Description

Technical Field

[0001] This utility model relates to the field of decontamination machines, and in particular to a mesh screen decontamination machine. Background Technology

[0002] With the acceleration of urbanization, sewage treatment is becoming increasingly important in urban construction. Bar screens are mechanical devices that remove the screenings trapped by screens from the water surface. Bar screens are used in the pre-treatment stages of sewage treatment to intercept and remove various solid particles and floating debris, ensuring the smooth progress of subsequent processes. They are key equipment for screening and removing debris in the treatment of municipal and industrial wastewater.

[0003] Most current wastewater treatment machines use rotary bar screens. The rotary bar screen rotates continuously, and the rake teeth trap suspended solids in the wastewater. When the trapped material is transported to the top of the equipment, the rake teeth change their direction of movement, and the solid debris falls off by itself.

[0004] The debris on the rotary screens mentioned above often doesn't fall off completely, resulting in low cleaning efficiency. When a large amount of debris remains, it easily clogs the rotary screen. Especially when treating wastewater containing large amounts of fiber and hair, these impurities easily become entangled on the rake teeth, making them difficult to remove using existing self-cleaning and sweeping methods, thus increasing the workload and frequency of maintenance and cleaning. After prolonged use, the rake teeth wear down, requiring repair and replacement, a very time-consuming process. Utility Model Content

[0005] To improve the cleaning effect on materials such as fibers and hair, and to facilitate the maintenance of the cleaning machine, this application provides a mesh screen cleaning machine.

[0006] The technical solution of the mesh bar screen cleaning machine provided in this application is as follows:

[0007] A mesh screen cleaning machine includes a frame, a fixed plate, a mesh screen, and a rotary cleaning assembly. The frame is inclined, and the fixed plate and the mesh screen are both installed on the frame along the inclined direction of the frame. The mesh screen is attached to the fixed plate and located below the fixed plate. The mesh screen is used to allow sewage to pass through and intercept impurities in the sewage.

[0008] The rotary cleaning assembly includes a drive assembly, a conveyor belt, and several brushes. The conveyor belt and several brushes are located above the fixed plate and the grid mesh. The conveyor belt is connected to the frame. The drive assembly drives the conveyor belt. The several brushes are arranged sequentially on the conveyor belt along the conveying direction. When the brushes pass above the grid mesh, they are used to clean the impurities filtered out by the grid mesh.

[0009] The frame has a drain outlet, and the top of the conveyor belt is located directly above the drain outlet.

[0010] By adopting the above technical solution, through the inclined setting of the frame and the reasonable layout of the bar screen and rotary cleaning component, sewage can pass smoothly through the bar screen, impurities are effectively intercepted, and the rotary cleaning component can clean impurities in a timely manner, ensuring the smooth flow of the bar screen. The conveyor belt sends the brush to the top of the bar screen to clean impurities, and finally the impurities are discharged through the sewage outlet. Throughout the process, the brush can better remove the filtered fibers, hair and other substances. The bar screen is fixed and has no rake teeth or other structures, which facilitates the maintenance of the sewage removal machine.

[0011] Preferably, the grating is detachably connected to the frame and the fixing plate. The bottom of the frame is provided with a base frame. Limiting grooves are respectively opened on the base frame and the fixing plate. The two ends of the grating abut against the groove walls of the two limiting grooves respectively.

[0012] By adopting the above technical solution, the detachable connection method of the grating allows for convenient and quick disassembly and installation when the grating becomes clogged, damaged, or needs cleaning, facilitating maintenance and replacement. The setting of the limiting groove ensures the stability and accuracy of the grating installation.

[0013] Preferably, the base frame, the fixing plate, and the top surface of the grid are located on the same plane.

[0014] By adopting the above technical solution, this setup allows the sewage to flow more smoothly when passing through the bar screen, preventing water flow obstruction or impurity accumulation at the connection points due to height differences. This helps improve the decontamination effect and ensures the smooth progress of the entire decontamination process.

[0015] Preferably, the drive assembly includes a motor and a belt, the motor being mounted on a frame, and the belt being wound around the output shaft of the motor and the rotating shaft of the transmission belt.

