Abstract
Description
Technical Field
[0001] This utility model relates to the field of total moisture testing technology, and in particular to a reduction device for total moisture testing. Background Technology
[0002] As a heterogeneous material, the moisture distribution of coal is significantly affected by particle size, pore structure and storage environment. In the total moisture test of coal, it is necessary to reduce the coal sample to the gram-level sample required by the laboratory by scientifically reducing the original large coal sample. At the same time, the moisture distribution characteristics of the original coal are preserved.
[0003] Existing sample reduction mechanisms (such as Chinese patent document with publication number CN119044516A) typically discard the remaining sample after reduction directly through a waste hopper or waste conveyor belt. If this method is used in a fully automated moisture testing system, it is difficult to trace the source when abnormal test results occur, and sample moisture data is easily missing, resulting in low accuracy. Utility Model Content
[0004] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a compact, sample-saving, and highly accurate sample reduction device for total moisture testing.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A sample reduction device for total moisture testing includes a material conveying line, a transfer mechanism, and a feeding mechanism, a reduction mechanism, and a residual sample receiving mechanism arranged sequentially along the material conveying line. The feeding mechanism is used to feed the sample from the sample bottle onto the material conveying line. The reduction mechanism is used to reduce the sample on the material conveying line, and the remaining sample after reduction is conveyed by the material conveying line to the residual sample receiving mechanism. The transfer mechanism is used to transfer the empty sample bottle after feeding to the residual sample receiving mechanism to recover the remaining sample on the material conveying line.
[0007] As a further improvement to the above technical solution:
[0008] The feeding mechanism includes a feeding hopper and a pouring assembly. The feeding hopper is located above the material conveying line, and the pouring assembly is used to pour the sample from the sample bottle into the feeding hopper.
[0009] The dispensing assembly includes a rotary drive, a dispensing frame, sample bottle grippers and a striking component mounted on the dispensing frame. The rotary drive is mounted on the feed hopper, and its output end is connected to the dispensing frame. The striking component is located below the sample bottle grippers.
[0010] The material pouring rack is also equipped with a counterweight, and the counterweight and sample bottle grippers are located on both sides of the rotating drive component.
[0011] A rectifier is also provided between the feeding mechanism and the dividing mechanism. The rectifier includes a height limiting plate, and a rectifier channel is formed between the height limiting plate and the material conveying line. There is also a rectifier stirring component upstream of the height limiting plate.
[0012] The reduction mechanism includes a circulating conveyor line located above the material conveyor line. The conveying direction of the material conveyor line is perpendicular to the conveying direction of the circulating conveyor line. The circulating conveyor line is equipped with a scraper, which is used to circulate and convey the scraper to intermittently scrape the sample flow off the material conveyor line.
[0013] The material conveying line is provided with a partition plate below the circulating conveying line. The partition plate is aligned with the center line of the scraper. The partition plate is provided with a discharge pipe on both sides, and the bottom of the discharge pipe is provided with a receiving tray.
[0014] The residual sample receiving mechanism includes a discharge hopper located below the end of the material conveying line, a bracket located below the discharge hopper, a lifting drive component connected to the bottom of the bracket, and a weighing sensor located on the bracket.
[0015] The material conveying line includes an upper conveying line and a lower conveying line located below the upper conveying line. The upper conveying line and the lower conveying line have opposite conveying directions. The feeding mechanism and the shrinking mechanism are located above the upper conveying line, and the sample receiving mechanism is located below the end of the lower conveying line.
[0016] The sample reduction device for total moisture testing also includes a housing, the material conveying line is installed inside the housing, the feeding mechanism and the sample reduction mechanism are installed on the top of the housing, and the sample receiving mechanism is installed at the bottom of the housing.
[0017] Compared with the prior art, the advantages of this utility model are:
[0018] 1. The sample reduction device for total moisture testing of this utility model can ensure that the sample is not wasted by collecting the remaining sample through the sample receiving mechanism. When the test results are abnormal, it is easy to trace the source and the test results are highly accurate. The sample bottle is transferred from the feeding mechanism to the remaining sample mechanism for sample recycling through the transfer mechanism. The sample bottle can be reused. The structure is compact and the cost is low.
[0019] 2. The sample reduction device for total moisture testing of this utility model, during feeding, the sample bottle clamps tighten the sample bottle, and the rotating drive drives the sample bottle to rotate so that the opening of the sample bottle faces the feeding hopper, pouring the sample into the feeding hopper. At the same time, the striking component taps the bottom of the sample bottle to reduce sample residue, resulting in higher test accuracy.
[0020] 3. The reducing device for total moisture testing of this utility model has a counterweight that can balance the weight of the sample bottle and the sample, eliminate the impact when the sample bottle is flipped, and make the device more stable, which is conducive to extending the life of the device.
[0021] 4. The sample reduction device for total moisture testing of this utility model controls the sample flow height through a height limiting plate. When the sample passes through the rectification mechanism, it forms a sample flow with a fixed height and width, which facilitates accurate subsequent reduction ratio. The rectifier stirs the sample in front of the rectification channel to prevent the sample from clogging at the rectification channel.
