Abstract
Description
Technical Field
[0001] This utility model relates to a high-efficiency self-cleaning mud-water separation device, belonging to the field of building construction technology. Background Technology
[0002] With water pollution becoming increasingly serious, wastewater treatment technology is gaining widespread attention as a preventative measure. In construction sites, multiple processes involving water washing, such as formwork pouring, block watering, and stone cutting spraying, result in water streams carrying significant amounts of solid impurities. Whether for water recycling or wastewater purification to meet discharge standards, wastewater treatment is essential.
[0003] Wastewater typically undergoes multi-stage sedimentation and filtration processes before being discharged into the environment or reused to remove dispersed powdery and particulate impurities. Currently, inclined plate / tube sedimentation tanks play a crucial role in treating construction site sludge to improve sedimentation efficiency. However, during operation, suspended solids in the wastewater gradually settle onto the surface of the inclined plates / tubes and the bottom of the tank, forming sludge. Over time, this sludge accumulates, dries, and clogs the inclined plates / tubes and the sludge discharge pipe. Furthermore, excessive sludge volume and heavy particles can easily clog or damage the inclined plates / tubes of the sedimentation tank, ultimately affecting sedimentation efficiency and increasing operating costs. Utility Model Content
[0004] The purpose of this invention is to provide a highly efficient self-cleaning mud-water separation device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Compared with the prior art, the present invention provides a high-efficiency self-cleaning mud-water separation device, including a tank and support legs set at the bottom of the tank. A water inlet pipe is provided on one side of the top of the tank, and a water outlet pipe is provided on the tank. The end of the water outlet pipe extends to the lower part of the tank and is provided with multiple mud-water separators. The multiple mud-water separators are arranged sequentially from top to bottom. When water enters the tank through the water inlet pipe, the sewage flows along the inner wall of the tank to form a swirling flow and moves downward in a spiral shape, increasing the sedimentation time of mud and sand in the sewage.
[0007] Preferably, the number of mud-water separators is 3-5, and the mud-water separators have a funnel-shaped structure with the larger side of the cut facing downwards. The openings on the upper and lower sides of the mud-water separator located at the bottom are closed.
[0008] Preferably, the extension line of the connection between the water outlet side of the inlet pipe and the inner wall of the tank is tangent to the inner wall of the tank.
[0009] Preferably, the water outlet pipe has an L-shaped structure, and the central axis of the vertical part of the water outlet pipe, the central axis of the multiple mud-water separators, and the central axis of the tank body coincide.
[0010] Preferably, an air compressor is installed at the top of the tank, an aeration pipe is installed at the air outlet of the air compressor, and multiple annular pipes are installed at the bottom of the aeration pipes. Each annular pipe has several micro air holes. Air is injected into the annular pipes through the air compressor and the aeration pipes, and the air is discharged through the micro air holes to clean the mud-water separator.
[0011] Preferably, one end of the aeration pipe extends into the tank and passes through the mud-water separator from top to bottom, and the plurality of annular pipes are respectively attached to the inner wall of the mud-water separator to support the mud-water separator.
[0012] Preferably, a drain pipe is provided in the middle of the bottom of the tank.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention can be used as a primary sedimentation assembly connected before the inclined plate sedimentation tank, reducing the processing load of the inclined plate sedimentation tank and extending its service life.
[0015] By using an inlet pipe, when sewage enters the tank, it can flow along the inner wall of the tank to form a swirling flow and move downwards in a spiral shape, which increases the sedimentation time of silt in the sewage and improves the removal rate of silt particles. Due to the increased sedimentation time and increased surface load, it can remove suspended particles in the water more effectively, adapt to various water qualities, save floor space and equipment volume, and help prevent excessive accumulation of sediment at the bottom of the tank and near the outlet, which can cause blockage.
[0016] By setting up multiple sludge-water separators, wastewater can flow upwards into the outlet pipe between two adjacent sludge-water separators. Sludge particles are intercepted on the surface of the sludge-water separators and eventually settle downwards to the bottom of the tank. Under the action of the inclined surface of the sludge-water separator, the effluent flow can be divided into several thin layers. In this case, the Reynolds number of the water flow decreases, and the water flow is in a laminar flow state, which is more stable and less prone to turbulence. This makes it less likely for sludge particles to be stirred up by the water flow, which is conducive to the sedimentation of sludge particles. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution:
[0027] like Figure 1 and Figure 2As shown, a high-efficiency self-cleaning mud-water separation device includes a tank 1 and support legs 2 located at the bottom of the tank 1. A water inlet pipe 3 is provided on one side of the top of the tank 1, and a water outlet pipe 4 is provided on the tank 1. The end of the water outlet pipe 4 extends into the lower part of the tank 1 and is provided with multiple mud-water separators 5. The multiple mud-water separators 5 are arranged sequentially from top to bottom. When water enters the tank 1 through the water inlet pipe 3, the sewage flows along the inner wall of the tank 1 to form a vortex and moves downward in a spiral shape, increasing the sedimentation time of the mud and sand in the sewage, avoiding direct impact of the water flow on the internal structure of the tank, and ensuring the stability and continuity of the vortex.
