Description

Technical Field

[0001] This utility model relates to the field of dry fog dust suppression devices, specifically a dry fog dust suppression device for a ship unloader. Background Technology

[0002] A ship unloader is a specialized machine that lifts bulk materials from the ship's hold and unloads them onto the shore. It uses a continuous conveyor to create a machine head that can lift bulk materials, or it may have its own material handling capability, or it may be equipped with material handling and feeding devices to continuously lift bulk materials from the ship's hold, then unload them onto the boom or frame and transport them to the main conveyor system on the shore.

[0003] Existing ship unloaders typically use a grab bucket to directly pour materials into the hopper. However, during use and observation, it has been found that the falling material disturbs the surrounding airflow, causing small particles to fly around, which generates a large amount of dust and pollutes the surfaces of surrounding components.

[0004] Therefore, a dry fog dust suppression device for ship unloaders is proposed to address the above problems. Utility Model Content

[0007] Preferably, multiple baffles are fixedly connected to the middle of the upright plate; multiple fixing holes are opened in the middle of the baffles; the fixing holes and the atomizing nozzles are correspondingly set; by setting the baffles, the baffles will block the dust diffused in the air, reduce the pollution effect of dust on the surface of the water spray pipe, and extend the service life of the water spray pipe.

[0008] Preferably, a water distribution plate is fixed to the inner wall of the baffle; a water inlet groove is symmetrically formed in the middle of the water distribution plate; the water inlet groove is inclined; the water distribution plate is located at the bottom of the spray pipe; part of the water mist sprayed from the atomizing nozzle will reach the inner wall of the baffle, and after these water mists come into contact with the baffle, they will liquefy into water droplets, and then the water droplets will flow along the inner wall of the baffle and reach the surface of the water distribution plate, and then the water will flow out along the water inlet groove, reducing the wastewater accumulation at the connection between the baffle and the vertical plate, and reducing the corrosive effect of wastewater on the vertical plate and the baffle.

[0009] Preferably, a first limiting plate is symmetrically fixed to the inner sidewall of the baffle; a second limiting plate is symmetrically fixed to the middle of the water spray pipe; the first limiting plate and the second limiting plate are correspondingly arranged; when the water spray pipe rotates under the meshing action of the sector gear and the parallel gear, the water spray pipe will bring the second limiting plate closer to the first limiting plate. When the second limiting plate and the first limiting plate come into contact, they will apply resistance to the water spray pipe, causing the water spray pipe to rotate quickly under the action of gravity, limiting the rotation amplitude of the water spray pipe, and reducing excessive squeezing of the water inlet pipe by excessive rotation of the water spray pipe.

[0010] Preferably, a plurality of first magnets are fixedly attached to the surface of the first limiting plate; a plurality of second magnets are fixedly attached to the surface of the second limiting plate; the first magnets and the second magnets are arranged correspondingly; when the second limiting plate and the first limiting plate are close together, the second magnets and the first magnets will also be close to each other, and the second limiting plate will be subjected to the repulsive force between the first magnets and the second magnets, so that the water spray pipe will be subject to additional resistance when rotating upward, thereby slowing down the rotation speed of the water spray pipe, making the water mist distribution within the range more uniform, and improving the dust suppression effect of the water mist on dust.

