Patent number: 11590440Abstract: A method produces a porous, arched aluminum fluidization element for a diaphragm pump for fluidizing, covering and delivering pulverized products, such as pulverized coal, using inert gas at pressures of up to 7 MPa. The fluidization element ensures that fluidizing gas is supplied and homogeneously distributed in the pump lower region, and the contour of the space for pulverized materials may be advantageously designed in the diaphragm deflection area and optionally adapted to the diaphragm guide rod. In this way, a homogeneous and reversible deformation of the diaphragm is obtained with minor wear as far as possible. At the end of the delivery process of the diaphragm pump, the diaphragm is applied to the arched, half-shell-shaped fluidization surface in an extensively flat manner, and a small dead volume can be obtained, which results in minimal space for pulverized materials with a high delivery rate and little high-pressure gas loss.Type: GrantFiled: July 29, 2021Date of Patent: February 28, 2023Assignee: Dipl.
