Description

Technical Field

[0001] This invention relates to the field of loading and unloading equipment technology, specifically a combined dust removal hopper for loading and unloading at a dock. Background Technology

[0002] Loading and unloading at the dock is a crucial link in the logistics transportation of bulk materials (such as coal, ore, grain, cement, sand and gravel). The main function of its core equipment, the "hopper," is to temporarily store and guide bulk materials that have been stored or transported, and then accurately unload them into transport vehicles such as trucks, trains, and containers.

[0003] When loading and unloading materials at the dock, the materials need to be first transported into the hopper, and then loaded onto the trucks according to the requirements. When conveying materials with a high dust content into the hopper, water mist needs to be sprayed from the top of the hopper to suppress dust in order to accurately observe the accumulation height of the materials in the hopper. Because the water mist sprayed from the atomizing nozzle will flow and diffuse, the water mist intensity is low near the nozzle and weak far from the nozzle. When the materials are being transported and there is a strong wind, the wind flow can easily blow away and destroy the sprayed water mist barrier, which can easily cause dust to overflow and escape during unloading. This affects the accuracy of the staff's observation of the accumulation in the hopper, leading to overloading or underloading. It also affects the accuracy of subsequent loading and unloading and the environmental protection of the surrounding environment. Summary of the Invention

[0004] The purpose of this invention is to provide a combined dust removal hopper for loading and unloading materials at a dock, so as to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This invention is a combined dust removal hopper for loading and unloading materials at a dock, comprising a main body, with support platforms fixedly connected to the left and right sides of the main body, and further comprising;

[0007] The dust suppression mechanism is installed inside the main body and is used to remove dust during loading and unloading.

[0008] The auxiliary mechanism is installed on the side wall of the dust suppression mechanism to prevent water mist from mixing during spray dust suppression.

[0022] Furthermore, the loading and unloading assembly includes a conveying pipe fixedly connected to the outer surface of the water storage tank, and a connecting pipe fixedly connected to the end of the conveying pipe away from the water storage tank, and the connecting pipe fixedly connected to the outer wall of the funnel.

[0023] The connecting pipe is C-shaped.

[0025] The limiting component includes a spring rod that slides through the interior of the L-tube, an auxiliary spring that is fixedly connected to the side wall of the spring rod, and the elastic end of the auxiliary spring that is fixedly connected to the side wall of the L-tube.

[0026] One of the L-tubes has a spring disc fixedly connected to the top inner wall.

[0027] Furthermore, the sliding assembly includes a fixed bracket fixedly connected to the end of the spring rod away from the L-tube, and a hollow disc fixedly connected to the end of the fixed bracket away from the spring rod. Both hollow discs are slidably connected to the outer surface of the water inlet pipe.

[0028] Several atomizing nozzles are fixedly connected to the end of the hollow disc away from the fixed frame, and flexible hoses are fixedly connected to the bottom of the two fixed frames;

[0029] The end of the hose furthest from the hollow disc is fixedly connected to the side wall of the inlet pipe, and the inlet pipe is connected to the two hollow discs through the hose.

[0030] The diameter of the hollow disc on the side closest to the fixed frame is larger than the diameter of the inner wall of the hollow disc.

[0031] Furthermore, the active component includes a movable disk that is slidably connected inside the hollow disk, an auxiliary ring that is fixedly connected to the side of the movable disk near the fixed frame, and several flip plates that are rotatably connected to the outer surface of the auxiliary ring.

[0032] The side wall of the movable plate has several water outlet holes;

[0033] The translation component includes a second spring rod that slides through the left and right outer walls of the hollow disk, and an inclined block is fixedly connected to the outer surface of the second spring rod located outside the hollow disk.

[0034] Furthermore, a tension spring is fixedly connected to the outer surface of the spring rod 2 inside the hollow disk, and the end of the tension spring away from the spring rod 2 is fixedly connected to the inner wall of the hollow disk.

