Description

  • The present invention is new construction of the silo funnel with external ring in particular designer for storage of bulk materials, especially of bulk density to 0,9 kN/m3.
  • The present invention relates to a cylindrical tank of vertical axis.
  • There is well-known construction of silos which are storage containers of bulk materials, especially for agriculture. Storage containers comprises funnels at bottom part of construction which are using for controlled discharge. One of known construction issue at his kind of storage containers are compressive forces in the funnel. In practice there are known the funnel of the silos in which for transfering compressive forces heavy metallurgical profiles are using. Metallurgical profiles requires mechanical processes for forming ring shapes which later are subjected of long and tedious welding processes. This kind of funnel design requires using of thick and heavy metal sheet which increases weight of construction and costs.
  • The funnel of silo comprises metal sheets supproted by constraction composed of pillars, brace and stiffering according to invention consists of peripheral profile on circle or polygon shape and is external ring of the funnel of silo, suspended linker for funnel at bracket section profile and also funnel tapes and spout funnel, wherein spout funnel is connected by screws, throught funnel tape with funnel pillars stiffened by braces, and stifferings, and funnel tapes are covered by metal sheets of the plating funnel and mounted by screws.
  • Peripheral profile has cross-section shape of circle, or double T or rectangular or polygonal.
  • Suspended linker for funnel has bracket section shape at angel of aperture from 100° to 179°.
  • Tapes have elongated trapezoid shape at thickness from 1,2 to 3,5 mm.
  • Metal sheets of the plating funnel and funnel tapes are continuous or separated into sections.
  • The new design of the funnel reduces energy used during welding process and material losses during manufacturing metal sheet which combined sheathing funnel with cylindrical part of silo. Construction also guarantees the effective using of metal sheets and profiles and also give possibility of space optimalization during transport. Due to reduce of thickness metal sheets from 33% to 52% sheathing of funnel, constraction features a simple of manufacturing of individual elements and easy of finalizing construction on building area. This kind of construction has very similar construction to cone shape which fully utilizes the membrane state i.e. complete utilization of principal stresses on both direction omnited the bending stiffness and eliminated maintenance and stood over of grain on the connection of funnel with cylindrical part of silo. The screws using allows for easy funnel reparing.
