Description

Technical Field

[0001] The present invention relates to the technical field of port loading, unloading and conveying, and more specifically, to an integrated self-adaptive anti-blocking funnel for unloading, screening and crushing of laterite nickel ore at ports. Background Art

[0002] As the main source of nickel metal extraction globally, laterite nickel ore is a clay and stone mixed ore formed by the long-term weathering, leaching and sedimentation of nickel oxide deposits. Affected by the environment and operation means, the water content of laterite nickel ore is relatively high, and small-sized ore powder and large-sized ore coexist, and it is very easy to cause equipment blockage during the conveying processes such as loading, unloading and transshipment.

[0003] The port ship-unloading funnel is a key equipment in the process of unloading laterite nickel ore ships, mainly used for receiving materials during port ship unloading. The ship-unloading funnel is generally conical, with a larger upper opening and a smaller lower opening. A grille with a certain size specification is arranged at the upper opening for buffering materials and screening large-sized stones and impurities. The laterite nickel ore is grabbed by a ship-unloading grab to directly above the grille and falls under the action of gravity, and is loaded into a truck or a belt line through the ship-unloading funnel and then transferred to the rear storage yard. Due to the relatively high water content of laterite nickel ore and the large viscosity of the material, the nickel ore adheres to each other and accumulates into groups when flowing, and it is very easy to adhere to the surface of the equipment, resulting in funnel blockage; in addition, under long-term operation, stones are likely to accumulate and jam at the funnel grille, causing arching, which hinders the nickel ore from falling into the funnel interior. Usually, workers are required to clean the grille. Therefore, the current ship-unloading funnel has obvious deficiencies in terms of automation degree, operation convenience and environmental protection, seriously affecting the operation efficiency of nickel ore ship unloading.

[0004] Chinese Patent (CN204689165U): A funnel applicable to the loading of laterite nickel ore. Aiming at the problems of small size of the blanking port of ordinary funnels, easy adhesion of materials to the hopper wall, and easy blockage of the outlet, the outlet of the funnel body is set as a rectangle, and two vertical baffle plates are added to the two long sides, and anti-collision soft pads are provided on the side of the baffle plates. On the one hand, this design is only applicable to the scenario of truck transportation and has certain limitations. On the other hand, this design only solves the problem of material blockage by changing the shape of the outlet. When facing materials mixed with clay and large stones, it is still easy to block, and at the same time, it is difficult to fill the truck carriage, resulting in low transfer efficiency. Chinese Patent (CN107487553A): A large funnel for a ship unloader. Aiming at problems such as easy blockage of the funnel, a grille is provided at the top of the funnel, and several vibrators are symmetrically arranged on the outer wall of the funnel. This design can solve the problem of funnel blockage to a certain extent. Through vibration, the materials adhered to the wall can be shaken off. However, laterite nickel ore is a mineral mixed with clay and stones, and the stones are easy to get stuck in the grille holes, causing material accumulation and arching and being difficult to remove. Chinese Patent (CN221680179U): A bulk cargo ship unloading and loading funnel. Aiming at problems such as high cost of material crushing and screening, a screen and a crusher are designed inside the funnel body. The screen is conical with openings at both the upper and lower ends, and the lower end of the screen is connected to the feed inlet of the crusher. This design uses the screen to screen the materials entering the funnel, so that the materials with particle sizes meeting the standards are screened out. Since the treatment is carried out inside the funnel, there is no material spillage and less loss. However, for materials with strong viscosity such as laterite nickel ore, the conical screen design is not convenient for its blanking, and a large amount of nickel ore will accumulate above the crusher and be difficult to crush. Chinese Patent (CN113019924A): A funnel with a pre-screening function. Aiming at problems such as easy blockage of the screen and low screening efficiency, a screening plate and a screening net are newly added above the funnel. The large-inclination screening plate can pre-screen most of the powdery sticky materials and qualified materials. Since the screening plate has a large inclination and is above the screen, the materials still have a large inertial impact on the screen after passing through the screening plate, avoiding screen blockage. However, there are a large number of stones mixed in the nickel ore. The stones exceeding the size will accumulate under the screen when impacting the screen, and some stones will even get stuck in the screen holes and be difficult to clean, seriously affecting the subsequent screening and blanking process.

