Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically a sludge treatment equipment for river dredging. Background Technology

[0002] In river management and maintenance projects, dredging operations generate large quantities of complex, highly water-content fluid sludge. Traditional treatment methods often involve directly transporting this sludge to a stockpile for natural drying or using simple sedimentation tanks for preliminary separation. These methods are not only land-intensive, time-consuming, and inefficient, but also prone to generating foul odors and leachate during drying, causing secondary environmental pollution and contradicting current environmental protection requirements. Furthermore, during operation, the core crushing components of dredging equipment are easily worn or damaged when in contact with hard debris, and replacing these components with traditional equipment is cumbersome, time-consuming, and labor-intensive, severely impacting project progress.

[0003] Utility model patent CN221771618U discloses a sludge removal device for sewage treatment. Addressing the problems of difficult-to-remove impurities, poor flexibility, and difficulty in cleaning hardened sludge mentioned in the background art, the present invention proposes the following solution: It includes a vehicle body, with a sludge removal and pulverizing mechanism installed on one outer wall of the vehicle body. This mechanism includes a rotating plate rotatably connected to the outer wall of the vehicle body, a pulverizing motor bolted to the top outer wall of the rotating plate, and a pulverizing rod connected to the output shaft of the pulverizing motor via a coupling. This utility model reduces the equipment failure rate in the sludge removal and pulverizing mechanism, and by moving the vehicle body within the sewage tank, it can be transferred to any sewage point as needed, greatly improving the flexibility of sludge removal. The flushing mechanism efficiently removes hardened sludge, improving the sludge removal effect. Simultaneously, the flushing nozzles dilute the remaining sludge, providing excellent cleaning results.

[0004] However, the wastewater treatment sludge removal device is not convenient for replacing and cleaning damaged or maintenance-requiring cutter shafts during use, which increases downtime for maintenance and reduces the equipment's working efficiency and safety. Utility Model Content

[0005] This utility model provides a sludge treatment device for river dredging, which has the advantage of easy maintenance. It solves the problem that the dredging device for sewage treatment is inconvenient to replace and clean the damaged and maintenance-required cutter shaft during use, which increases downtime for maintenance and reduces the working efficiency and safety of the equipment.

[0006] To facilitate maintenance, this utility model provides the following technical solution: a sludge treatment device for river dredging, comprising a fixed shell and a housing, wherein a track is fixedly connected to the bottom of the housing, and further comprising: A hinge is provided on the back of the fixed housing, and a quick-change assembly is fixedly connected to the front of the fixed housing. The quick-change assembly includes a locking buckle and a retaining ring. A connecting plate is provided on the surface of the buckle, and a connecting rod is slidably connected inside the connecting plate; A support plate is provided on the top of the housing, and a compression assembly is fixedly connected to the top of the support plate. The compression assembly includes a cylinder and a pressing plate, and a filter screen is slidably connected to the surface of the pressing plate.

[0007] As a preferred embodiment of this utility model, the quick-change component includes a locking buckle fixedly connected to the front side of the fixed shell, and a buckle ring is slidably connected to the surface of the locking buckle.

[0008] As a preferred embodiment of the present invention, the compression assembly includes a cylinder fixedly connected to the top of the support plate, and a compression plate fixedly connected to the bottom of the cylinder.

[0009] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to one side of the connecting rod, and a fixing shell is fixedly connected to the back of the fixing plate.

[0010] As a preferred embodiment of this utility model, a rotating shaft is fixedly connected inside the second fixed shell, and a crushing blade is fixedly connected to the surface of the rotating shaft.

[0011] As a preferred embodiment of this utility model, a rotating block is inserted into the left side of the rotating shaft, and a motor is fixedly connected inside the rotating block.

[0012] As a preferred embodiment of this utility model, a bucket is fixedly connected to the right side of the motor, and a protective shell is fixedly connected to the left side of the bucket.

[0013] As a preferred embodiment of this utility model, a transmission arm is slidably connected to the surface of the bucket, and a protective grille is fixedly connected to the inside of the bucket.

[0014] Compared with the prior art, this utility model provides a sludge treatment device for river dredging, which has the following beneficial effects: This sludge treatment equipment for river dredging features a quick-change component design. When the crushing blade needs replacement, moving the connecting plate causes the retaining ring to rotate around the connecting rod. This rotation, in turn, loosens the retaining ring's locking mechanism. Moving the first and second fixed housings causes them to rotate around a hinge, separating the rotating shaft and the rotating block. This facilitates disassembly and replacement, allowing for easy replacement and cleaning of damaged or maintenance-requiring cutter shafts. It reduces downtime for maintenance and improves equipment efficiency and safety.

[0015] This sludge treatment equipment for river dredging utilizes a compression component. During operation, the cylinder is activated, causing it to move the extrusion plate downwards. This downward movement of the extrusion plate compresses the sludge inside the filter screen. As the sludge is compressed, the water in the sludge flows out through the drainage holes on the outside of the casing, thus achieving the compression effect. This facilitates solid-liquid separation of the sludge, reduces its volume and weight, and lowers the overall cost and difficulty of subsequent transportation and treatment.

