Belt type filter press belt press filter dewatering process can be divided into the pretreatment, gravity dehydration, wedge area preloading dewatering and squeezing the four important stages of technology using the new equipment filter program-controlled automatic box filter press, membrane filter press, filter press sludge dewatering depth, the integration of sewage sludge treatment equipment, on-line precision filtration system such as the price is reasonable, reliable performance of the environmental protection filter products.

Structure is introduced

Belt press filter is mainly composed of drive device, under the frame, on the squeezing roller, belt, belt, belt tensioning device, filter belt cleaning device, discharge device, pneumatic system and electrical control system, etc.

Many Chinese industry chain, industry concentration is low, the high-end products matching research and development ability is low, the belt type filter press industry manufacturing technology level low phenomenon still exists, the import and export trade deficit is widening.

In a few years, it will be the high-speed oscillation period of the belt filter industry. The direct result of this kind of high-speed shock is the trend of polarization in the brand campaign.

There are definitely not so many companies that are expected to survive in the market in the next few years.

But this kind of high speed shock in the belt filter industry will bring huge opportunity, the result of concussion will make the market operation more rational.

The road to the localization of high-end electric power is "bumpy".

Components has become our country industry belt type filter press to high-end development, during the twelfth five-year government will continue to increase the belt type filter press high-end equipment parts and components of some well-known enterprises also stand out product has been widely used in environmental protection, municipal, mining, power, chemical industry, electronics, food, pharmaceutical, textile and so on all walks of life.

Working principle and workflow.

working principle

The dehydration process can be divided into four important stages: pretreatment, gravity dehydration, wedge precompression dehydration and crushing dehydration.

pretreatment stage:

The flocculated materials are gradually added to the filter belt, so that free water outside the flocs can be separated from the flocculation under the action of gravity, gradually reducing the moisture content of the sludge floss and the fluidity.

Therefore, the dewatering efficiency of the gravity dehydration section depends on the nature of the filter medium (filter belt), the nature of the sludge and the degree of flocculation of the sludge.

The gravity dehydration section removes much of the water from the sludge.

wedge-shaped pre-pressure dehydration stage:

Gravity sludge dewatering, liquidity is obvious, but it is still difficult to meet the requirements of liquidity squeeze dewatering section of the sludge, therefore, in between the squeezing sludge dewatering and gravity dehydration, added a wedge preloading dehydration, slight squeeze dewatering of sludge by the segment, removing the free water surface, liquidity is almost completely lost, thus ensure the sludge under normal circumstances will not be out in squeeze dewatering, create conditions for smoothly to squeeze dewatering.
