Description

Technical Field

[0001] The invention relates to the technical field of edible oil filtering, in particular to an accelerated filtering system and a filtering method for edible oil. Background Art

[0002] Edible oil, also known as "cooking oil", refers to animal or plant oils used in the process of making food, which is liquid at room temperature. Due to the source of raw materials, processing technology and quality, most common edible oils are plant oils, such as rapeseed oil, peanut oil, corn oil, olive oil, etc. When the oil press squeezes the plant oil from the plant, some residues and impurities will remain in the edible oil, so it is necessary to filter the squeezed edible oil. Centrifugal oil filtration is a method of rapid filtration of edible oil. Centrifugal filtration equipment is usually powered by a motor to drive the centrifugal barrel to rotate at high speed. When the squeezed edible oil enters the centrifugal barrel, it rotates at high speed under the action of the motor. Due to the different qualities of impurities and edible oil, the centrifugal force on the impurities is also different. The larger impurities are thrown to the periphery of the centrifugal barrel, while the oil is squeezed to the center of the centrifugal barrel. The edible oil is discharged from the filter, thereby separating the impurity particles from the edible oil. However, as the equipment works for a long time, the impurities attached to the filter increase, and the impurities will block the filter holes of the filter, making it difficult for the edible oil to pass through the filter, and the edible oil filtration speed will be reduced.

[0003] In order to avoid excessive accumulation of impurities on the filter screen, the impurities block the filter holes of the filter screen, resulting in a decrease in the edible oil filtration speed, the invention patent with application number CN202321451056.X provides a scraper-feeding automatic slag discharge centrifuge. The invention sets a support frame in the slag discharge centrifuge, and installs a drum on the support frame. When the drum rotates at high speed, the suspension is separated into solid and liquid. At this time, the solid particles are in the drum. Under the action of centrifugation, the liquid moves upward along the water inlet and is discharged from the water outlet. When the solid inside the drum needs to be cleaned, the rotation of the drum is first stopped, and then the scraper is rotated so that the scraper is in the drum. At this time, the drum is started to rotate slowly. Under the action of the scraper, the solid particles in the drum are scraped off. However, using a scraper to scrape off impurities filtered out of the edible oil will cause relative friction between the filter screen and the scraper, thereby reducing the service life of the filter screen. The scraper can only clean the impurities after the drum stops rotating. The equipment cannot perform centrifugal filtration of the used oil during the impurity cleaning period, which will affect the filtration efficiency of the edible oil.

[0004] Therefore, in order to avoid excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, which may block the filter holes of the filter screen and reduce the edible oil filtration speed, an accelerated filtration system and filtration method for edible oil are proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an accelerated filtering system and filtering method for edible oil. In order to prevent the centrifugal filtering equipment from working for a long time and the increase of impurities attached to the filter screen, the impurities will block the filter holes of the filter screen, making it difficult for the edible oil to pass through the filter screen, resulting in a slower edible oil filtering speed. By setting the centrifugal barrel as a rotatable swing plate and changing the inclination angle of the swing plate, the impurities accumulated on the filter screen are discharged from the slag discharge groove under the action of centrifugal force, reducing the influence of impurity accumulation on edible oil filtering, avoiding excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, and the impurities blocking the filter holes of the filter screen, resulting in a lower edible oil filtering speed, thereby improving the edible oil filtering speed and ensuring the edible oil filtering efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An accelerated filtering system and filtering method for edible oil, comprising a shell, a driving motor, an oil spray rod, a filter screen, a rotating assembly, and a swinging plate, wherein the driving motor is fixedly mounted on the shell, a slag discharge groove is provided on the top of the shell, an oil discharge port is provided on the bottom of the shell, the oil spray rod is vertically mounted inside the shell, an oil filling port is provided on the top of the oil spray rod, and oil spray ports are evenly provided on the oil spray rod, the rotating assembly is rotatably connected to the end of the oil spray rod, the rotating assembly is fixedly connected to the driving motor shaft, the driving motor drives the rotating assembly to perform forward and reverse rotation, the swinging plate is arranged in an arc trapezoid, four identical swinging plates are rotatably mounted on the rotating assembly, and the four swinging plates are arranged to form a circle when the tops of the four swinging plates are adjacent, the filter screen is arranged on the swinging plate and fits with the side wall of the swinging plate, the swinging plate is surrounded into a cylindrical shape when the rotating assembly rotates forward, and the swinging plate is tilted and swung in the vertical direction when the rotating assembly rotates reversely.

