Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology, specifically to a crushing and weighing integrated device applied to a coal rapid detection system. Background Technology
[0002] Significant breakthroughs have been made in rapid coal testing technology, evolving from traditional radioactive element analysis to fusion spectroscopy and LIBS technologies. This has greatly improved the system's scalability and applicability. Rapid coal testing systems can complete the analysis of 6mm coal samples in just two minutes. Installing these systems on existing mechanical coal sampling machines in power plants saves space, reduces costs, and allows for real-time data comparison, making them the primary choice for most power plants. However, current coal sampling machines at power plants typically use crushers that break coal to a particle size of 13mm before collecting both full-moisture and analytical samples. Online rapid testing technology, on the other hand, requires continuous samples of 10-15kg coal with a particle size of 6mm to achieve accurate data.
[0003] Therefore, the solution that best suits the rapid testing system is to crush the 13mm coal sample to 6mm and temporarily store it to 10-15kg before putting it into the rapid testing system. The original sampling machine system was not designed with enough space to install this device, so the device must be compact, well-sealed, and reliable in operation. Utility Model Content

[0057] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0058] Please see Figures 1-4 This application provides the following technical solutions:
[0059] An integrated crushing and weighing device for a coal rapid testing system includes a crushing unit 1, a collection unit 2, and a collection control unit 3. The crushing unit 1 includes a crushing shell 11, with a crushing chamber inside. A feed pipe 12 is located at the top of the crushing shell 11, and a crushing discharge pipe 13 is located at the bottom. A crushing support structure 15, which is a ring-shaped frame, is located at the bottom of the crushing shell 11. A crushing assembly 14 is installed inside the crushing shell 11. The collection unit 2 is located below the crushing unit 1 and includes a collection shell 21. The collection shell 21 is located below the crushing unit 1 and has a collection bin 22 inside for receiving the crushed material. The upper and lower ports of the collection bin 22 are open, and the upper port of the collection bin 22 is connected to the crushing discharge pipe 13. The collection control unit 3 controls the release or collection of material inside the collection unit 2.
[0060] The material collection control unit 3 includes a material collection gate 31 and a control component 32. The material collection gate 31 is rotatably mounted on the lower side of the lower port of the collection bin 22; the control component 32 is linked to the material collection gate 31, and the control component 32 can control the material collection gate 31 to open or close.
[0061] This solution uses crushing unit 1 to crush the coal sample to be weighed, ensuring it meets the size requirement of the coal rapid testing system, which is 6mm particle size. The crushed coal sample is temporarily collected and stored in collection bin 22. When the stored coal sample reaches 10-15kg as required by the coal rapid testing system, the material collection control unit 3 opens the material collection gate 31, and the coal sample in collection bin 22 falls into the rapid testing feed pipe 100 in one go, where it is tested by the coal rapid testing system.
[0062] Based on the above implementation scheme, the crushing assembly 14 includes a crushing drive component 141 for use as a crushing power source. The crushing drive component 141 includes a crushing motor fixedly connected to the crushing housing 11. The motor shaft of the crushing motor is fixedly connected to the crushing main shaft 142, and the lower part of the crushing main shaft 142 extends into the interior of the crushing housing 11. Crushing components 143 are provided on the shaft of the crushing main shaft 142, and several crushing components 143 are distributed along the axial direction of the crushing main shaft 142.
[0063] The crushing component 143 can take many different forms. This solution adopts a structure that uses the rotation of the crushing main shaft 142 for crushing.
[0064] In addition, crushing structures such as combined crushing rollers and vibrating plate crushing structures can be used as adaptive replacements for the crushing component 14 in this solution.
[0065] Based on the above implementation plan, see Figure 2 In this design, the crushing discharge pipe 13 is an inverted frustum-shaped structure. A sliding plate 131 is installed inside the crushing discharge pipe 13, and the sliding plate 131 is made of ultra-high molecular weight polyethylene. This structure allows the discharge pipe 13 to have better material feeding efficiency.
[0066] Based on the above implementation plan, see Figure 2 The crushing component 143 includes a crushing frame, crushing connectors, and crushing blocks. The crushing frame is a circular frame fixedly connected around the crushing main shaft 142. The crushing connector is a chain, with one end rotatably connected to the crushing frame and the other end fixedly connected to a crushing block, which is a polygonal block. Several crushing connectors and crushing blocks are arranged in a one-to-one correspondence around the crushing frame.
