Pneumatic-propelling solid and liquid separation device

Abstract

The invention discloses a pneumatic-propelling solid and liquid separation device, which comprise a spiral shaft, wherein the center shaft of the spiral shaft is hollow; the shaft wall of the center shaft is provided with plural air outlets; one end of the spiral shaft is communicated with an air source; a valve is arranged on the air outlet; and the air source and the valve are opened to outwards release airflow with pressure. The pneumatic-propelling solid and liquid separation device has the advantages of simple structure and strong and powerful progressive driving force, various types of sludge can be smoothly processed, and the sludge processing efficiency, the sludge processing amount and the sewage dewatering rate are improved.

Description

【Technical field】 [0001] The invention relates to a solid-liquid separation device, in particular to a pneumatic propulsion type solid-liquid separation device. 【Background technique】 [0002] Existing solid-liquid separation device, such as the Chinese utility model patent whose publication number is CN2762865, "laminated spiral filter" disclosed on March 8, 2006, includes a screw shaft, and the outer diameter of the blade of the screw shaft is The face cover has a plurality of loop laminations, and the multiple loop laminations are composed of a fixed ring, a moving ring and an adjustment block, and the arrangement of the cycle laminations is that there are adjustment blocks and a fixed moving ring between every two fixed rings. Adjust the distance between the two fixed rings through the adjustment block. When the screw shaft rotates, the blades on the screw shaft move the moving ring, so that the moving ring and the fixed ring move relative to each other to form a dehydr...

Problems solved by technology

Obviously, to heat the sludge in the sludge tank to achieve the above effect, the energy consumed is very large, and the electric heating band is set on the wall of the sludge tank. For the whole tank of sludge There is a problem of uneven heating, the sludge near the tank wall is easy to be heated, and the sludge in the center of the tank is difficult to be heated

Therefore, it is difficult to achieve the effect of destroying the colloidal structure of the sludge and releasing water by cell rupture by setting a heating belt on the sludge tank wall to preheat the sludge, and the energy consumption is large, and the dehydration cost is high. Poor practicality
