Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a suspended rotating basket. Background Technology

[0002] In industrial cleaning equipment, rotating baskets are used to carry and rotate the washing basket within the equipment, ensuring that the cleaning solution thoroughly rinses the objects to be cleaned, achieving a complete cleaning effect. Currently widely used rotating baskets typically have the following structure: Figure 1 As shown, it mainly includes a rear flange 1 and a front flange 2. The front flange 2 is typically equipped with multiple end bearings, such as end bearing 1 21, end bearing 22, end bearing 3 23, and end bearing 4 24. End bearings 1 21, 22, 3, and 4 directly engage with the fixed flange (not shown) on the cleaning equipment cavity. During operation, the weight and load of the entire rotating basket are primarily transferred to the equipment cavity through these end bearings, and the rotation of the basket is achieved by the rolling motion of the bearings.

[0003] The above-mentioned installation method of the end bearing has the following problems: such as Figure 1 As shown, plane a represents the highest working level of the cleaning fluid during the cleaning process. In the above design, end bearings 1 (21), 22, 3 (23), and 4 (24) are all located below the highest level plane a. This means that during each cleaning cycle, these end bearings are immersed for an extended period in a corrosive environment containing chemical cleaning agents and disinfectants. The cleaning fluid inevitably penetrates the bearing seals, and the chemical reagents cause chemical corrosion to the bearing raceways, rolling elements, and cage. The root cause of the problem is the unreasonable design of the bearing installation position, directly exposing them to the working environment of the cleaning fluid. Frequent bearing damage necessitates frequent downtime for replacement, resulting in high maintenance costs and severely impacting equipment efficiency.

[0004] Therefore, it is urgent to fundamentally overcome the problem of short bearing life caused by the long-term immersion of end bearings in cleaning fluid in traditional rotating baskets. It is also necessary to adjust the installation method of the rotating bearings on the rotating baskets to avoid corrosion of the bearing components by the cleaning fluid. Utility Model Content

[0005] The purpose of this invention is to fundamentally overcome the problem of short bearing life caused by the long-term immersion of the end bearings in cleaning solution in traditional rotating baskets.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a suspended rotating basket. The system includes a rear flange and a front flange connected to the rear flange. A first roller group and a second roller group are provided between the rear flange and the front flange. At least one guide rod is provided on the upper outer side of each of the first roller group and the second roller group. One end of the guide rod is connected to the rear flange and the other end is connected to the front flange through an adapter flange. The front flange is provided with a rotating basket hoisting assembly for rotatably suspending the entire rotating basket in the cleaning equipment cavity. The rotating basket hoisting assembly is located at the top of the front flange, and the bottom of the rotating basket hoisting assembly is above the liquid level plane of the rotating basket. The rotating basket hoisting assembly includes a first fixing plate and a second fixing plate. The first fixing plate is fixedly connected to the cleaning equipment cavity. The top of the first fixing plate and the second fixing plate are connected by multiple fourth connecting columns. The bottom of the first fixing plate is connected to the front flange through multiple bearings. The front flange is locked between the rotating sides of the multiple bearings and the multiple fourth connecting columns and rotates relative to the first fixing plate through the multiple bearings.

[0007] Preferably, the first and second fixing plates of the rotating basket hoisting assembly are fixed to each other in parallel and spaced apart by three fourth connecting columns, which are arranged in an arc shape.

[0008] Preferably, the plurality of bearings on the first fixed plate includes a first bearing, a second bearing, and a third bearing arranged in an arc.

[0009] Preferably, the first roller group includes a first roller plate and a plurality of first rollers rotatably connected to the first roller plate; the second roller group includes a second roller plate and a plurality of second rollers rotatably connected to the second roller plate; the rolling surfaces of the first rollers and the second rollers together form a track for conveying the washing basket into the interior of the rotating basket.

