Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of centrifuges, in particular to a rotating basket of a vertical centrifuge. Background Art
[0002] The centrifuge basket (i.e., screen basket) is mainly composed of an upper flange, a lower flange, reinforcement ribs, a reinforcement ring, and a stainless steel conical mesh cylinder. The stainless steel conical mesh cylinder is welded together by several fan-shaped screens. The fan-shaped screen is made of stainless steel wire rolled into a special shape of screen bars and support bars welded together by special equipment. The screen bars are arranged along the conical generatrix of the screen basket.
[0003] The centrifuge rotates at high speed during operation. Since the basket not only has to withstand vibration loads, but also has to withstand severe erosion from materials and water, the basket in the centrifuge is a wearing part that needs to be replaced frequently.
[0004] In order to save replacement costs, the existing device replaces the stainless steel conical mesh cylinder formed by welding several fan-shaped screens with several spaced partitions and screening mesh panels arranged between the partitions. Currently, the top and bottom of the screening mesh panels are plugged into the upper and lower flanges respectively, and the upper and lower ends of the partition panels are fixed to the upper and lower flanges respectively to achieve the installation of the rotating basket. However, the following problems still exist in this process:
[0005] 1. During screening, larger materials will remain on the inner wall of the rotating basket, thereby clogging the screening mesh and affecting the subsequent centrifugal screening of the materials;
[0006] 2. The screening mesh panels are mainly fixed by plugging the top and bottom into the upper flange and the lower flange respectively. However, during the screening process, on the one hand, there is a possibility that the material may leak into the rotating basket from the gap between the screening mesh panel group and the partition plate. On the other hand, if the screening mesh panels are only fixed by the upper and lower sides, the left and right sides of the screening mesh panel group may be warped due to deformation after long-term use, which may easily cause the user to collide or rub with the warped parts during operation and cause injury. Utility Model Content
[0007] In order to solve the above problems, the purpose of the present invention is to provide a vertical centrifuge basket, which can clean the inner wall of the basket during centrifugation, thereby avoiding as much as possible the residue of larger materials on the inner wall of the basket during screening.
[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0009] A vertical centrifuge basket includes an upper flange and a lower flange arranged in parallel, a plurality of partition plates evenly fixed between the upper flange and the lower flange, a plurality of detachable screening components arranged between any two adjacent partition plates, and a cleaning component mounted around the upper flange and arranged along the length direction of any one of the partition plates; the cleaning component includes a mounting ring fixed around the interior of the upper flange, a guide ring fixed around the bottom of the mounting ring, a gear ring fixed around the outer wall of the guide ring, an annular slide rail arranged around the interior of the guide ring on the lower surface of the mounting ring, a slider slidably connected to the annular slide rail, a gear rotatably arranged on the lower surface of the slider and meshing with the outer side of the gear ring, and a cleaning roller fixed to the lower surface of the gear and with its outer wall abutting against the inner wall of the screening component.
[0010] More preferably, each group of screening components includes two limit rods, a screening mesh group fixed between the two limit rods, and a pair of plug-in plates symmetrically arranged on the upper and lower sides of the screening mesh group; the outer walls on both sides of the partition plate are provided with limit grooves adapted to the limit rods along the height direction, and the upper flange and the lower flange are provided with a plurality of first plug-in grooves and a second plug-in groove adapted to the plug-in blocks in the plurality of screening components on the opposite side.
[0011] More preferably, the cleaning roller is arranged obliquely outward from top to bottom.
[0012] More preferably, the screening mesh plate includes two screening mesh plates that are parallel and closely arranged.
[0013] More preferably, both ends of the partition plate are fixed to the upper flange and the lower flange respectively by bolts.
[0014] The utility model has the following beneficial effects:
[0015] 1. The utility model meshes with the gear ring, and while driving the gear to rotate, the gear will drive the slider and the cleaning roller to slide along the annular slide rail, so that the cleaning roller can clean the inner wall of multiple screening components, so as to avoid as much as possible that larger materials remain on the inner wall of the rotating basket during screening, affecting the subsequent centrifugal screening of materials;
[0016] 2. The utility model cooperates with the corresponding limiting grooves of the two adjacent partition plates through two limiting rods. On the one hand, it minimizes the possibility of materials leaking into the rotating basket from the gap between the screening mesh plate group and the partition plate during the screening process. On the other hand, it also enhances the stability of the screening mesh plate group, and avoids the possibility of the left and right sides of the screening mesh plate group tilting due to deformation of the screening mesh plate group after long-term use.

[0022] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments.
