Abstract
Description
Technical Field
[0001] This invention relates to a towed, environmentally friendly, quantitative coke loading equipment and method, which is a loading machinery, a loading system and loading process method for mechanically and automatically loading coke. Background Technology
[0002] Automated truck loading stations can accurately weigh bulk materials such as coal and grain and quickly load them into trucks, making them a highly efficient and commercially viable automated loading system. Coke, however, is a material that is easily broken into powder and has poor flowability, generating dust during loading and unloading, resulting in low efficiency. Traditional automated loading stations, typically equipped with buffer bins, weighing bins, and chutes, are prone to blockages and stagnation at the junctions of these components. Because coke is easily broken, the resulting powder disperses and spreads dust during loading, impacting the environment. Therefore, reducing blockages and minimizing dust impact during automated coke loading is a problem that needs to be addressed. Summary of the Invention
[0003] To overcome the problems of existing technologies, this invention proposes a towed, environmentally friendly, quantitative coke loading equipment and method. The system and method, addressing the fragile and poor flowability of coke, reduce the drop height of the coke, use ground weighing, employ a towed vehicle loading method, and utilize a dust collection system with enclosures, thus maintaining rapid and clean coke loading and reducing coke breakage.
[0004] The objective of this invention is achieved as follows: A towed, environmentally friendly, quantitative coke loading equipment includes: a steel frame, from top to bottom, a belt conveyor head, a hopper, a discharge arc gate, a telescopic chute, and a swing anti-breakage gate; the swing anti-breakage gate has a material-cutting gate at its end; the lower part of the steel frame is equipped with a closed dust cover with a dust removal device; both ends of the closed dust cover have automatic entry doors and automatic exit doors; the ground inside the closed dust cover is equipped with a vehicle towing device and a floor scale from top to bottom; the floor scale is electrically connected to a controller; the controller is electrically connected to the dust removal device, the belt conveyor, the material level indicator in the hopper, the discharge arc gate, the telescopic chute, the swing anti-breakage gate, the material-cutting gate, and the vehicle towing device.
[0005] Furthermore, the dust removal device is located on top of the enclosed dust cover and includes a dust suction hood, which is connected to the dust collector via a pipe.
[0006] Furthermore, the material interception arc gate includes: a gate channel, an arc gate shaft at the bottom of the material interception arc gate channel, the arc gate shaft being installed horizontally, the central axis of the arc gate shaft being perpendicular to the vehicle running direction, and a swing rod driven by a hydraulic cylinder or hydraulic motor to swing around the arc gate shaft on the arc gate shaft, the swing rod being fixedly connected to the arc gate plate.
[0007] Furthermore, the telescopic chute includes a fixed cylinder installed below the material discharge arc gate, the fixed cylinder being connected to the telescopic cylinder via a hydraulic cylinder.
[0008] Furthermore, the swing anti-breakage gate includes: a swing gate shaft installed at the bottom of the fixed cylinder of the telescopic chute, a grooved gate plate driven by a hydraulic cylinder or hydraulic motor to swing around the swing gate shaft, and the discharge end of the grooved gate plate is provided with the material cutting gate.
[0009] Furthermore, the grooved gate includes a base plate and side plates installed on both sides of the base plate.
[0010] Furthermore, the material cutting gate includes: a material cutting gate shaft installed at the end of the bottom plate of the grooved gate plate, and a fan-shaped swing plate driven by a hydraulic cylinder or a hydraulic motor to swing around the material cutting gate shaft, wherein the fan-shaped swing plate is fixedly connected to the arc-shaped material cutting plate.
[0011] Furthermore, the vehicle towing device includes a towing motor, which drives a pallet carrying the vehicle via a steel cable, and the bottom of the pallet is provided with multiple rollers that move with the pallet.
[0012] Furthermore, the weighing scale includes a weighing plate, on the bottom of which multiple weighing sensors are evenly distributed.