[0008] The oil spray rod is vertically installed inside the shell, and the tops of the four swing plates are surrounded by a circle to form a centrifugal barrel. The initially squeezed edible oil is pressurized and injected into the oil spray rod from the oil filling port. The edible oil is sprayed out from the oil spray port inside the shell and sprayed onto the filter screen covering the surface of the swing plate. The driving motor drives the rotating component to rotate, which drives the swing plate to rotate. Due to the different masses of impurities and edible oil, the centrifugal force they are subjected to is also different. The larger impurities are thrown onto the filter screen, and the edible oil is filtered into the shell through the filter screen. The filtered edible oil is discharged from the oil discharge port. When there are too many impurities attached to the filter screen and affect the edible oil filtering speed, the driving motor drives the rotating component to reverse and cause the swing plate to tilt. The top position of the swing plate remains unchanged, and the bottom position of the swing plate remains unchanged. Move closer to the oil spray rod. When the swing plate reverses, due to the different horizontal positions of all impurities on the same swing plate, the impurities at the bottom will gradually be thrown to the upper end of the swing plate under the influence of the rotating centrifugal force, and finally discharged from the slag discharge groove, changing the inclination angle of the swing plate. Under the action of centrifugal force, the impurities accumulated on the filter screen will be discharged from the slag discharge groove, reducing the influence of impurity accumulation on edible oil filtration, avoiding excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, and the impurities blocking the filter holes of the filter screen, resulting in a decrease in the edible oil filtration speed. When the rotating component rotates forward, the swing plate is perpendicular to the rotating bottom plate, so that different positions on the swing plate can be subjected to uniform centrifugal force, thereby improving the filtration speed of the edible oil and ensuring the filtration efficiency of the edible oil.

[0009] Preferably, the rotating assembly includes a rotating base plate, a cross plate, and a T-shaped slide bar. The swing plate is divided into an upper arc plate and a lower arc plate. The upper arc plate is slidably connected to the lower arc plate. Four identical arc slide grooves are arranged in an array on the rotating base plate. The four arc slide grooves penetrate the rotating base plate. When the rotating base plate is reversed, the trajectory radius of the arc slide groove gradually decreases. When the rotating base plate rotates forward, the trajectory radius of the arc slide groove gradually increases. The rotating base plate is rotatably mounted on the end of the spray rod. The rotating base plate is fixedly connected to the rotating shaft of the driving motor. The cross plate is rotatably mounted on the end of the spray rod. The cross plate is connected to the rotating base plate. The surface of the plate is fitted together, and four identical sliding grooves are opened on the cross plate, and T-shaped sliding bars are correspondingly slidably arranged in the four arc-shaped sliding grooves, one end of the T-shaped sliding bar passes through the sliding groove and is located in the arc-shaped sliding groove, and the bottom of the T-shaped sliding bar is fitted with the side wall of the arc-shaped sliding groove, the lower arc plate is hinged to the T-shaped sliding bar, and the upper arc plate is rotatably connected to the inner wall of the shell, and when the rotating base plate rotates, the T-shaped sliding bar is driven to slide in the sliding groove within a limited position, and the cross plate is provided with a vibration assembly, and a collision occurs between the vibration assembly and the swing plate, and a locking assembly is provided on the rotating base plate, and the locking assembly limits the rotation freedom of the swing plate.

