Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and more specifically, to a solid waste sludge dehydration treatment device for water conservancy construction. Background Art

[0002] Sludge is an extremely complex heterogeneous substance containing inorganic particles, organic substances, microorganisms, colloids, etc., and is one of the main products after water sedimentation and sewage treatment. Since the water content of sludge is high (about 80 - 99%), sludge needs to be dehydrated before it can be disposed of harmlessly such as landfilled or incinerated.

[0003] In the process of sludge dehydration treatment, the reuse equipment for primary sedimentation tank sludge usually relies on means such as sedimentation separation, chemical flocculation, and filtration to extract the sludge and put it back into use. However, the current existing solid waste sludge dehydration treatment devices are still relatively traditional in sedimentation separation, taking a long time and having low sedimentation efficiency. As one of the key factors affecting sedimentation efficiency, if the sedimentation area is not reasonably increased, the effective volume of the sedimentation tank may be difficult to carry all the particles that need to be sedimented. This will not only cause the residence time of the particles in the tank to be too short to fully sediment, but also once the particles are disturbed by the water flow during sedimentation, they may re - suspend, thereby increasing the suspended solid content in the effluent. In addition, the lack of sedimentation area and the lack of effective particle collision and adsorption mechanisms will further exacerbate the phenomenon of particle re - suspension, thus having an adverse impact on the sedimentation efficiency and effluent quality when the sludge is reused. In view of this, we propose a solid waste sludge dehydration treatment device for water conservancy construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a solid waste sludge dehydration treatment device for water conservancy construction to solve the technical problem that the reuse equipment for primary sedimentation tank sludge of the existing sludge dehydration treatment device is difficult to expand on the basis of the existing sedimentation tank and is difficult to specifically improve the water flow conditions, thereby restricting the sedimentation efficiency of the sludge and the effluent quality.

[0023] The spiral blades and the positioning block are both arranged in the second conduit, and the support frame is fixedly connected to one side of the flow guide shell.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By designing the transmission assembly, the liquid inlet assembly and the pressure assembly, when the liquid enters the liquid inlet assembly along the first conduit, it will squeeze the internal components thereof, so that the liquid is blocked, and then flows into the flow-through assembly along the sealing sleeve. Since the liquid is discharged in a spiral shape with a relatively large pressure in the flow-through assembly, the continuous liquid discharge will increase the weight above the bottom plate. After the bottom plate is pressed, it will squeeze the pressure assembly, discharge the gas into the power assembly, and push the sedimentation plate to flip along the rotating shaft. The liquid discharged from the first conduit and the second conduit directly impacts the sedimentation plate, which can buffer the impact force of the liquid entering the sedimentation tank. The setting of the sedimentation plate not only increases the sedimentation area inside the sedimentation tank, but also adopts the method of mixing the return sludge with the influent water, which can significantly improve the sedimentation speed and collision frequency of the particles, thereby improving the sedimentation efficiency. This enables the sedimentation tank to treat more wastewater in a shorter time, improves the treatment capacity of the entire treatment system. At the same time, by improving the collision and adsorption efficiency of the particles, more suspended solids and dissolved organic matter can be removed, significantly improving the effluent quality, helping to reduce the load of the subsequent treatment unit and lowering the overall treatment cost. In addition, the sedimentation plate buffers the impact force of the liquid falling, reduces the disturbance of the water flow to the sedimentation particles, and reduces the risk of particle resuspension, which is beneficial to maintaining the cleanliness and stability of the sedimentation tank and prolonging its service life.

[0026] 2. The present invention also designs a liquid inlet component and a circulation component. When the liquid is discharged into the liquid inlet housing along the first conduit, it will quickly enter the conical hole through the first through hole and squeeze the sealing ball, causing the sealing ball to slide within the conical hole. When the sealing ball contacts the limiting piece, a large amount of liquid will discharge along the gap between the sealing ball and the limiting piece and the diversion hole, pushing the sealing ball and reducing the liquid discharge space, which can effectively increase the pressure during liquid discharge. After the liquid enters the diversion housing from the liquid inlet housing, it will flow along the diversion groove within the diversion housing and discharge. At the same time, the liquid discharged along the first conduit will contact the spiral blade, squeezing the spiral blade and causing the mounting shaft and the support frame to be in a rotating state. At this time, the support frame drives the diversion housing to rotate, causing the liquid discharged from the diversion housing to be discharged in a spiral pressurized state and collide with the liquid discharged from the second conduit. Through this accelerated collision method, the particles can contact and aggregate with each other to form larger particle clusters, making them easier to remove. During the actual auxiliary precipitation process, the accelerated collision can also enable the medicament to more fully contact the particles in the sewage, thereby improving the utilization rate and effect of the medicament.

