DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1: Please refer to Figure 1-9 A vertical centrifuge comprises a centrifuge base 1, a barrel 2 is fixedly arranged above the centrifuge base 1, a filtering device 3 is movably arranged inside the barrel 2, and a collecting device 5 is fixedly arranged inside the barrel 2; The filtering device 3 includes a rotating drum 31 movably arranged inside the barrel 2, and filtering holes 32 are formed around the inside of the rotating drum 31. A cleaning device 4 is fixedly arranged outside the rotating drum 31, and the cleaning device 4 rotates with the rotation of the rotating drum 31. The cleaning device 4 includes a plurality of evenly distributed columns 41 fixedly arranged on the outer wall of the drum 31, and outer connecting columns 42 are movably connected between adjacent columns 41. A cleaning device 43 is provided on the side of the outer connecting column 42 close to the drum 31. When the drum 31 rotates to filter the raw materials, the columns 41 will rotate with the drum 31 to generate centrifugal force. The centrifugal force causes the columns 41 to drive the outer connecting columns 42 and the cleaning device 43 to move upward, thereby causing the cleaning device 43 to scrape and clean the residues on the inner wall of the drum 31 and the filter holes 32, so that the residues fall into the collecting device 5. Specifically, when the centrifuge is running, the drum 31 starts to rotate in the barrel 2, and the column 41 is fixedly installed on the outside of the drum 31, and then the column 41 rotates with the drum 31, and the outer connecting column 42 is installed between adjacent columns 41, so that the outer connecting column 42 moves upward along the outer wall of the drum 31 under the action of the centrifugal force of the drum 31, and then the cleaning device 43 connected to it is driven by the outer connecting column 42 to move upward along the inner wall of the drum 31 until the speed of the drum 31 is constant. At this time, it moves to the top of the filter hole 32, and then the staff adds the material into the barrel 2, and the material is thrown onto the inner wall of the drum 31 for cleaning. During centrifugal dehydration, the water in the material passes through the filter holes 32 and is thrown out by the drum 31, and the material residue remains on the inner wall of the drum 31, thereby separating the material from the solid and the liquid; when the material is dehydrated, the rotation speed of the drum 31 begins to decrease and rotates at a low speed, and then the outermost layer of the material is scraped off first, and the rotation speed of the drum 31 decreases, resulting in a smaller centrifugal force, and then under the action of gravity, the external connecting column 42 and the cleaning device 43 move downward along both sides of the drum 31 respectively until the drum 31 stops rotating, at which time the cleaning device 43 removes the solid residue remaining on the inner wall of the drum 31 and the filter holes 32, and drops it into the collection device 5 for removal; The vertical centrifuge is provided with a cleaning device 43 inside the drum 31, so that during the centrifugal process of the drum 31 rotating at a uniform speed, the cleaning device 43 generates an upward centrifugal force, and the centrifugal force causes the cleaning device 43 to move upward along the inner wall of the drum 31, and then the cleaning device 43 scrapes and cleans the residues on the inner wall of the drum 31 and the filter holes 32, causing them to fall into the collecting device 5, thereby solving the problem of excessive solid materials remaining inside the drum 31 and causing material waste.

