Description

Technical Field

[0001] This invention relates to the field of sludge treatment equipment technology, specifically to a treatment device and method for river sludge. Background Technology

[0002] River sludge refers to sediment that accumulates at the bottom of rivers over a long period of time. It is typically composed of mud, sand, organic matter, heavy metals, microorganisms, plant debris, and pollutants. It is a significant source of water pollution, and improper treatment can pose a threat to the ecological environment and human health.

[0003] Dredgers and sludge pumps are used to remove sludge from river channels. The removed sludge is then processed using a horizontal screw centrifuge. The horizontal screw centrifuge is a widely used continuous operation device for solid-liquid separation. Its working 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] Horizontal decanter centrifuges include:

[0005] Rotary drum: a combination of a horizontal cylinder and a cone, divided into a settling section (cylinder) and a dewatering section (cone);

[0006] Screw conveyor: coaxially nested inside the drum, maintaining a slight speed difference with the drum;

[0007] Differential system: Dual motors drive independently, with differential speed precisely controlled by a frequency converter;

[0008] Drive system: main motor, auxiliary motor, bearing assembly, differential, etc.;

[0009] Feeding and discharging system: feed pipe, liquid phase outlet and solid phase outlet;

[0010] Housing and shock absorption system: double-layer housing and shock-absorbing base;

[0011] Auxiliary systems: lubrication system, control system (PLC+HMI: real-time monitoring of parameters such as speed, differential speed, temperature, and vibration).

[0012] The mud slurry is fed into the screw conveyor through the mud slurry delivery pipe. As it rotates, it is thrown out from the opening on the screw conveyor shaft. 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. However, when the mud slurry is directly fed into the pipe, larger solid mixtures may not be able to be smoothly thrown out from the screw conveyor shaft after exiting the pipe. They may need to rebound and decompose before being thrown out, which can cause interference with the subsequent discharge of mud slurry.

[0013] In view of this, we propose a treatment device and method for river sludge. Summary of the Invention

[0014] The purpose of this invention is to provide a treatment device and method for river sludge, so as to solve the problems mentioned in the background art.

[0015] To achieve the above objectives, the present invention provides the following technical solution: a device for treating river sludge, comprising an auger disposed inside a rotating drum, the auger comprising a connecting shaft and spiral blades, and further comprising a connecting pipe, the connecting pipe extending into the inner cavity of the connecting shaft, a connecting ring sleeved at the end of the connecting pipe extending into the shaft, and a material dispersing structure disposed on one side of the connecting ring;

[0016] The bulk material structure includes an outer sleeve and an inner sleeve. The outer sleeve is fixedly installed on one side of the connecting ring, and the inner sleeve is installed inside the outer sleeve. The inner cavity of the inner sleeve is provided with a dispersing component.

[0017] The dispersing component includes rubber strips, and multiple rubber strips are fixedly arranged in a ring array on the inner wall of the inner tube sleeve. Multiple connecting blocks are movably arranged between each pair of rubber strips, and rubber sheets are fixedly arranged between each pair of connecting blocks. A spring piece A is arranged between the side of the connecting block relative to the inner wall of the inner tube sleeve and the inner wall of the inner tube sleeve. The spring piece A is arc-shaped.

[0018] Preferably, the two sides of the connecting block respectively contact and engage with the sides of two adjacent rubber strips, and the contact surface between the side of the connecting block and the side of the rubber strip is a plane.

[0019] Preferably, limit strips are fixedly provided at the inner ends of both sides of the rubber strip, and the limit strips are in contact with and limited by the end of the connecting block on the side opposite to the inner wall of the inner tube sleeve.

[0020] Preferably, a contact block is fixedly provided on the side of the connecting block opposite to the inner wall of the inner tube sleeve, and the flow guiding side of the contact block is arc-shaped, with the arc of the flow guiding side of the contact block arranged along the fluid direction.

[0021] Preferably, the rubber sheet has a groove on the side facing away from the fluid contact.

[0022] Preferably, the inlet diameter of the fluid cavity formed by the plurality of rubber strips, the plurality of connecting blocks, and the plurality of rubber sheets is larger than the outlet diameter of the connecting pipe.

[0023] Preferably, the dispersing component further includes an end ring plate, which is fixedly disposed at the outlet end of the inner tube sleeve. A threaded sleeve is fixedly disposed on one side of the end ring plate, and the threaded sleeve is threadedly connected to the outlet end of the outer tube sleeve.

