Port Terminal Material Handling Weight Measurement (Checkout) System When bulk cargoes are transported from a cargo ship to a port terminal, it is often based on the weight obtained by the shipper based on the volumetric measurement (measured number of squares), and it is often difficult for the buyer to check the weight. Some people have tried the scales, but a lot of labor and time make it impossible for the buyer and the owner to tolerate it for a long time. Design a solution to this problem. The main content of the program: The material conveyed from the belt conveyor carried by the cargo ship first passes through a measuring belt conveyor with a length of about 2 meters and is then fed to the purchaser's material yard. The schematic diagram of the scheme is as follows: The system consists of the following parts è®¡é‡ Measuring belt conveyor. Conveyor belt, motor, reducer, load cell 秤 Weighing instruments. Sensor junction box. â—‡ Optional (not required to purchase): Computer records the host. (Recording statistics: date, ship number, owner, weight) Main Specifications â—‡ Measurement control accuracy: The error is better than 0.5% (depending on site and material conditions) â—‡ Work mode: continuous automatic, no increase in discharge time â—‡ Working voltage: 380VAC±10% 50Hz ±2Hz about 1.5Kw â—‡Environmental temperature: -10°C～45°C â—‡Interface signal: 0～10V or 4～20mA Metering belt conveyor â—‡ Highly reliable frequency control technology. The speed of the belt can be adjusted according to the incoming flow of the ship, which not only maintains the accuracy of the measurement, but also the accuracy of the measurement. Wide belt, thick material layer, low speed operation, so it has smooth running, nearly static measurement accuracy. The dynamic measurement accuracy is better than 1.0%; the static measurement accuracy is better than 0.5%, and the precision type is 0.125%. â—‡ Automatic quantitative adjustment with high precision and wide adjustment range (speed ratio ≥20:1, belt speed 5cm/min~15m/min). It also has good linear speed control performance at low speed, which can greatly reduce the wear of the belt and avoid the damage of the bulk materials. 性能 Good performance to price ratio. The use of the latest international technology, combined with many years of practice continue to improve and improve. Realized automatic belt centering, automatic tension adjustment, profile cleaner, roller bearing dustproof design, etc. High control accuracy, good stability, the price is only 1/4~1/5 of imported similar products. â—‡ Low operating and maintenance costs. In normal operation, the life of the endless belt can be as long as 5 years and save 20 to 40% of electricity; special quick and easy belt replacement means that only two people can quickly replace the belt. â—‡ According to the company's technological requirements "tailored", carry out on-site design to ensure reasonable selection and reliable operation. Flexible configuration, according to the process requirements of different types of equipment, such as cement line, the selection of high-temperature belt weigher; powder material sealed belt weigher. 皮带 The belt width is 500/650/800/1000/1200mm/1400/1800, which is suitable for the material flow range from 1 to 500t/h. Standard signals with 4 to 20mA or 0 to 10V can be interfaced with industrial computers or DCS systems. Weighing meter æ•°ç Digital display, small size, strong function â—‡ With weight display, flow display, parameter display å« With clear, parameter adjustment and other setting operations â—‡ Can be connected to the computer record host. Communication distance up to 1200 meters Computer Recorder (optional) â—‡ It consists of computer hardware and metering software. â—‡ Database structure. Record date, ship number, owner, weight, price and other data. 方便 Convenient statistics query. According to the statistics, the statistics can be queried on a monthly basis, on a daily basis, and on a shipper basis. â—‡ Print receipts can be printed instantly, and statistical reports printed.
