Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically relating to a self-cleaning sewage treatment bar device. Background Technology

[0002] Wastewater is a common household waste in daily life, and its treatment is an indispensable part of modern urban and rural development. Domestic sewage contains a large amount of organic matter, nutrients, pathogens, and chemicals. If discharged directly without treatment, it will lead to eutrophication of water bodies, causing excessive algae growth, consuming oxygen in the water, and thus damaging aquatic ecosystems, resulting in the death of fish and other aquatic organisms. Against the backdrop of global water scarcity, treated sewage can serve as a renewable resource. After proper treatment, it can be used for agricultural irrigation, industrial production, landscaping, and in some cases, after advanced treatment, it can even be used as a supplement to drinking water sources, thereby alleviating water resource pressure. Therefore, sewage treatment is of paramount importance. In the sewage treatment process, screens are used to intercept and filter floating garbage on the water surface.

[0003] In the process of intercepting garbage, the openings of existing sewage treatment screens are easily clogged as more and more garbage is intercepted. In this case, staff need to clean the screens every shift. However, manual operation is very troublesome, time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning wastewater treatment bar device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning sewage treatment bar device, comprising a support platform, a bar plate, a cleaning component, a conveying component, and a collection box. The bar plate is fixedly installed on one side of the support platform. The cleaning component includes a rotating shaft rotatably installed in the top of the bar plate, a first driving component for driving the rotating shaft to rotate, a support base fixedly connected to both ends of the rotating shaft, a cleaning plate slidably installed on one side of the support base, and a second driving component for driving the cleaning plate to slide. The conveying assembly includes a conveying pipe fixedly installed on one side of the grid plate, a conveying component disposed inside the conveying pipe, and an outlet pipe fixedly connected to the upper end of the conveying pipe. The collection box is fixedly installed on the support platform, and a wire mesh basket is attached to the top of the collection box. The lower end of the outlet pipe extends above the wire mesh basket.

[0006] In a preferred embodiment, the first driving component includes a first motor fixedly mounted on one side of the top of the grating plate, a worm fixedly connected to the output end of the first motor, and a worm wheel fixedly connected to the middle of the rotating shaft, wherein the worm and the worm wheel are meshed together.

[0007] In a preferred embodiment, the second driving component includes a lead screw rotatably mounted in the support base and a second motor for driving the lead screw to rotate, with one end of the cleaning plate sleeved on the lead screw and threadedly connected to the lead screw.

[0008] In a preferred embodiment, the cleaning plate has several through holes.

[0009] In one preferred embodiment, the conveying component includes an auger rotatably mounted inside a conveying pipe and a third motor for driving the auger to rotate.

[0010] In a preferred embodiment, a drain pipe is fixedly connected to the bottom of the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This self-cleaning wastewater treatment bar screen device, through the arrangement of cleaning components, conveying components, and collection boxes, allows the first drive component to rotate the shaft when the bar screen intercepts a certain amount of waste. This shaft rotates the support base to be perpendicular to the bar screen, at which point the cleaning plate is positioned on the side of the bar screen that has intercepted waste. Then, the first drive component can be activated to move the cleaning plate toward the conveying pipe, allowing the cleaning plate to clean the intercepted waste into the conveying pipe. At the same time, the conveying component is activated to transport the waste entering the conveying pipe upwards. When the waste is conveyed to the top of the conveying pipe, it slides along the outlet pipe into the mesh basket. Workers can then periodically remove the mesh basket to transfer the collected waste, eliminating the need for manual cleaning of the bar screen, saving time and effort, and improving work efficiency. This self-cleaning sewage treatment bar device, through the setting of the first driving component, can start the first motor to drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the support base to rotate. When it is not necessary to clean the garbage, the cleaning plate can be lifted, thereby avoiding contact between the cleaning plate and the garbage. Attached Figure Description

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-3 This utility model provides a self-cleaning sewage treatment bar device, including a support platform 1, a bar plate 2, a cleaning component 3, a conveying component 4, and a collection box 5. The support platform 1 is fixed on the water surface, and the bar plate 2 is fixedly installed on one side of the support platform 1. The bar plate 2 is used to intercept and filter garbage floating on the water surface.

