Paper molding product drying equipment

Abstract

The invention discloses paper mold product drying equipment. The paper mold product drying equipment comprises a heating furnace, a blast blower and a drying box. The heating furnace is provided with an air inlet and a hot air outlet, an inner cavity of the heating furnace is provided with an air inlet passage, an air heating chamber and an air outlet passage, one end of the air inlet passage is communicated with the air inlet, one end of the air outlet passage is communicated with the hot air outlet, the air heating chamber comprises an air chamber and a combustion chamber, a plurality of heat collection pipes are arranged in the air chamber, one end of each heat collection pipe is communicated with the other end of the air inlet passage while the other end of each heat collection pipe is communicated with the other end of the air outlet passage, a chimney communicated with the air chamber is arranged at the top of the heating furnace, and the top of the heating furnace is further provided with an ash removal port and a feeding port corresponding to the combustion chamber. The blast blower is connected with the air inlet. The drying box is provided with a hot air inlet and an exhaust port, a rack is arranged in an inner cavity of the drying box, and the hot air inlet is connected with the hot air outlet. The paper mold product drying equipment is used for drying paper mold products large in thickness and size, high in drying efficiency, low in cost, safe and reliable, and climatic influences can be avoided.

Description

technical field [0001] The invention relates to the field of drying of paper molded products, in particular to a drying equipment for paper molded products. Background technique [0002] In the production process of paper molded products, when the thickness of paper molded products is less than 1mm, the four continuous processes of blank making → shaping → drying → demoulding can be completed on the mold. However, when the thickness of the paper molded product is greater than 1mm and its overall size is large, the three processes of blank making → shaping → demoulding can only be completed on the mold, and drying needs to be carried out separately. Drying of this type of paper molded product There are two commonly used methods, one is to transfer the paper molded products to the rack and dry them in the sun; the other is to steam dry. Although the first drying method has low energy consumption, it is easily restricted by the climate and drying place, and requires a lot of l...

AI Technical Summary

Problems solved by technology

Although the first drying method has low energy consumption, it is easily restricted by the climate and drying place, and requires a lot of labor, so the drying efficiency is low; although the second drying method has high drying efficiency, it needs to pass through the boiler separately. High-temperature steam is produced, which is costly and has certain dangers
