Technical Field

[0001] This invention relates to the field of flatbed centrifuge technology, specifically to a flatbed centrifuge that is easy to clean. Background Technology

[0002] Centrifuges are a common laboratory device used to separate components in a mixture by means of rotational acceleration. A plate centrifuge is one type of centrifuge, which places centrifuge cups on a rotating platform and separates the mixture into different layers by centrifugal force.

[0003] Patent application number CN201921601182.2 relates to a plate centrifuge that is easy to clean. This centrifuge solves the problem of inconvenient cleaning and maintenance of existing plate centrifuges. It includes a chassis, a drum mounted on the chassis, and a shell covering the drum. The shell is composed of two opposing sleeves. Each sleeve includes a semi-circular arc plate slidably connected to the upper surface of the chassis and a cover plate fixedly connected to one end of the semi-circular arc plate away from the chassis. The chassis is equipped with a drive assembly for driving the sleeves to slide and having a limiting function. This patent facilitates the maintenance or cleaning of the interior of the plate centrifuge. However, this device involves disassembling the centrifuge body into two halves for cleaning. While this is convenient, repeated disassembly can weaken the seal at the centrifuge's joints, leading to leakage. Therefore, this patent proposes a plate centrifuge that is easy to clean to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flat plate centrifuge that is easy to clean, in order to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a flat plate centrifuge that is easy to clean, comprising a shell, and further comprising a cleaning device, a scraping device, an agitating device, and a unblocking device; a top cover is rotatably mounted on the top of the shell, a motor is fixedly connected to the bottom of the shell, an inner cylinder is installed at the output end of the motor, and a discharge pipe is fixedly connected to the bottom of the shell; the cleaning device comprises a rotating plate, rollers, a transmission rod, and a scraper, the rotating plate is mounted on the output end of the motor, the rollers are rotatably connected to the top of the rotating plate, the transmission rod is fixedly connected to the shaft at the top of the rollers, and the scraper is fixedly connected to the surface of the transmission rod; the scraping device is disposed on the top of the rotating plate, and the agitating device is disposed on the surface of the scraping device; the... The unblocking device is installed on the inner wall of the rotating plate; the surface of the roller is in contact with the inner wall of the housing, the side of the scraper away from the transmission rod is in contact with the inner wall of the housing, and the bottom of the rotating plate is in contact with the inner wall of the housing. After the centrifuge is used, the top cover is opened and the inner cylinder is taken out. Then, the rotating plate is installed on top of the motor and water is added for cleaning. At this time, the motor starts and drives the rotating plate to rotate clockwise. The rotating plate will drive the transmission rod on the roller to rotate. The transmission rod will drive the scraper to clean and remove impurities from the inner wall of the housing. At the same time, when the roller is driven, it will contact the inner wall of the housing and drive the roller itself to rotate. The roller will drive the scraper on the transmission rod to rotate, so that the scraper can further scrape and clean the inner wall of the housing, improving the cleaning effect.

[0006] Preferably, the scraping device includes a fixed disc, a pulley, and a cleaning roller. The fixed disc is fixedly connected to the top of the rotating plate, the pulley is rotatably connected to the inner wall of the fixed disc, and the cleaning roller is fixedly connected to the axis of the pulley. The scraping device also includes a reciprocating screw, a moving plate, a guide rod, and a protrusion. The reciprocating screw is movably connected to the inner wall of the cleaning roller, the moving plate is fixedly connected to the front end of the reciprocating screw, the guide rod is fixedly connected to both ends of the moving plate, and the protrusion is fixedly connected to the center of the moving plate. The surface of the protrusion after movement contacts the inner wall of the housing, and the surface of the cleaning roller rotates with respect to the inner wall of the fixed disc. The guide rod is slidably connected to the inner wall of the fixed plate, and the pulley is in contact with the inner wall of the housing. When the rotating plate rotates, it drives the fixed plate to rotate, which in turn drives the pulley to rotate. The pulley contacts the housing and is driven to rotate on its own. The pulley drives the cleaning roller to rotate, which further cleans the bottom wall inside the housing, improving the cleaning effect of the centrifuge. At the same time, the rotation of the cleaning roller drives the reciprocating screw guided by the guide rod to move back and forth. The reciprocating screw drives the protrusions on the moving plate to repeatedly strike the inner wall of the housing, thereby shaking off impurities on the inner wall of the housing and further improving the cleaning effect.