[0022] Example 2: See Figure 1-Figure 9, which is different from the above-mentioned embodiment, the cleaning device 43 includes an inner wall scraper 432, which is located in the drum 31 and fits against the inner wall of the drum 31, and a plurality of evenly distributed inner groove scrapers 431 are fixed between the inner wall scraper 432 and the external connecting column 42, and the plurality of inner groove scrapers 431 are respectively inserted into each filter hole 32, and evenly distributed lower inserting knives 433 are fixed to the bottom of the inner wall scraper 432, and evenly distributed upper inserting knives 434 are fixed to the top of the inner wall scraper 432, and the inner wall scraper 432 moves with the external connecting column 42, and scrapes up and down along the inner wall of the drum 31, and removes the residue on the inner wall to the inside of the barrel 2; The lower inserting knife 433 corresponds to the upper inserting knife 434 in position, and both are staggered with the position of the filter holes 32. The height of the lower inserting knife 433 and the upper inserting knife 434 is the same as the spacing between two upper and lower adjacent filter holes 32. When the inner wall scraper 432 moves up and down, the lower inserting knife 433 and the upper inserting knife 434 will loosen the residues between the multiple groups of filter holes 32, and then be thrown into the barrel 2 by the rotating drum 31; Specifically, when the drum 31 rotates centrifugally at a uniform speed, the cleaning device 43 follows the external connecting column 42 and moves upward to the top of the filter hole 32 until the dehydration of the drum 31 is completed. At this time, the rotation speed of the drum 31 begins to decrease, resulting in a decrease in the upward centrifugal force of the external connecting column 42 and the cleaning device 43. Then, under the action of their own gravity, the external connecting column 42 and the cleaning device 43 move downward along both sides of the drum 31 respectively until the drum 31 stops rotating. In this process, the multiple groups of lower inserting knives 433 first poke the fixed residues remaining on the inner side of the drum 31 loose, so that the residues are loosened from the inner wall of the drum 31, and then The inner wall scraper 432 moves along the path poked loose by the multiple groups of lower inserting knives 433 to remove the loose residues on the inner wall of the drum 31 until the inner wall scraper 432 is located at the bottom of the filter hole 32. At this time, the lower inserting knife 433 at the bottom of the inner wall scraper 432 continues to poke downward to loosen the residues between the multiple groups of filter holes 32, and then the drum 31 is started again to rotate until the rotation speed of the drum 31 is the same as the centrifugal rotation speed. At this time, the drum 31 will throw the loose residues on its inner wall into the barrel 2, and the inner wall scraper 432 will scrape upward along the inner wall of the drum 31 again under the action of centrifugal force, so as to remove the residues on the inner wall of the drum 31.

[0023] Example 3: See Figure 1-Figure 9 , which is different from the above-mentioned embodiment, the column 41 includes a hollow cylinder 411 fixedly arranged on the outside of the drum 31, and eccentric limit slots 414 are provided on both sides of the hollow cylinder 411. An elastic telescopic column 412 is fixedly arranged inside the hollow cylinder 411, and the elastic telescopic column 412 is parallel to the eccentric limit slot 414. A connecting piece 413 is fixedly connected between the bottom end of the elastic telescopic column 412 and the end of the external connecting column, and the connecting piece 413 is plugged into the eccentric limit slot 414; The eccentric limiting slot 414 is configured as an inclined strip hole, and the distance between the bottom end of the eccentric limiting slot 414 and the center of the drum 31 gradually increases from the top end thereof; The bottom of the inner groove scraper 431 is provided with two oppositely arranged tips, and the inner wall scraper 432 is provided with two vertically symmetrical slopes; The elastic telescopic column 412 includes an outer hollow cylinder and an inner hollow cylinder. One end of the inner hollow cylinder is movably inserted into the outer hollow cylinder. A spring is fixedly connected between the inner bottom wall of the inner hollow cylinder and the inner top wall of the outer hollow cylinder. When the rotating drum 31 stops rotating, the elastic telescopic column 412 provides a downward elastic force to the outer connecting column 42 and the cleaning device 43, so that the cleaning device 43 can move downward stably and scrape the residue on the inner wall of the rotating drum 31. Specifically, when the drum 31 starts to be