[0014] A water pollution sludge dehydration device for water conservancy river regulation, using the above-mentioned water pollution sludge dehydration device for water conservancy river regulation, includes: Step 1: Convey the sewage into the device through the feed inlet, start the crushing mechanism, and the output end of the crushing mechanism rotates to crush the large-particle impurities in the sewage, realizing the primary treatment and crushing of the sewage. The staff rotates the adjustment box to adjust the discharge rate of the water sludge impurities. Step 2: The rotation of the crushing mechanism drives the rotation of the first transmission belt.

The rotation of the screw rod drives the large-particle impurities accumulated inside the adjustment box to be conveyed towards the discharge port. Step 3: The sludge and water flow into the water inlet of the separation cylinder through the fixed box. At this time, start the motor. Since the output end of the motor contacts the fixed frame, the output end of the motor rotates to drive the fixed frame to rotate. The rotation of the fixed frame drives the rotation of the centrifugal cylinder. At the same time, the sludge and water enter the inside of the centrifugal cylinder through the separation cylinder, and the rotation of the centrifugal cylinder uses centrifugal force to throw out the water accumulated inside. Step 4: The water is thrown out through the filter holes provided on the circumferential surface of the centrifugal cylinder, and the sludge continues to accumulate inside the centrifugal cylinder. The water flows out through the water outlet. Subsequently, the dehydrated sludge falls through the centrifugal cylinder and then is pressure-filtered by the pressure filter for the dry sludge accumulated inside the cake frame.

[0015] The present invention provides a water pollution sludge dehydration device for water conservancy river regulation and its usage method. It has the following beneficial effects: (1) The water pollution sludge dewatering device for water conservancy river regulation is fed into the equipment through the feed inlet. The crushing mechanism is started, and the output end of the crushing mechanism rotates to crush the large particle impurities in the sewage, achieving the primary treatment and crushing of the sewage, preventing the large particle impurities from blocking the equipment, ensuring the continuous and stable operation of the equipment, improving the uniformity of the sludge, facilitating subsequent dewatering treatment, reducing the manual cleaning frequency, and lowering the maintenance cost. The staff rotates the adjustment box to adjust the discharge rate of the water sludge impurities, ensuring that the sludge and impurities are discharged as required, avoiding mixed pollution. The screw rod rotates to drive the large particle impurities accumulated inside the adjustment box to be transported towards the discharge port, realizing the screening of large particle impurities, sludge, and water, improving the purity of the sludge, facilitating subsequent resource utilization, reducing the wear of the impurities on the dewatering equipment, extending the service life of the equipment, thereby reducing the impact of the impurities on the dewatering effect and enhancing the dewatering efficiency.

[0016] (2) The water pollution sludge dewatering device for water conservancy river regulation is thrown out through the filter holes opened on the circumferential surface of the centrifugal cylinder, while the sludge continues to accumulate inside the centrifugal cylinder, realizing the centrifugal dewatering of the sludge, quickly separating the water in the sludge, significantly reducing the moisture content of the sludge, reducing the load in the subsequent pressure filtration stage, improving the overall treatment efficiency, facilitating the adaptability of the subsequent pressure filtration process to the horseshoe cake equipment. At the same time, the water flows out through the water outlet. Subsequently, the dewatered sludge falls through the centrifugal cylinder, and then the dry sludge accumulated inside the cake frame is pressure filtered by the pressure filter, realizing the compaction of the sludge, reducing the volume and water content of the sludge, improving the stacking efficiency of the sludge, further reducing the moisture content of the sludge, forming a dry and hard mud cake, facilitating transportation and disposal, and at the same time improving the stability of the sludge and reducing the risk of secondary pollution.

[0017] (3) The water pollution sludge dewatering device for water conservancy river regulation drives the stirring plate to rotate by the rotation of the rotating ring. At this time, the stirring plate rotates to stir and break up the sludge inside the centrifugal cylinder, improving the uniformity of the sludge. The stirring makes the sludge distribution more uniform, avoiding local accumulation, enhancing the effect of centrifugal dewatering, and the stirring prevents the sludge from caking during the centrifugation process, ensuring the fluidity of the sludge, facilitating subsequent treatment. At the same time, the stirring helps to treat highly viscous sludge and expands the applicable range of the equipment.