[0023] A vertical centrifuge basket includes an upper flange 1 and a lower flange 2 arranged in parallel, a plurality of partition plates 3 evenly fixed between the upper flange 1 and the lower flange 2, a plurality of screening components 4 detachably arranged between any two adjacent partition plates 3, and a cleaning component 5 mounted around the upper flange 1 and arranged along the length direction of any one of the partition plates 3; the cleaning component 5 includes a mounting ring 51 fixed around the interior of the upper flange 1, a guide ring 52 fixed around the bottom of the mounting ring 51, a gear ring 53 fixed around the outer wall of the guide ring 52, an annular slide rail 54 arranged around the interior of the guide ring 52 on the lower surface of the mounting ring 51, a slider 55 slidably connected to the annular slide rail 54, a gear 56 rotatably arranged on the lower surface of the slider 55 and meshing with the outer side of the gear ring 53, and a cleaning roller 57 fixed to the lower surface of the gear 56 and with its outer wall abutting the inner wall of the corresponding screening component 4.
[0024] Through the engagement of the gear ring 53 and the gear 56, the gear 53 drives the slider 55 and the cleaning roller 57 to slide along the annular slide rail 54 while driving the gear 53 to rotate, so that the cleaning roller 57 can clean the inner wall of the multiple groups of screening components 4 to avoid as much as possible that larger materials remain on the inner wall of the rotating basket during screening, affecting the subsequent centrifugal screening of materials.
[0025] As a possible implementation of this scheme, preferably, each group of the screening components 4 includes two limiting rods 41, a screening mesh panel group 42 fixed between the two limiting rods 41, and a pair of plug-in plates 43 symmetrically arranged on the upper and lower sides of the screening mesh panel group 42; the outer walls on both sides of the partition plate 3 are provided with limiting grooves 31 adapted to the limiting rods 41 along the height direction, and the upper flange 1 and the lower flange 2 are respectively provided with a plurality of first plug-in grooves 11 and second plug-in grooves 21 adapted to the plug-in blocks in the plurality of screening components 4 on opposite sides; By cooperating with the corresponding limiting grooves 31 of the two adjacent partition plates 3, the two limiting rods 41 can, on the one hand, minimize the possibility of materials leaking into the rotating basket from the gap between the screening mesh panel group 42 and the partition plate 3 during the screening process. On the other hand, the stability of the screening mesh panel group 42 is enhanced, and the possibility of the left and right sides of the screening mesh panel group 42 tilting due to deformation of the screening mesh panel group 42 after long-term use is avoided as much as possible, further reducing the possibility of user injury due to the tilting of the left and right edges of the screening mesh panel group 42, thereby improving the safety of the device.
[0026] As a possible implementation of this scheme, preferably, the cleaning roller 57 is arranged to be tilted outward from top to bottom; this allows one side of the outer surface of the cleaning roller 57 to always remain in contact with the inner wall of the corresponding screening mesh group 42, thereby improving the cleanliness of cleaning.
[0027] As a possible implementation of this solution, preferably, the screening mesh plate 421 includes two screening mesh plates 421 that are parallel and closely arranged; this can avoid the possibility that the material will be exposed from the rotating basket when one of the screening mesh plates 421 is damaged.
[0028] As a possible implementation of this solution, preferably, both ends of the partition plate 3 are fixed to the upper flange 1 and the lower flange 2 respectively by bolts 6 .
[0029] The working principle of this device is:
[0030] When the screening mesh panel group 42 needs to be replaced, first remove the bolts 6, then remove the upper flange 1 and the lower flange 2 from the top and bottom respectively, so that the plug-in plate 43 of each screening mesh panel group 42 is moved out from the corresponding first plug-in slot 11 or the second plug-in slot 21, and then move the screening mesh panel group 42 downward so that the limiting rods 41 on both sides are disengaged from the corresponding limiting slots 31. At this time, the replacement of the screening mesh panel group 42 is completed. After replacement, the partition plate 3 is fixed to the upper flange 1 by the bolts 6, and then removed from Insert the screening mesh panel group 42 upward between the two partition plates 3 until the plug-in plate 43 located above the screening mesh panel group 42 is inserted into the first plug-in slot 11 and the two limit rods 41 are respectively in contact with the slot walls of the plug-in slot 21 on the opposite side of the two partition plates 3. Finally, align the second plug-in slot 21 of the lower flange 2 with the corresponding plug-in plate 43, and then fix the partition plate 3 to the lower flange with the bolts 6. In order to improve the stability of the device, a reinforcement ring and reinforcement ribs (not shown) can be provided around the outside of the screening component 4.
