Connecting device convenient for disassembling and assembling jetting pipe

Technical Field

The utility model belongs to the technical field of dust removal equipment, and particularly relates to a connecting device convenient for disassembling and assembling a blowing pipe.

Background

The pulse bag dust collector is a common industrial dust collection device and is mainly used for treating industrial waste gas and dust. At present, the pulse bag dust collector is widely applied at home and abroad, and particularly is commonly used in the industries of steel, cement, chemical industry, electric power and the like. Along with the improvement of environmental awareness and the continuous enhancement of environmental protection policies, the market demand of the pulse bag-type dust collector is also increasing. Meanwhile, along with the continuous progress of technology, the technology of the pulse bag-type dust collector is also continuously improved and upgraded, for example, a more efficient filter bag material, a more advanced control system and the like are adopted, so that the pulse bag-type dust collector is more energy-saving, efficient and stable. In general, the pulse bag dust collector has wide application prospect in the industrial field and has great development space in the future.

The jetting pipe of the pulse bag-type dust collector is an important component in the dust collector, and the main function of the jetting pipe is to jet high-pressure air into the bag so that the bag bulges, dust particles attached to the outer surface of the bag are separated from the surface of the bag and deposited in the ash bucket, thereby achieving the purpose of dust collection. The principle of the blowing pipe is that compressed air is utilized to quickly jet the air in the blowing pipe into the cloth bag to form instant air flow, so that dust particles outside the cloth bag are impacted, and are separated from the surface of the cloth bag and fall into an ash bucket at the bottom of the cloth bag dust collector, and the aim of dust removal is fulfilled. The number and layout positions of the blowing pipes of the pulse bag dust collector have great influence on the dust collection effect, and special design and adjustment are generally required according to the specific situation of the dust collector.

The connecting device of the jetting pipe of the pulse bag-type dust collector is generally in threaded connection or flange connection. The threaded connection is simple and convenient, but the tightness is poor, and the air leakage phenomenon is easy to occur; the flange connection has good tightness, but is complex to install, and special tools are needed. At present, a clamp type connecting mode is also used in related researches, the installation is more convenient and faster than flange connection, but the clamp type connecting mode still needs to be fixed by bolts and nuts, is inconvenient to install, and is easy to generate phenomena such as air leakage.