[0035] The sidewall of the semicircular plate is fixedly connected to two flexible layers. The sidewall of the flexible layers is fixedly connected to the outer surface of the hollow disk. The sidewall of the semicircular plate has several circular holes.

[0036] Furthermore, a linear spring is fixedly connected to the side wall of the limiting block;

[0037] The moving component includes a long rod that slides through the side wall of the limiting block, and two long rods are fixedly connected to a ring on one side near the middle of the funnel;

[0040] The auxiliary components include a fixing ring fixedly connected to the side wall of the second L-tube, and several flip plates are rotatably connected to the inner wall of the fixing ring. A bending spring is fixedly connected to the side wall of the flip plate, and the end of the bending spring away from the flip plate is fixedly connected to the inner wall of the fixing ring.

[0041] The present invention has the following beneficial effects:

[0042] 1. This invention, through the limiting component and the sliding component, when the two hollow discs slide alternately and spray water mist, the alternating spraying of water mist can prolong the water mist intensity during spraying and form a relay barrier. By prolonging the atomization intensity of the water mist spraying, the water mist barrier can be reduced from being blown away and destroyed by external wind, thus preventing some dust from overflowing and escaping. Through effective dust control, workers can clearly observe the accumulation height of materials in the funnel when putting materials into it, reducing the possibility of overloading or underloading due to dust overflow, thereby improving the accuracy of conveying during subsequent loading and unloading.

[0043] 2. This invention, through the shaking component and the sliding component, reduces the force exerted on the atomizing nozzle when spraying water from the outlet in the opposite direction. This reduces the reaction force generated when the pressure of the atomizing nozzle is high, which can cause the hollow disc to have difficulty sliding stably to its farthest position. This ensures that the hollow disc and the spring rod can slide stably while increasing the coverage area of ​​the water mist when the atomizing nozzle sprays water, thereby ensuring the stability of the hollow disc during sliding spraying and improving the dust removal efficiency during dust suppression.

[0044] 3. In this invention, the rotation of multiple rotating plates can guide the water mist sprayed from the first hollow disc outward, reducing the collision between the water mist sprayed from the first hollow disc and the water mist sprayed from the second hollow disc when it moves the moving disc to reset. This also reduces the collisions that occur when the two hollow discs alternate spraying, which can lead to a decrease in local water mist concentration and spraying force, making it difficult to form a uniform water mist barrier. This further increases the coverage area of ​​the water mist cloud while ensuring atomization intensity and unloading efficiency.

[0045] 4. In this invention, through the translation and sliding components, when water spraying is no longer performed after loading and unloading, since no water flow enters the hollow disc, the semi-circular plate will reset under the contraction potential energy of the tension spring. At this time, the flexible layer will squeeze the gas in the cavity formed. When the gas is squeezed, it will be sprayed through several round holes onto the side wall of the atomizing nozzle, thereby reducing the situation where water droplets remain on the side of the atomizing nozzle when spraying water. By cleaning the residual water droplets, the formation of dust from the material being loaded into the funnel and the mixing of the water droplets can be reduced, causing the atomizing nozzle to become clogged. This ensures the stable spraying of the subsequent atomization pattern and improves the continuity of spraying when loading and unloading materials.

[0046] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0063] Please see Figures 1-12 As shown, the present invention is a combined dust removal hopper for loading and unloading at a dock, comprising a main body 1, with support platforms 101 fixedly connected to the left and right sides of the main body 1, and further comprising;

[0065] Auxiliary mechanism 3 is installed on the side wall of dust suppression mechanism 2 to prevent water mist from mixing during spray dust suppression;

[0066] Among them, the dust suppression mechanism 2 can reduce the uneven spray caused by water mist collision during the loading and unloading of the main body 1 by using the auxiliary mechanism 3 to reduce the dust suppression mechanism 2 working.

