What is a filter cage with junction?

Filter cage with junction has a woven-wire junction, double ring and double groove, slip and twist lock bayonet assembly cages for large dust collectors.

Specifications

Item	Connection method	Describe
CAGE WITH WOVEN-WIRE JOINT		This type of woven-wire cage with joint can greatly facilitate installation and removal for replacement of the cage or filter sleeve within the baghouse air manifolds.
DOUBLE GROOVE JOINT CAGE		This type of easy-to-assemble cage is widely used in the asphalt, energy, cement and food industries.
DOUBLE RING JOINT CAGE WITH SAFETY COUPLING		This connection method is mainly used to facilitate transportation and quick assembly when the bag cage is too long.
ROTATING COUPLING JOINTED CAGE		This type of cage is suitable for industrial dust collectors with extensive dimensions. It unites the various parts of the cage through a joint that ensures the seal by means of rotation. Turning the two parts of the cage's joint results in one part fitting into the other and ensures easy installation and a guaranteed seal.
SLIDING COUPLING JOINTED CAGE		Some baghouses of certain vertical air dusting systems require long cages broken down into several parts with a joint that permits easy installation for maintenance workers.
JOINT CAGE WITH SIDE SPEINGS/HORNS		They are widely employed for the following filtrations: gas at high humidity and temperatures, corrosive gas as well as cohesive, explosive and abrasive powders.

FAQ

Q
What is a bag cage with connecting clips/rings? What problem does it primarily solve?
A
A bag cage with connecting clips/rings is a multi-section dust collector frame where each section is joined into a single unit using specialized metal connecting rings or clips. It primarily addresses the challenges of transporting, handling, and installing extra-long bag cages (typically over 2 meters). This design enables segmented manufacturing and rapid on-site assembly, significantly reducing damage risks and improving installation efficiency.
Q
Is this coupling connection method secure? Will it loosen under pulse cleaning impacts?
A
Extremely secure. Our coupling rings/clips are manufactured using precision stamping or spinning processes, ensuring a tight interlock with the end ports of each cage segment. Their design undergoes rigorous calculations to withstand continuous pulse jet impacts without loosening, guaranteeing structural strength and stability equivalent to monolithic cages.
Q
Is installing these multi-section cage assemblies complicated? Are special tools required?
A
Installation is straightforward and typically requires no special tools. Simply align the male connector of the upper section with the female connector of the lower section, then apply downward pressure until you hear a distinct “click” indicating full engagement. This can be done by a single operator, significantly reducing filter bag replacement time.
Q
Does the connector/ring design pose a risk of filter bag wear?
A
No. Our connector/ring design fully addresses this concern. All connection points feature smooth finishes with no sharp edges or burrs. The diameter at the connection matches the cage body, creating a seamless transition that completely eliminates the risk of additional wear on the filter bag interior.
Q
What filter bag shapes is this cage compatible with?
A
This connection technology is highly flexible and widely applicable to various cage shapes, including Round, Flat, and Oval cages, meeting the needs of different structural dust collectors.
