Problems solved by technology
Although the above-mentioned technology can automatically open and close the chimney cover of the boiler, there are also significant defects: after the chimney cover is opened, the chimney cover directly above the chimney will partially block the discharge of the smoke inside the chimney, limiting the discharge of the chimney. Smoke function, which in turn affects the combustion conditions of the boiler and reduces the combustion efficiency of the boiler

The invention discloses an automatic opening / closing device for a parallel-moving chimney cover. The device comprises the chimney cover, a lead screw, a guide rail, a sliding block, a U-shaped frame, a rolling nut, a coupling, a stepping motor, a motor rack, a rear rack and a rack board, wherein the U-shaped frame linearly runs together with the sliding block in the guide rail direction as the lead screw rotates, so as to drive the chimney cover to move in parallel; after the chimney cover is opened, the whole chimney cover is positioned at the right side of a boiler chimney, so that the poking and smoke exhausting functions of the chimney cannot be influenced. The device is simple in structure and convenient to operate, can improve the boiler combustion condition and increase the boiler combustion efficiency.
Description
technical field [0001] The invention mainly relates to the field of automation, in particular to an automatic opening and closing device for a chimney cover that can move in parallel, and is mainly used in steam injection boilers in heating stations and boilers in simplified configuration stations. Background technique [0002] Boiler operation management requirements: When the boiler equipment is in the "normal operation" state, the chimney of the boiler must be opened to discharge the flue gas; when the boiler equipment is in the "stop operation" state, the chimney of the boiler must be blocked to prevent external pollutants from entering Inside the boiler. Therefore, realizing the automatic "opening" and "encapsulation" of the boiler chimney is very important for the normal use of the boiler. [0003] In the traditional technology, when the boiler equipment stops running, the operator climbs to the top of the boiler and uses felts and ropes to block the chimney; A chimn...
