In chemistry, metallurgy and many processing industries, solid-liquid separation of fine-grained material suspensions is an important task.
The common characteristics of the industrial use of chamber filter presses are fine particle size, slow sedimentation rate, high viscosity of the slurry and poor filterability. Therefore, the chamber filter press requires a large separation area and relatively high filtration pressure. Traditional dehydration equipment can no longer meet the dehydration requirements. Now, the useful equipment for filtering fine-grained materials is the chamber filter press.
The mechanical compression transmission parts and gear box of the chamber filter press must be filled with lubricating oil; hydraulic pressure is used to check the oil storage capacity of the oil tank and the working pressure of the hydraulic station. The hydraulic oil is usually replaced once a year, and the hydraulic pressure of the filter press should be replaced. The system is used for overall cleaning. The working pressure of the hydraulic station is less than the larger working pressure of the cylinder, but the minimum value cannot be lower than the allowable value of the filter pressure. If it is too small, it will cause a lot of leakage and damage the machine.
In the initial stage of pressure filtration, the filter press became more turbid. When a filter cake is formed on the filter cloth, the filtrate will become clear. If the filtrate is turbid or clear and mixed, the filter cloth of the chamber filter press is damaged or the cloth holes deviate from the plate holes. At this moment, close the valve or stop feeding to replace the filter cloth. A small amount of leakage caused by the capillary phenomenon of the filter cloth is allowed between the filter plates.
The extremely difficult-to-process mud produced in the production process is compressed and filtered by a filter press into a relatively dry mud mass, and is directly recycled to the laterite wet mine for production and use. The chamber filter press greatly reduces the labor intensity of the operators, reduces the waste of human resources and the economic cost of the operation of the chamber filter press, on the other hand, it avoids the coagulation treatment caused by the mud overflow during the transfer process. Waste pollution has greatly reduced the environmental protection pressure of enterprises and reduced unnecessary costs. The chamber filter press has extremely high economic value and social value.
1. The chamber filter press is installed on the flat concrete. This is especially easy for users to ignore. Many users are able to find the location of the device freely, and do not pay attention to reserve enough space for future use. Using this will bring a lot of trouble, so I hope you pay attention to this.
2. Fix the foot of the thrust plate at the feed end with fixing bolts for the presser foot of the cassette filter. After positioning the anchor bolts, lock them with two nuts. The installation personnel must ensure that the beam and thrust plate remain stationary. vertical. The steps of efficient operation of the base studio filter press, including correct operation, regular maintenance and troubleshooting, require a lot of attention.
