Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal sample sampling and preparation, and particularly relates to a full-process unmanned coal sample processing system. BACKGROUND

[0002] In the coal handling process of a power plant, coal needs to go through automatic sampling, automatic sampling and preparation docking, automatic sample preparation, pneumatic conveying, automatic sample storage and automatic testing, and finally the coal quality is evaluated through automatic testing results. Among them, after the coal sample enters the full-automatic sample preparation system for sample preparation, about 90% of the discarded coal sample needs to be transported from the system to the designated location for collection. With the continuous improvement of fuel intelligent system, the sampling machine and the full-automatic sample preparation machine are no longer isolated from each other, and the automatic transfer of coal samples has become a basic function of the sampling interface.

[0003] However, in the current coal sampling and preparation system, the sample transportation in the sampling and preparation room has not been fully automated and often requires manual intervention. Manual handling and trolley transfer operations have the risk of human sample replacement, and may cause sample spillage due to sample bucket falling, with poor safety. Although some power plants have adopted automatic transfer equipment such as cableway, intelligent transfer trolley, track trolley, and unmanned aerial vehicle, there are still some deficiencies. Cableway transfer realizes full automation in the transportation process and avoids the risk of manual sample replacement, but it is easily affected by extreme weather and has high construction cost; intelligent transfer trolley has both manned and unmanned driving modes, the manned trolley needs to be operated by a professional driver, and the docking is not fully automated, and the safety of the unmanned trolley transfer system cannot be fully guaranteed; track trolley transportation realizes automation and does not require manual operation, but it has high initial investment cost, requires a large space, and has high track maintenance standards, which is not suitable for power plants with small space, special terrain, or complex layout.

[0004] In addition, in the coal sampling and preparation system, the discarded material generated by the automatic sample preparation equipment is usually piled up near the equipment and needs to be cleaned regularly by manual labor, resulting in high labor intensity, long operation time, and serious pollution to the equipment site environment. The existing discarded material collection means is mostly manual collection or vehicle transportation, which still requires manual intervention and cannot realize the automation and unmanned operation of the whole process of coal sample sampling, sample preparation, and sample discarding. Therefore, there is an urgent need for a full-process unmanned coal sample processing system that can solve the problems of human sample replacement risk in the sampling and preparation docking, manual discarded material collection, and environmental pollution in the prior art. UTILITY MODEL CONTENT

[0005] The utility model intends to provide a full-process unmanned coal sample processing system to improve the problems of human sample replacement risk in the sampling and preparation docking and manual discarded material collection in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a full-process unmanned coal sample processing system, comprising:

[0007] A belt sampler is used to collect samples from coal mines.

[0008] An automated ore sorting and packaging module is connected to the outlet end of the belt sampler and is used to process samples in batches.

[0009] The automated feeding module is connected to the outlet section of the automated ore sorting and packaging module, and is used to combine and group the samples after they have been sorted.

[0010] The robot sample preparation module is connected to the outlet of the automated feeding module and is used to prepare samples for batching and approval.

[0011] The waste material module is located between the robot sample preparation module and the mine, and is used to transport the waste material discharged by the robot sample preparation module to the mine.

[0012] Preferably, as an improvement, there are two robotic sample preparation modules, each equipped with a waste disposal module. The two robotic sample preparation modules are connected to the automated feeding module through the same roller conveyor line. It also includes a control module for monitoring the operating status of the two robotic sample preparation modules, thereby switching the conveying direction of the roller conveyor line to send the sample to the idle robotic sample preparation module.

[0013] Preferably, as an improvement, the automated ore sorting and packaging module and the automated feeding module are also connected by a roller conveyor line to realize sample transportation.

[0014] Preferably, as an improvement, the waste disposal module includes a waste disposal conveyor belt, a waste disposal chain bucket elevator, and a steel frame platform.

[0015] Preferably, as an improvement, the waste conveyor belt is equipped with baffles to prevent waste from falling.

