The structure of the weightless scale and the function of each component

A complete weightlessness scale generally has: main parts such as feed gate, weighing hopper, agitator, discharge device, frame, weighing sensor and metering control device. Let's take a look at the specific functions of each item in detail below: weightlessness scale-feed gate The main function of the feed gate in the weightless scale is to feed the weighing hopper. The feed gate generally uses ball valves, butterfly valves, gate valves, etc. The main requirements of the feed gate are performance indicators such as airtightness, switch flexibility, fast feeding and smooth flow. Weightlessness Scale-Weighing Hopper The function of the weighing hopper in the weightlessness scale is the carrier of heavy materials. The material used for the weighing hopper is generally corrosion-resistant and acid-resistant. Its volume is selected according to the feeding volume of 3 minutes at the maximum feeding flow rate, and the feeding time should account for the largest proportion of the entire weighing process about 10%. Weightlessness scale-agitator The function of the agitator in a weightlessness scale is to assist in discharging materials with poor fluidity. The agitator is composed of a simple arch-breaker drive motor with spiral blades or spike teeth. Through the rotation of the broken arch arm, the materials prone to arching and rat holes can smoothly fall to the exit site. Weightlessness scale-discharging device The main function of the discharging device in the weightlessness scale is to discharge the bulk materials in the weighing hopper. Generally, screw feeders, impeller feeders, vibrating feeders, and belt feeders can be used. . The characteristics of the materials and the use environment are different. It can be used in most applications. The screw feeder is more superior than other closed discharge devices. It can transport materials evenly and prevent powdery materials from flying and spraying. Weightless Scale-Load Cell In a weightless scale, the load cell converts the weight signal of the material into an electrical signal for output. Generally, sturdy high-resolution strain gauge sensors are used. Therefore, the load cell is the core weighing component of the weightlessness scale. Weightlessness scale-measurement control device The measurement control device in the weightlessness scale is composed of an intelligent weighing instrument and an automatic control system. The main function is to control and measure the feeding rate, conveying volume, etc. In addition, the inlet and outlet of the weightlessness scale should generally adopt flexible dust-proof and air-tight soft connections to ensure that the connection between the storage bin and the subsequent equipment does not hinder the weighing. The weighing hopper of the weightlessness scale and the adjustable discharge device installed under it are all seated on the load cell fixed to the frame. The above is the structural composition of the weightlessness scale and the functions and requirements of the specific components brought to you by this editor. Hope it can help everyone.
