Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] combine Figure 1 to Figure 4 , a blade heating device, comprising a blade heat exchanger 1, a first heat source inlet 4, a heat source first outlet 5, a front air distributor 6, a rear air distributor 7, a left air outlet bellows 8, and a right air outlet bellows 9. Filter 10, fan 14, heat exchanger 15, compressor 18. The top of one end of the paddle heat exchanger 1 is provided with a material inlet 2, and the bottom of the other end is provided with a material outlet 3. The heat source is fixed on the paddle heat exchanger 1 through a flange. The first inlet 4 is on the same side as the material outlet 3 for Connect the heat source (i.e. tank). The first outlet 5 of the heat source is on the same side as the material inlet 2, and the first outlet of the heat source is fixedly connected to the paddle heat exchanger 1 through a flange for connecting...

Abstract

The invention discloses a paddle heating device which comprises a paddle heat exchanger, a heat source first inlet, a heat source first outlet, a front air distributor, a rear air distributor, a left air outlet box, a right air outlet box, a filter, a fan, a heat exchanger and a compressor, wherein the paddle heat exchanger is selected as main equipment, and the air distributor with axial air inlet is arranged, so that heat and mass transfer efficiency can be improved, and the heat exchange performance is remarkably prior to that of conventional paddle heat exchangers. Due to adoption of exhaust circulating heating, the heating process can be realized by the heat exchanger as well as the compressor. The heating pipe is arranged in an air duct wall, so that secondary heating of exhaust can be realized, and the exhaust can be used for heating materials in various temperature zones.

Description

technical field [0001] The invention belongs to the field of material heating devices, in particular to a paddle heating device. Background technique [0002] my country began to research and develop blade heating devices in the 1970s, but due to limited conditions, the development has been relatively slow for many years. In recent years, with the expansion of domestic market demand, the introduction of foreign advanced equipment and the deepening of domestic research and development work, the technical level of domestic blade heating devices has been greatly improved. [0003] The paddle heating device is a continuous heating equipment mainly based on heat conduction and capable of conveying materials. It is suitable for heating or drying granular and powder materials, and has a good heating or drying effect on viscous and paste materials. Since the material side of the paddle heating device is usually the side that controls the thermal resistance, it is particularly impor...