[0010] Preferably, a first limiting rod and a second limiting rod are also fixed on the rear flange. The first limiting rod and the second limiting rod are set at the same height, and the bottom of the first limiting rod and the second limiting rod is the highest working liquid level of the cleaning fluid.

[0011] Preferably, the other ends of the first and second limiting rods are connected to the front flange via a support rod; the support rod is connected to the front flange via a third connecting column.

[0012] Preferably, after the rotating basket is installed in the cleaning equipment, the bottom of the lowest bearing is positioned above the highest working level of the cleaning fluid.

[0013] Compared with existing technologies, the advantages and positive effects of this invention are as follows: By moving the end bearing, which bears the main rotational support function, from the traditional front flange side position to the top of the front flange, and ensuring that the bearing installation position is always above the highest level of the cleaning fluid using the rotating basket lifting assembly, the bearing is removed from the corrosive and immersion environment. The bearing on the rotating basket lifting assembly operates in a dry and clean environment, and its internal lubricant can remain effective for a long time, avoiding chemical corrosion and wear. This significantly extends the service life of the bearing. Due to the extended bearing life, the replacement frequency decreases. Maintenance work changes from frequent bearing replacement to regular inspection, saving a significant amount of bearing and labor costs.

[0014] The rotating basket hoisting assembly uses multiple bearings. The first, second, and third bearings, arranged in an arc shape, also form a triangular structure, providing stable support for the rotation axis of the front flange and enhancing the stability of the rotating basket. In addition, the first and second limit rods on the rear flange and the transition flange provide axial constraints for the washing basket. Together with the guide rods on the side of the washing basket and the first and second roller groups, they provide a constraint space for the washing basket, allowing it to rotate stably with the rotating basket.

Detailed Implementation

[0016] The main technical solutions of the existing technology are as follows Figure 1 As shown: There are multiple guide shafts between the front flange 2 and the rear flange 1. The end of the front flange 2 facing away from the rear flange 1 is equipped with end bearings 21, 22, 23, and 24. These end bearings engage with the flanges of the cleaning chamber. During operation, the basket rotates thanks to the support and rolling action of these bearings. When the equipment is working, the cleaning fluid in the cleaning chamber comes into contact with the end bearings. Because the basket is constantly rotating, the highest points of the end bearings 21, 22, 23, and 24 are always below the highest level of the cleaning fluid. Figure 1 The mid-level plane 'a' represents the highest level of the cleaning fluid. End bearings 1 (21), 22, 23, and 24 are all located below plane 'a' and will be immersed in the cleaning fluid for extended periods, leading to frequent bearing damage and shortened lifespan. Reduced bearing lifespan necessitates frequent equipment shutdowns for replacement.

[0017] The main purpose of this invention is to change the installation method of the front flange 2 of the rotating basket in order to extend the service life of the bearing. The root cause of the problem is the unreasonable installation position of the bearing, which is directly exposed to the working environment of the cleaning fluid. Therefore, in order to fundamentally overcome the working condition of the traditional rotating basket where the end bearing is immersed in the cleaning fluid for a long time, the bearing position should be raised above the highest liquid level a of the cleaning fluid.

