A segmented electric heating oven for drying polyacrylamide and its use method

Abstract

The invention relates to a segmented electric heating oven for drying polyacrylamide and its use method, and relates to the technical field of chemical equipment. The furnace seat and the furnace body are connected by a furnace bottom plate, and the first-stage heating zone, the second-stage heating zone and the third-stage heating zone There are heating tubes inside and installed in the furnace body from bottom to top. The heating tubes in each section of the heating zone are respectively controlled by the linkage control of the first-stage detection part, the second-stage detection part and the third-stage detection part; the feeding auger device is installed in the furnace One side of the furnace body; the external fan separator is horizontally installed on one side of the furnace body through flanges and gaskets, the external fan separator is located under the feeding auger device, the main stirring fan is erected outside the furnace body, and the output end of the main stirring fan rotates The blowing fan blade is connected, and the blowing fan blade is located in the furnace body and directly below the external fan separator. The invention has segmental heating, which can effectively control the temperature of the slow-sum stage before the material is released from the furnace, so that the drying effect of the material is better. advantage.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a segmented electric heating oven for drying polyacrylamide and a use method thereof. Background technique [0002] At present, the drying method of polyacrylamide is usually carried out by using a natural gas thermal oven, which was also well received by the manufacturer when the thermal oven was launched, but with the passage of application time, the following problems are more prominent: the drying heat is determined by the radiant heat of the burner Mainly, the temperature scale of radiant heat is unbalanced, which is improved by fan drive, but the middle of the oven basically relies on waste heat radiation, and the temperature of the material is not controlled in the slow recovery stage before being released from the oven. The overall thermal efficiency is relatively low compared to the calorific value of the fuel. It is difficult to improve; the air intake of the...
