Embodiment Construction

[0014] The concave-convex roller pressure device of the belt filter press includes an annular flocking filter belt 1 and a pressure roller 2. A driven roller 3 and a driving roller are respectively arranged on both sides of the arc surface of the pressure roller 2. 4. A number of extrusion rollers 5 are arranged under the pressure roller 2. The flocking filter belt 1 is set on the driven roller 3, the driving roller 4 and the extrusion roller 5, and the pressure roller 2 and the extrusion roller The shaft 5 can squeeze the flocking filter belt, and the flocking filter belt 1 is also provided with a number of tension rollers 6 to make it in a tensioned state, and the circumferential surface of the strong pressure roller 2 is a concave-convex structure of a gear.

[0015] The diameter of the pressing roller 2 described in the present invention is larger than the diameters of the driving roller 4 , the driven roller 3 and the extruding roller 5 .

Abstract

The invention relates to a concave and convex rolling shaft pressure device of a belt filter press. The concave and convex rolling shaft pressure device of the belt filter press comprises a ring-shaped flocking filter belt and a pressure rolling shaft, wherein a driven rolling shaft and a driving rolling shaft are respectively arranged at the two sides of the circular arc surface of the pressure rolling shaft; a plurality of extrusion rolling shafts are arranged under the pressure rolling shaft; the flocking filter belt is sheathed on the driven rolling shaft, the driving rolling shaft and the extrusion rolling shafts, and is extruded by the pressure rolling shaft and the extrusion rolling shafts; the flocking filter belt is also internally provided with a plurality of tension rolling shafts used for enabling the flocking filter belt to be in a tensioning state; the circumferential surface of the pressure rolling shaft has a concave-convex structure of a gear. The concave and convex rolling shaft pressure device is simple in structure, good in dehydration effect, good in mud cake stripping effect, little in sludge residue, not easy to block and small in cleaning water quantity, and thus reducing secondary pollution.

Description

technical field [0001] The invention relates to a sludge dewatering device of a filter press, in particular to a concave-convex roller pressing device of a belt filter press. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. It will pose a serious threat, therefore, the sludge should be treated with great care. Sludge dehydration is a sludge treatment method that removes water from liquid primary, concentrated or digested sludge and converts it into semi-solid or solid sludge. The water content of the dewatered sludge can be reduced to 50% to 80%, depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment. The sludge with high water content produced in the sewage treat...
