Description

Technical Field

[0001] This utility model relates to a wear-resistant dust collector cage, belonging to the technical field of dust collector cages. Background Technology

[0002] Baghouse dust collectors are a type of high-efficiency and widely used industrial flue gas purification equipment. Their core components are filter bags and the bag cages that support the filter bags (also known as dust collector frames or filter bag frames).

[0003] The main function of a bag cage is to provide a precise and stable support structure for flexible filter bags, preventing them from collapsing, twisting, or excessively deforming during filtration (especially during dust removal). This ensures effective utilization of the filtration area and unobstructed airflow, while protecting the filter bags from mechanical damage, thereby guaranteeing dust removal efficiency and extending the service life of the filter bags. For example, utility model patent CN221333204U discloses a dust collector cage, which relates to the field of dust collector cage technology. It includes: a base with a circular cross-section in plan view, used to fix the device; longitudinal ribs assembled on the top of the base, with detachable longitudinal ribs connected to the top of the base, a total of sixteen longitudinal ribs arranged around the circumference; and transverse ribs assembled on the top of the base, with the transverse ribs fixedly connected to the longitudinal ribs by welding, used to fix the longitudinal ribs; the longitudinal ribs include: longitudinal portions assembled at the upper and lower ends of the longitudinal rib, with longitudinal portions provided on both the upper and lower sides of the longitudinal rib; and arc-shaped portions assembled in the middle of the longitudinal rib, with the upper and lower longitudinal portions connected by the arc-shaped portions, the arc-shaped portions being concave inwards, and the longitudinal portions and arc-shaped portions being integrally formed; the longitudinal ribs are symmetrical in shape; and transverse ribs are provided at the junction of the longitudinal portions and the arc-shaped portions. However, the above solution has the following shortcomings in practical use: The aforementioned device is a fixed structure. In order to ensure that it can always maintain the shape, tension and dimensional stability required by the design during operation, the dust bag is a non-elastic structure. Therefore, the installation of the device is relatively difficult because the dust bag cannot deform when it is put on. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wear-resistant dust collector bag cage, which achieves... The technical solution adopted by this utility model to solve its technical problem is: A wear-resistant dust collector cage includes an installation cylinder, wherein multiple installation rings are fixedly connected to the outer wall of the installation cylinder, the multiple installation rings are coaxially distributed, and multiple abutment rods are provided on the outer periphery of the installation cylinder; The mounting ring is hinged to the outer circumference with a plurality of hinge rods, and each of the hinge rods is hinged to a connecting rod at its end.

Both the first and second limiting components are matched with the limiting rod; At the top of the fixed mounting cylinder, under the action of gravity, multiple abutment rods approach and hang on the outer periphery of the mounting cylinder. At this time, multiple hinge rods are tilted. Then, multiple abutment rods are inserted into the dust bag, and the bottom of multiple abutment rods abuts against the bottom of the dust bag. Then, the mounting cylinder is moved downward, and multiple hinge rods will rotate around the hinge axis until multiple abutment rods unfold outward and abut against the inner wall of the dust bag. During this process, multiple hinge rods rotate to a horizontal state. By rotating the rotating rod, multiple limiting rods can be driven to rotate simultaneously until multiple limiting rods are respectively engaged with multiple first limiting parts and multiple second limiting parts.

The two sliders are slidably connected to two grooves respectively. Two locking rods are fixedly connected to the top of the movable ring. The two locking rods are respectively matched with two locking grooves. By rotating the locking sleeve in the forward direction, the locking sleeve can move upward around the outer circumference of the mounting cylinder. At this time, the locking sleeve will drive the moving ring to move upward until the two locking rods at the top of the moving ring are inserted into the two locking slots respectively, thereby completing the locking of the rotating disk and the rotating rod.

[0008] Preferably, the outer periphery of the rotating disk is provided with anti-slip grooves, and the number of anti-slip grooves is set to multiple, with the multiple anti-slip grooves distributed around the center of the rotating disk; By setting multiple anti-slip grooves on the outer circumference of the rotating disk, the friction between the rotating disk and the user's palm can be increased, thus facilitating the rotation of the rotating rod.

Afterward, pressing the mounting cylinder unfolds the dust bags, causing the abutments to extend outward and support the dust bags. A fixing mechanism can be used to secure the unfolded, supported dust bags. Attached Figure Description