[0013] A method for environmentally friendly quantitative loading of coke using the above-mentioned equipment, comprising the following steps: Step 1, feeding: The belt conveyor transports coke into the silo for temporary storage. During the loading process, the silo should maintain a loading capacity of 1-2 cars. Step 2, vehicle enters loading position: The automatic loading door opens, the vehicle drives into the pallet at the initial end, and the front of the truck bed is directly facing the position below the chute in the initial state. The vehicle stops and is parked. The weighing sensor of the weighbridge begins to monitor the weight change on the pallet and records the weight of the empty vehicle. Step 3, Start the chute: The chute extends downward from its initial position. During the extension process, the arc-shaped gate for material discharge is opened to allow coke to enter the chute, and the dust collector is turned on at the same time. Step 4, Discharge: When the telescopic cylinder of the chute approaches the floor of the car body, open the swing anti-breakage gate and the cutting gate to allow the coke to accumulate at the front of the car body. As the height of the accumulation increases, the chute retracts, raising the material pile to a suitable height for loading. Start the vehicle towing device, and the vehicle moves forward slowly with the pallet, allowing the material pile to accumulate evenly in the car body. Step 5, terminate material discharge: When the weighing sensor of the local scale detects that the amount of coke entering the car is close to the required loading amount, reduce the opening of the material discharge arc gate. When the required loading amount is reached, close the material discharge gate, and then close the swing anti-breakage gate and the material discharge arc gate. Step 6, End of loading: The chute retracts to its initial position, and the pallet reaches its end position. The vehicle releases its parking brake and drives away from the pallet, then passes through the automatic exit door and drives out. The pallet returns to its initial position, ready for the next round of loading.
[0014] The advantages and beneficial effects of this invention are as follows: Addressing the fragile and poor flowability of coke, this invention reduces the flow path of coke during loading by eliminating the weighing hopper and employing a ground-level weighing system capable of towing vehicles. An arc-shaped gate is installed between the telescopic chute and the storage silo to control the coke's descent, and an inclined gate is installed at the outlet of the telescopic chute. A stop gate is installed at the end of the inclined plate of the inclined gate, thereby reducing the height of the coke's fall and minimizing coke breakage due to large drop heights. Simultaneously, barriers and dust collection equipment are installed around the loading area to prevent dust dispersion and protect the environment. Attached Figure Description

[0017] Example 1: This embodiment is a towed, environmentally friendly, quantitative loading equipment for coke, such as... Figure 1As shown. This embodiment includes: a steel structure frame 1, from top to bottom, the steel structure frame is provided with a belt conveyor head 2, a hopper 3, a material discharge arc gate 4, a telescopic chute 5, and a swing anti-breakage gate 6. The swing anti-breakage gate has a material cutting gate 7 at the end of its gate plate. The lower part of the steel structure frame is provided with a closed dust cover 8 with a dust removal device. The two ends of the closed dust cover are provided with an automatic vehicle entry door 801 and an automatic vehicle exit door 801. The ground inside the closed dust cover is provided with a vehicle towing device 9 and a floor scale 10 from top to bottom. The floor scale is electrically connected to a controller. The controller is electrically connected to the dust removal device, the belt conveyor, the material level indicator in the hopper, the material discharge arc gate, the telescopic chute, the swing anti-breakage gate, the material cutting gate, and the vehicle towing device. Figure 2 As shown.
[0018] To address the fragile and poor flowability of coke, this embodiment employs measures to minimize the height and number of descent stages of the coke. This primarily involves abandoning the traditional weighing hopper at the loading station, thus reducing the number of descent stages. It also lowers the height of the steel structure frame, which, as the overall support structure, must be stable and reliable to ensure safe production; therefore, it accounts for a significant portion of the total cost of the loading station. The reduced height of the steel structure frame results in a significant cost decrease.
[0019] The belt conveyor described in this embodiment transports coke piled on or near the ground to the top of a steel structure frame, where it enters a silo. The belt conveyor can use frequency conversion to regulate its conveying speed, ensuring the coke level in the silo is stable enough for loading onto trucks. A level sensor can be installed in the silo to control the conveyor speed based on the coke level, typically maintaining a load capacity sufficient for 1-2 trucks.
[0020] The silo can be cylindrical at the top and conical at the bottom, allowing the coke to fall naturally under gravity, forming an automatic material flow. An arc-shaped gate at the bottom of the silo intercepts the material. Because coke has poor flowability, very rough particle surfaces, and significant friction between particles, it not only has poor flowability but also creates considerable resistance for various moving equipment. Therefore, this embodiment uses an arc-shaped gate at the silo's outlet. When the coke flows out of the silo, it is acted upon by gravity, moving vertically downwards. The gate's movement trajectory is circular, moving diagonally upwards when opening. Figure 3 In the direction indicated by the middle arrow B, the friction between the gate and the coke is relatively small, resulting in a relatively smaller opening force compared to a flat gate.
