How can we improve the efficiency of raw sludge dewatering?

First of all, we need to know its principle. When the sludge dewatering machine works, it is generally the physical and chemical reaction of the sludge pressure filtration process. The physical process mainly depends on the squeezing and draining function of sludge dewatering. The chemical reaction is to synthesize the small particles of sludge water into larger particles through coagulants and other chemical components, which is beneficial to squeezing and draining. The main component is flocculant, commonly known as pam, The small particles in the sludge are chemically aggregated into macromolecular flocs and enter the sedimentation and pressure filtration process.

Here we should note that the flocculant needs to be used together with the dehydrator to play its role, and the effect of directly putting it into the sewage will not be very good. Therefore, in order to provide the efficiency of the sludge dehydrator, it is necessary to put flocculant in the process of use.

Of course, there are also many kinds of flocculants, including inorganic flocculants and organic flocculants. Among them, inorganic flocculants can be classified into iron and aluminum according to metal salts, as well as modified cations, cationic organic, and various types of acryloyl cations. Different types of flocculants have different effects on sludge water of different properties, Therefore, different flocculants should be added according to the nature of sludge water to achieve better results.

What should I do if there is a sudden interruption?

First, cut off the power immediately, and then check whether there is a mechanical failure, and check which component is broken. The replacement and overhaul. Eliminate all component causes and restart the test.

If it is a common sludge dehydrator, there is a button on the installation device. When the equipment encounters an emergency, it is necessary to immediately press the stop button to stop the sludge dehydrator immediately. If you want to restart the sludge dehydrator after the situation is eliminated, please rotate in the direction of the arrow on the emergency stop button to make the button float, and then restart the sludge dehydrator.

How should we pay attention to it in daily situations?

During the operation of the sludge dewatering machine, the operator must always pay attention to its operation. If any abnormality is found, stop the machine immediately to find out the cause. After the fault is eliminated, restart the machine, check whether all equipment is in normal condition, and regularly add lubricating oil at the designated position!
