The boiler with the heat preservation effect is obtained by upgrading and reforming a traditional boiler, and concretely comprises a base 1 for supporting and a boiler body 2, wherein the boiler body 2 is fixedly arranged above the base 1. In the scheme, the boiler body 2 is arranged to be cylindric intermediate layer, and the intermediate layer of boiler body 2 sets up insulating layer 23 near the outside and is used for avoiding boiler high temperature and scald personnel when heating, is provided with heat preservation 24 near the inside and outside and is used for carrying out heat preservation in it. The interior of the boiler body 2 is divided into an upper water cavity 21 and a lower combustion cavity 22 by a metal pan bottom 27, cold water is placed in the water cavity 21 during use, and then the metal pan bottom 27 is heated by adding biomass fuel in the combustion cavity 22 for combustion, so that the water in the whole water cavity 21 is heated. For better heat preservation, a liner 25 is arranged above the metal pan bottom 27 of the water cavity 21, and the liner 25 is a heat preservation liner, of course, the heat preservation liner needs to be made of a material with higher strength due to larger heating water quantity, and of course, the heat preservation liner can also be arranged as a metal liner according to specific requirements. To facilitate the combustion of the biomass, a layer of firebrick 26 is provided in the combustion chamber 22 in the lower portion of the metal pan bottom 27. In order to facilitate the addition of materials and slag tapping, a material door 3 is arranged on one side of the combustion chamber 22, and meanwhile, in order to enable the combustion to be more complete, a blower 6 is arranged at one end of the combustion chamber 22, and a smoke outlet pipe 7 is arranged at the other end of the combustion chamber. A first water inlet pipe 9 and a water outlet pipe 10 are respectively arranged at two ends of the water cavity 21.

After the combustion is stopped, heat energy is transferred into the combustion chamber 22 through the metal pan bottom 27, if the material door 3 cannot be tightly closed, the heat is emitted into the air through the material door 3, so that the heat preservation effect is reduced, therefore, after the material door 3 has the same layer structure as the combustion chamber 22, the material door 3 needs to be sealed after the combustion is stopped, the material door 3 is set as a sliding door, a sliding way 4 for sliding is arranged on one side of the boiler body 2, and then the material door 3 is sealed with the boiler body 2 through a pressing device 5.

In the utility model, a compressing device is provided, the compressing device 5 comprises a bracket 51 and a hydraulic telescopic column 52, the bracket 51 is suspended at the position, close to the middle, of the two end edges of the material door 3, the two ends of the bracket 51 are fixedly arranged on the boiler body 2, the sliding of the material door 3 cannot be influenced, then the hydraulic telescopic column 52 is arranged on the bracket 51, when the material door 3 is closed, the hydraulic telescopic column 52 stretches out to compress the two ends of the material door 3 to the boiler body 2, so that sealing is realized, and sealing strips are arranged on the material door 3 to better seal. After the material door 3 is sealed, the page of the smoke outlet pipe 7 needs to be sealed, and therefore, a valve 8 for sealing a pipeline is arranged on the smoke outlet pipe 7.

In another embodiment, in order to reduce the heat transfer from the water cavity 21 to the combustion chamber 22, an interlayer is provided at the center of the metal bottom 27, a heating wire is provided in the interlayer, the heating wire is connected to the electric heater 11, and the electric heater 11 is disposed at one side of the boiler body 2. A second water inlet pipe 12 is arranged on one side of the metal pot bottom 27 and communicated with the interlayer of the metal pot bottom. In this way, in the use process, the electric heater 11 firstly heats the water in the metal pan bottom 27 to a certain temperature, then the combustion chamber 22 heats the forward water cavity 21 to heat cold water, after the combustion chamber 22 stops heating and is closed, the temperature of the combustion chamber 22 is reduced along with the time, and the water layer in the metal pan bottom 27 can form a heat-insulating layer to reduce the heat transfer to the combustion chamber 22 as much as possible because the temperature is not changed greatly, so that the heat-insulating effect is improved, and the heat-insulating duration is prolonged.

Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