[0028] Specifically, when water enters tank 1 tangentially from the top, it forms a vortex within the tank. This vortex causes the water to move downwards in a spiral. Due to the presence of the vortex, the trajectory of sediment particles becomes more complex during their movement with the water. Compared to the traditional straight up-down water flow, the particle movement path in the vortex is longer, thus extending the residence time of particles in the tank and increasing the sedimentation time. In the vortex state, the flow velocity near the inner wall of tank 1 is relatively slow, while the flow velocity in the central area is faster. This difference in flow velocity distribution allows particles to utilize the sedimentation space more effectively. Some lighter particles slowly sink along the tank wall area, resulting in more sedimentation time compared to uniform flow. The special flow pattern generated by the vortex helps improve the stability of the water flow. Under high surface loads, a stable flow pattern can reduce water turbulence. Ordinary sedimentation tanks are prone to water turbulence under high surface loads, which disrupts the sedimentation process. However, the vortex in the cylindrical sedimentation tank helps organize the water flow into an orderly movement, reducing the degree of turbulence and allowing particles to settle in a relatively stable environment, thereby being able to withstand higher surface loads.
[0029] Furthermore, there are 3-5 mud-water separators 5. The mud-water separator 5 has a funnel-shaped structure with the larger opening facing downwards. The openings on the top and bottom sides of the mud-water separator 5 at the bottom are closed. This structural design allows sewage to flow upwards into the outlet pipe 4 between two adjacent mud-water separators 5. The mud and sand particles are intercepted on the surface of the mud-water separator 5 and finally gradually settle downwards to the bottom of the tank 1.
[0030] Specifically, a mud-water separator 5 is installed at the inlet end of the outlet pipe 4. In this embodiment, there are 3 mud-water separators 5. The mud wastewater flows upward into the outlet pipe 4 between two adjacent mud-water separators 5. The mud and sand particles are intercepted on the surface of the mud-water separator 5 and finally gradually settle downward into the mud hopper. Due to the existence of the inclined surface of the mud-water separator 5, the sludge particles only need to settle a small distance along the vertical direction of the inclined surface to be intercepted, which plays the role of blocking the effluent mud and sand. The inclined surface of the mud-water separator 5 divides the effluent flow into several thin layers. Under these circumstances, the Reynolds number of the water flow decreases, and the water flow is in a laminar flow state, which is more stable and less prone to turbulence. This makes it difficult for the sludge particles to be stirred up by the water flow, which is conducive to the sedimentation of the sludge particles. At the same time, it increases the sedimentation area and reduces the particle interception speed, thereby intercepting finer particles.
[0031] Furthermore, the extension line of the connection between the outlet side of the inlet pipe 3 and the inner wall of the tank 1 is tangent to the inner wall of the tank 1. This tangent design ensures that after the sewage enters the tank, it smoothly forms a swirling flow along the inner wall, avoiding direct impact of the water flow on the internal structure of the tank and ensuring the stability and continuity of the swirling flow.
[0032] Furthermore, the outlet pipe 4 has an L-shaped structure, and the central axis of the vertical part of the outlet pipe 4 and the central axis of the multiple mud-water separators 5 coincide with the central axis of the tank body 1. This layout ensures the uniform distribution and orderly flow of water inside the device, avoids the phenomenon of water flow deviation and short circuit, and further improves the efficiency of mud-water separation.
[0033] To achieve the self-cleaning function of the mud-water separator 5, such as Figure 3 As shown, an air compressor 6 is installed at the top of the tank 1, an aeration pipe 7 is installed at the air outlet of the air compressor 6, and multiple annular pipes 8 are installed at the bottom of the aeration pipe 7. Each annular pipe 8 has several micro air holes. Air is injected into the annular pipes 8 through the air compressor 6 and the aeration pipe 7, and the air is discharged through the micro air holes to clean the mud-water separator 5.
[0034] Furthermore, one end of the aeration pipe 7 extends into the tank 1 and passes through the mud-water separator 5 from top to bottom. Multiple annular pipes 8 are respectively attached to the inner wall of the mud-water separator 5, which can not only clean the mud-water separator 5, but also support the mud-water separator 5, thereby enhancing the overall stability of the device.
[0035] Furthermore, a drain pipe 9 is installed in the middle of the bottom of the tank 1 to periodically discharge impurities such as mud and sand that have settled at the bottom of the tank 1, ensuring the continuous and efficient operation of the device.
[0036] The workflow of this embodiment is as follows: Figure 4As shown, when muddy wastewater enters tank 1 through inlet pipe 3, because the outlet side of inlet pipe 3 is tangential to the inner wall of tank 1, the wastewater forms a stable vortex along the inner wall of tank 1 and moves downward in a spiral shape. During this process, the mud and sand particles in the wastewater have more time to settle. As the wastewater flows downward, it reaches the mud-water separator 5 area. The mud-water separator 5 is funnel-shaped with the larger opening facing downward, and gaps are formed between adjacent mud-water separators 5. The wastewater flows upward through these gaps into outlet pipe 4. During this process, the mud and sand particles are intercepted by the surface of the mud-water separator 5 and gradually settle downward to the bottom of tank 1. The inclined surface of separator 5 divides the water flow into a thin layer, and the water flow is in a laminar flow state, which further promotes the sedimentation of mud and sand particles. After the device has been running for a period of time, a certain amount of mud and sand and other impurities will be attached to the surface of mud and water separator 5, affecting the separation effect. At this time, the air compressor 6 is started. The air compressor 6 delivers air to the annular pipe 8 through the aeration pipe 7. The micro air holes on the annular pipe 8 will discharge air to clean mud and water separator 5. The mud and sand and other impurities settled at the bottom of tank 1 can be discharged periodically through the sewage pipe 9 in the middle of the bottom of tank 1. The operator can set a reasonable sewage discharge time interval according to the actual situation to ensure the normal operation of the device.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
