The invention relates to the technical field of cloth bag dust removal, and concretely relates to an industrial bag-type dust collector. The dust collector comprises a dust removal box, a dust removalmechanism is fixedly connected to the inner wall of the upper end of the dust removal box, a blocking mechanism is fixedly connected to the inner wall of the lower end of the dust removal box, a linkage mechanism is fixedly connected to the upper surface of the blocking mechanism, a connecting rod is driven to rotate through an arranged turntable, the connecting rod drives a clamping strip to rotate, the clamping strip is clamped in a clamping groove, a lifting block is driven to rotate through the clamping strip and the clamping groove, the lifting block drives a round block to rotate, the round block drives a dust baffle to rotate, when a fixing rod is in contact with a first stop lever, the dust baffle blocks a dust falling hole, when the fixing rod makes contact with a second stop lever, the dust baffle is moved away from the upper end of the dust falling hole, then falling dust can be swept into the dust falling hole through rotation of the dust baffle, then the dust falling holeis blocked through the dust baffle, the dust is prevented from being driven by waste gas to move into a cloth bag again, and the filtering efficiency of the waste gas is prevented from being affectedby the cloth bag.