[0007] Preferably, the agitating device includes a transmission plate, a rotating ring, an elastic arc plate, a push rod, and an elastic plate. The transmission plate is fixedly connected to the top of the fixed disk, the rotating ring is movably connected to the inner wall of the transmission plate, both sides of the elastic arc plate are fixedly connected to the inner wall of the rotating ring, the elastic plate is fixedly connected to the surface of the transmission plate, and the push rod is fixedly connected to the bottom of the elastic plate. The agitating device also includes an arc-shaped rod and an elastic telescopic plate. The arc-shaped rod is rotatably connected to the inner wall of the rotating ring via a torsion spring, and the elastic telescopic plate is rotatably connected to the inner wall of the elastic plate via a torsion spring. The surface of the arc-shaped rod is in contact with the surface of the elastic telescopic plate. The bottom of the rotating ring is in contact with the surface of the pulley, the upper surface of the elastic arc plate is in contact with the end of the push rod away from the elastic plate, and the upper surface of the elastic arc plate after movement is in contact with the inner wall of the transmission plate. When the fixed disk rotates, it will drive the transmission plate to rotate. The transmission plate agitates the water flow within the housing, enhancing its cleaning effect. Simultaneously, the rotation of the pulley drives the rotating ring in contact with it to rotate. The rotating ring moves along the inner wall of the transmission plate. When the rotating ring moves the elastic arc plate to the transmission plate, the transmission plate limits the elastic arc plate, causing the arched elastic arc plate to press into the inner wall of the rotating ring. After the elastic arc plate passes the transmission plate, under the action of elasticity, the elastic arc plate arches again and pushes the top rod above it upward. The top rod pushes the elastic plate upward, causing the elastic plate to arch and further agitate the water flow. At the same time, when the rotating ring moves the arc rod to the transmission plate, the transmission plate pushes the arc rod to rotate into the rotating ring. When the arc rod passes the transmission plate, the torsion spring drives the arc rod to rotate out of the rotating ring and pushes the elastic telescopic plate to rotate. The elastic telescopic plate pushes the water flow towards the inner wall of the housing, causing the water flow to impact the inner wall of the housing and wash away impurities adhering to the surface.

[0008] Preferably, the unblocking device includes a turntable, a spiral sleeve, a pressure rod, and a limiting plate. The turntable is rotatably connected to the top of a rotating plate, the spiral sleeve is movably connected to the inner wall of the turntable, the pressure rod is movably connected to the inner wall of the spiral sleeve, and the limiting plate is fixedly connected to the top of the pressure rod. A spring is provided between the limiting plate and the spiral sleeve. The surface of the spiral sleeve has cross-shaped spiral grooves. A locking block is provided on the inner wall of the turntable, and the locking block is located in the cross-shaped spiral grooves. The surface of the turntable is in contact with the surface of the roller, and the surface of the spiral sleeve is slidably connected to the inner wall of the rotating plate. When the roller rotates, it will... The rotating disc in contact with the rotating disc rotates, and the rotating disc drives the rotating disc to rotate through the intersecting spiral grooves on the spiral disc. However, the spiral disc is limited by the rotating plate and can only move. Therefore, the rotating disc drives the spiral disc to move up and down back and forth. When the spiral disc moves down, it drives the spring to pull the limiting plate down. The limiting plate drives the pressure rod down. When the pressure rod moves to the discharge pipe, it will extend into the discharge pipe and clear its interior to prevent impurities from clogging the discharge pipe. When the pressure rod continues to move, the spiral disc moves up and pushes the pressure rod up through the spring and the limiting plate, so that the pressure rod moves out of the discharge pipe for easy clearing next time.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This easy-to-clean flatbed centrifuge works by coordinating the shell, top cover, inner cylinder, discharge pipe, motor, rotating plate, rollers, transmission rod, and scraper. After use, the top cover is opened and the inner cylinder is removed. Then, the rotating plate is installed on top of the motor and water is added for cleaning. The motor starts and rotates the rotating plate clockwise. The rotating plate drives the transmission rod on the rollers to rotate, and the transmission rod drives the scraper to clean and remove impurities from the inner wall of the shell. The interior can be effectively cleaned without opening and disassembling the shell.

[0011] 2. This easy-to-clean flat plate centrifuge works by coordinating a fixed plate, pulleys, cleaning rollers, reciprocating screws, moving plate, guide rods, and protrusions. When the rotating plate rotates, it drives the fixed plate to rotate, which in turn drives the pulleys to rotate. The pulleys contact the housing and are driven to rotate on their own, which in turn drives the cleaning rollers to rotate. The cleaning rollers further clean the bottom wall inside the housing, improving the cleaning effect of the centrifuge.

