Description

Technical Field

[0001] The present invention relates to the technical field of slag crushers, in particular to an intermittent tooth slag crusher, a slag block identification system and a crushing method. Background Art

[0002] In thermal power plants, slag crushers are mainly used to break up large pieces of slag in the boiler's slag discharge system so that it can be transported to subsequent processing equipment. Existing slag crushers are mostly double-row tooth plate continuous tooth type slag crushers and hammer slag crushers. However, double-row tooth plate continuous tooth type slag crushers have problems with uneven tooth plate wear and high energy consumption, while hammer slag crushers have high noise and rapid wear of the hammer head, which further increases maintenance costs and environmental burdens.

[0003] In addition, existing slag crushers usually adopt a fixed gap design and cannot dynamically adjust the crushing parameters according to the actual size of the slag blocks, resulting in low crushing efficiency and even jamming or equipment damage. In addition, there is a lack of intelligent monitoring and control methods, and the equipment needs to operate continuously at high power, which not only increases energy consumption but also aggravates equipment wear. It is also difficult to effectively separate fine slag from coarse slag, which complicates the subsequent processing process and reduces the overall processing efficiency.

[0004] Based on the above problems, we proposed an intermittent tooth slag crusher, a slag block identification system and a crushing method. Summary of the Invention

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0028] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0029] Reference Figures 1 to 3 This embodiment provides an intermittent tooth slag crusher, including an extrusion part 1 and a slag crushing part 2. The extrusion part 1 is mainly responsible for the crushing task of large slag materials to avoid blockage in the subsequent transportation link, and the slag crushing part 2; the extrusion part 1 includes a push plate 11, and the outer wall of the push plate 11 is provided with a jaw plate 12. The jaw plate 12 is preferably a grooved jaw plate, so that the hardest component in the crushing plate of the slag crusher can cope with the hard slag squeezed over and perform powerful crushing.

[0030] The slag crushing part 2 includes a rotating roller 21, and a flat plate 22 and a tooth plate 23 are provided on the outer wall of the rotating roller 21, and the flat plate 22 and the tooth plate 23 are arranged in a staggered manner; the flat plate 22 and the tooth plate 23 are fixed to the outer wall of the rotating roller 21 by bolts, and the tooth structure of the tooth plate 23 can effectively prevent the slag blocks from slipping or getting stuck during the crushing process, ensuring that the slag blocks are always in a stressed state; the staggered arrangement of the flat plate 22 and the tooth plate 23 can also prevent the slag blocks from accumulating on the surface of the rotating roller, reducing the risk of equipment blockage and ensuring the continuous operation of the equipment; the flat plate 22 can provide a large area of extrusion and grinding The rotating roller 21 has a plurality of combined tooth plates 23 on its outer wall. The teeth of each row of tooth plates 23 are of different sizes and can act alternately on the slag during the crushing process, thereby realizing multi-level and multi-form crushing. The design of different tooth sizes can make the tooth plates wear more evenly during use. The alternating work of large and small teeth shares the crushing load, thereby preventing the tooth plates of a single size from failing due to excessive local wear.

[0031] A crushing gap 13 is formed between the jaw plate 12 and the tooth plate 23. When the slag is too large, the crushing gap 13 can be reduced to increase the extrusion force, thereby achieving more thorough crushing. The width of the crushing gap 13 can be adjusted by pushing the push plate 11. Adjusting the crushing gap 13 can crush the slag. The movement of the push plate 11 realizes the dynamic adjustment of the crushing gap 13, so that the equipment can adapt to slag of different sizes and hardness.

[0032] As an optional embodiment, a connecting plate 14 is provided on the push plate 11 away from the jaw plate 12. The jaw plate 12 is fixedly arranged on the outer wall of the push plate 11. The position of the jaw plate 12 is adjusted according to the position of the push plate 11, so that the width of the crushing gap 13 can be adjusted. The connecting plate 14 can be fixed to the outer wall of the push plate 11 away from the jaw plate 12 by welding or other connection methods.

[0033] As an optional embodiment, each group of tooth plates 23 corresponds to two groups of extrusion parts 1; the extrusion part 1 also includes a mounting shell 15 provided on the outer wall of the slag crusher. The mounting shell 15 can be fixed on the outer wall of the slag crusher by welding or other connection methods, and the fixed shaft 16 running through the interior thereof provides a support point for the connecting plate 14.

[0034] As an optional embodiment, Figure 2As shown, the connecting plate 14 is rotatably connected to the outer wall of the fixed shaft 16, one end of the connecting plate 14 is connected to the push plate 11, and the other end is installed on the fixed shaft 16 by a rotatable connection, so that the connecting plate 14 can rotate with the fixed shaft 16 as a fulcrum; and because the connecting plate 14 can rotate around the fixed shaft 16, the displacement path of the push plate 11 can be more accurately controlled when adjusting the crushing gap 13, thereby avoiding inaccurate gap adjustment due to mechanical errors.

[0035] As an optional embodiment, Figure 3 As shown, the extrusion part 1 also includes a driving cylinder 17 arranged on the outer wall of the crusher. The driving cylinder 17 is preferably a hydraulic cylinder, but a variety of driving methods can still be adopted, which are not specifically limited here. The driving cylinder 17 is arranged on the outer wall of the crusher, with a clear position and easy disassembly, which is convenient for later maintenance and replacement; the output end of the driving cylinder 17 passes through the outer wall of the crusher and rests on the outer wall of the push plate 11. The driving cylinder 17 directly acts on the push plate 11, avoiding a complicated transmission mechanism, simplifying the equipment structure, and improving the operation stability.

