Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a high-efficiency pulse jet filter cartridge dust collector. Background Technology

[0002] A cartridge dust collector is a device used to treat industrial waste gas. It separates and filters particulate matter from dust-laden gas using the filtration properties of the filter cartridge material, thereby purifying the gas and achieving dust removal. A cartridge dust collector typically consists of an inlet, filter elements, and an outlet. Dust-laden gas enters the cartridge dust collector through the inlet, and after filtration and separation by the material in the filter cartridge, the purified gas flows to the outlet. The particles retained on the filter cartridge are cleaned by a dust removal device.

[0003] Patent CN222358152U discloses a cartridge dust collector that uses a hydraulic rod to drive a cleaning brush to clean the inner wall of the dust collection box, achieving a certain dust removal effect. However, this solution still has the following shortcomings: the cleaning component relies on a separate hydraulic rod for driving, requiring an additional power source, increasing energy consumption and structural complexity; dust removal requires manual operation, and dust accumulation can easily clog the lower dust hopper, affecting the continuous operation of the equipment.

At the same time, the high-pressure airflow passes through the pneumatic piston mechanism, which drives the movable frame 8 downward. The movable frame 8 drives the cleaning brush 9 to move downward synchronously, removing the dust from the inner wall. The dust falls into the discharge hopper 12. When the movable frame 8 moves downward, the cleaning brush 9... The movable frame 8 pushes the valve plate 13 to open, and the dust in the hopper 12 flows out from the opening of the hopper 12. After the blowing is finished, the pneumatic piston mechanism drives the movable frame 8 to move upward, and the valve plate 13 resets and closes. This utility model does not require additional hydraulic power. It uses the blowing airflow to synchronously drive the pneumatic piston mechanism, so that the cleaning brush 9 scrapes off the dust on the inner wall of the filter cartridge 7 while cleaning the dust. The dust removal efficiency is increased by 30% and the energy consumption is reduced by 25%. When the movable frame 8 moves downward, it triggers the valve plate 13 to realize the automatic discharge of dust during the blowing process, avoiding manual operation and dust hopper blockage. The continuous running time of the equipment is extended by 40%.

The bottom wall of the cylinder 17 is fixedly connected; the high-pressure gas from the air tank 11 of this utility model is sprayed onto the filter cartridge 7, shaking off the surface dust; at the same time, the high-pressure airflow drives the piston 18 downward through the air pipe 16, the piston 18 drives the piston rod 10 downward, the piston rod 10 drives the movable frame 8 downward, the movable frame 8 drives the cleaning brush 9 to move downward synchronously, removing the dust on the inner wall, and the dust falls into the hopper 12. When the movable frame 8 moves downward, it pushes the valve plate 13 to open, and the dust in the hopper 12 flows out from the opening of the hopper 12; after the blowing is finished, the piston 18 moves upward under the action of the return spring 20, the piston 18 drives the piston rod 10 upward, and the piston rod 10 drives the movable frame 8 upward to the initial position.
