Description

Technical Field

[0001] This utility model relates to the field of coal quality inspection and drying technology, and in particular to a sample drying device for coal quality inspection. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal plays an important role in modern industry, whether it is heavy or light industry, energy industry, metallurgy industry, chemical industry, machinery industry, or light textile industry, food industry, and transportation industry. Various industrial sectors consume a certain amount of coal to some extent. In the process of coal research, it is necessary to take coal samples from different locations, dry the coal samples after sampling, and then study the composition and other related properties of the coal. The above-mentioned drying of coal samples requires the use of drying equipment.

[0003] For example, Chinese utility model patent with announcement number "CN219674702U" discloses a sample drying device for coal testing, relating to the field of coal testing technology. It includes a drying chamber with placement frames installed at the top and bottom of the chamber's interior. Connecting components are provided between the two sets of placement frames and the drying chamber. A lead screw is connected to the top of each set of placement frames via bearings. A servo motor for driving the lead screw rotation is installed on the right side of each set of placement frames. Nuts are threaded onto the outer walls of both sets of lead screws. This utility model, through the coordinated arrangement of a mounting plate, nut, lead screw, lever, servo motor, and limiting component, allows the servo motor to start and drive the lead screw to rotate. Under the limiting action of the limiting component, the rotation of the lead screw drives the nut to move left and right. The movement of the nut causes the mounting plate to move back and forth, thereby enabling the manipulation of the coal sample.

[0004] However, the aforementioned device can easily cause the coal sample to crack and wear when it is being roughly moved during the drying process, which reduces the quality of the coal sample to some extent. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sample drying device for coal quality inspection.

[0006] This utility model provides a sample drying device for coal quality inspection, including a base and a drying chamber mounted on the base. The base is equipped with a heating component, and the interior space of the base and the drying chamber are connected by a ventilation component. The drying chamber is equipped with a shaking mechanism for accommodating and shaking the coal sample. The shaking mechanism is rotatable relative to the drying chamber, and an exhaust component is provided at the upper end of the drying chamber.

[0007] In one of the alternative technical solutions, the shaking mechanism includes a drying tube movably connected inside the drying chamber and a motor connected to the drying tube, wherein the interior of the drying tube is hollowed out to form a holding space for holding the coal sample.

[0008] In one of the alternative technical solutions, the shaking mechanism further includes a rotating shaft that runs horizontally through the drying chamber and is connected to the motor, and a mounting sleeve fitted on the rotating shaft. The outer periphery of the mounting sleeve is provided with a connecting sleeve for connecting the drying tubes, and a plurality of the drying tubes are evenly connected to the outer periphery of the mounting sleeve.

[0009] In one of the alternative technical solutions, one end of the drying tube is detachably connected to the connecting sleeve, and the other end of the drying tube is provided with a detachable end cap, which is provided with a knob.

[0010] In one of the alternative technical solutions, the interior of the drying tube is provided with a first slide rod and a second slide rod that can slide relative to the drying tube. The first slide rod has a first tray at the end near the second slide rod, and the second slide rod has a second tray at the end near the first slide rod. A holding space for holding a coal sample is formed between the first tray and the second tray.

[0011] In one of the alternative technical solutions, a first spring is provided between the first slide rod and the mounting sleeve, and a second spring is provided between the second slide rod and the end cap.

[0012] In one of the alternative technical solutions, the heating assembly includes a plurality of heating tubes, and the ventilation assembly includes a fan, an air supply pipe and a distribution pipe connected in sequence from the base toward the drying chamber.

[0013] In one of the alternative technical solutions, the ventilation assembly includes multiple air supply pipes and multiple distribution pipes, the drying chamber is provided with several partitions, the partitions divide the internal space of the drying chamber into several drying spaces, each drying space is provided with a drying mechanism, and each drying space is connected to at least one of the distribution pipes.

[0014] In one alternative technical solution, the upper surface of the drying chamber is covered by a lid, and the exhaust assembly is mounted on the lid. The exhaust assembly includes an exhaust fan embedded in the lid and a filter screen disposed below the exhaust fan.

[0015] In one of the alternative technical solutions, a dust collection drawer is provided inside the drying chamber below the drying mechanism and is slidably inserted into the drying chamber.

[0016] The above technical solution has the following beneficial effects: The sample drying device for coal quality inspection provided by this utility model can smoothly shake the coal sample by setting a shaking mechanism that can rotate relative to the drying chamber, so as to avoid the coal sample from breaking and abrading after the drying process. By setting heating components, ventilation components and exhaust components, an air duct is formed inside the drying chamber to efficiently dry the coal sample. Combined with the shaking mechanism, the coal sample is heated and dried evenly, so as to significantly improve the drying efficiency of the coal sample. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] In this utility model, unless otherwise explicitly specified and limited, the term "fixed" and similar terms should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1-4 As shown, an embodiment of the present invention provides a sample drying device for coal quality inspection, including a base 1 and a drying chamber 11 disposed on the base 1. A heating component is disposed in the base 1. The internal space of the base 1 and the drying chamber 11 are connected through a ventilation component. The drying chamber 11 is provided with a shaking mechanism for accommodating and shaking the coal sample. The shaking mechanism can rotate relative to the drying chamber 11. An exhaust component is disposed at the upper end of the drying chamber 11.

