Description

Furnace wall anchoring device for unshaped refractory material

Technical Field

The utility model relates to an environmental protection field specifically is an unshaped refractory's brickwork anchor for among environmental protection equipment such as refuse power generation, incineration.

Background

In a boiler plant system, it is often necessary to have a large number of insulated furnace wall work surfaces to maintain the high temperature environmental requirements of the furnace, a region known as a refractory band. In the burning area, a large amount of unshaped refractory materials (refractory castable) are generally required to be laid on the surface of the water-cooled wall to prevent a part of boiler water-cooled wall from absorbing the radiant heat, so that the temperature of the burning area can be stabilized, and the stable combustion of fuel is facilitated; in the waste incineration boiler field, the sanitary combustion zone also has the functions of keeping the high-temperature environment of flue gas and decomposing dioxin, and can also reduce the abrasion of fuel to the water wall tubes in the area. The method specifically comprises the steps of fixing a certain anchoring piece in an area where refractory castable is required to be laid on a hearth water-cooled wall, and then pouring with the refractory castable.

In order to anchor the refractory castable, the prior art is to weld pins on the water wall pipes and weld Y-shaped grapples on the water wall ribs. The pins welded in advance in a factory are easy to damage and fall off in the process of equipment transportation and hoisting because the strength of the pins welded in high frequency is weak; the high-frequency welding machine used for welding the pins generally does not have the equipment on the spot, and the fallen pins are not allowed to be welded in situ again, and the fallen parts need to be subjected to close welding after being subjected to repair welding and flattening; and moreover, a hydraulic test needs to be carried out after the pins are welded on the water-cooled wall pipe, so that the pins are very troublesome to repair weld on the site of a construction site. In order to achieve the anchoring effect, pins with very close intervals are often arranged on the surface of the water wall, the number of the pins arranged per square meter is about 660, and the welding workload is very large. Considering the welding performance between the pin and the dissimilar steel of the water wall pipe, the pin is usually made of low alloy steel, the corrosion resistance and the high temperature resistance are poor in an extreme state, and the service life is limited. The traditional pin is of a straight cylindrical structure, so that the anchoring effect on the refractory castable is not good during anchoring, and the castable is easy to fall off during local use. Because the pin is rigidly connected with the water-cooled wall, and the coefficient of thermal expansion of the water-cooled wall and the casting material is greatly different, the thermal expansion of the pin and the casting material cannot be unified in a heated state, so that internal stress can be generated, and when the stress is too large, the pin welding point is torn, a large-area wall body falls off, or the surface of the casting material is torn, so that cracks are generated.

Therefore, how to provide an anchoring device which is convenient and fast to assemble and weld on site, can be used for a long time, has a good anchoring effect, can well protect unshaped refractory materials (refractory castable materials) from generating excessive internal stress in a hot running state, has a good anchoring effect, and urgently needs related professionals to solve the problem.
