Description
Technical Field
[0001] The utility model relates to the technical field of construction waste treatment equipment, in particular to a construction waste dust removal cyclone anti-blocking device. Background Art
[0002] In the dust removal process of the wind selection equipment in the current construction waste disposal process, a cyclone is needed to collect coarse and fine dust to prevent air pollution and damage to the environment. For example, an automatic cyclone dust collector disclosed in Chinese patent CN204841304U includes a dust collector body, an inlet pipe, a transparent observation hole, an outer vortex, an inner vortex, a cone, a cylinder, a controller, an upper vortex, an outlet pipe, an upper cover, and an ash hopper. The inlet pipe is arranged on the left side of the upper end of the cylinder, the transparent observation hole is arranged at the lower end of the inlet pipe, the cone is fixedly connected to the cylinder, the controller is arranged on the right side of the cylinder, the outlet pipe is arranged on the top of the cylinder, and the ash hopper is fixedly connected to the cone. In the above-mentioned prior art, after the sediment-containing gas enters the cylinder from the inlet pipe, it moves downward in a spiral along the inner side of the cylinder wall until it enters the ash hopper. The airflow is in a cyclic rotating state in the cylinder and then flows in the opposite direction to the top until it is discharged from the outlet pipe and enters the subsequent bag filter. During the rising process of the airflow, the coarse ash will be discharged from the ash hopper below, and some fine ash will enter the bag filter through the outlet pipe as the airflow rises, and is discharged after being filtered by the bag filter. The clean airflow after filtration is discharged into the atmosphere without causing environmental pollution. However, since the gravity of light matter is between coarse ash and fine ash, it can neither be discharged from the lower end of the ash hopper by gravity nor be brought into the bag filter with the rising airflow. It can only circulate and rotate in the ash hopper and be in a suspended state. After long-term operation, it will gather in large quantities and cause the ash hopper to be blocked, affecting the normal operation of the equipment. Utility Model Content

After the dust-containing gas carrying light materials enters from the air inlet of the cyclone 1, it moves downward in a spiral along the wall of the cyclone until it enters the dust box 2. At this time, the flap valve is in a closed state. The airflow in the dust box 2 is in a cyclic rotation state and then spirals upward in the opposite direction until it is discharged from the exhaust hole of the cyclone 1 and enters the bag dust collector.
