AI Technical Summary

Problems solved by technology

When the dust collector is running, if the power of the off-line valve of this structure is cut off, the valve cover will drop to the flue gas outlet under the action of gravity to seal the flue gas outlet, and the flue gas in the upper box cannot pass through the flue gas. The outlet enters the cloth bag for filtration, and the dust collector cannot work normally
During maintenance, the flue gas that is continuously introduced gathers in the upper box, and the pressure increases. If the maintenance time is long, the flue gas that is introduced will cause serious damage to the dust collector

Embodiment Construction

[0011] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] As shown in the figure, an off-line valve of a bag filter includes a cylinder 1 set on the upper box 4 as a driving device. The cylinder 1 is provided with a connecting rod 2, and the connecting rod 3 passes through the shell wall of the upper box 4 and The end is connected with the valve cover 3 arranged at the smoke outlet 5 on the upper box body 4 , and the cylinder 1 drives the valve cover 3 through the connecting rod 2 to seal or open the smoke outlet 5 .

[0013] When the bag filter is running, the valve cover 3 is located below the flue gas outlet 5 of the upper box and is in an open state. The flue gas is filtered from the bag 6 and enters the flue gas outlet 5 through the upper box 4 before being discharged. When spraying, the cylinder 1 is started, the connecting rod 2 is connected with the valve cover...

Abstract

The invention discloses an off-line valve of a bag-type dust remover, comprising a driving device which is arranged on an upper case body; the driving device is provided with a connection rod which penetrates the shell wall of the upper case body; the end of the connection rod is connected to a valve cover which is arranged at a smoke exit on the upper case body; and the driving device drives the valve cover to close or open the smoke exit through the connection rod. When the power of the driving device is cut off, the valve cover ensures the smoke exit to open by the action of gravity, so that the dust remover is capable of running normally.

Description

technical field [0001] The invention relates to a bag filter, in particular to an off-line valve of the bag filter. Background technique [0002] The off-line valve of the bag filter includes a driving device and a valve cover connected with the driving device. When the bag filter is in normal operation, the valve cover of the offline valve needs to make the flue gas outlet of the upper box open, and the flue gas is filtered from the bag and enters the flue gas outlet through the upper box before being discharged. When spraying, the valve cover of the off-line valve needs to seal the flue gas outlet, and the spray pipe is used for spraying. [0003] The valve cover of the offline valve of the existing bag filter is arranged above the flue gas outlet inside the upper box. When the dust collector is running, if the power of the off-line valve of this structure is cut off, the valve cover will drop to the flue gas outlet under the action of gravity to seal the flue gas outlet...
