Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a refractory lining for a garbage incinerator. Background Art

[0002] A garbage incinerator is a device for incinerating and treating garbage. The garbage burns in the furnace and becomes waste gas that enters the secondary combustion chamber. It is completely burned under the forced combustion of the burner and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney. The garbage incinerator consists of four major systems: garbage pre-treatment system, incineration system, smoke biochemical dust removal system and gas generator (auxiliary ignition and incineration). It integrates automatic feeding, screening, drying, incineration, ash cleaning, dust removal and automatic control. A garbage incinerator is a harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. Its principle is to use the combustion of fuels such as coal, fuel oil and gas to burn and carbonize the objects to be treated at high temperature to achieve the purpose of disinfection. During the use of the incinerator, its interior is in a high temperature state. In order to ensure the normal use of the incinerator, a refractory lining is generally installed inside the incinerator in the prior art.

[0003] For example, the insulation layer refractory lining structure of an incinerator with publication number CN208846432U, the first insulation layer refractory lining structure of an incinerator includes andalusite brick layers, mullite brick layers and nano insulation boards arranged in sequence from the inside to the outside, and the nano insulation boards are fixed to the inner wall of the incinerator shell. The second insulation layer refractory lining structure of an incinerator includes a heavy castable layer, a light castable layer and a nano insulation board arranged in sequence from the inside to the outside, and the nano insulation board is fixed to the inner wall of the incinerator shell; the insulation layer refractory lining structure of the incinerator also includes insulation grabbing nails, which pass through the nano insulation board, the light castable layer and the heavy castable layer in sequence and then are anchored. The beneficial effects of the utility model are: the overall thickness is thin and space is saved, which correspondingly reduces the size of the incinerator shell, saves the production and processing costs and installation space of the incinerator shell; the overall compressive performance is improved to avoid deformation or even collapse, thereby ensuring that the incinerator has a long service life and low maintenance costs.

[0004] The above technical solution has some problems in practical application. When the lining in the incinerator is partially damaged, it is inconvenient to replace it. In addition, the lining of the incinerator is prone to thermal expansion and contraction when affected by high temperature, resulting in cracking and damage, which affects its service life.

[0005] Therefore, it is necessary to invent a refractory lining for a garbage incinerator to solve the above problems. Utility Model Content

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model provides a plurality of refractory bricks, which are connected end to end to form an incinerator lining structure.

When the lining is partially damaged, it is convenient to quickly replace the damaged part. A cavity is provided inside the refractory brick, and a movable block that can slide horizontally is provided on one side of the cavity. When the refractory brick is affected by the incinerator and the temperature rises rapidly, the air in the cavity expands due to heat and pushes the movable block outward to offset the heat, thereby avoiding the refractory brick from cracking due to thermal expansion, thereby effectively improving the service life of the incinerator lining.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0022] Specifically, a cavity 6 is provided inside the refractory brick 1, and a plurality of heat-conducting blocks 7 are fixedly provided inside the cavity 6, and the heat-conducting blocks 7 are arranged in a "Z"-shaped structure. Two through grooves 8 are provided through one side of the cavity 6, and a movable block 9 is provided through the through groove 8.

A limit block 10 is fixedly provided at one end of the movable block 9, and the limit block 10 is arranged inside the cavity 6. The setting of the limit block 10 can prevent the movable block 9 from being separated from the through groove 8, thereby facilitating the transportation and installation of the refractory brick 1.

[0023] More specifically, a plurality of heat-conducting grooves 12 are provided on the inner side of the refractory brick 1, and the heat-conducting grooves 12 are arranged in a square structure, and the notches of the heat-conducting grooves 12 are provided with rounded corners, and the setting of the rounded corners can prevent the materials in the incinerator from staying in the heat-conducting grooves 12;

[0024] In addition, a plurality of extension grooves 13 are provided on the outer side of the refractory brick 1, and the plurality of extension grooves 13 are arranged at equal intervals. The extension grooves 13 are arranged in a trapezoidal structure. The setting of the trapezoidal structure increases the contact area between the extension grooves 13 and the cement mortar, thereby increasing the installation strength of the refractory brick 1.

[0025] In summary, a plurality of refractory bricks 1 are spliced ​​inside the incinerator to form the lining of the incinerator. When the plurality of refractory bricks 1 are spliced, the refractory bricks 1 are bonded to the inner wall of the incinerator by cement mortar, and two refractory bricks 1 are spliced ​​in sequence. During this process, the first connecting block 2 on one refractory brick 1 and the second connecting block 3 on the other refractory brick 1 are spliced ​​with each other, and the positioning block 5 is inserted into the groove 4. At this time, the splicing of the two refractory bricks 1 can be realized, and the movable block 9 on one refractory brick 1 corresponds to the slot 11 on the other refractory brick.

[0026] During the use of the refractory brick 1, the hot air in the incinerator transfers heat to the cavity 6 by heat transfer, causing the air in the cavity 6 to expand. After the air expands, the movable block 9 is pushed outward. During the expansion process, the air can offset the heat of the refractory brick 1, thereby preventing the refractory brick 1 from cracking due to thermal expansion.