[0067] Entity 1 includes:

[0068] Loading and unloading assembly 11 is installed inside the main body 1 via a carrier component;

[0069] The support includes a funnel 111 rotatably connected to the top of the main body 1, and a water storage tank 112 is provided on the side wall of the funnel 111. The water storage tank 112 is fixedly connected to the side wall of one of the support platforms 101.

[0070] The dust suppression mechanism 2 includes several water inlet pipes 201 disposed inside the funnel 111. The dust suppression mechanism 2 includes:

[0071] Restriction component 21 is installed on the side wall of water inlet pipe 201 by means of fasteners;

[0072] Sliding component 22 is mounted on the side wall of limiting component 21;

[0073] Shaking component 23 is installed inside sliding component 22;

[0074] Translation component 24 is mounted on the side wall of sliding component 22;

[0075] The fasteners include two L-tubes 211 fixedly connected to the top outer wall of the water inlet pipe 201. The bottom outer wall of the L-tube 211 has a round hole. The first L-tube 211 has a counterweight 212 slidably connected inside. The bottom of the counterweight 212 is fixedly connected to a circular piece 213.

[0076] Auxiliary mechanism 3 includes a limiting block 301 fixedly connected to the outer walls of the left and right sides of the water inlet pipe 201. Auxiliary mechanism 3 includes:

[0077] The movable component 31 is slidably disposed on the side wall of the water inlet pipe 201;

[0078] Auxiliary component 32 is installed on the side wall of water inlet pipe 201.

[0079] The loading and unloading assembly 11 includes a conveying pipe 113 fixedly connected to the outer surface of the water storage tank 112. A connecting pipe 114 is fixedly connected to one end of the conveying pipe 113 away from the water storage tank 112. The connecting pipe 114 is fixedly connected to the outer wall of the funnel 111.

[0080] The connecting pipe 114 is C-shaped. First, an electric opening and closing device is installed at the bottom of the funnel 111. At the same time, a detection sensor is installed on the outside of the funnel 111 to detect the trajectory when material is loaded into the funnel 111. Then, the conveying pipe 113 is connected to the external pump device.

[0081] An inclined plate is fixedly connected inside the water inlet pipe 201, and one end of the water inlet pipe 201 near the connecting pipe 114 is fixedly connected to the connecting pipe 114.

[0082] The limiting component 21 includes a spring rod 214 that slides through the interior of the L-tube 211. An auxiliary spring is fixedly connected to the side wall of the spring rod 214, and the elastic end of the auxiliary spring is fixedly connected to the side wall of the L-tube 211.

[0083] One of the L-tubes 211 has a spring disc 215 fixedly connected to the top inner wall.

[0084] The sliding assembly 22 includes a fixed frame 221 fixedly connected to the end of the spring rod 214 away from the L-tube 211. A hollow disc 222 is fixedly connected to the end of the fixed frame 221 away from the spring rod 214. Both hollow discs 222 are slidably connected to the outer surface of the water inlet pipe 201.

[0085] A number of atomizing nozzles 223 are fixedly connected to one end of the hollow disc 222 away from the fixed frame 221, and hoses 224 are fixedly connected to the bottom of the two fixed frames 221;

[0086] Among them, the end of the hose 224 away from the hollow disc 222 is fixedly connected to the side wall of the water inlet pipe 201, and the water inlet pipe 201 is connected to the two hollow discs 222 through the hose 224;

[0087] The diameter of the hollow disc 222 near the fixed frame 221 is larger than the diameter of the inner wall of the hollow disc 222. When water inside the water storage tank 112 is transported to the inside of the water inlet pipe 201, some water will be blocked by the inclined plate inside the water inlet pipe 201 and enter between the hollow disc 222 and the moving disc 231 through the hose 223. When the water flow continues to enter, it will be sprayed outward through multiple atomizing nozzles 223. At the same time, some water will flow to the area behind the inclined plate due to the obstruction of the inclined plate.

