Description

An automatic cleaning bar screen device Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic cleaning bar screen device. Background Technology

[0002] There are many methods for treating wastewater. Based on principles, these include physical, chemical, and biological methods. Based on steps, they can be divided into primary treatment, secondary treatment, and tertiary treatment. Primary treatment is pretreatment, often using physical and chemical methods to initially treat wastewater to meet the water quality standards for secondary treatment. A screen is a device used to filter and intercept solid impurities in wastewater. It is usually located at the front end of the wastewater treatment system. Its main function is to remove larger contaminants such as weeds, paper, and plastic bags to prevent these substances from entering subsequent treatment equipment and affecting the treatment effect and normal operation of the equipment. Screens are mainly divided into three categories: coarse screens, medium screens, and fine screens. There are three types: manual screens, mechanical screens, and hydraulic cleaning screens. There are also various structural forms of screens, such as rake-type, circulating screens, arc-shaped screens, rotary screens, drum-type screens, rotating screens, toothed rake-type screens, and stepped screens.

[0003] The existing technology has the following problems:

[0004] In existing automatic cleaning bar screen devices, the bar screen is driven by a drive structure. As the bar screen moves, it also removes and transports dirt such as weeds, paper, and plastic bags from the sewage. During the dirt transport process, the dirt on the bar screen is cleaned by spraying with nozzles in the cleaning structure. However, this process can result in some dirt not being completely removed. In addition, the dirt can easily become disordered and scattered during the rinsing process, making it difficult to collect the dirt later.

[0005] Therefore, we need an automatic cleaning screen device to solve the above problems. Summary of the Invention

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As shown in Figures 1 to 5, this utility model provides an automatic cleaning bar screen device, which includes a sewage tank 1 as the main container of the device. The lower left and right sides of the tank are respectively connected to an inlet pipe 2 and an outlet pipe 3. Sewage enters the sewage tank 1 from the inlet pipe 2, and the treated water is discharged from the outlet pipe 3. In addition, the inlet pipe 2 is installed and connected to the sewage pool, and the outlet pipe 3 is installed and connected to the filtration equipment. The inner wall of the sewage tank 1 has sliding grooves at the front and back, which serve as the sliding installation base for the subsequent cleaning components 5.

[0027] The drive assembly 4 includes a motor 41, whose outer surface is fixedly connected to the surface of the sewage tank 1. Its output shaft passes through the inside of the sewage tank 1 and is movably connected. The output shaft is fixedly connected to a column 42. Three support plates 43 are fixedly connected in a ring array on the outer surface of the column 42. The support plates 43 facilitate the installation of the cylindrical grille 44. The end faces of the three support plates 43 are fixedly connected to the inner side of the cylindrical grille 44. Several fixed columns 45 are fixedly connected in a ring array on the outer surface of the cylindrical grille 44. The fixed columns 45 facilitate the removal of weeds, paper, and plastic bags from the sewage after they come into contact with the cylindrical grille 44. The outer surface of the lower fixed column 45 overlaps with the lower surface of the inner wall of the sewage tank 1. When the motor 41 starts, it drives the column 42 to rotate, which in turn drives the cylindrical grille 44 to rotate through the support plates 43, thus cleaning weeds, paper, and plastic bags from the sewage.

[0028] Example 2: As shown in Figures 1 to 5, the cleaning component 5 includes a connecting plate 51 in an inclined state, with several interconnected grooves 52 on its left side. The grooves 52 facilitate the movement of the column 42 through the grooves 52 when the cylindrical grid 44 rotates, preventing the column 42 from colliding with the connecting plate 51. The left side of the connecting plate 51 is provided with an inclined surface 53, the outer surface of which overlaps with the outer surface of the cylindrical grid 44. The connecting plate 51 facilitates the scraping and cleaning of dirt such as weeds, paper, and plastic bags on the surface of the cylindrical grid 44. Due to the inclined state of the connecting plate 51, the scraped dirt such as weeds, paper, and plastic bags fall downwards onto the conveyor belt 63 in the conveying component 6, which facilitates the conveying of the cleaned dirt.