[0010] When the driving motor rotates forward, the T-shaped slide bar is in close contact with one end of the arc slide groove. At this time, the axis of the swing plate is perpendicular to the rotating base plate. When the driving motor rotates reversely, under the limiting action of the cross plate, the T-shaped slide bar will move from one end of the arc slide groove to the other end along the trajectory of the arc slide groove and be in close contact with the inner wall of the other end of the arc slide groove. When the T-shaped slide bar slides inside the arc slide groove, it will also move in the sliding groove, moving from the outside of the cross plate to the center of the cross plate. The T-shaped slide bar drives the lower arc plate to move towards the direction close to the oil injection rod, and the bottom of the lower arc plate rotates. The angle between the axis of the swing plate and the rotating base plate gradually decreases, and relative sliding occurs between the upper arc plate and the lower arc plate. The swing plate becomes longer as a whole, and the original The swing plate that is vertical to the rotating bottom plate becomes inclined and connected to the rotating bottom plate. The cylindrical centrifugal barrel is deformed into a conical centrifugal barrel due to the rotation of the swing plate, and the cone head faces downward to change the centrifugal force on impurities at different positions, so that the impurities at the bottom move to the top of the swing plate under the action of the rotating centrifugal force. The relative sliding between the upper arc plate and the lower arc plate pulls the filter screen attached to the swing plate to stretch, and the filter holes between the filter screens are enlarged to facilitate the discharge of impurities on the filter screen. The driving motor changes the inclination angle of the swing plate by rotating forward and reversely, and changes the centrifugal force on impurities at different positions, and discharges impurities attached to the filter screen without adding a power source. The centrifugal filtering equipment does not need to be shut down to clean the impurities, which avoids excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, affecting the filtration speed of edible oil, improving the filtration speed of edible oil and saving production costs.

[0011] Preferably, the locking assembly includes a locking plate, a locking groove, and a locking rubber. The locking plate is vertically mounted on the side wall of the rotating base plate. A locking groove is provided on the locking plate. The locking rubber is arranged in an L shape. The locking rubber is fixedly mounted on the lower arc plate. The width of the locking rubber is 1-2 mm greater than the width of the locking groove.

[0012] By installing an L-shaped locking rubber on the lower arc plate, the locking rubber extends from the end surface of the lower arc plate, and when the rotating base plate rotates forward, the locking rubber cooperates with the locking groove to be inserted into the locking groove, thereby limiting the rotational freedom of the swing plate in the vertical direction. The width of the locking rubber is 1-2mm greater than the width of the locking groove, and there is an interference fit between the locking rubber and the locking groove. When the locking rubber is inserted into the locking groove, the friction between the locking rubber and the inner wall of the locking groove is increased to improve the locking effect. When the rotating base plate is reversed, the T-shaped slide bar drives the swing plate to rotate, and after the locking rubber leaves the locking groove, the swing plate can be limitedly rotated in the vertical direction. The locking assembly limits the rotational freedom of the swing plate in the vertical direction when the rotating base plate rotates forward, thereby preventing the swing plate from shaking during centrifugal filtration, which affects the service life of the swing plate and improves the system operation stability.

[0013] Preferably, the vibration assembly includes a rectangular frame, a long plate, an impact ball, a deformation spring, and a telescopic belt. The rectangular frame is fixedly mounted on the end of the cross plate, the bottom of the long plate is rotatably connected to the rectangular frame, the impact ball is fixedly mounted on the top of the long plate, the impact ball is made of rubber material, the two ends of the deformation spring are respectively connected to the inner wall of the rectangular frame and the side wall of the long plate, one end of the telescopic belt is fixedly mounted on the long plate, and the other end is fixedly connected to the T-shaped sliding rod.

[0014] The long plate is installed by rotating in the rectangular frame, and the two sides of the long plate are fitted with the inner wall of the rectangular frame, so that the impact ball is prevented from shaking left and right when the rotating bottom plate rotates forward. When the rotating bottom plate is reversed, the T-shaped slide bar moves in the direction close to the oil injection rod, the T-shaped slide bar pulls the telescopic belt, the deformation spring stretches, the long plate tilts in the direction close to the lower arc plate, and the impact ball contacts the surface of the lower arc plate. When the rotating bottom plate continues to reverse, due to the elastic force of the deformation spring and the telescopic belt, the impact ball will continuously impact the surface of the lower arc plate. Since the impurities centrifuged from the edible oil have a certain viscosity, a vibration component is set at the end of the cross plate. When the system is reversed to discharge slag, the impact ball impacts and vibrates the swing plate, so that the sticky impurities are subjected to vibration force, thereby reducing the adhesion of the impurities to the filter screen, so that the impurities are discharged from the slag discharge trough faster, thereby improving the slag discharge efficiency of the system and accelerating the edible oil filtering speed.

[0015] Preferably, a beryllium copper belt is provided between the two adjacent lower arc plates, the beryllium copper belt is arranged in a bent shape, and the protruding portion faces the direction of the fuel injection rod, and the concave portion of the beryllium copper belt is fixedly connected to the filter screen.

