Description

Pulp molding drying device Technical Field The utility model belongs to the field of paper pulp drying equipment, and particularly relates to a paper pulp molding drying device. Background Pulp molding and drying are key process links for determining product quality, energy consumption and production efficiency, and currently, a heat dissipation type multi-layer drying line heats air by using a radiator and then heats products by using hot air. The method is characterized in that the product is dried by evaporating water, the product is dried by utilizing high-temperature heat conduction oil to flow through a radiator, radiating fins of the radiator generate heat, when the temperature is lower and the wet air flows, the wet air is heated to become high-temperature dry air with small relative humidity, the high-temperature dry air passes through a drying box to dry paper pulp, the high-temperature dry air passes through a drying channel of the drying box from the upper layer to the lower layer, the humidity is increased, the temperature is reduced to become wet air, but when the heat conduction oil is introduced in the drying process, additional high-temperature air is generated, and the high-temperature air is generally directly discharged into the atmosphere, so that energy is wasted, and more energy is consumed for reheating the low-temperature wet air, so that the prior art needs to be improved in order to avoid the defects in the prior art. Disclosure of utility model The utility model aims to provide a pulp molding drying device which can utilize external high-temperature air in the pulp drying process to achieve the effect of reducing energy consumption. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a paper pulp molding drying device, includes wind channel and lower wind channel, the bottom intercommunication in wind channel has the radiator, be provided with the fin in the radiator, the bottom intercommunication of radiator has the stoving case, and the paper pulp setting of waiting to dry is in the inside of stoving case, the inside of stoving case with the lower wind channel intercommunication forms the stoving passageway, the output in wind channel is provided with circulating fan down, circulating fan's output be connected with the circulating wind channel of wind channel intercommunication, the wind channel go up the radiator the stoving case the lower wind channel with circulating wind channel forms the return circuit of circulation, be provided with the wet pipeline of arranging of communicating with external environment on the circulating wind channel, the circulating wind channel includes ascending passageway of orientation and the horizontal channel that the level set up, the horizontal channel with upward wind channel intercommunication, ascending passageway with be provided with curved arc passageway between the horizontal channel, be connected with the air-supply line with external environment intercommunication on the arc passageway, the air-supply line level sets up.
