Embodiment 1

[0012] A water beam with thermal insulation sleeve for heating furnace, including anchor nail 1, water beam 2, pouring material 3, insulation sleeve 4 and fiber blanket 5, such as figure 1 As shown, the specific structure is: one end of the anchor nail 1 is welded and fixed on the outer surface of the water beam 2, the anchor nail 1 is used to fix the refractory material, the insulating sleeve 4 is woven by glass fiber, and the insulating sleeve 4 is set on the anchor nail 1. On the outer surface, the fiber blanket 5 is wrapped on the outer surface of the water beam 2, and the pouring material 3 is poured on the outer surface of the water beam 2 and wrapped with the insulating sleeve 4 and the anchor nail 1. The cross section of the anchor nail 1 is two line segments with a common end point, and the angle formed by the two line segments is 90°-150°, which is 120° in this embodiment.

[0013] In this embodiment, the insulating sleeve 4 is placed on the outer surface of the anch...

Abstract

The invention relates to the field of thermal insulation accessories for universal furnaces, kilns, baking furnaces or distillation furnaces, in particular to a water beam with a thermal insulating sleeve for a heating furnace. The water beam with the thermal insulating sleeve for the heating furnace comprises an anchoring nail (1), a water beam (2) and a castable (3), wherein one end of the anchoring nail (1) is fixedly welded on the outer side face of the water beam (2); and the castable (3) is cast on the outer surface of the water beam (2) and is used for wrapping the anchoring nail (1). The water beam is characterized by also comprising an insulating sleeve (4) and a fiber blanket (5), wherein the insulating sleeve (4) is formed by weaving fibers and is sleeved on the outer surface of the anchoring nail (1); and the fiber blanket (5) is wrapped on the outer side face of the water beam (2). The water beam makes construction convenient, has long service life due to the adoption of refractory materials, and has a good energy-saving effect.

Description

technical field [0001] The invention relates to the field of thermal insulation accessories for general furnaces, kilns, baking furnaces or distillation furnaces, in particular to a water beam with thermal insulation sleeves for heating furnaces. Background technique [0002] At present, two methods are commonly used to deal with the anchor nails in the water beam construction of the heating furnace: the first method is to brush a layer of asphalt oil on the surface of the anchor nails, and the second method is to wrap a layer of paper tape on the surface of the anchor nails. When the heating furnace is in normal operation, the high temperature in the heating furnace will volatilize the asphalt or incinerate the paper tape to form an isolation layer between the water beam of the steel pipe and the surface castable to reduce the oxidation speed of the anchor nail. These two methods are not ideal, and the life of the refractory material is only about one year. Contents of th...
