is collected in the oil collection chamber. The solid residue is transported by the screw press shaft to the slag outlet for discharge, realizing continuous solid-liquid separation. This equipment has a simple structure, large processing capacity, and low manufacturing cost. It can complete basic mixed oil solid-liquid separation operations and is widely used in the industry.

[0004] However, since the screen cylinder is directly fitted onto the outside of the screw press shaft, fine solid particles, gums, and sticky impurities in the mixed oil feedstock will directly accumulate, compact, and embed themselves into the screen cylinder pores during the extrusion process. Long-term use can easily cause the screen cylinder to become clogged. After clogging, the oil cannot seep out normally, the solid-liquid separation efficiency drops significantly, and frequent shutdowns and disassembly of the screen cylinder may be required. This not only affects production efficiency but also reduces the service life of the equipment, making it difficult to meet the continuous and stable mixed oil production separation requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency separation device and method for mixed oil production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency separation device for mixed oil production, comprising a main body, a frame, and a screen cylinder.

The bevel gear set is slidably connected to the first reciprocating screw. The outer wall of the active rotating plate is provided with a rack that meshes with the half-bevel gear.

[0010] Preferably, the filtering mechanism includes a second reciprocating screw mounted on the outer wall of the frame via bearings, and two sets of the second reciprocating screws are symmetrically arranged. A filter frame is slidably mounted on the top of the guide hopper, and the filter frame is threadedly connected to the second reciprocating screw. The length of the filter frame is less than the length of the second reciprocating screw. A pulley set is provided between the second reciprocating screw and the first reciprocating screw. The filter frame is provided with a uniform component to prevent material accumulation.

[0011] Preferably, the uniform assembly includes a movable frame slidably mounted on the inner wall of the filter frame, and the bottom of the movable frame is provided with levers distributed at equal intervals. The top of the filter frame is mounted with a third reciprocating screw via a bearing, and the third reciprocating screw is threadedly connected to the movable frame. The length of the movable frame is adapted to the length of the filter frame, and the movable frame is arranged parallel to the second reciprocating screw, while the third reciprocating screw is arranged perpendicular to the movable frame. A helical gear set is provided between the third reciprocating screw and the second reciprocating screw, and the helical gear set is slidably connected to the second reciprocating screw.

[0012] Preferably, the adjusting mechanism includes an adjusting plate slidably installed at the discharge end of the screen cylinder, and a pressure plate is fixedly installed on the outer wall of the adjusting plate. An electric push rod is fixedly installed on the outer wall of the frame, and the output end of the electric push rod is fixedly connected to the side of the adjusting plate away from the pressure plate. The top of the adjusting plate is provided with a speed regulating component for synchronously adjusting the cleaning speed of the anti-clogging mechanism according to the pressure.

[0013] Preferably, the speed regulating component is slidably mounted on the regulating seat on the top of the regulating plate, and a transmission wheel is mounted on the top of the regulating seat via a bearing. An active friction wheel is fixedly mounted on the output end of the drive motor, and a driven friction wheel is fixedly mounted on the end of the first reciprocating screw. Both the active and driven friction wheels have a frustum-shaped cross section, and the transmission wheel is located between the active and driven friction wheels.

[0014] Preferably, the method includes the following steps:

[0015] S1: The mixed oil raw material is fed into the screen cylinder. The drive motor and external water pump are started. The drive motor drives the first reciprocating screw to rotate, so that the moving frame moves back and forth along the length of the screen cylinder. The half bevel gear drives the active rotating plate and the driven rotating plate to rotate in opposite directions. The cleaning brush and the cleaning nozzle brush and spray the outer wall of the screen cylinder to prevent the screen from clogging.

[0016] S2: The first reciprocating screw drives the second reciprocating screw to rotate through the pulley set, causing the filter frame to sway back and forth along the top of the guide hopper, performing secondary filtration on the initially separated mixed oil. At the same time, the second reciprocating screw drives the third reciprocating screw to rotate through the helical gear set, causing the moving frame and the lever to move back and forth, preventing material accumulation in the filter frame.

[0017] S3: Based on the characteristics of the raw materials and the separation requirements, the position of the adjusting plate and the pressure plate is adjusted by the electric actuator to change the gap at the discharge port of the screen cylinder, thereby realizing the adjustment of the pressing pressure. The pressure change synchronously drives the displacement of the speed regulating component, automatically adjusting the speed of the first reciprocating screw to achieve the matching adjustment of cleaning force and pressing pressure.

[0018] S4: After the mixed oil is screw-pressed and double-filtered, the oil is collected by the feed hopper and the solid residue is discharged from the discharge end, completing a continuous and efficient solid-liquid separation operation.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, through the linkage cleaning design of the anti-clogging mechanism and the screen cylinder, adopts a reciprocating cleaning frame with forward and reverse rotating cleaning brushes, combined with a spray rinsing structure, to continuously clean the outer wall of the screen cylinder throughout the separation process. This effectively removes solid particles, colloids and sticky impurities accumulated in the pores, preventing screen clogging at the source, greatly improving solid-liquid separation efficiency and equipment continuous operation time, eliminating the need for frequent shutdowns and disassembly for cleaning, and significantly extending the service life of the equipment.

