Description

Technical Field

[0001] The present invention relates to the technical field of material acceptance, and in particular to a material acceptance system for coal, coke and the like and a control method thereof. Background Art

[0002] The prior art CN202320031975.5 "A new type of secondary feeder discarding device for coal sampling machine entering the furnace" discloses a discarding bucket elevator and a primary sampler and primary feeder on the lower side. The lower end of the primary feeder is fixedly connected to a crusher, and the lower end of the crusher is fixedly connected to a secondary feeder reducer. The lower side of the secondary feeder reducer is provided with a sample collector. By improving the traditional chain-type scraper discarding device into the existing spiral discarding machine, by installing a motor, a rotating rod and a spiral blade, when the material is conveyed through the feed port for discard screening, the motor drives the rotating rod to drive the spiral blade to rotate, and the material is conveyed in a spiral manner, so that there will be no accumulation between the materials, and the materials with higher humidity can be dispersed and conveyed during transportation, eliminating the jamming defects of the traditional chain-type discarding device and improving the speed and efficiency of discarding.

[0003] The coal, coke, and other material acceptance systems are intelligent management and control systems designed for the inspection and acceptance of incoming coal or coke by truck. They primarily consist of a vehicle control and guidance module, an automatic sampling module, a first-level sampling belt conveyor, an online particle size analysis module, an online fuel testing module, a sample preparation and collection module, a raw material collection module, and a residual material collection module. Traditional acceptance systems only involve sampling, preparation, and collection. Samples must be taken to a sample preparation room for testing and analysis, and the results are typically not available until the next day, resulting in poor timeliness. By the time the test results are available, the materials have already been stored or stored. Summary of the Invention

[0004] The present invention primarily addresses the shortcomings of the prior art by providing a material acceptance system and control method for coal, coke, and other materials. This system, with its compact structure, convenient operation, and stable operation, addresses the issue of online inspection and acceptance of materials such as coal and coke. Integrating the existing automatic sampling function with a new online inspection module, it displays material characteristic data in real time. Based on the online inspection results, it quickly determines whether the inspection meets the requirements or guides the scientific stacking of materials.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: A system for accepting and inspecting materials such as coal and coke comprises a sampling steel structure scaffolding, wherein a carriage spiral sampler is arranged in the sampling steel structure scaffolding, a sampling head elevator for driving the carriage spiral sampler to move up and down is arranged between the carriage spiral sampler and the sampling steel structure scaffolding, a walking trolley for driving the longitudinal displacement of the carriage spiral sampler is arranged between the sampling head elevator and the sampling steel structure scaffolding, a walking trolley for driving the lateral displacement of the carriage spiral sampler is arranged between the walking trolley and the sampling head elevator, a platform railing steel structure is arranged on the side of the sampling steel structure scaffolding, a surplus coal bin is arranged on the platform railing steel structure, a first-level bidirectional scraping and sweeping sampler is arranged between the carriage spiral sampler and the surplus coal bin, a temporary material storage pipe is arranged between the first-level bidirectional scraping and sweeping sampler and the carriage spiral sampler, and a first-level reduction sampling belt conveyor is arranged between the first-level bidirectional scraping and sweeping sampler and the surplus coal bin.

[0006] When the material is fed into the first-level reduction sampling belt conveyor, the acceptance system selects the first-level bidirectional scraping sampler arranged on it according to the type and characteristics of the material to take samples and distribute the samples.

[0007] Preferably, a first-level crusher is provided between the first-level reduction sampling belt conveyor and the remaining coal bin, a second-level reduction belt feeder is provided between the first-level crusher and the remaining coal bin, and a bucket elevator is provided between the second-level reduction belt feeder and the remaining coal bin.

[0008] Preferably, the secondary reduction belt feeder is provided with a secondary bidirectional scraping and sweeping sampler, the lower end of the secondary bidirectional scraping and sweeping sampler is provided with a sample collector, and an online detection instrument for detecting the material at the upper end of the secondary reduction belt feeder is provided between the secondary bidirectional scraping and sweeping sampler and the primary crusher.

[0009] Online testing instruments display the material's calorific value, moisture, ash, sulfur content, and other information in real time. If any data is abnormal, the acceptance system will respond accordingly, including rejection, manual inspection, and separate stacking. The system can also provide the vehicle management system with a corresponding stacking route based on the material's calorific value and sulfur content.

[0010] The material is sent to the first-level crusher via the first-level reduction belt conveyor, where the sample is crushed. After reaching the corresponding particle size, it is reduced by the reducer and then sent to the sample collector. The sample collector will use the results of laboratory tests on the material for commercial settlement.

