What is the use mechanism of the double screw dehydrator

What is the use mechanism of the double screw dehydrator 1. The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration section to the dehydration section.

1. The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration section to the dehydration section. 2. The main body of the screw stacking dehydrator is a filtering device which is formed by a fixed ring and a moving ring overlapping each other, and a screw shaft penetrating through it. The former is the concentration section, and the latter is the dehydration section.

What are the reasons for the mud drop after dehydration of the screw type dehydrator:

Sometimes, the dispensing concentration is incorrect, the concentration is too high, and the flocculant is not easy to completely dissolve. Although it is enough to measure, the modulation effect is not good, sometimes it is due to unreasonable location of the dosing point, which leads to the flocculation time being too long or too short. The conditioning effect is not good. Usually due to the insufficient amount of sludge, when converted into shale, the dehydration performance is decreased. The test should be carried out to determine the appropriate dry sludge o-phenylenediamine.

Testing and adjustment should be carried out. The belt speed is too high. The tape speed is too large, the mud cake is thin, resulting in the decrease of solid content. The tape speed should be reduced in time. The thickness of mud cake should be generally 5-10 mm. The belt tension is too small. This does not guarantee enough extrusion pressure and shear force, so that the tension should be increased properly in order to reduce the solid content. Filter, can not filter water, is to reduce the solid content, should stop operation, wash the filter belt.
