Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sludge treatment equipment, and in particular to a treatment device and a treatment method for river sludge. Background Art
[0002] River sludge refers to sediment that accumulates at the bottom of rivers over long periods of time. It is typically composed of silt, organic matter, heavy metals, microorganisms, plant debris, and pollutants. It is a major source of water pollution and can pose a threat to the ecological environment and human health if not properly handled.
[0003] Dredgers and suction pumps are used to remove river sludge, which is then processed in a decanter centrifuge. The decanter centrifuge is a continuously operated device widely used for solid-liquid separation. Its operating principle is based on the synergistic effect of centrifugal sedimentation and screw conveying, achieving continuous solid-liquid separation through the centrifugal force generated by high-speed rotation.
[0004] Decanter centrifuges include: Drum: A combination of horizontal cylinder and cone, divided into sedimentation section (cylindrical section) and dewatering section (conical section); Screw conveyor: coaxially nested in the drum, maintaining a small speed difference with the drum; Differential system: Dual motors are independently driven, and the differential speed is precisely controlled by the inverter; Drive system: main motor, auxiliary motor, bearing group, differential, etc.; Feed and discharge system: feed pipe, liquid phase outlet and solid phase outlet; Housing and shock absorption system: double-layer housing and shock absorption base; Auxiliary systems: lubrication system, control system (PLC+HMI: real-time monitoring of speed, differential speed, temperature, vibration and other parameters).
[0005] The slurry is fed into the screw conveyor through the slurry delivery pipe. The slurry rotates and is thrown out from the opening on the screw conveyor's shaft. After solid-liquid separation, the sediment is discharged from the solid phase outlet, and the water is discharged from the liquid phase outlet. However, if the slurry is fed directly from the delivery pipe, larger solid mixtures may not be thrown out smoothly from the screw conveyor's shaft opening after being output from the delivery pipe. They need to rebound and collide before being thrown out, which will conflict with the subsequently thrown slurry.
[0006] In view of this, we propose a treatment device and a treatment method for river sludge. Summary of the Invention

This solves the problem that for larger solid mixtures, when they are output from the conveying pipe and thrown out, they may not be thrown out smoothly from the opening on the shaft of the screw conveyor, and need to rebound and collide to decompose before being thrown out, which will conflict with the subsequently thrown out mud liquid.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figures 1 to 13 The present invention provides an embodiment: a treatment device for river sludge, including an auger arranged in a rotary drum 100, the auger including a connecting shaft 200 and a spiral blade 300, and also including a connecting pipe 400, the inlet end of the connecting pipe 400 is connected to an external pipeline for conveying mud liquid, the connecting pipe 400 extends into the inner cavity of the connecting shaft 200, and the extending end of the connecting pipe 400 is sleeved with a connecting ring 500, and a bulk material structure 600 is provided on one side of the connecting ring 500.
[0025] The bulk material structure 600 includes an outer sleeve 601 and an inner sleeve 602 . The outer sleeve 601 is fixedly arranged on one side of the connecting ring 500 , and the inner sleeve 602 is arranged inside the outer sleeve 601 . The inner cavity of the inner sleeve 602 is provided with a breaking up component 605 .
[0026] The breaking up component 605 includes a rubber strip 6051, and a plurality of rubber strips 6051 are fixedly arranged in an annular array on the inner cavity wall of the inner tube sleeve 602. There is a space between the two rubber strips 6051. A plurality of connecting blocks 6052 are movably arranged between the two rubber strips 6051. The plurality of connecting blocks 6052 are distributed along the space between the two rubber strips 6051. The two sides of the connecting block 6052 are respectively in contact with the side edges of two adjacent rubber strips 6051. The contact surface between the side edges of the connecting block 6052 and the side edges of the rubber strip 6051 is flat. The connecting block 6052 is movable along the two rubber strips 6051. The side edges of the connecting block 6052 and the side edges of the rubber strip 6051 are in contact with each other. Maintain contact state; a rubber sheet 6055 is fixedly arranged between the two connecting blocks 6052, and a groove 60551 is provided on the side of the rubber sheet 6055 facing away from the fluid contact. The rubber sheet 6055 blocks the space between the two connecting blocks 6052, and when the two connecting blocks 6052 are squeezed, a height difference is generated, and the rubber sheet 6055 is pulled. When the rubber sheet 6055 bends, it bends more smoothly through the groove 60551; a spring piece A6053 is provided between the side of the connecting block 6052 relative to the inner cavity wall of the inner tube sleeve 602 and the inner cavity wall of the inner tube sleeve 602. The spring piece A6053 is arc-shaped and is in an extruded state. The inlet diameter of the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055 is larger than the outlet diameter of the connecting pipe 400. The slurry fluid transported through the connecting pipe 400 directly enters the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055. The rubber strips 6051 and the rubber sheets 6055 are both made of corrosion-resistant rubber material.
