Description

Technical Field

[0001] This utility model relates to the field of river ecological environment, specifically to a sewage treatment device for river ecological environment engineering. Background Technology

[0002] River ecological environment is a comprehensive concept that encompasses natural elements such as river water, riverbed, riverbank and vegetation, as well as the interaction and impact between these elements and human social activities. In river ecological environment engineering, sewage treatment equipment is a key device for restoring and improving water quality and protecting the ecological environment.

[0003] A search revealed a utility model for a wastewater treatment device for water ecological environment management, with announcement number CN220633405U. This device includes an external water purification unit with a connection port on one side. One end of the connection port is threaded to the external water purification unit, while the other end is snapped into a sewage pipe. Simultaneously, a filter plate and a filtration assembly are snapped into the external water purification unit. The filter plate filters out impurities such as stones from the wastewater, while the filtration assembly removes silt and other impurities as water flows through. The design of the filtration assembly, including its plug-and-play mechanism and the snap-fit ​​connection of the filter cotton, allows for easy cleaning or replacement of the filter cotton when it becomes clogged. The debris trapped by the filter plate can be removed by flipping over the cover. This utility model overcomes the shortcomings of traditional wastewater treatment devices, such as the difficulty in cleaning and unclogging clogged filters. Furthermore, its small size and minimal footprint allow for placement at various sewage discharge points, expanding the environmental applicability of the wastewater treatment device.

[0004] Most existing sewage treatment devices used in river ecological environment engineering simply use filter screens and sedimentation to treat sewage during the filtration process. However, relying solely on the sedimentation of sewage itself is not an effective way to treat it. In contrast, the sewage treatment device for water ecological environment governance in the above comparative case only uses a few layers of filter components to filter sewage. However, the effect of simply using filter components to treat sewage is not ideal.

[0005] Therefore, it is necessary to invent a sewage treatment device for river ecological environment engineering to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a sewage treatment device for river ecological environment engineering. Sewage enters through an inlet pipe and first passes through two sets of filter plates in a filter box, filtering out large particles. The filtered sewage then enters a sewage treatment tank. At this point, an appropriate amount of flocculant is added to the inlet on the outer cover and introduced into the sewage treatment tank. The drive motor is then turned on, causing the transmission rod and stirring blades to rotate, fully mixing the sewage and flocculant, thus achieving solid-liquid separation. The separated solid impurities fall to the bottom of the sewage treatment tank. Next, the water pump is turned on, allowing the outlet pipe to extract the separated sewage from the sewage treatment tank. Simultaneously, a filter screen is installed in the connector at one end of the outlet pipe, effectively blocking impurities and preventing blockage. This addresses the problem in the comparative examples of water ecological environment treatment sewage treatment devices mentioned in the background art, which only use a few layers of filter components to filter sewage, and the effect of simple filtration components on sewage treatment is not ideal.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment device for river ecological environment engineering, comprising a sewage treatment tank;

[0008] An inlet assembly is installed on one side of the sewage treatment tank for conveying sewage. A top cover is fixedly connected to the top of the sewage treatment tank. A drive motor is fixedly installed on the top cover. A transmission rod is fixedly connected to the output end of the drive motor. A stirring blade is fixedly connected to the outside of the transmission rod.

[0009] The outlet pipe is installed inside the sewage treatment tank and is used to extract the treated sewage. A water pump is fixedly installed at the upper end of the outlet pipe.

[0010] A cleaning mechanism, installed at the bottom of the sewage treatment tank, is used to clean up impurities.

[0011] Preferably, the water inlet assembly includes a water inlet pipe located on one side of the wastewater treatment tank. A filter box is installed outside the water inlet pipe, and an outer cover is hinged to one side of the filter box. Mounting grooves are provided on both sides of the interior of the filter box, and filter plates are movably connected inside the mounting grooves.

[0012] Preferably, two sets of filter plates are provided, and the two sets of filter plates are movably connected to the filter box.

[0013] Preferably, one end of the water outlet pipe is fixedly connected to a connector, and a filter screen is provided inside the connector.

[0014] Preferably, the cleaning mechanism includes a servo motor, the output end of which is fixedly connected to a connecting block, a connecting rod is fixedly connected to the outside of the connecting block, a scraper is provided below the connecting rod, and a storage groove is provided on the bottom surface of the sewage treatment tank.