centrifuged at a uniform speed, since the elastic telescopic column 412 is parallel to the eccentric limiting slot 414, and the distance from the bottom end to the top end of the eccentric limiting slot 414 and the center of the drum 31 gradually increases, the drum 31 rotating at a uniform speed will generate an upward centrifugal force on the external connecting column 42 on its outer wall, the connecting pieces 413 at both ends of the external connecting column 42, and the elastic telescopic column 412 connected to one end of the connecting piece 413. First, the external connecting column 42 moves upward along the outer wall of the drum 31 under the action of the centrifugal force, and then the external connecting column 42 drives the connecting piece 413 to move upward along the eccentric limiting slot 414, so that the connecting piece 413 drives one end of the elastic telescopic column 412 to move upward, so that it squeezes the spring inside the elastic telescopic column 412, until the drum 31 is centrifuged at a uniform speed, at which time the external connecting column 42 and the inner groove scraper 431 move to the top of the filter hole 32; When the drum 31 is centrifuged at a constant speed, the material is centrifuged at a high speed by the drum 31, resulting in a tight bond between the material and the inner wall of the drum 31. When the drum 31 is scraped at a low speed, the gravity of the external connecting column 42 and the cleaning device 43 cannot make the cleaning device 43 move downward along the inner wall of the drum 31 to scrape the material. At this time, the elastic telescopic column 412 provides elastic force to the external connecting column 42 and the cleaning device 43 connected to one end thereof. During the period of scraping the material at a low speed by the drum 31, the elastic force of the elastic telescopic column 412 enables the external connecting column 42 to move downward along the inner wall of the drum 31 to scrape the material. By moving downward steadily, the outer connecting column 42 drives the inner wall scraper 432 connected thereto to move downward steadily along the inner wall of the drum 31 to scrape the material. At the same time, the two oppositely arranged tips at the bottom of the inner groove scraper 431 reduce the friction between it and the material, so that the inner groove scraper 431 can scrape off the material residue remaining on the inner wall of the filter hole 32, and the two upper and lower symmetrical slopes arranged on the inner wall scraper 432 make it easy for the inner wall scraper 432 to separate the material on the inner wall of the drum 31 from the inner wall of the drum 31.

[0024] Example 4: See Figure 1-Figure 9, which is different from the above-mentioned embodiment, the collecting device 5 includes a collecting cover 51 arranged at the bottom of the drum 31, a driving motor 57 is fixedly arranged at the bottom of the collecting cover 51, the top of the collecting cover 51 is movably connected to the drum 31, a connecting ring 53 is arranged inside the drum 31, a plurality of connecting columns 54 distributed in a circular array are fixedly connected between the outer wall of the connecting ring 53 and the inner wall of the drum 31, and the connecting ring 53 is connected to the output end of the driving motor 57; The inner bottom of the collecting cover 51 is fixedly provided with an inclined plate 52 located outside the connecting swivel 53. The connecting swivel 53 is rotatably connected to the inclined plate 52. A discharge pipe 56 is fixedly provided at the bottom of the collecting cover 51. The discharge pipe 56 is located at the lowest point of the inclined plate 52. The centrifuge base 1 includes a support frame 11, a support bottom plate 12 is fixedly provided above the support frame 11, an information processor 13 located on one side of the barrel 2 is fixedly provided above the support bottom plate 12, a servo motor 14 located on one side of the information processor 13 is fixedly provided on the top of the support bottom plate 12, a telescopic push rod 15 located on both sides of the servo motor 14 is movably provided on the top of the support bottom plate 12, and a connecting plate 16 is fixedly provided at one end of the top of the telescopic push rod 15; The barrel 2 includes a centrifuge housing 21 disposed on the supporting bottom plate 12, a top cover 24 is movably disposed on the top of the centrifuge housing 21, a watering rod 22 located outside the drum 31 is fixedly disposed inside the centrifuge housing 21, a throwing assembly 25 and a feed pipe 26 are disposed on the top of the top cover 24, a scraping assembly 27 located on one side of the feed pipe 26 is fixedly disposed on the top of the top cover 24, a monitoring assembly 28 is fixedly disposed on the bottom of the top cover 24, a drain pipe 17 located on one side of the