[0027] The present invention provides a rubber strip 6051, a connecting block 6052, a spring piece A6053, a contact block 6054, a rubber sheet 6055 and a limit strip 6057. The connection block 6052 and the contact block 6054 transfer kinetic energy to the particle aggregates in the slurry after being squeezed, thereby dispersing the particle aggregates and facilitating the slurry to be thrown out from the opening on the shaft of the screw conveyor. This solves the problem that larger solid mixtures may not be able to be thrown out smoothly from the opening on the shaft of the screw conveyor after being output from the conveying pipe, and need to rebound and collide to decompose before being thrown out, which will conflict with the subsequently thrown out mud.
[0028] See also Figure 9 and Figure 10 The inner ends of both sides of the rubber strip 6051 are respectively fixed with limit strips 6057, and the limit strips 6057 are in contact and limited cooperation with the end of the connecting block 6052 which is away from the inner cavity wall of the inner tube sleeve 602.
[0029] The present invention provides the limiting strip 6057 , so that when the spring piece A 6053 is in a squeezed state, the connecting block 6052 is limited by the limiting strip 6057 , so that the connecting block 6052 is in a state of being pushed by the spring piece A 6053 .
[0030] See also Figure 7 A contact block 6054 is fixedly mounted on the side of the connecting block 6052 facing away from the inner wall of the inner tube sleeve 602. The flow-guiding side of the contact block 6054 is curved, with the curvature of the contact block 6054 oriented in the direction of the fluid flow. As the slurry passes through the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055, the slurry flows smoothly along the flow-guiding side of the contact block 6054.
[0031] See also Figure 6 and Figure 7 In one embodiment of the present invention, a device for treating river sludge is provided. A disintegration assembly 605 further includes an end ring plate 603, which is fixedly mounted on the outlet end of an inner pipe sleeve 602. A threaded sleeve 604 is fixedly mounted on one side of the end ring plate 603 and threadedly connected to the outlet end of an outer pipe sleeve 601. The threaded sleeve 604 is detachable from the outer pipe sleeve 601, allowing the inner pipe sleeve 602 and disintegration assembly 605 to be removed from the outer pipe sleeve 601 for easy replacement.
[0032] See also Figure 7 and Figure 12 A curved spring piece B6056 is disposed between each pair of connecting blocks 6052. The inner diameter of the end ring plate 603 is larger than the outlet diameter of the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055. The connecting block 6052 at the inlet end of the inner sleeve 602 contacts the connecting ring 500, while the connecting block 6052 at the outlet end of the inner sleeve 602 contacts the end ring plate 603. The connecting blocks 6052 at both ends of the inner sleeve 602 cavity are restrained, allowing the slurry to flow through the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055, and the slurry is confined within the fluid cavity.
[0033] The present invention provides an outer sleeve 601, an inner sleeve 602, an end ring plate 603, a threaded sleeve 604 and a spring piece B6056. When the aging of the breaking up component 605 affects the throwing out of the mud liquid, the inner sleeve 602 and the breaking up component 605 can be pulled out from the outer sleeve 601 for easy replacement; the spring piece B6056 provides an auxiliary elastic force to reset the connecting block 6052, and the mud liquid is restricted to flow in the fluid cavity.
[0034] See also Figure 4 and Figure 5, an embodiment provided by the present invention: a treatment device for river sludge, also includes a rotating shaft 900, a fixing ring 700 is sleeved on the outlet end of the outer pipe sleeve 601, and a plurality of connecting rods 800 are fixedly arranged in an annular array on one side of the fixing ring 700, and a discharge space is formed between each two connecting rods 800, and the discharge space corresponds to the discharge hole on the connecting shaft 200, and a sealed bearing 1000 is fixedly provided in the inner cavity of the connecting shaft 200, and the inner sleeve of the sealed bearing 1000 is fixedly connected to the protruding section of the rotating shaft 900, and a plurality of insertion holes 901 are opened in an annular array on the docking side of the rotating shaft 900, and the plug column 801 fixedly provided at the end of the connecting rod 800 is plugged into and matched with the insertion hole 901. After the socket 901 is docked with the column 801, while the connecting pipe 400 rotates, the connecting ring 500, the bulk structure 600, the fixed ring 700, the connecting rod 800 and the rotating shaft 900 rotate synchronously to throw out the mud liquid. When replacing the bulk structure 600, the connecting pipe 400, the connecting ring 500, the bulk structure 600, the fixed ring 700 and the connecting rod 800 can be pulled out, the socket 901 is separated from the column 801, and the bulk structure 600 is taken out from the openings of multiple connecting rods 800.
