Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering and sewage treatment, in particular to a silt removal device. Background Art

[0002] Water conservancy projects, sewage treatment, etc. require sludge cleaning operations. Currently, sludge cleaning is mostly done manually. Due to the working environment, manual sludge cleaning is prone to cause safety accidents such as physical injuries or falls from heights. In addition, manual work efficiency is low.

[0003] Existing dredging devices, such as a sewage pipe inspection well dredging device and dredging method disclosed in patent publication number CN110067303A, include a frame, a winch installed above the frame, a bucket lifted by the winch, and a spiral blade installed in the bucket. The mouth of the bucket faces downward, and the spiral blade is driven by a motor installed above the bucket. When in use, the dredging device is moved to the mouth of the sewage pipe inspection well, and the winch is started to put the bucket into the inspection well. The motor is started to drive the spiral blade to rotate and transport the sludge into the bucket. The bucket is then lifted by the winch, and the silo runs with the shuttle car to the bottom of the bucket, and the sludge in the bucket is poured into the silo.

[0004] This device can reduce the labor intensity of manual work and reduce the physical harm of the environment to the dredging personnel. However, the sludge is collected by a bucket integrated with the spiral blade, and the collection space is limited. In addition, the dredging of the bucket requires the use of a winch, and it is necessary to wait for the silo to run under the bucket before dumping, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0025] like Figure 1 As shown, a dredging device provided in this embodiment includes a driving mechanism 1, a bolt 2, a protective cover 3, a lifting ear 4, a coupling 5, a support seat 6, a storage tube 7, a spiral feeder 8, a cable 9, a storage bag 10, a controller 11 and an overflow pipe 12.

[0026] like Figure 2 As shown, the spiral feeder 8 includes a first limit switch 81 , a bearing seat 82 , a second limit switch 83 , a feeding pipe 84 , a feeding shaft 85 , a spiral blade 86 and a mounting platform 57 .

[0027] The center of the mounting platform 87 is provided with a mounting hole, and the bearing seat 82 is mounted in the mounting hole. The upper end surface of the feed pipe 84 is connected to the lower surface of the mounting platform 87, and the lower end of the feed pipe 84 is through. The feed shaft 85 is installed inside the feed pipe 84, and the feed shaft 85 passes through the bearing seat 82 in the mounting hole and extends to the outside to be connected to the output shaft of the planetary reducer 102 through the coupling 5. The spiral blade 86 is connected to the feed shaft 85. The outer ring of the coupling 5 contacts the inner wall of the mounting hole, and the inner ring is connected to the feed shaft 85.

[0028] The driving mechanism 1 includes a motor 101 and a planetary reducer 102. The motor shaft of the motor 101 is connected to the input end of the planetary reducer 102. The output end of the planetary reducer 102 is connected to the feed shaft 85 through a coupling 5. The flange of the motor 101 is connected to the flange of the planetary reducer 102 through bolts 2.

[0029] The mounting platform 87 is fitted on the lower surface of the support seat 6 , and the flange on the planetary reducer 102 is fitted on the upper surface of the support seat 6 . The mounting platform 87 , the planetary reducer 102 and the support seat 6 are connected by bolts 2 .

[0030] The lower end of the feeding shaft 85 extends out of the lower outer side of the feeding pipe 84 and is provided with a first limit switch 81 and a second limit switch 83 located above the first limit switch 81. The first limit switch 81 is located directly below the feeding pipe 84. A protective cover 3 is detachably mounted on the lower end of the feeding pipe 84, and the protective cover 3 is provided outside the lower end of the feeding shaft 85.

[0031] The number of the receiving tubes 7 is at least two, and the overflow tube 12 and the receiving bag 10 are arranged one by one with the receiving tubes 7. The receiving tube 7 includes an inclined tube 71 and a straight tube 72 connected to the lower end of the inclined tube 71. The upper end of the inclined tube 71 is connected to the feeding tube 84 of the spiral feeder 8, and the straight tube 72 is connected to the receiving bag 10. The length of the inclined tube 71 is longer than that of the straight tube 72. The overflow tube 12 is obliquely connected between the straight tube 72 and the top of the receiving bag 10. A third limit switch 121 is provided at the bottom of the overflow tube 12. At least two receiving bags 10 collect sludge at the same time, which greatly increases the capacity of sludge collection and reduces the number of sludge dumping times.

[0032] The upper surface of the support seat 6 is provided with a lifting lug 4. The driving mechanism 1, the first limit switch 81, the second limit switch 83 and the third limit switch 121 are electrically connected to the controller 11 through the cable 9. A small channel is provided in the center of the feeding shaft 85 for installing a part of the cable 9.

[0033] The third limit switch 121 is used to sense whether the storage bag 10 is full. When the storage bag 10 is full of sludge, the sludge in the storage tube 7 flows out from the overflow tube 12, or the material in the storage bag 10 directly contacts the bottom of the overflow tube 12. When the third limit switch 121 is triggered, a signal is sent to the controller 11, and the controller 11 shuts down the driving mechanism 1.

[0034] Before use, use a sling to hoist the dredging device to the working position and remove the protective cover 3. Lower the dredging device. When the first limit switch 81 touches the silt, send a signal to the controller 11 to start the driving mechanism 1, thereby driving the feeding shaft 85 of the screw feeder 8 to rotate, and slowly lower the dredging device while rotating to extract the silt. When the silt fills the spiral feeding pipe 84, the silt flows from the feeding pipe 84 into the receiving pipe 7, and then flows from the receiving pipe 7 into the receiving bag 10. At this time, there is no need to stop the spiral feeder, and there is no need to lift the spiral feeder to allow the silt in the feeding pipe 84 to flow into the receiving bag 10 by itself, which is more effective.

[0035] When the storage bag 10 is full, the sludge flows from the storage pipe 7 to the overflow pipe 12, thereby triggering the third limit switch 121 at the bottom of the overflow pipe 12, and the driving mechanism 1 is shut down through the controller 11. Then the dredging device is lifted, the full storage bag 10 is removed, the empty storage bag 10 is emptied, and then the empty storage bag 10 is installed or other empty storage bags 10 are directly installed. Then the first limit switch 81 is reset by the controller 11. Repeat the above steps to continue dredging.

[0036] When the silt removal device reaches the bottom of the silt, the second limit switch 83 is closed under the dual pressure of the silt removal device's own gravity and the bottom reaction force of the ditch where the silt is installed, generating a signal, so that the controller 11 shuts down the driving mechanism 1. Then the silt removal device is switched to another operating position. The controller 11 resets the second limit switch 83, repeats the above, and continues to remove silt.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