[0088] The active component 23 includes a movable disk 231 that is slidably connected inside the hollow disk 222. An auxiliary ring is fixedly connected to the side of the movable disk 231 near the fixed frame 221. Several flip plates 232 are rotatably connected to the outer surface of the auxiliary ring.

[0089] The side wall of the movable plate 231 has several water outlet holes;

[0090] The translation component 24 includes a spring rod 241 that slides through the left and right outer walls of the hollow disk 222. An inclined block is fixedly connected to the outer surface of the spring rod 241 outside the hollow disk 222. When the moving disk 231 is pushed by the continuous flow of water, the moving disk 231 will slide inside the hollow disk 222. When the moving disk 231 slides, it will drive the auxiliary ring and several flip plates 232 to slide synchronously.

[0091] A tension spring is fixedly connected to the outer surface of the spring rod 241 located inside the hollow disk 222. The end of the tension spring away from the spring rod 241 is fixedly connected to the inner wall of the hollow disk 222.

[0092] Two flexible layers 243 are fixedly connected to the side wall of the semicircular plate 242. The side wall of the flexible layer 243 is fixedly connected to the outer surface of the hollow disk 222. Several circular holes are opened on the side wall of the semicircular plate 242. When the inclined block is pushed by the auxiliary ring, the inclined block will drive the spring rod 241 to slide. At this time, the tension spring on the spring rod 241 will be in a compressed state. Since the position of the middle area of ​​the flexible layer 243 is fixedly connected to the side wall of the hollow disk 222, when the spring rod 241 slides, it will push the semicircular plate 242 to slide.

[0093] A linear spring is fixedly connected to the side wall of the limiting block 301;

[0094] The moving component 31 includes a long rod 311 that slides through the side wall of the limiting block 301, and a ring 312 is fixedly connected to one side of the two long rods 311 near the middle of the funnel 111.

[0095] A conical ring 313 is fixedly connected to the end of the two long rods 311 away from the circular ring 312;

[0096] The linear spring is fixedly connected to the side wall of the ring 312 at one end;

[0097] The auxiliary component 32 includes a fixed ring 321 fixedly connected to the side wall of the second L-tube 211. Several flip plates 322 are rotatably connected to the inner wall of the fixed ring 321. A bending spring is fixedly connected to the side wall of the flip plates 322. The end of the bending spring away from the flip plates 322 is fixedly connected to the inner wall of the fixed ring 321. When the multiple flip plates 322 rotate inside the fixed ring 321, a cone-like state is formed between the multiple flip plates 322. At the same time, after the multiple flip plates 322 rotate, they can be in an inclined state in front of the first hollow disk 221.

[0098] In use, an electric opening and closing device is first installed at the bottom of the funnel 111, and a detection sensor is installed on the outside of the funnel 111 to detect the trajectory of materials being loaded into the funnel 111. Then, the conveying pipe 113 is connected to the external pump. When materials are conveyed into the funnel 111, the external pump is started. During the conveying process, the pump will transport the water source inside the water storage tank 112 through the conveying pipe 113 and the connecting pipe 114 to the water inlet pipe 201. When the water flows into the water inlet pipe 201, some of the water will enter the two hollow discs 222 through the hose 224. When the water flows into the hollow discs 222, it will be atomized and sprayed outward through several atomizing nozzles 223 on the side wall, thereby achieving the purpose of dust suppression during loading and unloading. When loading and unloading are required, the vehicle to be loaded is parked at the bottom of the funnel 111 and the opening and closing device at the bottom of the main body 1 is opened, so that the materials flow into the loading vehicle, achieving the purpose of loading and unloading.