[0017] Specifically, the cleaning assembly 3 includes a rotating shaft 31 rotatably mounted inside the top of the grating plate 2, a first driving member 32 for driving the rotating shaft 31 to rotate, a support base 33 fixedly connected to both ends of the rotating shaft 31, a cleaning plate 34 slidably mounted on one side of the support base 33, and a second driving member 35 for driving the cleaning plate 34 to slide. The conveying assembly 4 includes a conveying pipe 41 fixedly mounted on one side of the grating plate 2, a conveying member 42 disposed inside the conveying pipe 41, and an outlet pipe 43 fixedly connected to the upper end of the conveying pipe 41. The outlet pipe 43 is arranged at an angle. The collection box 5 is fixedly mounted on the support platform 1. A wire basket 51 is attached to the top of the collection box 5. The lower end of the outlet pipe 43 extends above the wire basket 51. Through the arrangement of the cleaning assembly 3, the conveying assembly 4, and the collection box 5... When the grating plate 2 intercepts a certain amount of garbage, the first drive component 32 can be activated to drive the rotating shaft 31 to rotate, so that the rotating shaft 31 drives the support base 33 to rotate perpendicular to the grating plate 2. At this time, the cleaning plate 34 will be on the side of the grating plate 2 that has intercepted garbage. Then, the first drive component 32 can be activated to drive the cleaning plate 34 to move towards the conveying pipe 41, so that the cleaning plate 34 cleans the intercepted garbage into the conveying pipe 41. At the same time, the conveyor component 42 is activated to convey the garbage entering the conveying pipe 41 upward. When the garbage is conveyed to the top of the conveying pipe 41, the garbage will slide into the wire basket 51 along the outlet pipe 43. The staff can periodically take out the wire basket 51 to transfer the collected garbage. There is no need for manual cleaning of the grating plate 2, which saves time and effort and improves work efficiency.

[0018] Specifically, the first driving component 32 includes a first motor 321 fixedly installed on one side of the top of the grating plate 2, a worm 322 fixedly connected to the output end of the first motor 321, and a worm wheel 323 fixedly connected to the middle of the rotating shaft 31. The worm 322 and the worm wheel 323 are meshed together. By setting the first driving component 32, the first motor 321 can be started to drive the worm 322 to rotate, which in turn drives the worm wheel 323 to rotate, which in turn drives the rotating shaft 31 to rotate. The rotating shaft 31 can then drive the support base 33 to rotate. When it is not necessary to clean up the garbage, the cleaning plate 34 can be adjusted to... Figure 2 This ensures that the cleaning plate 34 does not come into contact with the garbage.

[0019] Specifically, the second driving component 35 includes a lead screw 351 rotatably installed in the support base 33 and a second motor 352 for driving the lead screw 351 to rotate. One end of the cleaning plate 34 is sleeved on the lead screw 351 and threadedly connected to the lead screw 351. By setting the second driving component 35, the second motor 352 can be started to drive the lead screw 351 to rotate, so that the lead screw 351 drives the cleaning plate 34 to slide.

[0020] Specifically, the conveying component 42 includes an auger 421 rotatably installed inside the conveying pipe 41 and a third motor 422 for driving the auger 421 to rotate. By setting the conveying component 42, the third motor 422 can be started to drive the auger 421 to rotate, so that the auger 421 can convey the garbage in the conveying pipe 41 upward.

[0021] The cleaning plate 34 has several through holes 36. When the cleaning plate 34 is cleaning the intercepted garbage, it can flow through the through holes 36, thereby reducing the resistance when the cleaning plate 34 slides.

[0022] The bottom of the collection box 5 is fixedly connected to a drain pipe 52, which allows water in the collection box 5 to be drained.

[0023] The working principle and usage process of this utility model are as follows: First, the grating plate 2 is used to intercept and filter garbage floating on the water surface. When the grating plate 2 intercepts a certain amount of garbage, the first motor 321 can be started to drive the worm gear 322 to rotate, which in turn drives the worm wheel 323 to rotate, which in turn drives the rotating shaft 31 to rotate. The rotating shaft 31 can drive the support base 33 to rotate perpendicular to the grating plate 2. At this time, the cleaning plate 34 will be on the side of the grating plate 2 that has intercepted garbage, and the cleaning plate 34 will be at the end of the grating plate 2 away from the conveying pipe 41. Then, the second motor can be started. 352 drives the lead screw 351 to rotate, causing the lead screw 351 to move the cleaning plate 34 toward the conveying pipe 41, so that the cleaning plate 34 cleans the intercepted garbage into the conveying pipe 41. At the same time, the third motor 422 can be started to drive the auger 421 to rotate, so that the auger 421 conveys the garbage in the conveying pipe 41 upward. When the garbage is conveyed to the top of the conveying pipe 41, the garbage will slide into the wire mesh basket 51 along the outlet pipe 43. The staff can then periodically remove the wire mesh basket 51 to transfer the collected garbage. There is no need for manual cleaning of the grid plate 2, which saves time and effort and improves work efficiency.
