Abstract

The invention discloses a Raymond mill system capable of preventing dust accumulation of a fan. The fan, a Raymond mill, a cyclone separating discharging device and an air return air pipe form an air circulating milling discharging system. A pressure equalizing exhaust branch pipe is connected with the upper end of a cyclone pipe. A plurality of cyclones are arranged in the cyclone pipe. The lower end of the cyclone pipe is tangentially connected with a cyclone separator. A cyclone separating lower pipe opening is immersed in a circulating water pool, and the circulating water pool is connected with the upper end of the cyclone pipe. The fan impeller is provided with blades adopting a hollow and wedge-shaped structure. The external contour line of the fan is an involute. Low-resistance pressure equalizing exhaust is realized through arranging the cyclone pipe and the cyclones, and dust overflow caused by system positive pressure is eliminated. The circulating water pool realizes wet-process efficient dust removal and mineral powder recycling. As the blades adopt the hollow and wedge-shaped structure, dust on the induced draft fan impeller is cleared in real time, the impeller strength of the fan is increased, the stability is enhanced, and safety accidents caused by dust accumulation are effectively avoided. The application prospect is wide.

Description

technical field [0001] The invention relates to a Raymond mill system, in particular to a Raymond mill system in which fans do not accumulate dust. Background technique [0002] Raymond mill system is a kind of equipment widely used in ore crushing and grinding. Due to its strong adaptability and high cost performance, it has become the first choice for ore crushing and grinding. Raymond mill is an air flow internal circulation type powder output, due to the expansion of heated gas during the crushing process, if the ore has a high water content or water enters, not only will the output of the powder be reduced, but also a large amount of gas will be caused by the vaporization of the water. swell. Therefore, all Raymond mills are equipped with pressure equalizing exhaust branch pipes to input excess gas into the bag filter for purification and discharge, so as to avoid dust leakage caused by positive pressure in the crushing system, but when the humidity of the bag is high,...
