AI Technical Summary

Technical Problem

In the mixing drums in the metallurgy and chemical industry, the stirring device is overheated due to the high solid content and high temperature of the slurry during the stirring process, causing problems such as lubricating oil emulsification and stirring over-temperature jumping, which affects the production progress, and high-temperature exhaust gas emerges from the observation hole, affecting the observation of the operator.

Method used

A cooling device for a stirring drum is designed, including a rotor assembly and a flow shield. Through the rotation of the driving wheel and the driven wheel, the exhaust wheel is driven to extract the exhaust gas in the stirring drum, and air is blown into the support drum through the flow shield to cool the stirring device.

Benefits of technology

It effectively avoids overheating of the stirring device, improves production progress, and through the design of the cooling device, the emergence of high temperature exhaust gas is reduced, and the observation conditions of the operator are improved.

Abstract

The utility model belongs to the technical field of mixing drums, and particularly relates to a cooling device of a mixing drum, which comprises the mixing drum and a mixing device arranged on the mixing drum, the mixing drum is provided with a feed inlet, the cooling device is arranged on the mixing drum and comprises a rotating wheel assembly and a flow guide cover, the flow guide cover is connected with the mixing device, and the rotating wheel assembly is connected with the flow guide cover. The rotating wheel assembly comprises a driving wheel and a driven wheel, the driving wheel is rotatably arranged in the feeding port, the driving wheel is connected with the driven wheel, the driven wheel extends into the flow guide cover, the driven wheel is driven to rotate through rotation of the driving wheel, and then air blowing cooling is conducted on the stirring device. Slurry enters from the feeding port and drives the driving wheel to rotate at the same time, the driving wheel rotates to drive the driven wheel and the exhaust wheel to rotate, the exhaust wheel pumps out exhaust gas in the stirring barrel, the situation that the temperature is too high due to too much exhaust gas in the stirring barrel is avoided, and the exhaust wheel rotates right opposite to the stirring device and blows air to cool the stirring device.
