Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically a sewage treatment device for municipal engineering. Background Technology

[0002] Wastewater treatment is a crucial link in protecting water resources, maintaining the ecological environment, and safeguarding human health. Its core objective is to remove pollutants from wastewater through physical, chemical, and biological methods so that it meets discharge standards or can be reused as a resource.

[0003] In daily life, a large amount of sewage is discharged, and some of this sewage flows to sewage treatment centers. After a series of treatments at the sewage treatment centers, it is discharged into the natural environment. Filtration devices are used to separate impurities in the sewage. However, most commonly used filtration devices allow sewage to pass through the filter from top to bottom under the action of gravity. As a result, the filtered impurities will accumulate on the filter, which can easily cause the filter to become clogged, affecting the efficiency of subsequent treatment. Moreover, it is not convenient to clean the filter when it is clogged.

[0004] Therefore, this utility model provides a sewage treatment device for municipal engineering. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The sewage treatment device for municipal engineering of this utility model includes a filter tank. A pair of water-separating plates are fixedly connected inside the filter tank, and a filter plate is installed between the pair of water-separating plates. An overflow trough is opened in the middle of the filter tank. The overflow trough is located between the pair of water-separating plates and is higher than the filter plate. A flow channel is fixedly connected to the outside of the filter tank. A sedimentation tank is provided outside the filter tank. A drain outlet is opened at the bottom of the side wall of the filter tank. A plug is detachably installed on the side of the drain outlet located outside the filter tank. Through the above structure, sewage passes through the filter plate from bottom to top, so that some impurities will not easily adhere to the bottom of the filter plate, reducing the speed at which the filter plate is blocked by impurities. When there are too many impurities below the filter plate, the plug can be opened to drain the water and impurities and clean the filter plate. It is convenient to use.

[0007] Preferably, the sedimentation tank is equipped with a detachable partition, the partition has multiple through slots in the middle, the bottom of the partition is slidably connected to multiple closed plates, and the top of the multiple closed plates is fixedly connected to a first operating rod. With the above structure, the sedimented impurities and sewage can be easily separated so that they can be treated separately.

[0008] Preferably, a support plate is detachably installed between the pair of water-separating plates. A second operating rod is fixed to the top of the support plate. The filter plates are a pair and are placed on the support plate. A pair of pressure plates are provided on the filter plates. With the above structure, the second operating rod can be struck with a tool to make the support plate and the filter plate vibrate. The vibration will loosen the impurities attached to the bottom of the filter plate, so that these impurities can be more easily discharged from the filter tank with the water flow, thereby improving the cleaning effect on the filter plate.

[0009] Preferably, a connecting sleeve is fixedly connected to a pair of pressure plates near the second operating rod, a pair of protrusions are fixedly connected to the middle of the second operating rod, and a sleeve is threadedly connected to the middle of the second operating rod. With the above structure, the filter plate can be easily disassembled and assembled, so that the filter plate can be finely cleaned or replaced when it is severely clogged.

[0010] Preferably, one side of the sedimentation tank is open, and a fitting groove is provided at the open part of the sedimentation tank. A baffle is detachably installed in the middle of the fitting groove. With the above structure, the remaining sewage and impurities in the sedimentation tank can be easily cleaned, improving the ease of use of the device.

[0011] Preferably, a first adhesive strip is fixed to the inner wall of the fitting groove, and a second adhesive strip is fixed to the bottom of the fitting groove. With the above structure, the sealing effect can be improved and the occurrence of sewage leakage can be reduced when the baffle is inserted into the fitting groove.

[0012] Preferably, both ends of the bottom of the fitting groove are provided with impurity discharge ports, which are set through the sedimentation tank. With the above structure, impurities that have fallen into the fitting groove can be easily pushed away from the impurity discharge ports with the help of tools, reducing the impact of impurities remaining in the fitting groove on the sealing effect after the baffle is installed.

[0013] The beneficial effects of this utility model are as follows: 1. The municipal engineering sewage treatment device described in this utility model, through the arrangement of a filter tank, a baffle plate, a filter plate, an overflow trough, a flow channel, a sedimentation tank, a drain outlet, and a plug, allows sewage to pass through the filter plate from bottom to top, preventing some impurities from easily adhering to the bottom of the filter plate and reducing the speed at which the filter plate is blocked by impurities. When there are too many impurities below the filter plate, the plug can be opened to drain the water and impurities and clean the filter plate, making it convenient to use.

[0014] 2.

[0018] 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.

