Description

Technical Field

[0001] The present invention relates to the technical field of solid waste detection, and particularly to a portable detection device for identifying the risks of bulk mineral solid waste. Background Art

[0002] Detection devices for the risks of mineral solid waste are used to evaluate the biological toxicity in solid waste. For example, toxicity tests are carried out using bacteria, aquatic organisms, etc. These tests can help determine the impact of solid waste on the ecosystem, thereby guiding the treatment and disposal plans of solid waste.

[0003] After retrieval, a Chinese patent with the publication number CN111453262A discloses a solid waste detector, which is applied in the technical field of detection devices. The key points of its technical solution are as follows: a detection cylinder with a cover plate is provided on the main body of the solid waste detector. Four ends of the bottom side of the main body of the solid waste detector are all connected with pulleys in a rolling manner. A sleeve is provided between the pulley and the main body of the solid waste detector. A damping spring is fixedly arranged on the inner wall of the sleeve along the width direction, and the other end of the damping spring is fixedly connected with the bottom side of the main body of the solid waste detector. A centrifugal mechanism for centrifuging solid waste is provided on the main body of the solid waste detector. The technical effects of the above solution are as follows: the solid waste falls into the detection cylinder under the action of gravity, and the operator covers the cover plate. The steam pipe further dries the solid waste, making the detection result of the detection cylinder more accurate. However, when the above solution is actually used, there are still the following deficiencies:

[0004] The existing solid waste detection devices usually only have the function of detection and do not have the functions of sample grinding and sieving. Their functionality is relatively single. Before solid waste detection, additional steps and equipment are required for sample processing, which will increase the time and cost required for the entire detection process. Each processing requires manpower and resources. For large-scale solid waste detection projects or continuous detection work, the increase in time and cost may significantly affect efficiency and economy. In addition, there are risks of sample loss and contamination every time the sample is transferred. For example, part of the sample may remain in the equipment and cannot be recovered during the sample grinding process, or it may be contaminated by the external environment during the transfer process, resulting in inaccuracy or deviation of the detection result. Secondly, data errors may be introduced during the sample processing process. For example, the particle size of the sample is uneven or some components are lost during the sample grinding process, or the sample is contaminated or cross-infected during the transfer process. These errors may affect the final detection result and data analysis.

[0005] Therefore, it is necessary to design a portable detection device for identifying the risks of bulk mineral solid waste to solve the above problems. Summary of the Invention

In addition, integrating the functions of grinding and sieving into the detection equipment can reduce the steps of manual sample processing, reduce the operation errors and risks that may occur during the sample processing process, which helps to improve the safety and reliability of the operation.

[0055] 2. The sieving box in the equipment generates a better sieving effect through vibration, which can effectively separate the powder part in the solid waste sample from the larger particles. This helps to improve the accuracy and efficiency of sample processing. In addition, the equipment utilizes the air supply component and the execution component to achieve the linkage effect of vibrating sieving, eliminating the need for an additional power source, saving energy consumption. At the same time, the automated process also reduces the misoperation that may be caused by manual operation, lowering the risk and potential safety hazards of equipment operation.

