The invention belongs to the technical field of filter bags, and discloses a three-dimensional filter type high-strength uniform dust removal filter bag which comprises a gas guide assembly, a filter assembly is installed at the gas outlet end of the gas guide assembly, the gas guide assembly is used for inputting gas and dust needing to be filtered into the filter assembly, and the filter assembly is used for filtering the gas and the dust. The filter assembly is arranged in the shell, gas penetrates through the filter assembly to be discharged, dust remains on the surface of the filter assembly, an extrusion assembly is arranged in the filter assembly, and the extrusion assembly is used for scraping the inner wall of the filter assembly, so that the filter assembly continuously shrinks and expands, and the dust on the filter assembly falls off. The air exhauster works, so that the air exhauster exhausts air in the top cover, negative pressure is formed in the top cover, the efficiency of the air penetrating