[0022] 5. The reducing device for total moisture testing of this utility model has the following characteristics: since the conveying direction of the material conveying line is perpendicular to the conveying direction of the circulating conveying line, when the scraper passes through the reducing mechanism, the scraper scrapes the sample flow off the material conveying line. By controlling the running speed of the material conveying line and the circulating conveying line, the reducing ratio can be adjusted.
[0023] 6. The sample reduction device for total moisture testing of this utility model divides the sample scraped off by the scraper into two parts through a partition plate. The scraped samples fall into two receiving trays through two drop pipes, and are parallel samples. The two samples can be used to verify the results of each other, resulting in higher test accuracy.
[0024] 7. The sample reduction device for total moisture testing of this utility model, after the sample bottle on the residual sample receiving mechanism has received the residual sample, the lifting drive component drives the sample bottle to descend, and then the external equipment transfers it to complete the residual sample recovery; since the bracket is equipped with a weighing sensor, the sample bottle can be transferred in time before it is full.
[0025] 8. The sample reduction device for total moisture testing of this utility model, after the sample is transported to the end of the upper conveyor line, falls to the beginning of the lower conveyor line, and is then transported by the lower conveyor line to the end of the lower conveyor line, falling into the sample receiving mechanism. Since the upper and lower conveyor lines are transported in opposite directions, the upper and lower conveyor lines can be arranged vertically, resulting in a compact structure. Furthermore, the sample receiving mechanism can be located below the feeding mechanism, which facilitates the transfer mechanism to transfer the sample bottles, resulting in a reasonable layout.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] like Figures 1 to 5 As shown, the sample reduction device for total moisture testing in this embodiment includes a material conveying line 1, a transfer mechanism, and a feeding mechanism 2, a reduction mechanism 3, and a residual sample receiving mechanism 4 arranged sequentially along the material conveying line 1. The feeding mechanism 2 is used to feed the sample in the sample bottle 9 onto the material conveying line 1. The reduction mechanism 3 is used to reduce the sample on the material conveying line 1, and the remaining sample after reduction is continued to be transported by the material conveying line 1 to the residual sample receiving mechanism 4. The transfer mechanism (not shown in the figure, such as a transfer robot) is used to transfer the empty sample bottle 9 after feeding to the residual sample receiving mechanism 4 to recover the remaining sample on the material conveying line 1.
[0037] In this embodiment, the sample reduction device for total moisture testing operates by loading sample bottles 9 containing samples onto the feeding mechanism 2. The feeding mechanism 2 feeds the sample from sample bottles 9 onto the material conveying line 1. The transfer mechanism then transfers the empty sample bottles 9 to the residual sample receiving mechanism 4. The reduction mechanism 3 reduces the sample on the material conveying line 1, and the reduced residual sample is then conveyed to the empty sample bottles 9 on the residual sample receiving mechanism 4, completing the sample reduction and residual sample recovery. This embodiment's total moisture testing reduction device, through the residual sample receiving mechanism 4, ensures no sample waste and facilitates traceability when test results are abnormal, resulting in high test accuracy. The transfer mechanism allows for the reuse of sample bottles 9, making the device compact and cost-effective.
[0038] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the feeding mechanism 2 includes a feeding hopper 21 and a pouring assembly 22. The feeding hopper 21 is located above the material conveying line 1, and the pouring assembly 22 is used to pour the sample from the sample bottle 9 into the feeding hopper 21. When the sample bottle 9 containing the sample is loaded onto the feeding mechanism 2, the pouring assembly 22 tilts the sample bottle 9 downwards and pours the sample from the sample bottle 9 into the feeding hopper 21. The structure is simple and reliable.
[0039] Furthermore, such as Figure 5 As shown, in this embodiment, the pouring assembly 22 includes a rotation drive 224, a pouring rack 221, and sample bottle grippers 222 and a striking element 223 mounted on the pouring rack 221. The rotation drive 224 is mounted on the feeding hopper 21, and its output end is connected to the pouring rack 221. The striking element 223 is located below the sample bottle grippers 222. During feeding, the sample bottle grippers 222 clamp the sample bottle 9, and the rotation drive 224 (e.g., a motor) drives the sample bottle 9 to rotate, so that the opening of the sample bottle 9 faces the feeding hopper 21, pouring the sample into the feeding hopper 21. At the same time, the striking element 223 (e.g., a hammer) strikes the bottom of the sample bottle 9, reducing sample residue and improving the accuracy of the test results.
[0040] Preferably, in this embodiment, the feed hopper 21 is provided with an auxiliary support, one end of the pouring frame 221 is connected to the output end of the rotation drive 224, and the other end is rotatably connected to the auxiliary support, so that the pouring frame 221 is more stable when it is flipped.
[0041] Furthermore, in this embodiment, the pouring rack 221 is also provided with a counterweight 225, and the counterweight 225 and the sample bottle gripper 222 are respectively located on both sides of the rotation drive 224. The counterweight 225 can balance the weight of the sample bottle 9 and the sample, eliminate the impact when the sample bottle 9 is overturned, improve the stability of the device, and help extend the life of the device.
