Description
TECHNICAL FIELD
[0001] The utility model relates to material conveying technical field especially relates to a conveying material process monitoring device. BACKGROUND
[0002] In industrial production, the conveying of materials is a key link. Whether it is chemical industry, pharmaceutical industry, food processing or other manufacturing industries, materials usually need to be conveyed for a long or short distance through pipelines, conveyors and other means. However, during the conveying process, the flow rate, temperature and shape of the materials and other parameters have a crucial influence on product quality, production efficiency and equipment safety. Traditional material conveying processes often lack effective monitoring means or only simple monitoring of a single parameter. For example, for flow rate monitoring, some old-fashioned equipment can only make rough estimates and cannot accurately measure the flow rate. When the flow rate fluctuates abnormally, it cannot be discovered and adjusted in time, which may lead to insufficient supply of materials on the production line or blockage of the pipeline. In terms of temperature monitoring, inaccurate temperature detection may cause the materials to be conveyed at an unsuitable temperature, affecting the physical and chemical properties of the materials and thus affecting product quality. The monitoring of the shape of the materials is even more easily overlooked. Some special processes require the materials to have a specific shape or size, and if the shape deviates, it may cause the subsequent processing procedures to be unable to proceed normally. Moreover, the existing monitoring devices lack systematic integration, and the various monitoring data cannot be effectively associated and comprehensively analyzed, making it difficult to fully and accurately grasp the actual situation of the material conveying process and to make early warnings and responses to abnormal situations in time, thereby bringing many potential risks and losses to production. In addition, the humidity and composition of the materials also play a key role in product quality. Improper humidity may cause the materials to clump and deteriorate, and improper composition may cause the final product to fail to meet the expected performance standards, but most traditional monitoring devices do not effectively monitor these two important parameters. SUMMARY
[0003] The utility model aims at providing a conveying material process monitoring device, which can comprehensively and accurately monitor the flow rate, temperature, shape, humidity and composition of the materials during the conveying process and make timely early warnings of abnormal situations, effectively improving the safety, stability and production efficiency of material conveying.
[0004] The conveying material process monitoring device of the utility model mainly consists of the following parts:
[0005] Material flow monitoring unit: Its core component flow sensor is used to sense the flow of materials in the conveying pipeline or conveying belt in real time. Electromagnetic flow sensor or ultrasonic flow sensor can accurately measure the flow of materials according to the principle of electromagnetic induction or ultrasonic propagation characteristics. The signal collected by the flow sensor is amplified, filtered and processed by the signal conditioning circuit, and the original weak signal is converted into a standard signal suitable for data processing center receiving and processing.
[0006] Material temperature monitoring unit: The temperature probe is inserted into the material flow or close to the material conveying path. The thermocouple probe or thermal resistance probe uses the thermoelectric effect or the characteristic of resistance changing with temperature to accurately measure the temperature of the material. The temperature signal obtained by the temperature probe is converted by the temperature signal conversion circuit, and the physical quantity of temperature is converted into an electrical signal and transmitted to the data processing center.
[0007] Material shape monitoring unit: Image acquisition device is installed at specific key positions of conveying path, usually using high-definition camera, which can clearly capture image information of materials. Image analysis module uses image recognition software based on deep learning algorithm to analyze and process the collected images, extract shape features of materials such as length, width, contour, etc., and compare with preset standard shape parameters.
[0008] Material humidity monitoring unit: Humidity sensor is placed in the area where material flows through or contacts with material. Capacitive humidity sensor or resistive humidity sensor measures the humidity value of material accurately according to the principle that humidity change causes capacitance or resistance change. The humidity signal obtained by measurement is processed by humidity signal processing circuit, which is converted into a signal that can be recognized and received by data processing center, so as to analyze and judge the humidity data subsequently, and ensure that the humidity of material is in the appropriate process range.
[0009] Material composition monitoring unit: According to the characteristics of materials and production requirements, appropriate spectrum analysis technology or chemical sensor technology is adopted. Composition detection probe collects composition information of materials, such as infrared spectrum probe which can detect characteristic absorption peaks of specific chemical bonds or functional groups in materials to determine the chemical composition of materials; or mass spectrum probe is used to analyze molecular ion information of materials to determine their composition and content. The collected composition data is processed and converted by composition analysis circuit and transmitted to data processing center, which is compared and analyzed with preset standard composition parameters to ensure that the composition of materials meets the production process requirements.
[0010] Data Processing Center: As the core computing and control unit of the entire monitoring device, it can be an industrial control computer or a programmable logic controller (PLC). It receives data from the material flow monitoring unit, material temperature monitoring unit, material shape monitoring unit, material humidity monitoring unit, and material composition monitoring unit, and performs comprehensive analysis and processing of this data. For example, it determines whether the flow rate is within the normal production process range, whether the temperature meets the material's characteristic requirements, whether the material shape meets the standards for subsequent processing steps, whether humidity will affect material quality and processing performance, and whether the composition conforms to the product formula, etc.
[0011] Display unit: A liquid crystal display (LCD) or organic light-emitting diode display (OLED) is connected to the data processing center to display information such as material flow rate, temperature, shape, humidity and composition in an intuitive digital, chart or image format, so that operators can view various parameters of the material conveying process in real time.
[0012] Alarm Unit: When the data processing center determines that the material flow rate, temperature, shape, humidity, or composition exceeds a preset threshold, the alarm unit immediately issues an alarm signal. The alarm unit includes a loud audible alarm from a buzzer and flashing alarm indicator lights of different colors or frequencies, so that operators can promptly detect abnormalities and take appropriate measures, such as adjusting the material conveying speed, checking the heating or cooling system, checking the source of the material or previous processing steps, adjusting the material drying or humidifying equipment, and checking the material batching process.
