Description

Technical Field

[0001] This utility model belongs to the technical field of bar screen cleaning devices, and in particular relates to a bar screen cleaning device for water supply and drainage engineering. Background Technology

[0002] A bar screen is a type of cleaning machine that separates solids from liquids using a bar screen. The most commonly used type is the rotary bar screen, which does not have a stationary bar screen. Instead, it uses a dense array of rakes that move with a rotary traction chain to remove dirt from the water.

[0003] The installation angle of a bar screen is typically 60-85 degrees, depending on the sewage flow rate and the amount of solid particles to be removed. For example, when the flow rate is high, the installation angle is generally smaller to improve its resistance to water pressure. However, once the bar screen is installed, its installation angle is fixed and cannot be changed. When the sewage flow rate or its solid content changes, the angle cannot be adjusted according to the requirements. Therefore, it is necessary to design a bar screen for water supply and drainage engineering to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a bar screen cleaning device for water supply and drainage engineering, which has the advantage of adjustable installation angle, so as to solve the above-mentioned technical problems.

[0017] Figure 1-4 This invention illustrates a screen cleaning device for water supply and drainage engineering according to an embodiment of the present invention, which includes: The main body of the rotary bar screen cleaning device is installed inside the sewage well 1. Specifically, the main body of the rotary bar screen cleaning device includes a frame 21 installed inside the sewage well 1. A traction chain 23 is installed inside the frame 21 via two upper and lower mounting shafts 22. A toothed rake 24 that works with the bar screen 3 is installed on the surface of the traction chain 23. The main body of the rotary bar screen cleaning device is rotatably connected to the inside of the sewage well 1 via an angle adjustment component. Specifically, the angle adjustment component includes two fixing blocks 71 fixed inside the sewage well 1. The bottom of the frame 21 is rotatably connected between the two fixing blocks 71 via a rotating shaft 72. The left and right sides of the frame 21 are also connected. Each component is equipped with a fixed mounting plate 74, which is fixedly installed on the surface of the sewage well 1. Rotating rods 73 are rotatably connected to both sides of the frame 21. Threaded sleeves 76 are rotatably connected to the bottom of the rotating rods 73, and slide on the top of the fixed mounting plate 74. Specifically, a threaded rod 75 is rotatably connected to the top of the fixed mounting plate 74, and the threaded sleeve 76 is threaded onto the surface of the threaded rod 75. A hexagonal hole is provided on the rear side of the threaded rod 75. Furthermore, mounting ears 77 are bolted to both sides of the frame 21 and are fixedly installed on the top of the fixed mounting plate 74. The top of the 74 has multiple mounting holes 78, and the surface of the frame 21 has multiple mounting holes 79. With the mounting ears 77 installed, after the installation angle of the rotary bar screen is determined, the mounting ears 77 can be connected to the fixed mounting plate 74, improving the stability of the rotary bar screen during use. A bar screen 3 is fixedly installed at the bottom front of the rotary bar screen. A flexible bar screen base plate assembly 4 is installed at the bottom of the bar screen 3. The end of the flexible bar screen base plate assembly 4 away from the bar screen 3 is fixedly installed at the bottom of the inner cavity of the sewage well 1. Specifically, the flexible bar screen base plate assembly... Component 4 includes a grid strip 41 rotatably connected to the bottom of the grid baffle 3. There are multiple grid strips 41, and two adjacent grid strips 41 are rotatably connected. The bottom of the bottommost grid strip 41 is rotatably connected to an installation rod 42. The installation rod 42 is fixedly installed at the bottom of the inner cavity of the sewage well 1. With the setting of the flexible grid bottom plate assembly 4, when the installation angle of the main body of the rotary grid cleaning device changes, the grid strips 41 in the flexible grid bottom plate assembly 4 will rotate, so as to always intercept impurities in the inner cavity of the sewage well 1 and avoid impurities passing through the inner cavity at the bottom of the grid baffle 3 during the angle adjustment process, which would affect the cleaning effect. The rotary bar screen cleaning device has a cleaning component inside its main body. Specifically, the cleaning component includes a mounting cylinder 61 rotatably connected to the top of the inner cavity of the frame 21. The surface of the mounting cylinder 61 is equipped with cleaning bristles 62 that work with the rake 24. With the cleaning component, the cleaning bristles 62 can clean the rake 24 while it is being transported and dumping impurities by the traction chain 23, thus preventing incomplete removal of impurities from the rake 24 and affecting the overall cleaning effect. Specifically, a drive transmission device 25 is fixedly installed on the top of the frame 21. The right side of the top mounting shaft 22 extends to the outside of the frame 21 and is connected to the output shaft of the drive transmission device 25 via a belt pulley.

The top of the sewage well 1 is equipped with a receiving trolley 5 that works in conjunction with the main body of the rotary bar screen cleaning device.

[0018] Working principle: When using this utility model, the user inserts a special tool into the inner cavity of the threaded rod 75 and rotates the threaded rod 75, thereby causing the threaded sleeve 76 to slide on the surface of the fixed mounting plate 74, thereby causing the rotating rod 73 to rotate and support the frame 21. Then, the frame 21 rotates in the inner cavity of the sewage well 1 about the rotating shaft 72 as the axis, thereby adjusting the installation angle of the frame 21 to meet different needs. Subsequently, the mounting ears 77 are fixedly installed according to the actual position of the frame 21 and fixedly installed on the top of the fixed mounting plate 74 to strengthen the support of the frame 21. When sewage passes through the inner cavity of the sewage well 1, the bar screen 3 and the flexible bar bottom plate assembly 4 will filter the sewage in the sewage well 1, and the toothed rake 24 in the main body of the rotary bar cleaning device will clean the impurities intercepted on the surface of the flexible bar bottom plate assembly 4 and transport them to the inner cavity of the receiving trolley 5 for collection.

[0019] In summary, the bar screen cleaning device used in this water supply and drainage project filters sewage in the sewage well 1 through the bar screen 3 and the flexible bar screen base plate assembly 4, and cleans impurities on the surface of the bar screen 3 through the main body of the rotary bar screen cleaning device and conveys them to the inner cavity of the receiving trolley 5. With the help of the angle adjustment component, the installation angle of the main body of the rotary bar screen cleaning device can be flexibly adjusted according to the needs, thereby improving its practicality.
