Anti-CO poisoning rotary chimney head based on flow rate differential pressure

Abstract

The invention discloses a CO poisoning prevention rotary chimney head based on flow velocity differential pressure. The rotary chimney head comprises a top cover, wherein the lower end of the top cover is fixed with extension ends of the upper end of a main cylinder; a ventilation duct is welded between extension ends of the main cylinder; supporting plates are welded at the lower end of the ventilation duct; the supporting plates are in the shape of a right triangle; two right-angle sides are respectively welded on the ventilation duct and the outer wall of the main cylinder; the lower end of the main cylinder penetrates through an upper fixing disc; the outer side of the cylinder body is connected to a bearing inner ring, then penetrates through a lower fixing disc and sleeves at a clamping groove of a mounting cylinder; a bearing is arranged on the upper fixing disc in a sleeving manner, and an outer ring is clamped at the clamping groove in the upper end of the lower fixing disc; and the upper fixing disc is detachably connected with the lower fixing disc. Due to the bearing, the whole chimney head freely rotates in different wind directions under the action of the supporting plates, so that the wind passes through the ventilation duct to absorb the smoke under the action of different flow velocities, and finally, unburned CO is discharged through the main cylinder so as to prevent CO poisoning. The rotary chimney head disclosed by the invention has the advantages of being low in construction cost, simple in principle structure, low in environmental requirement and excellent in operating effect.

Description

Technical field: [0001] The invention belongs to the technical field of outdoor safety mechanical chimney heads, and in particular relates to a CO poisoning-proof rotating chimney head based on flow velocity differential pressure. Background technique: [0002] At present, there is poor exhaust effect in household CO and other gas fields, or it is difficult to prevent the effect of CO in some ordinary outdoor chimney heads, which may easily cause indoor air flow and cause life and property threats. For the emission of CO due to incomplete combustion of fuel. Existing chimney heads have little effect on this problem, and have disadvantages such as single function, no function of preventing CO poisoning, and poor rainproof performance. Invention content: [0003] The purpose of the present invention is to overcome the problems existing in the prior art, and to provide a CO poisoning prevention rotary chimney head based on flow velocity differential pressure. [0004] In or...
