Description

Technical Field

[0001] This utility model relates to the field of dredging equipment, and in particular to a device for cleaning caking coal slime. Background Technology

[0002] Well wastewater is usually collected and sent to sedimentation tanks. Because the wastewater has high turbidity, the sludge content is relatively high. In the sedimentation tank, the sludge cannot be discharged in time and often accumulates. Over time, this will affect the sludge settling effect. Therefore, regular dredging is very necessary.

[0003] Current dredging techniques typically involve pumping out the supernatant from the sedimentation tank and then manually entering to remove the sludge, although some engineering vehicles can assist in the process. However, the equipment used in these techniques generally cannot operate in water, and because sedimentation tank dredging requires drainage, the wastewater discharge from each unit must be shut down during this process. Dredging operations severely impact production, making the dredging process exceptionally cumbersome.

[0004] To address these issues, some sedimentation tanks have sloping bottoms and are equipped with immediate drainage systems. However, this design can lead to coal slime compaction, making thorough dredging more difficult. Currently, there is no suitable solution for this situation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sludge cleaning device that can operate in water without affecting normal underground production and is safe to operate.

[0006] The equipment includes ground base stations and dredging vehicles;

[0007] The ground base station is equipped with a high-pressure water delivery unit, a power unit, and a control unit.

[0008] The dredging vehicle includes a frame, a traveling mechanism, a sealed chamber, and a dredging unit; the traveling mechanism is mounted on the frame, and a sealed chamber is mounted on top of the frame. A control response unit is mounted inside the sealed chamber, and the control unit is signal-connected to the control response unit.

[0009] The dredging unit is located at the front of the frame, and the walking mechanism, the dredging unit, and the power unit are connected by hoses.

[0010] This achieves the effect of enabling the equipment to operate in water in conjunction with the sealed chamber;

[0011] The dredging unit includes an auger and a slurry pump;

[0012] The auger is positioned in front of the dredging vehicle, and multiple high-pressure nozzles are arrayed on the upper part of the auger. The high-pressure nozzles are connected to the high-pressure water delivery unit pipeline.

[0013] A slurry pump is installed at the rear of the middle section of the screw conveyor.

[0014] In other words, the ground base station outputs signals and power, and the control unit is connected to the control response unit in the sealed cabin. The signal response unit outputs electrical signals to control the walking mechanism and the dredging unit. The sealed cabin and the power unit are connected to the walking mechanism and the dredging unit by hoses, which can meet the requirements of the equipment for water-borne operations.

[0015] In the event of coal slime caking, the high-pressure water conveying unit can be activated to allow the high-pressure nozzles on the screw conveyor to directly impact the caking coal slime and work in conjunction with the screw conveyor to complete the coal slime cleaning.

[0016] The beneficial effects of this utility model are: it solves the problems of difficult and cumbersome dredging processes in existing sedimentation tanks. It enables water-based operation of the equipment, thereby optimizing the sedimentation tank dredging process without affecting normal production. In particular, the equipment is applicable to a wider range of working conditions, and can simultaneously clean caking coal slime during the dredging process. Furthermore, the equipment is safe to operate and easy to maintain. Attached Figure Description

The sealed chamber 2 contains a control response unit, and the control unit is signal-connected to the control response unit.

[0026] The dredging unit 3 is located at the front of the frame, and the walking mechanism 4, the dredging unit 3, and the power unit are connected by hoses.

[0027] This achieves the effect of enabling the equipment to operate in water in conjunction with the sealed chamber 2;

[0028] The dredging unit 3 includes an auger 32 and a slurry pump 31;

[0029] The auger 32 is positioned in front of the dredging vehicle, and multiple high-pressure nozzles 34 are arrayed on the upper part of the auger 32. The high-pressure nozzles 34 are connected to the high-pressure water delivery unit pipeline.

[0030] A slurry pump 31 is installed at the rear of the middle part of the screw conveyor 32.

[0031] Preferably, the high-pressure nozzle 34 is inclined downward.

[0032] In other words, the ground base station 1 outputs signals and power, and the control unit is connected to the control response unit in the sealed cabin 2. The signal response unit outputs electrical signals to control the walking mechanism 4 to walk and the dredging unit 3 to dredge. Based on the sealed cabin 2, and the setting of the power unit connected to the walking mechanism 4 and the dredging unit 3 by a rubber hose, the equipment can meet the requirements of water-crossing operation.

[0033] In the event of coal slime caking, the high-pressure water conveying unit can be activated to allow the high-pressure nozzles 34 on the screw conveyor 32 to directly impact the caking coal slime and work in conjunction with the screw conveyor 32 to complete the coal slime cleaning.

[0034] Example 1: The ground base station 1 includes a chassis, and a high-pressure water delivery unit, a power unit and a control unit are installed inside the chassis;

[0035] The power unit is a hydraulic pump station; the control unit is one or more of PLC, MCU or microcomputer.

[0036] The effect achieved in this way is driven by a hydraulic pump station, that is, by pressurized oil to drive each action unit, and by rubber hoses to transmit power.

[0037] In Example 2, the walking mechanism 4 is a tracked walking mechanism;

[0038] A set of tracked walking mechanisms is provided on both sides of the vehicle frame. The tracked walking mechanism includes a drive wheel and a track that is sleeved on the outside of the drive wheel and poweredly connected to the drive wheel.

[0044] Furthermore, an electric valve is installed on the pipeline connecting the high-pressure water delivery unit and the nozzle, and the electric valve is connected to the control unit.

[0045] The effect achieved in this way is to further improve the integration of the equipment.

[0046] In Example 4, the auger 32 has two sets of blades. The two sets of blades are symmetrically arranged with the center of the auger 32 as the axis. That is, the two sets of blades are opposite to each other and are arranged towards the middle of the auger 32.

[0047] Preferably, the inlet of the slurry pump 31 is located at the rear of the middle of the screw conveyor 32, and its discharge port discharges the slurry through a pipeline.

[0048] Furthermore, the sludge removal vehicle is equipped with an auger lifting cylinder 33 at the front, and the auger lifting cylinder 33 is angled.

[0049] Preferably, lifting cylinders are provided on both sides of the auger 32.

[0050] The effect achieved is to control the contact depth between the screw conveyor 32 blades and the silt, and to adjust the nozzle height accordingly.

[0051] When in use, the ground base station 1 outputs signals and power, and the control unit is connected to the control response unit in the sealed chamber 2. The signal response unit outputs electrical signals to control the walking mechanism 4 to walk and the dredging unit 3 to dredge. Based on the sealed chamber 2, and the setting of the power unit connected to the walking mechanism 4 and the dredging unit 3 by a rubber hose, the equipment can meet the requirements of water-crossing operation.

[0052] The auger 32 moves to transport sludge to the rear of its middle section to the slurry pump 31, and the slurry pump 31 discharges the sludge.