[0056] 3. After the grinding is completed, the box body can quickly collect the remaining samples, avoiding waste and loss of samples. This helps to improve the utilization rate of samples and resource conservation. The staff only needs to turn off the drive motor and rotate the lead screw and the threaded rod to move the bottom plate and the rotating grinding part, and collect and clean the residual samples. This simple operation process reduces the operation difficulty and improves the operation efficiency. In addition, this design enables the staff to easily clean the outer surface of the rotating grinding part and the inner surface of the fixed grinding part, effectively removing the residual powder. This helps to avoid cross-contamination between different samples and ensures the accuracy and reliability of subsequent sample detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0067] Refer to Figure 1-8 , a portable detection device for identifying the risks of bulk mineral solid waste, including a detection box 1, the detection box 1 includes a box body and a box cover, and the box cover is rotatably installed on the box body; a solid waste detection device 2, the solid waste detection device 2 is installed inside the detection box 1; a frame 4, the frame 4 is fixed inside the detection box 1; a grinding structure, the grinding structure includes a fixed grinding part 5 and a rotating grinding part 6. Among them, the fixed grinding part 5 is fixed on the frame 4, the fixed grinding part 5 is in a cylindrical structure, and both the upper and lower ends are provided with openings, and the lower opening of the fixed grinding part 5 is smaller than the upper opening. The rotating grinding part 6 is in a frustum shape, the cross-sectional diameter of the lower end of the rotating grinding part 6 is smaller than that of the upper end, and the rotating grinding part 6 extends into the fixed grinding part 5. There is a gap between the fixed grinding part 5 and the rotating grinding part 6, and the gap gradually decreases from top to bottom. Therefore, during the rotation of the rotating grinding part 6, the fixed grinding part 5 and the rotating grinding part 6 can continuously grind the sample. When the size of the sample becomes smaller, the sample will slide down. When the powder particles generated by grinding reach the lowermost ends of the fixed grinding part 5 and the rotating grinding part 6, the powder particles can meet the requirements for sample grinding.

When the driving motor 75 operates, it can drive the rotating grinding part 6 to rotate. Under the limiting action of the guide rod 73, when the threaded rod 71 rotates, it can drive the lifting seat 72 to move upward. When the lifting seat 72 moves, it can drive the driving motor 75 to move, which makes the rotating grinding part 6 move upward.

[0069] The device further includes a sieving structure. The sieving structure is arranged on the frame 4 and is located below the grinding structure. The sieving structure includes: a bottom plate 81; a mounting plate 82, which is fixed on the top surface of the bottom plate 81; a collecting box 83, which is slidably arranged on the mounting plate 82 through a sliding structure. The sliding structure includes: a chute 851, which is opened on the top surface of the mounting plate 82; a sliding rod 852, which is fixed inside the chute 851; a slider 853, which is slidably sleeved on the sliding rod 852, the top of the slider 853 extends outside the chute 851 and is connected to the collecting box 83, and the sieving box 84 is connected to the slider 853 through a detachable structure; a first spring 854, one end of the first spring 854 is connected to the groove wall of the chute 851, and the other end is connected to the slider 853; a sieving box 84, which is arranged on the collecting box 83 and is vertically aligned with the collecting box 83. A sieve is arranged inside the sieving box 84, and the sieving box 84 is located directly below the fixed grinding part 5.

[0070] The device further includes a vibration structure, which includes a gas supply component and an execution component. The gas supply component is driven by a driving structure to operate. The execution component is connected to the sieving structure. The gas supply component includes: an eccentric wheel 91, which is fixedly sleeved on the output shaft of the driving motor 75; a first sealing cylinder 92, which is fixed on the fixed grinding part 5; a first sliding plug 93, which is hermetically and slidably connected to the inner surface of the first sealing cylinder 92; a second spring 94, one end of which is connected to the inner surface of the first sealing cylinder 92 and the other end is connected to the first sliding plug 93; a first connecting rod 95, one end of which is fixed on the first sliding plug 93 and the other end extends to the outside of the first sealing cylinder 92; a control block 96, which is fixed on the end of the first connecting rod 95 located outside the first sealing cylinder 92. An inclined surface is provided on the control block 96, and the control block 96 is disposed opposite to the eccentric wheel 91; a communication pipe 97, one end of which is communicated with the first sealing cylinder 92. The execution component includes: a second sealing cylinder 101, which is fixed on the bottom plate 81 and is communicated with the other end of the communication pipe 97; a second sliding plug 102, which is hermetically and slidably connected to the inner surface of the second sealing cylinder 101; a third spring 103, one end of which is connected to the inner surface of the second sealing cylinder 101 and the other end is connected to the second sliding plug 102; a second connecting rod 104, one end of which is connected to the second sliding plug 102 and the other end extends to the outside of the second sealing cylinder 101; a through hole 105, which is opened on the mounting plate 82 and is communicated with the sliding groove 851. The second connecting rod 104 passes through the through hole 105 and is fixedly connected to the slider 853. During the rotation of the eccentric wheel 91, the first sliding plug 93 can continuously move up and down inside the first sealing cylinder 101. When the first sliding plug 93 moves down, the first sliding plug 93 can press the gas in the first sealing cylinder 101 into the second sealing cylinder 101 through the communication pipe 97. After the gas enters the second sealing cylinder 101, it can push the second sliding plug 102 to move, and the connecting rod 104 will also move accordingly. When the first sliding plug 93 moves up, the first sliding plug 93 can extract the gas in the second sealing cylinder 101. At this time, the second sliding plug 102 can reset under the action of the third spring 103, and the connecting rod 104 will also reset accordingly. Therefore, with the operation of the driving motor 75, the second connecting rod 104 can continuously reciprocate. When the second connecting rod 104 moves, it can drive the slider 853 to move, so that the collection box 83 and the sieving box 84 produce a vibration effect. The vibrating sieving box 84 can improve the sieving effect on the powder.