[0016] By arranging beryllium copper strips between each two adjacent lower arc plates, there are a total of four beryllium copper strips fitted with the filter screen. Beryllium copper is an alloy material with high elastic limit and fatigue limit, and has the characteristics of wear resistance, low temperature resistance, non-magnetic and corrosion resistance. When the cylindrical centrifugal barrel is deformed into a conical centrifugal barrel due to the rotation of the swing plate, the bending angle of the originally slightly bent beryllium copper strip increases, and the beryllium copper strip is concave inward and the distance between the beryllium copper strip and the injection rod is reduced. When the beryllium copper strip is deformed, it drives the filter screen to fold in the direction close to the injection rod, so that the impurities on the filter screen are located inside the centrifugal barrel for easy discharge of impurities, avoiding the situation that the filter screen may fold outward when the swing plate rotates inward, preventing the impurities from being squeezed outside the centrifugal barrel when the filter screen is folded, making it difficult to remove the impurities, and improving the slag discharge efficiency of the system.

[0017] Preferably, a flushing groove is provided inside the rotating bottom plate, and the flushing groove is communicated with the arc-shaped slide groove; a flushing hole is provided on the locking plate, and the flushing hole is communicated with the flushing groove.

[0018] By opening a plurality of cross-shaped connected flushing grooves inside the rotating bottom plate, the flushing grooves are connected to the turning parts and circular arc depressions of the arc chute, and the flushing holes on the locking plate are connected to the flushing grooves. When liquid is injected into the flushing holes, the liquid can flow out of the arc chute through the flushing grooves. After the system has been running for a long time, some impurities will accumulate in the turning parts and circular arc depressions of the arc chute. The accumulation of impurities will affect the sliding effect of the T-shaped slide bar, thereby affecting the stable operation of the system. At this time, the rotating bottom plate needs to be cleaned of impurities. Only by injecting cleaning liquid into the flushing holes on the locking plate can the impurities in all the arc chute be flushed away, which is convenient for the staff to clean the system and improves the cleaning efficiency.

[0019] Preferably, the sliding groove is arranged in a cross shape, and a sliding block is arranged on the T-shaped sliding rod, and the sliding block is fitted with the inner wall of the sliding groove.

[0020] By arranging a sliding block in the middle of the T-shaped slide bar, when the rotating base plate drives the T-shaped slide bar to move, the sliding block slides inside the slide groove, and the sliding block fits against the inner wall of the slide groove. When the rotating base plate and the cross plate rotate relative to each other, the stress on the rod of the T-shaped slide bar is reduced, and at the same time, the stable sliding of the T-shaped slide bar is improved, thereby improving the stability of system operation.

[0021] An edible oil filtering method for the above-mentioned edible oil accelerated filtering system comprises the following steps:

[0022] S1, the edible oil squeezed out from the oil press flows into the oil spray rod, and the edible oil sprays out from the oil spray port;

[0023] S2, the driving motor rotates forward to drive the rotating bottom plate to rotate, and the rotating bottom plate causes the swing plate to rotate forward, and the edible oil is filtered from the filter screen by rotating centrifugation;

[0024] S3, when there are too many impurities on the filter screen, the edible oil filtering speed slows down, and the driving motor reverses to drive the rotating bottom plate to reverse;

[0025] S4, after the rotating bottom plate is reversed, the T-shaped slide bar moves within the arc-shaped slide groove, causing the swing plate to rotate in the vertical direction and the lower arc plate to move closer;

[0026] S5, at this time, the position between the swing plates changes, the driving motor continues to reverse, and the impurities are moved upward under the action of centrifugal force and finally discharged from the slag discharge trough;

[0027] S6. After the impurities are discharged, the driving motor rotates forward. At this time, the impurities on the filter have been removed, increasing the speed at which the edible oil passes through the filter, thereby completing the accelerated filtration of the edible oil.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. By changing the inclination angle of the swing plate, the impurities accumulated on the filter screen are discharged from the slag discharge groove under the action of centrifugal force, reducing the influence of impurity accumulation on edible oil filtration, avoiding excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, and blocking the filter holes of the filter screen by impurities, resulting in a decrease in the edible oil filtration speed. When the rotating assembly rotates forward, the swing plate is perpendicular to the rotating bottom plate, so that different positions on the swing plate can be subjected to uniform centrifugal force, thereby improving the filtration speed of edible oil and ensuring the filtration efficiency of edible oil.