[0021] Implementing the integrated adaptive anti-blocking funnel for red soil nickel ore port ship unloading, screening and crushing of the present invention has the following beneficial effects:

[0022] 1. The present invention adds a screening device above the traditional funnel to pre-separate large stones in the red soil nickel ore, which can reduce the risk of material blockage during the blanking process of the funnel and reduce the cleaning difficulty. The screening device is fed by the feeding chain plate, and the feeding chain plate can adjust the feeding speed through visual monitoring feedback, avoiding the accumulation and blockage of red soil nickel ore in the funnel under high-speed unloading of large flow, realizing the buffer and flow control of the funnel feeding, and improving the stability of the funnel; at the same time, the feeding chain plate is in a relatively open space, which is easier to clean and maintain in case of failure compared with the traditional direct feeding method. The two groups of rollers in the screening device are arranged in a V shape, and this structure can avoid the accumulation of ore soil on both sides and solve the cleaning problem. For the screening efficiency problem of red soil nickel ore, the rotational speed and spacing of the screening roller can be adjusted; for the blockage of red soil nickel ore on the roller and the problem of stuck stones, the screening roller can be reversed briefly and trigger the high-pressure water pump to clean at a fixed point. At the same time, the above devices are automatically adjusted by the control system according to the monitoring feedback, which is more efficient and safe than the traditional manual operation form;

[0023] 2. The present invention designs an integrated device for screening and crushing red soil nickel ore. Compared with the traditional crusher, it separates large-sized stones from viscous ore soil in the screening device, greatly reducing the ore soil content during the crushing process, making it easier for the roller teeth to feed and crush the stones; at the same time, there is no accumulation and restriction of ore soil around the stones, and the crushing angle can be adjusted as the roller teeth rotate, with a greater crushing probability; in addition, sensors are arranged on the roller teeth for pressure monitoring and feedback, and the rotational speed can be adaptively adjusted according to the crushing situation. For the situation of stuck stones and material blockage during crushing, the system can automatically adjust the posture of the high-pressure water pump to clean at a fixed point, reducing the risk of manual operation and improving the crushing efficiency;

[0024] 3. The bypass chute arranged in the present invention can ensure that the crushed stones enter the blanking hopper and are mixed with the ore soil. The system can control the operation of the vibration motor and the outlet valve according to the monitoring data inside the chute. The vibration motor is used to remove the laterite nickel ore adhered to the wall surface and reduce the risk of blockage inside the pipe. The valve at the outlet of the chute can control the flow rate of the laterite nickel ore, ensure the uniform flow rate of the nickel ore on the conveyor belt. At the same time, the mixed material can effectively avoid damage caused by the direct impact of stones on the belt, extend the service life of the belt, and reduce the equipment maintenance cost;

[0025] 4. Based on the closed-loop control of multi-sensor fusion, the present invention realizes the full-process automatic monitoring and dynamic adjustment of the screening and crushing of laterite nickel ore. The system can identify the distribution of laterite nickel ore blocks and the risk of blockage in real time through an industrial camera, and jointly build an accurate decision-making model with a pressure sensor to adaptively adjust the spacing of the screening rollers, the rotation speed of the crusher and the feeding speed, so as to improve the screening efficiency; A multi-level anti-blocking mechanism is set up, and the screening rollers are reversely rotated for a short time, the high-pressure water pump is used for fixed-point cleaning and the vibration motor cooperate to improve the anti-blocking efficiency. The system realizes the intelligent operation and maintenance of "self-treatment of blockage - self-optimization of parameters - self-diagnosis of faults", effectively reduces the risk of material blockage during the unloading of laterite nickel ore at the port, improves the unloading efficiency, and maximally guarantees the safety of operators.

The hydraulic cylinder 22 controls the opening angle of the scissor mechanism 20 to drive the gearbox 17 and the screening rollers 5 to move, so as to realize the adjustment of the roller spacing of the screening rollers 5.

