Refractory material hanging plate capable of being rapidly replaced for garbage incinerator

Abstract

The utility model belongs to the technical field of refractory materials, and relates to a refractory material hanging plate for a garbage incinerator. The refractory material hanging plate is provided with a through hole structure used for installing a pin. The four side edges of the hanging plate are parallel in pairs and are planes so that the hanging plate can enter and be taken out in the vertical direction of the water cooling wall during installation. The through hole is positioned between the two arc-shaped grooves; the through hole penetrates through the whole thickness direction of the hanging plate and is an inner-layer step-shaped through hole and an outer-layer step-shaped through hole, and the size of the through hole of the instant heating surface is larger than that of the through hole of the cold surface; according to the application mode of the through holes, pins on the water cooling wall penetrate through the small-size through holes in the cold face of the hanging plate and are matched with nuts in the large-size through holes in the hot face of the hanging plate to fasten the hanging plate to the water cooling wall. And the pin and the nut are both lower than the hot surface of the hanging plate, so that the through hole is filled with a refractory filler and can be covered after the installation is finished. According to the utility model, the local or single hanging plate can be quickly replaced after the hanging plate of the water-cooled wall is damaged, and other hanging plates around are not dismounted or damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of refractory materials, and particularly relates to a refractory material hanging plate for a waste incinerator that can be quickly replaced. Background Art

[0002] Waste incineration power generation is the most effective way to realize the harmlessness, reduction, resource utilization and sustainable development of waste, and it is the most widely used method for efficient and clean treatment of waste in countries around the world at present; the refractory lining material in the waste incinerator not only protects the main metal structure (especially the water-cooled metal pipe wall) from being eroded and damaged by the internal atmosphere environment at high temperature, but also plays a key role in guiding the waste heat generated by waste incineration for power generation; compared with the unshaped materials of the same material, the hanging plate belongs to a shaped product, which is superior in terms of bulk density, strength, thermal conductivity, erosion resistance, etc., has a longer service life, and is easier to install; with the extension of the application years, the hanging plate for the waste incinerator is affected by the application environment atmosphere such as erosion and thermal shock, and local damage or falling off may occur, which needs to be repaired in time; at present, due to the influence of its hanging opening, hanging nail structure and side structure, the hanging plate cannot be replaced and repaired with a hanging plate of the same structural shape after it falls off, and only unshaped materials can be used for repair, which affects the use effect. Summary of the Utility Model

[0003] In order to realize the quick replacement of a single piece or a part of the hanging plate of the waste incinerator, the purpose of the utility model is to provide a refractory material hanging plate for a waste incinerator that can be quickly replaced.

[0004] The utility model adopts the following technical solutions to achieve the above purpose:

[0005] A refractory material hanging plate for a waste incinerator that can be quickly replaced, the refractory material hanging plate has a through-hole structure for installing a pin; the body of the refractory material hanging plate is such that two of the four side edges are parallel to each other and are all flat surfaces so that it can enter and be taken out along the vertical direction of the water-cooled wall during installation; the cold surface of the body of the refractory material hanging plate has an arc-shaped groove that matches the water-cooled pipe on the water-cooled wall, and there is a through-hole for installing a pin between two adjacent arc-shaped grooves; the through-hole penetrates through the entire thickness direction of the hanging plate and is a stepped through-hole; the through-hole near the hot surface is a large-size through-hole, and the through-hole near the cold surface is a small-size through-hole; the pin passes through the small-size through-hole and cooperates with a nut in the large-size through-hole to fix the hanging plate on the water-cooled wall.

[0006] The shape of the through-hole is circular, oval, square or a combination of any two.

[0007] A refractory material hanging plate for a waste incinerator that can achieve rapid replacement proposed by the present utility model. The hanging plate is a dense body. The hanging plate is close to the metal water wall, and there is only a very thin layer of unshaped refractory material between the two. There are through holes penetrating the thickness of the hanging brick between the arc-shaped grooves on the hanging brick, and the size on the hot surface side is larger than that on the cold surface side. The connection between the hanging plate and the water wall is achieved by passing the pins welded on the fins (flat steel) between the water cooling pipes through the small through holes on the hanging brick and matching with the nuts in the large-sized through holes to fasten the hanging plate on the water wall. The studs and nuts are both lower than the hot surface of the hanging plate. After the above steps are completed, the through holes are sealed with unshaped materials and the pins and nuts are covered. The advantage of this utility model is that when a local or single hanging plate falls or is damaged, the hanging plate of this utility model can be directly replaced and installed without removing the other surrounding hanging plates.

[0013] The present utility model will be described in conjunction with the accompanying drawings and specific embodiments:

[0014] As Figures 1-6 shown, a refractory material hanging plate for a waste incinerator that can achieve rapid replacement. The body 1 is a dense body. Its cold surface has arc-shaped grooves that match the water cooling pipes of the water wall. There are circular, square or oval through holes 3 between the arc-shaped grooves, penetrating to the hot surface of the hanging plate. The size of the through holes on the cold surface is smaller than that on the hot surface, and a step is formed inside the hanging plate. When installing the hanging plate, the pins 2 on the fins between the water cooling pipes pass through the small through holes on the cold surface of the hanging plate to reach the large through holes, and are matched with the nuts in the large through holes to fasten the hanging plate and the water wall from the large through holes. Subsequently, the through holes are sealed with unshaped materials and the pins and nuts are covered. The hanging plate of this utility model can be independently installed and quickly replace the damaged hanging plate without removing the other surrounding hanging plates.
