Filter bag processing need attention
Description:INTRODUCTION
Filter bag is the core of the dust filter components. The filter bag has the strict requirements on design, filter material cutting, woven technology etc. These requirements are very important for the normal operation of the bag filter and convenient maintenance, and it is great significance to enlong the service life of the filter bag.
Structure and application
Filter bag are composed by woven filter material bag body and supported in role, snap ring, clamp, chain hoist, etc. The rest of the filter bag dust collector and its accessories are the venturi tube, frame, mouth of elastic ring, etc.
Specifications
The diameter of the filter bag is 115-200mm, length is 2000 - 9000mm, the specifications of the commonly used filter bag is 120 - 160 mm diameter, 2000 ~ 6000mm length.
Filter bag processing matters that should be paid attention:
After the selection of filter bag material and determine the
specifications of the filter bag, we will process the filter bag as
following attention matters:
(1) Precise design required size of the filter cloth for filter bag
parts, the filter cloth will larger than the actual amount design
size, to leave a spare for weaving.
(2) To choose the right filter bag accessories, specifications and
check its quality. The filter bag accessories should match the
filter bag quality requirements.
(3) We make the filter bag line drawing, cutting, sewing on automatic production line. When the filter bag need manual processing, we will open it on the operation platform, and with certain pulling force to keep it is flat.
(4) We keep the strict processing quality standards, according to
design drawings and operation process. Our worker meet the
requirements of tooling and clothing shoes and hats, no smoking.