[0099] When water from the storage tank 112 is delivered to the inlet pipe 201, some water is blocked by the inclined plate inside the inlet pipe 201 and enters between the hollow disc 222 and the moving disc 231 through the hose 224. As the water continues to flow in, it is sprayed outward through multiple atomizing nozzles 223. At the same time, some water flows to the area behind the inclined plate due to the obstruction of the inclined plate. When water enters the inlet pipe 201, it enters the L-tube 211 through the open state of the counterweight 212 and the disc 213 inside the first L-tube 211 and pushes the spring rod 214 to slide during subsequent entry. When the spring rod 214 inside the first L-tube 211 slides, it pushes the fixed bracket 221 and the hollow disc 222 connected to it. 2. This causes the hollow disc 222 to slide while the atomizing nozzle 223 sprays atomized water mist. Subsequently, as the water continues to flow into the inlet pipe 201, the disc 213 and the counterweight 212 are forced to close due to the changes in the flow velocity and pressure of the water entering. The closure between the disc 213 and the L-tube 211 causes the water flow inside the inlet pipe 201 to stop. Then, when subsequent water flows into the inlet pipe 201, it pushes the water flow into the second L-tube 211 and pushes open the spring disc 215, similar to a water hammer effect. Subsequently, when the water flows into the other L-tube 211, it pushes the spring rod 214 inside the other L-tube 211 and drives the hollow disc 222 connected to it. As the water slides forward, when some of the water pushes the spring disc 215 into another spring rod 214, the water flows out through the round hole at the bottom while pushing the spring rod 214. At this time, the pressure inside the inlet pipe 201 decreases, and the disc 213 inside the first L-tube 211 slides downward under the weight of the counterweight 212, allowing new water to enter the first L-tube 211 and repeating the above process. Simultaneously, when water enters one L-tube 211 while the other L-tube 211 is closed, as some of the water pushes the spring rod 214 out through the round hole, the closed spring rod 214, under the elasticity of the auxiliary spring, will cause the connected hollow disc 222 to reset. This allows... The two hollow discs 222 slide back and forth on the surface of the water inlet pipe 201 in an alternating manner. When the two hollow discs 222 slide alternately and spray water mist, the alternating spraying of water mist can prolong the water mist intensity and form a relay barrier. By prolonging the atomization intensity of the water mist spraying, the water mist barrier can be reduced from being blown away and destroyed by external wind, thus preventing some dust from overflowing and escaping. Through effective dust control, the staff can clearly observe the accumulation height of the material in the funnel 111 when putting materials into the funnel 111, reducing the situation of overloading or underloading due to dust overflow, thereby improving the accuracy of conveying during subsequent loading and unloading.

[0100] When water flows through hose 224 between hollow disc 222 and moving disc 231, the continuous inflow of water causes it to atomize and spray outward through atomizing nozzle 223, simultaneously generating a pushing force on moving disc 231. As moving disc 231 is pushed by the continuous inflow of water, it slides within hollow disc 222. This sliding motion causes the auxiliary ring and several tilting plates 232 to slide synchronously. When moving disc 231 is not sliding, the tilting plates 232 are in a hollow position inside hollow disc 222. When the hollow disc 222 has a small aperture, the outer wall of the tilting plate 232 will be blocked by the inner wall of the small aperture of the hollow disc 222. At this point, the water flow will not flow out through the outlet hole on the moving disc 231. However, as the water flow continues to enter between the hollow disc 222 and the moving disc 231, pushing the moving disc 231 to the edge of the large aperture of the hollow disc 222, the outer wall of the tilting plate 232 will no longer be blocked by the inner wall of the small aperture of the hollow disc 222. At this point, the water flow can then push open the tilting plate 232 and spray out through the outlet hole on the moving disc 231. The water flow sprayed through multiple outlets generates a reverse force while the atomizing nozzles 223 spray water. This reaction force reduces the backward force generated by the atomizing nozzles 223. Simultaneously, as the water flow passes through the outlet and pushes open the tilting plates 232, the multiple tilting plates 232 form an inwardly tilted guide on the outer wall of the outlet. This guides the water flow towards the inlet pipe 201, reducing outward diffusion. When water mist sprayed from the atomizing nozzle 223 collides with the water, the force exerted by the reverse water flow from the outlet on the atomizing nozzle 223 is reduced. This reduces the reaction force generated when the water pressure from the atomizing nozzle 223 is high, which could cause the hollow disc 222 to have difficulty sliding stably to its farthest position. This ensures that the hollow disc 222 and the spring rod 214 can slide stably, while increasing the coverage area of ​​the water mist when the atomizing nozzle 223 sprays water. This ensures the stability of the hollow disc 222 during sliding spraying and improves the dust removal efficiency during dust suppression.