[0021] The telescopic chute described is a straight-up-down telescopic chute. This chute has a simple structure and can be controlled by a hydraulic cylinder for vertical movement. When unloading begins, the chute extends to get as close as possible to the bottom of the car body, allowing the coke to fall into the car body with minimal distance, preventing coke particle breakage. As the coke accumulates on the car body floor, the telescopic chute rises with the increasing height of the pile, ensuring smooth coke accumulation.
[0022] At the bottom of the telescopic chute, this embodiment features a swing-type anti-breakage gate with an inclined groove. When closed, this gate seals the entire bottom of the chute, preventing coke from flowing out. When open, the gate swings downwards, forming a ramp that allows coke to flow down into the car body, thus preventing coke particle breakage. The cross-sectional shape of the swing-type anti-breakage gate can be designed as a scoop shape to store a small amount of coke. Because when the loading is about to reach its capacity, even if the discharge arc-shaped gate reduces its opening or closes completely, some coke remains in the chute. When the weighing sensor indicates that the coke in the car body has reached its loading capacity, the discharge gate immediately closes, and the remaining coke in the chute falls into the scoop-shaped gate of the swing-type anti-breakage gate, preventing spillage.
[0023] Since there is no weighing bin, other weighing methods are needed to measure the amount of goods loaded onto the truck. This embodiment uses a weighbridge to monitor the weight of the goods throughout the entire loading process, from when the truck enters empty to when it leaves fully loaded. While weighbridge monitoring is simple and reliable, accurately controlling the weight of coke entering the truck compartment is a challenging problem.
[0024] This embodiment employs a simple method: a material-cutting gate is installed at the coke outlet position of the swing-type anti-breakage gate. Once the required loading volume is reached, the material-cutting gate is immediately closed, ensuring the material in the car reaches the required weight. The material-cutting gate is installed at the end of the scoop-shaped gate plate of the swing-type anti-breakage gate. It operates together with the swing-type anti-breakage gate at the start of unloading, opening fully. It only operates again at the end of loading to cut off the material, and then lifts together with the swing-type anti-breakage gate. Figure 3 The position indicated by the dashed line.
[0025] To address the environmental impact of excessive dust generated during coke loading, this embodiment incorporates a sealed dust cover at the loading station. The dust cover features automatically opening entrance and exit doors. The automatic opening of the doors can utilize conventional automatic door opening devices without requiring connection to a controller. Alternatively, dedicated vehicle sensors can control the opening and closing of the automatic doors. A dust collection device can be installed within the sealed dust cover to collect the dust generated during coke loading, preventing harm to the surrounding environment and the health of workers.
[0026] The controller is an electronic device with storage and computing capabilities, typically an industrial control computer or PLC. It controls the loading process through control software based on the loading process method, managing the conveyor belts, chutes, drive devices, and various gates at the loading station. The electrical connection between the controller and the conveyor belt refers to the controller's connection to the conveyor belt's frequency converter to control the conveyor belt's power and adjust its conveyor capacity. The electrical connection between the controller and the chutes refers to the controller's connection to the electrical control device of the chutes' hydraulic cylinders, controlling the movement of the hydraulic cylinders via electrical signals. The electrical connection between the controller and each gate refers to the controller's connection to the electrical control device of each gate's hydraulic cylinder or hydraulic motor. Typically, the controller is connected to a host computer, which can be a computer in the coke transportation or sales department, to provide basic loading information, including vehicle information, coke loading quantity, particle size, etc.
[0027] Example 2: This embodiment is an improvement upon Embodiment 1, detailing the enclosed dust cover. The dust removal device described in this embodiment is located on top of the enclosed dust cover and includes: a suction hood 803, which is connected to a dust collector 805 via a pipe 804. Figure 1 As shown.
[0028] The dust collector is installed on top of a sealed dust cover for easy connection of pipes. Similar to a vacuum cleaner, it uses a vacuum pump to generate strong suction to absorb dust generated during loading.
[0029] Example 3: This embodiment is an improvement upon the above embodiment, a refinement of the material-cutting arc gate. The material-cutting arc gate in this embodiment includes: a gate channel 401, with an arc gate shaft 402 at the bottom of the channel. The arc gate shaft is horizontally installed, its central axis perpendicular to the vehicle's direction of travel. A swing rod 403, driven by a hydraulic cylinder or hydraulic motor, is mounted on the arc gate shaft and can swing around it. The swing rod is fixedly connected to an arc gate plate 404. Figure 3 As shown.
