Description

Technical Field

[0001] The utility model relates to the field of dust removal, in particular to a device for online replacement of a back-blowing traction cable of a horizontal bag dust collector. Background Art

[0002] Faced with rising environmental standards, bag filters, as devices that efficiently capture and separate suspended dust particles in air or gas, have become a key component in meeting ultra-low emission standards and are highly competitive. Dust-laden gas enters the dust collector through the air inlet and, after passing through the guide plates, is slowed and evenly distributed. Dust particles are trapped on the surface of the filter bag due to inertia, gravity, and diffusion. Over time, more and more dust accumulates on the filter bag surface, gradually increasing the resistance of the dust collector. Existing bag cleaning methods mainly include manual tapping, pulse jet cleaning, and vibration cleaning.

[0003] Due to the structural constraints of horizontal bag filters, the main equipment of the backflush system is installed on the clean media side after filtration. Backflush cleaning is performed by pulling a pulse device left and right or up and down using a steel cable. Due to the high temperature and corrosive effects of boiler flue gas, the pulling cable is prone to corrosion, damage and breakage, resulting in a short cable life. Cable replacement requires the boiler to be shut down, making maintenance inconvenient and resulting in significant economic losses. Utility Model Content

[0004] In order to solve the defects of the existing horizontal bag dust collector that the boiler needs to be shut down and maintenance is inconvenient when replacing the rope, the purpose of the utility model is to provide a device for online replacement of the back-blowing traction rope of the horizontal bag dust collector.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a device for online replacement of the back-blowing traction cable of a horizontal bag dust collector, comprising a clean flue gas chamber 1, an electric drum 2, a steel cable 3, a pulley 4, a back-blowing air box 5, a traction trolley 6, dust removal bags 7, a back-blowing air cylinder 8, a sealing box 9, a connecting rod 10, and a sliding cylinder 11.

[0006] The dust removal bags 7 are arranged and distributed inside the clean smoke chamber 1, the sealing boxes 9 are arranged on the upper and lower sides of the outer surfaces of both sides of the clean smoke chamber 1, the pulley 4 is fixed on one side of the sealing box 9, and the electric roller 2 is arranged in the middle of the outer surfaces of both sides of the clean smoke chamber 1.

[0007] The back-blowing air box 5 is connected to the back-blowing air cylinder 8 through a sliding cylinder 11 , and the steel cable 3 passes through the electric drum 2 , the pulley 4 , and the sealing box 9 in sequence. The steel cable 3 is connected to the traction trolley 6 through a connecting rod 10 .

[0008] Furthermore, there are four sealing boxes 9.

[0009] Furthermore, there are four pulleys 4.

[0010] Furthermore, there are two electric rollers 2.

[0011] Furthermore, the steel cable 3 has four sections.

[0012] Compared with the existing bag dust collector, the utility model has the following advantages.

[0013] The utility model provides a device for online replacement of the back-blowing traction cable of a horizontal bag dust collector. Compared with the traditional bag dust collector, four sealing boxes 9 are added. When replacing the steel cable 3, the steel cable 3 and the connecting rod 10 are pulled into the sealing box 9 by the electric roller 2. The maintenance personnel enter the sealing box 9 to disconnect the connection between the steel cable 3 and the connecting rod 10. The steel cable 3 can be replaced online without stopping the work, thereby effectively improving the working efficiency of the dust collector. BRIEF DESCRIPTION OF THE DRAWINGS
