Hello, everyone. Today, a technical engineer from Works Chemical is teaching you how to solve the problem of pressing mud and not wetting filter cloth. Sludge dewater agent manufacturers believe that there are many reasons why the filter press does not press, from the working principle of the filter press, the whole equipment is provided by the feed pump filter power, filter cloth starts as the filter medium, when the filter cake is formed, it will be used as the filter medium, and finally achieve the solid-liquid separation state. The filter plate of the filter press acts as a support to form a filtration chamber.

At present, the fine processing of minerals often emphasizes higher purity and finer particle size, such as calcium carbonate, kaolin, titanium dioxide, bentonite, etc., and even reaches the micron or nanometer level, so the formation of slurry solid-liquid separation is more difficult, often can not be filtered, not dry, filter cake dense, high moisture content, the need for a spade frame and other phenomena, seriously affecting production efficiency. So, in the actual production process, how to solve the problem that the plate and frame filter press is not formed? Technical engineers at Works Chemical recommend sludge conditioners.

Because, the most important thing is to reduce the moisture content of the sludge. Works Chemical's self-developed sludge conditioner for high-moisture sludge effectively reduces the moisture content of the sludge, dehydrates the sludge further, and finally reaches the plate and frame press to press the mud into chunks. Sludge conditioner is a chemical agent that can change the surface structure of sludge, reduce the solid surface load of sludge, reduce the specific surface area of sludge and destroy the structure of bacteria. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on.

The sludge conditioned by the sludge conditioner is injected into the filter chamber of the filter press at a pressure of about 1.0MP, which is conducive to the free water in the sludge. After the accumulated sludge in the filter chamber reaches the design capacity of the filter press, it enters the high-pressure press section. The dryness of the dehydrated sludge is closely related to the effect of chemical conditioning and modification, as well as the filling degree of the filter chamber, the pressure boost rate and the pressure holding time.

When the chemically conditioned sludge conditioner achieves better results, the high pressure feeding and pressing can shorten the time of the whole pressing section and improve the production efficiency. Automatic discharge and backblowing of filter material (filter cloth) are completed at the same time, which can reduce the labor intensity of the controller, and improve the efficiency of the completion of the action, and maintain the effect of the filter cloth to intercept sludge and permeable water.