[0024] Preferably, a spring piece B is provided between each pair of connecting blocks. The spring piece B is arc-shaped. The inner ring diameter of the end ring plate is larger than the outlet diameter of the fluid cavity formed by the multiple rubber strips, multiple connecting blocks and multiple rubber pieces. The connecting block at the inlet end of the inner tube sleeve contacts the connecting ring, and the connecting block at the outlet end of the inner tube sleeve contacts the end ring plate.

[0025] Preferably, it also includes a rotating shaft, and a fixing ring is sleeved on the outlet end of the outer tube. Multiple connecting rods are fixedly arranged in a ring array on one side of the fixing ring, and a discharge space is formed between each pair of connecting rods. The discharge space corresponds to the discharge hole on the connecting shaft. A sealed bearing is fixedly arranged in the inner cavity of the connecting shaft. The inner bushing of the sealed bearing is fixedly connected to the protruding section of the rotating shaft. Multiple insertion holes are opened in a ring array on the mating side of the rotating shaft. The insertion post fixedly arranged at the end of the connecting rod is inserted into the insertion hole.

[0026] The sludge treatment method and steps are as follows:

[0027] S1. The mud slurry is pumped in through the connecting pipe;

[0028] S2. The mud slurry passes through the bulk structure and enters the fluid cavity formed by multiple rubber strips, multiple connecting blocks and multiple rubber sheets;

[0029] S3. When the mud slurry passes through the fluid cavity, the particle aggregates in the mud slurry move randomly under the impetus of the water flow and collide with the contact block. After being subjected to force, the contact block pushes the connecting block. The connecting block moves along the space between two adjacent rubber strips. During the movement, the connecting block contacts the rubber strips, the spring A is further squeezed by the force, and the spring B also undergoes a recoverable deformation. The rubber strip is pulled. Through the elastic force of the spring A and the spring B, the connecting block and the contact block are pushed to reset, thereby applying force to the corresponding particle aggregates. The particle aggregates decompose after collision.

[0030] S4. After multiple collisions, the particle aggregates decompose and flow out of the fluid cavity with the mud. The distributor formed by the fixed ring, connecting rod and rotating shaft rotates and throws the mud out. Then the mud is thrown out from the opening on the shaft of the screw conveyor and enters the drum. 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.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention, by setting up rubber strips, connecting blocks, spring A, contact blocks, rubber sheets, and limiting strips, has the advantage of transmitting kinetic energy through the resetting impact of the particle aggregates in the slurry after being squeezed by the connecting blocks and contact blocks, dispersing the particle aggregates, and helping the slurry to be thrown out from the opening on the shaft of the screw conveyor. It solves the problem that for larger solid mixtures, when thrown out from the conveying pipe, they may not be able to be thrown out smoothly from the opening on the shaft of the screw conveyor, and need to rebound and decompose before being thrown out, which will conflict with the subsequent throwing out of slurry.

[0033] 2. The present invention, by setting an outer sleeve, an inner sleeve, an end ring plate, a threaded sleeve and a spring piece B, has the advantages of allowing the inner sleeve and the dispersing component to be pulled out for easy replacement when the aging of the dispersing component affects the mud slurry discharge; the spring piece B provides auxiliary elastic force to reset the connecting block, and the mud slurry is restricted to flow within the fluid cavity.

[0034] 3. The present invention has the advantages of setting a fixed ring, connecting rod, rotating shaft, sealed bearing, insert post and insert hole, which allows the fixed ring, connecting rod and rotating shaft to rotate synchronously to throw out mud slurry during use, and the rotating shaft can be separated during disassembly to disassemble the bulk material structure from space.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figures 1 to 13 An embodiment of the present invention provides a device for treating river sludge, comprising an auger disposed within a rotating drum 100. The auger includes a connecting shaft 200 and spiral blades 300, and also includes a connecting pipe 400. The inlet end of the connecting pipe 400 is connected to an external pipe for conveying sludge. The connecting pipe 400 extends into the inner cavity of the connecting shaft 200, and a connecting ring 500 is sleeved on the end of the connecting pipe 400. A material distribution structure 600 is provided on one side of the connecting ring 500.

[0056] The bulk material structure 600 includes an outer sleeve 601 and an inner sleeve 602. The outer sleeve 601 is fixedly installed on one side of the connecting ring 500, and the inner sleeve 602 is installed inside the outer sleeve 601. The inner cavity of the inner sleeve 602 is provided with a dispersing component 605.