[0022] The drying box 11 and the base 1 are both hollow rectangular structures. The drying box 11 is placed on the base 1, and the interior of the drying box 11 and the base 1 are not directly connected. In order to facilitate lifting and moving, a handle 16 can be provided on the upper surface of the drying box 11. The handle 16 can be arched or ring-shaped to facilitate the user's carrying.

[0023] The base 1 is electrically connected to an external power source to drive the heating component, ventilation component, and shaking component. The heating component in the drying chamber 11 includes multiple vertically placed heating tubes 22. The ventilation component is located on the side between the base 1 and the drying chamber 11, and connects the interior of the base 1 and the drying chamber 11 to allow air to circulate between them. The heat generated by the heating tubes 22 enters the drying chamber 11 through the ventilation component and is discharged to the outside through the exhaust component at the top. When drying and inspecting coal samples, the user needs to first add the coal sample to the shaking mechanism. When the shaking mechanism rotates relative to the drying chamber 11, it drives the coal sample to rotate smoothly inside the drying chamber 11 and dries it quickly by heating the air. This achieves high-quality and rapid drying while avoiding breakage and wear of the coal sample, making the quality inspection results of the coal sample more accurate.

[0024] By setting up a shaking mechanism, the coal sample is ensured to dry evenly and is not easily broken. Combined with the heating component, ventilation component, drying chamber 11 and exhaust component connected in sequence, a drying air duct is formed, which significantly improves the drying efficiency of the coal sample.

[0025] In summary, the sample drying device for coal quality inspection disclosed in this utility model embodiment uses a swaying mechanism that can rotate relative to the drying chamber 11 to smoothly sway the coal sample, preventing the coal sample from breaking and abrading after the drying process. Furthermore, by setting up heating components, ventilation components, and exhaust components, an air duct for efficient drying of the coal sample is formed inside the drying chamber 11. Combined with the swaying mechanism, the coal sample is heated and dried evenly, significantly improving the drying efficiency of the coal sample.

[0026] In one embodiment, as shown in Figures 1 and 2, the shaking mechanism includes a drying tube 3 movably connected inside the drying chamber 11 and a motor 23 connected to the drying tube 3. The interior of the drying tube 3 is hollowed out to form a holding space for holding the coal sample.

[0027] In one embodiment, as shown in the figure, the shaking mechanism further includes a rotating shaft 18 that runs horizontally through the drying chamber 11 and is connected to the motor 23, and a mounting sleeve 31 sleeved on the rotating shaft 18. The outer periphery of the mounting sleeve 31 is provided with a connecting sleeve 32 for connecting the drying tubes 3, and a plurality of drying tubes 3 are evenly connected to the outer periphery of the mounting sleeve 31.

[0028] In one embodiment, as shown in the figure, one end of the drying tube 3 is detachably connected to the connecting sleeve 32, and the other end of the drying tube 3 is provided with a detachable end cap 36, on which a knob 4 is provided. Further, as shown in the figure, the interior of the drying tube 3 is provided with a first slide rod 34 and a second slide rod 37 that can slide relative to the drying tube 3. A first tray 35 is provided on the end of the first slide rod 34 near the end of the second slide rod 37, and a second tray 38 is provided on the end of the second slide rod 37 near the end of the first slide rod 34. A receiving space for accommodating a coal sample is formed between the first tray 35 and the second tray 38. In addition, a first spring 33 is provided between the first slide rod 34 and the mounting sleeve 31, and a second spring 39 is provided between the second slide rod 37 and the end cap 36.

[0029] In this embodiment, an end cap 36 is threaded onto the end of the drying tube 3 away from the connecting sleeve 32. A through hole is opened through the middle surface of the drying tube 3. A first slide rod 34 is slidably connected to the surface of the connecting sleeve 32. A first spring 33 is fixedly installed at the end of the first slide rod 34 near the connecting sleeve 32. The end of the first spring 33 away from the first slide rod 34 is fixedly installed inside the connecting sleeve 32. A first tray 35 is fixedly installed at the end of the first slide rod 34 away from the connecting sleeve 32. A second slide rod 37 is slidably connected to the surface of the end cap 36. A second spring 39 is fixedly installed at the end of the second slide rod 37 near the end cap 36. The end of the second spring 39 away from the second slide rod 37 is fixedly installed inside the end cap 36. A second tray 38 is fixedly installed at the end of the second slide rod 37 away from the end cap 36. A knob 4 is fixedly installed at the end of the end cap 36 away from the second slide rod 37. During the rotation of the shaft 18, which drives the drying tube 3 to rotate, the coal inside the drying tube 3 will move due to gravity to ensure thorough drying and improve drying efficiency. During the coal's movement, it is supported by the first tray 35 and the second tray 38. The first sliding rod 34 and the second sliding rod 37 slide into the connecting sleeve 32 and the end cap 36 respectively, causing the first spring 33 and the second spring 39 to retract for rebound and reset. This effectively reduces the movement speed of the coal inside the drying tube 3, effectively preventing large-area breakage or wear of the coal inside the drying tube 3, which would affect the sample quality. This effectively improves the drying quality of the device and reduces the sample loss rate. When loading the coal to be dried into the drying tube 3, the end cap 36 is first threaded onto one end of the drying tube 3, and then the coal is loaded from the other end of the drying tube 3. During the process, the weight of the coal will gradually cause it to slide into the end cap 36 and cause the second spring 39 to retract. After filling, the other end of the drying tube 3 is threadedly connected to the connecting sleeve 32 fixed on the surface of the mounting sleeve 31 to begin the drying process.

