Description

Technical Field

[0001] This utility model relates to the field of material loading and unloading equipment technology, specifically to a safe and environmentally friendly waste material recycling system outside a train loading station. Background Technology

[0002] Rapid quantitative loading stations play a crucial role in the efficiency of material transportation. In recent years, with the continuous strengthening of the domestic economy, distribution stations, ports, and wharves, whose main tasks are unloading, storing, loading, and transporting various bulk materials (coal, ore powder, coke, sand, gravel, grain, etc.), have developed significantly. Owners whose main business is coal logistics have a large number of customers, and the sources of goods from different customers cannot be mixed or blended. This presents challenges such as the varying origins, types, and qualities of materials unloaded and stored, and the requirement that the shipped bulk materials not contaminate each other.

[0003] Currently, due to loading process requirements, 10% to 20% of residual material remains in the buffer bin after each train is assembled. Currently, the residual material recovery operation involves trucks driving to the railway loading station and collecting the material at the bottom of the loading chute on the track bed. This method of residual material recovery has the following drawbacks: (i) The truck needs to cross several railway lines to pick up materials at the train loading point, which poses a significant safety risk to personnel and vehicles. According to the latest railway safety regulations, trucks are no longer allowed to drive onto the railway track bed for work. (ii) Frequent material receiving operations by automobiles over a long period of time will damage the track bed structure, causing deformation and displacement of the track, increasing the risk of train safety accidents. (iii) When a car enters the loading station of a train, it will occupy the train track, preventing the train from entering the track to load materials and affecting the operation of each train track; (iv) When changing materials at the loading station, some customers wash and clean the loading station's warehouse. The wastewater and dust from the washing process will pollute the track environment.

[0004] To ensure loading safety and efficiency, a safe and environmentally friendly waste material recycling system outside the train loading station is being researched to meet the urgent equipment needs of the industry. Utility Model Content

[0005] In view of the problems and shortcomings of the existing technology, this utility model provides a safe and environmentally friendly waste material recycling system outside the train loading station.

[0006] The technical solution of this utility model is as follows: First, the surplus material is transferred to another branch chute on one branch of the existing loading system. A flap device is installed between the forks of the branch chute. The surplus material is diverted to the surplus material guide chute of the new branch chute by flipping the flap. Then, it is transferred to the loading point outside the station by a feeder and conveyor. Finally, the surplus material is recycled by truck.

[0007] A safe and environmentally friendly waste material recycling system outside a train loading station includes a first branch chute located at the bottom of a quantitative silo at the train loading station, a second branch chute, a feeder, a conveyor, and a waste material recycling station. The second branch chute is connected to a branch of the first branch chute and has a local guide chute, a waste material guide chute, and a flap device. The local guide chute is arranged along a branch of the first branch chute and is used to transport materials to the loading chute of the original train loading station. The waste material guide chute is used to transport waste materials to the feeder below its outlet. The flap device is used to switch the opening and closing states of the local guide chute and the waste material guide chute. A conveyor is located downstream of the feeder, and the downstream of the conveyor is connected to the vehicle waste material recycling station. The vehicle waste material recycling station has an unloading chute, the outlet of which is located above the loading point.

[0008] The flipping device controls the flipping action through a driving element to switch the opening and closing states of the local guide chute and the surplus material guide chute.

[0009] The driving element is a hydraulic cylinder.

[0010] The second branch chute also includes an inspection door located at the top for periodic inspection and replacement of the flap device.

[0011] The feeder is a belt feeder with a dust suppression hood on top to reduce dust pollution during the transfer process.

[0012] The conveyor is a belt conveyor, supported by a closed truss to protect the belt from external environmental influences and extend its service life.

[0013] The unloading chute is a vertical telescopic unloading chute, which uses a separate electro-hydraulic actuator to control its vertical extension and retraction. The adjustment range is 3.3 meters to 4.5 meters to accommodate carriages of different heights.

[0014] The waste recycling station adopts a fully enclosed design to prevent dust from overflowing and meets environmental protection standards.

[0015] It also includes a PLC control system, which is used to control the power distribution, control, and monitoring functions of the hydraulic cylinders of the feeder, conveyor, and tipping device.