[0019] like Figures 1 to 2As shown in the figure, a sewage treatment device for municipal engineering according to an embodiment of the present invention includes a filter tank 1. A pair of baffle plates 12 are fixedly connected inside the filter tank 1, and a filter plate 13 is installed between the pair of baffle plates 12. An overflow trough 14 is opened in the middle of the filter tank 1, located between the pair of baffle plates 12 and higher than the filter plate 13. A flow channel 15 is fixedly connected to the outside of the filter tank 1. A sedimentation tank 16 is provided outside the filter tank 1. A drain outlet 17 is opened at the bottom of the side wall of the filter tank 1. The drain outlet 17 is located outside the filter tank 1. A plug 18 is detachably installed on one side of the filter. During operation, wastewater is injected into the filter tank 1 from the opposite sides of a pair of baffle plates 12. After entering the filter tank 1, the liquid level gradually rises. At this time, some wastewater will pass through the filter plate 13 and flow between the pair of baffle plates 12. Impurities in this wastewater will be filtered by the filter plate 13 and remain below the filter plate 13. As the liquid level gradually rises, the filtered wastewater will overflow from the overflow tank 14 and be discharged through the flow channel 15. After long-term use, the area below the filter plate 13 can be... The filter plate 13 may become clogged with impurities, reducing its filtration efficiency. In this case, the injection of wastewater into the filter tank 1 can be stopped, and the plug 18 can be opened to allow the wastewater in the filter tank 1, mixed with the impurities filtered below the filter plate 13, to flow into the sedimentation tank 16 through the drain outlet 17. At the same time, the wastewater above the filter plate 13 will also flow downwards through the filter plate 13 again, flushing down the impurities below the filter plate 13 and cleaning the filter plate 13. When a large amount of impurities mixed with wastewater falls into the sedimentation tank 16, the drain outlet 17 can be sealed again with the plug 18, and then wastewater can be injected into the filter tank 1 for filtration. The wastewater falling into the sedimentation tank 16 will settle over time, with some impurities settling to the bottom for subsequent treatment. Through the above structure, the wastewater passes through the filter plate 13 from bottom to top, preventing some impurities from easily adhering to the bottom of the filter plate 13 and reducing the speed at which the filter plate 13 becomes clogged with impurities. When there are too many impurities below the filter plate 13, the plug 18 can be opened to drain the water and impurities and clean the filter plate 13. This method is quite convenient to use.

[0020] like Figures 1 to 5As shown, a partition 2 is detachably installed inside the sedimentation tank 16. Multiple through slots 21 are opened in the middle of the partition 2. Multiple sealing plates 22 are slidably connected to the bottom of the partition 2. A first operating rod 23 is fixed to the top of the multiple sealing plates 22. During operation, when sewage mixed with a large amount of impurities enters the sedimentation tank 16 and completes sedimentation, a large amount of impurities will fall below the partition 2 and the sealing plates 22. When it is necessary to extract the sewage with fewer impurities in the upper layer, the sealing plates 22 can be moved by the first operating rod 23 to block the multiple through slots 21, separating the upper sewage from the lower impurities. Thus, when extracting the sewage above, the lower impurities will not be easily extracted as well. After the sewage above is extracted, the partition 2 and the sealing plates 22 are removed from the sedimentation tank 16 to clean the large amount of impurities and small amount of sewage below. Through the above structure, the sedimented impurities and sewage can be easily separated for separate treatment.

[0021] like Figures 1 to 3 As shown, a support plate 3 is detachably installed between a pair of water-separating plates 12. A second operating rod 31 is fixed to the top of the support plate 3. A pair of filter plates 13 are placed on the support plate 3. A pair of pressure plates 32 are provided on the filter plates 13. During operation, when the sewage in the filter tank 1 is discharged to the sedimentation tank 16 through the drain outlet 17, the second operating rod 31 can be struck with a tool to make the support plate 3 and the filter plate 13 vibrate. The vibration will loosen the impurities attached to the bottom of the filter plate 13, so that these impurities can be more easily discharged from the filter tank 1 with the water flow, thereby improving the cleaning effect on the filter plate 13.

[0022] like Figures 1 to 3 As shown, a pair of pressure plates 32 are fixedly connected to a connecting sleeve 4 near the second operating rod 31. A pair of protrusions 41 are fixedly connected to the middle of the second operating rod 31. A sleeve 42 is threadedly connected to the middle of the second operating rod 31. After long-term use, the support plate 3 and the filter plate 13 can be removed from the filter tank 1. Then, the sleeve 42 is rotated to raise the sleeve 42. Subsequently, the pair of pressure plates 32 and the filter plate 13 are removed. The filter plate 13 is then cleaned or replaced. After completion, the filter plate 13 is placed on the support plate 3, and the pair of second operating rods 31 are pressed on the filter plate 13 so that the pair of connecting sleeves 4 cover the second operating rods 31. The protrusions 41 are embedded in the grooves on the connecting sleeves 4 for positioning. Then, the sleeve 42 is rotated to lower the filter plate 13 so that the sleeve 42 covers the pair of connecting sleeves 4, thus fixing the filter plate 13. With the above structure, the filter plate 13 can be easily disassembled and assembled so that it can be cleaned or replaced when it is severely clogged.

