[0001] The present invention relates to the technical field of ship unloaders, and in particular to an intelligent, long-distance, micron-level micro-mist negative pressure dust suppression, and an environment-friendly grab ship unloader. Background Art

[0002] With the rapid development of the global economy, humanity's exploitation of the natural environment has become increasingly frequent, leading to a severe environmental protection situation. Air pollution is a key environmental protection issue. A grab ship unloader is a device that uses a grab bucket to grab bulk cargo (such as coal, ore, grain, etc.) and unload it onto a conveyor belt. The grab ship unloader consists of a trolley traveling mechanism, a trolley traveling mechanism, a cantilever, a grab bucket, and a conveying system. The trolley traveling mechanism enables the ship unloader to move along the dock rails, while the trolley traveling mechanism enables the grab bucket to move on the cantilever. The cantilever supports the grab bucket, enabling it to pitch and rotate. The grab bucket grabs the cargo, and the conveying system transports the cargo to the designated location. The conveying system typically includes a belt conveyor or a chain conveyor.

[0003] During operation, the grab bucket grabs bulk cargo (such as coal, ore, grain, etc.) and unloads it onto the conveyor belt. However, during the bulk material transportation process, the existing equipment has serious dust problems. Dust occurs during the horizontal and vertical transmission processes, exacerbating air pollution.

[0004] How to ensure that materials do not raise dust is now the most urgent problem that equipment manufacturers and equipment users need to solve. Summary of the Invention

[0005] In order to solve the serious dust problem existing in the existing grab-type ship unloader during the ship unloading process, the present invention proposes an intelligent long-distance micron-level micro-mist negative pressure dust suppression and environmentally friendly grab-type ship unloader. A micro-mist dust suppression mechanism and a dry dust collection mechanism are provided to prevent the dust stirred up by the material entering the hopper at the moment the grab is opened from overflowing, and to avoid the dust overflowing during the transportation from top to bottom, thereby achieving the effect of suppressing dust.

[0006] To achieve the above-mentioned purpose, the present invention proposes an intelligent, long-distance, micron-level, micro-mist, negative pressure, dust-reducing, and environmentally friendly grab ship unloader, comprising a ship unloader, a discharge device provided on the ship unloader, the discharge device comprising a windshield wall and a hopper, a windshield wall provided above the hopper, a conveying device provided below the hopper, the windshield wall being a square structure, arranged in pairs along the four sides of the hopper, a plurality of nozzles provided on the upper portions of the plurality of windshield walls, the plurality of nozzles being equidistantly arranged, and a dust collection head provided below the hopper; The ship unloader is provided with a micro-mist dust suppression mechanism and a dry dust collection mechanism, wherein the micro-mist dust suppression mechanism is connected to a plurality of nozzles, and the dry dust collection mechanism is connected to a dust collection head; The micro-mist dust suppression mechanism and the dry dust collection mechanism are provided with a control module, which includes a controller and a detection mechanism.

When the dust particles move with the airflow, they collide with the water mist particles and stick together. As the agglomerated dust clusters become larger and heavier, they can easily fall to the ground, thus achieving dust suppression.

[0009] Furthermore, the screw air compressor is communicatively connected to the controller, the air storage tank is connected to a safety valve, a pressure gauge is provided on the air storage tank, and the pressure gauge is electrically connected to the controller; The water-gas distributor comprises a first proportional valve, a second proportional valve and a multi-way pipe, the water pipe is connected to the first proportional valve, and the gas pipe is connected to the second proportional valve; The other ends of the first proportional valve and the second proportional valve are connected to a multi-way pipe, and the multiple output ends of the multi-way pipe are respectively connected to a plurality of nozzles, and the nozzles are connected to the windshield wall through the universal joint assembly; The first proportional valve and the second proportional valve are electrically connected to the controller; The water pump is provided with a frequency converter, and the frequency converter is communicatively connected with the controller.

[0019] Through the above technical solution, the beneficial effects of the present invention are: 1 The present invention realizes dust-free operation of the grab-type ship unloader. A fully enclosed grab is provided to avoid dust caused by the falling of fine materials during transportation. The grab is opened at the hopper position. When opened, fine materials, dust and other floating objects float inside the windbreak wall. A micro-mist dust suppression mechanism is provided, which outputs micron-level water mist.

