Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment for ship unloaders, and in particular to a spray dust removal system for ship unloaders. Background Technology

[0002] During bulk cargo loading and unloading at ports, large amounts of dust are easily generated at the unloader hopper, causing environmental pollution and health hazards. Existing technologies often employ water mist spraying or airflow dust suppression, but these methods suffer from low dust removal efficiency, uneven coverage, and susceptibility to wind direction. For example, fixed nozzles cannot adapt to changes in material drop points, and simple water mist dust suppression is significantly less effective in strong winds. Therefore, a highly efficient dust removal system capable of dynamic adjustment and multi-mechanism synergy is needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spray dust removal system for ship unloaders. Through the coordinated action of multiple mechanisms, it achieves three-dimensional and precise suppression and removal of dust generated during the unloading process, effectively improving dust removal efficiency.

[0004] According to an embodiment of the present invention, a spray dust removal system for a ship unloader includes four vertically arranged barriers fixed to the top of the hopper. A pair of opposing barriers are provided with blocking eaves. Each of the two blocking eaves is provided with a water curtain mechanism facing the opposite side and a dust detector located on the inner side of its top. The barriers are also provided with an airflow mechanism facing the middle of the hopper. The dust detector is located below the water curtain mechanism. Each barrier is provided with a horizontal water mist mechanism facing the opposite side and an exhaust mechanism located below the water mist mechanism and vertically downward.

[0005] Preferably, the water curtain mechanism includes a water spray pipe rotatably connected to the obstruction eaves, and the water spray pipe is fixedly provided with water spray heads evenly distributed along its axial direction. The water spray pipe is rotatable and is connected to a first adjusting member disposed on the obstruction eaves.

[0006] More preferably, the water spray heads on the two obstruction eaves are distributed alternately. More preferably, the airflow mechanism is provided in two sets, each set of the airflow mechanism including two support components rotatably connected to the two opposite sides of the enclosure, a power component that drives the two support components to move synchronously, and a jet component disposed between the two support components.

[0007] More preferably, the support assembly includes two parallel support rods rotatably connected to the outer wall of the enclosure, the rotation axes of the plurality of support rods are located on the same horizontal plane and their tops are rotatably connected to a horizontally arranged support plate, and the airflow mechanism is provided on the support plate.

[0008] More preferably, the jet assembly includes a jet pipe rotatably connected to the support plate and capable of rotation, a second adjusting member disposed on the support plate and pulsatorically connected to the jet pipe, and jet heads uniformly distributed along its axial direction and facing the center of the hopper are fixedly provided on the jet pipe.

[0009] In a further preferred embodiment, one side of the obstruction eaves is rotatably connected to the enclosure, and the enclosure is provided with an adjustment mechanism that is pulsatorically connected to the obstruction eaves.

[0010] Compared with the prior art, the present invention has the following beneficial effects: Through multiple dust suppression mechanisms including water curtain, water mist, and airflow, combined with real-time feedback from dust detectors, efficient and adaptive dust removal is achieved. The water spray pipes and air jet pipes are adjustable in angle to ensure that the coverage of the water curtain and airflow matches the material landing point. The obstruction eaves are adjustable in tilt angle to enhance the dust blocking effect. The downward airflow generated by the airflow mechanism not only suppresses dust from rising but also responds to the suction airflow generated by the bottom exhaust mechanism, effectively preventing dust from escaping outward.

The exhaust mechanism 7 includes a chamber fixed on the inner side of the enclosure 1. The bottom of the chamber is provided with an exhaust hole. A vacuum pump is connected outside the chamber to generate a suction effect and cooperates with the airflow mechanism 5 to generate an airflow effect from top to bottom and from the center to the surroundings. To facilitate adjustment of the water curtain angle generated by the water curtain mechanism 4, in a further embodiment, the water curtain mechanism 4 includes a water spray pipe 401 rotatably connected to the obstruction eaves 2. The water spray pipe 401 is fixedly provided with water spray heads 402 evenly distributed along its axial direction.

Specifically, such as Figure 3As shown, the support assembly 510 includes two parallel support rods 511 that are rotatably connected to the outer wall of the enclosure 1. The rotation axes of the multiple support rods 511 are located on the same horizontal plane, and their tops are rotatably connected to a horizontally arranged support plate 512.

In this embodiment, the power assembly 520 includes an electric push rod rotatably connected to the enclosure 1 and a transmission rod fixedly connected to one of the support rods 511.