[0016] This invention achieves fully automated coal sample processing through the coordinated operation of various modules and devices. First, after the belt sampler collects samples from the coal mine, the samples are processed in batches by the automated sorting and packaging module. They are then transported via roller conveyor to the automated feeding module for batching and grouping. The batched samples are then sent to the robotic sample preparation module for further processing by the roller conveyor. The system is equipped with two robotic sample preparation modules, and the control module monitors their operation in real time. By switching the direction of the roller conveyor, samples are automatically allocated to idle equipment to ensure efficient operation. Waste generated during sample preparation is directly transported to the mine by the waste module (including a waste conveyor belt, chain bucket elevator, and steel frame platform; the belt is equipped with baffles to prevent falling) to avoid human intervention. All stages are connected by roller conveyor lines, forming a closed-loop automated process, achieving separation of personnel and unmanned operation throughout the entire coal sample collection, preparation, and disposal process.

[0017] The advantages of this utility model include:

[0018] 1. Fully automated operation: Through the collaboration of belt sampling machines, automated ore sorting and packaging, robotic sample preparation and waste disposal modules, the entire process of sampling, sorting, combining, preparation and disposal is carried out without human intervention.

[0019] 2. Eliminate the risk of human sample replacement: The roller conveyor line runs through all modules, and the samples flow automatically in the closed system without the need for manual handling or docking, thus avoiding problems such as human sample replacement and sample spillage from the process.

[0020] 3. High-efficiency intelligent scheduling: The control module dynamically monitors the operating status of the dual-robot sample preparation module, automatically switches the conveying direction to allocate samples, and improves equipment utilization and sample preparation efficiency.

[0021] 4. Automated waste disposal: The waste module directly transports the sample preparation waste to the mine through belt conveyors, chain bucket elevators and other devices, cleaning it up in real time without accumulation, reducing manual labor intensity and avoiding waste pollution of the equipment site environment.

[0022] 5. Strong structural adaptability: Compared with traditional equipment such as cableways and track trolleys, the system relies on roller conveyor lines and modular design, making it more suitable for power plants with limited space and complex terrain, and with lower construction and maintenance costs.

[0023] 6. Safe and reliable: The waste material conveyor belt is equipped with baffles to prevent waste material from falling, and the conveying process is closed and controllable, which improves the safety of system operation; unmanned operation reduces human contact and lowers the risk of safety accidents.

[0024] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0025] The following detailed description illustrates the specific implementation method:

[0026] The reference numerals in the accompanying drawings include: 1. Belt sampler; 2. Automated ore sorting and packaging module; 3. Roller conveyor line one; 4. Automated feeding module; 5. Robot sample preparation module one; 6. Robot sample preparation module two; 7. Waste chain bucket elevator; 8. Waste conveyor belt; 9. Steel frame platform; 10.

[0027] The basic implementation examples are as follows: Figure 1 As shown: A fully automated coal sample processing system, comprising:

[0028] Belt sampler 1 is used to sample coal from coal mines to obtain samples.

[0029] The automated ore sorting and packaging module 2 is connected to the outlet end of the belt sampler 1 and is used to process samples in batches.

[0030] An automatic loading module 4 is connected with the outlet section of the automatic ore separation and packaging module 2 through a roller conveying line 3, and is used for combining and batching the samples after separation.

[0031] A robot sample preparation module is connected with the outlet of the automatic loading module 4, and is used for sample preparation of the combined and batched samples; the robot sample preparation module includes a robot sample preparation module 1 6 and a robot sample preparation module 2 7, and each of the two robot sample preparation modules is equipped with a waste material module, and the two robot sample preparation modules are connected with the automatic loading module 4 through a same roller conveying line 5.

[0032] A control module is used for monitoring the running states of the two robot sample preparation modules, so as to switch the conveying direction of the roller conveying line to send the samples to the idle robot sample preparation module.

[0033] A waste material module is arranged between the robot sample preparation module and the mine field, and is used for conveying the waste material discharged from the robot sample preparation module to the mine field; the waste material module includes a waste material belt 9, a waste material chain bucket 8 and a steel platform 10, and the waste material belt 9 is provided with a baffle for blocking the waste material from falling.

