Sectional electric heating thermal oven for drying polyacrylamide and using method

Abstract

The invention relates to a sectional electric heating thermal oven for drying polyacrylamide and a using method, and relates to the technical field of chemical equipment. An oven base and an oven body are connected through an oven bottom plate, and heating pipes are arranged in a first-section heating area, a second-section heating area and a third-section heating area and installed in the oven body from bottom to top; the heating pipe in each section of heating area is controlled by a first-section detection piece, a second-section detection piece and a third-section detection piece respectively in a linkage manner; a feeding auger device is mounted on one side of the oven body; an external fan separator is horizontally installed on one side of the oven body through a flange and a gasket, the external fan separator is located below the feeding auger device, a main stirring fan is erected outside the oven body, the output end of the main stirring fan is rotationally connected with blowing fan blades, and the blowing fan blades are located in the oven body and located under the external fan separator. The sectional electric heating thermal oven for drying polyacrylamide has the advantages that sectional heating is conducted, the temperature of the tempering stage before materials are discharged from the oven can be effectively controlled, and thus the material drying effect is better.

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...