[0042] In a preferred embodiment of the present invention, the feeding chain plate 2 is electrically connected to the feeding chain plate motor 1, and the feeding chain plate motor 1 is arranged on the side of the feeding device baffle 3. Above the feeding chain plate 2 is the feeding port, where the ship unloader grabs materials and discharges them. The feeding chain plate 2 is driven by the feeding chain plate motor 1 and can control the feeding speed according to the system feedback to avoid the occurrence of material blockage caused by continuous large-scale feeding. The screening rollers 5 and the gearbox 17 are both electrically connected to the servo motor 19, and the servo motor 19 is arranged at the end of the screening rollers 5. The roller crusher 10 is electrically connected to the crusher motor 9, and the crusher motor 9 is arranged on the side of the roller crusher 10. The chute outlet valve 14 is electrically connected to the valve motor 13, and the valve motor 13 is arranged at the end of the discharge port 15. Two groups of screening rollers 5 are arranged inside the feeding device baffle 3, and the ends of the two groups of screening rollers 5 are arranged in a V shape for nickel ore screening. The crusher funnel 7 and the blanking funnel 18 are horizontally arranged, and the blanking funnel 18 is arranged near the feeding chain plate 2 and away from the feeding chain plate. The feeding chain plate 2 is arranged on the left side of the screening rollers 5, and the right side of the screening rollers 5 is empty and the lower end is provided with the crusher funnel 7. An industrial wide-angle camera 24 is arranged at the upper end of the crusher funnel 7, and the industrial wide-angle camera 24 respectively covers the material conditions above the screening rollers 5, the roller crusher 10 and inside the bypass chute 12.

[0043] The working principle of the present invention is as follows:

[0044] Under the action of the feeding chain plate 2, the nickel ore is sent to the top of the screening device for separation. The screening roller 5 rotates, the ore soil falls through the roller gap and enters the material drop hopper 18, and the large stones continue to roll into the crusher hopper 7. Under the action of the screening roller 5, a large amount of sticky ore soil on the surface of the stone has been screened out. At the same time, the system will make real-time decisions based on the image data transmitted by the camera, judge the size of the material stone, and adjust the roller spacing of the screening roller 5. The roller spacing of the screening roller 5 is controlled by the scissor mechanism 20, and the gear box 17 is driven by the hydraulic pump 21 and the hydraulic cylinder 22 to move horizontally along the guide rail 16. When it is recognized that the material flow above the screening roller 5 exceeds the threshold, the system issues an instruction to reduce the speed of the feeding chain plate 2; when an oversized stone is detected, the system issues an instruction to suspend the operation of the feeding chain plate 2 and alarm; when stone blocking is detected, the corresponding screening roller 5 is triggered to reverse for a short time and the high-pressure water pump 4 is flushed at a fixed point.

[0045] Due to the lack of the influence of sticky minerals, the roller crusher 10 will be smoother when crushing stones. On the one hand, stones without mineral soil are easier to eat; on the other hand, there is no large amount of nickel ore piled up on the stones. When crushed, the stones can change their eating posture by jumping, making the probability of eating more likely. At the same time, the pressure sensor 8 feeds back pressure data to the system in real time, and reduces the speed of the crushing roller when the pressure exceeds the safety value; when the material is identified as stuck or blocked, the high-pressure water pump 4 is triggered for fixed-point flushing.

[0046] After the stones are broken, they flow into the material hopper 18 through the bypass chute 12 and mix with the ore soil before flowing out from the discharge port 15, which can prevent the stones from directly impacting the belt and causing damage. At the same time, the camera inside the bypass chute 12 feeds back the nickel ore flow and stickiness in the chute. When the flow is too large, the opening of the chute outlet valve 14 is appropriately reduced; when the laterite nickel ore is seriously sticky, the vibration motor 11 is triggered to clean the sticky ore soil on the surface through vibration.

[0047] The data collected by the industrial wide-angle camera 24 and the pressure sensor 8 are updated in real time on the monitoring screen. The system makes a comprehensive assessment of the screening and crushing efficiency of the equipment based on the collected data. When the efficiency is low, the motor is triggered to adjust the speed of the screening roller 5 and the distance between the rollers.

[0048] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