[0071] A detachable box body 11 is arranged on a bottom plate 81. The bottom plate 81 is connected to a detection box 1 through an adjustment structure. The adjustment structure includes: a fixed frame 121, which is fixed on the inner surface of the detection box 1 and has a U-shaped structure; a lead screw 122, which is rotatably installed on the fixed frame 121, and a hand wheel is installed at one end of the lead screw 122; a moving seat 123, which is threadedly sleeved on the lead screw 122 and is fixedly connected to the bottom plate 81, and the bottom surface of the moving seat 123 is in contact with the fixed frame 121. When the lead screw 122 rotates, it can drive the driving seat 123 to move, which causes the bottom plate 81 to also move. When the bottom plate 81 moves, it can drive the box body 11 to move until the box body 11 moves directly below the fixed grinding part 5, facilitating the direct fall of the residual sample into the interior of the box body 11.

[0072] The specific working principle of the present invention is as follows:

[0073] The detection equipment for identifying the risks of bulk mineral solid wastes proposed by the present invention not only has the function of detecting solid wastes, but also has the functions of sample grinding and sieving. Before detecting the solid wastes, the staff first grind the samples using the grinding structure, then sieve the sample powders using the sieving structure, and finally detect the sieved samples. The solid waste detection equipment 2 uses portable single-wavelength X-ray fluorescence and fundamental parameter method software, adopts the X-ray fluorescence spectrum diagram of the sample, and uses the fundamental parameter method to perform full-element quantification on the sample to summarize the composition range of normal imported minerals. The full-spectrum mineral fitting software is used to compare and score the samples from two dimensions: the spectral shape and the elemental composition. The full-spectrum mineral fitting software is set in the control computer 3, and there are many spectral diagrams of normal iron ores in the spectral library of the software. The samples are compared with these spectral diagrams respectively to obtain scores. Generally, there are two comparison methods. One is to average the comparison scores with the spectral diagrams of normal iron ores. When the score is less than a certain value, it is abnormal. When there is an abnormality, the spectral diagrams of all minerals including solid wastes in the spectral library can be compared. The sample closest to a certain sample can be identified as a certain other mineral or solid waste. The other is through the data accumulated in daily detections. The content ranges of the main components and main impurities of normal iron ores are stored in the software. By setting a threshold, once the detection result exceeds the threshold range, it indicates that the mineral composition is abnormal. This detection method is accurate. The fundamental parameter method software is used to establish an accurate calibration-free quantitative result. In addition, by comparing from two dimensions: the spectral library and the elements, the recognition probability is enhanced. Moreover, adding a large number of detections of rare trace elements to the recognition is also a unique advantage and innovative part of the present invention.