[0023] like Figures 1 to 6As shown, one side of the sedimentation tank 16 is open. A fitting groove 5 is provided at the open part of the sedimentation tank 16. A baffle 51 is detachably installed in the middle of the fitting groove 5. During operation, after the sewage above the baffle 2 is extracted, the baffle 2 and the sealing plate 22 are removed from the sedimentation tank 16. Then, the baffle 51 is removed to open one side of the sedimentation tank 16. At this time, the remaining sewage and impurities in the sedimentation tank 16 can be scraped off directly with the help of cleaning tools. Through the above structure, the remaining sewage and impurities in the sedimentation tank 16 can be easily cleaned, improving the ease of use of the device.

[0024] like Figures 1 to 6 As shown, a first adhesive strip 6 is fixed to the inner wall of the fitting groove 5, and a second adhesive strip 61 is fixed to the bottom of the fitting groove 5. With the above structure, the sealing effect can be improved and the occurrence of sewage leakage can be reduced when the baffle 51 is inserted into the fitting groove 5.

[0025] like Figure 6 As shown, both ends of the bottom of the fitting groove 5 are provided with impurity discharge ports 7, which are set through the sedimentation tank 16. With the above structure, impurities that have fallen into the fitting groove 5 can be easily pushed away from the impurity discharge ports 7 with the help of tools, reducing the impact of impurities remaining in the fitting groove 5 on the sealing effect of the baffle 51 after installation.

[0026] During operation, wastewater is injected into the filter tank 1 from the opposite sides of a pair of baffle plates 12. As the wastewater enters the filter tank 1, the liquid level gradually rises. At this time, some wastewater passes through the filter plate 13 and flows between the baffle plates 12. Impurities in this wastewater are filtered by the filter plate 13 and remain below it. As the liquid level continues to rise, the filtered wastewater overflows from the overflow tank 14 and is discharged through the flow channel 15. After prolonged use, impurities may clog the area below the filter plate 13, reducing the filtration efficiency. In this case, the injection of wastewater into the filter tank 1 can be stopped, and the plug 18 can be opened, allowing the wastewater in the filter tank 1, mixed with the impurities filtered below the filter plate 13, to flow into the sedimentation tank 16 through the drain outlet 17. Simultaneously, the wastewater above filter plate 13 will pass through filter plate 13 again, washing away the impurities below filter plate 13, thus cleaning filter plate 13. After a large amount of impurities mixed with wastewater falls into sedimentation tank 16, the drain outlet 17 is sealed with plug 18, and wastewater continues to be injected into filter tank 1 for filtration. The wastewater falling into sedimentation tank 16 will settle over time, with some impurities settling to the bottom for subsequent treatment. After the wastewater mixed with a large amount of impurities enters sedimentation tank 16 and completes sedimentation, a large amount of impurities will fall below partition plate 2 and sealing plate 22. When it is necessary to extract the upper layer of wastewater with fewer impurities, the sealing plate 22 can be moved by the first operating rod 23 to block multiple channels 21, thus removing the upper layer of wastewater. The upper layer of wastewater is separated from the lower layer of impurities, so that when the upper wastewater is pumped out, the lower layer of impurities will not be easily pumped out as well. After the upper wastewater is pumped out, the partition plate 2 and the sealing plate 22 are removed from the sedimentation tank 16 to clean the large amount of impurities and small amount of wastewater below. During the process of discharging the wastewater in the filter tank 1 into the sedimentation tank 16 through the drain outlet 17, the second operating lever 31 can be tapped with a tool to make the supporting plate 3 and the filter plate 13 vibrate. The vibration loosens the impurities attached to the bottom of the filter plate 13, so that these impurities can be more easily discharged from the filter tank 1 with the water flow. After long-term use, the supporting plate 3 and the filter plate 13 can be removed from the filter tank 1, and then the sleeve 42 can be rotated to make the sleeve 4 2. After rising, remove the pair of pressure plates 32 and filter plates 13. Clean or replace the filter plates 13. After completion, place the filter plates 13 on the support plate 3. Then press the pair of second operating rods 31 on the filter plates 13 so that the pair of connecting sleeves 4 cover the second operating rods 31. The protrusions 41 will be embedded in the grooves on the connecting sleeves 4 to achieve positioning. Then rotate the sleeve 42 to lower it so that the sleeve 42 covers the pair of connecting sleeves 4, thus fixing the filter plates 13. After the sewage above the partition 2 is removed, remove the partition 2 and the sealing plate 22 from the sedimentation tank 16. Then remove the baffle 51 to open one side of the sedimentation tank 16. At this time, the remaining sewage and impurities in the sedimentation tank 16 can be scraped off directly with the help of cleaning tools.
