Description

Technical Field

[0001] The utility model belongs to the technical field of wind collecting hoods, and in particular relates to a rainproof wind collecting and exhaust hood for a compressor. Background Art

[0002] Air compressors are basic products of industrial modernization and are the main body of the electromechanical air source device, the core equipment of the pneumatic system. In actual use, the compressor is generally installed indoors, so it is necessary to configure an air-collecting exhaust hood that leads to the outdoors for heat dissipation. The air-collecting exhaust hood structure currently used is mainly composed of an exhaust hood, a straight pipe, and an exhaust elbow. The exhaust elbow is a 90-degree elbow structure outdoors. Since the exhaust elbow is outdoors for a long time, when it rains, rainwater can easily enter from the port of the exhaust elbow and flow to the exhaust fan, affecting the performance of the exhaust fan. In order to solve this problem, a baffle is currently set on the inner wall at the lower part of the outlet end of the exhaust elbow. The rainwater entering from the outlet end of the exhaust elbow is blocked by the baffle and prevented from flowing into the air-collecting exhaust hood. However, the above-mentioned waterproof structure of the exhaust elbow still has the following problems during use: since the baffle is only provided on the inner wall at the lower part of the outlet end of the exhaust elbow, when it rains heavily, rainwater sometimes drifts into the side or upper part of the inner wall at the outlet end of the exhaust elbow, and then flows along the inner wall into the exhaust fan, so it cannot effectively play a rainproof role.

The utility model aims to improve the structure of the exhaust elbow so that it can effectively prevent rainwater from entering from the port and prevent flying birds and branches from entering, thereby avoiding unnecessary impact on the exhaust equipment.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A rainproof and wind-collecting exhaust hood for a compressor comprises an exhaust hood, a straight pipe and an exhaust elbow, wherein the upper end of the exhaust hood is fixedly connected to the lower end of the straight pipe, the upper end of the straight pipe is fixedly connected to the lower end of the exhaust elbow, the outlet end of the exhaust elbow is bent toward one side, a rainproof ring is provided on the circumference of the inner wall of the outlet end of the exhaust elbow to prevent rainwater from entering, the bending angle of the exhaust elbow is greater than 90° and the outlet end B is tilted downward by a degree to prevent water backflow, and a protective mesh is provided on the port of the outlet end of the exhaust elbow.
