AI Technical Summary
In existing technologies, it is difficult to accurately control the paving thickness of coal paving devices, especially for coal with high moisture content, which can easily lead to excessive thickness during transportation, affecting the drying effect.
A baffle extending along the conveyor belt forms an opening with the conveyor belt, which enables the coal to be evenly spread. The baffle restricts the range of coal movement, ensuring that the coal is gradually decomposed and spread during the transportation process.
This method achieves effective coal spreading, improves drying efficiency and equipment reliability, and avoids the problem of excessive thickness caused by coal with high moisture content.

TECHNICAL FIELD
[0001] The present disclosure relates to the field of coal sample preparation technology equipment, in particular, to a coal sample preparation conveying device and a coal sample preparation device. BACKGROUND
[0002] Coal sample preparation is a process of processing a large amount of large-size coal samples into samples of a specified size and quality through crushing, size reduction, and other procedures.
[0003] The coal sample preparation process generally includes cutting the coal sample by a belt size reducer on a first conveying belt after the coal is crushed, dropping the cut coal sample into a second conveying belt through a discharging device, conveying the coal sample to a drying device by the second conveying belt, and then entering the sample receiving groove after drying, and finally uniformly conveying to the grinding bowl, and then falling into the coal powder receiver after grinding and screening.
[0004] In related technologies, the coal spreading device generally includes a support frame connected to the conveying belt and a hopper hinged to the support frame. By adjusting the discharging time of the hopper and the opening size of the hopper through a preset program, the discharging amount is adjusted, and then the movement of the conveying belt is matched to achieve the spreading of the coal. However, this method is not easy to accurately control the spreading thickness of the coal. If the coal has a high moisture content, it cannot be effectively spread by the movement of the conveying belt after falling into the conveying belt, which may eventually result in the coal having a large thickness and poor drying effect after entering the drying device. CONTENT OF THE INVENTION
[0005] The purpose of the present disclosure is to provide a coal sample preparation conveying device and a coal sample preparation device, which can effectively spread the coal to at least partially solve the above technical problems.
[0006] To achieve the above purpose, the first aspect of the present disclosure provides a coal sample preparation conveying device, comprising:
[0007] a conveying belt for conveying coal, the conveying belt being provided with a fixed structure on each of the opposite sides in the first direction; and
[0008] a spreading mechanism including a partition plate extending along the first direction and connected between the two fixed structures, the partition plate being located above the conveying belt, the partition plate and the conveying belt forming a pass opening for the coal to pass through, and the partition plate being used to spread the coal on the conveying belt
[0009] Optionally, the fixed structure includes a fixed plate extending in the conveying direction of the conveying belt and a fixed portion provided on the fixed plate, and the opposite ends of the partition plate are respectively connected to the fixed portions of the two fixed structures.
[0010] Optionally, the paving mechanism further comprises two baffles connected to opposite ends of the partition plate along the first direction, so that the partition plate and the two baffles jointly form a containing space for containing coal.
[0011] Optionally, the extending length of the partition plate along the first direction is less than the extending length of the conveying belt along the first direction.
[0012] Optionally, the baffle is further provided with a matching part detachably connected to the fixed part.
[0013] Optionally, the number of the fixed parts and the matching parts is multiple, and the multiple fixed parts are arranged at intervals along the conveying direction, and the multiple matching parts correspond to the multiple fixed parts one by one.
[0014] In a second aspect of the present disclosure, a coal sample preparation device is provided, comprising:
[0015] The conveying device in any of the above optional solutions;
[0016] The discharging device comprises a discharging cylinder and a coal conveying mechanism for conveying coal to the discharging cylinder.
[0017] The drying device is arranged on the first side of the conveying device along the conveying direction, and is used for dehydrating and drying the coal passing through the passageway on the conveying belt.
[0018] Optionally, the coal sample preparation device further comprises a housing covering the outside of the conveying device, and the discharging cylinder is connected to the top wall of the housing and communicates with the inside of the housing.
[0019] Optionally, the housing comprises a bottom plate, two side plates connected to the bottom plate and arranged oppositely along the first direction, and a top plate detachably connected to the two side plates, or the fixed structure forms the side plates.
[0020] Optionally, the discharging cylinder comprises a feeding port for feeding coal.