[0018] (4) For the water pollution sludge dewatering device used in water conservancy river regulation, as the stirring plate moves, it drives the rotating rod to move upward. As the rotating rod moves upward, it drives the sliding ring to move. At this time, as the sliding ring moves upward, it scrapes the sludge adhering to or blocking the filter holes inside the centrifuge cylinder, preventing the centrifuge cylinder from being blocked by sludge, thus affecting the screening effect and working efficiency of the centrifuge cylinder, reducing the corrosion and wear of the inner wall by the sludge, and extending the service life of the centrifuge cylinder. Thereby, it ensures the uniform distribution of centrifugal force, maintains the high-efficiency operation of the equipment. The knocking rod moves upward until it contacts the surface of the fixed disk and generates vibration. The vibration of the fixed disk is transmitted to the rotating shaft, realizing self-cleaning of the parts inside the centrifuge cylinder, preventing sludge from adhering or sticking to the surface of the components during long-term use, thus affecting their working efficiency, reducing the frequency of manual cleaning, lowering the maintenance cost, ensuring the continuous operation of the equipment, and avoiding shutdown caused by blockage.

[0019] (5) For the water pollution sludge dewatering device used in water conservancy river regulation, as the L-shaped plate moves, it drives the pressing plate to move downward. As the pressing plate moves downward, it compacts the dehydrated sludge, reducing the volume and water content of the sludge, improving the stacking efficiency of the sludge, further reducing the sludge moisture content, forming a dry and hard mud cake, which is convenient for transportation and disposal. At the same time, it improves the stability of the sludge, reduces the risk of secondary pollution, and the compacted sludge has a higher density, which is convenient for transportation and subsequent treatment. As the inclined block moves, it drives the arc plate to move. Under the action of the inclined block, the arc plate moves to push the sludge at the edge towards the middle, ensuring uniform pressure distribution during the pressure filtration process, avoiding incomplete dehydration caused by insufficient local pressure, making full use of the pressure filtration area, and enhancing the overall dehydration efficiency.

[0025] There is a first transmission belt connected between the crushing mechanism 61 and the screw rod 63. An outlet is provided on the surface of the adjustment box 3. The centrifugal cylinder 65 rotates through the surface of the main body 1. The output end of the motor 64 contacts the surface of the fixed frame 66. The sludge and water enter the interior of the centrifugal cylinder 65 through the separation cylinder 4. The centrifugal cylinder 65 rotates to throw out the water from the accumulated sludge and water inside by centrifugal force.

[0026] A water pollution sludge dewatering device for water conservancy river regulation, using a water pollution sludge dewatering device for water conservancy river regulation, includes: Step 1: Convey the sewage into the device through the feed inlet 51, and start the crushing mechanism 61. The output end of the crushing mechanism 61 rotates to crush the large-particle impurities in the sewage, realizing the primary treatment and crushing of the sewage. The staff rotates the adjustment box 3 to adjust the discharge rate of the water sludge impurities. Step 2: The rotation of the crushing mechanism 61 drives the rotation of the first transmission belt. At the same time, the rotation of the first transmission belt drives the screw rod 63 to rotate. The rotation of the screw rod 63 drives the large-particle impurities accumulated inside the adjustment box 3 to be conveyed towards the outlet. Step 3: The sludge and water flow into the water inlet of the separation cylinder 4 through the fixed box 2. At this time, start the motor 64. Since the output end of the motor 64 contacts the fixed frame 66, the output end of the motor 64 rotates to drive the fixed frame 66 to rotate. The rotation of the fixed frame 66 drives the centrifugal cylinder 65 to rotate. At the same time, the sludge and water enter the interior of the centrifugal cylinder 65 through the separation cylinder 4. The centrifugal cylinder 65 rotates to throw out the water from the accumulated sludge and water inside by centrifugal force. Step 4: The water is thrown out through the filter holes provided on the circumferential surface of the centrifugal cylinder 65, while the sludge continues to accumulate inside the centrifugal cylinder 65. The water flows out through the water outlet 52. Subsequently, the dehydrated sludge falls through the centrifugal cylinder 65, and then the dry sludge accumulated inside the cake frame 67 is filtered by a filter press. During the operation of this embodiment: Sewage is transported into the device through the feed port 51. The crushing mechanism 61 is started. The output end of the crushing mechanism 61 rotates to crush large particulate impurities in the sewage, achieving the primary treatment and crushing of the sewage, preventing large particulate impurities from clogging the device, ensuring the continuous and stable operation of the device, improving the uniformity of the sludge, facilitating subsequent dehydration treatment, reducing the manual cleaning frequency, and lowering the maintenance cost. The staff rotates the adjustment box 3 to adjust the discharge rate of water, sludge, and impurities, ensuring that the sludge and impurities are discharged as needed and avoiding mixed pollution. Subsequently, the rotation of the crushing mechanism 61 drives the rotation of the first conveyor belt. At the same time, the rotation of the first conveyor belt drives the rotation of the screw rod 63. The rotation of the screw rod 63 drives the large particulate impurities accumulated inside the adjustment box 3 to be transported towards the discharge port, realizing the screening of large particulate impurities, sludge, and water, improving the purity of the sludge, facilitating subsequent resource utilization, reducing the wear of the impurities on the dehydration equipment, extending the service life of the equipment, thereby reducing the impact of impurities on the dehydration effect and enhancing the dehydration efficiency. Subsequently, the sludge and water flow into the water inlet of the separation cylinder 4 through the fixed box 2. At this time, the motor 64 is started. Since the output end of the motor 64 contacts the fixed frame 66, the rotation of the output end of the motor 64 drives the rotation of the fixed frame 66. The rotation of the fixed frame 66 drives the rotation of the centrifugal cylinder 65. At the same time, the sludge and water enter the inside of the centrifugal cylinder 65 through the separation cylinder 4. The rotation of the centrifugal cylinder 65 uses centrifugal force to throw out the water accumulated inside the sludge and water. At this time, the water is thrown out through the filter holes formed on the circumferential surface of the centrifugal cylinder 65, while the sludge continues to accumulate inside the centrifugal cylinder 65, realizing the dewatering of the sludge by centrifugation, quickly separating the water in the sludge, significantly reducing the moisture content of the sludge, reducing the load in the subsequent pressure filtration stage, improving the overall treatment efficiency, facilitating the adaptability of the subsequent pressure filtration process to the horseshoe cake equipment. At the same time, the water flows out through the water outlet 52. Subsequently, the dehydrated sludge falls through the centrifugal cylinder 65. Then, the dry sludge accumulated inside the cake frame 67 is pressure-filtered by a filter press, realizing the compaction of the sludge, reducing the volume and water content of the sludge, improving the stacking efficiency of the sludge, further reducing the moisture content of the sludge, forming a dry and hard mud cake, facilitating transportation and disposal, and at the same time improving the stability of the sludge and reducing the risk of secondary pollution.

