Description

Technical Field

[0001] The utility model relates to the field of phosphate rock powder production, in particular to a phosphate rock powder sampling device. Background Art

[0002] Phosphate rock is an important chemical mineral raw material, which can be used to make phosphate fertilizer or yellow phosphorus, phosphoric acid, phosphide and other phosphates. Phosphate rock products are widely used in medicine, food, matches, dyes, sugar making, ceramics, national defense and other fields. Phosphate rock is usually in powder form, has no odor, and its main component is fluoroapatite. Phosphate rock powder is generally sampled by a sampling mechanism during the production process.

[0003] In the Chinese patent with publication number CN219573644U, a phosphate rock powder sampling device is mentioned, which is driven by a telescopic cylinder to reciprocate the slide plate. During the reciprocating motion, the phosphate rock powder can be quantitatively fed into the discharge pipe and discharged into the barrel, and the amount of phosphate rock powder fed into the barrel each time is guaranteed to be consistent, which not only ensures the sampling accuracy, but also can be adapted to the sampling of buried scraper conveyors. However, the phosphate rock in the barrel has a certain depth, and the phosphate rock in different layers above and below cannot be guaranteed to be uniform. This phosphate rock powder sampling device can only sample the samples of the lowest layer, which is not convenient for sampling samples of different depths of phosphate rock powder, resulting in inaccurate sampling results. The detection results are quite different from the actual situation, and the practicality is insufficient. Utility Model Content

[0043] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0044] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1-4 This embodiment provides a phosphate rock powder sampling device, which mainly includes: a phosphate rock powder box 100 and three sampling mechanisms 200.

[0046] like Figure 1 , Figure 2 As shown in the figure, the mineral powder box 100 is a box used to hold phosphate rock powder during the transportation of phosphate rock powder. A feed hopper 160 is inserted and fixedly connected to the middle of the top wall of the mineral powder box 100 for phosphate rock powder to enter. The end of the feed hopper 160 extending out of the mineral powder box 100 is its expanded bucket part, which has a thread at the upper end, and a sealing cover 180 detachably threadedly connected to it is arranged on the top. At the same time, the four corners below the bottom of the mineral powder box 100 are fixedly connected to support feet 140, and the lower ends of the four support feet 140 are fixedly connected to the anti-slip seat 120. In addition, three card slots 121 are opened on the left, middle and right positions on the upper surface of the anti-slip seat 9 towards the bottom of the mineral powder box 100, and the three card slots 121 are all clamped with a receiving barrel 122 facing the bottom of the mineral powder box 100, which is used to hold the taken out phosphate rock powder samples.

[0047] like Figure 3 , Figure 4As shown in the figure, the three sampling mechanisms 200 are respectively a short material taking mechanism 2001, a middle material taking mechanism 2002 and a long material taking mechanism 2003, which are used to take out the phosphate rock powder at different depths in the mineral powder box 100. Among them, each sampling mechanism 200 is composed of a material taking barrel 220 and a spiral feeding member 240. The main cylindrical part of the material taking barrel 220 is arranged vertically, the upper end of the main part is open for feeding, and the lower end is closed. A downwardly inclined discharge barrel 224 is inserted and fixedly connected through the lower front end of the main body as an outlet for the obtained phosphate rock powder sample. A valve 226 is arranged inside the discharge barrel 224, which can be closed when no sampling is performed to prevent the phosphate rock powder from leaking out. The spiral feeding member 240 is inserted and movably connected inside the main part of the material taking barrel 220, and the spiral feeding member 240 includes a central feeding shaft 242, and a feeding blade 632 spirally arranged from top to bottom on the side of the feeding shaft 242. The lower end of the feeding shaft 242 passes through the bottom of the material taking barrel 220 and is movably connected to the bottom of the material taking barrel 220 through a bearing, but the feeding blade 632 is only arranged inside the material taking barrel 220. The spiral feeding member 240 stirs the phosphate rock powder in the material taking barrel 220 and guides it to move downward to the discharge barrel 224 for discharge. At the same time, the short feeding mechanism 2001 of the sampling mechanism 200 is vertically inserted and fixedly connected to the left position on the bottom wall of the mineral powder box 100; the middle feeding mechanism 2002 is vertically inserted and fixedly connected to the middle position on the bottom wall of the mineral powder box 100; and the long feeding mechanism 2003 is vertically inserted and fixedly connected to the right position on the bottom wall of the mineral powder box 100. Furthermore, the length of one end of the short material taking mechanism 2001, the middle material taking mechanism 2002 and the long material taking mechanism 2003 extending into the mineral powder box 100 is increased in sequence, and the discharge barrels 224 of one end of the short material taking mechanism 2001, the middle material taking mechanism 2002 and the long material taking mechanism 2003 extending out of the mineral powder box 100 are respectively opposite to the three receiving barrels 122, so that the samples taken out at different depths are respectively output to the three receiving barrels 122. The upper end surfaces of the three receiving barrels 122 are all lower than the lower end surface of the discharge barrel 224, so that the receiving barrel 122 can be taken out from the card slot 121.