[0021] Through the above technical solution, the partition plate extending along the first direction is arranged, and the partition plate and the conveying belt form a passageway for the coal to pass through. The coal passing through the passageway can be evenly paved on the conveying belt. Even if the cake-shaped coal with large water content and adhesion is encountered, the partition plate can intercept the cake-shaped coal and gradually decompose and pave the cake-shaped coal through the continuous movement of the conveying belt. Therefore, the conveying device provided by the present disclosure can effectively pave the coal, has better effect, and has better reliability and stability in use.

[0033] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0034] In the present disclosure, "inner and outer" refer to the inner and outer of the profile of the corresponding components, and in addition, the terms "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance, and in addition, the following description refers to the drawings, and unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0035] According to Figures 1 to 4As shown, in a first aspect of the present disclosure, a conveying device for coal sample preparation is provided, which is used for conveying coal from a discharging device and to be conveyed to a drying device 3. The conveying device can include a conveying belt 100 for conveying coal, and a spreading mechanism. The conveying belt 100 is provided with a fixed structure on each of the opposite sides in a first direction X. The spreading mechanism can include a partition plate 102 extending in the first direction X and connected between the two fixed structures. The partition plate 102 is located above the conveying belt 100, and forms a pass opening between the partition plate 102 and the conveying belt 100 for the coal to pass through. The partition plate 102 is used to spread the coal on the conveying belt 100.
[0036] Through the above technical solution, the partition plate 102 extending in the first direction X forms a pass opening between the partition plate 102 and the conveying belt 100 for the coal to pass through. The coal passing through the pass opening can be evenly spread on the conveying belt 100, and the spreading effect is better. Even if the cake-shaped coal with larger moisture content and adhesion is encountered, the partition plate 102 can intercept the cake-shaped coal, and gradually decompose and spread the cake-shaped coal through the continuous movement of the conveying belt 100, which has better reliability and stability in use.
[0037] In some embodiments, the conveying direction Y can be a direction towards the first side of the conveying device; and the first direction X can be a direction perpendicular to the conveying direction Y.
[0038] It should be noted that the pass opening formed between the partition plate 102 and the conveying belt 100 can be formed by the gap between the conveying belt 100 and the partition plate 102 located above the conveying belt 100.
[0039] The height of the partition plate 102 in the vertical direction should be adjusted according to the conveying speed of the conveying belt 100 of the conveying device and the coal conveying mechanism 21 of the discharging device. For example, if the conveying speed of the coal conveying mechanism 21 of the discharging device is greater than the conveying speed of the conveying belt 100 of the conveying device, it is easy to cause the discharging device to convey too much coal per second. When the excessive coal falls onto the conveying belt 100 of the conveying device with a relatively slow speed, the excessive coal will be stacked after contacting the partition plate 102. If the height of the partition plate 102 in the vertical direction is not enough, the coal will overflow the partition plate 102. Therefore, the height of the partition plate 102 should be adjusted according to the actual situation by the person skilled in the art. The present disclosure does not make specific limitations on this.
[0040] In some embodiments, for example, with reference to Figures 2 to 4As shown, the fixing structure can include a fixing plate 101 extending along the conveying direction Y of the conveying belt 100 and a fixing portion 103 arranged on the fixing plate 101, and the opposite ends of the partition plate 102 are respectively connected to the fixing portions 103 of the two fixing structures. By arranging the fixing plate 101, the conveying belt 100 can be further fixed, so that the conveying belt 100 is more stable during operation. The fixing portion 103 arranged on the fixing plate 101 can facilitate the installation and disassembly of the partition plate 102, and is more convenient.
[0041] In some embodiments, for example, referring to Figures 2 to 4 As shown, the paving mechanism can further include two baffle plates 104 connected to the opposite ends of the partition plate 102 along the first direction X, so that the partition plate 102 and the two baffle plates 104 together enclose a containing space 105 for containing coal. After the coal contacts the partition plate 102, the coal that has not passed through the gap will move along the opposite sides of the first direction X towards the partition plate 102 under the continuous operation of the conveying belt 100. By arranging the two baffle plates 104, the movement range of the coal on the conveying belt 100 is limited. Of course, the size of the gap formed between the two baffle plates 104 and the conveying belt 100 should be the same as the size of the gap, so that the coal passing through the gap can also be evenly paved.
[0042] In some embodiments not shown, the paving mechanism can further include a limiting plate connected to the partition plate 102 and the two baffle plates 104 and located above the baffle plates 104 and the partition plate 102, to solve the problem that too much coal will overflow the partition plate 102. The present disclosure is not limited to this, and those skilled in the art can make adaptive adjustments according to actual needs.
