solid-liquid separator

Working principle of solid-liquid separator:


The solid-liquid separator adopts a spiral shaft and screen made of stainless steel. Its working principle is to use a slurry pump to transport the raw fecal water into the machine. By placing a spiral shaft in the sieve, solid substances are squeezed out through the spiral, and liquid flows out from the drainage outlet through the sieve.


The correct method for cleaning the solid-liquid separator:


1. Stop the pump, only allow the main machine of the solid-liquid separator to rotate, discharge the remaining solids in the main machine, and then remove the slag plate components from the spindle box;


2. Remove the screw shaft, remove the screen, clean the screen with a steel brush, and reassemble it;


3. Be careful not to wet the control circuit of the solid-liquid separator during cleaning.


How to improve the working efficiency of solid-liquid separators?


To know how to improve a solid-liquid separator, the first step is to understand the working principle of the solid-liquid separator. The solid-liquid separator operates continuously, and its mixture of feces and water is continuously pumped into the body of the solid-liquid separator. As the external pressure increases, when the pressure exceeds a certain level, the discharge port will be opened to extrude the extrusion outlet, achieving the purpose of extruding the material. The spiral extrusion solid-liquid separator has a high degree of automation, simple operation, convenient maintenance, large daily processing capacity, low power consumption, and is suitable for continuous operation.


The host is made of high-quality stainless steel using craftsmanship and technology. Its * * components are made of alloy products through special processes, occupying a small area. It is an ideal manure treatment equipment for large cattle farms and pastures, which can greatly improve the efficiency of solid-wave separation. However, there are strict requirements for factors such as the drainage process of feces, environmental characteristics, the capacity and structure of septic tanks, and the height of drainage ditches.


The separation of solid-liquid separators can be improved through the use of materials. Firstly, there is a minimum requirement for the separation of materials, and a septic tank for storing fecal water should be built based on the process standards. Once it is found that the concentration of fecal water to be separated is too thin and the content of solidified matter is less than 5%, the chances of using solid-liquid separation are greatly reduced.


Reasons and solutions for the heating of bearings in solid-liquid separators:


Firstly, users should pay attention to the lubrication level of bearings and use high-quality high-temperature resistant lithium grease as a lubricant, as the quality of the lubricant is also one of the reasons for bearing heating. If during the inspection process, mechanical friction is accompanied by noise, mechanical components are severely damaged, and bearings are loose, it should be a bearing problem that requires replacement.


A solid-liquid separator is a high-speed chemical equipment that requires good bearings. High quality and authentic bearings can ensure the long-term normal operation of the centrifuge, with a service life of nearly 10 years.


The second is to check whether the coaxiality of the solid-liquid separator spindle is accurate. Generally speaking, we don't pay much attention to coaxiality. The main shaft tends to have a large coaxiality, which can easily cause bearing heating.


Thirdly, overload or overload may be a problem with the cooling fan or the heat generated by mechanical friction, but the important issue is whether the bearings are pure. Because some customers purchase low-priced bearings, which then cause bearing heating and heating, resulting in bearing burning and other phenomena.
