Problems solved by technology

[0004] Traditional vortex blowers are all made of aluminum alloy. Since the flow-passing parts are made of aluminum alloy and the support bearings are in contact with the gas medium, they are only suitable for conveying clean air and other non-corrosive gas media, and cannot be used for Transport all kinds of corrosive gas media, cannot transport gas media containing particles, etc., and cannot be used in flammable and explosive occasions; and casting defects such as pores, looseness, and cracks will occur during casting, which cannot be repaired by welding or other methods

Abstract

The invention relates to a vortex blower adopting the welding technology. The vortex blower comprises a vortex blower body, the vortex blower body comprises a machine shell and an impeller, the impeller is located in the machine shell, an impeller channel is arranged on the impeller, non-metal isolation rings in seal fit with the inner wall of the machine shell are arranged on the two sides of the impeller, the impeller is a welding impeller, and the machine shell is a welding machine shell; the advanced welding technology and the advanced machining method are utilized for manufacturing the complex impeller and the complex machine shell of the vortex blower, various metal materials with weldability can be selected as overflow component materials, and therefore compared with a traditional vortex blower, a brand-new structure and a brand-new arrangement manner are adopted in the vortex blower; and through reasonable selection and utilization of the materials, the vortex blower can be used for conveying various corrosive media, dust-contained media and high-temperature media, and also can be used for flammable and combustible occasions, and the application occasion and the application range of the vortex blower can be greatly expanded.

Description

technical field [0001] The invention belongs to the field of vortex blowers, and in particular relates to a vortex blower using a welding process. Background technique [0002] Vortex blower is a high-pressure blower, widely used in environmental protection industry, aquaculture industry, packaging machinery industry, printing machinery industry, plastic industry, chemical industry, food, pharmaceutical, medical, electronics, light industry and textile industry and other industries. [0003] The impeller of the vortex blower is composed of dozens of blades. The circulating airflow generated by the rotation of the impeller makes the air escape in the form of a spiral, so the air leaves with extremely high energy for use. The pressure it produces is 12-17 times that of a centrifugal fan with the same speed and diameter. [0004] Traditional vortex blowers are all made of aluminum alloy. Since the flow-passing parts are made of aluminum alloy and the support bearings are in co...
