Sand washing wastewater treatment equipment - Sand washing plant wastewater treatment equipment

The sand washing mud dewatering machine produced by Shandong Shengshide Environmental Protection Technology Co., Ltd. adopts a super large roller diameter dewatering, which is the first of its kind in China. The super large roller diameter dewatering area is over 7m2 (with a bandwidth of 2500mm), which is 6 times the filtering area of the same model. The product is made of high-strength materials and can continuously filter a large amount of sludge. It has the characteristics of high processing capacity, high dewatering efficiency, and long service life, and is widely used in solid-liquid separation in various industries.For more information, please call 157-6364-8666

1、 Main functional features:

1. The main dewatering section adopts a very advanced and reliable vertical "S" - shaped roller filter press drainage structure design, which greatly exceeds the dewatering effect and processing capacity of traditional machines. The moisture content of the filter cake is 10-15% lower than that of ordinary machines, and the processing capacity is 30-60% higher than that of ordinary machines.

2. Low energy consumption, low-cost operation.
3. Advanced structural design and wide applicability.
4. The mesh belt speed regulation and correction control system has advanced technology, which can ensure long-term stable operation.
5. The selection of the dewatering belt for this machine is based on experiments and practical experience. Its permeability, wear resistance, viscosity, and cake stripping properties are better selected according to the actual materials, ensuring good dewatering effect and lower solid content of the belt washing water.
6. The transmission and electrical control system of this machine adopts well-known domestic brand products and components, which are very stable, reliable, durable, and have an extremely low failure rate.
7. The host gravity free dewatering adopts a unique multi roll large arc surface arrangement dewatering device, greatly enhancing the pre dewatering effect of low concentration slag. The advanced design of the clamping and squeezing structure in the main dewatering area ensures that the slag liquid separation runs in the opposite direction in the later stage without forming reverse osmosis.
8. Select high-quality anti-corrosion materials and spare parts for processing and manufacturing.
9. The parts of this machine that come into contact with sludge or water are made of 304 # high-quality stainless steel material. The remaining carbon steel parts are anti-corrosion treated with hot-dip galvanizing (which can be reheated and sprayed with plastic) or four layers of thickened fluorocarbon paint after surface sandblasting and rust removal for high-strength anti-corrosion treatment. Its acid and alkali corrosion and rust prevention ability can reach more than ten years.
10. Fully automatic operation, easy to operate and maintain.

3、 Working principle and workflow:

1 Working principle

The dewatering process of belt filter press can be divided into four important stages: pretreatment, gravity dewatering, wedge-shaped zone preloading dewatering, and press dewatering.

1.1 Preprocessing stage:

The flocculated material is gradually added to the filter belt, causing the free water outside the flocs to separate from the flocs under the action of gravity, gradually reducing the moisture content of the sludge flocs and decreasing their fluidity. Therefore, the dewatering efficiency of the gravity dewatering section depends on the properties of the filter medium (filter belt), the properties of the sludge, and the degree of flocculation of the sludge. The gravity dewatering section removes a significant amount of water from the sludge.

1.2 Wedge preloading dehydration stage:

After gravity dewatering of sludge, the flowability significantly decreases, but it is still difficult to meet the requirements of the pressing dewatering section for sludge flowability. Therefore, a wedge-shaped pre pressing dewatering section is added between the pressing dewatering section and the gravity dewatering section of sludge. The sludge undergoes slight pressing dewatering in this section to remove free water on its surface, and its flowability is almost completely lost. This ensures that the sludge will not be squeezed out in the pressing dewatering section under normal circumstances, creating conditions for smooth pressing dewatering.