[0021] 2. This invention uses a filtration mechanism and an anti-clogging mechanism to work in sync. After the initial pressing and separation is completed, the mixed oil is subjected to secondary fine filtration by a reciprocating swaying filter frame. At the same time, a uniform component is used to dynamically move the material in the filter frame to prevent impurities from accumulating and clogging the filter screen. This allows solid-liquid separation and secondary purification to be completed simultaneously, effectively improving the purity of the mixed oil, ensuring the stable operation of subsequent purification processes, and making the separation quality more reliable.

[0022] 3. This invention, through the adaptive matching design of the adjustment mechanism and speed control component, can automatically adjust the speed of the first reciprocating screw according to the pressing pressure, so as to achieve synchronous adaptation between cleaning force and separation pressure. When the pressure is high, the cleaning effect on the filter cylinder is enhanced, and when the pressure is low, energy consumption is reduced. The entire process is automated and requires no manual intervention, which greatly improves the equipment's adaptability to different raw materials and different working conditions, making operation simpler, operation more stable, and energy saving more prominent.

The cleaning nozzles 26 are designed to be inclined and set towards the cleaning brush 24, and are used to cooperate with the cleaning brush 24 to rinse and clean the screen cylinder 12.

[0040] In one embodiment of the present invention, the filtration mechanism includes a second reciprocating screw 6 mounted on the outer wall of the frame 11 via bearings. Two sets of the second reciprocating screw 6 are symmetrically arranged. A filter frame 61 is slidably mounted on the top of the guide hopper 13. The filter frame 61 is threadedly connected to the second reciprocating screw 6, and the length of the filter frame 61 is less than the length of the second reciprocating screw 6. A pulley set is provided between the second reciprocating screw 6 and the first reciprocating screw 2 to realize synchronous power transmission.

[0041] The filter frame 61 is equipped with a uniform component to prevent material accumulation. The uniform component includes a movable frame 62 that is slidably installed on the inner wall of the filter frame 61. The bottom of the movable frame 62 is provided with levers 63 that are evenly distributed. The top of the filter frame 61 is equipped with a third reciprocating screw 7 through a bearing.

[0042] As one embodiment of the present invention, the adjustment mechanism includes an adjustment plate 8 slidably installed at the discharge end of the screen cylinder 12, a pressure plate 81 fixedly installed on the outer wall of the adjustment plate 8, an electric push rod 82 fixedly installed on the outer wall of the frame 11, and the output end of the electric push rod 82 is fixedly connected to the side of the adjustment plate 8 away from the pressure plate 81, for adjusting the discharge gap to change the pressing pressure.

A driven friction wheel 93 is fixedly mounted on the end of the first reciprocating screw 2. Both the active friction wheel 92 and the driven friction wheel 93 have a frustum-shaped cross section. The transmission wheel 91 is located between the active friction wheel 92 and the driven friction wheel 93. The speed is adjusted by changing the meshing position of the transmission wheel 91, thereby synchronously adjusting the cleaning force.

[0044] Based on the above embodiments, please refer to Figures 1-12 The method includes the following steps:

[0045] S1: The mixed oil raw material is fed into the screen cylinder 12. The drive motor 3 and the external water pump are started. The drive motor 3 drives the first reciprocating screw 2 to rotate, so that the moving frame 21 moves back and forth along the length of the screen cylinder 12. The half bevel gear 5 drives the active rotating plate 22 and the driven rotating plate 23 to rotate in opposite directions. The cleaning brush 24, together with the cleaning nozzle 26, brushes and sprays the outer wall of the screen cylinder 12 to prevent the screen from clogging.

[0046] S2: The first reciprocating screw 2 drives the second reciprocating screw 6 to rotate through the pulley set, causing the filter frame 61 to sway back and forth along the top of the guide hopper 13, performing secondary filtration on the initially separated mixed oil. At the same time, the second reciprocating screw 6 drives the third reciprocating screw 7 to rotate through the helical gear set, causing the moving frame 62 and the lever 63 to move back and forth, preventing material accumulation in the filter frame 61.

[0047] S3: Based on the characteristics of the raw materials and the separation requirements, the positions of the adjusting plate 8 and the pressure plate 81 are adjusted by the electric push rod 82 to change the gap at the discharge port of the screen cylinder 12, thereby realizing the adjustment of the pressing pressure. The pressure change synchronously drives the displacement of the speed regulating component, automatically adjusting the speed of the first reciprocating screw 2 to achieve the matching adjustment of cleaning force and pressing pressure.

[0048] S4: After the mixed oil is screw-pressed and double-filtered, the oil is collected by the feed hopper 13, and the solid residue is discharged from the discharge end, completing a continuous and efficient solid-liquid separation operation.

