Description

Furnace improved structure

technical field

The invention relates to an improved structure of a furnace body, in particular to an improved structure of a furnace body applied to heat insulation, cooling and maintaining high temperature thermal efficiency structure of the furnace body.

Background technique

According to the currently known structures of household or industrial stoves, the heat-insulating walls are sandwiched by metal cladding with heat-insulating materials, or heat-insulating materials are arranged outside the metal cladding, and the outer surface of the metal cladding is reduced by intervals. The temperature of the surface, such as Patent No. M330350, M343690, M356789 and M301629, also has a heat insulation structure with a vacuum layer or an inert air layer in the metal clad layer. Reduce the temperature of the outer surface of the metal cladding, such as patent certificate No. M 360911 and patent announcement Nos. 381005 and 319684, and the metal cladding on the wall of the above-mentioned stove is combined and fixed by ordinary screws or a metal hemming frame However, when the furnace core of the furnace structure is heated, the temperature of the heat source is as high as 600-800 degrees, and the metal clad layers are combined and fixed in the above-mentioned way, so that the contact area of the frame between the metal clad layers is large, and the heat transfer rate is increased. However, the temperature cannot be effectively lowered. Although the method of metal folding and enclosing the frame reduces the temperature of the wall surface, it still maintains a high temperature of about 244,280 degrees after testing. In addition, the metal cladding is fixed by ordinary screws. The temperature of the wall surface is also reduced, but After testing, it still maintains a high temperature of about 221-245 degrees. Therefore, the known stove structure that uses charcoal and gas as heat sources does not have a heat-insulating effect as described, and only has a segmented structure due to the high temperature generated during use. cooling, so it cannot be effectively used indoors.

In addition, currently known household or industrial stove structures also have water-cooled cooling pipes installed on the wall or waste heat is recovered to generate hot water, that is, a plurality of circles of connected and upwardly extending surrounding water pipes are arranged on the inner peripheral edge of the wall, and around the surrounding water pipes An upper opening is provided at the upper end of the water pipe, or an interconnected water channel is formed at the closed hollow part of the wall of the stove, and the head and end of the water channel are respectively connected to a water inlet pipe and a water outlet pipe. , the hot water that has been subjected to heat exchange is discharged to reduce the temperature of the wall surface of the stove, such as the patent case of the patent certificate No. M296668 and the patent announcement No. 411831. However, the temperature of the wall surface of the stove cooled in the above-mentioned way can reach ideal temperature, but it needs to use the pumping motor and the water inlet and outlet pipes. The production and maintenance costs of this structure are high, which is not in line with environmental protection and green energy awareness, and the high temperature and dry air emitted by the furnace heating cannot provide protection for increasing humidity. The effect of human respiratory organs also cannot be effectively used indoors, and the first high temperature produced in the furnace body cannot be effectively maintained.

In summary, the problems existing in the known structures of the prior art are listed as follows:

1. Poor use safety: the wall is sandwiched by metal cladding with thermal insulation materials, or a vacuum layer or an inert air layer is set in the metal cladding, or surrounding water pipes and water channels for heat exchange are installed on the wall, but it cannot Effectively reduce the temperature of the outer wall surface of the metal clad layer. The outer wall surface is still at a high temperature for a long time, and continues to radiate from the surrounding wall surface due to heating, so its safety in use is poor.

2. Low thermal efficiency: high temperature and dry air are emitted from the top of the wall, which absorbs the moisture in the user's body and lungs, and at the same time takes away a large amount of heat, reducing the first temperature of the heating zone in the stove. If there are only surrounding water pipes and water channels for heat exchange but no thermal insulation layer, the heating time needs to be doubled, so its use efficiency is low.