[0027] 3. The present invention also designs a power component and a pressure component. When the liquid is initially discharged, the liquid impacts the bottom plate, and the bottom plate will move downward to buffer the pressure of the liquid falling. As the liquid continues to be discharged, the bottom plate will squeeze the push rod downward, squeezing the gas within the sealing cylinder into the exhaust pipes on both sides. The gas is injected into the sliding sleeve through the exhaust pipes, thereby pushing the sliding rod to extend along the sliding sleeve, and further pushing the precipitation plate to flip along the rotating shaft. On the one hand, during the initial liquid discharge stage, the bottom plate buffers the impact force of the liquid falling by means of the elastic force of the spring; during the subsequent discharge process, the bottom plate moves to the bottommost position. At this time, the precipitation plate can provide buffering for the liquid falling, and buffering the liquid falling can slow down the water flow speed and reduce the disturbance of the water flow to the precipitated particles, which helps the particles to stably settle in the sedimentation tank and prevents the particles from resuspending due to the water flow disturbance. On the other hand, the design of the precipitation plate increases the sedimentable area of the sewage in the sedimentation tank, enabling more particles to find a "landing point" for sedimentation during the sedimentation process, thereby improving the sedimentation efficiency of the particles.

[0047] As Figures 1 to 9 shown, a solid waste sludge dehydration treatment device for water conservancy construction related to the present invention includes a sedimentation tank 101 and a second conduit 306, and further includes,

[0048] The precipitation mechanism 1 includes a sedimentation tank 101, four sealed bearings 102 arranged in the sedimentation tank 101, a rotating shaft 103 connected to the sealed bearings 102, a sedimentation plate 104, and a power assembly 105. Among them, the sedimentation plate 104 is connected to the rotating shaft 103, the power assembly 105 is connected to one side of the sedimentation plate 104, and the power assembly 105 is arranged outside the sedimentation tank 101; and, the adjustment mechanism 2 includes a bottom plate 201 and a pressure assembly 202. Among them, the bottom plate 201 is located inside the sedimentation tank 101, and the pressure assembly 202 is located below the bottom plate 201;And, a control mechanism 3, including four flow components 301, four sealing sleeves 302 arranged outside the four flow components 301, a liquid inlet component 303, a transmission component 304, a first conduit 305, and a second conduit 306 located inside the sealing sleeves 302. Among them, the first conduit 305 is connected to the liquid inlet component 303, the transmission component 304 is located inside the first conduit 305, and the first conduit 305 is arranged inside the flow component 301 and the liquid inlet component 303. When the liquid enters the liquid inlet component 303 along the first conduit 305, it will squeeze the internal components of the liquid inlet component 303, so that the liquid is blocked and enters the flow component 301 along the sealing sleeve 302. At this time, the water flow pressure increases and is discharged into the sedimentation tank 101 along the flow component 301. At the same time, since a large amount of liquid is directly discharged into the sedimentation tank 101 along the second conduit 306, the liquid will squeeze the transmission component 304 when flowing through the second conduit 306. While the transmission component 304 rotates, it synchronously drives the flow component 301 to rotate. At this time, due to the relatively large liquid discharge pressure and spiral discharge along the flow component 301, the outer liquid will collide and squeeze with the liquid discharged from the second conduit 306. The large particles and colloid substances in the sludge serve as coagulation cores, which can adsorb and wrap the small particles and dissolved organic matters in the influent water to form larger flocs. And the continuous liquid discharge will also increase the weight above the bottom plate 201, so that the gas is discharged into the power component 105 by squeezing the pressure component 202 through the bottom plate 201 and the sedimentation plate 104 is pushed to flip along the rotating shaft 103. The liquids discharged from the first conduit 305 and the second conduit 306 will directly impact the sedimentation plate 104, thereby buffering the impact force of the liquid discharged into the sedimentation tank 101. And the setting of the sedimentation plate 104 can increase the sedimentable area inside the sedimentation tank 101. Increasing the sedimentation area and adopting the method of mixing the return sludge with the influent water can significantly improve the sedimentation speed and collision frequency of the particles, thereby improving the sedimentation efficiency. This enables the sedimentation tank 101 to treat more wastewater in a shorter time, improving the treatment capacity of the entire treatment system. At the same time, by improving the collision and adsorption efficiency of the particles, more suspended solids and dissolved organic matters are removed, and the effluent water quality is significantly improved. This helps to reduce the load of the subsequent treatment unit and lower the overall treatment cost. And by buffering the impact force of the liquid falling through the sedimentation plate 104, the disturbance of the water flow to the sedimented particles is reduced, and the risk of particle resuspension is lowered. This helps to keep the sedimentation tank 101 clean and stable and extend its service life;

