Description
Technical Field
The invention relates to the technical field of circulating water filtering systems, in particular to a drum filter screen driving device.
Background
The drum filter screen is used as the last-stage large-scale filtering equipment for resisting marine organisms in a nuclear power plant cold source 'depth defense' system, the performance of the drum filter screen directly determines the safety of the cold source of the power plant and the safe and stable operation of a unit, and once the drum filter screen breaks down, the power reduction of the unit and even the shutdown of a reactor can be caused.
The drum type filter screen is generally divided into two forms of 'external inlet and internal outlet' and 'internal inlet and external outlet', and the two forms are different in that when the drum type filter screen operates in an 'internal inlet and external outlet' mode, water enters from the inner side of the drum type filter screen and flows out from the outer side of the drum type filter screen. On the contrary, when the drum-shaped filter screen with the external inlet and the internal outlet operates, water flows into the outer side of the drum-shaped filter screen and flows out from the inner side of the outer side of the drum-shaped filter screen, so that garbage such as marine life and the like can be intercepted on the outer side of the drum-shaped filter screen.
When the drum-shaped filter screen runs, the drum-shaped filter screen is driven by the driving device to rotate, so that the filtering of garbage such as marine organisms in water is realized. The "out in out" type of drum screens operate with a higher outside water level than the inside water level, and therefore, to avoid the impact and damage of debris on the drive, the drive is typically placed above the water level inside the drum screen.
Referring to fig. 1, a conventional drum filter 1 of the "out-in-out" type is driven to rotate by a driving device 2. The main body of the drive device 2 is fixed to the foundation 3. The drive shaft 4 of the drive means 2 is placed in a horizontal direction. The force output of the drive shaft 4 is connected to the drum screen 1, so that the drum screen 1 can be rotated. Wherein, the force output end of the transmission shaft 4 is provided with a pinion 5, and the drum filter screen 1 is provided with a big gear ring 6. Through pinion 5 and bull gear 6 meshing to when transmission shaft 4 drove pinion 5 and rotates, pinion 5 can drive bull gear 6 and rotate, and bull gear 6 then can drive drum filter 1 and rotate. Wherein, the cover is equipped with bearing frame 7 on the transmission shaft 4, and bearing frame 7 is supported by support 8, and the lower extreme of support 8 is fixed in ground 3 to can indirectly support transmission shaft 4 and bearing frame 7. Due to the restriction of the foundation 3 to the support 8, the drive shaft 4 and the bearing housing 7 cannot move downward in the vertical direction. And the pinion 5 is restricted by meshing with the large gear ring 6, so that the transmission shaft 4 and the bearing seat 7 cannot move in a horizontal direction perpendicular to the axial direction of the transmission shaft 4 and cannot move upward. Also due to the small space inside the drum screen 1, the movement of the drive shaft 4 and the bearing housing 7 is further made very difficult, resulting in difficulties in replacing the bearing housing 7 and the bearings inside the bearing housing 7.
In order to facilitate replacement of the bearing seats and the bearings in the bearing seats, the drive device of the drum filter screen generally adopts a split bearing seat. However, since a large amount of water vapor exists inside the drum screen and the water filtered by the drum screen is easily splashed onto the driving device, the sealing performance of the split bearing housing is not good, so that the bearing in the split bearing housing is easily corroded. Therefore, the traditional drum filter screen driving device has the problems that the bearing seat and the bearing are difficult to replace and the bearing is easy to corrode.

Referring to fig. 2, a drive device 100 for a drum screen (hereinafter referred to as the drive device 100) according to an embodiment of the present disclosure includes a support assembly 110, an integral bearing seat 120, a drive shaft 130, and a drive assembly. The first and second directions and the third direction are defined in the present application. The second direction is along an axial direction of the drive shaft 130 and the third direction is along a radial direction of the drive shaft 130. In practical use, the first direction is along the vertical direction, and the second direction and the third direction are respectively along the horizontal direction and are perpendicular to each other. For convenience of description, the vertical direction is used instead of the first direction, and the axial direction of the transmission shaft 130 is used instead of the second direction.
The mount assembly 110 includes a main mount 111 and a transition mount 112. Specifically, in the driving device 100, in practical use, the main support 111, the transition support 112 and the integral bearing seat 120 are sequentially arranged upward along the vertical direction, and the upper end and the lower end of the transition support 112 are detachably connected with the main support 111 and the integral bearing seat 120, respectively. The lower end of the main support 111 is fixed to the foundation so that the main support 111 can support the transition support 112 and the transition support 112 can support the integrated bearing housing 120.
