Three-phase foam sealing pressure relief and dust suppression equipment and material transfer equipment including the equipment

Abstract

The invention relates to material transfer equipment, in particular to three-phase foam sealing, pressure relief and dust suppression equipment. The three-phase foam sealing, pressure relief and dust suppression equipment comprises a first foam dynamic raft type check curtain, a second foam dynamic raft type check curtain, a foam sealing skirtboard, a foam spring pressure relief device and a foam liquid preparation unit. Each foam dynamic raft type check curtain comprises multiple raft pieces rotationally connected with a pipe body. Each raft piece is provided with a first through hole and grooves. Multiple second through holes are formed in each pipe body along the peripheral face of the pipe body, and the second through holes of each pipe body communicate with the corresponding first through holes. The foam sealing skirtboard is provided with a first columnar portion and a second columnar portion, the first columnar portion is provided with ceramic pipes, and multiple cavities used for containing foam liquid are formed between the second columnar portion and the first columnar portion. A foam liquid spray opening, a fixed set, a spring set, a foam disc, a first fixed pulley, a drive motor, a second fixed pulley and a water outlet used for pipeline washing re arranged at the position, close to a first end opening, of the foam spring pressure relief device. According to the three-phase foam sealing, pressure relief and dust suppression equipment, sealing of a guide chute can be dynamically guaranteed for a long time, dust overflow can be dynamically suppressed for a long time, and the positive pressure of the guide chute can be greatly reduced.

Description

technical field [0001] The invention relates to the field of material transfer equipment, in particular, but not exclusively, to a three-phase foam seal venting and dedusting equipment. Background technique [0002] In the process of material transfer, serious dust pollution will be produced, which will bring serious harm to safety production and staff health. Producers have made various attempts in dust control, such as replacing dust removal equipment and installing spray systems. However, through these dust control methods, the dust concentration of the transfer equipment still exceeds the standard, especially the dust at the exit of the guide chute of the crusher room transfer station is seriously exceeding the standard. After the belt conveyor of the transfer station is running, obvious dust accumulation can be seen on the ground. [0003] The generation process of dust pollution is as follows: [0004] The material enters the transfer equipment from the head guard o...

AI Technical Summary

Problems solved by technology

The dust-blocking rubber curtain at the material guide outlet is also unable to restrain the leaked dust due to the strong induced wind

Therefore, the current seal box dust suppression equipment for the material guide trough of the belt conveyor cannot dynamically and long-term suppress the dust overflow of the material guide trough, which will cause serious environmental, safety problems and economic losses