[0012] 3. This easy-to-clean flat plate centrifuge works by coordinating the transmission plate, rotating ring, elastic arc plate, top rod, elastic plate, arc rod, and elastic telescopic plate. When the fixed plate rotates, it drives the transmission plate to rotate, which agitates the water flow in the shell, improving the cleaning effect of the water flow on the inside of the shell. The elastic plate and elastic telescopic plate also further promote the water flow.

[0013] 4. This easy-to-clean flat plate centrifuge operates through the coordinated operation of a turntable, a spiral sleeve, a pressure rod, and a limiting plate. When the rollers rotate, they drive the turntable in contact with them to rotate. The turntable drives the spiral sleeve to rotate through the locking blocks on the inner wall and the cross spiral grooves on the spiral sleeve. However, the spiral sleeve is limited by the rotating plate and can only move. Therefore, the turntable drives the spiral sleeve to move up and down reciprocally. When the spiral sleeve moves down, it drives the spring to pull the limiting plate down. The limiting plate drives the pressure rod down. When the pressure rod moves to the discharge pipe, it extends into the discharge pipe and clears its interior to prevent impurities from clogging the discharge pipe. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5One embodiment of the present invention is as follows: a flat plate centrifuge that is easy to clean, comprising a housing 1, and further comprising a cleaning device, a scraping device 6, an agitating device 7, and a unblocking device 8; a top cover 2 is rotatably mounted on the top of the housing 1, a motor 5 is fixedly connected to the bottom of the housing 1, an inner cylinder 3 is mounted on the output end of the motor 5, and a discharge pipe 4 is fixedly connected to the bottom of the housing 1; the cleaning device comprises a rotating plate 51, a roller 52, a transmission rod 53, and a scraper 54, the rotating plate 51 is mounted on the output end of the motor 5, the roller 52 is rotatably connected to the top of the rotating plate 51, the transmission rod 53 is fixedly connected to the shaft at the top of the roller 52, and the scraper 54 is fixedly connected to the surface of the transmission rod 53. After the centrifuge is used, the top cover 2 is opened and the inner cylinder 3 is removed, then the rotating plate 51 is mounted on the top of the motor 5 and water is added for cleaning. At this time, the motor 5 starts and drives the rotating plate 51 to rotate clockwise. The rotating plate 51 drives the transmission rod 53 on the roller 52 to rotate. The transmission rod 53 drives the scraper 54 to clean and remove impurities from the inner wall of the housing 1. The scraping device 6 is set on the top of the rotating plate 51, the stirring device 7 is set on the surface of the scraping device 6, and the unblocking device 8 is set on the inner wall of the rotating plate 51. The surface of the roller 52 is in contact with the inner wall of the housing 1, the side of the scraper 54 away from the transmission rod 53 is in contact with the inner wall of the housing 1, and the bottom of the rotating plate 51 is in contact with the inner wall of the housing 1. When the roller 52 is driven, it will contact the inner wall of the housing 1 and drive the roller 52 to rotate. The roller 52 will drive the scraper 54 on the transmission rod 53 to rotate, so that the scraper 54 will further scrape and clean the inner wall of the housing 1, improving the cleaning effect.

[0025] The scraping device 6 includes a fixed disk 61, a pulley 62, and a cleaning roller 63. The fixed disk 61 is fixedly connected to the top of the rotating plate 51, the pulley 62 is rotatably connected to the inner wall of the fixed disk 61, and the cleaning roller 63 is fixedly connected to the axis of the pulley 62. When the rotating plate 51 rotates, it drives the fixed disk 61 to rotate, which in turn drives the pulley 62 to rotate. The pulley 62 contacts the housing 1 and is driven to rotate itself, which in turn drives the cleaning roller 63 to rotate. The cleaning roller 63 further cleans the bottom wall inside the housing 1, improving the cleaning effect of the centrifuge. The scraping device 6 also includes a reciprocating screw 631, a moving plate 632, a guide rod 633, and a protrusion 634. The reciprocating screw 631 is movably connected to the cleaning roller 63. The inner wall of the housing 1 is connected to the inner wall of the housing 1. The moving plate 632 is fixedly connected to the front end of the reciprocating screw 631, the guide rod 633 is fixedly connected to both ends of the moving plate 632, and the protrusion 634 is fixedly connected to the center of the moving plate 632. The surface of the protrusion 634 after moving is in contact with the inner wall of the housing 1. The surface of the cleaning roller 63 is rotatably connected to the inner wall of the fixed disk 61. The surface of the guide rod 633 is slidably connected to the inner wall of the fixed disk 61. The surface of the pulley 62 is in contact with the inner wall of the housing 1. The rotation of the cleaning roller 63 will drive the reciprocating screw 631 guided by the guide rod 633 to move back and forth. The reciprocating screw 631 will drive the protrusion 634 on the moving plate 632 to repeatedly knock the inner wall of the housing 1, thereby shaking off the impurities on the inner wall of the housing 1 and further improving the cleaning effect.