[0030] In one embodiment, the heating assembly includes a plurality of heating tubes 22, and the ventilation assembly includes a fan 12, an air supply duct 13 and a diversion duct 14 connected in sequence from the base 1 toward the drying chamber 11.

[0031] In one embodiment, the ventilation assembly includes multiple air supply pipes 13 and multiple diversion pipes 14. The drying chamber 11 is provided with several partitions 2, which divide the internal space of the drying chamber 11 into several drying spaces. Each drying space is provided with a drying mechanism, and each drying space is connected to at least one diversion pipe 14.

[0032] In one embodiment, the upper surface of the drying chamber 11 is covered by a cover 15, and an exhaust assembly is mounted on the cover 15. The exhaust assembly includes an exhaust fan 17 embedded in the cover 15 and a filter screen 19 disposed below the exhaust fan 17.

[0033] In one embodiment, a dust collection drawer 21 is provided inside the drying chamber 11 below the drying mechanism and is slidably inserted into the drying chamber 11.

[0034] In summary, a rotating shaft 18 is rotatably mounted through the surface of the drying chamber 11. A mounting sleeve 31 is fixedly sleeved on the surface of the rotating shaft 18. A connecting sleeve 32 is fixedly mounted on the surface of the mounting sleeve 31. A drying tube 3 is threaded onto the surface of the connecting sleeve 32. Several heating tubes 22 are provided inside the base 1. A fan 12 is fixedly mounted at the end of the base 1. An air supply pipe 13 is fixedly mounted at the output port of the fan 12. A diversion pipe 14 is connected through the surface of the air supply pipe 13. The diversion pipe 14 is fixedly mounted through the base 1. The output shaft of a motor 23 is fixedly mounted at the end of the rotating shaft 18. The rotating shaft 18 is fixedly mounted on the surface of the drying chamber 11. A dust collection drawer 21 is provided on the surface of the drying chamber 11. The dust collection drawer 21 is slidably mounted inside the drying chamber 11. By placing the coal to be dried inside the drying tube 3, and then starting the motor 23 to drive the rotating shaft 18 to rotate, the coal inside the drying tube 3 will rotate. During the process, the heating tube 22 will generate heat, and the fan 12 will start to deliver the air heated by the heating tube 22 through the air supply pipe 13 and the diversion pipe 14 to the drying chamber 11, thereby completing the drying process of the coal inside the drying tube 3. During the rotation of the drying tube 3, the coal inside can be shaken by gravity, which greatly improves the drying efficiency of the coal. After the coal is dried, the drying tube 3 can be removed from the connecting sleeve 32, and the dried coal can be taken out, which is more convenient to use. At the same time, the coal can be effectively classified according to its size. During the coal drying process, the debris generated can fall into the dust collection drawer 21 by gravity and be collected by the dust collection drawer 21, which makes cleaning more convenient.

[0035] The drying chamber 11 has several partitions 2 fixedly installed inside. The drying tube 3 is set between two partitions 2. The diversion tube 14 is located between two partitions 2. The rotating shaft 18 passes through and rotates on the surface of the partition 2. The dust collection drawer 21 is located below the partition 2.

[0036] By equidistantly arranged partitions 2 inside the drying chamber 11, and by placing the drying pipe 3 and the diversion pipe 14 between two partitions 2, the hot air delivered by the fan 12 to the base 1 can more fully contact the coal inside the drying pipe 3, thereby further improving the coal drying efficiency.

[0037] A cover 15 is hinged to the top of the drying oven 11. A handle 16 is fixedly installed on the top of the cover 15. An exhaust fan 17 is installed through the top of the cover 15. A filter screen 19 is provided at the bottom of the exhaust fan 17. The filter screen 19 is fixedly installed at the bottom of the cover 15 and located inside the drying oven 11. During the coal drying process, the exhaust fan 17 is activated so that the moisture generated by coal evaporation inside the drying chamber 11 can be quickly discharged to the outside of the drying chamber 11, thereby further improving the coal drying efficiency. At the same time, the filter screen 19 filters the gas inside the drying chamber 11, so that the fine particles mixed in the air inside the drying chamber 11 can be filtered and enter the dust collection drawer 21, effectively preventing impurities from being discharged to the outside of the drying chamber 11 and damaging the environment.

[0038] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0039] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
