Problems solved by technology

However, the microwave emission source of the microwave dryer in the prior art is above, the air humidity above the material is high during the drying process, and the microwave permeability is poor, which still limits the drying efficiency and effectiveness to a certain extent.

Abstract

The invention relates to a microwave dryer for polyacrylamide colloidal particles and a microwave drying method. The microwave dryer comprises a feed port, an induced draft fan, a conveyor and microwave emitting sources; the feed port is formed in the top of the microwave dryer; the induced draft fan is arranged on the side wall of the dryer near the feed port; a rotating valve is arranged in the feed port; a guide plate is arranged below the feed port; the front end of the conveyor is positioned below the guide plate; multiple stirring devices are arranged at the back end of the conveyor; and multiple microwave emitting sources are arranged below the conveyor. The microwave dryer is low in noise, fast in material drying speed, low in influence on materials by high temperature, excellent in production adaptability, suitable for drying of the polyacrylamide colloidal particles and suitable for drying of other high-viscosity polymers.

Description

technical field [0001] The invention belongs to the field of microwave drying, and in particular relates to a microwave dryer and a microwave drying method for polyacrylamide colloidal particles. Background technique [0002] Polyacrylamide generally contains more than 75% water before drying. It is a heat-sensitive material. The drying temperature is usually not higher than 90°C, and its viscosity is relatively high. Drying brings greater difficulty. At present, the fluidized bed drying method is often used in production. Fluidized bed drying, also known as boiling drying, is a method of drying granular solid materials using fluidization technology. In the fluidized bed, the particles are dispersed in the hot air flow, turned up and down, mixed and collided with each other to dry the material. Due to the high moisture content of polyacrylamide colloidal particles, it takes a relatively high wind speed to blow them up during the fluidized bed drying process and is relative...
