Advantages of multi-disk screw press for processing slaughter sludge

 

The working principle of multi-disk screw press:

The main body of the dehydrator is a filter device formed by a fixed ring and a floating ring stacked on each other, and the screw shaft runs through it. The front section is the concentration section, and the rear section is the dehydration section.

The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration part to the dehydration part.

The rotation of the screw shaft pushes the sludge to be transported from the thickening part to the dewatering part, and at the same time drives the swimming ring to clean the filter seam to prevent clogging.

After the sludge is concentrated by gravity in the thickening part, it is transported to the dewatering part. In the process of advancing, with the gradual reduction of the filter seam and the pitch, and the blocking effect of the back pressure plate, a great internal pressure is generated, and the volume is continuously reduced. , to achieve the purpose of full dehydration.

Treatment of slaughterhouse wastewater with multi-disk screw press:

The slaughtering industry is an important civilian production industry. In order to ensure food safety, the operations of slaughtering enterprises are gradually standardized. On the basis of ensuring the safety and hygiene of the slaughtering process, the incidental sewage and sludge should also be properly handled to avoid environmental pollution. Slaughter sludge is the sludge produced after biochemical treatment. It contains a part of fur, oil and other impurities, which is easy to stink. If it is not treated, it will produce odor and mosquitoes. Most slaughter companies choose multi-disk screw press to process slaughter sludge.

The operation and maintenance of the sewage station in the slaughterhouse generally requires about three people. If the labor required for sludge dewatering is too large, labor costs will increase. Traditional filter presses require workers to manually clean the filter cloth, which is inefficient and requires human and sludge contact. The multi-disk screw press does not require manual cleaning of sludge during operation, and does not require additional workers to operate. And the dehydration efficiency is higher, the electricity and water consumption are very low.

The advantages of the multi-disk screw press in the treatment of slaughter sludge are obvious.
