Porous up/down outlet air distributor

Abstract

The invention discloses a porous up / down outlet air distributor which comprises a frame body, clapboards, fan covers and an air feeder. The two upper and lower clapboards are fixed into the frame body; a plurality of fan covers are arranged at one ends of the clapboards; fan blades are arranged in the middle parts of the fan covers and sleeve rotary shafts; one ends of the rotary shafts are inserted into bearing seats; support rods are symmetrically welded onto the outer side walls of the bearing seats; support jaws are welded to one ends, far away from the bearing seats, of the support rods;spiral grooves are fixed onto the positions, on the inner side walls of the fan covers, on the support jaws; air inlets are welded to one ends, far away from the clapboards, of the fan covers; one ends of the air inlets communicate with the output end of the air feeder; a door body is hinged to the front side wall of the frame body; and a control panel is arranged on the top part of the door body.According to the porous up / down outlet air distributor, the drying efficiency is greatly improved by adopting the way of rotary flow equalization and convection exhaust, materials can be convenientlypicked and placed, and inner maintenance can be carried out conveniently.

Description

Technical field [0001] The invention relates to the technical field of hot air drying, in particular to a porous upper and lower air outlet distributor. Background technique [0002] In the prior art, hot air drying equipment mainly uses strong wind and electric heating to evaporate and remove excess moisture on the surface or inside of the material, so that the moisture contained in the material reaches a corresponding ratio, thereby improving Material characteristics, prolong storage time and other effects. [0003] However, there are still some problems, the specific problems are as follows: [0004] 1. The current application of wind energy is in discrete contact with materials. Therefore, the wind pressure and air volume of the materials are different, resulting in inconsistent drying degree, which in turn needs to extend the drying time of some materials, which not only increases energy consumption, but also Lead to material color and quality degradation; [0005] 2. The exist...

AI Technical Summary

Problems solved by technology

[0004] 1. The current wind energy application method is in contact with materials in a dispersed manner, so the wind pressure and air volume that the materials are exposed to are different, resulting in inconsistent drying degrees, which in turn need to prolong the drying time of some materials, which not only increases energy consumption, but also reduces Cause material color and quality to decline;

[0005] 2. The existing drying equipment usually needs to open the hatch when picking and unloading materials, and then stack them layer by layer. The operation is relatively cumbersome and the materials at the center are not exposed to the wind;
