Hydraulic explosion-proof Electronic scales are used in various processes of production, processing, transportation, and storage. In many industrial sectors such as petroleum, chemical, and coal defense, various flammable and explosive gases, liquids, dust, and fibers may often leak or overflow. After mixing with air, these substances may become explosive mixtures. When the concentration of the mixture reaches the explosive concentration range, the appearance of a fire source can cause serious accidents such as explosions and fires. Electrical equipment used in such hazardous environments must be certified by institutions with explosion-proof electronic scales. Explosion proof electronic scale combines a series of data such as raw material storage management, production equipment control, production process monitoring, (semi-finished) product inventory management, production data tracking system, etc. by Internet information technology, and integrates and packs them to the Internet. After various raw materials are placed on their respective scales in the feeding equipment, they are fed into the scales according to the given ratio of the formula, weighed, and then sent to the hopper for a certain period of time to mix evenly into finished products. Various fixed formulas are inputted into the computer in advance, and the computer controls the feeding, weighing, and mixing according to the proportions of the formulas. The signals from the weighing module are detected in real time to make judgments and issue commands to the various executing mechanisms of the ingredients, thereby achieving ingredient automation. The entire production system is equipped with manual control auxiliary mechanisms, which can control operation in automatic or manual mode.

The weighing scale adopts a scale base, a scale body, a weighing sensor, a junction box, and a weighing instrument. The scale body is welded into a frame platform structure by surrounding support beams and panels. The four weighing sensors installed on the scale body are connected to the scale base through connectors. The panel of the scale body has a panel window opening, and the sealing plate is installed on the panel and covered by fasteners. The junction box is installed in the support beam offset on one side of the panel window. The inner side of the support beam is provided with a gap for placing the junction box, and the outer side is provided with cable holes. The movable side plate is installed on the support beam and covered by the gap; There are four groove shaped plates fixed on the outer side of the support beam of the scale body, which are located around the outer circumference of the weighing sensor. Horizontal limit columns are installed on the four corners of the scale base. The weighing sensor is connected to the input end of the junction box through a cable, and the shielded signal cable connected to the output end of the junction box passes through the cable hole on the support beam and is connected to the weighing instrument. The support beams of the electronic weighing scale are made of channel steel or rectangular tubes, and adjacent pairs of support beams are fixed as a whole through connecting plates. The inner side of the support beams is equipped with reinforced beams, and installation plates are installed at the four corners of the panel. The weighing sensor is installed on the installation plate through fasteners, and the four corners of the scale base are fixed with supports. The connecting pieces are installed on the weighing sensor and the support.
