Symmetric interchange structure circulation draught fan

Abstract

The invention discloses a symmetric interchange structure circulation draught fan, and belongs to ventilation equipment. The symmetric interchange structure circulation draught fan structurally comprises a circulation draught fan shell body, suction port end covers, an air outlet, a motor and draught fan blades. Connectors are symmetrically arranged at the left end and the right end of the circulation draught fan shell body. The suction port end covers and the motor are symmetrically arranged on the connectors on the two sides of the circulation draught fan shell body. The motor is connected with the circulation draught fan shell body through motor flanges and motor end covers, and a motor support is arranged at the lower portion of the motor. The symmetric interchange structure circulation draught fan has the beneficial effects that the left-and-right symmetric design of the circulation draught fan shell body is achieved, a suction port can be installed on the left side or the right side at will, the left suction or right suction circulation manner is achieved, the position of an air inlet can be adjusted according to actual situations, and the air inlet path can be adjusted; and seamless butt joint between the circulation draught fan and a ventilation port and other facilities is reliably achieved, the field installing problem can be solved, the field construction amount is reduced, the installing manner is flexible, and dismounting and maintaining are convenient.

Description

Technical field [0001] The invention relates to a ventilation device, in particular to a circulating fan with a symmetrical interchangeable structure suitable for occasions such as granary ventilation or circulation fumigation in the grain industry. Background technique [0002] Currently, there is no circulating fan product with a symmetrical interchangeable structure. The domestically standardized and mass-produced circulating fans are all left suction and the air outlet is close to the wall. Due to the interference influence and limitation of on-site installation space, equipment and other conditions, the left suction circulation fan cannot meet the on-site equipment installation requirements. To solve the change of the suction port direction, special designs such as mold opening are required. The equipment investment is large, the installation is difficult, and the site is beautiful. Poor sex. Circulating fans are widely used in the occasions of air volume transportation suc...

AI Technical Summary

Problems solved by technology

Due to the influence and limitation of on-site installation space, equipment and other conditions, the suction circulation fan on the left side cannot meet the needs of on-site equipment installation. In order to solve the direction conversion of the suction port, special design such as mold opening is required. The equipment investment is large, the installation is difficult, and the site is beautiful. poor sex

Circulating fans are widely used in grain depots, granaries and other occasions for air volume transportation. The prominence of this problem has gradually become a bottleneck in this industry, restricting the efficiency of ventilation; directly affecting the improvement of user benefits
