Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically to a new type of sludge dredging skid that is easy to transport. Background Technology

[0002] In the field of wastewater treatment, sludge treatment is a crucial step, as its effectiveness directly impacts environmental quality and the efficient utilization of resources. However, traditional sludge treatment technologies have revealed numerous problems in practical applications, including high costs and low efficiency, insufficient technology adaptability, and environmental risks, severely hindering the development and progress of the sludge treatment industry. Traditional sludge treatment relies on fixed equipment, which has high purchase costs, large land areas, and long installation periods. Small and medium-sized enterprises and temporary projects cannot afford the initial investment, resulting in high equipment idle rates. Furthermore, sludge contains pollutants such as heavy metals, and manual dredging operations cause severe environmental pollution and harm to the health of construction workers. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a new type of dredging skid that is easy to transport, in order to solve the problems of high cost, easy clogging, low efficiency and secondary pollution of existing dredging equipment.

[0004] To solve the above problems, the technical solution of this utility model is as follows: a new type of dredging skid that is easy to transport includes a base, a frame on the base, a partition plate inside the frame, a dredging robot on the partition plate, a lifting device on one side of the frame and on the base for lifting the dredging robot out of the frame, and a control device and a hydraulic station for providing power to the lifting device, which are integrated and installed in the frame.

[0005] Furthermore, the lifting device includes a fixed base fixed to the base, a rotating chassis rotatably connected to the fixed base, and a mechanical arm fixed to the rotating chassis. An electric hook and a control rod are provided at the end of the mechanical arm.

[0006] Furthermore, the dredging robot includes a vehicle body and a tracked movement mechanism. A suction port is provided at the front end of the vehicle body, and a spiral cutter is provided on the outside of the suction port. The suction port is connected to a suction pipe and a chemical pump. A spraying mechanism for spraying diluted sludge is provided on the vehicle body. The dredging robot is connected to the control device via wires.

[0007] Furthermore, the spraying mechanism includes a fixed frame fixed to the vehicle body, a spray head on the fixed frame, and a water tank and a high-pressure water pump located within the frame.

[0008] Furthermore, the spray head is connected to an oil-water separator and an air compressor.

[0009] Furthermore, an ultrasonic mud level sensor is installed on the mounting bracket.

[0010] Furthermore, a gas alarm is installed within the frame.

[0011] Furthermore, the control device includes a PLC controller and a power distribution box.

[0012] Furthermore, a liquid level sensor is installed inside the water tank and is connected to the PLC controller.

[0013] Compared with the prior art, this utility model has the following advantages: convenient transportation and high degree of integration. The frame-base is a whole skid-mounted structure that is assembled in the factory at one time. It can be hoisted and fixed as a whole without disassembly during transportation, reducing the time and labor required for secondary assembly on site.

[0014] The dredging robot adopts a composite process of tracked walking, spiral cutter crushing, and high-pressure water jet dilution, which can complete crushing, dilution and suction in one go, significantly improving the dredging efficiency of high-viscosity sludge.

[0015] PLC remote control and ultrasonic mud level sensor closed-loop adjustment of spray pressure and suction pump speed achieve thin-layer uniform suction, avoiding over-suction or empty suction, keeping workers away from sludge, avoiding pollution and injury.

[0016] The modular design allows for functional expansion as needed (such as adding sludge dewatering devices or extending suction pipes), making it suitable for dredging operations in municipal pipe networks, small rivers, oil tanks, industrial sedimentation tanks, and other scenarios, and especially suitable for emergency dredging tasks.

Detailed Implementation

[0019] I. Overall Structure like Figure 1-3As shown, the dredging skid includes a base 1, a rectangular frame 2 welded on the base 1, a horizontal partition plate 3 welded inside the frame 2, and a dredging robot 4 placed on the partition plate 3. Lifting lugs can be welded to the upper end of the frame 2 for easy lifting, and protective plates can also be added to further protect the internal equipment. A lifting device 5 is fixed on the base 1 on one side of the frame 2. The frame 2 integrates a control device 6, a hydraulic station 7, a water tank 8, an oil-water separator 11, a high-pressure water pump 9, an air compressor 12, and a chemical pump 13.

