Problems solved by technology

[0002] The existing axial flow fans need to change the site frequently when the industry and environment are different. In the process of changing the site, the possibility of collision and dumping of the fan is increased. When the fan cylinder is damaged, it will Cause the blades of the impeller to rub against or get stuck on the air duct, so that the fan cannot operate normally, and even cause damage to the fan

Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is further described:

[0011] As shown in the accompanying drawings, an impeller fan cylinder for an axial flow fan is provided with a fan cylinder 1, which is characterized in that an anti-collision ring 3 is provided on the outer wall of the fan cylinder 1 corresponding to the circumference of the impeller 2, and the two ends of the anti-collision ring 3 are respectively connected by a connecting ring 4 It is fixedly connected with the air cylinder 1, so that the anti-collision ring 3 and the connecting rings 4 at both ends form a groove structure, which strengthens the anti-collision strength of the surface of the air cylinder 1, and avoids the damage of the air cylinder 1 when the fan is collided or dumped The damage caused to the fan can achieve the effect of high protection performance.

[0012] When the present invention is produced, the steel plate can be bent to form a groove structure, that...

Abstract

The invention relates to the technical field of draught fans, in particular to an impeller air cylinder for an axial flow fan. The impeller air cylinder for the axial flow fan is provided with an air cylinder body, and is characterized in that the outer wall of the air cylinder body is provided with an anti-collision ring corresponding to the circumferential direction of an impeller, the two ends of the anti-collision ring are fixedly connected with the air cylinder body respectively through a connection ring, so that the anti-collision ring and the connection rings at the two ends form a groove type structure, the anti-collision strength of the surface of the air cylinder body is reinforced, and under the condition that the draught fan is collided and topples over, the damage to the draught fan due to the damage of the air cylinder body is avoided. Due to the structure, the impeller air cylinder for the axial flow fan has the advantages of being simple in structure, high in anti-collision strength, high in protective performance and the like.

Description

technical field [0001] The invention relates to the technical field of axial flow fans, in particular to an impeller fan cylinder for axial flow fans. Background technique [0002] The existing axial flow fans need to change the site frequently when the industry and environment are different. In the process of changing the site, the possibility of collision and dumping of the fan is increased. When the fan cylinder is damaged, it will As a result, the blades of the impeller rub against or get stuck with the air duct, so that the fan cannot operate normally, and even cause damage to the fan. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned deficiencies in the prior art, and provide an impeller fan cylinder for an axial flow fan with simple structure, high anti-collision strength and high protection performance. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005]...
