AI Technical Summary
Technical Problem
In the existing furnace head double-brush negative pressure vacuum cleaner system, the filter holes of the PTFE coated filter material are easily blocked by impurities, resulting in a degradation of filtration performance and difficulty in passing through the gas.
Method used
A negative pressure reverse pull-up double brush dust removal system is designed, and a dust removal mechanism is used to shake the connection frame by driving the connection to shake off the dust on the filter layer, reduce filter hole blockage and improve gas flowability.
Benefits of technology
It effectively reduces the unsmooth gas circulation caused by the filter hole blockage in the filter layer, extends the service life of the filter material, and improves the filtration efficiency of the system.

Abstract
The utility model provides a negative-pressure reverse-pumping double-brush dust discharging system which comprises a vacuum box arranged at one end of an air inlet pipe, a vacuum pump impeller arranged in the vacuum box, a filtering cabin arranged at the top of the vacuum box, a connecting frame arranged in the filtering cabin, a filtering layer arranged in the connecting frame, and a negative-pressure reverse-pumping double-brush dust discharging device arranged in the filtering cabin. A dust removing mechanism is arranged on the connecting frame and used for shaking off dust adhering to the filtering layer, the top of the filtering bin is connected with an air exhausting pipe, the dust removing mechanism comprises a fixing frame installed on the inner wall of the filtering bin, a transmission rod is inserted into the fixing frame, one end of a reset spring is connected with a limiting ring, and the inner ring of the limiting ring is connected with the outer side of the transmission rod. According to the negative-pressure reverse-pumping double-brush dust discharging system, dust adhering to the filtering layer falls off through shaking and falls into the collecting groove to be collected, and the problem that due to blockage of filtering holes of the filtering layer, gas circulation is not smooth is solved.
