Description

Technical Field

[0001] The utility model belongs to the technical field of industrial kilns, and particularly relates to an industrial kiln with a composite heat insulation structure. Background Art

[0002] An industrial kiln is a type of equipment used for high-temperature material processing, and is widely used in industries such as ceramics, building materials, metallurgy, and glass. Its main function is to heat raw materials to a specific temperature by burning fuel or using electrical energy to achieve processes such as sintering, melting, and drying. Industrial kilns have a significant impact on product quality in terms of temperature control, thermal efficiency, and production stability. The insulation mechanisms used in existing industrial kilns may age and crack after long-term use at high temperatures, reducing the insulation performance and affecting system safety. The conventional solution is to strengthen the regular inspection and maintenance of insulation materials, replace aging or damaged materials in a timely manner, and ensure insulation performance. However, the disadvantage of this method is that the replacement of insulation materials has a certain operational complexity, and regular maintenance and replacement of insulation materials will increase time costs and maintenance costs, thereby increasing operational complexity. Therefore, a new structure is proposed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide an industrial kiln with a composite heat insulation structure.

[0004] The utility model is realized by the following technical scheme: an industrial kiln with a composite heat insulation structure, comprising: a kiln body, a heat insulation mechanism and an installation cavity, wherein a group of installation cavities are respectively opened on the left and right sides of the front of the kiln body, and a group of heat insulation mechanisms are arranged inside each group of the installation cavities;

[0005] A set of slide grooves 1 are respectively opened at the top and bottom of the left side of the installation cavity, and two sets of slide grooves 2 are opened on the right side of the two sets of slide grooves 1. A set of fixed shafts are respectively fixed above and below the installation cavity, and a set of rotating lock plates are sleeved on the outer side of each set of fixed shafts;

[0006] The heat insulation mechanism consists of a heat insulation board 1, a heat insulation board 2 and a connecting plate. The heat insulation board 1 is injected with glycerin liquid, the heat insulation board 2 is filled with ceramic fiber, the heat insulation board 1 and the heat insulation board 2 are connected and fixed by two groups of connecting plates, the heat insulation board 1 is provided with a sliding bar 1 at the top and bottom, and the heat insulation board 2 is provided with a sliding bar 2 at the top and bottom.

[0007] As a preferred embodiment, the left and right sides of the kiln have the same structure and are arranged in mirror symmetry, a handle is installed in front of the insulation mechanism, a cavity is provided between the insulation board 1 and the insulation board 2, and the handle is filled with insulation cotton.

[0008] As a preferred embodiment, a liquid injection port is opened on the upper front side of the heat insulation board 1, the heat insulation board 1 and the two sets of slide bars 1 are an integrated structure, and the heat insulation board 1 is made of stainless steel.

The second heat insulation board is made of stainless steel. The length, width and height of the second heat insulation board are equal to the length, width and height of the first heat insulation board. In actual use, the side of the second heat insulation board close to the central axis of the kiln body is tightly fitted with the inner wall of the installation cavity, and the side of the first heat insulation board away from the central axis of the kiln body is tightly fitted with the main body of the installation cavity. When the kiln body is working, the ceramic fiber filled in the second heat insulation board has good thermal insulation performance, so it can protect the kiln. The furnace body is insulated for the first time, and the cavity between the second insulation board and the first insulation board is filled with air (two sets of connecting plates connect the first insulation board and the second insulation board, thereby forming a cavity between the first insulation board and the second insulation board). The air can delay the spread of heat, thereby playing the role of the second insulation. The glycerin liquid inside the first insulation board plays the role of the third insulation. Therefore, the triple insulation design can ensure the stability of the temperature inside the kiln body. The rotating lock plate is convenient for fixing the insulation mechanism inside the installation cavity, and it is also convenient for unlocking and removing the insulation mechanism.

[0011] As a preferred embodiment, the rotary lock plate is composed of a sleeve and two sets of baffles, the sleeve of the rotary lock plate is movably sleeved on the outside of the fixed shaft, and a limit block is provided on the front side of the fixed shaft.

[0012] As a preferred embodiment, the inner side of the sleeve is connected to the outer side of the fixed shaft by friction damping, and the distance between the two groups of baffles away from the sleeve is greater than the distance between the fixed shaft and the mounting cavity. In actual use, first rotate the four groups of rotating lock plates, rotate the four groups of rotating lock plates counterclockwise to a horizontal state, and then hold the handle to pull the insulation mechanism forward. At this time, the two groups of slide bars 1 slide forward along the two groups of slide grooves 1, and the two groups of slide bars 2 slide forward along the two groups of slide grooves 2 until the slide bar 1 is completely disengaged from the slide groove 1, and the slide bar 2 is completely disengaged from the slide groove 2, thereby completely removing the two groups of insulation mechanisms. The final effect is to facilitate the rapid disassembly of the insulation mechanism, thereby facilitating maintenance, saving maintenance time, improving maintenance efficiency, and simple operation.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by arranging the insulation board 1, the insulation board 2 and the cavity, the ceramic fiber inside the insulation board 2 can insulate the inside of the kiln body, the cavity prevents the insulation board 1 and the insulation board 2 from directly contacting each other, and the air inside the cavity has the effect of slowing down the heat transfer, and the glycerin liquid inside the insulation board 1 can be further insulated, thereby achieving the effect of triple insulation, and by arranging the slide bar 1, the slide bar 2, the slide groove 1, the slide groove 2 and the handle, the sliding connection between the slide bar 1 and the slide groove 1, and the sliding connection between the slide bar 2 and the slide groove 2, the insulation mechanism can be easily disassembled, ensuring that the insulation mechanism can be quickly disassembled, thereby simplifying the maintenance process, improving the maintenance efficiency, and being simple to operate.

When the kiln body 100 is working, the ceramic fiber 250 filled in the second heat insulation board 140 has good thermal insulation performance, so the kiln body 100 can be insulated for the first time. The cavity 260 between the second insulation board 140 and the first insulation board 130 is filled with air (two sets of connecting plates 180 connect the first insulation board 130 and the second insulation board 140, thereby forming a cavity 260 between the first insulation board 130 and the second insulation board 140).

In actual use, first rotate the four sets of rotating lock plates 190, rotate the four sets of rotating lock plates 190 counterclockwise to a horizontal state, and then hold the handle 120 to pull the insulation mechanism 110 forward. At this time, the two sets of slide bars 160 slide forward along the two sets of slide grooves 1 210, and the two sets of slide bars 2 170 slide forward along the two sets of slide grooves 220 until the slide bar 1 160 is completely disengaged from the slide groove 1 210, and the slide bar 2 170 is completely disengaged from the slide groove 220, thereby completely removing the two sets of insulation mechanisms 110. The final effect is that the insulation mechanism 110 is easy to quickly disassemble, thereby facilitating maintenance, saving maintenance time, improving maintenance efficiency, and simple operation.