[0035] The present invention provides a fixing ring 700, a connecting rod 800, a rotating shaft 900, a sealed bearing 1000, a column 801 and a socket 901. When in use, the fixing ring 700, the connecting rod 800 and the rotating shaft 900 rotate synchronously to throw out the mud liquid. When disassembling, the rotating shaft 900 can be separated to disassemble the bulk structure 600 from the space.
[0036] Sludge treatment method, the treatment steps are as follows: S1, slurry is pumped in from the connecting pipe 400; S2. The slurry passes through the bulk structure 600 and enters the fluid cavity formed by the multiple rubber strips 6051, the multiple connecting blocks 6052, and the multiple rubber sheets 6055. S3. When the slurry passes through the fluid cavity, the particle aggregates in the slurry move irregularly under the push of the water flow and collide with the contact block 6054. After being subjected to force, the contact block 6054 pushes the connecting block 6052. The connecting block 6052 moves along the space between two adjacent rubber strips 6051. During the movement, the connecting block 6052 contacts the rubber strip 6051, and the spring piece A 6053 is further squeezed by the force. The spring piece B 6056 also undergoes a recoverable deformation. The rubber piece 6055 is pulled. The elastic force of the spring piece A 6053 and the spring piece B 6056 pushes the connecting block 6052 and the contact block 6054 to reset, thereby applying force to the corresponding particle aggregates, and the particle aggregates are decomposed after the collision. S4. After multiple collisions, the particle aggregates decompose and flow out of the fluid cavity along with the mud liquid. The distributor formed by the fixed ring 700, the connecting rod 800 and the rotating shaft 900 rotates to throw out the mud liquid, and then the mud liquid is thrown out from the opening on the shaft of the screw conveyor into the drum 100. After solid-liquid separation, the mud and sand are discharged from the solid phase outlet and the water is discharged from the liquid phase outlet.
[0037] Working principle: The mud liquid is pumped in from the connecting pipe 400, passes through the bulk structure 600, and enters the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052 and multiple rubber sheets 6055. When the mud liquid passes through the fluid cavity, the particle aggregates in the mud liquid move irregularly under the push of the water flow and collide with the contact block 6054. The instantaneous impact force causes the contact block 6054 to push the connecting block 6052 after being subjected to force. The connecting block 6052 moves along the space between two adjacent rubber strips 6051. During the movement, the connecting block 6052 contacts the rubber strip 6051, and the spring A 6053 is further squeezed by the force, and the spring piece B6056 also undergoes a recoverable deformation. The rubber sheet 6055 is pulled, pushing the connecting block 6052 and the contact block 6054 to reset, thereby applying force to the corresponding particle aggregates. The particle aggregates are decomposed after multiple collisions, and the distributor formed by the fixing ring 700, the connecting rod 800 and the rotating shaft 900 rotates to throw out the mud liquid, and then the mud liquid is thrown out from the opening on the shaft of the screw conveyor into the drum 100. After the differential rotation of the drum 100 and the auger, the solid-liquid separation is carried out. After the solid-liquid separation, the mud and sand are discharged from the solid phase outlet and the water is discharged from the liquid phase outlet.

Through the elastic force of the spring piece A (6053) and the spring piece B (6056), the connecting block (6052) and the contact block (6054) are pushed to reset, thereby applying force to the corresponding particle aggregates. The particle aggregates are decomposed after the collision. S4. After multiple collisions, the particle aggregates decompose and flow out of the fluid cavity along with the mud liquid. The distributor formed by the fixed ring (700), the connecting rod (800) and the rotating shaft (900) rotates to throw out the mud liquid. Then the mud liquid is thrown out from the opening on the shaft of the screw conveyor into the drum (100). After the solid and liquid are separated, the mud and sand are discharged from the solid phase outlet and the water is discharged from the liquid phase outlet.