[0067] Different structural forms can be used for the crushed blocks on the same crushing frame, such as rectangular blocks and trapezoidal blocks, etc.
[0068] With the structure of this scheme, as the crushing main shaft 142 rotates, the crushing connector swings the crushing blocks to crush the coal sample.
[0069] Based on the above implementation plan, see Figure 1 and Figure 4 The upper edge of the collection shell 21 is connected to the crushing discharge pipe 13; the crushing discharge pipe 13 extends into the interior of the collection shell 21. A collection connector 23 is provided between the crushing discharge pipe 13 and the collection chamber 22. The collection connector 23 is made of an elastic material, such as a rubber ring, a silicone ring, or other elastic material.
[0070] By setting the connecting piece 23, the collection bin 22 and the crushing discharge pipe 13 are flexibly connected, thereby ensuring the independence of the collection bin 22 and improving the accuracy of weighing the material in the collection bin 22 in the later stage.
[0071] Based on the above implementation scheme, the inside of the collection shell 21 is hollow, and the collection shell 21 mainly serves as a dustproof function. A collection support assembly 24 is provided on the outside of the collection bin 22 to support the collection bin 22. The collection support assembly 24 includes a collection bin frame, on which the collection bin 22 is placed. A weighing element, which is a weight sensor, is provided at the connection between the collection bin frame and the collection bin 22. The weighing element is electrically connected to the control component 32 of the collection control unit 3. When the weighing element senses that the material in the collection bin 22 meets the preset release weight, it feeds back to the control component 32, which then controls the collection gate 31 to open and release the material.
[0072] Based on the above implementation scheme, the opening and closing methods of the material collection gate 31 can be selected in multiple ways. This scheme provides the following form.
[0073] See Figure 1 , Figure 4 and Figure 5 The outer side of the collection gate 31 extends away from the collection bin 22, and the extended portion slopes upward. A tilting component is provided at the lower part of the structure extending from the collection gate 31 to... Figure 1 Taking the direction shown as an example, with the collection gate 31 closed, the tilting component moves towards... Figure 1 Extending to the lower right. The tilting component can be either a plate or a rod. The pivot connecting the collection gate 31 and the collection bin 22 is located between the tilting component and the collection gate 31.
[0074] The control component 32 includes a slide rail 321 and a slider 322. The slide rail 321 is vertically positioned outside the collection bin 22; the slider 322 is slidably connected to the slide rail 321. A slider drive component 323 is provided corresponding to the slider 321. The slider drive component 323 and the slider 322 are linked, driving the slider 322 to rise or fall. The slider drive component 323 uses a sprocket and chain combination, with the slider 322 fixedly mounted on the chain. A collection gate linkage component 324 is located at the lower part of the slider 322, extending to the underside of the tilting component. The collection gate linkage component 324 is a rod.
[0075] When the slider 322 rises, the material gate linkage 324 pushes the flipping component from bottom to top, thereby causing the material gate 31 to rotate downward and open.
[0076] Based on the above implementation scheme, the control component 32 also includes a positioning sensor 326. One positioning sensor 326 is respectively installed at the upper and lower ends of the slider 322's travel position to provide feedback on the travel position of the slider 322. The positioning sensor 326 can be selected from various forms such as a proximity sensor or a contact switch.
[0077] Based on the above implementation scheme, the control component 32 also includes a reset component 325, which is connected to the material collection gate 31 and can reset the material collection gate 31.
[0078] The reset element 325 can also take many different forms, as long as it can provide sufficient reset force to the collecting gate 31. For example, a counterweight can be set on the tilting element, so that the weight of the counterweight resets the collecting gate 31 after the slider 322 descends. Alternatively, a torsion spring can be set at the pivot of the collecting gate 31.
[0079] This solution uses a tension spring as the reset component 325. One end of the tension spring is connected to the collection gate 31 at a position away from the flipping component, and the other end of the tension spring is fixedly installed on the outside of the collection bin 22 or inside the collection shell 21.
[0080] Based on the above implementation scheme, the lower end of the material collection shell 21 is connected to the fast detection feed pipe 100 of the coal fast detection system, and a sealing element 25 is provided on the outside of the connection between the two. The specific form of the sealing element 25 is not limited, as long as it can make the connection a seal.
