Technical Field

[0001] This utility model relates to a rotary filter device, belonging to the field of filter equipment. Background Technology

[0002] Rotary filters are highly automated and can operate continuously without human intervention. They are typically installed at the inlet of water supply and drainage projects such as pumping stations and hydropower stations.

[0003] like Figure 3 As shown, existing rotary filters intercept floating debris such as branches, leaves, weeds, garbage, and ice floes carried by the water flow. A geared motor drives a screen fixed to a chain to scoop the debris to the vicinity of the top flushing water system. The flushing water system then washes the debris into a collection tank, reducing head loss in the inlet channel and improving unit operating efficiency. However, the following shortcomings still exist:

[0004] 1. The equipment has high manufacturing costs, occupies a large area, and requires a large space on the construction site;

[0005] 2. The screen plate and chain rotate back and forth around the main shaft, and the water has to pass through the screen plate twice, which can easily create high water pressure and make maintenance inconvenient;

[0006] 3. The use of a large number of transmission sprockets requires high precision in the assembly of large and small transmission sprockets. It is difficult to guarantee the center alignment of the chain teeth of large and small transmission sprockets, which can easily lead to instability in the operation of the system.

[0007] Therefore, there is a need for a rotary disc filtration device that reduces the footprint, facilitates maintenance, and improves operational stability. Summary of the Invention

[0008] The technical problem to be solved by this utility model is: to overcome the shortcomings of the existing technology and provide a rotary filter device that reduces the footprint, facilitates maintenance, and improves operational stability.

[0013] Preferably, the drive motor is a geared motor.

[0014] Preferably, the frame is provided with two second tracks, which are arranged side by side and vertically, and the cleaning belt passes through the two second tracks in sequence.

[0015] Preferably, the frame is also provided with a second flushing system, which is located below the cleaning belt.

[0016] Preferably, the mesh plate includes a mounting ring with its axis arranged horizontally. One side of the mounting ring has an opening. In two adjacent mounting rings, the side of one mounting ring away from the opening is fitted with the sidewall of the opening of the other mounting ring.

[0017] Preferably, a comb-tooth rake is fixedly provided on the inner peripheral wall of the mounting ring.

[0018] Preferably, a retaining pad is laid on the inner peripheral wall of the mounting ring.

[0019] Preferably, the opening is arc-shaped.

[0032] like Figure 1-2 As shown, a rotary filter device in this embodiment includes a frame 1, on which a first flushing system 2, a drive system 3 and a cleaning belt 4 are provided. The cleaning belt 4 is a vertical ring structure. The drive system 3 is used to drive each screen plate 41 to perform a continuous planar rotation. The direction of the rotation is matched with the ring structure. The first flushing system 2 is used to flush the dirt on the screen plate 41.

[0033] The cleaning belt 4 includes multiple mesh plates 41, which are connected end to end to form a vertical ring structure. Each mesh plate 41 is connected to the drive system 3.

[0034] During operation, frame 1 is fixed to the civil engineering structure. Some mesh panels 41 are located within the water flow that needs cleaning, while other mesh panels 41 are located above the water flow. The first flushing system 2 is located above the water flow. The drive system 3 causes each mesh panel 41 to perform a continuous planar rotation. The specific actions are as follows:

[0035] The screen plate 41 located in the water flow traps the dirt in the water flow. As the screen plate 41 rises, it carries the dirt to the top of the water flow. When the screen plate 41 carries the dirt to the first flushing system 2, the first flushing system 2 applies clean water to the screen plate 41, causing the dirt trapped on the screen plate 41 to be flushed away. Subsequently, as the screen plate 41 continues to move, it turns and moves downward. When the screen plate 41 moves downward into the water flow and continues to trap dirt, it turns and moves upward again, and so on.

[0036] In addition, when the first flushing system 2 flushes the dirt off the mesh plate 41, a dirt collection system can be installed on the frame 1 to collect the flushed dirt. The dirt collection system can be a dirt collection tank or a screw conveyor.

