Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically a sewage sedimentation and separation device. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products that are lost with the water, as well as pollutants generated during the production process. Therefore, for environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage.

[0003] For example, Chinese patent CN215137164U discloses a wastewater sedimentation and separation device. This device includes a tank, a primary overflow section, a secondary overflow section, and a sedimentation structure. The primary and secondary overflow sections divide the tank into a sedimentation tank, a primary buffer tank, and a secondary buffer tank. Wastewater flows into the sedimentation tank and is guided by the overflow from the primary and secondary overflow sections into the primary and secondary buffer tanks. The sedimentation tank and the primary buffer tank are equipped with a sedimentation structure. Sludge settles in the sedimentation structure in the sedimentation tank and the primary buffer tank and is discharged separately. Water is discharged from the secondary buffer tank. The primary and secondary overflow sections combine to form a multi-level, multi-layer overflow, which is then settled separately by the sedimentation structure. This results in a lower solid content in the water after sedimentation and separation. The entire device is simpler to operate, and the separation process no longer requires frequent manual cleaning of the traditional inclined plate device, reducing labor intensity and improving production efficiency.

[0004] However, in this scheme, even though the sediment after sewage sedimentation adopts multi-layer stratified sedimentation, the sediment at the bottom still needs to be cleaned manually. This manual cleaning of the bottom is time-consuming, labor-intensive, and inefficient. In addition, the device does not have a filtering function, and foreign objects that are not easy to settle in the sewage are not easy to clean. If the filter plate is used directly, it still needs to be cleaned manually. Therefore, we propose a sewage sedimentation and separation device. Utility Model Content

[0020] Please see Figures 1 to 4A wastewater sedimentation and separation device includes a sedimentation tank 1 and an inlet pipe 2 disposed above the outer wall of the sedimentation tank 1. Inside the sedimentation tank 1, there is a filter plate 3, a guide block 4, and a first pusher plate 5. The filter plate 3 is inclinedly disposed above the interior of the sedimentation tank 1, and the inlet pipe 2 is located on the higher side above the filter plate 3. A through groove 6 is opened on the lower side of the sedimentation tank 1 facing the filter plate 3. A receiving groove 7, fixedly connected to the sedimentation tank 1, is provided on one side of the through groove 6. A filter groove 8 is disposed within the receiving groove 7, and the filter groove 8 is located below the filter plate 3. The guide block... The guide blocks 4 are in the shape of right angle triangles and are symmetrically arranged in groups on both sides of the bottom of the sedimentation tank 1. The first push plate 5 is in the shape of an inverted trapezoid and is located between the two guide blocks 4. The bottom and the two symmetrical sides of the first push plate 5 are respectively attached to the bottom of the sedimentation tank 1 and the two guide blocks 4. The sedimentation tank 1 is provided with a first telescopic device 9 that is fixedly connected to the first push plate 5. The sedimentation tank 1 is provided with a sewage outlet 10 on the side away from the first telescopic device 9. The sedimentation tank 1 is provided with a pump 11 that is connected to the sewage outlet 10.

[0021] In this embodiment: wastewater is transported to the top of the filter plate 3 in the sedimentation tank 1 through the inlet pipe 2. The filter plate 3 plays a filtering role, and the wastewater flows downward from the higher side of the filter plate 3, which makes it easy for the filtered foreign matter above the filter plate 3 to be automatically flushed into the filter tank 8 through the through groove 6, without the need for manual cleaning of the filter plate 3. While realizing the filtering function, the device can automatically clean the filter plate 3, which can easily improve the filtration quality of the filter plate 3 for wastewater.

[0022] When the sediment in the sewage settles downwards, the inclined surface of the guide block 4 plays a guiding role. Foreign objects that are easy to settle gather between the two guide blocks 4. The first push plate 5 is activated, which easily pushes foreign objects far away from the sewage outlet 10 toward the sewage outlet 10. Finally, the pump 11 is activated, which easily and quickly cleans the sediment inside the sedimentation tank 1, making the sedimentation tank 1 easy to clean, saving manpower and having high cleaning efficiency.

[0023] The first telescopic device 9, the second telescopic device 13, the first lifting device 15, and the second lifting device 16 are electric telescopic rods, pneumatic telescopic rods, or hydraulic telescopic rods.

[0024] As a technical optimization of this utility model, a second push plate 12 is provided on the filter plate 3, and a second telescopic device 13 is provided on the side of the sedimentation tank 1 away from the through groove 6 and is fixedly connected to the second push plate 12.

[0025] In this embodiment: when the second telescopic device 13 is activated, the second push plate 12 slides on the filter plate 3, which makes it easy to push the foreign objects on the filter plate 3 that have not been rinsed by water into the filter tank 8, thereby improving the filtration quality of the filter plate 3.

