Biological drying aeration device

Abstract

The invention discloses a biological drying aeration device. The device comprises an aeration panel, a dredging bolt panel and a bottom tray. The aeration panel, the dredging bolt panel and the bottomtray are arranged from top to bottom. Aeration holes are formed in the aeration panel. Dredging bolts are arranged at the positions, corresponding to the aeration holes, of the dredging bolt panel, and dredging panel air outlets are further formed. An aeration pipe is arranged on the bottom tray and is used for conducting aeration to the top of the bottom tray. Meanwhile, a control motor and a camshaft which is horizontally placed are arranged, and the camshaft is driven by the control motor to rotate. An extrusion plate is arranged above a cam on the camshaft and fixed to the bottom tray through an elastic assembly. When the camshaft rotates, the extrusion plate moves upwards under the action of the cam and then moves downwards under the action of the elastic assembly, the extrusion plate and the dredging bolt panel are fixed, the extrusion plate and the dredging bolt panel simultaneously move up and down, and when the extrusion plate and the dredging bolt panel move upwards, the dredging bolts pass through the aeration holes to achieve dredging operation. According to the biological drying aeration device, the aeration function is fulfilled, the aeration holes can be effectivelyprevented from being blocked, and the aeration effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a biological drying aeration device. Background technique [0002] In the biological drying process of organic waste treatment, in order to achieve the purpose of rapid material drying and water loss, the existing technology is to increase the aeration function in the reactor, and realize the gas entering from the bottom of the reactor by using an external air pump or fan. The reactor passes through the whole material, and the flow of gas in the whole process takes away the moisture in the material, making the material dry quickly. [0003] The current bio-drying reactors for organic waste can be divided into two types according to the direction of the stirring axis, namely vertical stirring reactors (such as silo type) and non-vertical stirring reactors. The former stirring axis is perpendicular to the ground; the latter The stirring shaft is parallel to the gro...

AI Technical Summary

Problems solved by technology

[0003] The current bio-drying reactors for organic waste can be divided into two types according to the direction of the stirring axis, namely vertical stirring reactors (such as silo type) and non-vertical stirring reactors. The former stirring axis is perpendicular to the ground; the latter The stirring shaft is parallel to the ground or at a certain angle. Because the stirring shaft of this type of reactor is parallel to the ground or at a certain angle, the material will form a force on the aeration hole due to gravity and stirring, making the material very It is easy to enter the aeration hole and form a blockage of the aeration hole

After the aeration hole is blocked, the efficiency of the entire reactor will be reduced, which is not conducive to the realization of rapid biological drying

[0004] In the prior art, in order to prevent blockage, the aeration holes are either set on the side wall of the reactor or on the top of the reactor, but from the actual effect, the exposed gas may not enter the material in both solutions It is sucked away by the fan, which greatly reduces the effect of aeration and increases energy consumption