[0049] In an embodiment of the present invention, two sealing bearings 102 are clamped on both sides of the inner wall of the sedimentation tank 101. The two sealing bearings 102 corresponding in position are connected to both ends of the same rotating shaft 103. The rotating shaft 103 is sleeved in the sealing bearing 102, and the outer wall of the rotating shaft 103 is fixedly connected to the sedimentation plate 104. The two sedimentation plates 104 are respectively fixedly connected to the two power assemblies 105, and the two power assemblies 105 are respectively arranged on both sides of the sedimentation tank 101. An outlet is arranged on one side of the sedimentation tank 101. The power assembly 105 includes a mounting block 1051. The lower part of the mounting block 1051 communicates with the upper part of the sliding sleeve 1052. A sliding rod 1053 is slidably connected in the sliding sleeve 1052. The inner wall of the sliding sleeve 1052 and the outer wall of the sliding rod 1053 are both sealed. Both the sliding sleeve 1052 and the sliding rod 1053 are arc-shaped. The other end of the sliding rod 1053 passes through the sedimentation tank 101 and is fixedly connected to one side of the sedimentation plate 104. One side of the mounting block 1051 is fixedly connected to the corresponding side of the sedimentation tank 101. By designing the liquid inlet assembly 303 and the flow-through assembly 301, when the liquid is discharged into the liquid inlet housing 3031 along the first conduit 305, the liquid will quickly enter the conical hole 3034 through the first through hole 3033 and squeeze the sealing ball 3038, causing the sealing ball 3038 to slide in the conical hole 3034. When the sealing ball 3038 contacts the limiting piece 3036, a large amount of liquid will be discharged along the gap between the sealing ball 3038 and the limiting piece 3036 and the diversion hole 3037. Pushing the sealing ball 3038 and reducing the space for liquid discharge can effectively increase the pressure during liquid discharge. When the liquid enters the diversion housing 3011 along the liquid inlet housing 3031, it will flow along the diversion groove 3014 in the diversion housing 3011 and be discharged. The liquid discharged along the first conduit 305 will contact the spiral blade 3044 and thus squeeze the spiral blade 3044, causing the mounting shaft 3042 and the support frame 3041 to be in a rotating state. At this time, the support frame 3041 will drive the diversion housing 3011 to rotate, so that the liquid discharged along the diversion housing 3011 will be discharged in a state of spiral pressurization and collide with the liquid discharged from the second conduit 306, enabling the device to accelerate the collision. These particles can contact and aggregate with each other to form larger particle clusters, making them easier to remove. Moreover, when adding actual auxiliary sedimentation, the accelerated collision can make the medicament contact the particles in the sewage more fully, thereby improving the utilization rate and effect of the medicament.