[0016] This utility model discloses a safe and environmentally friendly waste material recycling system outside a train loading station, which also includes a lighting system and a video monitoring system for real-time monitoring of the waste material transfer process.

[0017] The beneficial effects of this utility model are: Workers will no longer enter the tracks to work, and trucks will no longer enter the tracks to load surplus materials. The frequent running of trucks on the tracks will no longer cause deformation or breakage of the tracks, thus ensuring the structure of the track bed and reducing the safety risks to train operation and personnel.

[0018] Trucks no longer need to enter the area beneath the train loading station to operate, thus not occupying the railway track. Trains can then enter designated locations for loading operations more quickly, thereby improving loading efficiency. Waste material recycling is conducted independently outside the station, with a precise, smooth, and fast process, further improving waste material recycling efficiency.

[0019] The entire cleaning, collection, and transfer equipment is designed in a closed manner. It washes and cleans the independent loading station outside the railway station, ensuring that the washing wastewater and dust do not flow into the train track surface, and guaranteeing that the dust concentration in the loading operation area does not exceed the national environmental protection standards.

[0020] This system enables the safe and environmentally friendly recycling of surplus materials outside train loading stations, with a recycling capacity of 700-1000 tons per hour. The recycling rate can reach over 95% of the surplus materials within the original loading station. The system can be integrated with the original train loading station's loading control system to achieve automatic / semi-automatic operation of surplus material recycling, improving loading efficiency and reducing safety risks to personnel and vehicles.

[0022] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0023] Example This utility model aims to reduce safety risks by transferring surplus materials outside the loading station, preventing trucks from entering the tracks to transport surplus materials. At the same time, the entire cleaning, collection, and transfer equipment is designed in a closed manner to ensure that the dust concentration in the loading operation area does not exceed the national environmental protection standards, thus achieving the goal of safe and environmentally friendly recycling.

[0024] See Figure 1 A safe and environmentally friendly waste material recycling system for railway loading stations includes a first branch chute 1 located at the bottom of a quantitative silo at the railway loading station, a second branch chute 2, a feeder 3, a conveyor 4, and a waste material recycling station. The second branch chute 2 is connected to a branch of the first branch chute 1 and includes a local guide chute 21, a waste material guide chute 22, and a flap device 23. The local guide chute 21 is located along a branch of the first guide chute and is used to transport materials to the loading chute of the original railway loading station; the waste material chute is used to transport waste materials to the feeder 3 below its outlet; the flap device 23 is used to switch the opening and closing states of the local guide chute 21 and the waste material guide chute 22. A conveyor 4 is located downstream of the feeder 3, supported by a truss, and its downstream end is connected to the railway waste material recycling station. The railway waste material recycling station includes an unloading chute 5, the outlet of which is located above the loading point. The surplus material falls into the truck bed via the "surplus material guide chute 22 of the second branch chute 2 - feeder 3 - conveyor 4 - unloading chute 5", and is then transferred by truck.

[0025] The second branch chute 2, feeder 3, and conveyor 4 are all located in an enclosed space. At the same time, the newly established waste material recycling station also adopts a fully enclosed design to prevent dust from spilling into the public environment and to ensure that the surrounding environment of the operation meets environmental protection standards.

[0026] See Figure 2 The second branch chute 2 is located in the middle of one branch of the first branch chute 1, and is connected by flanges at the top and bottom for easy disassembly without damaging the original equipment. The second branch chute 2 also includes a drive element 24 and a maintenance door 25. The drive element 24 is a hydraulic cylinder used to control the tilting device 23 to open or close the residual material guide chute 22 or the local guide chute. Specifically, when the tilting device 23 tilts to the side of the local guide chute 21, the residual material guide chute 22 opens; when it tilts to the side of the residual material guide chute 22, the local guide chute 21 opens. The maintenance door 25 is located in the middle of the upper part of the second branch chute 2 for periodic inspection and replacement of the tilting device 23.

[0027] See Figure 3 The feeder 3 is a belt feeder 3, the conveyor 4 is a belt conveyor 4, and the unloading chute 5 is a vertical telescopic chute. The end of the conveyor 4 closest to the waste material recycling station is the head, which is located above the unloading chute.