[0015] Preferably, a collection box is movably connected inside the storage slot, and a sealing cover is fixedly connected to one side of the collection box, with a sealing strip provided inside the sealing cover.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] By configuring a wastewater treatment tank, inlet assembly, drive motor, transmission rod, stirring blade, outlet pipe, water pump, connector, and filter screen, solid-liquid separation of wastewater can be effectively achieved, thereby improving the wastewater treatment effect. Wastewater enters through the inlet pipe and first passes through two sets of filter plates in the filter box, which can filter out large particles in the wastewater. After filtration, the wastewater enters the wastewater treatment tank. At this time, an appropriate amount of flocculant is added into the inlet on the outer cover and then into the wastewater treatment tank. Then, the drive motor switch is turned on, which drives the transmission rod and stirring blade to rotate, fully mixing the wastewater and flocculant, thereby achieving solid-liquid separation. When the separated solid impurities fall to the bottom of the wastewater treatment tank, the water pump switch is turned on, allowing the outlet pipe to draw out the separated wastewater from the wastewater treatment tank. At the same time, a filter screen is installed in the connector at one end of the outlet pipe, which can effectively block impurities and prevent clogging.

[0018] By combining the wastewater treatment tank with the cleaning mechanism, impurities at the bottom of the tank can be effectively cleaned. A servo motor switch drives the connecting block, connecting rod, and scraper below to rotate, causing the scraper to sweep away impurities from the bottom of the tank and collect them into the collection box inside the storage tank for easy collection and unified processing. As the connecting rod rotates through the connecting block, its upper part contacts the filter screen inside the connector, cleaning impurities from the filter screen surface and preventing clogging.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6 A wastewater treatment device for river ecological environment engineering is shown, including a wastewater treatment tank 1;

[0030] The water inlet assembly 2 is located on one side of the sewage treatment tank 1 and is used to transport sewage. The top cover 3 is fixedly connected to the top of the sewage treatment tank 1. The drive motor 4 is fixedly installed on the top cover 3. The output end of the drive motor 4 is fixedly connected to the transmission rod 5. The outside of the transmission rod 5 is fixedly connected to the stirring blade 6.

[0031] The outlet pipe 7 is installed inside the sewage treatment tank 1 and is used to extract the treated sewage. A water pump 8 is fixedly installed at the upper end of the outlet pipe 7.

[0032] The cleaning mechanism 11, installed at the bottom of the sewage treatment tank 1, is used to clean impurities. By having sewage enter through the inlet pipe 201, it first passes through two sets of filter plates 205 in the filter box 202, which can filter out large particles in the sewage. After that, the filtered sewage enters the sewage treatment tank 1. At this time, an appropriate amount of flocculant is added into the feed port on the outer cover 203 and enters the sewage treatment tank 1. Then, the drive motor 4 is turned on, which drives the transmission rod 5 and the stirring blade 6 to rotate, so that the sewage and flocculant are fully mixed, thereby separating them into solid and liquid. When the separated solid impurities fall to the bottom of the sewage treatment tank 1, the water pump 8 is turned on, and the outlet pipe 7 is used to extract the separated sewage from the sewage treatment tank 1. At the same time, a filter screen 10 is installed in the connector 9 at one end of the outlet pipe 7, which can effectively block impurities and avoid clogging.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the water inlet assembly 2 includes an inlet pipe 201, which is located on one side of the wastewater treatment tank 1. A filter box 202 is installed outside the inlet pipe 201. An outer cover 203 is hinged to one side of the filter box 202. Both sides of the filter box 202 are provided with mounting grooves 204. Filter plates 205 are movably connected inside the mounting grooves 204. By transporting wastewater from the inlet pipe 201 through the two sets of filter plates 205 inside the filter box 202 outside the inlet pipe 201, large particulate impurities in the wastewater can be effectively blocked. The filter box 202 can be opened through the outer cover 203 to clean the large particulate impurities inside.