[0011] Preferably, both ends of the first-level bidirectional scraping sampler are provided with drum screens, the lower end of the drum screen is provided with a first-level return belt conveyor, a second-level return belt conveyor is provided between the first-level return belt conveyor and the bucket elevator, and a monitor is provided on the second-level return belt conveyor.

[0012] Preferably, a sampling locator is provided at one end of the traveling trolley, a vehicle positioning detection sensor is provided at the lower part of the sampling steel structure scaffolding, and a gate radar system and a vehicle identification system are provided at the front and rear ends of the sampling steel structure scaffolding.

[0013] After registering, vehicles are guided to the corresponding sampling and acceptance facility entrance via signage based on the material information read by the system. Vehicle information is read through license plate recognition to determine if the vehicle is transporting materials. If the vehicle is guided into the sampling area, it will be allowed into the vehicle area for the first time. The vehicle's length, width, and height are measured and recorded by the vehicle scanning mechanism, and archived for subsequent automatic sampling. Once the vehicle enters the sampling area, the vehicle positioning system determines whether it has stopped in place. Once stopped, the sampling system retrieves the relevant material acceptance procedures based on the material information read.

[0014] Preferably, an electric control cabinet is provided under the first-level return belt conveyor, which is electrically connected to the sampling locator, sampling head elevator, carriage spiral sampler, walking trolley, walking cart, first-level bidirectional scraping and sweeping sampler, first-level reduction sampling belt conveyor, first-level crusher, bucket elevator, second-level bidirectional scraping and sweeping sampler, online detection instrument, sample collector, second-level reduction belt feeder, monitor, first-level return belt conveyor, second-level return belt conveyor, vehicle positioning detection sensor, gate radar system and vehicle identification system through the electric control cabinet.

[0015] Preferably, a raw material sample collector is provided between the first-stage bidirectional scraping sampler and the first-stage crusher.

[0016] When the material cannot be damaged or is too wet to be handled, the raw material sampler on the first-stage belt conveyor takes samples directly and sends them to the collector. The collector is a multi-station collector and the corresponding collector can be selected according to the type of material. The collected samples are manually processed and tested.

[0017] A control method for a material acceptance system for coal, coke, etc., comprising the following steps: Step 1: The incoming vehicle collects information and guides its positioning through the sampling locator, vehicle positioning detection sensor, gate radar system and vehicle identification system.

[0018] Step 2: After the incoming vehicle enters the sampling area of ​​the sampling steel structure scaffolding, the walking trolley and walking cart drive the carriage spiral sampler to the top of the incoming vehicle, and then the sampling head elevator drives the carriage spiral sampler to sample the materials on the incoming vehicle.

[0019] Step 3: Store the sampled materials into a temporary storage tube. After the sampling is completed, the first-level bidirectional scraping sampler runs to the unloading point, and the unloading mechanism unloads the coal sample into the first-level reduction sampling belt conveyor.

[0020] Step 4: The first-stage reduction sampling belt conveyor transports the material to the first-stage crusher, and then forms a uniform material flow after passing through the second-stage reduction belt feeder, which is displayed online in real time by the online detection instrument.

[0021] Step 5: The materials after online inspection are transported to the residual coal bunker through bucket elevator.

[0022] Preferably, when the acceptance system determines that the material needs to be analyzed for particle size, the raw material sampler corresponding to the first-level reduction sampling belt conveyor sends the material sample into the circular drum. The circular drum rotates under the action of the motor, and the material moves in the drum along with the rotation direction of the drum. Because the screen holes installed in the drum have different sizes, materials of different particle sizes are gradually screened and separated as the drum rotates. Finally, the finished material is discharged from the grading material port below the drum. The receiving tray of each grading material port is equipped with an electronic scale, which can automatically calculate the weight of coke of each particle size by weighing. The data is sent to the computer in the control room, and the supporting software performs statistical analysis and automatically calculates the results according to the material ratio of each level. The acceptance system determines whether the material meets the requirements based on the results, and the vehicle management system guides the vehicle to the designated location for corresponding processing.

[0023] The present invention can achieve the following effects: The present invention provides a material acceptance system for coal, coke, and the like, and a control method thereof. Compared with the prior art, the system has the advantages of compact structure, convenient operation, and good operational stability, and solves the problem of online inspection and acceptance of materials such as coal and coke. In combination with the original function of automatic sampling, an online inspection module is newly added to display the characteristic data of the material in real time, and the acceptance result is quickly determined based on the online inspection result to determine whether it meets the requirements or to guide the scientific stacking of the material according to the inspection result. A matching weighing drum screen is added to directly determine the particle size ratio online for the acceptance of materials such as coke. The acceptance result is quickly judged. At the same time, the original sample module and the sample preparation module are retained to meet the acceptance requirements of different materials. BRIEF DESCRIPTION OF THE DRAWINGS