[0037] The first flushing system 2 can be a spray pipe and a water pump. The spray pipe is connected to the water pump, and the water pump is connected to the water storage unit. When the water pump starts, it delivers clean water from the water storage unit to the spray pipe, and then the spray pipe discharges the water and acts on the mesh plate 41.

[0038] The drive system 3 includes a chain 31 and two sprockets 32 connected by the chain 31. The two sprockets 32 are distributed vertically, with the upper sprocket 32 ​​driven by a drive motor 33. The mesh plate 41 is fixedly mounted on the chain 31. The drive motor 33 is a geared motor. Here, the upper sprocket 32 ​​is located above the water flow, and the lower sprocket 32 ​​is located inside the water flow. When the drive motor 33 starts, it causes the upper sprocket 32 ​​to rotate, and drives the lower sprocket 32 ​​to rotate synchronously through the chain 31. During this time, the chain 31 performs a continuous planar rotation, thus driving the mesh plate 41 to perform a continuous planar rotation. The optimal adaptation of flow rate and cleaning efficiency ratio can be achieved by the variable speed of the drive motor 33.

[0039] The frame 1 is provided with two first tracks 5, which are arranged side by side and vertically. The chain 31 passes through the two first tracks 5. During operation, when the chain 31 drives the mesh plate 41 to rise, the chain 31 passes through one of the first tracks 5. When the chain 31 drives the mesh plate 41 to fall, the chain 31 passes through the other first track 5. Through the cooperation between the chain 31 and the first track 5, the chain 31 is guided when it moves.

[0040] The frame 1 is provided with two second tracks 6, which are arranged side by side and vertically. The cleaning belt 4 passes through the two second tracks 6 in sequence. During operation, when the mesh plate 41 rises, it passes through one of the second tracks 6, and when the mesh plate 41 falls, it passes through the other second track 6. The cooperation between the mesh plate 41 and the second track 6 guides the movement of the cleaning belt 4.

[0041] The frame 1 is also provided with a second flushing system 7, which is located below the cleaning belt 4. The second flushing system 7 can have the same structure as the first flushing system 2. In fact, the second flushing system 7 is located in the water flow. During the cleaning of the cleaning belt 4, clean water is applied to the mesh plate 41 through the second flushing system 7 to facilitate rinsing the base of the bottom of the mesh plate 41.

[0042] The mesh plate 41 includes a mounting ring 411 with its axis arranged horizontally. One side of the mounting ring 411 has an opening 412, which is arc-shaped. In two adjacent mounting rings 411, the side of one mounting ring 411 away from the opening 412 is fitted against the sidewall of the opening 412 of the other mounting ring 411. A filter screen 413 is fixedly mounted at one end of the mounting ring 411. A comb-tooth rake 414 is fixedly mounted on the inner peripheral wall of the mounting ring 411. A retaining pad 415 is laid on the inner peripheral wall of the mounting ring 411. During operation... During this process, water flows through the mounting ring 411 from the end of the mounting ring 411 away from the filter screen 413, and the filter screen 413 intercepts the dirt in the water. When there is large dirt in the water, the toothed rake 414 can scoop the dirt into the mounting ring 411 and intercept it through the filter screen 413, or the dirt can be suspended on the toothed rake 414. In addition, when the screen plate 41 rises, the opening 412 faces upward, and conversely, when the screen plate 41 falls, the opening 412 faces downward. During the rotation of the screen plate 41, the mounting ring 411 rotates in the opening 412 and always fits against the inner wall of the opening 412.

[0043] In summary, this rotary filter has a compact structure and occupies little space; compared with existing technologies, it does not generate large water pressure, and the screen plate 41 can be replaced on the ground without the need for channel drainage. The rotating chain 31 in the track is maintenance-free under normal circumstances, and is easy to disassemble and maintain. The transmission is simple, and the force of the water flow applied to the screen plate 41 is transmitted to the civil engineering, resulting in high operational stability.

[0044] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
