Dust cleaning device for belt conveyor belt surface

Abstract

The invention relates to a dust cleaning device for a belt conveyor belt surface. The dust cleaning device is characterized by mainly comprising a dust collection hood, a dust blowing device and a negative pressure dust collection device, wherein the dust collection hood is installed below a conveyor belt at the discharge end of a belt conveyor, spring telescopic rods are installed between the dust collection hood and a supporting part, the upper end of the dust collection hood is connected with the dust blowing device in the direction of the cross section of the belt, a conical dust collection chamber is arranged at the lower end of the dust collection hood, the dust collection chamber is connected with the negative pressure dust collection device, and the amount of negative pressure of the negative pressure dust collection device is larger than the discharge of compressed air of the dust blowing device. Positive pressure is provided by the compressed air to blow off dust adhering to the belt or a part in a belt crack, dust is then absorbed through the negative pressure, accordingly, air under positive pressure and negative pressure is adopted as power to blow the dust away from the belt, the dust is blown off more thoroughly, and no dead angle is left during dust blowing; meanwhile, the spring telescopic rods can maintain good sealing performance between the dust collection hood and the belt, so that the dust collection effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of dust cleaning on the belt surface of a belt conveyor, in particular to a dust cleaning device on the belt surface of a belt conveyor. Background technique [0002] The dust collector technology is constantly improving, and the dust collection efficiency is higher, but there are still some dust collection blind spots, such as the problem of belt dust, because the dust is mixed in the gap of the belt, the dust collection duct does not work at all for this part of the dust, and the belt is After turning the head roller, the dust in the gaps is scattered to the ground, forming fugitive discharge and causing pollution. In order to reduce dust emissions and prolong the service life of the belt, after several months of on-site observation and analysis, we have a detailed understanding of the causes of belt dust and existing measures, and put forward new solutions. The specific content is as follows: [0003] Th...

AI Technical Summary

Problems solved by technology

[0005] But the cleaning effect is not good. The reason is that the cleaner can only clean the dust on the surface of the belt, and cannot clean the dust mixed in the gaps of the belt. In addition, the rubber on the cleaner is often worn unevenly, resulting in high sides on both sides and bottom in the middle. Most of them are transported by the middle part of the belt, which loses the function of the cleaner and is not easy to find
