Description

Technical Field

[0001] The utility model belongs to the technical field of industrial dust removal and relates to self-cleaning industrial dust removal equipment. Background Art

[0002] Industrial dust removal equipment, which separates industrial dust from flue gas, is called an industrial dust collector or industrial dust removal equipment. In existing industrial vacuum cleaners, dust often accumulates on the filter due to the use of time, resulting in poor dust collection effect.

[0003] However, the back-blowing cover used to cover the back-blowing hole in the prior art has a complex structure and is inconvenient to operate. The existing technology for cleaning the filter screen generally solves the problem of dust accumulation by disassembling and assembling the filter screen. Such methods are generally cumbersome and easily cause damage to the back-blowing device on the upper cover of the vacuum cleaner. Therefore, a method that can release air pressure to solve the problem of dust accumulation is needed. At the same time, the existing back-blowing device cannot release air pressure for a long time, otherwise the dust will not be cleaned in time.

[0004] Reference document CN201120104273.2 describes an industrial high-negative-pressure vacuum cleaner. This vacuum is generated by activating a fan to draw air outwards, and by intermittently opening a pulse solenoid valve on a short pipe, which allows the short pipe to flow through. This allows outside air to be blown into the vacuum cleaner's cylinder using the negative pressure within it, causing dust adsorbed on the filter element to fall into an ash bin below the vacuum cleaner's cylinder. This eliminates the need for an external high-pressure air source to clean the filter element.

[0005] First, the prior art uses a negative pressure environment, followed by a sudden influx of air, to remove dust. This reference requires multiple valves for opening and closing. Because the sudden opening and closing of the negative pressure environment creates a sudden change in pressure, the valves must withstand high pressure. The mechanical transmission of this application, however, achieves excellent pressure conversion.

[0006] In summary, the present invention provides a self-cleaning industrial dust removal device. Utility Model Content

[0025] Beneficial effects
