Description
Technical Field
The utility model relates to a dryer end cover, in particular to a dryer heat-preserving end cover.
Background
The paper industry equipment used to dry paper is typically a dryer. Steam or other heating media is introduced into the drying cylinder, heat is transferred through the cylinder wall, and paper on the outer wall of the drying cylinder is dried at high temperature. But the end cover surface of the drying cylinder is not a working surface, and a great amount of heat is wasted through radiation heat transfer and air convection. According to research and analysis, when the end cover of the drying cylinder does not take heat preservation measures, the waste heat accounts for 8% -11% of the total heat supply, so that the heat preservation and insulation measures are taken for the end cover of the drying cylinder, and the method has important meaning for reducing energy consumption and improving economic benefit. Meanwhile, the dryer end cover without heat preservation and insulation measures is extremely easy to cause human body scald due to high temperature, and threatens the personal safety of operators. Therefore, the adoption of heat preservation and insulation measures for the end cover of the drying cylinder becomes a necessary technology for the drying cylinder or the like.
Chinese patent CN2149417 discloses a "heat-insulating end cover for drying cylinder of paper machine", which is characterized by that between the sealing end cover and protecting plate of drying cylinder a composite heat-insulating layer is set, and the sealing end cover, composite heat-insulating layer and protecting plate are connected and fixed by means of bolts so as to form the heat-insulating end cover for drying cylinder. However, the technology has to drill a plurality of bolt holes for fixing connection on the dryer end cover in advance, so that the strength of the dryer end cover is reduced. For a drying cylinder which is put into use but does not take heat preservation and insulation measures, the necessary subsequent technical measures cannot be taken.
In addition, the technology considers the convenience of manufacturing the heat-insulating end cover, adopts the heat-insulating end cover to be manufactured into prefabricated parts, and then is spliced and installed on the end cover. However, in order to ensure the close fit between the heat insulation material and the end cover of the drying cylinder, the technology also adopts the method that bolt holes are drilled on the end cover of the drying cylinder, and the heat insulation material is fixed through tension bolts screwed on the end cover of the drying cylinder. Because the tightening bolt hole must be processed after the whole heat treatment of the drying cylinder, a large machine tool is required to process the drying cylinder, and the drying cylinder is time-consuming and labor-consuming and is extremely inconvenient. The number of the tightening bolt holes is large, and the tightening bolt holes are required to be completely opposite to the prefabricated mounting holes of the prefabricated member, so that great inconvenience is brought during mounting, and the prefabricated effect is greatly reduced.