[0101] When some of the water inside the second hollow disc 222 is sprayed out through multiple water outlets on the movable disc 231, the water sprayed from the outlets impacts the side wall of the ring 312. The force of the water spraying from the outlets causes the ring 312 to slide along the long rod 311, pushing the conical ring 313. As the conical ring 313 slides, its inclined surface pushes the side walls of the multiple rotating plates 322, causing the multiple rotating plates 322 to rotate inside the fixed ring 321. When the multiple rotating plates 322 rotate inside the fixed ring 321, they form a cone-like shape. Simultaneously, after rotating, the multiple rotating plates 322 can move within the first hollow disc 222. The front is tilted. When the second hollow disc 222 resets and the first hollow disc 222 slides, the rotation of multiple flip plates 322 can guide the water mist sprayed by the first hollow disc 222 outward. This reduces the collision between the water mist sprayed by the first hollow disc 222 and the water mist sprayed when the second hollow disc 222 drives the moving disc 231 to reset. It also reduces the collision when the two hollow discs 222 spray alternately, which can cause a decrease in local water mist concentration and spray force, making it difficult to form a uniform water mist barrier. This further improves the coverage area of ​​the water mist cloud while ensuring atomization intensity and unloading efficiency.

[0102] When water flows into the hollow disk 222 and between it and the movable disk 231, pushing the movable disk 231 to slide, the movable disk 231 will drive the auxiliary ring and multiple flip plates 232 to slide synchronously. When the movable disk 231 drives the auxiliary ring to slide, the sliding of the auxiliary ring will push the inclined surface of the inclined block on the spring rod 241. When the inclined block is pushed by the auxiliary ring, the inclined block will drive the spring rod 241 to slide. At this time, the tension spring on the spring rod 241 will be in a compressed state. Since the position of the middle area of ​​the flexible layer 243 is fixedly connected to the side wall of the hollow disk 222, when the spring rod 241 slides, it will push the semicircular plate 242 to slide. When the semicircular plate 242 slides, it will pull the flexible layer 243, so that a cavity is formed between the flexible layer 243 and the semicircular plate 242. At the same time, in the semicircular plate 242... During the sliding and cavity formation process, the flexible layer 243, after being stretched, can absorb external gas through several round holes on the semicircular plate 242. When the loading and unloading is completed and water spraying is no longer performed, since no water flow enters the hollow disc 222, the semicircular plate 242 will reset under the contraction potential energy of the tension spring. At this time, the flexible layer 243 will squeeze the gas in the cavity formed. When the gas is squeezed, it will be sprayed through several round holes onto the side wall of the atomizing nozzle 223, thereby reducing the situation where water droplets remain on the side of the atomizing nozzle 223 when spraying water. By cleaning the residual water droplets, the formation of dust from the material loaded into the funnel 111 and the mixing of water droplets can be reduced, causing the atomizing nozzle 223 to become clogged. This ensures the stable spraying of the subsequent atomization pattern and improves the continuity of spraying when loading and unloading materials.

[0103] Compared to the traditional method of directly installing one or more equidistant atomizing nozzles, the alternating atomization spraying of water by two L-tubes 211 can dynamically change the spray position. During the sliding process, the spray area will form a continuous, dynamic and uniform coverage area as the L-tubes 211 slide and reset, which can dynamically fill the area blown away by the wind.