[0026] Working principle: After the centrifuge is used, the top cover 2 is opened and the inner cylinder 3 is taken out. Then, the rotating plate 51 is installed on top of the motor 5 and water is added for cleaning. At this time, the motor 5 starts and drives the rotating plate 51 to rotate clockwise. The rotating plate 51 drives the transmission rod 53 on the roller 52 to rotate. The transmission rod 53 drives the scraper 54 to clean and remove impurities from the inner wall of the shell 1. At the same time, when the roller 52 is driven, it will contact the inner wall of the shell 1 and drive the roller 52 to rotate. The roller 52 will drive the scraper 54 on the transmission rod 53 to rotate, so that the scraper 54 further scrapes and cleans the inner wall of the shell 1, improving the cleaning effect.

[0027] When the rotating plate 51 rotates, it drives the fixed plate 61 to rotate. The fixed plate 61 drives the pulley 62 to rotate. The pulley 62 contacts the housing 1 and is driven to rotate by itself. The pulley 62 drives the cleaning roller 63 to rotate. The cleaning roller 63 further cleans the bottom wall inside the housing 1, improving the cleaning effect of the centrifuge. At the same time, the rotation of the cleaning roller 63 drives the reciprocating screw 631, which is guided by the guide rod 633, to move back and forth. The reciprocating screw 631 drives the protrusion 634 on the moving plate 632 to repeatedly knock the inner wall of the housing 1, thereby shaking off the impurities on the inner wall of the housing 1 and further improving the cleaning effect.

[0028] Please see Figure 4-8Based on the above embodiments, in another embodiment of the present invention, the agitating device 7 includes a transmission plate 71, a rotating ring 72, an elastic arc plate 73, a push rod 74, and an elastic plate 75. The transmission plate 71 is fixedly connected to the top of the fixed disk 61, the rotating ring 72 is movably connected to the inner wall of the transmission plate 71, the two sides of the elastic arc plate 73 are fixedly connected to the inner wall of the rotating ring 72, the elastic plate 75 is fixedly connected to the surface of the transmission plate 71, and the push rod 74 is fixedly connected to the bottom of the elastic plate 75. When the fixed disk 61 rotates, it drives the transmission plate 71 to rotate. The movable plate 71 agitates the water flow in the housing 1, enhancing the cleaning effect on the interior of the housing 1. Simultaneously, the rotation of the pulley 62 drives the rotating ring 72 in contact with it to rotate. The rotating ring 72 moves along the inner wall of the transmission plate 71. When the rotating ring 72 moves the elastic arc plate 73 to the transmission plate 71, the transmission plate 71 limits the elastic arc plate 73, causing the arched elastic arc plate 73 to press into the inner wall of the rotating ring 72. After the elastic arc plate 73 passes the transmission plate 71, under the action of elasticity, the elastic arc plate 73 will arch again and push the upper push rod 74 upwards. As the push rod 74 moves, it pushes the elastic plate 75 upward, causing the elastic plate 75 to arch and further agitate the water flow. The agitation device 7 also includes an arc-shaped rod 751 and an elastic telescopic plate 752. The arc-shaped rod 751 is rotatably connected to the inner wall of the rotating ring 72 via a torsion spring, and the elastic telescopic plate 752 is rotatably connected to the inner wall of the elastic plate 75 via a torsion spring. The surface of the arc-shaped rod 751 is in contact with the surface of the elastic telescopic plate 752. The bottom of the rotating ring 72 is in contact with the surface of the pulley 62, and the upper surface of the elastic arc plate 73 is away from the push rod 74. One end of the plates 75 is in contact with each other. The upper surface of the elastic arc plate 73 after it moves is in contact with the inner wall of the transmission plate 71. When the rotating ring 72 drives the arc rod 751 to move to the transmission plate 71, the transmission plate 71 will push the arc rod 751 to rotate into the rotating ring 72. When the arc rod 751 passes the transmission plate 71, the torsion spring will drive the arc rod 751 to rotate out of the rotating ring 72 and push the elastic telescopic plate 752 to rotate. The elastic telescopic plate 752 will push the water flow towards the inner wall of the shell 1, so that the water flow impacts the inner wall of the shell 1 and washes away the impurities adhering to the surface.