[0036] The nozzle 4 is installed in a stainless steel protective shell, and the stainless steel shell mounting seat can prevent the material from directly hitting the nozzle 4 during transportation.

[0037] The anemometer 7 is arranged at the upper end of the unloading device and is used to detect the high-altitude wind speed.

[0038] The conveying equipment 3 includes a discharge channel 21 and a belt conveyor 22. The discharge channel 21 is an inverted Y-shaped structure with three openings made of flexible material. The upper end of the discharge channel 21 is sealed with the lower end of the hopper 2, and the two openings at the lower end of the discharge channel 21 are respectively fixed to the belt conveyor 22. The two belt conveyors 22 are set on the ground.

[0039] The dry dust collection mechanism includes a fan 23 and a connecting pipe 24. The connecting pipe 24 is connected to the feeding channel 21 near the upper end thereof. The other side of the connecting pipe 24 is connected to the fan 23. The other end of the fan 23 is connected to a collection bin. The connecting pipe 24 is provided with a filter. The fan 23 is provided with a frequency converter, and the frequency converter is electrically connected to the controller 6 .

[0040] The ship unloader is further provided with a grab bucket 25 for grabbing materials. The grab bucket 25 is a fully enclosed grab bucket.

[0041] During operation, the anemometer 7, hygrometer 8, dust detector 9 and camera equipment 10 work separately. According to the actual situation, when the wind is strong, the air pressure needs to be increased to ensure that the water mist is sprayed far. According to the hygrometer, the air humidity is detected. In theory, the greater the air humidity, the less water mist, and vice versa. According to the detection of the dust detector 9, the power of the fan 23 is increased to improve the dust collection effect, and the amount of water mist and the size of the water mist area are properly controlled to achieve a dust reduction effect.

[0042] During operation, the screw air compressor 13 provides air, which flows through the air storage tank 14 and into the micron dry fog machine 11. Simultaneously, water from the water tank and air also enter the micron dry fog machine 11. The micron dry fog machine 11 filters the water and air, and a self-cleaning filter is included to clean the filter screen. The water in the micron dry fog machine 11 forms a mist, which flows through the water pipe and enters the water-gas distributor and the dry fog chamber controller. The gas output from the micron dry fog machine 11 flows through the air pipe and enters the water-gas distributor and the dry fog chamber controller.

[0043] The PLC controller controls the volume and pressure of water mist entering the multi-way pipe by adjusting the first and second proportional valves 16, 17. The pressurized water mist is then sprayed from the nozzles as fine mist (water droplet diameter 5-50µm). The micron-level dry fog machine 11 is connected to the PLC controller for communication, allowing the PLC to modify the operating parameters of the micron-level dry fog machine 11. The valve core positions of the first and second proportional valves 16, 17 can be adjusted, allowing the diameter, operating area, and volume of the fine mist to be adjusted according to actual conditions. Similarly, the PLC controller controls the volume and pressure of water mist entering the multi-way pipe by adjusting the third and fourth proportional valves 18, 19. The pressure is then applied to the dry fog chamber assembly 20 for spraying.

[0044] The PLC controller controls the speed of the fan 23 through the frequency converter to adjust the attraction of the dry dust collection mechanism.

[0045] During the operation, the fully enclosed grab bucket grabs the material and then comes to the top of the hopper 2. When the fully enclosed grab bucket reaches the position of the windshield wall 1, the hopper 2 opens. At this time, dust appears between the four windshield walls 1. The material enters the hopper and moves downward. Under the action of the dry dust collection mechanism, the dust is carried downward by the atmospheric pressure. Multiple nozzles 4 are set on the windshield wall 1. The nozzles 4 spray out fine mist (water droplet diameter 5-50µm). The fine mist and dust collide and contact with each other in the four windshield walls 1 and the hopper 2 and stick together. As the agglomerated dust clusters become larger and heavier, the dust clusters fall to achieve dust suppression.

[0046] During the falling process, the discharge channel 21 is a closed structure, dust cannot overflow, and the dry mist box assembly 20 performs secondary dust suppression. After the material is diverted, it directly enters the belt conveyor equipment 22, so there is no dust overflow, solving the dust problem.

[0047] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
