The fan is easy to disassemble the Raymond mill device

Abstract

The invention discloses a Raymond mill device with a convenient-to-disassemble fan. The fan, a Raymond mill, a cyclone separation discharger and a return air pipe form an airflow circulating milling discharging system, a pressure-equalizing exhausting branched pipe is connected with the upper end of a cyclone pipe, multiple cyclone separators are arranged in the cyclone pipe, the lower end of the cyclone pipe is tangentially connected with the cyclone separation discharger, the cyclone separation discharger discharges purified air and immerses below liquid level of a circulating water pool which is connected with the upper end of the cyclone pipe, blades of an induced draft fan impeller are arranged radially in a manner than the impeller is in axial, radial and central symmetry, and centrifugal force can be utilized to timely clean dust to avoid safety accidents. The Raymond mill device is less prone to causing mineral powder dust leakage, disassembling and assembling technology of an induced draft fan is improved substantially, pressure applied on screw shaft shoulder end faces by nut parts can be eliminated simply during disassembling of the fan, and the problem that the induced draft fan which is in threaded assembly constantly locks automatically and is difficult to disassemble under load action is solved effectively. The Raymond mill device is especially suitable for and has particularly remarkable effect on convenient and quick disassembling of large fans after being locked in a threaded manner.

Description

technical field [0001] The invention relates to a Raymond mill device, specifically referring to a Raymond mill device in which the fan does not accumulate dust and is easy to disassemble and overhaul. Background technique [0002] Raymond mill 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 sy...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
