Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust collectors, in particular to a dust unloading device for a pulse dust collector. Background Art

[0002] Pulse dust collector is a kind of equipment used to remove and collect dust generated in industrial production. Its working principle is as follows: when dust-laden gas enters the dust collector from the air inlet, it first hits the inclined plate and baffle in the middle of the air inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down. Due to the inertia, the coarse dust particles in the gas flow directly into the ash hopper, which plays the role of pre-dust collection. The airflow entering the ash hopper then turns upward and passes through the dust filter bag with a metal skeleton inside, and is captured on the outer surface of the filter bag. The purified gas enters the cleaning room above the filter bag chamber and is collected in the The dust-laden gas is discharged from the air outlet. During the purification process through the filter bag, as time goes by, more and more dust is deposited on the filter bag, which increases the resistance of the filter bag and causes the air volume to gradually decrease. For normal operation, the resistance must be controlled within a certain range. Once the range is exceeded, the filter bag must be cleaned. During cleaning, the pulse controller sequentially triggers each control valve to open the pulse valve. The compressed air in the air bag is sprayed from each hole of the spray pipe through the venturi tube into each corresponding filter bag. The filter bag expands sharply in an instant, causing the dust deposited on the surface of the filter bag to fall off, and the filter bag returns to its initial state. The cleaned dust falls into the ash hopper and is discharged from the machine body through the ash discharge system. In this way, the dust deposited on the filter bag is periodically pulse-blown and cleaned, so that the purified gas passes normally and the dust removal system is guaranteed to operate.

[0003] In current practical applications, there are usually many pulse dust collectors in large factories, and a large dust discharge system needs to be set up. The dust collected by each pulse dust collector is discharged into the dust collection pipe in order according to the process, and finally transported to the dust collection facility through augers, bucket elevators, etc. However, there are fewer pulse dust collectors in small factories. For economic reasons, a detachable dust box is usually set at the ash outlet at the lower end of the pulse dust collector to collect dust. When the dust is almost full, it is manually removed and transferred one by one for processing, and then the emptied dust box is installed back to the ash outlet. This is not convenient to operate; and the equipment needs to be shut down from the time the worker removes the dust box to the time the worker reinstalls it, which affects the production and processing efficiency.
