[0023] Working principle:
[0024] The utility model provides a feeding device for liquid materials. A vacuum siphon tank is arranged between a liquid storage tank and a self-priming pump. The vacuum siphon tank is connected to the liquid storage tank through an infusion pipeline. A limiting mechanism on the infusion pipeline adopts a retractable limiting rod. When the infusion pipeline reaches the bottom of the liquid storage tank, the limiting rod touches the bottom, and the port of the infusion pipeline is erected so as not to contact the sediment at the bottom of the liquid storage tank. The floating mechanism on the infusion pipeline adopts a floating plate with a certain thickness, i.e., a floating plate. A through hole is arranged at the center of the floating plate for the up and down movement of the infusion pipeline. The floating plate floats along with the liquid surface until the liquid surface drops to the bottom. The floating objects on the surface of the liquid surface fall onto the sediment and are blocked by the limiting mechanism, so that the infusion pipeline never contacts the suspended matter and the sediment, and only the liquid materials in the suspended matter and the sediment are always sucked.
