Technical Field

[0001] The present application relates to the field of coal quality detection technology, and in particular to a coal quality sampling system. Background Art

[0002] As a traditional energy generation method, the power generation efficiency and environmental emission standards of thermal power plants depend largely on the quality of the coal burned. High-quality coal can not only improve power generation efficiency and reduce coal consumption, but also reduce the emission of harmful gases, playing a positive role in environmental protection. Therefore, ensuring coal quality has become an important link in the operation of thermal power plants.

[0003] In order to ensure that the coal quality meets the requirements of the power plant, it is usually necessary to conduct quality inspection on the incoming coal. However, in the existing technology, the incoming coal quality inspection mostly relies on manual sampling, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate test results.

[0013] Compared with the prior art, this application has at least the following beneficial effects:

[0014] In the coal quality sampling system, when the transport vehicle carrying coal enters the sampling area, the spiral sampling head moves to the top of the transport vehicle under the drive of the driving member, and the spiral sampling head starts to drill the coal sample.

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as an emphasis on importance or order, etc.). Expressions such as "include", "comprise", "have", etc. also mean "not limited to" (certain units, components, materials, steps, etc.); the arrow shown in the figure is the direction of coal sample transportation.

[0022] refer to Figure 1-2 The present application discloses a coal quality sampling system, including a main frame (not shown in the figure), a spiral sampling head 2 connected to the main frame and used for drilling coal samples in a transport vehicle 1, a driving member 3 connected to the main frame and used to drive the spiral sampling head 2 to move, a crusher 5 connected to the main frame and used to crush the coal sample taken by the spiral sampling head 2, a primary feeder 4 connected to the main frame and used to transport the coal sample taken by the spiral sampling head 2 to the crusher 5, a reducer 6 connected to the main frame and used to screen the coal sample after being crushed by the crusher 5, and a packaging machine 8 connected to the main frame and used to package the coal sample after being screened by the reducer 6.

[0023] In the present coal quality sampling system, after the transport vehicle 1 carrying coal enters the sampling area, the spiral sampling head 2 is driven by the driving member 3 to move to the top of the transport vehicle 1, and the spiral sampling head 2 starts to drill the coal sample, and the drilled coal sample is then sent to the crusher 5 by the primary feeder 4 for crushing to reduce the particle size of the coal sample for subsequent processing. The crushed coal sample is screened by the reducer 6 to select the coal sample with a particle size range that meets the experimental requirements, and then packaged by the packaging machine 8. The coal samples are packaged in the packaging barrel of the packaging machine 8 in turn, and each packaging barrel contains a certain number of coal samples, which is convenient for the experimenter to take on demand; compared with traditional manual sampling, the coal quality sampling system of the present application realizes the automation of the entire sampling process, thereby improving the sampling efficiency, reducing human errors, and reducing labor intensity.

[0024] Among them, the spiral sampling head 2 (spiral sampling head), crusher 5, reducer 6 (electric reducer) and packaging machine 8 are all existing technologies, and this application will not go into details about them; among them, the packaging machine 8 is widely used in various industries, such as in the field of food processing, and can also be called a packaging machine, filling machine or filling and sealing machine.

[0025] In some embodiments, the reducer 6 can transfer the remaining coal samples from the screening to other locations for unified processing.

[0026] The main frame may be a steel frame structure.

[0027] The driving member 3 is a crane connected to the main frame, and is used to drive the spiral sampling head 2 to move along a horizontal plane. The spiral sampling head 2 is located above the driving path of the transport vehicle 1 .

[0028] In this coal quality sampling system, when the transport vehicle 1 carrying coal enters the sampling area, the overhead crane drives the spiral sampling head 2 to move to the top of the transport vehicle 1, and then the spiral sampling head 2 begins to extend downward into the coal pile in the transport vehicle 1 to drill and sample. Generally, multiple samplings are performed at different positions of the coal transported by the transport vehicle 1.

[0029] In some embodiments, the driving member 3 may also be other mechanical devices that can drive the spiral sampling head 2 to move in a horizontal plane.

[0030] The primary feeder 4 includes a first conveying part 41 connected to the main frame and used to receive the coal sample taken by the spiral sampling head 2, and a second conveying part 42 connected to the end of the first conveying part 41 away from the spiral sampling head 2. The first conveying part 41 is arranged in an inclined direction, and the second conveying part 42 is connected to the main frame and arranged in a horizontal direction. The first conveying part 41 and the second conveying part 42 have a coal conveying channel 43. The second conveying part 42 is arranged with a conveyor belt 44 in the coal conveying channel 43. The crusher 5 is located at the bottom of the discharge port of the second conveying part 42.

[0031] The coal sample taken by the spiral sampling head 2 is first fed into the first conveying part 41 of the primary feeder 4, which is arranged in an inclined direction and uses gravity to assist the coal sample to be transported downward. Subsequently, the coal sample enters the second conveying part 42, which is arranged in a horizontal direction and is equipped with a conveyor belt 44 to smoothly convey the coal sample to the crusher 5. The crusher 5 is located at the bottom of the discharge port of the second conveying part 42, and can receive and crush the coal sample to ensure continuous processing of the coal sample.

[0032] The second conveying part 42 is provided with a combing plate 45 in the coal conveying channel 43 , and a combing gap 451 for arranging the coal flow is formed between the combing plate 45 and the conveyor belt 44 .

[0033] When the coal sample enters the second conveying part 42 from the first conveying part 41, the combing gap 451 formed between the combing plate 45 and the conveyor belt 44 can effectively sort out the coal flow, making the coal sample more evenly distributed. This process not only reduces the accumulation and blockage of the coal sample during the transmission process, but also improves the stability and continuity of the coal sample transportation. The sorted coal flow enters the crusher 5 more smoothly for crushing, ensuring the crushing efficiency and crushing quality.

[0034] The second conveying portion 42 is provided with a magnetic attraction member 46 in the coal conveying passage 43 for absorbing iron in the coal flow. The magnetic attraction member 46 is located on a side of the combing plate 45 away from the first conveying portion 41 .

[0035] In the present coal quality sampling system, the magnetic element 46 in the second conveying part 42 plays a key role. The magnetic element 46 is located on the side of the combing plate 45 away from the first conveying part 41. When the coal sample passes through this area, the magnetic element 46 can effectively absorb the iron impurities in the coal flow, including the iron impurities in the coal sample itself, and the iron parts that fall off from other components during transportation or transmission. This process not only ensures the purity of the coal sample, but also avoids the damage caused by the iron impurities to the subsequent crusher 5 and other equipment, thereby improving the service life and operation efficiency of the equipment.

[0036] In some other embodiments, the magnetic attraction member 46 is an electromagnet detachably connected to the second conveying portion 42. This makes the magnetic attraction member 46 more flexible and convenient during use. The magnetic force of the electromagnet can be adjusted as needed to meet the adsorption requirements of iron impurities in different coal samples. When the electromagnet is energized, a strong magnetic field is generated, which can effectively adsorb iron impurities in the passing coal flow. After use, the magnetic field can be eliminated by cutting off the power supply, which is convenient for cleaning and maintenance of the magnetic attraction member 46.

[0037] A transfer belt conveyor 7 is connected between the reducer 6 and the packaging machine 8. The transfer belt conveyor 7 ensures the stability and continuity of the coal sample through continuous belt transportation, avoids the scattering and loss of the coal sample during the transmission process, and smoothly transports the coal sample screened by the reducer 6 to the packaging machine 8. Among them, the transfer belt conveyor 7 is a prior art and will not be described in detail in this application.

[0038] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0039] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