[0029] The unblocking device 8 includes a turntable 81, a spiral sleeve 82, a pressure rod 83, and a limiting plate 84. The turntable 81 is rotatably connected to the top of the rotating plate 51. The spiral sleeve 82 is movably connected to the inner wall of the turntable 81. The pressure rod 83 is movably connected to the inner wall of the spiral sleeve 82. The limiting plate 84 is fixedly connected to the top of the pressure rod 83. When the roller 52 rotates, it drives the turntable 81, which is in contact with it, to rotate. The turntable 81 drives the spiral sleeve 82 to rotate through the locking block on its inner wall and the cross spiral groove on the spiral sleeve 82. However, the spiral sleeve 82 is limited by the rotating plate 51 and can only move. Therefore, the turntable 81 drives the spiral sleeve 82 to move up and down reciprocally. When the spiral sleeve 82 moves down, it drives the spring to pull the limiting plate 84 down, thus limiting its movement. The disc 84 will drive the pressure rod 83 to move downward. When the pressure rod 83 moves to the discharge pipe 4, it will extend into the discharge pipe 4 and clear its interior to prevent impurities from clogging the discharge pipe 4. A spring is provided between the limiting disc 84 and the spiral sleeve 82. The surface of the spiral sleeve 82 is provided with a cross spiral groove. The inner wall of the turntable 81 is provided with a locking block, which is located in the cross spiral groove. The surface of the turntable 81 is in contact with the surface of the roller 52. The surface of the spiral sleeve 82 is slidably connected to the inner wall of the rotating plate 51. When the pressure rod 83 continues to move, the spiral sleeve 82 will move upward and push the pressure rod 83 upward through the spring and the limiting disc 84, so that the pressure rod 83 moves out of the discharge pipe 4 for easy clearing next time.

[0030] Working principle: When the fixed disk 61 rotates, it drives the transmission plate 71 to rotate. The transmission plate 71 agitates the water flow in the housing 1, improving the cleaning effect of the water flow on the inside of the housing 1. At the same time, when the pulley 62 rotates, it drives the rotating ring 72 in contact with it to rotate. The rotating ring 72 moves on the inner wall of the transmission plate 71. When the rotating ring 72 drives the elastic arc plate 73 to move to the transmission plate 71, the transmission plate 71 limits the elastic arc plate 73, causing the arched elastic arc plate 73 to press into the inner wall of the rotating ring 72. After the elastic arc plate 73 passes the transmission plate 71, the elastic arc plate 73 will arch again under the action of elasticity. The top rod 74 is pushed upwards, which in turn pushes the elastic plate 75 upwards, causing the elastic plate 75 to arch and further agitate the water flow. At the same time, when the rotating ring 72 moves the arc rod 751 to the transmission plate 71, the transmission plate 71 pushes the arc rod 751 to rotate into the rotating ring 72. When the arc rod 751 passes the transmission plate 71, the torsion spring will drive the arc rod 751 to rotate out of the rotating ring 72 and push the elastic telescopic plate 752 to rotate. The elastic telescopic plate 752 will push the water flow towards the inner wall of the housing 1, causing the water flow to impact the inner wall of the housing 1 and wash away the impurities adhering to the surface.

[0031] When roller 52 rotates, it drives turntable 81, which is in contact with it, to rotate. Turntable 81 drives spiral sleeve 82 to rotate through the locking block on the inner wall and the cross spiral groove on spiral sleeve 82. However, spiral sleeve 82 is limited by rotating plate 51 and can only move. Therefore, turntable 81 drives spiral sleeve 82 to move up and down back and forth. When spiral sleeve 82 moves down, it drives spring to pull limit plate 84 down. Limit plate 84 drives pressure rod 83 down. When pressure rod 83 moves to discharge pipe 4, pressure rod 83 will extend into discharge pipe 4 and clear its interior to prevent impurities from clogging discharge pipe 4. When pressure rod 83 continues to move, spiral sleeve 82 moves up and pushes pressure rod 83 up through spring and limit plate 84, so that pressure rod 83 moves out of discharge pipe 4 for easy clearing next time.