[0030] 2. By driving the motor to rotate forward and reverse to change the inclination angle of the swing plate, the centrifugal force exerted on impurities at different positions is changed, and the impurities attached to the filter screen can be discharged without adding a power source. The centrifugal filtering equipment does not need to be shut down to clean the impurities, thus avoiding excessive accumulation of impurities on the filter screen during centrifugal filtration of edible oil, affecting the filtration speed of edible oil, improving the filtration speed of edible oil and saving production costs.

[0031] 3. By setting a vibration component at the end of the cross plate, the impact ball will impact and vibrate the swing plate when the system is reversed to discharge slag, so that the sticky impurities are subjected to the vibration force, thereby reducing the adhesion of the impurities to the filter screen, allowing the impurities to be discharged from the slag discharge trough faster, thereby improving the system slag discharge efficiency and accelerating the edible oil filtration speed.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 8 The present invention provides an accelerated filtration system for edible oil, and the technical solution is as follows:

[0045] The driving motor 2 is fixedly mounted at the bottom of the housing 1. Two slag discharge grooves 101 are symmetrically arranged above the housing 1. The slag discharge grooves 101 are connected to the inside of the housing 1. Impurities centrifugally filtered from the filtering system are discharged from the slag discharge grooves 101. An oil discharge port 102 is arranged at the bottom of the housing 1. The edible oil that has been centrifugally filtered is discharged from the oil discharge port 102. The oil spray rod 3 penetrates the housing 1 from the top of the housing 1 and is vertically mounted inside the housing 1. An oil injection port 31 is arranged at the top of the oil spray rod 3. The portion of the oil spray rod 3 extending into the inside of the housing 1 is evenly provided with oil injection ports 32. The edible oil that has been initially squeezed is injected into the oil injection port 31. The edible oil is injected into the oil spray rod 3 under pressure, and the edible oil is sprayed out from the oil spray port 32. A rotating assembly 5 is arranged inside the housing 1. One end of the rotating assembly 5 is rotatably connected to the lower end of the oil spray rod 3, and the other end is fixedly connected to the rotating shaft of the driving motor 2. The driving motor 2 can drive the rotating assembly 5 to rotate forward and reverse. Four identical swing plates 6 are rotatably installed on the rotating assembly 5. The swing plates 6 are arranged in an arc trapezoidal shape. When the four swing plates 6 are close together, the tops of the swing plates 6 form a circle to form a centrifugal barrel. The surface of the swing plates 6 is provided with a filter screen 4 that fits the swing plates 6. The edible oil sprayed from the oil spray port 32 is sprayed to the covering On the filter screen 4 on the surface of the swing plate 6, the driving motor 2 drives the rotating assembly 5 to rotate, which drives the swing plate 6 to rotate. Due to the different masses of impurities and edible oil, the centrifugal force they are subjected to is also different. The impurities with larger masses are thrown onto the filter screen 4, and the edible oil is filtered into the housing 1 through the filter screen 4. The filtered edible oil is discharged from the oil discharge port 102. When too many impurities attached to the filter screen 4 affect the edible oil filtering speed, the driving motor 2 drives the rotating assembly 5 to reverse and tilt the swing plate 6. The top position of the swing plate 6 remains unchanged, and the bottom of the swing plate 6 moves closer to the spray rod 3. When the swing plate 6 is reversed, since all impurities on the same swing plate 6 are located at different horizontal positions, the impurities at the bottom will be gradually thrown to the upper end of the swing plate 6 under the influence of the rotating centrifugal force, and finally discharged from the slag discharge groove 101, the inclination angle of the swing plate 6 is changed, and the impurities accumulated on the filter screen 4 are discharged from the slag discharge groove 101 under the action of the centrifugal force, thereby reducing the influence of the impurity accumulation on the edible oil filtration, avoiding excessive accumulation of impurities on the filter screen 4 during the centrifugal filtration of the edible oil, and the impurities blocking the filter holes of the filter screen 4, resulting in a decrease in the edible oil filtration speed, thereby improving the edible oil filtration speed and ensuring the edible oil filtration efficiency.

