Description

Technical Field

[0001] This utility model relates to the field of coal testing technology, and in particular to an online coal sample analysis and testing device. Background Technology

[0002] In industrial sectors involving coal utilization, such as coal processing, power generation, and chemical raw material preparation, online coal sample analysis and testing is a crucial link in ensuring production efficiency, product quality, and safety and environmental protection. By real-time monitoring of core indicators such as moisture, ash content, and calorific value, it provides precise data support for adjusting production processes and optimizing combustion efficiency. However, existing online coal sample analysis and testing devices still suffer from several technical challenges in practical applications. Insufficient precision of the sampling drive mechanism leads to large deviations in sample collection and insufficient representativeness. The lack of an effective material guiding structure in the conveying pipeline easily causes coal sample accumulation and blockage. Furthermore, coal samples are easily contaminated or lose moisture during transportation. Additionally, the sampling rod wears out quickly and requires frequent maintenance. The high cost, decentralized control of various functional modules, poor coordination, cumbersome operation, and limited data transmission methods make it difficult to adapt to the networking needs of different industrial scenarios. Some equipment lacks effective heat dissipation design, resulting in poor long-term operational stability. The lack of a reliable radiation shielding structure in the analysis chamber poses a potential threat to the safety of operators. Furthermore, components such as sampling hoses are mostly fixed connections, making disassembly and maintenance inconvenient. The overall installation flexibility of the device is insufficient, making it difficult to adapt to different coal flow heights and uneven sites. These defects seriously affect the reliability of detection data, production continuity, and the promotion and application of the device. There is an urgent need to develop a reasonably structured and reliable online coal sample analysis and detection device to solve the above problems. Utility Model Content

[0009] Preferably, the bottom of the transport pipe is provided with an inclined material guiding structure, which guides the coal sample to slide automatically into the transport pipe by the inclined angle, thus avoiding coal sample accumulation.

[0010] Preferably, the sampling drive component is a servo motor, whose output shaft is connected to the sampling rod for transmission. The transmission structure enables precise control of the sampling action, while improving the sampling rod's resistance to coal sample wear, extending the service life of the sampling component, and ensuring the representativeness of the coal sample collection.

This utility model uses a sampling drive component to drive the sampling rod to extend, retract, and rotate along the sampling rod sleeve, achieving accurate coal sample collection and ensuring the representativeness of the coal sample. At the same time, with the coordinated cooperation of the inclined material guiding structure at the bottom of the transport pipe and the coal sample conveying mechanism, the coal sample in the sample collection box is automatically gathered and smoothly pushed. After merging with the coal sample collected by the sampling rod, it is introduced into the analysis chamber along the appropriate pipeline.

The sealing structure of the sample inlet maintains a stable detection environment inside the chamber, preventing external air and dust from interfering with the state of the coal sample. This ensures that the detection process is not affected by environmental factors, significantly improving the accuracy and reliability of detection data for core indicators such as moisture, ash, and sulfur content of coal samples, and providing precise data support for production process adjustments.

[0025] Working principle: After the device is fixedly installed by the base 1 and fixing bolts 2, the control box 22, as the core control unit, receives operation commands and links various functional modules to start operation: the sampling drive component 10 is fixed on the fixed seat 12 at the top of the sampling connecting rod 11, the sampling rod sleeve 9 is connected to the sampling rod 8, and drives the sampling rod 8 to extend, retract and rotate along the sampling rod sleeve 9 to accurately collect coal samples. The collected coal samples are transported through the sampling hose 13 connected to the upper part of the sampling rod sleeve 9 to achieve smooth transmission of coal samples without residue, and finally introduced into the coal sample analysis chamber 16. After the coal sample enters the coal sample analysis chamber 16, the radiation shielding device 1603 on the inner wall of the chamber blocks the radiation risk during the detection process and ensures the safety of the operator. The stirring shaft 1602, which is movably connected to the fixed shaft 1601, is started. The stirring action ensures uniform distribution of the coal sample. The analysis chamber maintains a stable internal detection environment through the sealed inlet structure, preventing external interference. Subsequently, the internal detection unit is activated to perform online analysis of the core indicators of the coal sample. Operators can monitor the state of the coal sample in the chamber in real time through the analysis chamber observation window 18 on the analysis chamber door 17. After the detection is completed, the coal sample conveying mechanism 7 reverses its direction, transferring the analyzed coal sample back to the sample collection box 3, realizing a closed-loop coal sample flow. The control box 22 receives and processes the detection data in real time through its internal circuitry, and transmits it to external devices via the communication interface 21 or the rotatable and adjustable control box antenna 23 to complete data interaction. During operation, the heat dissipation component 20 automatically adjusts the heat dissipation efficiency according to the temperature of the internal circuitry of the control box, avoiding equipment failure due to high temperature and ensuring long-term stable operation of the device.