[0030] Opening of the swing-shaped arc gate ( Figure 3 (shown by the solid line) and closed state ( Figure 3 (As shown by the dashed line) The pressure exerted on the gate is much less than that on a flat gate, which is a significant advantage for materials with high frictional resistance, such as coke. The swing arm can be driven by a hydraulic motor or a hydraulic cylinder to rotate on the gate hinge. The swing arm has left and right sides, and its top ends connect to the two sides of the arc-shaped gate, making the gate as a whole stable and safe.
[0031] Example 4: This embodiment is an improvement upon the above embodiment, a refinement of the telescopic chute described in the above embodiment. The telescopic chute in this embodiment includes: a fixed cylinder 501 installed below the material discharge arc-shaped gate; the fixed cylinder is connected to the telescopic cylinder 503 via a hydraulic cylinder 502. Figure 3 As shown.
[0032] The telescopic chute described in this embodiment adopts a vertical lifting form, which is simple in structure and less prone to failure.
[0033] Example 5: This embodiment is an improvement upon the above embodiment, a refinement of the swing-type anti-breakage gate. The swing-type anti-breakage gate in this embodiment includes: a swing gate shaft 601 installed at the bottom of the fixed cylinder of the telescopic chute; a grooved gate plate 602, driven by a hydraulic cylinder or hydraulic motor, capable of swinging around the swing gate shaft, mounted on the swing gate shaft; and a material-cutting gate at the discharge end of the grooved gate plate. Figure 3 As shown.
[0034] The swing-type anti-breakage gate described in this embodiment is installed at the outlet of the chute to intercept a portion of the falling material. The swing-type anti-breakage gate can be designed in the shape of a scoop to store a small amount of coke. The purpose of storing a small amount of coke is that when the arc-shaped gate for intercepting material opens, the coke falls a certain distance due to the extension of the chute, and at this time the swing-type anti-breakage gate has not yet opened (it is in a state of...). Figure 3 (as indicated by the dotted line) If a small amount of coke remains on the scoop-shaped gate of the swing anti-breakage gate, the remaining coke will buffer the falling coke, thereby reducing coke breakage.
[0035] Example 6: This embodiment is an improvement upon the above embodiment, a refinement of the grooved gate. The grooved gate in this embodiment includes: a base plate 6021 and side plates 6022 installed on both sides of the base plate, as shown below. Figure 4 As shown.
[0036] The grooved gate with two side plates described in this embodiment forms a sieve shape to store a small amount of coke and buffer falling coke particles.
[0037] Example 7: This embodiment is an improvement upon the above embodiment, a refinement of the material-cutting gate in the above embodiment. The material-cutting gate in this embodiment includes: a material-cutting gate shaft 701 installed at the end of the bottom plate of the groove-shaped gate plate; a fan-shaped swing plate 702 driven by a hydraulic cylinder or hydraulic motor to swing around the material-cutting gate shaft is provided on the material-cutting gate shaft; the fan-shaped swing plate is fixedly connected to the arc-shaped material-cutting plate 703, as follows. Figure 3 As shown.
[0038] The main function of the material interception gate is to precisely stop the material flow, ensuring a certain accuracy in the loading volume. The material interception gate described in this embodiment is a swing gate, primarily to reduce the frictional resistance of the intermittent coke, and also for ease of design and installation.
[0039] Example 8: This embodiment is an improvement upon the above embodiment, detailing the vehicle towing device. The vehicle towing device in this embodiment includes: a towing motor 901, which drives a vehicle-carrying pallet 903 via a steel cable 902. The bottom of the pallet is provided with multiple rollers 904 that move with the pallet. Figure 1 As shown.
[0040] The vehicle towing device described in this embodiment adopts a simple roller method, that is, rollers are arranged in rows under a flat plate. The movement of the pallet is powered by a motor driving a winch and steel cable to pull the pallet. The vehicle only needs to be parked on the pallet, and it can move with the pallet to form the displacement during loading, so that the coke is evenly piled in the car body.
[0041] Example 9: This embodiment is an improvement upon the above embodiment, a refinement of the floor scale described in the above embodiment. The floor scale described in this embodiment includes: a weighing plate 1001, and multiple weighing sensors 1002 are evenly distributed on the bottom of the weighing plate, such as... Figure 1 As shown.
[0042] The weighing plate is a plate that occupies the entire loading area. The entire loading process, from start to finish, takes place on this plate. Therefore, weighing sensors are evenly distributed across the lower part of the plate. These weighing sensors can be arranged in a grid pattern or a staggered, uniform arrangement to ensure even measurement of the weight of the entire vehicle and the loaded coke.
