The hot blast stove is universal equipment widely applied to the fields of food, medicine, printing, packaging, mechanical manufacturing and the like. The hot blast stove can be used for heating air and outputting hot air, and can also be used for drying ceramic, paper (electronic, chemical) and other products, and the application is wide.
The existing hot blast stove is mainly formed by assembling functional components such as a heater, a fan, a temperature control system and the like, and has the problems of high combustion energy consumption and overhigh hot air temperature.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model aims to provide a hot blast stove.
In order to achieve the above purpose, the utility model provides a following technical scheme: the hot blast stove comprises a hot blast stove body, wherein a vertical first air guide pipe is arranged in the hot blast stove body, two ends of the first air guide pipe are connected with second air guide pipes which are horizontally arranged, a burner is arranged on one side, located on the first air guide pipe, of the hot blast stove body, a plurality of air inlets are formed in the side wall, located on the burner, of the hot blast stove body, the first air guide pipe is connected with an air inlet pipe towards the side wall of the burner, the other end of the air inlet pipe is connected to one of the air inlets, and the other ends of the two second air guide pipes extend out of the outer side wall.
By adopting the technical scheme, the air in the hot blast stove is heated through the burner, so that the hot air in the hot blast stove heats the first air guide pipe and the second air guide pipe, the cavity inside the paint is heated, the hot air in the first air guide pipe and the second air guide pipe is pumped out through the suction fan, and the direct pumping out of the hot air in the hot blast stove to cause the overhigh hot air temperature is avoided.
The utility model discloses further set up to: the inner wall of the hot blast stove is provided with a third air guide pipe parallel to the second air guide pipe, one end of the third air guide pipe is communicated with the inside of the hot blast stove, the other end of the third air guide pipe is arranged in a sealing manner, a plurality of connecting pipes are connected between the third air guide pipe and the second air guide pipe, and a plurality of second air inlets are formed in the side wall, located on the combustor, of the hot blast stove.
Through adopting above-mentioned technical scheme, at the suction fan during operation, in the hot-blast furnace partial hot-air entered into the third air duct to enter into the second air duct through the connecting pipe, in order to guarantee that the air in the second air duct reaches required temperature, and make the new trend enter into the hot-blast furnace inside from the second air inlet.
The utility model discloses further set up to: the first air guide pipe, the second air guide pipe and the third air guide pipe are all made of high-temperature-resistant stainless steel.
Through adopting above-mentioned technical scheme, through adopting high temperature resistant stainless steel, promote the conduction efficiency of temperature to guarantee the heating effect to in first air duct and the second air duct, and can promote its life.
The utility model discloses further set up to: and the outer side wall of the second air guide pipe, which is positioned outside the hot blast stove, is sleeved with a heat insulation layer.
By adopting the technical scheme, the heat loss of hot air when passing through the second air guide pipe is reduced through the heat-insulating layer, the energy loss is reduced, and the air outlet temperature of the hot blast stove is ensured.
