Stone powder separation system for stone sewage and working method

Abstract

The invention discloses a stone powder separation system for stone sewage. The stone powder separation system comprises a stone powder collection device, a first transfer frame, a first separation device, a sewage pool, a clear water pool and an isolation pool, the first separating device comprises a first supporting mechanism, a first screw mechanism and a first driving mechanism; the first supporting mechanism comprises a first supporting frame and a first connecting groove, and the first supporting frame is arranged at the bottom of the first connecting groove, so that one end of the first connecting groove is higher than the water surface in the sewage pool; the first screw mechanism is arranged in the first connecting groove, and the first driving mechanism is arranged at the end, higher than the sewage surface, of the first connecting groove and used for driving the first screw mechanism to separate stone powder in sewage from water. By arranging the stone powder collecting device, the transferring frame, the separating device, the sewage pool, the water purifying pool and the isolating pool, integrated separation of stone sewage stone powder and water separation, stone powder collection and purified water collection is achieved, the separation effect is good, the efficiency is high, the maintenance cost and the production cost are low, and the device is suitable for industrial production.

Description

technical field [0001] The application relates to a stone powder separation system and working method for stone sewage, belonging to the technical field of stone processing. Background technique [0002] With the strengthening of environmental protection in our country, the sewage treatment of stone processing has attracted more and more attention. At present, the sewage treatment system of stone processing has the disadvantages of large area, many requirements and high cost, which limit the practical application of sewage treatment system. The production process of stone processing mainly includes cutting, grinding, polishing and other processing procedures, which belong to the physical processing process. Stone sewage is stone powder, crushed stone, cooling water and other materials produced after sawing or grinding of marble, granite and other stone materials. A mixture of substances, which contains a large amount of stone powder (the main chemical composition is silicon ...

AI Technical Summary

Problems solved by technology

However, the sedimentation tank sedimentation treatment method used for coarse particles in wastewater has the disadvantages of large area and long cycle.

At present, stone processing enterprises generally use mechanical devices to compress the solids in stone sewage into filter cakes, and then landfill them or send them to processing plants for further processing. Landfill processing will not only pollute land resources, but also waste stone resources; The filter cake needs to be sorted again, which indirectly increases the economic cost

Some of the existing stone powder separation devices have complex mechanical structures, high maintenance and production costs, and cannot achieve stone powder separation, stone powder collection and sewage purification at the same time