[0074] When grinding the sample, the staff first put the sample between the fixed grinding part 5 and the rotating grinding part 6, and start the driving motor 75. When the driving motor 75 runs, it can drive the rotating grinding part 6 to rotate. There is a gap between the fixed grinding part 5 and the rotating grinding part 6, and the gap gradually decreases from top to bottom. Therefore, during the rotation of the rotating grinding part 6, the fixed grinding part 5 and the rotating grinding part 6 can continuously grind the sample. When the size of the sample becomes smaller, the sample will slide down. When the powder particles generated by grinding reach the lowest end of the fixed grinding part 5 and the rotating grinding part 6, the powder particles can meet the requirements for sample grinding. Further, the powder generated during the grinding process will directly fall into the sieving box 84. A sieve mesh is arranged inside the sieving box 84, and the sieve mesh can screen the powder. The sieved powder will fall into the collection box 83. After the grinding and sieving work is completed, the staff can directly detect the powder in the collection box 83.

[0075] Further, when the driving motor 75 runs, it can also drive the eccentric wheel 91 to rotate. When the eccentric wheel 91 rotates, it can continuously squeeze the control block 96. When the eccentric wheel 91 squeezes the inclined surface of the control block 96, the control block 96 can move downward, which causes the first connecting rod 95 and the first sliding plug 93 to move downward and squeeze the second spring 94. When the eccentric wheel 91 and the control block 96 are separated from each other, the first sliding plug 93 will reset under the action of the second spring 94. Based on the above process, during the rotation of the eccentric wheel 91, the first sliding plug 93 can continuously move up and down inside the first sealing cylinder 101. When the first sliding plug 93 moves downward, the first sliding plug 93 can press the gas in the first sealing cylinder 101 into the second sealing cylinder 101 through the connecting pipe 97. After the gas enters the second sealing cylinder 101, it can push the second sliding plug 102 to move, and the connecting rod 104 will also move accordingly; when the first sliding plug 93 moves upward, the first sliding plug 93 can draw out the gas in the second sealing cylinder 101. At this time, the second sliding plug 102 can reset under the action of the third spring 103, and the connecting rod 104 will also reset. Therefore, with the operation of the driving motor 75, the second connecting rod 104 can continuously reciprocate. When the second connecting rod 104 moves, it can drive the slider 853 to move, causing the collection box 83 and the sieving box 84 to vibrate. The vibrating sieving box 84 can improve the sieving effect on the powder, enabling the powder to be sieved quickly. In addition, during the movement of the slider 853, the slide rod 852 plays a role in limiting the movement of the slider 853, and the first spring 854 arranged in the chute 851 is beneficial for the slider 853 to vibrate.

[0076] A box body 11 is also arranged on the bottom plate 81, which is used for quickly collecting the remaining samples after grinding. Specifically, after grinding, the staff turns off the driving motor 75 and rotates the lead screw 122. Since the side surface of the moving seat 123 is in contact with the fixed frame 121, the moving seat 123 cannot rotate along with the lead screw 122. Therefore, when the lead screw 122 rotates, it can drive the driving seat 123 to move, which causes the bottom plate 81 to move as well. When the bottom plate 81 moves, it can drive the box body 11 to move until the box body 11 moves to directly below the fixed grinding part 5. Then, the staff turns the handle on the threaded rod 71, causing the threaded rod 71 to rotate. Under the limiting action of the guide rod 73, when the threaded rod 71 rotates, it can drive the lifting seat 72 to move upward. When the lifting seat 72 moves, it can drive the driving motor 75 to move, which causes the rotating grinding part 6 to move upward until the rotating grinding part 6 moves out of the fixed grinding part 5. In this case, the samples remaining between the fixed grinding part 5 and the rotating grinding part 6 will fall into the box body 11, thus playing a role in quickly collecting the remaining samples.

[0077] In addition, when the rotating grinding part 6 moves out of the fixed grinding part 5, the rotating grinding part 6 no longer occupies the space inside the fixed grinding part 5, which facilitates the staff to use a brush to wipe the outer surface of the rotating grinding part 6 and the inner surface of the fixed grinding part 5, so as to clean the residual powder adhering to the outer surface of the rotating grinding part 6 and the inner surface of the fixed grinding part 5. Cleaning the residual powder is very important, which can avoid cross-contamination when detecting different types of solid waste and ensure the detection accuracy of the device for solid waste.

[0078] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