[0011] Preferably, multiple sponges are fixed to the surface of the water spray pipe; the sponges are equidistantly arranged; when the water spray pipe rotates, it will drive the sponges to move together, and the sponges will clean the inner wall of the upright plate when they rotate, thereby improving the cleanliness of the inner wall of the upright plate and reducing the friction between the water spray pipe and the upright plate when it rotates.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, a dry fog dust suppression device for a ship unloader includes a hopper 1; a pair of vertical plates 12 are installed on the top of the hopper 1; multiple water spray pipes 15 are rotatably connected to the inner sidewall of the vertical plates 12; a flat gear 17 is fixedly connected to the middle of the water spray pipes 15; multiple atomizing nozzles 18 are installed on the surface of the water spray pipes 15; a water inlet pipe 16 is connected to the middle of the water spray pipes 15; a motor 13 is fixedly connected to the middle of the vertical plates 12; and a rotatable gear 17 is fixedly connected to the middle of the vertical plates 12. Multiple rotating shafts 19 are connected; a belt is fitted between the output end of the motor 13 and the rotating shaft 19; a sector gear 14 is fixedly connected to both the output end of the motor 13 and the end of the rotating shaft 19; the sector gear 14 and the flat gear 17 are meshed; the water inlet pipe 16 is a flexible structure; during operation, the grab bucket will move to the top of the discharge hopper 1 and release the material. When the material flows in the air, it will generate dust. At this time, high-pressure water mixed with air can be pumped out along the water inlet pipe 16 by an air compressor, booster pump, or other equipment. The water is fed into the spray pipe 15, where it is sprayed out in a mist form through the atomizing nozzle 18. Simultaneously, the motor 13 is activated, causing the sector gear 14 to rotate. The rotation of the sector gear 14 meshes with the flat gear 17, which in turn drives the spray pipe 15 to rotate along the vertical plate 12. During this process, the angle of the atomizing nozzle 18 changes. When the sector gear 14 and flat gear 17 stop meshing, the spray pipe 15 resets under gravity, causing the angle of the sprayed water mist to continuously change until the sector gear 14 rotates back to mesh with the flat gear 17. This causes the water mist to spray up and down repeatedly. This water mist combines with airborne dust and causes it to settle, achieving dust suppression during grab bucket loading. The atomizing nozzle 18 rotates along with the spray pipe 15 under the meshing action of the sector gear 14 and flat gear 17, continuously changing the angle of the sprayed water mist, increasing the distribution range of the water mist, and expanding the contact area between the water mist and dust, thus effectively suppressing dust during grab bucket loading.

[0025] Please see Figure 2 and Figure 5 As shown, multiple baffles 2 are fixedly connected to the middle of the upright plate 12; multiple fixing holes 22 are opened in the middle of the baffles 2; the fixing holes 22 and the atomizing nozzles 18 are correspondingly arranged; the water mist sprayed from the atomizing nozzles 18 will be sprayed out from the fixing holes 22. When the grab bucket feeds the hopper 1, the material will diffuse under the action of gravity, and some dust will flow to the surface of the water spray pipe 15. At this time, the baffles 2 will block these materials; by setting the baffles 2, the baffles 2 will block the dust diffused in the air, reduce the pollution effect of dust on the surface of the water spray pipe 15, and extend the service life of the water spray pipe 15.

[0026] Please see Figure 5As shown, a water distribution plate 3 is fixed to the inner wall of the baffle 2; a water channel 32 is symmetrically opened in the middle of the water distribution plate 3; the water channel 32 is inclined; the water distribution plate 3 is located at the bottom of the spray pipe 15; part of the water mist sprayed from the atomizing nozzle 18 will reach the inner wall of the baffle 2. After these water mists come into contact with the baffle 2, they will liquefy into water droplets. Then the water droplets will flow along the inner wall of the baffle 2 and reach the surface of the water distribution plate 3. Then the water will flow out along the water channel 32, reducing the wastewater accumulated at the connection between the baffle 2 and the vertical plate 12, and reducing the corrosive effect of the wastewater on the vertical plate 12 and the baffle 2.

[0027] Please see Figure 4 and Figure 5 As shown, a first limiting plate 4 is symmetrically fixed to the inner side wall of the baffle 2; a second limiting plate 42 is symmetrically fixed to the middle of the water spray pipe 15; the first limiting plate 4 and the second limiting plate 42 are correspondingly arranged; when the water spray pipe 15 rotates under the meshing action of the sector gear 14 and the parallel gear 17, the water spray pipe 15 will bring the second limiting plate 42 closer to the first limiting plate 4. When the second limiting plate 42 and the first limiting plate 4 come into contact, they will apply resistance to the water spray pipe 15, causing the water spray pipe 15 to rotate quickly under the action of gravity, limiting the rotation amplitude of the water spray pipe 15, and reducing the excessive squeezing of the water inlet pipe 16 by the excessive rotation of the water spray pipe 15.