[0057] The dispersing component 605 includes rubber strips 6051. Multiple rubber strips 6051 are fixedly arranged in a ring array on the inner wall of the inner sleeve 602. Space is left between each pair of rubber strips 6051. Multiple connecting blocks 6052 are movably arranged between each pair of rubber strips 6051. The connecting blocks 6052 are distributed along the space between each pair of rubber strips 6051. Each side of a connecting block 6052 contacts and engages with the side of two adjacent rubber strips 6051. The contact surfaces between the sides of the connecting blocks 6052 and the sides of the rubber strips 6051 are planar. The connecting blocks 6052 move along the space between each pair of rubber strips 6051. Maintaining contact; a rubber sheet 6055 is fixedly installed between each pair of connecting blocks 6052. The side of the rubber sheet 6055 away from the fluid contact has a groove 60551. The rubber sheet 6055 blocks the space between the two connecting blocks 6052. 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 wall of the inner tube sleeve 602 and the inner wall of the inner tube sleeve 602. The spring piece A6053 is arc-shaped and is in a squeezed state. The inlet diameter of the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052, and multiple rubber sheets 6055 is larger than the outlet diameter of the connecting pipe 400. The slurry transported through the connecting pipe 400 directly enters the fluid cavity formed by the multiple rubber strips 6051, multiple connecting blocks 6052, and multiple rubber sheets 6055. Both the rubber strips 6051 and the rubber sheets 6055 are made of corrosion-resistant rubber material.

[0058] This invention, by setting up a rubber strip 6051, a connecting block 6052, a spring sheet A6053, a contact block 6054, a rubber sheet 6055, and a limiting strip 6057, has the advantage of transferring kinetic energy through the resetting impact of the particle aggregates in the slurry after being squeezed by the connecting block 6052 and the contact block 6054, dispersing the particle aggregates, and facilitating the slurry to be thrown out from the opening on the shaft of the screw conveyor. It solves the problem that for larger solid mixtures, when thrown out from the conveying pipe, they may not be able to be thrown out smoothly from the opening on the shaft of the screw conveyor, and need to rebound and decompose before being thrown out, which would conflict with the subsequent throwing out of slurry.

[0059] Please see Figure 9 and Figure 10 Limiting strips 6057 are fixedly installed on the inner ends of both sides of the rubber strip 6051. The limiting strips 6057 and the end of the connecting block 6052 opposite to the inner wall of the inner tube sleeve 602 are in contact and limited fit.

[0060] The present invention has the advantage that when the spring piece A6053 is in a compressed state, the connecting block 6052 is limited by the limiting strip 6057, so that the connecting block 6052 is in a state pushed by the spring piece A6053.

[0061] Please see Figure 7 A contact block 6054 is fixedly installed on the side of the connecting block 6052 opposite to the inner wall of the inner sleeve 602. The flow guiding side of the contact block 6054 is arc-shaped, and the arc of the flow guiding side of the contact block 6054 is arranged along the fluid direction. When the mud flows through the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052 and multiple rubber sheets 6055, the mud flows smoothly along the flow guiding side of the contact block 6054.

[0062] Please see Figure 6 and Figure 7 One embodiment of the present invention provides a device for treating river sludge. The dispersing component 605 further includes an end ring plate 603, which is fixedly disposed at the outlet end of the inner sleeve 602. A threaded sleeve 604 is fixedly disposed on one side of the end ring plate 603, and the threaded sleeve 604 is threadedly connected to the outlet end of the outer sleeve 601. The threaded sleeve 604 and the outer sleeve 601 are detachable, allowing the inner sleeve 602 and the dispersing component 605 to be pulled out from the outer sleeve 601 for easy replacement.

[0063] Please see Figure 7 and Figure 12 A spring piece B6056 is provided between each pair of connecting blocks 6052. The spring piece B6056 is arc-shaped. The inner ring diameter of the end ring plate 603 is larger than the outlet diameter of the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052, and multiple rubber sheets 6055. The connecting block 6052 at the inlet end of the inner tube sleeve 602 contacts the connecting ring 500, and the connecting block 6052 at the outlet end of the inner tube sleeve 602 contacts the end ring plate 603. The connecting blocks 6052 at both ends of the inner cavity of the inner tube sleeve 602 are limited, and the mud slurry passes through the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052, and multiple rubber sheets 6055, and the flow of the mud slurry is restricted within the fluid cavity.

