The screw dehydrator is one of the most common equipment in the solid-liquid separation process. Its basic principle relies on the thrust of the screw to push the material into the screen. The back pressure device performs back pressure on the screen outlet. The screen is compressed by the binding force of the screen, the liquid phase flows out of the screen hole, and the solid slag is discharged from the slag outlet (see figure).

    Compared with other forms of press dehydrator, screw dehydrator has obvious advantages:

    1. Continuous in and out of materials, high efficiency, easy to realize mechanized production.

    2. Few transmission parts, low failure rate, stable and reliable operation.

    3. The moisture content of the slag after pressing is low, and the dehydration effect is good.

    4. Small footprint and simple equipment installation.

    With the combination of mechanical design and intelligent design of fluid mechanics, the design of the screw dehydrator is more customized and professionalized. The performance of the screw dehydrator is being improved more, making the performance and market application of the screw dehydrator more extensive. Recognition.

    The excellent performance of the screw dehydrator is also manifested in the relatively complex composition of materials, such as Chinese medicine residue, bone meal, kitchen waste, tail waste, waste plastic waste from recycled paper and paper mills, etc., mostly a mixture of several materials, belt press Both the machine and the plate and frame filter press are difficult to adapt to the normal operation of the equipment. The high hardness of the solids in the wet material will also affect the use of the belt press, and the screw press is not affected by these factors and can achieve continuous and efficient operation. The energy consumption of the equipment itself is compared with the result, the cost Relatively low.
