Device for jointing dust removing air pipes of movable discharging carriage, dust removing system and method for jointing air pipes

Abstract

The invention discloses a device for jointing dust removing air pipes of a movable discharging carriage, which comprises a fixed jointing pipe fixed on a main air pipe in a factory, and a movable jointing pipe arranged on the movable discharging carriage. The jointing ends of at least one of the two kinds of jointing pipes are provided with elastic flexible sections, and the two kinds of jointing pipes are mutually pressed and closely contacted through the elastic flexible sections when the two kinds of jointing pipes are jointed. The device has the advantages of simple structure, capability of avoiding jointing gaps, no air drafting pressure loss, good dust removing effects, and improvement on operational environment of workers. The invention also discloses a dust removing system of the movable discharging carriage, and the system is provided with the device for jointing the dust removing air pipes of the movable discharging carriage. The invention also discloses a method for jointing the dust removing air pipes of the movable discharging carriage. According to the method, the jointing is realized by using the device for jointing the dust removing air pipes of the movable discharging carriage, the movable discharging carriage drives to a discharging point during jointing, and the movable jointing pipe and the fixed jointing pipe are mutually pressed so as to form sealing by using elasticity of the elastic flexible sections.

Description

technical field [0001] The invention relates to mobile unloading and dust removal equipment, in particular to a butt joint device for a dust removal air duct of a mobile unloading vehicle, a dust removal system and an air duct butt joint method. Background technique [0002] Some mineral storage workshops are equipped with a mobile unloading and dust removal system. The head of the mobile unloading vehicle of the dust removal system is equipped with a mobile butt joint that can move with the vehicle. There is a fixed butt pipe on the main air duct corresponding to each mine bin in the workshop, and an electric valve is installed at the interface of the fixed butt pipe. When the mobile unloading truck moves to a certain mine bin to unload, First, connect the mobile butt joint at the head of the mobile unloading truck with the fixed butt joint at the mine bin, and open the electric valve there (the electric valve at the fixed joint at other mines remains closed), and then star...

AI Technical Summary

Problems solved by technology

First of all, considering that there is inevitably a certain error in the elevation of the track of the mobile unloading vehicle during installation, this error may cause collisions between the fixed docking pipe and the mobile docking pipe during docking. Leave a certain gap, and use this gap to "absorb" the elevation error of the track to ensure the smooth passage of the mobile unloading vehicle, but this structure makes there must be a certain axial gap between the fixed butt joint and the mobile butt joint, resulting Strict docking cannot be achieved; at the same time, due to the error between the actual installation position of the fixed butt joint pipe and the mobile butt joint pipe and the design parameters, and there is also an error between the position where the mobile unloading When docking, there must be a certain radial gap. To reduce the radial gap, the position of the moving trolley must be manually adjusted by the worker. The operation is troublesome and affects the progress of unloading, and manual adjustment may not completely eliminate the radial gap. The radial gap is eliminated, and the axial gap still exists, which makes the dust removal system inhale a large amount of wild wind in the gap during unloading, resulting in a large pressure loss, making the main air duct insufficient for the suction of the mobile butt pipe, resulting in dust removal The effect is not good, which seriously affects the operating environment of the workers on the job
