Description

Technical Field

[0001] This application relates to the field of bar screen cleaning technology, and in particular to a device for synchronous cleaning of bar screen debris. Background Technology

[0002] In water treatment systems, bar screens, as a primary pretreatment device, are widely used in various wastewater treatment scenarios. The function of a bar screen is to intercept larger suspended solids and floating debris, such as leaves, plastic bags, and other solid waste, preventing these objects from entering subsequent treatment stages. This protects pumps, pipes, and other equipment from clogging, ensuring the normal operation of the wastewater treatment equipment. Bar screens are typically installed in the initial stage of wastewater treatment to improve overall wastewater treatment efficiency.

[0003] The working principle of a bar screen is mainly that a set of parallel metal bars form a bar screen. When sewage flows through the bar screen, larger solid impurities are intercepted in front of the bars, while the sewage continues to flow to the subsequent treatment stage.

[0004] However, during the actual operation of the screen, intercepted garbage and debris inevitably fall into the gaps of the screen mesh, causing cleaning difficulties. These fallen debris gradually accumulate in the gaps, forming blockages, hindering sewage flow, and reducing the effective water passage area of ​​the screen. If not cleaned for a long time, the accumulated debris will affect the sewage flow rate and may even cause sewage backflow. Therefore, it is urgent to clean the screen debris that clogs the screen during operation to reduce the impact on the normal operation of the screen. Utility Model Content

[0005] To reduce the possibility of grid clogging during operation, this application provides a grid clogging synchronous cleaning device.

[0006] This application provides a synchronous cleaning device for bar screen debris, which adopts the following technical solution:

[0007] A screen cleaning device is provided below the screen mesh of a bar screen. It includes a roller brush, a rotating shaft, and a driving component. One end of the rotating shaft is coaxially fixed to the roller brush, and the other end is coaxially fixed to the output end of the driving component. The roller brush is provided with bristles for cleaning the debris clogging the screen mesh. The roller brush is also provided with a rinsing mechanism for intermittently rinsing the bristles. The rinsing mechanism is drivenly connected to the rotating shaft.

[0008] By adopting the above technical solution, the drive component can rotate the roller brush via the rotating shaft, enabling the bristles on the roller brush to clean the screenings clogging the grid. After a period of time, the roller brush can automatically drive the flushing and suction mechanism to rinse the screenings adhering to the bristles, allowing the bristles to penetrate into the gaps of the grid in a relatively clean state. This reduces the risk of the bristles carrying the brushed-off screenings back into the gaps of the grid during the cleaning process, thus preventing secondary clogging.

[0009] Optionally, the rinsing mechanism includes a cleaning component for cleaning the bristles and a power component for driving the cleaning component to perform intermittent automatic cleaning.

[0010] By adopting the above technical solution, the rinsing component can clean the slag adhering to the bristles, while the power component can transmit the power of the rotating shaft to the rinsing component, enabling the rinsing component to automatically perform intermittent cleaning of the bristles.

[0011] Optionally, the cleaning assembly includes a cleaning chamber and cleaning nozzles. The cleaning chamber is disposed between the roller brush and the bristles. The cleaning chamber is filled with clean water for rinsing the bristles. Multiple cleaning nozzles are provided and all communicate with the inner cavity of the cleaning chamber.

[0012] The power unit is connected to the cleaning chamber and is used to drive the clean water in the cleaning chamber to be sprayed out intermittently from each of the cleaning nozzles.

[0013] By adopting the above technical solution, when the power component is activated, the pressure inside the cleaning chamber can be increased, thereby causing clean water inside the cleaning chamber to be sprayed out from each cleaning nozzle, thus completing the rinsing and cleaning of the grid residue adhering to the brush bristles.

[0014] Optionally, each of the cleaning nozzles is provided with a first one-way valve for controlling the one-way outflow of clean water.

[0015] By adopting the above technical solution, the first one-way valve can prevent the debris on the brush bristles from entering the cleaning nozzle, thereby protecting the cleaning nozzle and reducing the possibility of clogging.