The drive shaft 130 is axially inserted through the integral bearing housing 120. Referring to fig. 3, a bearing 120a is disposed in the integral bearing seat 120, and the transmission shaft 130 is rotatably connected to the integral bearing seat 120 through the bearing 120a, so that the transmission shaft 130 can rotate around its axis with respect to the integral bearing seat 120, and the transmission shaft 130 can be supported by the integral bearing seat 120.
The lower end of the driving assembly is used for being fixed on a foundation. The force output end of the driving assembly is detachably connected with the force input end of the transmission shaft 130, and the driving assembly is used for driving the transmission shaft 130 to rotate around the axis of the driving assembly, so that the transmission shaft 130 can drive the drum filter (not shown) to rotate to perform filtering operation. Wherein, the force output end of the transmission shaft 130 is provided with a pinion 131, a bull gear (not shown) is arranged on the drum filter, and the transmission shaft 130 drives the drum filter to rotate through the meshing of the pinion 131 and the bull gear.
The driving device 100 of the drum filter screen has good sealing performance due to the integral bearing seat 120, thereby reducing or avoiding the risk of corrosion of the bearing 120a inside the integral bearing seat 120 and improving the operation reliability of the bearing 120 a. When it is desired to replace the integral bearing housing 120 and the bearing 120a therein, the force output end of the drive assembly is detached from the force input end of the drive shaft 130 to release the drive assembly from the restriction of movement of the drive shaft 130, and the transition support 112 is detached from the integral bearing housing 120 and the main support 111, respectively, to remove the transition support 112. The removal of the transition support 112 allows for vertical downshifting of the integrated bearing housing 120 and drive shaft 130. When the integrated bearing housing 120 and the transmission shaft 130 are moved downward in the vertical direction, the pinion 131 can be disengaged from the ring gear, so that the pinion 131 can be moved in the third direction, and the integrated bearing housing 120 and the transmission shaft 130 can be moved in the third direction. At this time, the integral bearing seat 120 and the transmission shaft 130 can be flexibly moved along the first direction, the second direction and the third direction, respectively, so that the integral bearing seat 120 and the transmission shaft 130 can be conveniently moved out of the drum filter, and the integral bearing seat 120 and the bearing 120a inside the integral bearing seat 120 can be conveniently replaced. It can be seen that the driving device 100 not only can facilitate the replacement of the integrated bearing housing 120 and the bearing 120a therein, but also the bearing 120a is not easily corroded.
It will be appreciated that the pinion gear 131 has a smaller outer diameter and a larger inner diameter than the bull gear, and when the pinion gear 131 is engaged with the upper inner wall of the bull gear inside the bull gear, the bull gear restricts the pinion gear 131 from moving in the third direction and restricts the pinion gear 131 from moving upward in the vertical direction, as compared to the bull gear. Therefore, the pinion 131 is disengaged from the ring gear when moving downward within the ring gear, and can move in the third direction and the vertical direction within the ring gear, respectively.
Referring to fig. 3, in an embodiment, the driving device 100 further includes a lip seal 121. The lip seal 121 is disposed between the drive shaft 130 and the integrated bearing housing 120 in a radial direction of the drive shaft 130. That is, the lip seal 121 is fitted to the transmission shaft 130, and the integrated bearing housing 120 is fitted to the lip seal 121, so that the sealing performance of the integrated bearing housing 120 can be further improved, and the bearing 120a in the integrated bearing housing 120 can be prevented from being corroded.
Further, along the axial of transmission shaft 130, the both sides of the bearing 120a in the integral bearing frame 120 are provided with lip seal 121 respectively to can effectively improve the leakproofness at integral bearing frame 120 both ends, further guarantee that bearing 120a is difficult for corroding.
Referring to fig. 3, in an embodiment, the outer circumferential surface of the transmission shaft 130 is provided with a drainage groove 101, so that water on the outer surface of the one-piece bearing housing 120 can fall into the drainage groove 101 and flow away through the drainage groove 101, and thus the bearing 120a is not easily corroded. In addition, the drainage groove 101 is located on the side of the lip-shaped sealing ring 121 far away from the bearing 120a along the axial direction of the transmission shaft 130, so that water in the drainage groove 101 is blocked by the lip-shaped sealing ring 121 and cannot enter the bearing 120a, and the bearing 120a is further effectively ensured not to be corroded easily.
As shown in fig. 3, in the present embodiment, the sides of the two lip-shaped sealing rings 121 far away from the bearing 120a are respectively provided with a drainage groove 101, so that water on both sides of the bearing 120a can be conveniently drained from the drainage grooves 101.