[0016] By adopting the above technical solution, the drive assembly consisting of a motor and belt has a simple structure, low cost, and can stably drive the conveyor belt, ensuring that the brushes can continuously clean the bar screen. This drive method is easy to maintain and repair, has high transmission efficiency, and can meet the working requirements of the sludge removal machine.

[0017] Preferably, the conveyor belt is provided with mounting frames fixed in sequence along the transmission direction by bolts, and the brush includes a base and multiple bristles fixed on the base. The base is fixed in the mounting frame by screws.

[0018] By adopting the above technical solution, the installation and disassembly of the brush are made more convenient by fixing the mounting frame with bolts and the brush holder with screws. When the brush is worn or damaged, it can be replaced in time to ensure the cleaning effect. It also facilitates regular maintenance and inspection of the brush.

[0019] Preferably, the mounting frame has a chamfered block on its side wall. The chamfered surface of the chamfered block is located away from the brush side and forms an acute angle with the inclined direction of the frame. The screw passes through the chamfered block and the mounting frame in sequence and is threaded onto the base. The head of the screw abuts against and fits against the chamfered surface of the chamfered block.

[0020] By adopting the above technical solution, when it is necessary to disassemble the brush, since the screw head abuts against and fits against the chamfered surface of the chamfered block, the direction of force applied when the screw is turned from this angle changes compared to the conventional installation method. This change reduces the mutual interference between adjacent brushes, makes it easier for operators to apply force, makes the disassembly process more convenient, and improves the efficiency of maintenance.

[0021] Preferably, a scraper is installed on the frame at the drain outlet, and the scraper is located on the movement path of the brush to scrape off impurities on the brush.

[0022] By adopting the above technical solution, the scraper effectively removes residual impurities from the brush, ensuring the brush's cleanliness and allowing it to function better during the next cleaning of the screen. This further improves the cleaning effect of the decontamination machine, reduces impurity residue, and lowers maintenance frequency.

[0023] The main technical effects of this utility model are reflected in the following aspects:

[0024] 1. This utility model, through the inclined setting of the frame and the reasonable layout of the bar screen and rotary cleaning component, allows sewage to pass smoothly through the bar screen, impurities are effectively intercepted, and the rotary cleaning component can clean impurities in a timely manner, ensuring the smooth flow of the bar screen. The conveyor belt sends the brush to the top of the bar screen to clean impurities, and finally the impurities are discharged through the sewage outlet. Throughout the process, the brush can better remove the filtered fibers, hair and other substances. The bar screen is fixed and has no rake teeth or other structures, which facilitates the maintenance of the sewage removal machine.

[0025] 2. The detachable connection method of the grating of this utility model allows for convenient and quick disassembly and installation when the grating is blocked, damaged, or needs cleaning, facilitating maintenance and replacement. The setting of the limiting groove ensures the stability and accuracy of the grating installation. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0032] This application discloses a mesh screen cleaning machine.

[0033] Reference Figures 1-4 The mesh screen cleaning machine of this embodiment includes a frame 1, a fixing plate 21, a mesh screen 22 and a rotary cleaning assembly 3. The frame 1 is inclined. The fixing plate 21 and the mesh screen 22 are both installed on the frame 1 along the inclined direction of the frame 1. The mesh screen 22 is attached to the fixing plate 21 and is located below the fixing plate 21. The mesh screen 22 is used to allow sewage to pass through and intercept impurities in the sewage.

[0034] Reference Figures 1-4 The rotary cleaning assembly 3 includes a drive assembly, a conveyor belt 31, and several brushes 34. The conveyor belt 31 and the brushes 34 are located above the fixed plate 21 and the grid mesh 22. The conveyor belt 31 is driven to the frame 1, and the drive assembly drives the conveyor belt 31. The brushes 34 are sequentially arranged on the conveyor belt 31 along its transmission direction. When the brushes 34 pass over the grid mesh 22, they are used to clean the impurities filtered out by the grid mesh 22. A drain port 13 is located above the frame 1, and the top of the conveyor belt 31 is located directly above the drain port 13.