[0043] Optionally, the extension length of the partition plate 102 in the first direction X can be less than the extension length of the conveying belt 100 in the first direction X, to further limit the movement range of the coal and avoid the coal from directly falling to the ground when passing through the gap between the baffle plate 104 and the conveying belt 100 and / or passing through the gap, to further improve the reliability of use.
[0044] In some embodiments, for example, referring to Figures 2 to 4 As shown, the baffle plate 104 can further be provided with a matching portion 106 detachably connected to the fixing portion 103. By means of detachable connection, the paving mechanism can be replaced and maintained more conveniently and more conveniently.
[0045] The structure of the fixing part 103 and the matching part 106 can be adjusted adaptively according to actual needs, for example, the fixing part 103 can be configured as a mounting block with a threaded hole, the matching part 106 can be configured as a mounting block with a through hole, and the two mounting blocks are fixedly connected by a bolt, or the fixing part 103 can also be configured as a clamping groove, and the matching part 106 can be configured as a clasp. The present disclosure does not make specific limitations in this regard.
[0046] The number of the fixing part 103 and the matching part 106 can be multiple, multiple fixing parts 103 can be arranged at intervals along the conveying direction Y, and multiple matching parts 106 correspond to multiple fixing parts 103 one by one. By arranging multiple fixing parts 103 and multiple matching parts 106, the paving mechanism can be more stable, for example, the number of the fixing part 103 and the matching part 106 can be four, or six or eight. The present disclosure does not make specific limitations in this regard.
[0047] As described above, when the fixing part 103 is configured as a mounting block with a threaded hole and the matching part 106 is configured as a mounting block with a through hole, the operator can add a gasket between the fixing part 103 and the matching part 106 to adjust the size of the gap between the baffle 102 and the conveying belt 100, and the gap between the two baffles 104 and the conveying belt 100. The present disclosure does not make specific limitations in this regard.
[0048] Optionally, the baffle 102 and the two baffles 104 can be configured as a whole to reduce the processing process and save economic cost.
[0049] In a second aspect, the present disclosure provides a coal sample preparation device, for example, referring to Figures 1 to 4 The sample preparation device can include a conveying device, a discharging device, and a drying device 3. The conveying device has all the beneficial effects in the above specific embodiments, and the present disclosure will not be repeated here. The discharging device can include a discharging cylinder 20 and a coal conveying mechanism 21 for conveying coal to the discharging cylinder 20. The drying device 3 is arranged on the first side of the conveying device along the conveying direction Y, and the drying device 3 is used for dehydrating and drying the coal passing through the gap on the conveying belt 100.
[0050] In some implementable ways, for example, referring to Figures 1 to 4 The coal sample preparation device can further include a housing 4 covering the outside of the conveying device. The discharging cylinder 20 is connected to the top wall of the housing 4 and communicates with the inside of the housing 4. In this way, the housing 4 can protect the coal on the conveying belt 100 from external pollutants.
[0051] Optionally, the shell 4 can comprise a bottom plate 400, two side plates 401 connected to the bottom plate 400 and arranged oppositely along the first direction X, and a top plate 402 detachably connected to the two side plates 401, or the fixed structure can form the side plates 401 to reduce the processing technology and reduce the cost. By arranging the top plate 402 detachably connected to the side plates 401, the operator can open the top plate 402 when performing maintenance and repair, and timely adjust the conveying device inside the shell 4.
[0052] The detachable connection between the side plate 401 and the top plate 402 can be through bolt connection, or through latch or claw connection. The present disclosure is not limited thereto, and those skilled in the art can make adjustments according to the actual needs.
[0053] Optionally, the feeding cylinder 20 can comprise a feeding port 200 for feeding coal, and the opening size of the feeding port 200 can be greater than or equal to the size of the coal conveying mechanism 21, so as to avoid coal falling to the ground during the coal conveying process and causing environmental pollution.
[0054] The structure of the feeding cylinder 20 can be adaptively adjusted according to the actual needs, for example, the feeding cylinder 20 can be constructed as a cylindrical cylinder with an open side wall, and the opening forms the feeding port 200, or it can also be constructed as a cylindrical cylinder with an open top wall. The present disclosure does not make specific limitations thereto.
[0055] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments, and various simple modifications can be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
[0056] In addition, it should be noted that various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not make further description on various possible combination manners.
[0057] In addition, various different embodiments of the present disclosure can also be combined in any appropriate manner, as long as they do not deviate from the idea of the present disclosure, they should also be considered as disclosed by the present disclosure.