[0027] Please refer to Figures 1 - 7 , on the basis of the above embodiment, in another embodiment of the present invention, a stirring device for stirring the sludge is provided on the surface of the separation cylinder 4.

Stirring plates 74 are fixedly installed on the circumferential surface of the rotating ring 73. Rotating rods 75 are rotatably installed on the surfaces of the stirring plates 74. A sliding ring 76 is slidably installed on the inner wall of the centrifugal cylinder 65. A knocking rod 77 is fixedly installed on the surface of the rotating ring 73. The upward movement of the rotating ring 73 drives the movement of the knocking rod 77. At this time, the knocking rod 77 moves upward until it contacts the surface of the fixed disk 72 to generate vibration.

[0028] The rotating ring 73 is threadedly connected to the rotating shaft 71. The sliding ring 76 contacts the rotating rod 75. There is a second transmission belt for transmission connection between the rotating shaft 71 and the motor 64. The rotating shaft 71 is threadedly connected to the rotating ring 73. When the rotating shaft 71 rotates, it drives the rotating ring 73 to move upward.

[0029] The inclination angle of the stirring plate 74 is set as the inclination angle. The circumferential surface of the rotating shaft 71 is provided with a reciprocating thread groove. When the rotating shaft 71 rotates, it drives the rotating ring 73 to rotate. At the same time, when the rotating ring 73 rotates, it drives the stirring plate 74 to rotate.

[0030] The circumferential surface of the sliding ring 76 is provided with a compaction device for further compacting the dehydrated sludge. The compaction device includes an L-shaped plate 81. The L-shaped plate 81 is fixedly installed on the circumferential surface of the sliding ring 76. A closing plate 82 is fixedly installed on the surface of the L-shaped plate 81. A pressing plate 83 is fixedly installed at one end of the L-shaped plate 81 away from the sliding ring 76. An inclined plate 84 is fixedly installed on the surface of the L-shaped plate 81. An arc plate 85 is slidably installed on the surface of the main body 1. An inclined block 86 is fixedly installed on the surface of the arc plate 85. A telescopic elastic rod one 87 is fixedly installed on the surface of the sludge cake frame 67. A chassis 88 is slidably installed at the bottom of the main body 1. When the sludge is filter-pressed, the chassis 88 is pulled by an external force to move away from the discharge port until the limit on the sludge cake frame 67 is released. At this time, the processed sludge cake falls through the mud outlet. A telescopic elastic rod two 89 is fixedly installed at the bottom of the main body 1.