[0029] The connecting plate 51 is fixedly connected to sliders 54 on both the front and rear sides. The outer surface of the sliders 54 is slidably connected to the inside of the chute in the sewage tank 1, so that the connecting plate 51 can slide up and down along the chute for easy installation. The upper surface of the front and rear sliders 54 is fixedly connected to elastic plates 55. The outer surface of the elastic plates 55 extends to the outside of the chute. The upper surface of the outer surface is fixedly connected to positioning posts 57. In addition, the positioning posts 57 are made of rubber. An installation block 56 is set in front of the positioning post 57. The lower surface of the installation block 56 is fixedly connected to the surface of the sewage tank 1. An insertion hole is opened in the middle of its outer surface. The inside of the insertion hole is inserted into the outer surface of the positioning post 57. By inserting the positioning post 57 into the insertion hole, the connecting plate 51 can be installed, removed and replaced. When disassembly is required, the worker pushes the elastic plate 55, causing the elastic plate 55 to deform and bend. At the same time, the positioning post 57 moves out of the installation block 56 and moves upward, thereby completing the disassembly operation of the connecting plate 51.

[0030] Example 3: As shown in Figures 1 to 5, the conveying assembly 6 includes a second motor 61, whose outer surface is fixedly connected to the surface of the sewage tank 1. The output shaft passes through the inside of the sewage tank 1 and is movably connected. Several rotating rollers 62 are each movably connected to a connecting shaft. The outer surface of the connecting shaft is fixedly connected to the inner wall of the sewage tank 1. The front end of one of the connecting shafts is fixedly connected to the output end of the second motor 61. The outer surface of the several rotating rollers 62 is provided with a conveyor belt 63. This structure facilitates the conveying of dirt scraped off from the cylindrical grid 44 to the collection assembly 7. In addition, the specific structure of the conveying assembly 6 is existing technology.

[0031] The collection component 7 includes a guide plate 73, with rotating shafts 72 fixedly connected to its front left and right sides. The outer surface of the left rotating shaft 72 penetrates the interior of the sewage tank 1 and is movably connected, while the outer surface of the right rotating shaft 72 penetrates the interior of the collection box 71 and is movably connected, giving the guide plate 73 a movable feature for easy use in subsequent structures. A spring 74 is fixedly connected to the rear side of the lower surface of the guide plate 73, and the lower end of the spring 74 is fixedly connected to the inner wall of the collection box 71. A motor 75 is fixedly connected to the rear right side of the inner wall of the collection box 71, and the output shaft of the motor 75 is fixedly connected to a cam 76. Impurities conveyed by the conveyor belt 63 fall onto the guide plate 73. The motor 75 starts and drives the cam 76 to rotate. The cam 76 intermittently squeezes the guide plate 73, and with the elasticity of the spring 74, the guide plate 73 swings up and down, accelerating the discharge speed of the dirt. In addition, during use, a container containing the collection can be placed in front of the collection box 71. After the dirt is discharged, it falls into the container, thus completing the dirt collection effect.

[0032] In addition, motor 1 (41), motor 2 (61), and motor 3 (75) are electrically connected by power lines.

[0033] Working principle: In use, the motor 41 is started first. Due to the setting of the column 42 and the support plate 43, the cylindrical screen 44 and the fixed column 45 are rotated, thereby cleaning the dirt such as weeds, paper, and plastic bags in the sewage tank 1. The dirt is attached to the outer surface of the cylindrical screen 44 and the fixed column 45. When the cylindrical screen 44 rotates to the appropriate position, the connecting plate 51 facilitates the scraping and cleaning of the dirt on the surface of the cylindrical screen 44 and the fixed column 45. After scraping and cleaning, due to the action of the connecting plate 51 in the tilted state, the scraped dirt falls onto the conveyor belt 63 and is transported by the conveying component 6. Then, the dirt is transported into the collection box 71. The motor 75 is started, which drives the cam 76 to rotate. Due to the elastic setting of the spring 74, the guide plate 73 vibrates, thereby speeding up the discharge speed of the collected dirt and dropping it into the container, thus completing the dirt collection work.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