[0018] like Figure 2As shown, this utility model discloses a hoisting rotating basket, including a rear flange 1 and a front flange 2 connected to the rear flange 1. The rear flange 1 serves as the drive end of the entire rotating basket, receiving and transmitting the torque of the motor to the entire rotating basket structure. A first roller group 7 and a second roller group 8 are provided between the rear flange 1 and the front flange 2. The first roller group 7 and the second roller group 8 form a low-friction guide rail, ensuring that the washing basket can be easily and accurately pushed into or pulled out of the rotating basket. At least one guide rod is provided on the upper outer side of the first roller group 7 and the second roller group 8, including a first guide rod 11, a second guide rod 12, a third guide rod 13, and a fourth guide rod 14; the first guide rod 11, the second guide rod 12, the third guide rod 13, and the fourth guide rod 14 provide lateral guidance and support for the washing basket. The first guide rod 11 and the third guide rod 13 are located above the outer side of the first roller group 7. One end of the first guide rod 11 and the third guide rod 13 are connected to the rear flange 1, and the other end is connected to the front flange 2 through the first transition flange 3. The outer side of the first transition flange 3 is arc-shaped, and the inner side is provided with arc-shaped holes for connecting to the first guide rod 11 and the third guide rod 13. One end of the first guide rod 11 and the third guide rod 13 passes through the corresponding arc-shaped holes and is welded to the first transition flange 3. The bottom inner side of the first transition flange 3 is connected to the first roller plate 71. The second guide rod 12 and the fourth guide rod 14 are located above the outer side of the second roller group 8. One end of the second guide rod 12 and the fourth guide rod 14 are connected to the rear flange 1, and the other end is connected to the front flange 2 through the second transition flange 4. The second transition flange 4 has the same structure as the first transition flange 3 and is arranged in a mirror image. The inner side of the second transition flange 4 is provided with arc-shaped holes for connecting to the second guide rod 12 and the fourth guide rod 14. One end of the second guide rod 12 and the fourth guide rod 14 passes through the corresponding arc-shaped holes and is welded to the second transition flange 4. The bottom inner side of the second transition flange 4 is connected to the second roller plate 81. The side of the first transition flange 3 closest to the front flange 2 is connected to the front flange 2 through three arc-shaped array of first connecting columns 31. The first connecting columns 31 pass through the reserved through holes on the front flange 2 and are welded to the front flange 2. The side of the second transition flange 4 closest to the front flange 2 is connected to the front flange 2 through three arc-shaped array of second connecting columns 41. The second connecting columns 41 pass through the reserved through holes on the front flange 2 and are welded to the front flange 2.

[0019] The first roller assembly 7 includes a first roller plate 71 and multiple first rollers 72 rotatably connected to the first roller plate 71. The first roller plate 71 is connected to a first transition flange 3 and a rear flange 1 at both ends. The second roller assembly 8 includes a second roller plate 81 and multiple second rollers 82 rotatably connected to the second roller plate 81. The second roller plate 81 is connected to a second transition flange 4 and a rear flange 1 at both ends. The rolling surfaces of the first rollers 72 and the second rollers 82 together form a track for conveying the washing basket into the rotating basket. A first limiting rod 15 and a second limiting rod 16 are also fixed on the rear flange 1 to limit the top of the washing basket as it enters the rotating basket. The other ends of the first limiting rods 15 and 16 are connected to the front flange 2 via a support rod 5, which is connected to the front flange 2 via a third connecting column 51. The first limiting rods 15 and 16 are set at the same height, and the bottom of the first limiting rods 15 and 16 is the highest working level of the cleaning fluid.

[0020] like Figure 2-5 As shown, a rotating basket lifting assembly 6 is provided on the front flange 2, and the rotating basket lifting assembly 6 is located on top of the front flange 2. The rotating basket lifting assembly 6, located on top of the front flange 2, changes the position of the original end bearing. The rotating basket lifting assembly 6 rotatably suspends the entire rotating basket within the cleaning equipment cavity, and the bottom of the rotating basket lifting assembly 6 is above the liquid level plane a of the rotating basket. The rotating basket lifting assembly 6 includes a first fixing plate 61 and a second fixing plate 62. The first fixing plate 61 is fixedly connected to the cleaning equipment cavity. The tops of the first fixing plate 61 and the second fixing plate 62 are connected by multiple fourth connecting posts 63, such as... Figure 3 As shown in the top-down view, there are three fourth connecting columns 63. The first fixing plate 61 and the second fixing plate 62 of the rotating basket hoisting assembly 6 are fixed to each other in parallel intervals by the three fourth connecting columns 63, which are arranged in an arc shape. The bottom of the first fixing plate 61 is connected to the front flange 2 through multiple bearings; the front flange 2 is positioned between the rotating side of the multiple bearings and the multiple fourth connecting columns 63 and rotates relative to the first fixing plate 61 through the multiple bearings. The multiple bearings on the first fixing plate 61 include a first bearing 64, a second bearing 65, and a third bearing 66. The first bearing 64, the second bearing 65, and the third bearing 66 are arranged in an arc shape, and the fixed side of the first bearing 64, the second bearing 65, and the third bearing 66 is connected to the first fixing plate 61, while the rotating side abuts against the front flange 2. Figure 5 As shown, after the rotating basket is installed on the cleaning equipment, the bottom of the lowest bearing is higher than the highest working level a of the cleaning fluid.