[0020] II. Structure and Connection Relationship of Core Components like Figure 1 , 2 As shown, the lifting device 5 includes a fixed base 51 (with built-in rotary bearing) fixed to the base 1. A rotating chassis 52 (which can rotate 360°) is rotatably connected to the fixed base 51. A mechanical arm 53 is connected to the rotating chassis 52 via a hydraulic cylinder. An electric hook 54 is installed at the end of the mechanical arm 53. A control rod 55 is provided on the side of the frame 2 and is connected to a hydraulic station 7 via a hydraulic pipeline to control the extension, rotation, and lifting and lowering of the mechanical arm 53 and the electric hook 54. like Figure 3 As shown, the dredging robot 4 adopts a tracked movement mechanism 41, which can be driven by a DC motor and the speed can be adjusted by the control device 6. The front end of the vehicle body 46 is equipped with a spiral cutter 42, which can be driven by a hydraulic motor. The spiral cutter 42 has a suction port 43 on its inner side. The suction port 43 is connected to an external sludge storage tank or sludge dewatering device through a suction pipe 44 and a chemical pump 13. The spraying mechanism 45 includes a fixed frame 451. A spray head 452 is installed at the end of the frame. The spray head 452 is connected to a high-pressure water pump 9 through a high-pressure water pipe. The inlet of the high-pressure water pump 9 is connected to a water tank 8. The spray head 452 is also connected to an oil-water separator 11 and an air compressor 12, which periodically spray high-pressure gas into the spray head 452 to prevent impurities in the water from clogging the spray head 452. An ultrasonic mud level sensor is installed on the fixed frame 451. The sensor signal is transmitted to the control device 6 through a wire. like Figure 2 As shown, the control device 6 includes a PLC controller 61 with a touch screen and a power distribution box 62. The power distribution box 62 supplies power to the dredging robot 4, the hydraulic station 7, and the high-pressure water pump 9. The PLC controller 61 receives signals from the ultrasonic mud level sensor 46 and the gas alarm 10, and outputs instructions to control the operation of each device. like Figure 2 As shown, the gas alarm 10 is installed on the top of the frame 2 to detect gases such as methane and hydrogen sulfide (detection range 0-100% LEL). When the limit is exceeded, it triggers an audible and visual alarm and sends a shutdown signal to the PLC controller 61. Water tank 8 is equipped with a level gauge (linked to PLC, alarming when the level is low), and high-pressure water pump 9 draws water from the water tank, pressurizes it and delivers it to the spray head 452.

[0021] III. Work Process Transportation and Deployment: The dredging skid is transported to the work site by trailer. The hoisting device 5 is started by operating the control lever 55. The rotating mechanical arm 53 lifts the dredging robot 4 to the ground. The connection between the hook 54 and the robot is disconnected. Dredging operation: The operator starts the dredging robot 4 through the control device 6, and the tracked moving mechanism 41 drives the robot into the silt area; the ultrasonic mud level sensor 46 detects the thickness of the silt, and the PLC controller 61 automatically adjusts the speed of the spiral cutter 42 according to the thickness (increases the speed to 50 r / min in the thick silt area and reduces it to 20 r / min in the thin silt area); the high-pressure water pump 9 is started, and the spray head 452 sprays high-pressure water onto the silt. After the diluted silt is broken by the spiral cutter 42, it is sucked in through the suction port 43 and discharged through the suction pipe 44 to the silt dewatering device.

[0022] Recovery and Transfer: After the operation is completed, the lifting device 5 lifts the dredging robot 4 back onto the partition plate 3 of the frame 2. After it is fixed, it can be transferred to the next operation point by the traction hook of the base 1. This embodiment achieves convenient transportation and rapid operation of dredging equipment through integrated design, and is especially suitable for small and medium-sized dredging scenarios such as small-diameter urban pipe networks and septic tanks in residential areas. It has the advantages of high automation, simple operation and strong safety.