[0016] Optionally, the cleaning nozzles are spaced apart and evenly distributed on the outer wall of the cleaning chamber.

[0017] By adopting the above technical solution, the evenly arranged cleaning nozzles can rinse the brush bristles evenly, thereby uniformly removing the slag adhering to the brush bristles.

[0018] Optionally, the power assembly includes an annular piston plate, a connecting cylinder, a plug rod, and a bidirectional threaded rod. The annular piston plate is sealed to the inner cavity of the cleaning chamber. One end of the connecting cylinder is fixedly connected to the annular piston plate. The plug rod is fixed to the inner wall of the connecting cylinder. The bidirectional threaded rod is coaxially fixed to the rotating shaft, and the end of the plug rod away from the connecting cylinder is slidably inserted into the bidirectional thread of the bidirectional threaded rod.

[0019] A water injection assembly for automatically adding clean water to the cleaning chamber is provided between the cleaning chamber and the annular piston plate.

[0020] By adopting the above technical solution, when the driving component drives the rotating shaft to rotate, the rotating shaft drives the bidirectional threaded rod to rotate, thereby causing the insert rod to move the connecting cylinder, and the connecting cylinder to move the annular piston plate, thereby changing the air pressure in the cleaning chamber. When the air pressure in the cleaning chamber increases, the water injection component injects water into the cleaning chamber, and at this time, the clean water in the cleaning chamber is sprayed out by each cleaning nozzle. When the air pressure in the cleaning chamber decreases, the water injection component adds external water to the water injection component, so that there is always clean water that can be added to the cleaning chamber.

[0021] Optionally, the water injection assembly includes a water storage tank and a water inlet pipe. One end of the water storage tank is rotatably and sealed to the cleaning tank, and the annular piston plate is slidably and sealed to the other end of the water storage tank. One end of the water inlet pipe is connected to the inner cavity of the water storage tank, and the other end is connected to an external water source. A second one-way valve is provided inside the water inlet pipe to control the one-way entry of the external water source into the water storage tank.

[0022] By adopting the above technical solution, when the annular piston plate moves towards the cleaning chamber, the clean water in the water storage tank enters the cleaning chamber. When the annular piston plate moves away from the cleaning chamber, the external water source enters the water storage tank through the second one-way valve, thereby replenishing the clean water in the water storage tank.

[0023] Optionally, a third one-way valve is provided on the water outlet end of the water storage tank that extends into the cleaning tank. The third one-way valve can control the clean water in the water storage tank to enter the cleaning tank in one direction.

[0024] By adopting the above technical solution, the third one-way valve can prevent water entering the cleaning chamber from flowing back into the water storage chamber, ensuring that the water inlet pipe can be intermittently replenished with clean water.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The drive unit can drive the roller brush to rotate through the rotating shaft, so that the bristles on the roller brush can clean the screen residue clogging the screen. After a period of time, the roller brush can automatically drive the flushing and suction mechanism to rinse the screen residue adhering to the bristles, so that the bristles can enter the gaps of the screen in a relatively clean state, reducing the possibility of the bristles bringing the brushed-off screen residue back into the gaps of the screen during the cleaning process, causing secondary blockage of the screen residue.

[0027] 2. The first check valve can prevent debris on the brush bristles from entering the cleaning nozzle, thereby protecting the cleaning nozzle and reducing the possibility of clogging.

[0028] 3. The evenly spaced cleaning nozzles can rinse the brush bristles evenly, thereby uniformly removing the debris adhering to the bristles.

[0029] 4. When the drive unit drives the rotating shaft to rotate, the rotating shaft drives the bidirectional threaded rod to rotate, thereby causing the insert rod to move the connecting cylinder, and the connecting cylinder to move the annular piston plate, thereby changing the air pressure in the cleaning chamber. When the air pressure in the cleaning chamber increases, the water injection component injects water into the cleaning chamber, and at this time, the clean water in the cleaning chamber is sprayed out from each cleaning nozzle. When the air pressure in the cleaning chamber decreases, the water injection component adds external water to the water injection component, so that there is always clean water that can be added to the cleaning chamber.
