In the working process of many industrial production workshops, a large amount of dust and waste gas will be generated. These dust and waste gas are usually suspended in the air. The dust concentration in some places is very high, which seriously affects the production and working environment, and also affects the production line. The body of the staff brings great harm, and may even induce a variety of diseases; and the exchange of air with dust and waste gas with the outside atmosphere will also cause pollution to the outside atmosphere and the surrounding environment.  

A dust collector is a device used for industrial purposes to collect and absorb waste medium particles, dust and smoke generated in the production process. In the actual collection of dust or waste gas, a device that generates smoke and dust, such as a semi-continuous casting furnace, which is smelting During the process, it needs to move back and forth within a certain distance, so the dust collector is required to have the function of moving synchronously with the semi-continuous casting furnace, so as to better collect smoke and dust.

In this regard, based on years of research experience, our company has developed a telescopic connection pipe used in the dust collector.

This utility model will be patented on October 29, 2021, and the patentee is Ningbo Changqing Environmental Protection Technology Co., Ltd. The product is realized by the following technical measures: a telescopic connecting pipe used in a dust collector, including a telescopic pipe coupling, one end of the telescopic pipe coupling is connected with the furnace dust discharge pipe, and the other end is connected with the telescopic pipe assembly The other end of the telescopic tube assembly is connected to a square tube, wherein the telescopic tube assembly is formed by sleeved joints of several telescopic tubes, the diameter of each telescopic tube increases in turn, and the small-diameter telescopic tube is sleeved into a larger one. In the No. 1 telescopic pipe, one end of the telescopic pipe is provided with a flange plate, and a steel wire rope is arranged on the flange plate, and the steel wire rope connects two adjacent telescopic pipes.

Compared with the prior art, the advantage of the present utility model lies in that: by setting up a multi-section telescopic pipe, the small-diameter telescopic pipe is sleeved into a larger telescopic pipe to form a telescopic pipe assembly, and the telescopic pipe assembly is realized. When stretching or shrinking, so that the furnace that generates smoke and dust moves back and forth within a certain distance, the dust collector with the telescopic tube assembly can also move synchronously with the semi-continuous casting furnace, so as to better collect the smoke and dust.
