The jacketed weighing and mixing equipment is composed of an upper computer - industrial computer, a lower computer -PLC programmable controller, powder batching, liquid batching, micro-feeding and control system, etc. This control system is an automatic Weighing system that uses vacuum feeding, quantitative feeding by the feeding screw, automatic weighing and batching by the weighing hopper, and simultaneous cumulative weighing. It is suitable for precise measurement of materials and automatic batching operations in the production process.

The structure of the weighing mixer consists of a high-level silo, valves, vibrating motors, Weighing modules, reaction vessels, and a set of position detection devices. During the feeding waiting stage, the mobile bucket stops at the Electronic scale and the feeding port of the reaction tank, waiting for the control command. According to the feeding parameters input by the operator, the silo valve opens to discharge materials. The feeding amount is continuously collected through the weighing module. When the feeding set value - the lead amount is reached, the valve is closed. The lead amount can be calculated from the time of the valve or obtained based on experience. The valve will automatically close when the added materials reach the specified weight.

The composition of the automatic feeding system

The batching machine mainly completes the batching and mixing of powder and various liquid materials. The metering tanks are set up separately, and the liquid raw materials are metered and fed separately. Each raw material tank is equipped with a feeding pipeline at the bottom, which is controlled and switched by automatic valves and manual valves respectively. The automatic valve for each liquid material is installed near the pipeline outlet, and the feeding pump is responsible for sending the material through the pipeline to the metering tank. Return pipes and return valves are reserved at both ends of the feeding pump. An automatic valve is installed at the feeding port of the metering tank to achieve fast and slow feeding control of materials. Liquid or powder materials can be directly added to the metering tank through pipelines. Weighing modules are installed between the four support feet of the metering tank and the foundation of the support frame, which are responsible for measuring the weight of the materials entering the metering tank.

2. Through the automatic diversion device at the bottom of the metering tank, the materials are automatically added to the corresponding stirring tanks respectively. After the main discharge valve of the metering tank, the water body is horizontally installed to the automatic distribution valves of each stirring tank. The front feeding pipes of each automatic distribution valve are connected by pipelines. This can ensure that there is no material remaining after discharge. The discharge pipelines for powder and liquid materials to each agitator tank can be combined into one pipeline to reduce the cost of pipeline materials. The well-mixed finished products are pumped to the finished product tank through the pipeline at the bottom of the reaction vessel and are controlled by automatic valves and pumps.

3. All ingredient data are stored in the industrial control computer database in the control center. The ingredient process is monitored by configuration software and process operations are carried out through the control interface. Production data is stored in the system database in a timely manner to complete the storage and analysis of various production data. It can also realize various functions such as raw material storage and usage management, finished product management, personnel management, and contract management.