[0046] As an embodiment of the present invention, refer to Figures 2 to 8The rotating assembly 5 includes a rotating base plate 51, a cross plate 52, and a T-shaped slide bar 53. The swing plate 6 is divided into an upper arc plate 61 and a lower arc plate 62. The upper arc plate 61 and the lower arc plate 62 are slidably connected. One end of the arc base plate is rotatably connected to the lower end of the spray rod 3, and the other end is fixedly connected to the rotating shaft of the driving motor 2. Four identical arc slide grooves 511 are arranged in an array on the arc base plate. The four arc slide grooves 511 penetrate the rotating base plate 51. The cross plate 52 fits the surface of the rotating base plate 51. The cross plate 52 is rotatably installed at the end of the spray rod 3. The rotating base plate 51 and the cross plate 52 can rotate around the axis of the spray rod 3. Four identical slide grooves 521 are arranged on the cross plate 52. Each slide groove 521 has a A T-shaped slide bar 53 is provided corresponding to the sliding. One end of the T-shaped slide bar 53 passes through the slide groove 521 and is located in the arc slide groove 511. The bottom of the T-shaped slide bar 53 fits the side wall of the arc slide groove 511. The lower arc plate 62 is hinged to the top of the T-shaped slide bar 53. The upper arc plate 61 is rotatably connected to the inner wall of the shell 1. When the rotating base plate 51 rotates, the T-shaped slide bar 53 is driven to slide in the slide groove 521. The four ends of the cross plate 52 are respectively provided with vibration components 7. The vibration component 7 can collide with the swing plate 6. The rotating base plate 51 is provided with a locking component 8. The locking component 8 limits the rotational freedom of the swing plate 6 to prevent the swing plate 6 from shaking when the rotating base plate 51 rotates forward. When the driving motor 2 rotates forward,The T-shaped slide bar 53 is in close contact with one end of the arc-shaped slide groove 511. At this time, the axis of the swing plate 6 is perpendicular to the rotating base plate 51. When the driving motor 2 is reversed, under the limiting action of the cross plate 52, the T-shaped slide bar 53 will move from one end of the arc-shaped slide groove 511 to the other end along the trajectory of the arc-shaped slide groove 511, and will be in close contact with the inner wall of the other end of the arc-shaped slide groove 511. While sliding inside the arc-shaped slide groove 511, the T-shaped slide bar 53 will also move in the slide groove 521, moving from the outside of the cross plate 52 to the center of the cross plate 52, and the T-shaped slide bar 53 will drive The lower arc plate 62 moves toward the direction of the oil spray rod 3, and the bottom of the lower arc plate 62 rotates. The angle between the axis of the swing plate 6 and the rotating bottom plate 51 gradually decreases, and relative sliding occurs between the upper arc plate 61 and the lower arc plate 62. The swing plate 6 becomes longer as a whole. The swing plate 6, which was originally perpendicular to the rotating bottom plate 51, becomes inclined and connected to the rotating bottom plate 51. The cylindrical centrifugal barrel is deformed into a conical centrifugal barrel due to the rotation of the swing plate 6, and the cone head faces downward. Therefore, when the rotating bottom plate 51 is reversed, the centrifugal force on impurities at different positions is changed, so that the impurities at the bottom are The impurities on the filter screen 4 are discharged by the driving motor 2. The inclination angle of the swing plate 6 is changed by the positive and negative rotation of the driving motor 2, and the centrifugal force on the impurities at different positions is changed. The impurities attached to the filter screen 4 are discharged without adding a power source. The centrifugal filtering equipment does not need to be shut down to clean the impurities, which avoids the impurities on the filter screen 4 during the centrifugal filtration of edible oil. Excessive accumulation of particles affects the filtration speed of edible oil, which improves the filtration speed of edible oil and saves production costs; the sliding groove 521 is set in a cross shape, and a sliding block 10 is set on the T-shaped slide bar 53. The sliding block 10 fits with the inner wall of the sliding groove 521. When the rotating bottom plate 51 drives the T-shaped slide bar 53 to move, the sliding block 10 fits with the inner wall of the sliding groove 521 and slides. When the rotating bottom plate 51 and the cross plate 52 rotate relative to each other, the stress on the rod of the T-shaped slide bar 53 is reduced, and the stable sliding of the T-shaped slide bar 53 is improved, thereby improving the stability of the system operation.