[0018] 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.

[0019] Please see Figures 1-5 This utility model discloses a sludge treatment device for river dredging, including a fixed shell 1 and a shell 2. The bottom of the shell 2 is fixedly connected to a track 3. The device also includes: a hinge 4 on the back of the fixed shell 1; a quick-change assembly 5 fixedly connected to the front of the fixed shell 1, the quick-change assembly 5 including a locking buckle 501 and a buckle 502; a connecting plate 6 on the surface of the buckle 502, the inside of the connecting plate 6 being slidably connected to a connecting rod 7; a support plate 8 on the top of the shell 2, the top of the support plate 8 being fixedly connected to a compression assembly 9, the compression assembly 9 including a cylinder 901 and a pressing plate 902, the surface of the pressing plate 902 being slidably connected to a filter screen 10.

[0020] Specifically, the quick-change component 5 includes a locking buckle 501 fixedly connected to the front of the fixed housing 1, and a retaining ring 502 is slidably connected to the surface of the locking buckle 501.

[0021] In this implementation scheme, the locking buckle 501 provides quick locking and unlocking functions, and the buckle ring 502 cooperates with the locking buckle 501 to form an openable and closable connecting mechanism.

[0022] Specifically, the compression assembly 9 includes a cylinder 901 fixedly connected to the top of the support plate 8, and a compression plate 902 fixedly connected to the bottom of the cylinder 901.

[0023] In this embodiment, cylinder 901 provides a power source to drive the extrusion plate 902 to reciprocate up and down, applying pressure to the sludge. The extrusion plate 902 directly contacts and compresses the sludge, squeezing out the water.

[0024] Specifically, a fixing plate 11 is fixedly connected to one side of the connecting rod 7, and a fixing shell 12 is fixedly connected to the back of the fixing plate 11.

[0025] In this embodiment, the fixing plate 11 serves as a connection and support, and the fixing shell 12 also serves as a connection and support.

[0026] Specifically, a rotating shaft 13 is fixedly connected inside the fixed shell 12, and a crushing blade 14 is fixedly connected to the surface of the rotating shaft 13.

[0027] In this embodiment, the rotating shaft 13 transmits the power provided by the motor 16 and supports the crushing blade 14 to rotate at high speed. The crushing blade 14 cuts and crushes the collected sludge, breaking down large pieces of sludge and debris to facilitate subsequent compression and dewatering.

[0028] Specifically, a rotating block 15 is inserted into the left side of the rotating shaft 13, and a motor 16 is fixedly connected inside the rotating block 15.

[0029] In this implementation scheme, the rotating block 15 plays the role of transmitting motion, and the motor 16 plays the role of providing the core rotational power for the entire crushing system.

[0030] Specifically, a bucket 17 is fixedly connected to the right side of the motor 16, and a protective shell 18 is fixedly connected to the left side of the bucket 17.

[0031] In this implementation plan, the bucket 17 is used to dig and scoop up the silt from the bottom of the river, and the protective shell 18 is used to protect the key components inside, such as the motor 16, from being invaded and damaged by sludge, water or debris.

[0032] Specifically, a drive arm 19 is slidably connected to the surface of the bucket 17, and a protective grille 20 is fixedly connected inside the bucket 17.

[0033] In this implementation scheme, the transmission arm 19 controls the bucket 17 to perform digging, lifting, and dumping actions, while the protective grille 20 serves as a preliminary filter to prevent oversized solid debris from entering the bucket 17 and to protect the subsequent crushing and compression components.

[0034] The working principle and usage process of this utility model are as follows: When it is necessary to replace the crusher blade 14, by moving the connecting plate 6, the connecting plate 6 causes the buckle 502 to rotate around the connecting rod 7. By moving the buckle 502, the connecting plate 6 causes the buckle 502 to loosen the locking buckle 501. By moving the first fixed shell 1 and the second fixed shell 12, the first fixed shell 1 and the second fixed shell 12 rotate around the hinge 4. By moving the first fixed shell 1 and the second fixed shell 12 around the hinge 4, the rotating shaft 13 and the rotating block 15 are separated, thereby achieving the function of easy disassembly and replacement. In use, by activating cylinder 901, cylinder 901 drives the extrusion plate 902 to move downward. As the extrusion plate 902 moves downward, it compresses the sludge inside the filter screen 10. As the sludge is squeezed, the water in the sludge flows out through the water outlet on the outside of the housing 2, thereby achieving the compression effect.

[0035] In summary, this sludge treatment equipment for river dredging achieves the effect of easy disassembly and replacement through the quick-change component 5, which facilitates the replacement and cleaning of damaged or maintenance-requiring cutter shafts, reduces downtime for maintenance, and improves the working efficiency and safety of the equipment. Through the setting of the compression component 9, the compression effect is achieved, which facilitates the solid-liquid separation of sludge, reduces the volume and weight of sludge, and reduces the overall cost and difficulty of subsequent transportation and treatment.
