Dust removal and noise reduction device for grinding of internal surfaces of steel pipes

Abstract

A dust removal and noise reduction device for grinding of the internal surfaces of steel pipes comprises a dust remover and further comprises a noise and dust absorption barrel. The noise and dust absorption barrel comprises a barrel body, and the front portion of an inner hole of the barrel body is connected with a noise absorption plate. Absorption holes are formed in the noise absorption plate. The middle of the inner hole of the barrel body is connected with a partition plate. Noise absorption holes are formed in the partition plate. A dust removal hole is formed in the position, between the noise absorption plate and the partition plate, of the wall of the barrel body. A noise absorption body is arranged between the partition plate and a bottom plate of the barrel body. A rod protecting pipe is further arranged in the barrel body. The rod protecting pipe penetrates through the bottom plate of the barrel body, the noise absorption body, the partition plate and the noise absorption plate. The front end of the rod protecting pipe is connected with the noise absorption plate, and the rear end of the rod protecting pipe is connected with the bottom plate of the barrel body. One end of a dust removal pipe is connected to the dust removal hole in the wall of the barrel body, and the other end of the dust removal pipe is connected with the dust remover. The device has the following advantages of being novel in design, simple in structure, low in cost, convenient to use, capable of achieving the double functions of dust removal and noise reduction, good in dust removal and noise reduction effect, and capable of being enormously beneficial to a production environment and human health protection.

Description

technical field [0001] The invention relates to a dust-removing and noise-reducing device, in particular to a dust-removing and noise-reducing device for grinding the inner surface of a steel pipe. Background technique [0002] In the current steel pipe production process, since graphite, oxidized iron scale, etc. remain on the inner surface of the steel pipe, it must be ground off with a steel pipe inner surface grinding device, and the grinding head is a grinding wheel. The noise and dust are large during grinding, which seriously affects the environment and human health. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a steel pipe inner surface grinding dust removal device for noise reduction. It includes a sound-absorbing dust-absorbing barrel, the inner hole of the barrel is connected with a sound-absorbing board and a partition, the sound-absorbing board is provided with a suction ...
