DY Belt type press Filtering machine
With the rapid development of industrial and urban construction, industrial wastewater and domestic sewage is increasing.In order to prevent pollution, protect the environment, must be processed sewage.Generated in wastewater treatment solution containing high amounts of sludge, which must first be dewatered sludge treatment, or can not transport and utilization.Currently more for mechanical sludge dewatering, and Belt type press Filtering machine and other mechanical sludge dewatering compared with the advantages of high efficiency and continuous operation, so the increasingly widespread application.
How it works:
Belt type press machine dehydration process can be divided into pre-processing, gravity dehydration, dehydration and dewatering wedge four important stages.
1.Preprocessing stage:that of the original mud mixed with flocculant process.
2.Gravity dewatering stage: Theflocculated material was added through the pump filter belt, between the free water in the flocculation and gravity
|Floc separation, so that the water gradually reduces the sludge floc, liquidity deteriorated.Gravity sludge dewatering section removes most of the moisture.
3.Wedge preload dehydration stage:gravity sludge dewatering, liquidity deteriorated significantly, but still difficult to meet the press sludge dewatering segment mobility requirements, therefore, between the segment and the gravity dewatering sludge dewatering segment, plus a wedge preload dewatering segment, the segment after sludge dewatering by a slight squeeze liquidity almost completely lost, thus ensuring the sludge under normal circumstances would not be out in the dewatering segment is smoothly conduct dewatering create conditions.
4.Dewatering stages:the first refers to the sludge dewatering roll after entering in the role of the filter with the tension of the upper and lower filter cake sandwiched around with different size press rolls repeatedly squeezing and shearing, capillary action of removal of water addition to a number, so that the cake moisture decreases.
