A simple Raymond mill device that is easy to disassemble the fan

Abstract

The invention discloses a simple Raymond mill device with a fan convenient to disassemble. The fan, a Raymond mill, a cyclone separating and discharging device and an air return duct form an air-flow-circulating ground-powder discharging system. An isolating temporary storage barrel is arranged at an inlet, connected with the air return duct, of the fan. A gravity material door is arranged on the isolating temporary storage barrel. A temporary powder storage barrel is arranged below the gravity material door. A valve and a discharging gate are arranged on the temporary powder storage barrel. Blades of an impeller of the induced draft fan are arranged symmetrical about the center of an impeller shaft in the radial direction in a radial manner, dust can be cleared up in time through centrifugal force, and safety accidents are avoided. The simple Raymond mill device is simple in structure, and more importantly, the disassembly technology of the induced draft fan is improved greatly, so that pressure applied to the shaft shoulder end face of a screw by components similar to a nut component can be eliminated easily when the induced draft fan is disassembled, and the problem that the induced draft fan is locked continuously and automatically and cannot be disassembled easily under the load action due to threaded assembly is solved effectively; and the simple Raymond mill device is especially suitable for convenient and fast disassembly of the large-scale fan which is locked in a threaded manner, and the effect is especially remarkable.

Description

technical field [0001] The invention relates to a Raymond mill device, specifically a simple 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. The fan is the key equipment of the Raymond mill. The induced draft fan is generally a centrifugal fan. The continuous, stable and reliable operation of the induced draft fan is very important for the Raymond mill. Because most of the places where the Raymond mill is used contain a certain amount of dust, the induced When the fan is working, when the airflow passes through the high-speed rotating fan impeller, due to the centrifugal separation, the dust particles will separate from the airflow phase and deposit on the fan impeller. [0003] The impeller spee...

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