[0021] The rear flange 1 is provided with a motor mounting hole 17, and the rotary motor 18 is mounted on the rear flange 1 through the motor mounting hole 17. One end of the first guide rod 11, the second guide rod 12, the third guide rod 13, and the fourth guide rod 14 are welded to the rear flange 1, and the other end is engaged with the arc-shaped hole of the transition flange and then welded. The first fixing plate 61 and the second fixing plate 62 of the rotating basket hoisting assembly 6 constitute the fixed part, and the first bearing 64, the second bearing 65, and the third bearing 66 constitute the rotating part. The fixed part is fixedly connected to the cavity of the cleaning equipment. The rotating part drives the front flange 2 to rotate. The rotary motor 18 can drive the front flange 2 to rotate relative to the fixed part of the rotating basket hoisting assembly 6 through the rear flange 1 and the first guide rod 11, the second guide rod 12, the third guide rod 13, and the fourth guide rod 14.

[0022] In use, the rotating basket is suspended inside the cleaning equipment cavity via the rotating basket lifting assembly 6. First, the first fixing plate 61 of the rotating basket lifting assembly 6 is welded or bolted to the cleaning equipment cavity to ensure stable suspension of the entire rotating basket. The first bearing 64, second bearing 65, and third bearing 66 of the rotating basket lifting assembly 6 support the front flange 2, allowing the front flange 2 to rotate relative to the first fixing plate 61. When the rotary motor 18 is installed and started through the motor mounting hole 17 of the rear flange 1, the motor torque drives the entire rotating basket to rotate through the rear flange 1, causing the front flange 2 to rotate relative to the first fixing plate 61 of the rotating basket lifting assembly 6. The washing basket is pushed into or pulled out of the rotating basket via the track formed by the first roller group 7 and the second roller group 8. The first guide rod 11, second guide rod 12, third guide rod 13, and fourth guide rod 14 provide lateral guidance and support for the washing basket, preventing it from shifting during rotation. The first limiting rod 15 and the second limiting rod 16, together with the support rod 5, axially constrain the washing basket, ensuring that the washing basket will not come out during the cleaning process. Since the rotating basket hoisting assembly 6 and its bearings are located above the highest working level a of the cleaning fluid, the bearings are completely isolated from the cleaning fluid environment, avoiding chemical corrosion and wear, thereby extending the service life of the bearings.

[0023] The improved structure uses a rotating basket lifting assembly 6 instead of the end bearings. The fixed part of the rotating basket lifting assembly 6 is welded to the inside of the cleaning chamber, and the rotating basket rotates during operation using the rotating basket lifting assembly 6. The rotating basket lifting assembly 6 is connected to the front flange 2 via a first bearing 64, a second bearing 65, and a third bearing 66 arranged in an arc shape. The front flange 2 can rotate relative to the first fixed plate 61 along with the first bearing 64, the second bearing 65, and the third bearing 66. The first roller group 7 and the second roller group 8 are responsible for conveying the washing basket into the rotating basket. This allows the rotating bearing position to be raised to a safe area above the highest liquid level a of the cleaning fluid, avoiding the risk of the bearing being soaked in corrosive cleaning fluid. Therefore, this utility model effectively solves the problems of short bearing life and frequent maintenance in the prior art, and improves the service life of the bearing.