drive motor 57 is fixedly disposed on the bottom of the centrifuge housing 21, and an inclined plate 52 located outside the connecting swivel 53 is fixedly disposed inside the collecting cover 51; Specifically, the telescopic push rod 15 is controlled to telescope upward, so that the connecting plate 16 connected to one end thereof is turned downward, so that the top cover 24 connected to one end of the connecting plate 16 is covered on the top of the centrifuge housing 21, and then the connecting lock buckle 29 of the centrifuge housing 21 and the outer side of the top cover 24 is locked, so that the connection between the centrifuge housing 21 and the top cover 24 is more tightly and firmly connected. After the top cover 24 is closed, the feeding structure and the throwing assembly 25 are started. At this time, the material enters the centrifuge housing 21 from the feeding pipe 26 and falls between the bottom of the throwing assembly 25 and the material receiving chassis 55. At this time, the motor at one end of the throwing assembly 25 is started to rotate and throw the entered material along the gap between the bottom of the throwing assembly 25 and the top of the material receiving chassis 55, and then the rotating and thrown material adheres to the inner wall of the drum 31. At the same time, the driving motor 57 Start, the driving motor 57 drives the connecting ring 53 at one end thereof and the connecting column 54 at its outer side to rotate, and then the connecting column 54 drives the drum 31 connected at one end thereof to rotate, so that the drum 31 rotates and centrifuges inside the centrifuge housing 21, so that when the materials that are rotated and scattered from the gap between the bottom of the throwing assembly 25 and the top of the receiving chassis 55 hit the rotating drum 31, the materials will be crushed by the rotating drum 31, and the crushed drum 31 will be separated into fixed residues and liquid, and the rotating drum 31 makes the solid residues in the materials adhere to the inside of the drum 31, and the liquid in the materials will pass through the filter holes 32 evenly opened on the surface of the drum 31, splash on the inner wall of the centrifuge housing 21, and then fall to the bottom of the centrifuge housing 21 along the inner wall under the action of gravity, and finally be discharged from the drain pipe 17 at the bottom of the centrifuge housing 21; When the drum 31 is centrifuged at a constant speed, the monitoring component 28 inside the centrifuge housing 21 will monitor the thickness of the accumulated materials inside the drum 31 in real time. When the thickness reaches the expected thickness, the material is stopped from being added to the feed pipe 26, and the drum 31 will continue to transport and centrifuge for a period of time until the innermost layer of moisture accumulated in the drum 31 is removed by the rotation of the drum 31, and then the rotation speed of the drum 31 is reduced to make it rotate at a low speed. At this time, the external connecting column 42 falls along the filter hole 32 and is located above the middle of the filter hole 32. Then, the watering rod 22 is controlled to spray and soak the materials on the inside of the drum 31. After the wetting is completed, the drum 31 is accelerated to accelerate it to the centrifugal speed, and then the solid materials inside the drum 31 are dehydrated for a second time. At this time, the external connecting column 42 moves back to the top of the filter hole 32 under the centrifugal force of the drum 31. After the dehydration of the solid materials inside the drum 31 is completed, the rotation speed is reduced again. The speed of the drum 31 is controlled, and then the scraper assembly 27 is started, so that the scraper on the outside slowly rotates toward the inside of the drum 31, and then the scraper scrapes the material on the surface of the drum 31 at a uniform speed until the scraper on the outside of the scraper assembly 27 rotates to a set angle. At this time, the fixed material remaining in the drum 31 cannot be cleaned by the scraper on the outside of the scraper assembly 27. Then the scraper assembly 27 is controlled to retract the scraper, and the solid material falling from the inside of the drum 31 will pass through the connecting column 54 and fall on the top of the inclined plate 52, and the top of the inclined plate 52 is an inclined surface, so that the material falling on it will automatically enter the discharge pipe 56 along the inclined surface of the inclined plate 52, so as to be discharged and collected. After the collection is completed, the sprinkler rod 22 is restarted to flush the inside of the centrifuge housing 21, the inside and outside sides of the drum 31 and the inner side of the filter hole 32, and the flushed water will be discharged from the discharge pipe 56 and the drain pipe 17.
