Dry ash sealing and telescopic bulk device

Abstract

The invention discloses a dry ash sealing telescopic bulk device, and relates to the technical field of dry ash conveying. The dry ash sealing telescopic bulk device comprises a discharging pipe and a tank car, wherein a feeding hole is formed in the middle end of the top of the tank car, six groups of telescopic sleeves are arranged at the bottom of the discharging pipe, the bottoms of the inner walls of the upper group of telescopic sleeves make contact with the outer walls of the tops of the lower group of telescopic sleeves in an attached mode, the bottom of the telescopic sleeve at the lowest end is fixedly connected to a discharging inner ring, the outer wall of the upper end of the discharging pipe is fixedly connected to a dust collection sleeve, the top of the dust collection sleeve is fixedly connected to a straight pipe, the straight pipe is connected to a filtering structure used for filtering dust, the filtering structure has a blockage clearing function, the top of the straight pipe is in threaded connection with the straight pipe, and the side wall of the straight pipe is fixedly connected to a supporting ring. According to the above solution, no gap exists after each stage of telescopic sleeves is expanded, so that dry ash does not escape due to the existence of pressure difference in the falling process of the discharging pipe.

Description

technical field [0001] The invention relates to the technical field of dry ash transportation, in particular to a dry ash sealing and shrinking bulk device. Background technique [0002] At present, the bulk device for dry ash is mainly composed of a discharge pipe, a vacuum pipe and a dry ash transport vehicle box. The dry ash enters through the inner pipe. Due to the existence of gaps between the folded cone pipes, the dry ash flows during the descent process. Being sucked in by the dust suction fan, the dry ash cannot completely fall into the tank car box, thereby reducing work efficiency and secondary waste. There is a large amount of dry ash escaping between the inner and outer pipelines, and there are dry ash being sucked back and Dust is emitted, resulting in low filling efficiency. [0003] Therefore, in order to improve work efficiency and prevent dry ash from being sucked back and blown out, it is necessary to design a dry ash sealing and shrinking bulk device to ...
