Description

Technical Field

[0001] The utility model belongs to the technical field of port loading and unloading, and relates to a cleaning and transportation device, in particular to a cleaning and transportation device suitable for cleaning coal accumulated around large-scale dry bulk cargo loading and unloading machinery in ports. Background Art

[0002] During the operation of large-scale dry bulk cargo loading and unloading machinery at ports, due to the influence of various factors, some coal dust and particles will be scattered from the outgoing and return belts of the conveyor to the tracks on both sides of the conveyor. These coal dust and particles gradually accumulate near the tracks, affecting the surrounding environment, aggravating the wear of the stacker's walking system and tracks, and even causing the stacker to derail or overturn. Therefore, it is necessary to regularly clean the ground near the tracks.

[0003] There are two main cleaning methods available. During water supply, flushing is used to flush coal-laden wastewater into the drainage ditch below the dam foundation. During water release, accumulated coal is manually removed and placed on a conveyor belt for subsequent discharge to the storage yard. However, these cleaning methods present several challenges: Flushing can easily clog the drainage ditch; manual cleaning while the conveyor belt is running poses significant safety risks due to the close proximity to the conveyor belt, which can easily lead to accidental contact with the pull wires, mechanical damage, and even fatalities. Furthermore, if cleaning is performed while the conveyor belt is stopped, coal dust left on the conveyor belt can generate secondary dust during startup.

[0004] In summary, the existing means of cleaning coal accumulation around large-scale dry bulk loading and unloading equipment in ports are single and rely entirely on manual cleaning. This is not only inefficient, but also poses safety hazards and environmental problems, and cannot meet current needs. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for clearing coal accumulation around large-scale dry bulk cargo loading and unloading machinery in ports, so as to overcome the problems raised in the above-mentioned background technology.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] A device for clearing coal accumulation around large-scale dry bulk cargo loading and unloading machinery in ports includes a steel structure platform of the loading and unloading machinery, and is characterized in that it also includes a support frame, a working platform, a vertical conveyor, a horizontal conveyor and a material guide trough. The working platform is installed on the steel structure platform of the loading and unloading machinery through the support frame, and the vertical conveyor is installed on the side of the steel structure platform of the loading and unloading machinery through a connecting piece. The top of the vertical conveyor extends from the bottom of the working platform, and a horizontal conveyor horizontally and obliquely arranged on the working platform is connected to the discharge port of the vertical conveyor. A material guide trough is provided below the discharge port of the horizontal conveyor, and the material guide trough extends to the belt conveyor.

[0008] Moreover, the connecting piece is a frame formed by bending a profile into a gate-shaped structure. After the gate-shaped frame is sleeved on the vertical conveyor, it is welded to the steel structure platform and support frame of the loading and unloading machinery.

[0009] Moreover, an upwardly inclined material collection port is provided at the bottom side end of the vertical conveyor, and a material feeding hopper is connected to the end of the material collection port through a flange.

[0010] Moreover, a filter is provided inside the feeding hopper, and a vibrator is provided on the outer wall of the feeding hopper.

[0011] The advantages and positive effects of the utility model are:

[0012] The utility model is suitable for a device for clearing away coal accumulation around large-scale dry bulk cargo loading and unloading machinery at ports. By transporting the accumulated materials longitudinally and transversely, a new mode of clearing away coal accumulation around large-scale dry bulk cargo loading and unloading machinery at ports is realized, thereby eliminating the potential safety hazards of cleaning the coal accumulation around the belt conveyor during operation and improving the efficiency of cleaning the coal accumulation. When the utility model is working, the belt conveyor does not need to be shut down, thereby solving the problem of secondary dust emission generated at startup due to coal accumulation falling from the belt conveyor in the prior art.

DETAILED DESCRIPTION

[0019] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0020] A device for clearing coal accumulation around large-scale dry bulk cargo loading and unloading machinery at ports, comprising a steel structure platform 1 of the loading and unloading machinery, a belt conveyor 2 being provided at the middle position of the upper end of the steel structure platform of the loading and unloading machinery, and a traveling wheel 12 being provided at the bottom of the steel structure platform of the loading and unloading machinery for facilitating its movement. The device is innovative in that it further comprises a support frame 7, a working platform 6, a vertical conveyor 8, a horizontal conveyor 4 and a guide trough 3. The working platform is installed on the steel structure platform of the loading and unloading machinery through the support frame, and a vertical conveyor is installed on the side of the steel structure platform of the loading and unloading machinery through a connecting piece 9. The vertical conveyor comprises a vertical conveyor body, and a vertical conveyor body is provided at the lower part of the vertical conveyor body. A collecting port 10 is provided, and a downwardly inclined transition cavity 5 is provided on the upper part of the vertical conveyor body, and a discharge port 11 is provided at the bottom of the transition cavity. The top of the vertical conveyor extends from the bottom of the working platform, and a horizontal conveyor horizontally inclined on the working platform is connected to the discharge port of the vertical conveyor. The horizontal conveyor includes a horizontal conveyor body, a receiving port and a discharge port. A receiving port corresponding to the discharge port of the vertical conveyor is provided at the top of one end of the horizontal conveyor body, and a discharge port is provided at the other end of the horizontal conveyor body. A material guide trough is provided below the discharge port of the horizontal conveyor, and the material guide trough extends to the middle of the belt conveyor.

[0021] The vertical conveyor and the horizontal conveyor are both screw conveyors.

[0022] In order to ensure the stability of the installation of the vertical conveyor, a connecting piece is provided on the vertical conveyor. The connecting piece is a frame bent from a profile into a gate-shaped structure. After the gate-shaped frame is mounted on the vertical conveyor, it is welded to the steel structure platform and support frame of the loading and unloading machinery.

[0023] An upwardly inclined material collection port is provided at the bottom side end of the vertical conveyor. To facilitate material feeding, a material feeding hopper 14 is connected to the end of the material collection port via a flange.

[0026] The accumulated coal around the large-scale loading and unloading machinery is collected manually and put into the hopper. Under the vibration of the vibrator, the accumulated coal enters the vertical conveyor. Under the action of the screw in the vertical conveyor, the coal inside is transported to the discharge port of the vertical conveyor and enters the horizontal conveyor through the receiving port. The coal is transported to the discharge port of the horizontal conveyor through the horizontal conveyor. The coal is transported to the belt conveyor through the discharge port of the horizontal conveyor and then transported to the yard by the belt conveyor, completing the removal of the accumulated coal around the large-scale loading and unloading machinery of dry bulk cargo at the port.