[0043] Example 10: This embodiment describes a method for environmentally friendly quantitative loading of coke using the equipment described in the above embodiments. The method utilizes an electronic control system at the loading station as software to automate the loading process. The specific steps of the method are as follows, and the flow is as follows: Figure 5 As shown: Step 1, feeding: The belt conveyor transports coke into the silo for temporary storage. During the loading process, the silo should maintain a loading capacity of 1-2 cars.
[0044] Before loading, it is necessary to obtain information about the vehicle, including: the dimensions of the car body, the amount to be loaded, the particle size of the coke, etc., and to calculate the height of the coke pile in the car body so that the coke piled in the car body does not exceed the height of the car body side panels and can be evenly spread in the car body to avoid uneven loading.
[0045] Step 2, vehicle enters loading position: The automatic loading door opens, the vehicle drives into the pallet at the initial end, and the front of the vehicle is aligned with the position below the chute in the initial state. The vehicle stops and is parked. The weighing sensor of the weighbridge begins to monitor the weight change on the pallet and records the weight of the empty vehicle.
[0046] The initial position of the tray refers to the position where the tray is closest to the automatic entry door. Figure 1 The middle pallet represents the initial position, while the dotted line indicates the final position of the pallet. After the vehicle enters, it should immediately drive onto the pallet. Once the vehicle is fully inside the pallet, the front of the car body should be aligned with the outlet of the chute.
[0047] Step 3, Start the chute: The chute extends downward from its initial position. During the extension process, the arc-shaped gate for material discharge is opened to allow coke to enter the chute, and the dust collector is turned on at the same time.
[0048] The initial position of the chute refers to the telescopic chute's telescopic cylinder being fully retracted into the fixed cylinder, such as... Figure 1 As shown in the implementation, Figure 1 The dashed line in the image indicates the telescopic cylinder is fully extended.
[0049] Step 4, Discharge: When the telescopic cylinder of the chute approaches the floor of the car body, open the swing anti-breakage gate and the cutting gate to allow the coke to accumulate at the front of the car body. As the height of the accumulation increases, the chute retracts, raising the material pile to a suitable height for loading. Start the vehicle towing device, and the vehicle moves slowly forward with the pallet, allowing the material pile to accumulate evenly in the car body.
[0050] When the telescopic cylinder of the chute is extended to its maximum length, the swing anti-breakage gate and the intercepting gate open. At this time, the swing anti-breakage gate acts like an inclined slide, allowing coke to slide down into the car body and accumulate. The accumulation height of the coke in the car body is pre-calculated by the controller. Normally, because coke has a relatively low specific gravity, it must be piled up to the height of the car body's side panels.
[0051] Step 5, terminate material discharge: When the weighing sensor of the local scale detects that the amount of coke entering the car compartment is close to the required loading amount, reduce the opening of the material discharge arc gate. When the required loading amount is reached, close the material discharge gate, and then close the swing anti-breakage gate and the material discharge arc gate.
[0052] Before stopping the discharge, the outlet of the chute should have reached the rear of the car, and the outlet of the swing anti-breakage gate should be at the top of the stockpile. When the car is close to being full, the opening of the discharge arc gate should be reduced first, and then the gate should be gradually closed so that the coke in the hopper no longer enters the chute. However, there is still a small amount of coke in the chute, which can continue to be discharged into the car. Once the sensor indicates that the loading amount has reached the requirement, the discharge gate should be closed immediately so that the coke in the chute no longer falls into the car, thus precisely controlling the loading amount.
[0053] Step 6, End of loading: The chute retracts to its initial position, and the pallet reaches its end position. The vehicle releases its parking brake and drives away from the pallet, then passes through the automatic exit door and drives out. The pallet returns to its initial position, ready for the next round of loading.
[0054] Due to differences in vehicle length, the pallet may not reach the final destination after loading and unloading. When the vehicle body is short, the pallet must continue moving forward until the final destination after loading and unloading. Figure 1 (The vehicle can only leave the pallet and pass through the automatic exit door after the position of the dotted line on the pallet is reached). Because the dust generated during coke loading is very serious and will be generated during vehicle movement, the dust collector can only be turned off after the vehicle has left the automatic exit door if there is no next loading operation.
[0055] Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to preferred arrangements, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the present invention (such as the overall layout of the loading station, the metering and conveying speed of materials, the automatic control process, the sequence of steps, etc.) without departing from the spirit and scope of the technical solution of the present invention.