[0035] Reference Figures 1-4Through the inclined setting of the frame 1 and the reasonable layout of the bar screen 22 and the rotary cleaning component 3, sewage can pass smoothly through the bar screen 22, impurities are effectively intercepted, and the rotary cleaning component 3 can clean impurities in time, ensuring the smooth flow of the bar screen 22. The conveyor belt 31 sends the brush 34 to the top of the bar screen 22 to clean impurities, and finally the impurities are discharged through the sewage outlet 13. Throughout the process, the brush 34 can better remove the filtered fibers, hair and other substances. The bar screen 22 is fixed and has no rake teeth or other structures, which facilitates the maintenance of the sewage removal machine.

[0036] Reference Figures 1-4 The bar screen 22 is detachably connected to the frame 1 and the fixing plate 21. The bottom of the frame 1 is provided with a base frame 23. Limiting grooves 24 are respectively opened on the base frame 23 and the fixing plate 21. The two ends of the bar screen 22 abut against the groove walls of the two limiting grooves 24 respectively.

[0037] Reference Figures 1-4 The detachable connection of the grating 22 allows for easy and quick disassembly and installation when the grating 22 becomes clogged, damaged, or needs cleaning, facilitating maintenance and replacement. The setting of the limiting groove 24 ensures the stability and accuracy of the installation of the grating 22.

[0038] Reference Figures 1-4 The base frame 23, the fixing plate 21 and the top surface of the grid grating 22 are located on the same plane.

[0039] Reference Figures 1-4 This design allows the wastewater to flow more smoothly through the screen 22, preventing water flow obstruction or impurity accumulation at the connection points due to height differences. This improves the cleaning effect and ensures the smooth progress of the entire cleaning process.

[0040] Reference Figures 1-4 The drive assembly includes a motor 32 and a belt. The motor 32 is mounted on the frame 1, and the belt is wound around the output shaft of the motor 32 and the shaft 33 of the transmission belt 31.

[0041] Reference Figures 1-4 The drive assembly consisting of motor 32 and belt is simple in structure, low in cost, and can stably drive the conveyor belt 31 to operate, ensuring that brush 34 can continuously clean the bar screen 22. This drive method is easy to maintain and repair, has high transmission efficiency, and can meet the working requirements of the decontamination machine.

[0042] Reference Figures 1-4 The conveyor belt 31 is provided with mounting frames 35 in sequence along the transmission direction by bolts. The brush 34 includes a base 341 and multiple brush bristles 342 fixed on the base 341. The base 341 is fixed in the mounting frame 35 by screws 36.

[0043] Reference Figures 1-4 The installation and removal of the brush 34 are made convenient by fixing the mounting frame 35 with bolts and the base 341 with screws 36. When the brush 34 is worn or damaged, it can be replaced in time to ensure the cleaning effect. It also makes it easy to perform regular maintenance and inspection of the brush 34.

[0044] Reference Figures 1-4 A chamfered block 351 is provided on the side wall of the mounting frame 35. The chamfered surface 352 of the chamfered block 351 is set away from the side of the brush 34 and is set at an acute angle with the tilt direction of the frame 1. The screw 36 passes through the chamfered block 351 and the mounting frame 35 in sequence and is threaded onto the base 341. The head of the screw 36 abuts against and fits against the chamfered surface 352 of the chamfered block 351.

[0045] Reference Figures 1-4 When it is necessary to disassemble the brush 34, since the head of the screw 36 abuts against and fits against the chamfered surface 352 of the chamfered block 351, the direction of force is changed when the screw 36 is turned from this angle compared with the conventional installation method. This change reduces the mutual interference between adjacent brushes 34, makes it easier for operators to apply force, makes the disassembly process more convenient, and improves the efficiency of maintenance.

[0046] Reference Figures 1-4 A scraper 11 is installed on the frame 1 at the drain outlet 13. The scraper 11 is positioned along the movement path of the brush 34 and is used to scrape away impurities from the brush 34. The scraper 11 effectively removes residual impurities from the brush 34, ensuring its cleanliness and allowing it to function better during the next cleaning of the grid screen 22. This further improves the cleaning effect of the cleaning machine, reduces impurity residue, and lowers the maintenance frequency.

[0047] Reference Figures 1-4 The scraper 11 has several comb teeth 12, which can clean the bristles 342 more deeply.

[0048] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