[0028] Please see Figure 4 and Figure 5 As shown, a plurality of first magnets 5 are fixedly attached to the surface of the first limiting plate 4; a plurality of second magnets 52 are fixedly attached to the surface of the second limiting plate 42; the first magnets 5 and the second magnets 52 are arranged correspondingly; when the second limiting plate 42 and the first limiting plate 4 are close together, the second magnets 52 and the first magnets 5 will also be close to each other, and the second limiting plate 42 will be subjected to the repulsive force between the first magnets 5 and the second magnets 52, so that the water spray pipe 15 will be subject to additional resistance when rotating upward, which will slow down the rotation speed of the water spray pipe 15, making the water mist distribution within the range more uniform and improving the dust suppression effect of the water mist on dust.

[0029] Please see Figure 4 As shown, multiple sponges 6 are fixed to the surface of the water spray pipe 15; the sponges 6 are arranged at equal intervals; when the water spray pipe 15 rotates, it will drive the sponges 6 to move together, and when the sponges 6 rotate, they will clean the inner wall of the upright plate 12, improve the cleanliness of the inner wall of the upright plate 12, and reduce the friction between the water spray pipe 15 and the upright plate 12 when it rotates.

[0030] Please see Figure 5 As shown, the baffle 2 has an arc-shaped structure; because the baffle 2 has an arc-shaped structure, the dust will quickly detach along the surface of the baffle 2 after reaching the surface of the baffle 2, reducing the amount of dust adhering to the surface of the baffle 2.

[0031] Working principle: The grab bucket moves to the top of the discharge hopper 1 and releases the material. Dust is generated as the material flows through the air. At this time, a high-pressure water jet mixed with air is sent along the water inlet pipe 16 to the spray pipe 15 via an air compressor, booster pump, or other equipment. The water jet is then sprayed out in a mist form through the atomizing nozzle 18. Simultaneously, the motor 13 is started, causing the sector gear 14 to rotate. The rotation of the sector gear 14 meshes with the flat gear 17, causing the flat gear 17 to drive the spray pipe 15 to rotate along the vertical plate 12. At this time, the angle of the atomizing nozzle 18 changes. When the sector gear 14 and flat gear 17 stop... When the gear is engaged, the water spray pipe 15 will reset under gravity, causing the angle of the sprayed water mist to continuously change until the sector gear 14 rotates back to engage with the flat gear 17, causing the water mist to spray up and down. This water mist will combine with dust in the air and cause it to settle, achieving dust suppression during the grab bucket loading process. The water mist sprayed from the atomizing nozzle 18 will be sprayed from the fixing hole 22. When the grab bucket loads the hopper 1, the material will diffuse under gravity, and some dust will flow onto the surface of the water spray pipe 15. At this time, the baffle 2 will block these materials. The water mist sprayed from head 18 reaches the inner wall of baffle 2. Upon contact with baffle 2, the water mist liquefies into droplets, which then flow along the inner wall of baffle 2 and reach the surface of water distribution plate 3. The water then flows out along water channel 32, reducing wastewater accumulation at the connection between baffle 2 and vertical plate 12. When the spray pipe 15 rotates under the meshing action of sector gear 14 and parallel gear 17, it brings the second limiting plate 42 closer to the first limiting plate 4. When the second limiting plate 42 contacts the first limiting plate 4, it applies resistance to the spray pipe 15, causing it to move rapidly. The water spray pipe 15 rotates under the action of gravity, which limits the rotation range of the water spray pipe 15. When the second limiting plate 42 and the first limiting plate 4 are close to each other, the second magnet 52 and the first magnet 5 will also be close to each other. The second limiting plate 42 will be subjected to the repulsive force between the first magnet 5 and the second magnet 52, which will cause the water spray pipe 15 to be subjected to additional resistance when rotating upward, thus slowing down the rotation speed of the water spray pipe 15 and making the water mist distribution within the range more uniform. When the water spray pipe 15 rotates, it will drive the sponge 6 to move together. When the sponge 6 rotates, it will clean the inner wall of the upright plate 12, improving the cleanliness of the inner wall of the upright plate 12.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
