[0002] The household garbage incineration waste heat boiler is a kind of equipment specially designed for processing municipal solid waste and generating steam or hot water through incineration process, which can not only effectively reduce the amount of garbage, but also recycle energy generated during incineration process to realize resource recycling.

[0003] In the household garbage incineration waste heat boiler, the sealing support generally adopts the form of internal heat insulation, that is, a square box is welded by steel plate at the place where the membrane water cooling wall needs to be holed, and refractory castable or combined insulation castable is poured inside to realize sealing, wear protection and corrosion protection. However, although this design solves the problem of internal high temperature protection, it fails to effectively handle the overtemperature phenomenon of the outer surface. Even in the case of good on-site construction quality, the temperature of the outer surface of the sealing support often exceeds 60℃, and in the case of poor construction quality, the temperature may even exceed 120℃, forming a significant heat sink and a dangerous area, which not only leads to unnecessary heat loss and increases the temperature burden of the entire indoor environment, but also poses a serious risk of scalding to the operators, especially in frequent contact areas such as test holes and manhole doors, the safety hazards are particularly prominent.

[0004] Therefore, the sealing support design in the prior art has obvious deficiencies in ensuring operation safety and reducing environmental temperature, and needs to be improved to ensure better heat insulation effect and higher safety. UTILITY MODEL CONTENTS

[0027] The several core-pulling rivets 3 are used for fixing the outer protective plate 2 and the corrugated protective layer of the waste incineration waste heat boiler surface.

[0028] The several fixing members are used for fixing the heat preservation blanket 1 on the sealing support of the waste incineration waste heat boiler, the fixing member comprises a sleeve 4, the bottom end of the sleeve 4 is fixedly connected to the sealing support of the waste incineration waste heat boiler, the sleeve 4 is welded on the sealing support, the stability of installation is guaranteed, meanwhile, the sleeve 4 will not cause abrasion to the surface of the waste incineration waste heat boiler, the inside of the sleeve 4 is threadedly connected with a connecting piece 6, the connecting piece 6 is in a cylindrical structure, the bottom end of the connecting piece 6 is in a conical structure, the top end of the connecting piece 6 is fixedly connected with a spring 7, the spring 7 is arranged above a pressing ring 5, the pressing ring 5 is coaxially arranged with the connecting piece 6, the inner ring of the pressing ring 5 is fixedly connected with several connecting frames 8, the connecting frames 8 are in a horizontal U-shaped structure, the end of the spring 7, away from the connecting piece 6, is fixedly connected with the pressing ring 5 through the connecting frames 8, the top of the connecting piece 6 is provided with a mounting hole 12 matched with a mounting tool, so that a worker can use a screwdriver or other tools to screw the connecting piece 6, and the fixing of the connecting piece 6 and the sleeve 4 is realized, further, after the installation of the pressing ring 5 is completed, the core-pulling rivets 3 are used for fixing the outer protective plate 2 and the edge position on the surface of the pressing ring 5, so that the stability of the overall structure of the device can be improved.

[0029] Further, the lower surface edge position of the pressing ring 5 is fixedly connected with several limiting frames 9 in an L-shaped structure, the limiting frames 9 are arranged in a circumferential array, the limiting frames 9 are jointly provided with a connecting ring 10, the upper surface of the connecting ring 10 is rotatably connected with the lower surface of the pressing ring 5, the connecting ring 10 is coaxially arranged with the pressing ring 5, the outer ring of the connecting ring 10 is rotatably connected with the inner side of the limiting frame 9, the longitudinal section of the connecting ring 10 is in a T-shaped structure, the lower surface of the connecting ring 10 is lower than the bottom of the limiting frame 9, so that the lower surface of the connecting ring 10 will be in contact with the heat preservation blanket 1 during installation, and the rotating limiting frame 9 is not in contact with the heat preservation blanket 1, the lower surface of the connecting ring 10 is fixedly connected with several inserting rods 11, the inserting rods 11 are distributed in a circumferential array, the inserting rods 11 play a limiting role in the horizontal direction of the heat preservation blanket 1, and the stability of the position of the heat preservation blanket 1 is achieved.

[0030] The specific working principle of the utility model is as follows:

[0031] When installing, the worker uses a welding tool to weld a plurality of sleeves 4 to the surface of the incineration waste heat boiler sealing support, and a hole corresponding to the sleeve 4 is reserved on the surface of the thermal blanket 1, or the thermal blanket 1 is directly penetrated by the conical bottom end of the connecting piece 6 during installation. When the hole is reserved, the connecting piece 6 is aligned with the hole, and a screwdriver is sequentially inserted through the compression ring 5, the connecting ring 10, and the spring 7 so that it can be connected with the installation hole 12. Then, the connecting piece 6 is screwed, and the connecting piece 6 moves to the inside of the sleeve 4 while rotating, and the compression ring 5 and the connecting ring 10 move in the same way.

This design can separate the thermal blanket 1 from the rotating compression ring 5, on the one hand to ensure the smooth installation of the compression ring 5, and on the other hand to prevent the compression ring 5 from causing wear to the thermal blanket 1, and at the same time, the insertion rod 11 can also be smoothly inserted into the thermal blanket 1. When the installation of the connecting piece 6 is completed, the compression ring 5 will exert pressure on the connecting ring 10 and the thermal blanket 1 under the action of the spring 7, thereby fixing the thermal blanket 1. This design enables the device to fix thermal blankets 1 of different thicknesses, improves the applicability and flexibility of the device, and enables the thermal blanket 1 to be in contact with the sealing support at all times, thereby ensuring the heat insulation performance of the device on the support.

[0032] After the thermal blanket 1 is installed, the outer cover plate 2 is folded into a shape suitable for the sealing support and covers the thermal blanket 1. The outer cover plate 2 is fixed to the corrugated plate protective layer of the boiler and the compression ring 5 using a core-pulling rivet 3, thereby playing a heat insulation role and improving the stability of the structure. The application can solve the problem of over-temperature of the incineration waste heat boiler sealing support, reduce safety hazards and heat loss, and does not need to interrupt the operation of the boiler during installation, thereby facilitating on-site rapid installation.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
