Description

Technical Field

[0001] This utility model belongs to the field of coal sampling technology, and in particular relates to a coal testing sample collection device. Background Technology

[0002] The collection of coal samples in coal testing is a meticulous and standardized process. Coal sampling is a process of taking a representative portion of coal from a whole batch of coal according to regulations. This process needs to follow certain specifications or requirements, such as collecting a certain number of samples from the ore body, surrounding rock, and products produced by the mine (such as raw ore, concentrate, tailings, slag, etc.).

[0003] Because the particle size of the collected samples far exceeds that of the coal samples used in the laboratory, they must be crushed to reduce the particle size. Therefore, after the sampling is completed, the samples need to be taken out and crushed again, which is cumbersome and increases the workload.

[0004] Therefore, a coal testing sample collection device is proposed. Utility Model Content

[0005] This invention provides a coal testing sample collection device, which aims to solve the above-mentioned problems.

[0006] This utility model is implemented as follows: a coal sample collection device for testing, comprising: a coal sample storage box; a stepper motor fixed to the center of the top of the coal sample storage box by bolts; a turntable fixed to the output end of the stepper motor; a coal receiving cavity opened on the top of the turntable; a feed inlet opened on the top of the coal sample storage box near the side of the stepper motor; a crushing box fixed to the top of the coal sample storage box near the outside of the feed inlet by bolts; a feeding hopper welded to the top of the crushing box; a reduction motor fixed to the outer wall of the crushing box by bolts; a crushing roller fixed to the output end of the reduction motor; a guide plate welded to the inner wall of the crushing box near the position above the crushing roller; an inclined plate welded to the inner wall of the crushing box near the position below the crushing roller; a diverter integrally formed on the top of the inclined plate; a discharge cover fixed to the outer wall of the crushing box near the side of the inclined plate by screws; a sealing cap screwed onto the bottom of the coal sample storage box near the position directly below the feed inlet by threads; and a base fixed to the bottom of the coal sample storage box by bolts.

[0007] Preferably, the coal receiving cavity passes through the turntable, and the coal receiving cavity, the feed inlet, and the sealing cover are all located on the same circle with the same circumference.

[0008] Preferably, there are six geared motors in total, and the six geared motors are arranged in pairs at equal intervals on one side of the outer wall of the crushing box, and the crushing roller and the crushing box are rotatably connected.

[0009] Preferably, the diversion platform is an isosceles triangular prism structure, and the diversion platform is located in the middle and slightly below the two crushing rollers.

[0010] Preferably, the sealing cap has a T-shaped cross-section, and the top of the sealing cap and the bottom of the coal sample storage box are on the same horizontal plane.

[0011] Preferably, a through groove is provided on one side of the outer wall of the crushing box near the position between the inclined plate and the discharge hood.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0013] By crushing coal samples in stages within the crushing chamber and then diverting the crushed coal samples using a diversion platform, a portion can be discarded, reducing the workload of subsequent crushing and improving the efficiency of sample collection and crushing. Multi-stage crushing increases the number of coal particles in the sample, improving sample preparation precision. The rotating turntable allows multiple coal collection chambers 4 on the turntable to temporarily store coal samples collected from different sampling points, facilitating subsequent merging into a single coal sample for subsequent coal testing.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a coal testing sample collection device, such as... Figure 1-4As shown, the system includes a coal sample storage box 1. A stepper motor 2 is bolted to the center of the top of the coal sample storage box 1. A turntable 3 is bolted to the output end of the stepper motor 2. A coal receiving cavity 4 is welded to the top of the turntable 3. The outer wall of the turntable 3 matches the inner wall of the coal sample storage box 1. A feed inlet 5 is provided on the top of the coal sample storage box 1 near the stepper motor 2. A crushing box 6 is bolted to the outer side of the top of the coal sample storage box 1 near the feed inlet 5. A feeding hopper 7 is welded to the top of the crushing box 6. A reduction motor 8 is bolted to the outer wall of one side of the crushing box 6. There are six reduction motors 8 in total, arranged in pairs at equal intervals on the outer wall of one side of the crushing box 6. A crushing roller 9 is bolted to the output end of each reduction motor 8. The crushing rollers 9 and crushing box 6 are rotatably connected. The crushing capacity of the six crushing rollers 9 increases from weak to strong from top to bottom, so as to achieve step-by-step crushing of coal samples and thus collect the required particle size. A guide plate 10 is welded on one side of the inner wall of the crushing box 6 near the upper part of the crushing rollers 9, and an inclined plate 11 is welded on one side of the inner wall of the crushing box 6 near the lower part of the crushing rollers 9. A diversion platform 12 is welded on one side of the top of the inclined plate 11. A discharge hood 13 is fixedly connected to one side of the outer wall of the crushing box 6 near the inclined plate 11 by screws. A sealing cover 14 is screwed on the bottom of the coal sample storage box 1 near the feed inlet 5. The sealing cover 14 has a T-shaped cross-section, and the top of the sealing cover 14 and the bottom of the coal sample storage box 1 are on the same horizontal plane. Two bases 15 are symmetrically fixed to the bottom of the coal sample storage box 1 by bolts.

