Moisture absorption hot air circular drying oven

Abstract

The invention discloses a moisture absorption hot air circular drying oven. The moisture absorption hot air circular drying oven comprises a box body, a drying chamber and a hot air circulating pipeline, wherein the drying chamber and the hot air pipeline are arranged in the box body; a gap among the box body, the drying chamber and the hot air pipeline is taken as a thermal insulation layer; the hot air circulating pipeline is connected with a top plate of the drying chamber and a bottom plate of the drying chamber; a plurality of ventilation holes are distributed in the top plate of the drying chamber and the bottom plate of the drying chamber; the lower part of the bottom plate of the drying chamber is provided with support columns which are connected with the box body; a circulating fan is arranged in the hot air circulating pipeline; a moisture absorption device is arranged in the hot air circulating pipeline; the hot air circulating pipeline is connected with an air supplementing pipe; a plurality of partition plates are arranged in the drying chamber; the inner wall of the drying chamber is provided with a heating pipe, a temperature measuring device and a safety pipe; the other end of the safety pipe is communicated with the atmospheric air; a safety valve is arranged at one end where the safety pipe is communicated with the atmospheric air; a control processing device is arranged outside the box body; the bottom of the box body is provided with pulleys. By adopting the moisture absorption hot air circular drying oven, hot air can be used circularly to the maximum extent, and the drying efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of chemical industry and pharmacy, especially the technical field of oven. Background technique [0002] In chemical, pharmaceutical and other industries, drying equipment is needed to dry materials. In order to save heat efficiency, hot air circulation ovens are often used. However, many hot air circulation ovens have dead ends in circulation, which is not conducive to the effective use of heat. The drying process The water vapor generated in the air must be effectively discharged or absorbed in order to achieve the purpose of efficient drying. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a moisture-absorbing hot air circulation oven, which can make the hot air circulate smoothly, effectively use heat, and absorb the generated water vapor in time to improve efficiency. [0004] In order to achieve the above object, the pres...
