Description

Technical Field

[0001] The utility model relates to a feeder, in particular to a cyclone feeder, belonging to the technical field of feeders. Background Art

[0002] Since the industrial production of powder coatings, improving the efficiency of grinders and reducing labor intensity have always been the goal pursued by manufacturers. Since the feeding system of the early grinders was located at a high position, it was extremely inconvenient, time-consuming and labor-intensive to transport materials to the hopper, so how to change the feeding system structure, reduce the height and improve efficiency has become the goal of manufacturers.

[0003] Through research, it was found that the suction force inside the grinding body of the grinder can be used to bring the material into the grinding body. In this way, wind suction feeding came into being. The patent with announcement number CN203648677U discloses a new type of high-efficiency cyclone feeding system, including a feeding hopper, the bottom of which is connected to a material conveying pipeline controlled by an external wind source, and the output of the conveying pipeline is connected to a cyclone separator installed on the top of the main mill. The cyclone separator separates the material and then settles it to the inside of the main mill through the main feeder below for grinding. Although a cyclone separator is used, due to the high position of the conveying pipeline, the cyclone formed is small and the separation effect is not good; at the same time, the feeding hopper is directly connected to the conveying pipeline, and the cyclone separator needs to be operated at high power to convey the material to the cyclone separator, which is slow and energy-intensive.
