Description
Technical Field
The utility model relates to the technical field of environment-friendly filter pressing, in particular to a filter pressing plate.
Background
Filter presses are used for the separation of solids and liquids. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has higher solid content and excellent separation effect. The basic principle of solid-liquid separation is as follows: the mixed liquor flows through the filter medium (filter cloth), and the solids stay on the filter cloth and gradually accumulate on the filter cloth to form a filter mud cake. While the filtrate portion permeates the filter cloth to become clear solution without solids. As the filtering process is carried out, the filter cake filtering is started, the mud cake thickness is gradually increased, and the filtering resistance is increased. The longer the filtration time, the higher the separation efficiency. Specially designed filter cloth can intercept particles with the particle size less than 1 μm. Besides good separation effect and high solid content of mud cake, the filter press can also provide a further separation process: the filtration process can be combined with an efficient washing of the filter cake, so that valuable substances can be recovered and a high-purity filter cake can be obtained.
However, in the production and operation process of the filter press, the leakage between the plates is increased after the filter plates are cleaned, and generally caused by the operation under the condition that the filter cloth, the filter plates, the pressing facilities and the oil pressure are not abnormal. After the filter cloth is cleaned and the filter cake is recovered, it is common practice to use a hydraulic pressing device to press all the filter plates, and when the pressure reaches the rated pressing force, the filter press is put into use. However, in the automatic pressing process, the filter cloth and the sealing surface of the filter plate are not perpendicular, so that the filter cloth is easily wrinkled.