[0050] In an embodiment of the present invention, the lower part of the bottom plate 201 is fixedly connected to the upper part of the pressure assembly 202. The bottom plate 201 is slidably connected in the sedimentation tank 101, and the bottom plate 201 is attached to the inside of the sedimentation tank 101. The lower part of the pressure assembly 202 is fixedly connected to the bottom of the sedimentation tank 101. The pressure assembly 202 is respectively connected to two sliding sleeves 1052 through two mounting blocks 1051. The pressure assembly 202 includes a sealing cylinder 2021. A push rod 2022 is slidably connected in the sealing cylinder 2021. The bottom end of the push rod 2022 is fixedly connected to the upper part of the piston plate 2023. A spring 2024 is fixedly connected to the lower part of the piston plate 2023. The bottom end of the spring 2024 is tightly welded to the lower part of the inner wall of the sealing cylinder 2021. Two exhaust pipes 2025 are fixedly connected to the outside of the sealing cylinder 2021. The lower part of the sealing cylinder 2021 is fixedly connected to the bottom end of the sedimentation tank 101. The top end of the push rod 2022 is fixedly connected to the lower part of the bottom plate 201. The two exhaust pipes 2025 are respectively connected to the two sliding sleeves 1052 through the two mounting blocks 1051. By designing the power assembly 105 and the pressure assembly 202, when the liquid is initially discharged, the liquid will impact the bottom plate 201. At this time, the bottom plate 201 will move downward and buffer the pressure when the liquid falls. As the liquid continues to be discharged, the bottom plate 201 will squeeze the push rod 2022 to move downward and squeeze the gas in the sealing cylinder 2021 into the exhaust pipes 2025 on both sides, and inject it into the sliding sleeve 1052 through the exhaust pipes 2025, so as to push the sliding rod 1053 to overflow along the sliding sleeve 1052, thereby pushing the sedimentation plate 104 to flip along the rotating shaft 103. On the one hand, when initially discharging, the bottom plate 201 will buffer the impact force of the liquid falling through the elastic force of the spring 2024. During the subsequent discharging process, the bottom plate 201 moves to the bottommost part, and the sedimentation plate 104 will provide buffering for the falling of the liquid. Buffering the falling of the liquid can slow down the water flow speed and reduce the disturbance of the water flow to the sedimentation particles. This helps the particles to settle stably in the sedimentation tank 101 and avoid the particles from resuspending due to the water flow disturbance. On the other hand, the design of the sedimentation plate 104 will also increase the sedimentable area in the sewage in the sedimentation tank 101, which helps more particles to find a "landing point" for sedimentation during the sedimentation process, thereby improving the sedimentation efficiency of the particles.

[0051] As another embodiment of the present invention, the outer wall of the circulation component 301 is clamped with the sealing sleeve 302. The circulation component 301 is communicated with the liquid inlet component 303 through the sealing sleeve 302. The sealing sleeve 302 is clamped outside the liquid inlet component 303. The second conduit 306 is located inside the diversion component and the liquid inlet component 303. The other end of the liquid inlet component 303 is communicated with the first conduit 305. The transmission component 304 is located inside the second conduit 306. The transmission component 304 is fixedly connected to one side of the circulation component 301. The sealing sleeve 302 is clamped on one side of the inner wall of the sedimentation tank 101. The second conduit 306 passes through the sedimentation tank 101 and is located inside the sedimentation tank 101. The circulation component 301 includes a diversion shell 3011. A first clamping groove 3012 is formed outside the diversion shell 3011. The first clamping groove 3012 is annular. A docking ring 3013 is fixedly connected to one side of the diversion shell 3011. The docking ring 3013 is communicated with the diversion shell 3011. A plurality of diversion grooves 3014 are formed inside the diversion shell 3011. And the plurality of diversion grooves 3014 are all spiral diversion grooves. The diversion shell 3011 is connected to the sealing sleeve 302 through the first clamping groove 3012. The sealing sleeve 302 is clamped inside the first clamping groove 3012. The diversion shell 3011 is communicated with the liquid inlet component 303 through the sealing sleeve 302. By designing the conical hole 3034, when the liquid initially enters the first through hole 3033, it is difficult to discharge, so as to squeeze the sealing ball 3038 to flow into the conical hole 3034. And in the subsequent discharge process, the liquid will discharge along the gap between the sealing ball 3038 and the conical hole 3034, thereby increasing the pressure during liquid discharge due to the collision with the sewage.

[0052] As another embodiment of the present invention, the liquid inlet assembly 303 includes a liquid inlet housing 3031. A second card slot 3032 is formed outside the liquid inlet housing 3031. A plurality of first through holes 3033 are formed on the other side of the liquid inlet housing 3031. The plurality of first through holes 3033 are respectively communicated with a plurality of tapered holes 3034. The plurality of tapered holes 3034 are respectively communicated with a plurality of second through holes 3035. The plurality of first through holes 3033, tapered holes 3034 and second through holes 3035 are all arranged obliquely. The diameter of the first through hole 3033 is smaller than that of the second through hole 3035. A plurality of limiting pieces 3036 are fixedly connected to the plurality of second through holes 3035. A plurality of diversion holes 3037 are formed on one side of the limiting piece 3036. A sealing ball 3038 is arranged in the tapered hole 3034. The diameter of the sealing ball 3038 is larger than that of the first through hole 3033 and smaller than that of the second through hole 3035. The liquid inlet housing 3031 is connected to the sealing sleeve 302 through the second card slot 3032. The other side of the liquid inlet housing 3031 is communicated with the first conduit 305. The transmission assembly 304 includes a support frame 3041. One side of the support frame 3041 is fixedly connected to the mounting shaft 3042. A positioning block 3043 is fixedly connected to the outside of the mounting shaft 3042. The positioning block 3043 is a tapered block. The outer wall of the positioning block 3043 is fixedly connected to a plurality of spiral blades 3044. The plurality of spiral blades 3044 are all bent. The spiral blades 3044 and the positioning block 3043 are both arranged in the second conduit 306. The support frame 3041 is fixedly connected to one side of the diversion housing 3011. When the sealing ball 3038 contacts the limiting piece 3036, a large amount of liquid will be discharged along the gap between the sealing ball 3038 and the limiting piece 3036 and the diversion holes 3037. Pushing the sealing ball 3038 and reducing the liquid discharge space can effectively increase the pressure during liquid discharge, so that the liquid enters the diversion housing 3011 at a faster speed and is discharged along the diversion housing 3011, ensuring that the liquid discharged from the first conduit 305 can contact and impact the liquid discharged from the second conduit 306.

