The Buffer automatic batching machine is composed of components such as the material tank weighing module base, constant pressure tank system, and electric butterfly valve, combined with a control system with monitoring and feedback functions, and integrated with on-site feeding equipment to form an automatic Feeding machine assembly solution. It is mainly composed of a material tank equipped with a weighing module base, a constant pressure tank, an electric butterfly valve, a feeding pipeline and cementing equipment. The remaining powder ash in the material tank is used as the basis for judgment. When the remaining powder ash in the material tank is insufficient to complete a continuous and stable feeding process, the electric butterfly valve of the corresponding pipeline is closed, and the electric butterfly valve of the next material tank is opened to achieve automatic tank transfer and continuous and stable feeding operation.

The batching machine uses a liquid high-level sensor and a liquid low-level sensor to immediately detect the liquid height in the buffer tank. If the liquid in the buffer tank is lower than the center of the liquid low-level sensor, a 24V DC voltage will be output to open the normally closed solenoid valve. At this time, water will be injected into the buffer tank for the use of the mixer. When the water level in the buffer tank is higher than the center of the liquid level sensor, the 24V DC voltage output stops, and the normally closed solenoid valve is in the closed state. At this time, no more water is injected into the buffer tank. When the water level in the buffer tank is lower than the center of the liquid level sensor, water continues to be injected into the buffer tank, and this cycle repeats.

The batching machine achieves density priority by adjusting the opening degree of the water valve and the discharge flow of the large pump through the automatic flow distribution function. From the start of the operation to the premixed slurry process, ensure that density control is given priority and the stability of density control is maintained. Under the condition of stable liquid level, the control software smoothly controls the opening degree of the ash valve and water valve. To prevent significant fluctuations, an automatic displacement adjustment function is added. By setting a large pump displacement, the liquid level in the slurry mixing tank is kept stable. Multiple measures are linked to ensure the stability of density control. The operation process control design integrates various control processes of the low-pressure manifold into functional keys such as "Water inlet from the metering tank", "Water supply pump to the metering tank", "Filling from the slurry mixing tank", "filling from the metering tank", etc., facilitating the control switching of each process during operation.
