Gas-solid dust sealing device

Abstract

The invention discloses a gas-solid dust sealing device. The gas-solid dust sealing device comprises a building platform, an ash silo, a penetrating opening and a steel wire rope, wherein the ash silo is arranged above the building platform, the penetrating opening is formed in the side wall of the ash silo, and the gas-solid dust sealing device further comprises a positive pressure tank, a tightening force tank and a negative pressure tank which sequentially communicate with one another in the radial direction, and the penetrating opening is detachably connected with the positive pressure tank; one end of the steel wire rope sequentially penetrates through the negative pressure tank, the tightening force tank, the positive pressure tank and the penetrating opening and then extends into the ash silo; a sealing pipe is arranged in the positive pressure tank, a plurality of sealing holes are formed in the sealing pipe, and a pipeline I is arranged on the positive pressure tank to communicate with a positive pressure air source; an upper pressing ring and a lower pressing ring are elastically connected into the tightening tank, the space between the upper pressing ring and the lower pressing ring is filled with rock wool, and the steel wire rope is tightly wrapped with the rock wool; and a pipeline II is arranged on the negative pressure tank to communicate with a negative pressure air source. Through a three-stage sealing structure, it is effectively guaranteed that dust does not overflow, it is guaranteed that dry ash filling operation meets the environmental protection requirement, the actual production requirement of an enterprise is met, and good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of sealing and dust removal, in particular to a gas-solid dust sealing device. Background technique [0002] The dry ash stored in the ash silo needs to be filled with the help of a dry ash bulk machine. The dry ash bulk machine transfers it from the bottom of the ash silo to the ash tank truck. There is an expansion joint at the bottom of the ash silo, and the wire rope is pulled by the tractor. The wire rope One end of the shaft goes through the ash storehouse and then connects downward to the expansion joint, and then the tractor controls the retraction and release of the steel wire rope to achieve the function of adjusting the height of the expansion joint, so that the expansion joint is compatible with the gray tank truck. [0003] During the dry ash filling process, the dust in the ash silo will continuously spray out from the junction of the steel wire rope and the ash silo, causing ash leakage and as...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the dust is easy to leak from the junction of the steel wire rope and the ash silo, the present invention provides a gas-solid dust sealing device. By adding a sealing structure at the junction of the steel wire rope and the ash silo, the dust is not leaked and the use of the steel wire rope is improved. life
