TECHNICAL FIELD
[0001] The utility model relates to solid waste reduction processing technical field especially relates to a novel sludge modification mixing device. BACKGROUND
[0002] At present, sewage treatment enterprises in China will produce a large amount of sludge with high water content in the process of treating sewage. Because the water content of these sludge is generally high, it usually needs to be dewatered before further treatment and disposal. However, the existing sludge dewatering equipment, such as concentrated belt dewatering machine and stacked screw sludge dewatering machine, is difficult to further improve the pressure of the equipment in the dewatering process due to its structure limitation, resulting in the water content of the dewatered sludge still being between 80%-85%. In order to continue to reduce the water content of the sludge, it is usually necessary to add a modified promoter for mixing modification treatment, and then high-pressure dewatering. However, in the process of treating industrial sludge and domestic sludge, the existing problems of low efficiency and insufficient uniformity of the mixing equipment seriously affect the modification effect of the sludge and the subsequent dewatering efficiency; in the prior art, CN201933003U discloses a sludge modifier, which realizes the physical modification of sludge through mechanical stirring, and its main features include:
[0003] 1. The inner and outer two kinds of stirring spirals with different spiral radii are arranged in the tank body, the radial and axial impact is generated by spiral stirring to improve the hydrophobicity of the sludge;
[0004] 2. The impact strength and uniformity of the sludge are optimized by adjusting the pitch and spiral radius of the spiral;
[0005] 3. The chemical modifier and water inlet are arranged to realize the mixing treatment of the sludge and the chemical modifier.
[0006] Although the device has certain sludge modification function, it still has the following defects and deficiencies in actual application:
[0007] In addition, although the stirring spiral of the existing device can stir the sludge to a certain extent, due to the limitation of its structure design and mixing method, it is easy to cause uneven distribution of the modification promoter, affecting the modification effect.
[0008] And for the sludge containing more lumps, the stirring spiral of the existing device lacks effective crushing mechanism, which makes it difficult for the modification promoter to penetrate into the inside of the sludge, reducing the modification efficiency.
[0009] At the same time, due to the design defects of the stirring structure, the sludge may accumulate or block at both ends or local area of the equipment, affecting the continuous operation and efficiency of the equipment.
[0010] Finally, the existing device is difficult to adapt to the characteristics of different types of sludge, especially when dealing with high moisture content or complex composition of sludge, the modification effect and mixing efficiency are further reduced.
[0011] Therefore, there is an urgent need for an improved sludge modification mixing device to solve the problems of uneven mixing, poor crushing effect, accumulation and blockage, and insufficient equipment adaptability in the prior art, so as to improve the sludge modification efficiency and the effect of subsequent dewatering treatment.
