The carbon black dust removal device of the charging door of the internal mixer

Abstract

The invention relates to a carbon black dust exhausting device of a mixer loading door, and belongs to the technical field of mixers. The device comprises an air exhaust pipeline, a mixer loading door body, a feeding door, a rotating shaft, a telescopic rod and a telescopic air cylinder and further comprises a connecting layer, a lower wall plate and a pipeline; the lower wall plate is arranged below the feeding door, and is parallel to the section of the mixer loading door body, one end of the connecting layer is connected with the feeding door, the other end of the connecting layer is connected with the lower wall plate, the upper end of the pipeline is communicated with the air exhaust pipeline, and the lower end of the pipeline is communicated with the bottom of the mixer loading door body. The gap of the lower half portion of the loading door is sealed, a seal device of a triangular prism is formed, meanwhile, through the pipeline, the seal device is communicated with a dust exhausting pipeline on the upper portion of the loading door, shortcomings existing in an existing device are successfully overcome, carbon block is prevented from flying into the air, the pollution to the environment is avoided, meanwhile, the recycled carbon black can be recycled, and waste is prevented.

Description

technical field [0001] The invention relates to a device for discharging carbon black and dust at a feeding door of an internal mixer, in particular to a device with good sealing effect and environmental protection, which belongs to the technical field of internal mixers. Background technique [0002] In the prior art, the feeding door of the masterbatch internal mixer in the internal mixing workshop is a part of the internal mixer feeding device, such as figure 2 As shown, the feeding device is composed of an air extraction pipe 1, a feeding door body 2 of the internal mixer, a feeding door 3, a rotating shaft 4, a telescopic rod 5 and a telescopic cylinder 6, and the feeding door 3 is located at the front of the mixing chamber of the internal mixer. In the front, there is a dust exhaust cover on the upper part of the feeding door 3, which is used to extract the carbon black leaked from the gap of the feeding door, and there is no device below the feeding door 3.

AI Technical Summary

Problems solved by technology

[0003] The unfavorable factors of the device of this feed door 3 are as follows: the dust exhaust cover on the upper part of the feed door 3 can only extract the carbon black leaked from the gap in the upper half of the feed door 3, while the carbon black leaked from the gap in the lower half of the feed door 3 is difficult to extract. Extraction, the exposed carbon black either sinks to the platform next to the internal mixer, or floats in the air, causing serious pollution to the environment
