Description

Technical Field

[0001] This application relates to the field of flap valve technology, and more specifically, to a combined flap valve device. Background Technology

[0002] Flap valves can be used for unloading and conveying various materials. However, when there is a need for crushing materials, additional crushing equipment needs to be installed, which not only increases the floor space but also prolongs the material production time. At the same time, when existing flap valves are used for a long time, the material tends to form a crust on the inner wall of the shell, which leads to poor material discharge. Manual cleaning is often required, which is time-consuming, labor-intensive, and labor-intensive. Therefore, a combined flap valve device that can unload and crush materials at the same time and effectively avoid the formation of crusts on the inner wall of the shell, thus preventing blockage, is proposed.