[0022] It should be noted that since the particle size of the collected samples is much larger than that of the coal samples used for testing, they must be crushed to reduce the particle size. Therefore, after sampling, the samples need to be removed and crushed again, which is cumbersome and increases the workload. In this embodiment, the coal samples are crushed in stages in the crushing chamber 6, and the crushed coal samples are divided by the diversion table 12. Discarding a portion of the samples can reduce the workload of subsequent crushing and improve the collection and crushing efficiency. Multi-stage crushing increases the number of coal sample particles and improves the sample preparation precision. The rotating turntable 3 allows multiple coal collection chambers 4 on the turntable 3 to temporarily store coal samples collected from different sampling points, which is convenient for subsequent merging into a coal sample and thus realizes the subsequent coal test.

[0023] Specifically, in this embodiment, the solution mainly includes a turntable 3 and a crushing box 6. During use, due to the large sample size, if the sample needs to be crushed to the required particle size for analysis in one go, the sampled coal (one of raw ore, concentrate, tailings, or slag) is placed into the feeding hopper 7. Guided by the guide plate 10, the coal sample enters between two crushing rollers 9. The reduction motor 8 drives the crushing rollers 9 to rotate through its output end on one side. The two crushing rollers 9 rotate in opposite directions to crush the coal sample. After preliminary crushing, the coal sample moves downwards under gravity. Under the diversion of the diversion table 12, a portion of the preliminary crushed coal sample falls onto the inclined plate 11 and moves to the discharge hood 13 under the inclined guidance of the inclined plate 11, and is then discharged through the discharge hood 13. The other portion of the preliminary crushed coal sample falls between the next stage two crushing rollers 9. After the coal sample is crushed in opposite directions, it is crushed again. Similarly, the coal sample is crushed again and then moves downward in the crushing box 6 before undergoing final crushing. This achieves multi-stage crushing of the coal sample. After each stage of crushing, a portion is discarded, which can reduce the workload of subsequent crushing. Multi-stage crushing increases the number of coal particles and improves the sample preparation precision. The finally crushed coal sample falls into the coal collection chamber 4 on the turntable 3 after passing through the feed inlet 5. After each type of coal sample is collected, the stepper motor 2 is controlled to drive the turntable 3 to rotate at a certain angle through its output end on one side, so that the coal collection chamber 4 above the turntable 3 moves to directly below the feed inlet 5, thereby collecting and storing another type of coal sample. For sampling, the sealing cap 14 is unscrewed, and the turntable 3 is controlled to move the coal collection chamber 4 to directly above the sealing cap 14. The coal sample in the coal collection chamber 4 falls out, thus achieving sampling.

[0024] In a further preferred embodiment of this utility model, such as Figure 3-4 As shown, the coal receiving cavity 4 passes through the turntable 3, and the coal receiving cavity 4, the feed inlet 5, and the sealing cover 14 are all located on the same circle with the same circumference.

[0025] In this embodiment, by using the coal receiving cavity 4, the feed inlet 5 and the sealing cover 14, which are located on the same circumference and have the same center, the coal receiving cavity 4 can be made to coincide with the coal receiving cavity 4 and the feed inlet 5 in the vertical direction when the coal receiving cavity 4 moves axially, thereby realizing feeding and unloading.

[0026] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the diversion platform 12 is an isosceles triangular prism structure, and the diversion platform 12 is located in the middle and lower position between the two crushing rollers 9.

[0027] In this embodiment, the splitter 12 can divide the crushed coal sample into two parts, reducing the amount of subsequent crushing and improving crushing and collection efficiency.

[0028] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, a through groove is provided on one side of the outer wall of the crushing box 6 near the position between the inclined plate 11 and the discharge hood 13.

[0029] In this embodiment, the inclined plate 11 and the discharge hood 13 are connected by the through groove, so that the coal sample on the inclined plate 11 flows to the discharge hood 13 and is finally discharged through the discharge hood 13.