[0034] like Figure 3 As shown, two sets of filter plates 205 are provided. The two sets of filter plates 205 are movably connected to the filter box 202. The two sets of filter plates 205 can enhance the filtration during sewage transportation. At the same time, the filter plates 205 can be pulled out from the filter box 202 for easy disassembly and cleaning.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a connector 9 is fixedly connected to one end of the outlet pipe 7. A filter screen 10 is installed inside the connector 9. When the water pump 8 is turned on, the sewage separated in the sewage treatment tank 1 is adsorbed through the outlet pipe 7. During the adsorption process, to prevent impurities at the bottom from being adsorbed into the outlet pipe 7, the connector 9 and the filter screen 10 at one end of the outlet pipe 7 can effectively block impurities from being drawn into the outlet pipe 7 together.

[0036] like Figure 2 , Figure 5 and Figure 6As shown, the cleaning mechanism 11 includes a servo motor 1101. The output end of the servo motor 1101 is fixedly connected to a connecting block 1102. A connecting rod 1103 is fixedly connected to the outside of the connecting block 1102. A scraper 1104 is provided below the connecting rod 1103. A collection groove 1105 is provided on the bottom surface of the sewage treatment tank 1. By switching the servo motor 1101 on and off, the connecting block 1102, the connecting rod 1103, and the scraper 1104 below are driven to rotate. This causes the scraper 1104 to clean the impurities at the bottom of the sewage treatment tank 1 and sweep them into the collection box 1106 inside the collection groove 1105 for easy collection and unified treatment. When the connecting rod 1103 rotates through the connecting block 1102, the top of the connecting rod 1103 can also contact the filter screen 10 inside the connector 9 during the rotation process, thereby cleaning the impurities on the surface of the filter screen 10 and preventing clogging.

[0037] like Figure 5 As shown, a collection box 1106 is movably connected inside the collection tank 1105. A sealing cover 1107 is fixedly connected to one side of the collection box 1106. A sealing strip 1108 is provided inside the sealing cover 1107. After the impurities at the bottom of the sewage treatment tank 1 are cleaned into the collection box 1106, the collection box 1106 can be pulled out from the outside of the sewage treatment tank 1 for unified treatment. When the collection box 1106 is pulled out, the sewage separated inside must be completely pumped out before the collection box 1106 can be pulled out. At the same time, the sealing cover 1107 and sealing strip 1108 on the outside of the collection box 1106 can effectively improve the sealing performance. When the collection box 1106 is pulled out, there will be sewage remaining inside, but it doesn't matter, as the sewage and remaining impurities can be poured out together.

[0038] The working principle of this utility model is as follows: First, connect the external power supply. Then, the sewage is transported to the filter box 202 through the inlet pipe 201. Large particles in the sewage are filtered by two sets of filter plates 205 in the filter box 202. The pre-filtered sewage then enters the sewage treatment tank 1. At this point, an appropriate amount of flocculant is added to the feed inlet on the outer cover 203 and introduced into the sewage treatment tank 1. Then, the drive motor 4 is turned on, driving the transmission rod 5 and the stirring blade 6 to rotate, fully mixing the sewage and flocculant, thus achieving solid-liquid separation. The separated solid impurities fall to the bottom of the sewage treatment tank 1 and settle. Then, the drive motor 4 is turned off, and the water pump 8 is turned on, pumping the separated sewage out of the sewage treatment tank 1 through the outlet pipe 7. Simultaneously, a filter screen 10 is installed in the connector 9 at one end of the outlet pipe 7, which can effectively... The system blocks impurities to prevent clogging. When the wastewater is pulled out, the servo motor 1101 switch at the bottom of the wastewater treatment tank 1 can be turned on, which drives the connecting block 1102, connecting rod 1103 and scraper 1104 to rotate. The scraper 1104 can sweep the impurities at the bottom of the wastewater treatment tank 1 into the collection box 1106 in the collection trough 1105. The upper part of the connecting block 1102 can scrape the surface of the filter screen 10 below the connector 9, thus preventing impurities from clogging the surface of the filter screen 10. After the treated wastewater is pulled out, the water pump 8 switch is turned off and the servo motor 1101 switch is turned off. Finally, the collection box 1106 is pulled out from the bottom side of the wastewater treatment tank 1, and the impurities and remaining wastewater in the collection box 1106 are disposed of together. Finally, the external power supply is cut off. In this way, the use process of the wastewater treatment device for the river ecological environment project is completed.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