[0042] Preferably, such as Figure 2 As shown, in this embodiment, the feed hopper 21 is equipped with a feed agitator 211. After the sample is poured into the feed hopper 21, the agitator 211 can uniformly agitate the sample, reducing the selectivity deviation during sample reduction.
[0043] Furthermore, such as Figure 2 As shown in this embodiment, a rectification mechanism 5 is also provided between the feeding mechanism 2 and the reduction mechanism 3. The rectification mechanism 5 includes a height limiting plate 51, which forms a rectification channel with the material conveying line 1. A rectification stirring component 52 is also provided upstream of the height limiting plate 51. The height of the sample flow is controlled by the height limiting plate 51. When the sample passes through the rectification mechanism 5, a sample flow with a fixed height and width is formed, which facilitates accurate subsequent reduction ratio. The rectification stirring component 52 stirs the sample in front of the rectification channel to prevent the sample from clogging at the rectification channel.
[0044] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the reduction mechanism 3 includes a circulating conveyor line 31 located above the material conveyor line 1. The conveying direction of the material conveyor line 1 is perpendicular to the conveying direction of the circulating conveyor line 31. A scraper 32 is provided on the circulating conveyor line 31, which is used to circulate and convey the scraper 32 to intermittently scrape the sample flow off the material conveyor line 1. Since the conveying direction of the material conveyor line 1 is perpendicular to the conveying direction of the circulating conveyor line 31, when the scraper 32 circulates and conveys the sample flow off the material conveyor line 1, the scraper 32 scrapes the sample flow off the material conveyor line 1. By controlling the running speed of the material conveyor line 1 and the circulating conveyor line 31, the reduction ratio can be adjusted.
[0045] Preferably, in this embodiment, the circulating conveyor line 31 includes a pair of conveyor chains arranged at intervals, and the scraper 32 is connected between the pair of conveyor chains, which has a simple and reliable structure.
[0046] Furthermore, in this embodiment, a partition plate 33 is provided below the circulating conveyor line 31 in the material conveyor line 1. The partition plate 33 is aligned with the center line of the scraper 32. A drop pipe 34 is provided on both sides of the partition plate 33, and a receiving tray 35 is provided at the bottom of the drop pipe 34. The sample scraped off by the scraper 32 is divided into two parts by the partition plate 33. The scraped samples fall into two receiving trays 35 through the two drop pipes 34 respectively, and are parallel samples. The two samples can be used to verify the results, resulting in higher test accuracy.
[0047] Furthermore, such as Figure 2 As shown, in this embodiment, the residual sample receiving mechanism 4 includes a discharge hopper 41 located below the end of the material conveying line 1. A bracket 42 is located below the discharge hopper 41, and a lifting drive component 43 is connected to the bottom of the bracket 42. A weighing sensor is installed on the bracket 42. After the sample bottle on the residual sample receiving mechanism 4 has received all the residual sample, the lifting drive component 43 (e.g., a lifting cylinder) drives the sample bottle to descend, and then it is transferred by external equipment to complete the residual sample recovery. Because the bracket 42 is equipped with a weighing sensor, the sample bottle can be transferred in time before it is full.
[0048] Furthermore, such as Figure 2 As shown, in this embodiment, the material conveying line 1 includes an upper conveying line 11 and a lower conveying line 12 located below the upper conveying line 11. The conveying directions of the upper conveying line 11 and the lower conveying line 12 are opposite. The feeding mechanism 2 and the reducing mechanism 3 are located above the upper conveying line 11, and the sample receiving mechanism 4 is located below the end of the lower conveying line 12. After the sample is conveyed to the end of the upper conveying line 11, it falls to the beginning of the lower conveying line 12, and then is conveyed by the lower conveying line 12 to its end, falling into the sample receiving mechanism 4. Since the conveying directions of the upper conveying line 11 and the lower conveying line 12 are opposite, the upper conveying line 11 and the lower conveying line 12 can be arranged vertically, resulting in a compact structure. Furthermore, the sample receiving mechanism 4 can be located below the feeding mechanism 2 (preferably, the sample receiving mechanism 4 is located directly below the feeding mechanism 2), which facilitates the transfer of sample bottles by the transfer mechanism, resulting in a reasonable layout.
[0049] Furthermore, such as Figure 1 As shown, in this embodiment, the sample reduction device for total moisture testing also includes a housing 6, a material conveying line 1 installed inside the housing 6, a feeding mechanism 2 and a sample reduction mechanism 3 installed on the top of the housing 6, and a sample receiving mechanism 4 installed at the bottom of the housing 6. The material conveying line 1 is installed inside the housing 6, while the feeding mechanism 2, the sample reduction mechanism 3, and the sample receiving mechanism 4 are installed outside the housing 6, resulting in a well-integrated device with a simple and compact structure.
[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model using the methods and techniques disclosed above, or modify it into equivalent embodiments with equivalent changes, without departing from the spirit and technical solution of the present utility model. Therefore, any simple modifications, equivalent substitutions, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