[0048] A specific implementation of this embodiment is as follows: first, three receiving barrels 122 are inserted into the three clamping grooves 121 of the anti-slip seat 120 for clamping and fixing, so that the receiving barrels 122 are just located below the discharging barrel 224 for easy sample collection. Next, the valve 226 on the discharging barrel 224 is opened. Then, the lower ends of the feeding shafts 242 of the short feeding mechanism 2001, the middle feeding mechanism 2002 and the long feeding mechanism 2003 are rotated in sequence to pass through the bottom of the feeding barrel 220, so that the feeding shaft 242 drives the feeding blade 244 to rotate, so that the phosphate rock powder in the mineral powder box 100 can enter the feeding barrel 220 and be discharged through the discharging barrel 224, so as to realize the sampling of the phosphate rock powder. And by setting the short feeding mechanism 2001, the middle feeding mechanism 2002 and the long feeding mechanism 2003 of different lengths, the sampling of the phosphate rock powder at different depths in the mineral powder box 100 is realized. Finally, the valve 226 is closed, and the three receiving barrels 122 are removed, and the samples therein are tested, and the test results are averaged.

[0049] In this embodiment, the phosphate rock powder sampling device realizes sampling of different depths of phosphate rock powder by setting three material taking mechanisms 200 of different lengths, and the taken samples are more uniform, so that the sampling results are more representative, more in line with reality, and the test results are more accurate. This solves the problem that the phosphate rock powder sampling device in the prior art can only sample the samples of the lowest layer, resulting in inaccurate sampling results, a large gap between the test results and the actual situation, and insufficient practicality.

[0050] At the same time, in this embodiment, a spiral feed member 240 with a feed shaft 242 and feed blades 244 is provided, and the phosphate rock powder is loosened by the action of the rotating stirring force, so that it is easy to fall into the material taking barrel 220 and be discharged downward, thereby overcoming the disadvantage that the phosphate rock powder in the mineral powder box 100 is easy to stick together and difficult to fall, and realizing convenient and quick removal of the phosphate rock powder sample from the mineral powder box 100.

[0051] Preferably, in this embodiment, a fixing ring 222 may be provided on the outer wall of the material taking barrel 220. The material taking barrel 220 is provided with two upper and lower fixing rings 222, which are respectively provided on the inner and outer sides of the bottom wall of the mineral powder box 100. The spacing between the two fixing rings 222 is equal to the thickness of the bottom wall of the mineral powder box 100, so that the material taking barrel 220 is just engaged with the bottom wall, thereby preventing the material taking barrel 220 from loosening and phosphate rock powder from leaking from its side, thereby causing the device to fail. By providing the fixing ring 222, the firmness and durability of the device are improved.

[0052] In addition, in this embodiment, the anti-slip seat 120 can be slidably arranged under the mineral powder box 100, and the anti-slip seat 120 can be slid and pulled out from the four supporting legs 140. With this design, after taking materials in the process of use, when it is necessary to remove the three material receiving barrels 122 to inspect the samples therein, the anti-slip seat 120 can be slid first to be pulled out from under the mineral powder box 100, so that the obstruction of the upper material taking barrel 220 is avoided during the removal of the three material receiving barrels 122, and it is easier to remove.

[0053] However, in the above embodiment, since the three sampling mechanisms 200 take samples separately, on the one hand, three operations are required, which increases the workload and reduces the sampling efficiency; on the other hand, the sample amounts in each discharge barrel 224 are not equal, which also causes the problem of uneven sampling between different depths. In order to further solve these problems on the basis of the first embodiment, a second embodiment is provided below.

[0054] See also Figure 1-4 The phosphate rock powder sampling device in the second embodiment mainly includes a first gear 300, a second gear 246 and a fixing frame 400.

[0055] like Figure 2-Figure 4 As shown in FIG, three second gears 246 are respectively fixedly arranged at the lower ends of the feeding shafts 242 of the three sampling mechanisms 200 and pass through the bottom of the material taking barrel 220, and can drive the three spiral feeding members 240 to rotate by rotating. The two first gears 300 are respectively meshed with the two second gears 246, and as shown in FIG. Figure 2 As shown, a structure is formed in which five gears mesh in sequence, and the rotation of any one gear can drive the five gears to rotate synchronously.

[0056] like Figure 1 , Figure 2As shown in , the fixing frame 400 is fixed between the lower left part and the lower right part of the bottom of the mineral powder box 100, and between the anti-slip seat 120 and the four upper support legs 140, and is used to fix the transmission structure of the above five gears. On the one hand, the horizontal plate part of the fixing frame 400 is movably connected with the lower ends of the feed shafts 242 of the three sampling mechanisms 200 through the embedded bearings to fix the position of the second gear 246. On the other hand, the horizontal plate part of the fixing frame 400 is movably connected with two shaft bodies 420 through bearings, and the upper ends of the two shaft bodies 420 are movably connected with the bottom wall of the mineral powder box 100 through bearings, and the lower ends of the two shaft bodies 420 are fixedly connected with handles 422, and the middle parts of the two shaft bodies 420 and the position above the horizontal plate part of the fixing frame 400 are inserted and fixedly connected with the first gear 300 to fix the position of the first gear 300. When in use, first rotate the handle 422 to drive the shaft 420 to rotate, and the shaft 420 then drives the first gear 300 thereon to rotate, and then through the meshing transmission of the first gear 300 and the two second gears 246, multiple rotations can be achieved simultaneously by rotating one place, that is, the three material taking mechanisms can work simultaneously for sampling.

[0057] In this embodiment, the phosphate rock powder sampling device is provided with a transmission system composed of a first gear 300, a second gear 246 and a fixed frame 400. The rotation of a handle 422 can drive the three spiral feeders 240 to rotate synchronously, and the sampling of the three sampling mechanisms starts and ends synchronously, thereby achieving synchronous sampling of phosphate rock powder at three locations, improving sampling efficiency and reducing workload. At the same time, the sampling at the three locations starts and stops at the same time, and the sampling volume can be kept basically the same, which also solves the problem of uneven sampling between different depths in the above embodiment, and further improves the uniformity and accuracy of sampling of the device.

[0058] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