[0049] Working principle: When the high-efficiency separation device for mixed oil production is in standby mode, the frame 11, screen cylinder 12, and guide hopper 13 form a stable separation operation body. The moving frame 21 of the anti-clogging mechanism is stationary at the initial position at the end of the screen cylinder 12. The active rotating plate 22, the driven rotating plate 23, and the cleaning brush 24 are in contact with the outer wall of the screen cylinder 12. The cleaning spray pipe 25 and the external water pump are in standby mode. The filter frame 61 of the filtration mechanism is stationary at the top of the guide hopper 13. The moving frame 62 and the lever 63 of the uniform component are in the initial position. The adjusting plate 8 and the pressure plate 81 of the adjusting mechanism are in the normal position at the discharge end of the screen cylinder 12. The transmission wheel 91 of the speed regulating component is in the normal meshing position between the active friction wheel 92 and the driven friction wheel 93. The entire device is in the state of waiting to separate.

[0050] During the solid-liquid separation of mixed oil, the drive motor 3 starts, driving the two sets of first reciprocating screws 2 to rotate synchronously. The first reciprocating screws 2 drive the moving frame 21 to move back and forth along the length of the screen cylinder 12. The semi-bevel gear 5 inside the moving frame 21 rotates synchronously with the first reciprocating screws 2 through the bevel gear set. The semi-bevel gear 5 meshes with the rack 51 on the outer wall of the active rotating plate 22, driving the active rotating plate 22 to reciprocate along the outer periphery of the screen cylinder 12 within the moving frame 21. The active rotating plate 22... The side wall teeth 41 mesh with the transmission gear 4, driving the driven rotating plate 23 to rotate synchronously in the opposite direction. The cleaning brush 24 on the outer wall of the driving rotating plate 22 and the driven rotating plate 23 simultaneously brush the outer wall of the screen cylinder 12 in all directions. At the same time, the cleaning spray pipe 25 supplies water through an external water pump, and the cleaning nozzle 26 sprays water at an angle towards the screen cylinder 12 and the cleaning brush 24, realizing the simultaneous operation of brushing and spraying, effectively removing solid particles, colloids and sticky impurities accumulated in the pores of the screen cylinder 12, and avoiding clogging.

[0051] When the first reciprocating screw 2 rotates, it synchronously drives the second reciprocating screw 6 to rotate via the pulley set. The second reciprocating screw 6 drives the filter frame 61 to oscillate back and forth along the top of the guide hopper 13. The mixed oil after preliminary solid-liquid separation seeps out through the screen cylinder 12 and falls into the filter frame 61. The reciprocating oscillation of the filter frame 61 achieves secondary fine filtration of the oil, separating residual fine impurities. At the same time, the second reciprocating screw 6 drives the third reciprocating screw 7 to rotate via the helical gear set. The third reciprocating screw 7 drives the moving frame 62 to move back and forth along the inner wall of the filter frame 61. The lever 63 at the bottom of the moving frame 62 synchronously moves the oil and impurities in the filter frame 61 to prevent local accumulation of materials and blockage of the filter screen, ensuring continuous and efficient secondary filtration.

[0052] During the separation process, the adjustment mechanism, based on the characteristics of the mixed oil raw materials and the separation requirements, drives the adjustment plate 8 and the pressure plate 81 to slide along the discharge end of the screen cylinder 12 via the electric push rod 82, adjusting the discharge port gap to change the pressing pressure of the screw press. When the pressing pressure increases, the adjustment plate 8 drives the top adjustment seat 9 to move synchronously, causing the transmission wheel 91 to shift between the frustum-shaped active friction wheel 92 and the driven friction wheel 93, increasing the transmission ratio and simultaneously increasing the speed of the first reciprocating screw 2, thereby accelerating the reciprocating movement speed of the moving frame 21 and the rotation frequency of the cleaning brush 24, enhancing the cleaning force of the anti-clogging mechanism, and adapting to the high-pressure, high-clogging-risk operation requirements. When the pressing pressure decreases, the electric push rod 82 drives the adjustment plate 8 to reset, and the transmission wheel 91 shifts in the opposite direction to reduce the transmission ratio, reducing the speed of the first reciprocating screw 2 and the cleaning force, achieving synchronous adaptive adjustment of pressing pressure and cleaning force, optimizing energy consumption and cleaning effect while ensuring separation efficiency.

[0053] The mixed oil feedstock is pushed and squeezed by the spiral press shaft inside the screen cylinder 12. The oil seeps out through the pores of the screen cylinder 12 and is collected by the guide hopper 13. The solid residue is discharged from the discharge end, completing continuous solid-liquid separation. The anti-clogging mechanism, filtration mechanism and adjustment mechanism work together in the whole process without manual intervention, effectively solving the problems of screen clogging, low separation efficiency and mismatch between pressure regulation and cleaning, and meeting the separation requirements of continuous, stable and efficient mixed oil production.
