Description

Technical Field

[0001] The utility model relates to the technical field of double - cyclone dust collectors, and particularly relates to a double - cyclone industrial dust collector. Background Technique

[0002] Industrial dust collectors are applied in industrial occasions such as dry cutting, welding, and grinding of brittle materials, where dust and particles are generated. The dust collector can inhale the gas containing industrial dust particles generated during the processing, treat it using methods such as filtration, adsorption, and separation, and discharge clean air at the outlet, so that the air quality of the operating environment meets the relevant industry standards and ensures the health of the operators. In existing dust collectors, when filtering the gas containing dust particles, a special filter element is usually used to intercept and adsorb the inhaled dust particles, or only by inertial force and the centrifugal force generated by high - speed rotation, the inhaled dust particles are made to impact the inner wall of the fixed outer shell and converge for collection.

[0003] The former has a poor filtering effect when the diameter and mass of the dust particles are large, and the filter element, as the only filtering device, will have a large working load due to long - term dust adhesion, which will further cause the performance of the dust collector to decline; the latter, although it has a non - consumable structure and low maintenance cost, has a low filtering efficiency, poor filtering accuracy, and when used for a long time, dust may adhere to the inner wall of the machine body, thus affecting the subsequent dust collection work. Based on this, this solution provides a double - cyclone industrial dust collector to solve the above - mentioned problems. Content of the Utility Model
