Sea sand purification microwave processor and sea sand microwave purification system
The invention discloses a sea sand purification microwave treatment machine and a sea sand microwave purification system, and belongs to the field of sea sand purification, the sea sand purification microwave treatment machine comprises a groove type heat-resisting conveyor, and the groove type heat-resisting conveyor is sequentially provided with a feeding device, a plurality of microwave treatment devices and a discharging port in the conveying direction front and back; each microwave processor comprises a set number of microwave emitters, and the microwave emitters are located at the set height above a heat-resisting conveying belt of the groove type heat-resisting conveyor. According to the method, the sea sand is treated through microwave heating, harmful substances on the surface of a sea sand body lose activity and viscidity after being rapidly heated, the binding force with the sand body is rapidly reduced, then harmful substances such as chloride ions on the surface of the sand body are rapidly removed through elutriation and sand-water separation, and the treated purified sea sand can reach the basic state of river sand before entering the sea; and the chlorine ion content can reach 0.0002-0.002%, so that the concrete can be safely applied to construction engineering, cannot cause corrosion of steel bars and deterioration of concrete, and has the remarkable characteristics of good durability and low cost.
本发明公开了一种海砂净化微波处理机和海砂微波净化系统，属于海砂净化领域，其包括槽型耐热输送机，槽型耐热输送机上沿输送方向前后依次设置有进料装置、若干个微波处理器和出料口，每个微波处理器均包括设定数量的微波发射器，微波发射器位于槽型耐热输送机的耐热输送带上方的设定高度。本发明利用微波加热处理海砂，海砂砂体表面的有害物质在快速升温加热后，失去活性和粘性，与砂体的结合力快速降低，再通过淘洗和砂水分离，快速去除砂体表面如氯离子等有害物质，处理后的净化海砂可以达到入海前河砂的基本状态，氯离子含量可达到0.000％～0.002％之间，可安全应用于建设工程，不会导致钢筋锈蚀和混凝土劣化，具有耐久性好、成本低廉的显著特点。