[0031] The closing plate 82 is slidably connected to the circumferential surface of the separation cylinder 4 and is also slidably connected to the circumferential surface of the centrifugal cylinder 65. The surface of the pressing plate 83 is provided with filter holes. The surface of the inclined plate 84 close to the inclined block 86 is set as the first inclined surface. The surface of the inclined block 86 close to the inclined plate 84 is set as the second inclined surface. The free end of the telescopic elastic rod one 87 is fixedly connected to the arc plate 85. When the inclined block 86 moves, it drives the arc plate 85 to move. Under the action of the inclined block 86, the arc plate 85 moves to push the sludge at the edge towards the middle. The free end of the telescopic elastic rod two 89 is fixedly connected to the chassis 88. The L-shaped plate 81 slidably penetrates through the surface of the main body 1. The surface of the chassis 88 is provided with a traction hole.

[0032] During the operation of this embodiment: When the second conveyor belt rotates under the action of the output end of the motor 64, it drives the rotation of the rotating shaft 71. The rotation of the rotating shaft 71 drives the rotation of the rotating ring 73. At the same time, the rotation of the rotating ring 73 drives the rotation of the stirring plate 74. At this time, the rotation of the stirring plate 74 stirs and breaks up the sludge inside the centrifuge cylinder 65, improving the uniformity of the sludge, making the sludge distribution more uniform, avoiding local accumulation, enhancing the centrifugal dehydration effect, and preventing the sludge from caking during centrifugation, ensuring the fluidity of the sludge, facilitating subsequent treatment. At the same time, stirring helps to handle highly viscous sludge, expanding the application range of the equipment. Since the rotating shaft 71 and the rotating ring 73 are connected by threads, the rotation of the rotating shaft 71 drives the rotating ring 73 to move upward. At this time, the movement of the rotating ring 73 drives the stirring plate 74 to move upward. At the same time, the movement of the stirring plate 74 drives the rotating rod 75 to move upward. The upward movement of the rotating rod 75 drives the sliding ring 76 to move. At this time, the upward movement of the sliding ring 76 scrapes off the sludge adhering to or blocking the filter holes inside the centrifuge cylinder 65, avoiding the influence of sludge blockage of the centrifuge cylinder 65 on the screening effect and working efficiency of the centrifuge cylinder 65, reducing the corrosion and wear of the inner wall by the sludge, and prolonging the service life of the centrifuge cylinder 65, thereby ensuring the uniform distribution of centrifugal force and maintaining the high-efficiency operation of the equipment. At the same time, the upward movement of the rotating ring 73 drives the knocking rod 77 to move. At this time, the upward movement of the knocking rod 77 until it contacts the surface of the fixed disk 72 generates vibration. The vibration of the fixed disk 72 transmits the vibration to the rotating shaft 71, realizing self-cleaning of the parts inside the centrifuge cylinder 65, avoiding the adhesion or bonding of sludge on the surface of the parts during long-term use, thereby affecting their working efficiency, reducing the frequency of manual cleaning, lowering the maintenance cost, ensuring the continuous operation of the equipment, and avoiding shutdown caused by blockage. When the sliding ring 76 moves under the action of the rotating shaft 71, it drives the L-shaped plate 81 to move. At the same time, the movement of the L-shaped plate 81 drives the pressing plate 83 to move downward. The downward movement of the pressing plate 83 compresses the dehydrated sludge, reducing the volume and water content of the sludge, improving the stacking efficiency of the sludge, further reducing the moisture content of the sludge, forming a dry and hard sludge cake, facilitating transportation and disposal. At the same time, it improves the stability of the sludge and reduces the risk of secondary pollution. Moreover, the compacted sludge has a higher density, facilitating transportation and subsequent treatment. At the same time, the downward movement of the L-shaped plate 81 drives the inclined plate 84 to move downward. The downward movement of the inclined plate 84 contacts and squeezes the inclined block 86 to move towards the centrifuge cylinder 65. At the same time, the movement of the inclined block 86 drives the arc plate 85 to move. The movement of the arc plate 85 under the action of the inclined block 86 pushes the sludge at the edge towards the middle, ensuring uniform pressure distribution during the pressure filtration process, avoiding incomplete dehydration caused by insufficient local pressure, making full use of the pressure filtration area, and enhancing the overall dehydration efficiency. When the sludge is pressure-filtered, an external force is used to pull the chassis 88 away from the discharge port until the limit on the sludge cake frame 67 is released. At this time, the processed sludge cake falls through the sludge outlet.
