Abstract
The lifting type dust collecting device comprises a portal frame and a dust collecting cover with a downward opening mounted at the top of the portal frame, wherein the dust collecting cover is mounted with the portal frame in an up-and-down moving mode, a lifting motor is fixedly mounted on the outer side of the portal frame, a pull rope is wound at the output shaft end of the lifting motor, and the upper end of the pull rope is wound at the top of the portal frame and fixed with the dust collecting cover. The furnace mouth at the top of the smelting furnace can be completely covered and buckled, smoke dust generated in the smelting process is prevented from leaking into the atmosphere, the environment is prevented from being polluted, and the workshop operation environment is improved.
Description
Technical Field
The utility model relates to a ferromolybdenum smelting uses dust collecting device, especially relates to an over-and-under type dust collecting device.
Background
In the ferromolybdenum smelting process, in order to avoid the emission of smoke and dust generated in the smelting process to the atmosphere, a dust collecting device connected with a smoke and dust filtering system is required to be additionally arranged on the smelting furnace. The existing dust collecting device mainly comprises a portal spanning two sides of a smelting track and a dust hood fixedly mounted at the top of the portal, during smelting operation, a smelting furnace is moved to the lower part of the dust hood through the smelting track by a rail car, and under the negative pressure action of a smoke filtering system, smoke generated by the smelting furnace is collected by the dust hood and enters the smoke filtering system for processing. Because the height uncertainty of railcar and smelting furnace, the dust cage height of fixed mounting at portal top is unadjustable, leads to having great difference in height between smelting furnace and the dust cage, and the smoke and dust that produces among the smelting process leaks to the atmosphere by very big part in, the polluted environment influences workshop operation environment.
Disclosure of Invention
The utility model provides a solve above-mentioned technical problem, provide an over-and-under type dust collecting device, it can cover the fire door at smelting furnace top completely and detain, avoids the smoke and dust that produces among the smelting process to leak the atmosphere in, avoids the polluted environment, improves workshop operation environment.
The technical solution of the utility model is that:
over-and-under type dust collecting device, including the portal, at the downward dust cage of portal top installation opening, its special character lies in: the dust hood is vertically and movably installed with the gantry, the lifting motor is fixedly installed on the outer side of the gantry, a pull rope is wound at the output shaft end of the lifting motor, and the upper end of the pull rope bypasses the top of the gantry and is fixed with the dust hood.
Preferably, a lifting frame which moves up and down is arranged in the door frame through a slide way, the dust collection cover is fixedly arranged on the lifting frame, and the upper end of the pull rope is fixed with the lifting frame.
Preferably, the dust hood is hemispherical, the structural strength is high, the gravity center height of the dust hood is reduced, and the up-and-down running stability of the dust hood is improved.
Further preferably, a guide wheel is mounted on the top of the gantry, and the pull rope is wound on the wire guide wheel.
The utility model has the advantages that:
because the dust hood is vertically and movably installed with the portal frame, the lifting motor is fixedly installed on the outer side of the portal frame, the output shaft end of the lifting motor is wound with a pull rope, and the upper end of the pull rope bypasses the top of the portal frame and is fixed with the dust hood. The lifting motor is started, the height of the dust hood is controlled through the pull rope, the dust hood is completely covered and buckled with the furnace mouth at the top of the smelting furnace, smoke generated in the smelting process is prevented from leaking into the atmosphere, the environment pollution is avoided, and the workshop operation environment is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-door frame, 2-lifting frame, 3-dust collecting cover, 4-lifting motor, 5-pull rope and 6-guide wheel.
Detailed Description
As shown in fig. 1, the lifting dust collecting device comprises a portal frame 1, a lifting frame 2 which moves up and down in the portal frame 1 through a slideway, a dust collecting cover 3 with a downward opening is fixedly installed on the lifting frame 2, the dust collecting cover 3 is hemispherical, a lifting motor 4 is fixedly installed on the outer side of the portal frame 1, a pull rope 5 is wound at the output shaft end of the lifting motor 4, a guide wheel 6 is installed at the top of the portal frame 1, and the upper end of the pull rope 5 is wound at the top of the portal frame 1 and fixed with the lifting frame 2.
During operation, firstly, the door frame 1 is spanned at two sides of the smelting track, the top end of the dust hood 3 is connected with a pipeline of the smoke and dust filtering system through the telescopic pipe, when the smelting furnace is smelted, the smelting furnace is moved to the lower part of the dust hood 3 through the smelting track by the rail car, then the lifting motor 4 is started, the smelting furnace hood is buckled by the falling dust hood 3, smoke and dust generated in the smelting process of the smelting furnace are collected by the dust hood 3, and the smoke and dust enter the pipeline of the smoke and dust filtering system through the telescopic pipe connected with the top end of the dust hood 3.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