[0047] As an embodiment of the present invention, refer to Figures 2 to 8The locking assembly 8 includes a locking plate 81, a locking groove 82, and a locking rubber 83. The locking plate 81 is vertically mounted on the side wall of the rotating base plate 51. The locking plate 81 is provided with a locking groove 82. The locking rubber 83 is arranged in an L-shape and fixedly mounted on the lower arc plate 62. The locking rubber 83 extends from the end surface of the lower arc plate 62. When the rotating base plate 51 rotates forward, the locking rubber 83 cooperates with the locking groove 82 and is inserted into the locking groove 82 to limit the rotational freedom of the swing plate 6 in the vertical direction. The width of the locking rubber 83 is greater than the width of the locking groove 82 by 2 mm. The locking rubber 83 and the locking groove 82 are interference-fitted. When the locking rubber 83 is inserted into the locking groove 82, the locking rubber 83 is enlarged. The friction between the rubber 83 and the inner wall of the locking groove 82 improves the locking effect. When the rotating base plate 51 is reversed, the T-shaped slide bar 53 drives the swing plate 6 to rotate. After the locking rubber 83 leaves the locking groove 82, the swing plate 6 can be limited in rotation in the vertical direction. When the rotating base plate 51 rotates forward, the locking component 8 limits the rotational freedom of the swing plate 6 in the vertical direction, thereby preventing the swing plate 6 from shaking during centrifugal filtration and affecting the service life of the swing plate 6, thereby improving the operating stability of the system; the vibration component 7 includes a rectangular frame 71, a long plate 72, an impact ball 73, a deformation spring 74, and a telescopic belt 75. The rectangular frame 71 is fixedly installed at the end of the cross plate 52, and the impact ball 73 is The cam 73 is made of rubber material and is fixedly mounted on the top of the long plate 72. The long plate 72 is arranged in the rectangular frame 71. The bottom of the long plate 72 is rotatably connected to the rectangular frame 71. The two sides of the long plate 72 are in contact with the inner wall of the rectangular frame 71 to prevent the impact ball 73 from shaking left and right when the rotating base plate 51 rotates forward. One end of the deformation spring 74 is connected to the inner wall of the rectangular frame 71, and the other end is connected to the side wall of the long plate 72. A telescopic belt 75 is fixedly installed on the other side of the long plate 72. The other end of the telescopic belt 75 is fixedly connected to the T-shaped slide bar 53. When the rotating base plate 51 is reversed, the T-shaped slide bar 53 moves toward the direction close to the injection rod 3. The T-shaped slide bar 53 pulls the telescopic belt 75, and the deformation spring 74 stretches The long plate 72 is inclined toward the direction close to the lower arc plate 62, and the impact ball 73 contacts the surface of the lower arc plate 62. When the rotating bottom plate 51 continues to reverse, due to the elastic force of the deformation spring 74 and the telescopic belt 75, the impact ball 73 will continuously impact the surface of the lower arc plate 62. Since the impurities centrifuged from the edible oil have a certain viscosity, a vibration component 7 is arranged at the end of the cross plate 52. When the system is reversed to discharge slag, the impact ball 73 impacts and vibrates the swing plate 6, so that the viscous impurities are subjected to the vibration force, thereby reducing the adhesion of the impurities to the filter screen 4, so that the impurities are discharged from the slag discharge groove 101 faster, thereby improving the slag discharge efficiency of the system and accelerating the filtering speed of the edible oil.The interior of the rotating bottom plate 51 is provided with a plurality of cross-shaped connected flushing grooves 512, and the flushing grooves 512 are connected to the shape turning parts and the arc depressions of the arc chute 511, and the flushing holes 811 on the locking plate 81 are connected to the flushing grooves 512. When liquid is injected into the flushing holes 811, the liquid can flow out of the arc chute 511 through the flushing grooves 512. After the system has been running for a long time, some impurities will accumulate at the shape turning parts and the arc depressions of the arc chute 511. The accumulation of impurities will affect the sliding effect of the T-shaped slide bar 53, thereby affecting the stable operation of the system. At this time, it is necessary to clean the impurities from the rotating bottom plate 51, and as long as the cleaning liquid is injected into the flushing holes 811 on the locking plate 81, all the impurities in the arc chute 511 can be flushed and cleaned, which is convenient for the staff to clean the system and improves the cleaning efficiency; a Beryllium copper belt 9, beryllium copper belt 9 is set to a bent shape, and the protruding part faces the direction of the injection rod 3, the concave part of beryllium copper belt 9 is fixedly connected to the filter 4, and there are four beryllium copper belts 9 in total that fit the filter 4. Beryllium copper is an alloy material with high elastic limit and fatigue limit, and has the characteristics of wear resistance, low temperature resistance, non-magnetic and corrosion resistance. When the cylindrical centrifugal barrel is deformed into a conical centrifugal barrel due to the rotation of the swing plate 6, the bending angle of the originally slightly bent beryllium copper belt 9 increases, and the distance between the beryllium copper belt 9 and the injection rod 3 decreases. When the beryllium copper belt 9 is deformed, it drives the filter 4 to fold in the direction close to the injection rod 3, so that the impurities on the filter 4 are in the inside of the centrifugal barrel for easy discharge of impurities, avoiding the situation that the filter 4 may fold outward when the swing plate 6 rotates inward, and preventing the filter 4 from squeezing the impurities outside the centrifugal barrel when folding, making it difficult to remove the impurities, and improving the slag discharge efficiency of the system. ;

