Therefore, the chamber filter press is suitable for flotation of -0.5mm. Although the higher feed concentration is beneficial to the improvement of pressure filtration effect, the feed concentration should not be too high. The filter press we often use is the same. Its efficiency directly affects the efficiency of enterprises, so it should be faced squarely. However, the filter pressing time directly affects the processing capacity of the box filter press. Today, the belt filter press will give you a few tricks.
Secondly, attention should also be paid to the feed concentration and pressure.
A Smart Way to Improve the Efficiency of Press Filter
6. After dewatering, sludge and other suspended solids should be well pressed into mud cake, resulting in low water content of mud cake, so as to achieve good dewatering effect. If the pressure is too high, it will help to shorten the cake-making time and reduce the moisture content of the filter cake, but the effect is not significant. The longer the filter pressing time is, the lower the moisture content of the cake is. In this way, not only the working efficiency of the filter press can be improved, but also the service life of the filter press can be promoted. - The higher the mesh content of 200 mesh, the lower the processing capacity of filter press and the higher the moisture content of filter cake.
First of all, we will talk about the size composition of the feed. The higher the feed pressure, the lower the moisture content of the filter cake. It also shows that the pressure filtration time is too long, but the moisture content of the cake is not significantly reduced.
4. Auto-rectification and alarm system should be provided. Otherwise, the belt will be damaged and the service life of the belt will be reduced. The optimum feeding pressure is 0.4-0.8 MPa. Its working efficiency is closely related to the water content of filter cake, solid content in filter fluid and hourly treatment capacity of filter press, and factors such as feed concentration, feed pressure, feed size composition and filter pressing time.
1: Filter cloth and filter plate scrap: adjustable feed pump model, check whether the pressure of hydraulic station is abnormal, timely replacement of scrap filter cloth and filter plate.
In order to improve the working efficiency of the filter press, we must first understand the working principle of the box filter press. The higher the feed concentration, the shorter the time it takes to fill the filter chamber with the filter towel slime, the stronger the treatment capacity of the filter press and the lower the moisture content of the filter cake.
1. Manipulation should be simple and convenient. Otherwise, it is difficult for ordinary people to operate.
Nowadays, with the rapid economic development, the influence of machine efficiency is also increasing. However, due to the coarseness of the feed particles, the quick settling of the slime and the poor mobility, the central hole of the filter press is easily blocked and the cake formed is loose.
Friends who often use filter presses may think that scrap filters are useless and can be sold as scraps. This is not the case. The scrap of filter presses can be divided into different degrees. Some scrap filters can be reused. Most of the slightly scrap filters are scrap parts, only need to replace scrap zeros. It's OK. If the whole machine is scrapped, it's really scrapped. There's no need to reuse it. In summary, the efficiency of filter press is mainly affected by the above factors, so we should pay attention to these application factors in future equipment operation.
3. How many cubic meters of water consumption per hour, whether the filter cloth is wear-resistant, how much filter material is needed, and the noise level of the equipment. The quality of a belt filter press is directly related to the sludge treatment capacity of the equipment, so how can we choose a good belt filter press? Now let's take a look with Jiuding Filter Equipment Company.

3: There are many reasons for the scrap of the hydraulic station: the filter plate is not compacted, the compaction pressure exceeds the scale pressure, oil leakage and so on. The main reasons are that the oil wiring is reversed, the solenoid valve is broken, and the sealing ring is worn seriously. It is OK to find the right reasons and replace the damaged parts when necessary. Generally, the feed concentration is over 300 g/L, preferably around 500 g/L, and the maximum is not more than 800 g/L.
In addition, it is necessary to control the filtering time. How to distinguish the scrap degree of filter press? Below is a small part for you to analyze the scrap degree of waste filter press:
If the feed size is coarse, the filter function is good and the cake-making time is short. The content of - 200 mesh in the feed directly affects the filtering effect.
2: The girder of the frame can not be repaired or replaced if it is broken or deformed. Otherwise, if an accident happens, it will be worthless.
As we all know, belt filter press is a common equipment in sludge dewatering equipment. It is widely used in municipal sludge, tailings, coal sludge from coal washery, paper mill sludge, car wash sludge and sludge from various sewage treatment processes.
2. Whether the dehydration process is not disorderly or not, the amount of treatment is not large.
5. How about the power consumption? If the power consumption is large, the operating cost will be increased.
