Description

Technical Field

[0001] This utility model relates to the field of filter cartridge structure technology, specifically a filter cartridge structure for a dust collector. Background Technology

[0002] Industrial production processes generate large amounts of dust-laden gas. Direct release of this gas into the atmosphere can cause serious environmental pollution and harm human health. Therefore, dust collectors are necessary to purify these gases. Cartridge dust collectors, as a common type of dust removal equipment, are widely used in various industries due to their advantages such as large filtration area, high filtration efficiency, and small footprint. The filter cartridge is one of the key structural components of a dust collector. Existing filter cartridge structures face several problems during use. On the one hand, filter cartridge replacement is cumbersome, usually requiring the disassembly of multiple parts, which not only wastes time and manpower but also increases equipment downtime and affects production efficiency. On the other hand, during dust collector operation, the filter cartridge may shift due to airflow impact and equipment vibration, leading to decreased filtration efficiency or even damage to the filter cartridge and shortening its service life. Therefore, a new filter cartridge structure for dust collectors is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a filter cartridge structure for a dust collector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter cartridge structure for a dust collector, comprising a lower plate and a cover plate. An air outlet is provided on the lower surface of the lower plate. An outer limiting sleeve and an inner limiting sleeve are fixedly connected to the upper surface of both the lower plate and the lower surface of the cover plate. The outer limiting sleeve is located around the inner limiting sleeve. Two vertical rods are symmetrically fixedly connected to the upper surface of the lower plate. A connecting sleeve is fixedly connected to the top of each vertical rod. A insert sleeve is inserted into the inner side wall of the connecting sleeve. A rotating rod is rotatably connected to the upper surface of the cover plate via a bearing. The rotating rod penetrates the lower surface of the cover plate and extends into the insert sleeve. Two rotating plates are symmetrically fixedly connected to the bottom of the outer side wall of the rotating rod. Two sliders are symmetrically slidably connected to the outer wall of the insert. A wedge is fixedly connected to the opposing side of each slider. The lower surface of the wedge is a smooth inclined surface. Two slots are symmetrically opened on the outer wall of the connecting sleeve. A transmission rod is hinged to one end of the rotating plate. The end of the transmission rod away from the rotating plate is hinged to the outer wall of the slider. A coarse filter and a fine filter are provided above the lower plate. The coarse filter is located around the fine filter. The coarse filter is inserted into the inner wall of the outer limiting sleeve. The fine filter is inserted into the inner wall of the inner limiting sleeve. Two movable plates are symmetrically fixedly connected to the outer wall of the slider. A spring is fixedly connected between the movable plate and the inner wall of the insert.

[0005] As a further preferred embodiment of this technical solution: a throttle handle is fixedly connected to the top end of the throttle rod.

[0006] As a further preferred embodiment of this technical solution, a handle is fixedly connected to the upper surface of the cover plate.

[0007] As a further preferred embodiment of this technical solution, the coarse filter cartridge is made of large-pore polyester fiber filter media.

[0008] As a further preferred embodiment of this technical solution, the fine filter cartridge uses small-pore PTFE membrane filter media.

[0009] As a further preferred embodiment of this technical solution: the lower plate, the cover plate, the outer limiting sleeve, and the inner limiting sleeve are all made of stainless steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are: When installing the cover plate, the insert sleeve is inserted into the connecting sleeve. The wedge block is compressed back into the insert sleeve, and the spring is stretched. When the wedge block is fully aligned with the slot, the spring shortens and drives the wedge block to insert into the slot, realizing the connection and locking between the insert sleeve and the connecting sleeve, thus completing the quick installation of the cover plate. The air first passes through the coarse filter cartridge to filter coarse dust particles, and then passes through the fine filter cartridge to filter fine dust particles. Through dual-stage filtration, the filtration efficiency is improved. After the cover plate is installed, the outer and inner limiting sleeves limit the coarse and fine filter cartridges to prevent them from shifting, ensuring the filtration effect. When the filter cartridge needs to be replaced, the rotating rod is rotated counterclockwise to drive the rotating plate to rotate. The rotating plate pulls the transmission rod, and the transmission rod pulls the wedge block away from the slot, releasing the lock between the insert sleeve and the connecting sleeve. This allows for quick removal of the cover plate and replacement of the filter cartridge. No tools are required, and the operation is simple and quick, realizing the rapid replacement and stable operation of the filter cartridge. Attached Figure Description