[0036] As an optional embodiment, the slag crushing part 2 also includes a filter screen 24 provided on the side of the rotating roller 21 away from the extrusion part 1, and a fine slag channel 25 is provided below the filter screen 24, and the fine slag channel 25 is connected to the discharge port 27; when the slag blocks need to be processed, the transported slag blocks first pass through the filter screen 24 and are filtered by the filter screen 24, so that the slag blocks with smaller size and lower hardness can fall directly into the fine slag channel 25, and flow out directly from the discharge port 27 through the fine slag channel 25 and directly proceed to the next level of transportation; the slag blocks with smaller size and lower hardness are separated through the filter screen 24 before entering the slag crusher and do not need to be squeezed and crushed by the slag crusher, which reduces the wear of the slag crusher and avoids the slag blocks that have met the particle size requirements from occupying the working time of the slag crusher, while the coarse slag is intercepted above the filter screen 24 and continues to be pushed into the feed port 26 for crushing process, ensuring that the slag blocks that do not meet the standards will not enter the subsequent links, thereby improving the overall processing quality.

[0037] As an optional embodiment, a feed port 26 is provided on the side of the filter screen 24 away from the outer wall of the slag crusher. The feed port 26 is connected to the crushing gap 13 and the discharge port 27 in sequence. The slag blocks intercepted above by the filter screen 24 are squeezed and crushed by entering the feed port 26.

[0038] The slag that has not been filtered by the filter 24 is pushed into the feed port 26 and crushed by the rotation of the slag crushing part 2. At this time, the width of the crushing gap 13 does not need to be adjusted. When encountering slag blocks with larger hardness or larger size, the rotating flat plate 22 and the tooth plate 23 cannot crush them. Then, by starting the drive cylinder 17, the output end of the drive cylinder 17 pushes the push plate 11, causing the connecting plate 14 to rotate around the fixed axis 16, further causing the push plate 11 to drive the jaw plate 12 to rotate, thereby reducing the width of the crushing gap 13. The extrusion of the jaw plate 12 and the rotation of the tooth plate 23 are used to squeeze and crush the slag blocks with larger hardness or larger size, thereby avoiding blockage in the subsequent conveying process.

[0039] Reference Figure 4 This embodiment provides a slag block identification system, comprising an infrared monitoring module 3, a data processing module 4, and an execution module 5; these modules work in conjunction to achieve intelligent monitoring and efficient processing of coal slag. The infrared monitoring module 3 is preferably an infrared imaging camera, which can be installed on the outer wall of the slag crusher. It utilizes highly sensitive infrared sensing technology to capture the heat distribution on the coal slag surface in real time and generate a clear slag image based on the thermal characteristics of the slag block. The infrared imaging camera is the preferred option for the infrared monitoring module 3, but in different application scenarios, other alternative or supplementary methods can be selected based on demand, such as laser ranging sensors, ultrasonic sensors, visual recognition systems, mechanical detection devices, multispectral imaging technology, radiographic imaging technology, and pressure sensor arrays. The infrared monitoring module 3 can accurately collect coal slag size data and upload this data to the data processing module 4.

[0040] The data processing module 4, as the core processing unit of the system, receives the coal slag size data from the infrared monitoring module 3 and analyzes and judges the data through the built-in efficient data algorithm. The module will evaluate the size of the coal slag according to a preset threshold (such as the coal slag size range). If the coal slag size is larger than the set threshold, it will generate an instruction to adjust the width of the crushing gap; if the coal slag size meets the requirements, no adjustment is required. Subsequently, the data processing module 4 sends the decision instruction to the execution module 5; the execution module 5 is responsible for converting the received instruction into a specific mechanical action. When receiving the instruction to adjust the crushing gap, the execution module 5 will drive the drive cylinder 17 to push the push plate 11, thereby dynamically adjusting the width of the crushing gap between the jaw plate 12 and the tooth plate 23 to ensure that large pieces of coal slag are targeted and crushed.

[0041] Reference Figure 4This embodiment also provides a slag crushing method, including filtering fine slag into a fine slag channel through a filter screen for next-stage transportation, that is, after the slag first enters the system, the fine slag is separated out through the filter screen.

[0042] The fine residue is filtered into the fine residue channel and enters the next stage of transportation without further crushing;

[0043] Monitor the size of the remaining slag blocks through infrared and upload them to the data processing module 4;

[0044] The data processing module 4 analyzes the received slag block size data to determine whether the slag block is larger than a preset size threshold;

[0045] If the slag is larger than the set threshold, the next step is to adjust the width of the crushing gap;

[0046] Specifically, for slag blocks larger than a set threshold, the data processing module 4 generates an instruction to adjust the width of the crushing gap and sends it to the execution module 5; the execution module 5 drives the drive cylinder 17 to push the push plate 11 to adjust the width of the crushing gap between the jaw plate 12 and the tooth plate 23; after the adjustment is completed, the drive cylinder 17 pushes the push plate 11 to extrude and crush the slag blocks.

[0047] If the slag block is smaller than or equal to the set threshold, it will directly enter the slag crusher for conventional crushing.

[0048] As an optional embodiment, the system monitors the operating status of the slag crusher in real time to determine whether the crushing process is completed normally;

[0049] If the crushing is normal, the crushed slag will be transported to the next level of processing;

[0050] If the crushing is abnormal, the manual intervention mechanism will be triggered and the operator will check and solve the problem.

[0051] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