[0048] Edible oil filtration method and working principle using the above-mentioned edible oil accelerated filtration system:

[0049] refer to Figures 1 to 9: The edible oil that is initially squeezed is pressurized and injected into the oil injection rod 3 from the oil injection port 31, and the edible oil is sprayed out from the oil injection port 32 inside the housing 1. The driving motor 2 drives the rotating bottom plate 51 to rotate forward, driving the swing plate 6 to rotate. At this time, the locking rubber 83 is located in the locking groove 82, and the locking rubber 83 limits the rotational freedom of the swing plate 6 in the vertical direction. During the continuous rotation of the swing plate 6, due to the different masses of impurities and edible oil, the centrifugal force they are subjected to is also different. The impurities with larger mass are thrown onto the filter screen 4, and the edible oil is filtered into the housing 1 through the filter screen 4. The filtered edible oil is discharged from the oil discharge port 102. When there are too many impurities attached to the filter screen 4, which affects the filtering speed of the edible oil, the rotating bottom plate 51 is reversed when the motor 2 is driven. Under the limiting effect of the cross plate 52, the T-shaped slide bar 53 moves from one end of the arc-shaped slide groove 511 to the other end along the trajectory of the arc-shaped slide groove 511, and is tightly attached to the inner wall of the other end of the arc-shaped slide groove 511. While sliding inside the arc-shaped slide groove 511, the T-shaped slide bar 53 also moves in the slide groove 521, and moves from the outside of the cross plate 52 to the center of the cross plate 52. The T-shaped slide bar 53 drives the lower arc plate 62 to move toward the direction of the injection rod 3, and the bottom of the lower arc plate 62 rotates. The angle between the axis of the swing plate 6 and the rotating bottom plate 51 gradually decreases, and relative sliding occurs between the upper arc plate 61 and the lower arc plate 62. The swing plate 6 becomes longer as a whole. The swing plate 6, which was originally perpendicular to the rotating bottom plate 51, becomes inclined and connected to the rotating bottom plate 51. The cylindrical centrifugal barrel is deformed into a conical centrifugal barrel due to the rotation of the swing plate 6, and the cone head faces downward. The beryllium copper belt 9, which was originally slightly bent, has an increased bending angle, and the beryllium copper belt 9 is bent to The distance between the inner depression and the oil spray rod 3 is reduced, and the beryllium copper belt 9 is deformed while driving the filter screen 4 to fold in the direction close to the oil spray rod 3. When the movement of the T-shaped slide bar 53 pulls the telescopic belt 75, the impact ball 73 contacts the surface of the lower arc plate 62. When the rotating bottom plate 51 continues to reverse, the impact ball 73 continuously impacts the surface of the lower arc plate 62. Since the swing plate 6 changes its inclination angle, impurities at different positions are subjected to different centrifugal forces. The impurities at the bottom will gradually move upward and be discharged from the slag discharge port. After the slag discharge work is completed, the drive motor 2 rotates forward to accelerate the filtration of the edible oil.