[0064] The present invention, by setting an outer sleeve 601, an inner sleeve 602, an end ring plate 603, a threaded sleeve 604, and a spring piece B6056, has the advantages of allowing the inner sleeve 602 and the dispersing component 605 to be pulled out from the outer sleeve 601 for easy replacement when the dispersing component 605 ages and affects the mud slurry discharge; and the auxiliary elastic force of the spring piece B6056 to release the connecting block 6052 to reset, thus restricting the flow of mud slurry within the fluid cavity.

[0065] Please see Figure 4 and Figure 5An embodiment of the present invention provides a device for treating river sludge, which further includes a rotating shaft 900, a fixing ring 700 sleeved at the outlet end of an outer sleeve 601, a plurality of connecting rods 800 fixedly arranged in a ring array on one side of the fixing ring 700, a discharge space formed between each pair of connecting rods 800, the discharge space corresponding to the discharge hole on the connecting shaft 200, a sealing bearing 1000 fixedly arranged in the inner cavity of the connecting shaft 200, the inner bushing of the sealing bearing 1000 fixedly connected to the protruding section of the rotating shaft 900, a plurality of insertion holes 901 arranged in a ring array on the mating side of the rotating shaft 900, and insertion posts 801 fixedly arranged at the ends of the connecting rods 801 being inserted into and engaged with the insertion holes 901. After the insertion hole 901 is connected to the insertion post 801, the connecting pipe 400 rotates while the connecting ring 500, the bulk material structure 600, the fixing ring 700, the connecting rod 800, and the rotating shaft 900 rotate synchronously to throw out the mud. When replacing the bulk material structure 600, the connecting pipe 400, the connecting ring 500, the bulk material structure 600, the fixing ring 700, and the connecting rod 800 can be pulled out, the insertion hole 901 is separated from the insertion post 801, and the bulk material structure 600 can be taken out from the openings of the multiple connecting rods 800.

[0066] The present invention, by setting a fixing ring 700, a connecting rod 800, a rotating shaft 900, a sealed bearing 1000, a plug 801, and a plug hole 901, has the advantages that when in use, the fixing ring 700, the connecting rod 800, and the rotating shaft 900 rotate synchronously to throw out mud slurry, and when disassembling, the rotating shaft 900 can be separated to disassemble the bulk material structure 600 from the space.

[0067] The sludge treatment method and steps are as follows:

[0068] S1. The mud slurry is pumped in through the connecting pipe 400.

[0069] S2. The mud slurry 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.

[0070] S3. When the mud slurry passes through the fluid cavity, the particle aggregates in the mud slurry move randomly 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, the spring A 6053 is further compressed, the spring B 6056 also undergoes recoverable deformation, and the rubber sheet 6055 is pulled. Through the elastic force of the spring A 6053 and the spring 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 decompose after collision.

[0071] S4. After multiple collisions, the particle aggregates decompose and flow out of the fluid cavity along with the mud. The distributor formed by the fixed ring 700, connecting rod 800 and rotating shaft 900 rotates and throws the mud out. Then the mud is thrown out from the opening on the shaft of the screw conveyor and enters 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.

[0072] Working principle: The slurry is pumped in through the connecting pipe 400. After passing through the bulk structure 600, the slurry enters the fluid cavity formed by multiple rubber strips 6051, multiple connecting blocks 6052, and multiple rubber sheets 6055. As the slurry passes through the fluid cavity, the aggregated particles within it move randomly under the influence of the water flow, colliding with the contact block 6054. The instantaneous impact force causes the contact block 6054 to push the connecting block 6052. The connecting block 6052 moves along the space between adjacent rubber strips 6051. During this movement, the connecting block 6052 contacts the rubber strips 6051, and the spring A... 6053 is further compressed, and the spring piece B6056 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 aggregate. After multiple collisions, the particle aggregate decomposes. The distributor formed by the fixed ring 700, the connecting rod 800 and the rotating shaft 900 rotates and throws out the mud. Then, the mud is thrown out from the opening on the shaft of the screw conveyor and enters the rotating drum 100. After the differential rotation of the rotating drum 100 and the screw conveyor, solid-liquid separation occurs. 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.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

Through the elastic force of the spring A (6053) and the spring 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 by collision. S4. After multiple collisions, the particle aggregates decompose and flow out of the fluid cavity with the mud. With the rotation of the connecting shaft (200), the mud is thrown out from the distributor formed by the fixed ring (700), the connecting rod (800) and the rotating shaft (900). Then the mud is thrown out from the opening on the shaft of the screw conveyor and enters 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.
