Problems solved by technology

However, this unloading method determines that the hanging bag centrifuge is only suitable for separating suspensions containing high solid phase looseness, moderate particle size, and difficult to compress, while separating some suspensions containing finer solid phase particles and higher viscosity At the same time, due to the action of strong centrifugal force, the solid phase forms a tightly structured filter residue layer in the filter bag, and the filter bag is closely attached to the inner wall (or liner) of the drum body, making it difficult to remove the filter when unloading. The bag is lifted out of the drum, and if the force is too great, the filter bag may even be torn
This limits the scope of use of the hanging bag centrifuge

Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the bag extrusion device in the bag-hanging centrifuge of the present invention includes: a drum 5, and the drum 5 further includes: a drum body 51 and a drum bottom 52, and the drum bottom 52 is arranged on the main shaft 7 , the main shaft 7 is movably arranged on the base 14 through the bearing seat 15, a filter bag 6 is arranged in the drum 5, and a semi-open annular airbag 8 is arranged on the inner wall of the drum body 51, and the specific setting method is: the annular airbag 8 The joint with the inner wall of the drum body 51 is pressed by the pressure ring with screws, and the position where the drum body 51 fits with the annular air bag 8 and the part covered by the annular air bag 8 on the drum body 51 does not have filter holes. The annular airbag 8 forms an air cavity together with the inner wal...

Abstract

The present invention discloses a bag extruding device in a punching-bag centrifuge, which can make a filter residue layer crack or loosen so as to produce a clearance between the interior wall of a rotary drum and a filter bag, which is beneficial to unloading. The present invention comprises a rotary drum. The filter bag is arranged in the rotary drum. An annular air bag is arranged on the interior wall of the rotary drum. An air inlet of the annular air bag is fixed on the wall of the rotary drum. A machine shell is equipped with an air inlet device cooperating with the air inlet. The filter bag is arranged at the internal side of the annular air bag. With the present invention, a clearance can be produced between the filter bag or the annular air bag and the rotary drum wall (or a lining net), so the lifting mechanism can lift the filter bag out of the rotary drum for material unloading easily.

Description

technical field [0001] The invention relates to a hanging bag centrifuge, in particular to a bag squeezing device for cracking or loosening the filter residue layer by squeezing the filter bag in the hanging bag centrifuge. Background technique [0002] The hanging bag centrifuge is a major improvement over the traditional three-legged filter centrifuge. By adopting the unloading method of lifting the filter bag and the filter residue from the drum, the unloading process becomes very convenient and the filter bag is cleaned. It is also very convenient, thereby improving production efficiency and reducing labor intensity; it also avoids the pollution and scattering of finished products caused by manual unloading, and is widely used in chemical, light industry, pharmaceutical, food and other industries. However, this unloading method determines that the hanging bag centrifuge is only suitable for separating suspensions containing high solid phase looseness, moderate particle s...