[0026] As a technical optimization of this utility model, a movable plate 14 is hinged to the bottom of the filter tank 8 on the side away from the through groove 6. A first lifting device 15 and a second lifting device 16 are respectively provided on both sides of the bottom of the receiving groove 7. The output ends of the first lifting device 15 and the second lifting device 16 are both hinged to the bottom of the receiving groove 7.

[0027] In this embodiment: Activating the first lifting device 15 and the second lifting device 16 moves the filter tank 8 upward. When the filter tank 8 is completely removed from the receiving tank 7, the upper part of the movable plate 14 is no longer restricted by the filter tank 8 and will rotate 90 degrees to be parallel to the ground and automatically open the receiving tank 7. Activating the second lifting device 16 again raises the side of the filter tank 8 away from the movable plate 14, making it easier for the foreign objects collected inside the filter tank 8 to fall downward automatically, thus achieving the purpose of automatically cleaning the filter tank 8. To prevent the filtered foreign objects from falling to the ground, a receiving frame can be placed below the receiving tank 7 to easily collect the filtered foreign objects. After cleaning, when the first lifting device 15 and the second lifting device 16 move the filter tank 8 toward the receiving frame, the movable plate 14 will automatically reset due to the restriction of the filter tank 8.

[0028] It should be noted that the width of the movable plate 14 is greater than the width of the filter tank 8, ensuring that the movable plate 14 will not rotate into the interior of the filter tank 8. The movable plate 14 can only rotate 90 degrees to the side away from the filter tank 8. The first lifting device 15 and the second lifting device 16 are fixedly connected to the receiving tank 7 and movably connected to it, respectively. The output ends of the first lifting device 15 and the second lifting device 16 are movably connected to the bottom of the filter tank 8.

[0029] As a technical optimization of this utility model, the bottom of the receiving tank 7 is funnel-shaped, and the bottom of the receiving tank 7 is connected to the guide pipe 17, the other end of the guide pipe 17 is connected to the sedimentation tank 1.

[0030] In this embodiment: the filter tank 8 is located inside the receiving tank 7 to prevent sewage from flowing outside the sedimentation tank 1. The receiving tank 7 plays a role in collecting water, and the guide pipe 17 facilitates the automatic transport of sewage accumulated inside the receiving tank 7 to the sedimentation tank 1.

[0031] As a technical optimization of this utility model, a drain pipe 18 is provided on the outer wall of the sedimentation tank 1.

[0032] In this embodiment, the wastewater that has settled inside the sedimentation tank 1 can be easily discharged through the drain pipe 18.

[0033] As a technical optimization of this utility model, a first guide plate 19 and a second guide plate 20 are fixedly connected to the inner wall of the sedimentation tank 1 above the first push plate 5; the first guide plates 19 are symmetrically arranged in groups on both sides of the sedimentation tank 1, and the distance between the upper ends of the two first guide plates 19 is greater than the distance between their lower ends; the second guide plate 20 is located below the two first guide plates 19, and the second guide plate 20 has an inverted V-shaped structure; the drain pipe 18 is located above the first guide plate 19.

[0034] In this embodiment: when the pump 11 is started to discharge the sediment, the first guide plate 19 and the second guide plate 20 can block the foreign objects (such as fine sand and sludge) that are settled below, making it difficult for the foreign objects to float upwards; and when the drain pipe 18 is opened, it is easy to improve the quality of the clear water settled above.

[0035] Working principle: Wastewater is transported to the sedimentation tank 1 above the filter plate 3 through the inlet pipe 2. The filter plate 3 performs the filtering function, and the wastewater flows downward from the higher side of the filter plate 3, which facilitates the automatic flushing of the filtered foreign matter above the filter plate 3 into the filter tank 8 through the through groove 6. By activating the second telescopic device 13, the second push plate 12 slides on the filter plate 3, which facilitates the automatic cleaning of foreign matter on the filter plate 3 that has not been flushed by water, and pushes the foreign matter into the filter tank 8, improving the filtration quality of the filter plate 3. Activating the first lifting device 15 and the second lifting device 16 moves the filter tank 8 upward. When the receiving trough 7 is completely removed from the receiving trough 7, the area above the movable plate 14 is no longer filtered. The limiting mechanism of tank 8 will rotate 90 degrees to be parallel to the ground and automatically open the receiving tank 7; the second lifting device 16 will be activated again to raise the side of the filter tank 8 away from the movable plate 14, so that the foreign objects collected inside the filter tank 8 can fall down automatically, thus achieving the purpose of automatically cleaning the filter tank 8. When the sediment in the sewage settles down, the inclined surface of the guide block 4 plays a guiding role, and the foreign objects that are easy to settle gather between the two guide blocks 4. The first push plate 5 is activated to push the foreign objects far away from the sewage outlet 10 towards the sewage outlet 10. Finally, the pump 11 is activated to quickly clean the sediment inside the sedimentation tank 1, so that the sedimentation tank 1 can be easily cleaned, saving manpower and with high cleaning efficiency.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
