Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a large bag dust collector convenient for discharging materials. Background Art

[0002] The bag dust collector is a dust collection method, which has gradually replaced the electrostatic dust collector. Most parts such as cement mills, raw material mills, coal mills, dryers, and kiln tails use bag dust collectors. The dust collection efficiency of the bag dust collector can reach more than 99%, the dust concentration of the purified gas is less than 50mg / Nm3, and its safety is better than that of the electrostatic precipitator.

[0003] Currently, large bag dust collection equipment is basically used in industrial fields such as cement and coal mines. After long-term use, a large amount of powder will accumulate inside the hopper, so it is necessary to discharge and clean the materials regularly. Although the existing bag dust collectors also have the function of discharging materials, there are still obvious defects in practice, such as:

[0004] When the existing bag dust collection equipment discharges materials, most of them open the opening at the bottom to let the powder slide down by its own weight. However, when the powder accumulates too much, it will coagulate into blocks due to factors such as humid environment, resulting in blockage during discharging, and manual dredging by workers is required, which not only has low efficiency but also increases the labor intensity. Therefore, the utility model provides a large bag dust collector convenient for discharging materials to solve the deficiencies in the prior art. Content of the Utility Model

The discharging arm 6 is provided inside the hopper 3, and the discharging arm 6 is in contact with the inner wall of the hopper 3. The rotary connecting member 5 is rotatably installed on the discharging outlet 301 at the lower end of the hopper 3. The discharging arm 6 is installed with the rotary connecting member 5. A driving member 4 is provided on the outer wall of the hopper 3, and the driving member 4 drives the rotary connecting member 5 to rotate on the discharging outlet 301 at the lower end of the hopper 3. The discharging arm 6 includes an arm rod and a scraper 601. An installation groove is provided on the arm rod, and the scraper 601 is detachably provided in the installation groove. The scraper 601 is in contact with the inner wall of the hopper 3.

[0023] When the large bag dust collector that facilitates discharging of the present utility model discharges the ash in the hopper 3, first, most of the unbonded dust in the hopper 3 will automatically fall under the action of gravity and then be discharged from the discharging outlet 301. For the dust adhered to the inner wall of the hopper 3, by starting the driving member 4, the rotary connecting member 5 can be driven to rotate. Then, the discharging arm 6 connected to the rotary connecting member 5 scrapes the dust on the inner wall of the hopper 3 through the scraper 601 on the arm rod, realizing full discharging.