[0053] Working principle: This embodiment provides a solid waste sludge dewatering treatment device for water conservancy construction. During use, the first conduit 305 and the second conduit 306 are respectively connected to two drainage ports. After the connection is completed, water can be injected for precipitation, so that a large amount of sewage can be injected into the sedimentation tank 101 for sedimentation treatment;

[0054] When the liquid enters the liquid inlet assembly 303 along the first conduit 305, it will squeeze the internal components of the liquid inlet assembly 303. As a result, the liquid is blocked and enters the circulation assembly 301 along the sealing sleeve 302. At this time, the water flow pressure increases, and the liquid is discharged into the sedimentation tank 101 along the circulation assembly 301. Meanwhile, a large amount of liquid is directly discharged into the sedimentation tank 101 along the second conduit 306. When the liquid flows through the second conduit 306, it will squeeze the transmission assembly 304. While the transmission assembly 304 rotates, it drives the circulation assembly 301 to rotate synchronously. Since the liquid discharge pressure in the circulation assembly 301 is relatively large and the liquid is discharged in a spiral shape, the outer liquid will collide and squeeze with the liquid discharged from the second conduit 306. The large particles and colloidal substances in the sludge serve as coagulation cores, which can adsorb and wrap the small particles and dissolved organic matter in the influent water to form larger flocs. The continuous liquid discharge will increase the weight above the bottom plate 201. After being pressed, the bottom plate 201 will squeeze the pressure assembly 202 to discharge the gas into the power assembly 105, pushing the sedimentation plate 104 to flip along the rotating shaft 103. The liquid discharged from the first conduit 305 and the second conduit 306 directly impacts the sedimentation plate 104, thereby buffering the impact force of the liquid entering the sedimentation tank 101. In addition, the setting of the sedimentation plate 104 increases the sedimentation area inside the sedimentation tank 101;

[0055] When the liquid is discharged into the liquid inlet housing 3031 along the first conduit 305, it will quickly enter the tapered hole 3034 through the first through hole 3033 and squeeze the sealing ball 3038, causing the sealing ball 3038 to slide in the tapered hole 3034. When the sealing ball 3038 contacts the limiting piece 3036, a large amount of liquid will discharge along the gap between the sealing ball 3038 and the limiting piece 3036 and the diversion hole 3037, pushing the sealing ball 3038 and reducing the liquid discharge space, which can effectively increase the pressure during liquid discharge. After the liquid enters the diversion housing 3011 from the liquid inlet housing 3031, it will flow and discharge along the diversion groove 3014 in the diversion housing 3011. At the same time, the liquid discharged along the first conduit 305 will contact the spiral blade 3044 and squeeze the spiral blade 3044, causing the mounting shaft 3042 and the support frame 3041 to be in a rotating state. At this time, the support frame 3041 drives the diversion housing 3011 to rotate, making the liquid discharged from the diversion housing 3011 be discharged in a spiral pressurized state and collide with the liquid discharged from the second conduit 306;

[0056] When the liquid is initially discharged, it will impact the bottom plate 201. At this time, the bottom plate 201 moves downward to buffer the pressure when the liquid falls. As the liquid continues to be discharged, the bottom plate 201 will squeeze the push rod 2022 to move downward, squeezing the gas in the sealing cylinder 2021 into the exhaust pipes 2025 on both sides. The gas then enters the sliding sleeve 1052 through the exhaust pipes 2025, thereby pushing the sliding rod 1053 to move along the sliding sleeve 1052, and further pushing the sedimentation plate 104 to flip along the rotating shaft 103.