[0028] Firstly, after the original materials at the train loading station are loaded, when it is necessary to replace them with other different types of materials, 10% to 20% of the material will remain in the buffer bin. This remaining material needs to be cleaned up to ensure the accuracy of the material transport. At this time, the vehicle transferring the remaining material arrives at the remaining material recycling station and is positioned. Simultaneously, the remaining material in the buffer bin falls through the buffer bin's flat gate into the quantitative bin, and then through the quantitative bin's flat gate into the first branch chute 1. Then, the hydraulic cylinder controls the flap device 23 to open, and the remaining material no longer falls into the original loading chute at the train loading station, but instead falls through the remaining material guide chute 22 into the feeder 3. The belt feeder 3 moves synchronously, transporting the remaining material to the lower conveyor 4. The belt conveyor 4 transports the remaining material from the tail end of the upstream to the remaining material recycling station at its head. Finally, the remaining material falls from the guide chute at the head of the conveyor 4 into the unloading chute 5, and finally falls into the transfer car, which transports it to the collection point. The entire remaining material recycling system process is completed. By opening and closing the flap, the material is diverted and redirected. The surplus material originally flowing to the loading station is diverted to a newly set surplus material recycling and loading point outside the loading station through the flap device 23 in the second branch chute 2.

[0029] The feeder 3 is selected based on the on-site working environment and space. It features simple installation, high operating efficiency, and can change the direction of residual material movement, effectively reducing the impact force of the falling residual material. The belt feeder 3 is equipped with a dust suppression hood 31, which effectively avoids dust pollution caused by the transfer of residual material and protects the working environment.

[0030] Belt conveyor 4 transfers surplus material from belt feeder 3 to the newly established loading point, enabling long-distance transport of surplus material. An enclosed truss is designed between the train loading station and the newly established surplus material recycling station to effectively protect the belt, reducing prolonged exposure to sunlight and rain, thus extending the belt's service life. Maintenance personnel can move freely within the enclosed truss, facilitating routine maintenance and repair of the belt.

[0031] See Figure 4 The newly established waste material recycling station includes a steel structure tower and unloading chutes. The steel structure tower is simple in structure, high in strength, low in cost, and occupies a small area. The unloading chutes are vertical telescopic chutes, controlled by separate electro-hydraulic actuators to extend and retract synchronously, allowing for height adjustment between 3.3 meters and 4.5 meters, suitable for different types of wagons. The loading point adopts a closed design to prevent dust from spilling into the public environment, ensuring the surrounding environment meets environmental standards.

[0032] This utility model's waste material recycling system also includes a PLC control system, as well as equipment such as a power distribution cabinet, PLC control cabinet, and local control box. The PLC control system provides centralized control, enabling power distribution, control, and monitoring of the hydraulic cylinders of the feeder 3, conveyor 4, and tilting device 23. The system has local / remote operation capabilities. In remote operation, the operator operates from the control room. When waste material needs to be cleared, the operator selects the tilting device open button, flipping the tilting device 23 to open the waste material guide chute 22. The material enters the feeder 3 through the waste material guide chute 22, is transported by the feeder 3 to the conveyor 4, and finally transported to the waste material recycling station. From there, it is loaded into a truck via a vertical telescopic chute for waste material recycling.

[0033] In addition, lighting and video surveillance systems were added to enable real-time monitoring of the surplus material transfer system, allowing the unloading situation to be observed at any time from the loading station control room.

[0034] This system can meet the needs of complex environments such as ports, mining areas, and transshipment stations, while also complying with national standards and regulations regarding railways, environmental protection, energy conservation, and safety. The initial investment in the equipment is low, and operating costs are minimal. After the owner changes the type of materials or the service customer, the time interval between loading and unloading at the loading station is reduced by 60%, shortening loading preparation time and potentially increasing daily loading capacity by 2-3 loads, thereby improving the customer's daily shipping capacity and economic benefits. The system is simple to maintain, highly automated, reduces the labor intensity of workers, and improves the working environment.

[0035] The above description represents a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