Further, as shown in fig. 3, the drainage channel 101 is located outside the integral bearing seat 120 along the axial direction of the transmission shaft 130, so that the drainage channel 101 can be drained outside the integral bearing seat 120, and further, the bearing 120a is not easy to corrode.
Further, as shown in fig. 3, in the present embodiment, the drain groove 101 surrounds the drive shaft 130 in the circumferential direction of the drive shaft 130, thereby facilitating easier drainage of the drain groove 101.
Referring to fig. 1, in one embodiment, a driving assembly includes: a reducer 141 and a driver 142. The drive 142 is, for example, a motor or other drive. The driving member 142 is used for driving the speed reducer 141 to move, and a force output end of the speed reducer 141 is detachably connected with a force input end of the transmission shaft 130, so that the transmission shaft 130 can be driven to rotate around the axis of the transmission shaft.
The force output end of the reducer 141 is detachably connected to the force input end of the propeller shaft 130, and therefore, when the force output end of the reducer 141 is detached from the force input end of the propeller shaft 130, the restriction on the force input end of the propeller shaft 130 can be released.
Referring to fig. 1, in one embodiment, the driving device 100 further comprises a coupling, which comprises a first coupling half 143 and a second coupling half 144 that are detachably connected. The first coupling half 143 is connected directly or indirectly to the force output end of the drive assembly and the second coupling half 144 is connected to the force input end of the drive shaft 130.
Specifically, in this embodiment, the first coupling half 143 is connected to a force output end of the speed reducer 141, and the second coupling half 144 is connected to a force input end of the transmission shaft 130, so that when the first coupling half 143 is connected to the second coupling half 144, the speed reducer 141 can drive the transmission shaft 130 to rotate. When the first coupling half 143 and the second coupling half 144 are removed, the restriction of the reduction gear 141 on the force input end of the transmission shaft 130 can be released.
In other embodiments, the driving assembly may not include a speed reducer, and the force output end of the driving member is directly detachably connected to the force input end of the transmission shaft, rather than being indirectly connected to the force input end of the transmission shaft through the speed reducer.
Referring to fig. 2, in an embodiment, the driving apparatus 100 further includes a transportation apparatus 150, and the transportation apparatus 150 includes: a support part 151 and a moving part 152.
Specifically, in actual use, the supporting portion 151 is disposed above the moving portion 152 for supporting the object to be transported. The moving part 152 is connected to the supporting part 151, and the moving part 152 can move in a horizontal direction to move the supporting part 151. The bottom of the moving part 152 can be conveniently moved by providing casters.
When the driving shaft 130 and the integral bearing housing 120 are moved to the outside of the drum screen, the driving shaft 130 and the integral bearing housing 120 may be supported in a vertical direction by the supporting portion 151, and the moving portion 152 drives the supporting portion 151 to move in a horizontal direction, thereby conveniently moving the driving shaft 130 and the integral bearing housing 120 to the outside of the drum screen.
In an embodiment, the supporting portion 151 is adjustable in position relative to the moving portion 152 in a vertical direction.
Specifically, referring to fig. 2, in the present embodiment, the transportation device 150 further includes a telescopic mechanism 153 capable of extending and retracting along a vertical direction. The telescopic mechanism 153 is located between the support portion 151 and the moving portion 152, and is connected to the support portion 151 and the moving portion 152, respectively. The telescopic mechanism 153 is, for example, a hydraulic support rod, an air cylinder, or the like.
Before the transition support 112 is not disassembled, the telescoping mechanism 153 may be shortened, so that the height of the support part 151 can be lowered, and the support part 151 can be lower than the transmission shaft 130 and the integrated bearing seat 120 by a certain distance. The transport device 150 is then moved under the drive shaft 130. So, dismantle the back with transition support 112, when transmission shaft 130 and integral bearing frame 120 moved down, then can directly fall on supporting part 151 to conveniently shift transmission shaft 130 and integral bearing frame 120 to conveyer 150, need not to utilize the manpower specially to lift transmission shaft 130 and integral bearing frame 120 to on the supporting part 151.

After the drive assembly is leveled, the drive assembly can be fixed with the foundation. The first leveling mechanism 171 is, for example, a leveling bolt.
Referring to fig. 2 and fig. 5, in an embodiment, the driving apparatus 100 further includes: a plurality of second leveling mechanisms 172. The second leveling mechanism 172 is connected to the lower end of the main support 111 and is used for adjusting the position of the main support 111 along the vertical direction, so that the positions of the transition support 112, the integral bearing seat 120 and the transmission shaft 130 along the vertical direction can be adjusted, and the transmission shaft 130 can be leveled when the transmission shaft 130 is installed, so that the installation accuracy of the transmission shaft 130 is improved.
