The quality of the environment has a relatively large impact on our lives, so the country pays more attention to our environment, coupled with the increasing awareness of environmental protection, the desire for green landscapes is growing, and the research and development of environmental protection equipment for heavy industry is also increasing. Go deeper. As an equipment in a sand making and washing production line, the filter press is mainly used to treat the muddy water and mud produced after sand washing, and its performance is also improving day by day.
Briefly analyze the advantages and disadvantages of belt filter presses commonly used in sand making and washing production lines.
The advantages of belt filter press are as follows:
1. The utility model is simple in structure, convenient to manufacture, less accessory equipment, and low energy consumption.
2. The belt filter press is cheap, the later maintenance and management is relatively simple, and the filter belt replacement is also more convenient. Many accessories in the equipment can be purchased locally by the user;
3. It can treat the sludge that the sludge centrifuge cannot handle. For example, in the sludge produced by railway systems, oil fields, and diatomaceous earth sewage treatment, there are problems such as large sludge volume and high viscosity, which cannot be treated by sludge centrifuges. Belt filter presses can achieve better effect.
4. Strong continuous working ability, large dehydration processing capacity, good filtering effect, 24 hours work, one person can easily take care of multiple machines.
5. Small vibration and low noise.
6. Stable and safe operation.
7. It is suitable for various industries such as sludge treatment in sand washing plants, mud pile treatment, river dredging, dry tailings, plant slag pressing, stone cutting sludge treatment, electroplating plant sludge treatment, etc.
8. Environmental protection and energy saving, which can achieve national emission standards. The filter belt can be cleaned with filtered water so that the water resources can be recycled.
The belt filter press in the sand washing production line has the following disadvantages:
1. The common polyacrylamide content is high, the dosage is larger than the centrifuge, and the operating cost is high.
2. The water content of the sludge can be processed to about 70%, and the processed mud cake can be reused after secondary treatment, realizing the real waste into treasure.
3. The filter belt of the belt filter press needs to be washed with a lot of water. If it is not cleaned, it will block the filter belt and affect the effect.
4. Sludge is easy to lose, the site is unsanitary, and the smell is strong.
5. The filter belt is easy to run off and the sludge has a high moisture content.
Belt filter press is suitable for dewatering of inorganic sludge, but not suitable for dewatering of organic sludge.