[0034] The specific implementation process is as follows: a belt sampler 1 samples the coal mine to obtain a sample 1, and sends the sample 1 to an automatic ore separation and packaging module 2; the sampling process includes sampling, crushing and sub-sampling of the coal mine in sequence. The automatic ore separation and packaging module 2 performs batch processing on the sample 1 to obtain a sample 2; the batch processing is that the original coal sample collected by the belt sampler 1 is automatically divided into multiple independent sub-sample units according to preset rules (such as mine source, time, sampling batch, sample weight / volume, etc.), and is packaged (such as being loaded into a standard sample barrel and being labeled, etc.). The coal sample collected by the belt sampler 1 can be continuous or large in volume, and needs to be split into small batches of samples that meet the requirements of subsequent processing (for example, being packed according to different mine points, transportation batches or single processing capacity of sample preparation equipment) through screening, sub-sampling and weighing devices of the ore separation and packaging module. Each sub-sample unit is attached with an independent identification (such as a bar code or an RFID tag) to record sample source, time and other information, so as to facilitate whole-process tracing. In this way, the samples of different mine sources and times are prevented from being mixed, and the sample uniqueness and traceability of subsequent sample preparation and testing are ensured. Through automatic separation and packaging, the sampling end and the subsequent process are connected without manual intervention, and the risk of manual sample replacement and sample error is eliminated.

[0035] The sample two is then sent to the automatic loading module 4 through the roller conveying line 3, and the automatic loading module 4 performs sample combining and batch processing on the sample two to obtain a sample three. The sample combining and batch processing means that multiple sub-sample units (which can come from the same mine source, the same batch, or samples that need to be combined) after batch processing are automatically collected and combined into a complete target batch sample according to rules for unified processing by the robot sample preparation module. The automatic loading module 4 receives multiple sub-sample units from the sub-sample packaging module through the roller conveying line, identifies and groups them based on sample identification (such as mine source number, batch number). The sub-samples belonging to the same target batch (for example, multiple sub-samples of the same coal mine or the same transportation batch) are gathered into the same conveying path and combined into a complete batch to be prepared, which can include operations such as unpacking, mixing, and reweighing. In this way, multiple sub-samples of the same batch can be mixed to ensure that the sample before sample preparation is representative, and sample deviation caused by sub-packaging is avoided. The robot sample preparation module usually needs to process a certain amount of sample (such as 5 kg for a single sample preparation), and sample combining and batching can combine scattered sub-samples (such as 2 kg each) into a batch that meets the processing capacity of the equipment (such as 6 kg by combining three 2 kg sub-samples), reducing equipment idle and repeated operations. Through automatic batch combining, the whole process of data penetration (such as batch information following the sample) from “sampling → sub-packaging → batch combining → sample preparation” is realized, providing a data basis for subsequent scrap processing and test result association.

[0036] The sample three is transferred to the robot sample preparation module through the roller conveying line for sample preparation processing, which includes the following processing of the coal sample:

[0037] Drying and crushing: The particle size of the dried coal sample is reduced to a specified range (such as ≤13 mm, ≤3 mm, etc.) through a crusher to facilitate subsequent sub-division and testing.

[0038] Screening: Use screening equipment to remove oversized particles to ensure uniform sample particle size (such as using a vibrating screen to separate unqualified particles).

[0039] Sub-division: The coal sample is reduced to the required amount for testing (such as from 5 kg to 100 g) by a sub-division machine (such as a two-division machine or a rotary sub-division machine) while ensuring the representativeness of the sample (i.e., the composition of the sample after sub-division is consistent with that of the original sample).

[0040] Mixing: The sub-divided sample is uniformly mixed to avoid segregation of components (such as through a drum-type mixing machine).

[0041] Packaging: The prepared sample is packed into a standard sample bottle / bag, and a unique identifier (such as a two-dimensional code or an RFID tag) is attached for subsequent automatic testing.

[0042] The sample is grabbed, transferred, equipment start-stop and other operations in the process are realized by the mechanical arm, replacing manual intervention (such as automatic feeding to the crusher, automatic cleaning of the residual sample of the equipment).

[0043] When the robot sample preparation module 1 6 is idle, the control module controls the sample barrel of the roller conveyor line 2 5 to be transported to the robot sample preparation module 1 6, and when the robot sample preparation module 2 7 is idle, the control module controls the sample barrel of the roller conveyor line 2 5 to be transported to the robot sample preparation module 2 7. The waste produced after the sample preparation process is transported to the waste belt 9 supported by the steel frame platform 1 0 by the waste chain bucket 8, and the waste belt 9 transports the waste to the mine site. The baffle on the waste belt 9 blocks the coal from falling during the transportation of the waste.

[0044] Thus, the belt sampler 1, the roller conveyor line, the robot sample preparation module, the waste module and other devices are organically matched to realize the whole-process unmanned operation, and manual interference and environmental pollution are avoided.

[0045] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
