Compact main machine structure of mining dry dust collector

The invention provides a compact main machine structure of a mine dry dust collector, which comprises a main box body, and an inlet air duct and an outlet air duct which are respectively arranged at two ends of the main box body, the interior of the main box body is divided into an upper-layer box body structure and a lower-layer box body structure, and a vertically arranged air duct partition plate is fixedly arranged in the upper-layer box body; the air duct partition plate divides the upper-layer box body into a dirty air duct and a clean air duct which are not communicated with each other, and a filter chamber is arranged in the lower-layer box body; an inlet of the dirty air duct communicates with the inlet air duct, an outlet of the dirty air duct communicates with the filter chamber inlet, an inlet of the clean air duct communicates with the filter chamber outlet, and an outlet of the clean air duct communicates with the outlet air duct. The main machine is compact in structure, reasonable in division
