Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to a dust collecting hood for a feeding head of a ship unloader. Background Art

[0002] Ship unloaders are commonly used equipment for unloading materials from ships. During operation, the material is first picked up by the feeding head, then transported within the machine body, and finally stored through an air chute. When the feeding head picks up the material, a large amount of dust is generated. In order to collect dust and reduce pollution to the environment, a dust hood is installed on the feeding head in the prior art. The dust hood is provided with a dust collecting port on the side, and the dust collecting port is connected to the dust collecting system. When the feeding head picks up the material, the dust enters the dust collecting hood body and is then collected in the dust collecting system through the dust collecting ports on both sides. The wind speed in the area near the dust collecting port in the dust collecting hood is relatively fast and the suction force is relatively large, which can quickly collect the dust in this area; however, the wind speed in the area far from the dust collecting port in the dust collecting hood is relatively slow, the air volume is small, and the suction force on the dust is relatively small, resulting in the inability to effectively collect the dust in this area. The dust will leak out, thereby polluting the environment. Utility Model Content

[0003] The purpose of the utility model is to provide a dust collecting hood for a feeding head of a ship unloader, wherein the suction force on all sides of the dust collecting hood tends to be uniform, thereby preventing local leakage of dust and overcoming the defects of the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A dust collecting hood for a ship unloader feeding head comprises a dust collecting hood body, the dust collecting hood body having a cavity with open upper and lower ends, two dust collecting ports symmetrically provided on the sides of the cavity, both dust collecting ports having passages communicating with the cavity, the passages being open at upper and lower ends, a mesh plate surrounding the feeding head being detachably mounted at the lower end of the cavity, the mesh plate being provided with guide holes for guiding the airflow to be uniform.

[0006] By adopting the above technical solution, by adding a grid plate to the dust hood, the distribution of the airflow can be guided during inhalation, so that the air volume in the area away from the air intake port is increased, the wind speed becomes faster, and the suction force is enhanced, so that the airflow of the inhaled air in the dust hood tends to be uniform, thereby avoiding the problem of dust leakage caused by insufficient suction force in the area away from the air intake port.

[0007] In a specific embodiment of the present invention, the guide holes are long holes extending radially, and the long holes are evenly spaced along the circumference on the grid plate.

[0008] In a specific implementation manner of the present utility model: the dust collecting port includes an inclined section and a vertical section.

[0009] In a specific implementation manner of the present utility model: the dust collecting port is fixed on the dust collecting hood body by welding.

[0010] In a specific embodiment of the present invention, the dust collecting hood body is made of steel. The dust collecting hood made of steel can not only withstand external pressure and impact under various complex working conditions, but also has the advantages of strong corrosion resistance, long service life, and easy maintenance.

[0011] In a specific embodiment of the present invention, the upper opening of the cavity is peach-shaped to match the shape of the motor seat of the feeding head, and the lower opening of the cavity is circular. The above technical solution allows for quick disassembly and assembly of the dust hood.

[0012] In a specific implementation manner of the present invention: the two dust collecting ports are respectively connected to the dust collecting system through flanges.

[0013] In summary, the dust collecting hood of the present invention collects dust generated during the operation of the feeding head through the air intakes on both sides of the channel, which can significantly improve its dust collection effect and reduce environmental pollution. By adding a mesh plate at the lower end of the cavity, the guide holes on the mesh plate can guide the distribution of the airflow during the suction, so that the air volume and wind speed in the area away from the air intake increase, and the suction force is enhanced, thereby making the airflow of the suction in the dust collecting hood more uniform, thereby avoiding dust leakage in local locations and improving the dust collection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Figure 1 This is a schematic structural diagram of a dust collecting hood for a feeding head of a ship unloader according to the present invention;

[0016] Figure 2 It shows that the dust collecting hood is put on the feeding head. DETAILED DESCRIPTION

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1 and Figure 2 As shown, the utility model is a dust collecting hood for a ship unloader feeding head, comprising a dust collecting hood body 10. The dust collecting hood body 10 has a cavity 11, and the upper and lower ends of the cavity 11 are open.

[0019] like Figure 1 As shown, two dust collecting ports 12 are symmetrically provided on the side of the cavity 11. The interiors of the two dust collecting ports are provided with a channel 13 communicating with the cavity 11. The upper and lower ends of the channel 13 have openings 123.

[0020] In this embodiment, the dust collecting port 12 includes an inclined section 121 and a vertical section 122 .

[0021] The two dust collecting ports 12 are fixed to the dust collecting cover body 10 by welding. With the above structure, the number of parts can be reduced and the installation is convenient.

[0022] In this embodiment, the dust collecting hood body 10 is made of steel. The dust collecting hood made of steel can not only withstand external pressure and impact under various complex working conditions, but also has the advantages of strong corrosion resistance, long service life and easy maintenance.

[0023] like Figure 1 and Figure 2 As shown, a mesh plate 14 surrounding the feeding head is detachably mounted at the lower open end of the cavity 11 .

[0024] In this embodiment, the grid plate 14 is a circular structure. The grid plate 14 has a circular hole 141 in the middle for the feeding head to pass through. The grid plate 14 is also distributed with guide holes 142 for guiding the airflow to be more uniform.

[0025] In this embodiment, the guide holes 142 are radially extending elongated holes that are evenly spaced along the circumference of the mesh plate. By adding the mesh plate to the dust hood, the above technical solution can guide the distribution of the airflow during suction, increasing the air volume and speed in areas away from the air inlet, and enhancing the suction force. This makes the airflow within the dust hood more uniform, thus avoiding dust leakage caused by insufficient suction force in areas away from the air inlet.

[0026] like Figure 2 As shown, in addition, the shape of the upper opening of the cavity 13 is adapted to the shape of the bottom surface of the motor seat on the feeding head 17. In the present embodiment, the upper opening of the cavity 13 is a peach-shaped structure. The lower opening of the cavity 13 is circular.

[0027] The upper openings 123 of the two dust collecting ports 12 are connected to the dust collecting system 16 through flanges 15 respectively.

[0028] During assembly, the grid plate 14 is bolted to the lower opening of the cavity 11. The dust hood body 10 is fitted over the feed head, with the upper opening bolted to the bottom of the feed head's motor base. The upper openings 123 of the two dust collection ports are connected to the dust collection system 16 via flanges 15. When the feed head is operating, dust generated by the material enters the cavity 11 of the dust hood body. The dust is then sucked away by the lower openings 123 of the channels on both sides and collected in the dust collection system 16.

[0029] In summary, the dust collecting hood of the present invention collects dust generated during the operation of the feeding head through the dust collecting ports on both sides, which can significantly improve its dust collection effect and reduce environmental pollution. By adding a mesh plate at the lower end of the cavity, the guide holes on the mesh plate can guide the distribution of the airflow during suction, increasing the air volume, speed and suction force away from the suction port, thereby making the airflow of the suction in the dust collecting hood more uniform, thereby avoiding dust leakage in local locations and improving the dust collection effect.

[0030] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
